PHMSA has reviewed all public comments received for\nDocket Number PHMSA-2022-0035 through September 22, 2022. PHMSA received public comments\nconcerning this special permit request that have been addressed in the Final Environmental Assessment\nand Finding of No Significant Impact (FEA and FONSI).\nThe TGP special permit application letter, Federal Register notice, FEA, Finding of No Significant\nImpact, and all other pertinent documents are available for review in Docket No. PHMSA-2022-0035\nin the Federal Docket Management System (FDMS) located at www.Regulations.gov.\nAnalysis:\nBackground: On June 29, 2004, PHMSA published in the Federal Register (69 FR 38948) the criteria\nit uses for the consideration of applications for class location change waivers, now being granted or\ndenied through a special permit. First, certain threshold requirements should be met on a pipeline\nspecial permit segment for a class location change special permit to be granted. Second, the age and\nmanufacturing process of the pipe; system design, and construction; environmental, operating and\n3 If the special permit inspection area footage does not extent from launcher to receiver then the special permit inspection\narea would need to be extended.\nPHMSA-2022-0035 – Tennessee Gas Pipeline Company, LLC Special Permit Analysis and Findings – Tennessee\nPage 4 of 12\n\n<<<PAGE 5>>>\n\nmaintenance histories; and integrity management program elements are evaluated as significant criteria.\nThese significant criteria are presented in matrix form and can be reviewed in the FDMS, Docket No.\nPHMSA–RSPA-2004-17401. Third, special permits will only be granted when pipe conditions and\nactive integrity management provide a level of safety greater than or equal to a pipe replacement or\npressure reduction. The operator’s Federal pipeline safety regulation compliance history is also\nevaluated as part of the criteria matrix for acceptability prior to issuance of a special permit.\nThreshold Requirements: Each of the threshold requirements published by PHMSA in the June 29,\n2004, Federal Register notice is discussed below regarding the TGP special permit request.\n• No pipeline segments in a class location changing to Class 4 location will be considered.\n• This special permit request is for 17 special permit segments where a change has occurred\nfrom a Class 1 or Class 2 location to a Class 3 location.\n• TGP meets this requirement.\n• No bare pipe will be considered.\n• The special permit segments are externally coated with coal tar enamel or wax.\n• TGP meets this requirement.\n• No pipe containing wrinkle bends will be considered.\n• There are no reported wrinkle bends in the special permit segments.\n• TGP meets this requirement.\n• No pipe segments operating above 72% of the specified minimum yield strength (SMYS) will be\nconsidered for a Class 3 special permit.\n• The special permit segments operate at or below 72% SMYS.\n• TGP meets this requirement.\n• Records must be produced that show a hydrostatic test to at least 1.25 time the MAOP. The records\nshould include test pressure, year of the test, test duration, and pressure test percent of MAOP for\neach pipeline:\n• TGP has communicated that all special permits segments have been tested to at least 1.25\ntimes the MAOP.\n• TGP meets this requirement.\n• In-line inspection (ILI) must have been performed with no significant anomalies identified that\nindicate systemic problems such as stress corrosion cracking (SCC).\nPHMSA-2022-0035 – Tennessee Gas Pipeline Company, LLC Special Permit Analysis and Findings – Tennessee\nPage 5 of 12\n\n<<<PAGE 6>>>\n\n• TGP ran a high-resolution magnetic flux leakage (HR-MFL) ILI for corrosion and\ndeformation ILI for denting.\n• TGP meets this requirement.\n• Criteria for consideration of a class location change waiver, being considered through the special\npermit, published by PHMSA in the Federal Register (69 FR 38948), define a waiver inspection\narea (special permit inspection area) as up to 25 miles of pipe on either side of the waiver segment\n(special permit segment).\n• TGP has identified longer segments surrounding each special permit segment as the special\npermit inspection area. These segments have been extended to the entire segment length\nbetween the upstream launcher and downstream receiver on each ILI segment that contains\none (1) or more special permit segments.\nCriteria Matrix: The data submitted by TGP for the special permit segments have been compared to\nthe class location change special permit criteria matrix.\n• The following special permit segments fall in the probable acceptance column of the criteria\nmatrix for:\no Class location change (special permit segments 672, 673, 675, 676, 678, and 679),\ndesign stress, depth of pipe cover, test pressure, test failures, local geology, type of\nservice, pressure fluctuations, safety related conditions, direct assessment, ILI type, and\ndamage prevention program.\n• The following special permit segments fall in the possible acceptance column of the criteria\nmatrix for:\no Class location change (Special permit segments 667, 671, 674, 677, 680, 707, 708, 708,\n710, 714, and 715) pipe manufactured in 1954, 1959, and 1965; Coating type (coal tar\nenamel or wax coating which may shield CP when disbonded, causing SCC.\n4)\n• The following special permit segment fall in the required substantial justification column of\nthe criteria matrix for:\no Special permit segment 710 has 36-inch diameter ERW seam type.\n4 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 and\nasphalt coatings that are disbonded are more prone to have SCC.\nPHMSA-2022-0035 – Tennessee Gas Pipeline Company, LLC Special Permit Analysis and Findings – Tennessee\nPage 6 of 12\n\n<<<PAGE 7>>>\n\nOperational Integrity Compliance:\nTo inform PHMSA’s decision about whether a special permit could provide a level of safety greater\nthan or equal to a pipe replacement or pressure reduction and is consistent with pipeline safety,\nPHMSA reviewed this special permit request to understand the known type of integrity threats that are\nin the special permit segments and special permit inspection areas. This integrity information was\nused to consider special permit conditions to provide a systematic program to review and remediate the\npipeline for safety concerns. Additional operational integrity review and remediation requirements are\nrequired by this special permit to ensure that the operator has an ongoing program to locate and\nremediate safety threats. These threats to integrity and safety include any issues with the pipe coating\nquality, cathodic protection effectiveness, operations damage prevention program, pipe depth of soil\ncover, weld seam and girth weld integrity, anomalies in the pipe steel and welds, and material and\nstructures either along or near the pipeline that could cause the cathodic protection system to be\nineffective. PHMSA has carefully designed a comprehensive set of conditions that TGP must\nimplement to comply with this special permit.\nPast Enforcement History – January 1, 2012, through January 22, 2023:\nDuring January 1, 2012, through January 22, 2023, TGP was cited in 23 enforcement actions with a total of\n$232,600 in assessed civil penalties.

To ensure TGP properly\nimplements the special permit conditions, TGP will be required to give PHMSA an annual review of\ntheir compliance with the special permit.\nPHMSA finds the issuance and full implementation of this special permit that waives the requirements\nof 49 CFR 192.611(a) and (d) and 192.619(a) for a class location change to a Class 3 location is not\ninconsistent with pipeline safety. This special permit requires TGP to implement the special permit\nconditions that include safety requirements on the operations, maintenance, and integrity management\nof the special permit segments and the special permit inspection areas.

TGP requested a special permit to waive compliance\nwith 49 CFR §§ 192.611(a) and (d), and 192.619(a) for Class 1 to Class 3 location changes on 17\npipeline segments for approximately 8.011 miles of 30-inch diameter and 36-inch diameter gas\ntransmission pipelines (Pipelines) located in Cheatham, Dickson, Hickman, and Robertson\nCounties, Tennessee. A gas transmission pipeline operator is required by 49 CFR § 192.611 to\nconfirm or revise the maximum allowable operating pressure of a pipeline segment where the class\nlocation has changed as defined in 49 CFR § 192.5.\nOn June 1, 2022, PHMSA published a Federal Register notice (87 FR 33302) announcing the\nSpecial Permit Request. The Special Permit Request letter, Final Environmental Assessment\n(FEA) and Finding of No Significant Impact (FONSI), Special Permit Analysis and Findings\n(SPAF), and all other pertinent documents for this special permit are available in Docket No.\nPHMSA-2022-0035 in the Federal Docket Management System located at www.regulations.gov.\n2\nSubject to the stated terms and conditions, PHMSA grants this special permit (enclosed) based on\nthe information provided by TGP and the findings set forth in the SPAF, FEA, and FONSI. This\nspecial permit provides relief from certain provisions of the Federal pipeline safety regulations for\nthe Pipelines and requires TGP to comply with conditions and limitations designed to maintain\n1 Tennessee Gas Pipeline Company, LLC is owned by Kinder Morgan, Inc.\n2 https://www.regulations.gov/docket?D=PHMSA-2022-0035.\n\n<<<PAGE 2>>>\n\npipeline safety as defined in the special permit. Note that in accordance with 49 CFR § 190.341(j),\nPHMSA reserves the right to revoke, suspend, or modify this special permit if circumstances occur\nin which its continuance would be inconsistent with pipeline safety.
