Approval of State Plans for Designated Facilities and Pollutants; Missouri; Hospital, Medical, and Infectious Waste Incineration (HMIWI) Units

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.
