Petroleum Industry Leader Outsources Nationwide Site Closure Initiative to ENSR

CAMARILLO, Calif., Oct. 7 -- ENSR International, a worldwide environmental consulting firm, has been awarded a nationwide Portfolio Reduction Project for Unocal Corporation. In the major three-year contract, Unocal is outsourcing to ENSR the regulatory closure of over 275 sites that used, handled or distributed petroleum, chemicals or agricultural products. Sites include gas stations, truck stops and bulk terminals in 35 states.

The portfolio reduction project, already underway, enables Unocal to transition to ENSR the environmental assessment, management, remediation and site closure of this portfolio as part of its program to manage costs. ENSR's solution presented the best combination of broad environmental and technical expertise and project management experience to meet the business and cost management goals closing 275 sites.

The high priority project will use ENSR experts in remediation, hydrogeology, risk assessment and air permitting, monitoring and other disciplines to support its nationwide network of project managers leading site closure. ENSR is utilizing project-specific tools such as costing models, site templates, checklists, extranets, and continuous improvement strategies to help transfer lessons learned over the course of the closures.

Unocal, a charter member of ENSR's highly successful key client program, has awarded ENSR environmental projects on 3 continents and in 33 US states over the past 10 years. The new contract complements ENSR's extensive exploration and production remediation work for Unocal's other business units.

Bob Weber, ENSR President and CEO stated: "This is an important win for ENSR because we have geared our company to providing just this kind of comprehensive partnering support to our major industrial clients. Outsourcing like this helps us provide cost-effective environmental solutions for Unocal through our integrated site closure approach, remediation system evaluations, and innovative technology led by our expert project managers."
