affecting the POTW's operation or for violating any pretreatment standard
or requirement, the Township may at any time, on its own initiative
or in response to a petition received from an Industrial User, and
in accordance with procedures in 40 CFR 403.8(f)(6), determine that
such User should not be considered a Significant Industrial User.
