Storm Water Sampling Points <br /> The permittees shall monitor storm water from the sampling points specified in the approved <br /> Storm Water Management Plan., <br /> 2. Storm Selection Criteria <br /> The permittees shall sample storms which are representative of climatic conditions within the <br /> area served by the MS4 as specified in the approved Storm Water Management Plan. <br /> 3. Monitoring Frequency and Parameters to be Monitored ' <br /> Sampling of storms shall be conducted three times within each twelve month period following <br /> permit issuance for the following parameters: <br /> Item or Parameter Type of Sample <br /> pH Grab <br /> Hardness Flow weighted composite <br /> 5 -Day Biochemical Oxygen Demand Flow weighted composite w• <br /> Total Suspended Solids Flow weighted composite <br /> Total Dissolved Solids Flow weighted composite <br /> Total phosphorous Flow weighted composite <br /> Ortho phosphorous Flow weighted composite <br /> Total Kjeldahl Nitrogen Flow weighted. composite <br /> Nitrate + Nitrite Nitrogen Flow weighted composite <br /> E. Coli bacteria Grab <br /> Total copper Flow weighted composite <br /> Total lead Flow weighted composite <br /> Total zinc Flow weighted composite <br /> Total cadmium Flow weighted composite <br /> 4. - Sampling Waiver <br /> In the event the permittee is unable to collect or analyze any sample or pollutant parameter due <br /> to circumstances beyond the permittee's control, a written explanation of the circumstances that <br /> prevented the collection or analysis shall be submitted to the Department in the annual report. <br /> The permittee shall exercise due diligence in collecting and analyzing all samples as required by <br /> Schedule B. Circumstances beyond the control of the permittee may include abnormal climatic <br /> conditions (e.g., fewer storms in the annual reporting period than typically are representative <br /> of climatic conditions);' weather conditions that, make the collection or analysis of samples unsafe <br /> or impracticable (e.g., storms of such intensity that sampling would present an unreasonable <br /> safety risk); or unavoidable equipment failures caused by weather conditions or other conditions <br /> ' beyond the control of the permittee (provided that operator error is not a condition beyond the <br /> control of the permittee). If more than one sampling event is missed at any stormwater sampling <br /> point, then re- sampling at that point will occur within twelve months of the second missed storm <br /> event. <br />
