Foot Notes

1. Columns J and K - Start and End Dates - These columns were not updated because we do not have a description of the meaning of these values.

If this information is needed, please provide a description or explanation of the information needed.

2. Column S - Emissions TPY - This column lists the 2007 actual emissions as reported in this unit's annual emission inventory to the LDEQ. Of the last

years, 2007 is the closest to "normal" production. Because the economy 2008 and 2009 were low production years.

3. Column T - Max hourly emissions - This column slits the permitted maximum pounds per hour for each source.

4. Columns U thru X - Start up and Shut down emissions - Emissions from this facility, because of the way it is operated, are not significantly different

during Start up and shutdown from normal operations. The pounds per hour shown a SU and SD are the permitted average pounds per hour

for each source.

5. Columns AO and AP - Exit gas flow and velocity. A value of nil was provided when the flow and/or velocity are too small to be sampled or calculated.

6. Column AV - Emission Performance Level Code. This column was not updated because we do not have a description of the meaning of this value.

If this information is needed, please provide a description or explanation of the information needed.

7. Source 1700-20 is equipped with a condenser that is 95% efficient on removing chloroprene. Because the small amount of toluene present in the

stream, this condenser is not efficient in removing toluene, therefore, was not listed as a toluene control device.

8. Sources 1700-64 and 1700-66 - These are fans located on the side of the building which vent horizontally.

9. Source 1700-79 - does not fit on any of the SPCC Codes given.
