Washington Group Gets Contract For 'Scrubbers' At Detroit Edison Plant

'Scrubbers' designed to cut emissions of sulfur dioxide by 97 percent.

Washington Group International Inc. said Wednesday it has been chosen to provide services for an environmental retrofit project at a Detroit Edison power plant in Monroe, Mich.

Washington Group, one of the world's largest construction and engineering firms, will provide engineering, procurement, and construction services for installation of flue gas desulphurization systems - known as ''scrubbers'' - on two of the plant's generating units.

The cost of the project totals more than $500 million.

The scrubbers are designed to reduce sulfur dioxide emissions from each generating unit by 97 percent. When operated in combination with selective catalytic reduction systems, the scrubbers also will reduce mercury emissions by more than 80 percent, Washington Group said.

Scrubber construction already has begun on one unit and is expected to be finished in December 2008. Construction on the second unit will be completed in 2010, the company said.
