EPA Gives States Three More Years for Regional Haze Plans
Published Date: 1/6/2026
Rule
Summary
The EPA is giving states more time to submit their plans to improve air quality and protect clear skies in special natural areas. Instead of the original July 31, 2028 deadline, states now have until July 31, 2031 to get their plans in. This extra time helps states better prepare without changing any funding or costs.

States get three more years to file SIPs
The EPA moved the due date for States' third-period regional haze State Implementation Plans (SIPs) from July 31, 2028, to July 31, 2031. This change is a one-time schedule adjustment; the third planning period itself still runs through 2038.
No new costs for small businesses
The EPA states this extension does not change funding or costs and certifies under the Regulatory Flexibility Act that the rule will not have a significant economic impact on a substantial number of small entities. The rule imposes no new requirements on small entities.
Progress report and planning period dates unchanged
The EPA kept the third planning period end year at 2038 and did not change the third-period progress report due date of July 31, 2033. The SIP due date change is limited to moving the comprehensive SIP submission from July 31, 2028, to July 31, 2031.
