Last week's 33rd anniversary of the Surface Mining Reclamation and Control Act, also known as SMCRA, marked an important milestone in the development of the Powder River Basin coal fields, as does November's upcoming 20th anniversary of the 1990 Clean Air Act Amendments, which mandated reductions in sulfur emissions.
More often overlooked in the development of the region, which now annually accounts for about 40% of US coal production, is the construction of the so-called Joint Line, a 100-mile stretch of railroad in northeastern Wyoming used by Union Pacific and BNSF Railway that serves the six largest coal mines in the country.
