Pollution Control Approvals
Understanding Consent to Establish and Consent to Operate
The two consents, the difference between them and the mistakes that delay both.
Promoters often treat CTE and CTO as one approval in two parts. They are sequential, serve different purposes and are assessed on different evidence.
Consent to Establish
Granted before the unit is set up, on the basis of what the promoter proposes to do and how pollution will be controlled. It is an approval of a plan: process, capacity, treatment and control measures, layout. It carries conditions that the unit must meet before it can seek the next consent.
Consent to Operate
Granted before the unit operates, on the basis that the measures described at the CTE stage are in place and working. It is an approval of a reality: the treatment plant is built, the control equipment is installed, the monitoring arrangements exist. It is valid for a period and renewed.
Common delays
A category assumed rather than checked; water and effluent figures that do not balance; treatment capacity below the stated effluent; layout changed after CTE without amendment; CTO applied for after trial runs have begun. Each of these is avoidable with a consistent application prepared alongside the project plan.
Not a substitute
Consent does not replace environmental clearance where the project category requires one, nor hazardous waste authorisation, nor groundwater permission. The full set of environmental permissions is identified for the specific project.
