These discharges shall be permitted, if the amount of street wash and dust control water used is minimized. At active construction sites, street sweeping must be performed prior to washing the street. 5. Non-stormwater discharges covered by another NPDES permit. These discharges shall be in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations. 6. Other non-stormwater discharges.

Ifa discharger has security measures in force which require proper identification and clearance before entry into its premises, the discharger shall make the necessary arrangements to allow access to representatives of the city. 2. Premises owners, occupiers and their agents shall allow the city 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 this title and the performance of any additional duties as defined by state and federal law. 3. The city shall have the right to set up on any premises such devices as are necessary in the opinion of the Director to conduct monitoring and/or sampling of the stormwater discharge. 4. The city has the right to require premises owners, occupiers or their agents to install monitoring equipment as necessary. The monitoring equipment shall be maintained at all times in a safe and proper operating condition by the premises owners, occupiers, or their agents at its own expense. All devices used to measure stormwater flow and quality shall be calibrated to ensure their accuracy. 5. Any temporary or permanent obstruction to safe and easy access to the premises to be inspected and/or sampled shall be promptly removed by the premises owner, occupiers or their agents at the written or oral request of the city and shall not be replaced.

The Stormwater Manual sets forth approved Best Management Practices (BMPs). The owner or operator of a commercial or industrial establishment shall provide, at its own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal storm drain system or watercourses through the use of these structural and non-structural BMPs. Further, any person responsible for a property or premises, which is, or may be, the source of an illicit discharge, may be required to implement, at said person's expense, additional structural and non-structural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system. 14.21.110 Watercourse Protection. Every person owning or leasing property through which a watercourse passes, shall keep and maintain that part of the watercourse within the property free of trash, debris, and other obstacles that would pollute, contaminate, or significantly retard the flow of water through the watercourse. In addition, the owner or lessee shall maintain existing privately owned structures within or adjacent to a watercourse, so that such structures will not become a hazard to the use, function, or physical integrity of the watercourse. 14.21.120 Notification of Spills. Notwithstanding other requirements of law, as soon as any person responsible for a premises or operation, or responsible for emergency response for a premises or operation has information of any known or suspected release of materials, which are resulting or may result in illegal discharges or pollutants discharging into stormwater, the storm drain system, or water of the State flowing through the city, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release. In the event of such a release of hazardous materials, said person shall immediately notify emergency response agencies of the occurrence via emergency dispatch services. In the event of a release of non­ hazardous materials, said person shall notify the Public Works department in person or by phone or facsimile no later than the next business day. If the discharge of prohibited materials emanates from a commercial or industrial establishment, the owner or operator of such establishment shall also retain an on-site written record of the discharge and the actions taken to prevent its recurrence. 14.21.130 Suspension ofMS4 Access. A. Suspension due to Illicit Discharges in Emergency Situations. The Director may, without prior notice, suspend water service, sanitary sewer service, and/or MS4 discharge access to a person, when such suspension is necessary to stop an actual or threatened discharge which presents or may present imminent and substantial danger to the environment, or to the health or welfare of persons, or to the MS4. If the violator fails to comply with a suspension order issued in an emergency, the Director may take such steps as deemed necessary to prevent or minimize damage to the MS4 , or to minimize danger to persons. B. Suspension due to the Detection of Illicit Discharge. Any persons discharging to the MS4 in violation of this chapter may have their water service, sanitary sewer service and/or MS4 access terminated, if such termination would abate or reduce an illicit discharge. The Director will notify a violator of the proposed termination of its water service, sanitary sewer service, and/or MS4 access. 14.21.140 Enforcement. Enforcement of the provisions of this chapter shall be as set forth in Title 4 MMC. Included in the city's abatement costs that may be recovered under the provisions of Title 4 MMC are the costs of abatement, sampling, or monitoring costs incurred if a violator fails to comply with the provisions of this chapter. 14.21.150 Compensatory action. In lieu of enforcement proceedings, penalties, and remedies authorized by MMC Title 4 and this chapter, the director may impose upon a violator alternative compensatory actions, including but not limited to, such remedial actions as storm drain stenciling, attendance at compliance workshops, and creek cleanup. 14.21.160 Severability. The provisions of this chapter are hereby declared to be severable. If any provision, clause, sentence, or paragraph of this chapter or the application thereof to any person, establishment, or circumstances shall be held invalid, such invalidity shall not affect the other provisions or application ofthis chapter. 14.21.170 Ultimate Responsibility. The standards set forth herein and promulgated pursuant to this chapter are minimum standards. Compliance with the standards established under this chapter does not relieve persons from any responsibility or obligation imposed pursuant to any other local, state, or federal regulation.
