Is 800 a common range? 5 <br />Andrew Moore: For PSNC it is. Our supplier is Williams Transco and a majority of their pipelines are 6 <br />operated at 800 PSI so that is the pressure we get in them. That is what our pipelines operate at. 7 <br />David Blankfard: How large it the right of way currently? 8 <br />Matt Rhoads: The easements are 50 feet is the necessary right of way for having the two pipelines 9 <br />there. Most of these easements are from the 1950s where it was not common practice to specify a width 10 <br />but even in the 1950s to have two pipelines, which these easements permit, you needed at least 50 feet 11 <br />and, obviously they can speak to it better, but there has got to be room for if you dig you have to have 12 <br />your trench at the right for OSHA, a place to pile the dirt and all that sort of stuff. 13 <br />David Blankfard: What is the depth of the existing 10 inch? W hat is the cover of the existing 10 inch 14 <br />line? 15 <br />Rob Priester: It is going to vary throughout the existing line. 16 <br />Jeff Schmitt: What is the minimum? 17 <br />Andrew Moore: At the time it was constructed, there was no minimum. From our studies where we have 18 <br />gone and located the line and taken depth measurements, the … I want to say that the shallowest point 19 <br />we have identified has been 30 inches. 20 <br />David Blankfard: Has there been any problems with that existing 10 inch line in the last, since 1950 21 <br />when it was put in? 22 <br />Andrew Moore: No problems other than we did have a problem seven or eight years ago. As part of a 23 <br />new DOT project, we went out and relocated the part of the pipeline for them and after the relocation, 24 <br />they hit the pipeline so it was third party damage but nothing was no failure because of lack of 25 <br />maintenance or anything like that. 26 <br />David Blankfard: So you have an existing 10 inch that was put in 1950ish and now we are at 16 inch, 27 <br />what drove the 16 inch, why not a 24 or another 10? 28 <br />Andrew Moore: The existing 10 inch is reaching its capacity. In other words, we can’t really serve any 29 <br />additional loads off of that line so we need additional capacity so we are building this new line to meet 30 <br />our current needs and the needs we have currently prescribed and as well as for some additional future 31 <br />capacity. We feel the 16 inch will satisfy that for a good number of years just as the 10 inch has satisfied 32 <br />that for 60 years. Our intent is for this pipeline to satisfy that future load for another 10, 20, 30 years. 33 <br />Mark Micol: What is the average lifespan for the line? 34 <br />Andrew Moore: I don’t know that there is a … at this point in time; I don’t know that a lifespan is defined. 35 <br />For PSNC, our oldest pipeline, this is one of the oldest, our vantage line is the first pipeline that PSNC 36 <br />installed so our oldest pipeline is 60, 62 years old which is within the industry is young compared to other 37 <br />operators. You have pipelines that were built in the 1920s and 30s and are still in operation today. 38
