The EPA has previously issued guidance on how to assess “adjacency” for this industry, but the use of the guidance has been challenged, resulting in uncertainty for the regulated community and for permitting authorities. The EPA is proposing to clarify how properties in the oil and natural gas sector are determined to be adjacent in order to assist permitting authorities and permit applicants in making consistent source determinations for this sector. In this action, the EPA is proposing two options for determining whether two or more properties in the oil and natural gas sector are “adjacent” for purposes of defining the “stationary source” in the PSD and NNSR programs, and “major source” for the title V program (referred to collectively as “source”). The preferred option w…
