Project Overview
The Alliance has been working proactively and collaboratively with its Member agencies and the Washington State Department of Ecology to develop a delegated program that will serve the current and future needs of our community. The Alliance’s Salmon Creek Regional Wastewater Management System is a critical part of the community’s public infrastructure. Handling approximately 8 to 10 million gallons of wastewater per day, the system meets the federal thresholds for pretreatment program delegation, which are based on the size of the treatment plant and the presence of industrial users in the service area. As a result, Ecology has indicated its interest in delegating authority to administer the program locally. Delegation of authority involves a transfer of legal and regulatory authority and responsibilities for the program from the state (Ecology) to the local level (Alliance). The delegated program will provide local users with a more accessible and responsive program.

In the current framework, the pretreatment program is already being fully administered within the Alliance service area. Currently, Ecology maintains overall legal and regulatory authority for the program and coordinates with Clark Regional Wastewater District (District) to work with local users. Ecology responsibilities include issuing discharge permits to certain users, ensuring compliance with permit requirements and enforcement. The District currently administers a non-delegated pretreatment program, in coordination with the City of Battle Ground, that applies to all other industrial and commercial users of the wastewater system. District staff work with local businesses and Ecology to determine applicable pretreatment requirements for each user and to ensure that their wastewater discharge is in compliance with all federal and state pretreatment regulations. The District also engages with permitted users as the local point of contact and coordinates with and provides support to, Ecology as needed.
Current program requirements can be found in the local Sewer Use Ordinances for the District (Chapter 5.52) and the City of Battle Ground (Chapter 13.137).
Program delegation involves a transfer of program authority and oversight from the state to the local level. Practically, this means that upon approval of the delegated program, the Alliance will assume the role that Ecology plays today, serving as the “Control Authority” for the program. The Alliance will then work directly with users for all aspects of the program, including administering discharge permits. This will provide a more accessible and responsive program by providing a consistent, local point of contact for all users and a more efficient and streamlined permitting process.
