(a) Baseline Monitoring Reports. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made upon a category determination submission under MAC R 323.2311(2) whichever is later, an existing nondomestic user subject to the categorical pretreatment standards and that currently discharges or is scheduled to discharge to the POTW shall submit a report to the POTW as required by MAC R 323.2310(2). At least 90 days prior to commencement of discharge, new sources, and sources that become nondomestic users subsequent to the promulgation of an applicable categorical pretreatment standard shall submit the reports to the POTW as required by MAC R 323.2310(2). Any changes to the information required to be submitted by a nondomestic user pursuant to MAC R 323.2310(2)(a) through (e) shall be submitted by the User to the POTW within 60 days of when the User becomes aware of the change.
(b) Reports on Compliance with Categorical Pretreatment Standard Deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standard or, in the case of a new source, following commencement of the discharge to the POTW, any nondomestic user subject to categorical pretreatment standards and requirements shall submit the reports to the POTW required by MAC R 323.2310(3).
(c) Periodic Reports on Continued Compliance. Any nondomestic user subject to a categorical pretreatment standard, after the compliance date of the categorical pretreatment standard, or, in the case of a new source, after commencement of the discharge into the public sewer or POTW, shall submit the periodic reports to the POTW required by MAC R 323.2310(4). These periodic reports shall be submitted at least once every six months (during the months of April and October unless alternate months are approved by the POTW), unless required more frequently by the applicable pretreatment standard, by the POTW, or by the state. The reports shall include a record of all average and maximum daily flows during the reporting period, except that the POTW may require more detailed reporting of flows. All flows shall be reported on the basis of actual measurement unless the POTW agrees, due to cost or nonfeasibility, to accept reports of average and maximum flows estimated using techniques approved by the POTW. The combined wastestream formula may be used for reporting purposes after the initial information has been furnished to the POTW, provided there has been no change to the elements composing the combined wastestream. The results of sampling of the discharge and analysis of pollutants appearing in the report shall be cross-referenced to the related flow and mass to determine compliance with National Categorical Pretreatment Standards.
