((4)) ** Condition class 2** The term “condition class 2”, with respect to an area of Federal land, means the condition class description developed by the Forest Service Rocky Mountain Research Station in the general technical report entitled “Development of Coarse-Scale Spatial Data for Wildland Fire and Fuel Management” (RMRS–87), dated April 2000 (including any subsequent revision to the report), under which—
((A)) fire regimes on the land have been moderately altered from historical ranges;
((B)) there exists a moderate risk of losing key ecosystem components from fire;
((C)) fire frequencies have increased or decreased from historical frequencies by 1 or more return intervals, resulting in moderate changes to—
((i)) the size, frequency, intensity, or severity of fires; or
((ii)) landscape patterns; and
((D)) vegetation attributes have been moderately altered from the historical range of the attributes.
((5)) ** Condition class 3** The term “condition class 3”, with respect to an area of Federal land, means the condition class description developed by the Rocky Mountain Research Station in the general technical report referred to in paragraph (4) (including any subsequent revision to the report), under which—
((A)) fire regimes on land have been significantly altered from historical ranges;
((B)) there exists a high risk of losing key ecosystem components from fire;
((C)) fire frequencies have departed from historical frequencies by multiple return intervals, resulting in dramatic changes to—
((i)) the size, frequency, intensity, or severity of fires; or
((ii)) landscape patterns; and
((D)) vegetation attributes have been significantly altered from the historical range of the attributes.
((6)) ** Day** The term “day” means—
((A)) a calendar day; or
((B)) if a deadline imposed by this subchapter would expire on a nonbusiness day, the end of the next business day.
((7)) ** Decision document** The term “decision document” means—
((A)) a decision notice (as that term is used in the Forest Service Handbook);
((B)) a decision record (as that term is used in the Bureau of Land Management Handbook); and
((C)) a record of decision (as that term is used in applicable regulations of the Council on Environmental Quality).
((8)) ** Fire regime I** The term “fire regime I” means an area—
((A)) in which historically there have been low-severity fires with a frequency of 0 through 35 years; and
((B)) that is located primarily in low elevation forests of pine, oak, or pinyon juniper.
((9)) ** Fire regime II** The term “fire regime II” means an area—
((A)) in which historically there are stand replacement severity fires with a frequency of 0 through 35 years; and
((B)) that is located primarily in low- to mid-elevation rangeland, grassland, or shrubland.
((10)) ** Fire regime III** The term “fire regime III” means an area—
((A)) in which historically there are mixed severity fires with a frequency of 35 through 100 years; and
((B)) that is located primarily in forests of mixed conifer, dry Douglas fir, or wet Ponderosa pine.
((11)) ** Implementation Plan** The term “Implementation Plan” means the Implementation Plan for the Comprehensive Strategy for a Collaborative Approach for Reducing Wildland Fire Risks to Communities and the Environment, dated May 2002, developed pursuant to the conference report to accompany the Department of the Interior and Related Agencies Appropriations Act, 2001 (House Report No. 106–64) (and subsequent revisions).1
((12)) ** Municipal water supply system** The term “municipal water supply system” means the reservoirs, canals, ditches, flumes, laterals, pipes, pipelines, and other surface facilities and systems constructed or installed for the collection, impoundment, storage, transportation, or distribution of drinking water.
((13)) ** Resource management plan** The term “resource management plan” means—
((A)) a land and resource management plan prepared for 1 or more units of land of the National Forest System described in under ; or
((B)) a land use plan prepared for 1 or more units of the public land described in under .
((14)) ** Secretary** The term “Secretary” means—
((A)) the Secretary of Agriculture, with respect to land of the National Forest System described in ; and
((B)) the Secretary of the Interior, with respect to public lands described in .
((15)) ** Threatened and endangered species habitat** The term “threatened and endangered species habitat” means Federal land identified in—
((A)) a determination that a species is an endangered species or a threatened species under the Endangered Species Act of 1973 ( et seq.);
((B)) a designation of critical habitat of the species under that Act; or
((C)) a recovery plan prepared for the species under that Act.
((16)) ** Wildland-urban interface** The term “wildland-urban interface” means—
((A)) an area within or adjacent to an at-risk community that is identified in recommendations to the Secretary in a community wildfire protection plan; or
((B)) in the case of any area for which a community wildfire protection plan is not in effect—
((i)) an area extending ½-mile from the boundary of an at-risk community;
((ii)) an area within 1½ miles of the boundary of an at-risk community, including any land that—
((I)) has a sustained steep slope that creates the potential for wildfire behavior endangering the at-risk community;
((II)) has a geographic feature that aids in creating an effective fire break, such as a road or ridge top; or
((III)) is in condition class 3, as documented by the Secretary in the project-specific environmental analysis; and
((iii)) an area that is adjacent to an evacuation route for an at-risk community that the Secretary determines, in cooperation with the at-risk community, requires hazardous fuel reduction to provide safer evacuation from the at-risk community.
