Mokelumne River Fish InstallPkn -3- 28 April 2000 <br /> Inspection Report <br /> Review of the SMRs for January and February 2000 revealed that the all of the deficiencies with the <br /> exception of flow measurements had been corrected. This deficiency was discussed with Mr. Bryant <br /> during the inspection. <br /> Mr. Bryant indicates that Discharge 001 (fish ladder) consists of water passing through the concrete <br /> rearing ponds and gravel ponds No. 1 and 2, while the Discharge 002 (24-inch diameter pipe) consists <br /> of water passing through the hatchery building and -ravel ponds No. 3 and 4. Order No. 97-116 <br /> defines Discharge 001 as hatchery building wastes and Discharge 002 as the rearing pond wastes. <br /> Effluent limits are the same for both discharge locations and historical SMRs have shown the quality of <br /> both effluents to be comparable. <br /> RWOCB SAMPLING AND ANALYSIS: <br /> To supplement the inspection, I collected influent, effluent and receiving water samples and submitted <br /> these samples for independent analytical testing. To compare my analytical results with those of the <br /> Discharger I used the same sampling locations as the Discharger. The samples were analyzed for all of <br /> the constituents required within the MRP. As part of the sample collection, I also conducted field <br /> screening for dissolved oxygen, temperature, pH, and electrical conductivity. The results of the field <br /> screening are summarized in Table 1. The results of the independent analytical testing are summarized <br /> within Table 2. <br /> Table 1, Results of Field Screening <br /> SAMPLE ID Dissolved 02 Temperature pH Conductivity <br /> /I <br /> m °C H Units mohs/cm <br /> Influent 10.04 11.2 7.34 46.6 <br /> Discharge 001 9.56 11.4 7.5 47 <br /> Discharge 002, Hatchery 10.91 11.2 7.32 46.4 <br /> Discharge 002, Pond 4 9.71 12.4 7.51 47.5 <br /> Receiving Water 8.73 12.4 7.36 49 <br /> Table 2,Summary of Analytical Results <br /> ANALYTICAL INFLUENT DISCHARGE DISCHARGE REC.WATER <br /> COMPOUNDS 001 002 <br /> Total Dissolved Solids (mg/I) 54 54 40 46 <br /> Total Suspended Solids (mg/1) <5 <5 <5 NS <br /> Settleable Solids (mUl) <0.1 <0.1 <0.1 NS <br /> Ammonia (mg/1) NS <0.5 <0.5 <0.5 <br /> Copper (pg/1) NS 1.7 2-4 2.6 <br /> 1 NS: The MRP does not require this sampling point to be analyzed for this constituent. <br /> 2 Ammonia is not required by the MRP to be analyzed. <br /> 3 No copper or other chemicals were reported or observed in use at time of inspection. <br />
