Endangered and Threatened Wildlife and Plants; Revised Critical 
Habitat for the Preble's Meadow Jumping Mouse in Colorado

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), designate 
revised critical habitat for the Preble's meadow jumping mouse (Zapus 
hudsonius preblei) (PMJM) in Colorado, where it is listed as threatened 
in a Significant Portion of the Range (SPR) under the Endangered 
Species Act of 1973, as amended (Act). In total, approximately 411 
miles (mi) (662 kilometers (km)) of rivers and streams and 34,935 acres 
(ac) (14,138 hectares (ha)) fall within the boundaries of revised 
critical habitat in Boulder, Broomfield, Douglas, El Paso, Jefferson, 
Larimer, and Teller Counties.

DATES: This rule becomes effective on January 14, 2011.

ADDRESSES: This final rule, the economic analysis, the environmental 
assessment, comments and materials received, and supporting 
documentation we used in preparing this final rule, are available for

SUPPLEMENTARY INFORMATION:

Background

    It is our intent to discuss only those topics relevant to the 
designation of revised critical habitat in this final rule. For 
additional information on the biology of this subspecies, see our 
October 8, 2009, proposed rule to revise the designation of critical 
habitat for the PMJM (74 FR 52066); our July 10, 2008, final rule to 
amend the listing for the PMJM to specify over what portion of its 
range the subspecies is threatened (73 FR 39789); and our May 13, 1998, 
final rule to list the PMJM as threatened (63 FR 26517).

Previous Federal Actions

    On August 22, 2003, the City of Greeley filed a complaint in the 
U.S. District Court for the District of Colorado challenging our June 
23, 2003, designation of critical habitat for the PMJM (68 FR 37275) 
(City of Greeley, Colorado v. United States Fish and Wildlife Service 
et al., Case No. 03-CV-01607-AP). On December 9, 2003, the Mountain 
States Legal Foundation filed a complaint in the U.S. District Court 
for the District of Wyoming challenging our 1998 listing of the PMJM 
and designation of critical habitat for the PMJM (Mountain States Legal 
Foundation v. Gale E. Norton et al., Case No. 03-cv-250-J). That 
complaint was later expanded to include our July 10, 2008, final rule 
to amend the listing for the PMJM to specify over what portion of its 
range the subspecies is threatened (73 FR 39789) and transferred to the 
U.S. District Court for the District of Colorado (Mountain States Legal 
Foundation v. Ken Salazar et al., Case No. 1:08-cv-2775-JLK). These 
lawsuits challenged the validity of the information and reasoning we 
used to designate critical habitat for the PMJM.
    On July 20, 2007, we announced that we would review our June 23, 
2003, designation of critical habitat for the PMJM (68 FR 37275) after 
questions were raised about the integrity of scientific information we 
used and whether the decision we made was consistent with the 
appropriate legal standards (Service 2007a). Based on our review of the 
previous critical habitat designation, we determined that it was 
necessary to revise critical habitat. This rule incorporates those 
revisions that we found appropriate.
    On July 10, 2008, we amended the listing for the PMJM to specify 
over what portion of its range the subspecies is threatened (73 FR 
39789), and determined that the listing of the PMJM is limited to the 
SPR in Colorado. Upon that determination, all critical habitat 
designated in 2003 within the State of Wyoming was removed from the 
regulations at 50 CFR 17.95 for this species.
    On April 16, 2009, we reached a settlement agreement with the City 
of Greeley in which we agreed to reconsider our critical habitat 
designation for the PMJM. The settlement stipulated that we submit to 
the Federal Register a proposed rule for revised critical habitat by 
September 30, 2009, and a final rule for revised critical habitat by 
September 30, 2010 (U.S. District Court, District of Colorado 2009a). 
On June 16, 2009, an order was issued granting Mountain States Legal 
Foundation a motion to dismiss their claims on the 1998 listing and 
2008 final determination without prejudice, and stayed their challenge 
to the 2003 critical habitat designation pursuant to the City of 
Greeley settlement (U.S. District Court, District of Colorado 2009b).
    On October 8, 2009, we published a proposed rule in the Federal 
Register to revise the designation of critical habitat for the PMJM (74 
FR 52066), and accepted public comments for 60 days (from October 8 to 
December 7, 2009). On May 27, 2010, we opened a second comment period 
of 30 days (from May 27 to June 28, 2010) and requested comments on our 
draft economic analysis (DEA) (Industrial Economics 2010a), draft 
environmental assessment, amended Required Determinations section of 
the proposed rule, and any other part of our proposed revised critical 
habitat designation (75 FR 29700). On August 9, 2010, an agreement with 
the City of Greeley extended the date for submission of the final rule 
for revised critical habitat to the Federal Register to December 1, 
2010 (U.S. District Court, District of Colorado 2010).
    For additional information about previous Federal actions 
concerning the PMJM, see our July 10, 2008, rule for the PMJM to 
specify over what portion of its range the subspecies is threatened (73 
FR 39789).

Summary of Comments and Recommendations

    We requested written comments from the public on the proposed 
designation of revised critical habitat for the PMJM during the two 
comment periods. The first comment period, associated with the 
publication of the proposed rule to revise the designation of critical 
habitat for the PMJM (74 FR 52066) opened on October 8, 2009, and 
closed on December 7, 2009. We opened a second comment period on our 
DEA, draft environmental assessment, amended Required Determinations 
section of the proposed rule, and any other part of our proposed 
revised critical habitat designation (75 FR 29700) on May 27, 2010, and 
closed it on June 28, 2010. We also contacted peer reviewers; 
appropriate Federal, State, and local agencies; scientific 
organizations; and other interested parties, and invited

[[Page 78431]]

them to comment on the proposed rule and supporting documents.
    We received 45 comments in response to the proposed rule. Comments 
were received from 2 peer reviewers, 1 Federal agency, 1 State agency, 
and 8 local governmental entities, 7 non-government organizations, and 
18 private individuals (including 14 via similar post cards). Thirty-
seven comments were received during the October 8 to December 7, 2009, 
comment period. Eight comments were received during the May 27 to June 
28, 2010, comment period, all but one from entities that had commented 
previously. We received no requests for public hearings. All 
substantive comments have been either incorporated into the final 
determination or are addressed below.

Peer Review

    In accordance with our policy published in the Federal Register on 
July 1, 1994 (59 FR 34270), we solicited expert opinions from three 
knowledgeable individuals with scientific expertise that included 
familiarity with the species, the geographic region in which the 
species occurs, and conservation biology principles. We received 
responses from two of the peer reviewers that we contacted. The peer 
reviewers generally agreed that we relied on the best scientific 
information available, accurately described the species and its habitat 
requirements, and concurred that our critical habitat proposal was well 
supported. The peer reviewers provided additional suggestions to 
improve the final critical habitat rule. Recommended editorial 
revisions and clarifications have been incorporated into the final rule 
as appropriate. We respond to all substantive comments below.

Comments From Peer Reviewers

    (1) Comment: One peer reviewer commented that upstream and adjacent 
habitat, beyond designated critical habitat, requires management to 
decrease potential for catastrophic wildfire and flooding, and to 
maintain appropriate stream flow and channel integrity.
    Our Response: We agree. Federal agencies are directed, under 
section 7(a)(1) of the Act (16 U.S.C. 1531 et seq.), to utilize their 
authorities to carry out programs for the conservation of endangered 
and threatened species. Proactive management on U.S. Forest Service 
(USFS) and other Federal lands upstream or outward from designated 
critical habitat should consider implications to the PMJM and its 
critical habitat. In addition, section 7(a)(2) of the Act requires 
every Federal agency to insure that any action it authorizes, funds, or 
carries out is not likely to jeopardize the continued existence of a 
listed species or result in the destruction or adverse modification of 
designated critical habitat. The activity does not have to take place 
within PMJM habitat or critical habitat to be subject to section 7 
consultation. In considering the effects of a proposed action, the 
Federal agency looks at both the direct and indirect effects of an 
action on the species or critical habitat. Indirect effects are caused 
by the proposed action, are later in time, and are reasonably certain 
to occur. If, for example, management activities on Federal land, or a 
Federal permit or Federal funding for an activity upstream of critical 
habitat, may result in increased runoff, sedimentation, or channel 
alteration within critical habitat, those effects must be considered by 
the Federal agency. Outside of Federal lands and when no Federal nexus 
is present, cooperative conservation efforts with State and local 
government, and private property owners are the most effective means of 
addressing appropriate land management.
    (2) Comment: One peer reviewer commented that we should have 
emphasized the relationship of ``subshrub cover'' (low-growing woody 
shrubs or perennial plants with a woody base) and plant species 
richness with the presence of PMJM.
    Our Response: We agree that these concepts are important to PMJM 
habitat. Low shrub cover and species richness are correlated with 
occupancy of riparian corridors by the PMJM. These relationships may be 
significant and are described in Clippinger (2002, p. 73). The primary 
constituent elements (PCEs) of critical habitat for the PMJM are 
described more broadly and include riparian corridors, in part, 
``containing dense, riparian vegetation consisting of grasses, forbs, 
or shrubs, or any combination thereof.'' We believe that this final 
rule appropriately captures the importance of the low, diverse 
vegetative cover essential to the conservation of PMJM.
    (3) Comment: One peer reviewer maintained that our explanation of 
why Buffalo Creek and Wigwam Creek (Jefferson County) were not included 
as proposed critical habitat should be better supported.
    Our Response: Areas along both Buffalo Creek and Wigwam Creek have 
been subject to catastrophic fires. These events caused subsequent 
flooding and increased sedimentation of these streams. Trapping efforts 
targeting PMJM have not been conducted in these areas since the fires; 
however, it is unlikely that severely burned areas are currently 
occupied by the PMJM. The areas remain degraded and for at least the 
near future will not support the PCEs necessary for the conservation of 
the PMJM in the appropriate quantity and spatial arrangement to support 
inclusion as critical habitat. Given the extent of critical habitat 
proposed elsewhere in this subdrainage, we conclude that it is not 
necessary or appropriate to designate critical habitat in these 
degraded stream reaches.
    (4) Comment: One peer reviewer suggested that our failure to 
propose critical habitat on the Big Thompson River, North Fork of the 
Big Thompson River, and Little Thompson River was based more on issues 
of land ownership than on science.
    Our Response: All three of these rivers are within the Big Thompson 
River subdrainage (subdrainages equate to U.S. Geological Survey 8-
digit hydrological unit boundaries and are hereafter referred to as 
HUCs). Within this HUC we are designating Buckhorn Creek (Unit 3) and 
Cedar Creek (Unit 4) as critical habitat, but we identified no other 
areas that merited designation. Public lands, especially undeveloped 
Federal lands and other public lands currently devoted to conservation, 
are more likely to support viable PMJM populations, both currently and 
in the future. We made our determinations after examining both quality 
of existing habitat and land ownership, and prioritized designation of 
Federal lands within this HUC.

Public Comments

Biological Concerns and Methodology
    (5) Comment: One commenter stated that proposed critical habitat 
should be expanded to reflect understanding of genetic diversity within 
the PMJM.
    Our Response: Our designation of revised critical habitat 
incorporates current knowledge of genetic diversity in the PMJM. 
Genetic analysis has revealed significant differences between PMJM 
populations in northern and southern portions of the range (King et al. 
2006, pp. 4337-4338). The Preble's Meadow Jumping Mouse Recovery Team 
(Jackson 2009, pers. comm.) concluded that recovery populations 
outlined in the Working Draft of a Recovery Plan (PMJM Recovery Team 
2003), and included in the Preliminary Draft Recovery Plan (Draft Plan) 
(Service 2003a), were spread north and south to provide adequate 
representation of the genetic differences in northern and

[[Page 78432]]

southern portions of the range examined in King et al. (2006). This 
same approximate distribution in populations north and south is 
reflected in this revised critical habitat designation.
    (6) Comment: One commenter urged the Service to consider the value 
of expanding proposed critical habitat to provide habitat linkage for 
PMJM populations north and south of Denver, and among other drainages 
where critical habitat was proposed.
    Our Response: Potential connectivity of critical habitat was 
considered consistent with our conservation strategy and that proposed 
in the Draft Plan. In most cases, revised critical habitat units exceed 
minimum reach lengths for large, medium, and small populations proposed 
in the Draft Plan. All designated critical habitat units and subunits 
exceed 3 mi (5 km) in stream length, the minimum length of stream the 
Draft Plan prescribes for a small recovery population. In some cases, 
we chose not to link stream reaches through the designation of marginal 
habitat, or not to substantially extend critical habitat to encompass a 
larger PMJM population, where multiple smaller recovery populations are 
consistent with our conservation strategy.
    (7) Comment: One commenter requested that, before designating 
revised critical habitat, the Service should consult with scientists 
regarding how climate change may affect PMJM movement, habitat needs, 
and habitat connectivity. For example, it was suggested that we should 
consider potential effects of changes in precipitation and earlier 
spring runoff.
    Our Response: Variability in existing climate models suggests 
uncertainty as to future climate change and potential effects in 
Colorado, where the PMJM is listed. We have considered the potential 
impact of future climate change on the PMJM, and we believe that our 
revised designation adequately addresses likely climate change 
scenarios by designating critical habitat areas throughout the north-
south range of the PMJM in Colorado that vary in elevation and in 
stream size (see Climate Change, below). In the Big Thompson River and 
Upper South Platte River drainages, we are designating critical habitat 
units in excess of those recovery populations called for in the Draft 
Plan to provide resilience, should climate change reduce the value of 
lower elevation habitats currently occupied by the PMJM. These units, 
the Cache La Poudre Unit (Unit 2) and the Upper South Platte Unit (Unit 
11), are centered on Federal lands and include reaches extending to the 
highest elevation the PMJM is currently known to occupy in Colorado. 
If, in the future, a clearer picture of the effects of climate change 
on the PMJM is developed, further revision of critical habitat may be 
appropriate (see also Climate Change, below).
    (8) Comment: One commenter stated that both sites where trapping 
has documented PMJM presence since 2003, and sites of earlier captures, 
should be included in designated critical habitat.
    Our Response: Not all areas where the PMJM is known to occur in 
Colorado are being designated as revised critical habitat. See our 
response to comment 44. We incorporated the best scientific and 
commercial information available into this final rule, including 
information regarding all locations where PMJM have been trapped since 
our 2003 final rule. These more recent capture locations did not 
significantly expand the known distribution of the PMJM in Colorado. 
However, we did consider each new capture location and its potential 
significance prior to our proposing revised critical habitat for the 
PMJM.
    (9) Comment: One commenter stated that the Draft Plan for the PMJM, 
which was cited as a basis for the Service's conservation strategy and 
certain decisions regarding proposed designation of revised critical 
habitat, is 6 years old and does not include current data.
    Our Response: The 2003 Draft Plan (Service 2003a) provides a 
conservation strategy for the PMJM. It was developed primarily by the 
PMJM Recovery Team and refined through comments and additional 
information we received. Information on range, occupancy, populations, 
and habitat characteristics were used in developing the Draft Plan. 
Recent review by the current PMJM Recovery Team has verified that 
concepts and strategies incorporated into the Draft Plan remain 
appropriate (Jackson 2010, pers. comm.). However, we also incorporated 
new data, as appropriate, in developing our proposal and this final 
rule, including trapping results, genetic and morphometric confirmation 
of species identification, and changes to habitat.
    (10) Comment: One commenter pointed out that the Service has not 
proposed critical habitat to address all recovery populations called 
for in the Draft Plan, including HUCs where the PMJM is known to occur.
    Our Response: While the conservation strategy underlying our 
proposed revision of critical habitat was informed by the Draft Plan 
and the ongoing recovery planning process, areas we are designating as 
revised critical habitat in this rule will not be identical to areas 
ultimately designated as recovery populations. The Draft Plan 
designated location of certain recovery populations in HUCs where PMJM 
are known to be present. However, in some HUCs within the likely range 
of the PMJM, there is little or no available information on the 
existence of PMJM populations or the extent of occupied habitat. In 
these cases, the Draft Plan only applied standard criteria to achieve 
recovery of the species. For example, the Draft Plan required, at 
minimum, three small recovery populations or one medium recovery 
population in several HUCs, but only if the HUC was found to be 
occupied by the PMJM. Since we have determined that the conservation of 
the PMJM can be achieved by designating critical habitat in areas that 
are known to support the species, rather than in areas with no 
confirmed occupancy by the species, we are designating no critical 
habitat in HUCs where occupancy has not been confirmed. In other cases, 
such as the Kiowa HUC in Elbert County, trapping efforts have been 
limited to sites of human development, and, while there is confirmed 
occurrence of the PMJM, it is not sufficient to inform us of 
distribution or abundance within the HUC. We exercised our professional 
judgment and determined that those limited areas of confirmed 
occurrence of the PMJM in and near human development are not essential 
to the conservation of the PMJM. We are not designating such sites as 
critical habitat.
    (11) Comment: One commenter stated that areas of critical habitat 
should be designated in excess of recovery goals suggested in the Draft 
Plan.
    Our Response: In two HUCs, we are designating critical habitat 
units beyond those recovery populations that the Draft Plan specifies. 
We are designating critical habitat capable of supporting a large PMJM 
population independent of, and in addition to, the large recovery 
populations proposed in the Draft Plan along the Cache la Poudre River 
(Unit 2) in the Cache La Poudre River HUC and designated reaches of the 
Upper South Platte River and its tributaries (Unit 10) in excess of 
recovery goals for the Upper South Platte River HUC. In other HUCs, we 
did not identify or designate additional areas that met the definition 
of critical habitat in excess of recovery goals stated in the Draft 
Plan.
    (12) Comment: Multiple commenters stated that the outward extent of 
proposed critical habitat did not accurately reflect limits of PMJM 
habitat. One commenter stated that distance outward from riparian 
vegetation is a much better predictor of PMJM habitat than is our use 
of distance

[[Page 78433]]

from the stream edge, based on stream order (a classification of 
streams by relative size). Another commenter stated that floodplain 
plus 100 meters should be used as the outward boundary of critical 
habitat on reaches where floodplain mapping is available.
    Our Response: We believe that the outward extent of critical 
habitat we are designating includes all PCEs required by the PMJM and 
effectively protects habitat essential to the conservation of the PMJM. 
We agree that site-specific assessment of habitat components, including 
extent of riparian vegetation, is a more precise method of designating 
critical habitat (see our response to comment 14 below). However, site-
specific mapping of PMJM habitat in Colorado is not generally 
available. Land use and recent site history complicate efforts to 
accurately assess and map riparian habitat limits. Floodplain mapping 
is not available for most foothill streams designated as PMJM critical 
habitat. Where limits of the designated 100-year floodplain have been 
mapped, floodplain limits are often revised, especially in the Colorado 
Front Range development corridor, where filling of the floodplain may 
occur and flood levels are altered by development. We used the best 
available scientific and commercial information with respect to 
determining the outward extent of PMJM critical habitat.
    (13) Comment: One commenter suggested that the Service should 
provide detail on the development of the average floodplain widths used 
to designate outward limits of critical habitat for streams of 
different order and stated that the calculation needs to be based on a 
sufficient sample of sites across PMJM range to be meaningful.
    Our Response: The estimates of average floodplain width based on 
stream order that we use in this designation of critical habitat were 
previously developed in conjunction with our June 23, 2003, designation 
of critical habitat for the PMJM (68 FR 37275). We believe that a 
sufficient number of representative streams were examined to provide an 
appropriate estimation of average floodplain width as related to stream 
order.
    (14) Comment: One commenter stated that the Riparian Conservation 
Zone (RCZ) mapping, developed as part of the approved Douglas County 
Habitat Conservation Plan (HCP), corresponds better to appropriate 
outward limits of critical habitat than do the boundaries that the 
Service proposed for revised critical habitat, and that critical 
habitat boundaries should align with county-wide HCP boundaries for 
consistency and to avoid confusion.
    Our Response: We agree that it is preferable that critical habitat 
boundaries match HCP boundaries where HCP boundaries accurately reflect 
limits of habitat essential to the conservation of the PMJM. RCZ 
boundaries in the Douglas County HCP were developed based on 
conservation strategies for the PMJM provided in the Draft Plan. After 
consideration, we are designating the outward boundaries of revised 
critical habitat on non-Federal lands in Douglas County to correspond 
to the boundaries developed for RCZ (see the Delineation of Critical 
Habitat Boundaries section).
Procedural and Legal Issues
    (15) Comment: Two commenters stated that the Service cannot propose 
a critical habitat revision prior to analysis of alternatives under the 
National Environmental Policy Act (NEPA) (42 U.S.C. 4321 et seq.), a 
draft economic analysis (DEA), and a Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) analysis. They stated that the environmental and 
economic impacts of the proposed action must be considered prior to the 
proposal.
    Our Response: By Service policy, we draft and circulate the NEPA, 
DEA, and Regulatory Flexibility Act analyses between the proposed and 
final critical habitat designation. Comments on the entire proposal, 
including the draft environmental assessment, DEA, and Regulatory 
Flexibility Act analysis, were accepted for 30 days following the May 
27, 2010, publication making available these documents (75 FR 29700). 
The information provided in these documents and comments regarding them 
were fully considered prior to this final rule, in accordance with 
applicable regulations and statutes.
    (16) Comment: Two commenters stated that the Service 
inappropriately proposed critical habitat in areas where the PMJM was 
not known to exist at the time of listing.
    Our Response: Section 3(5)(A) of the Act defines critical habitat, 
in part, as those specific areas within the geographic area occupied by 
the species at the time of listing, and specific areas outside the 
geographic area occupied by the species at the time of listing upon 
determination that such areas are essential for the conservation of the 
species. Our designation constitutes our best assessment of areas 
determined to be within the geographical area occupied at the time of 
listing that contain the physical and biological features essential to 
the conservation of the PMJM that may require special management, and 
those additional areas not occupied at the time of listing, but that 
have been determined to be essential to the conservation of the PMJM. 
Management and protection of all the areas is necessary to achieve the 
conservation of PMJM. Therefore, we are also designating areas that 
were not known to be occupied at the time of listing, but which were 
subsequently identified as being occupied, and which we have determined 
to be essential to the conservation of the PMJM in our Preliminary 
Draft Recovery Plan (Service 2003a). We have based our critical habitat 
designation on the best currently available scientific information.
    (17) Comment: One commenter stated that only areas ``indispensible 
and absolutely necessary'' to the PMJM should be designated as critical 
habitat and that the Service should include only the ``minimum amount 
of habitat needed to avoid short-term jeopardy'' (citing Middle Rio 
Grande Conservancy District v. Babbitt). Based on this reasoning, they 
asserted that we could not tie critical habitat to the Draft Plan, 
which addresses long-term recovery.
    Our Response: Within the range of the listed species, critical 
habitat is defined to include areas occupied at the time of listing on 
which are found those physical or biological features essential to the 
conservation of the species, and which may require special management 
considerations or protection, and those additional areas not occupied 
at the time of listing but that have been determined to be essential to 
the conservation of the species. Conservation is defined in the Act as 
the use of all methods and procedures which are necessary to bring any 
endangered or threatened species to the point at which the measures 
provided under the Act are no longer necessary. Limiting designation of 
critical habitat to avoiding ``short-term jeopardy'' would not meet the 
Act's intent that critical habitat provide for the conservation (e.g., 
recovery) of the species.
    (18) Comment: One commenter expressed the concern that details of 
all existing HCPs involving the PMJM were not readily available for 
public review and that all HCPs should be available on the Service's 
``ECOS'' Web site and the Service's Mountain-Prairie Region Web site.
    Our Response: Most HCPs that address the PMJM have been available 
to the public on our ECOS Web site. When we were made aware that 
certain HCPs were not posted, we provided the commenter the requested 
materials as expeditiously as possible.

[[Page 78434]]

    (19) Comment: One commenter stated that Geographic Information 
System (GIS) data depicting proposed critical habitat boundaries should 
have been made available for public review.
    Our Response: We provided GIS depictions of proposed critical 
habitat when requested. Additionally, we believe that the legal 
description of stream reaches and outward distances from streams that 
we provided in our proposal to revise the designation of critical 
habitat were adequate to identify the areas proposed.
    (20) Comment: One commenter recommended that we incorporate a 
provision in our critical habitat designation that would exclude from 
critical habitat areas covered by future HCPs, when completed.
    Our Response: The basis for exclusions from critical habitat under 
section 4(b)(2) of the Act is explained in ``Exclusions'' below. We 
cannot make a determination now to exclude areas covered by HCPs that 
may be developed sometime in the future, because we have no way to 
evaluate the effectiveness, and determine whether the benefits of 
exclusion outweigh the benefits of inclusion, of plans that do not yet 
exist and have not been implemented. If, in the future, we determine 
that changes in designated critical habitat for the PMJM are 
appropriate, we have the option to revise critical habitat.
    (21) Comment: One commenter asked us to confirm that the existing 
special 4(d) rule, which exempts take of PMJM under section 9 of the 
Act for specified activities, including ditch maintenance and any 
continued use of perfected water rights, is not affected by the 
designation of critical habitat.
    Our Response: The 4(d) rule for the PMJM (see 50 CFR 17.40 (l)) 
provides certain exemptions from the take prohibitions found in section 
9 of the Act. Take prohibitions under section 9 are not affected by the 
designation of critical habitat. The primary regulatory effects of a 
critical habitat designation under the Act are triggered through the 
provisions of section 7 of the Act, which applies only to activities 
conducted, authorized, or funded by a Federal agency. In limited cases, 
an activity that is excluded from take provisions under the 4(d) rule 
may require a Federal permit or involve Federal funding. In these 
cases, while take would be exempted under the 4(d) rule, section 7 
consultation would still occur to ensure that Federal actions would not 
jeopardize the PMJM or result in destruction or adverse modification of 
its critical habitat.
    (22) Comment: One commenter stated that under the Act, the Service 
must re-consult on any projects within newly designated critical 
habitat that previously underwent section 7 consultation.
    Our Response: For Federal actions, the lead Federal agency 
determines whether their action may affect designated PMJM critical 
habitat. This applies to projects previously consulted on under section 
7 where the Federal agency has retained discretionary involvement or 
control over the action. Federal agencies may sometimes need to request 
reinitiation of consultation on actions for which formal consultation 
has been completed (see 50 CFR 402.16).
Comments on Specific Units
    (23) Comment: One commenter requested us to connect critical 
habitat Units 1 (North Fork of the Cache la Poudre River) and 2 (Cache 
la Poudre River) in Larimer County.
    Our Response: The Milton Seaman Reservoir at the downstream extent 
of Unit 1 is a barrier to PMJM movement and effectively prevents 
linking of the two units. We do not believe that it is biologically 
necessary or possible to link these two units. See also our response to 
Comment 6.
    (24) Comment: One commenter called for us to exclude the area 
proposed as critical habitat in Unit 1 (North Fork of the Cache la 
Poudre River) on the mainstem of the North Fork of the Cache la Poudre 
River upstream of the Milton Seaman Reservoir and within the footprint 
of the proposed reservoir expansion.
    Our Response: We have not excluded this reach from designated 
critical habitat. This area includes Federal and State property that 
would potentially be inundated by the City of Greeley's proposed 
expansion of the Milton Seaman Reservoir. Expansion under the currently 
proposed plan would inundate about 3 mi (5 km) of the river. In 2002, 
the City of Greeley contended that the reach in question supported only 
patches of willow shrub, had little habitat for the PMJM, and did not 
meet the definition of critical habitat (Kolanz 2003). In our on June 
23, 2003, designation of critical habitat (68 FR 37275), we concluded 
the area in question supported those physical or biological features 
essential to the conservation of the species, and may require special 
management considerations or protection. We stated that, within the 
reach in question, some habitat components appeared discontinuous, and 
PMJM habitat was, at that time, of lower quality than habitat upstream 
of this reach, due to heavy grazing. However, we concluded that the 
area in question did include the requisite PCEs to support the PMJM, 
and its designation as critical habitat was essential for the 
conservation of the large PMJM population along the North Fork of the 
Cache la Poudre River. The Service chose not to exclude this reach from 
critical habitat in 2003. This prompted the legal actions by the City 
of Greeley addressed in ``Previous Federal Actions'' above.
    The City of Greeley, in a letter dated May 20, 2009, outlined its 
concerns regarding designation of critical habitat in this area, and 
requested exclusion of the area from revised critical habitat under 
section 4(b)(2) of the Act (Kolanz 2009a). The City of Greeley also 
submitted a report by ERO Resources Corporation (ERO) assessing the 
area to be inundated by the proposed reservoir expansion (ERO 2008). 
ERO concluded that of the approximately 165 ac (66.8 ha) of designated 
critical habitat that would be inundated, only about 26 acres were of 
moderate to high quality for the PMJM. Non-habitat and low-quality 
habitat were attributed to the dominant upland vegetation and steep 
slopes, while the moderate- to high-quality habitat was associated with 
the narrow riparian corridor (ERO 2008, pp. 11-12). In our October 8, 
2009, proposal to revise the designation of critical habitat for the 
PMJM (74 FR 52066), we again determined that the area met the 
definition of critical habitat, that it included physical and 
biological features that are essential to the conservation of the 
species and that may require special management considerations or 
protection. Three other letters from the City of Greeley followed, two 
within public comment periods for the proposed revised critical 
habitat, expanding on the City of Greeley's concerns (Kolanz, 2009b, 
2009c, 2010).
    Consistent with previously stated concerns over habitat quality, 
the City of Greeley contended that the area in question is not 
essential to the conservation of the PMJM. The City of Greeley pointed 
out that it was not mapped as PMJM habitat in our proposal to establish 
special regulations for the conservation of the PMJM (December 3, 1998, 
63 FR 66777), and was not shown to be ``occupied'' by PMJM in a recent 
Colorado Division of Wildlife (CDOW) database. The reach in question is 
part of the USFS Greyrock Grazing Allotment, which extends from Milton 
Seaman Reservoir, approximately 3 mi (5 km) upstream, and includes 
lands owned primarily by the USFS (about 2 mi (3 km) of the stream), as 
well as State lands, City of Greeley lands, and private lands (USFS

[[Page 78435]]

2008). The USFS 2008 Biological Assessment for management of the 
Greyrock Grazing Allotment explains the history of the site and past 
habitat limitations (USFS 2008). Heavy livestock grazing for many 
decades drastically reduced riparian shrubs and trees. In the last 7 
years, riparian habitat quality has significantly improved in the 
reach. Following removal of grazing along the North Fork of the Cache 
la Poudre River, a notable increase in willow growth and a tall, dense 
herbaceous component of the plant community was observed in the 
riparian zone in 2007. With no further livestock grazing in the reach 
through 2010, a lush riparian community has developed that provides 
PCEs essential to the support of the PMJM, in quantity and spatial 
arrangement that suggests riparian habitat is now of high quality. 
Upland habitat in the reach has been slower to recover following heavy 
grazing, and weed control efforts are needed. While the PMJM had been 
documented upstream in this drainage, the reach above Milton Seaman 
Reservoir had not been trapped to establish whether the PMJM was 
present until 2010, when a limited trapping effort by the USFS captured 
a jumping mouse within the proposed reservoir expansion area (USFS 
2010). The CDOW database will be updated accordingly. Restoration of 
habitat in this reach has advanced to the point where grazing will 
again take place on the allotment. Carefully managed grazing will 
maintain or improve PMJM habitat in this allotment into the future. The 
USFS has informally consulted with the Service over management of this 
allotment and we have concluded that carefully managed grazing will 
maintain or improve PMJM habitat on the allotment into the future.
    The City of Greeley also stated that designation of critical 
habitat in this area would create significant financial burden on the 
City. Our DEA (section 5.3) assigns a low incremental cost ($20,000 to 
$38,000) to the designation of critical habitat for the Halligan 
Reservoir and Milton Seaman Reservoir projects. However, additional 
costs could be incurred should designation of critical habitat affect 
regulatory approval of the proposed project, and cause the City of 
Greeley to pursue a more costly alternative. Because of their 
speculative nature, these costs were not included in the DEA (see our 
response to Comment 56), but we discuss them in the FEA and here. Under 
section 7 of the Act, the Service will evaluate whether any proposed 
alternative for Milton Seaman Reservoir expansion under permit review 
by the U.S. Army Corps of Engineers (Corps) will jeopardize the PMJM or 
result in destruction or adverse modification of its designated 
critical habitat. Under the City of Greeley's worst case scenario, our 
designation of critical habitat and subsequent consultation regarding 
the reservoir project could result in a finding of ``destruction or 
adverse modification of critical habitat'' by the Service, or could 
result in the Corps denying a permit under the Clean Water Act (33 
U.S.C. 1251 et seq.), based on the proposed project not being the 
``least damaging practicable alternative.'' To be attributable to our 
designation of critical habitat, an outcome and any resultant costs 
would have to differ from the results of regulatory review of the same 
project with no critical habitat designation. For example, the outcome 
would have to differ from the result of Service consultation in the 
absence of critical habitat that results in a jeopardy determination, 
or in the absence of critical habitat, the Corps denying a permit based 
on the presence of the PMJM, combined with an array of other 
considerations. The question of whether regulatory review under 
scenarios with or without critical habitat would produce different 
results contributes to the speculative nature of costs attributable to 
critical habitat designation. Factors relevant to possible future 
Service and Corps regulatory determinations follow.
    Substantial planning has taken place between the City of Greeley, 
the Service, The Nature Conservancy, and other entities, to address 
potential impacts to the PMJM and its habitat from the planned 
reservoir expansion. The City of Greeley has expressed an interest in 
implementing conservation measures to offset impact of the proposed 
project to the PMJM prior to project construction. Conservation 
measures have been identified that could serve to offset project 
impacts to the PMJM, should the planned project move forward. These 
conservation measures are targeted at PMJM populations and supporting 
ecological processes in critical habitat Unit 1, which includes the 
reservoir expansion area. Further development of conservation measures 
and their incorporation into plans for proposed reservoir expansion 
could help maintain the value of this critical habitat unit to the 
recovery of the PMJM and reduce or eliminate the possibility of a 
jeopardy or adverse modification determination by the Service.
    Our designation of critical habitat for the PMJM should be 
considered by the Corps as indicative of the high natural resource 
value of the lands designated. A decision that the area does not meet 
the definition of critical habitat would imply a lesser resource value. 
However, if the Service were to exclude the reach in question from 
critical habitat for reasons of relevant non-biological factors 
(economic, social, etc.), it would not change our determination that 
the area meets the definition of critical habitat, nor would it change 
the inherent resource value of the reach or its contribution to the 
conservation and recovery of the PMJM. Therefore, from a resource 
perspective, the Corps' assessment of the value of this reach and its 
role in their consideration of issuing a permit to the City of Greeley 
may not differ between the cases of critical habitat designation and 
exclusion from designation based on non-biological factors.
    Any future Milton Seaman Reservoir expansion may differ from the 
project currently proposed. The City of Greeley is an active 
participant in the Halligan-Seaman Water Management Project. To 
efficiently manage their supplies, the cities of Fort Collins and 
Greeley have proposed the Halligan-Seaman Water Management Project as a 
regional water storage and management project on the North Fork of the 
Cache la Poudre River. Both cities and their partners are working 
together to increase water storage capacity for their communities 
through coordinated enlargements of Halligan and Milton Seaman 
reservoirs. The participants are using an innovative Shared Vision 
Planning process, which brings together stakeholders in a collaborative 
planning and model building exercise. The Service is supportive of this 
process, has participated as resources allow, and anticipates that its 
results will inform the Halligan-Seaman Water Management Project. The 
eventual proposal for Milton Seaman Reservoir expansion may vary from 
the proposal currently envisioned, to facilitate coordinated management 
of these reservoirs.
    Onsite alternatives to the project currently proposed by the City 
of Greeley may result from the Halligan-Seaman Water Management 
Project. Such alternatives could reduce the probability of a Service 
determination of adverse modification of critical habitat, or Corps 
permit denial based on presence of critical habitat. Any such 
alternatives could, however, also result in less water storage or 
storage at a higher cost.
    The most costly possible result of our designation of critical 
habitat would be a case where the City of Greeley would have to abandon 
expansion plans for the Milton Seaman Reservoir, and develop

[[Page 78436]]

storage options at one or more alternate sites. Assuming a current 
estimated cost of $116 million for the proposed project (Kolanz 2010, 
p. 4) and the Corps' estimated costs of alternate storage cited in the 
DEA (up to 8 times the cost of storage through Milton Seaman Reservoir 
expansion), additional cost due to designation of critical habitat 
could range to $812 million. The Corps' estimates relate to comparative 
costs incurred by other Front Range Colorado water projects (Peter, 
pers. comm. 2010).
    Under the scenarios above, the additional cost to the City of 
Greeley associated with critical habitat designation upstream of the 
Milton Seaman Reservoir could range from $20,000 to as high as $812 
million. We have considered both the potential costs due to designation 
of critical habitat, and the relative likelihood of their occurrence, 
when evaluating the City of Greeley's request for exclusion.
    The reach of river above the Milton Seaman Reservoir is part of 
critical habitat Unit 1, established to be consistent with a large 
recovery population along the North Fork of the Cache La Poudre River 
and its tributaries, as designated in the Draft Plan. The entire reach 
of the North Fork between the Halligan Reservoir to the north and 
Milton Seaman Reservoir to the south is within this unit. The two 
reservoirs create barriers to PMJM movement along the river, and the 
population of PMJM between the reservoirs and on adjoining tributaries 
is thought to be relatively isolated from populations elsewhere. The 
City of Greeley contends that loss of up to 3 mi (5 km) of the 
approximately 88 mi (140 km) in this critical habitat unit will have 
little relative impact on the unit's ability to conserve and recover 
the PMJM. We do not know the extent of habitat needed to support a 
large recovery population as described in the Draft Plan. At a minimum, 
a total of 50 mi (80 km) of connected streams and tributaries is 
suggested for a large PMJM population in the Draft Plan. But the Draft 
Plan bases size of PMJM recovery populations on the numbers of PMJM 
present, not the extent of habitat. Until such time as population 
estimates for the area are developed, we will not know whether 50 mi 
(80 km), or even 88 mi (140 km), of streams will be sufficient. In this 
context, loss of 3 of the 88 mi (5 of the 140 km) may significantly 
impact the ability of the critical habitat unit to support a large 
population and meet the recovery goal outlined in the Draft Plan.
    The City of Greeley suggested that an exclusion would support 
ongoing Federal and local cooperation in the development of water 
resources in the drainage. Water use and storage issues continue to 
generate close scrutiny in Colorado. The Milton Seaman Reservoir 
expansion, Halligan Reservoir expansion, and other proposed projects 
have both their proponents and critics. While an exclusion could lead 
to the continuation and strengthening of partnerships between the City 
of Greeley, certain other public and private entities, and the Service, 
it would likely alienate others. Despite our decision not to exclude 
the area above Milton Seaman Reservoir from critical habitat 
designation, we anticipate a continued working relationship with the 
City of Greeley to address both their needs and those of the PMJM.
    If approved, the proposed reservoir expansion would occur well in 
the future. The required review under NEPA and the permit issuance by 
the Corps under the section 404 of the Clean Water Act, necessary for 
reconstruction of the reservoir's dam, are likely to take years. 
Because of this, considerable uncertainty exists regarding when and in 
what form an expansion of Milton Seaman Reservoir might occur. Given 
the uncertainties regarding timing, design, and future conservation 
commitments associated with reservoir expansion, exclusion of the area, 
even if it should be determined to be appropriate someday in the 
future, is premature.
    Exclusion of this reach from critical habitat would do little to 
relieve the costs of regulatory review and associated permitting 
(delays, administrative costs, consulting costs, and cost of developing 
additional conservation measures) for the City of Greeley. The area of 
the proposed expansion includes Federal land owned by the USFS. All 
alternatives impacting this land will involve USFS approval. In 
addition, any dam replacement or reconstruction would require a permit 
from the Corps under the Clean Water Act. Even without critical 
habitat, section 7 review appears unavoidable. Exclusion from critical 
habitat would not alleviate the need for section 7 consultation, or 
appreciably increase the administrative costs involved.
    Designation of critical habitat (the identification of lands that 
are necessary for the conservation of the species) is beneficial in the 
recovery planning for a species. In this case, the Draft Plan has 
helped inform critical habitat designation by designating a large 
recovery population in this area. This final rule may, in turn, 
contribute to the development of a final recovery plan for the North 
Fork of the Cache La Poudre River.
    We have determined that this portion of the North Fork of the Cache 
la Poudre River contains the physical and biological features essential 
to the conservation of the PMJM in accordance with 4(a)(3) of the Act. 
We conclude that it is inappropriate to exclude this reach from 
critical habitat under section 4(b)(2) of the Act.
    (25) Comment: Two commenters pointed out that critical habitat 
proposed along Spring Brook and South Boulder Creek in Unit 5 (South 
Boulder Creek), Boulder County, is discontinuous as mapped.
    Our Response: PMJM have been found on both Spring Brook and South 
Boulder Creek. Spring Brook has been diverted into a canal; therefore, 
it does not follow its historical course directly into South Boulder 
Creek. The limits of critical habitat we are designating for the two 
reaches are separated by approximately 100 ft (30 m) through a rural 
residential upland area which may not contain the physical and 
biological features essential for the conservation of PMJM, as defined. 
However, we do not believe that this discontinuity significantly 
affects the species' ability to move between these portions of this 
critical habitat unit.
    (26) Comment: The City of Boulder requested that we coordinate with 
the City to ``fine tune'' the boundaries of Unit 5 (South Boulder 
Creek) to expedite regulatory review of future projects with a Federal 
nexus.
    Our Response: As in other units, based on the scale of our mapping, 
there may be some areas within the general boundaries of designated 
critical habitat in Unit 5 that do not support PCEs required by the 
PMJM. For example, specific areas that support existing buildings, 
roads, and parking lots are not considered critical habitat. These 
areas are excluded by text in this rule. We will continue to be 
available to work with the City of Boulder to determine boundaries of 
areas that do not meet the definition of critical habitat.
    (27) Comment: The U.S. Department of Energy (DOE) commented that it 
controls much of the ``Rocky Flats Site,'' described by the Service as 
the Rocky Flats National Wildlife Refuge (NWR) (Unit 6), in Jefferson 
and Broomfield Counties, and noted that proposed critical habitat would 
include portions of DOE's Central Operable Unit (COU) of 1,300 ac (530 
ha), where a former facility processed and manufactured nuclear 
weapons. Many DOE operational maintenance and monitoring activities 
continue to take place within the COU under closure and cleanup 
agreements. The DOE urged the Service to exclude the COU from

[[Page 78437]]

designation of critical habitat within this unit because designation 
could adversely impact actions required under these agreements.
    Our Response: We have modified this final rule to more accurately 
reflect DOE presence on the Rocky Flats Site. The Rocky Flats Site 
(Unit 6) is managed by the Service (Rocky Flats NWR) and DOE (the 
Central Operating Unit and certain other lands). Buildings and other 
structures at the site have been decommissioned and demolished, and the 
disturbed areas have been restored, or are undergoing restoration. 
Clean-up and closure of the COU was completed in 2005. Many operational 
maintenance and monitoring activities continue to take place in the 
COU, to maintain the CERCLA (the Comprehensive Environmental Response, 
Compensation, and Liability Act, also known as Superfund, 42 U.S.C. 
9601 et seq.) and RCRA (Resource Conservation and Recovery Act, 42 
U.S.C. 6901 et seq.) remedies implemented in accordance with the Rocky 
Flats Management Agreement.
    The final Rocky Flats NWR Comprehensive Conservation Plan (CCP) was 
announced in the Federal Register on April 18, 2005 (70 FR 20164). The 
CCP outlines the management direction and strategies for NWR 
operations, habitat restoration, and visitor services, for a period of 
15 years. The CCP provides a vision for the NWR; guidance for 
management decisions; and the goals, objectives, and strategies to 
achieve the NWR's vision and purpose. One objective of the CCP is to 
protect, maintain, and improve approximately 1,000 ac (400 ha) of PMJM 
habitat on the NWR. A programmatic section 7 consultation with DOE for 
their cleanup and maintenance activities was completed in 2004 (Service 
2004c). This consultation addressed removal of manmade structures in 
and adjacent to PMJM habitat, and ongoing operations in the COU in 
support of the CERCLA/RCRA remedy.
    We invited information and comments on potential exclusion of the 
Rocky Flats Site in part because of the previous exclusion of the site 
from critical habitat in our June 23, 2003, final rule (68 FR 37275). 
That exclusion appeared at odds with the recent interpretation of 
critical habitat designation on Federal lands. Federal agencies have an 
affirmative conservation mandate under section 7(a)(1) of the Act to 
contribute to the conservation of listed species. On the Rocky Flats 
Site, as with other Federal lands, we anticipate that effective land 
management strategies can and will be employed by Federal agencies to 
conserve PMJM populations. We have determined that lands on the Rocky 
Flats Site are essential to the conservation of the species. 
Designation of critical habitat on the Rocky Flats Site highlights the 
importance of the area to the PMJM, while encouraging the NWR and DOE 
to provide a consistent and effective approach to conserve the PMJM. 
These lands require special management considerations or protection, as 
evidenced by and incorporated in management plans and the programmatic 
consultation referenced above. Potential effects to habitat on the site 
that may be addressed under programs, practices, and activities within 
the authority and jurisdiction of Federal land management agencies 
include, but are not limited to, weed management, wildland fire 
management, recreation, construction and maintenance of roads and 
trails, and operational maintenance and monitoring activities within 
the COU. For the above reasons, we conclude that the entire Rocky Flats 
site, including the COU, contains the physical and biological features 
essential to the conservation of the PMJM and merits designation as 
critical habitat.
    (28) Comment: One commenter requested that the easternmost portion 
of the Rocky Flats Site (Unit 6) in Jefferson and Broomfield Counties, 
the site of proposed roadway expansion along Indiana Street, be 
excluded from critical habitat, because it is planned for development. 
They cited the Rocky Flats National Wildlife Refuge Act of 2001, and 
Rocky Flats National Wildlife Refuge Comprehensive Conservation Plan 
and Environmental Impact Statement (CCP/EIS) as addressing the roadway 
expansion and anticipating its future construction in spite of 
potential PMJM presence. Two other commenters urged that the specific 
area in question be included in designated critical habitat.
    Our Response: The areas in question contain the physical and 
biological features essential to conservation of the PMJM and have not 
been excluded from critical habitat. Should project plans for the road 
expansion go forward, the Service has concluded that subsequent 
environmental review, including compliance with the Act, will be 
required of any future project proponent to address any impacts to the 
PMJM, its habitat, and designated critical habitat. The Service has 
made no conclusions as to how any transfer of Federal land or roadway 
expansion would affect the PMJM. The Service only found that transfer 
of a corridor up to 300-ft (92-m) wide would not adversely affect 
management of the NWR (Service 2004, p. 191).
    (29) Comment: Denver Water requested exclusion of their properties 
covered under the Denver Water HCP, provided maps of their properties, 
and pointed out apparent Service mapping errors.
    Our Response: The eight properties in question include a total of 
approximately 250 ac (113 ha) in 4 critical habitat units (Units 5, 7, 
9, and 10). We have excluded these properties from critical habitat 
designation under section 4(b)(2) of the Act (see the Exclusions 
section below), and corrected maps and acreages as appropriate.
    (30) Comment: Douglas County requested exclusion of non-Federal 
lands within Douglas County based on their 2006 HCP.
    Our Response: We have not excluded the non-Federal lands in Douglas 
County. On May 11, 2006, we issued a section 10 incidental take permit 
that covers the PMJM for the Douglas County HCP (Service 2006a). The 
Douglas County HCP addresses only specified activities conducted by 
Douglas County and the towns of Castle Rock and Parker, within Douglas 
County, Colorado, on private and other non-Federal lands within the 
RCZ, as mapped by Douglas County. Impacts to the RCZ associated with 
the covered activities are mitigated by the permanent protection of 
portions of the RCZ and the restoration of habitat from temporary 
impacts. Stream segments totaling 15 mi (24 km) in length and 1,132 ac 
(458 ha) of the RCZ have been permanently protected as part of the 
Douglas County HCP. Management plans exist or are in development for 
these protected properties (Dougherty 2009). The majority of proposed 
critical habitat in Units 8 and 9, and a small amount of non-Federal 
property in Unit 10 are within the boundaries of the Douglas County 
HCP.
    While the Douglas County HCP includes the extensive mapped RCZ that 
encompasses areas believed to support the PMJM, the plan does not 
provide a means by which habitat within these zones will be effectively 
managed into the future. Only about 5 percent of the lands within the 
RCZ are set aside for conservation under the plan. The vast majority of 
lands in the RCZ receive no specific protection under the HCP. 
Potential impacts to physical and biological features essential to the 
PMJM from entities other than Douglas County and the cities of Parker 
and Castle Rock, including those by private landowners, are not 
addressed in the plan.

[[Page 78438]]

    (31) Comment: One commenter proposed that we link the two subunits 
proposed in Unit 8 (Cherry Creek), Douglas County.
    Our Response: The Draft Plan calls for a medium recovery population 
in Lower South Platte--Cherry Creek HUC. Each of the two subunits 
appears large enough to support a medium recovery population. We 
determined that linking them was not appropriate, after considering the 
variable quality of intervening habitat on private lands and 
determining that a much larger critical habitat unit with more reaches 
in low-quality habitat would not provide additional benefit to the 
PMJM.
    (32) Comment: One commenter stated that we should limit the 
downstream extent of designated critical habitat along Plum Creek in 
Unit 9 (West Plum Creek), Douglas County, to the point of maximum 
reservoir storage under the U.S. Army Corps of Engineers' (Corps') 
Chatfield Reservoir Reauthorization Project preferred alternative 
(maximum storage at 5,444 feet (ft) (1,660 meters (m)) in elevation).
    Our Response: The reach in question is federally owned, has been 
documented to support the PMJM, and has PCEs of appropriate quantity 
and spatial arrangement to qualify as critical habitat. We have 
determined that Plum Creek downstream to Chatfield Reservoir contains 
the physical and biological features essential to the conservation of 
the PMJM, and we have identified no basis to exclude this area from 
critical habitat under section 4(b)(2) of the Act. Substantial planning 
has taken place to address potential impacts to the PMJM should the 
reservoir expansion proceed, in part because proposed expansion of 
reservoir storage capacity would impact existing critical habitat on 
the Upper South Platte River (Unit 10). While designation of critical 
habitat along Plum Creek will provide additional regulatory protection 
to PMJM habitat in the area, the project sponsors are developing 
alternatives to address impacts to designated critical habitat on Plum 
Creek should the planned project move forward.
    (33) Comment: One commenter stated that we should exclude the 
Penley Ranch property along Indian Creek, Unit 9 (West Plum Creek) from 
critical habitat, on the basis that trapping conducted in 2007 did not 
document the PMJM on the property and the Service agreed at the time 
the PMJM was ``not likely to be present'' on the site. The commenter 
further stated that if the property was not excluded, we should develop 
more appropriate (less extensive) site-specific boundaries of critical 
habitat on the site.
    Our Response: While the PMJM was not captured during the 2007 
trapping effort, habitat on the site appeared to support the physical 
and biological features essential to the conservation of the PMJM. We 
concurred in 2007 that the PMJM was not likely present and that a 
proposed rural residential development on the property would not be 
likely to adversely affect the PMJM. We stated that our concurrence was 
valid only for one year. The residential development proposed did not 
take place. Captures of the PMJM have occurred in areas of comparable 
or lower quality habitat downstream on Indian Creek. PCEs are present 
along this reach of Indian Creek. While no further trapping efforts 
have taken place, we believe that the PMJM likely uses the reach, at a 
minimum as a movement corridor, and may occupy portions of the 
property. We therefore conclude that this reach of Indian Creek is 
occupied and merits designation as critical habitat. Indian Creek on 
the Penley Ranch is within the RCZ established under the Douglas County 
HCP. Outward extent of critical habitat on the property is being 
designated consistent with the boundaries of the Douglas County RCZ 
(see the Delineation of Critical Habitat Boundaries section below). See 
also related comment 61 and our response.
    (34) Comment: One commenter stated that the upstream extent of 
critical habitat along Bear Creek in Unit 9 (West Plum Creek) should 
terminate at the Lake Waconda Dam, as the lake and Perry Park Golf 
Course create a barrier to PMJM movement, and any PMJM population 
upstream from the golf course is isolated.
    Our Response: After we considered the extent to which the dam, 
lake, adjacent golf course, and associated development form a barrier 
to PMJM movement up and down stream, and assessed the quantity and 
spatial arrangement of PCEs on the reach upstream of the lake, we 
elected to limit the upstream extent of designated critical habitat 
along Bear Creek to the base of the Lake Waconda Dam (see the Summary 
of Changes from the Proposed Rule section below). Based on review of 
aerial photographs, we determined that the area upstream of the dam 
does not contain the physical and biological features essential to the 
conservation of the PMJM in the necessary spatial arrangement and 
distribution.
    (35) Comment: One commenter suggested that we designate critical 
habitat to link all four proposed subunits of Unit 10 (Upper South 
Platte River), Jefferson and Douglas Counties, and also designate their 
tributaries as critical habitat.
    Our Response: The Service has determined that connecting these 
subunits to form one very large critical habitat unit is not necessary. 
Land ownership and land uses vary along the South Platte River and its 
tributaries. While areas designated as critical habitat largely consist 
of National Forest System lands, many of the intervening reaches do 
not. Quality of PMJM habitat is not consistent. Reaches of lesser 
quality that are not being designated as critical habitat generally 
correspond to those that are not federally owned. In addition, the 
large West Plum Creek Unit (Unit 9), which corresponds to a large 
recovery population required in the Draft Plan, is also being 
designated in the same HUC. Tributaries have been examined, and we are 
designating only those that we determined meet the definition of 
critical habitat based on occurrence of physical and biological 
features essential to the conservation of the PMJM and proximity to 
known PMJM occurrence. (See also our response to comment 6.)
    (36) Comment: One commenter requested that we exclude critical 
habitat in Teller County because no PMJM have been documented there.
    Our Response: The PMJM has been documented on Trout Creek, Unit 10 
(South Platte River), at or very near the Douglas County-Teller County 
line (Service 2010). Based on contiguous habitat along Trout Creek in 
Teller County, we are designating critical habitat upstream to 7,600 ft 
(2,300 m) in elevation. We believe that this elevation provides a 
reasonable estimate of the upstream extent of habitat likely to be 
occupied by the PMJM in this reach.
    (37) Comment: Two commenters requested exclusion of Unit 11 
(Monument Creek), El Paso County, from critical habitat based on 
potential economic impacts and because protections for the PMJM are 
already in place as a result of the 1998 listing and local limits on 
development.
    Our Response: Our DEA addressed the extent of economic impacts 
likely to occur in this unit as the result of critical habitat 
designation. The updated final economic analysis (FEA) (Industrial 
Economics 2010b) concludes that $10.4 million to $17.7 million in 
incremental impacts due to designation of critical habitat may occur in 
Unit 11 over the next 20 years, resulting almost entirely from 
increased costs associated with section 7 consultation on residential 
and commercial development. However, the FEA (Chapter 3) explains why 
these estimates may be higher than what will likely occur. Based on the 
results of the

[[Page 78439]]

FEA, we have not excluded any areas from designation of critical 
habitat based on economic impacts (see the Required Determinations 
section). Current protections afforded the PMJM by its threatened 
status under the Act and by local regulations have not protected the 
PMJM and its habitat from the cumulative impacts of development. 
Degradation of creeks and riparian vegetation in this unit from recent 
development and associated stormwater runoff presents an ongoing issue. 
This degradation and projected future development in the area indicate 
that the unit requires special management consideration and protection.
    (38) Comment: One commenter urged us not to exclude El Paso County 
from critical habitat based on any countywide HCP not finalized.
    Our Response: We have not excluded El Paso County from critical 
habitat. The county has been developing a countywide HCP for the PMJM 
in coordination with the Service for several years. A countywide plan 
would likely cover most or all of the area in critical habitat Unit 11 
(Monument Creek). When we proposed revised critical habitat, we 
anticipated that we would receive a draft HCP prior to final revised 
critical habitat designation. To date, we have not received a draft of 
an HCP for our review, nor do we have any assurance as to if, when, or 
in what form, any countywide HCP will be submitted, or whether an 
incidental take permit for the PMJM under section 10 would be issued. 
Since any potential El Paso County plan remains in its formative 
stages, we have no basis to address possible benefits of exclusion.
Other Comments
    (39) Comment: One commenter noted that we had no basis to revise 
the 2003 rule that designated critical habitat for the PMJM.
    Our Response: We stand by our determination that revising critical 
habitat for PMJM is appropriate. Based on our review of the June 23, 
2003, final rule to designate critical habitat for the PMJM (68 FR 
37275), we determined that it is necessary to revise critical habitat. 
Our review found that we excluded three counties from critical habitat 
based on countywide HCPs under development. The 2003 rule stated, ``If 
pending HCPs are not completed, we will determine whether areas 
designated in this final rule need further refinement'' (68 FR 37290). 
Seven years later, only one of the three counties excluded from 
critical habitat has completed an HCP, and coverage under the Douglas 
County HCP is limited to actions by three local governments. Therefore, 
the basis upon which these exclusions were made, that countywide HCPs 
would be completed in the near future, was faulty, and revision is 
appropriate.
    (40) Comment: Two commenters pointed out that our 2003 rule 
downplayed the value of critical habitat designation. One commenter 
stated critical habitat designation is unhelpful, duplicative, and 
unnecessary, and that it provides little additional value given that 
areas proposed are believed to be occupied and currently subject to 
section 7 review under the Act. Based on this, they contended that the 
value of including additional critical habitat through our revision was 
negligible.
    Our Response: Designation of critical habitat is mandated by the 
Act. The purpose of critical habitat designation is to contribute to 
the conservation of endangered and threatened species and the 
ecosystems upon which they depend. It alerts Federal agencies and the 
public to areas essential for the conservation of the species and 
provides the species added regulatory protection under section 7 of the 
Act when Federal actions occur. (See Benefits of Designating Critical 
Habitat, below.)
    (41) Comment: We received comments that critical habitat provides 
little additional protection for the PMJM over various layers of 
existing protections, including local land use regulations, and that 
this negates the need for critical habitat designation.
    Our Response: Protections under the Act, including those afforded 
by designation of critical habitat, for the listed SPR of the PMJM in 
Colorado are necessary in part because local regulations and 
conservation efforts have proven insufficient to conserve the species. 
Our July 10, 2008, final rule that refined the listing of the PMJM (73 
FR 39789) specifies over what portion of its range the subspecies is 
threatened.
    (42) Comment: One commenter stated that designation of critical 
habitat should be limited to Federal lands.
    Our Response: As defined, critical habitat is not limited by land 
ownership, but rather based on areas essential to the conservation of 
the species and in need of special management or protection. Federally 
owned lands are more likely to contribute to conservation of the PMJM 
than private lands that are not subject to the Act's affirmative 
conservation mandate of 7(a)(1), which imposes on Federal agencies a 
duty to conserve listed species. Therefore, we prioritized the 
inclusion of Federal lands when deciding what quantity and distribution 
of lands containing the physical and biological features essential to 
the conservation of the PMJM are necessary. However, even with this 
prioritization, the amount of Federal lands alone is insufficient to 
provide for the conservation of the PMJM, as these lands are limited in 
geographic location, size, and habitat quality within Colorado. We are 
designating both Federal lands and non-Federal land as critical habitat 
where they meet the definition of critical habitat.
    (43) Comment: One commenter urged us not to exempt HCPs from 
critical habitat, based on the contentions that their purpose differs 
from that of critical habitat and that HCPs are less protective. The 
commenter suggested that the Service should conduct a detailed analysis 
of past protection of the PMJM afforded by HCPs, as opposed to that 
afforded by critical habitat designation, including the degree of 
habitat loss and take of the PMJM. The commenter added that exclusions 
based on HCPs would fragment habitat corridors otherwise designated as 
critical habitat.
    Our Response: Critical habitat and HCPs differ in their purpose, 
but both have a similar role in conservation of the species. In 
general, critical habitat designation affords an added layer of 
regulatory protection with regard to Federal actions, while an HCP 
provides a mechanism to permit take caused by non-Federal entities. We 
exclude areas covered by HCPs from critical habitat when the benefits 
of exclusion are greater than the benefits of inclusion. As part of 
this determination, we analyzed whether the HCP in place affords equal 
or greater conservation of the species than critical habitat 
designation would afford. These HCPs were developed to address the 
conservation needs of the PMJM and maintain its habitat. Issuance of 
associated section 10 permits by the Service required section 7 
consultations. Exclusion of these HCPs is not expected to affect 
movement corridors, because the HCPs were developed in coordination 
with the Service and address the conservation requirements of the PMJM.
    (44) Comment: One commenter believed that, at a minimum, all 
habitat occupied by PMJM should be designated as critical habitat, and 
called on us to provide a rationale for any occupied areas not 
designated.
    Our Response: The Act does not require that we designate critical 
habitat on all lands occupied by the species. We used the best 
scientific and commercial data available in our determination of this 
final designation of revised critical habitat. In addition, we 
considered peer review comments, public comments, and any additional 
information we

[[Page 78440]]

received. We determined a subset of all known occupied areas that 
contain PCEs is sufficient to provide for the conservation of the PMJM. 
This conclusion is based on the recommendations in the Draft Plan that 
a mix of small, medium, and large populations can conserve the species. 
We are designating all areas that we found to be essential.
    (45) Comment: One commenter stated that the Service must consider 
whether habitat outside that occupied by the listed entity is justified 
for designation as critical habitat and stated the opinion that 
occupied habitat in Wyoming must be considered for inclusion.
    Our Response: In accordance with section 3(5)(C) of the Act, not 
all areas that can be occupied by a species will be designated critical 
habitat. We designate as critical habitat areas outside the 
geographical area presently occupied by a listed species only when a 
designation limited to its present range would be inadequate to ensure 
the conservation of the species. Given the extent and distribution of 
known PMJM populations, we believe that protection within certain areas 
currently occupied will be sufficient to conserve the PMJM in Colorado, 
where the PMJM is listed under the Act.
    (46) Comment: One commenter suggested that we should conduct 
research to prove that the PMJM can live in all 418 mi of stream 
proposed as critical habitat.
    Our Response: We base our designation of critical habitat on the 
best scientific and commercial information available. The best 
information available to us indicates that the units we are designating 
as critical habitat are occupied. In addition, all PCEs upon which the 
PMJM depends are present within each unit of critical habitat. At any 
given site within a unit, one or more PCEs must be present for the site 
to qualify as critical habitat. For example, it may be determined that 
a reach qualifies as critical habitat based only on its ability to 
provide connectivity between more extensive habitat upstream and 
downstream. Determination of the limits of critical habitat at a 
specific site based on absence of any PCEs will be made by the Service 
on a site-by-site basis where needed.
    (47) Comment: One commenter noted the potential impact of critical 
habitat designation to grazing on Federal lands, which the commenter 
stated has been shown to be compatible with maintenance of PMJM 
populations.
    Our Response: The impact of the designation of critical habitat on 
Federal lands includes consultation under section 7 of the Act to 
determine if Federal actions would result in adverse modification of 
critical habitat. Where grazing is compatible with the maintenance and 
recovery of PMJM populations, we would determine that adverse 
modification would not be likely. Agriculture, including grazing, can 
be managed in many different ways, some of which may be beneficial to 
PMJM habitat, others harmful. Some PMJM habitat on Federal lands is 
currently grazed in a manner that appears to maintain good habitat for 
the PMJM. However, there may be areas managed in a manner that is not 
conducive to the development or maintenance of PMJM habitat. As 
defined, critical habitat is essential to conserve the species and may 
require special management considerations or protection. The areas 
designated as critical habitat have been determined to be essential to 
the conservation of the PMJM. During consultation required under 
section 7 of the Act, grazing practices on these areas would receive 
increased scrutiny by Federal land managing agencies and the Service. 
In those areas where current management results in maintenance of good 
PMJM habitat, there is a need to continue such practices, so future 
management considerations or protections may be required. In other 
instances, protections of designated critical habitat would help ensure 
that livestock management practices potentially harmful to the 
conservation of PMJM are not conducted without required consultation.
    (48) Comment: One commenter stated that based on any future change 
to our definition of ``adverse modification,'' third parties may mount 
legal challenges to Service consultations under section 7 of the Act 
and HCPs that address critical habitat.
    Our Response: Section 7(a)(2) of the Act requires Federal agencies, 
including the Service, to ensure that actions they fund, authorize, or 
carry out are not likely to destroy or adversely modify critical 
habitat. Decisions by the Fifth and Ninth Circuits Court of Appeals 
have invalidated our definition of destruction or adverse modification 
(50 CFR 402.02) (see Gifford Pinchot Task Force v. U.S. Fish and 
Wildlife Service, 378 F.3d 1059 (9th Cir. 2004) and Sierra Club v. U.S. 
Fish and Wildlife Service et al., 245 F.3d 434, 442 (5th Cir. 2001)), 
and we do not rely on this regulatory definition when we analyze 
whether an action is likely to destroy or adversely modify critical 
habitat. In response to these decisions, we are reviewing the 
regulatory definition of adverse modification in relation to 
conservation. We cannot speculate about future change to the definition 
of adverse modification, how it may impact conservation of the PMJM, or 
litigation that could follow. Threat of future lawsuits should not 
influence our designation of appropriate critical habitat.
Comments on Economic Analysis and Environmental Assessment
    (49) Comment: One commenter stated that providing only a 
``revision'' of our 2003 economic analysis and environmental 
assessment, alluded to in our revised critical habitat proposal, is 
insufficient and circumvents NEPA.
    Our Response: The DEA and NEPA analysis that we conducted for the 
2009 proposed rule updated our 2003 analysis. Our FEA and final 
environmental assessment differ substantially from documents produced 
in support of our 2003 designation of critical habitat. As all address 
designation of critical habitat for the PMJM, there are similarities.
    (50) Comment: One commenter indicated that the DEA underestimated 
the actual costs of critical habitat designation by applying an 
incremental approach to identify only those impacts attributable solely 
to the proposed rule. Because the SPR in Colorado, where the PMJM is 
listed, lies within the U.S. Tenth Circuit Court of Appeals, its ruling 
in New Mexico Cattle Growers Association v. United States Fish and 
Wildlife Service, 248 F.3d 1277 (10th Cir. 2001) should be followed. In 
this case, the court instructed the Service to conduct a full analysis 
of the economic impacts of proposed critical habitat, regardless of 
whether those impacts are attributable co-extensively to other causes.
    Our Response: The economic analysis estimates the total cost of 
species conservation activities, without subtracting the impact of pre-
existing baseline regulations (i.e., the cost estimates are fully co-
extensive). In addition, the economic analysis breaks the costs down 
into the baseline costs of all conservation activities resulting from 
the listing of PMJM under the Act, and the incremental costs of 
designation of critical habitat, which are above and additional to the 
baseline costs. We considered both the coextensive as well as the 
incremental costs when performing the 4(b)(2) exclusion analysis. In 
2001, the U.S. 10th Circuit Court of Appeals instructed the Service to 
conduct a full analysis of all of the economic impacts of proposed 
critical habitat designation, regardless of whether those impacts are 
attributable co-extensively to other causes (New

[[Page 78441]]

Mexico Cattle Growers Ass'n v. USFWS, 248 F.3d 1277 (10th Cir. 2001)). 
The economic analysis for the PMJM complies with direction from the 
U.S. 10th Circuit Court of Appeals.
    In developing this final rule, we considered our February 12, 2008, 
Draft Critical Habitat Exclusions Guidance. This guidance was developed 
by the Service in response to critical habitat case law, which 
documents the Courts' interpretations of the requirements of the Act. 
This rule is also consistent with the October 3, 2008, opinion from the 
Solicitor titled, ``The Secretary's Authority to Exclude Areas from a 
Critical Habitat Designation under Section 4(b)(2) of the Endangered 
Species Act.''
    In this rule, the Service declines to exercise its discretion to 
exclude any areas based on co-extensive or incremental impacts in this 
rule. Two courts have found the Secretary's decision not to exclude is 
completely within the Service's discretion and is not reviewable by a 
court (Home Builders Association of Northern California v. U.S. Fish & 
Wildlife Serv., 2006 U.S. Dist. Lexis 80255, *66 (E.D. Cal. 2006), 
reconsideration granted in part on other grounds, 2007 U.S. Dist. Lexis 
5208 (Jan. 24, 2007); Cape Hatteras Access Preservation Alliance v. 
DOI, 2010 U.S. Dist. Lexis 84515 (D.D.C. Aug. 17, 2010).
    (51) Comment: One commenter stated that the Service has not 
adequately quantified and analyzed the myriad potential economic 
benefits of critical habitat designation.
    Our Response: The purpose of critical habitat is to support the 
conservation of the PMJM. Quantification and monetization of species' 
conservation benefits requires information on the incremental change in 
the probability of PMJM conservation that is expected to result from 
the designation. No studies exist that provide such information for 
this species. Even if this information existed, the published valuation 
literature does not support the monetization of incremental changes in 
conservation probability for this species. Therefore, the primary 
benefits of this rule cannot be quantified or monetized based on the 
best, readily available scientific and economic information. Depending 
on the project modifications ultimately implemented as a result of the 
regulation, other ancillary benefits that are not the stated objective 
of critical habitat may also be achieved. Chapter 9 of the DEA 
describes the categories of potential benefits, including improvements 
in the value of adjacent or proximate properties, improvements in water 
quality, aesthetic benefits, increased recreational opportunities, 
increased regional expenditures and employment resulting from increased 
visitation to the region, and educational benefits. Because these 
categories of benefits are not the primary intention of the rule, and 
quantification and monetization of these benefits would require 
significant effort and provide limited value to the Service's decision-
making process, we provide only a qualitative discussion of these 
potential benefits.
    (52) Comment: One commenter stated that the DEA underestimates the 
potential impacts in Unit 11 (Monument Creek), El Paso County, by 
excluding from analysis the following types of parcels not likely to 
require a section 7 consultation: (1) Those parcels under county or 
government ownership; (2) those parcels occupied by existing buildings; 
and (3) those parcels under 100 ac (40 ha) in area. Further, the 
commenter stated that this assumption is inconsistent with other 
conclusions reached by the DEA, where: (1) The costs to small 
governmental jurisdictions are analyzed and estimated in the initial 
regulatory flexibility analysis (IRFA), (2) cost impacts to parcels 
occupied by existing buildings as a result of building maintenance 
activities are considered, and (3) parcels under 100 ac (40 ha) have 
undergone section 7 consultations for PMJM.
    Our Response: In section 3.6 of the DEA, the Service acknowledges 
that those parcels removed from further consideration could eventually 
be developed in such a way that would require a Federal permit or 
funding, resulting in a section 7 consultation and mitigation. However, 
the DEA focuses on estimating the potential economic impacts to new 
residential and commercial development on readily developable, private, 
and large open parcels of land. As evidenced by the Service's 
consultation history for the PMJM, such parcels are more likely to have 
a Federal nexus and undergo a section 7 consultation. As a result, 
parcels under government ownership were removed from further 
consideration. In Chapter 4 and Appendix A, the DEA estimates the 
impacts to governmental entities, including those that are small, and 
that are associated with other activities, namely road/bridge, utility, 
and bank stabilization construction and maintenance. These activities 
do not necessarily occur on parcels of land owned by the government.
    With respect to maintenance activities at existing buildings, the 
Service's consultation history does not suggest such activity requires 
consultation for the PMJM. However, the Service recognizes that large 
parcels with existing buildings could eventually be redeveloped (e.g., 
large ranch parcels), and therefore these parcels were analyzed in 
Chapter 3 of the FEA. Finally, parcels under 100 ac (40 ha) in size 
were removed from further consideration in the analysis, because the 
smallest residential development project that required a formal section 
7 consultation since 2003 was 173 units on a 107-ac parcel (Struthers 
Ranch). The Service's consultation record demonstrates that projects 
under 100 ac (40 ha) typically undergo informal section 7 consultations 
and technical assistance with the Service. In section 3.3.2, the DEA 
estimates the costs for these types of consultations.
    (53) Comment: One commenter indicated that the DEA underestimates 
the true economic impact of the proposed rule on the residential sector 
by not considering the impacts to the local, State, and national 
economy.
    Our Response: In section 3.5, the DEA estimates the regional 
economic impacts that may result from a potential reduction in 
residential home construction in Douglas and El Paso Counties due to 
the critical habitat designation. These regional impacts include 
estimates of the indirect (changes in output industries that supply 
goods and services to those directly affected), induced effects 
(changes in household consumption resulting from a change in 
employment), and job loss. To assess the potential impact of the 
proposed rule on the national economy, the FEA considers estimating the 
social welfare losses that result from changes in the price and 
quantity of available housing. However, such an analysis could not be 
conducted due to insufficient information to reliably model the markets 
for housing in areas affected by critical habitat. We assume these 
costs are in addition to the compliance costs incurred by developers or 
existing landowners or both.
    (54) Comment: One commenter indicated that the DEA does not include 
consultation costs for 15 road, bridge, utility, and bank stabilization 
projects that may not be covered by the existing Douglas County HCP. If 
these projects occur outside of the RCZ established by the HCP, the 
commenter indicated that they would incur these costs in full 
(estimated $60,000 to $150,000), rather than just the incremental costs 
estimated in the DEA.
    Our Response: As described in section 4 of the DEA, the projected 
number of road, bridge, utility, and bank stabilization projects 
potentially

[[Page 78442]]

impacted by the designation of critical habitat is based on estimates 
provided by the Colorado Department of Transportation and the 
consultation history provided by the Corps. Using this information, the 
DEA projects between approximately 21 and 24 formal consultations 
associated with these activities in Douglas County over the next 20 
years. Because there was no available information that indicated 
specifically whether these projects would occur inside or outside the 
RCZ, the analysis calculates and applies unit-specific, area-based 
factors to estimate the probability that projects would occur outside 
the RCZ and within critical habitat, and would therefore require 
consultation as a result of the designation (see pages 2-15 through 2-
17 of the DEA). For Douglas County, these factors are between 6 and 16 
percent. Using this methodology, we estimate in the DEA that the total 
incremental consultation cost (undiscounted) for the 21 to 24 projects 
ranges between $119,000 and $135,000.
    (55) Comment: Douglas County commented that the DEA does not 
account for the costs to purchase additional mitigation lands in 
Douglas County to support their HCP. Mitigation beyond that already 
established by the Douglas County HCP may be required for activities 
that occur in critical habitat. These costs could be significantly 
higher because the mitigation land already banked under the HCP would 
be exhausted more rapidly, the banked mitigation lands are unevenly 
distributed across critical habitat units, and land must be purchased 
in large blocks to acquire a relatively small percentage of PMJM 
habitat.
    Our Response: As described in section 4.2.3 of the DEA, the 
estimated cost of mitigation ranges from $3,580 to $35,800 per ac. The 
Service believes this tenfold range in unit costs is likely sufficient 
to cover the costs of additional mitigation land purchases that may 
result from designation of critical habitat in Douglas County. Since we 
have adopted the RCZ developed for the Douglas County HCP as the 
outward extent of critical habitat, additional mitigation required for 
projects covered by the HCP is not likely to increase greatly in 
extent. Measures to offset impacts to critical habitat may be 
restricted to the same unit where impacts occur. Exhibit 3-13 of the 
DEA provides an assessment of the quantity of land available for 
mitigation within each unit.
    (56) Comment: One commenter indicated that the DEA does not 
estimate a cost associated with the regulatory uncertainty created by 
the critical habitat label for the City of Greeley's proposed expansion 
at the Milton Seaman Reservoir.
    Our Response: Because of data limitations, as well as factors other 
than the designation of critical habitat (such as political, financial, 
and general environmental impacts) that will influence the outcome of 
the proposed expansion project at the Milton Seaman Reservoir, the 
costs associated with regulatory uncertainty attributable to the 
presence of the PMJM or its designated critical habitat are difficult 
to quantify. As described in section 5.3.3 of the DEA, a representative 
of the Corps suggested that the cost to the City of Greeley to pursue 
an offsite alternative to the preferred Milton Seaman Reservoir project 
may be as much as three to eight times higher than that of the 
expansion project that is currently contemplated. This range of 
increased costs was provided by the Corps, based on their rough 
estimate of the costs to develop water supply (on a per ac-ft basis) in 
the study area. It was not intended to be used to quantify the cost 
impacts of regulation uncertainty due to critical habitat designation, 
but rather to qualitatively characterize the relative costs of water 
supply development alternatives. However, we address this issue further 
in our FEA, and our discussion of the proposed Milton Seaman Reservoir 
in comment 24, above.
    (57) Comment: One commenter indicated that the DEA did not 
calculate the economic impact to the proposed Penley Reservoir (Unit 9) 
in Douglas County.
    Our Response: The economic analysis focuses on an estimate of 
impacts to economic activities that are reasonably foreseeable. The DEA 
did not consider potential impacts to the Penley Reservoir because the 
project is in the very early stages of planning. Due to insufficient 
information about this project, and considerable uncertainty as to 
whether it will be constructed within the next 20 years, the FEA does 
not quantify the potential impacts to this project, but does 
acknowledge it as potentially affected by the designation.
    (58) Comment: One commenter indicated that the DEA does not take 
into account the full range of activities required as part of the 
CERCLA and RCRA remedy for the DOE's COU on the Rocky Flats Site (Unit 
6), Jefferson and Broomfield counties, and the costs to revise or 
develop a new programmatic biological assessment and an accompanying 
biological opinion.
    Our Response: The FEA includes an extended list of the ongoing 
maintenance and monitoring activities required as part of the CERCLA/
RCRA remedy for the COU. Costs to the DOE to initiate one new 
programmatic consultation with the Service to cover all of these 
recurring remedial activities within critical habitat are estimated in 
section 7.2.1.
    (59) Comment: One commenter indicated that the DEA should recognize 
that the management and operations of the COU and Rocky Flats NWR areas 
on the Rocky Flats Site are conducted by two different Federal agencies 
with different and distinct regulatory requirements and objectives.
    Our Response: In our FEA, we have revised section 7 to clarify and 
distinguish the respective management and operation of the two areas by 
the DOE Office of Legacy Management and the Service.
    (60) Comment: Some commenters questioned the adequacy of the draft 
environmental assessment. Commenters either suggested that analysis of 
a wider range of alternatives was required or suggested detailed 
analysis of a specific alternative. Suggested alternatives included 
designation as critical habitat on all habitat occupied by the PMJM, 
designation of critical habitat consistent with all recovery 
populations called for in the Draft Plan, and designation of lesser 
amounts of critical habitat than proposed in our action alternative.
    Our Response: Designation as critical habitat of all habitat 
occupied by the PMJM, and designation of critical habitat consistent 
with recovery populations called for in the Draft Plan, were 
alternatives considered but not fully evaluated in the draft 
environmental assessment. In the first case, based on the Draft Plan, 
our professional judgment, and the best science available, we 
determined that only a subset of all occupied habitat was required for 
conservation of the PMJM. As explained in our July 10, 2008, rule to 
specify over what portion of its range the PMJM is threatened (73 FR 
39789), listing under the Act is largely based on widespread threats to 
PMJM's habitat from current and future human development. Current 
populations and distribution of PMJM are more than sufficient to 
maintain the species if threats are successfully addressed. Protecting 
all existing PMJM populations and their supporting habitat from 
development into the future is not required to conserve the species. In 
the second case, recovery populations specified in the Draft Plan do 
not necessarily equate to specific areas that meet the definition of 
critical habitat. For example, many proposed recovery populations were 
identified by HUC,

[[Page 78443]]

but not tied to a specific location. Recovery populations were also 
assigned to HUCs where the PMJM has not yet been verified as present. 
Insufficient information on PMJM presence and distribution is available 
to support designation of critical habitat in all HUCs addressed in the 
Draft Plan. See also our response to comments 10 and 11.
    (61) Comment: One commenter believed that the proposed action 
merits an environmental impact statement (EIS).
    Our Response: An EIS is required only in instances where a major 
Federal action is expected to have a significant impact on the human 
environment. Based on our draft environmental assessment, DEA, and the 
comments we received from the public, we prepared a final environmental 
assessment and determined that revised critical habitat for the PMJM 
does not constitute a major Federal action expected to have a 
significant impact on the human environment. That determination is 
documented in our Finding of No Significant Impact (FONSI). The final 
environmental assessment, FEA, and FONSI provide our rationale for our 
determination that this revised critical habitat designation will not 
have a significant impact on the human environment.
    (62) Comment: One commenter urged us to address an alternative 
consistent with the use of the Douglas County RCZ boundaries as the 
outward extent of designated critical habitat in our environmental 
assessment.
    Our Response: Our final environmental assessment addresses the RCZ 
boundaries as part of the preferred alternative. RCZ boundaries 
encompass slightly less area but more accurately define appropriate 
limits of critical habitat. The effects of using RCZ boundaries on 
three critical habitat units where such boundaries occur differ 
negligibly from effects of the action alternative in our draft 
environmental assessment.
    (63) Comment: One commenter stated that under the NEPA cumulative 
impacts analysis, the Service should include effects from past 
permitted take of the PMJM.
    Our Response: Under NEPA, cumulative impacts are impacts to the 
environment that result from the incremental effects of the action in 
question when added to past, present, and reasonably foreseeable future 
actions. Designation of revised critical habitat does not result in 
take of the PMJM, so evaluation of past, present, and future take is 
not required in our environmental assessment. Section 7 consultations 
involving the PMJM and its critical habitat will evaluate past impact 
and future take during the consultation process.

Summary of Changes From the Proposed Rule

    Our final designation of revised critical habitat for the PMJM 
results in a decrease of 7 mi (11 km) of rivers and streams and a 
decrease of 4,207 ac (1,702 ha) of land area from what we proposed in 
our October 8, 2009, proposed rule to revise the designation of 
critical habitat (74 FR 52066). The following changes account for the 
difference.
    (1) The areas designated as critical habitat in Units 1, 5, 7, 9, 
10, and 11 have changed from those areas proposed. We excluded portions 
of these units from the final designation of critical habitat, because 
we believe that the benefits of excluding these specific areas from the 
designation outweigh the benefits of including these areas. We have 
also concluded that the exclusion of these areas from the final 
designation of critical habitat will not result in the extinction of 
the PMJM. These exclusions are discussed in detail in the Exclusions 
section below.
    (2) In Unit 9 in Douglas County, we have reduced the extent of 
designated critical habitat from that proposed on Bear Creek, a 
tributary to West Plum Creek. The upstream terminus of designated 
critical habitat is located at the base of the Waconda Lake Dam, 
because Waconda Lake and surrounding development present a barrier to 
PMJM movement along Bear Creek.
    (3) We have determined that it is appropriate to use boundaries of 
the RCZ mapped by Douglas County for their HCP as the outward boundary 
of revised critical habitat in portions of Units 8, 9, and 10. See the 
Delineation of Critical Habitat Boundaries section below for a 
discussion of this change.
    (4) Area totals within various units have been recalculated. Area 
totals described in the proposed rule for various units included slight 
inaccuracies, which resulted from the GIS methodology that counted 
overlapping stream segments twice. Therefore, the area within some 
units has decreased.
    (5) We agreed to modify the outward boundaries of proposed critical 
habitat within Douglas County's mapped RCZ boundaries (see the 
Delineation of Critical Habitat Boundaries section), as the RCZ 
represents a site-specific mapping of PMJM habitat boundaries.

Critical Habitat

    Critical habitat is defined in section 3 of the Act as:
    (1) The specific areas within the geographical area occupied by the 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features
    (a) Essential to the conservation of the species, and
    (b) Which may require special management considerations or 
protection; and
    (2) Specific areas outside the geographical area occupied by the 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Conservation, as defined under section 3 of the Act, means the use 
of all methods and procedures that are necessary to bring any 
endangered or threatened species to the point at which the measures 
provided under the Act are no longer necessary. Such methods and 
procedures include, but are not limited to, all activities associated 
with scientific resources management, such as research, census, law 
enforcement, habitat acquisition and maintenance, propagation, live 
trapping, transplantation, and, in the extraordinary case where 
population pressures within a given ecosystem cannot otherwise be 
relieved, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the prohibition against Federal agencies carrying out, funding, 
or authorizing activities that are likely to result in the destruction 
or adverse modification of critical habitat. Section 7(a)(2) of the Act 
requires consultation on Federal actions that may affect critical 
habitat. The designation of critical habitat does not affect land 
ownership or establish a refuge, wilderness, reserve, preserve, or 
other conservation area. Such designation does not allow the government 
or public to access private lands. Such designation does not require 
implementation of restoration, recovery, or enhancement measures by 
non-Federal landowners. Where a landowner seeks or requests Federal 
agency funding or authorization for an action that may affect a listed 
species or critical habitat, the consultation requirements of section 
7(a)(2) of the Act would apply, but even in the event of a destruction 
or adverse modification finding, the Federal action agency's and the 
applicant's obligation is not to restore or recover the species, but to 
implement reasonable and prudent

[[Page 78444]]

alternatives to avoid destruction or adverse modification of critical 
habitat.
    For inclusion in a critical habitat designation, the habitat within 
the geographical area occupied by the species at the time of listing 
must contain physical and biological features that are essential to the 
conservation of the species, and be included only if those features may 
require special management considerations or protection. Critical 
habitat designations identify, to the extent known using the best 
scientific and commercial data available, habitat areas supporting the 
essential physical or biological features that provide essential life 
cycle needs of the species; that is, areas on which are found the 
physical or biological features laid out in the appropriate quantity 
and spatial arrangement for the conservation of the species. Under the 
Act and regulations at 50 CFR 424.12, we can designate critical habitat 
in areas outside the geographical area occupied by the species at the 
time it is listed only when we determine those areas are essential for 
the conservation of the species and that designation limited to those 
areas occupied at the time of listing would be inadequate to ensure the 
conservation of the species. When the best available scientific data do 
not demonstrate that the conservation needs of the species require such 
additional areas, we will not designate critical habitat in areas 
outside the geographical area occupied by the species at the time of 
listing. An area currently occupied by the species but that was not 
occupied at the time of listing may, however, be essential to the 
conservation of the species and may be included in the critical habitat 
designation.
    Section 4 of the Act requires that we designate critical habitat on 
the basis of the best scientific and commercial data available. 
Further, our Policy on Information Standards Under the Endangered 
Species Act (published in the Federal Register on July 1, 1994 (59 FR 
34271)), the Information Quality Act (section 515 of the Treasury and 
General Government Appropriations Act for Fiscal Year 2001 (Pub. L. 
106-554; H.R. 5658)), and our associated Information Quality Guidelines 
provide criteria, establish procedures, and provide guidance to ensure 
that our decisions are based on the best scientific data available. 
They require our biologists, to the extent consistent with the Act and 
with the use of the best scientific data available, to use primary and 
original sources of information as the basis for recommendations to 
designate critical habitat.
    When we are determining which areas should be designated as 
critical habitat, our primary source of information is generally the 
information developed during the listing process for the species. 
Additional information sources may include the recovery plan for the 
species, articles in peer-reviewed journals, conservation plans 
developed by States and counties, scientific status surveys and 
studies, biological assessments, or other unpublished materials and 
expert opinion or personal knowledge. Substantive comments we receive 
in response to proposed critical habitat designations are also 
considered.
    Habitat is often dynamic, and species may move from one area to 
another over time. Furthermore, we recognize that critical habitat is 
designated at a particular point in time; with changes in the future, 
we may find that the designation no longer includes all of the habitat 
areas necessary for the recovery of the species to respond to these 
changes. For these reasons, a critical habitat designation does not 
signal habitat outside the designated area is unimportant or may not be 
required for recovery of the species.
    Areas that support occurrences, but are outside the critical 
habitat designation, will continue to be subject to conservation 
actions we and other Federal agencies implement under section 7(a)(1) 
of the Act. They are also subject to the regulatory protections 
afforded by the section 7(a)(2) jeopardy standard, as determined on the 
basis of the best available scientific information at the time of the 
agency action. Federally funded or permitted projects affecting listed 
species outside their designated critical habitat areas may still 
result in jeopardy findings in some cases. Similarly, critical habitat 
designations made on the basis of the best available information at the 
time of designation will not control the direction and substance of 
future recovery plans, HCPs, or other species conservation planning 
efforts if new information available to these planning efforts calls 
for a different outcome.

Climate Change

    According to the Intergovernmental Panel on Climate Change (IPCC), 
``Warming of the climate system in recent decades is unequivocal, as is 
now evident from observations of increases in global average air and 
ocean temperatures, widespread melting of snow and ice, and rising 
global sea level'' (IPCC 2007, p. 1). Climate change will be a 
particular challenge for biodiversity because the interaction of 
additional stressors associated with climate change and current 
stressors may push species beyond their ability to survive (Lovejoy and 
Hannah 2005, pp. 325-326). The synergistic implications of climate 
change and habitat fragmentation are the most threatening aspect of 
climate change for biodiversity (Hannah et al. 2005, p. 4).
    For the southwestern region of the United States, which includes 
Colorado, warming is occurring more rapidly than elsewhere in the 
country (Karl et al. 2009, p. 129). In Colorado, Statewide temperatures 
have increased 2 [deg]F (3.6 [deg]C) over the past 30 years, but high 
variability in annual precipitation precludes the detection of long-
term trends (Ray et al. 2008, p. 5).
    While there is uncertainty about the exact nature and severity of 
climate change-related impacts anticipated within the Colorado range of 
the PMJM, a trend of climate change in the mountains of western North 
America is expected to decrease snowpack, hasten spring runoff, and 
reduce summer flows (IPCC 2007, p. 11). This could impact the PMJM 
habitat in a variety of direct and indirect ways. With increases in 
temperature, species' ranges are likely to move higher in elevation and 
northward (Karl et al. 2009, p. 132). Changes could cause a greater 
PMJM dependence on higher elevation, cooler, and potentially moister 
areas for survival in Colorado. The highest elevation at which the PMJM 
has been documented in Colorado is approximately 7,600 ft (2,317 m) 
(Service 2010). The preponderance of lands near to or higher than this 
elevation in the Colorado Front Range are in Federal ownership and are 
likely subject to fewer threats from human development than non-Federal 
lands. These Federal lands may serve as an important refuge should PMJM 
populations shift higher into the mountains.
    Changes in stream flow intensity and timing may affect riparian 
habitats on which the PMJM depends. For example, earlier runoff could 
impact the smaller high-elevation streams within the upper reaches of 
drainages, which are maintained primarily by melted snow. Reduced or no 
flow during summer and fall could make these streams less hospitable to 
the PMJM and limit their seasonal use. Changes in timing and amount of 
runoff may also influence human diversion, storage, and conveyance of 
water (Ray et al. 2008, p. 41), which in turn could impact riparian 
habitats required by the PMJM.

Primary Constituent Elements

    In accordance with section 3(5)(A)(i) of the Act and the 
regulations at 50 CFR 424.12(b), in determining which areas occupied at 
the time of listing to designate as critical habitat, we consider

[[Page 78445]]

the physical and biological features that are essential to the 
conservation of the species and that may require special management 
considerations or protection. These features are the primary 
constituent elements (PCEs), laid out in the appropriate quantity and 
spatial arrangement for conservation of the species. In general, 
physical and biological factors include, but are not limited to:
    (1) Space for individual and population growth and for normal 
behavior;
    (2) Food, water, air, light, minerals, or other nutritional or 
physiological requirements;
    (3) Cover or shelter;
    (4) Sites for breeding, reproduction, or rearing (or development) 
of offspring; and
    (5) Habitats that are protected from disturbance or are 
representative of the historic, geographical, and ecological 
distributions of a species.
    We derive the PCEs required for the PMJM from its biological needs. 
The areas included in this revised critical habitat designation for the 
species contain the essential features to fulfill the species life-
history requirements. The PCEs and the resulting physical and 
biological features essential to the conservation of the PMJM are 
derived from studies of this species' habitat, ecology, and life 
history as described in our proposed rule to revise the designation of 
critical habitat for the PMJM, published in the Federal Register 
October 8, 2009 (74 FR 52066).
    All units designated as critical habitat for the PMJM are currently 
believed to be occupied, are within the geographical area occupied by 
the species at the time of listing, and contain sufficient PCEs to 
support one or more life-history functions. Individual stream reaches 
within each unit contain at least one of the PCEs, and are either 
believed to be occupied by the PMJM, or provide crucial opportunities 
for connectivity to facilitate dispersal and genetic exchange within 
the unit.
    Based on our current knowledge of the life history, biology, and 
ecology of the PMJM, and the requirements of the habitat to sustain the 
essential life-history functions of the species, we have determined 
that the PCEs specific to the PMJM are:
    (1) Riparian corridors:
    (A) Formed and maintained by normal, dynamic, geomorphological, and 
hydrological processes that create and maintain river and stream 
channels, floodplains, and floodplain benches and that promote patterns 
of vegetation favorable to the PMJM;
    (B) Containing dense, riparian vegetation consisting of grasses, 
forbs, or shrubs, or any combination thereof, in areas along rivers and 
streams that normally provide open water through the PMJM's active 
season; and
    (C) Including specific movement corridors that provide connectivity 
between and within populations. This may include river and stream 
reaches with minimal vegetative cover or that are armored for erosion 
control; travel ways beneath bridges, through culverts, along canals 
and ditches; and other areas that have experienced substantial human 
alteration or disturbance.
    (2) Additional adjacent floodplain and upland habitat with limited 
human disturbance (including hayed fields, grazed pasture, other 
agricultural lands that are not plowed or disked regularly, areas that 
have been restored after past aggregate extraction, areas supporting 
recreational trails, and urban-wildland interfaces).
    Existing human-created features and structures within the 
boundaries of the mapped units, such as buildings, roads, parking lots, 
other paved areas, manicured lawns, other urban and suburban landscaped 
areas, regularly plowed or disked agricultural areas, and other 
features not containing any of the PCEs that support the PMJM, are not 
considered critical habitat.

Special Management Considerations or Protection

    When designating critical habitat, we assess whether the occupied 
areas contain the physical and biological features that are essential 
to the conservation of the species, and whether these features may 
require special management considerations or protection. Special 
management considerations or protection means any methods or procedures 
useful in protecting physical and biological features of the 
environment for the conservation of listed species. The areas we are 
designating as revised critical habitat will require some level of 
management to address the current and future threats to the physical 
and biological features essential to the conservation of the PMJM, and 
to ensure the recovery of the species. In all units, special management 
considerations or protection of the essential features may be required 
to provide for the sustained function of the riparian corridors on 
which the PMJM depends.
    The PMJM is closely associated with riparian ecosystems that are 
relatively narrow and represent a small percentage of the landscape. 
Our July 10, 2008, final rule for the PMJM to specify over what portion 
of its range the subspecies is threatened (73 FR 39789) concluded that 
the decline in the extent and quality of PMJM habitat is the main 
factor that threatens the subspecies. Special management considerations 
and protection may be required to address the threats of habitat 
alteration, degradation, loss, and fragmentation that results from 
urban development, flood control, water development, agriculture, and 
other human land uses that adversely impact PMJM populations. Habitat 
destruction may affect the PMJM directly or by destroying nest sites, 
food resources, and hibernation sites; by disrupting behavior; or by 
forming a barrier to movement.

Criteria Used To Identify Critical Habitat

    As required by section 4(b) of the Act, we used the best scientific 
and commercial data available to designate critical habitat. We are 
designating critical habitat in specific areas that include river and 
stream reaches, and their adjacent floodplains and uplands, that are 
within the known geographic and elevational range of the PMJM in the 
SPR in Colorado where it is listed and that contain the features 
essential to the conservation of the PMJM. All areas included in 
critical habitat contain at least one of the PCEs, and are currently 
occupied by the PMJM or provide crucial opportunities for connectivity 
to facilitate dispersal and genetic exchange.
    Our critical habitat designation identifies the appropriate 
quantity and spatial arrangement of the requisite PCEs that we have 
determined to be essential to the conservation of the subspecies. We 
determined that there are more areas currently occupied by the PMJM 
than are necessary to conserve the subspecies within the SPR in 
Colorado. We base this on the known occurrence and distribution of the 
PMJM (Service 2010) and upon the conservation strategy in the Draft 
Plan, which indicates that when specified criteria are met for a subset 
of existing populations throughout the range of the PMJM, the 
subspecies can be delisted (Service 2003a, p. 19). To recover the PMJM 
to the point where it can be delisted, the Draft Plan identifies the 
need for a specified number, size, and distribution of wild, self-
sustaining PMJM populations. On the basis of the above described 
criteria, we have chosen a subset of the areas occupied by the PMJM 
within the SPR in Colorado that have the physical and biological 
features essential to the PMJM for inclusion in critical habitat.

[[Page 78446]]

    We only consider including unoccupied areas within critical habitat 
designations if they are essential to the conservation of the species, 
and we determine that we cannot conserve the species by only including 
occupied areas in the critical habitat. Because we have determined that 
the conservation of the PMJM can be achieved through the designation of 
currently occupied lands, we find that no unoccupied areas are 
essential at this time. The subspecies was listed primarily due to the 
threat of impending development to the existing remaining habitat for 
the species within the Front Range of Colorado. We have determined that 
recovery of the subspecies can be achieved by protecting a subset of 
the currently occupied habitat from the threat of development. 
Recolonization of former parts of the range, while beneficial to the 
subspecies, is not currently believed to be necessary to conserve the 
PMJM in the long term.
    When determining critical habitat boundaries within this final 
rule, we made every effort to avoid including developed areas such as 
lands covered by buildings, pavement, and other structures because such 
lands lack PCEs for the PMJM. The scale of the maps we prepared under 
the parameters for publication within the Code of Federal Regulations 
may not reflect the exclusion of such developed lands. Any such lands 
inadvertently left inside critical habitat boundaries shown on the maps 
of this final rule have been excluded by text in the rule and are not 
designated as critical habitat. Therefore, a Federal action involving 
these lands will not trigger section 7 consultation with respect to 
critical habitat and the requirement of no adverse modification unless 
the specific action would affect the PCEs in the adjacent critical 
habitat.
Available Information
    Our June 23, 2003, final rule designating critical habitat for the 
PMJM (68 FR 37275) cited the March 11, 2003, Working Draft of a 
Recovery Plan for the PMJM, and the concepts described within (PMJM 
Recovery Team 2003), as a source of the best scientific and commercial 
data available on the PMJM. For designating revised critical habitat, 
we relied heavily on the information, concepts, and conservation 
recommendations contained in the Working Draft and the slightly 
modified Draft Plan (Service 2003a), as well as the current efforts of 
the recently formed Recovery Team. We used these as a starting point 
for identifying those areas for inclusion in critical habitat that 
contain the requisite PCEs in the appropriate quantity and spatial 
arrangement that are essential for the conservation of the PMJM. The 
Draft Plan is based on the work of scientists and stakeholders who met 
regularly over a period of more than 3 years. The plan was developed by 
incorporating principles of conservation biology and all available 
knowledge regarding the PMJM. Recovery Team meetings were open to the 
public, and drafts of the plan were discussed in public meetings held 
in Colorado and Wyoming. We forwarded a draft of the Draft Plan to 
species experts for review, and their comments (Armstrong 2003, pers. 
comm.; Hafner 2003, pers. comm.) were considered prior to the Draft 
Plan being made available on the Service Web site.
    We also have incorporated all new information received since 2003, 
including:
     Data in reports submitted by researchers holding recovery 
permits under section 10(a)(1)(A) of the Act;
     Research published in peer-reviewed articles and presented 
in academic theses, agency reports, and unpublished data; and
     Various Geographic Information System (GIS) data layers 
and cover type information, including land ownership information, 
topographic information, locations of the PMJM obtained from radio-
collars, and locations of the PMJM confirmed to the species level via 
deoxyribonucleic acid (DNA) analysis, morphological analysis, and other 
verified records.
We also received information from Federal, State, and local 
governmental agencies, and from academia and private organizations that 
have collected scientific data on the PMJM.
    The Draft Plan identifies specific criteria for reaching recovery 
and the delisting of the PMJM. An important change since our 2003 
designation of critical habitat was the 2008 final rule limiting the 
listing of the PMJM to the SPR in Colorado. The Draft Plan identified 
areas as necessary for recovery throughout the range of the PMJM, 
including areas in Wyoming where the PMJM was listed at the time. 
Identified areas within the SPR in Colorado were based on the best 
available information and continue to reflect our best judgment of what 
we believe to be necessary for recovery. While elements of the Draft 
Plan may change prior to finalization of a recovery plan, our review of 
the Draft Plan and the ongoing Recovery Team review leads us to 
conclude that the concepts described within it continue to represent 
the best scientific and commercial data available regarding steps 
needed for the recovery of the PMJM.
    The Draft Plan provides a review of conservation biology theory 
regarding population viability (Service 2003a, p. 21). To recover the 
PMJM to the point where it can be delisted, the Draft Plan identifies 
the need for a specified number, size, and distribution of wild, self-
sustaining PMJM populations across the known range of the PMJM. It 
defines large populations as maintaining 2,500 mice, and usually 
including at least 50 mi (80 km) of rivers and streams. It defines 
medium populations as maintaining 500 mice, and usually including at 
least 10 mi (16 km) of rivers and streams. The average number of PMJM 
per stream mile was derived from site-specific studies and used to 
approximate minimum occupied stream miles required to support recovery 
populations of appropriate size (Service 2003a, p. 21).
    The distribution of these recovery populations is intended both to 
reduce the risk of multiple PMJM populations being negatively affected 
by natural or manmade events at any one time, and to preserve the 
existing genetic variation within the PMJM. The Draft Plan states, 
``species well-distributed across their historical range are less 
susceptible to extinction and more likely to reach recovery than 
species confined to a small portion of their range.'' The document also 
states that ``spreading the recovery populations across hydrologic 
units throughout the range of the subspecies also preserves the 
greatest amount of the remaining genetic variation, and may provide 
some genetic security to the range-wide population'' (Service 2003a, p. 
20). The Draft Plan emphasizes the value of retaining disjunct or 
peripheral populations that may be important to recovery (Lomolino and 
Channell 1995, p. 481) and may have diverged genetically from more 
central populations due to isolation, genetic drift, and adaptation to 
local environments (Lesica and Allendorf 1995, pp. 754-755).
    While the Draft Plan addresses the entire range of the PMJM, the 
SPR in Colorado where the PMJM remains listed includes multiple 
subdrainages that are addressed individually in the Draft Plan (Figure 
1). Within Colorado, the Draft Plan identifies recovery criteria for 
the two major river drainages where the PMJM occurs (the South Platte 
River drainage and the Arkansas River drainage), and for each 
subdrainage judged likely to support the PMJM. In some cases, the Draft 
Plan identifies recovery criteria for subdrainages where limited 
trapping has not confirmed the presence of the PMJM. Boundaries of 
drainages and subdrainages have been mapped by the

[[Page 78447]]

USGS. For the Draft Plan, 8-digit hydrologic unit boundaries were 
selected to define subdrainages. A total of 13 HUCs in the SPR of PMJM 
in Colorado are identified in the Plan as occupied or potentially 
occupied by the PMJM. Ten are identified in the South Platte River 
drainage and three in the Arkansas River drainage.

BILLING CODE 4310-55-C
    One issue raised by the Recovery Team was whether the conservation 
strategy that specified the number, size, and distribution of PMJM 
recovery populations in Colorado remained valid despite the 2008 
removal of the Wyoming portion of PMJM's range from listing. In 
Colorado, the strategy has been to establish at least three large 
populations and three medium populations spread over six subdrainages. 
Recovery of the PMJM would require these populations to be protected 
from threats. Additionally, the Plan suggests establishing at least 
three small populations or one medium population in seven other 
subdrainages, if the PMJM is present. Another issue

[[Page 78448]]

raised was whether the strategy required modification based on DNA 
testing that revealed that the PMJM in northern and southern areas of 
the subspecies' range (Wyoming and Larimer County in Colorado vs. 
Douglas and El Paso Counties in Colorado) exhibited significant genetic 
differences (King et al. 2006, pp. 4337-4338). The Recovery Team 
concluded (Jackson 2009, pers. comm.) that the 2003 conservation 
strategy adequately addresses recovery across the PMJM's range in 
Colorado, and would maintain the genetic diversity reported by King et 
al. (2006).
Biological Factors
    Presence of the PMJM was determined based largely on the results of 
trapping surveys, the vast majority of which were conducted in the 12 
years since listing the PMJM under the Act. Consistent with our July 
10, 2008, final rule to amend the listing for the PMJM (73 FR 39789), 
subdrainages judged to be occupied by the PMJM in Colorado include 
those that: (1) Have recently been documented to support jumping mice 
identified by genetic or morphological examination as the PMJM; or (2) 
have recently been documented to support jumping mice not identified to 
the species level, but occurring at elevations below 6,700 ft (2,050 
m), where western jumping mice have infrequently been documented. In 
our July 17, 2002, proposal (67 FR 47154) and our June 23, 2003, 
designation of critical habitat (68 FR 37275), we summarized trapping 
results and means of positive identification for each unit. See our 
2003 rule designating critical habitat and our 2008 final rule to amend 
the listing for the PMJM for more information on our determinations 
regarding presence of the PMJM in various subdrainages.
    Boundaries of some critical habitat units extend beyond capture 
locations to include those reaches that we believe to be occupied by 
the PMJM, based on the best scientific data available regarding capture 
sites, the known mobility of the PMJM, and the quality and continuity 
of habitat components along stream reaches. Where appropriate, we 
include details on the known status of the PMJM within specific 
subdrainages in the ``Revised Critical Habitat Designation'' section of 
this rule.
    Despite numerous surveys, the PMJM has not been found in the Denver 
metropolitan area since well before its 1998 listing, and is believed 
to be extirpated from much of the Front Range urban corridor as a 
result of extensive urban development. The area does not support the 
spatial arrangement and quantity of requisite PCEs to support PMJM 
populations, and, as a consequence, we have determined that this area 
does not contain the features essential to the conservation of the 
species.
Additional Factors Considered
    Based on the Draft Plan, we believe that we can achieve 
conservation of the PMJM with only a subset of areas currently occupied 
or containing essential features. To identify the specific subset of 
areas for inclusion in critical habitat, we considered several 
qualitative criteria in addition to the presence of the PCEs. These 
criteria were used to judge the current status, conservation needs, and 
probable persistence of the essential features of PMJM populations in 
specific areas, and included: (1) The quality, continuity, and extent 
of habitat components present; (2) the presence of lands devoted to 
conservation (either public lands such as parks, wildlife management 
areas, and dedicated open space, or private lands under conservation 
easements); and (3) the landscape context of the site, including the 
overall degree of current human disturbance and presence, and 
likelihood of future development based on local planning and zoning.
    Where specific areas met the definition of critical habitat under 
section 3 of the Act (within the geographical area occupied by the 
species and containing features essential to the conservation of the 
species which may require special management considerations or 
protection) and other criteria were comparable, we evaluated land 
ownership as a selection criterion for inclusion in critical habitat. 
Consistent with the Draft Plan (Service 2003, p. 52), we first selected 
Federal lands where effective land management strategies can be 
employed by Federal agencies to conserve PMJM populations. Federal 
agencies already have an affirmative conservation mandate under the Act 
to contribute to the conservation of listed species. Therefore, we 
determined that federally owned lands are more likely to meet the 
requirements for recovery of the species than private lands that are 
not subject to the Act's affirmative conservation mandate. However, we 
cannot depend solely on federally owned lands for critical habitat, as 
these lands are limited in geographic location, size, and habitat 
quality within the SPR in Colorado where the PMJM is listed. In 
addition to the federally owned lands, we included some non-Federal 
public lands, including lands owned by the State of Colorado or by 
local governments, and some privately owned lands.
    This revised designation of critical habitat in Colorado consists 
of 11 units, 6 of which are designed to support three large and three 
medium PMJM recovery populations, corresponding to those designated in 
the Draft Plan. While the Draft Plan designates the approximate 
location of these large and medium recovery populations, it does not 
delineate specific boundaries.
    In addition, the Draft Plan establishes a goal of three small 
recovery populations (including at least 3 mi (5 km) of rivers or 
streams) or one medium recovery population in seven other HUCs within 
the PMJM's range in Colorado. The Draft Plan does not identify the 
locations of recovery populations within these remaining seven HUCs. It 
also provides an exception to the above goal; no recovery populations 
are required in those HUCs that, when adequately surveyed, are found to 
have no PMJM populations. In some HUCs, presence of the PMJM has not 
been confirmed and the quality, continuity, and extent of physical and 
biological features essential to the PMJM appear lacking. In others, 
insufficient surveys have been conducted to establish distribution of 
PMJM populations or to determine where recovery populations should be 
located. Due to insufficient information, we are unable to designate 
critical habitat units corresponding to Draft Plan requirements in all 
of these remaining seven HUCs.
    The Draft Plan anticipates that, in the future, the locations of 
these remaining recovery populations will be designated and specific 
boundaries of all recovery populations (large, medium, and small) will 
be delineated by State and local governments, and other interested 
parties, working in coordination with the Service. In contrast to the 
Draft Plan, this revised designation of critical habitat required 
delineation of specific boundaries for all critical habitat areas in 
order to meet the requirements of the Act and our implementing 
regulations. As a result, any future recovery plan developed for the 
PMJM may designate recovery populations or delineate their boundaries 
in a manner inconsistent with the critical habitat units we are 
designating. This may occur if future information changes our 
understanding of the occurrence and distribution of PMJM populations.
    In some HUCs identified in the Draft Plan, little is known 
regarding the status of the PMJM. For example, PMJM has not been 
confirmed to occur in the Crow Creek, Lone Tree, and Bijou HUCs within 
the South Platte River drainage

[[Page 78449]]

in Colorado or in the Big Sandy HUC in the Arkansas River drainage. If 
the PMJM is not present, designation of recovery populations in these 
HUCs may not be necessary, and these HUCs may be deleted from any 
future recovery plan. We do not believe that these areas contain 
features that are essential to the conservation of the species, so we 
are not designating critical habitat within these four HUCs.
    The conservation strategy employed in the Draft Plan emphasizes the 
importance of protecting additional PMJM populations beyond those 
designated as recovery populations, to provide insurance for the PMJM 
in the event that designated recovery populations cannot be effectively 
managed or protected as envisioned or in the event that populations are 
decimated by rare but uncontrollable events, such as catastrophic fires 
or flooding. The Plan recommends directing recovery efforts toward 
public lands, rather than private lands, where possible, and calls upon 
all Federal agencies to protect and manage for the PMJM wherever it 
occurs on Federal lands. However, Federal lands alone cannot fully 
provide for the conservation of the species. Therefore, we included 
non-Federal lands when we found those lands contained the PCEs in the 
appropriate quantity and spatial arrangement to provide the physical 
and biological features essential to the conservation of the species.
    We believe that the designation of areas of critical habitat 
outside of those areas identified for recovery populations, on both 
non-Federal and additional Federal lands, is essential for the 
conservation of the PMJM. Should unforeseen events cause the continued 
decline of PMJM populations throughout the SPR in Colorado, PMJM 
populations and the PCEs on which they depend are more likely to 
persist and remain viable on Federal lands, where consistent and 
effective land management strategies can be more easily employed. These 
additional PMJM populations on Federal lands could serve as substitute 
recovery populations should designated recovery populations decline or 
fail to meet recovery goals. In addition, some PMJM populations on 
Federal lands have been the subject of ongoing research that could 
prove vital to the conservation of the PMJM. Therefore, in addition to 
designating critical habitat for sites consistent with those listed in 
the Draft Plan, we reviewed other sites of PMJM occurrence, especially 
Federal lands, and are designating certain additional units as critical 
habitat that include the requisite PCEs and are known to support the 
PMJM.
    Based on this conservation strategy, we are designating critical 
habitat preferentially on certain Federal lands that support required 
PCEs in the appropriate spatial arrangement and quantity and are 
occupied by the PMJM, where Federal property extends along stream 
reaches at least 3 mi (5 km). This length corresponds to the minimum 
size of small recovery populations as defined by the Draft Plan. These 
areas of critical habitat may include intervening non-Federal lands, 
that in some cases support all PCEs needed by the PMJM or, if 
fragmented by human development, contain at least one of the PCEs and 
are at least likely to provide connectivity between areas of PMJM 
habitat on adjacent Federal lands.
Delineation of Critical Habitat Boundaries
    We are designating revised critical habitat for the PMJM based on 
the interpretation of multiple sources used during our June 23, 2003, 
designation of critical habitat (68 FR 37275); new information 
developed in the preparation of our October 8, 2009, proposed rule (74 
FR 52066); and information we received in response to our request for 
public comments on our October 8, 2009, proposed rule (74 FR 52066) and 
our May 27, 2010, publication (75 FR 29700). For this rule, we used 
GIS-based mapping using ESRI ArcGIS software incorporating USGS 
National Hydrography Dataset streams along with stream order (by 
Strahler code), Colorado Department of Transportation roads, U.S. 
Census Bureau cities, USGS topographic maps, 2005 Farm Service Agency, 
National Agricultural Inventory Program 1m color imagery, and the COMaP 
dataset (Theobald et al. 2008). We divided lands we are designating as 
critical habitat into specific mapping units, i.e., critical habitat 
units, often corresponding to individual HUCs. For the purposes of this 
rule, these units are described primarily by latitude and longitude, 
and by Public Land Survey, Township, Section, and Range, to mark the 
upstream and the downstream extent of critical habitat along rivers and 
streams.
    As in 2003, we were faced with making a decision concerning the 
outward extent of critical habitat into uplands. Studies suggest that 
the PMJM uses uplands at least as far out as 328 ft (100 m) beyond the 
100-year floodplain (Shenk and Sivert 1999a, p. 11; Ryon 1999, p. 12; 
Schorr 2001, p. 14; Shenk 2004; Service 2003a, p. 26). Apparent 
hibernacula (wintering chambers) have been documented outward to 335 ft 
(102 m) of a perennial stream bed or intermittent tributary (Ruggles et 
al. 2003, p. 19). We have typically described potential PMJM habitat as 
extending outward 300 ft (90 m) from the 100-year floodplain of rivers 
and streams (Service 2004a, p. 5). The Draft Plan (Service 2003a, p. 
26) defines PMJM habitat as the 100-year floodplain plus 328 ft (100 m) 
outward on both sides, but allows for alternative delineations that 
provide for all the needs of the PMJM and include the alluvial 
floodplain, transition slopes, and appropriate upland habitat.
    To allow normal behavior and to ensure that the PMJM and the PCEs 
on which it depends are protected, we believe that the outward extent 
of critical habitat should at least approximate the outward distances 
described above in relation to the 100-year floodplain. Unfortunately, 
floodplains have not been mapped for many streams within the PMJM's 
range. Where floodplain mapping is available, we have found that it may 
include local inaccuracies. While alternative delineation of critical 
habitat based on geomorphology and existing vegetation could accurately 
portray the presence and extent of required habitat components, we lack 
an explicit data layer that could support such a delineation of 
critical habitat.
    In 2003, we also considered determining the outward extent of 
critical habitat based on a distance outward from features such as the 
stream edge, associated wetlands, or riparian areas. We judged wetlands 
an inconsistent indicator of habitat extent and found no consistent 
source of riparian mapping available across the SPR of Colorado where 
the PMJM is listed. We also considered using an outward extent of 
critical habitat established by a vertical distance above the elevation 
of the river or stream to approximate the floodplain and adjacent 
uplands likely to be used by the PMJM. This proved unacceptable over 
the diverse topography that surrounds stream reaches occupied by the 
PMJM.
    For this revised designation, we generally maintain consistency 
with our 2003 designation of critical habitat in delineating the upland 
extent of critical habitat boundaries as a set distance outward from 
the river or stream edge (as defined by the ordinary high water mark) 
varying with the size (order) of a river or stream. We compared known 
floodplain widths to stream order over a series of sites and 
approximated average floodplain width for various orders of streams. To 
that average we added 328 ft (100 m) outward on each

[[Page 78450]]

side. For example, this analysis determined the average floodplain for 
streams of order 1 and 2 (the smallest streams) is approximately 33 ft 
(10 m). Based on this calculation, for streams of order 1 and 2, we are 
designating critical habitat as 361 ft (110 m) outward from the stream 
edge; for streams of order 3 and 4, we are designating critical habitat 
as 394 ft (120 m) outward from the stream edge; and for stream orders 5 
and above (the largest streams and rivers), we are designating critical 
habitat as 459 ft (140 m) outward from the stream edge. In each case we 
are approximating average floodplain width plus 328 ft (100 m). While 
critical habitat will not extend outward to all areas used by 
individual mice over time, we believe that these corridors of critical 
habitat ranging from 722 ft (220 m) to 918 ft (280 m) in width (plus 
the river or stream width) will support the full range of PCEs 
essential for conservation of PMJM populations in these reaches, and 
should help protect the PMJM and its habitat from secondary impacts of 
nearby disturbance.
    Following both our July 17, 2002, proposal of critical habitat (67 
FR 47154), and our October 8, 2009, proposal to revise critical habitat 
(74 FR 52066), we received comments regarding the appropriate outward 
limits of critical habitat and means of establishing them. Most 
comments suggested one of two alternative methods: (1) Site-specific 
mapping of critical habitat for each reach; or (2) one outward limit 
for all rivers and streams. We determined that the first alternative 
was not feasible with the resources available to us, and that the 
second alternative less accurately reflected limits of habitat than the 
methodology employed above.
    An exception is our delineation of the outward boundary of 
designated critical habitat in those portions of Units 8, 9, and 10, 
where a Riparian Conservation Zone has been mapped in conjunction with 
development of the Douglas County HCP and delineates the limits of PMJM 
habitat. The RCZ depicts known or potential PMJM habitat over 283 
stream mi (456 km) and over 18,000 ac (7,000 ha) in Douglas County. 
Mapping of the RCZ relied on geomorphology and existing vegetation to 
assess presence and extent of required habitat components (i.e., those 
physical and biological features essential for the conservation of the 
PMJM). It followed the alternative habitat delineation suggested in the 
Draft Plan (Service 2003a), and provides for the needs of the PMJM by 
including the alluvial floodplain, transition slopes, and appropriate 
upland habitat along stream reaches. When we approved the Douglas 
County HCP, we reviewed the methodology and concluded that the RCZ 
reflected the best information available for establishing the limits of 
PMJM habitat.
    Beyond the conclusion that the RCZ boundary provides a more 
accurate depiction of the appropriate boundary of critical habitat than 
what we proposed, we also considered the potential confusion that 
designation of critical habitat that differs from the established RCZ 
boundary might cause. The RCZ has been widely publicized in Douglas 
County and is used as a guide to help avoid impacts to PMJM and its 
habitat. Establishing critical habitat through standard setbacks from 
streams would have created a confusing pattern of dual lines that 
depict PMJM habitat limits. For these reasons we are designating the 
outward boundary of critical habitat on non-Federal lands in Units 8, 
9, and 10 to correspond to the boundaries set by the RCZ, where the RCZ 
is present. In some instances this increases the width of critical 
habitat designated; in others it decreases the width. Overall, it 
results in a decrease in critical habitat than that which would 
otherwise have been designated, but it more accurately reflects on-site 
habitat conditions. On Federal properties designated as revised 
critical habitat in Douglas County, and on a very few non-Federal 
properties not included in the RCZ, outward boundaries of critical 
habitat units include standard distances from streams based on stream 
order.

Revised Critical Habitat Designation

    We are designating 11 units that total approximately 411 mi (662 
km) of rivers and streams and 34,935 ac (14,138 ha) of lands in 
Colorado, including land under Federal, State, local government, and 
private ownership. No lands designated as critical habitat are under 
tribal ownership. The areas we describe below constitute our best 
assessment at this time of areas that meet the definition of critical 
habitat for the PMJM. The units are those areas that are most likely to 
substantially contribute to conservation of the PMJM, will contribute 
to the long-term survival and recovery of the species, and require 
special management considerations or protection. These units, in many 
cases, correspond to the same geographic area of the units in Colorado 
delineated in the 2003 designation. However, there are multiple 
revisions and unit additions. This designation of revised critical 
habitat replaces the former critical habitat designation for the PMJM 
in 50 CFR 17.95(a).
    Table 1 shows each unit, approximate area, and land ownership. 
Estimates reflect the total river or stream length and area of lands 
within critical habitat unit boundaries. Limited areas within these 
boundaries may not include any of the requisite PCEs. Any such 
developed areas or other areas not supporting any of the requisite PCEs 
are excluded by text of this rule, and the total area we are 
designating may, therefore, be less than what is indicated in Table 1.
BILLING CODE 4310-55-P

[[Page 78451]]

[GRAPHIC] [TIFF OMITTED] TR15DE10.001

BILLING CODE 4310-55-C
    Lands that we are designating as revised critical habitat are 
divided into 11 critical habitat units that contain all of the PCEs 
necessary to meet the essential biological needs of the PMJM throughout 
the SPR in Colorado, where PMJM is listed.

[[Page 78452]]

    We present a brief description of each unit, and reasons why it 
meets the definition of critical habitat for the PMJM, below. The units 
are generally based on geographically distinct river drainages and 
subdrainages (HUCs). These units have been subject to, or are 
threatened by, varying degrees of degradation from human use and 
development. For these reasons, the essential features within each of 
the specific areas we are designating as critical habitat may require 
special management considerations or protection. Management may include 
measures in addition to those that may already be in place to preserve 
such areas to avoid, reduce, or offset human-induced and natural 
impacts, and to restore such areas following unavoidable adverse 
impacts, including fire and flooding.
South Platte River Drainage--North of Denver

Unit 1: North Fork of the Cache la Poudre River, Larimer County

    Unit 1 encompasses approximately 8,365 ac (3,385 ha) on 87 mi (140 
km) of streams within the North Fork of the Cache la Poudre River HUC. 
We are designating critical habitat along the lower portions of the 
North Fork of the Cache la Poudre River and its tributaries, to provide 
for the large recovery population specified in the Draft Plan. The unit 
includes the North Fork of the Cache la Poudre River from the Milton 
Seaman Reservoir upstream to the Halligan Reservoir. Major tributaries 
within the unit include Stonewall Creek, Rabbit Creek (including its 
North Fork, Middle Fork, and South Fork), and Lone Pine Creek. The 
Eagle's Nest Open Space area, proposed as critical habitat within Unit 
1, has been excluded from this critical habitat designation (see the 
Exclusions section below). Much of the unit is covered by the 2006 
Livermore Area HCP (Service 2006b). The HCP covers certain incidental 
take of the PMJM related to ongoing agriculture and compatible 
activities, and conservation and stewardship activities in the 
Livermore area. However, the HCP does not address take resulting from 
most development.
    The unit includes both public and private lands. It includes 
portions of the Arapaho-Roosevelt National Forest, as well as Lone Pine 
State Wildlife Area. In the Cache la Poudre HUC, stream reaches that 
contain requisite PCEs are widespread. The area remains largely rural 
and agricultural with habitat components likely to support relatively 
high densities of the PMJM.
    Pressure for residential development is increasing within the area. 
Management of livestock grazing in the unit is often, but not in all 
cases, compatible with maintenance of quality PMJM habitat. Proposed 
reservoir projects and associated water management may impact portions 
of this unit but may also present conservation opportunities. Based on 
these and other threats, special management considerations and 
protection are needed. This unit is essential to the conservation of 
the PMJM because it contains habitat essential to a population of the 
PMJM that supports the conservation principles of redundancy and 
resiliency throughout the SPR in Colorado where the PMJM is listed.

Unit 2: Cache la Poudre River, Larimer County

    Unit 2 encompasses approximately 4,929 ac (1,995 ha) on 51 mi (82 
km) of streams within the Cache la Poudre River watershed. This unit is 
within the Cache la Poudre HUC and south of Unit 1. It includes the 
Cache la Poudre River from Poudre Park upstream to the 7,600 ft (2,317 
m) elevation below Rustic. Major tributaries within the unit include 
Hewlett Gulch, Young Gulch, Skin Gulch, Poverty Gulch, Elkhorn Creek, 
Pendergrass Creek, and Bennett Creek. The unit is primarily composed of 
Federal lands of the Arapaho-Roosevelt National Forest, including 
portions of the Cache la Poudre Wilderness, but includes limited non-
Federal lands as well. The unit supports the appropriate spatial 
arrangement of the requisite PCEs to ensure the conservation of the 
PMJM. Since this unit is located in the same Cache la Poudre HUC as 
Unit 1, it is unlikely to serve as an initial recovery population. 
However, it encompasses a significant area of habitat likely to support 
a sizeable population of the PMJM. Due to Federal ownership, 
residential or commercial development pressure is minimal; however, the 
area is subject to substantial recreational use (rafting, kayaking, 
fishing) in the Cache la Poudre River corridor. Non-Federal lands 
include existing development that may limit the habitat components 
present. Such reaches may serve the PMJM mostly as connectors between 
areas that contain all of the necessary PCEs. Maintenance of 
connectivity for PMJM movement through such areas is important. Based 
on these and other threats, special management considerations and 
protection are needed. This unit is essential to the conservation of 
the PMJM because it contains habitat essential to a population of the 
subspecies that supports the conservation principles of redundancy and 
resiliency throughout the SPR in Colorado where the PMJM is listed.

Unit 3: Buckhorn Creek, Larimer County

    Unit 3 encompasses approximately 3,912 ac (1,583 ha) on 45 mi (73 
km) of streams within the Buckhorn Creek watershed. It includes 
Buckhorn Creek from just west of Masonville, upstream to the 7,600-ft 
(2,317-m) elevation. Major tributaries within the unit include Little 
Bear Gulch, Bear Gulch, Stringtown Gulch, Fish Creek, and Stove Prairie 
Creek. The unit is located in the Big Thompson HUC, and we are 
designating it as critical habitat to address the medium recovery 
population called for this area in the Draft Plan (Service 2003a). The 
unit includes both public lands, mostly on portions of the Arapaho-
Roosevelt National Forest, and private lands. Requisite PCEs are 
present. Pressure for expanded rural development exists on non-Federal 
lands within the unit while recreational use is centered on public 
lands. Based on these and other development pressures, special 
management considerations and protection are needed. This unit is 
essential to the conservation of the PMJM because it contains habitat 
essential to a population of the subspecies that supports the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed.

Unit 4: Cedar Creek, Larimer County

    Unit 4 encompasses approximately 641 ac (259 ha) on 8 mi (12 km) of 
streams within the Cedar Creek watershed, including Dry Creek and Jug 
Gulch. Cedar Creek is a tributary of the Big Thompson River and enters 
the Big Thompson River at Cedar Cove. The unit is centered on Federal 
lands of the Arapaho-Roosevelt National Forest, but includes some 
stream reaches on non-Federal lands. This unit is located in the Big 
Thompson HUC and, while unlikely to serve as an initial recovery 
population, it supports a population on mostly Federal lands of the 
upper Big Thompson River. Requisite PCEs are present, but the unit is 
isolated, at least in terms of riparian connection, from the PMJM 
population on nearby Buckhorn Creek drainage (Unit 3) to the north. 
This site is upstream of The Narrows of the Big Thompson Canyon, a 
barrier to PMJM movement, while the confluence of the Big Thompson 
River and Buckhorn Creek is downstream from The Narrows. However, the 
close proximity of the headwaters of Jug Gulch within this unit to the 
headwaters

[[Page 78453]]

of Bear Gulch within the Buckhorn Creek critical habitat unit suggests 
that some PMJM may pass between the two populations and thus between 
the two significant watersheds within this HUC. Non-Federal lands 
within this unit support existing development and will likely 
experience continued residential development pressure. Therefore, 
special management considerations and protection are needed. This unit 
is essential to the conservation of the PMJM because it contains 
habitat essential to a population of the subspecies that supports the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed.

Unit 5: South Boulder Creek, Boulder County

    Unit 5 encompasses approximately 798 ac (323 ha) on 8 mi (12 km) of 
streams within the South Boulder Creek watershed. It includes South 
Boulder Creek from Baseline Road upstream to Eldorado Springs, and 
includes the Spring Brook tributary. Denver Water lands proposed as 
critical habitat within Unit 5 have been excluded from this critical 
habitat designation (see the Exclusions section). The unit includes 
both public and private lands. It includes substantial lands owned by 
the City of Boulder Open Space and Mountain Parks.
    This unit is located in the St. Vrain HUC, and we are designating 
it as critical habitat to address the medium recovery population 
designated for this area in the Draft Plan (Service 2003a). Requisite 
PCEs are present, and portions of the area have been the subject of 
PMJM research funded by the City of Boulder. At some sites high 
densities of the PMJM have been documented (Meaney et al. 2003, pp. 
616-617). A wide floodplain, complex ditch system, and the irrigation 
of pastures make habitat within the lower portions of this unit unique. 
Pressure for expanded development is occurring on the limited private, 
undeveloped land within the unit. Recreational use of the City of 
Boulder lands is considerable and could adversely impact the PMJM if 
not properly managed. Based on these and other threats, special 
management considerations and protection are needed. This unit is 
essential to the conservation of the PMJM because it contains habitat 
essential to a population of the subspecies that supports the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed.

Unit 6: Rocky Flats Site, Jefferson, Boulder, and Broomfield Counties

    Unit 6 encompasses approximately 1,108 ac (448 ha) on 12 mi (20 km) 
of streams, and includes the Rock Creek Subunit, Woman Creek Subunit, 
and Walnut Creek Subunit. Greater than 99 percent of Unit 6 is within 
the Rocky Flats Site and consists of Federal lands managed by the 
Service and DOE. The Rocky Flats Site was a nuclear industrial facility 
for the DOE between 1951 and the end of the Cold War. Later it became 
the DOE Environmental Technology Site. Much of the Rocky Flats Site 
became the Rocky Flats NWR in 2005, but DOE maintains control over the 
Central Operable Unit (1,300 ac, 530 ha) and other lands near the 
western boundary of the site.
    The Rock Creek Subunit is located in the St. Vrain HUC, and the 
Woman Creek and Walnut Creek subunits are in the Middle South Platte-
Cherry Creek HUC. Since the unit includes portions of two HUCs, both of 
which support designated critical habitat corresponding with recovery 
populations designated elsewhere in the Draft Plan, this unit is 
unlikely to serve as an initial recovery population. However, this unit 
is unique and important because it is limited almost entirely to 
Federal lands of the Rocky Flats Site, and populations on the site have 
been the subject of the longest span of research of any PMJM 
populations.
    This unit is essential to the conservation of the PMJM because 
requisite PCEs are present and the site supports small streams largely 
unimpacted by human development. This unit is essential to the 
conservation of the PMJM because it contains habitat essential to a 
population of the subspecies that supports the conservation principles 
of redundancy and resiliency throughout the SPR in Colorado where the 
PMJM is listed. In addition, the site presents an opportunity to study 
small populations and their viability over time. However, the small 
populations present and their apparent isolation suggest that the PMJM 
population on the unit may be vulnerable. Continuation of existing 
management and adapting future management to support conservation of 
the PMJM on site is necessary on both NWR and DOE lands.

Unit 7: Ralston Creek, Jefferson County

    Unit 7 encompasses approximately 773 ac (313 ha) on 9 mi (14 km) of 
streams within the Ralston Creek watershed. It includes Ralston Creek 
from Ralston Reservoir upstream to the 7,600-ft (2,317-m) elevation. 
Denver Water lands proposed as critical habitat within Unit 7 have been 
excluded from this critical habitat designation (see the Exclusions 
section). The unit includes both public and private lands including 
lands in Golden Gate Canyon State Park and White Ranch County Park.
    This unit is located in the Clear Creek HUC, and we are designating 
it as critical habitat to partially address the criteria of three small 
recovery populations or one medium recovery population called for in 
this area in the Draft Plan (Service 2003a). The segment of Ralston 
Creek that passes through the Cotter Corporation's existing 
Schwartzwalder Mine serves as a connector between areas that support 
all requisite PCEs required by the PMJM located upstream and 
downstream. Protection and management considerations are required for 
both the mine area and public lands within the unit. This unit is 
essential to the conservation of the PMJM because it contains habitat 
essential to a population of the subspecies that supports the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed.
South Platte River Drainage--South of Denver

Unit 8: Cherry Creek, Douglas County

    Unit 8 encompasses approximately 2,536 ac (1,026 ha) on 30 mi (48 
km) of streams within the Cherry Creek watershed. Unit 8 includes two 
subunits. The first, the Lake Gulch Subunit, includes Cherry Creek from 
the downstream boundary of the Castlewood Canyon State Recreation Area, 
upstream to its confluence with Lake Gulch. Tributaries within the 
subunit include Lake Gulch and Upper Lake Gulch. It includes portions 
of the Castlewood Canyon State Recreation Area, as well as portions of 
Douglas County's Green Mountain Ranch property. The second, the 
Antelope Creek Subunit, includes Antelope Creek from its confluence 
with West Cherry Creek upstream and a tributary, Haskel Creek. The 
outward boundaries of critical habitat in this subunit have been 
modified from those proposed to conform to boundaries of the Douglas 
County RCZ on non-Federal lands where the RCZ has been mapped (see the 
Delineation of Critical Habitat Boundaries section above). The two 
subunits include both public and private lands. These subunits are 
located in the Middle South Platte-Cherry Creek HUC and address the 
medium recovery population designated

[[Page 78454]]

for this area in the Draft Plan (Service 2003a). PCEs essential to the 
conservation of the PMJM in the upper reaches of the Cherry Creek basin 
appear widespread, and there are multiple options as to where we could 
designate critical habitat for a medium recovery population. This unit 
is also essential to the conservation of the PMJM because it provides 
critical habitat to support populations of the subspecies to meet the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed. Some development pressure is 
occurring from expanding rural development on private lands within 
these areas. Management considerations are required for development 
within this unit, as well as for grazing and recreational activities.

Unit 9: West Plum Creek, Douglas County

    Unit 9 encompasses approximately 5,518 ac (2,233 ha) on 90 mi (145 
km) of streams within the Plum Creek watershed. It includes Plum Creek 
from Chatfield Reservoir upstream to the confluence with West Plum 
Creek then continues upstream on West Plum Creek to its headwaters. 
Major tributaries within the unit include Indian Creek, Jarre Creek, 
Garber Creek (including North, Middle, and South Garber Creek), Jackson 
Creek, Spring Creek, Dry Gulch, Bear Creek, Starr Canyon, Gove Creek, 
and Metz Canyon. We have reduced the extent of final critical habitat 
on Bear Creek from that proposed, ending it at the base of the Waconda 
Lake Dam (see the Summary of Changes from the Proposed Rule section 
above). Denver Water lands proposed as critical habitat within Unit 9 
have been excluded from this critical habitat designation (see the 
Exclusions section below). The outward boundaries of critical habitat 
in this unit have been modified from those proposed to conform to 
boundaries of the Douglas County RCZ on non-Federal lands where the RCZ 
has been mapped (see the Delineation of Critical Habitat Boundaries 
section above).
    The unit encompasses both public and private lands. It includes 
portions of the Pike-San Isabel National Forest, as well as Chatfield 
State Recreation Area (Corps property), and Colorado Division of 
Wildlife's Woodhouse Ranch property. This unit is located in the Upper 
South Platte HUC, and it addresses the large recovery population 
designated for this area in the Draft Plan (Service 2003a). Aside from 
a portion of lower Plum Creek, the unit remains rather rural, requisite 
PCEs are present, and it includes habitat components likely to support 
relatively high densities of the PMJM. Pressure for expanded suburban 
and rural development is occurring within the area. On some private and 
public lands, management considerations are required for livestock 
grazing. This unit is essential to the conservation of the PMJM because 
it contains habitat essential to a population of the subspecies that 
supports the conservation principles of redundancy and resiliency 
throughout the SPR in Colorado where the PMJM is listed.

Unit 10: Upper South Platte River, Douglas, Jefferson, and Teller 
Counties

    Unit 10 encompasses approximately 3,060 ac (1,238 ha) on 34 mi (54 
km) of streams within the South Platte River watershed. It includes 
four subunits. The Chatfield Subunit includes a section of the South 
Platte River upstream of Chatfield Reservoir within Chatfield State 
Recreation Area (Corps property). The Bear Creek Subunit includes Bear 
Creek and West Bear Creek, tributaries to the South Platte River. The 
South Platte Subunit includes a segment of the South Platte River 
upstream from Nighthawk, including the tributaries Gunbarrel Creek and 
Sugar Creek. This subunit is centered on Federal lands of the Pike-San 
Isabel National Forest but includes some intervening non-Federal lands. 
The Trout Creek Subunit includes portions of Trout Creek, a tributary 
to Horse Creek, and also portions of Eagle Creek, Long Hollow, Fern 
Creek, Illinois Gulch, and Missouri Gulch. This subunit is centered on 
Federal lands of the Pike-San Isabel National Forest but includes some 
intervening non-Federal lands along Trout Creek. Denver Water lands 
proposed as critical habitat within Unit 10 have been excluded from 
this critical habitat designation (see the Exclusions section below). 
The outward boundaries of critical habitat in this unit have been 
modified from those proposed to conform to boundaries of the Douglas 
County RCZ on non-Federal lands in Douglas County where the RCZ has 
been mapped (see the Delineation of Critical Habitat Boundaries section 
above).
    This unit is located in the same Upper South Platte HUC as West 
Plum Creek, where the Draft Plan designated a large recovery population 
and, therefore, is unlikely to serve as an initial recovery population. 
The unit encompasses four areas of primarily Federal land spread 
through the drainage, three within the Pike-San Isabel National Forest 
boundary. While requisite PCEs are present, habitat components present 
and the likely density of PMJM populations vary. The Trout Creek 
Subunit appears to have high quality PMJM habitat and may provide a 
continued opportunity to research relationships between the PMJM and 
the western jumping mouse (Z. princeps), both of which have been 
verified from the same trapping effort on Trout Creek. The four subunit 
areas should ensure that populations of the PMJM sufficient for its 
conservation are maintained in the portion of this HUC upstream of 
Chatfield Reservoir on the South Platte River and its tributaries. This 
unit is essential to the conservation of the PMJM because it contains 
habitat essential to populations of the subspecies that supports the 
conservation principles of redundancy and resiliency throughout the SPR 
in Colorado where the PMJM is listed. Due to Federal ownership, 
residential or commercial development pressure is minimal; however, the 
area is subject to substantial recreational use. Proposed reservoir 
projects may impact portions of this unit. Based on these and other 
development pressures, special management considerations and protection 
are needed.
Arkansas River Drainage

Unit 11: Monument Creek, El Paso County

    Unit 11 is located in the Arkansas River drainage. It encompasses 
approximately 3,295 ac (1,333 ha) on 38 mi (61 km) of streams within 
the Monument Creek watershed. It includes Monument Creek from the 
confluence of Cottonwood Creek upstream to the southern boundary of the 
U.S. Air Force (USAF) Academy (Academy) and from the northern boundary 
of the Academy upstream to the dam at Monument Lake. Major tributaries 
within the unit include Kettle Creek, Black Squirrel Creek, Monument 
Branch, Middle Tributary, Smith Creek, Jackson Creek, Beaver Creek, 
Teachout Creek, and Dirty Woman Creek. The unit is primarily on private 
lands. It includes a small portion of the Pike-San Isabel National 
Forest. Lands within the Struthers Ranch, Dahle Property, and Lefever 
Property HCPs, which were proposed as critical habitat within this 
unit, have been excluded from this critical habitat designation (see 
Exclusions, below).
    This unit is located in the Fountain Creek HUC, and we are 
designating it as critical habitat to address part of the large 
recovery population designated for this area in the Draft Plan (Service 
2003a). The area is unique in that it represents the only known PMJM 
population of significant size within the Arkansas River drainage and 
the southernmost known occurrence of the PMJM. The Draft Plan (Service 
2003a)

[[Page 78455]]

specifies a large recovery population along Monument Creek and its 
tributaries including lands within the Academy. While the Academy lands 
support the requisite PCEs, support a significant PMJM population, and 
are essential to maintenance of this proposed recovery population, we 
determined that the Academy lands merit exemption under section 4(a)(3) 
of the Act because an integrated natural resources management plan is 
in place that addresses conservation of the PMJM.
    Requisite PCEs are present throughout this unit, but development 
pressure is extremely high on some private lands within the unit. 
Development has resulted in changes in base flows and increased 
stormwater runoff, and has adversely impacted stream channels and 
associated riparian systems (Mihlbachler 2007). Comprehensive 
management measures to address habitat degradation are needed.

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that actions they fund, authorize, or carry out are 
not likely to destroy or adversely modify critical habitat. Decisions 
by the Fifth and Ninth Circuits Court of Appeals have invalidated our 
definition of destruction or adverse modification (50 CFR 402.02) (see 
Gifford Pinchot Task Force v. U.S. Fish and Wildlife Service, 378 F.3d 
1059 (9th Cir. 2004) and Sierra Club v. U.S. Fish and Wildlife Service 
et al., 245 F.3d 434, 442 (5th Cir. 2001)), and we do not rely on this 
regulatory definition when we analyze whether an action is likely to 
destroy or adversely modify critical habitat. Under the statutory 
provisions of the Act, we determine destruction or adverse modification 
on the basis of whether, with implementation of the proposed Federal 
action, the affected critical habitat would remain functional (or 
retain those physical and biological features that relate to the 
ability of the area to periodically support the subspecies) to serve 
its intended conservation role for the subspecies.
    If a species is listed or critical habitat is designated, section 
7(a)(2) of the Act requires Federal agencies to ensure that activities 
they authorize, fund, or carry out are not likely to jeopardize the 
continued existence of the species or to destroy or adversely modify 
its critical habitat. If a Federal action may affect a listed species 
or its critical habitat, the responsible Federal agency (action agency) 
must enter into consultation with us. As a result of this consultation, 
we document compliance with the requirements of section 7(a)(2) through 
our issuance of:
    (1) A concurrence letter for Federal actions that may affect, but 
are not likely to adversely affect, listed species or critical habitat; 
or
    (2) A biological opinion for Federal actions that may affect, and 
are likely to adversely affect, listed species or critical habitat.
    An exception to the concurrence process referred to in (1) above 
occurs in consultations that involve National Fire Plan projects, known 
as Section 7 Counterpart Regulations for National Fire Plan Projects. 
In 2004, the USFS and the Bureau of Land Management (BLM) reached 
agreements with us to streamline a portion of the section 7 
consultation process (BLM 2004, pp. 1-8; USFS 2004, pp. 1-8). Under 
these regulations Alternative Consultation Agreements allow the USFS 
and the BLM the opportunity to make ``not likely to adversely affect'' 
determinations for projects that implement the National Fire Plan, and 
do not need to submit these projects for concurrence. Such projects 
include prescribed fire, mechanical fuels treatments (thinning and 
removal of fuels to prescribed objectives), emergency stabilization, 
burned area rehabilitation, road maintenance and operation activities, 
ecosystem restoration, and culvert replacement actions. The USFS and 
the BLM must ensure staffs are properly trained, and both agencies must 
submit monitoring reports to us to determine if the procedures are 
being implemented properly and that effects on endangered species and 
their habitats are being properly evaluated.
    When we issue a biological opinion concluding that a project is 
likely to jeopardize the continued existence of a listed species or 
destroy or adversely modify critical habitat, we also provide 
reasonable and prudent alternatives to the project, if any are 
identifiable. We define reasonable and prudent alternatives at 50 CFR 
402.02 as alternative actions identified during consultation that:
    (1) Can be implemented in a manner consistent with the intended 
purpose of the action;
    (2) Can be implemented consistent with the scope of the Federal 
agency's legal authority and jurisdiction;
    (3) Are economically and technologically feasible; and
    (4) Would, in the Director's opinion, avoid jeopardizing the 
continued existence of the listed species or destroying or adversely 
modifying critical habitat.
    Reasonable and prudent alternatives can vary from slight project 
modifications to extensive redesign or relocation of the project. Costs 
associated with implementing a reasonable and prudent alternative are 
similarly variable.
    Regulations at 50 CFR 402.16 require Federal agencies to reinitiate 
consultation on previously reviewed actions in instances where we have 
listed a new species or subsequently designated critical habitat that 
may be affected and the Federal agency has retained discretionary 
involvement or control over the action (or the agency's discretionary 
involvement or control is authorized by law). Consequently, Federal 
agencies may sometimes need to request reinitiation of consultation 
with us on actions for which formal consultation has been completed, if 
those actions with discretionary involvement or control may affect 
subsequently listed species or designated critical habitat.
    Federal activities that may affect the PMJM or its designated 
critical habitat require section 7 consultation under the Act. 
Activities on State, Tribal, local, or private lands requiring a 
Federal permit (such as a permit from the Corps under section 404 of 
the Clean Water Act (33 U.S.C. 1251 et seq.) or a permit from us under 
section 10 of the Act) or involving some other Federal action (such as 
funding from the Federal Highway Administration, Federal Aviation 
Administration, or the Federal Emergency Management Agency) are subject 
to the section 7 consultation process. Federal actions not affecting 
listed species or critical habitat, and actions on State, tribal, 
local, or private lands that are not federally funded, authorized, or 
permitted, do not require section 7 consultations.
    The designation of critical habitat does not imply that lands 
outside of critical habitat do not play an important role in the 
conservation of the PMJM. Federal actions that may affect areas outside 
of critical habitat, such as development, agricultural activities, and 
road construction, are still subject to review under section 7 of the 
Act if they may affect the PMJM, because Federal agencies must consider 
both effects to the species and effects to critical habitat 
independently. The prohibitions of section 9 of the Act applicable to 
the PMJM under 50 CFR 17.31 also continue to apply both inside and 
outside of designated critical habitat.

[[Page 78456]]

Application of the Jeopardy and Adverse Modification Standards

Jeopardy Standard
    Currently, the Service applies an analytical framework for PMJM 
jeopardy analyses that relies heavily on the importance of known 
populations to the species' survival and recovery. The analysis 
required by section 7(a)(2) of the Act is focused not only on these 
populations but also on the habitat conditions necessary to support 
them.
    The jeopardy analysis usually expresses the survival and recovery 
needs of the PMJM in a qualitative fashion without making distinctions 
between what is necessary for survival and what is necessary for 
recovery. Generally, the jeopardy analysis focuses on the rangewide 
status of the SPR where the PMJM is threatened, the factors responsible 
for that condition, and what is necessary for this species to survive 
and recover. An emphasis is also placed on characterizing the condition 
of the PMJM in the area affected by the proposed Federal action and the 
role of affected populations in the survival and recovery of the PMJM. 
That context is then used to determine the significance of adverse and 
beneficial effects of the proposed Federal action and any cumulative 
effects for purposes of making the jeopardy determination.
Adverse Modification Standard
    The key factor related to the adverse modification determination is 
whether, with implementation of the proposed Federal action, the 
affected critical habitat would continue to serve its intended 
conservation role for the species, or retain those PCEs that relate to 
the ability of the area to periodically support the species. Activities 
that may destroy or adversely modify critical habitat are those that 
alter the PCEs to an extent that appreciably reduces the conservation 
value of critical habitat for the PMJM. As discussed above, the role of 
critical habitat is to support the life-history needs of the species 
and provide for the conservation of the species.
    Section 4(b)(8) of the Act requires us to briefly evaluate and 
describe, in any proposed or final regulation that designates critical 
habitat, activities involving a Federal action that may destroy or 
adversely modify such habitat, or that may be affected by such 
designation.
    Activities that, when carried out, funded, or authorized by a 
Federal agency, may adversely affect critical habitat and, therefore, 
should result in consultation for the PMJM include, but are not limited 
to, the following:
    (1) Any activity that results in development or alteration of the 
landscape within a unit, including: land clearing; activities 
associated with construction for urban and industrial development, 
roads, bridges, pipelines, or bank stabilization; agricultural 
activities such as plowing, disking, haying, or intensive grazing; off-
road vehicle activity; and mining or drilling of wells.
    (2) Any activity that results in changes in the hydrology of the 
unit, including: construction, operation, and maintenance of levees, 
dams, berms, and channels; activities associated with flow control, 
such as releases, diversions, and related operations; irrigation; 
sediment, sand, or gravel removal; and other activities resulting in 
the draining or inundation of a unit.
    (3) Any sale, exchange, or lease of Federal land that is likely to 
result in the habitat in a unit being destroyed or appreciably 
degraded.
    (4) Any activity that detrimentally alters natural processes in a 
unit, including changes to inputs of water, sediment and nutrients, or 
any activity that significantly and detrimentally alters water quantity 
in the unit.
    (5) Any activity that could lead to the introduction, expansion, or 
increased density of an exotic plant or animal species that is 
detrimental to the PMJM and to its habitat.
    Note that the scale of these activities would be a crucial factor 
in determining whether, in any instance, they would directly or 
indirectly alter critical habitat to the extent that the value of the 
critical habitat for the survival and recovery of the PMJM would be 
appreciably diminished.
    We consider all of the units we are designating as critical habitat 
to contain features essential to the conservation of the PMJM and which 
require special management. All of the units are within the geographic 
range of the species and the SPR in Colorado where it is listed, and 
they are believed to be currently occupied. To ensure that their 
actions do not jeopardize the continued existence of the PMJM, Federal 
agencies already consult with us on activities in areas currently 
occupied by the PMJM, or in unoccupied areas if the species may be 
affected by the action. Federal actions not affecting listed species or 
critical habitat and actions on non-Federal lands that are not 
federally funded or permitted do not require section 7 consultation.

Exemptions--Application of Section 4(a)(3) of the Act

    The Sikes Act Improvement Act of 1997 (Sikes Act) (16 U.S.C. 670a) 
required each military installation that includes land and water 
suitable for the conservation and management of natural resources to 
complete an integrated natural resources management plan (INRMP) by 
November 17, 2001. An INRMP integrates implementation of the military 
mission of the installation with stewardship of the natural resources 
found on the base. Each INRMP includes:
     An assessment of the ecological needs on the installation, 
including the need to provide for the conservation of listed species;
     A statement of goals and priorities;
     A detailed description of management actions to be 
implemented to provide for these ecological needs; and
     A monitoring and adaptive management plan.
    Among other things, each INRMP must, to the extent appropriate and 
applicable, provide for fish and wildlife management; fish and wildlife 
habitat enhancement or modification; wetland protection, enhancement, 
and restoration where necessary to support fish and wildlife; and 
enforcement of applicable natural resource laws.
    The National Defense Authorization Act for Fiscal Year 2004 (Pub. 
L. 108-136) amended the Act to limit areas eligible for designation as 
critical habitat. Specifically, section 4(a)(3)(B)(i) of the Act (16 
U.S.C. 1533(a)(3)(B)(i)) now provides: ``The Secretary shall not 
designate as critical habitat any lands or other geographical areas 
owned or controlled by the Department of Defense, or designated for its 
use, that are subject to an integrated natural resources management 
plan prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if 
the Secretary determines in writing that such plan provides a benefit 
to the species for which critical habitat is proposed for 
designation.''
    We consult with the military on the development and implementation 
of INRMPs for installations with federally listed species. We analyzed 
INRMPs developed by military installations that are located within the 
SPR in Colorado where the PMJM is listed and that contain those 
features essential to the species' conservation to determine if they 
are exempt under the authority of section 4(a)(3)(B) of the Act.
U.S. Air Force Academy
    The Academy, in El Paso County, is the lone Department of Defense 
property that supports a population of the PMJM in habitat that we 
determined contains physical and biological features that are essential 
to the conservation of the

[[Page 78457]]

species. The Academy completed an INRMP in 1998, and updated it in 2008 
(USAF 1998, 2008). The Academy's INRMP describes habitats found at the 
Academy, including habitats used by the PMJM (USAF 1998, 2008). It 
addresses management concerns, provides goals and objectives regarding 
the PMJM, and describes management actions designed to accomplish those 
objectives. The INRMP also requires monitoring, evaluation of the 
plan's effectiveness, and modification of management actions when 
appropriate.
    The Academy also developed a Conservation Agreement with the 
Service and an accompanying ``Conservation and Management Plan for the 
Preble's Meadow Jumping Mouse at the U.S. Air Force Academy'' in 1999 
(USAF 1999). The Conservation agreement was extended for 5 years in 
2009. The plan provides guidance for USAF management decisions. In 
addition, the Service completed a programmatic section 7 consultation 
in 2000, addressing certain activities at the Academy that may affect 
the PMJM (Service 2000), and concurred with 2008 changes to the INRMP.
    We have reviewed these measures and have concluded the INRMP 
addresses the four criteria identified above. As a result, we did not 
propose Academy lands as critical habitat and have not included Academy 
lands in this final designation. Based on the above considerations, and 
in accordance with section 4(a)(3)(B)(i) of the Act, we have determined 
that the Academy lands are subject to the Academy's INRMP, and that 
conservation efforts identified in the INRMP will provide a benefit to 
PMJM occurring in habitats within or adjacent to these facilities. 
Therefore, lands within this installation are exempt from critical 
habitat designation under section 4(a)(3) of the Act. As a result, we 
are not including a total of approximately 3,300 ac (1,300 ha) of 
habitat in this Department of Defense installation in this final 
critical habitat designation.

Exclusions--Application of Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act states that the Secretary must designate 
and revise critical habitat on the basis of the best available 
scientific data after taking into consideration the economic impact, 
national security impact, and any other relevant impact of specifying 
any particular area as critical habitat. The Secretary may exclude an 
area from critical habitat if he determines that the benefits of such 
exclusion outweigh the benefits of specifying such area as part of the 
critical habitat, unless he determines, based on the best scientific 
data available, that the failure to designate such area as critical 
habitat will result in the extinction of the species. In making that 
determination, the statute on its face, as well as the legislative 
history, are clear that the Secretary has broad discretion regarding 
which factor(s) to use and how much weight to give to any factor.
    Under section 4(b)(2) of the Act, we may exclude an area from 
designated critical habitat based on economic impacts, impacts on 
national security, or any other relevant impacts. In considering 
whether to exclude a particular area from the designation, we must 
identify the benefits of including the area in the designation, 
identify the benefits of excluding the area from the designation, and 
determine whether the benefits of exclusion outweigh the benefits of 
inclusion. If, based on this analysis, the Secretary makes this 
determination, then he can exercise his discretion to exclude the area 
only if such exclusion would not result in the extinction of the 
species.
    When considering the benefits of inclusion for an area, we consider 
the additional regulatory benefits under section 7 of the Act that area 
would receive from the protection from adverse modification or 
destruction as a result of actions with a Federal nexus, the 
educational benefits of mapping essential habitat for recovery of the 
listed species, and any benefits that may result from a designation due 
to State or Federal laws that may apply to critical habitat.
    When considering the benefits of exclusion, we consider, among 
other things, whether exclusion of a specific area is likely to result 
in conservation; the continuation, strengthening, or encouragement of 
partnerships; or implementation of a management plan that provides 
equal to or more conservation that a critical habitat designation would 
provide.
    In the case of PMJM, the benefits of critical habitat include 
public awareness of PMJM presence and the importance of habitat 
protection, and in cases where a Federal nexus exists, increased 
habitat protection for PMJM due to the protection from adverse 
modification or destruction of critical habitat.
    In evaluating the existence of a conservation plan when considering 
the benefits of exclusion, we consider a variety of factors, including 
but not limited to, whether the plan is finalized; how it provides for 
the conservation of the essential physical and biological features; 
whether there is a reasonable expectation that the conservation 
management strategies and actions contained in a management plan will 
be implemented into the future; whether the conservation strategies in 
the plan are likely to be effective; and whether the plan contains a 
monitoring program or adaptive management to ensure that the 
conservation measures are effective and can be adapted in the future in 
response to new information.
    After evaluating the benefits of inclusion and the benefits of 
exclusion, the two sides are carefully weighed to determine whether the 
benefits of exclusion outweigh those of inclusion. If they do, we then 
determine whether exclusion of the particular area would result in 
extinction of the species. If exclusion of an area from critical 
habitat will result in extinction, that area will not be excluded from 
the designation.
    Based on the information provided by entities seeking exclusion, as 
well as additional public comments we received, we evaluated whether 
certain lands in the proposed critical habitat were appropriate for 
exclusion from this final designation. We considered the areas 
discussed below for exclusion under section 4(b)(2) of the Act, and 
present our detailed analysis below. For those areas in which the 
Secretary has exercised his discretion to exclude, we believe that:
    (1) Their value for conservation will be preserved for the 
foreseeable future by existing protective actions, or
    (2) The benefits of excluding the particular area outweigh the 
benefits of their inclusion, based on the ``other relevant factor'' 
provisions of section 4(b)(2) of the Act.

Exclusions Based on Economic Analysis

    Under section 4(b)(2) of the Act, we consider the economic impacts 
of specifying any particular area as critical habitat. In order to 
consider economic impacts, we prepared a DEA, based on the October 8, 
2009, proposed rule (74 FR 52066), which we made available for public 
review on May 27, 2010 (75 FR 29700). We opened a comment period on the 
DEA for 30 days, until June 28, 2010. Following the close of the 
comment period, an FEA of the potential economic effects of the 
designation was developed, taking into consideration these comments and 
any new information.
    The intent of the FEA is to identify and analyze the potential 
economic impacts associated with the final revised critical habitat 
designation for the PMJM in the SPR in Colorado where it is listed 
under the Act. The FEA quantifies the economic impacts of all potential 
conservation efforts for the PMJM, which are the co-extensive costs. 
The majority of these costs will likely be

[[Page 78458]]

incurred regardless of whether or not we designate revised critical 
habitat. The economic impact of the revised critical habitat 
designation is analyzed by comparing scenarios both ``with critical 
habitat'' and ``without critical habitat.'' The ``without critical 
habitat'' scenario represents the baseline for the analysis, 
considering protections already in place for the species (e.g., under 
the Federal listing and other Federal, State, and local regulations), 
but not including critical habitat designated in 2003. Therefore, the 
baseline represents the costs incurred regardless of whether critical 
habitat is designated. The ``with critical habitat'' scenario describes 
the incremental impacts associated specifically with the proposed 
designation of revised critical habitat for the species. The 
incremental conservation efforts and associated impacts are those not 
expected to occur absent the designation of critical habitat for the 
species. In other words, the incremental costs are those attributable 
solely to the designation of critical habitat above and beyond the 
baseline costs; these are the costs we considered in the final 
designation of revised critical habitat. The analysis looked 
retrospectively at baseline impacts incurred since the species was 
listed, and forecasted both baseline and incremental impacts likely to 
occur with the final revised critical habitat designation.
    The FEA also addresses how potential economic impacts are likely to 
be distributed, including an assessment of any local or regional 
impacts of habitat conservation and the potential effects of 
conservation activities on government agencies, private businesses, and 
individuals. The FEA measures lost economic efficiency associated with 
residential and commercial development, public projects, and 
activities, such as economic impacts on water management and 
transportation projects, Federal lands, small entities, and the energy 
industry. Decision-makers can use this information to assess whether 
the effects of the designation might unduly burden a particular group 
or economic sector. Finally, the FEA looks retrospectively at costs 
that have been incurred since May 13, 1998, when the PMJM was listed 
under the Act (63 FR 26517), and considers those costs that may occur 
in the 20 years following the designation of critical habitat, which 
was determined to be the appropriate period for analysis because 
limited planning information was available for most activities to 
forecast activity levels for projects beyond a 20-year timeframe. The 
FEA quantifies economic impacts from PMJM conservation efforts 
associated with the following categories of activity: residential and 
commercial development; roads/bridges, utilities, and bank 
stabilization projects; water supply development; USFS land management; 
Rocky Flats Site land management; and gravel mining.
    Based on the FEA, co-extensive costs (the economic impacts of all 
potential conservation efforts for the PMJM) are expected to be from 
$89 million to $202 million, assuming a 7 percent discount rate, over 
the next 20 years. Potential incremental impacts associated with the 
revised critical habitat designation are estimated to be $28.2 million 
to $63.4 million (approximately $2.66 million to $5.98 million on an 
annualized basis), assuming a 7 percent discount rate, over the next 20 
years. These incremental impacts generally consist of those incremental 
administrative costs of conducting section 7 consultations with the 
Service, and additional costs of project modifications undertaken to 
avoid adverse modification of critical habitat and avoid or minimize 
adverse impacts to critical habitat. In the high-end scenario, 
potential impacts to residential and commercial development represent 
92 percent of the co-extensive costs and 96 percent of the incremental 
impacts, assuming a 7 percent discount rate. The largest contributor to 
incremental costs is residential and commercial development in Unit 9 
(West Plum Creek), Unit 10 (Upper South Platte), and Unit 11 (Monument 
Creek). The following table provides estimates of co-extensive impacts 
and those attributable to designation of critical habitat, by activity, 
over the next 20 years. Table 2 (below) gives a comparison and summary 
of both the total (co-extensive) costs estimated for all PMJM 
conservation activities, and the incremental costs resulting from the 
revised designation of critical habitat for the PMJM, projected over 20 
years, at a 7 percent discount rate.

    Our economic analysis did not identify any disproportionate costs 
that are likely to result from the designation. Consequently, the 
Secretary has determined not to exert his discretion to exclude any 
areas from this designation of critical habitat for the PMJM based on 
economic impacts. A copy of the FEA with supporting documents may be 
obtained by contacting the Colorado Ecological Services Office (see 
ADDRESSES) or by downloading from the Internet at http://www.regulations.gov.

Exclusions Based on National Security Impacts

    Under section 4(b)(2) of the Act, we consider whether there are 
lands owned or managed by the Department of Defense (DOD) where the 
designation of critical habitat might present an impact to national 
security. In preparing this final rule, we have determined that the 
lands within the revised designation of critical habitat for the PMJM 
are not owned or managed by the DOD, and, therefore, we anticipate no 
impact to national security. The Secretary has determined not to exert 
his discretion to exclude any areas from this final designation based 
on impacts on national security.

[[Page 78459]]

Exclusions Based on Other Relevant Impacts

    Under section 4(b)(2) of the Act, we consider other relevant 
impacts, in addition to economic impacts and impacts on national 
security. We consider a number of factors, including whether landowners 
have developed any HCPs or other resource management plans for the 
areas proposed for designation, or whether there are conservation 
partnerships that would be encouraged by designation of, or exclusion 
from, critical habitat. In addition, we look at any Tribal issues, and 
consider the government-to-government relationship of the United States 
with Tribal entities. We also consider any social impacts that might 
occur because of the designation.
    Our NEPA analysis may also disclose impacts we may consider in our 
analysis under section 4(b)(2) of the Act. In order to consider 
environmental impacts of the designation of critical habitat, we 
prepared a draft environmental assessment, based on the October 8, 
2009, proposed rule (74 FR 52066), and made it available for public 
review on May 27, 2010, (75 FR 29700). We opened a comment period on 
the draft environmental assessment for 30 days, until June 28, 2010. 
Following the close of the comment period, a final environmental 
assessment of the potential environmental effects of the designation 
was developed, taking into consideration comments and any new 
information. A copy of the final environmental assessment and Finding 
of No Significant Impact (FONSI) may be obtained by contacting the 
Colorado Ecological Services Office (see ADDRESSES), or by downloading 
from the Internet at http://www.regulations.gov.
    In order to exclude a particular area from the designation, we must 
identify the benefits of including the area in the designation, 
identify the benefits of excluding the area from the designation, and 
determine whether the benefits of exclusion outweigh the benefits of 
inclusion. If based on this analysis, we determine that the benefits of 
exclusion outweigh the benefits of inclusion, then we can exclude the 
area only if such exclusion would not result in the extinction of the 
species.
Benefits of Designating Critical Habitat

Regulatory Benefits

    The consultation provisions under section 7(a) of the Act 
constitute the regulatory benefits of critical habitat. As discussed 
above, Federal agencies must consult with us on actions that may affect 
critical habitat and must avoid destroying or adversely modifying 
critical habitat. Prior to our designation of critical habitat, Federal 
agencies consult with us on actions that may affect a listed species 
and must refrain from undertaking actions that are likely to jeopardize 
the continued existence of the species. Thus, the analysis of effects 
to critical habitat is a separate and different analysis from that of 
the effects to the species. The difference in outcomes of these two 
analyses represents the regulatory benefit of critical habitat. For 
some species, and in some locations, the outcome of these analyses will 
be similar, because effects on habitat will often result in effects on 
the species. However, the regulatory standard is different: the 
jeopardy analysis looks at the action's impact on survival and recovery 
of the species, while the adverse modification analysis looks at the 
action's effects on the designated habitat's contribution to the 
species' conservation. This will, in many instances, lead to different 
results and different regulatory requirements.
    Once an agency determines that consultation under section 7 of the 
Act is necessary, the process may conclude informally when we concur in 
writing that the proposed Federal action is not likely to adversely 
affect critical habitat. However, if we determine through informal 
consultation that adverse impacts are likely to occur, then we would 
initiate formal consultation, which would conclude when we issue a 
biological opinion on whether the proposed Federal action is likely to 
result in destruction or adverse modification of critical habitat.
    For critical habitat, a biological opinion that concludes in a 
determination of no destruction or adverse modification may contain 
discretionary conservation recommendations to minimize adverse effects 
to PCEs, but it would not contain any mandatory reasonable and prudent 
measures or terms and conditions. We suggest reasonable and prudent 
alternatives to the proposed Federal action only when our biological 
opinion results in an adverse modification conclusion.
    In providing the framework for the consultation process, the 
previous section applies to all the following discussions of benefits 
of inclusion or exclusion of critical habitat.
    The process of designating critical habitat as described in the Act 
requires that the Service identify those lands on which are found the 
physical or biological features essential to the conservation of the 
species which may require special management considerations or 
protection. In identifying those lands, the Service must consider the 
recovery needs of the species, such that the habitat that is 
identified, if managed, could provide for the survival and recovery of 
the species. Furthermore, once critical habitat has been designated, 
Federal agencies must consult with the Service under section 7(a)(2) of 
the Act to ensure that their actions will not adversely modify 
designated critical habitat or jeopardize the continued existence of 
the species. As noted in the Ninth Circuit's Gifford Pinchot decision, 
the Court ruled that the jeopardy and adverse modification standards 
are distinct, and that adverse modification evaluations require 
consideration of impacts to the recovery of species. Thus, through the 
section 7(a)(2) consultation process, critical habitat designations 
provide recovery benefits to species by ensuring that Federal actions 
will not destroy or adversely modify designated critical habitat.
    The identification of lands that are necessary for the conservation 
of the species can assist in the recovery planning for a species, and 
therefore is beneficial. In this case the Draft Plan has helped inform 
critical habitat designation, and this final rule may, in turn, 
contribute to development of a final recovery plan. The process of 
proposing and finalizing a critical habitat rule provides the Service 
with the opportunity to determine lands essential for conservation as 
well as identify the physical and biological features essential for 
conservation on those lands. The designation process includes peer 
review and public comment on the identified features and lands. This 
process is valuable to land owners and managers in developing 
conservation management plans for identified lands, as well as any 
other occupied habitat or suitable habitat that may not have been 
included in the Service's determination of essential habitat.
    However, the designation of critical habitat does not require that 
any management or recovery actions take place on the lands included in 
the designation. Even in cases where consultation has been initiated 
under section 7(a)(2) of the Act, the end result of consultation is to 
avoid jeopardy to the species and adverse modification of its critical 
habitat, but not specifically to manage remaining lands or institute 
recovery actions on remaining lands. Conversely, management plans 
institute intentional, proactive actions over the lands they encompass 
to remove or reduce known threats to a species or its habitat and, 
therefore, implement recovery actions. We believe that the

[[Page 78460]]

conservation of a species and its habitat that could be achieved 
through the designation of critical habitat, in some cases, is less 
than the conservation that could be achieved through the implementation 
of a management plan that includes species-specific provisions and 
considers enhancement or recovery of listed species as the management 
standard over the same lands. Consequently, implementation of any HCP 
or management plan that considers enhancement or recovery as the 
management standard will often provide as much or more benefit than a 
consultation for critical habitat designation conducted under the 
standards required by the Ninth Circuit in the Gifford Pinchot 
decision.

Educational Benefits

    A benefit of including lands in critical habitat is that 
designation of critical habitat serves to educate landowners, State and 
local governments, and the public regarding the potential conservation 
value of an area. This helps focus and promote conservation efforts by 
other parties by clearly delineating areas of high conservation value 
for the PMJM. Because the critical habitat process includes a public 
comment period, opportunities for public hearings, and announcements 
through local venues, including radio and other news sources, the 
designation of critical habitat provides numerous occasions for public 
education and involvement. Through these outreach opportunities, land 
owners, State agencies, and local governments can become more aware of 
the plight of listed species and conservation actions needed to aid in 
species recovery. Through the critical habitat process, State agencies 
and local governments may become aware of areas that could be conserved 
under State laws, local ordinances, or specific management plans.
Benefits of Exclusion
    When considering the benefits of exclusion, we consider, among 
other things, whether exclusion of a specific area is likely to result 
in conservation; the continuation, strengthening, or encouragement of 
partnerships; or implementation of a management plan that provides 
equal to or more conservation than a critical habitat designation would 
provide.
    When we evaluate the existence of a conservation plan to consider 
the benefits of exclusion, we consider a variety of factors, including 
but not limited to, whether the plan is finalized; how it provides for 
the conservation of the essential physical and biological features; 
whether there is a reasonable expectation that the conservation 
management strategies and actions contained in a management plan will 
be implemented into the future; whether the conservation strategies in 
the plan are likely to be effective; and whether the plan contains a 
monitoring program or adaptive management to ensure that the 
conservation measures are effective and can be adapted in the future in 
response to new information.
    After evaluating the benefits of inclusion and the benefits of 
exclusion, we carefully weigh the two sides to determine whether the 
benefits of exclusion outweigh those of inclusion. If we determine that 
they do, we then determine whether exclusion would result in 
extinction. If exclusion of an area from critical habitat would result 
in extinction, we will not exclude it from the designation.
Conservation Partnerships on Non-Federal Lands
    Most federally listed species in the United States will not recover 
without cooperation of non-Federal landowners. More than 60 percent of 
the United States is privately owned (National Wilderness Institute 
1995), and at least 80 percent of endangered or threatened species 
occur either partially or solely on private lands (Crouse et al. 2002, 
p. 720). Stein et al. (1995, p. 400) found that only about 12 percent 
of listed species were found almost exclusively on Federal lands (90 to 
100 percent of their known occurrences restricted to Federal lands) and 
that 50 percent of federally listed species are not known to occur on 
Federal lands at all.
    Given the distribution of listed species with respect to land 
ownership, conservation of listed species in many parts of the United 
States is dependent upon working partnerships with a wide variety of 
entities and the voluntary cooperation of many non-Federal landowners 
(Wilcove and Chen 1998, p. 1407; Crouse et al. 2002, p. 720; James 
2002, p. 271). Building partnerships and promoting voluntary 
cooperation of landowners are essential to understanding the status of 
species on non-Federal lands, and are necessary to implement recovery 
actions such as reintroducing listed species, habitat restoration, and 
habitat protection.
    Many non-Federal landowners derive satisfaction from contributing 
to endangered species recovery. We promote these private-sector efforts 
through the Department of the Interior's Cooperative Conservation 
philosophy. Conservation agreements with non-Federal landowners (safe 
harbor agreements, other conservation agreements, easements, and State 
and local regulations) enhance species conservation by extending 
species protections beyond those available through section 7 
consultations. We encourage non-Federal landowners to enter into 
conservation agreements, based on a view that we can achieve greater 
species conservation on non-Federal land through such partnerships than 
we can through regulatory methods (December 2, 1996; 61 FR 63854).
    As discussed above, consultation under section 7(a)(2) of the Act, 
and the duty to avoid jeopardy to a listed species and adverse 
modification of designated critical habitat, is only triggered where 
Federal agency action is involved. In the absence of Federal agency 
action, the primary regulatory restriction applicable to non-Federal 
landowners is the prohibition against take of listed animal species 
under section 9 of the Act. In order to take listed animal species 
where no independent Federal action is involved that would trigger 
section 7 consultation, a private landowner must obtain an incidental 
take permit under section 10 of the Act.
    However, many private landowners are wary of possible consequences 
of encouraging endangered species to their property. Mounting evidence 
suggests that some regulatory actions by the Federal government, while 
well-intentioned and required by law, can (under certain circumstances) 
have unintended negative consequences for the conservation of species 
on private lands (Wilcove et al. 1996, pp. 5-6; Bean 2002, pp. 2-3; 
Conner and Mathews 2002, pp. 1-2; James 2002, pp. 270-271; Koch 2002, 
pp. 2-3; Brook et al. 2003, pp. 1639-1643). Many landowners fear a 
decline in their property value due to real or perceived restrictions 
on land-use options where endangered or threatened species are found. 
Consequently, harboring endangered species is viewed by many landowners 
as a liability. This holds true for PMJM presence on private lands in 
Colorado. This perception results in anti-conservation incentives 
because maintaining habitats that harbor endangered species represents 
a risk to future economic opportunities (Main et al. 1999, pp. 1264-
1265; Brook et al. 2003, pp. 1644-1648). We attempt to ease these 
concerns through communication and outreach with landowners; however, 
we recognize that these efforts are not always successful.
    The purpose of designating critical habitat is to contribute to the 
conservation of endangered and threatened species and the ecosystems 
upon which they depend. The outcome

[[Page 78461]]

of the designation, triggering regulatory requirements for actions 
funded, authorized, or carried out by Federal agencies under section 
7(a)(2) of the Act, can sometimes be counterproductive to its intended 
purpose on non-Federal lands. In cases where conservation actions are 
currently employed but anxiety regarding the potential impacts of 
critical habitat designation exists, we may find that excluding non-
Federal lands from critical habitat designation results in improved 
partnerships and conservation efforts.

Benefits of Excluding Lands With Habitat Conservation Plans

    The benefits of excluding lands with approved HCPs from critical 
habitat designation, such as HCPs that cover the PMJM, include 
relieving landowners, communities, and counties of any additional 
regulatory burden that might be imposed as a result of the critical 
habitat designation. Many HCPs take years to develop, and upon 
completion, are consistent with the recovery objectives for listed 
species that are covered within the plan area. Many HCPs also provide 
conservation benefits to unlisted sensitive species.
    A related benefit of excluding lands covered by approved HCPs from 
critical habitat designation is the unhindered, continued ability it 
gives us to seek new partnerships with future plan participants, 
including States, counties, local jurisdictions, conservation 
organizations, and private landowners, which together can implement 
conservation actions that we would be unable to accomplish otherwise. 
The HCPs often cover a wide range of species, including listed plant 
species and species that are not State or federally listed and would 
otherwise receive little protection from development. By excluding 
these lands, we preserve our current partnerships and encourage 
additional conservation actions in the future.
    We also note that permit issuance in association with HCP 
applications requires consultation under section 7(a)(2) of the Act, 
which would include the review of the effects of all HCP-covered 
activities that might adversely impact the species under a jeopardy 
standard, including possibly significant habitat modification (see 
definition of ``harm'' at 50 CFR 17.3), even without the critical 
habitat designation. In addition, all other Federal actions that may 
affect the listed species would still require consultation under 
section 7(a)(2) of the Act, and we would review these actions for 
possibly significant habitat modification in accordance with the 
definition of harm referenced above.
Habitat Conservation Plans Evaluated for Exclusion
    The information provided in the previous section applies to the 
following analysis of exclusions under section (4)(b)(2) of the Act. 
Portions of the revised critical habitat units and their subunits 
warrant exclusion from the designation of revised critical habitat 
under section 4(b)(2) of the Act based on the partnerships, management, 
and protection afforded under these approved and legally operative 
HCPs.
    We consider a current plan (HCPs as well as other types) to provide 
adequate management or protection for PMJM and its habitat if it meets 
the following criteria:
    (1) The plan is complete and provides the same or better level of 
protection from adverse modification or destruction than that provided 
through a consultation under section 7 of the Act;
    (2) There is a reasonable expectation that the conservation 
management strategies and actions will be implemented for the 
foreseeable future and be effective, based on past practices, written 
guidance, or regulations; and
    (3) The plan provides adaptive management and conservation 
strategies and measures consistent with currently accepted principles 
of conservation biology.
    Section 10(a)(1)(B) of the Act authorizes us to issue to non-
Federal entities a permit for the incidental take of endangered and 
threatened species. This permit allows a non-Federal landowner to 
proceed with an activity that is legal in all other respects, but that 
results in the incidental taking of a listed species (i.e., take that 
is incidental to, and not the purpose of, the carrying out of an 
otherwise lawful activity). The Act specifies that an application for 
an incidental take permit must be accompanied by a habitat conservation 
plan (HCP), and specifies the content of such a plan. The purpose of 
conservation agreements is to describe and ensure that the effects of 
the permitted action on covered species are adequately minimized and 
mitigated, and that the action does not appreciably reduce the survival 
and recovery of the species. In our assessment of conservation 
agreements associated with this final rulemaking, the analysis required 
for these types of exclusions involves careful consideration of the 
benefits of designation versus the benefits of exclusion. The benefits 
of designation typically arise from additional section 7 protections, 
as well as enhanced public awareness once specific areas are identified 
as critical habitat. The benefits of exclusion generally relate to 
relieving regulatory burdens on existing conservation partners, 
maintaining good working relationships with them, and encouraging the 
development of new partnerships.
    We have weighed the benefits of excluding lands in the following 
HCPs from critical habitat against the benefits of inclusion. We 
determined that the benefits of excluding the lands covered by the 
Denver Water HCP, Struthers Ranch HCP, Eagle's Nest Open Space HCP, the 
Lefever Property HCP, and the Dahle Property HCP from designation as 
PMJM critical habitat outweigh the benefits of including these areas 
and that these exclusions would not result in extinction of the PMJM. 
Thus, as allowed by section 4(b)(2) of the Act, we have excluded them 
from the critical habitat designation.

Denver Water Habitat Conservation Plan

    On May 1, 2003, we issued a section 10 incidental take permit to 
Denver Water for the Denver Water HCP (Service 2003b). This permit 
covers the PMJM. Denver Water owns various properties (including 
easements), facilities, and infrastructure within the SPR in Colorado 
where the PMJM is listed. The Denver Water HCP covers the water 
facilities and infrastructure owned and operated by Denver Water, 
including: The Foothills, Marston, and Moffat treatment plants; 17 pump 
stations; 29 treated water storage reservoirs; and 2,464 mi (3,968 km) 
of pipe. The permit area includes approximately 6,000 ac (2,700 ha) of 
occupied and potential PMJM habitat on Denver Water properties in 
Boulder, Jefferson, and Douglas Counties. Denver Water properties 
covered by the HCP include portions of Units 5, 7, 9, and 10 proposed 
as revised critical habitat.
    The HCP promotes implementation of applicable best management 
practices to benefit the PMJM that avoid, minimize, and eliminate 
impacts to occupied and potential PMJM habitat. Where unavoidable 
impacts occur, Denver Water conducts mitigation as required in the HCP. 
Denver Water is authorized to take up to 25 ac (10 ha) of occupied and 
potential habitat through impacts from the covered activities at any 
one time with a maximum of 75 ac (30 ha) total disturbed over the 30-
year term of the HCP.
    This HCP provides long-term assurances that Denver Water's covered 
activities are permitted and in compliance with the Act and provides 
the Service with a tool to minimize and

[[Page 78462]]

mitigate take on occupied and potential habitat. To accomplish these 
goals, the plan requires the following special management and 
protection:
    (a) Before conducting a covered activity (principally operations 
and maintenance activities) on occupied and potential habitat, Denver 
Water will determine whether avoidance and minimization efforts are 
applicable, practicable, and can be used to avoid, reduce, or eliminate 
take. Generally, the use of best management practices will be the most 
practicable avoidance or minimization tool. Appendix 5 of the HCP lists 
best management practices that may be applicable to Denver Water's 
routine operation and maintenance activities and projects. In some 
cases, the use of best management practices will avoid take. In other 
situations, best management practices will minimize take. Where take 
still results, mitigation will be used to offset the impacts.
    (b) As required by section 10 regulations (50 CFR 17.22), the HCP 
requires Denver Water to perform compliance monitoring and 
effectiveness monitoring to determine whether the terms and conditions 
of the HCP are being met. Monitoring activities include: Document pre- 
and post-impact site conditions; determine the extent of take of 
occupied and potential habitat; determine the success of PMJM habitat 
revegetation efforts; report on additional Denver Water actions, 
including initiation of mitigation, discussion of best management 
practices utilized, if any, and other management decisions that address 
implementation of the HCP; hold an annual meeting between Denver Water 
and the Service; and prepare an annual monitoring report.
    (c) Adaptive management will be employed to gain new data, or 
research new information regarding the biology of the PMJM. The use of 
adaptive management in areas of questionable PMJM habitat suitability, 
PMJM use, or PMJM presence will likely increase the potential for 
success within the HCP and increase the potential for new and useful 
information on PMJM biology to be acquired.
    (d) The HCP will result in the protection of over 6,000 ac (2,400 
ha) of potential and occupied habitat. Denver Water must limit 
temporary impacts to 25 ac (10 ha) of occupied and potential habitat at 
any one time. Temporary impacts will not exceed 75 ac (30 ha) over the 
term of the HCP. Denver Water will also track all impacts, restore 
disturbed vegetation, and track all successful restorations to ensure 
the above limits are not exceeded.
    (e) To offset foreseeable permanent impacts to 1 ac (0.4 ha) of 
habitat, Denver Water will create 0.25 ac (0.10 ha) of riparian shrub, 
create 2.25 ac (0.91 ha) of upland occupied and potential habitat, and 
revegetate a number of trails and dirt roads. Should permanent impacts 
exceed the 1.0 ac (0.4 ha) (this HCP covers a maximum of 10 ac (4 ha) 
of permanent impacts), Denver Water will mitigate this through: A 
conservation easement at a ratio of 8:1; by enhancements at a ratio of 
2:1; or a combination of preservation at 6:1 and enhancements at 1:1.
    (f) Other mitigation includes: Weed management; education, 
training, and the distribution of information to Denver Water employees 
to promote avoidance, minimization, or best management practices as 
applicable and practicable; restoration of habitat linkage corridors; 
population monitoring and research; and provision of trapping data to 
the Service.
    Denver Water provides annual reports to the Service of activities 
conducted under the HCP. These reports document that conservation and 
management have been effective and consistent with provisions of the 
HCP. We believe that the Denver Water HCP is protective of the PMJM, is 
likely to be effective into the future, and is consistent with our 
regulatory objectives for protection of PMJM.
Section 4(b)(2) Weighing Analysis
    Denver Water controls a large complex of treatment plants, pump 
stations, pipelines, and reservoirs, some including habitat occupied by 
the PMJM. Through their HCP, Denver Water agreed to follow best 
management practices to benefit the PMJM on 6,000 ac (2,700 ha) of 
potential PMJM habitat, whether the PMJM is present or not. The 
principal benefit of any designated critical habitat is that Federal 
activities that may affect critical habitat require consultation under 
section 7 of the Act. There is little benefit to designating critical 
habitat on Denver Water properties because: (a) Denver Water has an HCP 
in place covering the same properties proposed for designation; (b) 
Denver Water is a private landowner conducting primarily private (non-
Federal) actions in these areas; (c) less than 240 ac (100 ha) of the 
Denver Water HCP overlaps with areas proposed as critical habitat (the 
HCP covers a much larger area than would have been covered on Denver 
Water lands by the proposed critical habitat); (d) educational benefits 
from designation of critical habitat on areas within the Denver Water 
HCP (through mapping of essential habitat) would be minimal, as the 
areas in question are owned or leased by Denver Water, and Denver Water 
is well aware of the value to the PMJM of those areas proposed as 
critical habitat; (e) designation of critical habitat on private 
property may discourage private landowners from participating in an 
HCP; and (f) beyond regulatory benefits of critical habitat 
designation, we know of no additional protections (such as additional 
Federal or State laws or regulations) that would be triggered by 
critical habitat designation.
    The benefits of exclusion on Denver water properties, however, are 
that: (a) Denver Water's HCP will provide greater assurances and 
conservation benefits to the PMJM than critical habitat designation, 
because the HCP will assure the long-term protection (totaling 30 
years, after which it may be extended) and management of the species 
and its habitat, with funding, through the standards in the HCP; (b) 
exclusion of properties within Denver Water's HCP reduces the 
requirements for additional regulatory review and associated permitting 
costs (delays, administrative costs, consulting costs, and costs of 
developing additional conservation measures); (c) exclusion of critical 
habitat will allow more flexibility to a municipal water supplier with 
private lands and privately owned facilities to operate as needed in 
order to meet its mission of supplying water to its customers; and (d) 
Denver Water's HCP provides an integrated and comprehensive approach to 
species conservation, rather than the piecemeal approach of multiple 
section 7 consultations that only address activities with a Federal 
nexus.
    Development and implementation of this HCP has promoted a 
conservation partnership between Denver Water and the Service and 
benefitted the PMJM. Exclusion of areas within the HCP from proposed 
critical habitat would preserve this current partnership and encourage 
future cooperation on projects and programs effecting the PMJM, other 
listed species, and a broad array of fish and wildlife resources.
    After evaluating the benefits of exclusion and the benefits of 
inclusion, we have determined that the benefits of exclusion outweigh 
those of inclusion.
Exclusion Will Not Result in Extinction of the Species
    The HCP covers only small portions of four proposed critical 
habitat units that total over 10,000 ac (4,000 ha). The HCP allows, at 
maximum, 10 ac (4 ha) of permanent impacts through the 30-year life of 
the permit. Both permanent and temporary impacts will be mitigated

[[Page 78463]]

as discussed above. We conclude that exclusion will not result in 
extinction of the PMJM, nor will it preclude conservation or recovery 
of the species.

Struthers Ranch Habitat Conservation Plan

    On December 12, 2003, we issued a section 10 incidental take permit 
covering the PMJM for the Struthers Ranch residential development along 
Black Forest Creek, El Paso County, consistent with the Struthers Ranch 
HCP (Service 2003c). The site supported approximately 49 ac (20 ha) of 
PMJM habitat. Parts of the Struthers Ranch property are within Unit 11 
of the area proposed as revised critical habitat. Flooding has heavily 
impacted the middle and upper portions of Black Forest Creek. A 1999 
flood event inundated the middle fork and deposited a large amount of 
sand and silt downstream. The HCP was designed to minimize the 
possibility of future severe flooding events, substantially improve 
remaining PMJM habitat, and minimize adverse effects resulting from 
developed areas nearby. Under the HCP, approximately 35.5 ac (14.4 ha) 
of undeveloped land along Black Forest Creek was withdrawn from cattle 
grazing, was returned to a more natural condition, and is maintained as 
a preserve with conservation measures to restore and enhance vegetation 
for wildlife. An adaptive management strategy was addressed in the HCP. 
Monitoring has documented the successful restoration of the property in 
accordance with provisions of the HCP. Lands preserved as PMJM habitat 
are deed-restricted and managed for the PMJM. The deed restriction 
prohibits any activities that would adversely impact PMJM habitat. 
Conservation and management has been effective and consistent with 
provisions of the HCP. We conclude that the HCP is protective of the 
PMJM, is likely to be effective into the future, and is consistent with 
our regulatory objectives.
Section 4(b)(2) Weighing Analysis
    Through their HCP, Struther's Ranch agreed to follow best 
management practices to benefit the PMJM on 35.5 ac (14.4 ha) of PMJM 
habitat. The principal benefit of any designated critical habitat is 
that Federal activities that may affect the habitat require 
consultation under section 7 of the Act. There is little benefit to 
designating critical habitat on Struther's Ranch property because: (a) 
An HCP is in place covering the same area proposed for designation; (b) 
Struther's Ranch is private land with primarily private (non-Federal) 
actions in this area; (c) the area covered by the HCP encompasses only 
a small fraction of a unit (i.e., most of the designation in this unit 
will remain intact); (d) educational benefits from designation of 
critical habitat on areas within the Struther's Ranch HCP (through 
mapping of essential habitat) would be minimal, as the owners of the 
area in question are well aware of the value to the PMJM of the area 
proposed as critical habitat; (e) designation of critical habitat on 
private property may discourage private landowners from participating 
in an HCP; and (f) beyond regulatory benefits of critical habitat 
designation, we know of no additional protections (such as additional 
Federal or State laws or regulations) that would be triggered by 
critical habitat designation.
    The benefits of exclusion of the Struther's Ranch HCP land are: (a) 
The Struther's Ranch HCP will provide greater assurances and 
conservation benefits to the PMJM than critical habitat designation, 
because the HCP assures the area is deed restricted and managed for the 
PMJM; and (b) The Struther's Ranch HCP provides an integrated and 
comprehensive approach to species conservation on site rather than the 
piecemeal approaches of section 7 consultation that only addresses 
activities with a Federal nexus.
    After evaluating the benefits of exclusion and the benefits of 
inclusion, we have determined that the benefits of exclusion outweigh 
those of inclusion.
Exclusion Will Not Result in Extinction of the Species
    Habitat impacts allowed under this HCP have already occurred. We 
conclude that exclusion will not result in extinction of the PMJM, nor 
will it preclude conservation or recovery of the species.

Eagle's Nest Open Space Habitat Conservation Plan

    On August 5, 2004, we issued Larimer County a section 10 incidental 
take permit covering the PMJM consistent with the county's HCP for 
their Eagle's Nest Open Space (ENOS) property, located in the Laramie 
Foothills region of Larimer County (Service 2004b). The ENOS is 
partially within Unit 1 of the area that was proposed as revised 
critical habitat. The ENOS encompasses 755 ac (306 ha) of rolling 
foothills and steep slopes and includes 1.0 mi (1.6 km) of the North 
Fork of the Cache la Poudre River. There are approximately 261 ac (106 
ha) of PMJM habitat on the ENOS, the vast majority of which is managed 
for PMJM conservation under the HCP. Less than 3 ac (1 ha) can be 
permanently affected under the ENOS HCP for a natural-surface hiking 
and equestrian trail, and cattle access to the river. Agreed-upon 
habitat improvement for the PMJM included fencing off of riparian areas 
to control cattle grazing, shrub planting, limiting management 
activities during the PMJM active season, and control of public access 
and allowed activities. This area is protected as open space by the 
Larimer County Open Lands program. The protection and enhancement of 
wildlife habitat is one of the primary goals on ENOS. The area is used 
for educational programs by the county, demonstrating PMJM and riparian 
habitat management. Mitigation is paid for through the county's Help 
Preserve Open Space Sales Tax revenues guaranteed through 2018. Success 
criteria, monitoring, and a process to address unforeseeable events are 
addressed in the HCP. Monitoring reports submitted from 2004 through 
2008 documented the success of mitigation efforts.
Section 4(b)(2) Weighing Analysis
    Through their HCP, Larimer County agreed to follow best management 
practices to benefit the PMJM through protection and management of 261 
ac (106 ha) of PMJM habitat. The principal benefit of any designated 
critical habitat is that Federal activities that may affect the habitat 
require consultation under section 7 of the Act. There is little 
benefit to designating critical habitat on ENOS property because: (a) 
An HCP is in place covering the same area proposed for designation; (b) 
ENOS is owned by Larimer County with primarily private (non-Federal) 
actions in this area; (c) the area covered by the HCP encompasses only 
a small fraction of Unit 1; (d) educational benefits from designation 
of critical habitat on areas within the ENOS HCP (through mapping of 
essential habitat) would be minimal, as Larimer County is aware of the 
value to the PMJM of the area proposed as critical habitat and is using 
it to educate the public about PMJM and its habitat; (e) designation of 
critical habitat on non-Federal property may discourage local 
government from participating in an HCP; and (f) beyond regulatory 
benefits of critical habitat designation, we know of no additional 
protections (such as additional Federal or State laws or regulations) 
that would be triggered by critical habitat designation.
    The benefits of exclusion of the ENOS HCP land, however, are that: 
(a) The ENOS HCP will provide greater assurances and conservation 
benefits to the PMJM than critical habitat designation because the HCP 
will assure the area is managed for the PMJM; (b)

[[Page 78464]]

The ENOS HCP provides an integrated and comprehensive approach to 
species conservation rather than the piecemeal approach of section 7 
consultations that only addresses activities with a Federal nexus; and 
(c) development and implementation of this HCP has promoted a 
conservation partnership between Larimer County and the Service, and 
has benefitted the PMJM. Exclusion of areas within the HCP from 
proposed critical habitat would preserve this current partnership and 
encourage future cooperation on projects and programs effecting the 
PMJM, other listed species, and a broad array of fish and wildlife 
resources.
    After evaluating the benefits of exclusion and the benefits of 
inclusion, we have determined that the benefits of exclusion outweigh 
those of inclusion.
Exclusion Will Not Result in Extinction of the Species
    Impacts to habitat (3 ac (1 ha)) allowed by the ENOS HCP have 
already occurred. Remaining PMJM habitat is managed as described above. 
We conclude that exclusion will not result in extinction of the PMJM, 
nor will it preclude conservation or recovery of the species.

Other Habitat Conservation Plan Lands

    On November 19, 2002, we approved an HCP, and we issued a section 
10 incidental take permit covering the PMJM for a single family 
residence on the Lefever Property along Black Squirrel Creek in Black 
Forest, El Paso County (Service 2002b). The Lefever Property is within 
Unit 11 of the area proposed as revised critical habitat. Under the 
HCP, 0.56 ac (0.25 ha) of PMJM habitat was permitted to be disturbed, 
and 4.52 ac (1.83 ha) of the property was placed in a conservation 
easement and deeded to El Paso County, to be managed as foraging 
habitat for the PMJM according to specific requirements laid out in the 
HCP. The following activities are expressly prohibited by the property 
easement: Construction or reconstruction of any building or other 
structure or improvement on portions of the property; any division or 
subdivision of the title to the property; commercial timber harvesting; 
mining or extraction of soil, sand, gravel, rock, oil, natural gas, 
fuel, or any other mineral substance; paving or otherwise covering with 
concrete, asphalt, or any other paving material; and the dumping or 
uncontained accumulation of any trash, refuse, or debris on the 
property. As further compensation for the impacted habitat, 0.89 ac 
(0.36 ha) of the 4.52 ac (1.83 ha) were planted with 100 shrubs to 
enhance PMJM habitat. Three years of monitoring demonstrated success of 
the planting effort. The permit expires November 19, 2012, but the 
conservation easement and requirements of the HCP call for the property 
to be managed consistent with the needs of the PMJM in perpetuity.
    On July 23, 2002, we approved a low-effect HCP, and we issued a 
section 10 incidental take permit covering the PMJM for a single family 
residence on the Dahle Property, Thunderbird Estates, near Monument 
Creek in Colorado Springs, El Paso County (Service 2002c). The Dahle 
Property is within Unit 11 of the area proposed as revised critical 
habitat. Under the HCP, 0.15 ac (0.060 ha) of upland PMJM habitat was 
permitted to be disturbed for the construction of a single-family 
residence and 0.5 ac (0.2 ha) of the property was preserved in a native 
and unmowed condition and enhanced through weed control and Salix 
(willow) planting. Required monitoring has documented success of these 
measures. The take permit expired July 29, 2007; however, preservation 
of PMJM habitat continues in perpetuity.
Section 4(b)(2) Weighing Analysis
    The Lefever Property and Dahle Property HCPs address single 
residences on small properties. The applicants expended significant 
resources to develop these HCPs. Relieving these landowners of any real 
or perceived regulatory burden that might accompany designation of 
critical habitat supports partnerships between the private property 
owners and the Service. The principal benefit of any designated 
critical habitat is that Federal activities that may affect the habitat 
require consultation under section 7 of the Act. There is little 
benefit to designating critical habitat on properties covered by these 
two HCPs because: (a) The HCPs cover the same area proposed for 
designation; (b) it is unlikely that future Federal actions will occur 
on these small private areas; (c) the areas covered by the HCPs 
encompass a small fraction of Unit 11; (d) educational benefits from 
designation of critical habitat on areas within the HCPs (through 
mapping of essential habitat) would be minimal, as the two single 
landowners are aware of the value to the PMJM of the area proposed as 
critical habitat; (e) designation of critical habitat on non-Federal 
property may discourage private entities from participating in an HCP; 
and (f) beyond regulatory benefits of critical habitat designation, we 
know of no additional protections (such as additional Federal or State 
laws or regulations) that would be triggered by critical habitat 
designation.
    The benefits of exclusion of land in these two HCPs, however, are 
that: (a) The HCPs will provide greater assurances and conservation 
benefits to the PMJM than critical habitat designation because the HCPs 
assure the areas are managed to preserve habitat for the PMJM; and (b) 
development and implementation of these HCPs has promoted a 
conservation partnership between private landowners and the Service, 
and has benefitted the PMJM. Exclusion of areas within the HCPs from 
proposed critical habitat may serve as an example to private landowners 
and encourage future cooperation on projects and programs effecting the 
PMJM, other listed species, and other fish and wildlife resources.
    After evaluating the benefits of exclusion and the benefits of 
inclusion, we have determined that the benefits of exclusion outweigh 
those of inclusion.
Exclusion Will Not Result in Extinction of the Species
    The Lefever Property and Dahle Property HCP permits allowed 0.71 ac 
(0.31 ha) of permanent habitat impacts, which have already occurred. 
Offsets and mitigation included additional lands that have been set 
aside for the PMJM, with habitat improvement and conservation easement, 
as described above. We conclude that exclusion of the lands in these 
HCPs will not result in extinction of the PMJM, nor will it preclude 
conservation or recovery of the species.
Summary of Habitat Conservation Plan Lands Excluded
    Based on our evaluation of special management considerations and 
protection provided by the Denver Water HCP, the Struthers Ranch HCP, 
the Eagle's Nest Open Space HCP, the Lefever Property HCP, and the 
Dahle Property HCP, and in light of the definition of critical habitat 
in section 3(5)(A) of the Act, we have considered, but are not, 
designating these areas as revised critical habitat. We believe that 
these HCPs meet the criteria used by the Service to determine whether a 
plan provides adequate special management or protection to a listed 
species. The conservation strategies and measures are likely to be 
effective, because they were developed based on the best scientific 
data available and they required monitoring and reporting to ensure 
compliance and success. The lands excluded total 6,315.73 ac (2,328.34 
ha), in portions of Units 1, 5, 7, 9, 10, and 11.

Required Determinations

Regulatory Planning and Review--Executive Order 12866

    The Office of Management and Budget (OMB) has determined that this 
rule is not significant. OMB bases its determination upon the following 
four criteria:
    (1) Whether the rule will have an annual effect of $100 million or 
more on the economy or adversely affect an economic sector, 
productivity, jobs, the environment, or other units of the government.
    (2) Whether the rule will create inconsistencies with other Federal 
agencies' actions.
    (3) Whether the rule will materially affect entitlements, grants, 
user fees, loan programs, or the rights and obligations of their 
recipients.
    (4) Whether the rule raises novel legal or policy issues.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (RFA, 5 U.S.C. 601 et seq.), 
as amended by the Small Business Regulatory Enforcement Fairness Act 
(SBREFA) of 1996 (5 U.S.C. 801 et seq.), whenever an agency must 
publish a notice of rulemaking for any proposed or final rule, it must 
prepare and make available for public comment a regulatory flexibility 
analysis that describes the effects of the rule on small entities 
(i.e., small businesses, small organizations, and small government 
jurisdictions). However, no regulatory flexibility analysis is required 
if the head of the agency certifies the rule will not have a 
significant economic impact on a substantial number of small entities. 
The SBREFA amended the RFA to require Federal agencies to provide a 
certification statement of the factual basis for certifying that the 
rule will not have a significant economic impact on a substantial 
number of small entities. As part of our DEA for the proposed 
designation, we provided our initial regulatory flexibility analysis 
for determining whether the proposed rule would result in a significant 
economic impact on a substantial number of small entities. Based on 
comments we received, we have revised the FEA and finalized our 
regulatory flexibility analysis (FRFA), as part of our final 
rulemaking. In this final rule, we are certifying that the critical 
habitat designation for the PMJM will not have a significant economic 
impact on a substantial number of small entities. The following 
discussion explains our rationale.
    According to the Small Business Administration, small entities 
include small organizations, such as independent nonprofit 
organizations, and small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents, as well as small businesses (13 CFR 121.201). Small 
businesses include manufacturing and mining concerns with fewer than 
500 employees, wholesale trade entities with fewer than 100 employees, 
retail and service businesses with less than $5 million in annual 
sales, general and heavy construction businesses with less than $27.5 
million in annual business, special trade contractors doing less than 
$11.5 million in annual business, and agricultural businesses with 
annual sales less than $750,000. To determine if potential economic 
impacts to these small entities are significant, we considered the 
types of activities that might trigger regulatory impacts under the 
rule, as well as the types of project modifications that may result. In 
general, the term ``significant economic impact'' is meant to apply to 
a typical small business firm's business operations.
    To determine if the final designation of revised critical habitat 
for the PMJM would affect a substantial number of small entities, we 
considered the number of small entities affected within particular 
types of economic activities (e.g., housing development, grazing, oil 
and gas production, timber harvesting). In order to determine whether 
it is appropriate for our agency to certify that this rule will not 
have a significant economic impact on a substantial number of small 
entities, we considered each industry or category individually. 
However, the SBREFA does not explicitly define substantial number or 
significant economic impact. Consequently, to assess whether a 
substantial number of small entities is affected by this revised 
designation, this analysis considers the relative number of small 
entities likely to be impacted in an area. In some circumstances, 
especially with critical habitat designations of limited extent, we may 
aggregate across all industries and consider whether the total number 
of small entities affected is substantial. In estimating the numbers of 
small entities potentially affected, we also considered whether their 
activities have any Federal involvement. Critical habitat designation 
will not affect activities that do not have any Federal involvement; 
designation of critical habitat affects activities conducted, funded, 
permitted, or authorized by Federal agencies.
    Under the Act, designation of critical habitat only affects 
activities carried out, funded, or permitted by Federal agencies. 
Following this revised critical habitat designation, Federal agencies 
must consult with us under section 7 of the Act if their activities may 
affect designated critical habitat. Consultations to avoid the 
destruction or adverse modification of critical habitat will be 
incorporated into the existing consultation process.
    Some kinds of activities are unlikely to have any Federal 
involvement and so will not result in any additional effects under the 
Act. However, there are some State laws that limit activities in 
designated critical habitat even where there is no Federal nexus. If 
there is a Federal nexus, Federal agencies will be required to consult 
with us under section 7 of the Act on activities they fund, permit, or 
carry out that may affect critical habitat. If we conclude, in a 
biological opinion, that a proposed action is likely to destroy or 
adversely modify critical habitat, we can offer ``reasonable and 
prudent alternatives.'' Reasonable and prudent alternatives are 
alternative actions that can be implemented in a manner consistent with 
the scope of the Federal agency's legal authority and jurisdiction, 
that are economically and technologically feasible, and that would 
avoid destroying or adversely modifying critical habitat.
    Within the revised critical habitat designation, the types of 
actions or authorized activities that we have identified as potential 
concerns and that may be subject to consultation under section 7 if 
there is a Federal nexus are: Residential and commercial development; 
roads/bridges, utilities, and bank stabilization projects; water supply 
development; USFS land management practices; Rocky Flats Site 
management practices; and gravel mining. As discussed in Appendix A of 
the FEA, of the activities addressed in the analysis, only residential 
and commercial development, and construction and maintenance of roads/
bridges, utilities, and bank stabilization projects, are expected to 
experience incremental, administrative consultation costs that may be 
borne by small businesses.
    Any existing and planned projects, land uses, and activities that 
could affect the revised critical habitat but have no Federal 
involvement would not require section 7 consultation with the Service, 
so they are not restricted by the requirements of the Act. Federal 
agencies may need to reinitiate a previous consultation if 
discretionary involvement or control over the Federal

[[Page 78466]]

action has been retained or is authorized by law and the activities may 
affect critical habitat.
    In the FEA, we evaluated the potential economic effects on small 
entities resulting from implementation of conservation actions related 
to the designation of critical habitat for the PMJM. Please refer to 
our FEA of the revised critical habitat designation for a more detailed 
discussion of potential economic impacts; we will summarize key points 
of the analysis below.
    The FEA, and its associated FRFA, estimate that total potential 
incremental economic impacts in areas designated as revised critical 
habitat over the next 20 years will be $2.66 million to $5.98 million 
annually, assuming a 7-percent discount rate. Approximately 96 percent 
of the incremental impacts attributed to the designation of critical 
habitat are expected to be related to section 7 consultations with 
Federal agencies for residential and commercial development. Expected 
impacts to residential and commercial development include added costs 
primarily due to administrative consultations and required 
modifications to development project scope or design, including 
mitigation (or setting aside conservation lands), habitat restoration 
and enhancement, and project delays. Small entities represent 97 
percent of all entities in the residential and commercial development 
industry that may be affected. Incremental costs also are expected 
related to road/bridge, utility, and bank stabilization construction 
and maintenance activities throughout the revised critical habitat. 
Small entities represent 90 percent of all entities in the road/bridge, 
utility, and bank stabilization construction and maintenance industries 
that may be affected. The Small Business Size Standard for the industry 
sectors that could potentially be affected by the revised critical 
habitat designation are as follows:
     New Housing Operative Builders--$33.5 million in annual 
receipts.
     Land Subdivision--$7 million in annual receipts.
     Natural Gas Distribution--500 employees.
     Water Supply and Irrigation Systems--$7 million annual 
receipts.
     Pipeline Transportation of Natural Gas--$7 million annual 
receipts.
    In addition, government entities in the area may be affected. Of 
these, approximately 70 percent are small government jurisdictions 
(i.e., cities, counties, towns, townships, villages, school districts, 
or special districts with a population of less than 50,000).
    Of principal interest is residential and commercial development, 
and associated land subdivision, as an estimated 96 percent of 
potential incremental impacts may affect that industry sector. The 
small businesses in this industry sector may bear a total of $26.2 to 
$60.3 million (at a 7-percent discount rate) in incremental impacts 
related to section 7 consultations over the next 20 years (through 
2029). However, when expressed as a percentage of a small developer's 
annual sales revenue, assuming that one small developer is required for 
each of the development projects, these monetary incremental impacts 
are likely to be small. The incremental impact due to revised critical 
habitat designation is estimated to range from $171,000 to $393,000 per 
project. An average of eight projects is anticipated to occur in 
critical habitat per year. For new home builders, estimated annual 
sales in 2007 per developer in Colorado were $6.51 million. Therefore, 
in years where a developer has a project in critical habitat, the 
estimated incremental impact represents 2.6 to 6.0 percent of that 
developer's annual sales in this industry. However, we expect these 
costs to be incurred over a period of more than one year, as most 
developments will take longer than one year to complete (i.e., if a 
project takes 2 or more years to complete, the impact as a proportion 
of revenue in any one year will be substantially less).
    For land subdividers, the FEA assumes that annual sales per 
establishment are limited to the small business threshold of $7 million 
annually. The estimated annual incremental impact therefore represents 
2.4 to 4.6 percent of a subdivider's annual sales. As discussed above, 
the incremental impact associated with each project is expected to be 
incurred over a period of more than one year. Thus, this analysis 
overstates the actual annual impact on a small entity.
    There are additional factors that may cause this analysis to 
overstate the actual impact on small residential and commercial 
developers, and on land subdividers. First, it is likely that a portion 
of the impact will be realized by landowners in the form of higher 
housing prices. The proportion of the total impact borne by landowners 
is unknown. We believe the analysis gives a high estimate of possible 
development and that it is likely the actual amount of development will 
be less. As described in Chapter 3 of the FEA, the analysis likely 
overstates the amount of development activity and, therefore, the total 
incremental impact associated with residential and commercial 
development. Lastly, anecdotal evidence and existing county building 
restrictions suggest that fewer properties within revised critical 
habitat are being developed than are quantified by the FEA. This will 
likely further reduce the annual incremental impact borne per small 
entity.
    For road/bridge, utility, and bank stabilization construction and 
maintenance, the FEA estimates that incremental impacts will range from 
$322,000 to $748,000 over 20 years, or $30,400 to $76,000 annually. 
Given an estimated average of four projects impacting critical habitat 
and requiring section 7 consultation each year, and assuming one small 
entity (municipality, wastewater district, etc.) conducts each 
activity, the impact to each small government entity involved would be 
$7,600 to $17,700.
    In summary, we have considered whether this revised designation 
will result in a significant economic impact on a substantial number of 
small entities. Given the analysis above, the expected annual impacts 
to small businesses in the affected industries are significantly less 
than the annual revenues that could be garnered by a single small 
operator in those industries, and as such, impacts are low relative to 
potential revenues. Based on the above reasoning and currently 
available information, we conclude that this rule will not have a 
significant economic impact on a substantial number of small business 
entities. Therefore, we are certifying that the revised designation of 
critical habitat for the PMJM will not have a significant economic 
impact on a substantial number of small entities.

Energy Supply, Distribution, and Use--Executive Order 13211

    On May 18, 2001, the President issued E.O. 13211 (Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use) on regulations that significantly affect energy 
supply, distribution, and use. E.O. 13211 requires agencies to prepare 
Statements of Energy Effects when undertaking certain actions. The 
Office of Management and Budget's guidance for implementing this 
Executive Order outlines nine outcomes that may constitute ``a 
significant adverse effect'' when compared to no regulatory action. The 
only criterion that may be relevant to this analysis is increases in 
the cost of energy distribution in excess of one percent. As described 
in the FEA, constructing and maintaining electrical and natural gas 
distribution and transmission systems is a type of utility project 
potentially occurring in the

[[Page 78467]]

revised critical habitat. The FEA concludes that incremental impacts 
may be incurred; however, they are unlikely to reach the threshold of 
one percent. Therefore, designation of revised critical habitat is not 
expected to lead to any adverse outcomes (such as a reduction in 
electricity production or an increase in the cost of energy production 
or distribution), and a Statement of Energy Effects is not required.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
et seq.), we make the following findings:
    (1) This rule will not produce a Federal mandate. In general, a 
Federal mandate is a provision in legislation, statute, or regulation 
that would impose an enforceable duty upon State, local, or Tribal 
governments, or the private sector, and includes both ``Federal 
intergovernmental mandates'' and ``Federal private sector mandates.'' 
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal 
intergovernmental mandate'' includes a regulation that ``would impose 
an enforceable duty upon State, local, or Tribal governments,'' with 
two exceptions. First, it excludes ``a condition of federal 
assistance.'' Second, it excludes ``a duty arising from participation 
in a voluntary Federal program,'' unless the regulation ``relates to a 
then-existing Federal program under which $500,000,000 or more is 
provided annually to State, local, and Tribal governments under 
entitlement authority,'' if the provision would ``increase the 
stringency of conditions of assistance'' or ``place caps upon, or 
otherwise decrease, the Federal Government's responsibility to provide 
funding'' and the State, local, or Tribal governments ``lack 
authority'' to adjust accordingly. At the time of enactment, these 
entitlement programs were: Medicaid; Aid to Families with Dependent 
Children work programs; Child Nutrition; Food Stamps; Social Services 
Block Grants; Vocational Rehabilitation State Grants; Foster Care, 
Adoption Assistance, and Independent Living; Family Support Welfare 
Services; and Child Support Enforcement. ``Federal private sector 
mandate'' includes a regulation that ``would impose an enforceable duty 
upon the private sector, except (i) a condition of Federal assistance; 
or (ii) a duty arising from participation in a voluntary Federal 
program.''
    The designation of critical habitat does not impose a legally 
binding duty on non-Federal government entities or private parties. 
Under the Act, the only regulatory effect is that Federal agencies must 
ensure that their actions do not destroy or adversely modify critical 
habitat under section 7. While non-Federal entities that receive 
Federal funding, assistance, or permits, or that otherwise require 
approval or authorization from a Federal agency for an action, may be 
indirectly impacted by the designation of critical habitat, the legally 
binding duty to avoid destruction or adverse modification of critical 
habitat rests squarely on the Federal agency. Furthermore, to the 
extent that non-Federal entities are indirectly impacted because they 
receive Federal assistance or participate in a voluntary Federal aid 
program, the Unfunded Mandates Reform Act would not apply, nor would 
critical habitat shift the costs of the large entitlement programs 
listed above on to State governments.
    (2) As discussed in the FEA of the designation of revised critical 
habitat for the PMJM, we do not believe that the rule will 
significantly or uniquely affect small governments because it will not 
produce a Federal mandate of $100 million or greater in any year; that 
is, it is not a ``significant regulatory action'' under the Unfunded 
Mandates Reform Act. The FEA concludes that incremental impacts may 
occur due to project modifications that may need to be made for 
development activities; however, these are not expected to affect small 
governments to the extent described above. Consequently, we do not 
believe that this final revised critical habitat designation will 
significantly or uniquely affect small government entities. As such, a 
Small Government Agency Plan is not required.

Takings--Executive Order 12630

    In accordance with E.O. 12630 (Government Actions and Interference 
with Constitutionally Protected Private Property Rights), we have 
analyzed the potential takings implications of designating critical 
habitat for the PMJM in a takings implications assessment. Critical 
habitat designation does not affect landowner actions that do not 
require Federal funding or permits, nor does it preclude development of 
habitat conservation programs or issuance of incidental take permits to 
permit actions that do require Federal funding or permits to go 
forward. The takings implications assessment concludes that this 
designation of critical habitat for the PMJM does not pose significant 
takings implications for lands within or affected by the designation.

Federalism--Executive Order 13132

    In accordance with E.O. 13132, this rule does not have significant 
Federalism effects. A Federalism assessment is not required. In keeping 
with Department of the Interior and Department of Commerce policy, we 
requested information from, and coordinated development of, our revised 
critical habitat designation with appropriate State resource agencies 
in Colorado. We received no comments from the State of Colorado or 
State resource agencies in Colorado. The designation of critical 
habitat in areas currently occupied by the PMJM may impose nominal 
additional regulatory restrictions to those currently in place and, 
therefore, may have little incremental impact on State and local 
governments and their activities. The designation may have some benefit 
to these governments, in that the areas that contain the physical and 
biological features essential to the conservation of the species are 
more clearly defined, and the PCEs of the habitat necessary to the 
conservation of the species are specifically identified. This 
information does not alter where and what federally sponsored 
activities may occur. However, it may assist local governments in long-
range planning (rather than having them wait for case-by-case section 7 
consultations to occur).

Civil Justice Reform--Executive Order 12988

    In accordance with E.O. 12988 (Civil Justice Reform), this rule 
meets the applicable standards set forth in sections 3(a) and 3(b)(2) 
of the Order. We are designating critical habitat in accordance with 
the provisions of the Act. This final rule uses standard property 
descriptions and identifies the physical and biological features 
essential to the conservation of the subspecies within the designated 
areas to assist the public in understanding the habitat needs of the 
PMJM.

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This rule does not contain any new collections of information that 
require approval by OMB under the Paperwork Reduction Act of 1995 (44 
U.S.C. 3501 et seq.). This rule will not impose recordkeeping or 
reporting requirements on State or local governments, individuals, 
businesses, or organizations. An agency may not conduct or sponsor, and 
a person is not required to respond to, a collection of information 
unless it displays a currently valid OMB control number.

National Environmental Policy Act (42 U.S.C. 4321 et seq.)

    We completed a NEPA analysis for this revised critical habitat 
designation. We notified the public of availability of the draft 
environmental assessment for the proposed rule on May 27, 2010 (75 FR 
29700. The final environmental assessment, as well as the Finding of No 
Significant Impact, is available upon request from the Field 
Supervisor, Colorado Ecological Services Office (see FOR FURTHER 
INFORMATION CONTACT section) or on our Web site at http://mountain-prairie.fws.gov/species/mammals/preble/

Government-to-Government Relationship With Tribes

    In accordance with the President's memorandum of April 29, 1994, 
Government-to-Government Relations with Native American Tribal 
Governments (59 FR 22951), E.O. 13175, the Department of the Interior's 
manual at 512 DM 2, and Secretarial Order 3206, we readily acknowledge 
our responsibility to communicate meaningfully with recognized Federal 
tribes on a government-to-government basis. In accordance with 
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights, 
Federal-Tribal Trust Responsibilities, and the Endangered Species Act), 
we readily acknowledge our responsibilities to work directly with 
Tribes in developing programs for healthy ecosystems, to acknowledge 
that tribal lands are not subject to the same controls as Federal 
public lands, to remain sensitive to Indian culture, and to make 
information available to Tribes. We determined that there are no Tribal 
lands in Colorado occupied at the time of listing that contain the 
features essential for the conservation of the PMJM, and no unoccupied 
Tribal lands that are essential for the conservation of the PMJM. 
Therefore, we are not designating critical habitat for the PMJM on 
Tribal lands.

2. In Sec.  17.95(a), revise the entry for ``Preble's Meadow Jumping 
Mouse (Zapus hudsonius preblei)'' to read as follows:


Sec.  17.95  Critical habitat--fish and wildlife.

    (a) Mammals.
* * * * *
    Preble's Meadow Jumping Mouse (Zapus hudsonius preblei)
    (1) Critical habitat units are depicted for Boulder, Broomfield, 
Douglas, El Paso, Jefferson, Larimer, and Teller Counties in Colorado 
on the maps below.
    (2) The primary constituent elements of critical habitat for the 
Preble's meadow jumping mouse are:
    (i) Riparian corridors:
    (A) Formed and maintained by normal, dynamic, geomorphological, and 
hydrological processes that create and maintain river and stream 
channels, floodplains, and floodplain benches and that promote patterns 
of vegetation favorable to the Preble's meadow jumping mouse;
    (B) Containing dense, riparian vegetation consisting of grasses, 
forbs, or shrubs, or any combination thereof, in areas along rivers and 
streams that normally provide open water through the Preble's meadow 
jumping mouse's active season; and
    (C) Including specific movement corridors that provide connectivity 
between and within populations. This may include river and stream 
reaches with minimal vegetative cover or that are armored for erosion 
control; travel ways beneath bridges, through culverts, along canals 
and ditches; and other areas that have experienced substantial human 
alteration or disturbance.
    (ii) Additional adjacent floodplain and upland habitat with limited 
human disturbance (including hayed fields, grazed pasture, other 
agricultural lands that are not plowed or disked regularly, areas that 
have been restored after past aggregate extraction, areas supporting 
recreational trails, and urban-wildland interfaces).
    (3) Critical habitat does not include buildings, roads, parking 
lots, other paved areas, lawns, other urban and suburban landscaped 
areas, regularly plowed or disked agricultural areas, and the land on 
which they are located existing within the legal boundaries on the 
effective date of this rule.
    (4) Critical habitat map units. Data layers defining map units were 
created on a base of USGS digital ortho-photo quarter-quadrangles, and 
critical habitat units were then mapped using Universal Transverse 
Mercator (UTM) Zone 15N coordinates.
