When the Director of Public Works finds that a user has violated, or continues to violate, any provision of this chapter, an industrial wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the Director of Public Works may petition a court of appropriate jurisdiction through the City's Attorney for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the industrial wastewater discharge permit, order, or other requirement imposed by this chapter on activities of the user. The Director of Public Works may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the user to conduct environmental remediation. A petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against a user.
