Re: PCBs burned in the South make their way up to the Great

  These figures are all very nice, but not very
  meaningful. It is well known that
  the dump stack, which prevents rotary kiln incinerators
  from exploding when
  there is too much internal pressure, is UNMONITORED
  and gets
  used FREQUENTLY during real burns of hazwaste.
  Note the case of Jacksonville, AR, in which a
  increased (measurably) the dioxin in people's blood
  the area
  by 22%. The combustion efficiency of this incinerator,
  it was proven
  by Pat Costner of Greenpeace, actually had a burn
  efficiency of
  99.96 percent, increasing amount of dioxins, etc. by
  of 400.
  The EPA admitted in court that they COULD NOT PRODUCE
  DESTRUCTIVE EFFICIENCY OF 99.9999%. On the basis of
  this admission,
  the Jacksonville incinerator was shut by court order.
  One of the major reasons they cannot produce that
  is because of
  the dump stack...
  Hazwaste incineration is a BAD IDEA and anyone living
  near one
  or who might have one moving in should seriously
  opposing and closing it.

  The math is off in this statement concerning PCB
  burning theoretical
  circulated on dioxin-l from a Houston web site
  Why would burning PCB waste with 1 PPM PCB release at
  theoretical DRE release more PCB than burning the
  amount of PCB waste
  at the same DRE if the waste had 750,000 ppm or
  500,000 ppm PCBs
  for theoretical undestroyed PCBs?
  500,000,000 pounds =  5  E8 pounds of waste
  99.9999% DRE is equivolent to  0.0001% PCB undestroyed/
  0.0001% PCB undestroy/released =  1 E-6 proportion of
  PCB release during burning
  1 ppm PCB content = 1E-6 proportion of PCB in a waste
  which is 1 PPM PCB
  Therefore, for your  1 PPM PCB waste:
  In 500,000,000 pounds of  1 PPM PCB waste
  there is    5 E8  * 1 E-6 total PCBs
  or 500 pounds of PCBs in the waste to be burned.
  If these 500 pounds of PCBs are burned with a DRE of
  99.9999% then after
  incineration there is     5 E 2   *  1 E-6 or  5 E -4
  undestroyed or
  0.0005 pounds of PCB emitted/undestroyed at  99.9999%
  theoretical DRE
  For your 500,000 ppm PCB waste:
  In 500,000,000 pounds of 500,000 ppm PCB waste
  there is  5 E8  *  5 E 5  * 1 E-6 total PCBs
  or 25 E7 pounds or  250,000,000 pounds of PCB
  If these 250,000,000 pounds of PCB are burned with a
  DRE of 99.9999% then
  after incineration there is  2.5 E7 * 1 E-6  or   
  E 1    or
  25 pounds of PCBs emitted/undestroyed at 99.9999% DRE
  The above are theoretical emission rates and do not
  with PICs, PCDD/F, HCL, etc.
