(a) All significant industrial users shall, at a frequency determined by the director but in no case less than twice per year (once in July covering the six-month period December 1 through May 31 and once in January covering the six-month period June 1 through November 30), submit a report containing at a minimum:
(1) The nature and concentration of pollutants in the discharge which are limited by pretreatment standards;
(2) The measured or estimated average and maximum daily flows for the reporting period;
(3) In cases where the pretreatment standard requires compliance with a best management practice or pollution prevention alternative, the user must submit documentation required by city or the pretreatment standard necessary to determine the compliance status of the user; and
(4) Contributing information as is determined necessary to account for water usage, materials recovery or disposal practices.
(b) All periodic compliance reports shall be signed and certified in accordance with § 12.5-633 of this article.
(c) All wastewater samples shall 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 equipment in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(d) 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 §§ 12.5-610.1, 12.5-610.2, 12.5-661, 12.5-641 and 12.5-663 of this article, the results of this monitoring along with chain-of-custody forms shall be included in the report.
