Uranium Mining Districts

One of 4 areas BLM's Utah office names Uranium Mining Districts; this one is 1,939 acres. All of them. BLM found a historic value here, and its plan calls for special management. BLM's records place at least 56 active mining claims (and 20 more BLM lists as Filed) and 1 right of way inside the line today, and a grazing allotment covers part of it. It covers 1,939 acres and was designated October 31, 2008, in the Price Field Office RMP. In the plan's name, RMP stands for resource management plan.

The proposed rule

A proposed rule, RIN 1004-AF53, would change how BLM drafts every land use plan, and how it designates ACECs like Uranium Mining Districts. The comment window hasn't opened: the proposed rule wasn't in the Federal Register at our last check. The Watch sends one email the day it prints.

The rule's abstract

The purpose of this rulemaking is to establish in regulations an updated process for the approval of the development, revision, amendment, and maintenance of land use plans, as provided for by the Federal Land Policy and Management Act of 1976, for public lands administered by the Bureau of Land Management (BLM). Additionally, this rulemaking will provide clarification of the process the BLM uses for designating Areas of Critical Environmental Concern.Unified Agenda entry for RIN 1004-AF53, Publication ID 2026, reginfo.gov (OMB OIRA), read Oct 18, 2026
