The amount of recycled fuel oil (RFO) used by Corus has reduced significantly in the last two years due to a combination of contractual and operational issues. Between 5 December 2008 and 25 August 2009, no RFO was used on the blast furnace and use ceased again on 12 January 2010 in preparation for mothballing of the blast furnace. The peak usage of RFO was approximately 150,000 tons in 2006 and 2007. This fell to about 16,000 tons in 2009.
The Environment Agency's pollution prevention and control (PPC) compliance team on Teesside which regulates the Corus facility is not aware of any incident involving the illegal disposal of RFO resulting from this reduction in use by Corus. If there is any evidence of such an incident the Environment Agency will investigate it fully.
