The U.S. Environmental Protection Agency (EPA) issued a state implementation plan (SIP) call action to 36 states directing them to correct specific startup, shutdown, and malfunction provisions in their SIPs to ensure they are fully consistent with the Clean Air Act (CAA). The action comes in response to a petition for rulemaking filed by the […]

An emergency action proposed by Maryland regulators on Friday will require 14 coal-fired units in the state to minimize nitrogen oxide (NOx) emissions every day during the 2015 summer ozone season, starting as soon as May 1.  The rule submitted on April 17 by the Maryland Department of the Environment (MDE) to the Joint Committee […]

 While fuel switching may be the easiest option for hitting the 2020 and 2030 goals set by the Environmental Protection Agency’s (EPA’s) proposed Clean Power Plan, it may impede reaching longer-term climate targets said experts at an April 8 symposium hosted by the Central Texas Association for Energy Economics and the Energy Institute at the […]
