If a worker is not used to lifting and vigorous exercises, he should not attempt to do difficult lifting or lowering tasks. • Do think before acting • Place material conveniently within reach. Have handling aids available • Make sure sufficient place is cleared. • Do get a good grip on the load. • Test the weight before trying to move it. If it is too bulky or heavy, get a mechanical lifting aid or somebody else to help, or both. • Do get the load close to the body .Place the feet close to the load. Stand in a stable position with the feet pointing in the direction of movement. • Do not twist the back or bend sideways. • Do not lift or lower awkwardly. • Do hesitate to get mechanical help or help from another person. • Do not lift with the arms extended. • Do not continue lifting when the load is too heavy. Team Lifting and Carrying When two workers Carrey 1 object, they should: - Workers should do test lifting before proceeding. - They should adjust the load so that it rides level and so that each person carries an equal part of the load. - When two people carry long sections of pipes or lumber, they should walk one behind the other. Shoulder pads will prevent cutting into their shoulders and will reduce fatigue. When a Team of Workers Carrying the Object The supervisor should make sure that proper tools are used and should provide direction for the work. Frequently, whistle or direct command can single "lift", "walk", and "set down". The key to safe carrying by gangs is to make every movement in unison. Page 32 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Jacks When a jack is used, workers should do the following: - Check the capacity plate or other marking on the jack to make sure the jack can support the load. if the identified plate is missing, workers should determine the maximum capacity of the jack and paint it on the side - Inspect jacks before and after each use. When a jack begins to leak, malfunction, or show any sign of wear or defects, it should be removed from service, tagged, repaired, and tested under load. - Wear protective equipment especially protective footwear - Furnish toweling to jack operators for removing oils from their hands and from the jack handles - A heavy jack is best moved from one location to another on a dolly or special hand truck, if it has to be manually transported, it should have carrying handles. - The operating handle should never be left in the socket while a jack is being carried because it might strike another worker - Never throw or drop a jack upon the floor. Such treatment may crack or distort the metal. - If the surface upon which the jack is placed workers should set the jack base on substantial hardwood blocking (at least twice the size of the jack), so that it will not turn over, shift or sink. - Immediately wipe up spillage of any residual oil. To prevent the load from slipping, workers should avoid metal-to-metal contact between the jack head and the load. A hardwood shim should be placed between the jack head and the load. - never use wood or metal extenders .Instead they should either obtain a larger jack or should place higher blocking Hand Trucks: Hand trucks fall into two categories: two-wheeled trucks and four-wheeled trucks .If used by workers who are not trained, trucks can be the source of the following accidents: - Colliding with other trucks or obstructions - Jamming hands and feet of operators between the trucks and other objects - Running wheels of bridge plates or platforms Trucks should be pushed not pulled as this may lessen the stress to the lower back They should not be loaded so high that operators cannot see where they are going. For extremely bulky items or pressurized items as gas cylinders, strap or chain the item to the truck. Operators should place the load well forward so it will not slip, shift or fall keeping the center of gravity of the load as low as possible.

The effect is to obtain the salt of the mercaptan used in large amounts in gas odorant blends. Those salts are soluble in water. • Insert the bung , agitate the content on the drum thoroughly , wetting all interior surface by up-ending the drum 2 or 3 times and rolling it approximately 3 meters forward and back . • Place 13.5 liter of clean water in a clean plastic bucket or container, and gradually add 4.5 liter of a 13.14%sodium hypochlorite .that final solution will contain 3.79% in sodium hypochlorite. Always prepare a fresh solution to take advantage of its full activity. • Remove the bung; add carefully the 18 liter of fresh bleach (sodium hypochlorite) solution to the drum using a large funnel to avoid splashes. • Insert the bung and agitate the content of the drum thoroughly by rolling the drum approximately 3 meters forward and back. • Place drum upright, let stand for 48 hours, then remove carefully the bung and carefully smell the content of the drum to determine if the gas odorant smell has been removed. • If the gas odorant smell is still present, the amount of bleach was insufficient. Dilute 1.1 liter of bleach 13.14% of sodium hypochlorite in 8 liters of water, add those 8 liters to the drum. Continue from step 5. • Wear the proper PPE. Page 34 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Personal Protective Equipment (PPE) Purpose The Personal Protective Equipment (PPE) program has been developed to provide employees and workers with the necessary information to identify work situations that require the use of PPE, the proper selection and use of PPE, and documentation of this information. Identifying Potential Hazards in the Workplace: (Hazard Assessment) OSHA requires that employers should identify and assess the risks to health and safety present in the workplace, so enabling the most appropriate means of reducing those risks to an acceptable level to be determined. Training Prior to conducting work requiring the use of personal protective equipment, employees must be trained to know: • When PPE is necessary; • What type is necessary; • How it is to be worn; • What its limitations are; and, • Proper care, maintenance, useful life, and disposal. Employers should provide appropriate PPE and training in its use to its employees. No charge can be made to employee for the provision of PPE that is used only at work. Selection, Use and Maintenance of PPE: A- Head Protection: Prevention of head injuries is an important factor in every safety program. Head injuries are caused by falling or flying objects, or by bumping the head against a fixed object. Head protection, in the form of protective hats, must do two things: • Resist penetration; • Absorb the shock of the blow. This is accomplished by making the shell of the hat of a material hard enough to resist the blow, and by utilizing a shock-absorbing lining composed of headband and crown straps to keep the shell away from the wearer’s skull. Page 35 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Hazards on Head Electrical hazards Falling objects or collision Selection: Each type and class of head protector is intended to provide protection against specific hazardous conditions. An understanding of these conditions will help in selecting the right hat for the particular situation. Protective hats are made in the following types and classes: Type 1: Helmets with full brim, not less than 1 and ¼ inches wide. Type 2: Brimless helmets with a peak extending forward from the crown. Type 1 – Full Brim Type 2 - Peak For industrial purposes, three classes of helmets are recognized: Class A These helmets are for general service. They provide good impact protection but limited voltage protection. They are used mainly in mining, building construction, shipbuilding, and manufacturing. Page 36 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Class B Choose Class B helmets if your employees are engaged in electrical work they protect against falling objects and high-voltage shock and burns. (Electrical workers use them extensively. Class C Designed for comfort, these light weight helmets offer limited protection. They protect workers from bumping against fixed objects but do not protect against falling objects or electric shock. (This class is usually manufactured from aluminum and offers no dielectric protection). B: Eye and Face Protection Suitable eye protectors must be provided where there is a potential for injury to the eyes for face from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, potentially injurious light radiation or a combination of these. Types of Eye and Face Protection: • Safety Glasses • Safety Goggles • Face Shields • Welding Goggles • Laser Safety Glasses Selection: Each eye, face, or face-and-eye protector is designed for a particular hazard. In selecting the protector, consideration should be given to the kind and degree of hazard, and protector should be selected on that basis. Table 1. Eye and Face Protector Selection Guide: Page 37 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Operation Hazards Recommended Protectors numbers refer to Fig 1 Acetylene-burning, Sparks, harmful rays, 7,8,9 acetylene-cutting, molten metal, flying Acetylene-welding particles.

Hearing protection equipment: Its purpose to reduce the noise level to be lower the noise limits allowed in work place. Hearing protectors will always have an assigned Noise Reduction Rating (NRR), which should be printed on the packaging of each hearing protector. NRR is the amount of decibels by which a given device will reduce noise exposure, by subtracting the NRR value from the noise exposure levels. OSHA requires subtracting 7 from the NRR as a safety factor. 1. Ear Muffs It is covering the external ear, making a sound barrier and protect ear from high levels of noise where it can reduce it by 15 – 35 dB. It is used when noise in work place is 90 – 120 dB. 2. Ear Plugs Placed at ear canals and manufactured from plastic or rubber and can reduce the noise by 20-30 dB and used for places which have noise of 85 – 115 dB. In some places, which have a high level of noise, ex. 130 dB ear muffs can be used with ear plugs to reduce noise about 50 dB. Page 39 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction C: Foot Protection Statistics showed that most of the workers in selected occupations who suffered foot injuries were not wearing protective foot-ware. For protection of feet and legs from falling or rolling objects, sharp objects, molten metal, hot surfaces, and wet slippery surfaces, workers should use appropriate foot guards, safety shoes, or boots. Safety shoes should be sturdy and have an anti-resistant toe. In some shoes, metal insoles protect against puncture wounds. D- Respiratory Protection Respiratory protective devices fall into two classes: 1. Air Purifying Devices 2. Air Supplying Devices Air-supplying Devices Air-supplying devices are the class of respirators that provide a respirable atmosphere to the wearer, independent of the ambient air ex. Self-contained breathing apparatus (SCBA) Which provide complete respiratory protection against toxic gases and an oxygen deficiency. The wearer is independent of the surrounding atmosphere because he or she is breathing with a system that is portable and admits no outside air. Page 40 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Air Purifying Devices The various types of air-purifying devices include:  Mechanical-filter cartridge  Chemical-cartridge  Combination mechanical-filter/chemical-cartridge  Gas Masks  Powered Air-Purifying Respirators (PAPR) The air-purifying devices cleans the contaminated atmosphere. Chemicals can be used to remove specific gases and vapors and mechanical filters can remove particulate matters. This type of respirator is limited in its use to those environments where the air contaminant level is within the specified concentration limitation of the device. These devices do not protect against oxygen deficiency (percentage of oxygen by volume is less than 19.5 percent oxygen). Page 41 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Proper Selection: Respirators shall be selected based on hazards to which the worker is exposed. In selecting the correct respirator for a given circumstance, many factors must be taken into consideration:  The nature of the hazard  Location of the hazardous area  Employee’s health  Work activity  Respirator characteristics, capabilities, and limitations. In order to make subsequent decisions, the nature of the hazard must be identified to ensure that an overexposure does not occur. One very important factor to consider is oxygen deficiency. Air-purifying respirators can be used only at atmospheres containing greater than 19.5 percent oxygen. Training and Fitting: The user must be instructed and trained in the selection, use and maintenance of respirators. Every respirator user shall receive fitting instructions including demonstrations and practice in how the respirator should be worn, how to adjust it, and how to determine if it fits properly. Fit Testing: Fit testing is done to find both a style and a size of respirator that fits the individual best and is most comfortable. There are two types of fit testing: Quantitative fit testing and qualitative fit testing. Field Testing: Once the fit test has been performed and a respirator selected, the user should perform “field tests” on his respirator each time before entering the toxic atmosphere. These consist of both a negative-pressure test and a positive-pressure test. These tests apply to respirators with either a cartridge, canister, or filter. Negative-Pressure Test: In this test, the user closes off the inlet of the canister, cartridge(s), or filter(s) by covering with palm(s) or squeezing the breathing tube; inhales gently so that the face-piece collapses slightly; and holds the breath for about 10 seconds. If the face-piece remains slightly collapsed and no inward leakage is detected, the respirator is probably tight enough. Page 42 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Positive-Pressure Test The positive-pressure test is conducted by closing off the exhalation valve and exhaling gently into the face-piece. The fit is considered satisfactory if slight positive pressure can be built up inside the face-piece without any evidence of outward leakage. Medical considerations The workers who must use respirators according to job nature must make a medical examination to eliminate individuals who are suffering from (chronic respiratory system diseases – cardiac diseases – difficult breathing diseases – hearing weakness). Doctor specify the individuals who can use respirators and others who cannot according to the medical examination. Cleaning and storage of respirators - Disassembly the respirator parts and wash it with detergents, hot water and brush then wash the parts with cold water, after that leave the parts to be dried in a clean and dry place. - Do not use organic solvents in washing because it can damage the plastic parts. - Be sure it is washed well with water and no traces of soap exists because it may make irritation to the user. - Storage of respirators is done in a clean place for saving from dirt and dusts. - After washing respirators, keep them in sealable plastic bags. Page 43 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction E- Safety belts and lifeline They are used while working at heights for workers safety, also now using the parachute belts instead of regular belts. In case of confined spaces working, use a safety harness and lifeline for getting the worker outside in a straight position, which eliminate injuries in emergencies. F- Hand Protection: Employees are required to use appropriate hand protection when their hands are exposed to hazards such as: • Absorption of harmful substances. • Severe cuts or lacerations. • Severe abrasions. • Punctures. • Chemical burns. • Thermal burns. • Harmful temperature extremes (cold/heat). Kinds of Protective Gloves: Gloves made from a wide variety of materials are designed for virtually every workplace hazard. They may be divided into groups as the following: 1- Metal Mesh, Leather, or Canvas Gloves: Sturdy gloves made from metal mesh, leather, or canvas provide protection against cuts, burns, and sustained heat. Page 44 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction 2- Chemical-and Liquid-Resistance Gloves Gloves made of rubber (latex, nitrile, or butyl), plastic, or synthetic rubber-like material such as neoprene protect workers from burns, irritation, and dermatitis caused by contact with oils, greases, solvents, and other chemicals. The use of rubber gloves also reduces the risk of exposure to blood and other potentially infectious substances. Some common gloves used for chemical protection are described below. (In addition, table 4 rates various gloves as protectors against specific chemicals.) 3- Heat resistance Gloves These gloves provide protection against heat like steam pipes and hot glassware in laboratories or welding operations. G- Body Protection Overalls and aprons are used at working near machines or in workshops. Plastic safety suits and coats are used for body protection against chemicals like acids and bases.

Page 46 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Purging The inert gas used in purging media must have the following characteristics: a) Inflammable. b) Not support combustion c) Contain less than 2% oxygen. Inert gases most commonly used for purging are Carbon Dioxide, nitrogen, or mixtures of the two. Notes must be considered in Purging Operation:  Using blank behind valve to isolate the part of the pipeline, which will be purged from the part that will be in service.  The inert gas must be adequate and efficient.  Devoid of purge, gas from moisture or other constituents, which might contaminate the material, protected.  The vapors from enclosures being shall be vented to a safe point outside of enclosures and away from ignition sources.  After the completion of purging operation and the procedure of work which had been prepared and reaching to the end point, a test must be done to the air around the place of purging to ensure that there is no gases or condensate or leakage or any circumstances can lead to any chemical reaction can form combustible substances or self-ignition. Vent Pipes These pipes used to vent the gases present in the equipment to a point at which a dilution for these gases without any harm for the labors. Therefore, it is advised that the lowest height for this joining is 3 m from the surface of the earth or from the nearest platform. also, the size of the vents is an important factor in identifying the speed of gas vented, and for safety the speed of the gas out from these vents at least ( 3- 4m/s ) and to consider that the total of area of the vent points is less than the points entering purging media.

Work permit is not just a permit to do dangerous works; its essential part of the system, which identify how can the job, is done safely. Work permit is a document, which gives the right for worker to do his job, taking into account all risks, precautions, equipment that are exist, and how to do his job safely. The getting of work permit does not also mean the process is safe, it must mention that well trained personnel are controlling all hazards by means of control measures and precautions. The work permit is based on written procedure used to control special types of works that have potential hazards and it is a communication method between sites, workers, supervisors, and management. Instructions for the permit issuance: General: a- Specify the responsibilities of supervision personnel for every process and precautions to take into account. b- There must be a clear instructions and training for using and issuance of work permits. c- The system of work permit must be followed up. * The following points have to be clear stated in permits: 1- Specify the department or sector responsible for the job, type of job, and location of the job. 2- Specify type and nature of job to all related personnel with clarification of all related hazards. 3- Illustration of all control measures required to protect from possible hazards and risks. 4- Be sure that worker is qualified for the job also be sure that a continuous supervision is applied and qualified person reviews all precautions. 5- Illustration of various work procedures on site and temporary work stopping procedures. 6- Illustration of the followed procedures for elongation of working period’s more than one shift also be sure that all procedures that guarantee that the job is safe are fully illustrated. Page 64 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction Permit preparation 1- it's very important that all activities related to the job to be taken into account to avoid any risks obtained from the job , that is done by one who is responsible for the job ( site manager ) who monitor the issuance of permits till job is finished . In addition, it is important in some cases to participate more than one in the responsibility, each in his field and site manager has the all authority for supervision for all responsible personnel. 2- The permit requires a good planning from all related personnel, where they must be informed about the work places that may be affected by the work and taking all precautions to avoid any effect could be happened to any of work activities. Also giving the time required to identify all risks, control measures, and preparation of site for work, the supposed technical method to achieve that is the procedure of: “Job Hazard Analysis “. 3- The most important stage of permit issuance is the risk assessment which done by permit maker with work supervisor also may be other specialists participate in the risk assessment , the following have to be done at the assessment: a- Get the detailed information about the process to be done from supervisor with taking into account all alternatives that can achieve the work safely, like timing, method of work… Etc. b- Taking into account all risks that may arise from handling materials and working by equipment. c- Evaluation of difficulties and expected effects on working environment also expected hazards that affect the work. * Types of Works Types of works include works such as maintenance, repairing, inspection, testing, construction, re-construction, machines disassembly, modification and cleaning. * Activities Interference The main aim is to verify that no hazardous interference between activities that may contain risks for people or equipment. Page 65 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction * Permit Validity It is important to specify the validity of work permit to the work permit system under control also it's favorable to eliminate permit at the end of the working shift and issue a new one if the job is continued for more than one shift . * Isolation It is an essential part of safely working system; also, each company makes its own isolation procedures based on working activities and associated risks. * Precautions You must know the nature, type of job for defining the required precautions that will be wrote and reviewed in its form, and each supervisor must be sure that all precautions are implemented. * Gas Test A test for gas leakage must be done on sites, which contain flammable or toxic gases or expected decreasing / increasing of oxygen. The results of the test must be recorded in the permit. * Approval (signature) The number of work permit approval personnel are specified according to nature and type of work and permit, as a minimum requirement the permit issuance person and the work supervisor must sign on the permit and any other person who participated in the permit issuance and if the responsibility is changed to other personnel, he must sign on the permit. * Process - permit using The permit must be communicated to all related parties or personnel and copies of permit must sent to these related parties. - Permit validity The permit issue personnel must re-evaluate the conditions of work that he issued for the permit at the first time and be sure that conditions are not changed – (it is common that this evaluation is done at the end of each work shift). - Changing Shifts The points of changing shifts are considered very critical for work permit and any fault of information transfer is a reason for many accidents. In addition, information transfer methods are: Page 66 of 71 Date: March. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Health, Safety and Environment Procedures Manual for Pressure Reduction Station Construction a- Work permit logbook. b- Files of permits. c- Signs and information boards. d- Computer screen. - Emergency Procedures The permit must contain the followed procedures in case of emergencies like limitations of some activities …etc. and re-evaluate the job which the permit is issued for, to ensure that conditions are not changed by existing emergency. - Permit Monitoring The monitoring must not be stopped to ensure not all the conditions are changed along with the process progress. - Finishing job in permit When the job is finished, the permit copies are collected and sent back to the issuance parties, which will sign on the permit with the supervisor stating that the job is finished; also other related parties are informed. - Site Inspection The permit party’s representative must make a site inspection after the job to ensure that it is leaved in good conditions. - Coming back to operation mode There must be some procedures for equipment to come back to operating mode like: a- The work on machines is finished. b- The facilities and equipment are leaved in safe and good conditions. c- All isolation and outreaches procedures are terminated. d- The responsible personnel must accept officially the existing conditions of the facility and equipment. - Records The permits must recorded in a specified logbook.

INTRODUCTION Air quality and noise monitoring has been carried out as part of the baseline description for the Environmental and Social Impact Assessment of the proposed gas pressure reduction station(PRS) project located in Zefta city –Al Gharbia governorate. Since the (PRS) will be constructed in its current location, This location was set as suitable location for ambient air quality and noise level monitoring. The selection of the active air measurement location is based on the nature of the surrounding activities, the location of the nearest sensitive receptors1 (such hospitals, schools, protectorates, … etc.) with respect to the project plots, prevailing wind direction, site topography and the future layout of the proposed project components. Moreover, the selection is based on the guidelines stated in the American Society for Testing Materials (ASTM) reference method. Accordingly, environmental measurements have been taken at the PRS location as a benchmark to be able to assess the impacts of the PRS construction and operation activities on air quality. Air quality monitoring has been undertaken for the pollutants of primary concerns (CO ,NO2, SO2, T.S.P and PM10), in order to get the baseline of the air quality as part of the environmental impact assessment required, where a one-hour average measurements were conducted for carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2), Total Suspended Particulates (T.S.P) and particulate matter (PM10) for one specific sensitive location in the proposed site of pressure reduction station under construction, where the air quality compared with the national guidelines for all the analysed parameters. The site specific air quality measurements were conducted using Standard ambient air quality monitoring instruments under the supervision of experienced specialists. Noise levels were conducted as per the international standard using type 1 precision noise level meter. 1.1 Objectives The overall objectives of this monitoring round are to:  Assess/confirm compliance of the air quality in the baseline environment with relevant national and international guidelines;  identify any non-compliance issues, if any; and  Provide general conclusions based on analysis results. The objectives of the ambient air quality Monitoring activities conducted at the proposed site are:  To verify compliance with authorized discharge limits and any other regulatory requirements concerning the impact on the public and the environment due to the normal operation of a practice or a source within a practice; 1 None were observed during the site visit. Page | 2  to establish air quality baseline which will assist in the estimation of the project impact on the local physical, biological and social environment ;  To check the conditions of operation and the adequacy of controls on discharges from the source and to provide a warning of unusual or unforeseen conditions and, where appropriate, to trigger a special environmental monitoring program. 1. 2 S cop e o f Wo r k  The scope of work of the present monitoring includes the sampling and analysis of active air and noise in the surrounding area as to distinguish whether air quality is impacted by the project activities or not.  The measurement will be conducted in the herein location within the boundaries of the sensitive receptor. 1.2.1 Sampling strategy The selection of the active air measurement location is based on the prevailing wind direction; site Topography, the future layout of the proposed project components and the location of the nearest sensitive receptors with respect to the project rout.

METHODOLOGY 3.1 Ambient air quality Ambient Air Quality Monitoring equipment is an integrated system of which includes several analyzers with data recording devises. A typical system would include gas analyzers for ambient air analysis, data recording, and signal transmission instrumentation. Figure 3-1 ambient air quality monitoring system Ambient air pollutants   The most common gaseous air pollutants (also known as "criteria pollutants") are carbon monoxide, sulfur oxides, and nitrogen oxides. These pollutants can be harmful to health and the environment, and cause property damage. To acquire baseline information on background levels of Thoracic Particulates, the team conducted for one-hour active sampling using a dust sampler. The sampler measures the respirable fraction of airborne dust (of particle size 0.1 to 10 μm) with a measuring range of 0.001 to 400 mg/m3 and an accuracy of ± 5 % of the reading. The levels measured and recorded would serve as baseline values for reference during future monitoring activities.

The following devices were used during the first round of noise level measurements:  Two B & K 2238 Mediator, Integrating Sound Level Meters, Type I (precision grade), compliant with IEC 1672 Class 1 standard;  B & K 4198 Outdoor Weatherproof Microphone Kit;  GPS unit (Garmin MONTANA 650); and  Digital Camera. Noise monitoring measurements included recording the following parameters using a Type 1 precision grade hand-held sound-level meters:  Equivalent continuous noise level (LAeq)  95th percentile noise level (LA95)  90th percentile noise level (LA90)  50th percentile noise level (LA50)  10th percentile noise level (LA10)  Peak sound pressure level (LCpeak) The following equation5 is the main equation used to calculated day night equivalent sound pressure level: n 1 Lden  10 log n  10 i 1 0.1( Li  Di ) Where Lden  Day Night Equivalent , L i  The hourly Leq , Di  the addition for the different periods of the day , n  number of measured hours . The sound level meters were calibrated before sound measurements to ensure reliability and precision. GPS coordinates and meteorological conditions were recorded using hand-held kits at all locations prior to the start of noise measurements. It is anticipated that most of these locations would remain the same for the purpose of pre-construction, construction, performance guarantee tests and operation monitoring. Error!

RESULTS The following tables present the results for ambient air quality measurements conducted at the proposed PRS location. The air quality at the proposed site of the proposed PRS is exhibiting acceptable levels of classic air pollutants in fact the levels are way below the international guidelines. Generation and dispersion of dust from increased vehicle traffic, especially during the rash hour, may reduce visibility, relative to baseline levels, and, together with combustion engine emissions, may affect ambient air quality. Concentration of dust particles, both total suspended particulate and respirable particulate matter and other pollutants from open burning, emissions from equipment and machinery used in transportation, various activities of operations and emissions from vehicles used to transport passengers also contribute to air pollution. These impacts may affect the human environment and, typically, arise during the preparation phase and, to a much lesser extent, during the operation phase, requiring monitoring and assessment of the natural and man-made air pollutants. One hour average results for 8 hours continuous measurements are shown in Table 4-1 for all the measured parameters Table 4-1 one hour average results NO NO2 NOx SO2 CO PM10 T.S.P Time 3 3 3 3 3 3 (µg/m ) (µg/m ) (µg/m ) (µg/m ) (mg/m ) (µg/m ) (µg/m3) 10:AM 15.7 12.3 28 7.5 0.7 11:00 13.2 11,7 24.9 8.6 0.8 12:00 17.3 13.1 30.4 8 0.8 13:00 16.8 12.6 29.4 7.1 0.7 80 99 14:00 19.1 13.2 32.3 7.6 0.8 15:00 20.1 17.4 37.5 8.2 1 16:00 18.6 16.9 35.5 9.1 0.9 17:00 19.3 15.7 9.3 9.3 0.8 Limits 150 200 150 350 30 (mg/m3) 150 230 4.1 Analysis of air quality Results In general there are two main factors affecting the ambient air concentration of a certain pollutant emitted from a certain source or sources in a selected area:  The intensity of the emissions (e.g. concentration and flow rate) from the source or sources.  The uncontrollable atmospheric dispersion conditions which include but not limited to (wind speed, wind direction, temperature, humidity, rain fall, atmospheric turbulence, solar radiation intensity and atmospheric pressure). All the recorded results showed compliance with the national and international guidelines for ambient air quality moreover most of the data recorded were way below the guidelines which indicates that the ambient air quality in the project areas is one of the clear areas in Egypt in terms of ambient air quality which can be attributed to the absence of any major industrial sources. Moreover, the area is agricultural area with a very scarce source for any pollution other than the nearby the route. 5.

Version number / modification: .................. Date:…./…../ …… Approval:…………………… Grievance and Redress Mechanism & Complaint Form 1. Introduction EGAS and the LDCs are committed to preventing, limiting and, if necessary, remedying any adverse impacts caused by its activities on local populations and their social and physical environment. Identifying, preventing and managing unanticipated impacts are facilitated by a grievance redress mechanism (GRM). As the World Bank’s governance and anticorruption (GAC) agenda moves forward, grievance redress mechanisms (GRMs) are likely to play an increasingly prominent role in Bank-supported projects. The GRM was designed in order to handle all grievances during the construction and operation phases. The aggrieved person has the full right to lodge his complaint anonymously. However, this might cause a challenge to inform him about any corrective procedures. Additionally, if the complaint is related to service seeking, the aggrieved person should provide full information about himself and about his residential unit. All information about GRM will be made available on the contracting offices during the construction phase and on customer services offices during the operation phase. 2. GRM Objectives Effective grievance management helps to:  Build trust through having a dialogue with stakeholders.  Detect weak signal and propose solution.  Reduce risk of conflict between the affiliate and local communities.  Reduce risk of litigation by seeking fair solutions through mediation in the event of an established impact.  Identify and manage unanticipated impacts of operation.  Avoid delays to operations and additional costs.  Avoid future impacts through analysis of weak signals. 3. GRM Cycle The grievance received via any of communication channels and tiers will follow the following cycle. The aggrieved person has the full right to submit his grievance to any of the assigned tiers to be mentioned in section 4 of this annex. The aggrieved person also has the full right to submit his grievance to any entity he prefers i.e the Minister of Petroleum, the Page 1 of 10 Governorate …etc. It is essential to mention that the acknowledgement of grievance should not exceed two working days. Figure 1 : Grievance cycle Page 2 of 10 4. GRM tiers The proposed mechanism is built on three tiers of grievances: - The foreman working on the ground in PRS site in Zefta, - The project manager in PRS site in Zefta, - The regional department of Egypt Gas in Gharbeya Governorate The aggrieved person has the full right to immediately use tier 2 or 3 upon his convenience and there is no need to exhaust the first tier. Additionally, he can resort to any other governmental entities i.e. Ministry of Petroleum. He/ She also have the full right to bring a lawsuit without resorting to any of the grievances tiers.  First tier of grievances In order to ensure high level of responsiveness to the local communities, it is essential to ensure that a local grievance mechanism is functioning and that the communities are aware of it. Egypt Gas has assigned a Social Development Officer (SDO) (can be more than one) who will be working closely with the assigned SDO of EGAS. It is the responsibility of Egypt Gas SDO to ensure that the GRM system is widely known and well explained on the local level. Moreover, he/she will follow up on the complaint until a solution is reached. The turnaround time for the response/resolution should be 15 business days and the complainant should know that he/she should receive response by then. The grievances should be presented to the following: - The foreman working on the ground in Gharbeya, - The project manager in Gharbeya, - The regional department of Egypt Gas in Gharbeya Governorate It is worth noting that most of the previous experience of EGAS is suggesting that complaints are usually handled efficiently and resolved on the local level. However, the management of the complaints including level of responsiveness, providing feedback and the documentation of the complaints needs to be significantly strengthened. In case the problem is not solved, the complainant may reach out to the second level of grievance.  Second tier of grievances: If the aggrieved person is not satisfied with the decision of the first tier, they can present the case to Egypt Gas headquarter. Complaint form is presented below. SDO where they should provide resolution within 15 business days, following is the second level of grievances: 1. The Social Development Officer in Egypt Gas headquarter will handle any complaints raised to him/her. 2. Egypt Gas headquarter SDO should receive the unsolved problems. Thereafter, the SDO gets in contact with the petitioner for more information and forwards the complaint to the implementing entities for a solution. 3. The SDO in Egypt Gas headquarter might communicate with the site SDO for more clarification and coordination Page 3 of 10 4. The SDO should follow the complaints and document how they were solved within 15 business days. 5. The SDO should update the complainant on the outcome of his/her complaint.  Third tier of grievances: If the aggrieved person is not satisfied with the decision of the SDOs of Egypt Gas at Stage 2, they can present the case to EGAS SDO where they should provide resolution within 15 business days. The following section presents the third level of grievances: 1. The Social Development Officer in EGAS will handle all complaints. He should receive the unsolved problems. Thereafter, they get in contact with the petitioner for more information and forwards the complaint to the implementing entities for a solution. 2. The SDO should follow the complaints and document how they were solved within 15 business days. 3. The SDO should update the complainant on the outcome of his/her complaint. 5. Grievance channels Due to the diversity of the context in different Governorates and the socioeconomic characteristics of the beneficiaries, the communication channels to receive grievances were locally tailored to address all petitioners concerns and complaints. The following are the main channels through which grievances will be received: 1. Foremen act as the main channel for complaints. They are always available on the construction sites. However, complaints raised to him/her are mostly verbal. Thus, s/he should document all received grievances in writing form using a fixed serial number that the complainant should be informed about to be able to follow up on the complaint 2. Hotline: 129 is the hotline in Egypt Gas. 3. The SDO within the LDC and EGAS 4. Email. info@Egypt Gas.com.eg Trustworthy people, community leaders and NGOs/CDAs will be an appropriate channel to guide petitioner about the various tiers of grievances, particularly, in rural areas. Response to grievances Response to grievance will be through the following channels 1. The response to grievances should be through an official recognized form to ensure proper delivery to the complainant. It is the responsibility of the SDOs to ensure that complainants were informed about the results of handling their complaints. 2. Response to grievances should be handled in timely manner as mentioned above, thereby conveying a genuine interest in and understanding of the worries put forward by the community. 3. EGAS and Egypt Gas should maintain record of complaints and results. Page 4 of 10 6. Monitoring of grievances All grievances activities should be monitored in order to verify the process. The monitoring process should be implemented on the level of EGAS and the LDC (both in the site and in the headquarter). The following indicators will be monitored: Means of verification and indicators o Number of received grievances monthly (Channel, gender, age, basic economic status of the complainants should be mentioned) o Type of grievance received (according to the topic of complaint o Documentation efficiency o Time frame for acknowledgment o Number of grievances solved and closed o Feedback offered to the grievances o Number of unsolved grievances and the reasons behind not solving them o Time consumed to solve the problem o Grievances escalated to 2nd and 3rd tiers o Grievances escalated to court o Dissemination activities undertaken o Total number of brochures distributed (if any) o Total number of awareness meetings conducted (if any) 7. Institutional Responsibility for the Grievances The entity responsible for handling grievances will mainly be the Environmental Affair Department within the implementing agency (EGAS). The Social Development Officer (SDO) working within EGAS in cooperation with the Egypt Gas will address all grievances raised by community members. The main tasks related to grievances of the SDOs on the various levels are: 1. Raise awareness about channels and procedures of grievance redress mechanisms 2. Collect the grievances received through different communication channels 3. Document all received grievances 4. Transfer the grievance to the responsible entity 5. Follow up on how the problem was addressed and solved 6. Document, report and disseminate the outcome of received grievances 7. Ensure that each legitimate complaint and grievance is satisfactorily resolved by the responsible entity 8. Identify specific community leaders, organizations and citizen groups required to enhance the dialogue and communication through a public liaison office to avoid or limit friction and respond effectively to general concerns of the community 9.

The PRMS owned by The Egyptian Natural Gas Holding Company “EGAS” and operated by Egypt Gas Company. The scope of work includes performing frequency assessment, consequence modeling analysis and Quantitative Risk Assessment of Zefta PRMS in order to assess its impacts on the surroundings. The main objective of the Quantitative Risk Assessment (QRA) study is to demonstrate that Individual Risk “IR” for workers and for public fall within the ALARP region of Risk Acceptance Criteria, and the new Zefta PRMS does not lead to any unacceptable risks to workers or the public. QRA Study has been undertaken in accordance with the methodology outlined in the UKHSE as well as international regulations and standards. QRA starts by Hazard Identification (HAZID) study, which determines the Major Accident Hazards (MAH) that requires consequence modelling, frequency analysis, and risk calculation. In order to perform consequence-modelling analysis of the potential hazardous scenarios resulting from loss of containment, some assumptions and design basis have been proposed. Three scenarios of the release have been proposed: 1. Gas Release from the inlet / outlet pipeline. 2. Gas Release from the off-take point. 3. Leak from odorant tank. The QRA has been performed using DNV Phast software (Ver. 7.21) for consequence modelling of different types of hazardous consequences. Weather conditions have been selected based on wind speed and stability class for the area detailed weather statistics. The worst case weather conditions has been selected represented by wind speed of 4 m/s and stability class "D" representing "Neutral" weather conditions, in order to obtain conservative results. The prevailing wind direction is North (N) & North West (NNW).

The major hazards that extend over site boundary and/or effect on workers / public were used for Risk Calculations. Event Tree Analysis (ETA) is an analysis technique for identifying and evaluating the sequence of events in a potential accident scenario following the occurrence of an initiating event. ETA utilizes a visual logic tree structure known as an event tree (ET). ETA provides a Probabilistic Risk Assessment (PRA) of the risk associated with each potential outcome. ETA has been used for scenario development.

The PRMS operated by Egypt Gas Company in order to advice protective measures for minimizing risk up to acceptable level. As part of this review, a QRA study conducted for the following objectives:  Identify hazardous scenarios related to the most critical unexpected event(s).  Determine the likelihood of the identified scenarios;  Model the potential consequences of the identified scenarios;  Determine the Potential risk of fatality resulting from the identified hazardous scenarios. The proposed study should also identify existing arrangements for the prevention of major accidents and their mitigation. This would involve emergency plan and procedure for dealing with such events. PETROSAFE selected to carry out this study, as it has the experience in conducting this type of work. PETROSAFE is also empowered by the Egyptian General Petroleum Corporation “EGPC” to identify and evaluate factors that relate to Occupational Health & Safety and Environmental Protection.

The impact of the blast wave on structure near the explosion known as blast loading. The two important aspects of the blast loading concern are the prediction of the magnitude of the blast and of the pressure loading onto the local structures. Pressure loading predication as result of a blast; resemble a pulse of trapezoidal or triangular shape. They normally have duration of between approximately 40 msec and 400 msec. The time to maximum pressure is typically 20 msec. Primary damage from an explosion may result from several events: 1. Overpressure - the pressure developed between the expanding gas and its surrounding atmosphere. 2. Pulse - the differential pressure across a plant as a pressure wave passes might cause collapse or movement, both positive and negative. 3. Missiles and Shrapnel - are whole or partial items that are thrown by the blast of expanding gases that might cause damage or event escalation. In general, these “missiles” from atmospheric vapor cloud explosions cause minor impacts to process equipment since insufficient energy is available to lift heavy objects and cause major impacts. Small projectile objects are still a hazard to personnel and may cause injuries and fatalities. Impacts from rupture incidents may produce catastrophic results.

Existing site infrastructure, weather, and Study Geotechnical data also required, these being a source of external hazards. (HAC) When electrical equipment is used in, around, or near an Hazardous atmosphere that has flammable gases or vapors, flammable Area liquids, combustible dusts, ignitable fibers or flying’s, there is Classification always a possibility or risk that a fire or explosion might occur. Those areas where the possibility or risk of fire or explosion might occur due to an explosive atmosphere and/or mixture is often called a hazardous (or classified) location/area. (IR) The risk to a single person inside a particular building. Maximum Individual individual risk is the risk to the most-exposed person and assumes Risk that the person is exposed. Jet Fire A jet fire is a pressurized stream of combustible gas or atomized liquid (such as a high-pressure release from a gas pipe or wellhead blowout event) that is burning. If such a release is ignited soon after it occurs, (i.e., within 2 - 3 minutes), the result is an intense jet flame. This jet fire stabilizes to a point that is close to the source of release, until the release stopped. A jet fire is usually a very localized, but very destructive to anything close to it. This is partly because as well as producing thermal radiation, the jet fire causes considerable convective heating in the region EGAS.HSE.QRA.Study.014/Zefta-Egypt.Gas.PRMS.No.011/2018/QRA/MG/MS/WS-DNV-PHAST.7.21/UAN.152,414-PETROSAFE-Draft.Report-Rev.00 Prepared By: Page 22 of 114 PETROSAFE Date: Nov. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Quantitative Risk Assessment “QRA” Study For Zefta Pressure Reduction & Metering Station beyond the tip of the flame. The high velocity of the escaping gas entrains air into the gas "jet" causing more efficient combustion to occur than in pool fires. Consequentially, a much higher heat transfer rate occurs to any object immersed in the flame, i.e., over 200 kW/m2 (62,500 Btdsq. ft) for a jet fire than in a pool fire flame. Typically, the first 10% of a jet fire length is conservatively considered un-ignited gas, as a result of the exit velocity causing the flame to lift off the gas point of release. This effect has been measured on hydrocarbon facility flares at 20% of the jet length, but a value of 10% is used to account for the extra turbulence around the edges of a real release point as compared to the smooth gas release from a flare tip. Jet flames have a relatively cool core near the source. The greatest heat flux usually occurs at impingement distances beyond 40% of the flame length, from its source. The greatest heat flux is not necessarily on the directly impinged side. kW/m2 Kilowatt per square meter – unit for measuring the heat radiation (or heat flux). LFL / LEL Lower Flammable Limit / Lower Explosive Limit - The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in presence of an ignition source.

The approach adopted has involved the following stages:  Identification of hazardous materials,  Establishment of maximum total inventories and location. During the site visit by the study team, the overall functioning of the site discussed in some detail and the Companies asked to provide a complete list of holdings of hazardous materials. A preliminary survey notes was issued by the team, as a private communication to the company concerned, and this formed the basis for subsequent more discussion and analysis. From the PRMS design model provided by the client, it was impractical to examine in depth all possible failure modes for all parts within the time allowed for this study. Instead, only those potential failures, which might contribute, either directly or indirectly, to off-site risks were examined. 2.0- Risk Assessment As the PRMS designed and prepared for construction, so it was therefore necessary for the study team to identify and analyse the hazards potential from first principles the routes by which a single or multiple accident could affect the community or neighbouring. The terms of reference required the team to investigate and determine the overall risk to health and safety both from individual installations and then foreseeable interactions. The assessment of risk in a complex situation is difficult. No method is perfect as all have advantages and limitations. It was agreed that the quantitative approach was the most meaningful way of comparing and evaluating different risks. The risk assessment framework shown in Figure (1) used for the study.

In this study, Natural Gas (Mainly Methane CH4) was considered. There are several types of consequences to be considered for modelling, these include Gas Dispersion (UFL - LFL - 50 % LFL) / Heat Radiation / Explosion Overpressure modeling, also each of these scenarios described in the following table: Table (1) Description of Modeling of the Different Scenario Discharge Modeling Modeling of the mass release rate and its variation overtime. Radiation Modeling Modeling of the Thermal radiation from fires. Dispersion Modeling Modeling of the Gas and two-phase releases. Overpressure Associated with explosions or pressure burst. Toxic hazards are considered as result of releases / loss of containment for which discharge modeling and gas dispersion modeling are required. The hazard ranges are dependent upon the condition of the release pressure and rate of release. There are a number of commercial software for modeling gas dispersion, fire, explosion and toxic releases. PETROSAFE select the DNV PHAST Ver. 7.21 Software package in modeling scenarios. The software developed by DNV in order to provide a standard and validated set of consequence models that can be used to predict the effects of a release of hydrocarbon or chemical liquid or vapour.

In order to do this, we need firstly to define a performance standard and secondly, to be able to analyse the effectiveness of the arrangements in a manner which permits a direct comparison with these standards. The defining of performance standards undertakes at the following three levels:  Policy-based  System  Technical Where the present work is mainly concerned with the assessment against the standards associated with the first two levels. The policy-based performance standard relates to this objective to provide a working environment, where the risk to the individual reduced to a level that is ALARP. This performance standard is therefore, expressed in the form of individual risk and the arrangements for managing this risk should result in a level of ‘Individual Risk’, based on a proposed Tolerability Criteria, Figure (2).

It should be noted that this criteria proposed only as a guideline. Risk assessment is no substitute to professional judgement. Table (2) Proposed Individual Risk (IR) Criteria (per person/year) Risk Level Workers Public Intolerable > 10-3 per person/yr. > 10-4 per person/yr. Negligible > 10-5 per person/yr. > 10-6 per person/yr. 1 in 10,000 1 in 1000 ALARP ALARP Region Region 1 in 100,000 1 in 1 miillion Individual Risk to Personnel Individual Risk to the Public Figure (3) Proposed Individual Risk Criteria Workers would include the Company employees and contractors. The public includes the public, visitors, and any third party who is not directly involved in the Company work activities. On this basis, we have chosen to set our level of intolerability at Individual Risk for workers of 1 in 1,000 per year, and we define an individual risk of 1 in 100,000 per year as broadly acceptable. Consequently, our ALARP region is between 1 in 1,000 and 1 in 100,000 per person/year. It is important to ensure that conflict between these subordinate standards and those stemming from international codes and standards are avoided and that any subordinate standards introduced are at least on a par with or augment those standards, which are associated with compliance with these international requirements. These system level performance standards are included as part of EGAS.HSE.QRA.Study.014/Zefta-Egypt.Gas.PRMS.No.011/2018/QRA/MG/MS/WS-DNV-PHAST.7.21/UAN.152,414-PETROSAFE-Draft.Report-Rev.00 Prepared By: Page 31 of 114 PETROSAFE Date: Nov. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Quantitative Risk Assessment “QRA” Study For Zefta Pressure Reduction & Metering Station the summaries from the QRA. These used as the basis for assessing the suitability and sufficiency of Egypt Gas Site arrangements for both protecting personnel on site and members of public from major hazards and securing effective response in an emergency. Failure to meet acceptance criteria at this level results in the identification of remedial measures for assessment both qualitatively and quantitatively. The analytical work use a system analysis approach and divided into a number of distinct phases:  Data collection, including results from site-based qualitative assessments.  Definition of arrangements.  Qualitative evaluation of arrangements against a catalogue of fire and explosion hazards from other major accident hazards.  Preparing of event tree analysis models.  Consolidation of list of design events.  Analysis of the effect of design events on fire, explosion and toxic hazard management and emergency response arrangements.  Quantification of that impact in terms of individual risk. The main model would base on a systems approach, and it takes the following form:  Estimates of incremental individual risk (IIR) per person/yr.  Is caused-consequences based.  Uses event tree analysis to calculate the frequency of occurrence.  Estimates incremental individual risk utilizing event tree analysis, based on modeling the emergency response arrangements from detection through to recovery to a place of safety.

The technique of Quantified Risk Assessment ‘QRA’ requires data in the form of probability or frequency to be estimated for each input event. Ideally, data relating to hardware failures and human error that are specific to each plant should be obtained from the company’s maintenance and historical records. Unfortunately, records available were not in the form that allows data relevant to this study to be obtained. Therefore, other sources of data were used as a basis for failure/error scenarios. The sources of information and data are shown in the References section of this report. Identification of Scenarios Leading to Selected Failures For each selected failure scenario, the potential contributory factors were examined, taking into account any protective features available. Typically, the factors examined included:  Operator error  Metallurgical fatigue or ageing of materials  Internal or external Corrosion  Loss of process control, e.g. pressure, temperature or flow, etc.  Overfilling of vessels  Introduction of impurities  Fire and/or explosion  Missiles  Flooding Account was taken at this stage of those limited releases, which, although in themselves did not constitute a significant off-site hazard could, under some circumstances, initiate a sequence leading to a larger release, as a knock-on effect. It was noted that the proposed criterion for risk tolerability was used in Egypt by the following organizations: British Gas / British Petroleum / Shell / Total.

This means analyzing the hazard for its probability to actually progress to loss event, as well as likely consequences of this event. There are four steps to calculate risk, which determined as follows: 1- Identify failure frequency (International Data Base) 2- Calculating the frequency against control measures at site by using Event Tree Analysis “ETA”. 3- Identify scenarios probability. 4- Calculated risk to people regarding to the vulnerability of life loses. Basically, risk will be calculated as presented in the following equation: Risk to people (Individual Risk – IR) = Total Risk ( Frequency of fire/explosion) x Occupancy x Vulnerability Where:  Total risk Is the sum of contributions from all hazards exposed to (fire / explosion).  Occupancy Is the proportion of time exposed to work hazards. (Expected that x man the most exposed person to fire/explosion hazards on site. He works 8 hours shift/day)  Vulnerability Is the probability that exposure to the hazard will result in fatality. As shown in tables (5 & 6) – (Page: 33 & 34) the vulnerability of people to heat radiation starting from 12 kW/m2 will lead to fatality accident for 60 sec.

Calculating frequencies needs a very comprehensive calculations which needs a lot of data collecting related to failure of equipment’s and accident reporting with detailed investigation to know the failure frequency rates in order to calculate risks from scenarios. In this study, it decided that to use an International Data Bank for major hazardous incident data. The following table (26) show frequency for each failure can be raised in pressure reduction station operations: EGAS.HSE.QRA.Study.014/Zefta-Egypt.Gas.PRMS.No.011/2018/QRA/MG/MS/WS-DNV-PHAST.7.21/UAN.152,414-PETROSAFE-Draft.Report-Rev.00 Prepared By: Page 93 of 114 PETROSAFE Date: Nov. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Quantitative Risk Assessment “QRA” Study For Zefta Pressure Reduction & Metering Station Table (26) Failure Frequency for Each Scenario Scenario Release Size Gas Release from Small 1”/10” - 16” Pipeline Failure Cause Failure Rate Internal Corrosion 1.19E-05 External Corrosion 3.55E-06 Maintenance Error 2.28E-05 Corrosive Liquid or Gas 4.84E-04 Total 5.22E-04 Gas Release from Medium 4” / 10” - 16” Pipeline Failure Cause Failure Rate Internal Corrosion 2.71E-05 External Corrosion 8.24E-06 Erosion 4.85E-04 Total 5.20E-04 Gas Release from Large 10” / 16” Pipeline Full Rupture Failure Cause Failure Rate Internal Corrosion 5.53E-06 External Corrosion 1.61E-06 Weld Crack 4.34E-06 Earthquake 1.33E-07 Total 1.16E-05 Spotleak Medium (Odorant Tank) As a package Failure Rate Reference: Taylor Associates ApS - 2006 (Hazardous Materials Release and Accident Frequencies for Process Plant - Volume II / Process Unit Release Frequencies - Version 1 Issue 7) 1.25E-05 EGAS.HSE.QRA.Study.014/Zefta-Egypt.Gas.PRMS.No.011/2018/QRA/MG/MS/WS-DNV-PHAST.7.21/UAN.152,414-PETROSAFE-Draft.Report-Rev.00 Prepared By: Page 94 of 114 PETROSAFE Date: Nov. 2018 Egyptian Natural Gas Holding Company “EGAS” Document Title: Quantitative Risk Assessment “QRA” Study For Zefta Pressure Reduction & Metering Station  Event Tree Analysis An event tree is a graphical way of showing the possible outcomes of a hazardous event, such as a failure of equipment or human error. An ETA involves determining the responses of systems and operators to the hazardous event in order to determine all possible alternative outcomes. The result of the ETA is a series of scenarios arising from different sets of failures or errors. These scenarios describe the possible accident outcomes in terms of the sequence of events (successes or failures of safety functions) that follow the initial hazardous event. Event trees shall be used to identify the various escalation paths that can occur in the process. After these escalation paths are identified, the specific combinations of failures that can lead to defined outcomes can then be determined. This allows identification of additional barriers to reduce the likelihood of such escalation. The results of an ETA are the event tree models and the safety system successes or failures that lead to each defined outcome. Accident sequences represents in an event tree represent logical and combinations of events; thus, these sequences can be put into the form of a fault tree model for further qualitative analysis. These results may be used to identify design and procedural weaknesses, and normally to provide recommendations for reducing the likelihood and/or consequences of the analyzed potential accidents. Using ETA requires knowledge of potential initiating events (that is, equipment failures or system upsets that can potentially cause an accident), and knowledge of safety system functions or emergency procedures that potentially mitigate the effects of each initiating event.

In the case of hydrocarbon release, the event tree first branch is typically represents "Early Ignition". These events are represented in the risk analysis as jet fire events. This is because sufficient time is unlikely to elapse before ignition for a gas/air mixture to accumulate and cause either a flash fire or a gas hazard. Subsequent branches for these events represent gas detection, fire detection, inventory isolation (or ESD) or deluge activation. Delayed ignitions are typically represented by the fifth branch event. This is because, in the time taken for an ignition to occur, sufficient time is more likely to elapse for gas detection and inventory isolation. The scenario development shall be performed for the following cases: - Without any control measures - With control measures The event tree analysis outcomes can be classified into three main categories as follows: “Limited Consequence” Indicates that the release has been detected and the inventory source has been isolated automatically. “Controlled Consequence” Indicates that the release has been detected but the source has not been isolated automatically. [Needs human intervention]. “Escalated Consequence” Indicates that the release has not been detected and consequently the source has not been isolated.

Executive Summary Introduction Aiming at connecting the natural gas (NG) to about 15,500 clients in Zefta, Egypt Gas, the local distribution company, will upgrade Zefta network to increase its capacity from 3,000 m 3/h to 10,000m3/h. The objective of the proposed project is to construct a pressure reduction station (PRS) and increase the capacity of the network in order to connect the NG to wider range of clients. This will enable achieving reduction of leakage, reduction of subsidy allocated for the butane gas, and reducing dependence of imported fuel. The ESIA has been prepared by a Joint Venture between Petrosafe (Petroleum Safety & Environmental Services Company) and EcoConServ Environmental Solutions with collaboration and facilitation from EGAS, Egypt Gas HSE, and Engineering Departments. The names of the Petrosafe and EcoConServ experts who have participated in the preparation of the ESIA study are listed in Annex 1 of this report. Project Description The PRS consists of the following components: an inlet unit (isolated catholic system), a liquid separation unit, a filtration unit and equipment for automatically reducing and regulating the pressure (active regulator and monitor regulator). In addition, auxiliary devices include safety valves (Slam Shut), relief valves, an odorizing unit, and ventilation equipment. Utilities existing in a PRS include a control room, a firefighting system (firefighting water tank, firefighting valve), a staff bathroom, a storage area, and entrance room located adjacent to the entrance gate. The PRS for Zefta will be designed to reduce an inlet pressure of 30-70 bar to an outlet pressure of 7 bar at a flow rate of 10,000m3/h. Flow rate can be increased to 20,000 m3/h in the future according to the demand increase. The PRS is located at the Astana-Banha Road (Mit Birah-Zefta) 500 meters south west of Zefta City. Offtake from the national natural gas network is about 18 km away from the PRS location. The HP pipeline connecting the offtake and PRS already exists. Legislative and Regulatory Framework The project will adhere to Egyptian legislations, WB operational policies, and IFC performance standards. Applicable Environmental and Social Legislation in Egypt legislations:  Law 217/1980 for Natural Gas  Law 4/1994 for the environmental protection, amended by Laws 9/2009 and 105/2015. Executive Regulation(ER) No 338/1995 and the amended ER No. 1741/2005, amended with ministerial Decrees No. 1095/2011, 710/2012, 964/2015, and 26/2016  Law 38/1967 for General Cleanliness  Law 93/1962 for Wastewater  Law 117/1983 for Protection of Antiquities II Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019  Traffic Law 66/1973, amended by Law 121/2008 traffic planning  Law 12/2003 on Labor and Workforce Safety World Bank Safeguard Policies Three policies are triggered for the project as a whole: Environmental Assessment (OP/BP 4.01), Physical Cultural Resources (OP/BP 4.11), and Involuntary Resettlement (OP/BP 4.12). However, OP/BP 4.11 and Involuntary Resettlement (OP/BP 4.12) will not be applicable to Zefta PRS project. OP/BP4.11 will not be applicable in Zefta as no archeological sites or sites that bear significant historical or cultural value were identified in the project area of Zefta. In case of any unanticipated archeological discoveries; Annex 6, titled 'Chance Find Procedures,' outlines the set of measures and procedures to be followed. The proposed land for the construction of the PRS was obtained based on willing buyer willing seller approach. Based on the site visits conducted by EGAS and Egypt Gas, there is no encroachment within the PRS land. Supplementary site visits were conducted by the social team. No encroachment were reported and the land purchased for the construction of the PRS was fenced. Therefore, the Involuntary Resettlement (OP/BP 4.12) is not applicable for the proposed project. In addition to the above mentioned safeguards policies, the Directive and Procedure on Access to Information1 will be followed by the Project. World Bank Group General Environmental, Health, and Safety Guidelines 2 & WBG Environmental, Health and Safety Guidelines for Gas Distribution Systems3 The General Environmental, Health, and Safety Guidelines (EHS) are designed to be used together with the relevant Industry Sector EHS Guidelines, which provide guidance to users on EHS issues in specific industry sectors. Gas distribution system – HSE Guideline (provided in Annex 4 from the report) are applicable to the project. Environmental and Social Baseline A. Environmental baseline  Climate o Temperature The average annual temperature is 26.6°C in Zefta. The warmest month of the year is July, with an average temperature of 26.9 °C. January has the lowest average temperature of the year at 13.1°C o Rainfall average annual precipitation in Zefta ranges are between 2mm. to 10.5 mm. o Wind 1 https://policies.worldbank.org/sites/ppf3/PPFDocuments/Forms/DispPage.aspx?docid=3694 2 https://www.ifc.org/wps/wcm/connect/554e8d80488658e4b76af76a6515bb18/Final%2B- %2BGeneral%2BEHS%2BGuidelines.pdf?MOD=AJPERES 3 https://www.ifc.org/wps/wcm/connect/9c6e3d0048855ade8754d76a6515bb18/Final%2B- %2BGas%2BDistribution%2BSystems.pdf?MOD=AJPERES&id=1323162128496 III Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 The wind speed in Zefta ranges are between 43.9Km/h and 59.8Km/h. It is characterized by a calm to moderate breeze. The highest average wind speed occurs during spring, in March and April. o Site-Specific Ambient Air Quality Environmental measurements have been taken at the PRS location as a benchmark to be able to assess the impacts of the PRS construction and operation activities on air quality and noise intensity. 8-hour average measurements were conducted for pollutants of primary concerns, namely carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), total suspended particulates (T.S.P) and particulate matter (PM10). The air quality at the proposed site of the proposed PRS is exhibiting acceptable levels of classic air pollutants in fact the levels are way below the national and international guidelines. o Site specific Noise Measurements Noise level measurements were conducted at the same location (proposed site of the new Pressure reduction station) of the ambient air quality measurements. The duration of the measurements is 8 hours with one hour averaging. The noise measurements were found to be below national and WB guidelines. Annex 5 from the report presents the full Air and Noise measurements at Zefta PRS location.  Geology The Nile Delta basin was affected by the complex evolution and interaction among the African, Eurasian and Arabian plates. Six major structural trends delineate the present Nile Delta and affect the distribution of the Miocene sediments in the Nile Delta; the minor non-structural (NS) Baltim fault trend affects the Zefta area. The strata of hydrological importance, in the Delta area and its fringes, belong essentially to the Quaternary and constitute the main water-bearing formations. The Zefta area belongs to Meet Ghamr formation. It consists mainly of clay and silt including some sand tracks.  Water resources o Surface water Zefta city is located at the Damietta Branch. The PRS is 1.5 km away from the branch. The only existing water body nearby is the main feed canal (as El-Sahil canal) which is used as a main water source for agriculture in Zefta. The canal is approximately 50 m away from the proposed PRS site. The Zefta- Banha road separates the canal from the PRS gate. The canal will not be affected by the proposed project activities during construction or operations due to its separation from the project site by a main road and a railway. o Groundwater There is no site specific data available on the groundwater quality in Zefta. Audebeau (1912) and Zaghloul (1985) gave evidence that the Nile River is the source of the groundwater underlying the valley and Delta. The ground elevation is approximately 5 m above the mean sea level (AMSL) near Tanta city (Saleh, 1980). Tanta city is approximately 23 km away from the project area.  Terrestrial environment Zefta area is not characterized by the presence of endangered species (fauna or flora). The project area is eventually free from any endangered or vulnerable species.  Solid waste management IV Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 The Cleansing department affiliated with the Local unit in Zefta is responsible for waste collection. Few collection bins exist throughout Zefta city. They are used as open transfer systems, existing in residential areas, and later transferred to El-Sadat controlled-landfill located about 140 km from Zefta city. Waste collection services are absent outside the city borders. The accumulated waste in the dumpsite appears as a large plateau. Most of the dump sites are located in an agricultural area close to residential areas.  Physical cultural resources There are no significant physical cultural resources existing near the PRS's project site. Furthermore, no archaeological or antiquities sites were identified within or near the project area. However, in case of any unanticipated archaeological discoveries, 'Chance Find Procedures outlines the set of measures and procedures to be followed in such a case (Annex 6).  Physical structures There are no physical structures near the PRS station in Zefta.  Traffic profile The traffic in Zefta city is of a relatively moderate density. The rush hours can be segregated into two major periods. The first is between 7 - 10 am while the second is between 2 - 4 pm. B. Socio-economic Baseline The PRS is located near Zefta city which is located in the southern eastern part of Gharbeya Governorate. It lies on the Damietta branch across from Meet Ghamr city which lies under the jurisdiction of Al Daqahliyah governorate to the east. There is a small hamlet named Izbet el Gahsh located approximately 700 meter away from the proposed project site. As no information is available on the level of this hamlet, the social baseline will describe the city of Zefta.  Administrative affiliation Zefta city is affiliated to Zefta district which also includes 8 local governmental units (LGUs) and many other towns, villages, and hamlets. The total area of Zefta city is 1,230 km2.  Demographic characteristics The total population of Zefta city is 106,249 persons distributed among 26,562 households according to CAPMAS poverty mapping data of 2013. The total population of Izbet El Gahsh is about 700 people.  Living conditions A household is defined as "Family (and non-family) members who share residence and livelihood and act as one social and economic unit". According to CAPMAS poverty mapping data of 2013, the average family size in Zefta city is 4.  Access to basic services According to CAPMAS poverty mapping data (2013), 99.5% of individuals living in Zefta city use electricity for lighting.

The unemployment rate in Zefta city stands at 12.8%.  Health facilities Zefta city has one central hospital, equipped with an emergency unit. There are a number of private hospitals. Additionally, there is an ambulance station, and a number of urban and rural medical units. There is no assessment of the quality of health services provided in the City of Zefta.  Human activities in the project areas As noted in the unemployment and work status sections, the City of Zefta encompasses a variety of economic activities including agriculture, industry and services. However, there is no study assessing these activities in terms of the level and quality of goods and services produced in the City of Zefta or in terms of job creation. As indicated above; the labor force includes farmers, land owners who cultivate their own lands, government employees, manufacturing workers and car maintenance workers. One of the participants of the focus group discussions stated that the majority of youth work as drivers of popular auto rickshaw (tuk tuk) as it is the only employment vacancy available to young people in the city. Environmental and Social Impacts The environmental and social impact assessment (ESIA) is a process used to identify and evaluate the significance of potential impacts on various environmental and social receptors as a result of planned activities during (construction and operation) phases of the Project. Furthermore, the analysis of environmental and social impacts is important to detail an effective management and monitoring plan, which will minimize negative impacts and maximize positives. A. Potential positive impacts  Positive impacts during construction o Impacts related to employment Provide direct job opportunities to skilled and semi-skilled laborers The construction of the Zefta PRS is expected to result in the creation of job opportunities, both directly and indirectly. Based on similar projects implemented recently by EGAS and the local distribution company, the daily average number of workers during the peak time will be about 16 workers, being 14 laborers and 2 supervisors. The workers can also include drivers, digging staff, technicians and welders. VI Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Create indirect opportunities As part of the construction stage, a lot of indirect benefits are expected to be sensed in the targeted areas due to the need for more supporting services to the workers and contractors who will be working in the various locations. These benefits could include, but are not limited to accommodation, food supply, transport, trade, security, manufacturing, etc.  Positive impacts during operation o Impacts related to employment The operation of the Zefta PRS is expected to result in the creation of job opportunities, both directly and indirectly. The average number of workers during operation of the Zefta PRS will be about 12 workers from the permanent workers of the LDC; 6 technicians, 3 maintenance staff (one engineer and two engineer’s assistance) and 3 security staff. With regards to health and safety, one person will be assigned from the staff of Egypt Gas. Some of the mentioned opportunities are already occupied by Egypt Gas staff while few of the jobs will be need to increase the number of staff (e.g. additional one in health and safety). The current permanent staff also might move to a new site. In this case, new staff will be trained and recruited. B. Potential negative impacts Various impacts were assessed in accordance with the impact assessment methodology. Impacts of no significance are ecological, land acquisition, and visual intrusion, during construction phase. Risks pertaining to child labor, air emissions, soil, ecological, traffic, and labor influx are assessed as of no significance during the operation phase. 5.4 Impacts during Accidental Events (Operation Phase) Regarding to the Quantitative Risk Assessment Study (QRA), which demonstrate on the following hazards: • Gas Release • Fires (Heat Radiation) • Explosion (Overpressure Waves) • Suffocation (Odorant Leak) Referring to the risk calculations determined in Zefta QRA study, the individual risk level to the exposed workers / public (PRS / Off-take Point)) based on the risk tolerability criterion have been identified in Acceptable (Lower Tolerability Limit ) for workers / Off-take public and ALARP (Below the Upper Tolerability Limit) region for public PRS. So there are some points (Study Recommendations) need to be considered to keep the risk tolerability, and this will be describe under item (7.5) (for more details refer to the QRA Study under Annex-10) VII Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 VIII Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Summary of potential negative impacts Potential Impact Significance (Duration, Difficulty to mitigate) Labor Labor Soil Solid, conditions influx pollution Reduction Community Air Ground hazardous and Activity Noise of traffic health and Child labor emissions water wastes and occupational flow safety liquid waste health and safety Potential negative impacts during construction phase Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Mobilization N/A N/A extremely N/A medium low low low medium low low Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Excavation medium low medium medium medium low medium low low low PE Pipe Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, N/A N/A N/A laying medium low medium low medium low low Leakage Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, Temporary, N/A N/A N/A testing medium low low low medium low low Impact Minor- Low to Medium Medium Minor Medium Minor Medium Low Medium Assessment Medium medium Potential negative impacts during operation phase Permanent Permanent Permanent Permanent PRS operation N/A N/A N/A N/A N/A N/A low medium low medium Permanent Permanent Permanent Permanent Repairs N/A N/A N/A N/A N/A N/A low medium low medium Impact No No No No No No Minor Medium Minor Medium Assessment significance significance significance significance significance significance 1 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Analysis of Alternatives  Technology alternatives o Outlet pressure A gas pressure reducing station reduces the pressure in the HP pipeline from 30-70 bar 4 or 7 bar, making it suitable for distribution or use in domestic or industrial applications. Zefta’s PRS will produce 7 bar outlet pressure for the local distribution network (intermediate pressure). The LDC (Egypt gas) choose to produce 7 bar instead of 4 bar due to high consumption rates excepted in Zefta city. It is designed to accommodate future extensions to the distribution network (intermediate pressure) in order to feed other cities and/or villages in the district. o Odorant handling Environmental and safety control considerations and measures are integrated into the selected technology design. For example, in order to reduce emissions from the odorant unit, the odor will be automatically added or by using a plunger pump. Automatic and sophisticated unit management systems ensure safe and easy operation and can encompass complete remote operation of the units.  PRS location alternatives As per national and WB guidelines, PRS siting avoids habitat alteration and seeks to minimize environmental, occupational health and safety, and community health and safety impacts. In 2012, the LDC that was responsible of constructing Zefta PRS was Maya Gas. They were also responsible for purchasing lands needed to construct the PRS. Thereafter, they handed over the construction of the PRS to Egypt Gas. Therefore, it was relatively difficult to define how the process was implmeneted. Given the absence of any information about land acquisition process, the study team conducted meetings with Egypt Gas and EGAS social team for better understanding of the process as Maya Gas was not operating in Zefta any more. In general, EGAS and LDCs follow a set of agreed upon procedures for the process of permanent Land take for the construction of PRSs. The procedure covers cases of land acquisition of State Owned Lands or privately owned Lands on willing Buyer Willing Seller basis. It is the priority of EGAS as an asset holder, to acquire State Owned Lands that are free of any uses (both formal and informal EGAS never resorts to the land expropriation decrees in PRSs selection, particularly because of the flexibility of the PRSs locations. In cases of unavailability or in case the available land is technically unacceptable, private land is usually used as a second a resort. Land alternatives are examined and the optimum technical and socio-economic scenario of land is selected. Consultation activities are conducted through the project cycle with the individuals who offer to sell their land, dissemination of project information at the early stages of the project during the frameworks preparation followed by consultation activities with the Project affected persons (e.g. cases of farmers whose land are temporary affected from the high pressure pipelines passing their land) and during land acquisition with land owners Environmental and Social Management & Monitoring Plan The objective of the Environmental and Social Management and Monitoring Plan (ESMMP) is to outline actions for minimizing or eliminating potential negative impacts and for monitoring ii Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 the application and performance of mitigation measures. The ESMMP identifies roles and responsibilities for different stakeholders for implementation and monitoring of mitigations. This section also presents an assessment of the institutional capacity and institutional responsibilities for implementing the ESMMP. Full ESMMP is presented in section 7 of this report. Stakeholder Engagement and Public Consultation The consultation activities were conducted in full compliance with the following legislations: - WB policies and directives related to disclosure and public consultation, namely, o Directive and Procedure on Access to Information o World Bank Operational Policy (OP 4.01) - Egyptian regulations related to the public consultation o The environmental law No 4/1994 modified by Law 9/2009 modified with ministerial decrees no. 1095/2011 and no. 710/2012 For the purpose of the PRS-related ESIA, qualitative information and data were collected through identifying Project Affected Peoples (PAPs) residing in the areas surrounding the PRS station and recognize their views and concerns about the project. The aim of this endeavor is to ensure a well-integrated and inclusive public review of the project. Key groups of relevance include: ordinary citizens, community leaderships, officials and government representatives, potential, local Non-Governmental Organizations (NGOs) and Community Development Associations (CDAs). In this regard, key groups of relevance in Zefta were approached and consulted using various tools (i.e. in-depth interviews, focus group, meetings, Panel meeting and public consultation sessions). Stakeholder engagement and public consultation activities encompassed a gender aspect that women's views and concerns were taken into account and documented well.  Consultation methodology and activities The consultation process was dynamic and evolving which adapted with the nature and expectations of the host community. In order to establish a more profound understanding of the local communities' perceptions and perspectives of the project, stakeholders' engagement and public consultation activities included a broad base of community members and governmental entities. The first step was to collect the responses and feedbacks of the local communities through conducting Focus Group Discussions (FGDs), structured questionnaires, panel meeting, and public consultation sessions. The second step was to analyze these qualitative data in order to reach a conclusion regarding the general stance and attitudes of the local communities towards the project. Various NGOs participated actively in the preparation of the FGDs and provided data collectors to assist the team in collecting the data.  Summary of discussions With regard to the PRS, stakeholders' engagement and public consultation activities were conducted in order to ensure that the views and concerns of the local communities are integrated and guarantee that they are taken into account by the different parties in charge of iii Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 implementing the project. The views and concerns of local communities are an integral part of the project and to be thoroughly taken into account throughout the different phases of the project. The field research team commissioned by EcoConServ engaged in a number of social activities. These activities include focus group discussions with potential beneficiaries; in-depth discussions with government officials, representatives of civil society, and community leaders. A panel meeting was held at Zefta's LGU headquarters where the public officials of Zefta's LGU stressed on expediting the implementation of the project in their city. Throughout the discussions interviewees were asked about three main points: o The safety of 70 bar pipelines. o The compensation mechanisms for damages resulting from constructions o Safety procedures during operations It was notable that the reactions and attitudes of the local communities towards the project are in favor of the project. The field research team noted a strong public support and eagerness towards the project. Beside some legitimate concerns expressed by the public, the field research team recorded the general view that the NG is a far better substitute for the type of fuel currently in use and that it carries many economic benefits for Zefta. ESIA disclosure As soon as the site-specific ESIA is approved by the World Bank and EEAA, a final report will be published on the WB, EGAS, and Egypt Gas websites. An executive summary in Arabic will be published on EGAS and Egypt Gas websites. A copy of the ESIA report in English and a Summary in Arabic will be made available in the customer service office. Additionally, an Arabic summary will be made available in the contracting offices. An A3 poster will be installed in the contracting office informing about the results of the ESIA and the website link for the full ESIA study. iv Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 1 Introduction 1.1 Preamble Aiming at installing the NG to about 15,500 clients in Zefta, the Local Distribution Company Egypt Gas will upgrade Zefta network to increase its capacity from 3,000 m3/h (to a capacity of 10,000m3/h). The objective of the proposed project is to construct Pressure Reduction Station (PRS) and increase the capacity of the network in order to install the NG to wider segment of clients. This will enable achieving reduction of leakage; reduction of subsidy allocated for the butane gas and reducing dependence of imported fuel. 1.2 Environmental and Social Impact Assessment (ESIA) The World Bank’s Environmental and Social Safeguard policies require an Environmental & Social Impact Assessment (ESIA) be conducted for the proposed pressure reduction station (PRS). This ESIA has been prepared based on the Terms of Reference prepared by EGAS and cleared by the World Bank. The ESIA has been completed by a joint venture between Petrosafe (Petroleum Safety & Environmental Services Company) and EcoConServ Environmental Solutions. The ESIA is undertaken to assess and propose mitigation measures for environmental and social impacts of the PRS. Off-takes from the national network and high pressure (HP) pipeline 70-bar system already exist; and have been fully addressed in the Due-Diligence report, which is a standalone document. The objectives of the ESIA include: - Describing project components and activities of relevance to the environmental and social impacts assessments - Identifying and addressing relevant national and international legal requirements and guidelines - Describing baseline environmental and social conditions - Presenting project alternatives and the no project alternative - Assessing potential site-specific environmental and social impacts of the project - Developing environmental & social management and monitoring plans in compliance with the relevant environmental laws - Documenting and addressing environmental and social concerns raised by stakeholders and the Public in consultation events and activities This ESIA is site specific for PRS (with a capacity of 10,000 m3/h, and can be increased to 20,000 m3/h. in the future). Off-take from the national Gird and HP pipeline about (18 Km) already exists and will not be addressed in this ESIA. The local distribution company responsible for the construction and operation of Zefta PRS is Egypt Gas )‫(غاز مصر‬. 1.3 Contributors The ESIA has been prepared by a Joint Venture between Petrosafe (Petroleum Safety & Environmental Services Company) and EcoConServ Environmental Solutions with collaboration and facilitation from EGAS, Egypt Gas HSE and Engineering Departments. The names of the Petrosafe and EcoConServ experts who have participated in the preparation of the ESIA study are listed in Annex 1 of this report. Page 1 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 2 Project Description 2.1 Background Natural Gas (NG) is processed and injected into the high pressure lines of the national Grid (70 Bar) for transmission. Upon branching off from the main lines to regional distribution networks, the pressure of the NG is lowered to 7 Bar at the PRS. An odorant is added to the NG at PRSs feeding distribution networks to residential areas4 in order to facilitate detection in the event of NG leakage. In addition to excavation and pipe lying, key activities of the construction phase also include installation of mechanical equipment. The diagram below presents the components of a city’s distribution network. The component covered in this ESIA is lined in red. Other components are addressed in a separate ESMP: Transmission Lines (main Line) Receive from processing facilities at 70 Bar Feed Pressure Reducing Stations (PRS) Pressure Reduction Stations (PRSs) Typically located at the borders Odorant addition (facilitate of serviced areas Reduce pressure to 7 Bar detection) Local Distribution Network: Distribution mains 7 Bar (intermediate pressure) Steel or polyethylene (PE) pipes Local Distribution Network: City gate regulators 0.1-2 Bar medium pressure 0.1 Bar low pressure mains PE pipes Local Distribution Network: Connection lines Lateral connections from mains Output pressure at home Enter households via meters, to residential units (steel pipes) regulators is 22.5 mBar connects to appliances Figure ‎ 2-1: General components of the city’s distribution network 4 Because natural gas is odorless, odorants facilitate leak detection for inhabitants of residential areas. Page 2 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 2.2 Project Work Packages 2.2.1 Pressure Reduction Station (PRS) A PRS consists of the following components: an inlet unit (isolated cathodic system), a liquid separation unit, a filtration unit and equipment for automatically reducing and regulating the pressure (active regulator and monitor regulator). In addition, auxiliary devices include safety valves (Slam Shut), relief valves, an odorizing unit and ventilation equipment. Utilities existing in a PRS include a control room, a firefighting system (firefighting water tank, firefighting valve), a staff bathroom, and a storage area and entrance room located adjacent to the entrance gate. The PRS for Zefta will be designed to reduce an inlet pressure of 30-70 bar to an outlet pressure of 7 bar at a flow rate of 10,000m3/h. Flow rate can be increased to 20,000 m3/h in the future according to demand increase. 2.3 Project Location The PRS is located at the Astana-Banha Road (Mit Birah-Zefta) 500 m south west of Zefta City as shown in the figures below. Off-take from the national natural gas grid is about 18 km away from the PRS location. The HP pipeline connecting the Off-take and PRS already exists. Figure ‎ 2-2: PRS location Page 3 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Figure ‎ 2-3: The road in front of the PRS Figure ‎ 2-4: The route in front of the PRS Page 4 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 2.4 Associated facility (Off-take and HP pipeline) As previously mentioned, the off-take from the national gird and the HP pipeline (70 bar system) already exists. A due diligence study has been prepared for clearance and the LP Network is addressed in a separate ESMP The off-take is the point on the HP national grid pipeline where a branch of the pipeline is constructed to connect a new PRS to the national grid. At the off-take location, valve rooms/valve ditching is constructed so as to control the flow of the natural gas through the pipeline (branch). These valves work like gateways for the Zefta area. The off-take is located at Meit Abo Sheikha–Hanoun road, south of Tukh Tambasha Village. The Off-take location is remotely located, away from any residential areas. The nearest village to the north is Tukh Tambasha, approximately 700 m away from the off-take site. The area surrounding the off-take is characterized as agricultural land. Figure ‎ 2-5: Zefta PRS location Page 5 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Figure ‎ 2-6: The off-take 2.5 Project Execution Methodology 2.5.1 General survey - Identifying availability of utilities in the area and their conditions (electricity, water, telephone lines, and sanitary pipelines) through data and maps from the relevant authorities. - Identifying the location of the nearest national grid pipelines, gas networks and off-take. - Identifying the location of the new PRS location. 2.5.2 Design and material take-off (MTO) including procurement Once the final location of project components is finalized, a final design of the PRS is utilized to estimate the materials and equipment needed to implement the project. Procurement of the materials includes local and international components. The main international purchases may include critical components and PRSs, regulators, and metering stations. 2.5.3 Construction works of PRS 2.5.3.1 Pressure Reduction Station Area Minimizing the possible negative impacts on the project’s surroundings, the safety of neighboring areas from possible gas release accidents, and noise associated with the operation of reducers. The PRS will be surrounded by a wall for safety and security purposes (including reducing noise impacts of the PRS on the surrounding receptors). Currently, there are scattered buildings in the agricultural land surrounding the PRS. The closest buildings are around 90-100 m north east of the proposed PRS location, and are separated by the Zefta –Banaha road Page 6 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 (Figure 2-55). In the event that buildings are constructed in the area surrounding the PRS, the Institute of Gas Engineers Safety Recommendations requires the following buffer zones: - PRS should have free areas from each side to allow for emergency vehicle access. The nearest building is far 90 m to the east of the PRS fence. Zefta PRS is to be located in a low-population-density area on a plot of land measuring 40m x 70m. The PRS is to be accessible by an existing road (Zefta – Banha Road) to ensure quick response in the event of repairs and/or emergencies. The land is owned by EGAS since before the beginning of the project.. The site is located in a large area of agricultural land with no existing facilities. Annex 2 from the report provides official hand over of the lands to Zefta PRS . . Figure ‎ 2-7: Site surrounding Zefta PRS 2.5.3.2 Pressure Reduction Station Civil Works A 9-months construction schedule is planned for Zefta's PRS, with site preparation expected to commence in the first half of2019 The main construction activities will include: - Site preparation, acceptance and placement of major fabricated equipment items, construction of buildings, testing and commissioning. - Initial construction activities involve clearing and grading of the site, sediment fences and silt traps will be installed, as necessary, to control erosion and sediment transport during site preparation activities. Page 7 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 - Following site preparation, individual excavations will be made for fire-fighting tanks, domestic wastewater trenches, pipe racks, and a 6-m high wall (of cement) around the PRS. - Concrete foundations for buildings and footings for mechanical equipment will be laid down; - Facility piping (inlet, outlet and 4 inch firefighting line) both above and below ground, are installed. - Construction of a 100m2 control room with a bathroom, an electrical unit’s room, and a security room adjacent to the PRS. 2.5.3.3 Pressure Reduction Station Mechanical Works Zefta PRS comprises of two pressure streams; the upstream (inlet) high pressure ranging from 30 to 70 bar and the downstream (outlet) low pressure 7 bar. The PRS design is in accordance with the Institute of Gas Engineers/Safety Recommendations IGE/SR/9, 10, 16, 18, 22, 23, 24, 25; Institute of Gas Engineers/ Transmission Distribution IGE/TD/13; and National Fire Protection Association NFPA 15. Figure ‎ 2-8: Typical example of the planned PRS Following the construction of the foundation and fences, construction will continue with the installation of mechanical components. Mechanical components include the following: - Inlet ball valve - Solid filtration - Liquid filtration Page 8 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 - Water bath heater - Reduction regulator - Active regulator - Monitor regulator - Slam shut /Safety valve - Relief valve - Measuring unit - Odorizing unit - Outlet unit Figure ‎ 2-9: Zefta Pressure Reduction Station Layout Page 9 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 2.5.3.4 Testing Following mechanical completion, testing of the facility components will be performed in accordance with applicable standards. 2.6 Operation phase 2.6.1 Operation of the PRS Operation of the PRS involves operation of the various components outlined in the construction phase. Risks associated with those activities are further addressed separately in a Quantitative Risk Assessment (QRA) (Refer to annex 10 quantitative risk assessment study) Inlet ball Valves The inlet valve includes an insulation joint to completely isolate the PRS inlet from the cathodic system applied to the feeding steel. Insulation joints isolate the PRS as measure of protection during strikes and current. 2.6.1.1 Filtration unit The filtration unit consists of two main stages, a liquid filtration stage and a solid filtration stage. The aim of the filtration unit is to remove dust, rust, solid contaminants and liquid traces before entering into the reduction stage. Two filters and two separators are installed in parallel; each filter-separator operates with the full capacity of the PRS to separate condensates and liquid traces. The solid filtration unit is designed to separate particulate matter larger than 5 microns. Filter-separator lines are equipped with safety devices such as differential pressure gauges, relief valves, liquid indicators, etc. 2.6.1.2 Heating unit/Water Bath Heater This unit ensures that inlet gas to the reduction unit enters with a suitable temperature (the temperature of gas flow entering the station should be 15oC; and to avoid the formation of natural gas water hydrates in the line downstream of the choke or regulator (due to Joule Thompson effect). Temperature increases by heat exchange between gas pipeline pass through the heating unit filled with hot water. The unit was designed to be heated to 60 oC; while the heating temperatures for the outlet flow gas ranges between 35oC and 45oC. The heating unit comprises of the following components: - Heater body/shell - Process gas inlet/outlet - Water Expansion tank - Burner , Gas Train & BMS Panel - Removable Fire tube - Exhaust stack - Heating medium( Water Bath) The PRS will be equipped with two heaters in parallel (one of them being on standby in case of emergencies). 2.6.1.3 Reduction Each PRS includes two reduction lines in parallel (one of them being on standby in case of emergencies). The lines are equipped with safety gauges, indicators and transmitters to maintain safe operating conditions. According to the IGEM standards, the reduction unit should be installed in a well-ventilated closed area or, alternatively, in an open protected area. Page 10 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 2.6.1.4 Active and Monitor Regulator The active regulator controls the outlet pressure while the monitor regulator assumes control in the event of failure of the active device. 2.6.1.5 Slam Shut Valve The purpose of slam shut valve is to totally, automatically and rapidly cut off gas flow when the outlet pressure exceeds or drops below the setting pressure. The valve has to be installed to protect the system. The safety valve has to be sized for the maximum gas flow with the highest pressure that could be provided to the pressure reducing valve. 2.6.1.6 Measuring Unit After adjusting the outlet pressure, gas flow and cumulative consumption are then measured to monitor NG consumption from the PRS and to adjust the dosing of the odorant indicated in the subsection below. 2.6.1.7 Odorizing Unit Natural gas is generally odorless. The objective of odorizing is to enable the detection of gas leaks at low concentration, before gas concentrations become hazardous. The odorant is composed of Tertiobutylmercaptin (80%) and Methylsulphide (20%). The normal dosing rate of the odorant is 10-20mg/cm3. The odorant system consists of a stainless steel storage tank, which receives the odorant from 200-liter drums, injection pumps, and associated safety devices. 2.6.1.8 Outlet unit The outlet unit includes an outlet valve gauge, temperature indicators, pressure and temperature transmitters and non-return valves. The outlet pipes are also, like inlet pipes, isolated from the cathodic protection by an isolating joint. 2.6.1.9 Hotline A 24 hours /7days a week Hotline (129) is available for customers and the public to request repairs or assistance. This line is also used in case of emergencies to report leaks, damage, emergencies, and/or incidents related to gas connections, components, infrastructure, and activities (inside or outside households). 2.7 Resources Consumption 2.7.1 During Construction phase 2.7.1.1 Water Water is mainly used during the construction phase in concrete preparation, hydrostatic testing, and domestic uses by the workers and engineers. Water for construction and hydrostatic testing is sourced from trucks. Bottled water will be used for drinking purposes. The expected amount of water to be used during the construction phase of this project is: - Domestic uses by the workers and engineers: 5 m3/day - Construction activities: 250 m3 2.7.1.2 Fuel Diesel fuel will be mainly used for: - Diesel generators to supply electricity to the various construction activities including welding. Page 11 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 - Trucks and excavators. The expected amount of diesel fuel to be used in the construction phase of the PRS is around 60 liters per day. The fuel will be delivered to the construction site via trucks when needed. 2.7.2 During operation phase 2.7.2.1 Water Water is mainly used during the operation phase in the firefighting storage tank as well as for domestic use by workers in the PRS and drinking water. The water source will be determined during the construction phase: either the PRS will be connected to the public water network or water will be delivered by trucks. 2.7.2.2 Electricity Electricity consumption during the operation phase is expected to be minimal which will be mainly consumed at the control room. The PRS will be connected to the national gird network existing in the area. 2.8 Waste Generation All solid waste generated during the construction phase will be managed and disposed in accordance with applicable regulations and established best management practices. All generated wastes will be reused and/or recycled to the maximum extent possible. 2.8.1 During construction 2.8.1.1 Solid waste Solid waste generated during the construction phase will comprise of domestic waste, construction waste and some hazardous wastes from construction activities. The hazardous wastes generated from site are of small quantities (mainly empty odorant containers and empty paint containers). These wastes are stored on site and transported to the temporary storage facilities of the LDC where all hazardous wastes are transported to the licensed hazardous waste facilities in Nassreya in Alexandria Governorate The waste is expected to include the following waste streams: Table ‎ 2-1: Waste types and how they will be managed Hazardous/Non- Waste type Treatment and Disposition hazardous Cement and Concrete Non-hazardous Dispose to an approved waste disposal Wastes (Including Cement facility.(El sadat land field –away about Contaminated Soil) 120 Km from the site) Domestic Waste (food waste, packing…) Wood – Scrap Non-hazardous Temporarily stored in isolated area on- Tires site, then transported to Abu Rawash storage site (Egypt Gas facility) to be sold Cardboards Page 12 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS -Final Report April 2019 Hazardous/Non- Waste type Treatment and Disposition hazardous Containers as scrap.

Six major structural trends delineate the present Nile Delta and affect the distribution of the Miocene sediments in the Nile Delta; the minor NS Baltim fault trend affects the Zefta area. The strata of hydrological importance, in the Delta area and its fringes, belong essentially to the Quaternary and constitute the main water-bearing formations. Page 19 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 The Zefta area belongs to the Mit Ghamr formation. It consists mainly of clay and silt including some sand tracks. Figure ‎ 4-1: Geological Map of Nile delta include project area Source: H.H. Elewa, 2010 4.2.3 Water resources 4.2.3.1 Surface water Zefta city is located at the Damietta Branch. The PRS is 1.5 km away from the branch. The only existing water body nearby is the main feed canal (AsSahil), which is used as a main water source for agriculture in Zefta. The canal is approximately 50 m away from the proposed PRS site. The Zefta- Banha road separates the canal from the PRS gate. The canal will not be affected by the proposed project activities during construction or operations, due to its separation from the project site by a main road between and a railway. Page 20 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 Figure ‎ 4-1: As Sahil canal 4.2.3.2 Groundwater There is no site specific data available on the groundwater quality in Zefta. Audebeau (1912) and Zaghloul (1985) gave evidence that the Nile River is the source of the groundwater underlying the valley and Delta. The ground elevation is approximately 5 m above the mean sea level (AMSL) near Tanta City (Saleh, 1980). Tanta city is approximately 23km away from the project area. 4.2.4 Terrestrial Environment Zefta current land use for the location of the PRS is for agricultural purposes. Therefore it is a modified habitat and has no ecological importance. Additionally, the area is not characterized by the presence of endangered species (fauna or flora). The project area is eventually free from any endangered or vulnerable species. 4.2.5 Solid Waste Management The Cleansing department affiliated with the Local unit in Zefta is responsible for waste collection. Few collection bins exist throughout Zefta city. They are used as open transfer systems, existing in residential areas; and later transferred to El-Sadat controlled-landfill, located Page 21 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 about 140 km from Zefta city. Waste collection services are absent outside the city borders. The accumulated waste in the dumpsite appears as a large plateau. Most of the dumpsites are located in an agricultural area close to residential areas. 4.2.6 Physical cultural resources There are no significant physical cultural resources existing near the PRS's project site. Furthermore, No archaeological or antiquities sites were identified within or near the project area. However, in case of any unanticipated archeological discoveries; 'Chance Find Procedures, outlines the set of measures and procedures to be followed in such a case (Annex 6). 4.2.7 Physical structures There are no physical structures near the PRS station in Zefta. 4.2.8 Traffic profile The traffic in Zefta city is of a relatively moderate density. The rush hours can be segregated into two major periods. The first is between 7 - 10 am, while the second is between 2 - 4 pm. Figure ‎ 4-2: Zefta city main streets Page 22 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 There are many types of vehicles moving inside and outside Zefta city Such as private cars, microbuses and Rickshaws (Tuk Tuk). The main streets defined in this study were Yosef El Gendy St. El Geish st. and El Tahrir st. The traffic is relatively of high density in the main streets, particularly, as many of them are of commercial nature. 4.3 Socio-economic Baseline The PRS is located in the vicinity of Zefta city which is located in the southern eastern part of Gharbeya Governorate. It lies on the Damietta branch across from Mit Ghamr city, which lies under the jurisdiction of Al Daqahliyah governorate, to the east. There is a small hamlet named Izbet el Gahsh located approximately 700 meter away from the proposed project site. As no information is available on the level of this hamlet, the social baseline will describe the city of Zefta. Figure ‎ 4-2: PRS location 4.3.1 Administrative affiliation Zefta city is affiliated to Markaz Zefta which also includes 8 Local Governmental Units (LGUs) and many other towns, villages and hamlets. The total area of the City of Zefta is 1,230 km2. 4.3.2 Urbanization trends Zefta city is of a varied character. It encompasses agrarian lands as well as urban spaces. The condition of the urbanized spaces, which encompass the majority of residents, is haphazard, and Page 23 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 lacks any sort of architectural identity. According to the head of the Projects' department in the municipality, the city center of Zefta contains many illegal and broken down buildings which puts an obstacle to NG connections . According to CAPMAS poverty mapping data of 2013, the percentage of individuals living in apartments is 90.64%, while those living in rural houses represent 0.62%. The remaining percentage lives in one room or two inside an apartment. 4.3.3 Demographic characteristics 4.3.3.1 Total Population The total population of the City of Zefta is 106,249 citizens in 26,562 households, according to CAPMAS poverty mapping data of 2013.

Below five years old mortality rate is 15.90 per 1000 children. Population natural growth rate is 20.20 per 1000 persons. 4.3.4 Living Conditions 4.3.4.1 Household size and density A household is defined as “Family (and non-family) members who share residence and livelihood, and operate as one social and economic unit”. The average family size in the City of Zefta is 4, According to CAPMAS poverty mapping data of 2013. 4.3.4.2 Dwelling characteristics As mentioned above, the majority of the population of the City of Zefta lives in apartment buildings. The conditions and characteristics of urban houses are in compliance with the bases and preconditions for connecting NG. Concrete and red bricks were used in the construction of the walls and ceilings. The finishes and facades of all buildings are of very poor quality and the entire city lacks any sort of architectural identity. Most of the buildings are legal, however, the research team documented some neighborhoods were illegally built on agrarian lands. In the same respect, the city center contains some unplanned and illegal areas and buildings, as noted by the head of the Projects' department in the urbanization trends section. Regarding the conditions and characteristics of the streets, the average width of main streets range between 1 to 2 lanes wide and side streets are 1 lane wide. All streets that were documented by the research team are paved out, though the condition of the asphalt varies between modest and poor. The following figures illustrate typical streets and alleyways in the City of Zefta.

The electricity grid covers 1,352.94 subscribers in the entire governorate of Gharbya, according to 'Governorates' Description by Information 2010' 4.3.5.2 Access to potable water and sanitary system The city of Zefta is located on the western bank of the Damietta branch. CAPMAS poverty mapping 2013 figures show that accessibility to the portable water network is high at 98.11%, and 96.21% of individuals have tap water inside their homes. On the other hand, accessibility to the public sanitation network stands at 53.57% of individuals, according to CAPMAS poverty mapping 2013. The representative of the department of urban planning referred to the fact that the construction of the sewage station is incomplete. It is noteworthy to mention that the condition of public services in the City of Zefta is dire, according to the information center representative interviewed by the field research team. 4.3.6 Human development profile 4.3.6.1 Education According to CAPMAS Poverty Mapping data of 2013, 15% of individuals have completed their basic education consists of primary and preparatory stages, while only 18.1% have university degrees. A substantial 94.6% of individuals, between 6 to 18 years old, are enrolled at schools; while the percentage of drop-outs stands at 2.8%. In the same vein, 96.33% of females, between the ages of 6 to 18 years old, are enrolled at schools; while the percentage of female drop-outs stands at 1.77%. The percentage of females with university degrees is 14.7%. The illiteracy rate in the City of Zefta is 26.7%. The illiteracy rate among females is 31%. Page 25 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 4.3.6.2 Unemployment and Work Status According to CAPMAS poverty mapping 2013, the percentage of manpower which joined the labor force at the age of 15 years old and above is 45.32%. Manpower, at the age of 24 years old and above, is 52.4%. The percentage of agriculture workers from total employed persons is 6.8%. The unemployment rate in the City of Zefta stands at 12.8%. The following table illustrates the distribution of manpower among different sectors: Table ‎ 4-6: Employment in the City of Zefta Self- Government Private Permanent Temporary Wage Unpaid employed /public sector jobs jobs workers worker sector 8.42% 31.44% 46.7% 79.8% 21% 71.7% 0.45% Source: CAPMAS poverty mapping, 2013 In the same respect, female employment figures show that the female unemployment rate is 24%. The percentage of female workers, who joined the labor force at the age of 15 years old and above, is 19.26%. The following table displays more figures related to the type of work taken up by females in the City of Zefta. The formal Statistics obtained from the Poverty Mapping Data 2013 regarding manpower reflected that the age of starting work is 15 years old.9 Both the Child Law and the Labor Law state that children shall not be employed before they complete 14 calendar years old, nor shall they be provided with training before they reach 12 calendar years old; however children between 12 and 14 years old are permitted to work as trainees. Furthermore, the governor concerned in each governorate, in agreement with the Minister of Education may permit the employment of minors aged 12-14 years in seasonal work which is not harmful to their health and growth, and which does not conflict with regular school attendance. Consequently, there is always a high probability to detect child labor in most of the projects implemented in Egypt. In the project areas where agriculture work and sales activities are in place, there is a big number of underage laborers were noticed. As a conclusion, there is a high risk that the contractors might employ young people below 18 years old. Therefore rigid restrictions to employ this category must be added to the contractor obligations.

There are certain critical obligations to recruit children below 15 years old. Article 98-103 of Labor law put limitations related to age, type of occupation, hazards work…etc Page 26 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 According to focus group discussions and interviews with government officials, the labor force includes farmers, land owners who cultivate their own lands, government employees, manufacturing workers and car maintenance workers. Economic activities of the City of Zefta also include commercial activities, brick kilns and carriage manufacturing. According to 'Governorates' Description by Information 2010,' Zefta produces 80% of Egypt's linen and barley production. It also hosts the spinning, weaving and dying industries. 4.3.7 Health Facilities The City of Zefta has one central hospital, equipped with an emergency unit. There are a number of private hospitals. Additionally, there is an ambulance station, and a number of urban and rural medical units. There is no assessment of the quality of health services provided in the City of Zefta. 4.3.8 Poverty index According to poverty mapping developed by CAPMAS in 2013, the number of poor people in the City of Zefta is 4,919 individuals, representing 4.63%. The Gini Coefficient, which indicates income inequality, stands at a critical 0.22. The percentage of female-headed households is 14.6%. According to focus group discussions and consultations with public officials, residents of the City of Zefta are burdened with the pressure of expensive bills, especially electricity bills. According to CAPMAS poverty mapping of 2013, the annually per capita consumption rate in the City of Zefta is 8,198.22. EGP And based on focus group discussions, the average monthly expenses is estimated between 2,000 and 5,000 pounds. 4.3.9 Human activities in the project areas As noted in the unemployment and work status sections, the City of Zefta encompasses a variety of economic activities including agriculture, industry and services. However, there is no study assessing these activities in terms of the level and quality of goods and services produced in the City of Zefta or in terms of job creation. As indicated above; the labor force includes farmers, land owners who cultivate their own lands, government employees, manufacturing workers and car maintenance workers. One of the participants of the focus group discussions stated that the majority of youth work as drivers on popular three-wheeled Tuk Tuk, for it is the only employment vacancy available to young people in the city. Page 27 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 5 Environmental and Social Impacts The environmental and social impact assessment (ESIA) is a process used to identify and evaluate the significance of potential impacts on various environmental and social receptors as a result of planned activities during different phases (construction and operation) of a project. Furthermore, the analysis of environmental and social impacts is important to detail an effective management and monitoring plan which will minimize negative impacts and maximize positives. The evaluation of the potential impacts on various receptors is based on a significance ranking process described in the following subsection. 5.1 Impact Assessment Methodology The impact assessment methodology adopted for this ESIA is a semi-quantitative “cause-effect” matrix modified from Leopold and Buroz´s Relevant Integrated Criteria. The Leopold matrix is two-dimensional, where the stages of the project (activities) are assessed in relation to the existing environmental characteristics and conditions that may be affected during the execution of those actions. The impact of each activity on each receptor was assessed according to magnitude on a scale of -10 to 10, where negative values indicate a negative influence on the receptor, and importance on a scale of 0 to 10, which encompasses the probability of occurrence, frequency of the impact etc. The numbering system is used as a relative measure, where more negative numbers correspond to impacts having a higher negative magnitude. Susceptible receptors and corresponding activity are deduced if magnitude and importance are of minor severity. Then the importance of each impact by activity is determined based on the Buroz relevant integrated criteria. The importance of each impact by activity is assessed by assigning a score for intensity, extension, momentum, persistence, reversibility, recoverability, synergy, accumulation, effect and frequency of the impact. The importance, I, is determined according to I = ± (3IN + 2EX + MO + PE + RV + SI + AC + EF + PR + MC). Details including definitions of each assessment criterion and corresponding score scale for the Buroz Relevant Integrated Criteria are presented in Annex 7. For both methods, the severity of the impact is defined as either irrelevant, of no significance minor, medium, or major according to each method’s scoring scale. Detailed tables with numbers and corresponding coloring are provided in Annex 7. Results from both methods are summarized and presented according to the following scheme: Impact rating Color None or irrelevant (no impact)/ of no significance; Minor severity (minimal impact; restricted to the work site and immediate surroundings) Medium severity (larger scale impacts: local or regional; appropriate mitigation measures readily available); Major severity (Severe/long-term local/regional/global impacts; for negative impacts mitigation significant). Page 28 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 5.2 Potential positive impacts 5.2.1 Positive impacts during construction 5.2.1.1 Impacts related to employment The project will result in positive impacts through the provision of job opportunities. Provide direct job opportunities to skilled and semi-skilled laborers The construction of the Zefta PRS and hotspot is expected to result in the creation of job opportunities, both directly and indirectly. Based on similar projects implemented recently by EGAS and the local distribution company, the daily average number of workers during the peak time will be about 16 workers, being 14 laborers and 2 supervisors. The workers can also include drivers, digging staff, technicians and welders. Create indirect opportunities As part of the construction stage, a lot of indirect benefits are expected to be sensed in the targeted areas due to the need for more supporting services to the workers and contractors who will be working in the various locations. These benefits could include, but are not limited to accommodation, food supply, transport, trade, security, manufacturing, etc. 5.2.2 Positive impacts during operation 5.2.2.1 Impacts related to employment The project will result in positive impacts through the provision of job opportunities. Provide direct job opportunities to skilled and semi-skilled laborers The operation of the Zefta PRS is expected to result in the creation of job opportunities, both directly and indirectly. The average number of workers during operation of the Zefta PRS will be about 12 workers from the permanent workers of the LDC; 6 technicians, 3 maintenance staff (one engineer and two engineer’s assistance) and 3 security staff. With regards to health and safety, one person will be assigned from the staff of Egypt Gas. Some of the mentioned opportunities are already occupied by Egypt Gas staff while few of the jobs will be need to host additional staff (e.g. additional one in health and safety). The current permanent staff also might move to a new site. In this case, new staff will be trained and recruited. 5.3 Potential negative impacts Various impacts were assessed in accordance to the impact assessment methodology. 5.3.1 Negative impacts during construction 5.3.1.1 Impact on soil The excavation activities will result in the disturbance of soil characteristics and cause soil erosion. This will be more pronounced where excavation, as soil compaction may occur due to Page 29 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 heavy machinery. In addition, potential soil contamination may occur as a result of oil spills and leaks. Therefore the impact on soil considered medium. 5.3.1.2 Air Emission PRS construction will include several activities such as excavation, land clearing, concrete foundations, transportation of construction material and equipment, burial of cables and pipes, etc. These activities in consequence are expected to emit air pollutants to the ambient air. The duration of this impact is expected to be short. The following air pollutants are foreseeable for most of the construction activities: - Fugitive dust emissions ( PM10, PM2.5) - Exhaust of vehicles or equipment such as temporary generators, trucks, trolley, etc. Dust emissions will slightly negatively impact ambient air quality, particularly during the initial phases of construction. An isolating radius will be created around any residential areas. Therefore, it is expected that the dust impact will moderately impact the surrounding area (agriculture land). Soil characteristic at PRS site is mainly hard soil. Emissions of CO2, CO and PM will result from the operation of construction machinery and road vehicles during construction of the PRS. - Air pollutants emitted from construction machinery are generally temporary (during the working activities). - The intensity of work activities and the number of vehicles traveling onsite would be relatively low for all tasks. - The emissions will be mostly limited to the construction phase and therefore are temporary. Therefore the impact is assessed as medium 5.3.1.3 Noise emissions Construction of the PRS will require using various construction equipment, vehicles, etc. in addition to the other activities that generate noise. These tools signify potential major sources of noise emissions that will have an impact on sensitive receptors10 (such hospitals, schools, protectorates, etc.). The potential groups who are susceptible to the construction noise during the construction of the Zefta PRS are the following: - Onsite Workers - Neighbor’s farmer It is worth mentioning that the proposed PRS site is located at the Banha-Zefta road, where the noise baseline is already high but does not exceed the national and international standards. Construction activities may increase the already existing baseline ambient noise. However, increased noise emissions are anticipated to be for a short duration of time. Regarding the construction of the Zefta PRS, it is expected that the generated noise will mainly have an impact on workers. 10 None were observed during the site visit. Page 30 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 The impact on construction workers is assessed as medium The impact on neighboring farmers is assessed as minor receptors (neighbor’s farmer). 5.3.1.4 Impact on worker health and safety Potential safety and health impacts to workers during construction of the Zefta PRS, in general, are the same as those associated with any construction project involving earthmoving, use of large equipment, transportation of overweight and oversized materials, and construction and installation of facilities. In addition, health and safety issues include working in trenches. The occupational health and safety impacts is assessed as medium 5.3.1.5 Risk pertaining to child labor As mentioned in the baseline, child labor is a common practice in the project communities in Al Gharbia. Children below 18 work almost in all developmental projects as they receive low salaries and they are less demanding. This risk should be carefully handled in the ESMP and restrict obligations and monitoring should be applied in the contractor and subcontractors obligations. Rigid penalties should also be applied to the contractor and subcontractors in case of breaching child labor restrictions. Child labor risk is assessed as low to medium 5.3.1.6 Hazardous and non- hazardous waste management Normal construction non-hazardous solid wastes includes scrap concrete, steel, bricks, packaging waste, used drums, wood, scrap metal, and building rubble will be generated. Human or domestic wastes by construction labor, including sewage and garbage collected from the labor offices location will also be generated. Disposal of sewage and garbage generated from construction labor, if not transported to adequate sites, will be a continuation of the existing sanitation situation and contribute, although to a relatively low extent, to environmental deterioration. Solid hazardous waste generated is likely to include empty containers, spent welding materials, solvents, paints or adhesives, and other hazardous waste resulting from operation and maintenance of the equipment and vehicles, i.e. spent oils, spent lube, waste oil filters, batteries, etc. Among the hazardous wastes also are the wasted or faulted materials. Adverse impacts on the environment from the possible improper disposal of the solid wastes and hazardous waste. Therefore impact is assessed as medium 5.3.1.7 Traffic impact Environmental impacts The greatest potential for traffic impacts to occur arises during the short period where construction works peak (transportation of raw materials, equipment, and foundation materials). The traffic flow that will be created during the construction period will to some extent depend on which type and number of trips to and from the proposed site. Additional activities, such as entering and exiting the site will not have significant impacts on the road given the proposed site is directly located on the Banha-Zefta road. Page 31 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 Based on observation during the site visits, it is predicted that during transportation of the equipment and raw materials, only one lane will be used by the trolleys and the movement of one trip will not last more than 8 hours (during the midnight – morning). Socioeconomic impacts The project will result in inconvenience and disturbance to local communities and businesses causing delays in the various daily activities due to the fact that microbuses and tuk tuks may find difficulty in maneuvering in the main roads in the vicinity of the Zefta PRS. Moving the PRS equipment might result in short term disturbance to the community. Therefore impact on traffic in the project site is assessed as medium 5.3.1.8 Impact on ground water /Surface watr Groundwater may be impacted in case of improper disposal of sanitary wastewater, construction wastes or debris (generated from activities like ditching, and excavation). Generated sanitary wastewater, as well as water resulting from the dewatering activities (if exist) during excavation, will be collected in tanks and transported via a certified contractor to the nearest wastewater treatment station. Therefore impact is assessed as minor 5.3.1.9 Ecological impact As described in the baseline section, the proposed project site is not characterized by the presence of endangered species. The project site is characterized by agricultural land, and only some non-significant exotic floral species such as grasses, and stray dogs and cats, were recorded in the project area. Therefore it is assessed as of no significance impact 5.3.1.10 Community health and safety The proposed project site located approximately 150 m from a rural area, the impact on the community as a result of exhaust gas emissions, dust and noise is likely to be temporary and short term and therefore is predicted to be minor. Therefore it is assessed as minor 5.3.1.11 Land related impact Socioeconomic impacts  Zefta PRS required a plot of 23265. m2. In 2012, the LDC that was responsible of constructing Zefta PRS was Maya Gas. They were also responsible for purchasing lands needed to construct the PRS. Thereafter, they handed over the construction of the PRS to Egypt Gas. Therefore, it was relatively difficult to define how the process was implmeneted. Given the absence of any information about land acquisition process, the study team conducted meetings with Egypt Gas and EGAS social team for better understanding of the process as Maya Gas was not operating in Zefta any more. Additionally, all land contracts were obtained from EGAS (see Annex 2). Page 32 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 They reported that the process of land acquired was as follows: o Maya Gas followed EGAS regulations( no enforcement in land purchase) pertaining to purchasing any PRS lands. They visited the project site seeking for lands free of any customary landownership and the owners expressed their willing to sell their lands; o At the time of handing over the land from Maya Gas to Egypt Gas, the lands were free of any land disputes and had legal and acceptable land tenure without any legal conflicts; o Maya Gas agreed to purchase three plots of land that the owners approved willingly to sell them to the LDC of proper market value; o Three contracts were signed with the owners in 2012; o All lands were taken without any disputes or legal lawsuits. A site visit was paid by the study social team to land site in 2016, the site was fenced and no encroachments were detected. Impact related to the land acquistion during the construction phase is assessed as of no significance as land ownership was based on willing buyer willing seller approach 5.3.1.12 Visual intrusion and landscaping During the construction of the PRS visual intrusion is likely to occur due to moving construction materials and vehicles inside the agricultural lands. Given the fact that the PRS land is fenced, the probability of this impact tends to be of no significance. Impact related to the visual intrusion during the construction phase is assessed as of no significance 5.3.1.13 Labor influx The LDC recruits a number of workers and technicians during the construction phase. If not managed properly, the recruited workers’ interactions with the local community may result in inconvenience, inappropriate and unappreciated acts, negative impacts on privacy or may even result in serious misconducts (e.g. harassment) or inappropriate behaviors that could affect different groups including women. Although not very much expected in the project, In the meantime the increase of workers might mean in some areas influx of additional population and increased pressure on local resources, prices of commodities, accommodation and rents. In Zefta PRS, only 16 workers will come from outside Zefta. Such a number is likely to cause minor labor influx impacts. Impact related to the labor influx during the construction phase is assessed as low Page 33 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 5.3.2 Negative impacts during operation 5.3.2.1 Impact on worker health and safety Possible impacts to health and safety during operations include exposures to odorant release, gas leak, fire , noise, accidental injury to workers. In addition; health and safety issues include working around energized equipment, and possible contact with natural hazards. However, during the operation and maintenance phase, if there is any incident or emergency situation, the impact will negatively endanger the surrounding community and establishment. Odorant handling is part of the operation of the PRS and is addressed in a Quantitative Risk Assessment (Annex 10) attached as a separate study. An odorant is added to the NG in order to enable detection upon leakage. The odorant containing Tertiobutylmercaptin (80%) and Methylehylsulphide (20%) is classified as a hazardous substance. The MSDS of the odorant identifies the following hazardous properties: Highly flammable, flammable and toxic products upon thermal decomposition, irritant, and toxic to aquatic flora and fauna.Odorant spills can result from improper handling of the odorant tanks. In case of emergency, the risk resulting from odorant release or gas leak will be managed by Zefta PRS’s emergency response plan. Therefore the impact is assessed as medium 5.3.2.2 Risk pertaining to child labor Given the permanent nature of job opportunities during operation phase, children below 18 are not allowed to work in the PRS. Consequently, this risk is not valid in the operation phase. Child labor risk is assessed as of no significance 5.3.2.3 Hazardous and non-hazardous waste generation During operation and maintenance of the PRS, besides industrial hazardous (odorant containers) and non-hazardous waste, small quantities of domestic waste (solid and liquid waste) will be generated. Industrial hazardous waste is likely to be generated during routine operations (e.g., lubricating oils, odorant containers, chemical containers). These wastes are typically stored briefly, and transported by a licensed contractor to an appropriate permitted off-site disposal facility as a standard practice, according to EEAA regulations for hazardous waste management. Poor waste management practices may also have a significant impact on environment (soil, groundwater (if exists), visual, and health and safety). Therefore the impact is assessed as medium 5.3.2.4 Noise impact The pressure reducers normally cause noise generated from the reducers' pipes. Maximum noise level expected from the reducers is 80db. The generated noise is constant (not intermittent). Assuming ambient noise levels are complying with WB/IFC requirements and Law 4/1994- 9/2009- 105/2015 standards for low noise residential areas, a 20-meter buffer distance kept between the reducers and the PRS fences should lead to minimal impact outside the PRS borders. Additionally, the PRS is located at the Banha-Zefta road where the noise baseline was recorded is range between 56.9 to 68.6 LAeq. Therefore the impact is assessed as minor Page 34 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 5.3.2.5 Air emissions No gaseous emissions are expected to occur during the operation phase except for the accidental natural gas leak or in case of accidents (odorant handling or storage) and during maintenance activities. Therefore the impact is assessed as of no significance 5.3.2.6 Soil impact The normal operation of the PRS will not have an impact on soil; however risk of soil contamination is only associated with the possible spillage or leakage. Therefore the impact is assessed as of no significance 5.3.2.7 Ecological impact The normal operation will not have an impact on flora and fauna. Therefore the impact is assessed as of no significance 5.3.2.8 Traffic impact During the operation and maintenance of the PRS, there will be no expected impact. There will only be a small number of staff vehicles moving in and out of the PRS, as well as trucks transporting odorant and spare parts to the PRS. Traffic impacts are anticipated to be insignificant due to the proposed project being located at the Banha- Zefta road. Therefore the impact is assessed as of no significance 5.3.2.9 Labor influx Zefta PRS will employ between 12 and 14 workers, and therefore having no significant impact pertaining to labor influx. Therefore the impact is assessed as of no significance 5.4 Impacts during Accidental Events (Operation Phase) Regarding to the Quantitative Risk Assessment Study (QRA), which demonstrate on the following hazards:  Gas Release  Fires (Heat Radiation)  Explosion (Overpressure Waves)  Suffocation (Odorant Leak) And referring to the risk calculations determined in Zefta QRA study, the individual risk level to the exposed workers / public (PRS / Off-take Point)) based on the risk tolerability criterion have been identified in Acceptable (Lower Tolerability Limit11) for workers / Off-take public 11 Below the Upper Tolerability Limit The risk is only tolerable if it is ALARP. This means that all practicable risk reduction measures must be identified and those that are reasonably practicable implemented. The term reasonably practicable indicates a narrower range than all physically possible risk reduction measures. If the cost of a risk reduction measure, whether in terms of money, time or trouble, can be demonstrated to be grossly disproportionate to the risk reduction gained from the measure, taking account of the likelihood and degree of harm presented by the hazard, then implementation of the measure may not be required. Page 35 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 and ALARP (Below the Upper Tolerability Limit(12)) region for public (PRS). So there are some points (Study Recommendations) need to be considered to keep the risk tolerability, and this will be describe under item (7.5) (for more details refer to the QRA Study under Annex-10) Therefore, the impact is assessed to be of Low significance. 12 Lower Tolerability Limit Which the risks are broadly tolerable to society and comparable to everyday risks faced by the public. If the overall risk is below the Lower Tolerability Limit, the ALARP Assessment is likely to be straightforward and limited to ensuring compliance with Good Practice. Below the Lower Tolerability Limit, the principal risk management concern is the maintenance of existing risk reduction measures to avoid degradation.

Medium on unpaved surface soils during site preparation and foundation-laying could cause a physical breakdown of soil particles potentially causing destabilization of the soil structure. Air emission WB/IFC requirements and Law 4/1994 (modified by laws 9/2009 & Negative impact Medium 105/2015) stipulates strict air quality standards. Air emissions (gases and particulates) during construction shall arise from: - Particulate matter and suspended solids from excavation/backfilling operations - Possible dispersion from stockpiles of waste or sand used for filling trenches. - Exhaust from excavation equipment and heavy machinery (excavators, trenchers, loaders, trucks) containing SOx, NOx, CO, VOCs, etc. - Traffic congestions resulting from road closure or slowing down of traffic due to excavation works. Dust The impact of dust generation (particulate matter) will be limited to the working hours as excavation and other construction activities. Which lead to temporary reduction of air quality, however is unlikely to cause major air emissions impacts as the nearest receptors are around 100 m from the PRS construction site.

Noise Noise impact on worker Negative impact Medium Noise impacts on construction workers, technicians and engineers in direct vicinity of the excavation works and heavy machinery are considered more significant than those on residents. Noise impact on neighbor Negative impact low Minor No major noise impacts are expected during construction of the PRS as the momentum intensity nearest receptors are around 100m away and the construction period is and effect limited.

Children below 18 work almost in all medium projects as they receive low salaries and they are less demanding. This risk should be carefully handled in the ESMP and restrict obligations and monitoring should be applied in the contractor and subcontractor obligations Hazardous and non- Inappropriate waste disposal and improper management of construction Negative impact Medium hazardous waste waste materials which could lead to spillages that will cause soil generation contamination. Excavated soil and concrete/bricks waste are inert materials. Improper disposal of such wastes will only have aesthetic effects on the disposal site.

Zefta’s PRS will produce 7 bar outlet pressure for the local distribution network (intermediate pressure). The LDC (Egypt gas) choose to produce 7 bar instead of 4 bar due to high consumption rates excepted in Zefta city. It is designed to accommodate future extensions to the distribution network (intermediate pressure) in order to feed other cities and/or villages in the district. 6.1.2 Odorant Handling Environmental and safety control considerations and measures are integrated into the selected technology design. For example, in order to reduce emissions from the odorant unit, the odor will be automatically added or by using a plunger pump. Automatic and sophisticated unit management systems ensure safe and easy operation and can encompass complete remote operation of the units. 6.2 PRS location Alternatives As per national and WB guidelines, PRS siting avoids habitat alteration and seeks to minimize environmental, occupational health and safety, and community health and safety impacts. In 2012, the LDC that was responsible of constructing Zefta PRS was Maya Gas. They were also responsible for purchasing lands needed to construct the PRS. Thereafter, they handed over the construction of the PRS to Egypt Gas. Therefore, it was relatively difficult to define how the process was implmeneted. Given the absence of any information about land acquisition process, the study team conducted meetings with Egypt Gas and EGAS social team for better understanding of the process as Maya Gas was not operating in Zefta any more. In general, EGAS and LDCs follow a set of agreed upon procedures for the process of permanent Land take for the construction of PRSs. The procedure covers cases of land acquisition of State Owned Lands or privately owned Lands on willing Buyer Willing Seller basis. It is the priority of EGAS as an asset holder, to acquire State Owned Lands that are free of any uses (both formal and informal EGAS never resorts to the land expropriation decrees in PRSs selection, particularly because of the flexibility of the PRSs locations. In cases of unavailability or in case the available land is technically unacceptable, private land is usually used as a second a resort. Land alternatives are examined and the optimum technical and socio-economic scenario of land is selected. Consultation activities are conducted through the project cycle with the individuals who offer to sell their land, dissemination of project information at the early stages of the project during the frameworks preparation followed by consultation activities with the Project affected persons (e.g. cases of farmers whose land are temporary affected from the high pressure pipelines passing their land) and during land acquisition with land owners. Page 43 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 7 Environmental and Social Management & Monitoring Plan 7.1 ESMMP Objectives The Environmental and Social Management and Monitoring Plan (ESMMP) consists of a set of mitigation, management and monitoring measures to be taken during implementation of the project to avoid, reduce, mitigate, or compensate or offset any adverse social and environmental impacts analyzed in the previous chapter. The ESMMP distinguishes between mitigation measures and monitoring that should be implemented during the construction and operation of the project as well as estimate costs for these mitigations. The ESMMP identifies certain roles and responsibilities for different stakeholders for implementing, supervising and monitoring the environmental and social performance of the project during its life cycle. Roles and responsibilities for implementing the ESMMP during the construction and operation phases have been proposed. During construction EGAS/LDC will assign supervision staff who will undertake supervision over the contractor to make sure that the mitigation measures specified in the design/tender document are implemented on field. During the operation phase, the PRS shall have at least one permanent staff member for health, environment and safety. Overall, the following Environmental and Social measures are complementary to and do not substitute compliance to the detailed HSE guidelines, procedures, and actions adopted by EGAS and its subsidiary Local Distribution Company (LDC). In the following management and monitoring measures the term LDC refers to the gas company in charge of project implementation: Egypt Gas. 7.2 Management of Grievance EGAS and the LDCs are committed to preventing, limiting and, if necessary, remedying any adverse impacts caused by its activities on local populations and their social and physical environment. Identifying, preventing and managing unanticipated impacts are facilitated by a grievance redress mechanism (GRM). As the World Bank’s governance and anticorruption (GAC) agenda moves forward, grievance redress mechanisms (GRMs) are likely to play an increasingly prominent role in Bank-supported projects. Anyone will be eligible to submit a grievance to the Project if they believe a practice is having an adverse impact on the community, the environment, or on their quality of life. They may also submit comments and suggestions to the GRM. The GRM was designed in order to handle all grievances during the construction and operation phases. The aggrieved person has the full right to lodge his complaint anonymously. However, this might cause a challenge to inform him about any corrective procedures. Additionally, if the complaint is related to service seeking, the aggrieved person should provide full information about himself and about his residential unit. Page 44 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019 Objectives: The objective of a grievance procedure is to ensure that all comments and complaints from any project stakeholder are considered and addressed in an appropriate and timely manner. This will manage to build trust and detect any weak signal. The process will reduce risk of litigation and conflicts with the community Disclosure of the GRM: The Community people will be fully informed about the Grievance procedures in simple language. Information about grievance mechanism will be tailored according to the community. All information about GRM will be made available on the contracting offices during the construction phase and on customer services offices during the operation phase. Mode and channels of Grievance: The Company will accept all comments and complaints associated with the project from any stakeholder. Comments can be made via email, post, fax, on the telephone or in person. The comments and complaints will be summarized and listed in a Complaints/Comments Log Book, containing the name/group of commenter/complainant, date the comment was received, brief description of issues, information on proposed corrective actions to be implemented (if appropriate) and the date of response sent to the commenter/complainant. The proposed mechanism is built on three tiers of grievances: - The foreman working on the ground in PRS site in Zefta, - The project manager in PRS site in Zefta, - The regional department of Egypt Gas in Gharbeya Governorate The aggrieved person has the full right to immediately use tier 2 or 3 upon his convenience and there is no need to exhaust the first tier. Additionally, he can resort to any other governmental entities i.e. Ministry of Petroleum. He/ She also have the full right to bring a lawsuit without resorting to any of the grievances tiers. Grievance channels: 1. During construction phase: a) Foremen act as the main channel for complaints. They are always available on the construction sites.

The Second level of Emergency:  There is a serious risk to life, safety, property and the environment and may exceed the limits of the emergency zone, but do not exceed the limits of the public site or facility.  There is a need to use the assistance of external parties to manage the emergency, or at least the presence of stand-by team in the presence of a potential escalation of the situation, but the situation does not extend its influence outside the facility or site.  Members of the facility or site do not have sufficient capacity or resources to deal with the incident  Requires evacuation and / or warnings to warn those outside the emergency zone Page 57 Site-specific ESIA NG Connection 1.5 Million HHs-Gharbeya Governorate/Zefta PRS –Final Report- April 2019  Security breach or situation leading to constant threat to life and safety  Accident management team intervenes The Third level of Emergency:  There is a serious risk to life, safety, property and the environment and may exceed the limits of the emergency zone and the possibility of exceeding the limits of the public site or facility.  There is a need to use the help of external parties to fight fire, rescue, dealing with hazardous materials, large number of injuries and deaths.  Measures must be taken to protect units, nearby areas and / or communities and the environment beyond the boundaries of the public site or facility  There is a potential risk that the reputation of the company, its business or its revenues will be affected  Any incident involving the exit of the operating system beyond the limits of safe operation with the possibility of escalation  There is a danger to the public  There is a possibility to start or run the communication system for emergency reporting  The accident management team is used. 7.7.1 Hotline A 24-7 Hotline (129) is available for customers and the public to report leaks, damage, emergencies, and/or incidents related to gas connections, components, infrastructure, and activities (inside or outside households) and to request repairs/emergency response/assistance. 7.8 Institutional Framework for ESMMP Implementation 7.8.1 Environmental Management Structures EGAS is the supervisory body. Egypt Gas is the implementing body. Below is the management structure of Egypt Gas. Being the implementing body of the natural gas network in project areas, Egypt Gas has a direct involvement with the environmental management and monitoring of the natural gas network. Egypt Gas has limited environmental and social background. Therefore, an upgrade in their environmental and social capacity will be necessary. EGAS will be responsible for providing Egypt Gas staff with the needed information. One of the standard tasks of the HSE Departments of Egypt Gas, supervised by EGAS, is to ensure that the Environmental and Social Management Plan of the project is implemented in all the phases of the Project, through establishing an Environmental Register for Pressure Reduction stations, with frequent auditing of this register.

The main identified groups are very similar to those identified on the governorate level but on a smaller scale, (elaborated details on that are included in the Governorate level ESMP).
