MONITORING AND REPORTING PROGRAM 2 <br /> CITY OF MANTECA AND CITY OF LATHROP <br /> WASTEWATER QUALITY CONTROL FACILITY <br /> SAN JOAQUIN COUNTY <br /> Sampling <br /> Constituents UniLs Type of Sample Frequency <br /> Chlorine Residual' mg/1 Grah: Daily <br /> Temperature °F/°C Grab Daily <br /> Flow MGD Cumulative Continuous <br /> Oil and Grease' mg/l Grab Weekly <br /> Nitrate (as N) mg/l Grab Weekly <br /> Ammonia (as N)' mg/I Grab Weekly <br /> ' Test procedures to follow the latest version of EPA/600/4-90/027, using fathead minnows or golden <br /> shiners. <br /> 2 Standard minerals include Total Dissolved Solids, Electrical Conductivity, Chloride, Sulfate, Nitrate, <br /> Bicarbonate Alkalinity, Carbonate Alkalinity, Calcium, Magnesium, Potassium, Sodium, pH, and <br /> Hardness. <br /> If the discharge is intermittent rather than continuous, then on the first day of each such intermittent discharge, <br /> the Discharger shall monitor and record data for all of the constituents listed above, after which the frequencies <br /> of analysis given in the schedule shall apply for the duration of each such intermittent discharge. In no event <br /> shall the Discharger be required to monitor and record data more often than twice the frequencies listed in the <br /> schedule. <br /> EFFLUENT MONITORING OF RECLAMATION RATER <br /> Effluent samples shall be collected downstream from the last connection through which reclaimed water and <br /> sludge can be admitted into the field distribution system. Effluent samples should be representative of the <br /> volume and nature of the discharge. Samples collected from the outlet structure of ponds will be considered <br /> adequately composited. Time of collection of a grab sample shall be recorded. The following shall constitute <br /> the effluent monitoring program: <br /> Sampling <br /> Constituents Units Type of Sam lie Frequency <br /> Flow mgd Continuous Daily <br /> 20°C BODS m9/1 Grab Twice Monthly <br /> Settleable Matter mUl Grab Twice Monthly <br /> Total Dissolved Solids mg/1 Grab Quarterly <br />
