PIERRE, S.D. (AP) - The South Dakota Department of Environment has launched a website that provides information on mine sites for sand, gravel and aggregate materials used in construction.
The site features an interactive map showing information for about 519 construction aggregate licenses the department has issued to mine nearly 21,000 acres at 1,638 pits.
The website also has information on nearly 4,600 active and inactive sites that have been licensed since 1983.
The interactive map covers sand and gravel mine sites. It also includes mine sites for rock to be crushed and used in construction, pegmatite minerals, limestone, iron ore, gypsum, shale, pozzolan and other materials used to make cement or lime.
