(A) Industrial wastewater discharge analysis; required; reports.
(1) The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of waters and wastes to illustrate compliance with this subchapter and any special conditions for discharge established by the city or regulatory agencies having jurisdiction over the discharge.
(2) The number, type, and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the city, but no less than once per year the industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state, and local standards are being met.
(3) The owner shall report the results of measurements and laboratory analyses to the city at such times and in such manner as prescribed by the city.
(4) The owner shall bear the expense of all measurements, analyses, and reporting required by the city.

(B) Determination; sample taken; sampling methods.
(1) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this subchapter 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 shall be determined at the control manhole provided, or upon suitable samples taken at said control manhole.
(2) 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.
(3) 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.
(4) The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pH is determined from periodic grab samples.

(C) Special agreement authorized. No statement contained in §§ 50.074(B) through (E), 50.075 through 50.078, and divisions (A) and (B) above shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an individual waste of unusual strength or character may be accepted by the city for treatment, subject to payment therefor, in accordance with §§ 50.081 through 50.085 hereof, by the industrial concern, provided such payments are in accordance with federal and state guidelines for user charge system and industrial cost recovery system.
