The Senate,  has asked the Nigerian National Petroleum Company Limited and its subsidiaries to submit relevant documents on the Turnaround Maintenance projects of the Nigerian refineries.

The Senate ad hoc committee investigating the various Turnaround Maintenance projects of Nigerian Refineries gave the directive during an interactive session with NNPCL management and other executives of the oil sector.

It noted that it had records of over $592,000 000 spent between 2010 to date on TAM, yet none of the refineries was working.
