The state Senate has unanimously approved a bill to bolster air monitoring in Litchfield County.  The measure, backed by Danbury Senator Julie Kushner and Kent Representative Maria Horn, was introduced in response to the Cricket Valley Energy Center.  The facility is set to open next year in nearby Dover New York.  The Connecticut will requires the Department of Energy and Environmental Protection to offer air monitoring assistance to towns that purchase, lease or is provided the use of air monitoring equipment to establish an air quality baseline.  The state previously declined to expand its air monitoring network, but local municipalities have taken action.  The bill now goes to the House.
