All operations shall adopt the following best management practices to ensure their operations minimize potential risks to water resources:

A. Pollution Prevention. The owner/operator shall implement all applicable source control BMPs from the Stormwater Manual to prevent potentially harmful materials from coming into contact with stormwater. Potentially harmful materials shall be separated and prevented from entering stormwater drainage systems, septic systems, and drywells.

B. Hazardous Materials Management. Hazardous materials shall be managed so that they do not threaten human health or the environment or enter water resources.

C. Hazardous Material Releases. All hazardous materials that have been released shall be contained and abated immediately, and the hazardous materials recycled or disposed of properly. The city shall be notified of any release of hazardous materials that may impact water resources as soon as possible but no later than 24 hours after the release. The Stormwater Manual provides applicable operational BMPs for spills of oils and hazardous substances.

D. Maintaining Stormwater Facilities. Stormwater facilities, including, but not limited to, catch basins, wet ponds and vaults, biofilters, settling basins, bioretention, pervious pavements, and infiltration systems, shall be cleaned and maintained by the responsible party designated in VMC 14.25.209 according to the applicable operational BMPs for the maintenance of stormwater, drainage and treatment systems in the Stormwater Manual.

E. Decommissioning Water Wells. Any water well which is unusable, abandoned or whose use has been permanently discontinued or which is in such disrepair that its continued use is impractical or is an environmental, safety or public health hazard shall be decommissioned according to the provisions of WAC 173-160-381.

F. Operation Closure. At the closure of an operation, all hazardous materials shall be removed from the closing portion of the operation and disposed of in accordance with local, state and federal laws. (Ord. M-4372 § 5, 2022; Ord. M-4179 § 55, 2016; Ord. M-3920 § 4, 2009; Ord. M-3600, 2002)
