General guidance

• Conceptual Site Model (CSM) Guidance (PDF, 1MB)
  • A Conceptual Site Model is an optional approach to support the Environmental Management Act (EMA) effluent permitting applications. A CSM is an approach that could enable the proponent to convey existing information requirements in a format that may be more easily understood by a range of stakeholders, including Indigenous groups and the public. A CSM does not replace other requirements under the EMA or its regulations, application process, the use of an Information Requirement Table or Technical Assessment Report
• Fugitive Dust Management Plans Guidance (PDF, 768KB)
  • Guidance for the development of fugitive dust management plans
• Joint Application Information Requirements (JAIR) Guidance (PDF, 934KB)
  • ​​Sets out the information that's required to support a joint application for a Mines Act permit and an effluent discharge permit under EMA issued by the B.C. government. It's intended for both new and existing major mines, including major expansions. The combined technical information requirements are intended to reduce overlap in the information required by the ministries responsible and enable one application, or bundled applications, to be submitted for review
  • Joint Application Information Requirements (JAIR) Table (PDF, 776KB)
    • Accompanies Information Requirements Table to support the Joint Application Information Requirements. Refer to the Joint Application Information Requirements and all other reference material and guidance in reviewing the Information Requirements Table. This table will be used in the pre-application discussions to help document the information requirements to support a Joint Mines Act and Environmental Management Act application
• Metal leaching and acid rock drainage (ML/ARD) guidance and policy

• Guidance to Preparing Effective Plans for Environmental Management Act Permits (PDF, 302KB)
  • Recommends best practices and serves as a general reference for Qualified Professionals who are responsible for preparing management plans in response to regulatory requirements. Provides advice on the types of language to include in a plan to ensure that when it's implemented, the actions stipulated are clear and effective
• Effluent Permitting Process Guidance (PDF, 514KB)
  • This guidance reflects the current direction of the ministry on the effluent permitting process for mining projects. The guidance addresses mine-related effluent discharges only. For other waste discharges related to mine activities, such as air emissions, solid waste or hazardous waste disposal, separate process steps may be required. For further details on Step 3 of the effluent permitting process, refer to the Mining Best Achievable Technology (BAT) Assessment Methodology (PDF, 578KB).
• Guidelines for Groundwater Modelling to Assess Impacts of Proposed Natural Resource Development Activities (PDF, 35MB)
  • Guidance to industry and government agencies on how to develop, use, and review groundwater models used to assess environmental impacts due to mining and large groundwater extraction projects. These guidelines provide general guidance based on acceptable ‘best practices’ for the development and use of groundwater models by resource industry groundwater professionals and a review of groundwater models by regulators.

Technical guidance

• Technical Guidance 1: Environmental Impact Assessment and Technical Assessment Terms of Reference (PDF, 859KB)
  • These Terms of Reference are intended for proponents of major mine projects applying for an effluent discharge permit under the EMA. This document outlines the information requirements of the Technical Assessment Report (TAR), with particular emphasis on the Environmental Impact Assessment (EIA) normally required as part of the application
• Technical Guidance 2: Information Requirements Concordance Table (XLS, 12.9KB)

  • The Information Requirements Concordance Table is intended to assist proponents and the ministry in identifying the information needed to support an application for an Environmental Management Act (EMA) effluent permit. It is based on the Joint Application Information Requirements (JAIR) Table (Word, 5.91MB), which is used for joint EMA/Mines Act applications.

    Applicants should use the concordance table to determine which sections of the JAIR Table typically apply to an EMA-only effluent application. Once the scope is confirmed with the ministry, an abbreviated version of the JAIR Table will be used to screen applications and assess whether the required information has been adequately addressed in the Technical Assessment Report (TAR) and Environmental Impact Assessment (EIA).

    For joint EMA/Mines Act applications, refer to the Joint Application Information Requirements (JAIR) Guidance Document(PDF, 929KB)

• Technical Guidance 4: Annual Reporting Under the Environmental Management Act (PDF, 2MB)
  • This guidance document summarizes the expectations for annual reports submitted by mining companies operating in B.C. It also recommends a reporting format that makes it easy for the reader to recognize both compliance issues and environmental concerns. Sections 3, 4, and 5 can be used as a guide for developing the table of contents in an annual report. Annual reports submitted from 2015 onward should follow this document. This guidance does not replace or alter the legal requirements of any permit, approval or regulation issued under provisions of the EMA

Information requirements for geology/geochemistry, meteorology and air quality, surficial hydrology, hydrogeology, water quality (physical and chemical parameters, aquatic sediments, tissue residues, and aquatic life), fish and fish habitat and initial environmental impact assessment are covered, focusing on the collection, analysis, interpretation and submission of baseline information as part of a proposal to develop a mining project in B.C. By providing these requirements early in the project evaluation stage, the province's goal is to ensure effective study design, information collection and data usage/interpretation that will assist in both the initial project evaluation and throughout the development, operation and closure of a mine
