Section 173-360-520. Physical criteria for environmentally sensitive areas.

Except as provided for in WAC 173-360-510(3), environmentally sensitive areas shall be designated based on the criteria established by the department. One or more of the criteria shall be present and the department will evaluate the application for designation based on the overall sensitivity of the environment and consistency with WAC 173-360-510(1). Those criteria include, but are not limited to:

(1) Groundwater that is vulnerable to pollution because of specific hydrogeological characteristics, including but not limited to, recharge areas, permeability, precipitation, direction and quantity of groundwater flow, and presence of aquitards;

(2) Proximity to wetlands;

(3) Being located within a 100-year flood plain; or

(4) Proximity to other surface waters that can be shown to have a hydrogeologic link to such groundwater as is described in subsection (1) of this section, underlying an area where underground storage tank systems are installed or may be installed, if a leak from such a system has a reasonable chance of reaching groundwater.
