Page 1December 2, 1975 Mr. Luke Ernst Luke Ernst and Associates, Inc. P.O. Box 32096 Decatur, GA 30032 Dear Mr. Ernst: In your recent letter received November 10, 1975, you ask if it is necessary that the reinforced epoxy resin pipe used in the Dresser Manufacturing Style 390 Meter Riser comply with all pertinent requirements of the Federal safety standards, such as Sections 192.59, 192.121, 192.123, 192.513, and Appendix B-1-ASTM D2517. The Office of Pipeline Safety Operations does not endorse or certify proprietary items. As a segment of a pipeline under the definition in Section 192.3, the epoxy resin pipe must comply with the requirements mentioned above and any other appropriate requirements of Part 192. Where a material specification is referenced by Part 192, it should be noted that only those editions listed in Appendix A or B are acceptable. Later published editions are not acceptable until they are approved and added to the appendices where appropriate. Thank you for your interest in pipeline safety. Sincerely, Cesar DeLeon Acting Director Office of Pipeline Safety Operations dal\192\121\75-12-02 1#
