Wyoming Public Service Commission — Pipeline Safety Interpretation

Page 1PI-74-0116 May 22, 1974 Mr. Jon F. Jacquot Wyoming Public Service Commission Supreme Court Building Cheyenne, WY 82002 Dear Mr. Jacquot: This responds to your letter of May 14, 1974, asking whether Subpart I of 49 CFR Part 192 applies to gathering systems in nonrural areas. Subpart I applies to all pipelines subject to Part 192, including gathering lines in nonrural areas as described in Section 192.1. Where certain requirements in Subpart I specifically relate to transmission lines, these requirements apply with equal force to gathering lines as provided in section 192.9. We trust this satisfactorily answers your inquiry. Sincerely, /signed/ Joseph C. Caldwell Director Office of Pipeline Safety 192.1 1#
