Clean Air Act Full Approval of Operating Permit Program; District of Columbia

EPA is taking final action to grant full approval of the District of Columbia's (the District's) operating permit program. The District's operating permit program was submitted in response to the Clean Air Act (CAA) Amendments of 1990 that required each State to develop, and submit to EPA, a program for issuing operating permits to all major stationary sources and to certain other sources within the State's jurisdiction. The EPA granted final interim approval of the District of Columbia's operating permit program on August 7, 1995. The District amended its operating permit program to address deficiencies identified in the interim approval action and this final rule approves those amendments. The EPA proposed full approval of the District of Columbia's operating permit program in the Federal Register on October 16, 2001. This final rulemaking action summarizes the adverse comments submitted on the October 16, 2001 proposal, provides EPA's responses, and promulgates final full approval of the District of Columbia's operating permit program.
