Boston-based 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, the Department of Justice and the U.S. Environmental Protection Agency (EPA) announced today. This agreement is the first to result from a national enforcement initiative aimed at bringing carbon black manufacturers into compliance with the CAA’s NSR provisions.
