Coal Bed Natural Gas

The GPC Program issues permits and tracks compliance monitoring data for Coal Bed Natural Gas (CBM) impoundments to ensure groundwater quality.

About CBM Impoundments

The CBM industry uses unlined surface impoundments as one option for managing produced water. As the stored water soaks into the soil, contaminants in the water or already present in the soil can leach out and reach the groundwater below the impoundments. 

The GPC Program issues permits and tracks compliance monitoring data for impoundments that overlay Class III (livestock) quality shallow groundwater. Additionally, the GPC Program provides compliance monitoring data, and data obtained while drilling more than 2,000 groundwater investigation boreholes, to the general public.
