NESHAP for Stationary Combustion Turbines (40 CFR part 63, subpart YYYY) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Combustion Turbines were proposed on January 14, 2003; promulgated on March 5, 2004; and amended last on April 20, 2006. The regulations apply to sources that either commenced construction or reconstruction after January 14, 2003. On August 18, 2004, these standards were amended to stay the effectiveness for the two gas-fired stationary combustion turbine subcategories (i.e., lean pre-mix gas-fired turbines and diffusion flame gas-fired turbines). Under this stay, new sources in either subcategory that are either constructed or reconstructed after January 14, 2003 are required to submit initial notification reports, but are also relieved of the obligation to comply with other reporting or monitoring requirements until EPA makes a final decision. Amendments to the NESHAP were proposed on April 12, 2019, as a result of a residual risk and technology review (RTR) required under the Clean Air Act (CAA; however, these amendments have not been finalized and no burden associated with the proposed amendments is included in this ICR. This information is being collected to assure compliance with 40 CFR Part 63, Subpart YYYY. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
