Notice of Availability of the Las Vegas Metroplex Project Written 
Re-Evaluation/Record of Decision for Changes to the Final Environmental 
Assessment Designs

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation.

ACTION: Notice of availability of the Written Re-evaluation/Record of 
Decision (WR/ROD).

-----------------------------------------------------------------------

SUMMARY: The FAA is issuing this notice to advise the public that it 
has issued a WR/ROD for changes to the Las Vegas Metroplex Project 
Final Environmental Assessment (EA) Design for five flight procedures.

FOR FURTHER INFORMATION CONTACT: Emily Sturnfield, Operations Support 
Group, Northwest Mountain Regional Office, Federal Aviation 
Administration, 2200 216th Street, Des Moines, Washington 98198; 
telephone: (206) 231-2415.

SUPPLEMENTARY INFORMATION: On July 17, 2020, the FAA published in the 
Federal Register notice of the availability of a Finding of No 
Significant Impact and Record of Decision (FONSI/ROD) for the Las Vegas 
Metroplex (LAS Metroplex) Final EA. The designs for five proposed 
procedures analyzed in the Final EA and approved for implementation in 
the FONSI/ROD require changes to comply with FAA safety criteria. This 
notice refers to these changes as the ``Design Changes.''
    Four of the Design Changes are to the designs of procedures at 
McCarran International Airport (KLAS): (1) HOOVER SEVEN Standard 
Instrument Departure (SID), (2) Area Navigation (RNAV) (Required 
Navigation Performance [RNP]) Z Runway (RWY) 19R approach, (3) RNAV 
(Global Positioning System [GPS]) Y RWY 19R approach, and (4) RNAV 
(RNP) Z RWY

19L approach. The fifth change is to the design of a procedure at 
nearby Henderson Executive Airport (KHND), the GAMES Standard Terminal 
Arrival Route (STAR).
    To determine whether the Design Changes require supplementation of 
the Final EA, the FAA has analyzed the potential environmental effects 
from the Design Changes, consistent with FAA Order 1050.1F, Paragraph 
9-2.c.(1), to determine whether the changes to the Final EA Design 
would be ``substantial'' and ``relevant to environmental concerns,'' 
i.e., ``paint[s] a dramatically different picture of impacts compared 
to the description of impacts in the [Final] EA'' (id., Paragraph 9-3). 
The FAA's analysis and determination are documented in a WR/ROD dated 
December 21, 2020. The WR/ROD analyzes the same environmental impact 
categories analyzed in the Final EA.
    As documented in the WR/ROD, the FAA has determined that the Design 
Changes are not a substantial change in the FAA's proposed action, as 
analyzed in the Final EA for the Las Vegas Metroplex Project and 
approved in the FONSI/ROD, relevant to environmental concerns. The data 
and analyses contained in the Final EA and FONSI/ROD are still 
substantially valid and there are no significant new circumstances or 
information relevant to environmental concerns and bearing on the 
proposed action or its impacts. Accordingly, the WR/ROD also documents 
the FAA's decision not to prepare a supplement to the Final EA.
    The WR/ROD is publicly available at https://www.faa.gov/air_traffic/community_involvement/las/ and http://www.metroplexenvironmental.com/las_metroplex/las_docs.html.
