"Sempra Fight". In 1998, Sempra Energy submitted a proposal to the Connecticut Siting Council to construct a power plant approximately south of Washington in New Milford. The plant was to emit 443 tons of pollutants per year, many of which would have projected toward Washington, owing to the region's prevailing wind patterns and complex terrain. The Washington Environmental Council hired environmental consultants, who demonstrated that the plan would be particularly harmful to New Preston and Lake Waramaug. The council became an intervenor in the proceedings and generated scientific evidence that was cited by the Siting Council when it unanimously rejected the permit application in 1999.
