The Idaho Department of Environmental Quality (DEQ) is seeking comment on draft reuse permit renewal (I-210-03) for Raft River Energy 1, LLC.
Raft River Energy 1, LLC owns and operates a binary cycle geothermal power plant in Malta, Idaho that generates industrial wastewater as part of its operations. Raft River Energy 1, LLC is proposing to renew their recycled water reuse permit to beneficially use approximately 100 million gallons per year of industrial recycled water for land application on two management units and a rapid infiltration basin.
The draft reuse permit establishes monitoring requirements, limits on nutrient and hydraulic loading, and conditions established by DEQ to protect public health and the environment. As part of the permitting process, the facility was also required to show that its operation would not cause public health or environmental concerns.
Written comments on the draft permit will be accepted through June 18, at 5 p.m. mountain time. The draft permit and staff analysis are available for public review at DEQ’s State Office (1410 N. Hilton St., Boise, ID 83706) and below under related documents.
