<br /> <br />Kittitas County Shoreline Master Program <br />Chapter 5 82 <br />March 7, 2016 <br />Kittitas County Board of County Commissioners Shoreline Master Program Adopting Ordinance <br />Kittitas County Shoreline Master Program Exhibit A | March 2016 | Page 82 of 339 <br />groundwater monitoring data, wellhead protection areas, depth to groundwater, <br />topography (i.e., slopes), and locally adopted groundwater protection plans and <br />studies. Land classified as having a high, medium, or low aquifer recharge potential <br />shall also be classified as having a high, medium, or low susceptibility to <br />contamination of an underlying aquifer, respectively. Based on these criteria, the <br />potential for recharging aquifers or transmitting contaminants to the underlying <br />aquifer is greatest where the aquifer is close to the ground surface, where ground <br />surface slopes are minimal, and where the recharge potential of the soils and/or <br />surficial geologic material is greatest. All wellhead protection areas shall be <br />designated as highly susceptible critical aquifer recharge areas. Wellhead Protection <br />Areas are the areas defined by the boundaries of the 10-year time of ground water <br />travel, in accordance with WAC 246-290-135. <br /> <br />V. Regulations—critical aquifer recharge areas protection standards <br /> <br />1. Protection standards for critical aquifer recharge areas have been incorporated into <br />the water quality regulations in Section 5.6 and into the provisions for specific <br />shoreline uses in Chapter 4. Such standards shall be considered the minimum <br />necessary to protect critical aquifer recharge areas. <br /> <br />2. New use and development in a critical aquifer recharge area shall meet the following <br />standards: <br />a. The proposed use and/or development will not cause contaminants to enter the <br />aquifer and will not significantly adversely affect the recharging of the aquifer. <br />b. The proposed use and/or development must comply with applicable water source <br />protection requirements of the Federal Environmental Protection Agency (EPA), <br />Washington State Department of Health, and the Kittitas County Health <br />Department. <br />c. The proposed use and/or development must be designed and constructed in <br />accordance with applicable stormwater management standards <br /> <br />3. When located within an area of medium or high aquifer susceptibility, <br />aboveground/underground storage tanks or vaults for the storage of hazardous <br />substances, animals wastes, sewage sludge, fertilizers, or other chemical or <br />biological hazards or dangerous wastes as defined in WAC Chapter 173-303, or any <br />other substances, solids, or liquids in quantities identified by Kittitas County Public <br />Health, consistent with WAC 173-303, as a risk to groundwater quality, shall be <br />designated and constructed so as to: <br />a. Prevent the release of such substances to the ground, groundwaters, or surface <br />waters; <br />b. Be contained or enclosed by an impervious containment area with a volume <br />greater than the volume of the storage tank or vault to avoid an overflow of the <br />containment area; <br />c. Provide for release detection;
