I would not delete those records as the units are not completely
captured by the HVLC system (i.e. SSM).  Thanks!

Thanks for responding.  We have made the revisions to SN76 (Black
Liquor Storage Basin) as suggested, but have some additional questions
about SN61 (Line 2 Decker).  The ICR response for GP-Crossett indicates
that the Line 2 Decker is vented to the HVLC system, which suggests that
the Line 2 Decker emissions in the NEI emissions file may already be
accounted for in the NEI emissions for the thermal oxidizer that
incinerates the HVLC vent gases.  The same goes for the brown stock
washer emissions and digester emissions in the NEI emissions file. 
They also appear to be collected in a vent gas collection system and
sent to the thermal oxidizer.  Should we remove the records for the
deckers, brown stock washers, and digesters if they are already
accounted for elsewhere, in order to avoid any double-counting of
emissions for this facility?

Thanks.
