(h) 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 "Standard Methods", as defined in Section 911.03(83), and in accordance with 40 CFR 136 entitled "Guidelines Establishing Test Procedures for Analysis of Pollutants," and shall be determined at the control manhole provided or upon suitable samples taken at such 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 analysis involved will determine whether a twenty-four 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 and TSS analyses are obtained from twenty-four hour composites of all outfalls, whereas pHs are determined from periodic grab samples. Within ninety days following the date for final compliance with applicable categorical pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the treatment facility, any industrial user subject to pretreatment standards and requirements shall submit to the City a report contaimng the information described in 40 CFR 403.1 (b)(4) -(6). (i) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor by the industrial concern in proportion to cost and consistent with the user charge system in Chapter 915. No special agreement shall be in violation of any federal or state standards. (j) No person shall cause the discharge of slugs of water or wastes. Each person producing a discharge into the public sewers in excess of 100,000 gallons in any one day, shall construct and maintain at his own expense, a suitable storage and flow- control facility to insure equalization of discharge over a twenty-four hour period. This facility shall have a capacity of at least fifty percent (50%) of the total normal volume of a twenty-four hour production period, and the outlet to the sewer shall be equipped with a rate-discharge controller or other approved device, the regulation of which shall be directed by the Service Director.

(b) Stormwater, surface drainage, subsurface drainage, groundwater, roof runoff, cooling water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the City Engineer.
