From the early 1900's to 1993, the Vermont Asbestos Group (VAG) mine site located on Belvidere Mountain in Eden and Lowell, Vermont was an active asbestos mine. During the mine's operation, millions of tons of 2-3% chrysotile asbestos ore was excavated. The ore excavation process generated tons of waste rock and mine tailings. In July 2007, the Vermont Agency of Natural Resources requested EPA assistance to inspect water diversion trenches previously constructed at the site which were being impacted by precipitation and drainage pathways, and to discuss short term solutions. In Oct. 2007, EPA mobilized to the VAG mine site to begin a time critical removal action (construction of diversion trenches, berms, and sedimentation basins to keep the contaminated runoff from the tailing piles from reaching the tributaries and brooks). In June 2008, EPA re-mobilized to the site to continue efforts to keep asbestos laden runoff water from leaving the property. Actions included inspection of features completed the previous fall and reworking a number of areas to be able to accept additional flow and sediment, which was necessary due to extremely heavy precipitation and ensuing runoff. New berms and trenches were constructed around the mine's original tailings pile. These structures were designed to carry runoff beyond the pile and reconnect to Hutchins Brook, maintaining the hydrologic flow to down-gradient wetlands. EPA performed a preliminary assessment/site inspection (PA/SI) to evaluate the site for potential listing on the Superfund National Priorities List (NPL).
