Petroleum Remediation

Tommy Lakes, Canada

Ice roads assisted in allowing the team to access the remote, heavily forested site
Deployment was February 1, 2024. The first phase of the project was complete by the end of March 2024
Four Enhanced Thermal Conduction (ETC) cells treated 9800 tons of contaminated soil in less than 40 days

Treatment exceeded specifications
On-site treatment allowed the soil to remain in place
Land is returned back to Blueberry River First Nation, Halfway River First Nation, Ft. Nelson First Nation & Prophet River First Nation

Legacy wellsite and remote sump remediation
Site impacts a result of historical drilling operations
Site located on First Nations land located near Waterton Lakes National Park in Southwest Alberta
Remedial activities consisted of site preparation, soil handling and thermal soil treatment

Three ETC systems deployed to location for onsite treatment
Treatment turnaround times of 7-8 days per cell with approximately 2,400 tons per week of clean, treated soil generated from the three ETC systems
Local personnel from the First Nation’s community integrated into the onsite operations crew
Approximately 26,400 tons of material remedial in 2021 with an estimated 30,000 tons scheduled for ETC processing commencing in Q2 2022
Desorbed soil impacts adding to the ESG value chain by being utilized as system fuel to supplement energy inputs for the ETC process
All weather, all season, operations

Thermally treat the soil to eliminate contingent liability related to soil impacts at the site
Engage local First Nations members as part of the operational deployment to provide additional value to the community
Clean, treated soil to remain onsite to be utilized as backfill and eliminating the need to import soil to the site
Site will be ready for surface reclamation upon completion of the thermal soil treatment activities

Legacy WWII-era former refinery site containing extremely high concentrations of heavy hydrocarbon waste, including free product tar
Located in the middle of the City of Whitehorse, and surrounded by residential communities as well as commercial & industrial development

Approximately 36,000 tons of heavily impacted soil were thermally treated at the site, through all seasons
Impacts consisted of LEPH10-19 (Light Extractable Petroleum Hydrocarbons), HEPHC19-C32 (Heavy Extractable Petroleum Hydrocarbons), and PAH impacts all exceeding

Thermal treatment had improved results allowing revision of target criteria to Yukon CSR Commercial/Industrial limits
On-site treatment removed the liability from treated material and approximately 1,000 truckloads of soil were kept off roads & diverted from landfills

Impacted soil excavated and placed in two 850 m3 ETC Treatment cells
LPG is used for burner fuel
High levels of ambient Benzene required customized treatment
Treatment cell turnaround times ranged from 4 to 6 days per cell
24/7 remote temperature and video monitoring ensured treatment goals were reached

Impacted soil excavated and placed in 850 m3 ETC Treatment cell
The second treatment cell was constructed while treatment was underway on the primary cell
LPG is used for burner fuel
Treatment cell turnaround times ranged from 4 to 6 days per cell
24/7 remote temperature and video monitoring ensure treatment goals were reached

The treatment was successfully completed in approximately 6 months.
All post-treatment samples were below the required standards
Treatment commenced in the rainy season and ran into the extreme cold of January
Liability was removed and closure was achieved at the site

The treatment was successfully completed in four weeks
Post Treatment analysis confirmed all samples met Yukon CSR guidelines for hydrocarbons
Liability was removed and closure was achieved at the site
