- Decision Memo for the Tenmile and Priest Pass Restoration Project
U.S. Forest Service, Helena National Forest
Helena Ranger District
Lewis and Clark County, Montana
DecisionI have decided to implement the Tenmile and Priest Pass Restoration Project as oringinally proposed.This decision will decommission and/or close unauthorized routes including related vehicle disturbancearound dispersed campsites. Project activities will occure from Rimini downstream to the forestboundary and the area along Sweeney Creek from the forest boundary to Priest Pass. The unauthorizedroutes in this decision were identified as redundant or have resulted in ongoing resource damage, andwill be closed and reclaimed. Decommissioning activities will include recontouring, ripping, seeding,and slashing as well as the placement of large woody debris and boulders, and/or construction of jack-leg fence to prevent motorized access. Some unathorized routes associated with dispersed campsites thatare encroaching on sensitive areas will not be decommissioned, but will have boulders installed todiscourage site expansion into the sensitive areas.
A total of approximately 9 miles of user-created routes will be decommissioned and an additional 1.5miles will be closed with barriers to motorized vehicles (see Attachemnt A for maps and routes andtreatment details).
This project will not include any new travel management decisions. All routes proposed fordecommnissioning are unauthorized user-created routes and are not included on the Helena NationalForest Visitor Map as designated system routes. Order Number H-01-05 signed June 27, 2001 prohibitsoff-route motorized use on the Helena National Forest.
Additionally, resource protection measures as listed below are incorporated into this decision forimplementation.
• Fisheries: Instream activities will be compliant with the Montana Stream Protection Act, and allpermits will be obtained prior any in-channel work.
• Fuels: Implementation activities will be coordinated to avoid conflicts withfuels treatments andfuturesuppression access. Equipment shall operate in compliance with fire restrictions.
• Heritage: Heritage staff will survey proposed decommissioned routes and project implementation willonly proceed with clearance from Helena National Forest Heritage staff If cultural sites are identifiedby Heritage staffprior to implementation, those sites will not be disturbed. If cultural sites are identifiedduring implementation, actions will be halted until cleared by Heritage staff
• Hydrology: Project activities will occur only when soil is dry. For cut/fill roads, the cut material will beused to fully re-contour the slope to pre-construction conditions. All drainage features ondecommissioned roads will be restored to natural contours. All National Core Best ManagementPractices will be followedfor road decommissioning, and any in-stream work. Prior to activities,applicable permits will be obtained in compliance with the Clean Water Act and the Montana StreamProtection Act. A designated Forest Service representative responsible for maintenance of water qualitywithin appropriate state standards will oversee implementation within the municipal watershed.

• Minerals: Road decommissioning may be delayed or completed by the EPA to accommodate mine wasteremoval activities. Road decommissioning may also be delayed to allow EPA to remove abandonedwells.
• Sensitive Plants: Several sensitive plant species are known to exist in the areas. To mitigate any impactsto whitebark pine (Pinus albicaulis), ailfive-needle pines will be avoided and/or left undisturbed.Analysis of this project area for sensitive plants and habitat will occur prior to project implementationduring the 2015 field season. Should any sensitive plants be found in project area, a buffer would beestablished around each plant population as a no-entry zone for equipment. A 100-foot no-herbicidebuffer would be established around known populations.
• Soils: For two-track, the disturbed area will be ripped where needed to restore infiltration capacity andsoil productivity to the roadbed. Native material will be laid over the freshly disturbed sites to shieldagainst erosion and deter additional unauthorized use by motorized vehicles. Entrances will be blockedusing trees, boulders, etc. where feasible to deter use by motorized vehicles. Scarified and disturbedsoils will be seeded with a certified-weed-seed-free native seed mixfor short-term erosion protection.
• Timber!Vegetation: All cut vegetation will remain on site and some cut vegetation will likely be used toimprove road closures. Decommissioning activities will minimize damage to live trees and creation ofhazard trees. Any tree damaged (roots or stem) during the process will be cut to eliminate presence ofhazard trees.
• Weeds: In areas of invasive species infestation, weed control will occur before and afterdecommissioning to prevent the spread and return of invasive species (Helena National Forest NoxiousWeed Treatment ROD, 2006). All equipment will be washed prior to entering Forest Service land toprevent the spread of noxious weeds. Equipment will be cleaned prior to leaving the project areas ifoperating in areas infested with new invaders. Helena National Forest personnel will monitorimplementation effectiveness following treatments, and recommendfollow-up treatments as needed.
• Wildlife: If goshawks are detected during implementation, a wildlife biologist will be consulted. If anactive nest is located in the project vicinity, a work restriction periodfrom April 15 to August 15 will beimposed. Ifpreviously unidentified elk calving and nursery areas are located prior to or during projectimplementation, these areas will be protectedfrom disturbance (late May through July unless surveysindicate areas are no longer being used). Ifpreviously unidentified bighorn sheep lambing and nurseryareas are located prior to or during project implementation, these areas will be protectedfromdisturbance (April 15 through June 30 unless surveys indicate areas are no longer being used). Tominimize disturbance to elk and hunters during the general hunting season, decommissioning activitieswill not take place between October 15 and December 1.
This action is categorically excluded from documentation in an environmental impact statement (EIS) or anenvironmental assessment (EA). The project area and actions have been reviewed by an interdisciplinary teamthat identified and documented the potential environmental effects and determined that these actions fall withinthe category 36 CFR 220.6(e)(20) (Activities that restore, rehabilitate, or stabilize lands occupied by roads andtrails, excluding National Forest System Roads and National Forest System Trails, to a more natural conditionthat may include removing, replacing, or modifying drainage structures and ditches, reestablishing vegetation,reshaping natural contours and slopes, reestablishing drainage-ways, or other activities that would restore siteproductivity and reduce environmental impacts.).
I find that there are no extraordinary circumstances that would warrant further analysis and documentation in anEA or ElS. Under 36 CFR 220.6(b) and FSH 1909.15(3 1.2), extraordinary circumstances are defined as those

resource conditions that should be considered in determining whether extraordinary circumstances related to aproposed action warrant further analysis and documentation in an EA or an EIS and that the mere presence ofone or more of these resource conditions does not preclude use of a categorical exclusion. It is the existence of acause-effect relationship between a proposed action and the potential effect on these resource conditionscoupled with the degree of the potential effect that determines whether extraordinary circumstances exist.
I took into account resource conditions (identified next) as listed under 36 CFR 220.6(b)(1) and FSH1909.15(31.2), the anticipated effects of the proposal and the input received during ‘scoping’ in determiningwhether extraordinary circumstances might exist:
• Federally listed threatened or endangered species or designated critical habitat, species proposedfor Federal listing or proposed critical habitat, or Forest Service sensitive species.
A. Plants —there are no threatened or endangered species listed on the Helena National Forest, andalthough project implementation may impact individual sensitive plant species (listed below) orhabitat, it will not likely contribute to a trend towards federal listing or loss of viability to thepopulation or species.

A No Effect/Impact determination has been made pertaining to all but one sensitive species ofthe Helena National Forest. Based on an assessment of impacts to the Boreal toad, this projectmay impact individual or habitat in the short-term but is unlikely to add to a trend for federallisting or loss of viability to the population or species. The long-term effects from road closureand/or restoration are anticipated to improve Boreal toad habitat. Regarding wildlife, noextraordinary circumstances exist.

C. Fisheries - A No Effect/Impact to Fisheries determination has been made, therefore noextraordinary circumstances exist. Westslope cutthroat trout and western pearishell mussels donot occur in the project area, nor does western pearlshell habitat exist within the drainage. Theproposed project area is located outside of the natural range of bull trout.
• Flood plains, wetlands, or municipal watersheds — Resource protection measures will minimize short-term negative effects to wetlands or riparian areas. Road decommissioning implemented with the listedresource protection measures should benefit the Tenmile Municipal Watershed by reducing road densityand eliminating potential sources of sediment to the stream system. No extraordinary circumstancesexist for floodplains, wetlands, or municipal watersheds related to this project.
• Congressionally designated areas such as wilderness, wilderness study areas, or nationalrecreation areas — The project area is not within or adjacent to a wilderness area or wilderness studyarea. The Continental Divide National Scenic Trail (CDNST) is adjacent to the project. If any disruptionto the trail is to occur, temporary detours will be put in place and will not exceed more than two days.Project work is not anticipated to negatively impact the long-term scenic quality of the CDNSTtherefore no extraordinary circumstances exist.
• Inventoried roadless areas or potential wilderness areas — Proposed activities will remove 0.25 milesof road from inventoried roadless areas (IRA) in the Jerico Mountain IRA (see maps in Attachment A).The presence of these roads affects the naturalness and solitude of the inventoried roadless area. Projectactivities are not anticipated to negatively impact the long-term roadless characteristics therefore noextraordinary circumstances exist.
• Research natural areas — There are no research natural areas in or near the project area, and thereforeno extraordinary circumstances exist.
• American Indians and Alaska Native religious or cultural sites - There are no known sites in theproposed area. If unknown sites were encountered during implementation, these sites would be subjectto appropriate Tribal Historic Preservation Officer review and comment, as per the 36 CFR 800compliance process.
• Archeological sites, or historic properties or areas — Portions of the project area have been previouslysurveyed for archeological resources. Surveys would continue and would be completed prior toimplementation according to the National Historic Preservation Act. Any undocumented archeologicalresources found during project implementation would be reported to a Forest Service archaeologist and,if necessary, project design would be modified to avoid any impacts to those resources.
