Information

Applies only to wells designed and installed for the extraction of coalbed methane (CBM).

CBM development must follow the standards for drilling, completing, testing, and production of CBM wells as adopted by the Board of Oil and Gas Conservation.

CBM operators must offer water mitigation agreements to owners of water wells or natural springs within one-half mile of a CBM operation or within the area that the operator reasonably believes may be impacted by the CBM operation, whichever is greater. This area will automatically be extended one-half mile beyond any well adversely affected.

DNRC will designate a Technical Advisory Committee to oversee groundwater characteristics and monitoring and reporting requirements.
