Endangered and Threatened Wildlife and Plants; Revised Critical 
Habitat for Navarretia fossalis (Spreading Navarretia)

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule; reopening of comment period.

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

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce the 
reopening of the public comment period on our June 10, 2009, proposed 
revised designation of critical habitat for Navarretia fossalis 
(spreading navarretia). We also announce the availability of a draft 
economic analysis (DEA); revisions to proposed critical habitat, 
including proposed revisions to eight subunits based on the previous 
public comment period; and an amended required determinations section 
of the proposal. We are reopening the comment period for an additional 
30 days to allow all interested parties an opportunity to comment on 
all of the above. If you submitted comments previously, you do not need 
to resubmit them because we have already incorporated them into the 
public record and will fully consider them in our final determination.

DATES: We will consider public comments received on or before May 17, 
2010. Any comments that are received after the closing date may not be 
considered in the final decision on this action.

SUPPLEMENTARY INFORMATION: 

Public Comments

    We intend that any final action resulting from the proposed rule is 
based on the best scientific data available and will be accurate and as 
effective as possible. Therefore, we request comments or information 
from other concerned government agencies, the scientific community, 
industry, or any other interested parties during this reopened comment 
period on our proposed rule to revise critical habitat for Navarretia 
fossalis (spreading navarretia), which we published in the Federal 
Register on June 10, 2009 (74 FR 27588), including the changes to 
proposed critical habitat in Subunits 1A, 1B, 3B, 5C, 5I, 6A, 6B, and 
6C, the DEA of the proposed revised designation, and the amended 
required determinations provided in this document. We are particularly 
interested in comments concerning:
    (1) The reasons why we should or should not revise the critical 
habitat under section 4 of the Endangered Species Act of 1973, as 
amended (Act) (16 U.S.C. 1531 et seq.), including whether there are 
threats to Navarretia fossalis from human activity, the type of human 
activity causing these threats, and whether the benefit of designation 
would outweigh any threats to the species caused by the designation, 
such that the designation of critical habitat is prudent.
    (2) Specific information on:
     The current amount and distribution of Navarretia fossalis 
habitat.
     Areas that provide habitat for N. fossalis that we did not 
discuss in our original proposed revised critical habitat rule or in 
this reopening of the comment period.
     Areas containing the physical and biological features 
essential to the conservation of N. fossalis that we should include in 
the revised critical habitat designation and why. Include information 
on the distribution of these essential features and what special 
management considerations or protections may be required to maintain or 
enhance them.
     Areas proposed as critical habitat that do not contain the 
physical and biological features essential for the conservation of the 
species that should not be designated as critical habitat.
     Areas not occupied at the time of listing that are 
essential to the conservation of the species and why.
    (3) Land use designations and current or planned activities in the 
areas occupied by the species, and their possible impacts on proposed 
critical habitat;
    (4) How the proposed revised critical habitat boundaries could be 
refined to more closely circumscribe landscapes identified as 
containing the physical and biological features essential to the 
conservation of the species.
     (5) Any foreseeable economic, national security, or other relevant 
impacts that may result from designating particular areas as critical 
habitat, and, in particular, any impacts to small entities (e.g., small 
businesses or small governments), and the benefits of including or 
excluding areas from the proposed revised designation that exhibit 
these impacts.
    (6) Special management considerations or protections that the 
essential physical and biological features identified in the proposed 
critical habitat may require.
    (7) Information on the extent to which the description of potential 
economic impacts in the DEA is complete and accurate.
    (8) Whether any specific subunits being proposed as critical 
habitat should be excluded under section 4(b)(2) of the Act, and 
whether the benefits of potentially excluding any particular area 
outweigh the benefits of including that area as critical habitat.
    (9) Our consideration to exclude the portion of Subunit 4E that we 
are proposing as critical habitat within the Ramona Grasslands Preserve 
under section 4(b)(2) of the Act, and whether such exclusion is 
appropriate and why;
    (10) The likelihood of adverse social reactions to the designation 
of critical habitat, and how the consequences of such reactions, if 
they occur, would relate to the conservation of the species and 
regulatory benefits of the proposed revised critical habitat 
designation.
    (11) Information on the extent to which the description of 
potential economic impacts in the DEA is complete and accurate, and 
specifically:

[[Page 19576]]

     Whether there are incremental costs of critical habitat 
designation (e.g., costs attributable solely to the designation of 
critical habitat for Navarretia fossalis) that have not been 
appropriately identified or considered in our economic analysis, 
including costs associated with future administrative costs or project 
modifications that may be required by Federal agencies related to 
section 7 consultation under the Act;
     Whether there are incremental economic benefits of 
critical habitat designation that have not been appropriately 
identified or considered in our economic analysis.
    (12) The potential effects of climate change on this species and 
its habitat and whether the critical habitat may adequately account for 
these potential effects.
    If you submitted comments or information on the proposed revised 
rule (74 FR 27588) during the initial comment period from June 10, 
2009, to August 10, 2009, please do not resubmit them. These comments 
are included in the public record for this rulemaking, and we will 
fully consider them in the preparation of our final determination. Our 
final determination concerning the revised critical habitat for 
Navarretia fossalis will take into consideration all written comments 
and any additional information we receive during both comment periods. 
On the basis of public comments, we may, during the development of our 
final determination, find that areas within the proposed revised 
critical habitat designation do not meet the definition of critical 
habitat, that some modifications to the described boundaries are 
appropriate, or that areas may or may not be appropriate for exclusion 
under section 4(b)(2) of the Act.
    You may submit your comments and materials concerning our proposed 
rule, the associated DEA, our changes to subunits and considered 
exclusions as identified in this document, and our amended required 
determinations section by one of the methods listed in the ADDRESSES 
section.
    If you submit a comment via http://www.regulations.gov, your entire 
submission--including any personal identifying information--will be 
posted on the website. If your submission is made via a hard copy that 
includes personal identifying information, you may request at the top 
of your document that we withhold this information from public review. 
However, we cannot guarantee that we will be able to do so. We will 
post all hard copy comments on http://www.regulations.gov. Please 
include sufficient information with your comments to allow us to verify 
any scientific or commercial information you include.
    Comments and materials we receive, as well as supporting 
documentation used to prepare this notice, will be available for public 
inspection at http://www.regulations.gov, or by appointment, during 
normal business hours, at the U.S. Fish and Wildlife Service, Carlsbad 
Fish and Wildlife Office (see FOR FURTHER INFORMATION CONTACT). You may 
obtain copies of the proposed revision of critical habitat (74 FR 
27588) and the DEA on the Internet at http://www.regulations.gov at 
Docket No. FWS-R8-ES-2009-0038, or by mail from the Carlsbad Fish and 
Wildlife Office (see FOR FURTHER INFORMATION CONTACT).

Background

    It is our intent to discuss only those topics directly relevant to 
the proposed revised designation of critical habitat for Navarretia 
fossalis in this notice. For more information on previous Federal 
actions concerning N. fossalis, see the 2005 final designation of 
critical habitat published in the Federal Register on October 18, 2005 
(70 FR 60658), or the 2009 proposed revised designation of critical 
habitat published in the Federal Register on June 10, 2009 (74 FR 
27588), or contact the Carlsbad Fish and Wildlife Office (see FOR 
FURTHER INFORMATION CONTACT).
    The Center for Biological Diversity filed a complaint in the U.S. 
District Court for the Southern District of California on December 19, 
2007, challenging our designation of critical habitat for Navarretia 
fossalis and Brodiaea filifolia (Center for Biological Diversity v. 
United States Fish and Wildlife Service et al., Case No. 07-CV-2379-W-
NLS). This lawsuit challenged the validity of the information and 
reasoning we used to exclude areas from the 2005 critical habitat 
designation for N. fossalis. We reached a settlement agreement on July 
25, 2008, in which we agreed to reconsider critical habitat designation 
for N. fossalis. The settlement stipulated that we submit a proposed 
revised critical habitat designation for N. fossalis to the Federal 
Register for publication by May 29, 2009, and submit a final revised 
critical habitat designation to the Federal Register for publication by 
May 28, 2010. On June 10, 2009, we published the revised proposed 
critical habitat designation in the Federal Register (74 FR 27588). On 
January 20, 2010, we were granted an extension to submit a final 
revised critical habitat designation to the Federal Register for 
publication by September 30, 2010.
    Section 3 of the Act defines critical habitat as the specific areas 
within the geographical area occupied by a species, at the time it is 
listed in accordance with the Act, on which are found those physical or 
biological features essential to the conservation of the species and 
that may require special management considerations or protection, and 
specific areas outside the geographical area occupied by a species at 
the time it is listed, upon a determination that such areas are 
essential for the conservation of the species. If the proposed rule is 
made final, section 7 of the Act will prohibit destruction or adverse 
modification of critical habitat by any activity funded, authorized, or 
carried out by any Federal agency. Federal agencies proposing actions 
affecting critical habitat must consult with us on the effects of their 
proposed actions, under section 7(a)(2) of the Act.

Draft Economic Analysis

    Section 4(b)(2) of the Act requires that we designate or revise 
critical habitat based upon the best scientific and commercial data 
available, after taking into consideration the economic impact, impact 
on national security, or any other relevant impact of specifying any 
particular area as critical habitat.
    We prepared a DEA (Entrix, Inc. 2010), which identifies and 
analyzes the potential impacts associated with the proposed revised 
designation of critical habitat for Navarretia fossalis that we 
published in the Federal Register on June 10, 2009 (74 FR 27588). The 
DEA looks retrospectively at costs incurred since the October 13, 1998 
(63 FR 54975), listing of N. fossalis as threatened. The DEA quantifies 
the economic impacts of all potential conservation efforts for N. 
fossalis; some of these costs will likely be incurred regardless of 
whether or not we finalize the revised critical habitat rule. The 
economic impact of the proposed revised critical habitat designation is 
analyzed by comparing a ``with critical habitat'' scenario with a 
``without critical habitat'' scenario. The ``without critical habitat'' 
scenario represents the baseline for the analysis, considering 
protections already in place for the species (for example, under the 
Federal listing and other Federal, State, and local regulations). The 
baseline, therefore, represents the costs incurred regardless of 
whether critical habitat is designated. The ``with critical habitat'' 
scenario describes the incremental impacts associated specifically with 
the designation of critical habitat for the species. The incremental 
conservation efforts and associated impacts are those not expected to 
occur absent the critical

[[Page 19577]]

habitat designation for N. fossalis. 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 may 
consider in the final designation of critical habitat relative to areas 
that may be excluded under section 4(b)(2) of the Act. The analysis 
looks retrospectively at baseline impacts incurred since the species 
was listed, and forecasts both baseline and incremental impacts likely 
to occur if we finalize the proposed revised critical habitat.
    The 2010 DEA (made available with the publication of this notice 
and referred to as the DEA throughout this document unless otherwise 
noted) estimates the foreseeable economic impacts of the proposed 
revised critical habitat designation for Navarretia fossalis. The 
economic analysis identifies potential incremental costs as a result of 
the proposed revised critical habitat designation, which are those 
costs attributed to critical habitat over and above those baseline 
costs coextensive with listing. It also discusses the benefits of 
critical habitat designation. These benefits are primarily presented in 
a qualitative manner. The DEA describes economic impacts of N. fossalis 
conservation efforts associated with the following categories of 
activity: (1) Development, (2) conservation lands management, (3) 
transportation, (4) pipeline projects, (5) flood control, (6) 
agriculture, and (7) fire management.
    Baseline economic impacts are those impacts that result from 
listing and other conservation efforts for Navarretia fossalis. 
Conservation efforts related to flood control and development 
activities constitute the majority of total baseline costs 
(approximately 84 percent of post-designation, upper-bound, baseline 
impacts when a 7 percent discount rate is used) in areas of proposed 
revised critical habitat. Impacts to conservation lands management, 
transportation, and pipeline projects compose the remaining 
approximately 16 percent of post-designation, upper-bound, baseline 
impacts when a 7 percent discount rate is used. Total future baseline 
impacts are estimated to be $30.1 to $123.5 million ($2.9 to $11.7 
million annualized) in present value terms using a 7 percent discount 
rate, over the next 20 years (2010-2029) in areas proposed as revised 
critical habitat (Entrix, Inc. 2010, pp. ES-3-ES-4).
    Conservation costs associated with section 7 consultations for 
development, transportation, and flood control projects comprise the 
quantified incremental impacts for the proposed revised critical 
habitat rule. Impacts associated with transportation constituted the 
largest portion of post-designation, upper-bound incremental impacts, 
accounting for almost 47 percent of the forecast incremental impacts 
applying a 7 percent discount rate. Conservation efforts related to 
development and flood control activities constitute the remainder of 
incremental impacts (37 percent and 16 percent, respectively, of post-
designation upper-bound baseline impacts when a 7 percent discount rate 
is used) in areas of proposed revised critical habitat. The DEA 
estimated total potential incremental economic impacts in areas 
proposed as revised critical habitat over the next 20 years (2010-2029) 
to be $846,000 to $1.2 million ($80,000 to $100,000 annualized) in 
present value terms applying a 7 percent discount rate (Entrix, Inc. 
2010, pp. ES-3-ES-4).
    The DEA considers both economic efficiency and distributional 
effects. In the case of habitat conservation, efficiency effects 
generally reflect the ``opportunity costs'' associated with the 
commitment of resources to comply with habitat protection measures 
(such as lost economic opportunities associated with restrictions on 
land use). The DEA 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 DEA measures lost economic efficiency associated with 
residential and commercial development and 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 revised designation might unduly burden a particular 
group or economic sector.

Changes to Proposed Revised Critical Habitat

    In this document we are proposing revisions to Subunits 1A, 1B, 3B, 
5I, 6A, 6B, and 6C, as identified and described in the revised proposed 
rule that published in the Federal Register on June 10, 2009 (74 FR 
27588), and adding a new Subunit 5C. We received comments from the 
public and from one peer reviewer during the open comment period 
indicating that we should reevaluate the proposed boundaries of 
Subunits 1A, 1B, 3B, 5I, 6A, 6B, and 6C and that we should include 
subunit 5C in the proposed critical habitat. The purpose of the 
revisions described below is to better delineate the areas that meet 
the definition of critical habitat for Navarretia fossalis. All areas 
added to the units proposed in the June 10, 2009 (74 FR 27588), 
proposed rule are within the geographic range occupied by the species 
at the time it was listed and contain the features essential for the 
conservation of the species. These areas contain the primary 
constituent elements (PCEs), which are the physical or biological 
features essential to the conservation of a species, and which the 
species' proposed or designated critical habitat is based on, such as 
space for individual and population growth, and for normal behavior; 
food, water, air, light, minerals, or other nutritional or 
physiological requirements; cover or shelter; sites for breeding, 
reproduction, rearing of offspring, germination, or seed dispersal; and 
habitats that are protected from disturbance or are representative of 
the species' historic geographic and ecological distribution.
    The revisions consist of both additions and removals of land that 
we proposed as critical habitat (74 FR 27588). The changes made in 
Subunits 1A, 1B, 3B, 5I, 6A, 6B, and 6C do not alter the description of 
these subunits in the June 10, 2009, proposed rule (74 FR 27588); 
however, we include revised maps with this publication. We briefly 
describe the changes made for each of these subunits below. We did not 
include Subunit 5C in the proposed rule (74 FR 27588, June 10, 2009), 
so this notice includes the full description and map for Subunit 5C 
below. As a result of these revisions, the overall area proposed for 
critical habitat is 7,609 acres (ac) (3,079 hectares (ha)), an increase 
of 737 ac (298 ha) from the 6,872 ac (2,781 ha) that we proposed as 
critical habitat in the June 10, 2009, proposed rule (74 FR 27588). A 
summary of the total acreage of each proposed subunit is presented in 
Table 1.

Subunit 1A: Cruzan Mesa

    We received comments indicating that we did not capture the entire 
watershed area necessary to fill the vernal pools supporting Navarretia 
fossalis in Subunit 1A. We reviewed aerial imagery and topographic maps 
for this area and verified that the subunit needed revision to 
adequately capture areas that meet the definition of critical habitat 
and include the watershed for the ponding areas on Cruzan Mesa (PCE 2). 
The revised subunit consists of 156 ac (63 ha) of private land, an 
increase of 27 ac (11 ha) from what we proposed as critical habitat in 
the June 10, 2009, proposed rule (74 FR 27588).

Subunit 1B: Plum Canyon

    We received information indicating that the placement of our 
proposed critical habitat for Subunit 1B did not capture the vernal 
pool where Navarretia fossalis occurs in the Plum Canyon area. Due to a 
publication error, the incorrect map was published in the June 10, 
2009, proposed rule (74 FR 27588). In reviewing this subunit, we

[[Page 19579]]

became aware of more accurate data describing this area (Glenn Lukos 
Associates 2009, Exhibit 3 (Appendix D-3 of PCR 2009)). As a result of 
our evaluation of this new information, we remapped the boundaries of 
Subunit 1B. Our remapping corrects our publication error and 
incorporates the new information. Subunit 1B contains physical and 
biological features that are essential to the conservation of N. 
fossalis, including ephemeral wetland habitat (PCE 1), intermixed 
wetland and upland habitats that act as the local watershed (PCE 2), 
and the topography and soils that support ponding during winter and 
spring months (PCE 3). The revised subunit consists of 20 ac (8 ha) of 
private land, a decrease of 12 ac (5 ha) from what we proposed in the 
June 10, 2009, proposed rule (74 FR 27588).

Subunit 3B: Carroll Canyon

    We received information indicating that the western portion of 
Subunit 3B had been graded and does not likely contain the physical and 
biological features essential to the conservation of Navarretia 
fossalis. We reviewed aerial imagery and found this information to be 
correct; therefore, we removed 2 ac (1 ha) of land that no longer meets 
the definition of critical habitat for this species. The revised 
subunit consists of 18 ac (7 ha) (16 ac (6 ha) of land owned by the 
City of San Diego and 2 ac (1 ha) of private land), a decrease of 2 ac 
(1 ha) from what we proposed in the June 10, 2009, proposed rule (74 FR 
27588).

Subunit 5C: J26 Vernal Pool Complex

    We received information from the public that we should propose 
Subunit 5C, a subunit that was designated as critical habitat in our 
October 18, 2005, final rule (70 FR 60658), as revised critical habitat 
in this rule. We did not include Subunit 5C in the proposed rule (74 FR 
27588, June 10, 2009) because we did not have data in our GIS database 
indicating this area was occupied by Navarretia fossalis. We 
subsequently reviewed the data in our files on N. fossalis in Subunit 
5C (the J26 vernal pool complex) and found records of N. fossalis 
occupancy (The Environmental Trust 2001, p. 1; 2000, p. 1). Based on 
this new information and because this vernal pool complex is also 
considered one of the best examples of vernal pool habitat on Otay Mesa 
(The Environmental Trust 2002, p. 2), we are proposing Subunit 5C as 
revised critical habitat. We have mapped the boundary of this subunit 
to conform to our current mapping methodology.
    Subunit 5C is located on eastern Otay Mesa in San Diego County, 
California. This subunit is on the far eastern side of Otay Mesa north 
of Alta Road and south of Lower Otay Reservoir. Subunit 5C consists of 
42 ac (17 ha), including 26 ac (11 ha) of State and local government-
owned land and 16 ac (6 ha) private land. This subunit meets our 
criteria for satellite habitat; it supports a stable occurrence of 
Navarretia fossalis and provides potential connectivity between 
occurrences of N. fossalis in Subunits 5G and 5I. Subunit 5C contains 
the physical and biological features that are essential to the 
conservation of N. fossalis, including ephemeral wetland habitat (PCE 
1), intermixed wetland and upland habitats that act as the local 
watershed (PCE 2), and the topography and soils that support ponding 
during winter and spring months (PCE 3). The physical and biological 
features essential to the conservation of the species in this subunit 
may require special management considerations or protection to address 
threats from nonnative plant species, altered hydrology, and human 
disturbance activities (e.g., unauthorized grazing activity) that occur 
in the vernal pool basins and associated watershed. Please see the 
``Special Management Considerations or Protection'' section of the 
proposed rule for a discussion of the threats to N. fossalis habitat 
and potential management considerations (74 FR 27588, June 10, 2009).

Subunit 5I: Eastern Otay Mesa Vernal Pool Complex

    We are not proposing to revise the boundaries of Subunit 5I; 
however, due to a publication error, we are providing the correct map 
for Subunit 5I in this document. For clarification, we reiterate that 
Subunit 5I consists of 221 ac (89 ha) of private land as described in 
the June 10, 2009, proposed rule (74 FR 27588).

Subunit 6A: San Jacinto River

    We received information from the public that we had not included 
some additional areas that meet the definition of critical habitat for 
Navarretia fossalis in Subunit 6A. We reviewed the new information 
provided, including a 2005 map that provided better survey data along 
the San Jacinto River (Helix Environmental, Inc. 2005, map). Based on 
the new information, we included additional areas in this subunit that 
meet the definition of critical habitat for N. fossalis. We expanded 
the critical habitat designation boundary for Subunit 6A in the 
following areas: (1) Around 13th Street to the east of the San Jacinto 
River, (2) east to Dawson Road and north to Ellis Road near Simpson 
Road, (3) around the Case Road vernal pool, and (4) north of the Green 
Valley Parkway. The revised subunit consists of 4,312 ac (1,745 ha) of 
private land, an increase of 762 ac (308 ha) from what we proposed in 
the June 10, 2009, proposed rule (74 FR 27588).

Subunit 6B: Salt Creek Seasonally Flooded Alkali Plain

    A peer reviewer recommended that we revise the boundaries of the 
proposed critical habitat in three areas of Subunit 6B, because we had 
included areas that were disturbed by past activities and no longer 
meet the definition of critical habitat and had not included some areas 
that meet the definition of critical habitat for Navarretia fossalis. 
Following evaluation of this area in greater detail, we agreed with the 
peer reviewer and made changes to this subunit in the central portion 
on the east side, on the north end, and near the Hemet Airport. We are 
no longer proposing an area near the center on the east side that was 
developed and disturbed many years ago, has not supported N. fossalis 
since 1990, and therefore no longer meets the definition of critical 
habitat. Also, we are no longer proposing some land in the northern 
portion of the proposed subunit because it is dry, disturbed, and does 
not meet the definition of critical habitat for N. fossalis. Finally, 
we included vernal pool habitat on the eastern edge of our proposed 
subunit near the Hemet Airport that meets the definition of critical 
habitat for N. fossalis. The revised subunit consists of 943 ac (382 
ha) of private land, a decrease of 111 ac (45 ha) from what we proposed 
in the June 10, 2009, proposed rule (74 FR 27588).

Subunit 6C: Wickerd Road and Scott Road Pools

    We received information that we had not adequately captured the 
physical and biological features essential to the conservation of 
Navarretia fossalis in Subunit 6C. We received new information 
describing the Wickerd Road vernal pool (Roberts 2009, p. 1). We 
reviewed the new information, including the information about the 
vernal pool and newer aerial imagery for this area. As a result, we 
revised the subunit to include the upward sloping area between the 
Wickerd Road vernal pool and Scott Road that meets the definition of 
critical habitat for N. fossalis and contributes to the watershed of 
this vernal pool. The revised subunit consists of 235 ac (95 ha) of 
private land, an increase of 30 ac (12 ha) from what we proposed in the 
June 10, 2009, proposed rule (74 FR 27588).

Additional Areas Currently Considered For Exclusion Under Section 
4(b)(2) of the Act- The Ramona Grasslands Preserve

    In the proposed revised critical habitat designation published on 
June 10, 2009 (74 FR 27588), we identified lands in Subunit 4E as 
meeting the definition of critical habitat for Navarretia fossalis. 
Based on comments submitted during the initial public comment period 
from June 10, 2009, to August 10, 2009, we are also considering for 
exclusion from critical habitat under section 4(b)(2) of the Act the 
portion of Subunit 4E within the Ramona Grasslands Preserve. Of the 135 
ac (55 ha) proposed in Subunit 4E, 51 ac (21 ha) are part of the Ramona 
Grasslands Preserve, which is owned by the Nature Conservancy and San 
Diego County, and managed by San Diego County Department of Parks and 
Recreation. The Ramona Grasslands Preserve is covered by a conservation 
easement and being managed and monitored according to the ``Area 
Specific Management Directives for the Ramona Grasslands Preserve'' 
drafted by San Diego County (2007). The management plan for the Ramona 
Grasslands Preserve provides for the conservation of N. fossalis and 
its habitat through vernal pool management goals, including: managing 
nonnative invasive plant species, maintaining the vernal pool 
hydrology, and managing grazing activities to benefit vernal pool 
habitat (Conservation Biology Institute 2007, pp. 26-27, 31-34). This 
area will be incorporated into the North County Multiple Species 
Conservation Plan (North County MSCP) upon completion of that plan (San 
Diego County 2009).
    As we stated earlier, we request data and comments from the public 
on the DEA, on all aspects of the proposed revised critical habitat 
rule (including the changes to proposed critical habitat in Subunits 
1A, 1B, 3B, 5C, 5I, 6A, 6B, and 6C), and our amended required 
determinations. The final revised rule may differ from the proposed 
revised rule based on new information we receive during the public 
comment periods. In particular, we may exclude an area from critical 
habitat if we determine that the benefits of excluding the area 
outweigh the benefits of including the area as critical habitat, 
provided the exclusion will not result in the extinction of the 
species.

Required Determinations---Amended

    In our proposed rule published in the Federal Register on June 10, 
2009 (74 FR 27588), we indicated that we would defer our determination 
of compliance with several statutes and Executive Orders until the 
information concerning potential economic impacts of the designation 
and potential effects on landowners and stakeholders became available 
in the DEA. We have now made use of the DEA to make these 
determinations.
    In this document, we affirm the information in our June 10, 2009, 
proposed rule (74 FR 27588) concerning Executive Order (E.O.) 12866 
(Regulatory Planning and Review), E.O. 13132 (Federalism), E.O. 12988 
(Civil Justice Reform), the Paperwork Reduction Act, the National 
Environmental Policy Act, and the President's memorandum of April 29, 
1994, ``Government-to-Government Relations with Native American Tribal 
Governments'' (59 FR 22951). However, based on the DEA data, we are 
amending our required determinations concerning the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.), E.O. 13211 (Energy Supply, 
Distribution, or Use), E.O. 12630 (Takings), and the Unfunded Mandates 
Reform Act (2 U.S.C. 1501 et seq.).

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

    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq., as 
amended by the Small Business Regulatory Enforcement Fairness Act 
(SBREFA) of 1996), whenever an agency is required to 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 effect of the rule on small entities (i.e., small 
businesses, small organizations, and small government jurisdictions), 
as described below. However, no regulatory flexibility analysis is 
required if the head of an agency certifies the rule will not have a 
significant economic impact on a substantial number of small entities. 
Based on our DEA of the proposed revised designation, we provide our 
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 receive, we may revise this determination as part 
of a final rulemaking.
    According to the Small Business Administration, small entities 
include small organizations, such as independent nonprofit 
organizations; small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents; and 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 this 
designation as well as 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 proposed revised designation of critical 
habitat for Navarretia fossalis would affect a substantial number of 
small entities, we consider the number of small entities affected 
within particular types of economic activities, such as residential and 
commercial development. In order to determine whether it is appropriate 
for our agency to certify that this rule would not have a significant 
economic impact on a substantial number of small entities, we 
considered each industry or category individually. 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.
    If we finalize this proposed 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 
would be incorporated into the existing consultation process because 
Navarretia fossalis is listed as a threatened species under the Act. In 
the 2010 DEA, we evaluated the potential economic effects on small 
business entities resulting from implementation of conservation actions 
related to the proposed revision to critical habitat for Navarretia 
fossalis. The analysis was based on the estimated incremental impacts 
associated with the proposed rulemaking as described in sections 3 
through 10 of the DEA. The SBREFA analysis evaluated the potential for 
economic impacts related to several categories, including: (1) 
Residential, commercial and industrial

[[Page 19581]]

development; (2) conservation lands management; (3) transportation; (4) 
pipeline projects; (5) flood control; (6) agriculture; and (7) fire 
management (Entrix, Inc. 2010, p. A-1). The DEA found that the only 
category of activity where the designation may impact small businesses 
is residential, commercial, and industrial development (Entrix, Inc. 
2010, pp. A-1-A-4). For residential, commercial, and industrial 
development, the DEA estimated that there will be approximately 38 
development projects in the areas proposed as critical habitat over the 
next 20 years. The total incremental impact to residential, commercial, 
and industrial development was estimated to be between $112,000 and 
$431,000 at a 7 percent discount rate over the next 20 years. On an 
annual basis this affects approximately two development related small 
businesses with a total annual impact ranging from $10,565 to $40,646 
(Entrix, Inc. 2010, pp. A-3-A-4). In a regional context, there are 
approximately 500 small development related businesses in San Diego 
County and 303 in Riverside County. The 38 development related small 
businesses that may be impacted represent approximately 5 percent of 
the total number of development related small businesses in San Diego 
and Riverside Counties. We do not believe that this represents a 
substantial number of development-related small businesses or that an 
annual impact ranging from $10,565 to $40,646 is a significant economic 
impact; therefore, we do not find that the designation of critical 
habitat for N. fossalis will have a significant economic impact on a 
substantial number of small entities.
    In summary, we considered whether the proposed revised designation 
would result in a significant economic impact on a substantial number 
of small entities. For the above reasons and based on currently 
available information, we certify that, if promulgated, the proposed 
revised critical habitat for Navarretia fossalis would not have a 
significant economic impact on a substantial number of small entities. 
Therefore, an initial regulatory flexibility analysis is not required.

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

    On May 18, 2001, the President issued E.O. 13211 on regulations 
that significantly affect energy supply, distribution, and use. 
Executive Order 13211 requires agencies to prepare Statements of Energy 
Effects when undertaking certain actions. The OMB's guidance for 
implementing this Executive Order outlines nine outcomes that may 
constitute ``a significant adverse effect'' when compared to no 
regulatory action. As discussed in Appendix A, the DEA finds that none 
of these criteria are relevant to this analysis. The DEA concludes that 
no incremental impacts on the production, distribution, or use of 
energy are forecast associated specifically with this rulemaking. All 
forecast impacts are expected to occur associated with the listing of 
Navarretia fossalis, regardless of the designation of critical habitat. 
Therefore, designation of 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, the Service 
makes the following findings:
     (a) 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 also 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. ``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.''
    Critical habitat designation 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. Designation of critical habitat may indirectly impact non-
Federal entities that receive Federal funding, assistance, or permits, 
or that otherwise require approval or authorization from a Federal 
agency. However, 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.
     (b) As discussed in the DEA of the proposed revised designation of 
critical habitat for Navarretia fossalis, we do not believe that this 
rule would significantly or uniquely affect small governments because 
it would 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 DEA concludes that incremental 
impacts may occur due to administrative costs of section 7 
consultations for development, transportation, and flood control 
projects activities; however, these are not expected to affect small 
governments. Incremental impacts associated with these activities 
[jsc8]are expected to be borne by the Federal Government, California 
Department of Transportation, California Department of Fish and Game, 
Riverside County, Riverside County Flood Control and Water Conservation 
District, and City of Perris, which are not considered small 
governments. Consequently, we do not believe that the revised critical 
habitat designation would significantly or uniquely affect small 
government entities. As such, a Small Government Agency Plan is not 
required.

Executive Order 12630 -- Takings

     In accordance with E.O. 12630 (``Government Actions and 
Interference with Constitutionally Protected Private Property 
Rights''), we analyzed the potential takings implications of proposing 
revised critical habitat for Navarretia fossalis 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. The

[[Page 19582]]

proposed revised critical habitat for N. fossalis does not pose 
significant takings implications for the above reasons.
