Salem Harbor Plant Back On-Line

Dominion's Salem Harbor Station in Salem, MA brought its Unit 2 boiler back on-line late last Friday night. The plant had been shut down since November 6, 2007, when a tragic steam explosion killed three plant workers.

The Salem Harbor Station uses CleanAir's MET-80 sorbent trap systems to monitor mercury emissions from three of its four boilers. Under Massachusetts regulations, coal-fired utilities in the state have been required to continuously monitor mercury emissions since the beginning of 2008.

Massachusetts is one of the first states to implement requirements for mercury monitoring at utilities. As such, Salem Harbor's three MET-80 systems are some of the first mercury monitoring systems of any type in the nation to be officially certified for regulatory reporting purposes. All three systems passed their Relative Accuracy Test Audit (RATA) certification tests last October.
