Rowley was created in 1970[1] as the site of a large magnesium processing plant. The location was named after Jeff Rowley who was the CEO of National Lead Industries during the construction of the plant.[2] In the mid-70s, National Lead Industries changed its name to NL Industries and in 1980 sold the plant to AMAX.[2] In 1989, the facility was sold to the Renco Group, and the facility renamed Magnesium Corporation of America aka Magcorp.[2]
This facility was identified by the EPA as a major air polluter in the 1990s[3] and has been identified as a significant emitter of chlorine and bromine in the atmosphere.[4][5][6] In 2001, Magcorp went bankrupt and the Renco group purchased the assets and formed US Magnesium.[2] In 2005, the facility was investigated by the CDC for worker health hazards.[7]
In 2006, Allegheny Technologies announced plans to build a titanium smelter at Rowley, budgeted at $325 million.[8] The smelter was built adjacent to the US Magnesium plant.[9] The plant came online in 2012 and cost $460 million.[10] By September 2016, the smelter was idled because the metal could be procured on the market at a cost lower than the production cost at ATI.[11]
