The Department of Mines, Industry Regulation and Safety (DMIRS) ensures the responsible development of Western Australia's (WA) mineral, petroleum and geothermal resources. This includes regulating industry to ensure environmental compliance and implementation of best practice environmental management.
The department’s Resource and Environmental Compliance Division assesses mineral, petroleum and geothermal exploration and development applications within WA. The division also conducts environmental compliance audits and inspections to ensure approved activities comply with legislation, regulations, policies, and approval commitments and conditions. Unconditional Performance Bonds (UPB) may be imposed as mining securities for compliance with environmental conditions imposed under the Mining Act 1978.
The Resource and Environmental Compliance Division has an ISO 9001 certified quality management system and an Environmental Regulatory Strategy to ensure that resource industry activities are designed, operated, closed, decommissioned and rehabilitated in an ecologically sustainable manner, consistent with agreed environmental outcomes and end land uses without unacceptable liability to the State.
Environmental approvals for mining activities are granted in accordance with the Mining Act 1978 and include:
- Programme of work – submitted when a company or prospector wants to disturb the ground with mechanised equipment to explore or prospect for minerals.
- Mining proposals – submitted by a company for a proposed mining operation, or for a change to a mining operation. All mining proposals must include a mine closure plan.
- Mine closure plans – reviewed and re-submitted by a company with a mining proposal and covering all aspects of mine decommissioning and rehabilitation.
Environmental approvals for petroleum and/or geothermal activities are granted in accordance with the Petroleum and Geothermal Energy Resources (Environment) Regulations 2012, the Petroleum Pipelines (Environment) Regulations 2012, and/or the Petroleum (Submerged Lands) (Environment) Regulations 2012 and include:
- Environment plans – submitted by a company for proposed petroleum and/or geothermal activities (including wells, facilities, pipelines and surveys).
- Oil spill contingency plans – submitted by a company as part of an environment plan outlining the emergency response structure, strategy, and arrangements in the event of a spill incident.
In conjunction with the above approvals, a native vegetation clearing permit may be required. These may be granted by DMIRS under delegation from the Department of Water and Environmental Regulation in accordance with the provisions of the Environmental Protection Act 1986 and the Environmental Protection (Clearing of Native Vegetation) Regulations 2004.
