26.02.060 Critical aquifer recharge areas.
(1) For the purposes of this section, “high susceptibility areas” are defined as the Town limits which incorporate all wellhead protection areas.
(2) In areas designated as high susceptibility for aquifer contamination (areas within the wellhead protection area and as defined by critical aquifer recharge area criteria) all uses shall be connected to the Town’s sewer system.
(3) For uses locating within the critical aquifer recharge area and requiring site plan review, a disclosure form indicating activities and hazardous materials that will be used shall be provided for review and approval. The Town shall have the right to limit actions within wellhead protection areas and/or critical aquifer recharge areas in consultation with experts and/or regulating agencies as required for the proposed use.
(4) Impervious surfaces shall be minimized within the critical aquifer recharge area.
(5) Best management practices as defined by state and federal regulations shall be followed by commercial and industrial uses located in the critical aquifer recharge areas to ensure that potential contaminants do not reach the aquifer.
(6) A spill prevention and emergency response plan shall be prepared and submitted for review and approval by the Town and fire district.
(7) The following uses shall be prohibited within critical aquifer recharge areas:
(a) Landfills, including hazardous waste, municipal solid waste, special waste, wood waste, inert waste, and demolition waste.
(b) Underground injection wells, except for Class V wells that have been determined to be free of contamination potential and which are designed and maintained in keeping with the latest version of the State Department of Ecology’s Storm Water Management Manual for Eastern Washington.
(c) Mining of metals and hard rock. Sand and gravel mining shall also be prohibited from critical aquifer recharge areas rated as highly susceptible or vulnerable.
(d) Wood treatment facilities that allow any portion of the treatment process to occur over natural or manmade permeable surfaces.
(e) Facilities that store, process, or dispose of radioactive substances.
(f) Activities that would significantly reduce the recharge to aquifers currently or potentially used as a potable water source.
(g) Activities that would significantly reduce the recharge to aquifers that are a source of significant baseflow to a regulated stream.
(h) Activities that are not connected to an available sanitary sewer system in areas associated with sole source aquifers. (Ord. 474-N, §2, 2020; Ord. 338-N, §2, 2007)
