(3)
condition class 2 Federal land located within fire regime I, fire regime II, or fire regime III, in such proximity to a municipal water supply system or a stream feeding such a system within a municipal watershed that a significant risk exists that a fire disturbance event would have adverse effects on the water quality of the municipal water supply or the maintenance of the system, including a risk to water quality posed by erosion following such a fire disturbance event;
(4)
Federal land on which windthrow or blowdown, ice storm damage, the existence of an epidemic of disease or insects, or the presence of such an epidemic on immediately adjacent land and the imminent risk it will spread, poses a significant threat to an ecosystem component, or forest or rangeland resource, on the Federal land or adjacent non-Federal land; and

Federal land not covered by paragraphs (1) through (4) that contains threatened and endangered species habitat, if—
(A)
section 1533 of this title natural fire regimes on that land are identified as being important for, or wildfire is identified as a threat to, an endangered species, a threatened species, or habitat of an endangered species or threatened species in a species recovery plan prepared under , or a notice published in the Federal Register determining a species to be an endangered species or a threatened species or designating critical habitat;
(B)
the authorized hazardous fuel reduction project will provide enhanced protection from catastrophic wildfire for the endangered species, threatened species, or habitat of the endangered species or threatened species; and

Old growth stand

section 1604(g)(3)(B) of this titleThe term “old growth stand” has the meaning given the term under management direction used pursuant to paragraphs (3) and (4), based on the structure and composition characteristic of the forest type, and in accordance with applicable law, including .

(2)

Project requirements

In carrying out a covered project, the Secretary shall fully maintain, or contribute toward the restoration of, the structure and composition of old growth stands according to the pre-fire suppression old growth conditions characteristic of the forest type, taking into account the contribution of the stand to landscape fire adaptation and watershed health, and retaining the large trees contributing to old growth structure.

(3)

Newer management direction

(A)

In general

If the management direction for an old growth stand was established on or after , the Secretary shall meet the requirements of paragraph (2) in carrying out a covered project by implementing the management direction.

(B)

Any amendment or revision to management direction for which final administrative approval is granted after , shall be consistent with paragraph (2) for the purpose of carrying out covered projects.

(4)

Older management direction

(A)

In general

If the management direction for an old growth stand was established before , the Secretary shall meet the requirements of paragraph (2) in carrying out a covered project during the applicable period by implementing the management direction.

(B)

Review required

Subject to subparagraph (C), during the applicable period for management direction referred to in subparagraph (A), the Secretary shall—

review the management direction for affected covered projects, taking into account any relevant scientific information made available since the adoption of the management direction; and

(C)

Review not completed
