Sec. 28-44.7. Categorical industrial user baseline monitoring requirements.
A. At least 90 days prior to commencement of discharge, new sources and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical standard must submit a report to the Director that contains the information listed in subsection C of this section. In addition, a new source must report the method of pretreatment it intends to use to meet applicable categorical pretreatment standards and estimates of its anticipated flow and quantity of pollutants to be discharged.
B. 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 403.6(a)(4), whichever is later, existing categorical industrial users currently discharging to or scheduled to discharge to the POTW must submit to the Director a report that contains the information listed in subsection C of this section.
C. Categorical industrial users described above must submit the following information:
1. The name and address of the facility, including the name of the operator and owner;
2. Contact information, description of activities, facilities, and plant production processes on the premises;
3. A list of any environmental control permits held by or for the facility;
4. A brief description of the nature, average rate of production (including each product produced by type, amount, processes, and rate of production), and Standard Industrial Classifications of the operation(s) carried out by such user; this description should include a schematic process diagram, which indicates points of discharge to the POTW from the regulated processes;
5. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined waste stream formula set out in 40 CFR 403.6(E);
6. Information regarding the measurement of pollutants including:
a. The categorical pretreatment standards applicable to each regulated process and any new categorically regulated processes for existing sources;
b. The results of sampling and analysis identifying the nature, concentration, and mass of regulated pollutants in the discharge from each regulated process where required by the pretreatment standard or by the Director;
c. Instantaneous, daily maximum, and long-term average concentrations or mass where required must be reported;
d. The sample must be representative of daily operations and must be analyzed in accordance with procedures set out in Section 28-44.3; where the pretreatment standard requires compliance with a BMP or pollution prevention alternative, the user must submit documentation as required by the Director or the applicable pretreatment standards to determine compliance with the standard;
e. The categorical industrial user must take a minimum of one representative sample to compile the data necessary to comply with the requirements of this subsection;
f. If pretreatment facilities exist, samples must be taken immediately downstream or immediately downstream from the regulated process if no pretreatment exists; if other wastewaters are mixed with the regulated wastewater prior to pretreatment, the categorical industrial users must measure the flows and concentrations necessary to allow use of the combined waste stream formula in 40 CFR 403.6(e) to evaluate compliance with the pretreatment standards; where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e), this adjusted limit along with supporting data must be submitted to the Director;
g. Sampling and analysis must be performed in accordance with Sections 28-44.3 and 28-44.4;
h. The Director may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures; and
i. The baseline report must indicate the time, date, and place of sampling and methods of analysis, and must certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW;
7. A statement, reviewed by the industrial user’s authorized representative as defined in Section 28-44.1 and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance and/or additional pretreatment is required to meet the pretreatment standards and requirements;
8. If additional pretreatment and/or operation or maintenance is required to meet the pretreatment standards, the shortest compliance schedule by which the industrial user will provide such additional pretreatment and/or operation and maintenance must be provided to the Department; the completion date in this schedule must not be later than the compliance date established for the applicable pretreatment standard; a compliance schedule pursuant to this section must meet the requirements set out in Section 28-44.5(F);
9. All baseline monitoring reports must be certified in accordance with Section 28-44.1 and signed by an authorized representative as defined in Section 28-44.1. (Ord. No. G-6740, § 1, 2020)
