Public Comment on the Summary of the Initial Project Description Project: Beacon AI Centers Indus Project (Reference #90121)

January 24, 2026 To whom it may concern, I am writing to formally submit my concerns regarding the proposed Beacon AI Centers Indus Project

·  Junior Water License Vulnerability: The project’s reliance on a 2025/2026 junior water allocation from the Bow River system (via Langdon Waterworks) poses a critical risk. Under the Alberta Water Act and the Master Agreement on Apportionment, this "Junior" license is subject to mandatory suspension if the Bow River falls below the Water Conservation Objective (WCO) of 45 m3/s. During the 2025 drought, the river hovered within 3 m3/s of this "kill switch." The Agency must assess the viability of a project that could be legally ordered to cease operations during the very peak of summer heat when cooling needs are highest.

·  Competition for Potable Water: The project’s daily draw of 1,500 m3 (approx. 0.4 million gallons) comes from the same treated potable system that supplies the Hamlet of Langdon including future expansions . In severe drought conditions (Stage 3 or 4), this places industrial cooling in direct competition with human health, sanitation, and residential needs. That the Town of Langdon future expansions are affected due to fact that Langdon’s new water agreement was signed  after Beacon’s agreement which under Alberta law FITFIR both ground water/river draws must satisfy Beacon data first in the event of another drought .

·  Fire Protection and System Pressure: The project includes an on-site reservoir (estimated at 1.2 million gallons), yet it is unclear how this volume is prioritized. I am concerned that during a drought-induced system failure, the high-volume requirements of the data center's cooling and fire suppression systems could compromise the municipal water pressure required for local firefighting and emergency services in the Hamlet of Langdon and the Indus area.

·  Cumulative Aquifer Stress: While the project proposes to use surface water, any failure or suspension of that supply (due to river drought) would likely force a reliance back on local groundwater. Given that the regional aquifers are already stressed by the 2025 drought, the cumulative impact of this facility on the Paskapoo and Lacombe aquifers must be studied. Since in 2025 a once in 140-year drought across a 100 km2 area centered on Indus which inferred a 2-meter drop in a Paskapoo sand channel (assuming 15% effective porosity) which represents a loss of roughly 30 billion liters of stored groundwater

·  That the company “requires 750m3 per day will be required for ancillary uses(HRSG makeup water, fire protection reserves, domestic water maintenance”  which amounts to 273,973,500 million litres of water/year which there is no source available except maybe ground water not applied for. The agreement they have with Langdon Waterworks only covers the water demands of the power plant and no there are no additional water agreements in place(Dec 29,2025 – Beacon AI Centers- Indus Project – Impact Assessment Agency of Canada-Section 9.7 Ancillary Infrastructure)
