Eyjafjallajokull Volcanic Ash: Can it Be Used as Substitute for Portland Cement?

Evironmental Council of the United States "Resolution 8-14 Regulation of Coal Ash"

The Resolution was revised to acknowledge EPA’s CCB rulemaking effort and states that “if U.S. EPA promulgates a federal regulatory program for state CCW waste management programs, the regulations must be developed under RCRA Subtitle D rather than RCRA Subtitle C.” In addition to opposing hazardous waste regulations as unnecessary to ensure the proposed management of CCBs, ECOS confirms its position that “designating CCW a hazardous waste under RCRA Subtitle C could create stigma and liability concerns that could impact the beneficial use of CCW.”\
