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.
