key ecosystem components from fire; 
(C) fire frequencies have departed (either 
increased or decreased) from historical fre-
quencies by one or more return interval, which

significantly altered from their historical range
(B) there exists a high risk of losing key 
ecosystem components from fire; 
(C) fire frequencies have departed from 
historical frequencies by multiple return inter-
vals, which results in dramatic changes to fire 
size, frequency, intensity, severity, or landscape 
patterns; and 
(D) vegetation attributes have been signifi-
cantly altered from their historical range.

SEC. 102. AUTHORIZED HAZARDOUS FUELS REDUCTION 
PROJECTS. 
(a) AUTHORIZED PROJECTS.—Subject to the remain-
der of this section, the Secretary concerned may utilize 
the process authorized by section 104 to plan and conduct 
hazardous fuels reduction projects on any of the following 
Federal lands:
(1) Federal lands located in an interface com-
munity or intermix community. 
(2) Federal lands located in such proximity to 
an interface community or intermix community that 
there is a significant risk that the spread of a fire 
disturbance event from those lands would threaten 
human life and property in the interface community 
or intermix community. 
(3) Condition class 3 or condition class 2 Fed-
eral lands located in such proximity to a municipal 
water supply system or a stream feeding a municipal 
water supply system that a significant risk exists 
that a fire disturbance event would have adverse ef-
fects on the water quality of the municipal water 
supply, including the risk to water quality posed by 
erosion following such a fire disturbance event.
(4) Condition class 3 or condition class 2 Fed-
eral lands identified by the Secretary concerned as 
an area where windthrow or blowdown, or the exist-
ence or threat of disease or insect infestation, pose 
a significant threat to forest or rangeland health or 
adjacent private lands. 
(5) Federal lands not covered by paragraph (1), 
(2), (3), or (4) that contain threatened and endan-
gered species habitat, but only if—
(A) natural fire regimes on such lands are 
identified as being important for, or wildfire is 
identified as a threat to, an endangered species, 
a threatened species, or its habitat in a species 
recovery plan prepared under section 4 of the 
Endangered Species Act of 1973 (16 U.S.C. 
1533) or in a decision document under such 
section determining a species to be an endan-
gered species or a threatened species or desig-
nating critical habitat; 
(B) the project will provide enhanced pro-
tection from catastrophic wildfire for the spe-
cies or its habitat; and 
(C) the Secretary complies with any appli-
cable guidelines specified in the species recovery 
plan prepared under the Endangered Species 
Act of 1973 (16 U.S.C. 1531 et seq.). 
(b) RELATION TO AGENCY PLANS.—An authorized 
hazardous fuels reduction project shall be planned and 
conducted in a manner consistent with the land and re-
source management plan or land use plan applicable to 
the Federal lands covered by the project. 
(c) ACREAGE LIMITATION.—Not more than a total 
of 20,000,000 acres of Federal lands may be included in
