• Contractor shall perform the following regarding for cultural resource protection:

o All operations shall be conducted in such a manner as not to cause damage or disturbance to any archaeological or paleontological resource, or places of cultural or religious significance. The Antiquities Act (1906), National Historic Preservation Act (1966), Federal Land Policy and Management Act (1976), Archaeological Resources Protection Act (1979), Paleontological Resources Preservation Act (2009), and general United State property laws and regulations all prohibit the appropriation, excavation, collection, sale, or destruction of any historic properties or objects, or vertebrate fossils situated on lands owned or controlled by the United States Federal Government (54 U.S.C. 320302; 54 U.S.C. 300101 et seq.; 43 U.S.C. 1701 et seq.; 16 U.S.C. 470aa-470mm; 16 U.S.C. 470aaa; 43 U.S.C 1733(a); 18 U.S.C. 1361; 18 U.S.C. 641; 43 CFR 8365.1). This includes both prehistoric and historic archaeological sites and associated artifacts, including but not limited to stone tools, modified bone, antler, ivory, or wood material, campfire rings, stone cairns, cabins and other structures and their ruins, mining equipment, refuse dumps, etc., as well as vertebrate fossils (the bones of prehistoric animals). Should any such site be discovered during the course of field operations, the permittee must avoid impacting the location and materials, and will immediately notify the BLM Contracting Officer’s Representative (COR) and provide GPS coordinates and photographs of the identified resource(s).

o Comply with any areas buffered for avoidance by BLM.

Wildlife Protection

• Contractor will restrict vegetation removal as directed by BLM, if necessary, between the dates of May 1 to July 15 for migratory birds.

Public Safety

• Contractor shall coordinate with BLM when working near trails and provide measures for public safety, including but not limited to a sign(s) and a flagger(s).

• Contractor shall not conduct any operations between the dates of September 20-22 annually.

2.0 Objective

The objective of this project is to remove all solid waste, hazardous waste (if present), and contaminated soil at the three sites.

The contractor shall create a work plan describing removal methods, sampling plans, and deliverable due dates to meet the requirements in this Statement of Work (SOW). The contractor can access the sites via Ester Dome Road and St. Patrick Road. The contractor shall complete removal of all solid waste, hazardous waste (if present) and contaminated soil 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 all road-accessible within 10 miles from Fairbanks. The three sites contain the materials described in section 1.0 Background.

The contractor shall provide all personnel, equipment, tools, materials, supervision, and any other items necessary to perform removal services as defined in this SOW. Any permits required shall be obtained by the contractor prior to commencing field work. All materials removed from the Ester Dome Sites shall be disposed of within Alaska Department of Environmental Conservation (ADEC) or Environmental Protection Agency approved disposal facilities. All scrap metal shall be recycled at a reputable facility.

The U.S. Bureau of Land Management shall furnish no equipment. A map and photographs of the Ester Dome Sites are attached.

All removal actions taken within this SOW shall be completed no later than September 30, 2025.

3.1 Work Plan

The Work Plan shall be completed as outlined in section 4.1 Work Plan. The Plan shall include project timeline, personnel, equipment, and methodology.

3.2 Removal

All solid waste, hazardous waste (if present), and contaminated soil shall be removed from the site and disposed of in an ADEC approved facility. The locations of all removed materials shall be logged and summarized in the final report.

3.3 Sampling

Any indication of soil contamination, or soil found near or under removed drums, motor oil containers, vehicles, etc. shall be tested for gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), and total petroleum hydrocarbons (TPH). A minimum of three soil samples plus one uncontaminated background sample shall be taken from each location of suspected contamination.

Areas with contaminated soil will be inspected prior to excavating the soil. The area of known contamination is near the drum located on Site 2. If new indications of contaminated soil are observed at other sites, sampling and removal of contamination shall occur. Any evidence that a release of contaminants has occurred will first be verified by the field crew by screening the soils with a photoionization detector (PID) in accordance with the Alaska Department of Environmental Conservation (ADEC) Field Sampling Guidance procedures (2022).

Excavation will occur using either a skid steer or by hand, and soil will be loaded into an approved container for small quantities of soil (Table 6). The soil containers will be transported to the base of operations placed in a dump truck for offsite disposal. An ADEC Contaminated Media Transport and Treatment or Disposal Approval Form will be completed and accompany the excavated soil containers and/or supersacks.

Following removal of contaminated soil, field screening will ensure no further contamination remains in the area of excavation and confirmation samples will be collected. Based on previous sampling results, confirmation samples will be collected for analysis of gasoline range organics (GRO) and diesel range organics (DRO) by ADEC determination methods AK101 and AK102, respectively (ADEC, 2016). The location, condition, and dimensions of the area and sample collection points will be mapped, photographed, and described. Once the excavation is complete, soil determined to be clean by field screening will be used as backfill and the area will then be contoured to as near as original condition as possible.

3.5 Removal Report

The removal report shall be completed as outlined in section 4.2 Removal Report.

4.0 Deliverables

Deliverables shall be submitted as a hard copy or digital copy emailed to the BLM COR. If submitting a hard copy, it shall be mailed or dropped off at 222 University Avenue, Fairbanks, AK 99709.
