MINERALS
In 2007, Maryland ranked 33rd among the 50 states for total nonfuel raw mineral production value at $673 million and accounted for nearly 1 percent of the country's total production value. This was an increase of $10 million, up 1.5% from 2006. As per estimates of 2007, crushed stone represented the leading nonfuel commodity, followed by portland cement, and construction sand and gravel. These three mineral commodities accounted for approximately 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.
