3. Recap of Previous Meeting
Never, ever touch the Mod 640 invoice
Timelines for Mod 640 Invoices already tight
Any correction could be through ad hoc invoice issued at same time as Mod 640 invoice
Split view on Governance
Could be under UNC – aids billing, transparency and compliance/interpretation
Could be outside of UNC similar to ISD process – facilitate Shipper to Shipper settlement, simpler?
Need to address materiality of issue
