(2) 
Cause and/or contribute to a back-up or sanitary sewer overflow onto public or private property or into the MS4; or
(3) 
Pose a threat to public health or the environment.
(b) 
The city may require a non-domestic user to accelerate the pumping of a treatment device from the prescribed pumping frequency if the user:
