Project Description

Bonneville Power Administration, Pacific Northwest

Bonneville Power Administration (BPA) is a regional electric utility that markets wholesale electrical power to customers in the Pacific Northwest from 31 federal hydro projects in the Columbia River Basin, one non-federal nuclear plant and several other small non-federal power plants. BPA services over 300,000 square miles of territory and operates and maintains approximately 260 substations and 15,300 miles of transmission lines in the Pacific Northwest.

As a part of its process to continually improve its environmental performance of its power and transmission infrastructure, BPA installed Clara basic separators at several of its larger electrical substation and maintenance yards.

TARGETED POLLUTANTS: TSS, Oil & Grease

BACKGROUND

Bonneville Power Administration is a regional electric utility that markets wholesale electrical power to customers in the Pacific Northwest from 31 federal hydro projects in the Columbia River Basin, one non-federal nuclear plant and several other small non-federal power plants.  BPA services over 300,000 square miles of territory in Idaho, Oregon, Washington, western Montana and small parts of eastern Montana, California, Nevada, Utah and Wyoming, and operates and maintains approximately 260 substations and 15,300 miles of transmission lines.

Between 2008 and 2012, the utility installed the StormwateRx LLC Clara® basic stormwater separators at five of its electrical substations in Washington and Oregon as a part of its capital improvement program.

The Clara basic stormwater separator is an floatables/oil/water/grit separator specifically designed for industrial stormwater applications. With its patented four-chamber flow-through design, Clara effectively separates and retains oil, floatables and settable solids from stormwater runoff.  As the water passes from one chamber to the next, pollutants are captured and held within those chambers, preventing them from contaminating downstream receiving waters.

Clara includes an internal high flow bypass that allows storm events larger than the treatment design capacity to bypass without washing out accumulated oil and sludge.

PROJECT RESULTS:

This exceptional performance by the Zinc-B-Gone filters allowed for untreated stormwater from the plant grounds to comingle with the treated water and still be below the benchmark.
