The El Ceibillo development project is an advanced stage, steam geothermal prospect within a 100km2 energy rights concession located 8.5 miles from Guatemala City, the capital city of Guatemala.

The license is based on the Environmental Impact Assessment study that was submitted in December 2012, describing the initial design of the 25MW facility, and requires the submittal of final design specifications for review by MARN prior to starting physical construction of the plant.

Further, the license requires compliance with all legal and regulatory requirements under Guatemalan law, submittal of an air quality monitoring plan, and that final design comply with the strict guidelines for noise, dust and hydrogen sulfide emissions.

Prior to issuance of the license, an environmental bond of approximately $45,000 was posted with the Ministry of Environment and Natural Resources.

U.S. Geothermal CEO Dennis Gilles said, "The issuance of this license is an important step in our development plans for the El Ceibillo Project.

"While we are still working on developing the geothermal reservoir, having the environmental license in hand will allow us to move the project forward within an efficient time frame."
