RECYCLING AND REUSING COAL ASH

DAN RIVER, VIRGINIA

• In February 2014, more than 80,000 tons of

coal ash spilled into the Dan River in Virginia.

• The amount of coal ash that poured into the

Dan River was equal to the weight of the

Washington Monument aboveground.

YEARLY PRODUCTION

• Every year, the more than 500 coal-fired power

plants in the U.S. produce 140 million tons

of coal ash.

• Millions of tons of coal ash are stored in ponds,

landfills and abandoned mines.

• Most of these disposal sites lack the safeguards

necessary to keep the waste from leaking out.

COAL-FIRED POWER PLANTS AND COAL ASH

are the second largest industrial

waste stream in the country.

HEALTH RISKS

• At least 535 coal ash ponds operate without a

simple liner to prevent toxic chemicals and

heavy metals from leaching into the ground and

nearby water sources.

• People who live within one mile of unlined coal

ash storage ponds can have a one in 50 risk of

cancer.

• Living near a wet coal ash storage pond is more

dangerous to a person’s health than smoking a

pack of cigarettes a day.

COAL ASH GENERALLY CONTAINSarsenic, lead, mercury, selenium,

aluminum, barium, boron

and chlorine.

THERE ARE 1,425 COAL ASH PONDS AND LANDFILLS

in 37 states.

COAL ASH CAN BE RECYCLED

43% of Coal Ash is Recycled in Construction Materials

More than 70 million tons of ash is dumped into pits and landfills

THE RCRA

• Up until the end of 2014, coal ash fell under the

Resource Conservation and Recovery Act (RCRA)

of 1976 but was classified as “exempt waste.”

• This left states to decide what to do with the

millions of tons of coal ash generated

each year.

IN 2014 THE EPA ANNOUNCED CHANGES…
