Accepting comments from January 22, 2025, through February 12, 2025.
BOISE – The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft water quality certification for the Farmway Road and Ustick Road roundabout project.
The proposed project would include the construction of additional driving lanes at the intersection of Farmway Road and Ustick Road. This would realign the Phyllis Canal to accommodate the widening of the road and replace the culvert on Bardsley Gulch Drain.
Based upon review of the federal permit application, readily available water quality related materials, and certification request in accordance with 40 C.F.R. §§ 121.5 (b) and (c) and 121.7 (c), DEQ, certifies that if the permittee complies with the terms and conditions imposed by the federal permit and the conditions set forth in this water quality certification, then it is reasonable for DEQ to conclude that the activity will comply with water quality requirements, including applicable requirements of the Clean Water Act §§ 301, 302, 303, 306, and 307, Idaho’s “Water Quality Standards” (IDAPA 58.01.02), and other appropriate water quality requirements of state law.

DEQ seeks comment on draft cyanidation permit for Perpetua Resources Idaho, Inc.
Accepting comments from December 31, 2024, through March 1, 2025
The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft cyanidation permit for the Stibnite Gold Project (SGP).
In accordance with the “Rules for Ore Processing by Cyanidation” (IDAPA 58.01.13), Perpetua Resources is requesting a permit to construct and operate a cyanidation facility as part of the SGP, a proposed gold mine located in Valley County, approximately 12 miles east of Yellow Pine, Idaho. The SGP is located on private and public lands within the Boise and Payette National Forests. Perpetua has 29,827 acres of mining claims comprised of both unpatented (28,477 acres) and patented (1,350 acres) claims. The mine is also located within the historical Stibnite Mining District, an area impacted by previous mining activities, including underground mine workings, rock dumps, tailings deposits, and open pits, including the Yellow Pine Pit.
Following review of the complete permit application, DEQ determined the application for the tailings storage facility and associated operation and maintenance plans is accurate and protective, in accordance with IDAPA 58.01.13.300.02. Therefore, DEQ prepared a draft cyanidation permit, which establishes the procedures and requirements to construct, operate, and close that component of the cyanidation facility. The draft permit would ensure that process water and process-contaminated water generated in ore processing utilizing cyanide are safely contained, controlled, and treated so that they do not interfere with the beneficial uses of waters and do not endanger public safety or the environment.
DEQ will host a public meeting on the draft permit on January 22, 2025, from 11 a.m. to 1 p.m. MDT. The meeting will be held virtually via Microsoft Teams.
The draft permit and fact sheet are available for review at DEQ’s State Office (1410 N. Hilton Street, Boise, Idaho), Boise Regional Office (1445 N. Orchard Street, Boise, Idaho) and on DEQ’s Public Comment Opportunities web page. Written comments will be accepted through March 1, 2025, at 5 p.m. MDT.

DEQ seeks comment on draft permit to construct for Itafos Conda, LLC
Accepting comments from January 22, 2025, through February 21, 2025.
The Idaho Department of Environmental Quality (DEQ) seeks comment on a draft permit to construct for Itafos Conda, LLC.
Itafos Conda produces phosphate-based fertilizers near Soda Springs, Idaho. Materials include the granular fertilizers monoammonium phosphate and ammonium phosphate sulfate, a liquid fertilizer called superphosphoric acid, merchant-grade phosphoric acid, and fluosilicic acid. Sulfuric acid is also used in the fertilizer production process and is manufactured at the facility and purchased from other sources.
The facility applied for a permit to construct a new ore beneficiation plant at the Soda Springs location. DEQ has determined that construction and operation according to the proposed permit will not cause or significantly contribute to a violation of any ambient air quality standard and will not injure or unreasonably affect human or
animal life or vegetation. DEQ has reviewed the application and completed an analysis of the information submitted by the applicant for the new beneficiation plant. Based on this analysis, DEQ proposes to issue the permit to construct.
The application materials are available for review on DEQ’s Public Comment Opportunities web page. Written comments will be accepted through February 21, 2025, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
