In Allegheny County, the Allegheny County Health Department decides these permits. Join GASP, PennEnvironment, Clean Air Council, Clean Water Action, Environmental Integrity Project, SWPA Grassroots Air Quality Town Hall activists and the Breathe Project in the effort to reduce pollution greenhouse gases.
