BISMARCK, N.D. — When a pipeline rupture sent more than 20,000 barrels of crude spewing across a North Dakota wheat field, it took nearly two weeks for officials to tell the public about it.
The break in a Tesoro Corp. pipeline happened in a remote area, and officials say no water was contaminated or wildlife hurt. But environmentalists are skeptical and say it's an example of a boom industry operating too cozily with state regulators.
