The purpose of this section is to provide policy for the approval or denial of energy generation facilities with five (5) megawatt power generation capacity or more and intercounty and interstate energy terminal and transmission facilities. These facilities have unique development operations problems which must be scrutinized on a case-by-case basis. Siting, development or operation of such facilities have the potential to significantly impact the human and physical environment and, therefore, require careful study pursuant to the Clallam County Environmental Policy Code, Chapter 27.01 CCC, to assure adequate mitigation of adverse impacts. Some projects may be denied if certain adverse impacts cannot be adequately mitigated. All such facilities shall be conditional uses in all zones except as specifically provided in CCC 33.45.020.
