On Nov. 2, the Environmental Protection Agency (EPA) issued a Notice of Proposed Rulemaking (NPRM) proposing sweeping regulations on emissions from methane, what the Biden administration considers a "super pollutant" due to its greenhouse characteristics and its indirect impacts on human health. The rule proposes enhanced monitoring requirements for new and existing sources; significant limitations on venting, and stringent standards for emissions from not just well sites (like the Trump administration rule), but also compressor sites, tanks, pneumatic controllers, and pneumatic pumps. If finalized in its current form, the rule will upend the current state of play for methane control and enforcement in the oil patch.
