Navajo Nation Integrated Weed Management Plan

The Bureau of Indian Affairs, Navajo Regional Office proposes to implement an integrated weed management program for noxious weeds within the Navajo Nation. The Proposed Action would authorize annual treatments of weed infestations up to 50,000 acres across the Navajo Nation. The various methods analyzed under an integrated weed treatment approach include manual, mechanical, cultural, chemical, and biological. Initial treatments will focus on areas that have weed inventories completed, including: roads, riparian areas, Navajo Agricultural Products Industry (NAPI) and Navajo Indian Irrigation Project (NIIP) lands, Navajo Tribal Utility Authority (NTUA) rights-of-ways, designated farm lands or croplands, designated rangeland or range management units (RMU), and Community Development Areas. This plan will encompass a 10-year period with a project review after five years. It is estimated that during the first five years of the project approximately 250,000 acres will be treated.

This draft Programmatic Environmental Impact Statement (PEIS) documents the analysis of the potential environmental consequences of implementing the Navajo Nation Integrated Weed Management Plan for the Navajo Trust Land and Navajo Indian Allotments within Coconino, Navajo, and Apache Counties in Arizona; McKinley, San Juan, Sandoval, and Cibola Counties in New Mexico; and San Juan County in Utah. The PEIS has been prepared in compliance with the National Environmental Policy Act (NEPA) guidelines as set by the Council of Environmental Quality in 40 CFR 1500-1508 and Indian Affairs National Environmental Policy Act (NEPA) Guidebook 59 IAM 3-H.  The alternatives evaluated in this Programmatic Environmental Impact Statement (PEIS) include: Alternative 1 is the No Action; Alternative 2 is the Proposed Action; and Alternative 3 had no biological control weed treatments.

The eight main chapters of this document describe proposed action; the purpose and need for the action; alternatives including the proposed action; affected environment; environmental consequences; cumulative impacts; adaptive management; consultation and coordination; and the list of preparers. The appendices include the Navajo Nation Integrated Weed Management Plan; Scoping Report; a list of the pesticide impaired waters of Arizona and New Mexico near the Navajo Nation; maps of the potential habitat on the Navajo Nation for all federally and tribally listed species; and the mitigation measures.
