DavidSorry that I didn't see those dimensions in the spreadsheet 

that you sent - I hadn't scrolled far enough to the right. 

The length of the roof vents is not too far off, but 

weren't exactly correct - Lines 1-3 are about 1050 feet 

long and line 5 is about 1000 feet long. I am searching 

for the width information, but I can't locate it this 

morning, and I know that you need to move forward on this. 

32 feet is not the right number - they should be something 

close to 10-12 feet wide. I'm working on getting you the 

correct data, and will send as soon as I have it. (should 

be this afternoon)

David, 

I'm not sure that I understand you correctly. Do you mean 

to say that everything looks good with the file that I sent 

on 12/18/13 or that everything looks good with the files 

you sent me earlier today except that those files 

incorrectly show a diameter for the roof vents? 

As far as the dimensions of the roof vents - the draft file 

I sent on 12/18/13 shows these roof vents as having widths 
p. 2 of 3 

of 32 feet and a lengths of 1086 feet. If these dimensions 

are incorrect then please let me know and I will make sure 

we get the correct dimensions in the file. 

Thanks,

Here are the files that I submitted previously. I did 

notice that the stack diameters for the roof vents are 

meaningless, since those don't have a "diameter". My 

understanding was that there is a different method employed 

in modeling those sources, and that a diameter was not 

needed. If you need dimensions (Length and width of the 

roof opening), please let me know, and I will get them to 

you. Other than that, everything looks correct. 

Dave

Attached, please find the revised kmz, ReleasePoint, and 

CategoryHAPs files for the Alcoa Inc. - Wenatchee Works 

facility (NEI42328). 

The kmz file includes both the emission points and the 

property boundary. 

We used the fugitive (area) source approach to represent 

the Potline Roof Vents and the Anode Bake Oven Roof Vents. 

Where we believe that the point should be deleted, the cell 

is shaded red. The cells not shaded in red matched MACT 

emissions sources and the coordinates were confirmed. 

Please contact me if you have any questions.
