COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
OGLA	Form: (02A ) 400329571 10/17/2012	SITE SPECIFIC COAs: Notify the COGCC 48 hours prior to start of pad construction, rig mobilization, spud, and start of hydraulic stimulation operations using Form 42 (the appropriate COGCC individuals will automatically be email notified, including the LGD for hydraulic stimulation operations). Operator must implement best management practices to contain any unintentional release of fluids, including any fluids conveyed via temporary surface or buried pipelines. Operator must ensure secondary containment for any volume of fluids contained at well site during drilling and completion operations (as shown on the Proposed BMPs attachment); including, but not limited to, construction of a berm or diversion dike, diversion/collection trenches within and/or outside of berms/dikes, site grading, or other comparable measures (i.e., best management practices (BMPs) associated with stormwater management) sufficiently protective of nearby surface water. Any berm constructed at the well pad location will be stabilized, inspected at regular intervals (at least every 14 days), and maintained in good condition. The moisture content of any cuttings in a cuttings pit, trench, or pile shall be as low as practicable to prevent accumulation of liquids greater than de minimis amounts. If the well is to be hydraulically stimulated, flowback and stimulation fluids must be sent to tanks, separators, or other containment/filtering equipment before the fluids can be placed into any pipeline, storage vessel, or lined pit (only if an amended Form 2A has been submitted/approved and a Form 15 Earthen Pit Permitted has been submitted/approved) located on the well pad; or into tanker trucks for offsite disposal. The flowback and stimulation fluid tanks, separators, or other containment/filtering equipment must be placed on the well pad in an area with additional downgradient perimeter berming. The area where flowback fluids will be stored/reused must be constructed to be sufficiently impervious to contain any spilled or released material. All personnel must be H2S trained and proper air monitoring for H2S must be implemented during drilling, completion, and production operations. Emergency response plan for H2S must be onsite at all times.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02A ) 400329571 10/26/2012	A closed loop system will be implemented during drilling, using a cuttings "trench", dewatering system, centrifuge system. Any skim oil will be trucked to the Chevron Main Water Plant and then pipelined to the an oil gathering collection station.
Planning	Form: (02A ) 400329571 10/26/2012	Chevron trains all employees in safework practices, good environmental stewardship, health and wellness issues and to ensure that proper personal protective equipment is available and being used correctly. Chevron has up to date Spill Protection Control and Countermeasure Plans for the Rangely field.
Construction	Form: (02A ) 400329571 10/26/2012	No potion of the cuttings trench will be used to hold liquids, the trench will be constructed entirely in the cut.
Storm Water/Erosion Control	Form: (02A ) 400329571 10/26/2012	A diversion ditch will be constructed along the east and south side of location to control runoff and erosion.
