PHMSA received one public comment\nconcerning this special permit. This public comment is reviewed in the Final Environmental\nAssessment (FEA) and Finding of No Significant Impact (FONSI).\nThe CGT special permit application letter, Federal Register notice, Special Permit, FEA and\nFONSI, and all other pertinent documents are available for review in Docket No. PHMSA-2022-\n0084 in the Federal Docket Management System (FDMS) located on the internet at\nwww.Regulations.gov.\nAnalysis:\nBackground: On June 29, 2004, PHMSA published in the Federal Register (69 FR 38948) the\ncriteria it uses for the consideration of applications for class location change waivers, now being\ngranted or denied through a special permit. First, certain threshold requirements should be met on\na pipeline special permit segment for a class location change special permit to be granted. Second,\nthe age and manufacturing process of the pipe; system design, and construction; environmental,\noperating, and maintenance histories; and integrity management program elements are evaluated as\nsignificant criteria. These significant criteria are presented in matrix form and can be reviewed in\nthe FDMS, Docket No. PHMSA–RSPA-2004-17401. Third, special permits will only be granted\nwhen pipe conditions and active integrity management provides a level of safety greater than or\nequal to a pipe replacement or pressure reduction. The operator’s federal pipeline safety regulation\ncompliance history is also evaluated as part of the criteria matrix for acceptability prior to issuance\nof a special permit.\nThreshold Requirements: Each of the threshold requirements published by PHMSA in the June\n29, 2004, Federal Register notice is discussed below for the CGT special permit request.\n1) No pipeline segments in a class location changing to Class 4 location will be considered.\n• This special permit request is for special permit segments on the CGT 30-inch diameter\nML 100 and ML 200 pipelines and the 36-inch ML 300 pipeline, where a change has\noccurred from a Class 1 location to a Class 3 location.\n• CGT meets this requirement.\nPHMSA-2022-0084 – Columbia Gulf Transmission, LLC Special Permit Analysis and Findings – Kentucky\nPage 4 of 12\n\n<<<PAGE 5>>>\n\n2) No bare pipe will be considered.\n• The CGT special permit segments are externally coated with coal tar enamel.\n• CGT has not reported any coating issues such as disbonded coating.\n• CGT meets this requirement.\n3) No pipe containing wrinkle bends will be considered.\n• There are no wrinkle bends in the special permit segments.\n• CGT meets this requirement.\n4) No pipe segments operating above 72% of the specified minimum yield strength (SMYS) will\nbe considered for a Class 3 special permit.\n• The special permit segments operate at or below 72% SMYS.\n• CGT meets this requirement.\n5) Records must be produced that show a hydrostatic test to at least 1.25 x MAOP and 90% of\nSMYS.\n• The special permit segments on the CGT 30-inch diameter ML 100 and ML 200\npipelines and the 36-inch ML 300 pipeline were tested to at least 1.25 times the MAOP\nor Table 1 and Condition 1(b) will require a pressure test to 1.39 times MAOP.\n• CGT meets or will meet this requirement.\n6) Inline inspection (ILI) must have been performed with no significant anomalies identified that\nindicate systemic problems such as stress corrosion cracking (SCC).\n• CGT has run ILI tools on the CGT 30-inch diameter ML 100 and ML 200 pipelines and\nthe 36-inch ML 300 pipeline in 2015, 2016, 2019, and 2020 in the special permit\ninspection area. Attachment A - Listing of Columbia Gulf Transmission (CGT)\nSpecial Permit Segments details all ILI assessments and date of the assessment.\n• CGT has found two (2) crack features at Survey Station 2346+82 on special permit\nsegments 3, 4, and 7. The cracks were minor surface cracks and have been remediated.\n• CGT meets this requirement.\n7) Criteria for consideration of a class location change waiver, being considered through the\nspecial permit, published by PHMSA in the Federal Register (69 FR 38948), define a waiver\ninspection area (special permit inspection area) as up to 25 miles of pipe on either side of the\nwaiver segment (special permit segment).\nPHMSA-2022-0084 – Columbia Gulf Transmission, LLC Special Permit Analysis and Findings – Kentucky\nPage 5 of 12\n\n<<<PAGE 6>>>\n\n• A special permit would be contingent upon CGT’s incorporation of the special permit\nsegments in its written integrity management program as covered segments in a high\nconsequence area (HCA) in accordance with 49 CFR 192.903 and to assess and\nremediate threats to the special permit inspection area.\n• CGT’s defined special permit inspection areas 1, 2 and 3 are 63.72, 79.92, and 80.04\nmiles in length as detailed in Table 3 – Special Permit Inspection Areas.\nCriteria Matrix: The data submitted by CGT for the special permit segments has been compared\nto the class location change special permit criteria matrix. The data fall within the probable\nacceptance or the possible acceptance column of the criteria matrix, except for PHMSA\nenforcement findings which fall under the requires substantial justification.\n• The special permit segments fall in the probable acceptance column of the criteria\nmatrix for:\no Design stress, pipe material, depth of pipe cover, test pressure, test failures, type\nservice, pressure fluctuations, safety related conditions, leaks and failures, direct\nassessment, ILI type, ILI program, and damage prevention program.\n• The special permit segments fall in the possible acceptance column of the criteria matrix\nfor:\no Class 1 to 3 location, pipe manufacturer, pipe coating type (may shield cathodic\nprotection (CP)), local geology, CP, and HCA program.\n• The special permit segments fall in the requires substantial justification column of the\ncriteria matrix for:\no CGT has identified issues in girth welds within the special permit segments and\npipe girth weld records are not available. CGT will complete Special Permit\nCondition 6 – Girth Welds;\no The coating type may shield CP when disbonded, causing SCC.\n6 CGT will\ncomplete Special Permit Condition 7 – Stress Corrosion Cracking Threat; and\n6 Two (2) types of SCC are found on pipelines: High pH (9 to 11) SCC and near-neutral pH (6 to 8) SCC. Coal tar\nand asphalt coatings that are disbonded are more prone to having SCC.\nPHMSA-2022-0084 – Columbia Gulf Transmission, LLC Special Permit Analysis and Findings – Kentucky\nPage 6 of 12\n\n<<<PAGE 7>>>\n\no Inspection findings (Enforcement History) – PHMSA enforcements are in the “Past\nEnforcement History – January 1, 2011 through September 30, 2022” section\nbelow.\nOperational Integrity Compliance:\nTo inform PHMSA’s decision about whether a special permit could provide a level of safety\ngreater than or equal to a pipe replacement or pressure reduction and is consistent with pipeline\nsafety, PHMSA reviewed this special permit request to understand the known type of integrity\nthreats that are in the special permit segments and special permit inspection area. This integrity\ninformation was used to design special permit conditions to provide a systematic program to\nreview and remediate the pipeline for safety concerns. Additional operational integrity review and\nremediation requirements are required by this special permit to ensure that the operator has an\nongoing program to locate and remediate safety threats. These threats to integrity and safety\ninclude any issues with the pipe coating quality, CP effectiveness, operations damage prevention\nprogram, pipe depth of soil cover, weld seam and girth weld integrity, anomalies in the pipe steel\nand welds, and material and structures either along or near the pipeline that could cause the CP\nsystem to be ineffective. PHMSA has carefully designed a comprehensive set of conditions that\nCGT must implement to comply with this special permit.\nPast Enforcement History – January 1, 2011 through September 30, 2022:\nFrom January 1, 2011, through September 30, 2022, CGT was cited in five (5) enforcement actions\nwith a total of $33,100 in assessed civil penalties.
