(a)
Within either 180 days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR Section 403.6(a)(4), whichever is later, existing industrial users currently discharging to or scheduled to discharge to the municipal wastewater system shall submit a report which contains the information listed in subsection (b) of this section. At least 90 days prior to commencement of their discharge, the owners, operators, permittees, and facility managers of new sources and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical pretreatment standard shall submit to the control authority a report which contains the following:
(b)
Baseline monitoring reports shall include the following information:
(1)
All information listed in FMC § 20.30.340(a)(1) through (a)(11); and
(2)
Measurement of Pollutants.
(A)
The industrial users shall take a minimum of one representative sample to compile the data necessary to comply with the requirements of this subsection;
(B)
Samples shall be taken immediately downstream from pretreatment facilities if such facilities exist or immediately downstream from the regulated processes if no pretreatment facilities exist. Industrial users shall measure the flows and concentrations necessary to allow use of the combined wastestream formula in 40 CFR Section 403.6(e) if other wastewaters are mixed with the regulated wastewater prior to pretreatment. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR Section 403.6(e) this adjusted limit along with supporting data shall be submitted to the control authority. Both daily maximum and average concentrations (where determined) shall be reported;
(C)
Sampling and analysis shall be performed in accordance with the sampling techniques described in this chapter and 40 CFR Part 136;
(D)
The control authority may allow the submission of a baseline monitoring report which uses historical data only, provided the data is sufficient to determine the need for industrial pretreatment measures;
(E)
The baseline report shall indicate the time, date, and place of sampling, and the methods of analysis. Industrial users shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the municipal wastewater system; and
