WASTE DISCHARGE REQUIREMENTS -8- DEFENSE DISTRIBUTION REGION WEST TRACY SAN JOAQUIN COUNTY d. Authorized factory representatives' certifications that IRM components are properly installed. e. A revised "Start-up Schedule" for the start-up of the interim ground water cleanup system. 4. The Discharger shall submit to the Board and the Department of Health Services the "Prove-out Of System" report for approval at least two weeks prior to the proposed commencement of full scale operation of the interim ground water cleanup system. This report shall document compliance with Discharge Specifications C.1, C.2, and C.3. In addition, this report shall include a performance evaluation of the interim ground water cleanup system, based upon the data collected during the start-up and prove-out (per the attached Monitoring and Reporting Program No. 90-275). The objective of the performance evaluation is to determine the ability, reliability, and associated 0&M costs of the air stripper system in meeting: (1) the 1.0 ppb TCE and PCE effluent limitations in this Order, and (2) the non-detectable levels of TCE and PCE of 0.12 and 0.03, respectively, (per EPA Test Method 8010) . Furthermore, this evaluation must indicate the operational parameters necessary to maximize VOC removal efficiencies. Full scale operation shall not commence until the Board determines that the proposed system will adequately treat all identified pollutants, that the system will comply with waste discharge requirements, that the air stripper shall be operated to maximize VOC removal efficiencies, and that its continued operation is appropriate. 5. The Discharger shall submit a Technical Report to the Board and the Department of Health Services, prior to the end of the fourth month of full scale operation of the air stripper, which includes an analysis of the waste characterization data collected during the first three month operational period (Plan C monitoring within the attached Monitoring and Reporting Program No. 90-275) . This report shall include a summary of the data and a determination if the influent and/or effluent to the air stripper contains previously unidentified constituents of sufficient magnitude to either pose a threat to water quality and/or affect the treatment effectiveness of the air stripper. In addition, in the event that significant levels of previously unidentified pollutants are detected, this report shall include recommendations on the continued operation of this ground water treatment system, possible treatment plant modifications, and an assessment of the impacts to the beneficial uses of the receiving water due to this discharge.
