(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 code and any applicable State or Federal pretreatment standard or requirements.
(b) Such records shall be made available upon request by the City. All such records relating to compliance with pretreatment standards shall be made available to officials of the U.S. Environmental Protection Agency (U.S. EPA) upon demand.
(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. Each discharger shall provide and operate at the discharger's own expense a monitoring facility to allow inspection, sampling and flow measurement of each sewer discharge to the City. Each monitoring facility shall be situated on the discharger's premises, except where such a location would be impractical or cause undue hardship on the discharger, the City may concur with the facility being constructed in the public street or sidewalk areas providing that the facility is located so that it will not be obstructed by landscaping or parked vehicles.
(1) There shall be ample room in, or near, such sampling facility to allow 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 discharge.
(2) All monitoring facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications. Construction shall be completed within 120 days of receipt of permit by discharger.
(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 City requirements and all applicable construction standards and specifications.
(g) Compliance determinations with respect to the prohibitions and limitations contained in this chapter may be made on the basis of either instantaneous grab samples or composite samples of wastewater. Composite samples may be taken over a 24-hour period or over a longer or shorter time span as determined necessary by the City in order to meet the needs of specific circumstances.
(h) Laboratory analysis of industrial wastewater samples shall be performed in accordance with the current edition of "Standards Methods", "Method for Chemical Analysis of Water and Waste" published by the U.S. EPA or the "Annual Book of Standards, Part 23, Water, Atmospheric Analysis" published by the American Society for Testing and Materials. Analysis of those pollutants not covered by these publications shall be performed in accordance with procedures established by the Ohio Environmental Protection Agency (Ohio EPA). In addition, all measurements, tests and analysis of the characteristics of wastewater shall also be made in conformance with the most current Federal Register (40 CFR Part 136) entitled "Guidelines for Establishing Test Procedures for the Analysis of Pollutants".
(i) Sampling of industrial wastewater for the purpose of compliance determination with respect to the prohibitions and limitations contained in this chapter will be done at such intervals as designated by the City. All records of sampling and similar information shall be kept for a period of at least three years.
(j) Duly authorized employees 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 provision of this chapter.
(k) Duly authorized employees of the City are authorized to obtain information concerning industrial processes which have a direct bearing on the kind of source of discharge to the wastewater collection system. The industry may withhold information considered confidential provided the industry establishes that revealing such information to the public might result in an advantage to competitors.
(1) While performing necessary work for private properties referred to in subsection (j) hereof, the City or duly authorized employees of the City shall observe all safety rules applicable to the premises. (Ord. 3261. Passed 12-17-13.)
