(2)

Having a pH less then 5.0 or greater than 12.0;

(3)

Containing those pesticides and other toxic pollutants in toxic amounts, determined by the administrator of the Environmental Protection Agency in accordance with the federal Act, such other federal or State acts as may be applicable, and as further designated from time to time by the Director; including the following substances or materials containing these substances: aldrin, dieldrin, benzidine, cadmium, cyanide, DDD, DDE, DDT, endrin, mercury, polychlorinated biphenyls (PCB's) toxaphene;

Any wastewater causing the treatment plant effluent to show a lethal concentration of fifty percent as determined by a toxicity test of ninety-six (96) hours or less, using a percentage of the discharge and aquatic test species chosen by the Director;

(10)

In violation of any applicable, federal categorical pretreatment standards, State standards or other local regulations covering wastewater disposal.

When the Director determines that a user(s) is discharging to the POTW any of the above enumerated substances in any amount which will interfere with the operation of the POTW, the Director shall: (1) Advise the user(s) of the impact of the discharge on the POTW; and (2) Take such actions as deemed necessary to correct the interference with the POTW.
