New source review - Kentucky

Kentucky incorporates by reference the federal regulations for New Source Review (NSR) Permitting; however, the state adds further requirements.

A summary of the additional requirements includes the following:

• Except for volatile organic compounds (VOCs) or oxides of nitrogen (NOx) emissions, emissions from existing sources in the affected area of the proposed new major source or modification, whether or not under the same ownership, shall be reduced or offset at a ratio of at least 1:1 so that there will be reasonable further progress toward attainment of the applicable national ambient air quality standard (NAAQS). Only those transactions in which the emissions being offset are from the same criteria pollutant category shall be accepted.
• The ratio of total emissions reductions of VOCs or NOx to total increased emissions of the same air pollutant shall be at least the ratio indicated for the following ozone nonattainment area classifications:
  • For marginal nonattainment areas, at least 1.1 to 1;
  • For moderate nonattainment areas, at least 1.15 to 1;
  • For serious nonattainment areas, at least 1.2 to 1;
  • For severe nonattainment areas, at least 1.3 to 1; and
  • For extreme nonattainment areas, at least 1.5 to 1.
