The Forest City air monitoring station lies near a secondary lead smelter owned by Exide Technologies. Since the mid-1970s, employees at the Cannon Hollow Plant have extracted lead from lead batteries to refine it and make it reusable. The state-operated monitor helps determine exposure to airborne lead from the smelter for a segment of the population.
From 1996 to 2000, the site was known as Schuylkill Metals-West, or the levee site. The EPA ID was the same as today's Forest City site. Monitoring ceased in 2000. The department reactivated the monitor in response to EPA monitoring regulations, 2008-2010.
Pollutants
Lead
Since 2008, the primary and secondary ambient air standards for lead have remained at 0.15 micrograms per cubic meter (μg/m3). The primary standard reflects EPA's concern for public health, while the second standard demonstrates concern for public welfare. EPA bases the standard on the highest rolling three-month average over a period of three years and two months. A monitoring site meets the standard when the lead concentration is less than or equal to 0.15 μg/m3 averaged over three months. The standard is not met if the concentration exceeds that level once or more within a three-year period.
