COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
OGLA	Form: (02A) 400133072 03/08/2011	GENERAL SITE 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 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., BMPs associated with stormwater management) sufficiently protective of the nearby surface water. The moisture content of any drill cuttings in a cuttings pit, trench, or pile shall be as low as practicable to prevent accumulation of liquids greater than de minimis amounts. At the time of closure, the drill cuttings must also meet the applicable standards of Table 910-1. No portion of any pit that will be used to hold liquids shall be constructed on fill material, unless the pit and fill slope are designed and certified by a professional engineer, subject to review and approval by the director prior to construction of the pit. The construction and lining of the pit shall be supervised by a professional engineer or their agent. The entire base of the pit must be in cut. Flowback and stimulation fluids must be sent to tanks to allow the sand to settle out before the fluids can be placed into any pipeline or pit located on the well pad. The flowback and stimulation fluid tanks 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 (per Rule 604.a.(4)).

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Construction	Form: (02A ) 400133072 4/17/2011	Chevron will ensure 110 percent secondary containment for any volume of fluids contained at the well site during the drilling and completion operations, including construction of a berm or diversion dike, collection trench, and the use of site grading to protect the nearby drainage wash.
Wildlife	Form: (02A ) 400133072 4/17/2011	Powerlines will be designed to minimize raptor electrocutions by incorporating designs to minimize risks. The cutting pit will be fenced with 32" high woven wire to protect wildlife and domestirc animals. Netting will be installed to prevent access by migratory birds.
Pre-Construction	Form: (02A ) 400133072 4/17/2011	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.
Interim Reclamation	Form: (02A ) 400133072 4/17/2011	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 distrubed area not needed for well operation will be revegetated after the site has be properly prepared - recontouring the area to blend with surrounding topography. Broadcast certified seed using seed blend recommended by BLM, in falling (Sept 2011) seeding prior to prolonged ground frost.
Drilling/Completion Operations	Form: (02A ) 400133072 4/17/2011	A closed loop system will be implemented during drilling, using a cuttings catch pit, dewatering system, centrifuge system. Any skim oul will be truck to Chevron Main Water Plant (4 miles) and pipelined to an oil gathering collection station.
General Housekeeping	Form: (02A ) 400133072 4/17/2011	Chevron trains all employees in safe work practices, good environmental stewardship, 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.
Site Specific	Form: (02A ) 400133072 4/17/2011	This well site was selected to utilize one location for 2 directionaly drilled wells, this locaiton is located along an existing lease road. These two production wells will have have two flowlines (using only one trench) to a centralized production facility offsite, no large haul trucks will be needed to collect produced fluids. There will be no holding tanks on this location.
Planning	Form: (02A ) 400133072 4/17/2011	Any waste products will be handled by RN Industries, trash will be confined in a covered container. After the rig is off the location the well site will be cleaned and all refused removed by Rangely Trash Serivce, and hauled to the approved landfill in Rio Blanco County. A portable toilet will be supplied for human wate.
Storm Water/Erosion Control	Form: (02A ) 400133072 4/17/2011	Top soil salvage and storage. Top soil will be stockpiled where no vehicle traffic will cross the mound. The stock piles will be protected from the wind and water erosion through the use of suitable weed free mulch and seeding.
