22 Schedule Page 1 of 1 Sponsor: Low Southwestern Public Service Company Combustion Residual Disposal The fly ash is collected by either electrostatic precipitator (Harrington Station Unit 1) or bag house (Harrington Station Unit 2 and 3 and Tolk Station Units 1 and 2). The ash is dry conveyed to storage silos for ultimate sale into markets including cement replacement markets. Alternatively, it can be conditioned with water and deposited into storage pits for future sale into markets such as road or parking lot base. None of the Units utilize scrubbers for emission controls. Thus no Combustion Residuals related to scrubbers are produced. The bottom ash falls to the bottom of the furnace, is cooled by water and is removed by a drag chain to a point outside of the boiler building. It is then allowed to dewater and it is picked up by a front-end loader and loaded into dump trucks by the current Southwestern Public Service Company ("SPS") contractor, Lafarge, who manages and processes all ash processed by SPS for beneficial use and resale. It is then moved to a storage area and sold as is or crushed and screened into different sizes and then resold for use as fill material for pipelines, road base, ice skid control and topping rock for asphalt paving sealing. All costs associated with the handling, processing storage and sale of the ash are paid by Lafarge. SPS then receives a percentage of the overall sales of the ash to beneficial use markets.
