The Department of Environmental Protection proposed to amend Regulations of Connecticut State Agencies §22a.174. Changes would eliminate three air management regulatory programs, including control of open burning; add compliance flexibility for large vehicle manufacturers; add exemptions for Stage II vapor controls; and revise fine particulate matter criteria. The deadline for comment is November 9, 2011. See http://www.ct.gov/dep/cwp/view.asp?A=2586&Q=486734.
