Scott,

At long last, attached are the final PDF version of the 1-hour SO2 modeling report, using AERMOD, for 

the McElmo Creek Gas Plant and the transmittal letter. Per your instructions below, two hard copies of 

the report, with one report containing a modeling DVD, has been sent by FedEx to Andrew Chew with 

delivery scheduled for approximately 10:30 AM PDT on Friday, June 3.

The modeling files are rather large and not readily amenable to sending by e-mail. However, the DVD 

accompanying the hard copies of the report contain pertinent AERMAP, meteorological and AERMOD 

input/output files.

Please contact me if you have any questions.

Tom -

Andrew Chew confirmed that we would like two paper copies of modeling report in addition to electronic 

one. A single copy of modeling file DVD is enough. (If there is some subset of the DVD that is small 

enough that it makes sense to send electronically in addition , then please do that, too.)

I think best place to send paper / DVD would be to Andrew:

Subject: 1-Hour SO2 Modeling Report for McElmo Creek Gas Plant

Scott,

 

We have completed our modeling analyses for estimating 1-hour SO2 impacts from the flare at the 

McElmo Creek Gas Plant with modeled background sources. We will be finalizing the modeling report 

and have ready for submittal next week. We have the following questions pertaining to submittal of the 

report and modeling files to you.
 

1. Do you want both electronic and paper copies of the air modeling report or is an e-mailed electronic 

copy (in PDF) sufficient?

 

2. If you want a paper copy submittal, how many copies?

 

3. Do you want DVDs of the modeling files or do you prefer electronic copies only?

 

4. How many copies of the modeling DVD would you need?

 

The modeling files submittal will include a readme file to explain the modeling files content, all model input 

and output files, pre-processed meteorological data as received from the UDAQ and AERMAP 

input/output files.

 

We look forward to your response.

 

Thanks,
