If your facility satisfies the definition of a major source, you may request a federally enforceable conditional major operating permit to limit the source's potential to emit and become a conditional major source. If your facility has a current air quality "major source" operating permit, you may submit a request for a new or revised operating permit with federally enforceable conditions to constrain the operation of the source and limit the source's potential to emit to attain conditional major source status. Your facility's request for a federally enforceable conditional major operating permit is subject to the public participation procedures of S.C. Regulation 61-62.1, Section II (N).
If approved, the proposed conditional major operating permit, with pollutant emissions limitations and other federally enforceable permit conditions, will limit your facility's potential to emit to below major source thresholds, therefore deferring it from Title V major source operating permit requirements. Any stationary source that has received a synthetic minor construction permit, that is not required to obtain a Title V operating permit, shall be issued a conditional major operating permit to consolidate the source's limitations on potential to emit, and shall be considered a conditional major source. In addition to federally enforceable emission limitations, your conditional major facility will be subject to more stringent monitoring, reporting, and record keeping requirements.
