A -- REMEDIAL DESIGN FOR THE TECHNICAL SUPPORT FACILITY INJECTION WELL (TSF-05) AND SURROUNDING GROUNDWATER CONTAMINATION (TSF-23) Contact Mr. Mike C. Stone. Lockheed Idaho Technologies Company (LITCO), P.O. Box 1625, Idaho Falls, ID 83415-3521; a management and operating contractor for the Department of Energy at the Idaho National Engineering Laboratory (INEL). TEST AREA NORTH (TAN) REMEDIAL DESIGN FOR THE TECHNICAL SUPPORT FACILITY INJECTION WELL (TSF-05) AND SURROUNDING GROUNDWATER CONTAMINATION (TSF-23). The INEL, Lockheed Idaho Technologies Company (LITCO) seeks sources for conduct of Treatability Studies to support evaluation of certain new or innovative technologies as potential replacement for conventional pump and treat remediation of a contaminated aquifer. The Waste Area Group 1 (WAG-1) Operable Unit 1-07B Record of Decision (OU 1-07B ROD, August 18, 1995), identifies conventional pump and treat remediation for both the hotspot (defined as groundwater with TCE concentrations greater than 5,000 ug/L) and the dissolved phase plume (defined as groundwater with TCE concentrations between 5,000 and 5 ug/L). The OU 1-07B ROD also identifies five technologies to be evaluated through the treatability study process (EPA 540/2-89-058) to determine if one or a combination of these technologies will be more effective in meeting remedial action objectives (RAOs). The five technologies are: 1) In Situ Enhanced or Augmented Biodegradation, 2) Zero Valent Metal Enhanced Dehalogenation, 3) Chemical Oxidation, 4) Natural Attenuation, and 5) Grout Curtain Containment of the Hotspot. The RAOs are: 1) Restore the dissolved phase plume to MCLs within 100 years, 2) Treat or contain the hotspot to prevent contaminant releases above MCLs, 3) Alternative technology lifecycle cost must be less than or equal to the default pump and treat lifecycle cost. The objective of the requested services will be to provide technical expertise to perform or supplement LITCO directed Bench Scale treatability studies (as defined in EPA 540/2-89-058) as a single or as any combination of the five technologies. The successful offeror(s) will provide technology specific expertise and technical support in the form of test plan development and bench scale experiment design, testing, documentation, and reporting. The bench scale studies will provide data and information to be used for independent evaluation of each technology. The independent evaluation will result in a selection and recommendation of one or more technologies to proceed to pilot scale. The period of performance for the proposed bench scale treatability studies is expected to run through July 1997 and pilot scale is expected to be complete by September 1998. The location of performance shall be either a) INEL, or b) the offeror's site as appropriate. The requested services will be focused on development of one or a combination of the five technologies at the bench scale. Offeror(s) that demonstrate a single or a combination of the five technologies is ready for pilot scale implementation will not be precluded from participating in subsequent follow-on procurements for the design and construction of pilot scale components or systems needed to complete the evaluation against conventional pump and treat remediation. The successful offeror(s) will not be precluded from participating in subsequent follow-on procurements for design and construction of a full scale implementation of one or more technologies should the pilot scale evaluation indicate the implementation will be more effective in meeting RAOs. The TSF-05 injection well is completed at 310 ft in a fractured rock aquifer and has been shown to act as the secondary source for a trichloroethene (TCE) plume that presently extends 10,000 feet down gradient at concentrations ranging from 20,000 ug/L at the injection well to less than 5 ug/L at the distal end of the plume. Although TCE is the primary contaminant of concern, additional groundwater contaminants include tetrachloroethene (PCE), cis- and trans-1,2-dichloroethene (cis-, trans-1,2-DCE), Sr-90, H-3, Cs-137, and U-234. The following evaluation criteria are generally applicable to a single or a combination of the five technologies. The following criteria will be evaluated to determine new or innovative technology performance improvement over conventional pump and treat effectiveness and overall remediation timeframe: 1) Demonstrate that the technology is capable of reducing known concentration of chlorinated hydrocarbons to MCLs, 2) Determine the single pass treatment efficiency, 3) Determine intermediate/degradation products and assess potential risk, 4) Determine reaction kinetics under ambient site conditions, 5) Identify process secondary waste streams and assess disposal options (volume, risk, cost), 6) Identify scale-up criteria and recommend pilot scale design, 7) Evaluate processes or site conditions that affect technology performance (e.g. T, pH, dissolved oxygen, competing ions), 8) Evaluate technology implementation health and safety issues and assess mitigating measures. The formal solicitation will require that offerors MUST clearly demonstrate the ability to meet the Qualification Criteria listed below. In addition, prospective sources responding to this announcement MUST submit a short (two to three page) discussion providing a general statement of qualification that addresses the following Qualification Criteria: 1) propose to perform one or a combination of the five treatability studies identified above, 2) demonstrate relevant technical experience in one or a combination of the five treatability study areas, 3) demonstrate availability of facilities and technical staff to complete the work within the period of performance, 4) demonstrate the ability to conduct a bench study using TSF-05 groundwater (a hazardous mixed low-level waste containing VOCs, H-3, Sr-90, Cs-137, U-234, 4,500 pCi/L gross beta, 0.4 pCi/L gross alpha, 3,200 pCi/L gross gamma), 5) demonstrate cost and schedule performance on similar projects as well as successful completion under controlled quality assurance and safety programs. Qualifying firms are invited to respond in writing with an expression of interest in participating in the TAN OU 1-07B Treatability Study procurement and are required to provide a two to three page statement of qualifications with respect to the foregoing criteria. Responses are required on or before December 11, 1995. LITCO will determine qualifying firms based on responses to this announcement and those firms that do not meet the qualification criteria will not be issued a Request for Proposal. Telephone responses will not be accepted. This notice is to assist LITCO in determining the potential for competition; no solicitation is currently available. Responses need to be addressed to Mr. Mike Stone, LITCO, P.O. Box 1625, Idaho Falls, ID 83415-3521, or fax (208) 526-7744. (325)
