user subject to categorical pretreatment standards is a nonsignificant
categorical industrial user rather than a significant industrial user
on a finding that the industrial user never discharges more than 100

Upon a finding that a user meeting the criteria
in Subsection A(2) of this definition has no reasonable potential
for adversely 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.

(3)
Any other violation of a pretreatment standard or requirement as defined by §
253-35A (daily maximum or longer-term average, instantaneous limit, or narrative standard) that the Township determines has caused, either alone or in combination with other discharges, an interference or pass-through, including endangering the health of POTW personnel or the general public.

imminent endangerment to the health of the Township personnel, the
environment or the general public; or has resulted in exercising any
emergency authority to halt or prevent such a discharge.
