Current through Register Vol. 47, No. 20, October 25, 2024

Section 2 CCR 404-1-212 - ISOLATION OF COAL SEAMS AND GROUNDWATER

In the conduct of Oil and Gas Operations each Owner or Operator will exercise due care in the isolation of coal seams and Groundwater.

Special precautions will be taken in drilling and abandoning Wells to guard against any loss of artesian water from the stratum in which it occurs and the contamination of Groundwater by produced water, liquid hydrocarbons, or natural gas. Before any oil or gas Well is completed, all oil, gas, and Groundwater bearing formations above and below the producing formation(s) will be isolated to prevent the intermingling of formation fluids and gases between formations.
