3925 N HASTINGS WAY

The 320-acre National Presto Industries (NPI) site lies almost entirely within the city of Eau Claire and abuts the town of Hallie, Wisconsin, with combined populations of over 60,000. Areas to the south, west, and north of the site are generally residential with some industry and agriculture. Site features include Waste Lagoon No. 1, the East Disposal site, and the Melby Road Disposal site (MRDS). The NPI site was owned by the United States Government War Assets Administration from the early 1940s until 1947. Government contractors manufactured radar tubes and ordnance chemicals at the facility until 1945. NPI purchased the property from the federal government in 1947 and manufactured household appliances, outboard motors, and defense-related products. By 1954, operations were entirely defense-related, with NPI manufacturing 105mm and 8-inch artillery shells. Between 1959 and 1965, NPI engaged in little to no active production at the site. Production of 8-inch shells was restarted and operated from 1966 to 1971, and the 105mm projectiles were produced from 1966 to 1980. Waste products from the plant have contaminated soil and groundwater beneath the site. EPA proposed to place the NPI site on the National Priorities List (NPL) in October 1984 and listed the site on the NPL in June 1986. Site Responsibility The NPI site is being addressed through potentially responsible party (PRP) actions under state and federal oversight.
