NPL Site Narrative for St. Regis Paper Co.

Cass Lake, Minnesota

Federal Register Notice:  September 21, 1984

Conditions at listing (September 1983): The Wheeler Division of St. Regis Paper Co. has operated a 125-acre wood-treatment facility in the rural community of Cass Lake, Cass County, Minnesota, since 1957. The site is in the Chippewa National Forest and between Pike Bay and Cass Lake. The company once used creosote in its operations but now uses pentachlorophenol and a chrome-copper-arsenic solution. The waste waters and sludges generated were buried in pits or a landfill or discharged to surface impoundments. Contamination has migrated from these disposal areas into the surrounding ground water and surface water, according to tests conducted by St. Regis. Monitoring wells on the site are contaminated, but Cass Lake municipal wells are not as yet. A private well has a low level of contamination.

St. Regis has presented a proposal to the State that includes sampling of residential wells, construction and sampling of additional monitoring wells, further investigation of soil conditions, and investigations into the feasibility of remedial measures.

Status (June 1984): St. Regis is investigating site conditions and submits quarterly monitoring reports.

The State is negotiating with responsible parties to conduct a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action.
