Amoco Oil Pipeline Replacement <br />In a continued effort for correcting encroachments Amoco Oil Company identified <br />an area of 25 trailer homes above or near the products pipeline in Little Canada, <br />Minnesota. After attempting legal action to get the owners of the North Star <br />Estates to move, Amoco now is proposing to adjust and upgrade this pipeline <br />segment for the safety of the public. <br />The pipeline is a 10 inch high pressure pipeline which transports refined <br />products. The project was identified in 1989 and originally was to replacement <br />and adjust the pipeline in a marshy area directly north of the trailers. <br />However, after completing the design and ordering the materials we found out that <br />the City of Little Canada was to construct a hydraulic retention pond in this <br />same area to provide flood protection to the residents of the North Star Estates <br />trailer park. <br />It is now planned to relocate the pipeline approximately 35 ft north of the <br />trailers and 15 ft south of the retention pond. This line segment is <br />approximately 1,500 ft in length and will run from the parking area on the west <br />edge, along the retention pond, across Country Road and will tie -in at the <br />eastern end near I -35. The retention pond runs form approximately Station 0 +00 <br />to Station 1175 +00. An adjustment will be made at Station 1175 +00 to increase the <br />spacing distance from 35 ft to 75 ft from the trailer homes. Also a bored <br />crossing of Country Road will be required to enable a tie -in to the existing <br />pipeline. I have attached photographs and a diagram for your convenience and <br />review of the proposed route. <br />The pipeline will be a heavier wall thickness pipe and will be an additional one <br />foot below grade, for a total cover of 5 ft. A hydrostatic pressure test and <br />radiographic examination of all welded joints will be conducted to Amoco's Safety <br />Policy. <br />This pipeline replacement and adjustment to Amoco's facilities is to increase the <br />safety to the people of the North Star Estates and the community of Little <br />Canada. This corridor is the only option available for the pipeline relocation, <br />and your approval of this permit is requested. <br />Dennis A. Placke <br />Staff Engineer <br />Page 21 <br />
