EPA Stays Air Pollution Sanctions for Pennsylvania Power Plants
Summary
The Environmental Protection Agency (EPA) is making an interim final determination (IFD) that Pennsylvania has submitted revisions to the SIP that satisfy the requirements under the Clean Air Act (CAA) to implement RACT for these EGUs for the 1997 and 2008 ozone NAAQS. The effect of this IFD is to stay emission offset sanctions and defer the imposition of highway funding sanctions triggered by an August 2022 EPA partial disapproval of a prior Pennsylvania SIP addressing RACT for these EGUs. Proposed elsewhere in this issue of the Federal Register, EPA is proposing approval of a revision to Pennsylvania's State implementation plan (SIP), as submitted April 10, 2024, to address reasonably available control technology (RACT) nitrogen oxides (NO<INF>X</INF>) emission limits and requirements for the coal-fired electric generating units (EGUs) equipped with selective catalytic reduction (SCR) at the Keystone, Conemaugh, Homer City, and Montour facilities for the 1997 and 2008 ozone national ambient air quality standards (NAAQS).
Compliance Requirements
- #1
Submit comments identified by Docket ID No. EPA-R03-OAR-2024-0302 at www.regulations.gov, or via email to goold.megan@epa.gov; Do not submit electronically any information you consider to be confidential business information (CBI) or other information whose disclosure is restricted by statute; Multimedia submissions (audio, video, etc.) must be accompanied by a written comment; Petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by [INSERT DATE 60 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]; If issues are raised during the public comment period of the proposed plan approval which cannot be addressed and the revised plan is ultimately disapproved, the new source offset sanction shall reapply immediately and the highway sanction shall apply immediately on the date of the final disapproval if that date is more than six months after the date the offset sanctions became effective, which was March 15, 2024
Market Impacts
Two-to-one new source emissions offset sanction was in effect since March 15, 2024, creating barriers to new construction and expansion projects requiring emission offsets; Interim final determination stays offset sanctions and defers highway funding sanctions, removing immediate regulatory barriers to new projects and infrastructure development; Implementation of NOx emission limits and RACT requirements for coal-fired EGUs with SCR at Keystone, Conemaugh, Homer City, and Montour facilities as established in EPA's August 31, 2022 FIP
Validated Company Impacts
SOUTHERN CO
Southern Company operates electric utilities and power generation assets, but this specific rule targets only four named coal-fired power plants in Pennsylvania with SCR technology for NOx RACT requirements. Southern Company's operations are primarily in the Southeast and include natural gas distribution and renewable energy, with no indication of owning or operating the specific Pennsylvania facilities mentioned in the rule. The rule directly addresses environmental regulations for coal-fired power plants, which perfectly aligns with the company's 'Environmental Regulations' risk factor. The rule's focus on emission control requirements and compliance costs matches the company's identified high costs associated with regulatory compliance.
NEXTERA ENERGY INC
NextEra Energy operates primarily in clean energy and wholesale markets with no coal-fired generation assets, while this rule specifically targets coal-fired electric generating units at four named Pennsylvania facilities. The company's business model focuses on renewable energy, natural gas, and nuclear generation, with no operational overlap with the affected facilities or coal-fired power plants. The rule directly impacts multiple core risk factors in the company's profile, particularly Regulatory and Legislative Changes, Environmental Compliance Costs, and Project Development Restrictions. The stay of emission offset sanctions and deferral of highway funding sanctions directly addresses regulatory barriers that could prevent or delay power generation project development, while the RACT requirements for NOx emissions align with environmental compliance cost concerns.
PPL Corp
PPL Corp operates Pennsylvania Regulated electric utility segment, which includes ownership and operation of coal-fired power plants subject to the EPA's RACT requirements for NOx emissions. The rule specifically addresses compliance for generating facilities in Pennsylvania where PPL has significant operations, making the company directly affected by the emission limits and sanction provisions. The rule specifically targets coal-fired electric generating units with selective catalytic reduction technology at four named Pennsylvania facilities, while the company's disclosed risk factors focus on financial reporting, accounting policies, and general regulatory cost recovery without any mention of environmental compliance, air quality regulations, or power generation operations. There is minimal overlap as the company's regulatory risks appear to relate to rate recovery and political climate rather than environmental emission controls.
Talen Energy Corp
Talen Energy operates power generation facilities subject to environmental regulations and emission allowance requirements, directly aligning with this rule's focus on coal-fired electric generating units and NOx emission limits. The company's business model involves emission allowance management, which would be directly impacted by the RACT requirements and sanction provisions affecting the specific Pennsylvania facilities mentioned. The rule specifically targets coal-fired electric generating units with selective catalytic reduction at four named Pennsylvania facilities, while the company's disclosed risk factors focus on weather events, PJM capacity penalties, hedging losses, wholesale sales volatility, and operational restructuring with minimal regulatory compliance risks mentioned. There is no direct alignment between the company's identified risks and this facility-specific air quality regulation.
