b. Design parameters including "Applicable or Relevant and Appropriate <br /> Requirements" (ARARs) , and design restrictions, including permits; <br /> 3. 1.2 Work Plan. The AE shall prepare and submit a remedial design <br /> work plan as described in paragraph 4.2.2 of reference 10.14 which addresses, <br /> as a minimum, the following: <br /> a. Composition of the Design Team; <br /> b. Health and Safety Program for Field Activities; <br /> C. Requirements for additional field data collection; <br /> d. Requirements for extraction/injection well evaluation; <br /> e. Design Schedule; <br /> f. Design criteria and assumptions; and <br /> g. Proposed Treatment schemes. <br /> The AE shall submit versions of this document in accordance with the require- <br /> ments of Section 4.0 and the schedule provided in Section 5.0 of this sow. <br /> 3.2 General Design Requirements The engineering reports that the AE <br /> prepares as part of the remedial design will consist of three kinds of docu- <br /> ments; (1) design documents consisting of plans and specifications for con- <br /> structing the selected remedy, (2) written plans that describe how the <br /> remedial action will be implemented and monitored, and (3) a "Services Con- <br /> tract" work statement that contractually describes how the facility will be <br /> constructed, operated, and evaluated. <br /> 3.3 Groundwater Remedial Design The AE shall perform remedial design <br /> of the selected remedy that withdraws groundwater containing contaminants at <br /> levels equal to or greater than those established in the ROD, treats the con- <br /> taminated groundwater, and returns the treated groundwater to the aquifer or <br /> holding pond. The ROD has defined the groundwater contamination as operable <br /> unit one (OUl) . The system designed by the AE shall include all components <br /> and actions necessary to accomplish treatment of contaminated groundwater to <br /> the effluent levels established in the ROD for OU1. Aquifer pump tests have <br /> been performed at the site but uncertainties still exist as to the aquifer's <br /> characteristics. The intent of this SOW is that the system design use the <br /> available information and that provisions be made in system design to allow <br /> for the installation of additional wells and/or adjustments in the pumping <br /> rates of wells and treatment plant capacity to optimize system operation. <br /> AA-3 <br />
