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 Environment Protection Act 2019 replaced the Environmental Assessment Act 1982 on 28 June 2020. Proposals undergoing an assessment process at the time the new legislation commenced are required to transition into the new assessment system.

The NT EPA has prepared the following guidance material to inform proponents and other stakeholders about environmental impact assessment in the Northern Territory.
