The 150-year-old McConway & Torley steel foundry is the ninth-most toxic active air polluter in Allegheny County (originally eleventh-most toxic, this facility moved up the list with the closure of the Koppers Inc. Clairton Tar Plant in late 2016). Located in Lawrenceville, one of the most densely populated neighborhoods in Pittsburgh, this plant poses a public health risk to the 147,700 people who live within three miles of it. A draft Clean Air Act permit for the plant was issued for public comment in the fall of 2017, though a final version has not been released.
The facility is less than a mile from Arsenal Middle School and has been the subject of community complaints and official enforcement efforts for many years. Between April 2011 and April 2014, air monitors around the facility recorded average manganese levels that were 50 percent higher than EPA limits.
After years of complaints from residents, pressure from environmental advocates, and legal challenges, the Allegheny County Health Department forced the facility to install better pollution control technology. The upgrades have dramatically lowered toxic emissions, especially of manganese.
