Environmental Impact Assessment


Aventus prepares Environmental Impact Assessment (EIA) documents using this industry knowledge and experience to guide clients

through the regulatory minefield.


EIA is undertaken at the Commonwealth and State/Territory level. Under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), administered by the Department of the Environment (DoE), the following approvals documentation is required (in increasing level of detail, dependent on the complexity of the project and its impacts):


• Referral.

• Preliminary Documentation.

• Public Environment Report (PER).

• Environmental Impact Statement (EIS).


Under the Commonwealth Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and associated environment regulations, administered by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA), the following types of EIA for offshore petroleum activities are required:


• Environment Plan (EP).

• Offshore Project Proposal (OPP) (for large-scale offshore developments).


Mirror offshore legislation in the states and Northern Territory (NT) also requires an EP for activities in coastal waters to be approved by the Administering Authority. For the onshore State and NT jurisdictions, an EIA in its various guises is required.


EIA involves the following:


• Risk assessment.

• Approvals, schedule and resource planning.

• Regulator liaison.

• Stakeholder consultation.

• Specialist consultant field studies and modelling.

• Desktop research.

• Development of project mitigation controls as an iterative process between proponent and stakeholders.

• Report writing.
