discontinued using the oid one. The new rack is of the "bottom loading type" and is an open buifding with an overhead roof.

Pipel�nes, Figures 1'I, 13, and 14 ♦ A 10 inch pipefine is bi-directional, pumping to the Rosevi�le terminal or #oward Dubuque. When product in this line is flowing toward Dubuque, the pressure is normaliy 650 psi. at the discharge side of the p�mp in RoseviliE_ When the line pumps product to Roseville, pressure is 10 to 40 psi. This line is not in continuous use. At the terminal in Roseville, there is a motor operated valve controlled either from the terminal or from Tulsa, 4klahoma. This line, #raversing easterly ihraugh the center of Roseville, exits Rosev+iis at Rice Street about a block south of Roseville's northern border. A block east of Rice Street into Little Canada, t�ere is a manual and an electrically (motor} opera#ed �alve, Figure 8, which can be controlled from Tulsa or the terminal. This Eine was built in 1947. ♦ An eight inch pipeline, northerly from the terminal, exits at Roseville's northwest corner. This line ends at the Amoco refinery in Mandan, N.D. Produci flows in this line from Mandan io Roseville and is in constant use_ The average pressure in this Iine at Roseville is � 50 psi. This [ine was buift in 1947. There is a manuai and motor operated valve at the terminal. The nearest �alve beyond Roseville is electrically operated and is located in Minneapolis near where it crosses the Mississippi River, as shown in Figure 13. This line and the 10" line were'Smart Pig'* tested in Roseville in 1987 ar�d '1990 respectively. They have not been hydrostatically tested. ♦ Two pipelines operate soiely between the Amoco Terminal and the Williams Pipe Line Company (Wilfiams) terminal. These fines and others in the area of tt�e terminais are shown in Figure '!4. The eight inch fi�e between the two terminals is used to transmit gasoiine and fue! oil bidirectonalfy between the two terminals. The other pipeline is an eight inch pipe above grade at the Amoco Terminak and a six inch pipe below County Road "C" a�d belaw grade at the Wilfiams Terminal. This iine is used to transmit ethanal from the Williams terminal to the Amoco terminal. 3-4
