Opinion

SIERRA SNOWMOBILE No. 2:21-cv-01913-DJC-SCR FOUNDATION, et al.,

Plaintiffs, ORDER v. UNITED STATES FOREST SERVICE, et al., Defendants, WILDEARTH GUARDIANS, et al., Intervenor- Defendants. This case concerns environmental protection policies, including plans that reduced the acreage open to over-snow vehicles ("OSVs"), in the Stanislaus National Forest. Plaintiffs challenge the underlying analysis and actions behind the federal government’s issuance of the Stanislaus National Forest Over-Snow Vehicle Use Designation Record of Decision ("the Decision"), which significantly reduced the acreage open to cross-country motorized OSV use from that previously and historically available to recreationists in the Forest. Intervenor Defendants challenge some elements of Defendants' decision making, while also supporting other elements of Defendants' actions. The Court finds that Defendants complied with the relevant environmental statutes in issuing the Decision and rejects both Plaintiffs' and Intervenor Defendants' claims. The Stanislaus National Forest encompasses 898,099 acres on the western slope of the Sierra Nevada mountain range ranging in elevation from 1,500 to over 11,000 feet above sea level. (ECF No. 1, Compl., ¶ 34.) Almost 215,000 acres within the Stanislaus National Forest are designated Wilderness Areas under the Wilderness Act of 1964, 16 U.S.C. §§ 1131, et seq., and are closed to all motorized travel. (Id.) The Stanislaus National Forest also includes 100,299 acres of Near Natural management areas and 23,107 acres of Proposed Wilderness management areas, both of are designated as nonmotorized spaces. (Id.) Although the Stanislaus Forest Plan provides for Near Natural and Proposed Wilderness areas to be managed as semi-primitive nonmotorized, they were never formally closed to OSV use and have been historically used by OSV riders. (Id.) The Stanislaus National Forest is a destination for a variety of winter recreation activities, including backcountry snowmobiling. (Id. ¶ 36.) Prior to the Decision, the Forest Service permitted cross-country OSV use in the Stanislaus National Forest wherever there was adequate snowfall in areas that allowed for motorized use and in some Near Natural and Proposed Wilderness areas. (Id.) This included areas below 5,000 feet in elevation. (Id.) OSV usage can cause damage to the natural environment. The vehicles compact, rut, and erode soil, particularly in wet meadow areas or at the beginning and end of the winter season when snow levels are lower. AR 000404; AR 003344–45; AR 0003763. Snow compaction from OSV usage can influence local hydrology by delaying snowmelt and run off. AR 003345; AR 003351. OSVs can also damage vegetation under the snow if there is not adequate snow cover, and exhaust emissions or leaked fuels can infiltrate soils or local bodies of water, degrading those resources and affecting the biodiversity that depends on them. AR 003345–46; AR 003351; AR 001675–76. Local wildlife can also be directly impacted by OSV use. Animals may flee when they detect the presence of an OSV, causing them to exert energy (which may be significant for predatory species). AR 000525; AR 004068. Some wildlife avoid areas where OSVs are typically present all together, reducing those species' winter home range and potentially displacing them from preferred habitat for feeding, sheltering, or reproducing. AR 000525; AR 004067. Relatedly, OSVs cause noise and visual disturbances that affect animals, and the compacted snow trails they leave behind can allow predators such as coyotes or bobcats to enter into new territories where their prey species are sheltered. AR 000525–26; AR 004067–69. The vehicles can also suffocate animals beneath the snow or otherwise destroy the habitat of wildlife that inhabit the subnivean space between the snow and the ground. AR 000525; AR 004068. The Stanislaus Forest Plan Direction, implemented by the United States Forest Service, requires a minimum of twelve inches of snow depth for cross-country OSV use but does not specify a minimum snow depth for OSV travel on existing trails. (ECF No. 1 ¶ 38.) Conditions on existing OSV trails vary considerably throughout the Stanislaus National Forest in both the level of snow compaction and the underlying ground conditions, fluctuating to be greater than or less than the twelve-inch minimum snow depth. (Id.) Recognizing the “need to provide a manageable, designated OSV system of trails and areas within the Stanislaus National Forest that is consistent with and achieves the purposes of the Forest Service Travel Management Rule,” the Forest Service issued a Notice of Intent to Prepare an Environmental Impact Statement ("EIS") for a proposal to designate OSV use on roads, trails, and areas and identify trails for grooming within the Stanislaus National Forest. (Id. ¶ 39; 80 Fed. Reg. 36760 (June 26, 2015).) During the 45-day scoping period required under the National Environmental Policy Act (“NEPA”) to gather internal and external input, the Forest Service received over 100 responses regarding its proposal to designate areas and trails in the Stanislaus National Forest for OSV use. (ECF No. 1 ¶ 39.) In August 2018, the Forest Service released the Draft Environmental Impact Statement (“DEIS”) for the Stanislaus National Forest OSV Use Designation project (“Project”). (Id. ¶ 40.) The DEIS analyzed five alternatives to meet the project purpose of providing “for a system of NFS ["National Forest System"] roads, NFS trails, and areas on NFS lands that are designated for over-snow vehicle use where snowfall is adequate for that use to occur.” (Id.) All the alternatives imposed a minimum snow- depth requirement of at least twelve inches for both cross-country and trail OSV use. (Id.) Alternative 1 was the proposed action in the scoping notice with minor modifications. AR 001404, 001407–09. Alternative 2 was the “No-Action Alternative,” in which there would be no change to the way the Forest Service currently manages public OSV use on the Forest. AR 001409. Alternative 3 emphasized opportunities for non-motorized winter recreation. AR 001410. Alternative 4 emphasized motorized use. AR 001411. Alternative 5 was designated as the preferred alternative, which emphasized protections for wildlife and natural resources as well as recreation opportunities for motorized and non-motorized vehicle users. AR 001411. The Forest Service issued the Final Environmental Impact Statement (“FEIS”) and draft Record of Decision (“Draft ROD”) in March 2019. (ECF No. 1 ¶ 47.) All the alternatives assessed in the FEIS assumed that there was no land below 5,000-feet elevation available for OSV use. (Id. ¶ 49.) Forest Supervisor Jason Kuiken signed the final Record of Decision (“Final ROD”) in July 2021. (Id. ¶ 56.) The Final ROD adopted many aspects of Alterative 5, including the Minimum Snow Depth Requirements, Seasons of Use Designations, Temporary Witner Stream Crossing, OSV-use trail designations (both non-groomed and those available for grooming), and the OSV-use designations within the Mi-Wok, North Highway 4, and Spicer OSV-use areas. (Id.) The Final ROD also includes OSV-use designations in the Alpine, Alpine East, Eagle, Highway 108, and Highway 108 East OSV-use areas which differ from Alternative 5. (Id.) Plaintiffs are the Sierra Snowmobile Foundation, BlueRibbon Coalition, Inc., American Council of Snowmobile Associations, Inc., Jeff Wittman, Mary Krupka, and Jeff Watts, a collection of individuals and organizations whose members use OSVs to access Stanislaus National Forest. (ECF No. 40 ¶¶ 3, 9–12.) Federal Defendant is the United States Forest Service. (ECF No. 42 at 1.) Forest Supervisor for the Stanislaus National Forest Jason Kuiken is also a named Defendant and is sued in his official capacity. (Id.) Intervenor Defendants are environmental organizations WildEa
