NSPS for Other Solid Waste Incineration (OSWI) Units (40 CFR Part 60, Subpart EEEE) (Final Rule)

The New Source Performance Standards (NSPS) for Other Solid Waste Incineration (OSWI) Units (40 CFR part 60, subpart EEEE) apply to very small municipal waste combustion units and institutional waste incineration units. A new incineration unit subject to this subpart should meet either one of two criteria: (1) Commenced construction after December 9, 2004; or (2) commenced reconstruction or modification either on or after June 16, 2006. A very small municipal waste combustion unit is any municipal waste combustion unit that has the capacity to combust less than 35 tons per day of municipal solid waste or refuse-derived fuel. An institutional waste incineration unit is any combustion unit that combusts institutional waste and is a distinct operating unit of the institutional facility that generated the waste. Institutional waste is solid waste that is combusted at any institutional facility using controlled flame combustion in an enclosed, distinct operating unit with one of the following characteristics: (1) whose design does not provide for energy recovery; or (2) operated without energy recovery; or (3) operated with only waste heat recovery. Institutional waste also means solid waste combusted on-site in an air curtain incinerator that is a distinct operating unit of any institutional facility. In general, all NSPS 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 60, subpart EEEE.
