The Latest On: Coal Ash Regulations
The Environmental Protection Agency endorsed mixing coal ash into cement as an alternative to storing it in ponds, claiming it makes cement stronger and emits less emissions than other cement refining techniques. Mixing coal ash into cement could also prevent toxins such as arsenic, lead and mercury from contaminating groundwater. “I think characterizing it as a ‘win’ would be accurate. If you’re going to make coal ash in the first place, locking it up in concrete is preferable to a lot of the other ways we use or dispose of coal ash,” said Earthjustice attorney Lisa Evans.
