BISMARCK, N.D. (AP) — Teachers from four states are headed to North Dakota coal country.

The Lignite Energy Council says more than 120 elementary and secondary teachers from the Dakotas, Minnesota and Montana are slated to attend a seminar next week on how the coal known as lignite is mined and used to produce energy in the four-state region.

The Lignite Energy Council says it has been offering the seminar for 30 years. It includes a tour of a mine, power plant and the Great Plains Synfuels Plant near Beulah.

Teachers can get graduate credits for attending the seminar.
