(A) Liquids, solids, or gases which, by reason of their nature or quantity, are or may be sufficient to cause fire or explosion, be injurious in any other way to the sanitary sewer system, or be detrimental to the operation and maintenance of the system. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the sanitary sewer system, be more than 5%, nor any single reading over 10% of the Lower Explosive Limit (L.E.L.) of the meter. Prohibited materials include, but are not limited to gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, and sulfides.
(B) Any waters 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 waste treatment process, to constitute a hazard to humans or animals, to create a public nuisance, or to create any hazard in the receiving waters of the wastewater treatment facility.
(C) Any waters or wastes having pH lower than 6.0 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment operations and/or personnel of the wastewater treatment facility without a permit to do so.
(D) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in the sanitary sewers, or other interference with the proper operation of the wastewater facilities such as, but not limited to, ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, hair and flesh, entrails, lime slurry, lime residues, paint residues, cannery waste, bulk solids, paper dishes, cups, milk containers and the like, either whole or ground by garbage grinders.
(E) Any pollutant, including oxygen demanding pollutants (BOD, COD, and the like) released at a flow rate and/or pollutant concentration which will cause interference with the wastewater treatment facility's operations.
(F) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the wastewater treatment facility, or those having a chlorine demand greater than 30 mg/l.
(G) Any plating baths or acid pickling liquor, whether neutralized or not.
(H) Heat in amounts that will inhibit biological activity in the wastewater treatment facility resulting in interference, but in no case in such quantities that the influent wastewater at the treatment facility exceeds 104°F (40°C).
