South Coast Air Quality Management District has positioned monitors near Anaplex and Aerocraft Heat Treating, two firms identified by SCAQMD as sources of elevated hexavalent chromium levels. How long will those monitors remain in place to monitor those businesses?

SCAQMD has indicated that those monitors will remain in place throughout the enforcement period associated with the abatement orders that have been entered into by Anaplex and Aerocraft heat Treating. This is likely to be between one to two years.

Based upon additional scientific evidence and business conditions at the time that SCAQMD concludes that ongoing monitoring is no longer required to enforce their abatement order, the City of Paramount may step in as needed to sustain the monitoring in these areas to provide additional public confidence and oversight on air quality concerns in this area of the city.
