The Emission Guidelines for Large Municipal Waste Combustors Constructed on or before September 20, 1994 (40 CFR Part 60, Subpart Cb) were proposed on September 20, 1994; promulgated on December 19, 1995; and amended on both August 25, 1997, and May 10, 2006. The Agency received petitions on various aspects of the standards, however, and the 2006 rule was remanded in 2008. EPA is finalizing a rulemaking to address that remand, which includes a reevaluation of maximum achievable control technology (MACT) floors and the next iteration of the 5-year review of the standards as required by the CAA. The EPA is proposing revised requirements to existing subpart Cb (Emissions Guidelines and Compliance Times for Large Municipal Waste Combustors That are Constructed on or Before September 20, 1994) on January 23, 2024. The EPA is proposing the revised requirements in new subpart 40 CFR Part 60, Subpart WWWW (Emission Guidelines and Compliance Times for Large Municipal Waste Combustors Constructed on or Before January 23, 2024). Subpart WWWW applies to existing facilities constructed either on or before January 23, 2024 that own and operate municipal waste combustion (MWC) units with a combustion capacity greater than 250 tons per day of municipal solid waste (large MWC units). In general, all EG 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 the EG. The final amendments reflect the results from the MACT floor reevaluation and the 5-year review; remove startup, shutdown and malfunction exclusions and exceptions; streamline regulatory language; revise recordkeeping and electronic reporting requirements; and clarify requirements for certain air curtain incinerators. Additionally, the amendments re-establish new source and existing source applicability dates. Large MWC units that are currently subject to the New Source Performance Standards (NSPS) of subparts Ea and Eb will become “existing” sources under the amended standards and would be required to meet the revised emission guidelines (EG) under subpart WWWW by the applicable compliance date for the revised guidelines. Burdens associated with the 2006 standards are addressed separately under EPA ICR Number 1847.09 and are not included in this ICR. This ICR applies only to the incremental burden incurred by existing units due to the revisions to these standards. The guidelines do not apply directly to large MWC unit owners and operators, since they are implemented through state plans (SPs). If a state does not develop, adopt, and submit an approved state plan, or if a state’s plan is not approved, the EPA must promulgate a Federal plan to implement the emission guidelines in a state without its own SP. This information is being collected to ensure compliance with the final amendments to 40 CFR Part 60, Subpart Cb.
Increase in burden is result of requirements associated with proposed rulemaking action.
