Statement of Work

Wolf Tomsha Mining Claim Clean Up and Revegetation Project Bureau of Land Management – Eastern Interior Field Office

1.0 Background

The Eastern Interior Field Office (EIFO) of the Bureau of Land Management (BLM) proposes removal actions and revegetation work at the Wolf and Tomsha mining claim sites. The mine sites are located on Bottom Dollar Creek and Ptarmigan Gulch, both of which are tributaries that feed into Harrison Creek, a tributary of the Birch Creek Wild and Scenic River (WSR). The mine sites and Birch Creek WSR are located in the Steese National Conservation Area. The site comprises two separate claim areas (Bottom Dollar and Ptarmigan Gulch). For the purposes of this Statement of Work (SOW), the Wolf site is referred to as Bottom Dollar and the Tomsha site is referred to as Ptarmigan Gulch. The claims are accessible down Portage Creek Road from Central and then down Harrison Creek Trail.

Bottom Dollar (Wolf) Bottom Dollar mine site is a closed placer claim (AKFF091100). The claim has been abandoned and void since 2012. Debris remains on the claim including a cabin structure, fuel tank, fuel shed containing fuel, motor oil, and other hazardous materials, metal pipe, scrap steel, and tiles (See Table 1).

Feature Type Notes

1 Cabin Approximately 16’ x 12’.

2** Fuel tank Large (>2000 gal), steel, likely empty or mostly empty.

3 Scrap wood Old pallets and fencing material.

4 Scrap steel Various mining equipment, structure, and irrigation materials.

5 Scrap aluminum Piping and other in 10’-20’ lengths.

6 Storage shed Approximately 8’ x 12’. Contains solid waste, hazardous materials, batteries, petroleum products, possible spillage and inadequate containment.

7 Travel trailer Approximately 15’ x 7’.

**Feature No. 2 Fuel tank is included in Option 1 below. Feature No. 2 is not included in Base Tasks.

Site Access: The site is accessed by travelling approximately 21 miles south on Portage Creek from Central, Alaska, and then down Harrison Creek Trail. The site is accessible to four-wheel drive (4WD) and tracked vehicles to the BLM boundary near the Bottom Dollar site. There is approximately 0.31 miles of trail on BLM-managed lands. On BLM-managed lands, only all-terrain vehicles (ATVs) and/or utility terrain vehicles (UTVs) are allowable in the spring, summer, and fall and snowmachines during the winter. No new trails may be created outside of winter; ATVs and UTVs may only be used on the existing trail to reach the mine site.

Ptarmigan Gulch (Tomsha) Ptarmigan Gulch mine site is a closed placer claim (AKFF091607). Claims were abandoned and voided in 1995. The BLM removed hazardous materials and solid waste in 2003; however, debris remains on the claim including a wash plant and sluice boxes (See Table 2).

Feature Number

Feature Type Notes

1 Equipment Large wash plant approximately 9 feet high.

2 Equipment Sluice box, buried in vegetation.

3 Equipment Sluice box, buried in vegetation.

Site Access: The site is accessed by travelling approximately 21 miles south on Portage Creek Road from Central, AK and then west approximately 6 miles along Harrison Creek Trail. Ptarmigan Gulch lies two drainages west of Bottom Dollar Creek. The Ptarmigan site is accessible from the Bottom Dollar site on BLM-managed lands via ATVs or UTVs on the existing trail; the existing trail does not directly reach the Ptarmigan site and during the spring, summer, and fall the site can be reached by an approximately 0.52 mile hike from the existing Harrison Creek trail as no new trails may be created outside of winter and ATVs and UTVs cannot be used off the existing trail to reach the site.

2.0 Objective

The objective of this project is to perform a non-time critical removal action of all solid waste and hazardous materials present at the Bottom Dollar-Ptarmigan Gulch mine sites and restore the disturbed land. Any revegetation will be completed with Alaska Native Flora (see 6.0 Appendix Revegetation Stipulations). This removal action shall be done in accordance with the criteria of the Bipartisan Infrastructure Law Sec. 40804(b) Subsection 8 Revegetation Mine Lands.

The contractor shall create a Work Plan including removal methods, sampling plans, and deliverable due dates.

The contractor shall complete removal of all solid waste, hazardous waste, and contaminated soil (if present) from the sites. The contractor shall log coordinates of all removed material and sampling locations. The contractor shall write a final report outlining all removal actions, sampling, and final state of the project.

3.0 Requirements

The sites are accessible on BLM-managed lands by ATV or UTV in the spring, summer, or fall or by snowmachine in the winter. For the purposes of this SOW, winter refers to conditions when there is adequate snow and ice for oversnow travel by snowmachine.

The trail to the site is unimproved, rough, and challenging. Due to this, consolidation of solid and hazardous waste will occur during spring, summer, or fall, when there is little to no snow to cover the waste and it can be readily identified. Larger vehicles than ATVs or UTVs cannot be used to haul out waste during the spring, summer, and/or fall due to the trail access and to prevent trail degradation. To prevent trail impacts and degradation, large and heavy materials should not be removed during the spring, summer, and fall.

Snowmachines with sleds/skids during the winter are allowable and recommended for waste removal haul out during the winter. Other methods of waste removal that do not impact the trail such as aviation are also allowable and will be considered.

Contractor requirements at both sites include the following:

Minimize ground disturbance

• Overland moves that are a part of contractor operations will occur during winter when frost and snow cover is sufficient to minimize vegetation and soil disturbance and compaction. The Authorized Officer will determine the date when sufficient frost and snow cover exists, and no overland moves should occur until these conditions are met.

• Construction of winter trails and ice roads for overland moves will be designed to minimize compaction of soils and breakage, abrasion, compaction, or displacement of vegetation.

• Clearing of drifted snow is generally allowed, to the extent that vegetative ground cover is not disturbed.

• Offsets of winter trail/ice road locations may be required to avoid using the same route or track each subsequent year.

• When access is required in snow-free months, routes that utilize naturally hardened sites will be selected to avoid trail braiding. Traveling through saturated soil conditions will be avoided.

• All roads and/or trails constructed to access sites, will avoid areas with unstable or fragile soil and will be designed to minimally disrupt patterns of natural drainage. Where practicable and feasible, avoid disturbance of the vegetative mat and permafrost soil areas.

• To the extent possible, contractors will employ vehicle types and methods that minimize vegetation and soil disturbance, such as use of aircraft, utilizing existing roads or trails, or use of low ground pressure vehicles.

• Rivers and streams will be crossed by vehicles in locations that minimize impacts to stream channels, stream banks, and riparian vegetation.

Revegetation (see also Appendix 6.0)

• All revegetation of surface disturbance will require an approved site-specific plan designed to achieve desired conditions and prevent the introduction of non-native invasive plants (invasive plants). These plans should describe current vegetative conditions, treatment methods, measures for preventing introduction and spread of invasive plants, and monitoring actions. Treatments will use native vegetation and seed. Mulching, erosion control measures, and fertilization may be required to achieve acceptable stabilization of surface materials. Inter-seeding, secondary seeding, or staggered seeding may be required to accomplish revegetation objectives.

• Any disturbed areas will be backfilled, topped with a native soil mixture, and revegetated by excavating plugs of native vegetation on site and placing them into the disturbed location.

• Revegetation of disturbed soils is expected to be accomplished as soon as possible after the disturbance occurs with efforts continuing until the site is stabilized.

• Soil disturbance will be reduced by minimizing footprint of surface-disturbing activities, consolidating access to minimize the number of routes, and requiring prompt implementation of methods to mitigate any soil erosion.

Invasive Species Prevention

The contractor shall ensure that all equipment, vehicles (e.g., trucks, trailers, watercraft, aircraft) shall be free of visible soil, seeds, and vegetative parts before deploying to the project site and before moving from areas of known BLM Alaska Priority Invasive Plant (PIP) infestations.

• Contractor shall not park or stage equipment, supplies, or materials in areas known to be infested with PIP. When feasible, activities shall commence from known uninfested areas and progress toward known infested areas.

• Contractor shall report any identified PIP onsite with location and description.

BLM will provide any location data and avoidance areas for BLM Alaska PIP infestations (see Table 3).

Upon final contract award, see the Standard Form 1449 for point(s) of contact.

6.0 Appendix

Revegetation Stipulations The contractor shall develop a revegetation and monitoring plan for the proposed project. The plan shall achieve the following objectives:

1. Revegetate all disturbed areas to attain approximately 70% native plant foliar cover, comprised of at least three different plant species and obtained within three growing seasons of the proposed action:

a. Plant species should be locally adapted to the project area. The harsh environments of Alaska limit species growth and production potentials. Therefore, it is imperative that species chosen are able to survive and thrive in the local environment. Climatic, topographic, and soil conditions all influence plant performance, and should all be taken into account when selecting species. See Table 3 for a list of suggested plant species for interior Alaska. Including locally adapted forbs and woody plants to revegetation mix is strongly encouraged.

b. During project operations, if uncontaminated topsoil is removed, the material should be stockpiled and used to revegetate. This layer is a source of native seed, plant propagules, organic matter, and soil microbes, which can enhance the quality of the substrate being revegetated.

c. If ground disturbance activities involve removing vegetation, the contractee should attempt to transplant as much of the removed vegetation as possible, as soon as possible. Manual or mechanical (i.e., with the use of a loader or other equipment) transplant techniques can be used.

If using heavy equipment, transplanting should include root mass of woody vegetation along with associated herbaceous vegetation. More information about revegetation techniques can be found in the Interior Alaska Revegetation & Erosion Control Guide.

d. Revegetation should be implemented as soon as possible after disturbance. If feasible, revegetate portions of the project area as ground disturbance activities progress. For example, operations are encouraged to move transplants directly from new ground disturbance areas to completed areas.

e. If using a seed mix, it must be weed-free. Contact the Division of Agriculture Alaska Plant Materials Center for assistance with selecting local, weed-free seed mixtures.
