To protect public health in the neighborhoods surrounding the Dennis Collins Park site during its chromium cleanups, PPG implemented a dust-control program.

Airborne concentrations of hexavalent chromium during the cleanups were less than the limit permitted by the New Jersey Department of Environmental Protection.

That’s according to final air-monitoring reports dated 2016 and 2020-2021 on the effectiveness of the dust-suppression plan, which is based on the results from air monitors that operated on the fence line of the site.

Among the exposure-prevention measures were:

• Water misting work areas to suppress dust;
• Restricting open-air soil stockpiles;
• Spraying surfaces with dust-suppression materials;
• Limiting truck traffic to paved areas on-site;
• Pressure-washing trucks in protected areas before exiting sites; and
• Covering open excavations when not being worked.
