From Aecon Seeks Approval for Contentious Gravel Quarry in Alberta

How could the review of Aecon's quarry approval affect the Government of Alberta?

Possible What happens if… A possibility worth considering, not a forecast.

Government of Alberta faces regulatory challenge over controversial gravel quarry permit The Government of Alberta's initial approval for Aecon's 81-hectare Summit Quarry is currently under review by the Environmental Appeal Board. Opponents argue that the quarry, located 800 metres northwest of Big Hill Springs Provincial Park, poses severe environmental risks, including exposing the creek's aquifer to arsenic, chromium, and selenium. If the Board reverses or amends the July 2023 Water Act approval, it would represent a significant reversal of the Government of Alberta's regulatory decision regarding the project's environmental protection.

The facts so far

As reported. Each one links to where it comes from.

  • The provincial government granted Water Act approval for Aecon’s 81-hectare gravel quarry in July 2023.calgaryherald.com
  • The quarry is located 800 metres northwest of Big Hill Springs Provincial Park.calgaryherald.com
  • Opponents warn that removing topsoil and gravel could leave the creek vulnerable to seeping arsenic, chromium, selenium, and hydrocarbons.calgaryherald.com
  • The Environmental Appeal Board hearing is currently taking place.calgaryherald.com

Why it matters

The approval of large-scale resource extraction projects is a core function of the Government of Alberta, balancing economic development against environmental protection. The Summit Quarry is contentious because it threatens a tiny, 70-year-old provincial park treasured for its unique tufa formations and thermal springs.

This case highlights the ongoing tension between industrial activity and conservation in the province. The Alberta environment ministry had previously expressed concerns about potential groundwater effects in a February 2021 letter to Rocky View County Council, indicating that environmental risks have been a long-standing point of debate.

What we don't know yet

  • Will the Environmental Appeal Board uphold the July 2023 approval or mandate amendments?
  • What specific scientific data will be used to determine the risk of groundwater contamination?

What would change this answer

The Environmental Appeal Board mandates significant changes to the project design.This would force the Government of Alberta to revise its regulatory framework for similar future projects, potentially increasing oversight.
Aecon successfully demonstrates that the pit is a dry pit at least one metre above the established high water level.This would strengthen the Government of Alberta's position that the initial approval was adequately protective and appropriate in the circumstances.
