LOWELL, MA--(Marketwire - September 16, 2010) -  TRC Companies, Inc. (NYSE: TRR) today announced that it has been awarded a contract by the United States Section of the International Boundary and Water Commission (USIBWC) to prepare a river restoration implementation plan for a 105-mile portion of the Rio Grande Canalization Flood Control Project upstream of El Paso, Texas. The project will facilitate the restoration of sites that are currently considered low quality monocultures of non-native salt cedar vegetation in order to improve riparian functions and, in particular, provide habitat and ecological diversity for many species. TRC has supported multiple USIBWC projects over the past two years.

"TRC is proud to continue our relationship with the USIBWC," said Chris Vincze, Chairman and Chief Executive Officer. "As a company, we are committed to solving our nation's environmental challenges. We embrace USIBWC's goal of improving the Rio Grande ecosystem and are dedicated to delivering results they can rely on."

TRC will conduct soil and archaeological surveys, survey endangered bird species in the area, and prepare a restoration implementation plan to produce enhanced aquatic diversity and improve natural river processes and the area as a habitat for wildlife.
