(A) Any liquid or vapor having a temperature higher than 1400F;
(B) Any water or waste containing more than 100 ppm by weight of fats, oils or greases;
(C) Any liquids, solids or gases which, by reason of their nature or quality, may cause fire or explosion or be in any way injurious to persons, to the sewage works structures or to the operation of the works;
(D) Any noxious or malodorous gas or substance which, either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or preventing entry into sewers for their maintenance and repair;

(I) Any water or waste that contains cyanide in excess of a concentration determined by multiplying 0.2 ppm by the ration of the average flow in the receiving stream to the design flow of the sewage treatment works;
(J) Any water or waste containing suspended solids of the character and quantity that unusual attention or expense is required to handle the materials at the sewage treatment plant;
(K) Any toxic radioactive isotopes, without special permit;
(L) Any water or waste that contains fluoride in excess of a concentration determined by multiplying 1.2 ppm by the ratio of the average flow in the receiving stream to the design flow of the sewage treatment works; and
