pH not to exceed 12 in keeping with its odor abatement efforts. <br />(17) Materials which exert or cause: <br />a. Unusual concentrations of inert S.S. (such as, but not limited to, Fullers <br />earth, lime slurries and lime residues) or of dissolved solids (such as, but not <br />limited to, sodium chloride and sodium sulfate). <br />b. Excessive discoloration (such as, but not limited to, dye wastes and <br />vegetable tanning solutions). <br />c. Unusual S.S., CBOD, BOD, ammonia-nitrogen, phosphorus, or chlorine <br />requirements in such quantities as to constitute a significant load on the sewage <br />treatment works. <br />d. Unusual volume of flow or concentration of wastes constituting "slugs," as <br />defined herein. <br />(18) Waters or wastes containing substances which are not amenable to treatment or <br />reduction by the sewage treatment processes employed, or are amenable to treatment only to <br />such degree that the sewage treatment plant effluent will be compromised. <br />(19) It shall be unlawful for any person to place, deposit, permit to be deposited, or <br />discharged in any manner whatsoever, any substance into a sewer at a point different than <br />the proposed sewer connection to the sanitary sewer system. <br />(c) If any waters or wastes are discharged, or are proposed to be discharged, to the public <br />sewers, which waters contain the substances or possess the characteristics enumerated in this <br />article, and which in the judgment of the Board may have a deleterious effect upon the sewage <br />works, processes, equipment or receiving waters, or otherwise create a hazard to life or <br />constitute a public nuisance, the Board may: <br />(1) Require new industries or industries with significant increase in discharges to submit <br />information on waste water characteristics and obtain prior approval for discharges. For <br />purposes of this requirement, flow increases of twenty (20) percent or greater, or the <br />discharge of any previously unreported pollutants shall be deemed significant. <br />(2) Reject the wastes in whole or in part for any reason deemed appropriate by the City. <br />(3) Require pretreatment of such wastes to within the limits of normal domestic sewage <br />as defined. <br />(4) Require control of flow equalization of such wastes so as to avoid any "slug" loads <br />4 <br />
