SUPPLEMENTARY INFORMATION:

Introduction

    The United States Department of the Interior (DOI), the U.S. Fish 
and Wildlife Service, and the National Park Service, in coordination 
with the U.S. Department of Agriculture (USDA), the Forest Service (the 
agencies) publish this notice to announce the availability of a draft 
addendum to the Federal Land Managers' Air Quality Related Values Work 
Group's Phase 1 Report, which the agencies last revised in 2010 (FLAG 
2010 report). We are proposing an addendum to add a contextual 
consideration provision to the FLAG 2010 report concerning the FLM's 
analysis of temporary emissions for overall low-emitting facilities. We 
invite comments and information from the public and local, State, 
Tribal, and Federal agencies.

Background

    FLAG was formed by the Department of the Interior's National Park 
Service and U.S. Fish and Wildlife Service, and the U.S. Department of 
Agriculture's Forest Service, (1) to develop a more consistent and 
objective approach for these agencies' Federal land managers (FLMs) to 
evaluate air pollution effects on their air quality related values 
(AQRVs) in Federal class I areas, as defined by the Clean Air Act, and 
(2) to provide State permitting authorities and potential permit 
applicants consistency on how to assess the impacts of new and existing 
sources on AQRVs.
    The FLAG effort focuses on the effects of the air pollutants that 
could affect the health and status of resources in areas managed by the 
agencies, primarily such pollutants as ozone, particulate matter, 
nitrogen dioxide, sulfur dioxide, nitrates, and sulfates.
    The initial FLAG Phase 1 Report was published in 2000. On October 
27, 2010, the National Park Service, in cooperation with the U.S. Fish 
and Wildlife Service and the Forest Service, published a revised FLAG 
report (75 FR 66125). This notice announces the availability of a draft 
addendum to the FLAG 2010 revision to add a contextual consideration to 
FLAG 2010 report concerning the FLM's analysis of temporary emissions 
for overall low-emitting facilities. The draft addendum would not 
change the FLM's role or affirmative responsibilities under the Clean 
Air Act. The draft addendum seeks to assist FLAG 2010 report users by 
describing how the FLMs will consider temporary emission for overall 
low-emitting facilities as it analyzes effects to AQRVs in Federal 
class I areas as part of the FLMs responsibilities under the Clean Air 
Act.
    Authority: Clean Air Act of 1970, as amended (42 U.S.C. 7401 et 
seq.).

Assistant Secretary for Fish and Wildlife and Parks.
