It is the intent of this chapter to safeguard groundwater resources <br />against contaminants from alterations and development. <br /> <br />17A.03.020 Designation, and Mapping. <br />1. Classification and Designation. Critical aquifer recharge areas are areas of unconsolidated <br />deposits within the Roslyn and Kittitas Basins, and all Group A well head protection areas, as <br />shown on the County’s critical areas maps. All projects proposing uses listed in 17A.03.030 <br />that are within the unconsolidated deposits within the Kittitas and Roslyn basins, or within a <br />Group A wellhead protection area shall be reviewed for potential hazards to groundwater. <br />2. Mapping. The designated Critical Aquifer Recharge Areas are mapped in the Kittitas County <br />Critical Areas Ordinance Critical Aquifer Recharge Area Map. Permit reviews will be based <br />on the mapped critical area designation shown on the critical areas maps.. <br /> <br />17A.03.030 Applicability. <br />This chapter regulates the following uses when located in a critical aquifer recharge area: <br />1. Storage tanks; <br />2. Commercial vehicle repair, servicing, and salvaging facilities; <br />3. Reclaimed wastewater; <br />4. New landfills, including hazardous or dangerous waste, municipal solid waste, special waste, <br />wood waste of more than two thousand (2,000) cubic yards, and inert and demolition waste <br />landfills; <br />5. Injection wells used for disposal of waste products including, but not limited to, stormwater <br />discharge, hazardous or radioactive waste, or industrial waste; <br />6. Wood treatment facilities that allow any portion of the treatment process to occur over <br />permeable surfaces (both natural and manmade); <br />7. Commercial coal,ore mining operations, and natural gas exploration and extraction; <br />8. Facilities that store, process, or dispose of chemicals containing perchloroethylene (PCE) or <br />methyl tertiary butyl ether (MTBE) or other chemicals with the potential to contaminate <br />groundwater; <br />9. Dairy farms and feedlots; <br />10. Man-made stormwater detention or infiltration ponds, manure lagoons, and irrigation ponds; <br />and <br />11. Any other alteration or development that the Director determines – based on best available <br />science– is likely to have a significant adverse impact on ground water. <br /> <br /> <br />1. 17A.03.040 Protection Standards.Storage tanks. Aboveground and underground storage <br />tanks or vaults used for the storage of hazardous substances, animal wastes, sewage <br />sludge, fertilizers, other chemical or biological hazards, dangerous wastes as defined in <br />WAC Chapter 173-303, or any other substances, solids, or liquids in quantities identified by
