Steve,=20
Darrell informed Burlington late on Friday that we will have an unplanned o= utage 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. =20 Thanks, Kim. =20 =20 -----Original Message----- From: =09Roensch, David =20 Sent:=09Friday, August 24, 2001 5:28 PM To:=09Harris, Steven Cc:=09Watson, Kimberly Subject:=09RE: SJ Pipe Settling The effect will be to the Burlington (low pressure) system only. We can s= till flow 800 mmcfd down the lateral, we will just need to make up the low = pressure volumes recieved from Burlington through the high pressure custome= rs. I've discussed with Darryl.... Today Burlington is flowing approximately 130 mmcfd. Limited to 800 mmcfd = down the lateral due to Gallups condition. =20 ---------------------- Forwarded by David Roensch/ET&S/Enron on 08/24/2001 = 04:24 PM --------------------------- From:=09Steven Harris/ENRON@enronXgate on 08/24/2001 06:08 PM CDT To:=09David Roensch/ET&S/Enron@ENRON cc:=09=20 Subject:=09RE: SJ Pipe Settling What will be the volume impact during the outage?

T= he Team had been working with Engineering on developing an action plan to a= ddress over the last several months. Upon a visual inspection we requested= that the Team contact a local contractor and have the pipe cover (dirt) re= moved immediately to allow the piping to relieve itself. This would provid= e the necessary time to follow up with Engineering and attain feedback on t= he 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 com= pleted 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 stre= ss concerns were eliminated. We requested that a structural engineer be se= nt 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 Di= ckenson (Trigon structural engineer) he mentioned that his immediate concer= n was how this much displacement could not induce high stresses. However, = no pipe coating cracks were visible so he wanted an opportunity to input th= e 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 desig= n factor, but without reviewing the data further he would not commit to a c= onclusion. We asked that he work through the evening, if required, to prov= ide 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 the= m on the estimated down time it would require in a worst case scenario to m= ake the repairs/replacements. (4 to 5 days) We then requested that the Ro= swell CDC (Ernie DeLosSantos) determine the availability of approximately 1= 50" 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) =20 Conclusion: =20 Mr. Dickenson called with the results this morning and informed us tha= t we appear to be exceeding allowable stress levels. The stress levels cal= culated 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-wel= ded 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, Pebdan= i, Minnoti ???) were set up to review the data with Mr. Dickenson and it wa= s decided to have Greg McIlwain on location Monday in conjunction with Mike= McCracken to initiate the necessary repairs. After much discussion with D= ickenson 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 un= it only so, the downtime is not expected to exceed 2 days (48 hours). Howe= ver, furhter evaluation by McIlwain will confirm timelines. =20 If anyone has questions through the weekend prior to Mondays call, I can be= reached at 520-853-3253.
