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

The Emission Guidelines for Existing Other Solid Waste Incineration (OSWI) Units (40 CFR Part 60, Subpart FFFF) were proposed on December 9, 2004 (69 FR 71472), promulgated on December 16, 2005 (70 FR 74892), and amended on November 24, 2006 (71 FR 67806). Under the proposed rule, the Emission Guidelines 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 additional sub-categories: very small municipal waste combustion (VSMWC) units that combust less than 35 tons per day (TPD) 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 states plan that was developed by the air quality program administrator to implement the emission guidelines. On August 31, 2020, the EPA published a proposed rule in the Federal Register for the OSWI NSPS and EG rules that addressed the requisite CAA section 129(a)(5) periodic review (85 FR 54178), as well as other proposed changes to the standards. The EPA is finalizing its CAA section 129(a)(5) review, including our determination that there are no developments in practices, processes, or control technologies that warrant revisions to the OSWI standards and requirements. The EPA is finalizing certain other revisions, including the addition of a subcategory of new VSMWC or IWI units that have a capacity to combust less than 10 TPD of waste that are constructed on or after August 30, 2020, including changes to applicability-related and definitional changes; changes to the startup, shutdown, and malfunction (SSM) provisions; changes to testing, monitoring, recordkeeping, and reporting requirements; and other miscellaneous technical and editorial changes. The EPA is also finalizing electronic reporting requirements for submittal of certain reports and performance test results. This ICR includes the burden associated with the existing rule requirements and the incremental burden associated with the final rule. This information is being collected to assure compliance with 40 CFR Part 60, Subpart FFFF.
