Approval and Promulgation of State Air Quality Plans for Designated Facilities and Pollutants, Maryland; Control of Emissions From Small Municipal Waste Combustor (SMWC) Units; Delegation of Authority

EPA is taking direct final action to approve the Maryland Department of the Environment's (MDE) request for delegation of authority to implement and enforce the Federal plan (68 FR 5144, January 31, 2003) for small municipal waste combustor (SMWC) units under sections 111(d) and 129 of the Clean Air Act (the "Act"). The plan establishes emissions limits, compliance schedules, monitoring, operating, and recordkeeping requirements for existing SMWC units for which construction commenced on or before August 30, 1999. The request for delegation was submitted to EPA on March 28, 2005. EPA and the MDE signed a Memorandum of Agreement (MOA) which is the mechanism for the transfer of authority from EPA to the MDE. The MOA defines policies, responsibilities, and procedures pursuant to 40 CFR 62 subpart JJJ (the "Federal plan") and 40 CFR 60 subpart BBBB (Emission Guidelines), by which the Federal plan will be administered by both the EPA and the MDE.
