§ 53.085 TOXIC SUBSTANCES PROHIBITED OR ACCEPTED CONDITIONALLY.

   (A)   The following is a partial list of toxic substances and pathogenic bacteria, the admission of which into the public sewer system is hereby prohibited unless their concentration:

      (1)   Is reduced by treatment at the source to a point that will meet the general purposes of these rules and regulations (§§ 53.083 through 53.088) or come within the acceptable standards formally established by the borough through issuance of a permit described under § 53.086; and

      (2)   Will not adversely affect sludge handling or any other biochemical, biological or other sewage treatment process:

         (a)   Alcohols;

         (b)   Antibiotics;

         (c)   Arsenic and arsenicals;

         (d)   Bromine, iodine, chlorine;

         (e)   Copper or copper salts;

         (f)   Creosols or creosotes;

         (g)   Fluorine;

         (h)   Formaldehydes;

         (i)   Mercury and mercurials;

         (j)   Phenols and their derivatives;

         (k)   Silver and silver compounds;

         (l)   Sulfonamides, toxic dyes (organic or mineral);

         (m)   Zinc compounds;

         (n)   All strong oxidizing agents, such as chromates, dichromates, permanganates, peroxides and the like;

         (o)   Chemical compounds producing toxic, inflammable or explosive gases, either upon acidification, alkalization, oxidation or reduction;

         (p)   Strong reducing agents such as nitrites, sulphides, sulphites and thiosulphates and the like;

         (q)   Wastes from industrial processes or hospital procedures containing viable pathogenic organisms;

         (r)   Cyanide; and

         (s)   Heavy metals, such as chromium, nickel, iron, zinc, tin, copper, cadmium, lead and the like.

   (B)   The concentration in sewage of any toxic substances shall not exceed those concentrations judged by the borough to be toxic to biological sewage treatment processes or to the biota of the receiving stream, and shall not exceed those previously approved and formally permitted by the borough before they are discharged to the sewer.

   (C)   When the volume of a single toxic industrial waste discharge, or the combined toxic industrial waste discharge of a group of industries within a single contributary area, is such as to raise a question of the ultimate concentration of toxic substances entering a treatment plant or a receiving stream, the borough may impose separate or special concentration limits upon the contributors. Conversely, where a toxic industrial waste discharge may be expected to be highly diluted or rendered innocuous before reaching a treatment plant or a receiving stream, the borough may conditionally permit such discharge.
