(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 M.A.C. R 323.2311(2), whichever is later, an existing non-domestic 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 M.A.C. R 323.2310(2). At least 90 days prior to commencement of discharge, new sources, and sources that become non-domestic users subsequent to the promulgation of an applicable categorical pretreatment standard, shall submit the reports to the POTW as required by M.A.C. R 323.2310(2). Any changes to the information required to be submitted by a non-domestic user pursuant to M.A.C. 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 non-domestic user subject to categorical pretreatment standards and requirements shall submit the reports to the POTW required by M.A.C. R 323.2310(3).
(C) Periodic reports on continued compliance.
(1) Any non-domestic 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 M.A.C. R 323.2310(4).
(2) These periodic reports shall be submitted at least once every six months (during the months of June and December unless alternate months are approved by the POTW), unless required more frequently by the applicable pretreatment standard, by the POTW, or by the state.
(3) The reports shall include a record of all average and maximum daily flows during the prior six-month 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 non-feasibility, to accept verifiable estimates of the average and maximum flows estimated using techniques approved by the POTW. The combined waste stream 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 waste stream. 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. In cases where the pretreatment standard requires compliance with a best management practice (or pollution prevention alternative), the user shall submit documentation required by the POTW or the pretreatment standard necessary to determine the compliance status of the user.
