Background: Mercury is a global issue

Estimated 4400-7500 tons emitted worldwide from all sources – natural & man-made

Estimated 1/3 from natural sources; 2/3 from human activities

U.S. contribution is about 3%

Nationwide coal-fired utilities account for about 48 tons - about 1% of worldwide total mercury release

North Dakota utilities account for 1 ton, about 0.02% of worldwide total mercury release
