Chapter 7049 - WASTEWATER PRETREATMENT
Part 7049.0560 - 90-DAY COMPLIANCE REPORT

Subpart 1. General.

Within 90 days following the date for final compliance with applicable categorical pretreatment standards or, in the case of a new source, following commencement of the introduction of wastewater into a POTW, an industrial user subject to national categorical pretreatment standards and requirements shall submit to the control authority a report containing the information in subparts 2 to 6.

Subp. 2. Identifying information.

The industrial user shall submit the name and address of the facility, including the name of the operator and owners.

Subp. 3. Flow measurement.

The industrial user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the receiving POTW from regulated process waste streams and other streams as necessary to allow use of the combined waste stream formula in part 7049.0350. The control authority may allow for verifiable estimates of these flows when justified by cost or feasibility considerations.

Subp. 4. Measurement of pollutants.

The industrial user shall:

Subp. 5. Certification.

The industrial user shall submit a certification consisting of a statement, reviewed by an authorized representative of the industrial user, as provided in part 7049.0220, and certified by a qualified professional, indicating whether categorical pretreatment standards are being met on a consistent basis. If the industrial user's categorical pretreatment standard has been modified by a removal credit as provided in parts 7049.0360 to 7049.0470; the combined waste stream formula as provided in part 7049.0350; or a fundamentally different factors variance as provided in part 7049.0485, at the time the industrial user submits the 90-day compliance report, the certification and the compliance schedule in part 7049.0550 pertain to the modified limits. If an alternate concentration or mass limit has been calculated according to part 7049.0300, subpart 3, the adjusted limit and supporting data shall be included.

Subp. 6. Production rate reporting.

Industrial users subject to national categorical pretreatment standards with limits expressed in terms of allowable pollutant discharge per unit of production, or other measure of operation, shall submit information on their production rate. For industrial users subject to equivalent mass or concentration limits established by the control authority according to part 7049.0300, subpart 2, for categories with production-based categorical pretreatment standards, the report must contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to production-based categorical pretreatment standards, the report must include the user's actual production during the reporting period.
