Administrative enforcement

(a) If the director determines that any industrial user is violating this chapter, any rule adopted thereunder, or any permit issued pursuant thereto, the director may have the user served by personal service, by registered or certified mail or delivery, with a written notice of violation and order. (b) Within 30 days of the receipt of this notice, or such shorter period as may be provided in the notice of violation, an explanation of the violation and plan for the satisfactory correction and prevention thereof, to include specific required actions, shall be submitted to the director. Submission of this plan in no way relieves a person for any violations occurring before or after receipt of the notice of violation. Nothing in this section shall limit the authority of the director to take any action, including emergency actions or any other enforcement action, without first issuing a notice of violation, or before the expiration of the time to respond with a plan. (c) The director is authorized to seek injunctive relief or impose administrative civil penalties, or both, for violations of any federal pretreatment standard, provision or condition in any permit, or any requirement of the ordinance.
