Except as hereinafter provided, no person shall discharge or cause to be discharged to any sewerage system any of the following described substances, wastes or waters:
(A) Any liquid or vapor having a temperature higher than 150°F;
(B) Any waters or wastes containing more than 100 mg/l of fats, oils, greases or waxes;
(C) Any gasoline, benzene, naphtha, fuel oil or mineral oil or any other flammable or explosive liquid, solid or gas;
(D) Any noxious or malodorous gas or substance which, either alone or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into sewers for their maintenance and repair;
(E) Any garbage that has not been properly ground;
(F) Any ashes, cinders, sand, mud, straw, shavings, wood, metal, glass, rags, feathers, tar, plastics, paunch manure, butchers’ offal of any other solid or viscous substances capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewerage system or the WWTP;
(G) Any waters or wastes having a pH lower than six or higher than nine or having any other corrosive property capable of causing damage or posing hazards to the structure, equipment or personnel of the sewage works;
(H) Any waters or wastes containing acid metallic pickling wastes or concentrated plating solutions;
(I) Any toxic radioactive isotopes;
(J) Any waters or wastes that for a duration of five minutes or more have a concentration more than five times the average concentration of the BOD or the suspended solids of the customer’s sewage discharged during a 24-hour period of normal operation;
(K) Any waters or wastes containing suspended solids of such character and quantity that unusual provision, attention and expense would be required to handle such materials at the WWTP, its pumping stations or other facilities.
(L) Any waters or wastes containing toxic substances, as defined under § 307(b) and (c) of the Clean Water Act in sufficient quantity to interfere with the biological process of the sewage treatment plant or that will pass through the plant into the receiving stream in amounts exceeding the standards set by federal, interstate, state or other competent authority having jurisdiction, or will prevent the disposal of the sludge by the plant in accordance with 33 U.S.C. § 1345;
(M) Any waters or wastes containing non-compatible pollutants as defined herein;
(N) A pollutant from any source of non-domestic sewage that could pass through or cause interference with the operation and performance of the sewage works;
(O) A pollutant that could create a fire or explosion hazard in the sewage works, including waste streams from a closed cup flashpoint of less than 140°F (60°C) using the test methods in 40 C.F.R. § 261.21;
(P) A pollutant, including an oxygen demanding pollutant (such as biochemical oxygen demand) released in a discharge at a flow rate or pollutant concentration that could cause interference in the sewage system;
(Q) Heat in an amount that could:
(1) Inhibit biological activity in the sewage system and result in interference or damage to the sewage system; or
(2) Exceed 104°F (40°C) at the WWTP unless the Superintendent, upon request, approves alternate temperature limits.
(R) A trucked or hauled pollutant, except:
(1) With the permission of the Superintendent; and
(2) When introduced to the sewage system at a discharge point designated by the Superintendent (and upon paying the proper fees).
(S) Any toxic ions, compounds or substances exceeding the amounts of concentrations as set out below, or as set out in any pretreatment requirement, whichever is more stringent.
