EPA Creates Bureaucratic Timeout System for Dirty Air
Published Date: 1/17/2025
Rule
Summary
The EPA is setting clear deadlines and rules for states whose air quality areas get bumped up to Moderate, Serious, or Severe ozone pollution levels. These states must update their plans faster and follow new steps to clean the air, but they won’t have to redo everything from their old pollution level. This rule kicks in February 18, 2025, helping states focus their efforts and budgets on meeting tougher air quality goals.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
Default SIP Submission Deadlines
If an area is reclassified to Moderate, Serious, or Severe for ozone, the state must submit required state implementation plan (SIP) revisions by the sooner of 18 months after the effective date of the reclassification or January 1 of the new classification attainment year. This timing applies to all SIP elements except the CAA section 185 fee program element and can speed when new controls or rules affecting owners/operators of VOC and NOX sources must be adopted.
Severe Area Fee Program Deadline
For areas reclassified to Severe, SIP submittals addressing the CAA section 185 fee program must be submitted by the sooner of 36 months after the effective date of reclassification to Severe or January 1 of the Severe area attainment year. This determines when states must put the section 185 fee program framework in place, which can affect owners/operators of regulated emission sources in Severe areas.
RACT Implementation Deadline
Reasonably Available Control Technology (RACT) measures triggered by reclassification must be implemented as expeditiously as practicable, but no later than the sooner of 18 months after the SIP submittal deadline or the beginning of the relevant attainment-year ozone season (as listed in appendix D to 40 CFR part 58). This affects owners/operators of sources subject to RACT requirements.
Vehicle I/M Implementation Deadline
If a reclassified area requires vehicle inspection and maintenance (I/M), states must implement I/M as expeditiously as practicable but no later than 4 years after the effective date of the reclassification, unless I/M is needed earlier for attainment or to demonstrate reasonable further progress. This can affect drivers in reclassified areas by adding inspection requirements.
Relief From Some Prior Requirements
After reclassification, the EPA codified that a state is no longer required to submit SIP revisions addressing certain, but not all, requirements tied to the area's prior (lower) classification level. This can reduce some planning or control obligations that might otherwise have applied to regulated sources and states.
