<br />C. FOOTNOTES <br />• PART I <br />Page 4 of 19 <br />J When the most sensitive analytical method which complies with Part I.F.2. of the <br />permit has a detection limit greater than or equal to the permit limit, the <br />permittee shall report "less than the detectable limit," as appropriate. Such <br />reports shall not be considered as violations of the permit limit. <br />The present lowest method detection limits for specific parameters (which have <br />limitations which are, in some cases, less than or equal to the detection limit) <br />are as follows: <br />Total Residual Chlorine 0.05 mg/1 <br />Potentially Dissolved Cadmium 0.0003 mg/1 <br />Potentially Dissolved Copper 0.005 mg/1 <br />Potentially Dissolved Lead 0.005 mg/1 <br />Total Mercury 0.00025 mg/1 <br />Potentially Dissolved Nickel 0.05 mg/1 <br />Potentially Dissolved Silver 0.0002 mg/1 <br />Potentially Dissolved Zinc 0.05 mg/1 <br />Cyanide, Weak Acid Dissociable 0.030 mg/1 <br />Fecal coliform bacteria average concentrations shall be determined by the <br />geometric mean of all samples collected during a thirty (30) consecutive day <br />period. The 7 day average shall be determined by the geometric mean of all <br />samples taken during a seven (7) day period. <br />n/ The potentially dissolved metal fraction is defined in The Basic Standards and <br />Methodoloeies for Surface Water 3.1.0 (5 CCR 1002-81 as: that portion of a <br />constituent measured from the filtrate of a water and suspended sediment sample <br />that was first treated with nitric acid to a pH fo 2 or less and let stand for B <br />to 96 hours prior to sample filtration using a 0.4 or 0.45-UM membrane filter. <br />Note the "potentially dissolved" method cannot be used where nitric acid will <br />interfere with the analytical procedure used for the constituent measured. <br /> <br />amended effective <br />
