STATEMENT OF WORK

Landspread Monitoring at Multiple Sites

July 15, 2025

1. Introduction

The BLM performed removal actions at multiple sites in western AK. At each site, soil containing weathered diesel fuel was removed and landspread on site. The BLM is seeking to establish long term monitoring for the landspread soil at each site. The base scope of services covers a single sampling event, with associated documentation, at each site. An optional task provides for a second round of monitoring, including planning and reporting documents.

The remediated site is located approximately 84 miles SE of McGrath, AK. During 2010 the BLM discovered an abandoned drum labeled as being military JP4 in the spruce forest several hundred feet north of the Rohn (Tatitna) airstrip. The BLM removed the ½ full drum in 2022. The locations of the soil excavation and landspread are illustrated in Final Removal Action Report – Rohn Spill Site (August 2023), which is attached to this scope of work.

Bears have wallowed in the spill creating an approx. 10’x12’x1’ depression. The locations of the soil excavation and landspread are illustrated in Final Removal Action Report – Uranium2 Wanagin Spill Site (August 2023), which is attached to this scope of work.

The nearest cargo aircraft airstrip for staging is Buckland PABL
