BISMARCK, N.D. (AP) -- The U.S. Environmental Protection Agency has approved changes to North Dakota's water quality standards for the upper Sheyenne River.
Dave Glatt of the state Department of Health says the changes were part of a normal review of the standards and included a new sulfate limit for river. From the river's headwaters to just downstream of Baldhill Dam, the sulfate standard will now be 750 milligrams per liter, up from 450 milligrams.
A release from North Dakota's congressional delegation says the changes on the Sheyenne will increase operation of the west end outlet at Devils Lake and help efforts to reduce the water level.
