Whether it’s because of the spike in gas prices, the recent chip shortage, or growing enthusiasm for alternative energy use, Congress is considering legislation that would update a 150-year-old mining law.

The bill, known as the Clean Energy Minerals Reform Act, was introduced by Democratic Congressman Raúl Grijalva of Arizona. Among other things, it would strengthen environmental standards and force mining companies to pay royalties for operations taking place on federal lands.
