Merrimack Station
{{#badges: CoalSwarm| Climate change}} Merrimack Station is a coal-fired power station owned and operated by Public Service Company of New Hampshire (PSCNH), a subsidiary of Northeast Utilities, near Bow, New Hampshire. One unit of the plant was built in 1960, the other in 1968. In 2008, the future of the plant became the subject of controversy when PSCNH revealed in August that the projected cost of new mercury-control scrubbers had increased from $250 million to $457 million.[1] The scrubbers would reduce mercury emissions by 80 percent.[1]

Reducing Air Pollution Emissions
In 2006, Governor Lynch signed legislation that requires PSNH to reduce mercury by a scrubber system by 2013.[3] The Public Service Company of New Hampshire was required to file an application for a Temporary Permit for a flue gas desulphurization system (FGD) by June 8, 2007.[4] On June 6, 2008, PSNH filed their application for the Temporary Permit; additional information was added to their application on September 4, 2007, April 17, 2008, October 24, 2008, November 21, 2008, and December 11, 2008.[4]
On December 11, 2008, an announcement of a public hearing and request for public comments was published in the "Concord Monitor".[4] The same announcement was published in the New Hampshire "Union Leader".[4] The public hearing was held on January 15, 2009 and public comments were accepted until January 23, 2009.[4]
An ad hoc group of 24 businesses, led by Stonyfield Farms CEO Gary Hirshberg and including inventor Dean Kammen and Timberland President Jeffrey Schwartz, petitioned the state to reconsider the scrubbers.[1] The group adopted the name 21st Century New Hampshire.
Energy analyst Symbiotic Strategies LLC made an assessment of the future costs to comply with increased greenhouse gas, mercury and other requirements. It came up with an additional cost of between $864 million and $2.5 billion. The impact on ratepayers would be three to six times higher than PSNH's estimated increase of one-third of a cent per kWh for the scrubber project, according to the analysis.[1]
On March 13, 2009, the New Hampshire Senate Energy, Environment and Economic Development Committee held a hearing on SB-152, the "Mercury Reduction and Ratepayer Protection Act." The bill that would order a review of the scrubbers.[1] About 150 trade union members attended the hearing wearing T-Shirts that said “Don’t scrub my job.”[5] Environmentalists supported the study, as did Hirschberg's businesses coalition. Several speakers said Merrimack Station should be closed. Representatitives of the Concord and Nashua chambers of commerce testified against the bill, as did labor groups and officials from Bow, Hooksett and Manchester.[5]
