1.0 PROJECT OVERVIEW

1.1 Summary of Work

The primary objective of this project is to replace heating oil tanks and associated system components that provide heating to four housing units managed by Bering Land Bridge National Preserve (BELA), a unit of the National Park Service (NPS) in Nome, AK.

This work consists of the following major elements:

• Submission of product and planning data for NPS approval,

• Procurement of new heating oil tanks, including appropriate appurtenances and connections,

• Transportation of tanks and attachments to the Project Site,

• Removal of existing tanks on site,

• Final disposal of removed tanks,

• Installation of new heating oil tanks, including appropriate appurtenances and connections,

• Provision of appropriate manuals and warranties, and

• Overall project management.

1.2 Project Location

Bering Land Bridge National Preserve (BELA) is located on the Seward Peninsula on the western coastline of Alaska. The Preserve is headquartered in Nome, AK, located approximately 540 miles northwest of Anchorage, AK and accessible via commercial jet flight.

All four facilities requiring heating oil tank replacement are in Nome. They are:

• NPS Bunkhouse, located at 507 W 4th Avenue. This two-story bunkhouse is served by one tank on the north side of the building. The fuel tank is guarded by two bollards.

• Warren Residence, located at 500 W C Street. This single-family home is served by one tank on the east side of the building. There are two bollards protecting the fuel tank.

• Duplex 205, located at 205 E 5th Avenue. This duplex is served by one tank located on the northwest corner of the building. The fuel tank is surrounded by a fence on two sides.

• Duplex 203, located at 203 E 5th Avenue. This duplex is served by one tank located on the northwest corner of the building. The fuel tank is surrounded by a fence on two sides.
