  • EPA recently initiated a detailed study to determine if the CBM industry should be designated as a subcategory of the Oil and Gas Extraction category for purposes of establishing separate, distinct ELGs for discharges of produced water exclusively associated with the extraction of CBM. To compile information for this study, EPA is examining the nature of CBM extraction and production operations, the magnitude and characteristics of associated discharges of produced water and associated environmental impacts, current and potential produced water management, treatment, disposal and beneficial re-use technologies within the CBM industry, geographic distinctions among CBM operations; economic and financial considerations related to available re-use and technology options; and other factors.
