(I) Any waters or wastes in which the COD exceeds 600 milligrams per liter, except as provided in § 51.082;
(J) Any waters or wastes in which the IOD exceeds 5.0 milligrams per liter, except as provided in § 51.082;
(K) Any waters or wastes having a stabilized pH lower than 5.5 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works, except as provided in § 51.082;
