Weld County oil and gas spill report for April 23
April 22, 2018
The following spills were reported to the Colorado Oil and Gas Conservation Commission in the past two weeks.
Information is based on Form 19, which operators must fill out detailing the leakage/spill events. Any spill release that may impact waters of the state must be reported as soon as practical. Any spill of five barrels or more must be reported within 24 hours, and any spill of one barrel or more, which occurs outside secondary containment, such as metal or earthen berms, must also be reported within 24 hours, according to COGCC rules. Spills and leaks typically are found during routine maintenance on existing wells, though some actual "spills" do occur among the 23,000-plus wells in the county.
