Combustion wastes are the solid and liquid waste left over from burning coal
and oil to make electricity - ash, sludge, boiler slag, mixed together with a
dozen or so smaller volume wastes. Every year, over 100 million tons of these
wastes are produced at nearly 600 coal and oil-fired power plants. Seventy-six
million tons are primarily disposed of at the power plant site in unlined and
unmonitored wastewater lagoons, landfills and mines. These disposal units are
operating under state rules that frequently are far less protective than rules
for household trash.
These wastes are highly toxic. They contain concentrated levels of
contaminants like arsenic, mercury, chromium and cadmium that can damage the
nervous systems and other organs, especially in children. Analysis performed for
EPA show that some of these pollutants will eventually migrate and contaminate
nearby groundwater. As an example, the excess cancer risks for children
drinking groundwater contaminated with arsenic from power plant wastes have been
found to be as high as one-in-one hundred - ten thousand times higher
than the Agency's own regulator goal of reducing cancer risks to less than
one-in-one million.
The toxicity is not just theoretical. We can point our finger to more than 60
places in the country where these wastes have degraded our public ground and
surface waters beyond any use - consumptive, agricultural, industrial, or
environmental. Fish consumption advisories in Texas and North Carolina have been
directly linked to coal combustion waste disposal. Studies in South Carolina
have documented multiple developmental, physiological and behavioral
abnormalities in the nearly 25 species of amphibians and reptiles inhabiting
wetlands associated with a coal ash disposal site. We know that this is just the
tip of the iceberg.
Current state rules are uneven and in some cases, non-existent. There are only a handful of states with adequately protective programs, and these protections do nothing to help the citizens of other states.
