Subject: Retention for shop towels...

Hi Deb...

Wisconsin Department of Natural Resources just finalized guidelines for
determining emissions from lithographic printing facilities. I can send
you a copy if you would like.

The guidelines are for cature efficiencies for heatset web offset presses
and inclued ink VOC capture efficiency, automatic blanket wash VOC
capture efficiency, fountain solution VOC capture efficiency, ink VOC
retention factors on paper substrate and retention factors for cleanup
solvent on shop towels.

Retention factors for cleanup solvent on shop towels are:

1) 50%-provided all of the following conditions are met:

    A) VOC composite vapor pressure is 10 mm Hg @ 68 degrees F or less,
        or the cleanup solvent contains less than 30% by weight VOC;

    B) Shop towels are handled properly, laundered, incinerated, or
        disposed of following all appropriate regulations; and

    C) Soiled towels are kept in closed containers both on site and
        during transport off site.

2) 40%-provided all of the following conditions are met:

    A) VOC composite vapor pressure is greater than 10 mm Hg but less
        than 25 mm Hg @ 68 degrees F or the cleanup solvent contains
        more than 30% by weight VOC;

    B) Shop towels are handled properly, laundered, incinerated, or
        disposed of following all appropriate regulations; and

    C) Soiled towels are kept in closed containers both on site and
        during transport off site

3) 0%-if neither of the above conditions are met
