14.16.480 Reporting requirements—Baseline monitoring report.

(A) Baseline Monitoring Report.

(1) A baseline monitoring report must be submitted by existing and new industrial users subject to categorical standards and currently discharging or scheduled to discharge to the sewer system. Existing industrial users must submit the required information in this section within one hundred eighty days after the effective date of a categorical pretreatment standard or one hundred eighty days after the final administrative decision made upon a category, determination submission, whichever is later. New source industrial users must submit the required information at least ninety days prior to commencement of discharge.

(2) The city manager or his designee may require additional information as part of the report if, in his or her opinion, insufficient information has been provided. (Ref. 40 CFR 403.12(b).)

(B) Identifying Information. The user shall submit the name and address of the facility, including the name of the operator and owners.

(D) Description of Operation. The user shall submit a brief description of the nature of the process, average rate of production (flow, volume, substances and concentrations in the waste discharge). Also submit the standard industrial classification (SIC) 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 POTW from the regulated processes.

(E) Flow Measurement. Users shall submit information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from the regulated process streams and other streams as necessary to allow use of the combined wastestream formula.

(F) Measurement of Pollutants.

(1) The industrial user shall identify the pretreatment standards applicable to each regulated process.

(2) The industrial user shall submit the results of sampling and analysis from each regulated process to the city. The daily maximum and average concentration shall be reported. The sample shall be representative of daily operations.

(3) The proper and approved method of sampling (grab, flow-proportional composite, or time-proportional composite) will be utilized to obtain representative results.

(4) A minimum of one representative sample will be taken to comply with the requirements of this section.

(5) Samples should be taken immediately downstream from pretreatment facilities, if such exist, or immediately downstream from the regulated process if no pretreatment exists. All flows and concentrations must be measured to allow use of combined wastestream formula.

(6) Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto. Where Part 136 procedures do not include sampling or analytical techniques or where Part 136 methods are deemed (by EPA administrator) to be inappropriate, sampling and analysis shall occur according to procedures approved by EPA.

(7) The baseline monitoring report shall indicate the time, date and place of sampling and methods of analysis, and shall clarify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.

(8) A baseline monitoring report containing historical data may only be used upon approval by the city. (Ref. 40 CFR 403.12(b)(5).)

(G) Certification. A statement reviewed by an authorized representative of the industrial user and certified to be 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 industrial user to meet the pretreatment standards and requirements.

(H) Compliance Schedule. If additional pretreatment and/or O and 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 and M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard.
