Notwithstanding any inconsistent provisions of this chapter, whenever
the Superintendent finds that any user is causing, engaging in, or
maintaining a condition or activity which, in the judgment of the
Superintendent, presents an imminent danger to the public health,
safety, or welfare, or to the environment, or is likely to result
in severe damage to the POTW or the environment, and it therefore
appears to be prejudicial to the public interest to allow the condition
or activity to go unabated until notice and an opportunity for a hearing
can be provided, the Superintendent may, without prior hearing, order
such user by notice, in writing wherever practicable or in such other
form as practices are intended to be proscribed, to discontinue, abate,
or alleviate such condition or activity, and thereupon such person
shall immediately discontinue, abate, or alleviate such condition
or activity; or where the giving of notice is impracticable, or in
the event of a user's failure to comply immediately voluntarily
with an emergency order, the Superintendent may take all appropriate
action to abate the violating condition. As promptly as possible thereafter,
not to exceed 15 calendar days, the Superintendent shall provide the
user an opportunity to be heard, in accordance with the provisions
of this article.
