(A)   All significant industrial users shall, at a frequency determined by the city manager, but in no case less than twice per year (in June and December), submit a report indicating the nature and concentration of pollutants in the discharge that are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a BMP or pollution prevention alternative, the user must submit documentation required by the city manager of the pretreatment standard necessary to determine the compliance status of the user. All periodic compliance reports must be signed and certified in accordance with section 19-55 of this article.
   (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 city manager, using the procedures prescribed in section 19-79 of this article, the results of this monitoring shall be included in the report sent to the city manager.
