These facilities include modular facilities close to the gas wellheads, as well as a number of modular unit process facilities at a Central Production Facility (CPF) located north of the town of De Beque, Colorado. Additional facilities are planned for a series of well-head sites, and a booster compression site that collects and compresses gas prior to sending it to the CPF. This document was prepared to address fire protection concerns at the booster station. It is based upon a previous fire protection philosophy document addressing the CPF. Because of the unique nature of fire and explosion hazards at natural gas facilities, Chevron has planned and designed these facilities to incorporate fire prevention and protection systems and procedures in accordance with industry standards, relevant building and fire protection codes, and Chevron's Safety in Design program. The purpose of this document is to present the design and operational philosophy Chevron proposes for the development of these facilities within the booster station. The key design parameter in the design of the fire protection system for the booster station is the ability to quickly and automatically depressure most of the facility, shut down the flow of hydrocarbons to the facility, and remove all electrical power, except essential power, upon automatic detection of a fire anywhere in the facility. As is typical in the petroleum industry, Chevron has designed the production and treatment facilities at the booster station as a series of modular unit processes. Each module is designed to accomplish some function or functions related to natural gas processing, such as removal of water and solids flowing within the gas stream, removal of heavier hydrocarbons from the gas stream, compression of the gas prior to release to a pipeline, metering the gas prior to delivery of the gas to the pipeline, etc. Because of the harsh weather conditions at the site, many of these unit processes are enclosed to protect certain equipment and instrumentation from the elements. Some of the process skids will be mostly enclosed; other process modules will have an enclosure around the instrumentation and control equipment only. Most of the process enclosures will be factory built, and Chevron has been working with the Colorado Division of Housing to secure plan reviews and permits for these prefabricated facilities. Some of the facilities will be site-built enclosures, including facilities housing the main booster compression equipment at the station. Additionally, some of the prefabricated facilities will house support and utility processes, but will not house any significant hydrocarbon materials. Because of the nature of the fire hazard associated with the enclosures housing process gases and associated equipment, the primary focus of this narrative will be on the two primary process buildings housing the booster compressors. These process equipment enclosures are classified by the International Building Code (IBC) as buildings with an Occupancy Classification ofH-2. This rating is based on the amount of flammable gas and liquids carried in the equipment and piping within the enclosures. Although buildings with an H-2 occupancy rating are normally required to have an automatic sprinkler system, Chevron is proposing to protect these facilities with a non-water-based emergency system in accordance with the exemptions allowed in IBC Section 903.3 .I. I.!. The design and construction of the process building enclosures have been conducted after identifYing and taking into account the hazards associated with the types of equipment and Page3/14 Chevron Title: BOOSTER STATION FIRE PROTECTION PHILOSOPHY Ill Customer: Chevron Midcontinent SBU Project: Piceance Basin Project Spec No: 2033-105-00-ST-0001-01 Date: 23 April 2009 REV:O Page 4 of 14 materials contained within the enclosure. The design and construction .standards utilized are more stringent than required by current industry codes and standards. The enclosures are constructed of noncombustible materials and have fire and gas detection systems specifically designed for the gas processing industry. The egress requirements of IBC Chapter 10 and the NFP A Life Safety Code requirements are also incorporated into the design. 2.0 PURPOSE This philosophy identifies the design parameters utilized to engineer equipment enclosures that meet the requirements of the IBC for buildings with an H-2 rating but without an automatic sprinkler system. 3.0 SCOPE This document only analyzes those equipment enclosures located at the booster station in Chevron's Piceance Basin Development. It focuses on those enclosures with an H-2 rating by identifying the hazards within the enclosure and the design measures used to mitigate those hazards to personnel who may be present at the time of an incident. 4.0 CONCLUSIONS The parameters utilized in the design and construction of the equipment enclosures covered by this philosophy adequately protect personnel from the hazards due to the presence of hydrocarbons in the enclosure, without employing automatic sprinkler systems. 5.0 RECOMMENDATIONS All enclosures covered by this philosophy should be built and installed as designed. Additionally, operational and maintenance procedures should be implemented to ensure that all safety systems are tested and maintained in accordance with IBC and International Fire Code (IFC) requirements. 6.0 REFERENCE DOCUMENTS Reference Document IBC 2003 IFC 2003 IMC2003 APIRP14C Document Title International Code Council - International Building Code -2003 International Fire Code -2003 International Mechanical Code -2003 American Petroleum Institute- Recommended Practice for Analysis, Design, Installation, and Testing of Basic Surface Safety Systems for Offshore Production Platforms Page4/14 19-'1· · ..• <'·.

The control system is specifically designed to ensure that in the case of a significant event, all instrumentation fails safe, the main electrical feed to the affected area is shut off, incoming hydrocarbon flow to the facility is blocked at the battery limit (boundmy) of the facility, and the bulk of the hydrocarbon inventory in the facility is depressured to the facility's vent system. Although some limited portion of the piping and some vessels within the plant may have a residual gas pressure after the shutdown, virtually all fuel sources within the facility will be immediately shut off. The booster station does not have water available for fire suppression activities. Additionally, no local fire water system exists to provide for tie-in for booster station fire suppression systems. 8.0 FLAMMABLE HYDROCARBON INVENTORY 8.1 Liquid Inventory The primary fire hazard within the enclosures listed in Table I is related to hydrocarbons processed within the facility. In addition to various volumes of natural gas, these buildings will contain various quantities of hydrocarbon condensates (condensates are flammable hydrocarbon liquids that condense out of the gas stream when the gas is exposed to typical ambient temperature and pressure). Page5/14 Title: BOOSTER STATION FffiE PROTECTION PHILOSOPHY Customer: Chevron Mid.continent SBU Project: Piceance Basin Project Spec No: 2033-105-00-ST-0001-01 Date: 23 April 2009 REV:O Page 6 of 14 The hydrocarbon condensate liquid contained in most of the process buildings in Table 1 is a Class lA flammable liquid (its flash point is less than 73°F and its boiling point is less than 100°F). The exempt quantity of Class !A liquids, per the IBC, is 30 gallons. The exempt quantity for flammable gases in the IBC is 1000 standard cubic feet, which is exceeded in each of the building enclosures. Due to the inventory of flammable materials located in each enclosure, a rating of H-2 for each of the enclosures and compressor building is warranted. Fire protection methods based on this occupancy classification are further discussed below. Table 1: Liquid Inventories Enclosure Liquid Volume Liquid Flash Point@ Boiling Point (gallons) OPSIG("F) @OPSIG("F) Booster 253 Condensate -20 34 Compressor 42 Water Building 1 1000 Lubricating 262 >300 oil Building 2 similar 9.0 FACILITY AND ENCLOSURE DESIGN PARAMETERS 9.1 General Almost all of the process building enclosures will contain some amount of hydrocarbon condensate liquid, which is produced from the wellhead along with the lighter natural gas components. Some of the individual unit processes are specifically designed to remove these flammable liquids and transfer them to holding tanks elsewhere within the plant. The volumes of flammable liquids in many of these enclosures exceed the IBC thresholds at which a building is classified as H -2. These volumes may increase the fire hazard within each enclosure to some degree, but do not change the overall philosophy of our proposed fire protection program. 9.2 All flammable liquids and gases within the enclosures are totally contained within the process piping and ASME-rated pressure vessels. An automatic fire and gas detection system is provided to detect any leaks or fires. 9.3 In the event of a fire anywhere within the site, the facility is depressured to the vent to remove the bulk of the flammable gas sources from the fire. Any remaining hydrocarbon liquid would initially be protected and contained within the process piping and/or vessel(s) in which it resides within the enclosure. The rate at which the hydrocarbon liquid would contribute to the ongoing fire would depend upon the amount of damage in the containing piping/vessel(s). If the containment is damaged or breached, the materials would burn in place along with the remaining gaseous components. The relative volumes of gas and liquids being burned, and access to the fire of an oxidizing airflow, would determine the extent to which the liquid boils in place as it contributes to the fire.

The system is designed to contain the fire and allow it to bum out in place. There is no need to attempt to suppress the fire with a water-based sprinkler system. It would likely cause a more substantial hazard by allowing the remaining flammable gases to form a combustible cloud capable of re-ignition until allowed to dissipate. 9.5 It would also be undesirable for the fire department to attempt to put out the fire within an enclosure prior to the consumption of the fuel exposed to the fire. As mentioned above, the remaining gaseous components, along with liquid components that are vaporized due to the heat of the fire, would be dangerous and subject tore-ignition. (See sections 13.3.4 and 13.3.5 for details of this hazard.) 10.0 CONSTRUCTION Each enclosure has the following construction attributes: 10.1 All hazardous gases and liquids within each enclosure are housed in self-contained process piping and/or pressure-rated vessels. Piping is designed and constructed in accordance with ANSI B31.3 requirements for gas facilities of this type. All pressure vessels are designed in accordance with applicable ASME Section VIII requirements for these vessels. 10.2 Process piping and vessels are designed to contain all materials with no significant leakage. A fire and gas detection system is specifically designed for each enclosure to detect the presence of hydrocarbons in the air or a fire event, and will initiate emergency shutdown systems within the plant upon detection of a significant amount of hydrocarbons. (Details of this system are described in the following sections.) 10.3 Each enclosure is constructed entirely of noncombustible materials. 10.4 Additionally, all equipment, piping, instrumentation, junction boxes, panel boards and cable within the enclosure are also noncombustible or flame-retardant. 10.5 Adequate access/egress is provided to allow safe evacuation from the enclosure in the event of a fire or gas release in compliance with IBC and NFP A Life Safety Code requirements. These criteria include the provision of at least two means of egress from any building with travel distance to an exit greater than 25 feet. No dead-end corridors are allowed in any of the buildings greater than 20 feet. 10.6 Ventilation is provided to the enclosure in compliance with IMC requirements. 10.7 Panic door hardware and emergency exit lighting are provided in compliance with IBC. 10.8 To prevent electrical ignition of hydrocarbon vapors, all electrical components on the process skids are explosion-proof and rated for service in Class I, Group D, Division 2 atmospheres as rated by API RP 500, and each component is certified as such by a Nationally Recognized Testing Laboratory (NRTL). A11208V AC and 120V AC wiring and equipment within each process skid are wired to an on-skid explosion-proof panelboard.

Personnel only occupy an enclosure with the doors open when conducting equipment monitoring and observance activities. 10.10 The operational activities typically require personnel in the enclosure for less than 15 minutes on any given day. Any maintenance activities within the facility will be conducted under stringent safety protocols, including additional fire suppression equipment and personnel being present. 10.11 Operational procedures at the plant prohibit the accumulation of any combustible materials within the enclosure. 10.12 The design of the site surrounding each enclosure incorporates a significant barrier zone covered with noncombustible gravel and no vegetation. Additionally, the site has significant security measures in place, and no admittance to the general public is allowed. 10.13 All enclosures and the process control and safety systems that interface with them were designed using Chevron's "Offshore Gulf of Mexico" standards and design criteria. Chevron considers these standards to be more stringent than most onshore standards, leading to a more conservative design. 11.0 FIRE AND GAS DETECTION Each enclosure is equipped with the following fire and gas detection technology, in strict compliance with the IFC and API RP 500: 11.1 Infrared point gas detectors which are tied to a central monitoring system will initiate shutdown of electrical service and hydrocarbon flow to and from the enclosure when gas is detected. These detectors are set to alarm when flammable gas at a concentration of 20% of the lower explosive limit (LEL) is detected. A complete shutdown of power and hydrocarbon flow to the enclosure is initiated when flammable gas at 40% of LEL is detected. All detection and monitoring equipment used at the site is listed by a Nationally Recognized Testing Laboratory (NRTL). See Appendix B. 11.2 A pneumatic fusible loop system consisting of stainless steel tubing pressurized with 40 psig instrument air, and including elements which will melt at 180°F, is provided on all hydrocarbon processing equipment per API RP 500. This system is equipped with a pressure sensor that is tied to a central monitoring system. A loss of pressure in the loop will indicate the affected enclosure and will shut down hydrocarbon flow to and from the enclosure and throughout the facility and will initiate depressurization of the affected facilities to the facility's vent system. See Appendix A. 11.3 "Triple-infrared" fire detectors have been installed in each enclosure, and when a fire is detected, a programmable logic controller (PLC) will shut down the flow of hydrocarbons to and from the enclosure, as well as throughout the facility. The bulk of the hydrocarbon inventories throughout the facility will be depressured to a dedicated flare. (Some minor residual amounts of gas under pressure will still be present in some vessels and piping sections outside of the building enclosures.) Page8/14 Chevron ..

The primary reason for this is that there are no commercially available weatherproof smoke detectors that are rated for Class I, Division 2 service. 12.0 FIRE SUPPRESSION For these process enclosures, the flammable content hazard located within these enclosures is primarily pressurized natural gas. The experience within the petroleum industry is that a typical water-based sprinkler system cannot extinguish a pressurized gas fire, and in fact can create more of a hazard than it mitigates. The standard of the natural gas industry, as codified in API RP 500, is that suppression of a pressurized natural gas fire is best accomplished by immediately shutting off all incoming sources of fuel and venting all other inventories of fuel to a venting or flare system. The remaining non-pressurized gas, along with any associated hydrocarbon liquid, is allowed to bum itself out. For manual suppression of small fires on a limited basis, each enclosure is equipped with hand-held 20-lb Class ABC fire extinguishers located at each door. 13.0 CODE DISCUSSION 13.1 IBC 13.1.1 IBC 2003 normally requires an automatic fire sprinkler system for all H-2 occupancies. 13.1.2 All of the process buildings in this project are classified as H-2 due to the large volume of hazardous materials. 13 .1.3 However, these buildings qualify as exempt from this requirement per IBC 903.3.1.1.1 Exempt Locations. Comments applicable to the facility under discussion are listed parenthetically following the code citation. IBC 903.3.1.1.1. Exempt Locations .... Automatic sprinklers shall not be required in the following rooms or areas where such rooms or areas are protected with an approved automatic fire detection system in accordance with Section 907.2 that will respond to visible or invisible particles of combustion. (In these facilities, an API-compliant gas detection system is installed and designed to respond to concentrations of flammable gas before any combustion takes place.)

Any room where the application of water, or flame and water, constitutes a serious life or fire hazard. (This is true for these facilities. Water sprayed on a pressurized gas fire is unlikely to stop the fire, and could add an explosive hazard due to an unburned gas cloud if it did put out the frre momentarily.) 2. Any room or space where sprinklers are considered undesirable because of the nature of the contents, when approved by the building official. (This is true for these facilities. Because of the nature of the contents - pressurized natural gas -the petroleum industry standard for safety is to mitigate the risk with an API-RP500 compliant gas detection & emergency shutdown system.) 3. Generator or transformer room ... Not Applicable 4. In rooms or areas that are of noncombustible construction with wholly noncombustible contents. (This exemption is partially true of the operating buildings in discussion. The buildings are of noncombustible construction, although the hydrocarbon contents within the process piping and vessels are combustible. However, upon detection of fire, the process equipment is depressured and all flammable gases are vented except for trace amounts remaining in the pipes at atmospheric pressure.) 13 .1.4 IBC Discussion 13.2 IMC In summary, we believe the buildings proposed for the Chevron Booster Station are exactly the type of facility envisioned by the code writers when developing this exemption. There is no question that these facilities contain hazardous flammable materials, but application of a water-based sprinkler system would be counterproductive, and would create more safety hazards than it would solve. A far more desirable solution is the substitution of a fire and gas-hazard detection and emergency shutdown system specifically developed for this industry by the API. With the concurrence of the Building Official and Fire Marshall of Garfield County regarding this exemption, the proposed facilities will be in total compliance with the intent and with the specific language incorporated into the IBC, IFC and related International codes. Each of the process equipment enclosures includes either fixed or manually operable louvers which make the use of non-water sprinkler (gaseous, dry chemical, carbon dioxide, foam, etc.) fire suppression systems problematic. Louvers are provided in compliance with the IMC, which mandates adequate Page 10/14 Title: BOOSTER STATION FIRE PROTECTION PHILOSOPHY Customer: Chevron Midcontinent SBU Project: Piceance Basin Project Spec No: 2033-105-00-ST-0001-01 Date: 23 April 2009 REV:O Page 11 of 14 ventilation for rooms containing hazardous materials. Additionally, standard practice in the gas processing industry is to provide such ventilation to allow flammable gases to disperse, ideally before hazardous accumulations of the gases accumulate within the building. The reasoning within our industry, as codified in API documents, is that ventilating the gas is much safer than trying to contain it within the building and suppress any fires with a non-water based suppression system. 13.3 API The Chevron Booster Station is designed in its entirety to be in total compliance with applicable standards of the American Petroleum Institute. 13.3.1 API RP 500, as detailed above, provides the design standards and details for a gas detection system specifically designed to prevent the accumulation of hazardous levels of flanunable and explosive gases as applicable to our industry. 13.3.2 API RP 14G Section 5.7.d "Automatic Fire Control Systems-Enclosed Machinery Areas" indicates "Gas compressors, hydrocarbon pumps, and generators in adequately ventilated enclosed areas are normally not protected by automatic fire control systems." 13.3.3 API RP14G Section 5.6.c "Manual Fire Control Systems -Enclosed Machinery Areas" recommends dry chemical fire extinguishers and these are provided in each enclosure. 13.3.4 API RP2030 specifically discusses the hazards of attempting to suppress a flammable liquid or gas fire with water in two sections: 6.4 EXTINGUISHMENT .... Extinguishment by water spray is generally most effective where the foe! is a combustible solid, water-soluble liquid or high flash point liquid. However, the risks associated with extinguishing certain fires should be carefully evaluated. If significant quantities of flammable gases or vapors are released a more hazardous condition with potential for explosive re-ignition can be created by extinguishing such fires instead of allowing them to burn at a controlled rate with appropriate surveillance and protection of surrounding equipment. 7 .2.3 Extinguishment. Extinguishment is seldom the primary purpose of water spray system installations in the petroleum industry ... It should be noted that extinguishment of low flash point hydrocarbon liquids with water spray is seldom possible and not necessarily desirable. A key question during hazard analysis is "If the material is extinguished while still generating vapor, is there a risk of vapor cloud re-ignition?" (The answer is yes at this facility.) 13.3.5 API Publication 25JOA is primarily geared towards the Liquefied Petroleum Gas industry, but has relevant information for fighting pressurized gas fires.

One disadvantage of water deluge and water sprays is that they ... may not be effective for jet (torch) fires. Also Section 5.5 Detection Systems gives general guidance on hydrocarbon vapor detectors, heat detectors and flame detectors. This facility includes all three systems, and complies with the guidance of this document. 13.3.6 Fire fighting and suppression standards in the oil and gas industry vary from standard industrial, high rise, and low rise practices. The engineering standards employed in the design of hydrocarbon equipment are conservative and attempt to contain hydrocarbon inventories within the equipment. However, in the event of a leak, the design of the external areas surrounding the equipment are designed to quickly isolate the leak, depressure the equipment, prevent the spread of the hydrocarbon leak, minimize the propagation of any fire event, maintain mechanical integrity through inventory liquidation without catastrophic failure, and minimize exposure to personnel and environment. Chevron SOPs require facility personnel to not engage in fire fighting beyond the incipient stage. The facility and the enclosures have been designed within these parameters.

(Some sections of piping and vessels outside of the building enclosures, may have minor amounts of residual gas under pressure.) 1.3 Each of the enclosures rated for H-2 occupancy will also be equipped with a triple infrared flame detector ("fire eyes") per section 8.3 and pneumatic fusible loop system per section 8.2. 1.4 Because the enclosures are exposed to ambient weather and Class I, Division 2 conditions, and because there are no commercially available weatherproof smoke detectors rated for Class of Service, smoke detection systems will not be installed in this facility. Instead, our design philosophy is to use gas detection to detect the presence of a potentially dangerous atmospheric hazard and, in parallel, to use two different technologies (triple-infrared flame detection and pneumatic fusible heat detection.) We propose the API-RP500 methodology of detecting the gases and shutting down the plant upon detection of dangerous levels of flammable gas.

These facilities include modular facilities close to the gas wellheads, as well as a number of modular unit process facilities at a Central Production Facility (CPF) located north of the town of De Beque, Colorado. Additional facilities are planned for a series of well-head sites, and a booster compression site that collects and compresses gas prior to sending it to the CPF. This document was prepared to address fire protection concerns at the booster station. It is based upon a previous frre protection philosophy document addressing the CPF. Because of the unique nature of fire and explosion hazards at natural gas facilities, Chevron has planned and designed these facilities to incorporate fire prevention and protection systems and procedures in accordance with industry standards, relevant building and frre protection codes, and Chevron's Safety in Design program. The purpose of this document is to present the design and operational philosophy Chevron proposes for the development of these facilities within the booster station. The key design parameter in the design of the fire protection system for the booster station is the ability to quickly and automatically depressure most of the facility, shut down the flow of hydrocarbons to the facility, and remove. all electrical power, except essential power, upon automatic detection of a frre anywhere in the facility. As is typical in the petroleum industry, Chevron has designed the production and treatment facilities at the booster station as a series of modular unit processes. Each module is designed to accomplish some function or functions related to natural gas processing, such as removal of water and solids flowing within the gas stream, removal of heavier hydrocarbons from the gas stream, compression of the gas prior to release to a pipeline, metering the gas prior to delivery of the gas to the pipeline, etc. Because of the harsh weather conditions at the site, many of these unit processes are enclosed to protect certain equipment and instrumentation from the elements. Some of the process skids will be mostly enclosed; other process modules will have an enclosure around the instrumentation and control equipment only. Most of the process enclosures will be factory built, and Chevron has been working with the Colorado Division of Housing to secure plan reviews and permits for these prefabricated facilities. Some of the facilities will be site-built enclosures, including facilities housing the main booster compression equipment at the station. Additionally, some of the prefabricated facilities will house support and utility processes, but will not house any significant hydrocarbon materials. Because of the nature of the fire hazard associated with the enclosures housing process gases and associated equipment, the primary focus of this narrative will be on the two primary process buildings housing the booster compressors. These process equipment enclosures are classified by the International Building Code (IBC) as buildings with an Occupancy Classification of H-2. This rating is based on the amount of flammable gas and liquids carried in the equipment and piping within the enclosures. Although buildings with an H-2 occupancy rating are normally required to have an automatic sprinkler system, Chevron is proposing to protect these facilities with a non-water-based emergency system in accordance with the exemptions allowed in IBC Section 903.3.1.1.1. The design and construction of the process building enclosures have been conducted after identifying and taking into account the hazards associated with the types of equipment and Page3/14 Chevron Title: BOOSTER STATION FIRE PROTECTION PHll.OSOPHY ..

The control system is specifically designed to ensure that in the case of a significant event, all instrumentation fails safe, the main electrical feed to the affected area is shut off, incoming hydrocarbon flow to the facility is blocked at the battery limit (boundary) of the facility, and the bulk of the hydrocarbon inventory in the facility is depressured to the facility's vent system. Although some limited portion of the piping and some vessels within the plant may have a residual gas pressure after the shutdown, virtually all fuel sources within the facility will be immediately shut off. The booster station does not have water available for fire suppression activities. Additionally, no local fire water system exists to provide for tie-in for booster station fire suppression systems. 8.0 FLAMMABLE HYDROCARBON INVENTORY 8.1 Liquid Inventory The primary fire hazard within the enclosures listed in Table 1 is related to hydrocarbons processed within the facility. In addition to various volumes of natural gas, these buildings will contain various quantities of hydrocarbon condensates (condensates are flanunable hydrocarbon liquids that condense out of the gas stream when the gas is exposed to typical ambient temperature and pressure). Page5/14 Title: BOOSTER STATION FIRE PROTECTION PHILOSOPHY Customer: Chevron Midcontinent SBU Project: Piceance Basin Project Spec No: 2033-105-00-ST-0001-01 Date: 23 April2009 REV:O Page 7 of14 9.4 Although a combination liquid-and-gas fire might bum hotter and longer than a pure gas fire, the fundamental principle behind our proposed fire protection system is unchanged. The system is designed to contain the fire and allow it to bum out in place. There is no need to attempt to suppress the fire with a water-based sprinkler system. It would likely cause a more substantial hazard by allowing the remaining flammable gases to form a combustible cloud capable of re-ignition until allowed to dissipate. 9.5 It would also be undesirable for the fire department to attempt to put out the fire within an enclosure prior to the consumption of the fuel exposed to the fire. As mentioned above, the remaining gaseous components, along with liquid components that are vaporized due to the heat of the fire, would be dangerous and subject tore-ignition.

These criteria include the provision of at least two means of egress from any building with travel distance to an exit greater than 25 feet. No dead-end corridors are allowed in any of the buildings greater than 20 feet. 10.6 Ventilation is provided to the enclosure in compliance with IMC requirements. 10.7 Panic door hardware and emergency exit lighting are provided in compliance with IBC. 10.8 To prevent electrical ignition of hydrocarbon vapors, all electrical components on the process skids are explosion-proof and rated for service in Class I, Group D, Division 2 atmospheres as rated by API RP 500, and each component is certified as such by a Nationally Recognized Testing Laboratory (NRTL).

The reasoning within our industry, as codified in API documents, is that ventilating the gas is much safer than trying to contain it within the building and suppress any fires with a non-water based suppression system. 13.3 API The Chevron Booster Station is designed in its entirety to be in total compliance with applicable standards of the American Petroleum Institute. 13.3.1 API RP 500, as detailed above, provides the design standards and details for a gas detection system specifically designed to prevent the accumulation of hazardous levels of flammable and explosive gases as applicable to our industry. 13.3.2 API RP 14G Section 5.7.d "Automatic Fire Control Systems -Enclosed Machinery Areas" indicates "Gas compressors, hydrocarbon pumps, and generators in adequately ventilated enclosed areas are normally not protected by automatic fire control systems." 13.3.3 API RP14G Section 5.6.c "Manual Fire Control Systems -Enclosed Machinery Areas" recommends dry chemical fire extinguishers and these are provided in each enclosure. 13 .3.4 API RP2030 specifically discusses the hazards of attempting to suppress a flammable liquid or gas fire with water in two sections: 6.4 EXTINGUISHMENT .... Extinguishment by water spray is generally most effective where the fuel is a combustible solid, water-soluble liquid or high flash point liquid. However, the risks associated with extinguishing certain fires should be carefully evaluated. If significant quantities of flammable gases or vapors are released a more hazardous condition with potential for explosive re-ignition can be created by extinguishing such fires instead of allowing them to burn at a controlled rate with appropriate surveillance and protection of surrounding equipment. 7 .2.3 Extinguishment. Extinguishment is seldom the primary purpose of water spray system installations in the petroleum industry ... It should be noted that extinguishment of low flash point hydrocarbon liquids with water spray is seldom possible and not necessarily desirable. A key question during hazard analysis is "If the material is extinguished while still generating vapor, is there a risk of vapor cloud re-ignition?" (The answer is yes at this facility.) 13.3.5 API Publication 2510A is primarily geared towards the Liquefied Petroleum Gas industry, but has relevant information for fighting pressurized gas fires.

The gas detection sensor is wired to the facility Emergency Shutdown System (ESS). 1.2 When the gas detector in an equipment enclosure detects the presence of gas at 20% Lower Explosive Limit (LEL), it performs the following functions:. • Indicates on the Human-Machine Interface (HMI) video screens in the Control Room • Indicates on the HMI on the nine (9) outdoor Local Control Panels • Activates a dedicated alarm on the audible alarm system • The 24VDC control system on the skid remains energized, and the skid remains in operation. 1.3 When the gas detector in an enclosure detects the presence of gas at 40% LEL, it performs the rollowing functions: • Indicates on the HMI video screens in the Control Room • Indicates on the HMI on the nine (9) outdoor Local Control Panels • Activates a dedicated alarm on the audible alarm system • Trips off the AC power feed to that enclosure's explosion-proof panelboard at its source in the Electrical Building. • Shuts off all hydrocarbon flow to the enclosure from the source outside of the enclosure • Shutdown valves which shut off hydrocarbon flow are fail-safe, pneumatically operated, and will also close upon safety system failure or loss of air pressure to the fusible loop system. • The 24VDC control system on the skid remains energized, but the skid remains shut off from hydrocarbon flow until the shutdown is manually reset by the Control Room operator. 1.4 The gas detection system shall be tested and recalibrated every 3 months in accordance with 30 CFR Chapter II Part 250.804 "Production safety-system testing and records." The gas detection system that is proposed will be certified by an NRTL to fully comply with this standard and with the system design details contained within API RP 500.

This compressor building is to be registered for operation in Alberta. This report considers only the interior of the compressor building as well as the area outside the building that is hazardous as a result of the building itself. The following area classification is based on both the "Division" (North American) and the "Zone" (IEC) systems of area classification. The latest edition (2006) of the Canadian Electrical Code allows the use of equipment approved under both the existing ''Nmth American" system and the new "IEC" based system. Equipment approved under the North American standards will use the A, B, C and D gas grouping while equipment approved to the IEC based standards will use the IIA, llB and IIC groupings. Hatch Ltd 1 Hatch FES -330360 Exterran -Unit 73012 Area Classification 2 Background -Class I Buildings It has been common practice in the petroleum industry to classifY the interior of buildings in which flammable gases or vapors are handled, processed, or stored as Class I, Division I locations. In many cases this Division 1 classification was derived simply because the facilities were enclosed and it was felt that the concentration of gas or vapor in the building would quickly reach hazardous proportions in the event of a breakdown or failure of equipment. This resulted in electrical installations in these buildings being wired almost exclusively with equipment contained in explosion-proof enclosures and being connected by the use of wire in conduit and/or armored cables, both of which require installation of sealing fittings. The recognition that these explosion-proof wiring systems were frequently improperly installed and/or maintained led to a re-examination of both the area classification and the wiring systems used in Class I hazardous locations. The 2006 Canadian Electrical Code divides Class I hazardous areas into three zones. The defmitions of these zones are: Class I, Zone 0 locations are those areas in which explosive gas atmospheres are present continuously or are present for long periods. Class I, Zone 1 locations are those areas in which explosive gas atmospheres are likely to occur in normal operation. Class I, Zone 2 locations are those areas in which explosive gas atmospheres are not likely to occur in normal operation, and if they do occur, they will exist for a short time; or where flammable volatile liquids, gases or vapors are handled, processed, or used, but in which liquids, gases or vapors are nonnally contained within closed containers or closed systems from which they can escape only as a result of accidental rupture or breakdown of the containers or systems or the abnormal operation of the equipment by which the liquids or gases are handled, processed or used. The following rule of thumb is outlined by API relating the time that flaimnab!e mixtures might occur to the Zone 0, Zone I, and Zone 2 hazardous classifications. Tvpical Relationship Between Zone Classifications and the Presence of Flammable Mixtures Zone 0 I 2 Flammable Mixture Present I OOOor more hours/year (I 0%) 10< hours/year <1000 (0.1%-10%) 10> hour I year (0.1%) Hatch Ltd 2 Hatch FES -330360 Exterran-Unit 73012 Area Classification Facilities classified prior to the adoption of the 1998 Canadian Electrical Code were classified under the divisional system. This system of area classification divided Class I hazardous areas into two divisions. The defmitions of these divisions are: Class I, Division 1 locations are those areas where hazardous concentrations of flammable gases or vapours exist continuously, intermittently, or periodically under normal operating conditions. Class I, Division 2 locations are those areas where flammable volatile liquids, flammable gases, or vapours are handled, processed, or used, but in which the liquids, gases, or vapours are normally confined within closed contaniers or closed systems from which they can escape only as a result of accidental rupture or breakdown of the containers or systems or the abnormal operation of the equipment by which the liquids or gases are handled, processed or used. While flammable gases or vapors exist continuously in most hazardous locations, the concentrations are very low under nonnal operating conditions. · For these gases or vapors to become hazardous, from the perspective of ignition by electrical equipment, they would have to accumulate in concentrations above their lower explosive limit (LEL). For example, facilities processing methane would require concentrations of gas above 5% by volume. This would be equivalent to 100% LEL on the combustible gas detectors permanently mounted in most buildings. The actual operating experience in most enclosed hazardous facilities more closely parallels the defmition for Division 2 than Division 1. In other words, gas or vapor concentrations approaching or above I 00% LEL are rare in most process buildings, and when they do occur they are generally the result of a breakdown or failure of equipment. Most buildings operate with background gas concentrations below 1% LEL. In the early 1990's some users began to use "fugitive emissions" studies to predict the amount of gas or vapor which would be released in a building under normal operating conditions. This would then allow a detennination of the amount of ventilating or make-up air that would be required in the building to continuously dilute these "predicted" emissions to a safe level. The basis for this approach is contained in the API (American Petroleum Institute) document RP500-Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities. RP500 outlines the concept of "adequate ventilation" as a means of ensuring the fugitive emissions in a building are continuously diluted to a safe level. It defines adequate ventilation as "ventilation (natural or artificial) that is sufficient to prevent the accumulation of significant quantities of vapor-air mixtures in concentrations above 25 percent of their lower explosive limit (LEL )". Hatch Ltd 3 Hatch FES-330360 Exterran -Unit 73012 Area Classification It is important to understand that the calculated values of emissions were predictions based on typical data from measurement on facilities. Experience in the field indicated that tl1e predicted values were very likely well above the actual levels encountered in the field. Having calculated fue predicted air make-up volumes, the user was fuen faced with detennining fue actual volume of air which would be entering a building. This was relatively simple where air is forced into a building by mechanical means. What was more difficult was predicting the an10unt of air entering a building by natural means from leakage around doors and windows and other openings in the shell of a building. Generally the natural occurring ventilation was ignored in calculating fue amount of make-up air required: Many facilities were classified Class I, Division 1 witl1 no mechanical ventilation, yet they were not experiencing any significant accumulation of vapors due to fugitive emissions. h1 Western Canada fue cost of heating excessive amounts of cold make-up air can be very high. Therefore there was a need to in1prove our ability to: • accurately predict emission levels, and • accurately calculate or predict the amount of natural ventilation in buildings, or • learn to use the operating experience in our facilities to predict performance in new facilities. Actual operating experience in most buildings in which gases or vapors are handled or processed has been that fuey operate in such a manner tlmt no detectable quantities (i.e. Below l% LEL) of gases or vapors are present under normal operating conditions. h1 many cases these buildings have no continuously operating mechanical ventilation. The natural ventilation in fuese buildings exceeds the requirements for adequate ventilation. Again the problem many designers and operators have faced was the difficulty in accurately dete1mining fue volume of air entering these buildings by natural means, even though they know by observation that the buildings met the defmition of a Class I, Division 2 hazardous location. The NFP A standard 497 (Recommended Practice for Classification of Class I Hazardous (Classified) Locations for Electrical mstallations in Chemical Process Areas) provides guidance in classifying hazardous buildings where this situation is encountered. Paragraph 5.5 .4 of this publication reads as follows: "When classifying buildings, careful evaluation of prior experience with fue same or similar installations should be made. It is not enough to merely identify a potential source of vapor within the building and proceed immediately to defining the extent of a Division I or Division 2 location. Where experience indicates that a pa1ticular design concept is sound, a more hazardous classification for similar installations is not justified. Furthennore, it is conceivable that a location might be reclassified from Hatch Ltd 4 Hatch FES -330360 Exterran-Unit 73012 Area Classification Division 1 to Division 2, or from Division 2 to non-hazardous, based on experience." Using this approach one can conclude that for the purpose of classifying an existing building the observed perfonnance can legitimately be compared to the definitions for Class I, Division 1 or 2 or non-hazardous locations. h1 making this comparison, a rule of thumb of 10 hours per year above the LEL is often used by industry as the dividing line between Division 1 and Division 2 (see table on page 3 of this report). Carrying this one step further, the area classification decisions made for a building based on the observed perfonnance can legitinlately be used for new buildings of sinlilar construction containing similar equipment In performing or revising area classifications of existing buildings, the observed or actual performance (usually based on pennanently mounted gas detector records), supplemented with on-site surveys of the building with portable detectors are usually of more value than fugitive emission studies in determining the proper classification of a building. In this approach, fugitive emissions studies are used more as a means of confirming observed performance than as a prinla1y mea11s of classification. In evaluating the results of the fugitive emissions study it is generally assumed that all metal buildings will leak a mininlum of one air change per hour. Additional openings such as ventilating louvers and ridge vents, even when closed will add significantly to the amount of natural ventilation in the building. Mecha11ical ventilation that is operational at all times while the plant is in operation may also be considered for the purposes of achieving adequate ventilation. While the use of gas detection is useful in the detennining the past perfonnance of a building, the addition of gas detection in itself does not reduce the area classification from Class I, Division 1 to Class I, Division 2. The detennination of a1·ea classification involves both the frequency and duration of the occurrence of flanunable concentrations (above 100% LEL) of gases or vapors. It is possible, in unattended facilities without gas detection, to have flalllmable concentrations of gas present for long periods oftime, certainly more than the 10 hour rule of thumb, without anyone being aware of the situation. Therefore, while gas detection does not by itself reduce the area classification, it can influence the classification by alerting operating persollJlel of an abnormal situation thus reducing the exposure time below the 10 hour rule of thumb. Today most new enclosed hydrocarbon production or processing facilities are being designed as Class I, Division 2 facilities. The wiring systems that a1·e developing are a mixture of traditional Division 2 wiring methods supplemented with equipment that uses Europea11 technology for devices which produce arcs or sparks in their nonnal operation. The move to Division 2 is also allowing much greater flexibility in the use of solid state Hatch Ltd 5 ( Hatch FES -330360 Exterran-Unit 73012 Area Classification devices for monitoring and contra I of processes. Overall, the Division 2 designs are gradually elimiuating the problems the industry has encountered in the past with "explosion proof' enclosures that were necessary in the Division 1 designs. The Division 2 wiring systems now beiug installed are safer, more cost effective and easier to maintain than the Division 1 wiring systems of the past.

(Reference-Skinner Ridge 598-25-3, February 13, 2006) To meet the requirements for Class I, Division 2 (or Zone 2) classifications, it must be demonstrated that this Exterran package will not experience combustible concentrations of gas during "nonnal" operating conditions. It will be shown here that explosive gas atmospheres are prevented in this unit under nonnal operating conditions by the provision of adequate ventilation. It then must also be demonstrated that under abnonnal or failure conditions the compressor package is equipped with the means to prevent flammable accumulations of gas from persisting for more than a "shmt" duration. The accepted (CEC) method of calculating fugitive gas emissions is outlined in Appendix B of the 1997 editions of API RP500-"Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Division 1 and Division 2" and API RP505 - "Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Zone 0, Zone I and Zone 2". The gas emission rates were estimated based on the accepted (CEC) API document #4615 titled, "Emissions Factors for Oil and Gas Production Operations"-1995 edition. Table ES-1, titled, "Average Emission Factors by Facility Type", of the API #4615 document has been used for these calculations. Natural ventilation rates were calculated following the method outlined in section 6.6.2.4.6 of API RP505 -"Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Zone 0, Zone 1 and Zone 2". As shown in the attachments, based on predicted fugitive emissions, the calculated minimum air exchange rate to achieve adequate ventilation for a Hatch Ltd 7 Hatch FES-330360 Exterran-Unit 73012 Area Classification Division 2 (Zone 2) classification in this compressor package is 0.3 air changes per hour. Experience has demonstrated that it is reasonable to assume that metal buildings such as this compressor building will leak a minimum of one air change per hour around doors and windows. This assumption is supported by building suppliers who have agreed it would be difficult to seal a heated metal building such as this to obtain less than one air change per hour by natural means. Openings such as ridge vents and wall louvers will add significantly to the leakage rate even when closed. While the vents, doors and windows will be closed in cold weather, the temperature difference between the building's interior and exterior will be greater, thus increasing the natural ventilation resulting from the "stack effect" inside the building. The Exterran unit 73012 compressor building is equipped with: • One 6' x 7' double man door; • Two 3' x 7' single man doors; • Two 40" x 40" windows; • Two 18" x 32" wall louvers; • One 120" x 120" roll-up door, and • One 12" x 30' ridge vent. The package houses an engine (natural gas fueled) driven reciprocating compressor (Ariel JGT/4, Caterpillar G3516LE-AFRC), suction scrubbers, suction and discharge bottles, blow-down, bypass and recycle valves and other associated valves, fittings, piping, and auxiliary equipment. Natural building ventilation will be achieved through the static wall louvers, ridge vent and by leakage through and around the doors, windows, and all piping penetrations in the walls. There will be a considerable amount of heat in the building generated by the compressor that will assist the natural occmTing ventilation. Cool fresh air will enter the building through the louvers and around the doors, windows, and through other openings in the walls. The cool air will sink to floor level and will flow toward any heat source as it is warmed. At the heat sources the air will rise and exit the building through the ridge vent. The fugitive emission gas in the building will be lighter than air and will be carried out of the building with the rising air current. Given our experience with similar compressor packages and the safety factors in the API calculations, it is expected that the natural occurring ventilation rate in this building will be in excess of the minimum requirement to achieve adequate ventilation. All areas of the building interior will be adequately ventilated and no pockets of stagnant air are expected. It is therefore concluded that the interior of tl1is compressor building will be adequately ventilated by natural means. Hatch Ltd 8 Hatch FES -330360 Exterran-Unit 73012 Area Classification Although it has been established above that the compressor package interior will not experience explosive gas atmospheres under normal operating conditions due to the provision of adequate ventilation, flammable concentrations of gas could occur as a result of equipment failure. While such occurrences would be rare, a Division 2 (or Zone 2) area classification requires that when these situations do occur, they be corrected within a short period. The industry accepted definition of "short duration" as outlined in API RP 505 is 10 hours per year. In order to ensure prompt detection of a gas release, it is recommended that a combustible gas detection system be permanently installed in this compressor building to shutdown the process and to assist operations personnel in taking quick corrective action. The compressor building interior would then meet all the requirements for a Division 2 (Zone 2) classification. · · Hatch Ltd 9 Hatch FES -330360 Exterran -Unit 73012 Area Classification 4 Conclusions and Recommendations The appropriate area classification of the Exterran Unit 73012 is Class I, Division 2 (or Zone 2), Group D or DA. Equipment with a maximum surface operating temperature up to 482°C (the ignition temperature of natural gas) or with a Tl or lower surface temperature code will be suitable for use in the compressor building. The extent of the Class I, Division 2 (or Zone 2) hazardous area outside the compressor building is based on the area that would be affected by an abnormal situation such as a large release of gas or vapor inside. Such gases would leak out of the building through the louvers, ridge vent and around the doors and other penetrations in the building shell. Note that the process gas stream being typical natural gas would have a vapor density of about 0. 70, and being lighter than air will tend to rise. Therefore, the area for 3 meters in all directions outside the compressor building will also be classified as Class I, Division 2 (or Zone 2). The classification assigned to the interior of the Exterran Unit 73012 is subject to the following conditions. If any of these conditions are not met, the area classification in this report will not apply and the classification of the interior of the compressor building will revert to Class I, Division 1 (or Zone 1) in accordance witb. the latest edition of the Safety Codes Council "Code for Electrical Installations at Oil and Gas Facilities". 1. The compressor building must not infringe on any Division 1 (Zone 0 or Zone 1) area created by other equipment at the site of application. 2. The natural ventilation devices (ridge vent and wall louvers) may be shut, but may not be closed off or removed. If changes are required to the compressor building that will reduce the ventilation, the effect of the changes on the concentration of fugitive emissions must be evaluated. 3.Any deviations from the design of this specific compressor package with respect to the building's volume or piping, valves and fittings as shown in the drawings listed, must be evaluated for their effect on the concentration of fugitive emissions in the compressor building. 4.0perating procedures and controls must be in place to ensure abnonnal situations resulting in combustible concentrations of gas do not persist for more than I 0 hours per year in the compressor building. 5. The compressor building must be maintained in a mrumer that will ensure significant levels of combustible gas (above I - 5 % of the LEL) do not exist under normal operating conditions.

Combustible gas detection system is permanently installed and maintained in accordance with the manufacturer's recommendations or in accordance with ANSI/ISA Recommended Practice 12.13, Part II, Installation Operation and Maintenance of Combustible Gas Detection Instruments. 7. The design of this compressor bujlding is based on use with Group D or IIA gases. Use with gases in other gas groups or gases above acceptable levels (i.e.: H2S > 25% mole fraction) will require review of the installed electrical equipment and replacement of any devices not suitable for the other gas groups. 8.
