Soil Remediation Project Updates


Overview

The Soil Remediation Project resumed in April 2024 to remove niobium ore tailings from the former Nova Beaucage mill site in Yellek. The mill operated for seven months in 1956, and its tailings were deposited at the former gravel borrow pit north of Highway 17 (next to the Anishinabek Nation head office), and used in road construction and as fill at various sites on Nipissing First Nation throughout the 1970s and 1980s. All impacted locations, including private residences, were identified through earlier investigations and are included in the remediation plan.


Current Status – July 2025

Work is ongoing to remove niobium-impacted material from NFN lands, with the goal of completing cleanup activities by the end of 2025.

Hauling operations to remove the stockpile from Lot 24 in the Bineshii Business Park were recently completed safely and efficiently. Approval has now been granted to continue transporting material to the Sarnia disposal site, at least until approval is received to dispose of the material at the Agnew Lake Tailings Management Area (ALTMA).

Lot 24 will continue to serve as a staging area, where material from other sites will be stockpiled using triaxle trucks and then transferred into larger end dump trucks for transport. This approach improves efficiency and reduces truck traffic.

All environmental provisions and traffic control employed during the previous works will remain in place for this continuation of the work.

Work Completed to Date

Remediation of four residential properties on NFN was completed in 2024, along with some work to remove contaminated material from the old Nova Beaucage Road allowance. The material excavated from these sites was stored on a vacant lot in the Bineshii Business Park through the winter.

In September 2024, NFN paused the excavation of any further contaminated material until approval to haul to the material to the ALTMA or another approved disposal site was in place.

In July 2025, hauling operations resumed to remove the stockpile from Lot 24, and approval was granted for continued disposal at the Sarnia facility.


NFN Work Sites & Disposal Plan

Proposed Long-Term Disposal Site: Agnew Lake Tailings Management Area (ALTMA)
Current Disposal Site: Clean Harbors facility in Sarnia (approved for interim use)

The contaminated soil that will be removed from three work sites and the four identified private residences on NFN will be hauled to an approved and regulated disposal site.

Remediation Sites:  Nipissing First Nation

Site #1:  Former Nova Beaucage Mill Site – 15,539 tonnes of contaminated material to be removed, along with concrete pad foundation.

Site #2:  Section of Nova Beaucage Road at the corner of Ernest Avenue (18 tonnes) and the old Nova Beaucage Road allowance (7,080 tonnes). This road allowance was not part of the original project scope, but we are committed to cleaning up this area.


Site #3
:  MTO Lands east of Anishinabek Nation head office – former gravel borrow pit (11,409 tonnes)

Private Residences:  224 tonnes in total ; two residences in Garden Village, one in Yellek, and one in Duchesnay.

All sites operate under Health and Safety Plans that exceed standard requirements to ensure community safety. Separate plans are in place for each work site and the disposal site.

“Irresponsible, historic actions have left Nbisiing with scars of contamination. In the 1950s, the Nova Beaucage Mill was built east of Yellek to process ore containing niobium and uranium. After only seven months of operation, the mill closed. Everything was left on site, and the radioactive, contaminated land was given back to us without any remediation. Radioactive materials from the mill were also stored at the Ontario Ministry of Transportation’s (MTO) abandoned sand pit on the north side of Highway 17. Unfortunately, ore stored at these sites was used for construction, landscaping, and roads in and around the community.” – from NFN Environmental Management Plan, Contaminated Sites Technical Tearaway

Work Site #1 – Former Nova Beaucage Mill Site, May 15, 2024

Work Site #3 – Staging Area in Bineshii Business Park (next to Anishinabek Nation head office), May 15, 2024. Installation of geotextile* matting to safely contain the material.

* Geotextile fabric is a permeable textile material that serves several functions, including separating material to prevent the mixing of different soil layers and filtration by allowing water to pass through while retaining soil particles.
