Purpose of environmental permissions

Your business must have an environmental permission from the Ministry of the Environment, Conservation and Parks if it:

  • releases contaminants into the air, land or water
  • stores, transports or disposes of waste

The purpose of environmental permissions is to set rules for these activities in a way that helps protect the natural environment and human health.

Types of environmental permissions

You or your business may require more than one type of environmental permission, depending on the nature of your activities.

Review the different types of environmental permissions to determine if you need to comply with the requirements – and find out how to apply or register:

Other requirements

Your activity may also be subject to requirements under other environmental legislation and services:

The law
