As a result of the inspection, it is alleged that BW has committed probable violations of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected and the probable violations are: 1. § 192.607 Verification of Pipeline Material Properties and Attributes: Onshore steel transmission pipelines. (a) . . . . (b) Documentation of material properties and attributes. Records established under this section documenting physical pipeline characteristics and attributes, including diameter, wall thickness, seam type, and grade (e.g., yield strength, ultimate tensile 1 Boardwalk Pipelines, LP, is the primary safety relation for both Texas Gas Transmission, LLC, and Gulf South Pipeline Company, LLC. Both Texas Gas Transmission, LLC, and Gulf South Pipeline Company, LLC, are subsidiaries of Boardwalk Pipelines, LP. See Our Business, BOARDWALK PIPELINES, https://www.bwpipelines.com/our-business/default.aspx (last accessed August 12, 2024). The inspection covered both assets and therefore both assets will be referred to as Boardwalk Pipelines, LP (BW Pipelines). 2 84 Fed. Reg. 52180 (Oct. 1, 2019). strength, or pressure rating for valves and flanges, etc.), must be maintained for the life of the pipeline and be traceable, verifiable, and complete. Charpy v-notch toughness values established under this section needed to meet the requirements of the ECA method at § 192.624(c)(3) or the fracture mechanics requirements at § 192.712 must be maintained for the life of the pipeline. BW Pipelines failed to maintain records for material verification that are traceable, verifiable, and complete (TVC), per the requirements of § 192.607(b). Specifically, BW Pipelines relied on a single source to meet the requirement of TVC. BW Pipelines provided a record of a single source to demonstrate TVC of a segment of pipe installed in 1928. The example was presented to PHMSA in a PowerPoint presentation, entitled “Boardwalk TVC Program,” slides 21-23, Example 3. The single record was created in 1969; the pipe was installed in 1928. There was no indication of where the information contained in the record was sourced from, as it was clearly transcribed from another document. BW Pipelines maintained that in cases of “old” pipe installation, a single source record is the only record it maintains for TVC determination. This record only included the date of installation, station numbers, and pipe attributes of outside diameter and wall thickness, which is not sufficient to meet the requirements of § 192.607(b), as it did not include specific characteristics and attributes including yield strength, ultimate tensile strength, and pressure ratings. No other record was provided to demonstrate full TVC. However, even the information included within the record (i.e., the date of installation, station numbers, and pipe attributes of outside diameter and wall thickness), is inadequate to demonstrate TVC of those elements. This is because a single source record, such as this relevant record, cannot form the basis of reasonable justification for TVC determination for several reasons. First, it cannot meet the definition of traceable. Traceable records are those which can be clearly linked to original information about a pipeline segment or facility. Information from a transcribed document should be verified with complementary or supporting documents. Second, these types of records cannot be verified. Verifiable records are those in which information is confirmed by other complementary, but separate, documentation. Third, these types of records are often “incomplete.” Complete records are those in which the record is finalized as evidenced by a signature, date, or other appropriate marking such as a corporate stamp or seal. Here, the relevant record cannot serve as an adequate basis for TVC because it (1) did not have a complementary or supporting documentation, (2) cannot be verified by complementary or supporting documentation, and (3) did not have any indication of being “finalized,” in addition to (4) missing other specific characteristics and attributes (yield strength, ultimate tensile strength, and pressure ratings). Thus, the single record provided did not meet the Traceable, Verifiable or Complete aspects of TVC; therefore, the pipe should not have been considered TVC’d. As a result, the attributes must be opportunistically obtained through § 192.607(c) efforts. 2. § 192.624 Maximum allowable operating pressure reconfirmation: Onshore steel transmission pipelines. (a) Applicability. Operators of onshore steel transmission pipeline segments must reconfirm the maximum allowable operating pressure (MAOP) of all pipeline segments in accordance with the requirements of this section if either of the following conditions are met: (1) . . . . (2) The pipeline segment's MAOP was established in accordance with § 192.619(c), the pipeline segment's MAOP is greater than or equal to 30 percent of the specified minimum yield strength, and the pipeline segment is located in one of the following areas. . . . BW Pipelines did not include all of its applicable § 192.619(c) lines in the MAOP Reconfirmation Plan, as required by § 192.624(a)(2). BW Pipelines provided PHMSA the following list of § 192.619(c) lines which were not included in the reconfirmation plan: Pipeline Mileage MLS 26-1TT 21.721 MLS 26-2TT 18.168 BAE 26-1TT 5.432 BAE 30-1TT 4.900 EIS 18-1TT 3.027 Index 129 2.814 Index 300 2.066 EUT 20-1TT 1.058 Index 311 0.499 Index 130 0.346 Index 266-L 0.122 Index 266 0.103 EIS 18-2TT 0.058 EUR-16-1TT 0.003 EUR-16-2TT 0.003 SHC 20-1TT 0.002 Index 287 0.001 Index 205.4 0.001 Total 60.3 BW Pipelines explained to PHMSA that these pipelines were not included in its reconfirmation plan because it had a valid hydrotest for each line. Section 192.624(a)(2) requires that all pipelines whose MAOP was established under § 192.619(c) must be reconfirmed if they are located in a Class 3 or 4, or an MCA that can accommodate an inline inspection tool. The regulation does not provide that § 192.619(c) pipe that was previously hydrostatically tested is exempt from § 192.624(a)(2) applicability. The line segments in question must be included in the reconfirmation plan to be reconfirmed as required by § 192.624(a)(2).
