Superfund Explanation of Significant Difference for the Record of Decision (EPARegion 10): Northwest Transformer/Mission Pole Superfund Site, Whatcom County, Everson, WA., December 22, 1993

摘要

The remedial action at the Northwest Transformer Mission/Pole site in WhatcomCounty, Washington, is nearly complete. The purpose of this document is to inform the public that the final two piles of excavated soil containing 53 and 70 parts per million Polychlorinated Biphenyls (PCBs), respectively, will be disposed of at a hazardous waste landfill rather than by incineration. This document also discusses the results of the Environmental Protection Agency (EPA) reassessment of the selected remedy for groundwater (which was and remains no further action) in light of sampling results and the apparent removal of the source of groundwater contamination during remediation.
