(B) Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0, unless the works is specifically designed to accommodate such discharges;
(C) Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interference;
(D) Any pollutant, including oxygen demanding pollutants (BOD and the like) released in a discharge at a flow rate and/or pollutant concentration which will cause Interference with the POTW;
(E) Heat in amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW treatment plant exceeds 40°C (104°F) unless the approval authority, upon request of the POTW, approves alternate temperature limits;
(F) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through;
(G) Pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems;

(J) Any hot, suffocating, corrosive, inflammable or explosive liquids, gases, acids, vaporous substances, or toxic material or liquid that can endanger life, limb, public property or constitute a nuisance;
(K) Any liquid or vapor having a temperature higher than 150°F;
(L) Any waters containing suspended solids of such character and quantity that unusual provisions, attention, or expense is required to handle the materials at the sewage treatment plant;
(M) 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; or
