WASHINGTON, D.C. - A District of Columbia Circuit U.S. Court of Appeals panel on July 8 denied CTS Corp.'s petition challenging the U.S. Environmental Protection Agency's decision in 2011 to add a site in Asheville, N.C. that was formerly owned by a subsidiary of the company to the National Priorities List, finding that the agency's decision was not arbitrary and capricious (CTS Corporation v. U.S. Environmental Protection Agency, No. 12-1256, D.C. Cir.; 2014 U.S. App. LEXIS 12804).
