Locus Wins Geothermal, Inc. Facility Closure Project

SAN FRANCISCO, CALIFORNIA, 6 October 2003 — Locus Technologies (Locus), a leader in environmental consulting and construction services, announced today that it has been awarded a contract to provide design-build services for closure of the Geothermal Inc. (GI) Facility Closure Project. The contract will be performed over a three-year period.

The GI Facility is an inactive disposal facility located near Middletown, Lake County, California. The facility includes seven surface impoundments and two disposal trenches that accepted liquid and solid waste from the geothermal energy exploration and production fields. The non-hazardous waste is a mixture of geothermal well drilling fluids and other geothermal power plant wastes. The three-year facility closure will consist of completing the final engineering design and necessary closure documents, obtaining necessary permits, and performing closure construction activities. The waste will be solidified and capped with a low-permeability engineered closure cover system consisting of a geomembrane barrier layer, geocomposite drainage layer, and clean vegetated soil cover. Pond liquids will be treated using reverse-osmosis and thin-film solar evaporation technologies. In addition, phytoremediation will be used to lower groundwater to achieve the required separation from the waste. Disposal trenches will be excavated, solidified, and consolidated into the closure cells. When implemented, closure will assure the long-term protection of human health and environment.

GI’s owners and operators abandoned the site in 1986 and filed for bankruptcy before posting their required closure bond. Consequently, 17 companies that disposed of material at GI are financing the closure. A Site Management Committee with top environmental staff from five of the companies has been planning the closure. Under the contract, Locus will provide turnkey professional consulting, engineering, and construction services for remedial
construction.

“We are very pleased to be selected by the GI Site Management Committee to close the GI site. This further demonstrates Locus’s ability to provide turnkey consulting and construction services to our clients on complex, multidisciplinary soil and groundwater sites. We will be working closely with the Cooperating Entities, other specialty consultants, regulators, and the public to implement the remedy and restore the site,” said Dr. Neno
Duplancic, President and CEO of Locus Technologies.
