EPA released a guidance aimed mainly at old school buildings on the proper handling and disposal of PCB-containing fluorescent light ballasts and how to safely retrofit them to fully remove the hazard. EPA banned PCBs in 1979, but some PCB-containing ballasts were allowed to continue, provided they were not defective or leaking. For more information on handling and disposing of PCB-containing light ballasts, go to http://www.epa.gov/epawaste/hazard/tsd/pcbs/pubs/waste.htm.
