The Environmental Protection Agency (EPA) is proposing to approve a portion of State Implementation Plan (SIP) revisions for South Carolina submitted by the South Carolina Department of Health and Environmental Control (SC DHEC) through letters dated August 8, 2014, and August 12, 2015, and a portion of a SIP revision for Tennessee submitted by the Tennessee Department of Environment and Conservation (TDEC) through a letter dated February 17, 2014. The South Carolina SIP revisions modify a provision that requires fossil fuel-fired steam generators having a heat input capacity of more than 250 million British thermal units (Btu) per hour (Btu/hr) to submit continuous opacity monitoring reports required by the SIP on a quarterly basis. This provision is being modified to allow such reporting on a semiannual basis instead. The South Carolina SIP does not contain any other continuous opacity monitoring report requirements for the subject sources, and this rule revision has no impact on any federal reporting requirements. Specifically, the South Carolina SIP revisions do not override any other reporting requirements that might continue to require more frequent reporting. The Tennessee SIP revision would add a new provision that requires any source subject to the State's title V operating permit program to submit emission monitoring reports required by the SIP on a semiannual basis rather than on a quarterly basis. Much like the South Carolina SIP revisions, the Tennessee SIP revision has no impact on any federal reporting requirements and does not override any other reporting requirements that might continue to require more frequent reporting. EPA is proposing to approve these changes to the South Carolina and Tennessee SIPs because they are consistent with recent proposed changes to federal regulations and because EPA has preliminarily determined that the South Carolina and Tennessee SIP revisions are consistent with the Clean Air Act (CAA or Act).
