In response to recent calls for new federal regulation of coal ash, the Environmental
Protection Agency (EPA) has begun gathering data on coal ash management practices
as a first step toward new ash management regulations for coal-fired utilities.
Such regulations could include new structural stability requirements for ash
ponds, as well as stricter ash management requirements.
EPA has twice determined that coal ash and materials from air pollution control
equipment (collectively called Coal Combustion Products - CCPs) should not
be considered – or regulated – as a hazardous waste. Most recently,
in 2000 EPA published a final regulatory determination that fossil fuel combustion
wastes, including CCPs, “do not warrant regulation as hazardous waste
under RCRA [Resource Conservation and Recovery Act],” and that “the
regulatory infrastructure is generally in place at the state level to ensure
adequate management of these wastes.”
“Nothing about coal ash has changed since that ruling,” points
out NRECA’s vice-president for environmental affairs Kirk Johnson. “NRECA
believes coal ash is appropriately regulated, and opposes efforts to reclassify
coal ash as hazardous waste.”
Classifying CCPs as hazardous wastes would effectively limit recycling efforts
and commercial use of the material. Manufacturers currently use CCPs for a
variety of purposes, including the production of gypsum (wallboard) and concrete.
CCPs are also safely used in highway and building construction applications
and as fill material. Several cooperatives have used coal ash in the construction
of new cooperative buildings. Some bowling balls are made using coal ash.
By using CCPs these manufacturers reduce their need for raw materials. And
by displacing raw materials, using coal CCPs also lowers the amount of carbon
dioxide that would have been emitted in extracting and processing.
Within the current regulatory framework, states are responsible regulation
of CCPs. In 2000, EPA determined that the regulatory infrastructure is generally
in place at the state level to ensure adequate management of coal ash. Since
that time, state regulations have become even more stringent and in 2008 state
regulatory agencies reiterated the position that the states – not the
federal government – should be responsible for the regulation of coal
ash as a non-hazardous waste. State programs can be tailored to best take into
account site-specific considerations, as they are able to account for local
climate, geology, and hydrology.
The recent TVA spill proves accidents can happen; coal ash does need to be
properly managed. Cooperatives are careful in their management of coal ash
surface impoundments and their record of handling this substance for more than
30 years without incident is a testament to the adequacy of current safeguards.
“As stakeholders in their local communities, cooperatives consider
themselves good stewards of the environment. We are confident that when EPA
reviews cooperative management practices, their analysts will concur,” Johnson
says.
