Environmental impact assessment

Environmental impact assessment allows the NT EPA to analyse the significant potential environmental impacts of a development proposal, and make recommendations to the Minister about the acceptability, or otherwise, of those potential environmental impacts.

Environmental impact assessment is only required if the NT EPA decides that the proposal has the potential to have a significant impact on the environment.

The process for environmental impact assessment is legislated under the Environment Protection Act 2019 and Environment Protection Regulations 2020. The environmental impact assessment process is described in this guide PDF (811.5 KB) and this flowchart PDF (771.2 KB).

The Environment Protection Act 2019 replaced the Environmental Assessment Act 1982 on 28 June 2020. The NT EPA has prepared a policy to assist proponents that are required to transition into the new assessment system.

The NT EPA has prepared guidance material for proponents and other stakeholders participating in an environmental impact assessment process.

Referring a proposal to the NT EPA

If you are the proponent of a development proposal, you are legally required to refer your proposal to the NT EPA, if the proposal may have a significant impact on the environment.

The NT EPA has prepared guidance to assist proponents PDF (505.5 KB) to understand when a referral is required; the information that must be submitted in the referral; and how the NT EPA will make a decision about whether the proposal has the potential to have a significant impact or not.

New proponents are encouraged to contact the Environmental Assessment Unit early, to discuss whether their proposal requires referral to the NT EPA. Contact can be made by:

Public consultation

The community is afforded the opportunity to make written comments on proposals at various stages of the environmental impact assessment process.

To assist members of the community to make a submission; and understand how the NT EPA takes public comments into account; the NT EPA has prepared guidance for preparing a submission PDF (254.3 KB).

Proposals that are undergoing environmental impact assessment are listed on the NT EPA’s consultation hub. The hub provides information about opportunities for public comment for each proposal.
