The Director, after notifying the discharger by telephone or in person,
may immediately halt or prevent any discharge of pollutants to a public
sewer that reasonably appears to present an imminent endangerment
to the health or welfare of persons, or any such discharge presenting
(or which may present) an endangerment to the environment or which
threatens to interfere with the operation of the City's wastewater
works. Actions which may be taken by the Director may include, but
are not limited to, seeking injunctive relief, entry on private property
to halt such discharge, blockage of a public sewer to halt such discharge,
or demand of specific action by the discharger.
