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.
