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 Part 403.6(a)(4), whichever is later, existing CIUs subject to such pretreatment standards currently discharging to or scheduled to discharge to the city’s sanitary sewer system shall submit to the director a report which contains the information listed below.
At least ninety (90) days prior to commencement of discharge, new sources, and sources that become CIUs subsequent to the promulgation of an applicable categorical pretreatment standard shall submit to the director a report which contains the information listed below. A new source shall report the method of pretreatment it intends to use to meet the applicable pretreatment standards, an estimate of its anticipated flow, and an estimate of the quantity of pollutants to be discharged.
Users described above shall submit the following information:
2. Measurement of pollutants.
a. The user shall provide the information required in section 15.40.175(7);
b. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this paragraph.
c. Samples should be taken immediately downstream from pretreatment facilities, if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewater are mixed with the regulated wastewater prior to pretreatment, the city should measure the flows and concentrations necessary to allow the use of the combined wastestream formula (40 CFR Part 403.6(e)) to evaluate compliance with the pretreatment standards. Where an alternative concentration or mass limit has been calculated in accordance with 40 CFR Part 403.6(e) this adjusted limit along with supporting data shall be submitted to the city.
d. Sampling and analysis shall be performed in accordance with section 15.40.430.
e. The baseline monitoring 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 city’s sanitary sewer system.
3. Compliance Certification. A statement, reviewed and signed by the user’s authorized representative and certified by a qualified professional, indicating whether pretreatment standards and requirements are being met on a consistent basis, and, if not, whether additional operations and maintenance and/or pretreatment is required to meet the pretreatment standards and requirements.
4. Compliance Schedule. If additional pretreatment and/or operations and maintenance will be required to meet the pretreatment standards and requirements, the shortest schedule by which the user will provide such additional pretreatment and/or operations and maintenance must be provided. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard or requirement. A compliance schedule pursuant to this section must meet the requirements of section 15.40.320 of this chapter.
5. Signature and Report Certification. All baseline monitoring reports must be certified in accordance with section 15.40.180 of this chapter and signed by an authorized representative.
