Rule
Summary
The EPA just gave a thumbs-up to the District of Columbia saying they don’t have any big pollution sources like waste burners, oil and gas plants, or power plants that need special air quality rules. This means no new pollution controls or costs for these facilities in D.C. The rule kicks in on June 29, 2026, keeping things simple and clean for the city.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Discovered Facilities Subject to Federal Plan
The EPA notes that if any designated facilities subject to the 111(d)/129 rules are later discovered in the District, those discovered sources would be subject to the applicable Federal plan until the State submits an approvable State plan. This approval is effective June 29, 2026.
No Large Pollution Sources Identified
The EPA approved the District of Columbia's negative declarations saying there are no large municipal waste combustors, crude oil and natural gas facilities, or electric utility generating units subject to the listed Clean Air Act rules in the District. Because of that approval, no new pollution-control requirements or costs under those 111(d)/129 emission guidelines are being imposed in the District of Columbia as of June 29, 2026.
No Significant Small-Business Impact
The EPA certified under the Regulatory Flexibility Act that this approval of the District's negative declarations will not have a significant economic impact on a substantial number of small entities. That certification accompanies the final rule effective June 29, 2026.
No New Reporting or Paperwork Required
The EPA states this approval does not impose any new reporting or recordkeeping requirements and that the Paperwork Reduction Act does not apply. The final rule is effective June 29, 2026.
