Proposed Amendments to Rules 69.3.1 and 69.3 (Stationary Gas Turbine Engines)

Proposed Amendments to Rules 69.3.1 and 69.3 (Stationary Gas Turbine Engines)

The proposed project consists of: (1) amendments to APCD Rule 69.3 to correct U.S. Environmental Protection Agency-identified deficiencies; and (2) amendments to APCD Rule 69.3.1 to address technological limitations of combined-cycle stationary gas turbines and emission control technologies during infrequent but unavoidable cold starts and low-load operations and to limit operation of older, higher-polluting peaking turbines on days with predicted high ambient concentrations of ozone. The amendments, if adopted, will reduce peaker plant oxides of nitrogen (NOx) emissions on forecasted high ozone days and will eliminate infeasible requirements and remove an unintended regulatory barrier for deployment of modern combined-cycle turbine technologies and eventual displacement of older, less efficient, and higher NOx emitting power plants, resulting overall in a cumulative net benefit to air quality over the long term. Short-term emission increase from infrequent cold starts at existing and planned combined-cycle facilities will pose no air quality or health impacts.
