5. Emission Reductions in the A pril, 1981. CTG Were<br />
Overstated I.7<br />
This comment is no longer applicable since projections<br />
<strong>of</strong> industry emissions have been removed <strong>from</strong> this<br />
draft <strong>of</strong> the CTG,<br />
B. . Processes Covered by the CTG,<br />
---. ...<br />
The. Phfllips particle form (slurry) process is used by the<br />
EPA for their highdensity polyethylene model plant. It<br />
is intended Oto represent all other liquid-phase processes<br />
with high-efficiency catalyst that do not require catalyst<br />
removal.c But DQW, Du Pont, and perhaps others use solutior<br />
liquid-phase processes that are completely different <strong>from</strong><br />
the Phillips process, the'emissions arc different, and they<br />
Come out at different places. We presume these are not<br />
cover& by this CEG since the EPA has made no evaluaGn<br />
<strong>of</strong> appropriate control tehcnology or abatement costs for<br />
them.<br />
