Never doubt the ability of a small group of committed citizens to uncover government agency mistakes. Yesterday, a handful of Frisco residents met with EPA Region 6 staff about their local Superfund Site-in-progress known as the Exide lead smelter. The list of subjects to discuss was long and varied. Lead-paved streets, lead-lined creeks, lead contaminated waste water treatment plants, illegal landfilling of hazardous waste, modern pollution controls and the boundaries of the current two square-mile non-attainment area for lead in the middle of downtown Frisco. It was a productive meeting, with some new information coming to light, including the fact that those boundaries lines are not based on good science and need to be redrawn.
