Project Description

NOTE: To comment during the comment period, please click the "Participate Now" button at the top of the page. The comment period ends July 29 at midnight, Mountain daylight time (UTC-6).

The Secretary of the Interior proposes to revoke the withdrawal of up to approximately 336,425 acres of public lands located within a radius of approximately 10 miles surrounding Chaco Culture National Historical Park (CCNHP) in San Juan County, northwestern New Mexico. Public Land Order (PLO) No. 7923 established a withdrawal in 2023 which withdrew these public lands from location and entry under the United States mining laws and from leasing under the mineral leasing laws, subject to valid existing rights, for a 20-year term.
 
Revocation of the PLO No. 7923 withdrawal would restore discretion over mineral leasing to the Bureau of Land Management and would re-open that public land to location and entry under the United States mining laws. It is important to note that the land in question was not withdrawn from disposal under the Materials Act of 1947, which largely concerns the sale of common-variety sand, gravel, and other such commodities from federal land.

The BLM will prepare an environmental assessment that will analyze the following alternatives, which may be refined based on input received during the scoping process:
 
No Action Alternative: 10-mile buffer withdrawal remains in effect
Public Land Order No. 7923 would remain in effect, keeping approximately 336,404 acres closed to new mineral leasing and mineral entry for 20 years, subject to valid existing rights.
 
Alternative 1 (Proposed Action): Revoke the withdrawal in full   
The Secretary or appropriate Secretarial official would revoke the public land order in full, reopening all 336,404 acres to mineral leasing and to location and entry under the U.S. mining laws. Management of mineral resources would conform to the provisions of the 2003 Farmington Resource Management Plan.
 
Alternative 2: Revoke the withdrawal to allow leasing and mining beyond a 5-mile buffer
The Secretary or appropriate Secretarial official would revoke the public land order in part, reopening public lands beyond a 5-mile buffer around Chaco Culture National Historical Park to both mineral leasing and location and entry under the U.S. mining laws.
 
A scoping period was held, intended to gather input on the scope of the environmental analysis and potential issues to be considered. A subsequent comment period on a Draft EA follows.

What's New

How to Participate in the Draft EA Comment Period: Comments are welcome from U.S. citizens. To leave a comment on the public draft Environmental Assessment, click the blue Participate Now button at the top of the page and enter your written comments in English.

The comment period ends July 29 at midnight, Mountain daylight time (UTC-6).

How to Provide a Substantive Comment: The most effective public comments will contain substantive new facts, analysis, and/or sources that bring new information for the agency to consider. BLM uses public comments to improve the agency's analysis, correct errors, and identify reasonable alternatives. Public comments are not a voting process: agency decisions do not rely upon the number of comments for or against a particular project. Instead, decisions are based on law, regulation, policy, and the analysis of environmental effects.

Effective comments will provide information the agency can act on, such as:

Missing data or corrections
Local knowledge of resources and uses
Specific analytical gaps
Reasonable alternatives or mitigation
Literature or references the agency can cite (e.g. studies, inventories, cultural resource documentation)
