Winter Use Plans, Final Environmental Impact Statement, Record of
Decision Amendment-Sylvan Pass Management, Yellowstone and Grand Teton
National Parks and the John D. Rockefeller, Jr. Memorial Parkway, Wyoming

AGENCY: National Park Service, Department of the Interior.
ACTION: Notice of Availability of a Record of Decision Amendment--
Sylvan Pass Management on the Final Environmental Impact Statement for
the Winter Use Plans, Final Environmental Impact Statement, Yellowstone
and Grand Teton National Parks and the John D. Rockefeller, Jr.
Memorial Parkway.

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

SUMMARY: Pursuant to the National Environmental Policy Act of 1969, 42
U.S.C. 4332(2)(C), the National Park Service announces the availability
of the Record of Decision Amendment--Sylvan Pass Management for the
Winter Use Plans, Final Environmental Impact Statement, Yellowstone and
Grand Teton National Parks and the John D. Rockefeller, Jr. Memorial
Parkway, Wyoming. On July 16, 2008, the Director, Intermountain Region,
approved the Record of Decision Amendment--Sylvan Pass Management for
the project.
    On November 20, 2007, a Record of Decision was signed on the Winter
Use Plans/Final Environmental Impact Statement for Yellowstone and
Grand Teton National Parks and the John D. Rockefeller, Jr. Memorial
Parkway. The November 20, 2007, Record of Decision (on page 6) addressed
management of Sylvan Pass in Yellowstone National Park, stating:

    ``This decision addresses Sylvan Pass in Yellowstone. For the
winter season of 2007-2008 the pass will be managed continuing the
combined program outlined in the 2004 Temporary Plan. After the
winter of 2007-2008, in order to maximize risk reduction, the pass
would be open and managed using full avalanche forecasting (as
defined in the Sylvan Pass Operational Risk Management Assessment).
When full forecasting indicates the pass is safe, the pass would be
open to oversnow travel (both motorized and non-motorized access).
    ``The National Park Service will, in good faith, work
cooperatively with the State of Wyoming, Park County, Wyoming and
the town of Cody to determine how to provide continued snowmobile
and snowcoach motorized oversnow access to Yellowstone National Park
through the East Gate via Sylvan Pass in the winter use seasons
beyond 2007-2008.
    ``The National Park Service will meet with representatives of
the State of Wyoming, Park County, Wyoming and the town of Cody to
further explore reasonable avalanche and access mitigation safety
measures and costs. In order to provide adequate time to amend this
Record of Decision reflecting a potential consensus of the parties
and to promulgate a new regulation reflecting the amended decision
for the 2008-2009 winter use season and beyond, consensus should be
reached by June 1, 2008.''

    Since the Record of Decision, the NPS has met with representatives
of the City of Cody, Wyoming, Park County, Wyoming, the State of
Wyoming, and Wyoming state elected officials (collectively known as the
Sylvan Pass Study Group) and explored reasonable avalanche and access
mitigation safety measures and costs.
    The outcome of the meetings was that the Sylvan Pass Study Group
recommended to the Intermountain Regional Director of the National Park
Service that the November 2007 Record of Decision on Winter Use in
Yellowstone National Park be amended to keep Sylvan Pass open in future
winter use seasons to motorized and non-motorized oversnow travel for a
limited core season, between December 22 and March 1. The group
recommended continued use of a combination of avalanche mitigation
techniques, including forecasting and helicopter and howitzer dispensed
explosives.
    This recommendation was taken into account in preparing the Record
of Decision Amendment--Sylvan Pass Management (Amendment). The
Amendment only addresses Sylvan Pass in Yellowstone National Park.
Unless specifically modified by the Amendment, all other elements of
the November 20, 2007, Record of Decision remain in place.
    The Amendment is primarily based upon alternative 5 in the Final
Environmental Impact Statement (alternative 5 calls for the same
overall number of snowmobiles in Yellowstone as the November 20, 2007,
decision, and for Sylvan Pass to be kept open).
    The amended decision is that Sylvan Pass will be open for oversnow
travel (both motorized and non-motorized) for a limited core season,
from December 22 through March 1 each winter, subject to weather-
related constraints and NPS fiscal, staff, infrastructural, equipment,
and other safety-related capacities. A combination of avalanche
mitigation techniques may be used, including forecasting and helicopter
and howitzer dispensed explosives. The results of previous safety
evaluations of Sylvan Pass by the Occupational Safety and Health
Administration and an Operational Risk Management

[[Page 50054]]

Assessment will be reviewed and updated, and the NPS will evaluate
additional avalanche mitigation techniques and risk assessment tools in
order to further improve safety and visitor access.
    From March 2 to March 15, the NPS will maintain the road segment
from the East Entrance to a point approximately four miles west of the
entrance station to provide for opportunities for cross-country skiing
and snowshoeing. Limited snowmobile and snowcoach use will be allowed
in order to provide drop-offs for such purposes.
    This course of action and seven alternatives were analyzed in the
Draft and Final Environmental Impact Statements. The full range of
foreseeable environmental consequences was assessed, and appropriate
mitigation measures were identified.
    The Amendment includes a statement of the decision made, synopses
of other alternatives considered, the basis for the decision, a
description of the environmentally preferred alternative, a finding on
impairment of park resources and values, and an overview of the public
and agency involvement in reaching this Record of Decision Amendment.
    On December 13, 2007, a final regulation was published in the
Federal Register (72 FR 70781), which implemented certain provisions of
the November 20, 2007 Record of Decision. The National Park Service has
reviewed the regulation (36 CFR 7.13) and determined that promulgating
a new regulation to implement this Amendment is not necessary.
