WASTE DISCHARGE REQUANTS ORDER NO.R5-2002-0213 • 19 <br /> U.S.DEPARTMENT OF DEFENSE <br /> DEFENSE LOGISTICS AGENCY <br /> DEFENSE DISTRIBUTION DEPOT SAN JOAQUIN <br /> SHARPE GROUNDWATER REMEDIATION SYSTEM <br /> SAN JOAQUIN COUNTY <br /> a. In calculating for compliance, the Discharger shall count all non-detect measures at <br /> one-half of the detection level and apply the monthly average flow from the sampled <br /> discharge. If compliance with the effluent limit is not attained due to the non-detect <br /> contribution, the Discharger will improve and implement available analytical <br /> capabilities and compliance will be evaluated with consideration of the detection limits. <br /> b. After collecting the initial twelve months of data, twelve month mass loadings should <br /> be calculated for each calendar month. For monthly measures, calculate monthly <br /> loadings using average monthly flow and the average of all mercury analyses <br /> conducted that month(for each GWTP). After collecting the initial twelve months of <br /> data, the Discharger shall submit a cumulative total of mass loadings for the previous <br /> twelve months with each self-monitoring report. Compliance will be determined based <br /> on the previous 12-month moving averages over the previous twelve months of <br /> monitoring. <br /> 4. Survival of aquatic organisms in 96-hour bioassays of undiluted waste shall be no less <br /> than: <br /> Minimum for any one bioassay- - - - -- - - - 70% <br /> Median for any three or more consecutive bioassays - - - - 90% <br /> 5. Effluent shall not exceed the following limits: <br /> Daily Weekly 30 Day Monthly 12 Month <br /> Constituents Units Maximum Average Median Average Average <br /> Total Volatile Organic µg/l,(ppb) 1.0 <0.5 -- - <br /> Compounds lbs/day 0.016' 0.008' <br /> Total Petroleum gg/L(ppb) 100 <50 <br /> Hydrocarbons lbs/day 1.6' 0.8' <br /> Arsenic (Total) gg/L(ppb) 502 402 105 <br /> lbs/day 0.8',2 0.63'•2 0.16'5 <br /> Lead(Total) gg/L(ppb) 3.2' <br /> lbs/day 0.051'•' <br /> Mercury lbs/yr --- --- 0.042" <br /> ' Based upon maximum daily design treatment capacity of 1.9 mgd. <br /> 2 Interim limitation until 22 January 2006. <br /> ' Interim limitation pending additional data collection required by Provision E.2. <br /> Preliminary mass limitation until completion of Interim Mercury Mass Limitation <br /> Study of Provision E.3. <br /> 5 Effective 23 January 2006. <br />
