The Work Plan has been prepared to allow Baker staff and subcontractors employ the appropriate procedures and protocols for collection and analysis of environmental samples and evaluation of the resulting data. The Work Plan also describes the management and staffing of this project as well as the project schedule. Information concerning the operational history, waste characteristics and quantities, site description, and previous investigations summarized in the Work Plan is presented in detail in: • Revised Draft Final Remedial Investigations/Streamlined Risk Evaluation, F. E. Warren AFB Atlas "E" Missile Site 12, Windsor, Colorado (Baker, June 2001). • Final Site Investigation Report, F. E. Warren AFB Atlas "E" Missile Site 12, Windsor, Colorado (Baker, April 1998). 1.1 Purpose The primary purpose of this work is to collect additional data prior to the initiation of a Feasibility Study based on the recommendations of the RI/SRE, the Colorado Department of Public Health and Environment (CDPHE), US Army Corps of Engineers-Omaha District (USAGE) and USEPA Region VIII. The Work Plan outlines the tasks that will be implemented to support the future development and evaluation of appropriate remedial alternatives for various areas of concern at Site 12. The Work Plan provides guidance for field activities by describing in detail the sampling and data collection methods to be used to implement the various field tasks. The Work Plan also helps to ensure that sampling and data collection activities are carried out in accordance with regulatory guidance and accepted professional practice so that data obtained during the field activities are of sufficient quantity and quality to evaluate the nature and magnitude of contamination in various media and determine which areas may require further action. H:\_USACE_Oniaha_20717\Windsorworlcplans\DaiaGathCTing_FINAL\WorkPlan\DataGathWP-12.doc 1-1 1.2 Document Organization The Work Plan generally follows the previous work plans for Site 12; however, this Work Plan has been modified (streamlined) slightly to take into account the information available in the Site Investigation (SI) and Remedial Investigations/Streamlined Risk Evaluation (RI/SRE) Work Plans and the Revised Draft Final RI/SRE Report. Section 1.0 of the Work Plan identifies the purpose and the contents of the plan. Section 2.0 provides general background information. Section 3.0 provides the Field Sampling and Analysis Plan (FSAP) including a description of the sample locations and frequencies and provides a general technical approach for specific field and QA/QC activities. Section 4.0 provides the sample designation procedure. Detailed investigation procedures and sample handling and analytical requirements are provided in Section 5.0 and 6.0, respectively. Section 7.0 describes the site management and field reporting requirements. Section 8.0 describes the Summary Data Gathering Report. Section 9.0 describes the project management and staffing. Section 10.0 includes the project schedule and references are provided in Section 11.0.
