The county may sample and analyze user discharges in lieu of requiring the users to conduct sampling and analysis as follows:
(a) All significant industrial users shall, at a frequency determined by the director but in no case less than once every six months, submit a report indicating the nature and concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. Sampling and analysis must be performed in accordance with procedures set out in section 24-200 and 24-201. All periodic compliance reports must be signed and certified in accordance with section 24-172(d) of this ordinance.
(b) All wastewater samples must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(c) If a user subject to the reporting requirement in this section monitors any pollutant more frequently than required by the director, using the procedures prescribed in section 24-200, the results of this monitoring shall be included in the report.
