Ordinance No. 92 - 133 Page 9 1. Control manholes or access facilities shall be located and built in a manner a.cceptable to the Service Director. If ineasuring devices are to be permanently installed, they shall be of a type acceptable to the Service Director. 2. Control manholes, access facilities and related equipment shall be installed by the person discharging the waste, at his expense, and shall be ma.intained by him so as to be in safe condition, accessible and in proper operating condition at all times. Plans for the installation of the control manholes or access facilities and related equipment shall be approved by the City Engineer prior to the beginning of construction. (h) All measurement 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 upan suitable samples taken at such control manhole. In the event that no special manhole ha.s been required, the control manhole shall be considered to be the nearest downstream manhole in the pu.blic 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 hazard 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, lut not always, BOD and TSS analyses are obtained frcn twenty-four composites of all outfalls, where pHs are determined from periodic grab samples. Within 90 days following the date for final compliance with applicable categorical pretreatment standards, or in the ca.se of a New Source following commencement of the introduction of wastewater into the treatment facility, any industrial user subject to pretreatment standards and requirements sha.ll submit to the City a report containing 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 ma.y be accepted by the City for treatment, subject to payment therefore by the industrial concern in proportion to cost and consistent with the user cha.rge system in Chapter 915. No special agreement shall be in violation of any Federal or State standards. (j) No person shall ca.use the discharge of slugs of water or wastes. Each person producing a discha.rge into the public sewers in excess of 100,000 gallons in any one day, shall construct and maintain, at his expense, a suitable storage and flow-control facility to insure equa.lization of discharge over a twenty-four hour period. Zhis facility shall ha.ve a capacity of at least fifty percent (500) of the total normal volume of a twenty-four production period, and the autlet 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."
