14.10.330 Periodic Compliance Reports.
A. The Director may specify the necessary minimum sampling and reporting frequencies and include applicable requirements in permits. Significant Industrial Users (SIUs) must:
1. Report at least twice a year, in June and December unless otherwise specified;
2. Report the flows and concentrations for the reporting period of regulated pollutants in all discharges subject to Pretreatment Standards;
3. Report average and maximum daily flows for the reporting period and identify where flow estimates are used; and
4. Include the documentation needed to show compliance with applicable BMPs, pollution prevention alternatives, maintenance, treatment, or record keeping requirements.
B. Users must sign and certify all periodic compliance reports in accordance with Section 14.10.430(A) of this Ordinance.
C. Users must take wastewater samples which are representative of their range of discharge conditions and of any discharge not disclosed in their permit application. Users must properly operate, clean, and maintain sampling and flow metering facilities and devices and ensure they function properly. The Director may not allow User claims that sampling results are unrepresentative due to a user’s failure to meet this requirement.
D. Users subject to the reporting requirements in this Section must report any additional monitoring which might determine compliance with permit requirements. This includes any additional monitoring of regulated pollutant at their respective effluent monitoring locations using procedures prescribed in Section 14.10.400 of this Ordinance. In such cases, the results of this monitoring shall be included in periodic monitoring reports. (Ord. M-3970 §2, 2010)
