Environmental Alert

On March 1, 2024, the D.C. Circuit issued its long-awaited decision in Environmental Committee of the Florida Electric Power Coordinating Group, Inc. v. EPA, No. 15-1239 (D.C. Cir. Mar. 1, 2024), in which it vacated the majority of an Environmental Protection Agency (EPA) final agency action commonly referred to as the 2015 SSM SIP Call. The agency action required states to remove provisions in their state implementation plans (SIPs) that insulate sources from liability for excess emissions occurring during periods associated with startups, shutdowns, and malfunctions (SSM). To understand the impact of this decision, it is necessary to understand both what was at issue and what the Court did (and did not) decide.
Environmental Committee is the product of a long-simmering dispute over SSM provisions.
Under the Clean Air Act, 42 U.S.C. § 7401 et seq., states are required to adopt and submit for EPA’s approval SIPs that provide for the implementation, maintenance, and enforcement of national ambient air quality standards within their jurisdictions. 42 U.S.C. § 7410(a)(1). From the time that SIPs were first required as part of the 1970 amendments to the Clean Air Act, many states have included special provisions governing SSM events. These SSM provisions generally fall into one of four categories:
- Automatic exemption provisions excluding SSM periods from otherwise applicable emissions rules;
- Director’s discretion provisions allowing state officials to independently and conclusively determine that excess emissions during SSM periods are not violations of applicable emissions rules;
- Enforcement discretion provisions allowing state officials to bar enforcement action for excess emissions during SSM periods;
