The variances require each company to ensure effective operation of the treatment plant and carry out regular sampling and testing of the effluent as set out in their operations and monitoring plan.

The variance held by each company accepting their wastewater treatment equipment for use in temporary work camps does not replace the requirement to obtain a site specific private sewage permit.

The variance applies to work camps generating a maximum of 25 cubic metres per day of wastewater.
