Superfund Record of Decision (EPA Region 1): Saco Tannery Waste Pits, ME. (First Remedial Action), September 1989

摘要

The Saco Tannery Pits site is in Saco, Maine, approximately 15 miles southwest of Portland, Maine. The 233-acre site is in a rural area which includes forests and wetlands, and lies within the 100-year floodplain of Stuart Brook. Between 1959 and the early 1980s a leather tannery operator used the site to dispose of process wastes in two 2-acre lagoons and 53 smaller disposal pits. EPA and State investigations in the early 1980s led to a removal response action which included pumping liquids from three waste pits and neutralizing the remaining sludge from the pits. This Record of Decision addresses both source control and ground water remediation. The selected remedial action is contingent upon the State enacting legislation within two years designating the site as a permanent conservation area. The remedy includes pumping and offsite treatment and discharge of water from waste pits and lagoons followed by covering and revegetating waste pits.
