(A) Baseline report (for categorical dischargers only).
(1) Industrial users subject to national categorical pretreatment standards shall submit baseline reports to the city in a form prescribed and furnished by the city.
(2) Within 180 days after the effective date of a national categorical pretreatment standard, or 180 days after a final administrative decision has been made upon a categorical determination submission in accordance with 40 C.F.R. § 403.6(a)(4), whichever is later, industrial users which are existing sources subject to such National Categorical Pretreatment Standards and currently discharging to the POTW shall submit a properly completed baseline report.
(3) New sources, when subject to a national categorical pretreatment standard, shall submit a baseline report no later than 180 days after discharging to the city.
(4) In support of the baseline report, the industrial user shall submit, in units and terms specified in the application, the following information:
(a) Name and address of the facility including the name of the operator and owners;
(b) List of any environmental control permits held by or for the facility;
(c) Brief description of the nature, average rate of production, and standard industrial classification of the operation(s) carried out by such user. This description shall include a schematic process diagram indicating points of discharge to the POTW from the regulated processes; and
(d) Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:
1. Regulated process streams; and
2. Other streams as necessary to allow use of the combined waste stream formula of 40 C.F.R. § 403.6(e).
(e) The industrial user shall identify the national categorical pretreatment standards applicable to each regulated process, and shall:
1. 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;
2. Where feasible, obtain samples through the flow-proportional composite sampling techniques specified in the applicable national categorical pretreatment standard. Where composite sampling is not feasible, a grab sample is acceptable;
3. Sample based on the flow of the sampled stream, as follows (composite samples are required where feasible):
a. Where the flow of the stream being sampled is less than or equal to 950,000 liters/day (approximately 250,000 gpd), the industrial user shall take a minimum of three samples within a two-week period; and
b. Where the flow of the stream being sampled is greater than 950,000 liters/day (approximately 250,000 gpd) the industrial user shall take a minimum of six samples within a two-week period.
4. Take the samples 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, in order to evaluate compliance with the national categorical pretreatment standards, the industrial user shall measure the flows and concentrations necessary to allow use of the combined waste stream formula of 40 C.F.R. § 403.6(e). Where an alternate concentration has been calculated in accordance with 40 C.F.R. § 403.6(e), this adjusted limit along with supporting data shall be submitted to the city;
5. Perform sampling and analysis in accordance with Standard Methods;
6. Submit, only with city authorization, 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
7. Provide for each report, the time, date, and place of sampling and methods of analysis and certification that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.
(f) The industrial user shall provide a statement, reviewed by an authorized representative of the industrial user and certified by a qualified professional, indicating whether national categorical pretreatment standards are being met on a consistent basis and, if not, whether additional operation and maintenance measures (O&M) or additional pretreatment is required for the industrial user to meet the national categorical pretreatment standards;
(g) If additional pretreatment or O&M will be required to meet the national categorical pretreatment standards, the industrial user will provide the shortest schedule which will provide such additional pretreatment or O&M. The completion date in this schedule shall not be later than the compliance date established for the applicable national categorical pretreatment standard.
1. Where the industrial user’s national categorical pretreatment standard has been modified by a removal allowance (40 C.F.R. § 403.7) or the combined waste stream formula (40 C.F.R. § 403.6(e)), or net/gross calculations (40 C.F.R. § 403.15), at the time the industrial user submits a baseline report the information required in divisions (A)(4)(f) and (A)(4)(g) of this section shall pertain to the modified limits.
2. If the national categorical pretreatment standard for the industrial user is modified after the baseline report is submitted, the industrial user shall make any necessary amendments to information provided as a response to divisions (A)(4)(f) and (A)(4)(g) of this section and submit them to the city within 60 days after the modified limit is approved.
(h) The following conditions shall apply to any schedule submitted in response to division (A)(4)(g) of this section:
1. The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the user to meet the applicable national categorical pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, and the like);
2. No increment referred to in division (A)(4)(h)1. above shall exceed nine months; and
3. Not later than 14 days following each date in the schedule and the final date for compliance, the user shall submit a progress report to the city including, at a minimum, whether or not it has complied with the increment of progress to be met on such date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the industrial user to return the construction to the schedule established. In no event shall more than nine months elapse between such progress reports to the POTW.
(B) Compliance date report. Within 90 days following the date for final compliance with applicable pretreatment standards, or in the case of a new source, within 45 days following commencement of the introduction of wastewater into the POTW, any industrial user subject to pretreatment standards shall submit to the city a report, on forms provided by the city, indicating the nature and concentration of all pollutants in the discharge from the regulated process which are limited by pretreatment standards and the average and maximum daily flow for these process units in the user’s facility which are limited by such pretreatment standards. The report shall state whether the applicable pretreatment standards are being met on a consistent basis and, if not, what additional user operation and maintenance or pretreatment techniques or installations are necessary to bring the user into compliance with the applicable pretreatment standards. This statement shall be signed by an authorized representative of the industrial user and certified to by a qualified professional.
(C) Periodic compliance reports for all significant industrial users.
(1) All significant industrial users subject to an applicable pretreatment standard, after the compliance date of such applicable pretreatment standard or, in the case of a new source, after discharge of wastewater to the POTW begins, shall submit to the POTW during the months of June and December for the preceding two calendar quarters, a certified report indicating the nature and concentration of pollutants in the effluent which are limited by such applicable pretreatment standards. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period.
(2) At the discretion of the city, the wastewater discharge permittee shall sample, analyze, and report to the city pollutants set forth in its wastewater discharge permit.
(3) At the discretion of the city and in consideration of such factors as a local high or low flow rate, holidays, or budget cycles, the city may agree to alter the months during which the above reports are submitted.
(4) All measurements, tests, and analyses of the characteristics of wastewater to which reference is made in this chapter shall be determined in accordance with Standard Methods.
