# 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.*).                

Shannon A. Estenoz,

Assistant Secretary for Fish and Wildlife and Parks.
