(g) Any radioactive wastes or isotopes of such half -life of concentration as may exceed limits established by the Manager in com- pliance with applicable State or Federal regulations. (h) Any waters or wastes having a pH excess of 9.5. (i) Materials which exert or cause - (1) Unusual concentrations of inert suspended solids such as, but not limited to, Fuller earth, lime slurries, and lime residues, or of dissolved solids such as, but not limited to, sodium chloride and sodium sulfate. (2) Excessive discoloration such as, but not limited to, dyes, wastes, and vegetable tanning solutions. (3) BOD or chemical oxygen demand in excess of 300 mg /1, suspended solids in excess of 300 mg /1, chlorine demands or oxygen requirements such as to cause an unusual load on the treatment works. (4) Unusual volume of flow or concentration of wastes constituting slugs as defined herein. (j) Waters or wastes containing substances which are not amen- able to treatment or reduction by the sewage treatment processes em- ployed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirement-$ of other agencies having jurisdiction over discharge to the receiving waters. Sec. 5. If any waters or wastes are discharged or are pro- posed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in Section 4 of this Article, and which, in the judgment of the Manager, may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise creates a hazard to life or constitutes a public nuisance, the Manager may (a) reject the wastes, (b) require pretreatment to an acceptable condition for discharge to the public sewers, (c) require control over the quantities and rates of discharge, and /or (d) require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer c•irges under the provisions of Section 10 of this Article. If the Manager permits the pretreatment or equali- zation of waste flows, th.e design and installation of the plants and equipment shall be subject to the review and approval of the Manager and subject to the requirements of all applicable codes, ordinances, and laws. Sec. 6. Grease, oil, and sand interceptors shall be provided when, in the opinion of the Manager, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand, or other harmful ingredients, except that Page 8 such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Little Rock Wastewater Utility and shall be located as to be readily and easily accessible for cleaning and inspection. Sec. 7. Where preliminary treatment or flow equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense. Sec. 8. When required by the Manager, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necess- ary meters and other appurtenances in the building sewer to facili- tate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed to be in accordance with plans approved by the Manager. 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. When directed to do so by the Manager, the owner of any property discharging industrial wastes shall, at his expense, obtain a representative sample of his wastewater and have the appropriate physical, chemical, and biological tests performed on this sample by a qualified testing laboratory acceptable to the Manager. The purpose of such tests shall be to determine the con- formance of the wastewater characteristics to this Ordinance. A report shall be made in writing to the Manager by the laboratory stating the results of the tests. Sec. 9. All measurements, tests, and analyses of the char- acteristics of waters and wastes to which reference is made in this Ordinance 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 z= at the control manhole provided or upon suitable samples say4 control manhole. In the event that no special manhole f' -as %per 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 twenty -four (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 and suspended solids analyses are obtained from twenty -four (24) hour composites of all outfalls, whereas the pH's are determined from grab samples taken periodically.) Sec. 10. No statement contained in this Article 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 treat- ment subject to payment therefor by the industrial concern.
