Open for Comment: Air Plan Approval; Michigan; Determination of Attainment by the Attainment Date for the 2015 Ozone Standards

By CIV.IQ May 29, 2026
Environmental Protection Agency — The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Detroit, Michigan nonattainment area ("Detroit area" or "area") attained the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. This determination relies on the EPA's concurrence on an exceptional events request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on February 19, 2026, and concurred on by the EPA on March 24, 2026. Therefore, the EPA is proposing to take final agency action on Michigan's exceptional events request. This action, if finalized, will fulfill the EPA's statutory obligation to determine whether the Detroit area attained the 2015 ozone NAAQS by the Moderate attainment date of August 3, 2024.

Open for Comment: Regulation for Federal Financial Assistance

Management and Budget Office — The Office of Management and Budget (OMB) proposes to revise the Guidance for Federal Financial Assistance to improve government- wide policies and requirements related to the management of grants, cooperative agreements, and other forms of assistance. OMB is proposing revisions that would improve transparency, accountability, and oversight for Federal awards across the Federal Government. This includes ensuring that American tax dollars are not wasted or misused, activities performed under Federal awards are consistent with law and policy, and recipients are held accountable when they fail to meet relevant standards. The revisions also aim to ensure that basic American principles of equality and equal opportunity are upheld throughout all stages of the award making process and that unlawful discrimination is no longer permitted. Proposed changes also include providing further clarification on the regulatory status of the OMB requirements and on the process for future updates to the government- wide requirements. Finally, OMB also proposes changes to reduce recipient burden. The listed Federal grant-making agencies propose conforming changes to their respective adopting regulations, or, in the case of some agencies and other entities, establishing new adopting regulations or policies. The proposed changes reflect the administration's commitment to transparency, accountability, and proper oversight for the Federal grantmaking process. The proposed regulations seek to ensure that American tax dollars are ultimately used to serve the needs of the American public. (45 days remaining)

Open for Comment: Zero-Based Regulating

Energy Department — This proposed rule would insert sunset provisions into certain regulations, consistent with the Executive Order (E.O.), Zero-Based Regulatory Budgeting to Unleash American Energy (April 9, 2025), and agency policy. Each sunset provision would establish a conditional sunset date for covered regulations, as defined by the E.O. In this notice of proposed rulemaking (NOPR), the U.S. Department of Energy (DOE) proposes regulatory revisions identical to those set forth in a direct final rule published elsewhere in this issue of the Federal Register. If DOE receives significant adverse comments, DOE will publish a notice of withdrawal for the direct final rule and will proceed with this proposed rule. (31 days remaining)

Open for Comment: Approval of Source-Specific Air Quality Implementation Plan; New York; Big Six Towers Inc.

Environmental Protection Agency — The Environmental Protection Agency (EPA) is proposing to determine a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision, for Big Six Towers Inc. (the Big Six), located at 59-55 47th Ave. Woodside, NY 11377 (the Facility), is approvable. The EPA is proposing to find that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to oxides of nitrogen (NO<INF>X</INF>) emissions from the relevant Facility sources, which are identified as three oil-fired engines. This SSSIP revision is intended to implement NO<INF>X</INF> RACT for the relevant Facility sources in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposes to determine that this rulemaking will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA). (32 days remaining)
