The Facility, formerly operating under the names Laporte Pigments, Mineral Pigments, and Rockwood Pigments operated a pigment manufacturing facility, located approximately two miles north of Beltsville, Maryland.

Rockwood Holdings was acquired in its entirety by Albemarle Corporation on January 13, 2015, and Albemarle is now 100% owner of the subsidiary Excalibur Realty. The site owner continues to be Excalibur Realty Company, a wholly owned subsidiary of Rockwood Holdings ("Rockwood"). Huntsman Pigments Americas LLC ("Huntsman") is the lessee of the site and has manufacturing operations there.

The site is bordered to the west by US Route 1 and the Chessie Railroad tracks; to the east by Conway Road; to the north by Muirkirk Road, and to the south by a light industrial park. Records indicate that the site has been used for industrial purposes since at least the 1940s. The earliest file records mentioning Mineral Pigments, however, date to 1972. The facility activities include the manufacturing of zinc phosphate and the milling and blending of iron oxides. Shallow groundwater at the site has been investigated since 1985 under MDE supervision. Two source areas were removed under MDE supervision in the 1980s and 1990s.
