13.08.170 Baseline monitoring reports.
A. Within either one hundred eighty 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 shall submit to the director a report containing the information listed in subsection C of this section.
B. At least ninety days prior to commencement of their discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical standard, shall submit to the director a report containing the information listed in subsection C of this section. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source shall also give estimates of its anticipated flow and quantity of pollutants to be discharged.
C. IUs described above shall submit the information set forth below:
1. Identifying Information. The IU shall submit the name and address of the facility including the name of the operator and owners.
2. Permits. The IU shall submit a list of any environmental control permits held by or for the facility.
3. Description of Operations. The IU shall submit a brief description of the nature, average rate of production, and standard industrial classification of the operation(s) carried out by such IU. This description shall include a schematic process diagram that indicates points of discharge to the POTW from the regulated processes.
4. Flow Measurement. The IU shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:
a. Regulated process streams; and
b. Other streams as necessary to allow use of the combined waste stream formula of 40 CFR 403.6(e). The city may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.
5. Measurement of Pollutants.
a. The IU shall identify the pretreatment standards applicable to each regulated process; and
b. The IU shall submit the results of sampling and analysis identifying the nature and concentration of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration shall be reported. The sample shall be representative of daily operations.
c. A minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organics. For all other pollutants, twenty-four-hour composite samples must be obtained through flow-proportional composite sampling techniques where feasible. The city may waive flow-proportional composite sampling for any IU that demonstrates that flow-proportional sampling is infeasible. In such cases, samples may be obtained through time-proportional composite sampling techniques or through a minimum of four grab samples where the IU demonstrates that this will provide a representative sample of the effluent being discharged.
d. The IU shall take a minimum of one representative sample to compile the data necessary to comply with the requirements of this section.
e. Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment facility exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the IU shall measure the flows and concentrations necessary to allow use of the combined waste stream formula of 40 CFR 403.6(e) in order to evaluate compliance with the pretreatment standards. Where an alternate concentration has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the city.
f. Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto. Where 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the director determines that the 40 CFR Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the city or other parties, and approved by the director.
g. The city may allow the submission of a baseline report that utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.
h. The baseline report shall indicate the time, date, and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.
6. Compliance Certification. The IU shall submit a statement, reviewed by an authorized representative of the IU (as defined in Section 13.08.160 and certified to by a qualified professional) indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) and/or additional pretreatment is required for the IU to meet the pretreatment standards and requirements.
7. Compliance Schedule. If additional pretreatment and/or O and M will be required to meet the pretreatment standards, the IU shall submit the shortest schedule by which the IU will provide such additional pretreatment and/or O and M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule shall meet the requirements set forth in Section 13.08.180.
8. All baseline monitoring reports must be certified in accordance with this section and be signed by an authorized representative as defined in Section 13.08.160. (Ord. 1598 § 1 (part), 2014)
