Re: warning: EPA again closing down input on PVC dioxins

important.  If I were the VI and got the results in your dioxin sampling
program, I'd  *WANT* independent sampling to make my case airtight.

I'm corrected that yes, if incinerated, high dioxin content production
wastes will lower from the very high levels GP found.  But you got the
wrong paridgm here--incineration just rearranges Cl containing molecules,
and enough of it doesn't convert to HCl such that it becomes dangerously
bioavailable (including, to a lesser degree, in landfilled ash). I posit a
hypothesis that stack emissions would be in the range predicted by the
chlorine content, plus or minus burn conditions.  That's what I'd be
interested in comparing to VI's results and hopefully to sampling done by
an unconflicted party, representing typical operating conditions.

Not a good risk trade-off, incinerating high-chlorine feeds, in fact a
horrible one.  I'm sorry, a paid rep. isn't likely to admit that PVC is an
almost completly uneccessary and unrecyclable poison plastic.  Your
industry's workers are an amazing epidemeologic cohort, but the industry
doesn't regard them as human beings, judging by the Houston Chronicle's
reporting of the industry's decades long manipulation of their exposure &
health.  The industry is just rearranging deck chairs in its chlorine
dealings, and the toxicol. issue is substantially larger than dioxins, as
are the types highly toxic O-Cl's coming out your stacks more varied than
dioxin.
