Such measurements, test, and analysis shall be made at the users’ expense. If made by the city an appropriate charge may be assessed to the user at the option of the city.
(B) The owner of any property serviced by a building sewer carrying industrial wastes or other non- residential wastewater may be required by the city to install a suitable structure together with such necessary meters and other appurtenances in the building to facilitate observation, sampling, and measurement of the wastes. Such structures, when required, shall be accessible and safely located and hall be constructed in accordance with plans approved by the city. The structures shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times. Agents of the city, the state water pollution control agencies, and the US Environmental Protection Agency shall be permitted to enter all properties for purposes of inspection, observation, measurement, sampling and testing.
(C) The strength of wastewaters shall be determined; for periodic establishment of charges provided for in §§ 51.075 through 51.087, from samples taken at the aforementioned structure at any period of time and of such duration and in such manner as the city may elect, or, at any place mutually agreed upon between the user and the city. Appropriate charges for sampling and analysis may be assessed to the user at the option of the city. The results of routine sampling and analysis by the user may also be used, for determination of charges after verification by the city.
(D) All measurements, tests, and analysis of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with latest edition of “Standard Methods” except for applications for NPDES Permits and reports thereof which shall be conducted in accordance with rules and regulations adopted by the USEPA, published in the federal register October 16,1973 (40 CFR Part 136) and any subsequent revisions subject to approval by the city.
