On behalf of the Association of State and Territorial Solid Waste Management Officials (ASTSWMO), I would like to thank you for the time you and your staff have invested in considering our concerns on EPA’s upcoming proposal for regulations promulgated under §108(b) of CERCLA. We really appreciate the many updates, meetings, and conference calls where you have provided useful information and listened to our concerns and the concerns of State hardrock mining regulators. We will seek to continue these cooperative efforts as EPA develops the first rule under CERCLA §108(b) to address hardrock mining sites.
