Yesterday, the US Environmental Protection Agency (EPA) granted a petition by the New Jersey Department of Environmental Protection (NJDEP) to limit sulfur dioxide (SO2) emissions from a Pennsylvania power plant. Emissions from the coal-fired power plant, Portland Generating Station in Northampton County, have adversely impacted air quality in four northwest NJ counties: Warren, Sussex, Morris, and Hunterdon. The EPA has ordered the plant to reduce its SO2 emissions by 81 percent over a three year period.
