On March 11, 2014, a consent decree was entered between the United States, the Louisiana Department of Environmental Quality (LDEQ), and Cabot Corporation. Cabot Corporation, the second largest carbon black manufacturer in the United States, has agreed to pay a $975,000 civil penalty and spend an estimated $84 million on state of the art technology to control harmful air pollution, resolving alleged violations of the New Source Review (NSR) provisions of the Clean Air Act (CAA) at its three facilities in the towns of Franklin and Ville Platte, La. and Pampa, Texas. For each facility, the settlement requires that Cabot optimize existing controls for particulate matter or soot, operate an early warning detection system that will alert facility operators to any particulate matter releases, and comply with a plan to control fugitive emissions which result from leaks or unintended releases of gases. To address nitrogen oxide (NOx) pollution, Cabot must install selective catalytic reduction technology to significantly reduce emissions, install continuous monitoring, and comply with stringent limits. At the two larger facilities in Louisiana, Cabot must address sulfur dioxide (SO2) pollution by installing wet gas scrubbers to control emissions, install continuous monitoring, and comply with stringent emissions limits. In addition, the Texas facility is required to comply with a limit on the amount of sulfur in feedstock which is the lowest for any carbon black plant in the United
