<br />that the actual height above ground level is indicated so that people will be able to understand <br />that. Mr. Diehl stated that the height above ground range from 52 feet to 71 feet. Mr. Diehl <br />provided an information packet to the audience regarding the service area for all of the <br />substations in the Denver Metro area. There is a chart showing each structure number with the <br />height above ground listed next to it, as well as a map showing where the structures are <br />specifically located along the route. There is also a table discussing various alternatives for a <br />single pole, H-frame, H-frame tall or H-frame same height, and a magnetic field chart of the <br />existing line and the maximum conditions and the magnetic fields under the proposed new line. <br />There is also an audible noise chart based on the future H-frame, existing H-frame and future <br />single-steel pole. <br /> <br />Mr. Diehl stated that at least 62% of the load growth is attributed directly to Louisville. There is <br />a misconception that the line is being updated to serve developments outside of Louisville. That <br />is not true. Other means are being used to service growth that is occurring outside of Louisville, <br />other than upgrading this line. <br /> <br />Mr. Diehl introduced the Staff that will be available to answer questions. <br /> <br />Commission Questions: <br /> <br />Commissioner McAvinew asked for a breakdown of the lump numbers combining operating costs <br />and maintenance costs. <br /> <br />Commissioner Leh asked what the status was of Public Service attempting to site and construct a <br />new substation and transmission line south of Jefferson County. What else is being done to <br />service our neighbors to the south? <br /> <br />Mr. Diehl, PSCO, stated that around the Great Western Reservoir they are proposing a substation <br />transmission hook-up to serve the development south of Broomfield. <br /> <br />Larry Keith, with Greystone, a consultant for PSCO on this application, 5231 South Quebec <br />Street, Greenwood Village, CO 80111. Mr. Keith stated that this substation will be located on <br />the north side of Interlocken Garden, west of Wadsworth and north of Highway 128. The <br />temporary substation was permitted for a two-year period while the new substation in mind is <br />being sited and permitted. A siting study has been conducted to tap the existing line that runs <br />south from the Valmont power plant in Boulder to Public Service Company facilities in the <br />northwest metropolitan area in Arvada. That line crosses the Department of Energy Rocky Flats <br />Environmental Technology site. The line is located approximately 3 miles west of Indiana Street. <br /> PSCO has met with cities of Westminster and Broomfield whose jurisdiction the line would <br />primarily cross once it exists the area. PSCO is still working with the Rocky Flats to see where <br />the best location to come off of the Rocky Flats property is. That is supposed to be in service in <br />October of 2001, which provides about a six-month window before May 2002 when the <br />temporary substation is supposed to be removed. It is being actively pursued at this time. <br /> <br /> 3 <br /> <br />
