Dominion has new plan to reduce emissions

Richmond, VA, Nov. 23, 2005 — Dominion, an American energy producer, announced that it plans to spend about $500 million to install additional emissions controls on coal- fired power stations in Virginia.

The installation of equipment to reduce sulfur dioxide, nitrogen oxide and mercury emissions is to meet stringent new emissions reductions required by the federal Clean Air Interstate and Mercury rules. The new equipment will be installed between 2008 and 2015.

The proposed new environmental controls follow more than $2 billion Dominion has invested or committed to since the 1990s in clean air improvements in Virginia through lowered emissions. The vast majority of these expenses have been borne by the company because of capped customer rates.

As part of the Virginia legislature’s effort to restructure the electric utility industry, Dominion in 1999 agreed to freeze its base rates at 1993 levels through 2010. Fuel rates were capped in 2004 until July 2007 when state law allows only one adjustment to reflect projected fuel costs through 2010.

With completion of all of the environmental construction by 2015, Dominion says it will have reduced its SO2 emissions by an average of more than 80 percent for all of its coal-fired units that serve Virginia. Nitrogen oxide emissions will decrease by 74 percent and mercury emissions by about 86 percent from 2000 levels said the company.

Control equipment installed by Dominion is said to reduce annual emissions of:

* SO2 from 272,650 tons in 2000 to nearly 54,000 tons in 2015.

* NOx from 93,300 tons to nearly 28,400 tons in the same period.

* Mercury from 2,100 pounds to about 270 pounds, also in the same period.
