NESHAP for Engine Test Cells/Stands (40 CFR part 63, subpart PPPPP) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Engine Test Cells/Stands (40 CFR Part 63, Subpart PPPPP) apply to either new or reconstructed engine test cells/stands located at major source facilities that are being used for testing internal combustion engines. An engine test cell/stand is any apparatus used for testing uninstalled stationary or uninstalled mobile (motive) engines. A plant site that is a major source of hazardous air pollutant (HAP) emissions emits or has the potential to emit any single HAP at a rate of 10 tons (9.07 megagrams) or more per year or any combination of HAPs at a rate of 25 tons (22.68 megagrams) or more per year. New facilities include those that commenced construction or reconstruction after the date of proposal. 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 with 40 CFR Part 63, Subpart PPPPP.
