Air Plan Approval; Alabama; Birmingham Limited Maintenance Plan for the 2006 24-Hour PM2.5 NAAQS
Document Number: 2023-27297
Type: Proposed Rule
Date: 2023-12-13
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to approve a State implementation plan (SIP) revision submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), via a letter dated February 2, 2021. The SIP revision includes the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) Limited Maintenance Plan (LMP) for the Birmingham, Alabama maintenance area (Birmingham Area or Area). The Birmingham 2006 24-hour PM2.5 maintenance area is comprised of Jefferson County, Shelby County, and a portion of Walker County. EPA is proposing to approve the Birmingham Area LMP because it provides for the maintenance of the 2006 24-hour PM2.5 NAAQS within the Birmingham Area through the end of the second 10-year portion of the maintenance period in 2034. The effect of this action would be to incorporate into the Alabama SIP certain commitments related to maintenance of the 2006 24-hour PM2.5 NAAQS in the Birmingham Area, making them federally enforceable. EPA is also starting the adequacy process, consistent with requirements in the transportation conformity rule, for this LMP.
Approval and Promulgation of State Plans for Designated Facilities and Pollutants; Spokane Regional Clean Air Agency; Control of Emissions From Existing Large Municipal Waste Combustors
Document Number: 2023-27295
Type: Proposed Rule
Date: 2023-12-13
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove a Clean Air Act (CAA) State Plan submitted by the Spokane Regional Clean Air Agency (SRCAA). This State Plan establishes emission limits for existing large municipal waste combustors (MWC) and provides for the implementation and enforcement of these limits. SRCAA submitted this State Plan to fulfill its requirements under the CAA in response to the EPA's promulgation of Emissions Guidelines and Compliance Times for Large MWC Constructed on or before September 20, 1994 (Emission Guidelines). The EPA is partially approving the State Plan because it meets the requirements of the Emission Guidelines for existing large MWC known to operate in Spokane County, Washington. The EPA is partially disapproving the State Plan because it omits requirements for fluidized bed combustors and air curtain incinerators, which are required elements of a State Plan.
