Western Maryland Power Plant Siting Study: Comparison of Solid Waste Disposal Issues at Three Candidate Sites

摘要

This document is one of a series of technical reports prepared for the Western Maryland Power Plant Siting Study. An array of solid waste disposal issues are compared for the three candidate sites (FP-12 in Frederick County, WP-14 and WP-26 in Washington County) remaining after the six to three area study phase. An 1890 MW conventional, coal-fired power plant would produce about 46 million cubic yards of solid waste over a 33 year period. The study evaluated potential impacts of a blend of fly ash and fixed scrubber sludge disposed in landfills with a design to maximize waste isolation and minimize permeate or leachate production. All three candidate sites appear to have adequate waste disposal capacity. Varied ground water flow directions and potential dilution limitations in the areas draining FP-12 and WP-14 make monitoring, detection, and potential mitigation options more complex and costly than at WP-26.
