(a) All industrial users who discharge or propose to discharge wastewaters to the wastewater treatment system shall maintain such records of production and related factors, effluent flows, and pollutant amounts and concentrations of such pollutants that are necessary to demonstrate compliance with the requirements of this chapter and any applicable State or federal pretreatment standards or requirements.
(b) The Discharger shall allow the Service Director or his representative to enter upon the premises of the Discharger during any reasonable hour for the purposes of inspection, sampling, and records examination and copying to determine compliance with the requirements of this chapter. Where the industry has security measures in force which require proper identification and clearance before entry, the discharger shall make necessary arrangements so that the Service Director or his representative will be permitted entry without delay. The City shall have the right to set up on the discharger's property necessary devices to conduct sampling, inspection, compliance monitoring, metering operations, or all of these.
(c) If so ordered by the City, the owner or operator of any premises or facility discharging industrial wastes into the system shall install at his own cost and expense suitable monitoring equipment to facilitate the accurate observation, sampling, and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times.
(d) The monitoring equipment shall be located and maintained on the industrial user's premises outside of the building. When such a location would be impractical or cause undue hardship on the user, the City may allow such facility to be constructed in the public right of way, with the approval of the public agency having jurisdiction of such right of way, and located so that it will not be obstructed by public utilities, landscaping, or parked vehicles.
(e) When more than one user can discharge into a common sewer, the City may require installation of separate monitoring equipment for each user. When there is a significant difference in wastewater constituents and characteristics produced by different operations of a single user, the City may require that separate monitoring facilities be installed for each discharge.
(f) Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the City requirements and all applicable construction standards and specifications.
(g) Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on data that is representative of conditions occurring during the reporting period.
(1) Except as indicated in subsections (g)(2) and (3) below, the User must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the Director. Where time-proportional composite sampling or grab sampling is authorized by the City, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the City, as appropriate. In addition, grab samples may be required to show compliance with Instantaneous Limits.
(2) Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
(3) For sampling required in support of baseline monitoring and periodic compliance reports required in Section 925.18(b) and 925.18(g) [40 CFR 403.12(b) and (d)], a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the Director may authorize a lower minimum. For the periodic compliance reports required by City and 40 CFR 403.12(e) and 403.12(h), the Industrial User is required to collect the number of grab samples necessary to assess and assure compliance by with applicable Pretreatment Standards and Requirements.
(h) Laboratory analysis of industrial wastewater samples shall be performed in accordance with the techniques established is 40 CFR Part 136 entitled "Guidelines for Establishing Test Procedures for the Analysis of Pollutants." Analysis of those pollutants not covered by this publication shall be performed in accordance with the current edition of "Standard Methods," "Methods for Chemical Analysis of Water and Waste," published by the U.S. Environmental Protection Agency, or the "Annual Book of Standards, Part 23, Water, Atmospheric Analysis," published by the American Society for Testing and Materials. Analysis of these pollutants not covered by these publications shall be performed in accordance with procedures established by the Ohio Environmental Protection Agency. If a significant industrial user's sampling data indicates a violation of any parameters listed in the discharge period, the industrial user must notify the City within twenty-four hours of becoming aware of the violation. The significant industrial user must then repeat the sampling and analysis and submit the results to the City within thirty days.
(i) Sampling of industrial wastewater for the purpose of compliance determination with respect to the prohibition and limitations stated in Section 925.05 will be done at such intervals as designated by the City. Users subject to the reporting requirements of this ordinance shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this ordinance, any additional records of information obtained pursuant to monitoring activities undertaken by the User independent of such requirements, and documentation associated with Best Management Practices established under Section 925.18(d). Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the User or the City, or where the User has been specifically notified of a longer retention period by the Director.
(j) Industrial users are required to provide an access point in order to sample the wastewater discharge.
(k) At any reasonable time, duly authorized representatives of the City bearing proper credentials and identifications shall be permitted to enter all properties for the purposes of inspection, observation, measurement, sampling, and testing pertinent to discharge to the community system in accordance with the provisions of this chapter.
(l) Information and data furnished to the City with respect to the nature and frequency of discharge shall be available to the public or other government agency without restriction unless the discharger specifically requests and is able to demonstrate to the satisfaction of the City that the release of such information would divulge trade secrets or proprietary information. Wastewater constituents and characteristics will not be recognized as confidential information. Information accepted by the City as confidential shall be made available to governmental agencies upon request.
(m) While performing necessary work for private properties referred to above, the City or duly authorized employees of the City shall observe all rules applicable to the premises.
