(1) Pollutants which create fire or explosion hazard in the POTW, including, but not limited to, wastestreams with a closed-cup flashpoint of less than 140°F (60°C) using test methods specified in 40 C.F.R. § 261.21;
(2) Pollutants which will cause corrosive structural damage to the POTW or equipment, but in no case discharges with a pH lower than 5.0;
(3) Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD and the like) released in a discharge at a flow rate and/or a pollutant concentration which will cause interference with the POTW;

(6) Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin, in amounts that will cause interference or pass through;
