40 CFR Part 60 Subpart OOOOc — Emissions Guidelines for Greenhouse Gas Emissions From Existing Crude Oil and Natural Gas Facilities

§ 60.5360c

§ 60.5360c What is the purpose of this subpart?

This subpart sets emission guidelines and compliance schedules for controlling greenhouse gas emissions from existing oil and gas facilities. The specific types of facilities covered, the standards that apply to them, and the compliance dates are listed in table 1 of this subpart. If this subpart's requirements conflict with the general requirements in subpart A or Ba, this subpart's requirements control.

§ 60.5361c(a)

§ 60.5361c(a) Scope

This subpart regulates greenhouse gas emissions, specifically methane, from existing oil and gas facilities that were built, modified, or reconstructed on or before December 6, 2022.

§ 60.5361c(b)(1)

§ 60.5361c(b)(1)

This provision clarifies that for purposes of federal Prevention of Significant Deterioration (PSD) permitting rules, greenhouse gas emissions from oil and gas facilities covered by this subpart are considered a "regulated pollutant" under the Clean Air Act. This means GHG emissions from these facilities may trigger PSD permit requirements if they meet applicable thresholds in federal rules or in EPA-approved state implementation plans that incorporate those federal definitions.

§ 60.5361c(b)(2)

§ 60.5361c(b)(2)

This provision addresses how greenhouse gas emissions from facilities covered by a state plan under this subpart are treated for federal Prevention of Significant Deterioration (PSD) permitting purposes. It says that GHG emissions from these facilities are considered "subject to regulation under the Act" (which can trigger PSD review) rather than being exempt simply because they are covered by a Clean Air Act Section 111 standard.

§ 60.5361c(b)(3)

§ 60.5361c(b)(3)

This provision clarifies that for Title V operating permit purposes (under 40 CFR Part 70), greenhouse gas emissions from facilities covered by a state plan under this subpart count as a "pollutant subject to regulation" – meaning those GHG emissions can trigger Title V permitting requirements just like any other regulated pollutant under section 111 of the Clean Air Act.
