With this direct final rule, the Environmental Protection Agency (EPA) is taking action to approve the negative declarations for several designated facility classes in various states of Region 8. First, the EPA is taking direct final action in approving the negative declarations for small municipal waste combustor (MWC) units submitted by the states of Colorado, Montana, North Dakota, South Dakota, and Wyoming. Second, the EPA is taking direct final action in approving the negative declarations for large MWC units submitted by the states of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming. Third, the EPA is taking direct final action in approving the negative declarations for commercial industrial solid waste incineration (CISWI) units submitted by the states of Montana, South Dakota, Utah, and Wyoming. Fourth, the EPA is taking direct final action in approving the negative declarations for other solid waste incineration (OSWI) units submitted by the states of Montana, North Dakota, South Dakota, Utah, and Wyoming. Each state included in this action has notified the EPA in a letter of negative declaration that there are no existing designated facilities, of the source category specified in each particular letter of negative declaration, subject to the requirements of sections 111(d) and 129 of the Clean Air Act (CAA or the "Act") currently operating within the jurisdictional boundaries of their state. The EPA is accepting the negative declarations in accordance with sections 111(d) and 129(b) of the Act. This is a direct final action without prior notice and comment because the action is deemed noncontroversial.
