§ 51.058  CONTROL FACILITIES; PLANS AND SPECIFICATIONS.
   Plans, specifications, and any other pertinent information relating to pretreatment or control facilities shall be submitted for approval of the city and the state and no construction of such facilities shall be commenced until approval in writing, is granted. Where such facilities are provided, they shall be maintained continuously in satisfactory and effective operating order by the owner at his expense and shall be subject to periodic inspection by the city to determine that such facilities are being operated in conformance with applicable federal, state and local laws and permits. The owner shall maintain operating records and shall submit to the city a monthly summary report of the character of the influent and effluent to show the performance of the treatment facilities and for comparison against city monitoring records.

§ 51.059  CONTROL MANHOLES; LOCATION FOR SAMPLING.
   (A)   When required by the Superintendent, the owner or any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The manhole 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.
   (B)   All measurements, tests, and analyses of the characteristics of waters and wastes to, which reference is made in this chapter shall be determined in accordance with the latest edition of “Standard Methods for the Examination of Water and Wastewater,” published by the American Public Health Association, and in conformance with “Guidelines Establishing Test Procedures for Analysis of Pollutants,” Regulation 40 CFR Part 136, published in the federal register on October 16, 1973, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a 24 hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD suspended solids analyses are obtained from 24 hour composites of all outfalls whereas pH’s are determined from periodic grab samples.)

§ 51.060  TREATMENT OF UNPOLLUTED AND INDUSTRIAL COOLING WATER.
   (A)   Unpolluted water from air conditioners, cooling, condensing systems or swimming pools, shall be discharged to a storm sewer, where it is available, or to a combined sewer approved by the city. Where a storm sewer is not available, discharge may be to a natural outlet approved by the city and by the state. Where a storm sewer combined sewer, or natural sewer is not available, such unpolluted water may be discharged to a sanitary sewer pending written approval by the city.
   (B)   Industrial cooling water, which may be polluted with insoluble oils or grease or suspended solids, shall be pretreated for removal of pollutants and the resultant clear water shall be discharged in accordance with division (A).
