The purpose of this chapter is to regulate the city’s municipal separate storm sewer system (“MS4 or stormwater drainage system”) regarding the introduction of pollutants that would adversely impact surface and groundwater quality of the state of Washington in order to comply with requirements of the city’s National Pollutant Discharge Elimination System (“NPDES”) permit. The intent of this chapter is to:

(1) Prevent and control the introduction of pollutants to the stormwater drainage system by any person and/or entity within the permit boundary.

(2) Prohibit illicit connections and discharges to the stormwater drainage system and receiving waters within the permit boundary.

(3) Establish legal authority to carry out all inspection, surveillance, monitoring procedures and enforcement necessary to ensure compliance with this chapter. [Ord. 1456 § 1, 2009.]

Such records shall be filed with the county auditor in association with the deed or other transfer document and a copy provided to the enforcement officer. [Ord. 1456 § 1, 2009.]

14.20.050 Enforcement.

(1) Failure to Comply. It is unlawful for any person to violate any of the following provisions or fail to comply with any of the requirements of this chapter. Any activity or action caused or permitted to exist in violation of this chapter is a violation subject to enforcement under this chapter.

(2) Emergency Access and Reparation. In the event the violation constitutes an immediate danger to public health or safety, the enforcement officer is authorized to enter upon the subject private property, without giving prior notice, to take any and all measures necessary to abate the violation and/or restore the property. Any expense related to such remediation undertaken by the city shall be fully reimbursed by the property owner and/or person. Any relief obtained under this section shall not prevent the city from seeking further relief or applying other penalties as outlined in this chapter.

(3) Investigation. Investigation of a violation of this chapter may be initiated by any enforcement officer duly authorized by the city upon observation or report of any violation. The violation will be investigated to determine whether or not an illicit connection or illicit discharge, as previously defined, exists.

A written statement of the violation, including date, time, address, name of property owner, resident and/or name of person making illicit discharge or connection to the stormwater system and a description of the violation, will be signed under penalty of perjury and given to the person who has allegedly violated the chapter. The written notice will also contain instructions on how to appeal the notice of violation. The enforcement officer will request a signature from the person, acknowledging receipt of the written notice of violation. The written notice may also be mailed, return receipt required, to the alleged violator and deemed served three days from date of mailing. A notice of violation shall be posted on the property. In the event personal service is not made, and mail is returned without forwarding information, the posted notice is sufficient notice to proceed with enforcement actions.

(4) Violation.

(a) The first violation of this chapter resulting from conduct made unlawful by this chapter shall result in a written notice of violation describing the illegal nature of the discharge or connection. The person will be required to develop a plan within 10 days of receipt of written notice of violation to be approved by the city-designated official to eliminate the illicit discharge or illicit connection and remove the illicit discharge or illicit connection. The notice of violation will contain verbiage that informs the recipient that if the violation is not abated, a fine of up to $1,000 per day may be imposed until the violation is abated. The written notice will also contain instructions on how to appeal the notice of violation. The enforcement officer will request a signature from the person, acknowledging receipt of the written notice of violation. The written notice may also be mailed, by regular and return receipt required to the alleged violator and deemed served three days from date of mailing. Proof of this mailing and proof of posting the notice at the property will be required at any appeal.

(b) Second and subsequent violations within 12 months constitute a misdemeanor pursuant to RCW 9A.20.010(2). The penalty for second violations will increase. The first day of a violation, the fine will be up to $100.00; second day the violation continues, the fine will be up to $200.00; the third day and every subsequent day the violation continues the fine will be $300.00 up to $1,000 and 30 days in the county jail. The city may elect to prosecute under any possible violations of the Federal Clean Water Act, NPDES Phase II permit, and/or Chapter 90.48 RCW and will report second and subsequent violations to the Washington State Department of Ecology.

The enforcement officer has the right to install or require the property owner to install monitoring equipment as is reasonably necessary in the opinion of the enforcement officer to conduct appropriate monitoring and/or sampling of the facility’s stormwater discharge. The facility’s sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the property owner at his/her own expense. All devices used to measure stormwater flow and quality shall be calibrated according to industry standards to ensure their accuracy.

All data shall be collected in accordance with a sampling and analysis plan that is approved by the enforcement officer.

(c) The city may elect to implement an ordinance authorizing enforcement of this chapter by in rem actions.

(d) Hearing Request.

(i) “Hearing officer” means the official appointed by the city for administrative hearings.

(A) The hearing officer shall hear all appeals of decisions under this chapter.

(B) The hearing officer shall hear evidence presented by whomever the city designates.

(C) The hearing officer shall likewise hear evidence presented by the person appealing the decision or interpretation.

(D) In the case of an appeal of a notice of civil violation and/or order to abate issued by the enforcement officer, the burden of proof at the hearing shall rest with the city. If the decision of the enforcement officer is found to be supported by a preponderance of the evidence, the decision shall be affirmed.

(E) Formal rules of evidence need not be followed, but witnesses shall be sworn by the hearing officer and a written order issued.

(F) A person may appeal the written notice of violation entered by the hearing officer to the district court within 10 days of the hand-delivered notice or within 10 days of the postmark of the mailed notice. The request must contain a copy of the written notice, and the name, address and telephone number of the person requesting the hearing. The request must also include a brief description of the reason the person believes there is no violation. This request will be mailed to the enforcement agency, which will set the hearing date. The district court will review the matter de novo.

(G) The city is not required to pay the hearing officer if a decision on a hearing has not been rendered within 30 days of the date of the hearing.

(ii) A notification giving the time, location and date of such hearing on the questions of abatement and removal of the illicit discharge or connection will be sent to the person requesting the hearing or his/her authorized representative by certified mail with a five-day return receipt requested.

(iii) Failure of any person to file a timely appeal or failure of any person who has filed an appeal to attend the scheduled hearing shall constitute a waiver of his or her right to an appeal hearing.

(iv) Filing of an appeal shall stay the enforcement of any notice of civil violation, order to abate, collection of fine, penalties or assessments or termination of service during the pendency of such appeal except as otherwise provided.

(v) A copy of the final order of the hearing officer shall be mailed to the appellant(s) within three working days following the entry of a written order under this section. Unless otherwise stated in the order, such order shall be final and conclusive 10 days from the date of mailing thereof unless any party of record makes application to a court of competent jurisdiction for judicial review and stay of enforcement.

The result of this hearing may be appealed to district court. The court may consider mitigating factors to reduce or suspend fines and jail time.

(5) Additional Remedies. In addition to any other remedy provided by this chapter or under the Clarkston Municipal Code, the city may initiate injunction or abatement proceedings or any other appropriate action in courts against any person who violates or fails to comply with any provision of this chapter to prevent, enjoin, abate, and/or terminate violations of this chapter and/or to restore a condition which existed prior to the violation. In any such proceeding, the person violating and/or failing to comply with any provisions of this chapter shall be liable for the costs and reasonable attorneys’ fees incurred by the city in bringing, maintaining and/or prosecuting such action. [Ord. 1456 § 1, 2009.]

14.20.060 Inspections and investigations.

(1) Facility and Property Inspections. The enforcement officer shall be permitted to enter and inspect facilities under this chapter as often as may be necessary as ordered by district court, to determine compliance with this chapter including follow-up compliance. If a property owner has security measures in force which require proper identification and clearance before entry into its premises, the property or facility owner/operator shall make the necessary arrangements to allow access to the enforcement officer in conformity with the order of the court. The enforcement officer shall carry appropriate identification as an enforcement officer and display the identification to any person who requests identification.

(2) Facility and Property Access.

(a) Pursuant to order of the court, facility operators shall allow the enforcement officer ready access to all parts of the premises for the purposes of inspection, sampling, examination, and copying of records that must be kept under the conditions of an NPDES permit to discharge stormwater, and the performance of any additional duties as defined by state and/or federal law. This section does not bar entry if state and/or federal law mandates access or if there is an emergency as set forth in CMC 14.20.050(2).

(b) If the enforcement officer encounters any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled, and the obstacle is not moved at the request of an enforcement officer, the failure to remove the obstacle will be a violation. Unless the obstacle constitutes a safety feature, it shall be promptly removed by the property owner at the written or oral request of the enforcement officer and the obstacle shall not be replaced while the facility is under a duty to allow access for the above reasons or for follow-up inspections if illicit discharge or illicit connection has been found. The costs of clearing such access shall be borne by the property owner. [Ord. 1456 § 1, 2009.]

14.20.070 Regulatory consistency.

This chapter shall be construed to assure consistency with the requirements of the federal Clean Water Act and acts amendatory thereof or supplementary thereto, applicable implementing regulations, and the municipal NPDES permit and any amendments, revisions or reissuance thereof. No permit or approval issued pursuant to this chapter shall relieve a person of the responsibility to secure permits and approvals required for activities regulated by any other applicable rule, code, act, permit or ordinance. [Ord. 1456 § 1, 2009.]

14.20.080 Severability.

If any one or more section, subsections, or sentences of this chapter are held to be unconstitutional or invalid, such decision shall not affect the validity of the remaining portion of this chapter and the same shall remain in full force and effect. [Ord. 1456 § 1, 2009.]

14.20.090 Effective date.
