L. Crawford, Jr.\nVice President\nMid-Continent Pipe Line Company\n907 South Detroit Avenue\nTulsa, Oklahoma 74120\nDear Mr. Crawford:\nYour letter of August 11, 1989, to the Office of Pipeline Safety\n(OPS), with enclosures, gave notice as required by 49 CFR ?195.8 of\nyour intention to operate hazardous liquid pipelines constructed of\na material other than steel pipe. Specifically, Mid-Continent\nproposes to install and operate certain crude oil gathering lines\nin Oklahoma City, Oklahoma, using polyethylene plastic pipe. In an\nearlier communication with Dennis Fothergill of the Oklahoma\nCorporation Commission, we found the proposed plastic pipelines to\nbe subject to 49 CFR Part 195.\nAdditional information and data concerning this notice were\nsupplied verbally by Mr. Brad Lange to an OPS senior staff engineer\non August 22, 1989. Mr. R. D. McKenzie of your company provided\nadditional information and data by letter of August 29, 1989.\nAlso, Mr. McKenzie on September 14, 1989, concurred by telephone\nwith the two lists of regulations included in Enclosures 1 and 2\nwhich must be complied with concerning these pipelines.\nFrom the above described sources, the following is our\nunderstanding concerning your proposal:\nE Installation will consist of a total of approximately\n38,800 feet of polyethylene plastic pipe.\nE The pipe will be 3, 4, and 6 inch, SDR-11, PE 3408,\nPhillips Driscopipe 6400.\nE The pipe and fittings will be manufactured in compliance\nwith ASTM D2513, \"Standard Specification for\nThermoplastic Gas Pressure Pipe, Tubing, and Fittings.\"\nE Joining of polyethylene pipe will be by heat fusion.\nE The pipelines will ne installed with a minimum cover of\n48 inches.\nDB\nC:\\WP51\\INTERPRT\\195\\3\\89-09-19\n1\n\n<<<PAGE 2>>>\n\nE The pipelines will transport crude oil in a gathering\nsystem in a commercial/residential area classified per\n49 CFR ?192.5 as Class location 3.\nE Each Lease Automatic Custody Transfer (LACT) station\nfeeding the system will be equipped with an automatic\nshut-down which will deactivate the pump to assure the\nsystem operates below the maximum design temperature of\n100?F.\nE The pipelines are designed for an estimated life of 50\nyears.\nE The plastic pipelines will provide no significant\nincrease in hazards to the water table or any body of\nwater in their normal operation as compared with steel\npipelines in the same service.\nE Design of plastic pipe will comply with 49 CFR ?192.121\nwith a factor of 0.20 being substituted for the 0.32\nfactor shown in the equation.\nE The polyethylene pipelines shall be designed and\nconstructed in accordance with the requirements\npertaining to plastic pipelines contained in 49 CFR Part\n192 and listed in Enclosure 1 to this letter. Otherwise\nthe pipelines shall comply with the requirements of 49\nCFR Part 195 listed in Enclosure 2 to this letter.\nBased upon the above information and our technical evaluation of\nthe safety of the proposed pipelines, we have determined in\naccordance with 49 CFR ?195.8 the use and operation of polyethylene\nplastic pipe in the above described manner would not be unduly\nhazardous and the transportation may proceed as planned.\nSincerely,\n/signed/\nRichard L.
