Valerus--Hunter Mesa Compressor Station Oclober5,2010 Spill Prevention, Control and Countermeasure Plan SECTION 1.0 INTRODUCTION The Oil Pollution Prevention Regulations establish procedures,
methods, equipment and other requirements to prevent a discharge of oil from non-transportation related facilities into or onto navigable waters of the United States. Spill Prevention,
Control, and Countermeasure (hereafter "SPCC Plan" or "Plan") Plans for facilities are prepared and implemented as required by U.S. Environmental Protection Agency (U.S. EPA) regulations
as promulgated in Title 40, Code of Federal Regulations, Part 112 (40 CFR 112). A non-transportation related facility is subject to SPCC regulations if: I) due to its location, the facility
could reasonably be expected to discharge oil into or upon the navigable waters of the United States; 2) the total aboveground storage capacity exceeds 1,320 gallons (calculated total
of containers with capacity of 55 gallons or more); or 3) the completely buried storage capacity exceeds 42,000 gallons 1 As stipulated by 40 CFR 112.3(b), the requirement to prepare
and implement the SPCC Plan will be fulfilled to ensure compliance with this part before operations commence. Valerus Compression Services, LP (Valerus) has prepared and will implement
and maintain this on-shore production facility SPCC Plan according to all appropriate regulations as the facility possesses an aboveground storage capacity greater than 1,320 gallons.
The collective potential maximum capacity of this facility is approximately 50,400 gallons and individual storage volumes up to 16,800 gallons each. Any additional oil storage containers
will be added to the plan at As aforementioned, due to the storage capacity of the Hunter Mesa Compressor Station (HMCS), Valerus is required to develop, implement and maintain an SPCC
plan for this facility. The HMCS SPCC Plan (Plan) has been prepared in accordance with 40 CFR 112.7 and 112.9. The Plan has been prepared in writing; all site-specific facility data
are stored and managed within an electronic database. The purpose of the Plan is to identify sources of oil and develop and outline procedures to prevent the release of oil into navigable
waters of the United States. This Plan identifies equipment, workforce, procedures and steps to prevent, control and provide adequate countermeasures to a discharge. The SPCC Plan is
not required to be filed with U.S. EPA, but a copy must be available for onsite review by the Regional Administrator (RA) during normal working hours, if the subject facility is attended
at least four (4) hours a day. The SPCC Plan must be submitted to the U.S. J Completely buried tanks subject to all of the technical requirements of 40 CFR Parts 280 and 281 are not
subject to inclusion during the calculation of the 42,OOO-gallon threshold. The spec Plan shall be amended within six (6) months whenever there is a change in facility design, construction,
operation, or maintenance that materially affects the facility's discharge potential. Additionally, the Plan must be reviewed once every five (5) years and amended to include more effective
prevention and control technology, if such technology will significantly reduce the likelihood of a discharge event and has been proven in the field. All technical amendments must be
certified by a registered Professional Engineer. 2 NOAA Atlas 2, I 973."Westem U.S. Precipitation Frequency Maps", WestemRegionai Climate Center, Reno, Nevada.

Facility Information 2.6.1 General Facility Iuformation [40 CFR 112.7) Name and type offacility: The HMCS is considered a production facility with the primary and sole function of natural
gas compression. As related to the determination of applicability, the production facility is located upstream of associated custody transfer points to transportation-related systems.
The facility is owned and operated by Valerus. The HMCS services a gathering system managed by Antero Resources Corporation (A,ntero). The initial date of operation for the facility
is anticipated to be no sooner than March 15,2011 Location of facility: The location and general area description of the HMCS is within SWv., Sec 30, T6S R92W, 6th Principal Meridian,
near the city of Rifle, Colorado, on private property. The adjacent properties and area surrounding the facility is considered multiple-use land in which the general and typical activities
include oil and gas exploration and production, farming and ranching. Refer to Figure I: Topographic Vicinity and Field Location Map, for a United States Geological Survey (USGS) topographic
map of the facility or; Figure 2: Aerial Vicinity and Field Location Map and for a general location map, which are located in Appendix A. The city of Rifle, Colorado is the nearest population
center. The HMCS can be reached by taking 1-70 to Exit 90 (Rifle, CO). Travel south to the southernmost roundabout and travel east on Airport Road/County Road 346 approximately 2.5 miles.
Turn right (south) on Hunter Mesa Road/County Road 333. Travel approximately 2 miles. The compressor station is located on the left hand side (North) of the road. 9
Valerus--Hunter Mesa Compressor Station October5, 2010 Spill Prevention, Control and Countermeasure Plan According to the U.S. Geological Survey topographic quadrangle map identified
as Hunter Mesa, the facility lies at an approximate elevation of 5800 feet above mean sea level. The relief of the area is shallow in the immediate vicinity and to the South of the site;
however, when heading north the relief varies moderately. Vegetation in the immediate vicinity of the site is a mixture of the pinyon-juniper community and low desert species. Specifically,
the native vegetation in the immediate and surrounding area is comprised of several species including Sagebrush (Artemisia, sp), Rubber Rabbitbrush, (Chrysothamnus, nauseosus), and Indian
Ricegrass (Oryzopsis hymenoides). Cheatgrass (Bromus tectorum) and Russian thistle (Salsola iberica) were species observed which are considered noxious and/or exotic invasive. General
surface topography is relatively flat with slopes varying from 2-5 degrees with a north-west aspect. To the west of the facility is a troughed area similar to an ephemeral drainage;
ultimately the troughed area drains to a flat vegetated area on top of the associated plateau. There was no indication that there is a path for water flows from the compressor .station
to surrounding tributaries to the Colorado River. As derived from information provided by the United States Department of Agriculture Natural Resources Conservation Service (USDA NRCS),
soils in the immediate area of the HMCS are identified as Potts loam, 3 to 6 percent slopes (map unit symbol 55). The HMCS is considered a production facility as the purpose and function
of the facility is to compress the natural gas, one of several steps in the production process. The facility site consists of a level earthen pad containing gas production equipment
that may include the following: • Metering equipment; • Above ground storage tanks [Produced water tank(s) and Condensate tank(s)]; • Unloading/loading area(s); • Piping systems (Buried
and aboveground); • Dehydration unites); • Separator(s); and • Processing Equipment. • Pipeline Slug Catchers The physical layout of the facility site is noted on the Facility Plot and
Drainage Diagrams that are enclosed in Appendix A, Figure 3. 2.6.2 Location of SPCC Plan [40 CFR 112.3(e)] The natural gas production/compression facility covered by this Plan is not
continually manned by operations personnel but operates 24-hours per day. The original Plan will be maintained in the Valerus Houston, TX office. A copy will be stored in a weather 10
Valerus--Hunter Mesa Compressor Station October5,20l0 Spill Prevention, Control and Countermeasure Plan protected building at the HMCS facility. A copy shall be made available for on-site
review or inspection by the EPA Regional Administrator during regular business hours. 2,7 Owner and Operator Contacts [40CFR 112.7] Name and address of owner/operator: Valerus Compression

Process Descriptions [40 CFR 112.7 (a)] 2.8.1 Hnnter Mesa Compressor Station The HMCS is a natural gas compression facility and is one of several integral parts of natural gas production
and transport. The function and importance is described as follows: The pipeline transporting the gas must be highly pressurized to accomplish the goal of intra and interstate transport
to the end user, To ensure that the natural gas flowing through anyone pipeline remains pressurized, compression of this natural gas is required periodically along the pipe, This task
is accomplished through the use of compressor stations, usually placed at 40 to 100 mile intervals along the pipeline. The natural gas enters the compressor station, where it is mechanically
compressed. In addition to compression, stations usually contain some type of liquid separator, much like the ones used to dehydrate natural gas during its processing. Usually, these
separators consist of scrubbers and filters that capture any liquids or other undesirable particles from the natural gas in the pipeline. Although natural gas in pipelines is considered
'dry' gas, it is not uncommon for a certain amount of water and hydrocarbons to condense out of the gas stream while in transit. The liquid separators at compressor stations ensure that
the natural gas in the pipeline is as pure as possible, and usually filters the gas prior to compression. 2.9 Facility Storage [40 CFR 112.7(a)(3)(i)] Oil, as defined in 40 CFR 112,2,
is stored in an above-ground storage tank (AST) located on-site at each facility. Oil-filled equipment are not considered containers as defined by 112.2 and therefore not considered
in overall calculations. An inventory of the materials at the facility that are regulated under this SPCC Plan is presented in Table I in Appendix B, The total oil 11
Valerus--Hunter Mesa Compressor Station October5,20l0 Spill Prevention, Control and Countermeasure Plan aggregate of oil or petroleum products in aboveground storage tanks is 50,400
gallons. All tank(s) and storage unites) locations are as indicated on Figure 3 in Appendix A. 2.10 Facility Drainage and Distance to Navigable Waters The closest water body to the HMCS
is Mamm Creek and an unnamed tributary thereof, The mentioned unnamed ephemeral stream is adjacent to the east of the facility and is tributary of the Colorado River. Topographic contour
lines on Figure I indicate the estimated general direction of storm water flow for the facility. Table 2 lists specific distances and directions. Table 2: Hunter Mesa Compressor Station,

in which the failure occurred; • Additional preventive measures taken or Planned to minimize the possibility of recurrence; and • Such other information as the Regional Administrator
may reasonably require pertinent to the SPCC Plan or discharge. In accordance with 40 CFR 112.4(c), the information listed above shall also be provided to the appropriate state oil pollution
control agency. In Colorado the appropriate agency is the Colorado Oil and Gas Conservation Commission (COGCC). 3.2 Amendment of Plan by the Regional Administrator [40 CFR 112.4(d))
The Regional Administrator may deem that the Plan does not meet the requirements of this part or the necessity to further prevent and contain discharges from the facility requiring amendment
of the Plan. 13
Valerus--Hunter Mesa Compressor Station October5,2010 Spill Prevention, Control and Countermeasure Plan SECTION 4.0 FACILITY CONFORMANCE WITH SPCC REGULATIONS [40 CFR 112.7(a)] 4.1 Facility
Conformance, Definition and Requirements [40 CFR 112.7(a)(3)] The facility conforms to all applicable requirements of 40 CFR 112 as detailed in the subsequent sections of this spec Plan.
Specifically, the facility is defined as an onshore oil production facility, and is therefore subject to 40 CFR 112.9. In addressing the requirements of this rule, and by providing additional
information in the tables and figures included in this spec Plan, the facility information required by 40 CFR 112.7(a)(3) is provided in this spec Plan. 4.1.1 Oil Storage Capacity [40
CFR 112.7(a)(3)(i)] According to the aforementioned definition and applicability determination in section 2.10 of this Plan, oil-filled equipment are within the scope of the spec rule
and as such will be addressed regarding storage capacity and the prevention of discharges from such equipment. A list of the oil storage containers, container capacity, and construction
material and type of oil stored in each container is included in Table 1 of Appendix B. The total maximum throughput is also included in Table 4 in lieu of a production rate. 14

Valerus--Hunter Mesa Compressor Station OClober5. 2010 Spill Prevention, Control and Countermeasure Plan SECTION 6.0 SPILL PREVENTION METHODS 6.1 Diversionary Structures and Containment
[40 CFR 112.7(c)] A description of secondary containment and/or diversionary structures or equipment for each storage unit or potential oil discharge point at the facility is included
in Table I of Appendix 8. Table I includes a description of the type of containment and material of construction. Containment capacity calculations and/or specifications are provided
in Table 3 of Appendix 8. Each secondary containment system is capable of containing oil and has been constructed so that any discharge from a primary containment system (such as a tank
or pipe) will be cleaned-up within 72 hours before any escape of oil occurs. 6.1.1 Oil Production Facility Drainage [40 CFR 112.9(b)] Secondary containments utilized at the HMCS are
not equipped with drainage valves. Accumulated precipitation is generally allowed to evaporate, pending an inspection by the Field Technician or the pumper/gauger to ensure there is
no visible sheen. If oil is noted on the accumulated precipitation it will be removed prior to draining the containment. If a containment must be drained, a vacuum truck is generally
used and the contents are either reincorporated back into the system or are taken to an appropriate and approved disposal facility. Recovered product is to be placed back into the appropriate
storage container. All secondary containment drainage events shall be recorded on the Secondary Containment Drainage Log (Appendix D). Facility drainage at the HMCS, but outside secondary
containments are ofthe "enclosed" type. All process effluents, treated or untreated, are routed through drain lines to storage tanks and are disallowed to be released off-site. Storm
water ditches are visually examined by facility personnel during routine facility rounds, during formal inspections, and after precipitation events, to detect any discoloration or staining
that would indicate the presence of oil from small leaks within or on the facility. See the facilities Storm Water Management Plan for inspection frequency and procedures. Any accumulation
of oil is promptly removed and returned to an appropriate storage container. 6.1.2 Bulk Storage Containers [40 CFR 112.9(c)] I. Oil storage containers have been designed and installed
in accordance with good engineering practices. The construction and tank materials are compatible with the material stored and conditions of storage. Container capacity is adequate to
assure the tank will not overflow in the event that the pumper/gauger is delayed in making regularly scheduled rounds. Specific storage container and secondary containment details are
presented in Sections 6.1.3 through 6.1.7 and in Tables I and 3 in Appendix 8. 16
Valerus--Hunter Mesa Compressor Station Oclober5,2010 Spill Prevention, Control and Countermeasure Plan 2. Oil storage containers are enclosed within secondary containment structures,
The containment capacity exceeds the SPCC requirements providing secondary containment sufficient for the size of the largest tank, plus freeboard to contain precipitation. This secondary
containment capacity is a minimum 110 percent of the capacity of the largest tank within the containment area (e.g. 400 barrel condensate/produced water tank). The amount of freeboard
within secondary containment also exceeds the amount of precipitation anticipated at this facility, which is estimated to average, 2.1 inches of precipitation based on the 25-year, 24-hour
storm event for Rifle, Colorad02• Details of the secondary containment capacity calculation are provided in Table 3, Appendix B. 6.1.3 Secondary Containment [40 CFR 112.7(c)) Secondary
containment requirements for oil storage containers used at the HMCS are discussed in Section 6.1.2. Other oil-filled operational equipment and other process equipment that is not within
secondary containment has no potential for significant release into navigable waters of the United States as described in Table 2. Oil filled operational equipment and other process
equipment will be inspected in accordance with Section 6.1.11. Any additions to the HMCS will be evaluated for secondary containment requirements and added to the Plan in accordance
with Section 2.1.1 6.1.4 Practicability of Secondary Containment [40 CFR 112.7{d)) Secondary containment requirements for oil storage containers used at the HMCS are discussed in Section
6.1.2. All bulk oil storage containers are in secondary containment. Nonetheless, an Oil Spill Contingency Plan has been provided as Attachment H-I of Appendix H to ensure that an incident
does not result in a release of oil into navigable waters ofthe United States. Other measures listed under 40 CFR 112.7(c) such as the use of sorbents are also a mean of secondary containment.
6.1.5 Contingency Plan [40 CFR 112.7(d)) Valerus has complied with requirements of the SPCC regulation, therefore a Contingency Plan is not required; however, one has been included as
these measures are already in place. This document is provided as Attachment H-I of Appendix H of this Plan. 2 NOAA Atlas 2, 1973."Westem U.S. Precipitation Frequency Maps", Western

Valerus--Hunter Mesa Compressor Station October5,2010 Spill Prevention, Control and Countermeasure Plan 6.1.6 Tank Container and Content Compatibility [40 CFR 112.9(c)] Materials used
for all storage tanks are compatible with the material stored and the conditions of storage. No container will be used at the facility for the storage of oil unless its material and
construction are compatible with the material being stored and the conditions of storage such as pressure and temperature. 6.1.7 Periodic Tank Inspection: A Field Technician (or designee)
will conduct a monthly visual deficiency inspection of the oil storage vessels identified in Table 1, Appendix B of this Plan. The inspections will be documented using the Field Technician
Log fonn provided in Appendix F. The monthly inspections include a visual inspection of exterior surfaces for leaks and other deficiencies of the vessel, supports, foundations, connected
piping and valves and secondary containment. If an inspection reveals a leak or equipment deficiency outside of normal operating conditions, corrective action shall be taken promptly
to eliminate the leak or deficiency. Specific items listed below will be inspected: 1. Visually inspect exterior surfaces of storage vessels and oil-filled equipment and associated pipes,
valves, and other appurtenances and identify any leaks, cracks, area of wear, external wall thinning, swelling, excessive corrosion or mechanical deficiency. 2. Visually inspect vessel/equipment
supports and secondary containment structures for excessive settlement, apparent structural weakness, cracks or other deficiency that would allow the secondary containment to leak. 3.
Inspect and monitor existing leak detection systems (Le., observation ports on double-bottom tanks), and other warning systems such as alarms and level gauges. If, during the monthly
inspection the inspector observes a spill of oil from any of the equipment, the inspector shall immediately initiate the oil spill response procedures outlined in this spec Plan. Discharge
prevention featnres: Each storage tank has a system in place that has been designed and installed in accordance with good engineering practice to prevent discharges. Secondary containment
systems, including walls and floor of the respective system, is capable of containing oil and has been constructed so that any discharge will not infiltrate permeate, drain, or otherwise
escape before cleanup may occur. Features include: adequate container volume to avoid overfill and emergency venting. All discharge prevention features are inspected 18
Valerus--Hunter Mesa Compressor Station October5,2010 Spill Prevention, Control and Countermeasure Plan at regular intervals with the tank inspections. Any secondary containment deficiencies
will be corrected as soon as possible. Visible oil leak corrections from tank seams and gaskets: On-site personnel immediately repair any visible oil leaks at the facility. Any spilled
oil is cleaned up immediately using on-site spill response equipment and supplies. 6.1.8 Disposal of Recovered Materials [40 CFR 112.7(a)(3)] Contaminated material that is recovered
during cleanup efforts will be disposed in accordance with all applicable regulations. Recovered products shall be placed in a suitable product storage vessel. Produced water shall be
placed back into a produced water storage vessel, or transported off site for disposal. Oil-contaminated materials recovered during a spill event will be appropriately containerized,
or will be remediated on site in accordance with the Bureau of Land Management (BLM) and COGCC stipulations. Soils and other solids will be placed in 55-gallon drums or roll-off containers
or other approved containers. Recovered materials will be labeled, characterized and disposed in accordance with all applicable regulations or as directed. 6.1.9 Facility Transfer Operations,
Onshore Oil Facility [40 CFR 112.9(d)] Aboveground valve and pipeline examination: All aboveground valves and pipelines are routinely inspected as described in Section 6.1.11 of this
Plan. Valves and piping are inspected for the general condition of flange joints, expansion joints, valve glands and bodies, drip pans, pipe supports, locking of valves, and metal surfaces.
Integrity or leak testing is also performed at the time of any installation, modification, construction, relocation, or replacement of buried piping. Flow line maintenance 40CFR 112.9(d)(3)
: The following procedures and protocols are in place to maintain all flow lines in order to prevent discharges from flow lines. Field personnel and pumper/gaugers visually observe flow
lines during regularly scheduled rounds. Most buried piping at the facility is protected by coating or wrapping. Any buried equipment within the facility will be visually inspected for
corrosion whenever exposed through excavation. Further inspection and correction will be conducted on the affected metal equipment, if problems are identified, to minimize the chance
for discharge from facility transfer equipment. When a pipe is not in service, or is in a standby service for an extended period of time, the associated valves are kept closed and locked
and lines are ball-plugged or blindflanged and marked as to their tie-in connection. 19
Valerus--Hunter Mesa Compressor Station October5,2010 Spill Prevention, Control and Countermeasure Plan 6.1.10 Facility Loading/Unloading Operations [40 CFR 112.7(h)] Loading/unloading
procedures meet DOT regulations: All tank truck drivers are required to comply with Department of Transportation (DOT) regulations in 49 CFR Part 177 and facility standard operating
procedures. All drivers must be authorized and/or certified by Valerus to load or unload product at the facility. Valerus requires truck drivers to use the following procedures: I. Follow
allloadinglunloading procedures required by DOT regulations. 2. Ensure that communication off site is available via cell phone or radio in the event of an emergency. 3. Verify the location
and adequate inventory of emergency spill response equipment. 4. No driver is allowed to leave the visual site of the connection during loading/unloading operations, i.e., the driver
will monitor the transfer process at all times. 5. Prior to filling and departure of any tank car or truck, the transport driver will inspect their fitting and valves for leaks or discharges.
6. Drivers will assure that all drains, outlets, fittings, etc. are tightened, adjusted or replaced to prevent liquid discharge while in transit. Secondary containment for vehicles:
The loading/unloading area will be maintained with spill response absorbent booms and socks designed to handle such discharges. In addition, facility personnel will be available to observe
all off-loading activities at the facility. The absorbent booms and socks are designed to hold at least the maximum capacity of any single compartment of a tank car or tank truck loaded
or unloaded at the facility. A spill response kit is recommended to be equipped on all vehicles performing loadinglunloading procedures. 6.1.11 Inspections and Record Keeping [40 CFR
112.7(e)] Secondary containment areas will be inspected after abnormally heavy precipitation events. Excess precipitation, determined not to be impacted by oil (i.e. visible sheen),
will be allowed to evaporate. Levels will be monitored and excess water removed to prevent overflow per Section 6.1.1. At regular intervals during facility operation, personnel tour
the facility and visually inspect ASTs, piping, and valves for obvious signs of potential leaks. In addition to the shift tours, a documented inspection of the facility is performed
at least annually. Tank integrity testing is performed on a regular schedule, and when material repairs are performed, using non-destructive test methods. Mechanical Integrity Testing
(MIT) is performed annually on all: 20
Valerus--Hunter Mesa Compressor Station Spill Prevention, Control and Countermeasure Plan transfer lines; valves; and discharge prevention and fail-safe filling features. Infonnation
collected during the inspections may include: wall thickness; pressure rating; relief valve set pressure; design criteria; October5,. 2010 overall condition of the tanks, pipe supports,
tank foundations, tank valves, lines, back pressure regulators, and other appurtenances; condition of protective coatings; and assessment of corrosion protection. Inspection records
are filed with this SPCC Plan at the Valerus Houston, TX office for a minimum of 3 years. Signed and dated records of all inspections and other pertinent information, such as spills,
removal and disposal of spill contaminated materials, replacement or repair of equipment, and training are maintained for a minimum of 3 years. 6.1.12 Personnel Training, and Spill Prevention
Procedures [40 CFR 112.7(1)(1)(3)] The oil-handling personnel operating the facility are instructed on job responsibilities and duties. They are under the direct supervision of the facility
Maintenance and Operations Foreman, who is responsible for establishing performance and duty guidelines. Regular safety meetings are held to discuss a variety of safety procedures and
other pertinent job responsibility criteria. A written record of all training is maintained for 3 years. Training includes: Instruction on the safe and efficient operation and maintenance
of equipment to prevent spills; Discharge prevention protocols; Applicable pollution control laws, rules, and regulations; General facility operations; Discussion of the SPCC Plan, spill
prevention and cleanup methods; and Instruction in proper inspection techniques, regulations, record keeping and inventory control procedures. Emergency Procedures 21
Valerus--Hunter Mesa Compressor Station October5,2010 Spill Prevention, Control and Countermeasure Plan The person who is designated to oversee safety or maintain the facility is the
primary· person accountable for spill prevention. This position is staffed by a qualified and competent person. Refer to Section 2.7 for contact information. Spill prevention briefings:
Spill prevention briefings are held at least once a year during regularly scheduled safety meetings. These briefings will be held to assure adequate understanding of the SPCC Plan for
the facility and will highlight and describe known discharges as explained in 40 CFR 112.l(b) or failures, malfunctioning components, and any recently developed precautionary measures.
Additional briefings will be held if any "near misses" or incidents are noted during the previous month. Sign-in sheets, which include a list of the topics discussed at the briefing,
are maintained for documentation. A Briefings and SPCC Training Log is included as Attachment G-2 of Appendix G. Facility Security [40 CFR 112,7(g)) Onshore production facilities are
excluded from the requirements of this subsection. However, the facility is located in a rural area, and the site is fenced and illuminated. General security is performed and controlled
by operations personnel during daily activities. Additionally, flow valves are generally locked and sealed to preclude tampering. The facility also has adequate and appropriate lighting
for nighttime operations at the facility. Brittle Fracture Analysis [40 CFR 112.7(i)) The facility does not currently have nor are there any plans for field-constructed aboveground oil-storage
containers which would be subject to SPCC rule and therefore require inclusion in this Plan. This section of the regulation is therefore not applicable to the facility. Applicable Requirements
[40 CFR 112.7(j)) Detailed discussions of conformance with the applicable requirements of 40 CFR 112, and other effective discharge prevention and spill response procedures used at the
facility are provided in Sections 4, 6 and 7 of this Plan. 22
Valerus--Hunter Mesa Compressor Station October 5, 2010 Spill Prevention, Control and Countermeasure Plan SECTION 7.0 OIL SPILL RESPONSE PROCEDURES 7.1 Response Management Structure
The Response Coordinator (RC) and Alternate Response Coordinator(s) (ARC) are responsible for implementing response procedures in the event of an oil spill or discharge emergency, These
personnel have the authority to commit the resources necessary to carry out a response. However, all operating personnel of Valerus and Antero receive training to familiarize themselves
with all aspects of the SPCC Plan, facility operations, the location and characteristics of materials handled at the facility, the locations of all records within the facility; and are
responsible for proper implementation of response procedures should the RC or ARC be unavailable. 7.2 Initial Response Any release at the HMCS will be discovered through observations
made during normal work activities, inspections of work areas and equipment. Upon discovery of a release the first step of the response is to ensure personal safety, the individual discovering
the release will: I. Protect themselves with personal protective equipment (PPE); 2. Ensure personal safety and the safety of others. If the area is unsafe, retreat to a safe position
and call emergency responders via cell phone or relay information to dispatch via radio. If the situation is safe, proceed to step 3. 3. Report the release to the appropriate management
official. 4. Eliminate ignition sources; 5. Restrict access; 6. Stop the source of the release if safely possible using available resources (spill response kits); 7. Assess the basic
situation; 8. Contain the spill if possible to safely to so; 9. Report the release to the appropriate authorities listed in Section 8.0. 10.lf the spill involves a minor amount of oil,
it will be cleaned up by Valerus personnel provided that: a. They have current 40-hr HAZWOPER and applicable OSHA training; b. Appropriate Material Safety Data Sheets (MSDS sheets) are
available for the material spilled; and c. Appropriate PPE is available and used. 7.3 Internal Reporting Requirements Spills/releases of produced liquids (i.e. condensate, produced water
and/or condensate drip) or any refined hydrocarbon product will be reported to the EH&S Department using the internal SpilllRelease Notification Form provided as Attachment E-I of Appendix
E. A written report will be submitted via e-mail or by fax. This report shall be completed as 23
Valerus--Hunter Mesa Compressor Station October5, 2010 Spill Prevention, Control and Countermeasure Plan soon as practicable after a spill event and submitted electronically to the EH&S
Department 7.4 Oil Spill Emergency Reporting 7.4.1 United States Environmental Protection Agency If the release constitutes a discharge as defined in 40 CFR 112, I (b) of the SPCC regulation,
it is considered an Oil Spill Emergency, That is if the release is into or upon navigable waters of the United States, if the release impacts surface water quality by causing sheen,
film or discoloration of the water surface and/or causes a sludge or emulsion to be deposited beneath the water surface or adjoining shoreline, 7.4.2 State of Colorado Colorado Oil and
Gas Conservation Commission Spills and/or releases of produced fluids exceeding 5 barrels, including those contained within a containment structure shall be reported on COGCC SpilllRelease
Form 19 (copy included as Attachment E-2 of Appendix E), The report shall include information relating to the initial mitigation, site investigation and remediation. The report shall
be submitted to the COGCC Director within 10 days of discovery of the release. Spills and releases of produced fluids shall be controlled and contained immediately upon discovery. Impacts
resulting from a spill/release shall be investigated and cleaned up as soon as practicable, Additional activities may be required if the spill/release threatens or causes significant
adverse environmental impacts to air, water, soil, or biological resources, or to the extent necessary to ensure compliance with the allowable concentrations included in Table 910-1
of the Colorado Oil and Gas Rules and Regulations (see Attachment E-3 of Appendix E). When threatened or significant adverse environmental impacts any air, water, soil, or biological
resources is caused, operators may be required to submit a Site Investigation and Remediation Work Plan Form 27 (copy included as Attachment E-4 of Appendix E). Colorado Department of
Public Health and Environment (CDPHE) If a spill reaches Waters of the State (including surface water, ground water and dry drainage conveyances leading to surface water), the incident
must be reported immediately to CDPHE. Refined petroleum releases must be reported, if they have entered navigable waters, and/or if the quantity exceeds 25 gallons. 7.4.3 Bureau of

Attachment F-I Procedures SPCC Plan Name: Valerus--Hunter Mesa Compressor Station Written Procedures Approved By: Signature Title Name (please print) Date 1.0 Responsibilities These
procedures establish the requirements for periodic inspections and tests for the oil storage vessels and oil-filled equipment for the Valerus--Hunter Mesa Compressor Station (HMCS) to
minimize the risk of a spill incident. The Field Technician is responsible for the implementation of these procedures. Specifically, the Field Technician is responsible for conducting
the inspections; and making certain that remediation or repair work is properly prioritized and completed in a timely manner. The Field Technician may designate another personnel member
to complete the inspections. Designated personnel will have the authority to commit the resources necessary to carry out a response, if warranted and will receive training to familiarize
themselves with all aspects of the SPCC Plan, facility operations, the location and characteristics of materials handled at the facility, and the location of pertinent records within
the facility. 2.0 Procedures The Field Technician (or designee) will conduct a monthly visual deficiency inspection of the oil storage vessels and oil-filled equipment identified in
Table I of Appendix B within the SPCC plan. The inspections will be documented using the attached inspection forms. The monthly inspection includes a visual examination of exterior surfaces
for leaks and other deficiencies of the vessel, supports, connected piping and valves and secondary containment. It also includes visual inspection and monitoring of leak detection systems
or other monitoring or warning systems (e.g., level indication/alarm or interstitial space monitoring). If an inspection reveals a leak or equipment deficiency outside of normal operating
conditions, corrective action shall be taken promptly to eliminate the leak or deficiency. Deficiencies noted during the inspection are
recorded as a Work Order. The inspector will conduct the following facility site inspection activities: I. Visually inspect exterior surfaces of storage vessels and oil-filled equipment
and associated pipes, valves and other appurtenances and identify any leaks, cracks, area of wear, external wall thinning, swelling, excessive corrosion or mechanical deficiency. 2.
Visually inspect vessel/equipment supports and containment structures for excessIve settlement, apparent structural weakness, cracks or other deficiency that would allow the secondary
containment to leak. 3. Inspect and monitor existing leak detection systems (for example, observation ports on double-bottom tanks), cathodic protection equipment and other warning systems
such as alarms and level gauges. If, during the monthly inspection, the inspector observes a spill of oil from any of the equipment, the inspector shall immediately initiate the oil
spill response procedures outlined in Section 6.0 of this spec Plan.

-Hunter Mesa Compressor Station Garfield County File Number LlPA-6627 Dear Aleta; The Department of Building and Planning received submittal of the above referenced application on October
20, 2010 for technical completeness review. Though the submittal is very comprehensive and well put together there are several items required by the Garfield County Land Use Resolution
of 2008 (ULUR), as amended, that have not been satisfied. Please respond to the following items: Please respond to the following items: 1. The application states that the request is
for a 'Compressor Station' and 'Storage'. Based upon our discussions there is no need for a particular permit to be issued for the use of storage so long as the storage on the site is
an accessory use to the Compressor Station. Please revise the application form and project description for clarity. 2. Section §4-502 C.3. lists the required components for a "site plan",
including legal description, etc. (see code for detail). That site plan is then attached to the Resolution to graphically describe the approvals granted. Though the submitted existing
conditions map are helpful, as is the Kahuna Ventures Plant Layout plot plan, we will need an official site plan that incorporates all of the improvements on the 5. 19-acre .site (it
appears that the submitted drainage plans fUnction best as the site plan, with the addition of other required items). Descriptive items such as size of the enclosures and building height
would be included on the site plan (this is included in the narrative but should also be shown on the site plan.) 3. It is not clear that Barbara J. Morris has the authority to sign
the Surface Facility Easement with Antero Resources Pipeline Corporation. The Certificate of Limited Partnership of B.J.M. Ltd. In paragraph 15 provides "[u]nder the provision of Article
of Limited Partnership ... any one or more of such general partners are authorized to execute any and all documents necessary to conveyor transfer title to any such [partnership] asset,
subject to Article IX of the Articles." Since we do not know what is in Article IX of the Articles of Limited Partnership, we do not know if there are any limitations placed on Ms. Morris's
authority to encumber real property. We either 108 Eighth Street, Suite 40/' Glenwood Springs, CO 81601 (970) 945-8212' (970) 285-7972' Fax: (970) 384-3470
need the Articles of Limited Partnership of B.J.M. Ltd., or we need a recorded Statement of Authority per C.R.S .. § 38-30-172 demonstrating Barbara J. Morris has authority to act on
behalf of B.J.M. Ltd. 4. Applicant provided an unrecorded Statement of Authority from Antero Resources Pipeline Corporation that Mark Mauz had authority to enter into the Surface Facility
Easement. (Also, although notarization is not required, it Is worth noting that the notarization is deficient.) We need a recorded Statement of Authority for Mr. Mauz. 5. The Statement
of Authority for Alvyn Shupp must be re.corded. The same issue with notarization occurs on this document. 6. The County requires a representation from an authorized representative of
Antero that it will comply with the conditions in the Surface Facility Easement. We've accepted such representations in the past as outlined below: "Companv name will comply with all
the terms and conditions associated with the company's right to [identify permitted activity, e.g. lay pipelines] as set forth in the following documents: [explicitly list all the easements,
grants and surface use agreements, preferably including the reception #]." 7. Please provide a list of the Air Quality Permits CDPHE will require of this site. Section 4.6 of the EIS
states that permits are necessary but does not include a list or description. The Code requires that an application provide the necessary information in order to be determined complete
within 60 days of the date of the 'technically incomplete' letter. I would not anticipate that this would be an issue but I did want to let you know. Please feel free to contact me with
any questions regarding the submittal requirements. Sincerely. Cc: Phil Vaughan File

REVISION-(2)-6-13-11.pdf Good morning, Kathy! I am forwarding a revised fence layout for the Hunter Mesa Compressor Station. The fence was modified to exclude the Antero slug catcher/pig
launcher and associated facilities located west of the Compressor Station site. As authorized by the LUCP, the 7-foot fence will enclose the compressor station. Valerus has applied for
a building permit for the fence. As Phil notes below, revising the emergency egress and other EAP components affected by the fence change will be coordinated with the Rifle Fire Protection
District. Valerus proposes to install the fence following site startup and cleanup, rather than prior to site startup, as previously proposed. I believe the fence layout and schedule
changes constitute a non-substantial change, based on my review of definitions for substantial and non-substantial change in the ULUR of 2008, as amended. Please let me know if there
is anything else you need from me! I look forward to hearing from you. Aleta Powers Environmental SCientist/Principal ERO Resources Corporation Consultants in Natural Resources and the
