Abstract |
The MacGillis & Gibbs/Bell Lumber & Pole site consists of two active, adjacent wood preserving facilities, referred to as the M&G and Bell facilities, in New Brighton, Ramsey County, Minnesota. Land use in the area is residential and commercial. Several lakes, streams, and wetlands are located within 2 miles of the site. The Record of Decision (ROD) addresses the 24-acre M&G facility on the eastern portion of the site. Site features include a disposal area in the west-central portion of the facility used to dispose of PCP-contaminated wood chips, settled solids, spent treatment solutions, and copper chromium arsenic (CCA) contaminated drum shells; onsite drums; and a storage area. Investigations conducted by EPA have detected contamination of the onsite surface and subsurface soil and ground water, which is thought to be a result of leaking pipes, drippings from treated poles, contamination from the disposal area, and an onsite spill. EPA had dividied the site into two operable units (OUs) for remediation. The ROD provides an interim remedy for OU2. The primary contaminants of concern affecting the soil, debris, sludge, and ground water are organics including dioxins, PAHs, and PCP and metals including arsenic and chromium. The selected remedial action for the site is included. |
