(A) No person shall discharge or cause to be discharged the following described substance, materials, waters, or wastes if it appears likely in the opinion of the AHJ that such wastes can harm either the septage, sewage, or leachate treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming an opinion as to the acceptability of these wastes, the AHJ will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the facility, materials of construction of the facility, nature of the treatment process, capacity of the treatment plants, degree of treatability of wastes in the sewage treatment plants, mid other pertinent factors.
(B) The substances are:
(1) Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 50 mg/l or containing substances which may solidify or become viscous at temperatures between 32° and 100°F (0° and 38°C);
(2) Any garbage that has not been properly shredded. Properly shredded means that no solids shall have a maximum dimension of more than two inches;
(3) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not;
(4) Any waters or wastes containing phenols or other taste- or odor-producing substances which are present after treatment of the composite waste in concentrations exceeding those limits as may be established by the AHJ;
(5) Materials which exert or cause:
(a) Unusual concentrations of inert suspended solids (such as but not limited to fullers 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); or
(c) BOD or chemical oxygen demand in excess of 7,000 mg/l, or chlorine requirements in such quantities as to constitute a significant load on the facility.
(6) Suspended solids in excess of 15,000 mg/l or dissolved solids in excess of 25,000 mg/l;
(7) Any waters or wastes or discharges from rain leaders, outside alleyways, foundation drains, sump pumps, or any other stormwater connections;
(8) Any waters or wastes containing concentrations of nutrients, such as P (phosphorus) and TICN (total Kjeldahl nitrogen) including other nutrients, which in the opinion of the Operator are detrimental to the POTW or may alone or in combinations affect the safe or continued operation of the POTW; and
(9) Any other substance deemed harmful to the facility by the Director or Operator.
