Inactive Well Site Closure Portfolio

Inactive Well Site Closure Portfolio

In Northeast British Columbia, approximately 10,000 oil and gas wells have become inactive for economical or technological reasons creating significant environmental liability for oil and gas producers. A large producer in the region retained Matrix to manage an area-based portfolio of inactive well sites and progress the sites from their current status through site screening, site investigation, remediation, Certificate of Restoration (COR) Part 1 application, forested and agricultural land restoration, post reclamation assessments, and COR Part 2 application. Matrix works on approximately 150 sites/year within this portfolio.

West Eau Claire Park Public Realm Plan

West Eau Claire Park Public Realm Plan

West Eau Claire Park is a popular area along the Bow River, just north and west of downtown and near the iconic Peace Bridge. The City of Calgary wished to connect the community with the Bow River and also provide important flood protection for downtown Calgary. The park was redeveloped through widening and raising the existing pathway, protecting and enhancing the river bank, and grading and landscaping the south overbank area to protect against a 1:200-year flood event with 0.5 m of freeboard.

Golden Ranches conservation area: Assessment and remediation

Golden Ranches conservation area: Assessment and remediation

Alberta Conservation Association (ACA) is a non-profit organization that conserves, protects, and enhances ecological habitats for the benefit and enjoyment of the public. A land donation from a ranching family led to ACA and its partners having the opportunity to assume 1,350 acres of valuable grassland, aspen forest, and lake shoreline in the Beaver Hills UNESCO Biosphere Reserve east of Edmonton, Alberta. Golden Ranches provides important habitat for upland birds, waterfowl, white-tailed deer, and moose.

Frenchman River Reconnection Project for Trout Unlimited Canada

Frenchman River Reconnection Project for Trout Unlimited Canada

PROJECT SUMMARY
As part of their Reconnecting Canada initiative, Trout Unlimited Canada (TUC) identified an opportunity to address an obstruction to fish passage in the Cypress Hills Uplands region of Southwestern Saskatchewan. The Frenchman river reconnection project aimed to solve the issue of lost connectivity that had been created by scour at the outlets of several hanging culverts within two tributaries of the Frenchman River: Caton Creek and Davis Creek. The purpose of the project was to increase available habitat for threatened Plains Sucker (formerly known as Mountain Sucker) populations, improving their ability to adapt to the growing pressures of climate change and habitat loss. Changes to water flow and fish passage are described as threats to Plains Sucker populations as is genetic fragmentation created by improperly designed or failed infrastructure. These fish play an important role in the ecosystems that they inhabit.

Drumquin Park Weir Removal and Channel Enhancements

Drumquin Park Weir Removal and Channel Enhancements

In collaboration with Enbridge and the Town of Milton, Conservation Halton undertook a priority environmental project to decommission the existing Drumquin Park weir on East Sixteen Mile Creek and restore the natural channel function and habitat. Sixteen Mile Creek provides aquatic habitat to many species including the Silver Shiner, a species classified as at risk in Canada and threatened provincially. Removal of the Drumquin weir provides the opportunity to restore connectivity to downstream occupied Silver Shiner habitat and rehabilitate degraded Silver Shiner habitat – actions that address the various recovery objectives for this threatened species.

We routinely lead characterization of stream morphology to:

  • Assess fluvial erosion hazards
  • Develop alternatives for erosion control in environmental assessments
  • Develop management strategies as part of land use planning (subwatershed, secondary, tertiary plans and site plans)
  • Assist in culvert/bridge design
  • Define erosion thresholds to inform stormwater management
