Steve, 

Darrell informed Burlington late on Friday that we will have an unplanned outage next week for two days.  We will talk with their commercial folks on Monday morning to make sure that they are in the loop.  We anticipate that we can be back online by September business so Burlington can proceed ahead with their September business as usual.  We will also talk with the other SJ players to help fill the gap so that we can maintain 800,000MMBtu/d down the lateral while Burlington is down.  

Thanks, Kim.

The effect will be to the Burlington (low pressure) system only.   We can still flow 800 mmcfd down the lateral, we will just need to make up the low pressure volumes recieved from Burlington through the high pressure customers.  I've discussed with Darryl....

Today Burlington is flowing approximately 130 mmcfd.  Limited to 800 mmcfd down the lateral due to Gallups condition.

What will be the volume impact during the outage? Thanks.

A conf. call has been set up for Monday morning 9:00 a.m. CST to discuss a force majeure situation on the #3 unit at the San Juan Compressor Station.  877-795-3687 pin 475577 

Overview:  (for those uninvolved to date)
     In a walk through of the San Juan Station with the Team Thursday evening 8/16 it was noted that severe settling issues on yard piping existed.  The Team had been working with Engineering on developing an action plan to address over the last several months.  Upon a visual inspection we requested that the Team contact a local contractor and have the pipe cover (dirt) removed immediately to allow the piping to relieve itself.  This would provide the necessary time to follow up with Engineering and attain feedback on the status of the project and implement remedies.  The Team had a contractor on location the following Monday 8/20, and work removing the cover was completed this Monday 8/27.  However, the expected results were not achieved.  In other words the piping did not spring back to the degree that pipe stress concerns were eliminated.  We requested that a structural engineer be sent to the site immediately to evaluate the integrity of the piping.  He was on location Thursday morning (8/29).  In a phone conversation with Phil Dickenson (Trigon structural engineer) he mentioned that his immediate concern was how this much displacement could not induce high stresses.  However, no pipe coating cracks were visible so he wanted an opportunity to input the data in a model and evaluate prior to making any recommendations.  He did offer, that at a minimum, we stand a good chance of exceeding the .5 design factor, but without reviewing the data further he would not commit to a conclusion.  We asked that he work through the evening, if required, to provide the necessary information with regards to the pipes integrity.   While waiting on Trigons report, we notified the Team and asked that they contact Foutz & Bursham (local pipeline contractor) and get an evaluation from them on the estimated down time it would require in a worst case scenario to make the repairs/replacements.  (4 to 5 days)  We then requested that the Roswell CDC (Ernie DeLosSantos) determine the availability of approximately 150" of X42 356 wall 10" pipe, 12 ea. Y42  365 wall 90's, and 1 ea. Y42 365 wall 45.  (all material is available at Redman Supply in Farmington)  

Conclusion:    
     Mr. Dickenson called with the results this morning and informed us that we appear to be exceeding allowable stress levels.  The stress levels calculated by Dickinson were in excess of yield as follows:  1.09% of SMYS at the connection between the recycle/surge line and the discharge header, and 1.01% of SMYS at the elbow immediately outside the building wall on the 10" recycle line.    His recommendation was that the piping be cut and re-welded to return the piping to a lower stress condition and that suitable pipe supports, not subject to subsidence, be provided.

     Conference calls with Engineering (Spalding, Eisenstein, Rance, Pebdani, Minnoti ???) were set up to review the data with Mr. Dickenson and it was decided to have Greg McIlwain on location Monday in conjunction with Mike McCracken to initiate the necessary repairs.  After much discussion with Dickenson with regards to the modeling performed, Engineering indicated that the system is Operational and therefore we will remain loaded until early next week when repairs are made.  The repairs will be isolated to the #3 unit only so, the downtime is not expected to exceed 2 days (48 hours).  However, furhter evaluation by McIlwain will confirm timelines.  

If anyone has questions through the weekend prior to Mondays call, I can be reached at 520-853-3253.
