Clover plant a top gas emitter

For the first time, county residents can now keep track of who is emitting greenhouse gases with the U. S. Environmental Protection Agency databases and searchable online map released earlier this month. The comprehensive greenhouse gas data reports emissions of carbon dioxide, methane and nitrous oxide directly from 6,700 large facilities and suppliers across the country.

A view of the easily accessible data indicates Clover Power Station, located on Route 92 in Clover, is this area’s highest greenhouse gas emitter — and the second largest in the state.

Gases emitted include carbon dioxide — 6,200,420; methane at 14,224; and nitrous oxide at 30,545; for a total greenhouse gas emission of 6,245,189.

According to the data, the Clover Power Station employs technologies to directly monitor some or all of its emissions.

The Clover Power Station website states the facility has the distinction of being “one of the cleanest coal-fired power station’s in the nation.”

Clover’s two units, which began operating in 1995 and 1996, burn an average of 3,786 tons of coal per day.

“The station uses the best known pollution control technologies to reduce the wastes it produces and minimize its impact on the environment,” according to the station’s website.

“Approximately one third of Clover Power Station’s total $1.2 billion cost is devoted to environmental protection, to controlling sulfur dioxide, nitrogen oxide, fly ash and other unwanted materials produced in the generation of electricity. Burning coal produces fly ash, a powder-like ash. Almost all of it is captured in giant filter facilities called bag-houses,” the website continues.

It further explains Clover Power
Station is equipped with limestone scrubber technology. Limestone powder is mixed with water and sprayed over the flue emissions.

“The sulfur dioxide in the flue gas mixes with the limestone slurry and falls to the bottom of the scrubber vessel as liquid gypsum. The gypsum slurry is then pumped to the primary dewatering system where solids are removed.

“The gases produced by the combustion process are carefully controlled. Low nitrogen oxide burners in the station reduce the NOx normally produced in burning coal. Giant stainless steel reaction vessels called scrubbers remove almost all the sulfur dioxide emissions,” according to the power station’s website.

Data found on the Greenhouse Gas Reporting Program indicates the state’s largest greenhouse gas emitter is Chesterfield Power Station in Chester with a total emission of 7,195,433.

Other gas emitters in the region include Goodyear tire manufacturing plant in Danville, Dominion Virginia Power’s Altavista Power Station and Owens-Brockway Glass Container facility.

In neighboring North Carolina, Mayo Electric Generating Plant has a total greenhouse gas emission of 4,784,984, while the Roxboro Steam Electric Plant in Semora has a total emission of 14,603,523 in carbon dioxide, methane and nitrous oxide.

“Thanks to strong collaboration and feedback from industry, states and other organizations, today we have a transparent, powerful data resource available to the public,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “The GHG Reporting Program data provides a critical tool for businesses and other innovators to find cost- and fuel-saving efficiencies that reduce greenhouse gas emissions and foster technologies to protect public health and the environment.”
