The Department of Environmental Quality proposed amendments to the Permit By Rule (PBR) for the oil and natural gas sector. The amendments would allow for the use of legally and practicably enforceable (LPE) limits when determining a facility's eligibility for the PBR, clarifying source eligibility criteria for the PBR and ensuring that current PBR allows facilities potentially subject to the new source performance standards at 40 C.F.R. Part 60, Subpart OOOOb to take LPE limits to avoid applicability of the federal requirements for certain equipment. A hearing will be held April 24, 2024. Comments are due the same date.
