And this was reported just yesterday:
Nearly 3M Gallons of Brine Spill; ND Oil Boom's Largest Leak
Nearly 3 million gallons of saltwater generated by oil drilling have leaked from a North Dakota pipeline, an official said Wednesday, the largest such spill since the state's current oil boom began and nearly three times worse than previous record spills. Two creeks have been affected, but the full environmental effect might not be clear for months.
Operator Summit Midstream Partners LLC detected the pipeline spill on Jan. 6, about 15 miles north of Williston and told health officials then. Officials say they weren't given a full account of the size until Tuesday
... The new spill is almost three times larger than one that fouled a portion of the Fort Berthold Indian Reservation in July. Another million-gallon saltwater spill in 2006, near Alexander, is still being cleaned up nearly a decade later.
...North Dakota has suffered scores of saltwater spills since the state's oil boom began in earnest in 2006.
A network of saltwater pipelines extends to hundreds of disposal wells in the western part of the state, where the briny water is pumped underground for permanent storage. Legislation to mandate flow meters and cutoff switches on saltwater pipelines was overwhelmingly rejected in the Legislature in 2013.
