reports in the first quarter of 2022 and circulated the preliminary Supplemental Draft Envir onmental
Impact Statement (“SDEIS”) for cooperating agency review. The SDEIS is anticipated to be released for

Company petitioned to intervene in the administrative process on A ugust 12, 2022 to join IDEQ in
defending the permit and the record justifying its requirements.
