Notice of availability.


Pursuant to the National Environmental Policy Act of 1969 (NEPA), 42 U.S.C. 4332(2)(C), and the Council on Environmental Quality Regulations (40 CFR part 1500-1508), the National Park Service (NPS) has prepared a Draft Environmental Impact Statement (DEIS) for the proposed Merced Wild and Scenic River Comprehensive Management Plan (Merced River Plan). The Merced River Plan will fulfill the requirements of the Wild and Scenic Rivers Act, 16 U.S.C. 1271-1287, and will provide long-term protection of river values and a user capacity management program for 81 miles of the Merced River that flow through Yosemite National Park and the El Portal Administrative Site.

Consistent with the Wild and Scenic Rivers Act (WSRA), the purposes of the Merced River Plan/DEIS are to protect the Merced River's free-flowing conditions, and to: (1) Review, and if necessary revise, the river corridor boundaries and segment classifications, and provide a process for protection of the river's free-flowing condition in keeping with the WSRA; (2) Refine descriptions of the river's outstandingly remarkable values (ORVs), which are the unique, rare, or exemplary in a regional or national context, and the river-related/river-dependent characteristics that make the river eligible for inclusion in the national wild and scenic rivers system; (3) Identify management objectives for the river, and specific management measures that will be implemented to achieve protection and enhancement of river values; (4) Establish a user capacity program that addresses the kinds and amounts of public use that the river corridor can sustain while protecting and enhancing the river's ORVs; (5) Commit to a program of ongoing studies and monitoring to ensure that the ORVs are protected and enhanced over the life of the plan.

The Merced River Plan/DEIS evaluates the potential adverse and beneficial environmental consequences of implementing a range of five action Start Printed Page 5493alternatives, including a no action alternative in accordance with NEPA; and for the potential to cause adverse effects to historic properties in accordance with Section 106 of the National Historic Preservation Act. Both the agency preferred and environmentally preferred alternatives are identified. Actions called for in the 1980 Yosemite General Management Plan (GMP) addressing management within the Merced Wild and Scenic River corridor would be amended and are outlined in the Merced River Plan/DEIS.


The NPS will be accepting public comments on the Merced River Plan/DEIS for 90 days. All comments must be transmitted or postmarked no later than 90 days from the date of publication of the U.S. Environmental Protection Agency's notice of filing for this Draft EIS in the Federal Register.

Development of Proposal and Alternatives: On April 11, 2007, the NPS published a Notice of Intent to prepare an EIS in the Federal Register. This initial scoping period included three public meetings and resulted in 191 responses. Public scoping was reopened with a Federal Register notice on June 30, 2009, and through multiple public notices in newspapers throughout northern California and the Yosemite region. The second scoping period was extended until February 4, 2010 and resulted in 576 responses. Also throughout this period, e-newsletters were sent to 5,700 recipients and postcards to 25,000 Yosemite campers.

The Merced River Plan/DEIS has been developed through consultation with traditionally associated American Indian tribes, the State Historic Preservation Officer, and other federal and state agencies. Gateway communities, organizations, and interested members of the public have provided more than 1,460 pieces of correspondence (including letters, faxes, emails, comment forms, and public meeting flip-chart notes). The NPS has conducted more than 40 public meetings, presentations, workshops, field visits, and open houses in support of the EIS process. Two preliminary alternatives concept workbooks were prepared and distributed for public review and comment prior to completion of the Merced River Plan/DEIS.

Based on a thorough examination of the river's baseline conditions at the time of designation (1986), a multi-faceted approach to river management and stewardship is proposed. To address the WSRA mandate to protect and enhance river values, many of the plan's actions would be common to all the action alternatives, including: (1) All WSRA management elements (boundaries, classifications, § 7 determination process); (2) actions to protect and enhance river values (e.g., ecological restoration components); (3) removal and/or relocation of numerous facilities and services; (4) actions to improve traffic circulation and reduce congestion; (5) implementation of a monitoring program that sets thresholds for when management actions must be taken to protect river values; and (6) numeric limits on use through a user capacity management program.

In keeping with the expressed purpose and need, the DEIS identifies and evaluates five action alternatives for management of the river corridor, and a No-Action alternative. The action alternatives vary primarily in the degree of restoration and the amount of visitor use that could be accommodated by the commensurate level of facilities and services necessary to protect river values under each scenario. The interdisciplinary and public involvement effort provided varying perspectives and experiences that were considered during the alternative development process.

Alternative 1 (No-Action; baseline conditions) would continue current management and trends, including ongoing localized impacts associated with impacts to free flowing condition of the river and connectivity of meadows, permanent facilities in the Merced River floodplain, and pedestrian-vehicle conflicts at major intersections. In 2011, the peak daily visitation recorded for East Yosemite Valley was 20,900 people over a 24-hour period. Under the existing GMP, East Yosemite Valley visitation would be approximately 18,241 people.

Actions Common to Alternatives 2-6: All five action alternatives would protect and enhance river values by improving conditions that threaten sensitive meadows, archeological resources, and scenic vistas, and would differ primarily in the kinds of visitor opportunities available at Yosemite Valley and the Merced Lake High Sierra Camp. Restoration actions common to alternatives 2-6 include the removal of revetments, abandoned infrastructure, informal trails, and encroaching conifers in meadows; restoring riparian areas and meadow hydrology; regulating river access; and cultural resource protection and scenic resource protection. All alternatives would accommodate traditional cultural practices by American Indian tribes and groups. The action alternatives included in the Merced River Plan more closely align capacity with visitation to improve the visitor experience and allow for more extensive resource protection.

Alternative 2: Self-Reliant Visitor Experiences and Extensive Floodplain Restoration would include major restoration within the 100-year floodplain, significant reduction in facilities and services, and significantly lower visitor use than today. Given the conditions in this Alternative, visitation to East Yosemite Valley would be approximately 13,900 people per day over a 24-hour period.

Alternative 3: Dispersed Visitor Experiences and Extensive Riverbank Restoration would include significant restoration within 150 feet of the river, marked reduction in visitor facilities and services, and significantly lower visitor use than today. Given the conditions in this Alternative, East Yosemite Valley visitation would be approximately 13,200 people per day over a 24-hour period.

Alternative 4: Resource-based Visitor Experiences and Targeted Riverbank Restoration would include targeted restoration within 150 feet of the river, reduced commercial services with a significant increase over current camping opportunities, and slightly lower visitor use than today. Given the conditions in this Alternative, East Yosemite Valley visitation would be approximately 17,000 people per day over a 24-hour period.

Alternative 5 (agency-preferred): Enhanced Visitor Experiences and Essential Riverbank Restoration would include essential restoration within 100 feet of the river, reduced commercial services with moderate increases to current camping opportunities, and approximately the same level of visitor use as today. Given the conditions in this Alternative, East Yosemite Valley visitation would be approximately 19,900 people per day over a 24-hour period. This preferred course of action is also identified as the “environmentally preferred” alternative.

Alternative 6: Diversified Visitor Experiences and Selective Riverbank Restoration would include limited restoration within 100 feet of the river, expanded facilities and services with the largest increase over current camping opportunities, and some growth in visitor use over time. Given the conditions in this Alternative, East Yosemite Valley visitation would be allowed to increase to approximately Start Printed Page 549421,800 people per day over a 24-hour period.
