(1) Routine sampling is performed by the user at a frequency of at least once per month and the routine resampling will be done and results received within the thirty (30) day period of becoming aware of the violation. (2) The city performs sampling of the user's discharge between the time when the user performed the initial sampling and the time the user receives the results of this sampling and becomes aware of the violation. (b) The supervisor may at his discretion: (1) Have the user sample his discharge and have analysis done at a mutually agreeable laboratory; (2) Sample and send to a competent commercial or private laboratory for analysis. (c) Any necessary quality assurance for pretreatment sampling and analysis shall be consistent with those of 40 CFR 136 "Guidelines for establishing test procedures for the analysis of pollutants," et seq. Sec. 34-74. - Monitoring facilities. (a) The city may require to be provided and operated at the user's own cost and expense monitoring facilities to allow inspection, sampling, and flow measurement or any combination of these based upon the significance of the waste water discharge as determined by the city. The monitoring facility should normally be located on the user's premises; however, when such location would be impractical or cause undue hardship on the user, the city may allow the construction of the facility in the public street or sidewalk area in a location that will not be obstructed by landscaping or parked vehicles. The above shall apply to both old and new users when monitoring facilities are necessary. (b) Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the city's requirements and all applicable local construction standards and specifications. There shall be ample room in or near such control manhole or facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling equipment and measuring devices shall be maintained at all times in a safe and proper operating condition at the expense of the user. (c) Plans and specifications for constructions of monitoring facilities shall conform to city standards and shall be approved by the city engineer. Rental or lease of suitable equipment on an as needed basis in lieu of permanent installation may be acceptable subject to approval by the supervisor; such approval shall not release the user from the requirement to provide sampling facilities which are accessible to the city and which are secured and protected.
