(6) Any waters or wastes containing phenols or other taste- or odor-producing substances, in concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters;
(7) Any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations;
(8) Any waters or wastes having a pH in excess of 10.5;
(9) Materials which exert or cause:
(a) Unusual concentrations of inert suspended solids (such as, but not limited to, fuller’s earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate);
(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(c) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; or
(d) Unusual volume of flow or concentration of wastes constituting slugs, as defined herein.
(10) Water or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such a degree that the sewage treatment plant effluent cannot meet the requirements of the current National Pollutant Discharge Elimination System permit (NPDES) or other agencies having jurisdiction over discharge to the receiving waters.
(1983 Code, § 21-68)

(2) Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant;
(3) Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works;
(4) Solid or viscous substances in quantities or of a size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works, such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups, milk containers, and the like, either whole or ground by garbage grinders;
(5) Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg; or
(6) Any waste containing detectable levels of cyanide at any time except as permitted with the approval of the State Environmental Protection Agency as specified in the Water Pollution Regulations of this state, Rule 703.
