Pat - Let's shoot for Thursday morning, Feb 7th ... I still need to firm up on my end and will let you know 

tomorrow morning ... so I am thinking - 

9 AM (pacific)

and I will see about keeping my morning for RNRC (just in case)

In case Thursday falls through - I will come in on Friday - and in that case, 

8 AM (pacific)

and, likewise, will keep my morning for RNRC (just in case)

Pat,

Wanted to just send you a note confirming receipt. Thanks for outlining

specifics. This is very helpful. The information you provided, needless

to say, will need to be taken into consideration across the board for

our efforts.
Please note that I'll be checking in with Tom Mintz, our Regional

Counsel who has been involved with the Consent Decree, and to Gerardo

Rios, the Chief of our Permits Office.

 Also, will forward you, once again, availability for telecon regarding,

at least, the PSD permit. Let me digest what you all provided so I can

understand our next steps and get the telecon rescheduled.

Thanks much,

- Shirl

 MCU PSD and Title V Permits 

 

Shirley and Shaheerah,

Since we have been unable to connect on the phone over the past few

weeks, and in anticipation of our eventual teleconference, I'd like to

point out a few things regarding the PSD application prepared by

ExxonMobil in August-September 2006 for the MCU facility. Many of these

comments apply to the yet to be issued Title V permit as well.

 1. The PSD permit application still lists ExxonMobil and ExxonMobil

 contacts as the owner/operator. This should be changed throughout

 to Resolute Natural Resources Company.

 2. Resolute added a fifth electric-powered compressor to the MCU

 facility in 2007, at a cost of $9.5M. We did this in order to

 improve compressor reliability and try to minimize flaring. We're

 still in the start-up phase but are optimistic this should help

 reduce flare emissions.
 3. ExxonMobil used an unrealistically low Btu value for the flare gas

 for all of its Main Flare emission calculations and modeling. They

 used a range of 300 to 433 Btu. During 2007, we collected monthly

 flare gas samples that showed Btu ranging from 550 to 664. As a

 result, even through the volume of gas being flared has decreased,

 the resulting NOx and CO emissions have increased. The NOx and CO

 levels contained in the Consent Decree, the PSD application, and

 presumably the Title V application are too low and need to be

 revisited. We are currently running at about 98 percent of the NOx

 and CO limits. We need higher emission limits in both permits.

 4. ExxonMobil's use of incorrect Btu values has some impact on the

 air quality modeling.

 5. As I mentioned several months ago to Shaheerah, our mid-term plan

 is to add a gas refrigeration skid to the facility. Although

 actual emissions associated with the proposed skid will be low

 (primarily fugitives and a few low-Btu heaters) and constriction

 wouldn't start until the end of 2008 or beginning 2009, I wanted

 to give you both a heads-up.

Thanks - Pat
