1.1 Purpose and Scope. This report summarizes the activities, compliance status, annual inspection, and environmental monitoring results from calendar year 2015 for the Weldon Spring, Missouri, Site. The U.S. Department of Energy (DOE) prepares this annual report as part of the site’s long-term surveillance and maintenance (LTS&M) activities, in accordance with the requirements of the Long-Term Surveillance and Maintenance Plan for the Weldon Spring, Missouri, Site (LTS&M Plan) (DOE 2008a) and the Federal Facility Agreement for the Weldon Spring Site (DOE 2006). The Weldon Spring site is a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) site. 1.2 Site Description. The Weldon Spring site is located in St. Charles County, Missouri, about 30 miles west of St. Louis, Missouri (Figure 1). The site comprises two geographically distinct, DOE-owned properties: the former Weldon Spring Chemical Plant and Raffinate Pit sites (Chemical Plant) and the former Weldon Spring Quarry (Quarry). The former Chemical Plant is located about 2 miles southwest of the junction of Missouri State Route 94 and Interstate 64. The Quarry is about 4 miles southwest of the former Chemical Plant. Both sites are accessible from Missouri State Route 94. During the early 1940s, the Department of the Army acquired 17,232 acres of private land in St. Charles County for the construction of the Weldon Spring Ordnance Works facility. The former Ordnance Works site has since been divided into several contiguous areas under different ownership, as depicted in Figure 2. Current land use of the former Ordnance Works site includes the former Chemical Plant and Quarry, the U.S. Army Reserve Weldon Spring Training Area, the Missouri Department of Conservation (MDC), the Missouri Department of Natural Resources (MDNR) Division of State Parks (MDNR-Parks), Francis Howell High School, a St. Charles County highway maintenance (formerly Missouri Department of Transportation [MoDOT]) facility, the Public Water Supply District No. 2 water supply facility, the St. Charles County law enforcement training center, the village of Weldon Spring Heights, and a University of Missouri research park. The former Chemical Plant and Quarry areas total 228.16 acres. The Former Chemical Plant property occupies 219.50 acres, and the Quarry occupies 8.66 acres.
