On September 4, 2021, the Pennsylvania Department of Environmental Protection (PADEP) published notice of its final technical guidance titled “Guidelines for Implementing Area of Review (AOR) Regulatory Requirement for Unconventional Wells,” No. 800-0810-001 (Sept. 4, 2021) (AOR Guidance). See 51 Pa. Bull. 5757 (Sept. 4, 2021). The AOR Guidance clarifies the AOR as “1,000 feet in all directions” from the plan view projections for horizontal and vertical unconventional wells. See 25 Pa. Code § 78a.52a(a). Vertical buffer distance for offset wells located within the AOR is 1,500 feet for all unconventional wells. See 25 Pa. Code § 78a.73(c). The final guidance document was effective upon date of publication, replacing PADEP’s 2016 guidance. Operators should reference the AOR Guidance regarding well placement and offset wells, for evaluating and monitoring nearby wells to prevent communication between wells, and for reporting and resolving incidents. The AOR Guidance also serves as an overview of PADEP’s well adoption permitting process.
Final issuance of the AOR Guidance followed a 60-day public comment period during which PADEP received approximately 55 comments from 10 commenters and made several changes to the draft version. Key changes to the AOR Guidance, as identified in the Pennsylvania Bulletin, include:
- clarifying the ability of operators to survey an area that extends beyond the prescriptive AOR regulatory language;
- removing language assigning responsibility for recently plugged offset wells to the operator who had completed the plugging;
- relocating language pertaining to briefing the hydraulic fracturing operations team about adjacent operator coordination;
