<br /> <br />35 <br /> <br />Kittitas County Public Health as a risk to groundwater quality, shall be designed and <br />constructed to: <br />a. Prevent the release of such substances to the ground, ground waters, or surface <br />waters; <br />b. Include an impervious containment area with a volume greater than the volume of <br />the storage tank or vault to avoid an overflow of the containment area; <br />c. Provide for release detection; <br />d. Provide written spill response and spill notification procedures to the local fire district; <br />e. Use material in the construction or lining of the storage containment area which is <br />compatible with the substance to be stored to protect against corrosion or leakage, or <br />otherwise designed in a manner to prevent the release or threatened release of any <br />stored substance; and <br />f. Comply with WAC 173-303 and 173-360 as well as International Building Code <br />requirements. <br />2. Commercial vehicle repair, servicing, and salvaging facilities. Vehicle repair and <br />servicing activities shall be conducted over impermeable pads and within a covered structure <br />capable of withstanding normally expected weather conditions. Chemicals used in the <br />process of vehicle repair, servicing, and salvaging must be stored in a manner that protects <br />them from weather and provides containment should leaks occur. Dry wells shall not be <br />allowed on sites used for vehicle repair, servicing, and salvaging. Dry wells existing on the <br />site prior to facility establishment must be abandoned using techniques approved by the <br />Washington State Department of Ecology prior to commencement of the proposed <br />development. <br />3. Reclaimed wastewater. Use of reclaimed wastewater must be in accordance with adopted <br />water or sewer comprehensive plans that have been approved by Ecology. <br />4. Other regulated uses. Protection standards for other uses regulated under KCC <br />17A.03.030 shall be based on analysis and recommendations contained in the hydrogeologic <br />reports required for specific projects. <br /> <br /> <br />17A.03.050 Reporting. <br />1. When required. Except for storage tanks, all uses listed in KCC 17A.03.030 require County <br />review and approval of a special hydrogeological assessment prepared by a qualified <br />professional. <br />2. Contents. The hydrogeological assessment shall include the general critical areas report <br />requirements of KCC 17A.01.080 in addition to the following: <br />a. Geologic setting and soils information for the site and surrounding area; <br />b. Water quality data, including pH, temperature, dissolved oxygen, conductivity, <br />nitrates, and bacteria; <br />c. Location and depth of perched water tables; <br />d. Recharge potential of site (permeability/transmissivity); <br />e. Hydrologic budget; <br />f. Local groundwater flow, direction, and gradient; <br />g. Location, depth, and other water quality data on the three (3) shallowest wells or <br />springs located within one thousand (1,000) feet of the site; <br />h. Potential impacts to wellhead protection areas located within the site; <br />i. Surface water locations within one thousand (1,000) feet of the site; <br />j. Discussion of the effects of the proposed development on groundwater quality and <br />quantity; <br />k. Recommendations on appropriate mitigation, if any, to assure that there shall be no <br />measurable exceedance of minimum state groundwater quality standards or <br />measurable reduction in available quantity of groundwater; <br />l. Emergency management plan; and
