On April 13, 2026, the Commission set a May 4, 2026, intervention deadline for this case.

timely filed "must state a substantial reason for delay." IDAPA 31.01.01.073. "The Commission
may deny or conditionally grant petitions to intervene that are not timely filed for failure to state
good cause for untimely filing to prevent disruption, prejudice to existing parties, or undue
broadening of the issues, or for other reasons." Id. Also, "Intervenors who do not file timely
petitions are bound by orders and notices earlier entered as a condition of granting the untimely
petition."Id.

existing parties, or unduly broaden the issues in this proceeding. Id. at 3.
