Administrative appeal dismissed.
A Connecticut Superior Court dismissed the environmental group Save the Sound and the Town of Brookfield’s administrative appeal of the Connecticut Department of Energy and Environmental Protection’s (CTDEEP’s) denial of their petitions to intervene in Iroquois Gas Transmission System, L.P.’s (Iroquois’s) application to expand its natural gas compressor station in Brookfield. Save the Sound and the Town’s petitions to intervene alleged, among other things, that construction and operation of two additional turbines would increase greenhouse gas emissions and impede Connecticut’s ability to meet the emissions limits established by the Global Warming Solutions Act. The court agreed with CTDEEP and Iroquois that denials of petitions to intervene are not appealable final orders and found that dismissing the administrative appeal would not deprive Save the Sound and the Town of an adequate remedy since they would be able to appeal when CTDEEP issues an order on Iroquois’s application.
