The purpose of this Advance Notice of Proposed Rulemaking (ANPR) is to solicit broad feedback on the most effective and efficient means of implementing the Environmental Protection Agency's (EPA) Indian Country Minor New Source Review program for sources in the oil and natural gas production segment of the oil and natural gas sector. In particular, this ANPR discusses potential new source permitting approaches to address emissions from proposed new and modified oil and natural gas production activities. One approach is a general permit, which could serve as a streamlined permitting approach for addressing emissions from new and modified minor sources and minor modifications at major sources under the Indian Country Minor NSR rule. Another approach is a Federal Implementation Plan, which could address emissions from new and modified minor sources and minor modifications at major sources. Other possible approaches include a permit by rule, which is another streamlined permitting approach. The EPA is requesting comments on all available new source permitting approaches and will take this feedback into consideration in developing a notice of proposed rulemaking for this sector under the Indian Country Minor NSR program.
