Elk Valley Area Based Management Plan

The Elk Valley Area Based Management Plan (ABMP) is a unique watershed plan designed to help improve water quality.

The plan informs decisions in the Elk Valley made by statutory decision makers under the Environmental Management Act (EMA).

Amendments to the plan

The amendments were developed in response to a Ministerial Order that was issued on July 9, 2024. The Order required development of two amendments.

View the Ministerial Order No. M232-2024 to amend the plan.

Amendment #1 is now complete. It was prepared by the Ministry of Environment and Parks in accordance with the Order.

This is the first amendment to the plan since it was developed in 2014.

The amended plan considered input from provincial, federal and Ktunaxa First Nation governments, as well as from industry. Stakeholder and public input was also sought through a four week public comment period in May 2025.

Amendment #2

Planning for Amendment #2 is now underway. Amendment #2 will review the selenium water quality target for Koocanusa Reservoir.

On June 6, 2025, the Minister issued Ministerial Order No. M162-2025 adjusting the timeline for planning Amendment #2. Under this Order, the Terms of Reference for Amendment #2 must be submitted to the Minister by March 31, 2026.

Development of the original plan

In April 2013, Teck Coal Limited (Teck) was ordered to prepare an area based management plan for the Elk Valley to remediate water quality effects of past coal mining and to guide future development:

• April 15, 2013: A Ministerial Order (PDF, 421KB) was issued to Teck
• July 22, 2014: Teck submitted an area based management plan called the Elk Valley Water Quality Plan (PDF, 41.7MB)
• November 18, 2014: The Minister approved the plan (PDF, 147KB)

Plan overview

The plan was developed with the following objectives and outcomes for the area it applies to, which includes the Elk River watershed and the Canadian portion of Koocanusa Reservoir:

• Protection of the aquatic ecosystem health
• Management of bioaccumulation of contaminants in the receiving environment
• Protection of human health
• Protection of groundwater

The plan is focused on stabilizing and reducing concentrations of selenium, cadmium, nitrate and sulphate in the Fording and Elk Rivers and the rate of formation of calcite.

Specifically, the plan:

• Sets short, medium and long-term targets for selenium, cadmium, nitrate and sulphate in water and for the reduction of calcite
• Identifies water quality mitigation measures, including water treatment and diversions, and defines a schedule for implementation
• Includes an adaptive management approach to ensure that the plan evolves with monitoring information, outcomes of research and development, and advances in science and technology
• Incorporates ongoing monitoring to assess water quality and aquatic health during the implementation of the plan to confirm objectives are met

The plan provides guidance to statutory decision makers and staff under the EMA as they manage existing discharges and consider future discharge proposals in the Elk Valley.
