�ttachmQnt for 1�FL �2 Liae <br />��, �g, �g: These questions are essentially the same. The operatinq <br />pressure can be any pressure up to and including the maximum pressure <br />allowed. If the,maximum pressure allowed is exceeded, safety devices <br />wii� shut down the operation. Therefore, there is no difference <br />between maximum and maximum allowable pressures. Operating pressure <br />will be anything less than maximum. For this line the maximum <br />operating pressure is 8�5 PSi with high pressure shutdown at 925 PSI. <br />'�50: The high point fox this line in Roseville is 930' at terminal <br />a�ility. The low point for this line in Roseville is 910' at <br />approximately County Road D. <br />�11: The elevation at Superior Junction is 1,130. The high and low <br />po n� ts were answered in question #�0 above. <br />��I2: The original installation was ERW pipe. Repair/replacement-work <br />�been done primarily with sea*nless pipe. All pipe is coated. <br />#21 and �22: These questions are essentially the same. The MN Office <br />o ipe ine 5afety conducts annual inspections of all operators in the <br />-State. These inspections can be standard, special or annual. Annual <br />uses the Federal iASpection form. Special inspections typical�y refer <br />to inspections of specific items like construction, R.�.W. clearinq, <br />or programs. Also, most operators are divided into inspection units <br />and not all of them are inspected annually. These are important points <br />to understand so that Lhe inspection process makes sense. The last NIN <br />OPS inspection of the Roseville area was July of 1993. <br />Standard Inspection: Interstate agency status provides authority and <br />the Federal form is used. <br />Annual Inspection: Can be a standard or special inspection. <br />Special Inspection: Can be follow-up or inspection of a specific item <br />like construction or a Drug program. <br />
