NESHAP for Coal- and Oil-fired Electric Utility Steam Generating Units (40 CFR Part 63, Subpart UUUUU) (Proposed Rule)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (40 CFR Part 63, Subpart UUUUU) were proposed on May 3, 2011, and promulgated on February 16, 2012. The rule was subsequently amended on: March 24, 2015 (80 FR 15510); April 6, 2016 (81 FR 20172); and April 6, 2017 (82 FR 16736). This proposed amendment supersedes previous temporary reporting requirements and consolidates electronic reporting through the Emissions Collection and Monitoring Plan System (ECMPS) Client Tool. These regulations apply to each individual or group of two or more new, reconstructed, or existing electric utility steam generating units (EGUs) within a contiguous area and under common control. An EGU is defined as a fossil fuel-fired combustion unit of more than 25 megawatts electric (MWe) that serves a generator that produces electricity for sale, or a fossil fuel-fired unit that cogenerates steam and electricity and supplies more than one-third of its potential electric output capacity and more than 25 MWe output to any utility power distribution system for sale. New facilities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart UUUUU. 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. Any owner/operator subject to the provisions of this part shall maintain a file containing these documents and retain the file for at least five years following the generation date of such maintenance reports and records. All reports are sent to the delegated state or local authority. If there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
