Table 14. Footnotes for Influent and Effluent Monitoring Tables 12 and 13 <br /> Footnote Information <br /> a Take effluent samples for the CBOD5 analysis before or after the disinfection <br /> process. If taken after disinfection and chlorine is used, dechlorinate and <br /> reseed the sample. <br /> b 2/week means two (2) times during each week <br /> c 1/month means one (1) time during each month <br /> d Quarterly sampling periods are January through March, April through June, <br /> July through September, and October through December. The Permittee <br /> must begin quarterly monitoring for the quarter beginning on 1/1/22 4/1/22 7/1/22 <br /> 10/1/22 and submit results by 4/15/22, 7/15/22, 10/15/22, 1/15/22. <br /> e 24-hour composite means a series of individual samples collected over a 24- <br /> hour period into a single container, and analyzed as one sample. <br /> f Report daily flows only on days when collecting total ammonia and nitrate plus <br /> nitrite samples. <br /> g TIN (mg/L) as N = Total Ammonia (mg/L as N) + Nitrate plus Nitrite (mg/L as N) <br /> h Calculate mass concurrently with the respective concentration of a sample, <br /> using the following formula: <br /> Concentration (in mg/L) X daily flow (in MGD) X Conversion Factor (8.34) = <br /> lbs/day <br /> Calculate the monthly average total inorganic nitrogen load (lbs as N) using the <br /> following equation: <br /> Monthly average TIN load (lbs as N) <br /> = ((I Calculated TIN loads (—day lbs <br /> as N)) <br /> /number of samples)x number of days in the calendar month <br /> j Calculate the annual total inorganic nitrogen, year to date using the following <br /> calculation: <br /> Annual TIN load (lbs as N) = Monthly average TIN loads,to date <br /> k Or other equivalent EPA-approved method with the same or lower quantitation <br /> level <br /> The Permittee must ensure laboratory results comply with the quantitation level <br /> (QL) specified in the table. However, if an alternative method from 40 CFR Part <br /> 136 is sufficient to produce measurable results in the sample, the Permittee <br /> may use that method for analysis. If the Permittee uses an alternative method it <br /> must report the test method and QL on the discharge monitoring report. If the <br /> permittee is unable to obtain the required QL due to matrix effects, the <br /> Permittee must report the matrix-specific method detection level (MDL) and QL <br /> on the DMR. The permittee must also upload the QA/QC documentation from <br /> the lab on the QL development. <br /> Puget Sound Nutrient General Permit Page 34 <br />
