AIR QUALITY for the Interagency Wilderness Fire Resource Advisor • Discussion Topics: • Very Brief Overview of Air Pollution • Define Class I Areas and the National Goal for Visibility • Clean Air Act direction to EPA • Regional Haze and IMPROVE monitoring • Clean Air Act direction to Federal Land Managers • Agency Policies • Group Discussion: What All This Means for a WFRA. • Strategies / Guidelines? 2011 SOUTHERN AREA ADVANCED FIRE AND AVIATION ACADEMY
National Ambient Air Quality Standards Change in Air Quality Standards for Ground-Level Ozone On March 12, 2008, the U.S. Environmental Protection Agency (EPA) changed the primary and secondary air quality standards for ground-level ozone. The new standard was changed from 0.08 parts per million (ppm) to 0.075 ppm. EPA is in the process of evaluating the need to change this again. Until that decision is issued (2011?), the States will use the 0.08 ppm standard. • NAAQS

CLEAN AIR ACT, as amended 1977 • Visibility protection for Class I areas • Congress declared a national goal of preventing any future, and remedying any existing, impairment of visibility in mandatory Class I federal areas caused by manmade air pollution. 2011 SOUTHERN AREA ADVANCED FIRE AND AVIATION ACADEMY

CLEAN AIR ACT, as amended 1977 • Visibility protection for Class I areas • The federal land manager shall have an affirmative responsibility to protect the air quality related values (including visibility) within Class I areas. 2011 SOUTHERN AREA ADVANCED FIRE AND AVIATION ACADEMY
Prevention of Significant Deterioration (PSD) • FLM responsibilities include: • the review of air quality permit applications from proposed new or modified major pollution sources near Class I areas. • If the FLM determines that emissions from a proposed source will cause or contribute to adverse impacts on the air quality related values (AQRVs) of a Class I area, the permitting authority, typically the State, can deny the permit.
FEDERAL AGENCY POLICY • Allow fire its natural role in wilderness areas and fire-dependent ecosystems. • Integrate air quality considerations into fire management decisions. • Reduce the impacts of smoke from wildland fires on visibility in Class I wilderness, while understanding and promoting the need to re-introduce the natural role of fire in the wilderness ecosystems. • Provide guidance in fire management plans for responding to natural and human-caused wildland fires and address the effects of fire management decisions on wilderness resources and character, air quality, smoke management, water quality, and other pertinent natural and cultural resource management objectives. • Recognize and consider wilderness values (e.g., air quality and air quality related values) when responding to wildfires in wilderness. Mitigate potential negative or unacceptable impacts of smoke on air quality in such areas as Class I airsheds. • Manage smoke from management ignited prescribed fires occurring in or adjacent to Class I wilderness areas in a manner that causes the least impact on air quality related values
CLASS DISCUSSION: WFRA STRATEGIES MATERIALS / RESOURCES: STRATEGIES / GUIDELINES: • Incorporate air quality effects (incl. visibility) in wildfire response strategies? • “Burn Outs” planned on good dispersion day? • Others? • Wilderness Mgmt Plan • Wilderness Air Quality Values Monitoring Plan • Fire Mgmt Plan • Forest Plan • State Implementation Plan (SIP) • Local Air Quality Specialist Contact Info • Smoke Dispersion Forecast
