(A) The Public Works Superintendent may immediately suspend a industrial user’s discharge, after informal notice to the industrial user, whenever such suspension is necessary to stop an actual or threatened discharge, which reasonably appears to present, or cause an imminent or substantial endangerment to the health or welfare of persons. The Public Works Superintendent may also immediately suspend an industrial user’s discharge, after notice and opportunity to respond, that threatens to interfere with the operation of the POTW, or which presents or may present an endangerment to the environment.
(1) Any industrial user notified of a suspension of its discharge shall immediately stop or eliminate its contribution. In the event of an industrial user’s failure to immediately comply voluntarily with the suspension order, the Public Works Superintendent may take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The Public Works Superintendent may allow the industrial user to recommence its discharge when the industrial user has demonstrated to the satisfaction of the Public Works Superintendent that the period of endangerment has passed, unless the termination proceedings in § 55.086 are initiated against the industrial user.
(2) An industrial user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the Public Works Superintendent prior to the date of any show cause or termination hearing under §§ 55.081 or 55.086.
(B) Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this section.
