Title: Remedial investigation Phase 2 supplemental work plan for the Hanford Site 1100-EM-1 Operable Unit

Abstract

The 1100 Area, the central warehousing, vehicle maintenance, and transportation operations center for the Hanford Site, was designated an (NPL) National Priorities List site in July 1989. This NPL site was divided into four operable units, and the first equipment maintenance operable unit, 1100-EM-1, was assigned the highest priority. The following summary focuses on the major issues related to contaminant sources, meteorology, surface hydrology, geology, pedology, hydrogeology, and ecology. The 110-EM-1 Phase 1 R1 report recommended further investigation at six waste management units assigned to or within the operable unit. 1100-1 (Battery Acid Pit)--an unlined dry sump, or french drain, used for the disposal of waste acid from vehicle batteries; 1100-2 (Paint and solvent Pit)--a former sand and gravel pit subsequently used for the disposal of construction debris and, reportedly, waste paints, thinner, and solvents; 1100-4 (Antifreeze Tank Site)--The site of a former underground storage tank used for the disposal of waste vehicle antifreeze; UN-1100-6 (Discolored Soil Site)--the location of an apparent disposal event onto the ground surface involving a container of organic waste liquids; Horn Rapids Landfill--a solid waste facility used primarily for the disposal of office and construction waste and the burning of classified documents; asbestos, sewage sludge,more » fly ash, and, potentially, drums of unidentified organic liquids alleged to be disposed at this location; and Ephemeral Pool--the location of 1100 Area parking lot runoff accumulation during infrequent, high-intensity precipitation events. This remedial investigation supplemental work plan details the efforts for final characterization of the 1100-EM-1 Operable Unit that will provide data to be used for the evaluation of remedial operations in the Phase 3 1100-EM-1 feasibility study. 19 refs., 28 figs., 2 tabs.« less

  • This work plan was initiated and prepared in accordance with US Environmental Protection Agency (EPA) guidance. It provides a description of the tasks required to complete the remedial investigation and feasibility study (RI/FS), which will identify appropriate remedial actions (RA). The tables indicate the section of this work plan where the information indicated can be obtained. This work plan is intended to address investigations and remediation of inactive waste sites within the 1100-EM-1 operable unit in the proposed 1100 National Priorities List (NPL) Aggregate Area. Additional RI/FS work plans will be prepared to address other operable units. 98 refs., 28more » figs., 22 tabs.« less
  • Four areas of the Hanford Site (the 100, 200,300, and 1100 Areas) have been included on the US Environmental Protection Agency's (EPA's) National Priorities List (NPL) under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). Under the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement, Ecology et al. 1990a), signed by the Washington State Department of Ecology (Ecology), EPA, and the US Department of Energy (DOE), more than 1,000 inactive waste disposal and unplanned release sites on the Hanford Site have been grouped into a number of source and groundwater operable units. These operable units containmore » contamination in the form of hazardous waste, radioactive/hazardous mixed waste, and other CERCLA hazardous substances. This work plan and the attached supporting project plans establish the objectives, procedures, tasks, and schedule for conducting the CERCLA remedial investigation/feasibility study (RI/FS) for the 100-FR-1 operable unit. The 100-FR-1 source operable unit is one of two source operable units in the 100-F Area. Source operable units include facilities and unplanned release sites that are potential sources of hazardous substance contamination. The groundwater affected or potentially affected by the entire 100-F Area is considered as a separate operable unit, the 100-FR-3 groundwater operable unit. A separate work plan has been initiated for the 100-FR-3 operable unit (DOE/RL 1992a).« less

  • A survey of technologies was conducted to provide information for a Data Quality Objectives process being conducted to support revision of the Remedial Investigation/Feasibility Study Work Plan for the 200-SW-2 Operable Unit. The technology survey considered remediation and characterization technologies. This effort was conducted to address, in part, comments on the previous version of the Remedial Investigation/Feasibility Study Work Plan for the 200-SW-2 Operable Unit as documented in 200­SW­1 and 200­SW­2 Collaborative Workshops-Agreement, Completion Matrix, and Supporting Documentation. By providing a thorough survey of remediation and characterization options, this report is intended to enable the subsequent data quality objectives andmore » work plan revision processes to consider the full range of potential alternatives for planning of the Remedial Investigation/Feasibility Study activities.« less
  • The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) focuses on waste site cleanups whenever there is a release or substantial threat of release to the environment by a hazardous substance, pollutant, or contaminant. Under such conditions, the US Environmental Protection Agency (EPA) is authorized to undertake removal and/or remedial action. As summarized in EPA guidance documents, a specific process has been established to identify potentially hazardous sites, characterize site contamination, assess treatment technologies, and then design and construct appropriate treatment facilities. An initial activity of the Remedial Investigation/Feasibility Study/Record of Decision (RI/FS/ROD) process is the issuance of a workmore » plan. The work plan for the 300-FF-5 groundwater operable unit on the Hanford Site is the topic of this document. This 300-FF-5 Work Plan is written as an addendum to the 300-FF-1 Work Plan. The 300-FF-5 operable unit consists of the groundwater aquifer beneath the 300-FF-1, 300-FF-2, and 300-FF-3 source operable units and adjacent areas defined by the extent of groundwater contamination (WHC 1989). The outline used in this addendum generally follows that of the 300-FF-1 Work Plan. This addendum is complete in its coverage of all outline sections, but where possible, the 300-FF-1 Work Plan is referenced rather than duplicating major discussions. 119 refs., 47 figs., 35 tabs.« less
