Kittitas County Shoreline Master Program <br />L Mining operations should be located, designed, and managed so that other <br />appropriate uses are not subjected to substantial or unnecessary adverse impacts <br />from noise, vibration, odor, dust or other effects of the operation. The operator may be <br />required to implement measures such as buffers, limited hours, or other mitigating <br />measures to minimize adverse impacts. <br />B. Requlations <br />1. Mining below the OHWM of a river shall be permitted only when: <br />a. Removal of specified quantities of sand and gravel or other materials at specific <br />locations will not adversely affect the natural processes of gravel transportation <br />for the river system as a whole; and <br />b. The mining and any associated permitted activities will not have significant <br />adverse impacts to habitat for priority species nor cause a net loss of ecological <br />functions of the shoreline. <br />c. Determination of whether the two provisions above have been met shall be made <br />consistent with RCW 90.58.100(1) and WAC 173-26-201(2)(a). Such evaluation <br />of impacts should be appropriately integrated with relevant environmental review <br />requirements of SEPA (RCW Chapter 43.21C) and the SEPA rules (WAC <br />Chapter 197-11). <br />d. ln considering renewal, extensionsorreauthorization of gravel barand otherin- <br />channel mining operations in locations where they have previously been <br />conducted, local government shall require compliance with this subsection (1) to <br />the extent that no such review has previously been conducted. Where there has <br />been prior review, local government shall review previous determinations <br />comparable to the requirements of this Section to assure compliance with this <br />subsection(1) under current site conditions. <br />e. The provisions of this Section do not apply to dredging of authorized navigation <br />channels when conducted in accordance with WAC 173-26-231(3)(f). <br />2. Mining within any channel migration zone that is within the shoreline jurisdiction shall <br />require a shoreline conditional use permit. <br />3. Mining shall not be permitted in designated fish and wildlife habitat areas except as a <br />part of an approved flood control program or in conjunction with a habitat restoration <br />or enhancement plan, provided that such activities are demonstrated to be water- <br />dependent. A determination of water dependency shall be based on an evaluation of <br />geologic factors such as the distribution and availability of mineral resources for that <br />jurisdiction, and a need for such mineral resources, economic, transportation, and <br />land use factors. This demonstration may rely on analysis or studies prepared for <br />purposes of comprehensive plan designations, and may be integrated with any <br />relevant environmental review conducted under SEPA (RCW Chapter 43.21C), or <br />othenrvise be shown in a manner consistent with RCW 90.58.100(1) and WAC 173-26- <br />201 (2)(a). <br />Chapter 6 <br />March 7,2016 <br />118
