LIM <br /> Monitoring of Drainage Flows <br /> Monitoring of the storm drain for TPH, BTX and E as proposed <br /> would consist of: <br /> 1. Limit the discharge of the stripping tower to obtain a <br /> dilution rate of not less than 1:1 at the intersection <br /> of "D' Street with Fremont Street. <br /> This appears feasible even during the summer due to the <br /> surface discharges from the cannery area to the north <br /> r- of Teichert. <br /> 2. Monitor the TPH, BTX & E of the storm drain before the <br /> striipper flow enters the system at Weber Street. <br /> 3. Monitor the TPH, BTX & E at Fremont Street before it <br /> enters the 48' line in Fremont Street. <br /> 4. Monitor Fremont Street upstream of the 'D' Street <br /> discharge to Fremont. <br /> The proposed limits of discharge from the stripping tower to <br /> the 48' storm drain in Fremont Street are: <br /> TPH 5 PPM above background level <br /> Benzene Non-detNctable above background level <br /> .- Toluene Non-detectable above background level <br /> Xylene Non-detectable above background level <br /> Non-detectable above background level <br /> The objective of the storm drain monitoring by using <br /> dilution is to obtain a non-detectable increase in TPH, BTX & E <br /> above background levels in Fremont Street. <br /> t The discharge water will be tested for TPH, B, T, X, & E on <br /> a weekly- basis for the first six weeks, and monthly thereafter. <br /> The proposed levels of treatment for discharge `are those <br /> established by the Department of Health Services for drinking <br /> water standards for an aquifer: <br /> a <br /> Level of Treatment Detection Limit <br /> TPH Non-Detectable 10 ppm <br /> Benzene Non-Detectable 0.5 ppb <br /> --- Toluene Non-Detectable 100 ppb f ` <br /> Xylene Non-Detectable 620 ppb <br /> — -- —- - -Hthylbenzene - -Nan-Det ectable- T--------- 680 ppb <br /> -9- <br />
