PRODUCTION


In 2006, Maryland ranked 33rd among the 50 states for total nonfuel raw mineral production value at $653 million and accounted for nearly 1 percent of the country's total production value. This was an increase of $73 million, up 12.6% from 2005. As per estimates of 2006, crushed stone represented the leading nonfuel commodity, followed by portland cement, and construction sand and gravel. These three mineral commodities accounted for more than 99% of the State's total value.

Within the Department of the Environment, the Mining Program of the Water Management Administration oversees mining and mineral production in Maryland.
