(3) Heat in amounts that will inhibit biological activity in the sewage treatment plant which cause, or may cause, pass-through interference, but in no case heat in such quantities such that the temperature at the sewage treatment plant headworks exceeds one hundred four degrees Fahrenheit or forty degrees Centigrade;

(4) Any waters or wastes including oxygen demanding pollutants (BOD, etc.) and suspended solids (TSS, etc.) released in either a slug load or continuous discharge of such volume, flow rate, and/or concentration which will cause, or may cause, pass-through or interference of the sewage treatment plant;

(8) Any trucked or hauled pollutants without prior approval by the superintendent or treatment plant supervisor, except at discharge points designated by the superintendent or treatment plant supervisor;

(9) Noncontact cooling water in significant amounts, unpolluted storm water, or any other direct water inflow sources which do not require treatment or would not be afforded a significant degree of treatment by the sewage treatment plant;

(10) Any waters or wastes containing dangerous waste, as prohibited by Chapter 173-303 WAC; and
