Book Description
This proposed plan addresses the management of contamination present in various components of the quarry residuals operable unit (QROU) of the Weldon Spring site, which is located in St. Charles County, Missouri. The QROU consists of (1) residual waste at the quarry proper; (2) the Femme Osage Slough, Little Femme Osage Creek, and Femme Osage Creek; and (3) quarry groundwater located primarily north of the slough. Potential impacts to the St. Charles County well field downgradient of the quarry area are also being addressed as part of the evaluations for this operable unit. Remedial activities for the QROU will be conducted by the US Department of Energy (DOE) in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended. As part of the remedial investigation/feasibility study (RI/FS) process required for the QROU under CERCLA, three major evaluation documents have been prepared to support cleanup decisions for this operable unit.

Book Description
The U.S. Department of Energy (DOE) is conducting cleanup activities at the Weldon Spring site, which is located in St. Charles County, Missouri, about 48 km (30 mi) west of St. Louis (Figure 1.1). Cleanup of the Weldon Spring site consists of several integrated components. The quarry residuals operable unit (QROU) is one of four operable units being evaluated. In accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, a remedial investigation/feasibility study (RI/FS) is being conducted to evaluate conditions and potential responses for the following areas and/or media that constitute the QROU: (1) the residual material (soil and sediment) remaining at the Weldon Spring quarry after removal of the bulk waste (about 11 million L [3 million gal] of uranium-contaminated ponded water was also addressed previous to bulk waste removal); (2) other media located in the surrounding vicinity of the quarry, including adjacent soil, surface water, and sediment in Femme Osage Slough and several creeks; and (3) quarry groundwater located primarily north of Femme Osage Slough. Potential impacts to the St. Charles County well field downgradient of the quarry area are also being addressed as part of QROU RI/FS evaluations. For remedial action sites, it is DOE policy to integrate values associated with the National Environmental Policy Act (NEPA) into the CERCLA decision-making process. The analyses contained herein address NEPA values as appropriate to the actions being considered for the QROU. A work plan summarizing initial site conditions and providing conceptual site hydrogeological and exposure models was published in January 1994. The RI and baseline risk assessment (BRA) reports have been completed. The RI discusses in detail the nature and extent and the fate and transport of contamination at the quarry area.

Book Description
The US Department of Energy (DOE) is conducting cleanup activities at the Weldon Spring site, which is located in St. Charles County, Missouri, about 48 km (30 mi) west of St. Louis. The Weldon Spring site consists of two noncontiguous areas -- the chemical plant area, which includes four raffinate pits, and the quarry. Cleanup activities at the Weldon Spring site are conducted in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended, incorporating the values of the National Environmental Policy Act (NEPA). The contents of the documents prepared for the project are not intended to represent a statement regarding the legal applicability of NEPA to remedial actions conducted under CERCLA. In accordance with the integrated CERCLA/NEPA approach, a remedial investigation/feasibility study-environmental assessment (RI/FS-EA) is being conducted to evaluate conditions and potential responses for the quarry residuals operable unit (QROU). This operable unit consists of the following areas and/or media: the residual material remaining at the Weldon Spring quarry after removal of the pond water and bulk waste; underlying groundwater; and other media located in the surrounding vicinity of the quarry, including adjacent soil, surface water, and sediment in Femme Osage Slough. This work plan identifies the activities within the RI/FS-EA process that are being proposed to address contamination remaining at the quarry area.
