About this source
Every Environmental Protection Agency document on regulations.gov, the federal rulemaking portal: pesticide tolerance proposals, NESHAP technology reviews, Clean Air Act SIP submissions, hazardous waste rule changes, ICR survey notices, and consultation rounds for any of the above. Around 320 a month. EPA is one of the heaviest users of regulations.gov, partly because the Federal Register version of any EPA action is usually shorter than the supporting docket which lives here. Watch this if you advise on environmental compliance, run an emissions program at an industrial facility, or track Toxic Substances Control Act and Clean Water Act enforcement trends. GovPing surfaces each posting with the docket ID, document type, and comment window where applicable.
What changed
The EPA is reopening the comment period for a proposed rule originally published February 27, 2026 (91 FR 9793), which seeks to approve Michigan Air Pollution Control Rules (MAPCR) Parts 6 and 8 as revisions to the Michigan State Implementation Plan. The proposed rule addresses Moderate VOC and NOx RACT requirements for three Western Michigan nonattainment counties under the 2015 ozone NAAQS, and also approves SIP-strengthening measures limiting VOC emissions from consumer products and architectural/industrial maintenance coatings. Affected parties — manufacturers, consumer product companies, and state environmental agencies — should monitor for the revised comment deadline of May 26, 2026 and submit any outstanding comments through Regulations.gov or via email.
