From Aecon Seeks Approval for Contentious Gravel Quarry in Alberta

How could the contentious gravel quarry application affect Grant Hunter?

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

Minister Grant Hunter faces pressure over controversial quarry approval in Alberta The application for the Summit Quarry, an 81-hectare gravel pit, has generated significant public and scientific opposition regarding its impact on Big Hill Springs Provincial Park. Opponents argue that removing 25 metres of topsoil and gravel risks exposing the creek’s aquifer to toxins like arsenic and chromium. While the ministry initially granted Water Act approval in July 2023, the ongoing hearings and expert testimony place the Minister of Environment, Grant Hunter, at the center of a high-stakes regulatory debate over the adequacy of the environmental assessment.

The facts so far

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

  • The proposed quarry is 81 hectares and located 800 metres northwest of Big Hill Springs Provincial Park.calgaryherald.com
  • Opponents warn that removing 25 metres of topsoil and gravel leaves only one metre of material atop the creek’s aquifer.calgaryherald.com
  • Concerns include the creek becoming vulnerable to seeping arsenic, chromium, selenium, and hydrocarbons.calgaryherald.com
  • The Alberta environment ministry expressed concerns about the potential groundwater effect in a February 2021 letter.calgaryherald.com

Why it matters

The quarry represents a conflict between industrial development and the preservation of a sensitive, 70-year-old provincial park treasured for its unique tufa formations and thermal springs. If the quarry proceeds, the local community and environmental groups fear a permanent alteration of the area's delicate ecological equilibrium and a threat to local water wells.

For the Minister of Environment, this situation tests the regulatory framework of the province. The Minister's office must balance the economic interests of quarrying companies like Aecon against the scientific warnings regarding groundwater contamination and the public's demand for environmental protection.

What we don't know yet

  • Will the Environmental Appeal Board reverse or amend the 2023 Water Act approval?
  • Will new scientific data be presented that changes the assessment of groundwater risk?

Is this still moving?
