Pnlrr I <br />Pa_~e ~ ~~r Il <br />C. FOO'IlVO"1'IiS (continued) <br />h/ 'I'DS shall be sampled on a monthly basis until six samples have been analyzul. A sport of "No Discharge" shall <br />not be counted as one of the six samples. Thereafter, monitoring shall continue on a quarterly basis. Following <br />submittal of the initial six sets of monthly dale, the Division shell determine whether the permiltce is required to <br />submit a report addressing salt removal in accordance with Regulations For Implementation of the Colorado River <br />Salinity Standards Through the NPDES Permit Program, 3.10.0. If the salinity report is required, the Division shall <br />so advise the permittee by letter and the report shall be submitted within 180 days. <br />i/ This parameter is subject to "Noncompliance Notification" requirements of PaR II.A.3.(b)(v) of this permit. <br />j/ Procedure for determining settleable solids is contained in 40 CFR 434.64. The method detection limit for measuring <br />settleable solids under this part shall be 0.4 mUl. <br />k/ Should a precipitation event occur which is greater than the 10-yeaz, 24-hour event, the permittee shall submit rain <br />gauge or other appropriate documentation in order for an exemption to be claimed. In lieu of such documentation, <br />limitations contained in Part I.A.1.(b), shall apply. Documentation shall be reported az an attachment to the Discharge <br />Monitoring Report for the appropriate period. <br />I/ When the most sensitive analytical method which complies with PaR I.F.2. of the permit has a detection limit greater <br />than or equal to the permit limit, the permittee shall report "less than the detectable limit," az appropriate. Such <br />reports shall not be considered az violations of the permit limit. <br />The present lowest method detection limits for specific parameters (which have limitations which are, in some cases, <br />less thou or equal to the detection limit) are az follows: <br />Total Residual Chlorine 0.05 mg/1 <br />Total Recoverable Cadmium 0.0003 mg/( <br />Total Recoverable Copper 0.005 mg/I <br />Total Recoverable Lead 0.005 mg/l <br />Total Mercury 0.00025 mg/I <br />Total Recoverable Nickel 0.05 mg/I <br />Total Recoverable Silver 0.0002 mg/I <br />Total Recoverable Zinc 0.05 mg/I <br />Benzene, mg/1 0.001 mg/I <br />m/ Fecal coliform bacteria average concentrations shall be determined by the geometric mean of all samples collected <br />during a thirty (30) consecutive day period. The 7 day average shall be determined by the geometric mean of all <br />samples taken during a seven (~ day period. <br />n/ There shall be no acute tonicity in the effluent from this discharge point. The acute toxicity limitation is exceeded <br />if 1) a statistically significant difference in mortality (at the 95~ confidence level) is observed for either species <br />between the control and any dilution less that or equal to the identified IWC (33.9%). exceeds 50%u. <br />
