A settlement is an agreement among two or more parties. Applicants, member agencies, and the counsel for the environment may enter into a settlement concerning any matter. Intervenors may enter into a settlement agreement subject to any limits and conditions specified in the council's order granting intervention. Settlements are filed with the council as a proposed resolution of the issues addressed in the agreement.

(1) Full settlement. An agreement of all parties that would resolve all issues in a proceeding may be presented as a full settlement for council review.

(2) Partial settlement. An agreement of all parties on fewer than all issues in a proceeding may be presented as a partial settlement for council review, and remaining matters may be the subject of further council proceedings.

(3) Multiparty settlement. An agreement of some but not all parties on one or more issues may be offered as their position in the proceeding along with the evidence that they believe supports it.

(4) Notice to council. Parties must advise the council if they reach a full, partial, or multiparty settlement and may suggest preferred procedural alternatives for review of the settlement, subject to the requirements of WAC 463-30-253 and 463-30-254. The council will determine the appropriate procedure in each proceeding consistent with the requirements of WAC 463-30-253 and 463-30-254.
