This is based upon a UNC Modification (0710 – CDSP provision of Class 1 read service) obligating the CDSP to take on Class 1 read provision on behalf of Shippers. The Modification was raised as the industry felt it appropriate for the provision of the service to be managed centrally and on behalf of Shippers which gives Shippers more control over this service. Although moving to CDSP provision does not provide each Shipper individual control, it allows Shippers to collectively define the service.


The charges for Daily Metered (DM) assets and DM read charges will be removed from Transporter Metering Charging statements and will no longer be included in the invoices sent by the CDSP on behalf of Transporters. They will be replaced by DSC charges.


This Change Proposal has been raised to put in place the processes and make the required changes to deliver what is set out within Modification 0710.
