🌍EPA Proposes Approval of Ohio's Sulfur Dioxide Maintenance Plan
The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the second 10-year maintenance plan submitted to EPA on November 7, 2024, by the Ohio Environmental Protection Agency (Ohio EPA) for the Ohio portion of the Campbell- Clermont Counties, Kentucky-Ohio maintenance area. The Ohio portion of this area consists of Pierce Township in Clermont County, Ohio. The plan addresses the second 10-year maintenance period for the 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve Ohio EPA's submittal for the area because it provides for the continued maintenance of the 2010 SO<INF>2</INF> NAAQS through the end of the second 10-year portion of the maintenance period.

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.

NMFS, upon request from the Don Young Port of Alaska (POA), hereby promulgates regulations to govern the taking of marine mammals incidental to the Cargo Terminals Replacement (CTR) project at the existing port facility in Anchorage, Alaska over the course of 5 years. These regulations, which allow for the issuance of a Letter of Authorization (LOA) for the incidental take of marine mammals during the specified activities in the specified geographical region (see Description of the Specified Activities section) during the effective dates of the regulations, prescribe the permissible methods of taking and other means of effecting the least practicable adverse impact on marine mammal species or stocks and their habitat, as well as requirements pertaining to the monitoring and reporting of such taking.

We, NMFS, designate critical habitat for five threatened Indo- Pacific coral species, Acropora globiceps, A. retusa, A. speciosa, Fimbriaphyllia paradivisa (formerly Euphyllia paradivisa), and Isopora crateriformis, pursuant to section 4 of the Endangered Species Act (ESA). Final critical habitat includes 18 specific areas encompassing approximately 237 square kilometers (km\2\; 92 square miles, mi\2\) of marine habitat in American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, the Pacific Remote Island Areas, and Hawai[revaps]i. We have considered economic, national security, and other relevant impacts of the designations, but are not excluding any areas from the critical habitat designations due to anticipated impacts.
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.
