The
Riverbend permit allows Duke Power to burn
mineral oil containing polychlorinated biphenyls
(PCB). The Title V permit states that total PCB
content shall not exceed 500 ppm and that,
"Total maximum boiler injection rate shall
not exceed 10 percent of the total fuel feed
rate." Mineral oil may be burned at one unit
at a time. At Riverbend, Duke claculates the
potential fuel use at 229,094,604 gallons of fuel
oil.
