Cortney, Nancy:

Here is some additional info you requested on primary lead. The spreadsheet 

shows the overlaps of the maximum impacts for each of the 4 major emissions 

points (the raw data sheet shows the monthly concentration estimates for each 

emission point that went into calculating the max 3-month rolling average). 

Based on our re-examination of this information, we note that the furnace and 

the refinery max impacts coincide, meaning that their respective emissions 

caps need to reflect that. As a result, we have re-calculated the caps for 

those 2 emission points and they are lower. The others show very little 

overlap as originally stated, with the max main stack impact occurring about a 

kilometer from the stack. We will need to edit the preamble and risk report 

to reflect this.

Subject: Information on overlapping lead sources and Main Stack

 emissions for OMB

Attached below is the file looking at the contributions of each source at the

site of maximum lead concentration resulting from the main stack,

refinery stack, furnace stack, and fugitives. Based on this

information we calculated new caps of 0.55 for the refinery and 0.36 for the 

furnace

Also, for the main stack the max concentration is 0.0007 ugs/m3. It

occurs at census block 290997007002007, with latitude 38.25947 and longitude -

90.38779. That is about 1000 m away from the main stack.
