The U.S. Environmental Protection Agency’s highly anticipated November 2021 Clean Air Act (CAA) proposal regulating methane and volatile organic compound (VOC) emissions from the oil and gas sector drew a reported 400,000 individual submissions. Through the methane proposal (Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review, 86 Fed. Reg. 63,110 (Nov. 15, 2021)), EPA seeks to expand the current VOC and methane emissions regulations that apply to new, modified, and reconstructed sources within the crude oil and natural gas production sector that were promulgated by EPA in 2012 (40 C.F.R. Part 60, Subpart OOOO) and 2016 (40 C.F.R. Part 60, Subpart OOOOa). In addition, the methane proposal includes the first nationwide methane emissions guidelines for existing sources within the oil and gas sector.
It is no surprise that EPA received a significant number of comments on the methane proposal, especially considering the relatively brief and tumultuous history of the agency’s regulation of methane emissions from the oil and gas sector under the CAA. The commenters’ views on the proposal differ considerably. Many commenters, primarily those representing the oil and gas industry and certain states, raised serious legal concerns and also questioned the technical aspects and propriety of several key components of issues with the proposal. On the other hand, commenters from other states, local governments and environmental groups urged EPA to impose even more stringent requirements, beyond those included in the methane proposal. Several key themes and legal issues emerged from these comments. This article highlights some of the potentially pivotal legal issues raised by commenters, including those related to EPA’s proposed community- based monitoring program. …
