SUPPLEMENTARY INFORMATION:

Extension of Comment Period

On November 2, 2015 (80 FR 67386) we (NMFS) published in the Federal Register a request for public comment on the Proposed Endangered Species Act Recovery Plan for Snake River Fall Chinook Salmon. The public comment period for this action is set to end on January 4, 2016. The comment period is being extended through February 5, 2016, to provide additional opportunity for public comment.

Background

We are responsible for developing and implementing recovery plans for Pacific salmon and steelhead listed under the ESA of 1973, as amended (16 U.S.C. 1531 et seq.). The ESA requires the development of recovery plans for each listed species unless such a plan would not promote its recovery.

We believe it is essential to have local support of recovery plans by those whose activities directly affect the listed species and whose continued commitment and leadership will be needed to implement the necessary recovery actions. We therefore support and participate in collaborative efforts to develop recovery plans that involve state, tribal, and federal entities, local communities, and other stakeholders. For this Proposed Plan for threatened Snake River Fall Chinook Salmon, we worked collaboratively with state, tribal, and federal partners to produce a recovery plan that satisfies the ESA requirements. We have determined that this Proposed ESA Recovery Plan for Snake River Fall Chinook Salmon meets the statutory requirements for a recovery plan and we are proposing to adopt it as the ESA recovery plan for this threatened species. Section 4(f) of the ESA, as amended in 1988, requires that public notice and an opportunity for public review and comment be provided prior to final approval of a recovery plan. This notice solicits comments on this Proposed Plan.

Development of the Proposed Plan

For the purpose of recovery planning for the ESA-listed species of Pacific salmon and steelhead in Idaho, Oregon, and Washington, NMFS designated five geographically based “recovery domains.” The Snake River Fall Chinook Salmon ESU spawning range is in the Interior Columbia domain. For each domain, NMFS appointed a team of scientists, nominated for their geographic and species expertise, to provide a solid scientific foundation for recovery plans. The Interior Columbia Technical Recovery Team included biologists from NMFS, other federal agencies, states, tribes, and academic institutions.

A primary task for the Interior Columbia Technical Recovery Team was to recommend criteria for determining when each component population within an ESU or distinct population segment (DPS) should be considered viable (i.e., when they are have a low risk of extinction over a 100-year period) and when ESUs or DPSs have a risk of extinction consistent with no longer needing the protections of the ESA. All Technical Recovery Teams used the same biological principles for developing their recommendations; these principles are described in the NOAA technical memorandum Viable Salmonid Populations and the Recovery of Evolutionarily Significant Units (McElhany et al., 2000). Viable salmonid populations (VSP) are defined in terms of four parameters: abundance, productivity or growth rate, spatial structure, and diversity.

We also collaborated with state, tribal, and federal biologists and resource managers to provide technical information used to develop the Proposed Plan. In addition, NMFS established a multi-state (Idaho, Oregon, and Washington), tribal, and federal partners' regional forum called the Snake River Coordination Group that addresses the four ESA-listed Snake River salmon and steelhead species. They met twice a year to be briefed and provide technical and policy information to NMFS. We presented regular updates on the status of this Proposed Plan to the Snake River Coordination Group and posted draft chapters on NMFS' West Coast Region Snake River recovery planning Web page. We also made full drafts of the Proposed Plan available for review to the state, tribal, and Federal entities with which we collaborated to develop the plan.

In addition to the Proposed Plan, we developed and incorporated the Module for the Ocean Environment (Fresh et al. 2014) as Appendix D to address Snake River Fall Chinook Salmon recovery needs in the Columbia River estuary, plume, and Pacific Ocean. To address recovery needs related to the Columbia River Hydropower System, we developed and incorporated the Supplemental Recovery Plan Module for Snake River Salmon and Steelhead Mainstem Columbia River Hydropower Projects (NMFS 2014b) as Appendix E of this Proposed Plan. To address recovery needs related to the Lower Columbia River mainstem and estuary, we incorporated the Columbia River Estuary ESA Recovery Plan Module for Salmon and Steelhead (NMFS 2011a) as Appendix F. To address recovery needs for fishery harvest management in the mainstem Snake and Columbia Rivers, Columbia River estuary, and ocean, we developed and incorporated the Snake River Harvest Module (NMFS 2014a) as Appendix G.

The Public Draft Recovery Plan

The Proposed Plan contains biological background and contextual information that includes description of the ESU, the planning area, and the context of the plan's development. It presents relevant information on ESU structure, guidelines for assessing salmonid population and ESU status, and a brief summary of Interior Columbia Technical Recovery Team products on population structure and species status. It also presents NMFS' proposed biological viability criteria and threats criteria for delisting.

As described in Chapter 2 of the Proposed Plan, the historical Snake River fall Chinook salmon ESU consisted of two populations. The population above the Hells Canyon Dam Complex is extirpated, leaving only one extant population—the Lower Mainstem Snake River population. An ESU with a single population would be at greater extinction risk than an ESU with multiple populations. This is a key consideration in the proposed Snake River fall Chinook salmon biological viability criteria, since there is more than one possible scenario for achieving the criteria. The proposed viability criteria include two possible scenarios and a placeholder for developing additional scenarios that would be consistent with delisting. Scenario A focuses on achieving ESA delisting with two populations (i.e., the extant Lower Mainstem Snake River population and a recovered Middle Snake population above the Hells Canyon Complex). Scenario B illustrates a single-population pathway to delisting. The placeholder scenario describes a framework under which additional single-population scenarios could be developed that would involve developing natural production emphasis areas that would have a low percentage of hatchery-origin spawners. NMFS is interested in comments on how such additional scenarios might be developed, potentially for inclusion in the final recovery plan.

The Proposed Plan also describes specific information on the following: current status of Snake River Fall Chinook Salmon; limiting factors and threats throughout the life cycle that have contributed to the species decline; recovery strategies and actions addressing these limiting factors and threats; and a proposed research, monitoring, and evaluation program for adaptive management. For recovery actions, the Proposed Plan includes a table summarizing each proposed action, life stage affected, estimated costs, timing, and potential implementing entities. It also describes how implementation, prioritization of actions, and adaptive management will proceed. The Proposed Plan also summarizes time and costs (Chapter 9) required to implement recovery actions. In some cases, costs of implementing actions could not be determined at this time and NMFS is interested in additional information regarding scale, scope, and costs of these actions. We are also particularly interested in comments on establishing appropriate forums to coordinate implementation of the recovery plan.

Public Comments Solicited

We are soliciting written comments on the Proposed Plan. All substantive comments received by the date specified above will be considered and incorporated, as appropriate, prior to our decision whether to approve the plan. While we invite comments on all aspects of the Proposed Plan, we are particularly interested in comments on developing specific scenarios to address the placeholder recovery scenario, comments on the cost of recovery actions for which we have not yet determined implementation costs, and comments on establishing an appropriate implementation forum for the plan. We will issue a news release announcing the adoption and availability of the final plan. We will post on the NMFS West Coast Region Web site (www.wcr.noaa.gov) a summary of, and responses to, the comments received, along with electronic copies of the final plan and its appendices.
