Why pollution consent matters

Industries and many businesses that can affect the environment need consent from the State Pollution Control Board to set up and run. This consent ensures your unit manages emissions, effluents and waste responsibly. Operating without it can lead to penalties and closure.

CTE and CTO: two stages

There are two key consents, taken at different stages:

  • Consent to Establish (CTE) — obtained before setting up the unit
  • Consent to Operate (CTO) — obtained before starting operations

You generally need the CTE first, and then the CTO once the unit is built and ready to run.

Pollution categories

Units are classified by their pollution potential — commonly into categories such as red, orange, green and white, from higher to lower impact. Your category affects the requirements, conditions and validity of your consent. Knowing your category early helps you plan.

Documents and details commonly required

  • Business and site details
  • Description of the manufacturing or business process
  • Details of emissions, effluents and waste handling
  • Layout plans and machinery details
  • Identity and registration documents

Staying compliant

Consents come with conditions and validity periods, and must be renewed. Units are expected to maintain pollution control measures on an ongoing basis. Treating environmental compliance seriously protects both your business and the community.
