WESTINGHOUSE NON-PROPRIETARY CLASS 3 to LTR-RAC-20-94 Date: December 18, 2020 Enclosure 9 Response to Request for Additional Information Table 6 - Industrial Incinerator; Emission Calculations for Metals, Acid Gases, and Dioxin/Furans

1 AP-42 Chapter 2.1, Refuse Combustion, Table 2.1-12 does not list HAP emission factors for the Industrial/Commercial Multiple Chamber Combuster source category. Therefore, the emission factors for Mass Burn/Modular Excess Air Combustors (Tables 2.1-2 and 2.1-7) are shown above. As these emission factors are for mass burning of municipal solid waste, they are believed to be conservative (i.e. they should overestimate emissions from the small incinerator operated at Westinghouse).
2 The incinerator is equipped with multi-layered inherent radiological controls for the purpose for recovering uranic materials. These controls include quenching/wet scrubbing/absorption/demisting/HEPA filtration prior to discharge to the atmosphere. Therefore, the highly controlled SD/FF (spray dryer/fabric filter) and DSI/FF (duct sorbent injection/fabric filter) emission factors have been selected from Tables 2.1-2 and 2.1-7, respectively.
3 These are preliminary emission estimates based on best available data from AP-42. The renewed permit will include a condition to test and determine actual emisions from the incinerator.
Example Calculation:
tons throughput lbs emissions lbs emissions A hour x C ton throughput = D hour tons throughput lbs emissions 1 ton B year x C ton throughput x 2000 lbs tons emissions
= E year
