Letter Health Consultation: Northern Land and Lumber/American Timber Homes, Gladstone, Delta County, Michigan, August 30, 2010.

摘要

Northern Land & Lumber/American Timber Homes (the site) is located at 7000 P Road in Gladstone (Delta County), Michigan along the shore of the Little Bay De Noc of Lake Michigan. Parcels of the site are located on both sides of P Road and total approximately 35 acres. In the early 1900s, Michigan Tanning & Extract Company carried out vegetable tanning activities in several buildings and outdoor locations on the site. Over the years, the site was occupied by Universal Cinder Products Company, Delta County Road Commission, Wells Crate and Lumber Company, Early American Fence Company, and possibly the Birdseye Veneer Company. Most recently (1956-1981) the site was the home of Northern Land & Lumber, a wood preserving facility. Wood preservatives used at the site may have included pentachlorophenol (PCP), creosote derivatives, and inorganic arsenical or chromate salts. Multiple transformers, possibly containing polychlorinated biphenyls (PCBs), and aboveground storage tanks were present at the site. The aboveground storage tanks were reported to contain hydraulic oil, fuel oil, and liquefied petroleum gas.
