Should Colorado keep stricter state methane rules even if federal rules are weakened?
Colorado has adopted state methane emissions rules for oil and gas operations that largely mirror Biden-era EPA regulations the Trump administration now proposes to roll back. For operators in the state's oil and gas sector, the state rules remain in force regardless of federal changes.
Why it matters
Colorado's Air Quality Control Commission finished two years of rulemaking in September aimed at cutting oil and gas methane emissions, adopting most of the Biden administration's EPA methane rules. The state's approach means compliance obligations for producers in Colorado are set at the state level even as federal requirements are proposed for rollback.
Marginal wells, defined as producing 15 barrels of oil a day or less, make up 67% of Colorado's wells and about 7% of domestic oil and gas production. The Trump administration estimates its revised federal regulations would save $45 billion, while the federal flaring proposal would require 95% methane destruction.
The players
Colorado Air Quality Control Commission
The state body that writes air pollution rules, including the methane standards that govern oil and gas emissions statewide.
Colorado Energy and Carbon Management Commission
The state regulator overseeing oil and gas well operations in Colorado, which banned routine methane venting and flaring at well sites.
U.S. Environmental Protection Agency
The federal regulator whose Region 8 office, based in Denver, oversees Colorado and five other states and sets national methane rules for the industry.
The details
Colorado's Energy and Carbon Management Commission banned venting or burning off methane at well sites except in emergencies. The Air Quality Control Commission began requiring nonpolluting controllers in 2021, with phase-out of polluting controllers, pumps and compressors scheduled by 2027 in ozone-affected areas and by 2029 elsewhere in the state. Colorado also adopted a first-in-the-nation rule tying oil and gas production to methane emissions.
Timeline
2021: Colorado began requiring nonpolluting controllers at oil and gas sites.
September 2026: Colorado finished two years of methane rulemaking.
2027: Polluting controller phase-out deadline in ozone-affected areas.
2029: Polluting controller phase-out deadline for the rest of Colorado.
Market Landscape
Colorado is adopting state-level methane standards that track the Biden-era EPA rules the Trump administration now proposes to rescind. The divergence means oil and gas operators in Colorado face state-set requirements even as federal obligations may loosen.
Oil and gas operators in Colorado should plan for state-set methane compliance, including the banned venting and burning of methane at well sites outside emergencies. Operators should budget for controller and compressor upgrades ahead of the 2027 and 2029 phase-out deadlines, and consult qualified counsel on how federal changes interact with state obligations.
The takeaway
Operators should treat Colorado's state methane requirements as binding regardless of federal rollbacks. Calendar the 2027 and 2029 controller phase-out deadlines and track the federal comment period, and review compliance plans with qualified counsel.
What happens next
The federal proposed rule is open for a 45-day public comment period, and Colorado's polluting controller phase-out deadlines fall in 2027 and 2029.
