11/02/2010 | Location is in a sensitive area because of its proximity to surface water; therefore, operator must ensure 110 percent secondary containment for any volume of fluids contained at well site during drilling and completion operations.

11/02/2010 | Operator must implement best management practices to contain any unintentional release of fluids, including any fluids conveyed via pipeline.

11/02/2010 | Location is in a sensitive area because of shallow groundwater; therefore either a lined drilling pit or a closed loop system (which Williams has already indicated on the Form 2A) must be implemented.

11/02/2010 | 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., best management practices (BMPs) associated with stormwater management) sufficiently protective of nearby surface water. Any berm constructed at the well pad and frac pad locations will be stabilized, inspected at regular intervals (at least every 14 days), and maintained in good condition.

11/02/2010 | 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.

11/02/2010 | The area of the well pad 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)).

11/02/2010 | Operator will conduct regular inspections of equipment for leaks and equipment problems with appropriate documentation retained in the operator’s office. All equipment deficiencies shall be corrected. Monitoring should end approximately 30 days after well completion and/or after production has been stabilized; however, timely inspections should continue during the production phase.

11/02/2010 | The location is in an area of high runoff/run-on potential; therefore, the well pad shall be constructed as quickly as possible and appropriate BMPs need to be in place both during, after well pad construction completion, as well as during all completion operations. Standard stormwater BMPs must be implemented at this location to insure compliance with CDPHE and COGCC requirements and to prevent any stormwater run-on and /or stormwater runoff. |
