Air Plan Approval; AK, Fairbanks North Star Borough; 2006 24-Hour PM 2.5 Serious Area and 189(d) Plan
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Proposed rule; reopening of comment period.
SUMMARY:
The Environmental Protection Agency (EPA) is reopening the public comment period on the proposed rule entitled "Air Plan Approval; AK, Fairbanks North Star Borough; 2006 24-hour PM 2.5 Serious Area and 189(d) Plan" published on January 8, 2025. Commenters requested more time to review the proposal and prepare comments. In response, the EPA is providing an additional 30 days for the public to provide comment on all aspects of the proposed rule. The January 8, 2025, notice of proposed rulemaking also started the EPA's adequacy process for the motor vehicle emissions budgets and began the public comment period for that process. The EPA is not reopening the public comment period for the adequacy process, and it intends to proceed with the adequacy process outside of this rulemaking.
DATES:
The comment period for the proposed rule published on January 8, 2025, at 90 FR 1600, is reopened to allow more time to review the proposal and prepare comments. The EPA is reopening the comment period and the comments must be received on or before April 23, 2025.

SUPPLEMENTARY INFORMATION:
On January 8, 2025, the EPA published a notice of proposed rulemaking to approve changes to the Alaska State Implementation Plan (90 FR 1600). The changes, submitted by the State of Alaska on December 4, 2024, address Clean Air Act requirements for the 2006 24-hour fine particulate matter (PM 2.5 ) national ambient air quality standards in the Fairbanks North Star Borough Serious PM 2.5 nonattainment area. Alaska's submission includes State Implementation Plan (SIP) revisions to meet nonattainment planning requirements for emissions inventories, modeling and sulfur dioxide precursor demonstration for major stationary sources, control measures, attainment projections and progress to attainment and associated motor vehicle emissions budgets, and contingency measures. The public comment period closed on February 7, 2025. Commenters requested more time to review the proposal and prepare comments with respect to the energy efficiency and weatherization measures discussed in the January 8, 2025, notice of proposed rulemaking. 1 In response to this request, the EPA is reopening the public comment period on the proposed rule and providing an additional 30 days for the public to provide comments on all aspects of the proposed rule.
Footnotes:
1 ?90 FR 1600, January 8, 2025, section II.C.3.a.iv.
The January 8, 2025, notice of proposed rulemaking also started the transportation conformity adequacy process for the motor vehicle emissions budgets in Alaska's submitted SIP. As noted in the proposal, the EPA may find budgets adequate before the SIP submission is approved in a final rule, once the public has been provided with a comment period of at least 30 days. The EPA is not reopening the public comment period for the adequacy process, and it intends to proceed with the adequacy process outside of this rulemaking, as described in 40 CFR 93.118(f).
