Action Leakage Rates for Leak Detection Systems. (Supplemental BackgroundDocument for the Final Double Liners and Leak Detection Systems Rule for Hazardous Waste Landfills, Waste Piles, and Surface Impoundments)

摘要

The document supplements the original background documents supporting the 1986and 1987 proposals for double liners and leachate collection and removal systems, and liners and leak detection system rules for hazardous waste landfills, surface impoundments, and waste piles. A lot of information has been generated since the 1986 and 1987 proposals that further support this rulemaking. In particular, data on actual flow rates at double-lined landfills and surface impoundments and on top liner performance has been collected and evaluated, flow models have been applied to calculate action leakage rates, and a number of technical guidances have been published. The document discusses each of these.
