Jennifer, please you send me the 'Aggregate Calculations Report' of the May 21, 2004 GRI GLYCalc report that was submitted in the May 27, 2004 letter. Please let me know if this is a problem. Thanks.

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.
