Composite Yearly <br /> Standard minerals shall include all major cations and anions and include a verification that the analysis is <br /> complete (i.e., cation/anion balance). <br /> ' Report minimum and maximum pH excursions and the duration of excursions. Report the total time of <br /> excursions (within a reporting period) in percent time. <br /> 3 Report the magnitude and duration of all chlorine residual concentrations greater than zero within the reporting <br /> period. <br /> Concurrent with biotoxicity monitoring. <br /> ' Report as both Total and Un-ionized ammonia. <br /> ° The test species shall be fathead minnow (Pimephales promelas) with no pH or temperature adjustment, except <br /> as authorized by the Executive Officer. <br /> If the discharge is intermittent rather than continuous, then on the first day of each such intermittent <br /> discharge, the Discharger shall monitor and record data for all of the constituents listed above, after <br /> which the frequencies of analysis given in the schedule shall apply for the duration of each such <br /> intermittent discharge. In no event shall the Discharger be required to monitor and record data more <br /> often than twice the frequencies listed in the schedule. <br /> RECLAIMED WATER MONITORING <br /> All samples shall be grab samples, collected at the location where water is provided for the <br /> reclaimed water users. Reclaimed water monitoring shall include at least the following: <br /> Sampling <br /> Constituent Units Frequency <br /> Total Coliform Organisms MPN/100 ml Twice Weekly <br />
