120191010M_Notice of Amendment_07222019_text.pdf, page 1Official PDFNOTICE OF AMENDMENT OVERNIGHT EXPRESS DELIVERY July 22, 2019 Mr. Brian Sheppard VP, Pipeline Operations Dominion Energy Transmission, Inc. 925 Whiteoaks Boulevard Bridgeport, WV 26330 CPF 1-2019-1010M Dear Mr. Sheppard: From October 16 – 18, 2018, a representative from the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.), inspected Dominion Energy Transmission, Inc.’s (Dominion) procedures for welding in Loudoun County, Virginia. On the basis of the inspection, PHMSA has identified the apparent inadequacy found within Dominion’s plans or procedures, as described below: 1. § 192.225 Welding procedures. (a) Welding must be performed by a qualified welder or welding operator in accordance with welding procedures qualified under section 5, section 12, Appendix A or Appendix B of API Std 1104 (incorporated by reference, see § 192.7) or section IX of the ASME Boiler and Pressure Vessel Code (ASME BPVC) (incorporated by reference, see § 192.7) to produce welds meeting the requirements of this subpart. The quality of the test welds used to qualify welding procedures must be determined by destructive testing in accordance with the applicable welding standard(s).#

120191010M_Notice of Amendment_07222019_text.pdf, page 2CPF 1-2019-1010M Dominion’s welding procedures qualified under section 5 of API Std 1104 were inadequate. Specifically, Dominion’s Weld Procedure DT-312SC-WOL 04/01/07 Rev.: 0 and DT-322SC-WOL 04/01/07 Rev.: 0 (Procedures) did not designate the maximum time between the completion of the root pass and hot pass, and the hot pass and 3rd pass, as required by section 5 of API Standard 1104 – Welding of Pipelines and Related Facilities, 20th Edition (API 1104). API 1104, Section 5.3.2.10 states: “The maximum time between the completion of the root bead and the start of the second bead, as well as the maximum time between the completion of the second bead and the start of other beads, shall be designated.” On January 15, 2016, API issued a technical interpretation clarifying the intent of Section 5.3.2.10 of API 1104 20th Edition, which stated “Yes, the intent of API 1104, Section 5.3.2.10 is to identify the maximum time between the 1st pass and 2nd pass and the maximum time between the 2nd pass and 3rd pass.” During the inspection, the Procedures were reviewed. The Procedures stated under Time Between Passes, “All passes for Fittings shall be completed without delay.” Therefore, DETI's Procedures failed to designate the time between weld passes as required by section 5 of API 1104, referenced in § 192.225(a).
