The Environmental Protection Agency (EPA) is approving revisions to the Missouri state plan for designated facilities and pollutants developed under sections 111(d) and 129 of the Clean Air Act (CAA) that were requested by Missouri Department of Natural Resources (MDNR) in two separate submissions made on August 8, 2011 and on July 3, 2014. This final action will amend the state regulations referenced in the state’s 111(d) plan applicable to existing Hospital, Medical, Infectious Waste Incinerators (HMIWI) operating in the state of Missouri. The state rule revisions we are approving with this action update HMIWI regulatory requirements for emission limits for waste management plans, training, compliance and performance testing, monitoring, and reporting and recordkeeping to be consistent with updates to Federal rules. These regulatory revisions we are approving into Missouri’s state plan do not impact air quality. EPA’s approval of this revision is being performed in accordance with the requirements of CAA section 111(d) as further described in the Technical Support Document that is included in this docket.
The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submittal from the Alaska Department of Environmental Conservation (Alaska DEC) demonstrating that the SIP meets certain interstate transport requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated in 2010 for nitrogen dioxide (NO<INF>2</INF>) and sulfur dioxide (SO<INF>2</INF>). The EPA proposes to determine that Alaska’s SIP contains adequate provisions to ensure that air emissions in Alaska do not significantly contribute to nonattainment or interfere with the maintenance of the 2010 NO<INF>2</INF> and SO<INF>2</INF> NAAQS in any other state.
