North Dakota officials are pressuring the state of Washington to back off from legislation requiring oil shipped by rail to have more of its volatile gases removed. Proponents of the bill awaiting Gov. Jay Inslee's signature say it will boost safety, but North Dakota officials worry it could hamper the nation's No. 2 oil producer. North Dakota's three members of Congress have asked Inslee to veto the bill. North Dakota regulators are considering a lawsuit.

In this July 5, 2018, file photo, eroded hills are shown in Theodore Roosevelt National Park in western North Dakota. Attorneys for North Dakota's Health Department say the agency didn't improperly discount its own concerns about a proposed oil refinery near the park when it permitted the project earlier this year. The department and developer Meridian Energy Group want a state judge to reject a challenge by environmental groups to an air quality permit that allowed the company to begin construction last summer at the Davis Refinery site about 3 miles from the park.

The company says the refinery will be built with modern technology and will be the 'the cleanest refinery on the planet.'

Opponents of an oil refinery planned near Theodore Roosevelt National Park in North Dakota are imploring state regulators to give them a chance to explore whether the developer is being truthful about the project's size.

Opponents of Refinery Question Developer

Meridian says the site will have a capacity of 49,500 barrels per day — which is just below the 50,000-barrel threshold that triggers a state review.
