Mason County asks state for feasibility funding as Bremerton seeks sewer service for Puget Sound Industrial Center

Mason County commissioners agreed to press the Washington Department of Commerce for funding to study whether the county should provide sewer service to the southern portion of the Puget Sound Industrial Center — a request prompted by the City of Bremerton’s recent planning documents and a mayoral request for capacity.

The county’s planning and public works staff briefed commissioners on several draft studies and on a Bremerton proposal that calls for a phased approach: an initial volume of flow served by Mason County and later capacity served by Bremerton. County staff and multiple commissioners said they need more detailed cost and design data before entering any long-term interlocal agreement.

“That money is going to have to either come from them or from our budget,” said a county staff member summarizing the practical trade-offs. Commissioners asked staff to ask Commerce what the agency needs to consider the project eligible for the state funding that Bremerton has sought. The briefing noted a Commerce award already routed to Bremerton and a separate $1.4 million planning request for Mason County; commissioners said they want the state to clarify what form of commitment Commerce expects in return.

Why it matters: The county’s Belfair wastewater system has limited spare capacity, and serving industrial development north of the county line could require plant upgrades, new conveyance and reassessment of how reclaimed water, spray fields and other disposal methods are managed. Commissioners flagged potential environmental and fiscal risks — including industrial wastewater quality, long-term obligations and the effect on county tax revenues — if the county were to accept a firm, indefinite obligation without fiscal safeguards.

Details and next steps: County staff described the Bremerton draft sewer plan and a Kitsap regional economic-growth analysis and said both raise unanswered questions about the scale and timing of build-out in PSIC. Commissioners asked staff to: - Contact the Department of Commerce and ask whether a simple commitment to evaluate service, plus a state-funded feasibility study, would satisfy the grant conditions; and - Prepare a Mason-County-led feasibility scope (an approximately funded study) that would calculate capital and operating costs, potential remedies for negative fiscal impacts, and environmental safeguards to present back to the board.

Commissioner comments reflected divergent concerns. One commissioner said any commitment must be “financially feasible” for Mason County and warned against entering an open-ended obligation; another said she wanted a county-commissioned ILA draft to protect county interests before negotiating with Bremerton. Several commissioners emphasized that they will not sign a long-term commitment until the county can see detailed cost and capacity analyses.

The county will pursue clarification from Commerce and then use state funding, if provided, to complete the technical feasibility work needed to draft a protective interlocal agreement or to decline service if the numbers do not support it.
