The Attorney General of New York submitted a petition for rulemaking to The Pipeline and Hazardous Materials Safety Administration requesting implementation of a Reid Vapor Pressure limit less than 9 pounds psi for crude oil transported by rail.
PHMSA is currently seeking comments on a range of vapor pressure thresholds and will evaluate the potential safety benefits of vapor pressure thresholds in regards to the hazardous materials classification process for both unrefined petroleum based products and Class 3 material liquids.
Interested parties will be able to submit comments, data, or relevant information between December 30, 2016 and February 28, 2017.
