(1) A person may not install or operate a large on-site sewage system without an operating permit as provided in this chapter after July 1, 2009. The owner of the system is responsible for obtaining a permit.

(2) The department shall issue operating permits in accordance with the rules adopted under RCW 70A.115.040.

(3) The department shall ensure the system meets all applicable siting, design, construction, and installation requirements prior to issuing an initial operating permit. Prior to renewing an operating permit, the department may review the performance of the system to determine compliance with rules and any permit conditions.

(4) At the time of initial permit application or at the time of permit renewal the department shall impose those permit conditions, requirements for system improvements, and compliance schedules as it determines are reasonable and necessary to ensure that the system will be operated and maintained properly. Each application must be accompanied by a fee as established in rules adopted by the department.

(5) Operating permits shall be issued for a term of one year, and shall be renewed annually, unless the operator fails to apply for a new permit or the department finds good cause to deny the application for renewal.

(6) Each permit may be issued only for the site and owner named in the application. Permits are not transferable or assignable except with the written approval of the department.

(7) The department may deny an application for a permit or modify, suspend, or revoke a permit in any case in which it finds that the permit was obtained by fraud or there is or has been a failure, refusal, or inability to comply with the requirements of this chapter or the standards or rules adopted under this chapter. RCW 43.70.115 governs notice of denial, revocation, suspension, or modification and provides the right to an adjudicative proceeding to the permit applicant or permittee.

(8) For systems with design flows of more than fourteen thousand five hundred gallons per day, the department shall adopt rules to ensure adequate public notice and opportunity for review and comment on initial large on-site sewage system permit applications and subsequent permit applications to increase the volume of waste disposal or change effluent characteristics. The rules must include provisions for notice of final decisions. Methods for providing notice may include email, posting on the department's internet site, publication in a local newspaper, press releases, mailings, or other means of notification the department determines appropriate.

(9) A person aggrieved by the issuance of an initial permit, or by the issuance of a subsequent permit to increase the volume of waste disposal or to change effluent characteristics, for systems with design flows of more than fourteen thousand five hundred gallons per day, has the right to an adjudicative proceeding. The application for an adjudicative proceeding must be in writing, state the basis for contesting the action, include a copy of the decision, be served on and received by the department within twenty-eight days of receipt of notice of the final decision, and be served in a manner that shows proof of receipt. An adjudicative proceeding conducted under this subsection is governed by chapter 34.05 RCW.

(10) Any permit issued by the department of ecology for a large on-site sewage system under chapter 90.48 RCW is valid until it first expires after July 22, 2007.

(11) Systems required to meet operator certification requirements under chapter 70A.212 RCW must continue to meet those requirements as a condition of the department operating permit.
