As a result of the inspection, it is alleged that Texas Eastern Transmission, LP’s (TET) has committed a probable violation of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The item inspected and the probable violation is: 1. § 192.605 Procedural manual for operations, maintenance, and emergencies. (a) General. Each operator shall prepare and follow for each pipeline, a manual of written procedures for conducting operations and maintenance activities and for emergency response. For transmission lines, the manual must also include procedures for handling abnormal operations. This manual must be reviewed and updated by the operator at intervals not exceeding 15 months, but at least once each calendar year. This manual must be prepared before operations of a pipeline system commence. 1 Pipeline Safety: Safety of Gas Transmission Pipelines: MAOP Reconfirmation, Expansion of Assessment Requirements, and Other Related Amendments, 84 Fed. Reg. 52,180 (October 1, 2019).#

32025027NOPV_Final Order_10202025_(24-299195)_text.pdf, page 6Appropriate parts of the manual must be kept at locations where operations and maintenance activities are conducted. TET did not follow its manual of written procedures in accordance with § 192.605(a). Specifically, TET did not follow its “Pipeline Integrity – Integrity Management Plan” (IMP), section 7.3.1 which required the identification of Moderate Consequence Areas (MCA) for the purpose of conducting baseline assessments in accordance with § 192.710(b). Section 7.3.1 referenced procedure OC-52.201 – “HCA/MCA Identification Process” which states in section 3 that “HCAs and MCAs shall be identified, evaluated, and published once per calendar year, not to exceed a period of 15 months for all US Enbridge (as built/in service) gas transmission pipelines.” During PHMSA’s inspection, PHMSA inspectors reviewed TET’s pipeline system for MCAs and determined that six MCAs were missed at the time of the inspection. A historical review of publicly available satellite imagery found that these locations existed prior to the effective date of the regulation, which was July 1, 2020. The missed MCAs discovered during PHMSA’s inspection were as follows: Location • 40.439063°, -78.978202° - ARMA-LILL/12 was not designated as an MCA even though it met the 5 buildings intended for human occupancy density count within a potential impact radius. The adjacent lines ARMA-LILL/19 and ARMA-LILL/27 were designated as MCAs within this area. • 40.338835°, -75.078314° - EAGL-LAMT/1 line segment had an MCA identified in this area due to the house density. However, the MCA should have been longer than what was designated in the map. This MCA was right next to a designated high consequence area (HCA) for this line. The adjacent line EAGL-LAMT/2 was designated an HCA throughout this entire area. • 40.116594°, -75.272552° - EAGL-LAMT/1-B-2 had an MCA established for the PA Turnpike (Hwy 276). However, the MCA stopped short of a location where the pipe segments met the house density count requirement. Therefore, the MCA should have been expanded to include this area. • 40.134355°, -75.248624° - EAGL-LAMT/1-B-1 did not have an MCA designated at this location, despite it meeting the criteria due to the housing density. • 40.111930°, -75.270010° - EAGL-LAMT/1-B-1 and EAGL-LAMT/1-B-2 were not identified MCAs at this location, despite meeting the criteria due to housing density. This area was adjacent to existing MCAs on both lines. • 40.081469°, -75.134934° - EAGL-LAMT/1-F did not have an MCA designated in this area, despite meeting the criteria due to housing density. Thus, TET did not follow its IMP, Section 7.3.1, for the identification of MCAs in six locations, in violation of § 192.605(a).#
