Learn More🌫️Colorado Regional Haze Regulation and Business Implications
The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove a regional haze state implementation plan (SIP) submission submitted by the State of Colorado under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the program's second implementation period. Colorado's 2022 SIP submission addresses the requirement that states revise their long-term strategies every implementation period to make reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. We propose to base our partial disapproval of Colorado's long-term strategy on its inclusion of insufficiently justified enforceable source closures that are not consistent with statutory requirements. Colorado's 2022 SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. Concurrently, the EPA is proposing to approve a revision to Colorado's SIP consolidating existing regional haze provisions into the same regulation where the State's new, second planning period provisions are located.

Learn More🏠Restore Dust-Lead Hazard Standards
The Environmental Protection Agency (EPA or the Agency) is correcting a final rule that appeared in the Federal Register of November 12, 2024, that finalized several revisions to EPA's lead-based paint (LBP) regulations. Subsequent to publication, the Office of the Federal Register (OFR) informed the Agency that there were errors in the amendatory instructions that describe specific revisions for two sections of the regulation. In the Federal Register of December 16, 2024, EPA published a technical correction to the final rule that explained the errors and the corresponding technical corrections that the Agency believed would address the errors identified by the OFR. Unfortunately, that technical correction did not fix the amendatory instructions prior to the effective date of the final rule. As a result, when the final rule became effective on January 13, 2025, three subparagraphs of regulatory text were inadvertently deleted--a change to the post-abatement regulatory activities that EPA did not intend to make. This action corrects that error by restoring the inadvertently deleted text in the regulations.
