North Dakota, Washington state at odds over oil train rules

BISMARCK, N.D. (AP) — North Dakota officials are pressuring Washington’s governor to veto legislation requiring oil shipped by rail to have more of its volatile gases removed.
The bill awaiting Gov. Jay Inslee’s signature requires a lower vapor pressure limit for crude shipped by rail than either North Dakota requirements or industry standards.
Proponents say it will boost safety. North Dakota officials worry it could hamper the nation’s No. 2 oil producer.
