Subject Re: Information Request - ExxonMobil MCU

Shareerah

In response to your recent e-mail, please find below the equipment and

emission information you requested concerning the MCU field operations

outside of the McElmo Creek Unit ("MCU") former gas processing plant. This

distinction is important, as the former gas processing plant and the field

operations at MCU are separate sources for purposes of the PSD, Title V and

Title III Clean Air Act programs. This is supported by the fact that the

currently applicable PSD permit applies to the former gas processing plant

only and does not apply to field operations, including tank batteries,

satellite locations and individual well locations that were in place prior

to the plant. In addition, it is important to note that Clean Air Act

Section 112(n)(4) clearly states that E & P equipment/operation emissions

cannot be aggregated to establish a "major source". Thus, the emissions

from these facilities should not be aggregated for purposes of determining

the applicability of the PSD, Title V or Title III programs at MCU.

Included in the spreadsheet below are the battery locations, emissions from

2000-2003 for all four batteries along with PTE calculations. Please note,

the Heaters at each battery are only used in the winter months. Tank

emissions were calculated using Vasquez-Beggs and Tanks 4.0. I will fax

over flow diagrams and gas analyses for each battery.

Please let me know if you have any questions.
