Environmental Protection Agency April 14, 2023 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Missouri on March 7, 2019. Missouri requests that the EPA approve revisions to a state regulation for the Restriction of Particulate Matter to the Ambient Air Beyond the Premises of Origin. These revisions include adding definitions that are specific to the rule, restructures the rule into the standard rule organization format, and removes unnecessary words. The revisions are administrative in nature and do not impact the stringency of the SIP or air quality. The EPA's proposed approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).

Pursuant to the Federal Advisory Committee Act, the Environmental Protection Agency (EPA) announces an upcoming meeting of the Mobile Sources Technical Review Subcommittee (MSTRS), which is a subcommittee under the Clean Air Act Advisory Committee (CAAAC). This is a hybrid (both in-person and virtual) meeting and open to the public. The meeting will include discussion of current topics and presentations about activities being conducted by EPA's Office of Transportation and Air Quality. MSTRS listserv subscribers will receive notification when the agenda is available on the Subcommittee website. To subscribe to the MSTRS listserv, send an email to MSTRS@epa.gov.
