(A) Sampling facilities. When required by the city, the IU shall provide and operate at the users expense, a monitoring facility, together with necessary meters and other appurtenances to allow inspection, sampling and flow measurement of each industrial sewer discharge to the city. The monitoring facility shall be approved by the city prior to being installed. When possible the sampling site shall be located outside the building or structure, on the user's premises and be easily accessible from a public road, street, parking lot or paved area. The user shall maintain safe access to the sampling site at all times.
(1) There shall be ample room in or near the facility to allow for accurate sampling and preparation of samples for analysis. The facility, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the permit holder, as directed in the city-approved permit.
(2) All sampling facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications. The sampling facility may be revised, but the city must approve these revisions. All sampling facility plans must be submitted to and approved by the city prior to construction, regardless of whether or not the standard details are used. Construction shall be completed within 60 days of city approval or within ten days of receipt of permit by the permit holder, except as otherwise approved by the city.
(B) Operation and maintenance. Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, the owner, at his expense, shall maintain then continuously in satisfactory and effective operation.
(C) Plans review.
(1) All plans for pretreatment facilities, interceptors, etc., required pursuant to these rules shall be approved by the city prior to implementation. Approval of pretreatment facilities, interceptors, etc., by the city, does not relieve the owner of the responsibility to install and operate equipment necessary to perform the required function and to meet all permit requirements.
(2) The permit holder shall maintain records of all pretreatment facilities which reflect routine maintenance check dates, calibration, cleaning, waste removal dates, manifests of wastes removed from the site and the means of disposal of accumulated wastes.
(3) Approval by the city of plans under this section does not represent assurance that the facilities will meet a discharge permit.
(D) Control of discharge. It shall be the responsibility of the user to control the discharge into the city sewerage system or any private or side sewer which drains into the city's system so as to comply with this sub-chapter and the requirements of any applicable wastewater discharge permit issued pursuant to the provisions of this sub-chapter. Notwithstanding an permit conditions, the city may (after notification to the user) order that any discharge which may appear to present an imminent endangerment to the health and welfare of persons be immediately and effectively halted from entering the collection system.
(E) IU facility inspections. The city may inspect the facilities of any IU to determine compliance with the requirements of city rules and regulations. The user shall allow the city or its representatives to enter upon the premises of the user at all reasonable hours and without prior notification by the city, for the purposes of inspection, sampling, and records examination and copying. The city shall have the right to set upon the user's property the devices as at necessary to conduct sampling, inspection, compliance monitoring and/or metering operation:
(1) Where a user has security measures in force which require proper identification and clearance before entry into their premises, the industrial user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification personnel from the city, state, and USEPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities.
(2) The city, state, and USEPA shall have the right to set up or require installation of, on the industrial user's property, the devices as are necessary to conduct sampling, and/or metering of the user's operations.
(3) The city may require the industrial user to install monitoring equipment, as necessary. The facility's sampling and monitoring equipment shall be maintained at all times in safe and proper operating condition by the industrial user at the industrial user's expense. All devices used to measure wastewater flow and quality shall be calibrated periodically to ensure their accuracy.
(4) Any temporary or permanent obstruction to safe and easy access to the industrial facility to be inspected and/or sampled shall be promptly removed by the industrial user at the written or verbal request of the city and shall not be replaced. The costs of clearing the access shall be borne by the industrial user.
(5) Unreasonable delay in allowing city personnel access to the industrial user's premises shall be a violation of this sub-chapter.
(F) Sampling requirements. Except as otherwise expressly stated in a permit, sampling shall be performed according to this division. If an IU subject to self-monitoring and reporting requirements as set forth in their city discharge permit, monitors any pollutant more frequently than required in the discharge permit, using the procedures prescribed in 40 CFR 403.12(g)(4), the results of this monitoring shall be included in the IU's reports.
(1) SIUs shall submit to the city at least once every six months or a otherwise specified by the city, a description of the nature, concentration and flow of the pollutants required to be reported to the city. These reports shall be based on sampling and analysis performed in the period covered by the report, and performed in accordance with the techniques described in 40 CFR Part 136.
(2) The IU shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the city) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of the operations.
(3) 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, a 24-hour composite sample must be obtained through flow-proportional composite sampling techniques when feasible. The city may waive flow-proportional composite sampling for any IU that demonstrates that flow-proportional sampling is unfeasible. In the case samples may be obtained through time-proportional composite sampling techniques through a minimum of four grab samples where the user demonstrates that this would provide a representative sample of the effluent being discharged.
(4) The IU shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this division. Samples shall be taken immediately downstream from pretreatment facilities if such exists or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the IU shall measure the flows at 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 alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit and supporting data shall be submitted to the city.
(5) Where 40 CFR Part 136 does not contain sampling analytical techniques for the pollutant in question, or where the USEPA Administrator determines that the Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling at analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the city or other persons approved by the USEPA Administrator. This sampling and analysis may, upon approval by the city may be performed by the city in lieu of the industrial user.
(G) Special agreements. No statement contained in this section shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment, subject to payment therefore, buy the industrial concern.
(H) Records retention. All users subject to this sub-chapter shall retain and preserve for less than three years, all records, books, documents, memoranda, reports, correspondence and any and all summaries thereof, relating to monitoring, sampling and chemical analysis made by or in behalf of a user in connection with its discharge. All records shall be subject to review by the city. The retention period may be extended beyond three years of the request of the city. All records which pertain to matters which are the subject of an enforcement or litigation activities brought by the city pursuant hereto shall be retained and preserved by the user until all enforcement activities have concluded and all periods of limitation with respect to any and all appeals have expired.
(I) Wastewater permit renewals. SIUs may be required to apply for permit renewals within 90 days prior to the expiration date in the existing wastewater permit.
