So, we cannot directly interpretate these limits for COMP3 Project facilities. These values can be used for reference purposes.
6.3 Stack Emissions
There are no permanent and continuous emission stacks in COMP3 Project facilities. So, offshore facilities, Qatar Oil and Gas Industry stack emission standards are not specified in this Design Basis.
6.4 Ozone Depleting Substances
The State of Qatar has signed and ratified the Montreal Protocol in 1996. PROJECT design shall comply with the provisions defined in the Montreal Protocol on prohibiting systems filled with chloro-fluorocarbons (CFC), hydrochlorofluorocarbons (HCFC) or halons listed as banned or to be banned, under the Protocol. These materials are considered to cause depletion of the ozone layer in the stratosphere and initiate other environmental damage [Ref.41]. As permitted by the Montreal Protocol the PROJECT shall use hydrofluorocarbons (HFC), which are not harmful to the stratospheric ozone although HFCs are to be phased out in Qatar in 2028 as per the Kigali Agreement of the Montreal Protocol. Alternatives to HFCs include natural refrigerants (e.g. propane or ammonia based), hydrofluoroolefins (HFOs), and HFC-HFO blends can be used.
6.5 Flaring / Venting
The Flare System will be provided for emergency and maintenance depressurization of the topside equipment and piping in COMP3 Project.
Flare KO Drum only exists in WHP13N. In all other platforms, only Closed Drain Drum is available. A common Flare KO / Closed Drain Drum shall be considered to collect fluids from closed drain header and flare header [Ref.30].

COMP3 - NFPS OFFSHORE RISER/WELLHEAD PLATFORM & INTRAFIELD PIPELINES PROJECT
ENVIRONMENTAL BASIS OF DESIGN FOR COMP3 PROJECT
The RP5S will be connected to the existing wellhead platform WHP5S which does not have a permanent flare system. A vent header on RP5S will be provided to gather all the manual vent lines and future Test Separator PSV and route these to the existing vent system on WHP5S. Therefore, a future Flare Header, to future compression platform (CP7S), will be provided on RP5S to accommodate emergency topsides depressurization loads [Ref.31].
The RP9S will be connected to the existing wellhead platform WHP9S which does not have a permanent flare system. Two flare headers will be included on RP9S to collect and route the pipeline depressurization lines to WHP9 temporary Low Capacity and High-Capacity Flare Tips. A vent header on RP9S will be provided to gather all the manual vent lines and future Test Separator PSV and route these to the existing vent system on WHP9 [Ref.32].
The riser platform RP6N is bridge linked to WHP6N which does not have a permanent flare system. On WHP6N, space is provided to install a temporary flare system for trunkline and for intra-field pipelines manual depressurization. Vent header is included in RP6N to gather all the manual vent lines, excluding from the future Test Separator and route it to WHP6N Closed Drain header, to be further collected in Closed Drain Drum and relieved to atmosphere at safe location. Relief / vent from future Test Separator will be routed to future compression platform CP6N [Ref.29].
A venting system shall be applied to maintain atmospheric pressure in the open systems and in non-blanketed storage tanks. A slightly positive pressure will be maintained in blanketed storage tanks like MEG [Ref.30].
There are two types of vents:
- To atmosphere at a safe location (toxic, flammable and asphyxiating streams), and
- To atmosphere (all non-hazardous venting).
It is noted that hydrocarbons, flammables, or other toxic vapor mixtures venting to atmosphere shall not be permitted and avoided as practicably possible. The discharge of all atmospheric vents shall be at a safe location away from personnel and areas where personnel may be present and away from areas where vented vapours can collector accumulate, outside of building, away from the hot exhaust or other ignition sources and away from ventilation intakes and also access or passageway.
Equipment and systems shall be vented to atmosphere at safe location and shall include open drain systems, diesel storage tank (equipped with flame arrestor), MEG tank with nitrogen blanketing, nitrogen system, chemical injection system (as necessary for the chemicals selected). Separated gas from Closed Drain Drum from RPs & WHP is routed via vent line.
Low pressure atmospheric tanks and vessels containing non-volatile liquids such as diesel fuel, treating chemicals, etc. shall be provided with open vent lines as the requirement to vent to “a safe location”. Gas blanketed and atmospheric tanks and other small lighter-than-air vents shall be piped past the edge of the platform for discharging at high, outboard points. Vapor from the Open Drain Tank and CP Separator is vented to the atmosphere through a flame arrestor at safe location.
Equipment to be vented to atmosphere include compressed air, instrument air.

Vent dispersion study [Ref.34] will be carried out for vents releases of HC, H2S and N2 gases for credible scenarios to determinate the final location at safe position of vent pipe termination.
As per IFC guidelines [Ref.56], continuous venting is not considered GIIP and should be avoided. Hydrocarbon gas streams should always be routed to an efficient flare gas system including during emergency events or process upset, although continuous flaring of gas should also be avoided wherever practical and possible. Adequate assessment of alternatives should be conducted and if flaring is the only viable option, elimination of continuous flaring shall be achieved.
6.6 Fugitive Emissions
Fugitive emissions of hydrocarbons shall be minimized through a combination of good engineering design practices and good operation and maintenance practices for reducing fugitive gaseous compounds that affect air quality. All valves in Sour Service NACE shall be fugitive emission tested as per ISO 15848-2 class B with 10% of test in case of failure upgrade at 100%. A Leak Detection and Repair Program (US EPA Leak Detection and Repair: A Best Practices Guide) will be implemented during PROJECT facility operations to minimize fugitive CH4 and/ or VOC emissions. Other specific measures to be implemented as necessary, wherever practicable, including:
• Routing the discharge of safety relief devices in hazardous services to a closed flare
system;
• Using plugged or capped ends on drain valves, sample valves and test connections to
minimize emissions from open-ended connections; • Using closed-loop sampling systems where possible; • Using suitable pump, compressor seals to minimize gas release; • Minimizing the number of flange fittings; • Using welded pipework and low leakage valve systems; Implementing leak detection and repair programs; and • Installing vapor control units for hydrocarbon loading and unloading. •
6.7 GHG Emissions
The State of Qatar has signed and ratified the Kyoto Protocol in 2005 [Ref.45]. The Kyoto Protocol aims to limit the emissions of six GHGs, namely carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrochloro-fluoro-carbons (HCFC), perfluoro-carbons (PFC) and sulfur hexafluoride (SF6). The PROJECT shall employ effective energy efficiency measures with regards to minimizing CO2 emissions arising from fuel gas combustion.
6.8 Vessel Emissions
Although the State of Qatar has not signed the Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL) on the Prevention of Air Pollution from Ships, QG has committed to meet the Annex VI requirements [Ref.49]. Therefore, all vessels involved in the PROJECT (including rigs) will require adherence to MARPOL Annex VI requirements including possession of a valid International Air Pollution Prevention (IAPP) certificate.
Atmospheric emissions from vessels at all phases of the PROJECT shall adhere to MARPOL Annex VI requirements, notably:

6.9 Effluent Discharges
PROJECT activities will generate liquid, semi-solid and solid wastes that will need to be disposed of safely without causing harm to the environment or personnel. These discharges require specific management to reduce the risk of harming the environment and personnel to the level of ALARP. Offshore wastewater discharges will comply with the limits prescribed by the Executive by Law No. 4 (2005) (Environmental Protection Standards) [Ref.2]. In the absence of any specific Qatar limits, relevant international standards and guidelines shall apply. For existing facilities, the discharges are required to meet ROPME Protocol requirements [Ref.47].
Potential effluent sources from the COMP3 Project are limited to the following:
• Hydrotest water from pipeline commissioning; • Deck drainage; • Overboard discharge; • Produced water.
Effluent management principles should include the following:
• Water use to be minimized and wastewater reused (following appropriate treatment)
or recycled, wherever practicable;
• Risks of contamination to the environment must be minimized; • Discharges shall be in compliance with Qatar water discharge limits as detailed below; • Appropriate engineering controls shall be in place to prevent leakages from pipes and
vessels, including regular maintenance and inspection to detect leaks;
• Adequate spill control (bunding/ coaming) and drainage arrangements shall be provided where hydrocarbon and chemical inventories are stored, handled or processed; and
• All environmentally harmful liquids shall be stored on a hard-surfaced coaming area to
act as a barrier to prevent pollution.
6.9.1 Hydrotest Water
Hydrotest water shall be monitored to meet Qatar legislative discharge standards in the marine environment [Ref.2]. In the absence of specific guidelines on hydrotest water management in Qatari Law, the pollution prevention and control measures outlined in the IFC guidelines [Ref.52] shall be applicable, as follows:
• Minimize the volume of hydrotest water offshore by testing equipment at an onshore
site prior to loading the equipment onto the offshore facilities;
• Use the same water for multiple tests;

• Reduce the need for chemicals by minimizing the time that test water remains in the
equipment or pipeline;
• Carefully select chemical additives in terms of dose concentration, toxicity,
biodegradability, bioavailability, and bioaccumulation potential; and
• Send offshore pipeline hydrotest water to onshore facilities for treatment and disposal,
where practical.
A hydrotest water management plan will be developed by Contractor’s concerned discipline and reviewed and approved by engineering discipline of the Company.
6.9.2 Deck Drainage
Drainage system is split into three systems: Open Drain System, Closed Drain System and Maintenance Drain.
6.9.2.1 Open Drain System
The Open Drain System shall be provided on both the Wellhead Platforms and the Riser Platforms. Open Drain System is segregated into hazardous and non-hazardous open drains. Hazardous drains are open drains collected from hazardous area Zone 0/Zone 1/Zone 2 and non-hazardous drains are open drains collected from non-hazardous area. The segregation is meant to avoid migration of a fire, flammable liquids or vapours, or toxic liquids or vapours from one hazardous area to another, or to a non-hazardous area. Liquid seal is provided at the end of both hazardous and non-hazardous header to prevent gas migration.
Hazardous area drip trays, hazardous area deck drain from wellhead and riser platforms shall be collected via gravity flow headers to Open Drain Tank. The Non-Hazardous Area Open Drain System shall collect drainage from non-hazardous areas of platform, such as rainwater, washdown water, deluge etc., via gravity flow headers. [Ref.31].
Open Drain Tank will be sized to provide a minimum of 10 minutes retention time for the amount of rainfall collected on the plated areas of the deck during a 10-year rainfall event. The Open Drain Water Pump and the CP Separator will be sized to handle the amount of rainfall collected on the plated areas of the deck during a 50-year rainfall event. The Open Drain Oil Pump capacity will correspond to minimum 10% of the capacity of the Open Drain Water Pump [Ref.28].
Open Drain Tank shall be a rectangular atmospheric tank provided with two compartments: one compartment collects the liquids from open drain headers and the other receives the oil from the CP Separator. The separated water in the Open Drain Tank is pumped to the CP Separator for further treatment prior to disposal overboard. Recovered oil collected from the CP Separator skim bucket will be drained to oil compartment of Open Drain Tank. Oil from the oil compartment of Open Drain Tank will be pumped to the Closed Drain Drum.
Overflows from Diesel Storage Tank sent to oil compartment of Open Drain Tank and subsequently to Closed Drain System via Open Drain Oil Pump. Refer Process Drain Philosophy [Ref.28] for details.

6.9.2.2 Overboard Discharge
The Non-Hazardous Area Open Drain System shall collect drainage from non-hazardous areas of platform, such as rainwater, washdown water, deluge etc., via gravity flow headers. Drainage from some areas (helideck, toilets and AHU, Deluge test line, firewater from wellhead area) where no hydrocarbon spillage can occur should be routed directly overboard rather than to the Open Drain Tank [Ref.24]. In general, all overboard discharges are not expected to be contaminated with chemicals, however, these discharges to sea shall comply with the standards stipulated in Annex 4 under MOECC Executive By-Law [Ref.2 & 20], as given in Table 6–2:

This shall consist of headers segregated according to the piping class, terminating at the Closed Drain Vessel. The liquids collected in the closed drain vessel shall be returned by means of a pump to export header. This closed drain vessel shall not receive effluents from the open drains nor discharge into an atmospheric enclosure receiving open drain effluents. Recovered oil from the open drain tank will be routed to the Closed Drain Vessel.
6.10 Noise
Noise will be emitted from various sources of the COMP3 Project. The main sources of noise are as follows:
• Rotating Equipment (Electric Motors, Pumps, etc.) • HVAC Equipment (Air Handling Unit, Air Cooled Condensing Units, etc.) • Fans • Motor Operated Valves, Flow Control Valves, Flow Meter, Restriction Orifice • Flares & Atmospheric vents • Pressure Safety Valves & Blowdown Valves • Transformers • Hoist motor etc.

With respect to COMPANY’s Noise Control and Hearing Conservation Program 83 dB(A) is the noise limit for an 12 hour TWA exposure.
Absolute limit anywhere in a work area – personnel will not be permitted to work in the area where noise at this level is present. Sound resulting from emergency noise sources such as atmospheric Process Safety Valves (PSVs) and Flares shall not exceed 115 dB(A) at reasonably accessible in-plant locations
There are currently no prescribed limits for underwater noise under Qatari legislation or other applicable international standards or guidelines. Although no prescribed limits are available, the IFC guidelines [Ref.52] provide recommendation on mitigation measures that can be employed to reduce the risk of underwater noise impacts to marine species from noise- generating activities.
In accordance to GIIP, this PROJECT shall employ mitigation methods to mitigate noise- inducing activities to ALARP levels through:
• Usage of quietest possible technology/Equipment; • Employing physical methods to reduce the source level; •
Implementing physical methods to reduce the transmission of sound beyond the source; and
• Establishing exclusion zones to reduce potential noise exposure to levels causing
injuries or behavioral disturbance to marine fauna.
The other details are mentioned in Noise Design Philosophy for COMP3 Project [Ref.22].
6.11 Lighting
Without compromising safe workplace lighting conditions, the PROJECT shall minimize environmental and visual impacts. In EIA report [Ref.20], it is mentioned that artificial lighting

ENVIRONMENTAL BASIS OF DESIGN FOR COMP3 PROJECT
impact will be highly localized and of minor consequence to the ecosystem from the facility. These artificial lighting effects are already present at the existing platforms in the area, and hence they may not be impact for this PROJECT.
In the absence of any legislative requirement for light emissions for Qatar, OSPAR [Ref.46] for minimizing impacts of lighting to biodiversity receptors shall be considered, including the following:
• Assessing all lighting equipment on offshore installations potentially emitting light outside the physical boundary of an installation to determine whether the light is essential for safety reasons and whether there is potential for reducing external emissions;
• Reducing the number of lights and intensity of lights, and adapting the light spectrum
•
to those that will have low impacts to biodiversity; In areas where lighting is not a continuous requirement, installation of automatic switches and light sensors should be considered. Otherwise, light sources should be automatically or manually controlled through the process control system. Normally unmanned platforms should have switches installed and during unmanned periods light should be switched off apart from lighting requirement to comply with national and international regulations on aviation and shipping navigation; and
• Where possible, external lights should be shielded to direct light only to areas where it is needed, and lights should be positioned in places where emissions to the surrounding environment can be minimized. Plant lighting will be designed as per Electrical Basis of Design for COMP 3 Project [Ref.35].
6.12 Chemical Management
Chemical selection shall be in alignment with ROPME protocols [Ref.46] and guidelines and according to the lowest toxicity, lowest bioaccumulation potential and highest biodegradation potential, as applicable. Chemicals shall be selected according to the harmonized pre- screening scheme based on the OSPAR methodology [Ref.47].
All chemicals selected for the PROJECT shall be registered in the Offshore Chemical Notification Scheme (OCNS) and regulated according to Harmonized Offshore Chemical Notification Format (HOCNF) and ranked as GOLD/ SILVER under the Chemical Hazard Assessment and Risk Management (CHARM) model or classified as chemicals with the least environmental risk (Category C to E) ranking for non-CHARMable products. Chemicals listed as Posing Little Or No Risk (PLONOR) under the OSPAR list are preferred.
Chemical storage areas shall adhere to the following requirements:
• Hazardous waste must be placed, stored in UN approved drums/containers, labelled and transported onshore for waste disposal or treatment in an MOECC approved facility;
• Each chemical container shall have hazard labelling according to UN Globally
Harmonised System for Classification and Labelling of Chemicals (GHS);
• Only chemicals approved for use should be stored in the site storage facility, while those not yet approved shall be quarantined, controlled and monitored in a dedicated area until cleared;
• Only authorised personnel shall have access to the chemical storage area;

• The first- expire / first- out principle shall be implemented in order to reduce the
possibility of having expired chemicals in stock; and
• Site is responsible to maintain and update its chemical inventory.
All storage areas for chemicals must be designed so that risk to personnel and the environment is minimized. The key areas which must be addressed for storage areas include:
• Spill containment; • Coaming requirements; • Separation of storage area from offices, boundaries and the like; and • Segregation of incompatible chemicals.
6.13 Solid Wastes
The ‘Duty of Care’ principle shall be adopted for the management of waste streams generated by the PROJECT’s facilities. Under the ‘Duty of Care’ principle, the waste producer (COMPANY) shall be responsible for ensuring the proper and safe disposal of wastes, even after it has been passed to another party. The Duty of Care for waste cannot be contracted away or delegated to a third party. The COMPANY is required to take all reasonable steps to manage any waste it generates and ensure its lawful disposal. A Waste Management Plan (WMP) documenting the waste strategy, storage (including facilities and locations) and handling procedures should be developed as recommended in the IFC guidelines [Ref.51, 52]. The WMP should also include a clear waste tracking mechanism to track waste consignments from the originating location to the final waste treatment and disposal location.
As a minimum, the following shall apply:
• No floating foams or any solids may be discharged to sea; • All domestic waste shall be segregated to biodegradable, recyclables and reusables,
and transported to shore for disposal; and
• All hazardous waste shall be stored in a designated area prior to being transported to
shore for disposal at an approved MOECC facility.
The waste storage area shall be segregated for non-hazardous and hazardous wastes, and labelled accordingly. Non-hazardous wastes shall be further segregated based on its chemical and physical properties (e.g. biodegradable, recyclable, etc.). Hazardous wastes shall be managed according to International Maritime Dangerous Good (IMDG) Code and Qatar legislative requirements. Hazardous wastes shall be packaged and labelled accordingly throughout its storage prior to being transported onshore for treatment and/ or disposal. Refer Section 6.14 Hazardous waste for details.
No sand production is expected since the reservoir is of carbonate formation and the offshore wells are not designed for sand production consequently.
Ship waste is to be managed in accordance with MARPOL Convention. Macerators or incinerators shall also be provided onboard and ship waste should not be discarded within 500 meter zone [Ref.49]. Any applicable waste discharged to sea shall be macerated to an approved size as per MARPOL requirements. Waste materials shall be segregated into non- hazardous and hazardous waste for appropriate management. For non-hazardous wastes, disposal of non-hazardous solid and non-biodegradable wastes into the sea is not permitted with the exception of macerated food wastes. Non-hazardous wastes are to be segregated

accordingly to its chemical and physical properties and transported onshore for disposal or recycling by a government approved contractor.
6.14 Hazardous Waste
Hazardous materials shall be handled as per COMPANY Procedure [Ref.11]. Hazardous waste shall be managed according to International Maritime Dangerous Goods (IMDG) Code [Ref.55], UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS) [Ref.60] and Qatar legislative [Ref.2] requirements. Hazardous wastes shall be packaged and labelled accordingly prior to delivery onshore for treatment/ disposal by a government approved contractor. Selection of waste treatment options shall take into account BAT principles, minimization of risk and long-term liability.
As the presence of Mercury is anticipated in the separator gas as trace contaminant, the COMP3 Project shall adhere to the seawater quality standard as stipulated under Qatari legislation [Ref.4], where the concentration of Mercury in seawater shall not exceed 0.4 µg/l. According to the QG-S RGE Compression BOD [Ref.23], Mercury levels will be monitored quarterly based on EPA 245.2 AA Cold Vapor method and concentration is expected to be within 1 µg/m3 (or 0.001 µg/l), therefore is compliant with Qatari legislation [Ref.2].
Traces of Mercury, Arsenic, Radan etc. are reported in gas composition [Ref.25]. However, these traces are not directly discharging into either in air environment or marine environment or in the form of solid waste from COMP3 Project.

The following principles shall also be applied to mitigate impacts on environment from an emergency event occurrence:
• All flammable, toxic and waste fluid from the emergency condition, start - up or maintenance or operational relief/ depressurization requirements for all hydrocarbon process systems will be routed to the flare system. • Installations shall be designed to avoid risks of leak of toxic gases and liquid [Ref.38] • Adequate gas detection and mitigation measures shall be implemented to minimize
H2S emissions during loss of containment incidents [Ref.38].
• The QG field is not an oil-producing field and the export will be condensate and gas, hence the risk of oil pollution could arise from diesel. Refer to the Marine Operation Manual [Ref.5] for oil pollution control measures.
• Adequate spill control (bunding/ coaming) and drainage arrangements shall be provided where hydrocarbon and chemical are stored, handled or processed. Drainage system will take into consideration deluge water where possible [Ref.38].
• Any spillage of fuel must be reported to QG (Operations Installation Manager (OIM) for
•
offshore and Marine Logistic Lead (MLL) for onshore). In the event of any emergency in QG offshore facilities involving hazardous materials, the roles and responsibilities provided in COMPANY’s Offshore Emergency Response Plan will be followed by offshore personnel. Any leaks, spills and unintentional releases should be reported in accordance with COMPANY Procedure [Ref.18] and Emergency Response Plan for Operation Phase for COMP3 Project. Upon completion of emergency response, removal of contaminated material and clean-up will be the responsibility of end user of the Individual Asset or Operations group with support from other QG disciplines.
