Elk Valley Area Based Management Plan

Area Based Management Plans

Area Based Management Plans (ABMP’s) in B.C. are developed under the Environmental Management Act.

The plans identify environmental management objectives and strategies to help manage waste discharges in a specific area.

The Elk Valley Area Based Management Plan is being used to manage historic and current waste from multiple mines in the Elk River watershed.

In 2013, the B.C. Minister of Environment issued a Ministerial Order to Teck Coal Ltd., now EVR Operations Ltd. (EVR), owner of the active coal mines in the Elk Valley.

EVR was ordered to develop an Area Based Management Plan (ABMP) for the Elk Valley to:

Improve water quality
Guide future mine development

When developing the plan, called the Elk Valley Water Quality Plan, EVR:

Engaged with key stakeholders
Consulted with a technical advisory committee
Compiled and assessed current science and technology
Used impact assessment, risk assessment and planning tools
Identified water quality targets at sites throughout the watershed
Developed a water management and treatment strategy to meet the water quality targets

EVR’s Elk Valley Water Quality Plan (EVWQP), was completed and approved in 2014.

The plan identified long term water quality targets throughout the watershed and described the actions EVR needed to achieve the plan goals and meet water quality targets. The plan also included commitments to:

Research and develop more water quality management options
Monitor water quality and aquatic health
Manage adaptively so that the latest data and science is being considered
Report and consult with stakeholders and the public

In 2025, the B.C. Ministry of Environment and Parks amended the original 2014 EVWQP in accordance with a Ministerial Order issued in July 2024. The 2025 EVWQP was approved by the Minister as the Elk Valley ABMP in July 2025. The updated plan is written by the government and applies to all dischargers in the watershed. It describes the long term goals for the watershed and confirms the water quality targets that were set in 2014. It gives guidance on how to achieve the goals and targets, and establishes a process to keep the plan up to date.

Elk Valley Water Quality Plan goals

The EVWQP is a strategy for managing water quality at a watershed scale. It includes historic and current waste from multiple mines in the region. The plan protects the overall health of larger aquatic ecosystems in the Elk River watershed.

The EVWQP informs ongoing decisions and actions to improve water quality in the Elk Valley. The Minister of Environment and Parks has required that all the ministry’s permitting and regulatory decisions in the Elk Valley are informed by the plan.

Targets

The water quality targets in the EVWQP allow for higher amounts of certain mining-related substances in some parts of the watershed. Scientific assessments showed that ecosystems at a regional scale will still be protected. Additionally, local effects could be monitored and responded to. The benefits and risks of this approach were comprehensively evaluated.

The plan is designed to improve water quality in the Elk Valley. The plan relies on new treatment technologies to address historical impacts and to ensure that new impacts are avoided or treated at the start. It also commits to better controlling the sources of substances that may be harmful to the environment.

Learn more about water quality targets, including how they were set and the levels that were chosen.

Adaptive management

The EVWQP recognizes the need to adapt and respond to new information. The plan supports continuous improvement over time using an adaptive management approach.

Elk Valley Permit 107517

Waste discharge permits

Waste discharge permits are legal instruments that are issued by the ministry under the Environmental Management Act.

Permits authorize the discharge of waste into the environment, subject to terms and conditions related to:

Generation and handling of waste on a site
Where and how waste is discharged to the environment
Quality and quantity limits on waste
Types and amounts of waste released
Environmental monitoring where the waste is released

Following approval of the EVWQP, key commitments and requirements were incorporated into a new valley-wide waste discharge permit.

Permit 107517 was issued to EVR in 2014. EVR is legally required to comply with the requirements of this permit . Through the permit, compliance and enforcement actions can be used to make sure that the strategies proposed in EVR’s water quality plan are implemented.

Permit 107517 applies to all of EVR’s mines in the Elk Valley. It sets water quality limits for selenium, nitrate and sulphate at locations throughout the watershed.

These limits decrease over time to make sure water quality improves.

Types of limits in Permit 107517

Site performance objectives

Targets from the EVWQP were translated directly into Permit 107517 as Site Performance Objectives.

The objectives are based on scientific studies and their levels are set to protect local species and ecosystems. They help track if the overall goals of the plan are being met.

Site Performance Objectives need to be met at 7 locations throughout the watershed. The locations are called Order Stations.

Order Stations are in the environment where water from mines and rivers have mixed and the effects must be managed.

Compliance limits

The Site Performance Objectives informed the development of Compliance Limits using mathematical models.

The models predicted how much of each substance at the Order Stations came from each upstream mining operation. Limits were established for each substance for each mining operation using these predictions.

Compliance limits are used to regulate the amount of each substance released by a mine site. They show if management actions, such as water treatment, are working as intended. If limits are met, it’s expected to result in the Site Performance Objectives also being met at the Order Stations.

Compliance Limits apply at 7 Compliance Points downstream of the mine sites.

If any of these limits are exceeded, EVR must report to the ministry and enforcement actions may occur. Inspections by ministry staff are also used to verify achievement of the limits.

Key permit requirements

In Permit 107517, EVR must comply with over 200 pages of detailed legal requirements. This is in addition to the requirements of EVR’s other mine-specific authorizations and permits. Together, these legal requirements provide the most advanced and comprehensive regulatory regime in B.C. for managing waste.

Permit 107517 is regularly reviewed and updated based on new information.

Key requirements from the Elk Valley Water Quality Plan which are incorporated into Permit 107517:

Water quality limits

The 2014 EVWQP established short, medium and long-term water quality targets for:

Selenium
Nitrate
Sulphate
Cadmium
Calcite

The permit defines limits that are based on these targets.

EVR is legally required to meet water quality limits at 7 Order Stations and 7 Compliance Points.

Calcite is also regulated using Site Performance Objectives that apply to areas that are fish habitat.

Water quality planning

The 2014 Elk Valley Water Quality Plan included a water management and treatment strategy describing how EVR intended to meet the water quality targets.

This strategy was called the Initial Implementation Plan. Permit 107517 requires EVR to update this plan every 3 years to ensure the treatment strategy considers the latest science and treatment technology.

The most recent water treatment strategy was submitted in the summer of 2025.

Water quality modelling

Water quality planning is supported by the Regional Water Quality Model. The initial water quality model was developed in 2014 to support development of the Elk Valley Water Quality Plan.

The model describes:

How water interacts with mine sites (for example, rain or snow)
The processes that release substances from rocks
How the substances move into and through the environment

The model uses local monitoring data to ensure it represents conditions in the Elk Valley. It predicts how historic, current and future mining, including treatment, will affect water quality in the Elk Valley.

Consistent with water quality planning, Permit 107517 requires the model to be updated every 3 years based on the latest science and monitoring data.

Monitoring

Permit 107517 requires EVR to monitor:

Surface water quality
Surface water flow
Groundwater
Sediment
Aquatic life

The design, implementation and results of these programs are regularly reviewed by an Environmental Monitoring Committee to help ensure they meet the needs of the Province and First Nations.

Program results and committee recommendations provide valuable information on whether the permit and EVWQP are working and how to adapt to changing conditions and new information.

The Monitoring and Assessment section provides a detailed summary of monitoring in the Elk Valley and the Environmental Monitoring Committee.

Adaptive Management

The Elk Valley Water Quality Plan and Permit 107517 are intended to be responsive to new information. This is achieved through an Adaptive Management Plan. The plan requires EVR to continue investigating key topics related to understanding and managing water quality in the Elk Valley. It also creates a framework for identifying and responding to unexpected findings.

Permit 107517 requires EVR to implement the Adaptive Management Plan and to report on new information and adjustments by submitting:

An annual report that summarizes all current activities under the Adaptive Management Plan
An Adaptive Management Plan update that’s prepared every 3 years

Work conducted by EVR under the Adaptive Management Plan is reviewed by the Environmental Monitoring Committee.

Reporting

Permit 107517 requires EVR to submit reports to the B.C. government, including:

All water quality results submitted to the ministry’s Environmental Monitoring System database on a quarterly basis so the data is publicly available
Notification and reporting of any non-compliances with permit requirements
Quarterly and annual reports on permit-required monitoring results
Annual report summarizing all toxicity test results
Annual groundwater monitoring program report
Annual reports on results from all local monitoring programs
3-year comprehensive report on regional aquatic effects monitoring program results
