E. Notification To City: As soon as any person responsible for a facility or operation has information of any known or suspected release of materials that are resulting or may result in illegal discharges or pollutants discharging into the storm sewer system, said person shall take steps to ensure the discovery, containment, and cleanup of such release. In the event of a release of hazardous materials, said person shall immediately notify emergency response agencies of the occurrence. In the event of a release of nonhazardous materials, said person shall notify the city no later than the next business day.
F. Access To Buildings And Sites For Inspection, Monitoring And Dye Testing:
1. The city has the right to require the stormwater discharger to install monitoring equipment as necessary.
2. Unreasonable delays in allowing the city access to a building or site is a violation of this chapter.
3. If the city has been refused access to any part of the building or site from which stormwater is discharged, and is able to demonstrate probable cause to believe that there may be a violation of this section, or that there is a need to inspect or sample to verify compliance with this chapter or any order issued hereunder, or to protect the overall public health, safety, and welfare of the community, then the city may seek issuance of a search warrant from any court of competent jurisdiction.
G. Suspension Of Storm Sewer System Access:
1. The city may, without prior notice, suspend storm sewer system discharge access to any building or site 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 storm sewer system or surface waters.
2. Failure to comply with a suspension order issued in an emergency will result in any process deemed necessary to prevent or minimize damage to the storm sewer system or surface waters, or to minimize danger to persons.
3. Any building or site with discharge to the storm sewer system that is in violation of this chapter may have storm sewer system access terminated if such termination would abate or reduce an illicit discharge. (Ord. 884, 10-3-2011)
