In no case shall pollutants be discharged with a closed cup flashpoint less than 140°F (60°C), or pollutants which cause an exceedance of 10% of the lower explosive limit (LEL) at any point within the wastewater treatment plant for any single reading or more than 5% for any two consecutive readings.
(C) Solid or viscous pollutants, petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass-through or that will cause obstruction to the flow in sewers or other interference or damage with the system or treatment plant.

(E) Any waters with a pH less than five standard units (S.U.) or greater than 9 S.U. except as provided in § 51.028.
(F) Any waters with a temperature greater than 150°F (66°C) or heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no event heat in such quantities that the temperature at the headworks of the POTW treatment plant exceed 104°F (40°C).
(G) Any water or waste which may contain more than 50 parts per million by weight of fat, oil or grease.
(H) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(I) Any garbage that has not been properly shredded.
(J) Any ashes, cinders, sand, mud, straw, shavings, metal, glass rags, feathers, tar, plastics, wood, paunch, manure, grits such as brick, cement, onyx, carbide or any other solid or viscous substance capable of causing obstruction to the flowing sewers or other interference with the proper operations of the sewer works.

(O) Any water or waste that could cause a violation of any categorical standard or pretreatment requirement.
(P) Any water or waste that is transported from the point of generation to the POTW by any septic tank pumper, chemical waste hauler or similarly transported unless the transporter has first:
(1) Disclosed to the Director the origin, nature, concentration and volume of all pollutants to be discharged; and
(2) Obtained the written consent of the Director to discharge.
(Q) Any water or waste which could cause interference or pass-through with POTW operations.
(R) Any discharge that exhibits a characteristic of a hazardous waste, or contains a substance that is listed as a hazardous waste pursuant to either Arizona Administrative Code R 18-8-261 or Title 40 C.F.R. part 261, whichever is applicable, whether or not the discharge is otherwise subject to hazardous regulations. This provision does not apply to domestic wastewater or to discharges of hazardous wastes that are authorized by the Director.
(S) Any water or waste exceeding the limits for the effluent limitations that are expressed in the total form as regulated by State Department of Environmental Quality for the permitted facility.
