In a petition filed with the Pipeline and Hazardous Materials Safety Administration, AG Eric Schneiderman sought
reduced limits on the
vapor pressure of
oil shipped in tanker cars from the Bakken hydrofrack fields of North Dakota to coastal refineries.
In the order, well operators who did not
reduce vapor pressure using environmental conditions (heat and pressure limits within the separator units) are required to conduct testing using ASTM D6377 [Standard Test Method for Determination of Vapor Pressure of Crude Oil: VPCRx (Expansion Method)-
