Solid Waste Disposal System Sample Clauses

Solid Waste Disposal System. The Solid Waste Disposal System is designed to collect and dispose of approximately 46% of the maximum total ash generated at Units 3 and 4. This represents a nominal 19 tons per hour of bottom ash, 6.9 tons per hour of fly ash, and 2.7 tons per hour of mill pyrites. The collection system for Units 3 and 4 comprise s three sets of fly ash hoppers (economizer, air heater, and flue gas duct hoppers), pyrite hoppers and the bottom ash xxxxxx. Ash is conveyed from these hoppers to an 18,000-gallon transfer tank using jet pulsion pump and a hydroconveyor exhauster. Two two-stage material handling pump installations with a total capacity of 3,130 gallons per minute then convey this ash and water through abrasion-resistant piping. The pipe leaves the building and runs to a settling pond approximately 2,800 feet southeast of the Plant. The water used for the raw-water makeup required to offset evaporation losses. Pump-supplied return lines from the settling pond return supernatant water to an intermediate clear water pond, which than gravity-flows back through the building walls to the suction side of the ash water pumps to complete the closed loop. The disposal pond design takes into account a permit requirement for minimum seepage by providing low-permeability soil blankets where exploration defined porous outcrops or high permeability soils. The Solid Waste Disposal System covered by the financing includes only so much of the system as is external to the Plant building and includes piping from the building to the settling pond, the pond itself, return water pumps and lines, clear water pond, and piping back to the Plant building.
