Current through Register Vol. 49, No. 24, December 9, 2024
Part 7049.0520 - CONTENTS OF BASELINE MONITORING REPORT
Subpart 1.Baseline monitoring reports.

Baseline monitoring reports must include the information in this part. New sources must include in the report information describing the method of pretreatment the source intends to use to meet applicable categorical pretreatment standards. New sources shall give estimates of the information requested in subparts 5 and 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.Permits.

The industrial user shall submit a list of any environmental control permits held by or for the facility.

Subp. 4.Description of operations.

The industrial user shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operations carried out by the industrial user. The description shall include a schematic process diagram that indicates points of discharge to the POTW from the regulated processes.

Subp. 5.Flow measurement.

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

Subp. 6.Measurement of pollutants.

The industrial user shall:

A. identify the categorical pretreatment standards applicable to each regulated process; and
B. submit the results of sampling and analysis identifying the nature and concentration, or mass, when required by the categorical standard or by the control authority, of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration, or mass, when required, shall be reported. The sample shall be representative of daily operations. In cases where the categorical pretreatment standard requires compliance with a best management plan or pollution prevention alternative, the industrial user shall submit documentation as required by the control authority or the applicable categorical pretreatment standards to determine compliance with the standard.
Subp. 7.Certification.
A. 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 and, if not, whether additional operation and maintenance or additional pretreatment is required for the industrial user to meet the categorical pretreatment standards and requirements. 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 7049.0480, subpart 2, at the time the industrial user submits the baseline monitoring reports, the certification and the compliance schedule in part 7049.0550 pertain to the modified limits.
B. 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.
C. When the POTW performs the required sampling and analysis in lieu of the categorical industrial user, the categorical industrial user is not required to submit the compliance certification under this subpart.
