937.04  WASTEWATER MONITORING AND INSPECTION.
   (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)    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.
   (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)    Compliance determinations with respect to the prohibitions and limitations stated in Section 937.02 may be made on the basis of either instantaneous grab samples or composite samples of wastewater. Composite samples may be taken over a twenty-four 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 "Standard Methods", "Methods 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 stall be performed in accordance with procedures established by the Ohio Environmental Protection Agency (Ohio EPA). In addition, all measurement, tests and analysis of the characteristics of wastewater shall also be made in conformance with the October 16, 1975 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 stated in Section 937.02, will be done at such intervals as designated by the City.
 
   (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 provisions of this chapter.
 
   (k)    Duly authorized City employees are authorized to obtain information concerning industrial processes which have a direct bearing on the kind and source of discharge to the wastewater collection system. The industry may withhold information considered confidential provided that the industry establishes that revealing such information to the public might result in an advantage to competitors.
   (l)   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.
