SUBSCRIBER NOTE: Platts to assess USGC premium conventional at 13.5 RVP through Feb 18

Platts will assess premium conventional US Gulf Coast gasoline at 13.5 RVP effective February 13 through February 18, based on a change announced Friday by Colonial Pipeline.

This subscriber note supersedes an earlier note about the change from 13.5 RVP to 11.5 RVP. Platts had begun assessing premium conventional at 11.5 RVP on Thursday.

"This change helps alleviate transition concerns expressed by our customers, helps maintain minimum batch volumes and is more reflective of our past transition timing," Colonial said in a notice to shippers.

The last day of assessments at 13.5 RVP will be Thursday, February 18.
