TCWTP Facilities Plan

The Oregon Department  of Environmental Quality (DEQ) often requires wastewater utlities to develop or update a facilities plan during a wastewater discharge permit renewal process. Environmental Services has applied for renewal of the Tryon Creek Wastewater Treatment Plant (TCWTP) Waste Discharge Permit and has updated the TCWTP Facilities Plan to support that permit renewal process.

The facilities plan identifies wastewater facilities that will reliably meet discharge permit requirements and future capital improvement projects at the TCWTP.

Land uses in the Foothills area around the plant may change in the future. The updated Facilities Plan provides an ongoing framework for the plant to continue to be a good neighbor.

Oversight Committee

The decision-making body for the TCWTP Facilities Plan update was an Oversight Committee which consisted of the Lake Oswego Mayor and City Manager, and the Commissioner in charge and the Director of Portland's Bureau of Environmental Services.

Advisory Committee

A nine-member Citizens Advisory Committee (CAC) advised the Oversight Committee and the Facilities Plan update project team. Lake Oswego and Environmental Services appointed members to serve on the CAC.
