follow-up from NATA conversation


Hello Stephen  -  Were you the one who I had a conversation with about NATA? I checked with our risk staff for coke, Ted Palma, and he said that you have to look at tract level (see below from NATA page). I had downloaded at first the same thing that you had and saw the same 3.8 x 10-e5 MIR number in a county in KY. 

At the TRACK level for Allegheny County in PA, the risk from coke oven emissions estimated in the 2005 NATA (released in 2013) for one of the tracks (492700) is 300 MIR, with the coke oven emissions contribution 138 MIR or 48% of total 300 MIR for the track. The top pollutants contributing to 94% of the MIR in this track are from five HAP: coke oven emissions, PAH/POM, formaldehyde, napthalene, benzene in this order. The top two, coke oven emissions and PAH/POM, contribute 81% of the total MIR for the track. See attached table. If you look back on main county level data you will see that Allegheny County as a whole is the third highest county with COE, and has an MIR that is 25% of the KY County. 

P.s. David- Please forward to correct person if I have wrong guy. He was sitting a few people up from where I was standing and had a VERY well kept hair style, i.e. he was bald.
