B. Whenever the director finds that a discharge of wastewater has been taking place in violation of any prohibition or limitations prescribed in this chapter or any of the county, state or federal effluent limitations, he shall serve a written notice upon such person. This notice will require the submission, for his approval, of a detailed time schedule of specific action which the user is required to take in order to prevent or correct such violation. Any failure to comply with such an approved time schedule or sampling and analysis, shall likewise be deemed a violation of this chapter.

C. If a violation is not corrected by timely compliance, the director may order any user to show cause why service should not be terminated.

D. It is declared to be a policy of the county that any user of wastewater treatment facilities operated by the county who violates any provision of this ordinance may have, upon due process, service disconnected from the sewer system.

E. If a user violates the discharge prohibitions of this chapter, and does not comply with subsection B of this section or an order pursuant to subsection C of this section, then a notice of termination shall be forwarded by registered mail (return receipt requested), certified mail or personal service to the owner(s) of record of the property.

F. The director shall approve reconnection to the sewer system operated by the county upon proof of the elimination of the non-complying discharge. Reinstatement of sewer service shall be in accordance with guidelines established by the director.

G. Any user who is found to have violated an order of the director or who willfully or negligently fails to comply with any provisions of this chapter or the orders, rules, or regulations hereunder, shall be fined not more than six thousand dollars for each offense (California Government Code, Section 54740). Each day on which a violation may occur or continue shall be deemed a separate and distinct offense. The county may petition the Superior Court to impose, assess, and recover a fine or to issue a preliminary or permanent injunction, or a combination thereof, as may be appropriate in restraining the continuance of such violation.

H. All costs, including overhead incurred for labor, sampling, laboratory analysis, and equipment, as a result of a user failing to comply with any provision of this chapter, shall be reimbursed to the county by that user.
