Umiat: Contaminated Soil Removal and Test Well Plug and Abandonment, Umiat, Alaska

From 2009 through 2013, the U.S. Army Corps of Engineers (USACE) selected Marsh Creek on multiple contracts to complete excavation, transportation and disposal of nearly 10,000 tons of PCB-contaminated soil from a remote oil exploration drill site in the foothills of the Brooks Range in the National Petroleum Reserve-Alaska (NPRA). The contracts included seasonal planning and permitting, ice road and ice bridge construction, remote camp operations, mobilization and demobilization of more than 500 tons of heavy equipment, sampling and analysis of more than 4,000 analytical samples, operating an onsite ADEC- and ELAP-approved mobile laboratory, maintaining a GIS database, completing as-built surveying, annual completion reporting, and performing a geophysical investigation at the former Umiat landfill. Our work on these contracts also included coordinating with the Alaska Oil and Gas Conservation Commission and the Bureau of Land Management (BLM) to properly plug and abandon Umiat Test Wells No. 6, 7, and 9. Over the course of these contracts, Marsh Creek logged more than 130,000 miles of overland winter travel with zero lost time incidents. Marsh Creek was selected by the BLM to perform work under their Legacy Well Restoration Program in the NPRA.
The first phase was an emergency response at the J.W. Dalton #1 test well on the shoreline of the Beaufort Sea. Removing the drilling waste and plugging and abandoning (P&A) the exploration well became a top priority for the BLM after 345 feet shoreline eroded in the 4 weeks before freeze-up of the Beaufort Sea in fall 2004.

From 2006 through 2011, Marsh Creek continued to support the BLM’s Legacy Well work including site characterization and closure work at three other NPRA drill sites (East Teshekpuk, Atigaru Point, and Drew Point). Characterization findings were used to develop a plan to consolidate drilling waste from the sites into a single temporary storage cell until a more economical disposal option becomes available during future exploration or full-field development activities. Work at these sites included:

  • Mobilizing each season by cat-train a 40 person camp, up to 20 pieces of heavy equipment, and 100,000 gallons of fuel
  • Obtaining project permits and providing runway lights and a weather observation building
  • Constructing an onsite 3,500-foot long ice runway at East Teshekpuk and Atigaru Point
  • Operating interim storage facilities at Ikpikpuk and North Kalikpik
  • Removing, transporting and disposing of 19,000 cubic yards of drilling waste
  • Constructing and maintaining approximately 50 miles of ice roads
  • Removing and recycling of metallic debris

Brownlow Point: Drum Project at the Brownlow Point and Jago River FUDS

Marsh Creek was contracted by the USACE to complete a drum removal action and remedial investigation at the Brownlow Point and Jago River Formerly Used Defense Sites (FUDS) within the Arctic National Wildlife Refuge. Over 1,400 drums were removed from the Jago River site using a Robinson R44 helicopter to sling load drums to Kaktovik, Alaska where they were crushed, barged to Deadhorse and trucked to Fairbanks for recycling. For the Brownlow Point site, 50 drums were flown to Kaktovik using the R44 helicopter; however, adverse weather prevented the summertime removal of an additional 80 drums and 35 cubic yards of POL-contaminated soil. Remaining drums and contaminated soil at the Brownlow Point site were removed April 2011 when the site was accessible via winter overland and sea ice travel. The project team received the Secretary of the Army’s Award for Environmental Restoration for work at the Jago River site. Work at the Jago River and Brownlow Point sites included:
  • Obtaining project permits and preparing planning documents
  • Conducting a FLIR survey/thermal imaging investigation required by USFWS to verify the absence of polar bear dens along the bluffs before the winter drum removal and soil excavation work
  • Mobilizing/demobilizing heavy equipment, camp facilities, materials, and personnel using barge, fixed-wing aircraft, and cat-train (overland and sea ice) to support the summer and winter fieldwork
  • Field screening 1,535 locations for petroleum hydrocarbons and collecting laboratory samples
  • Excavating, transporting, and thermally treating 50 tons of petroleum-contaminated soil
  • Containerizing, manifesting, transporting, and disposing of 450 gallons of mixed liquid waste from the two sites

Fort Wainwright: Environmental Investigations at Various Sites, Fort Wainwright, Alaska

Marsh Creek was contracted by the USACE under an Environmental Remediation Services (ERS) Contract to complete the environmental investigations and prepare closure documents for various sites located on Fort Wainwright, Alaska. Environmental Investigations planned under this project include Preliminary Source Evaluations (PSE) at four sites, Remedial Investigation/Feasibility Study (RI/FS) with Risk Assessments at seven sites, and a Data Gap Analysis (DGA) at the Birch Hill USTs site. Current tasks also include an Explanation of Significant Differences (ESD) for Operable Unit 5, a Proposed Plan (PP) and Record of Decision (ROD) for four sites, and an Explosive Safety Submission (ESS). Marsh Creek with subcontractor Weston Solutions, has prepared the Project Management Plan, the Work Plan and other planning documents, and will be mobilizing for fieldwork in June 2015.
