Selling the Environmental Business Unit to TRC allows RMT to focus solely on providing siting, permitting, engineering, and construction services to the renewable energy infrastructure market, including wind, solar, and geothermal energy. RMT will also continue to target facility siting and engineering work.

"This decision refines RMT's strategic path forward," said RMT President Steve Johannsen. "The Environmental Business Unit has been the foundation of the RMT operation for much of our 34-year history. These core competencies have helped to establish a place for RMT in the renewable energy market. However, by maintaining a singular focus on building better, more reliable renewable energy facilities, we believe RMT will be better able to focus the growth of our business, while providing quality service to our clients."

"TRC has a strong working knowledge of RMT's environmental service lines and has committed to investing in their growth," Johannsen continued. "The company has the resources to ensure that our environmental professionals get the personal and professional opportunities they deserve and that RMT's long-term environmental clients continue to receive excellent service. This sale should open up more opportunities for growth on both fronts."

Over the past decade, RMT has provided construction, engineering, design, and development services for over 3,800 MW of renewable energy across the U.S. In 2011, the company has been selected to design and build ten wind energy projects totaling nearly 1,100 MW and eight utility-scale solar photovoltaic (PV) projects totaling 55 MWdc. These projects bring RMT's total renewable energy portfolio to over 4,900 MW.
