Relates to the operating permit program from sources subject to the federal Clean Air Act and power plant emissions and performance standards

This bill amends New York's environmental conservation law to clarify rules for power plants operating under the federal Clean Air Act. It prohibits electric generating facilities from using secondary fuel sources or emergency engines except during true emergencies (as narrowly defined) or per federal rules (40 CFR 60.4211). The bill also requires department approval for alternative operating scenarios in permits and explicitly excludes preventable issues like poor maintenance from qualifying as emergencies. These changes directly affect power plants subject to federal air quality regulations, ensuring stricter controls on emissions during non-routine operations.
