Notwithstanding other requirements of law, as soon as any person responsible for a facility or operation, or responsible for emergency response for a facility or operation, has information of any known or suspected release of materials resulting in, or that may result in, illegal discharges or pollutants discharging into stormwater, the storm drain system, or water of the U.S., that person shall take all necessary steps to ensure the discovery, containment and cleanup of the release. In the event of a release of hazardous materials, the person shall immediately notify emergency response agencies of the occurrence via emergency dispatch services. In the event of a release of non-hazardous materials, the person shall notify the public works director, or his or her designee, in person or by phone or facsimile, no later than the next business day. Notifications in person or by phone shall be confirmed by written notice, addressed and mailed to the city within three business days of the phone notice. If the discharge of prohibited materials emanates from a commercial or industrial establishment, the owner or operator of that establishment shall also retain an on-site written record of the discharge, and the actions taken to prevent its recurrence. Such records shall be retained for at least three years. (Ord. 1397.18, § 1 (part), 2019)
