Comment submitted by National Ready Mixed Concrete Association (NRMCA)

Summary: The National Ready Mixed Concrete Association (NRMCA) supports the proposed rule to reduce regulatory burdens on coal combustion residuals (CCR), specifically fly ash, to ensure its continued use in the ready mixed concrete industry. They urge the EPA to go further by explicitly exempting fly ash used in concrete production from federal regulations and ensuring that new storage definitions do not inadvertently capture manufacturing facilities.
