(1) The county may attach conditions to a permit or approval for a proposal. The conditions shall be related to specific adverse environmental impacts clearly identified in an environmental document on the proposal and shall be stated in writing by the decision maker. The decision maker shall cite the county SEPA policy that is the basis of any condition under this chapter. A written document shall state the mitigation measures, if any, that will be implemented as a part of the decision, including any monitoring of environmental impacts. The document may be the permit or approval itself, or may be combined with other agency documents, or may reference relevant portions of environmental documents.

(2) The mitigation measures included in the conditions shall be reasonable and capable of being accomplished.

(3) Responsibility for implementing mitigation measures may be imposed upon an applicant only to the extent attributable to the identified adverse impacts of the proposal. Voluntary additional mitigation may occur.

(4) The county, before requiring mitigation measures, shall consider whether local, state, or federal requirements and enforcement would mitigate an identified significant impact.

(5) The conditions shall be based on one or more policies in SCC 30.61.230 and cited in the permit or approval, or other decision document.

(6) If, during project review, the county determines under RCW 43.21C.240 that the requirements for environmental analysis, protection, and mitigation measures in the county’s development regulations, comprehensive plan, or in other applicable local, state, or federal laws or rules, provide adequate analysis of and mitigation for the specific adverse environmental impacts of the project action, the county shall not impose additional mitigation under this chapter.
