Proposal description:

The proposal is for the installation and operation of a Heated Overland Thermal Treatment (‘Hottpad’) system at the Karratha liquid waste treatment plant and waste transfer station located approximately 6 kilometres south-west of Karratha.

The Hottpad is intended to treat hydrocarbon-impacted ‘sludge’ from oil and gas operations in the region, that are currently transported interstate for thermal treatment.  The proposal has a project life of 10 years and involves a self-sustaining smouldering combustion process to thermally degrade hydrocarbon contaminants.

The system comprises: 

Two containerised Hottpad units 
An exhaust management system, including a mercury recovery unit, odour control and stack 
Continuous emissions monitoring system
