Bonney Lake adopts ordinance creating local wastewater pretreatment rules tied to Sumner

Bonney Lake City Council on May 14 adopted Ordinance D24-48, adding Chapter 13.14 to the municipal code to establish wastewater pretreatment regulations for users of the publicly owned treatment works under an interlocal agreement with the City of Sumner. The ordinance formalizes local rules and is intended to align Bonney Lake’s code with Sumner’s existing wastewater-treatment regulations.

Council members and staff said the change responds to requirements coming from the state and will allow local coordination on permitting and inspections. Council discussion noted that most local businesses are expected to be in compliance and that creating a Bonney Lake chapter will let staff and Sumner’s inspector jointly advise new businesses on equipment and permit needs before they discharge to the sewer system. Staff who participated in the discussion included Andrea (inspector), Michael Gosen and Jay Swift.

City staff described the practical effect as localized administration of pretreatment permits: rather than relying solely on the state Department of Ecology, local utility staff and the Sumner inspector will work together to identify required equipment and compliance steps. The ordinance includes standard severability and correction clauses and establishes an effective date in the ordinance text.

The council voted to adopt the ordinance by voice vote. The transcript records the ordinance introduced by the clerk, staff answering council questions, and no further public comment on the matter during the meeting.

The action implements an interlocal agreement with the City of Sumner and is intended to reduce regulatory friction for businesses while protecting the wastewater treatment process.
