PERFORMANCE WORK STATEMENT

U.S. FISH AND WILDLIFE SERVICE

LEGACY REGION 7 ALASKA

GENERAL

BACKGROUND:

Beaver, Alaska BIA School is located in Beaver, Alaska and the land was transferred to U.S. Fish and Wildlife and is now part of the Yukon Flats National Wildlife Refuge. Beaver, Alaska is not on the road system and can only be accessed by plane or boat. Beaver, AK is located approximately 110 miles north-northeast of Fairbanks, Alaska. The other way of reaching Beaver, Alaska, is by the Yukon River, and it is serviced by barges that bring supplies to the community.

In the fall of 2025, the BIA School Buildings were removed from the site. During this removal of the buildings a potential underground storage tank was identified. A pipe sticking out of the ground and is believed to be a fill pipe was found. The Beaver Village Council was asked if they were aware of an underground tank existing at this site. They were not aware of an underground storage tank being installed at this location.

SPECIAL CONDITIONS:

Beaver, Alaska is a remote location with limited facilities. There is no hotel or food service. Contractors have stayed in the school for a fee during the summer. All supplies and equipment necessary to perform this site survey/sampling must be transported to the site. The transportation plan to get to the remote location shall be coordinated through the Contracting Officer. The Contractor is responsible for all permits, Alaska Department of Environmental Conservation (ADEC) coordination, work plans, coordination with the Refuge, and contingencies.

Interviews with government officials shall be conducted in person, by telephone, or in writing. The contractor shall identify the key site manager who has a good knowledge of the uses and physical characteristics of the property. These interviews shall be conducted during the site visit.

Appropriate local government officials may also be interviewed to obtain the necessary information. The contractor shall keep detailed notes of all interviews. These notes shall become the sole property of the USFWS. No one shall receive copies of notes, documentations, and reports without the permission of the government.

CONTRACTOR QUALIFICATIONS: Contractor experience must be approved by the Contracting Officer and will be based upon submission of the following information by the Contractor:

1. Person(s) conducting ground penetrating surveys shall have experience conducting this type of survey.
