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:
