Upper Las Vegas Wash Conservation Transfer Area Supplemental Environmental Impact Statement
Welcome to the Upper Las Vegas Wash Conservation Transfer Area Supplemental Environmental Impact Statement Website.
The Bureau of Land Management (BLM) Las Vegas Field Office is analyzing possible boundary adjustments to the Upper Las Vegas Wash Conservation Transfer Area (CTA) referenced in the 2004 Las Vegas Valley Disposal Boundary Environmental Impact Statement (EIS) and Record of Decision. Because of the significance of paleontological, botanical, and cultural resources present in the Conservation Transfer Area and the need for additional public input, BLM is preparing a Supplemental Environmental Impact Statement (SEIS). The SEIS will supplement the 2004 Record of Decision for the Las Vegas Valley Disposal Boundary EIS. This SEIS is needed to protect sensitive resources, including fossils, cultural resources, and endemic plants, on public lands available for disposal within the CTA study area, allowing for compatible uses, in accordance with other applicable laws. One important consideration in the SEIS will be determining which entity or entities (federal or nonfederal) may manage all or portions of the CTA. 
Preparation of the SEIS will include six stages:
Notice of Intent
The process begins with a Notice of Intent published in the Federal Register. The Notice of Intent for the SEIS was published on July 6, 2007.
Scoping Period
The purpose of scoping is to provide an opportunity for the public to learn about the project and to share any concerns or comments they may have. Input from the public scoping process will be used to help BLM identify a range of alternatives that should be considered in the SEIS, as well as to identify issues and concerns regarding the various alternatives.  In addition, the scoping process helps identify any issues that are not considered significant and can thereby be eliminated from detailed analysis in the EIS. The list of stakeholders and other interested parties is also updated and generally expanded during the scoping process.
The scoping period for the SEIS began on July 6, 2007 and continues through August 20, 2007.
Draft SEIS
The BLM prepares a Draft SEIS and makes it available to the public. This document generally includes the following:
  • Summary
  • Purpose of and need for action
  • Alternatives, including proposed actions
  • Affected environment
  • Environmental consequences
  • Mitigation measures to minimize impacts 
The Draft SEIS is distributed to stakeholders and other interested parties for review. The availability of the Draft SEIS is announced in the Federal Register through a Notice of Availability (NOA).
Draft SEIS Public Comment Period
The publication of the NOA in the Federal Register begins the 45-day public comment period for the SEIS. The notice includes specific information about the public comment period, including a timeframe, notes public meetings, and information about how comments may be submitted. Public participation associated with the Draft SEIS is administered by the BLM.
Final EIS
After the public comment period, a Final SEIS is prepared. This document includes descriptions of public comments and indicates how the comments were addressed in the Final SEIS. An NOA is posted in the Federal Register announcing the completion and availability of the Final SEIS. The Final SEIS is distributed to stakeholders and other interested parties.
Record of Decision
No sooner than 30 days after the Final SEIS is published, a Record of Decision describing the BLM's decision regarding the proposed action is signed.
