The Department of Public Health and Environment proposed to amend 6 Colo. Code Regs. §1007.3, Hazardous Waste. Changes would remove the permit modification provisions for EPA Performance Track member facilities that currently exist in §100.63 and Appendix I to §100.63. There will be a hearing on November 16, 2010. http://www.sos.state.co.us/CCR/Upload/NoticeOfRulemaking/ProposedRuleAttach2010-00941.RTF.
