A. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision on a category determination under 40 C.F.R. 403.6(a)(4), whichever is later, existing significant industrial users subject to such categorical pretreatment standards and currently discharging to or scheduled to discharge to the municipal system shall be required to submit to the city a report which contains the information listed in division B., below. At least 90 days prior to commencement of their discharge, new sources, including existing users which have changed their operation or processes so as to become new sources, shall be required to submit to the city a report which contains the information listed in division B. A new
source shall also be required to report the method it intends to use to meet applicable pretreatment standards. A new source shall also give estimates of its anticipated flow and quantity of pollutants discharged.
B. The information required by this section includes:
1. Identifying information. The user shall submit the name and address of the facility including the name of the operator and owners;
2. Permits. The user shall submit a list of any environmental controls permits held by or for the facility;
3. Description of operation. The user shall submit a brief description of the nature, average rate of production, and standard industrial classifications of the operation(s) carried out by such industrial user. This description should include a schematic process diagram which indicates points of discharge to the system from the regulated processes;
4. Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the system from regulated process streams and other streams as necessary to allow use of the combined wastewater formula set out in 40 C.F.R. 403.6(e);
5. Measurement of pollutant.
a. The industrial user shall identify the categorical pretreatment standards applicable to each regulated process.
b. In addition, the industrial user shall submit the results of sampling and analysis identifying the nature and concentration (and/or mass, where required by federal, state or city standards) of regulated pollutants in the discharge from each regulated process. Instantaneous, daily maximum and long term average concentrations (or mass, where required by federal, state or city standards) shall be reported. The sample shall be representative of daily operations.
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 wastewaters are mixed with the regulated wastewater prior to pretreatment the user should measure the flows and concentrations necessary to allow use of the combined wastestream formula, in order to evaluate compliance with pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 C.F.R. 403.6(e). This adjusted limit along with supported data shall be submitted to the control authority.
d. Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 C.F.R. part 136 and amendments thereto.
e. The control authority may allow the submission of a baseline monitoring report, which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.
f. 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 discharge to the POTW.
6. Special certification. A statement, reviewed by an authorized representative of the industrial user and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operations and maintenance (O&M) and/or additional pretreatment is required in order to meet the pretreatment standards and requirements; and
7. Compliance schedule. If additional pretreatment and/or O&M will be required to meet the pretreatment standards; the shortest schedule by which the industrial user will provide such additional pretreatment and/or O&M shall be established. The completion date in this schedule will 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 § 13.16.060
(14).
8. Signature and certification. All baseline-monitoring reports must be signed and certified in accordance with § 13.16.041
.
