COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
OGLA	Form: (02A ) 400310466 8/17/2012	SITE SPECIFIC COAs: Operator must implement best management practices to contain any unintentional release of fluids, including any fluids conveyed via pipeline. Operator must ensure 110 percent secondary containment for any volume of fluids (excluding freshwater) contained at well site during drilling and completion operations; 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. 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 or storage vessel 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. Any tanks and/or aboveground vessels containing fluids, if placed on the site after well completion, must have secondary containment structures. All secondary containment structures/areas must be lined. Operator must ensure secondary containment for the largest structure containing fluids within each bermed area of the injection well pad/facility during operations. The construction and lining of the secondary containment structures/areas shall be supervised by a professional engineer or their agent. Berms or other containment devices shall be constructed to be sufficiently impervious (preferably corrugated steel with a liner) to contain any spilled or released material around crude oil, condensate, and produced water storage tanks.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Drilling/Completion Operations	Form: (02A ) 400310466 8/30/2012	A closed loop system will be implemented during drilling, using a cuttings catch pit, dewatering system, centrifuge system. Any skim oil will be trucked to the Chevron Main Water Plant and pipelined to an oil gathering collection system.
Construction	Form: (02A ) 400310466 8/30/2012	The cuttings pit will be constructed to the BLM Gold Book standards. No portion of the drilling pit will be constructed on any fill material, the entire base of the pit will be in the cut. Chevron will ensure 110 percent of secondary containment for any volume of fluids contained at the well site during the drilling and completion operations, including construction of berms or diversion dikes.
Site Specific	Form: (02A ) 400310466 8/30/2012	This well site was selected to utlize existing lease roads, the lease roads are maintained by Chevron.
General Housekeeping	Form: (02A ) 400310466 8/30/2012	Any waste products will be handled by RN Industries, trash will be confined in a covered container. After the rig moves off location the well sitre will be cleaned and all refused will be removed by Rangely Trash Service and hauled to the approved landfill in Rio Blanco County. A portable toilet will be supplied for human waste.
Interim Reclamation	Form: (02A ) 400310466 8/30/2012	Any moisture content of the drill cuttings pit will be de-watered and at the time of closure the drill cuttings will meet the standards in table 910-1. The disturbed area not needed for well operations will be revegetated after the site has bee properly prepared - recontouring the area to blend with the surrounding topography.
Planning	Form: (02A ) 400310466 8/30/2012	Chevron trains all employees in safe work practices, good environmental stewartship. health and wellness issues and to ensure that proper personal protective equipment is available and is being used. Chevron has a up to date Spill Protection Control and Countermeasure Plan for the Rangely Field. Chevron has a zero tolerance policy regarding drug usage, with education and compliance programs to help reinforce these policies.
