(b) Solid or viscous pollutants in any amount that is likely to cause obstruction to the flow in the POTW or result in interference with the proper operation of the POTW;

(c) Any pollutant, including oxygen-demanding pollutants, released in a discharge at a flow rate or pollutant concentration or quantity that is likely to:

(5) Cause pass through;

(d) Any waste that contains a concentration or quantity of any pollutant such that the introduction of the waste to a POTW is likely to cause a treatment process upset and subsequent loss of treatment ability;

(e) Any waste that contains heat in an amount that is likely to inhibit biological activity in a POTW resulting in an interference, and in no case heat in such quantities that the temperature of the influent at the WWTP headworks exceeds 40°C, equivalent to 104°F;

(f) Pollutants that create a fire or explosion hazard in the POTW, including but not limited to waste streams with a closed cup flashpoint of less than 140°F, equivalent to 60°C, using the test methods specified in 40 CFR Part 261.21;

(g) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in an amount that is likely to cause interference or pass through;

(i) Any trucked or hauled pollutants, except at discharge points designated by the POTW;

(j) Any medical/infectious waste or radiological waste designated by the municipality as having a reasonable potential for adversely affecting the POTW's operation or performance or for violating any pretreatment standard or requirement;

(k) Any wastewater that is likely to cause the POTW's effluent or sludge to fail a toxicity test;

(l) Any hazardous waste listed or designated by the department under Env-Hw 400; and
