Colorado Oil and Gas Compliance

Colorado has some of the most detailed state rules for oil and gas emissions. The air side sits with the Colorado Department of Public Health and Environment under Regulation 7, which includes the ONGAEIR annual emissions inventory and the greenhouse gas intensity program. The well side sits with the Energy and Carbon Management Commission, the agency formerly known as the COGCC.

These posts cover what Regulation 7 requires, how the intensity program and its verification factor work, what an ONGAEIR filing involves, and how to find Colorado wells and permits in the state systems.

Colorado's rules change often, and several of these posts focus on a single moving piece, such as the verification factor or the June 30 ONGAEIR deadline, and explain what it means in practice. The federal methane rules and Subpart W reporting, which apply in Colorado alongside the state program, have hubs of their own.
