Awards/Recognition

In September 2006, the Potomac River Generating Plant earned ISO 14001:2004 certification for our Environmental Management System. In simple terms, this certification means we're “doing it right” in our approach to sound environmental management, following an internationally endorsed framework of standards. ISO (International Organization for Standardization) is the world's largest developer of standards. Only a small percentage of industrial and corporate facilities in the United States have earned this distinction — and we are proud to be among them. In addition to Potomac River, Mirant's Chalk Point and Morgantown power plants in Maryland are ISO 14001:2004 certified as are our Brandywine and Faulkner ash storage facilities.

All of Mirant's Mid-Atlantic operations are Wildlife Habitat Council (WHC) certified and have received national recognition for their contributions to wildlife habitat conservation. Efforts include providing artificial nesting structures for bluebirds and finches, and planting native trees, shrubs, and aquatic plants.

Potomac River Generating Plant is critical to meeting the high demand of electricity required in and around our nation's capital. Yet what was once an isolated facility is now juxtaposed in every direction with newer development and dense population. Balancing the various needs of the plant's constituency is a job Potomac River employees take seriously.

A major focus here is to improve air quality around the plant. Since acquiring Potomac River in 2000, Mirant has made several major improvements to minimize emissions and operate more cleanly. From 2005-2006, we:

• Reduced sulfur dioxide (SO2) emissions 64%;
• Decreased nitrous oxide (NOx) 24.7%; and
• Maintained a 5% level of opacity — far below federal requirements of 20%.

Mirant's four plants in the D.C. area, including Potomac River, comply with operating permit emission limits.

Environmental Highlights

Community Outreach

Potomac River Clean Up

In partnership with the National Park Service and local community groups, the station hosts clean up events twice a year along the Potomac River. Each year our employees have hauled away several hundred pounds of debris from the river and shoreline. In March 2007, our employees participated in the Annual Potomac River Watershed Clean-up, cleaning the river of over 66 bags of trash, four tires, and other items.

Holiday Giving

The plant "adopted" a family of six children for a holiday program coordinated by the Alexandria Human Services Department. Employees provided all the gifts on the kids' wish lists, as well as groceries and a retail gift certificate for Mom.

College Scholarships

Mirant is in the second year of its five-year Mirant Alexandria Scholarship program, a partnership with Washington Metropolitan Scholars. Mirant is awarding $250,000 in scholarships to a total of 50 Alexandria students through 2010.

The recipients, nominated by their high school principals, are selected based on their academic achievements and potential in their field of study.
