Odors are usually not perceptible beyond the boundaries of the Columbia Boulevard Wastewater Treatment Plant. Occasionally, plant maintenance projects will release odors that may be perceptible in neighborhoods surrounding the plant. Environmental Services issues advance notices of maintenance projects that may result in odors outside the plant’s boundaries.
