Where fluorescent light fixtures could not be visually examined, the number of potential PCB-containing ballasts in fixtures was estimated based on the following assumptions: • Each single light tube fluorescent fixture contains one ballast. • Each multiple light tube fluorescent fixture contains one ballast for every pair of light tubes. • Each multiple light tube fluorescent light fixture contains one ballast for every pair of light tubes (four-foot length) and two ballasts for every pair of light tubes (eight feet or greater in length). • All light ballasts are assumed to contain PCBs unless the manufacturer's label indicates they are electronic ballasts. Mercury-containing light tubes were counted and documented in an inventory by length. Light tubes were determined to be four-foot tubes, and eight foot tubes.
