Hampton, New Hampshire 03842 CPF 1-2024-026-WL Dear Mr. Meissner: From April 4, 2023 through June 2, 2023, a representative of the Pipeline and Hazardous Materials Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.), conducted an integrity management inspection of Granite State Gas Transmission Inc’s (Granite State) procedures and records. As a result of the inspection, it is alleged that you have 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. § 192.947 What records must an operator keep? An operator must maintain, for the useful life of the pipeline, records that demonstrate compliance with the requirements of this subpart. At minimum, an operator must maintain the following records for review during an inspection. (a) … (d) Documents to support any decision, analysis and process developed and used to implement and evaluate each element of the baseline assessment plan and integrity management program. Documents include those developed and used in support of any identification, calculation, amendment, modification, justification, deviation and determination made, and any action taken to implement and evaluate any of the program elements; Granite State failed to maintain records to support any decision, analysis and process used to implement and evaluate an element of its integrity management program. Specifically, Granite State failed to maintain in-line inspection assessment validation records in accordance with § 192.947(d). During the inspection, PHMSA requested records regarding validation of in-line inspection assessments. Granite State provided its ID Smith Pipeline Engineering – Final Report Validations, dated 06/29/23 (Validation Reports) and ILI Assessment Spreadsheet, dated 06/29/23 (Assessment Spreadsheet). The Assessment Spreadsheet listed (11) total pipeline segments which required an in-line inspection as the last performed reassessment. Furthermore, the Assessment Spreadsheet was not linked or referenced to the integrity management manual, nor was it included as part of its review processes. The Validation Reports were applicable to only (5) of the (11) total assessments which were issued final reports dated from calendar year 2020 through 2023. The Validation Reports, however, failed to include validation from each of the most recent assessment tool runs. When PHMSA asked where the validation reports were for the (6) missing pipeline segments: Maine South, New Hampshire South Extended, Gosling Road West, New Hampshire Portsmouth, New Hampshire Pease Lateral and Maine North which dated as far back as 2017 assessment runs, Granite State discussed how they do not require any actions to be taken or any validation report to be completed within a set timeframe. Subsequent to the inspection, Granite State stated that it is enhancing its ILI procedure to provide more detail on the timeframes for the validation reports and that it anticipated obtaining additional data for the Pease Lateral, NH South Extension, NH 8” Gas and Maine South. segments by the 3rd quarter of 2024. Therefore, Granite State failed to maintain records to support a decision, analysis, and process of an element of its integrity management plan, in accordance with § 192.947(d). Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed $266,015 per violation per day the violation persists, up to a maximum of $2,660,135 for a related series of violations.
