Subject: RE: Incompleteness Determination Letter

- Anadarko Discoverer Spirit EGOM Permit Application

Hello Eva,

Please find Anadarko's response in the attached docu ment regarding the remaining portion of comment

#2 in the incompleteness determination letter (dated February 27, 2013) for Discoverer Spirit EGOM

permit application. This submission completes Anadarko's response for all questions and comments

except for c omment no. 6.

Regarding comment no. 6, Anadarko determined that the welding operations will be performed as a part

of maintenance activities. The proposed welding operations will result in minimal increase in short term

and long term emissions of PM, PM 1 0 , PM 2.5 , and HAPs. Moreover, Anadarko would like to add Vertical

Seismic Profile (VSP) engines as additional sources of air pollution and increase operational flexibility of

certain air pollution sources by increasing currently requested operating time. Due to these proposed

changes, the revised total Potential to Emit of a few pollutants (e.g., PM 10 ) will be greater than the

emission rates used for performing air dispersion modeling analysis for respective pollutants. Hence,

Anadarko will submit a permi t application addendum including emission calculations for requested

changes, revised air dispersion modeling analysis, and other relevant PSD/Title V application package

contents in four to six weeks.

Please let me or Sara Carlson know if you have any q uestions or if we could be of help. Thanks for your

help.

Best Regards,

Rahul Pendse

Hello Eva,

Hope you had a good weekend. I just received additional information from Anadarko regarding one of

EPA's BACT questions in the incompleteness dete rmination letter. Also, I owe you Anadarko's expected

time frame when all information (including remodeling) could be submitted to EPA. Per our discussion last

week, I plan on contacting Stan Krivo to let him know about the remodeling efforts and discuss t he path

forward. I plan on providing update in this week. Feel free to let me know if you have any questions.

Best Regards,

Rahul Pendse

Hi Eva,

Just wanted to let you know that Trinity and Anadarko have started compiling a response letter to address

some of the comments in EPA's comments letter (DRAFT version). Although we have not gathered

information to address all the comments yet, it would be worthy providing available information to facilitate

the application review process. Please advise whether we should wait until we get a formal letter from

EPA or start addressing the comments based on available information. Thanks and have a good

weekend.

P.S.

- Any idea when could we expect to receive a formal letter from EPA?

Best Regards,

Rahul Pendse
