Fisheries Off West Coast States; West Coast Salmon Fisheries; 
Amendment 14; Essential Fish Habitat Descriptions for Pacific Salmon

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Proposed rule; request for comments.

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

SUMMARY: NMFS proposes regulations to implement Amendment 14 to the 
Pacific Salmon Fishery Management Plan (Salmon FMP) to identify and 
describe essential fish habitat (EFH) for Pacific salmon. The intent of 
this proposed rule is to codify the EFH identifications and 
descriptions for freshwater and marine habitats of Pacific salmon 
managed under the Salmon FMP, including Chinook, coho, and pink salmon. 
This proposed rule complies with an order issued by the U.S. District 
Court of Idaho directing NMFS to codify the EFH identifications and 
descriptions contained in the Salmon FMP. This proposed EFH rule is 
separate and distinct from the December 2004 proposed critical habitat 
rules in which NMFS proposed critical habitat for seven groupings of 
Chinook and coho salmon listed as threatened or endangered species 
under the Endangered Species Act (ESA). Where EFH and critical habitat 
overlap, NMFS will generally merge the results of both consultations 
into one response package to maximize regulatory efficiencies whenever 
possible.

SUPPLEMENTARY INFORMATION: Among other things, the Magnuson-Stevens 
Fishery Conservation and Management Act (Magnuson-Stevens Act) 
authorizes development of Federal Fishery Management Plans (FMPs), and 
Federal regulation of domestic fisheries under those FMPs, within the 
200-mile U.S. Exclusive Economic Zone (EEZ). 16 U.S.C. 1811, 1853. To 
assist the Secretary of Commerce (Secretary) in carrying out specific 
management and conservation duties, the Magnuson-Stevens Act created 
eight regional fishery management councils. Under the Magnuson-Stevens 
Act, an FMP and any amendments are usually originated by one of the 
eight regional fishery management councils, 16 U.S.C. 1852, and must 
then be approved by the Secretary of Commerce. 16 U.S.C. 1854.

Essential Fish Habitat

    The Magnuson-Stevens Act, originally enacted in 1976, has been 
amended several times. In 1996, the Sustainable Fisheries Act (SFA) 
amended the Magnuson-Stevens Act adding provisions aimed at halting 
overfishing and rebuilding overfished fisheries, reducing bycatch, and 
assessing and minimizing the impacts of management measures on fishing 
communities. Congress articulated in its findings that:
    one of the greatest long-term threats to the viability of 
commercial and recreational fisheries is the continuing loss of 
marine, estuarine, and other aquatic habitats. Habitat 
considerations should receive increased attention for the 
conservation and management of fishery resources of the United 
States. 16 U.S.C. 1801(a).
    In making such findings, Congress declared one of the purposes of 
the Magnuson-Stevens Act to be the promotion of ``the protection of 
[EFH] in the review of projects conducted under Federal permits, 
licenses, or other authorities that affect or have the potential to 
affect such habitat.'' 16 U.S.C. 1802(b)(7). To ensure habitat 
considerations receive increased attention for the conservation and 
management of fishery resources, the amended Magnuson-Stevens Act 
required each existing, and any new, FMP to:
    describe and identify essential fish habitat for the fishery 
based on the guidelines established by the Secretary under section 
1855(b)(1)(A) of this title, minimize to the extent practicable 
adverse effects on such habitat caused by fishing, and identify 
other actions to encourage the conservation and enhancement of such 
habitat. 16 U.S.C. 1853(a)(7).
    ``EFH'' is defined in the Magnuson-Stevens Act as ``those waters 
and substrate necessary to fish for spawning, breeding, feeding, or 
growth to maturity.'' 16 U.S.C. 1802(10).
    The EFH regulations (50 CFR 600.815) establish additional guidance 
to the Councils on how to identify and describe EFH. The regulations 
indicate that Councils should:
    obtain information to describe and identify EFH from the best 
available sources, including peer reviewed literature, unpublished 
scientific reports, data files of government resource agencies, 
fisheries landing reports, and other sources of information.
    The regulations identify four classification levels to organize 
available information relevant to EFH identifications and descriptions. 
Level 1 information is limited to species distributional data; level 2 
information includes habitat-related densities; level 3 includes 
growth, reproduction or survival rates within habitats; and level 4 
consists of production rates by habitat. Councils are encouraged to 
identify and describe EFH based on the highest level of detail (i.e., 
level 4). Readers are encouraged to see the EFH regulations (50 CFR 
600.815, subpart J) for a complete description of each of these levels 
as well as guidance on how the Councils should analyze the available 
information. In determinating EFH, the regulations advise the Councils 
to interpret the available information in a ``risk-averse fashion to 
ensure adequate areas are identified as EFH for managed species.'' 50 
CFR 600.815(a)(1)(iv)(A). For Pacific salmon, the Pacific Fishery 
Management Council (Pacific Council) obtained information at all four 
levels

[[Page 19863]]

for certain freshwater areas, and the first three levels of information 
for the estuaries; only the first level of information was available 
for marine areas.

Amendment 14 to the Pacific Salmon Fishery Management Plan

    The Secretary approved the Salmon FMP under the Magnuson-Stevens 
Act, 16 U.S.C. 1801 et seq., in 1978. The Pacific Council has amended 
the Salmon FMP 14 times since 1978. For more information on the FMP 
process, refer to 16 U.S.C. 1651-1654.
    The Pacific Council identified and described EFH for Pacific salmon 
in Amendment 14 to the Salmon FMP and submitted it on June 12, 2000, 
for Secretarial review. After a public comment period, NMFS approved 
Amendment 14 on September 27, 2000. The Pacific salmon EFH descriptions 
and identifications were not codified during the development of 
Amendment 14.
    NMFS issues this proposed rule in response to a U.S. District Court 
of Idaho (Court) order (Case No. CV02-C-EJL, District Court of Idaho) 
directing NMFS to codify the EFH identifications and descriptions 
contained in the Salmon FMP. The Court determined that the EFH 
identifications and descriptions included in the amendment constitute a 
substantive rule under the Administrative Procedure Act (APA). The 
Court remanded, but did not vacate, the EFH identifications and 
descriptions contained in Amendment 14 to NMFS, and ordered NMFS to 
undertake notice and comment rulemaking to codify identified and 
described EFH for the Pacific salmon fishery.
    The intent of this proposed rule is to codify, in compliance with 
the Court's order, the EFH identifications and descriptions for 
freshwater and marine habitats of Pacific salmon managed under the 
Salmon FMP for Chinook (Oncorhynchus tshawytscha), coho (O. kisutch), 
and pink (O. gorbuscha) salmon in Washington, Oregon, Idaho and 
California.
    As new information becomes available, the Pacific Council will 
consider potential modifications to the identifications and 
descriptions of EFH. The Pacific Council is scheduled to review salmon 
EFH, pursuant to the review process schedule set up by both the 
Magnuson-Stevens Act and the EFH regulations at 50 CFR 600.815(a)(10). 
Upon completion of this 5-year review, the Pacific Council and NMFS may 
propose changes to the EFH descriptions depending on the level of new 
information and the effect that information has on the existing EFH 
identifications and descriptions.
    This proposed rule does not contradict or make obsolete the 
information contained in appendix A of Amendment 14 to the Salmon FMP. 
Rather, this proposed rule summarizes key features of appendix A and 
would codify the EFH geographic extent descriptions for Pacific salmon. 
Appendix A contains important background and supplementary information 
on EFH, and can be found on the Council's website at http://www.pcouncil.org/salmon/salfmp/a14.html.

Pacific Council Approach to EFH Identification

    The Pacific Council chose a comprehensive rather than a limiting 
approach in the Amendment 14 identification of salmon EFH for the 
following reasons, all of which made it very difficult to narrowly 
define EFH geographically. In the marine environment, Pacific salmon 
distribution is: (1) extensive; (2) varies seasonally and 
interannually; and (3) has not been extensively sampled in many ocean 
areas. In estuaries and freshwater, there is a high degree of natural 
variability in distribution of salmon species and habitat use (e.g., 
fluctuation in population abundance that can lead to a wider extent of 
habitat being used during high abundance years and a smaller extent of 
habitat being occupied during lower abundance years; varying levels of 
habitat quality; and interannual stream flow variation and water 
quality changes). For these reasons, the Pacific Council was not able 
to designate EFH based on fixed attributes of the streams (e.g., 
channel morphology (channel habitat type), streamflow, water quality, 
riparian condition, and temperature) because there may be areas of 
degraded habitat that may still be used by Pacific salmon and 
considered EFH.
    The Pacific Council chose to adopt an inclusive, watershed-based 
description of EFH using United States Geological Survey (USGS) 
hydrologic units, because it recognizes the species' use of diverse 
habitats, considers the variability of freshwater habitat as affected 
by environmental conditions (droughts, floods, etc.), and reinforces 
important linkages between aquatic and adjacent upslope areas. A more 
detailed background on the Pacific Council's approach can be found in 
appendix A of Amendment 14 to the Salmon FMP.

Consideration of Artificial Barriers

    In identifying the upstream extent of EFH, the Pacific Council 
considered artificial barriers and dams that affect Pacific salmon 
habitat. Numerous hydropower, water storage, and flood control systems 
have been built that either block access to areas historically 
accessible to Pacific salmon or alter the hydrology of downstream 
reaches. The Pacific Council therefore considered whether more than 50 
large impassible barriers in Washington, Idaho, Oregon, and California 
should be designated as the upstream extent of EFH. These barriers are 
identified in Table 1 to part 660, subpart H. Should it become feasible 
for Pacific salmon to have access to or be reintroduced above the 
impassible dams, the FMP requires the Pacific Council to recommend 
identifying and describing the areas above the barriers as Pacific 
salmon EFH. The potential for expansion of EFH under these 
circumstances is addressed at 50 CFR 600.815(a)(1)(iv)(C) and (F).

Pacific Salmon Biology

    The Magnuson-Stevens Act links EFH identifications and descriptions 
to life history stages, and the physiological, biological, and habitat 
parameters on which each life stage depends. To accomplish the task of 
linking these parameters in a meaningful way, the Pacific Council 
established tables and a narrative that present habitat requirements as 
they relate to fish life history stage and physiology. The four life 
history stages are eggs, larvae (alevins), juveniles, and adults. The 
biological needs include diet, substrate type, water quality, and 
others. These tables can be found in appendix A of Amendment 14 (Tables 
A-3, A-4, and A-5).
    A brief overview of Pacific salmon life history and habitat 
requirements is provided below. This information is not intended to be 
a thorough review of Pacific salmon habitat requirements. Rather, it is 
intended to provide a sample of the information that supported the 
Pacific Council's EFH identifications and descriptions. See appendix A 
of Amendment 14 to the Salmon FMP for more detailed information on 
habitat use specific to life stage.
    Chinook, coho, and pink salmon all have similar life history and 
habitat requirements; yet all three species have unique survival and 
reproductive strategies. They are anadromous, and by definition live 
the first part of their lives in freshwater and the adult part of their 
lives in marine waters before returning to spawn in freshwater.
    For spawning and rearing, these salmon require clean, cold, well-
oxygenated water with moderate

[[Page 19864]]

current. Spawning adults need medium to coarse gravel in which to 
deposit eggs. Eggs and alevins need well-oxygenated interstitial spaces 
with continuous water flow. This life stage is susceptible to poor 
water quality, predation, and physical impacts such as flooding or 
excessive siltation, which can smother the eggs.
    At an age that varies among species, juvenile salmon migrate 
downstream towards the ocean. During this migration, the juvenile 
salmon require high water quality and protection from predation. 
Estuaries provide a mixing zone of saline and freshwater in which the 
young salmon can adapt to marine waters.
    Pacific salmon use large portions of the north Pacific during ocean 
migration, although patterns vary between species and even between 
different populations of the same species. It is clear that ocean 
migration can be extensive. During the ocean phase, salmon are 
susceptible to predation, fishing mortality, and lack of food 
resources. The Pacific Council and NMFS considered excluding large 
portions of the EEZ from EFH designation. However, the best scientific 
information available was insufficient to support refinement. They 
chose, therefore, to identify and describe the entire EEZ as EFH for 
Pacific salmon. The Pacific Council adopted relatively broad EFH 
descriptions because of the wide ranging life history strategy, the 
number of species involved, and the limited information on marine 
distribution.

EFH for Chinook, Coho, and Pink Salmon

    Table 1 to part 660, subpart H lists those hydrologic units which 
are identified as EFH for Chinook, coho, and pink salmon. Table 1 also 
includes, where appropriate, the names of impassible barriers that 
represent the upstream extent of Pacific salmon distribution.
    To assist Federal agencies and the public, the following three 
figures depict those 4th field USGS Hydrologic Unit Codes (HUCs) that 
contain EFH for Pacific salmon. Figure 1 shows HUCs and marine waters 
that contain EFH for Chinook salmon in Washington, Oregon, California, 
and Idaho. Figure 2 shows HUCs and marine waters that contain EFH for 
coho salmon in Washington, Oregon, California, and Idaho. Figure 3 
shows HUCs and marine waters that contain EFH for pink salmon in 
Washington.

EFH in Alaskan Marine Waters

    In identifying and describing EFH for Pacific salmon in Amendment 
14, the Pacific Council included those areas that have been identified 
and described as marine EFH for Pacific salmon by the North Pacific 
Fishery Management Council (North Pacific Council). While the task of 
identifying and describing EFH in Alaskan waters is the responsibility 
of the North Pacific Council, the Pacific Council chose to include the 
reference to Alaskan EFH in Amendment 14 to the Salmon FMP in order to 
emphasize the relationship within the Pacific Coast ecosystem used by 
Pacific salmon during their adult migrations. This proposed rule, 
however, only codifies EFH for Pacific salmon that is within the 
jurisdiction of the Pacific Council, and does not codify EFH identified 
and described by the North Pacific Council for Pacific salmon

[[Page 19868]]

that is found in Alaskan waters under the North Pacific Council's 
jurisdiction.

Effects of Identifying and Describing EFH

    Once EFH is identified and described, the Magnuson-Stevens Act 
requires that each FMP minimize to the extent practicable adverse 
effects to EFH. Adverse effects are broadly divided into effects from 
fishing and nonfishing activities. For impacts to EFH caused by fishing 
activities, each FMP must consider measures to minimize adverse effects 
on EFH, including EFH identified and described under other Federal 
FMPs. These measures may include equipment restrictions, time/area 
closures, or harvest limits.
    In addition, the Magnuson-Stevens Act requires any Federal agency 
that determines that its action may adversely affect EFH to consult 
with NMFS. Section 305(b)(2) of the Magnuson-Stevens Act defines a 
Federal action as ``any action authorized, funded, or undertaken, or 
proposed to be authorized, funded, or undertaken, by such agency that 
may adversely affect any essential fish habitat identified under this 
Act.'' The consultation process is fully described in the EFH 
regulations at 50 CFR 600.920. In order for NMFS to conduct this 
consultation the Federal action agency provides an EFH assessment 
commensurate with the complexity and magnitude of the potential adverse 
effects of the action.
    After receiving a request for consultation and accompanying EFH 
assessment, NMFS must develop Conservation Recommendations for those 
actions that would adversely affect EFH, aimed at the need to avoid, 
minimize, mitigate, or offset adverse effects of the proposed action. 
NMFS must also provide Conservation Recommendations for those Federal 
and state actions that would adversely affect EFH in situations where 
consultation has not been requested. Upon receiving the recommended 
conservation measures, the Federal action agency must provide a 
detailed written response within 30 days, indicating the proposed 
measures to avoid or minimize adverse impacts on EFH. If the response 
is inconsistent with NMFS Conservation Recommendations, the Federal 
agency must explain its reasons for not following the recommendations, 
including the scientific justification for any disagreements with NMFS 
over the anticipated effects of the action and the measures needed to 
avoid, minimize, mitigate, or offset such effects.

Distinction Between EFH and Critical Habitat

    EFH responsibilities under the Magnuson-Stevens Act should not be 
confused with the mandate to designate critical habitat under the ESA. 
Congress enacted these two statutes with very different purposes in 
mind. One of the purposes of the Magnuson-Stevens Act is to promote 
domestic commercial and recreational fisheries. In amending the 
Magnuson-Stevens Act, Congress found that:
    [o]ne of the greatest long-term threats to the viability of 
commercial and recreational fisheries is the continuing loss of 
marine, estuarine, and other aquatic habitats. Habitat 
considerations should receive increased attention for the 
conservation and management of fishery resources of the United 
States. 16 U.S.C 1801(a)(9).
    Under the Magnuson-Stevens Act, Congress established the mandate to 
identify and describe EFH in order to support the habitat needs of 
federally managed fish stocks to aid in ensuring long-term sustainable 
fisheries.
    The definition of EFH within the Magnuson-Stevens Act, as well as 
the EFH implementing regulations (EFH Final Rule), establishes a basis 
for broader geographic areas to be identified and described as EFH, 
compared with those areas designated as critical habitat. The Magnuson-
Stevens Act defines EFH as ``those areas necessary to fish for 
spawning, breeding, feeding, or growth to maturity.'' 16 U.S.C. 
1802(10). The EFH Final Rule provides a mechanism for aiding the 
fishery management councils in determining the extent of EFH for the 
managed species. While the EFH Final Rule emphasizes that EFH should be 
distinguished from all habitats potentially used by the managed 
species, it also states that ``[a]reas described as EFH will normally 
be greater than or equal to aquatic areas that have been identified as 
'critical habitat' for any managed species listed as threatened or 
endangered under the [ESA].'' 50 CFR 600.815(a)(1)(iv)(D). In addition, 
the EFH Final Rule provides the opportunity to increase the size of the 
area identified as EFH to include historic and/or degraded habitats 
where habitat loss may be contributing to reduced yield of the managed 
species.
    In contrast, the ESA was enacted ``to provide a means whereby the 
ecosystems upon which endangered species and threatened species depend 
may be conserved'' and ``to provide a program for the conservation of 
such endangered species and threatened species.'' 16 U.S.C. 1531(b). 
The ESA specifically articulates that:
    the term 'critical habitat' for a threatened or endangered 
species means -
    1. the specific areas within the geographic area occupied by the 
species at the time it is listed . . . on which are found those 
physical or biological features essential to the conservation of the 
species and . . . which may require special management 
considerations and protections; and
    2. specific areas outside the geographic area occupied by the 
species at the time it is listed . . . upon a determination by the 
Secretary that such areas are essential for the conservation of the 
species. 16 U.S.C. 1532(5)(A).
    The definition of critical habitat in the ESA also indicates that 
``except in those situations determined by the Secretary, critical 
habitat shall not include the entire geographic area which can be 
occupied by the threatened or endangered species.'' 16 U.S.C. 
1532(5)(C). While the ESA's implementing regulations regarding critical 
habitat set forth procedures for designating areas outside the current 
area occupied by the species, unlike EFH in the Magnuson-Stevens Act, 
the ESA regulations also allow the agency to exclude certain areas from 
critical habitat, or not designate at all, in certain situations.
    When the geographic locations of EFH and critical habitat overlap, 
the individual consultation requirements under the ESA and the 
Magnuson-Stevens Act both apply. If a Federal agency determines that 
its action may adversely affect EFH and may affect critical habitat, it 
must consult with NMFS under the ESA and Magnuson-Stevens Act. In these 
circumstances, NMFS will generally merge the consultations into one 
response package, whenever possible, to maximize efficiency.

Classification

    This proposed rule is published under the authority of the 
Magnuson-Stevens Act, 16 U.S.C. 1801 et seq.
    The NMFS Northwest Region completed an ESA section 7 consultation 
on November 18, 1999, on the effects of Amendment 14 on listed salmon 
evolutionarily significant units. Amendment 14 does not by itself 
authorize any fishing or other activity that would result in adverse 
effects to listed fish or designated critical habitat. Based on this 
and other considerations, NMFS concluded that Amendment 14 and its 
implementing regulations are not likely to adversely affect listed 
salmon or their critical habitat. This proposed rule is consistent with 
the determination in Amendment 14 that the action does not jeopardize 
the continued existence of ESA listed salmon.

[[Page 19869]]

    The Chief Counsel for Regulation of the Department of Commerce 
certified to the Chief Counsel for Advocacy of the Small Business 
Administration that this proposed rule, if adopted, would not have a 
significant economic impact on a substantial number of small entities, 
as follows:
    The objective of this rule is to codify essential fish habitat 
(EFH) descriptions and identifications that were previously approved 
by the Secretary of Commerce (Secretary)for Amendment 14 to the 
Pacific Salmon Fishery Management Plan. EFH descriptions and 
identifications are required under the Magnuson Fisheries 
Conservation and Management Act (16 U.S.C. 1802(b)(7). All vessels 
harvesting salmon from this fishery are considered small under the 
Small Business Act approved definition of a small fish harvester 
(average gross receipts not in excess of $4.0 million). Therefore, 
there can be no disproportionate impacts between small and large 
vessels. Furthermore, there are no disproportionate impacts based on 
homeport, gear type, or vessel size from the promulgation of this 
proposed rule. In 2004, there were 3,008 permits issued for this 
fishery, with a total exvessel value of $28,961,275. Of the 3,008 
permits, only 910 actually landed salmon. There were 1508 vessel 
permits issued in California, 738 of which landed salmon, for an 
exvessel value of $17,883,216. There were 1,181 vessel permits 
issued in Oregon, 595 of which landed salmon, for an exvessel value 
of $9,893,065. There were 160 vessel permits issued in Washington, 
86 of which landed salmon, for an exvessel value of $1,184,994. This 
rule would not result in any immediate impacts on revenues or costs 
for the small entities participating in the Pacific salmon fishery 
because it does not contain any new management measures that would 
have specific economic impact on the fishery. However, future 
rulemakings that are promulgated by NMFS on behalf of the Secretary 
may be based in part on the identification and description of the 
EFH and such actions would likely have specific measurable impacts 
on the small entities participating in the fishery.
    As a result, an initial regulatory flexibility analysis is not 
required and none has been prepared. NMFS will conduct the appropriate 
analyses for any subsequent rulemakings stemming from this proposed 
rule.
    This proposed rule is not significant for the purposes of Executive 
Order 12866 (Supplemental Regulatory Impact Review to Amendment 14 to 
the Pacific Salmon Fishery Management Plan was prepared, see 
ADDRESSES).

\1.\ To clearly identify watersheds that contain EFH, NMFS uses fourth field hydrologic unit codes (HUCs)
  developed by the U.S. Geological Survey (USGS) (defined in the Department of the Interior, USGS publication;
  Hydrologic Unit Maps, Water Supply Paper 2294, 1987). The geographic extent of HUCs range from first field
  (largest geographic extent) to sixth field (smallest geographic extent). Fourth field HUCs divide the
  landscape into distinct geographic areas that are identified by eight numbers unique to that hydrologic unit.
