OSTI ID:20002255
The FLAG (Federal Land Manager's AQRV WorkGroup) Ozone Subgroup was organized to compile information known about response of vegetation to ozone in federally managed parks, forests, and wildlife refuges; to document areas of agreement among federal agencies regarding identification of ozone sensitive Air Quality Related Values (AQRVs); and standardize agency responses to New Source Review (NSR) permit applications. Subgroup members included air resource managers and ozone effects scientists from several agencies that manage federal lands. The subgroup identified sensitive AQRV receptors, determined information needed to evaluate permit applications under the NSR process, determined the form of an ozone parameter to use to relate plant response to ambient ozone, and agreed on specific definitions for vegetation injury and damage from ozone. The subgroup developed specific protocols for federal agencies to follow in response to NSR permit applications. These protocols were based on (1) ambient levels of ozone as measured by the W126 ozone metric and the number of peak ozone concentrations $100 ppb (N100), and (2) the presence or absence of ozone sensitive plant species and ozone-induced damage to vegetation.
