STORM SEWER PROTECTION

§ 53.15 MAINTENANCE.

   Any person in control of any part of a storm sewer system, including any stormwater management facility or any surface or subsurface stormwater conveyance system, shall maintain those components in good and workable condition. The owner shall promptly repair and restore the systems or components when conditions warrant.

(2004 Code, § 105-5) (Ord. 04-03, passed 4-1-2004)

§ 53.16 SUSPENSIONS; TERMINATIONS.

   (A)   The county may, without prior notice, suspend any approved discharge access to a CS4 to a person, when suspension is necessary to stop an actual or threatened discharge which presents or may present imminent and substantial danger to the environment, to public health or welfare, or to any system, watercourse, or designated sensitive resource. If a person fails to comply with a suspension order, the county may take steps to prevent or minimize damage to any storm sewer system, watercourse, or sensitive resource or to minimize an identified danger or hazard to the general health and welfare.

   (B)   A person discharging to a CS4 or watercourse in violation of this chapter may have the system access terminated if such termination would abate, reduce, or eliminate an illicit discharge. The county shall notify a violator in writing of the proposed termination of system access. The violator may petition the county for reconsideration. Reinstatement of a discharge, connection, or access which has been terminated pursuant to this section without the county approval constitutes a violation of this chapter.

(2004 Code, § 105-6) (Ord. 04-03, passed 4-1-2004)

   A person subject to an industrial or construction activity NPDES stormwater discharge permit shall comply with all provisions of the permit. Proof of compliance with the permit shall be submitted in a form acceptable to the county prior to allowing any discharge to the CS4.

§ 53.18 INSPECTIONS.

   This section applies to all facilities that have stormwater discharges, including construction activity or any other discharge to any CS4.

   (A)   The county may, upon notification, enter and inspect the source of any discharge, including those under an individual or general NPDES permit, that are subject to this chapter when necessary to determine compliance. Failure to cooperate with an inspection constitutes a violation of this chapter.

   (B)   To determine compliance, the county may inspect, sample, examine, and investigate the source of any discharge to a CS4. In support of any investigation, the county may review and copy any records maintained pursuant to the conditions of any discharge permit or this chapter.

   (C)   The county may require the discharger to install monitoring equipment if the nature of the discharge warrants. The facility’s sampling and monitoring equipment shall be maintained in a safe and proper operating condition by the discharger at its own expense. All devices used to measure stormwater flow and quality shall be calibrated to ensure accuracy.
