Notwithstanding any inconsistent provisions of this chapter, whenever
the Superintendent finds, after investigation, that any user is causing,
engaging in, or maintaining a condition or activity which, in his
judgment, present an imminent danger to the public health, safety,
or welfare, or to the environment, or is likely to result in irreparable
damage to the POTW or the environment, and it therefore appears to
be prejudicial to the public interest to delay action 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 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.
