Emission Guidelines for Existing Other Solid Waste Incineration (OSWI) Units (40 CFR part 60, subpart FFFF) (Renewal)

The Emission Guidelines for Existing Other Solid Waste Incineration (OSWI) Units (40 CFR Part 60, Subpart FFFF) apply to any air quality program in either a state or a United States protectorate with one or more existing OSWI units or air curtain incinerators that commenced construction either on or before December 9, 2004. The affected OSWI units include two sub-categories: very small municipal waste combustion (VSMWC) units that combust less than 35 tons per day of waste and institutional waste incineration (IWI) units. This Subpart does not directly affect incineration unit owners and operators; however, they must comply with the state’s plan that was developed by the air quality program administrator to implement the emission guidelines. In general, all emission guidelines 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 FFFF.
