Kinder Morgan Natural Gas Division 100 I Louisiana Street, Suite I 000 Houston. Texas 77002 Docket No. PHMSA-2016-0004 Dear Mr. Buchler: On January 11 , 20 16. T ennessee Gas Pipeline Company, L.L.C. (TGP) wrote to the Pipeline and Hazardous Materials Safety Administration (PHMSA) requesting a special permit to waive compliance from PHMSA ·s pipeline safety regulation in 49 CFR ** 192.6 11 (a) and (d). 192.619(a), and 192.5 for pipeline segments where the class location of the segment had been changed in accordance with* 192.5(c), cluster rule. The regulation requires confirmation or revision of the maximum allowable operating pressure (MAOP) of a pipeline segment where the class location has changed. T he special permit request is for 192 segments and 49.00 miles of the TGP natural gas transmission pipeline system located in the states of Kentucky. Louisiana. Mississippi. New Jersey. New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia. The pipeline segments are generally short in length, not continuous . and are located in multiple states and counties/parishes within those states. T he regulatory relie f from 49 CFR ** 192.611. 192.6 19 and 192.5 through a special permit would include additional time (5-years) to either replace or pressure test the pipeline segments in the class location sliding mile and outside the cluster area. where there arc over I 0 dwellings for human occupancy. Pipeline segments w ith I 0 or fewer dwellings for human occupancy outside the cluster area. but w ithin the sliding mile. would not be replaced and TGP would be required by the special permit conditions to implement procedures to maintain pipeline safety by identifying, assessing, and rcmediating integrit y threats to the pipeline segments. PHMSA is granting this special permit (enclosed). which will allow TGP to continue to operate segments of the TGP pipeline at the ir current MAOPs by implementing integrity management practices as defined in the special permit conditions until the pipe is replaced. pressure tested. or remecliatecl. This special permit provides re lief from the Federal pipe line safety regulations for <<>> the TGP special permit segments and requires TGP to compl y w ith certain conditions and limitations designed to maintain pipeline safety. PHMSA grants this special permit based on the findings set forth in the "Special Permit Analysis and Findings" document, which can be read in its entirety in Docket No. PHMSA-2016-0004 in the Federal Docket Management System (FDMS) located on the internet at www.Regulations.gov. My staff would be pleased to discuss this matter or any other regulatory matter with you.

TGP requests that PHMSA waive compliance from 49 Code of Federal Regulations (CFR) §§ I92.6 Il (a) and (d), 192.6 19(a), and 192.5 for 192 segments and 49.00 miles of natural gas transmission pipeline as described in Appendix A? Pipeline System Affected: This special permit request applies to 192 pipeline segments and 49.00 miles of natural gas transmission pipeline operated by TOP and located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia where a change has occurred from an original Class 1 location to a Class 3 location. This special 1 Tennessee Gas Pipeline Company L.L.C. is owned by Kinder Morgan, Inc. 2 Appendix A of this special permit lists the pipeline special permit segment location (County and State), MAOP, class location, diameter, wall thickness, grade, seam type, boundaries, and other attributes. Appendix A can be reviewed in Docket PHMSA-20 16-0004 at www.regulations.gov. Page 1 of 10 PHMSA-2016-0004 - Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> permit allows TGP to continue to operate the 192 pipeline segments and 49.00 mites at their cunent maximum allowable operating pressure (MAOP). Special Permit Request: TGP submitted an application to PHMSA on January II , 20 I6, for a special permit seeking relief from the Federal pipeline safety regulations in §§ 192.6II(a) and (d), I92.6I9(a), and I92.5 for 192 segments and 49.00 miles of natural gas transmission pipeline as described in Appendix A of the Special Permit Conditions. The special permit segments are located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia. This special permit applies to the special permit segments listed in Appendix A. Special permit segments shall be divided into two (2) categories: Type A special permit segments and T ype B special permit segments. • Type A special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § I92.5(c), of more than 10 buildings intended for human occupancy in a "class location unit" and for which the MAOP has.not been confirmed in accordance with 49 CFR § 192.6 11 (a). Type A special permit segments must be replaced or pressure tested so that the MAOP is commensurate with the present class location within five (5) years of issuance of this special permit. There are 11 .22 miles of Type A special permit segments and of this total I 0.59 miles must be replaced and 0.63 miles must be pressure tested as listed on Attachment A. • Type A special permit segments with pipe with integrity issues as determined by Conditions 6(c) and 14 or that have not been pressure tested in accordance with 49 CFR Part 192, Subpart J to 1.25 times MAOP of this special permit must be replaced within two and one-half(2 Y2) years of the grant ofthis special permit or within two (2) years of assessment find ing. • Type B special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § I92.5(c), of 10 or fewer buildings intended for human occupancy in a "class location unit" and for which the MAOP has not been confirmed in accordance with 49 CFR § I92.6 II . There are 3 7. 78 miles of Type B special permit segments and 3.84 miles of this total must be pressure tested as listed on Attachment A. Page 2 of 10 PHMSA-2016-0004- Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> • Special permit inspection area3 - is defined as a one ( 1) mile continuous segment on both sides of the special permit segment (Type A and Type B) plus the footage in the special permit segment. Appendix A lists the boundaries for the special permit inspection area associated with each special permit segment. The special permit inspection areas total 433.71 miles of pipe as detailed in Attachment A. Subsequent to the issuance of this special permit, those special permit segments that have been pressure tested or replaced such that the MAOP has been made commensurate with the present class location as defined in 49 CFR § 192.611 would no longer be included in this special permit. This special permit allows TOP to continue to operate the pipeline segments at their current maximum allowable operating pressure (MAOP) until either replaced, hydrostatically tested, or operated in accordance with the special permit conditions. The Federal pipeline safety regulations in 49 CFR § 192.611 (a) require natural gas pipeline operators to confirm or revise the MAOP of a pipeline segment after a change in class location. A special permit would allow TOP to continue to operate each of the 192 special permit segments at their existing MAOP's despite a change in class location for the special permit specified time interval. Public Notice: On February 23, 2016, PHMSA posted a notice of this special permit request in the Federal Register (81 FR 9075). PHMSA received one ( I) public comment letter in response to the draft EA from the '·Pipeline Safety Trust" dated March 24, 2016, concerning this proposed special permit. The public comments are summarized as noted below and the referenced Findings of No Significant Impact (FONSI) can be reviewed on the docket (PHMSA-2016-0004) at www.regulations.Q.ov. • A summary of the questions asked by Pipeline Safety Trust are below: • Only PHMSA announcement of the permit noted the fact that the operator' s previous class locations had been in error. (FONSI Review: Section II) 3 Special permit inspection areas throughout these conditions include special permit segments unless specifically defined as not applicable or if the special permit segment has more stringent conditions. Page 3 of 10 PHMSA-2016-0004- Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> • The 5-year waiver to accomplish this seems unreasonably long. (FONSI Review: Section II, Footnote 2) • The Pipeline Safety Trust had several concerns with the information presented in the application and the environmental assessment. • Claimed environmental and safety benefit of the permit would occur from the elimination of the methane emissions from pipeline blowdowns; (FONSI Review: Section Vlll) • Application fails in a couple of cases to provide a complete comparison of the effects of granting or denying the permit including the impact on adjacent right-of-way owners by allowing the existing pipe to remain in- service; (FONSI Review: Section V) • In the section of Safety Risks the operator indicates that the consequence of a failure would be no different if the permit is granted or is denied, without an indication of whether denying the permit would result in a reduction of pressure or pipe replacement; ( FONSI Review: Section V) • There appears to be many segments included in the application which have never been tested in that their MAOP was determined by the Grandfather Clause (§ 192.61 9(c)). (FONSI Review: The special permit conditions would require as a minimum pressure tests for any segments that had not been pressure tested.) • The application fails to give a complete useful response to § 190.341 (c)( 4). (FONSI Review: Section II) • Rather than use the special permit process in a situation like this, PHMSA should consider entering a consent agreement with the operator with both acknowledging the operator is out of compliance. PHMSA risks regulating many individual operators by special permit, without any justification for why the regulations should not be met, in effect negating the safety factors in place under § 192.6 11 or other regulations. (FONSI Review: Section II on pages 3 and 4 of 3 1 of the FONSI notes as follows: "PHMSA considered both a Consent Agreement and Safety Order in reviewing the issues of the TGP request. Since the operator notified PHMSA of the violation, PHMSA considered a special permit with integrity management concepts in a special permit with conditions an appropriate Page 4 of 10 PHMSA-2016-0004 - Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> mechanism for this situation to maintain safety. Also, the special permit conditions would ensure the special permit segments were maintained while the segments could be upgraded with pipe replacements or pressure tests. With integrity management procedures being effective in other safety situations, PHMSA considers this to be an effective approach for the sliding mile areas with I 0 or fewer dwellings or structures for human occupancy, which is the case for over 89 percent (171 of 192 segments) of the TOP 192 special permit segments." The special permit requires replacement or pressure testing of segments with over 10 dwelling. The special permit has conditions and integrity management procedures for the special permit inspection area, 433.71 miles of pipeline.) The request letter, Federal Register notice, public comments, FONSI, and all other pertinent documents are available for review in Docket No. PHMSA-20 16-0004 in the Federal Docket Management System (FDMS) located on the internet at www.Regulations.gov. Analysis: Background: On June 29, 2004, PHMSA published in the Federal Register (69 FR 38948) the criteria it uses for the consideration of class location change waivers, now being granted through special permits. First, certain threshold requirements must be met for a pipeline section to be further evaluated for a class location change special permit. Second, the age and manufacturing process of the pipe; system design and construction; environmental, operating and maintenance histories; and integrity management program elements are evaluated as significant criteria. These significant criteria are presented in matrix form and can be reviewed in the FDMS, Docket Number PHMSA- RSPA-2004-1740 l. Third, such special permits will only then be granted when pipe conditions and the operator's integrity management program provides a level of safety equal to a pipe replacement or pressure reduction. Threshold Requirements: Each of the threshold requirements published by PHMSA in the June 29, 2004, Federal Register notice is discussed below in regards to the TGP special permit petition. Page 5 of 10 PHMSA-2016-0004- Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> 1) No pipeline segments in a class location changing to Class 4 location will be considered. This special permit request is for 192 segments on the TOP pipeline system where a class location change has occurred from Class 1 to Class 3 locations as defined in § 192.5(c) for cluster locations and segments outside the cluster (and inside the sliding mile for the class location) where an additional dwelling(s) have been identified. TOP has met this requirement. 2) No bare pipe will be considered. These TOP special permit segments are coated with an external protective coating. TOP has met this requirement. 3) No pipe containing wrinkle bends will be considered. There are no wrinkle bends in the special permit segments. TOP has met this requirement. 4) No pipe segments operating above 72% of the specified minimum yield strength (SMYS) will be considered for a Class 3 special permit. The .special permil segments operate at or below 72% SMYS. TOP has met this requirement. 5) Records must be produced that show a hydrostatic test to at least 1.25 x maximum allowable operating pressure (MAOP). TOP will pressure test any segments that do not meet this requirement through the special permit conditions. 6) In~lin inspection (ILl) must have been performed with no significant anomalies identified that indicate systemic problems. TOP will meet this requirement through the special permit conditions. 7) Criteria for consideration of class location change waiver, now being granted through special permits, published by PHMSA in the Federal Register (69 FR 38948), define a waiver inspection area (.special permit inspection area) as up to 25 miles of pipe either side of the waiver segment (special permit segment). The special permit inspection area must be inspected according to TOP's integrity management program and periodically inspected with an in~line inspection technique. The special permit inspection area extends one~mile out from either side of the special permit segments long. This additional length was used since the Type B areas that are not being replaced are locations with 10 or fewer buildings intended for human occupancy in a "class location unit" and are outside the original "cluster area'·. This special permit is contingent upon TOP's incorporation of each of the special permit segments in its written integrity management program as a ··covered segment " in a "high consequence area " (HCA) per 49 CFR § 192.903. e Page 6 of 10 PHMSA-2016-0004 - Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> Criteria Matrix: The original and supplemental data submitted by TGP for the special permit segment have been compared to the class location change special permit criteria matrix. The special permit segments fall in the probable acceptance column of the criteria matrix for all criteria except for: • Possible acceptance - pipe manufacture and pipe material • Requires substantial justification - pipe coating, Stress Corrosion Cracking Direct Assessment (SCCDA), and several leaks within 20-miles of the special permit segment. The data findings below fall within the "probable acceptance" or the "requires substantial justification" columns of the criteria matrix: 1) Pipe design and construction, including pipe manufacture, material and design stress: • TGP pipeline special permit segments have: o Pipe manufactured with the following pipe seams: low-frequency electric resistance welded, flash welded, double submerged arc welded, seamless, and electric welded pipe seams. o Pipe coatings included: coal tar enamel, hot applied wax, fusion bonded epoxy, and tape. o Pipe design stress was 72% specified minimum yield strength or lower. 2) Pipe coating, SCCDA, and several leaks: TGP will be required to conduct a stress corrosion cracking assessment (SCCDA) of the special permit segments to evaluate where the risk of stress corrosion cracking (SCC) is present. TOP will be required to implement a plan to improve cathodic protection reliability and perform inspections for sec during excavations. • To further address pipe manufacturing, material, construction, pipe coating, SCCDA, and possible pipe leak issues, this special permit will include conditions requiring TOP to treat all special permit segments as "covered segments" in an HCA per 49 CFR § 192.903. • TOP will also be required to perform ILl assessments, anomaly repairs, close interval surveys, identify any pipeline segment that may be susceptible to pipe seam issues because of the vintage of the pipe, the manufacturing process of the pipe, or other issues Page 7 of 10 PHMSA-2016-0004 - Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> and stress corrosion cracking direct assessment (SCCDA) along the entire length of the special permit inspection areas and special permit segments according to the requirements of 49 CFR § 192.929 after the grant of this special permit. • This special permit will include a condition that TGP must continue to operate each 5pecial permit segment at or below its existing MAOP. PHMSA has determined that imposing the special permit conditions will address these concerns and provide equivalent safety for these areas. Operational Integrity Compliance: PHMSA has reviewed this special permit request to ensure that integrity threats to the pipeline in the special permit segments and special permit inspection areas are addressed in the operator' s operations and management plan (O&M Plan). TGP must have a systematic program to review and remediate pipeline safety concerns. Additional operational integrity review and remediation requirements will be required by this special permit for this special permit segment class location change. The pipeline operational integrity requirements are to ensure that the operator has an ongoing program to locate and remediate safety threats. Some of these threats to integrity and safety are the pipe coating quality, cathodic protection effectiveness, anomalies in the pipe steel, and material and structures either along or near the pipeline that could cause the cathodic protection system to be ineffective. PHMSA carefully designed a comprehensive set of conditions that TGP would be required to meet in order for the special permit to be granted. Among other things, the conditions include: 1) Special permit inspection areas must be incorporated into its TOP's written integrity management program (IMP) as a "covered segment " in a "high consequence area (HCA) " in accordance with 49 CFR § 192.903. 2) A close interval survey to determine the effectiveness of the cathodic protection system must be performed within the 5pecial permit segments and special permit inspection area and all areas with inadequate cathodic protection must be remediated. Close interval surveys must be performed on a seven (7) year reassessment interval. 3) Cathodic protection reliability and inspections for stress corrosion cracking (SCC) must be performed. Page 8 of 10 PHMSA-2016-0004- Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> 4) Stress corrosion cracking surveys on the pipeline will be required to ensure that the pipe steel is not cracking due to the effects of high and near neutral pH SCC within the special permit segments and special permit inspection area. 5) Operations and maintenance (O&M) manual(s) must include the conditions of the special permit including in-line inspection (ILl), close interval inspections (CIS), remediation, and reassessment intervals. 6) Annual reports must be sent by TGP to PHMSA updating compliance. 7) Interference currents from electric transmission lines and other interfering structures in the special permit segments and special permit inspection area must be identified, controlled and mitigated by conducting surveys and installing remediation measures where required. 8) Anomalies and dents on the pipeline must be repaired based upon the special permit repair criteria for the special permit segments and special permit inspection areas. 9) Pipeline longitudinal seams within the special permit segments and special permit inspection areas must have an engineering analysis to determine if there are any threats and remediated if integrity threats are determined. l 0) Data integration of special permit condition findings and remediation must be maintained for the special permit segments and special permit inspection areas. 11 ) Long term pipeline system flow reversals that include a special permit segment must have a written plan that corresponds to those applicable criteria identified in PHMSA Advisory Bulletin (ADB-2014-04), "Guidance for Pipeline Flow Reversals, Product Changes and Conversion of Service" issued on September 18, 20 14 (79 FR 56121, Docket PHMSA-20 14-0400). 12) A senior executive officer, vice president or higher must certify in writing that TGP is complying with the special permit conditions. The special permit will contain numerous conditions to ensure TGP meets or exceeds the threshold requirements with equivalent safety and to ensure that granting the special permit will not be inconsistent with safety. Page 9 of 10 PHMSA-2016-0004- Tennessee Gas Pipeline, L.L.C. Special Permit Analysis and Findings <<>> Past Enforcement History - 2005 through Mach 28. 2016 The enforcement history is an important reflection of how TGP has been observed to follow pipeline safety regulations and is a major area of focus for the review of this application. Below is a listing of PHMSA closed enforcement matters of all types in all PHMSA Regions for TGP (OPID # 19160) from 2005 through March 28, 20 16: • Letters - of Concern or Warning - 7 matters • Notices - of Amendment or of Probable Violation - 11 matters • Orders - Corrective Action - 5 matters • Orders - Safety - 1 matter • Fines - $227,500- 100% collected • TGP had no repeat offences during this period. PHMSA has determined that imposing the special permit conditions summarized in this document will ensure that granting the special permit will not be inconsistent with safety. Findings: Based on the information submitted by TGP and PHMSA' s analysis of technical, operational and safety issues, and given the conditions that will be imposed in the special permit, PHMSA finds that granting this special permit to TGP to operate special permit segments at the current MAOP, where a change in class location has occurred from an original Class I locati on to a Class 3 location, would not be inconsistent with pipeline safety.

Special Permit Analysis and Findings <<>> PIPELINE AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION SPECIAL PERMIT FINAL ENVIRONMENTAL ASSESSMENT and FINDING OF NO SIGNIFICANT IMPACT (FONSI) Docket Number: PHMSA-2016-0004 Requested By: Tennessee Gas Pipeline Company, L.L.C. Operator ID#: 19160 Date Requested: January 11, 2016 Original Issuance Date: September 1, 2016 Effective Dates: September 1, 2016 to September 1, 2021 Code Section(s): 49 CFR §§ 192.611(a) and (d), 192.619(a), and 192.5 I. Background The National Environmental Policy Act (NEPA), 42 USC §§ 4321 — 4375, Council on Environmental Quality regulations, 40 CFR §§ 1500-1508, and DOT Order 5610.1C, require that PHMSA analyze a proposed action to determine whether the action will have a significant impact on the human environment. PHMSA analyzes special permit requests for potential risks to public safety and the environment that could result from our decision to grant or deny the request. As part of this analysis, PHMSA evaluates whether a special permit would impact the likelihood or consequence of a pipeline failure when compared to operation of the pipeline in full compliance with the Pipeline Safety Regulations. PHMSA may grant the special permit request with additional conditions or deny the request. PHMSA developed this assessment to determine the effects of our decision, if any, on the environment. Pursuant to 49 USC § 60118(c) and 49 CFR § 190.341, PHMSA may only grant special permit requests that are not inconsistent with pipeline safety. PHMSA will impose conditions in the special permit if we conclude they are necessary for safety, environmental protection, or are otherwise in the public interest. If PHMSA determines that a special permit would be inconsistent with pipeline safety or is not justified, the application will be denied. 11. Purpose and Need • Describe the purpose of the requested special permit. What will it allow the operator to do that it could not do under the existing regulations? PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 1 of 31 <<>> Pursuant to 49 CFR §190.341, Tennessee Gas Pipeline Company, L.L.C. (TGP)1 requests a special permit seeking relief from 49 CFR §§ 192.611(a) and (d), 192.619(a), and 192.5 for pipeline segments where the class location of the segment had been changed in accordance with 192.5(c), cluster rule, and where additional dwellings for human occupancy have been built within the sliding mile for class location changes outside of the cluster area. TGP found a regulatory compliance issue with past TGP procedure methodology for the determination of class location boundaries using the clustering and sliding mile criteria in 49 CFR § 192.5(c) and has updated operating procedures for usage of 49 CFR § 192.5(c), cluster rule, and the sliding mile for confirmation of maximum allowable operating pressure (MAOP). Following the purchase of TGP, Kinder Morgan, notified PHMSA of code violation issues it discovered in the TGP procedures for evaluating class locations, where pipe had been previously updated to meet class location changes from Class 1 to 3 locations in accordance with § 192.5. TGP had rnisapplied the usage of the sliding mile and cluster rule portions of § 192.5. TGP had properly conducted pipe upgrades to meet the cluster provisions in § 192.5, but had not later upgraded the pipe when a single or more dwelling were added in the sliding mile area outside the cluster area. This special permit is requested by TGP in order to postpone in some cases and waive in others cases compliance with certain regulations for the determination of class location boundaries using the clustering criteria in 49 CFR § 192.5(c). This change in clustering methodology due to misapplication of 49 CFR § 192.5(c) in TGP procedures resulted in a number of new class location units, and more specifically class 3 locations, for which pressure testing or pipe replacements are now required. This misapplication impacted 192 special permit segments2 and 49.00 miles of TGP mainline piping located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia as detailed in Attachment A for Type A and B special permit segments. These clustered class location units are identified as "Special Perrnit Segments." The proposed special permit would: 1) require the replacement or pressure testing of approximately 11.22 miles of natural gas transmission pipe (Type A3) and provides a schedule for this replacement or pressure testing work Tennessee Gas Pipeline Company, L.L.C. is owned by Kinder Morgan, Inc. 2 In the 192 segments TGP has 11.22 miles of pipe to replace or pressure test (Type A special permit segments) and other special permit segments including special permit inspection areas will implement integrity management procedures and the special permit conditions during the entire 5-year period. 3 Type A special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § 192.5(c), of more than 10 buildings intended for human occupancy in a "class location unit" and for which the maximum allowable operating pressure (MAOP) has not been confirmed in accordance with 49 CFR § 192.611(a). Type A special permit segments must be replaced so that the MAOP is commensurate with the present class location within five (5) years of issuance of this special permit. There are 21 segments and 11.22 miles of Type A special permit segments and of this total 10.59 miles must be replaced and 0.63 miles must be pressure tested as listed on Attachment A. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 2 of 31 <<>> and 2) establish enhanced integrity management procedures to maintain pipe integrity and protect both the public and the environment for the class location units in which the Special Permit Segments are located for the other 37.78 miles of pipe that are not replaced (Type B4). All of the proposed Special Permit Segments, even those not replaced or pressure tested would be treated as high consequence areas (HCAs) with the implementation of integrity management (1M) practices. In addition, TGP would comply with Conditions as provided in the terms of the special permit for all the impacted Special Permit Segments and the designated "Special Permit Inspection Aree in the proposed special permit. The Special Permit Inspection Area is defined as a one (1) mile continuous segment on both sides of the Special Permit Segment (Type A and Type B) plus the footage in the Special Permit Segment and extending 220 yards on each side of the centerline. In the instance that the pipeline does not extend a full mile either upstream from the beginning of the Special Permit Segment or downstream from the end of the Special Permit Segment, the Special Permit Inspection Area will not extend beyond the pipeline initiation or termination points. The Special Permit Inspection area will total 433.71 miles of pipe as detailed in Attachment A. In those cases where the proposed special permit would allow for the current pipeline segments to remain in place, the Conditions as prescribed in the proposed special permit would provide an additional level of safety without the impacts of excavation to remove existing pipe and install the replacement pipe. Due to the significant number of new class location segments that will require replacement or pressure testing, a special permit with IM based conditions would allow TGP a more reasonable time interval to schedule the required pipeline outages. The replacement and pressure testing of the 11.22 miles of pipe will be in accordance with the applicable sections of 49 CFR §§ 192.105, 192.611, 192.619, and Subpart J for the current class location. PHMSA found in reviewing TGP's response that a misapplication of § 192.5 had been used (under procedures in use before the Kinder Morgan acquisition) after installing upgraded pipe in a cluster area. Attachment A shows the segment locations with the number of dwellings outside of the cluster area but inside the sliding mile area. PHMSA considered both a Consent Agreement and Safety Order in reviewing the issues of the TGP request. Since the operator notified PHMSA of the violation, PHMSA considered a special permit with integrity management concepts in a special permit with conditions an appropriate mechanism for this situation to maintain safety. Also, the special permit conditions would ensure the special permit segments were maintained while the segments could be upgraded with pipe replacements or pressure tests. With integrity management procedures being effective in other safety situations, PHMSA considers this to be an effective approach for the sliding mile areas with 4 Type B special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § I92.5(c), of 10 or fewer buildings intended for human occupancy in a "class location unit" and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.611. There are 171 segments and 37.78 miles of Type B special permit segments and 3.84 miles of this total must be pressure tested as listed on Attachment A. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 3 of 31 <<>> 10 or fewer dwellings or structures for human occupancy, which is the case for over 89 percent (171 of 192 segments) of the TGP 192 special permit segments. Special permit conditions are measures to assess, evaluate, and implement measures to manage and eliminate threats to pipe integrity and public safety in areas of high consequence such as these sliding mile special permit segments. • List the regulation(s) for which the operator seeks the permit. The special permit would address the requirements of 49 CFR §§ 192.5, 192.611(a) and (d), and 192.619(a). • Describe the need for the requested special permit. How would a special permit benefit the operator? Would a special permit benefit the public? If so, please explain how. Implementation of the special permit conditions would allow TGP to avoid the replacement of 37.78 miles of pipeline. Instead, the special permit would require implementation of the special permit conditions, including enhanced integrity management procedures. The special permit would benefit the public by reducing any disruptions due to construction activities near their homes in the Special Permit Segments. • Indicate whether this is an existing or proposed pipeline. This special permit impacts only existing pipeline facilities as outlined in Attachment A. • Describe pipeline, the materials transported in the pipeline, and specift the counties and states where the affected segments of the pipeline are or would be located. The TGP pipeline transports natural gas in the pipeline segments included in the special permit that are located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia. The pipeline Special Permit Segments are generally short in length, not contiguous and are located in multiple States and counties/parishes within those states. Attachment A (Pipeline Segments and Map) outlines the specific locations — state and county — of the Special Permit Segments. 111. Alternatives • Alternative 1: Granting the Special Permit Request With Conditions ▪ Describe Alternative: Describe what PHMSA would do under this alternative. i.e. grant a permit that allows operator to schedule the replacement or pressure testing of certain pipeline segments and leave certain pipeline segment in place under added integrity measures defined PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 4 of 31 <<>> in the Conditions of the special permit and while also treating all of the identified pzpeline segments as high consequence areas. TGP proposes a special permit with conditions that includes two types of class location units (special permit segments) with clusters that impact approximately 49.00 miles of pipe. These units would be designated as either Type A or Type B special permit segments. The Type A special permit segrnents are those with more than 10 dwellings intended for human occupancy and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.611. Approximately 11.22 miles of pipe located in these special permit segments would be replaced or pressure tested. A special permit would provide a schedule for the completion of the required pipe replacements andlor pressure testing for the Type A special permit segments. Type B special permit segments that have 10 or fewer dwellings would also be subject to the Conditions of the special permit for its term. All of these special perrnit segments would be treated as high consequence areas (HCAs) under an integrity management (IM) program (49 CFR Part 192, Subpart 0) as a requirement of the special permit. Approximately 37.7g miles of pipe are located in Type B locations. The special permit would incorporate conditions (enhanced integrity management activities) to maintain pipeline integrity. All of the permit conditions are attributes of a robust IM program (49 CFR Part 192, Subpart 0). These proposed Conditions include conducting periodic: close interval surveys, cathodic protection reliability improvements, stress corrosion cracking direct assessment, running inline inspection (ILI) assessments (srnart pigs), interference current control surveys, remediating ILI findings through anomaly evaluation and repairs, pipe seam evaluations, pipe properties records review and documentation, and maintaining line-of-sight markers. Many of these proposed integrity activities are currently required in 49 CFR Part 192, Subpart 0 for an IM program to manage high consequence areas (HCAs) at specified reassessment intervals. The assessment and reassessment intervals, the level of remediation and the maintenance activities in a proposed special permit would be more stringent to maintain pipe integrity and protect both the public and the environment for the class location units in which the Special Permit Segments are located. The erthanced integrity management activities that TGP would implement as proposed special permit conditions for the pipeline segments include: PIIMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 5 of 31 <<>> 1. TGP would incorporate the pipeline segments into its written integrity management program (IMP) as a "covered segment" in a "HCA" in accordance with 49 CFR §192.903. 2. TGP would perform a close interval survey (CIS) along the entire length of pipeline segments and remediate any areas of inadequate cathodic protection no later than three (3) years after the issuance of this special permit. TGP will perform periodic CIS of the pipeline segments with a reassessment interval not to exceed seven (7) years. 3. TGP would implement a plan to improve cathodic protection reliability and perform inspections for stress corrosion cracking (SCC) during all excavations. 4. TGP would perform Stress Corrosion Direct Assessments to evaluate pipeline segments where the risk of SCC is present. 5. TGP would perform integrity assessments along the pipeline segments using appropriate assessment methods based on threats identified during the risk assessment process including both high resolution magnetic flux leakage (HR-MFL) and either HR-geometry or HR- deformation tools. TGP would reassess the pipeline segments at an interval not to exceed seven (7) years from the last assessment in accordance with 49 CFR § 192.939. 6. TGP would not let this special permit be a basis for deferring any of its assessments for HCAs in accordance with 49 CFR Part 192, Subpart O. 7. TGP would address induced alternating current (AC) from parallel electric transmission lines and other interference issues such as direct current (DC) along the pipeline segments that may affect the pipeline. 8. TGP would identify any pipeline segment that may be susceptible to pipe seam issues because of the vintage of the pipe, the manufacturing process of the pipe, or other issues. 9. TGP would install and maintain line-of-sight pipeline markers on the pipeline segments except in agricultural areas or large water crossings such as lakes where line-of-sight signage is not practical. 10. TGP would maintain data integration of all integrity findings and remediation along the pipeline segments. 11. For long term pipeline system flow reversals occurring after the effective date of the Special Permit and exceeding 90 days, TGP would prepare a written plan in accordance with Advisory Bulletin (ADB-2014-04) prior to implementing the pipeline system flow reversal through the Special Permit Segment. 12. TGP would maintain the following records for each pipeline segment: documentation showing that each Special Permit Segment has received a 49 CFR § 192.505, Subpart .1, hydrostatic test for eight (8) continuous hours and at a minimum pressure of 1.25 times MAOP, documentation of mechanical and chemical properties including pipe toughness (mill test reports) showing that the pipe in each Special Permit Segment meets the wall thickness, yield strength, tensile PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 6 of 31 <<>> strength and chemical composition of either the API Standard 5L, 5LX, or 5LS in usage at the time of manufacturing. • Alternative 2: Denial of the Request • Describe Alternative: Denial of the special permit would require the replacement and pressure testing of all the pipeline segments associated with this special permit request, which includes approximately 49.00 miles of mainline pipe. If TGP opted not to replace or pressure test the relevant segments of pipeline, 49 CFR § 192.611 requires a reduction in the pipeline maximum allowable operating pressure (MAOP).5 • Summary • A special permit allows TGP to continue to operate the pipeline segments at their current maximum allowable operating pressure (MAOP). However, according to the special permit, the pipeline segments must be replaced, hydrostatically tested, or operated in accordance with the special permit conditions. The Federal pipeline safety regulations in 49 CFR § 192.611(a) require natural gas pipeline operators to confirm or revise the MAOP of a pipeline segment after a change in class location. A special permit would allow TGP to continue to operate each of the 192 special permit segments at their existing MAOP's despite a change in class location for the special permit specified time interval. • A special permit would require TGP to replace or pressure test all segments that have over 10 dwelling in the sliding mile area that are outside the Cluster area to meet § 192.611. Segments within the sliding mile and outside the Cluster area will be allowed to implement the special permit conditions and integrity management procedures with the sliding mile and one-mile on either side of the segment. This would be similar to requiring a Class 1 location to implement integrity management procedures (49 CFR Part 192, Subpart 0) for all mileage, whether it meets the definition of a high consequence area or not. • Background on Class Location Special Permits: On June 29, 2004, PHMSA published in the Federal Register (69 FR 38948) the criteria it uses for the consideration of class location change waivers, now being granted through special permits. First, certain threshold requirements must be met for a pipeline section to be further evaluated for a class location change special permit. Second, the age and manufacturing process of the pipe; system design and construction; environmental, operating and maintenance histories; and integrity management program elements are evaluated as significant criteria. These significant criteria are presented in matrix form and can be reviewed in the FDMS, Docket 5 These regulatory options are specified in 49 CFR § 192.611 Change in class location: Confirmation or revision of maximum allowable operating pressure. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 7 of 31 <<>> Number PHMSA—RSPA-2004-17401. Third, such special permits will only then be granted when pipe conditions and the operator's integrity management program provides a level of safety equal to a pipe replacement or pressure reduction. IV. Site Description • Describe the environment in the vicinity of the portions of pipeline that would be subject to the special permit. The pipeline segments are generally short in length, not contiguous and are located in multiple States and counties/parishes within those states. Attachment A outlines the specific locations — state and county — of the proposed Special Permit Segments. Due to the number of Special Permit Segments and the multiple locations and topography of each proposed location varies.6 The pipeline segments identified as part of this special permit that include approximately 49.00 miles of mainline pipe. TOP proposes a special permit that includes two types of class location units (units) with clusters that impact approximately 49.00 miles of pipe. These units would be designated as either Type A or Type B special permit segments. The Type A special permit segments are those with more than 10 dwellings intended for human occupancy and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.611. Approximately 11.22 miles of pipe located in these units would be replaced or pressure tested. A special permit would provide a schedule for the completion of the required pipe replacements and/or pressure testing for the Type A units. Type B special permit segments that have 10 or fewer dwellings would also be subject to the Conditions of the special permit for its term. All of these special permit segments would be treated as high consequence areas (HCAs) under an integrity management (1M) program (49 CFR Part 192, Subpart 0) as a requirement of the special permit. V. Environmental Impacts of Each Alternative In this section, you must describe the different alternatives for agency action on your special permit request. Describe at least two alternatives. • Alternative 1: Granting the Special Permit Request With Conditions 6 The TGP pipeline facilities described in Attachment A, which include the Special Perrnit Segments, are regulated by the Federal Energy Regulatory Commission (FERC). Prior to approving natural gas pipeline siting, FERC analyzes the environmental impacts of siting, construction, and operation along the proposed pipeline routes. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 8 of 31 <<>> • Describe Alternative: Describe what PHMSA would do under this alternative. i.e. grant a permit that allows operator to schedule the replacement or pressure testing of certain pipeline segments and leave certain pipeline segrnent in place under added integrity measures defined in the Conditions of the special permit and while also treating all of the identified pipeline segments as high consequence areas.. The special permit includes two types of class location units (units) with clusters that impact approximately 49.00 miles of pipe. These units would be designated as either Type A or Type B special permit segments. The Type A special permit segments are those with more than 10 dwellings intended for human occupancy and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.611. Approximately 11.22 miles of pipe located in these units would be replaced or pressure tested. The special permit provides for a schedule for the completion of the required pipe replacements and/or pressure testing for the Type A special permit segments. Type B special permit segments that have 10 or fewer dwellings would also be subject to the Conditions of the special permit for its term. All of these special permit segments would be treated as high consequence areas (HCAs) under an integrity management (IM) program (49 CFR Part 192, Subpart 0) as a requirement of the special permit. The special permit would incorporate a minimum of 12 enhanced integrity management activities described above. All of the proposed special permit conditions are attributes of a robust IM program. These Conditions include conducting periodic: close interval surveys, cathodic protection reliability improvements, stress corrosion cracking direct assessment, running inline inspection (ILI) assessments (smart pigs), interference current control surveys, remediating ILI findings through anomaly evaluation and repairs, pipe seam evaluations, pipe properties records review and documentation, and maintaining line-of-sight markers. All of these integrity activities are currently required in 49 CFR Part 192 for either normal operational activities or within an IM program at some reassessment intervals. The assessment and reassessment intervals, the level of remediation and the maintenance activities in the special permit are more stringent to maintain pipe integrity and protect both the public and the environment for the class location units in which the pipe segments are located. • Safety Risks: special permit. Describe what, i f any, safety risks would result i f the regulation were waived as compared to the safety risks in the absence of a Sections 192.5, 192.611(a) and (d), and 192.619(a) are in the gas pipeline regulations to maintain the safety of the pipeline based upon maximum PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 9 of 31 <<>> allowable operating pressure (MAOP), population (Class locations) and population growth along the pipeline. Class locations are based upon the population (dwellings for human occupancy) within a "class location unit" which is defined as an onshore area that extends 220 yards on either side of the centerline of any continuous 1-mile of pipeline. These locations are determined by surveying the pipeline for population growth. The more conservative safety factors are required as dwellings for human occupancy (population growth) increases near the pipeline. Pipeline operators must conduct surveys and document population growth within 220 yards on either side of the pipeline. A higher population along the pipeline may trigger any of the following for the pipeline segment with the higher population: a reduced MAOP, a new pressure test at a higher pressure, or new pipe with either or both heavier walled or higher grade pipe to protect against integrity risks to occupants along the pipeline segment. The proposed special permit enhanced integrity management conditions would be designed to identify and mitigate integrity issues that could threaten the pipeline segment and cause failure. The effect of the monitoring and maintenance requirements in the proposed special permit conditions will ensure the integrity of the pipe and protection of the population living near the pipeline segment to a similar degree of a lower MAOP, new pressure test, or a thicker walled or higher grade pipe without the enhanced IM protections. If PHMSA were to deny the special permit request, TGP would be required to reduce the pressure in the affected pipeline segments. In this situation, the consequences, and the PIR (a separate question and response) would be less than if the permit is granted because the pipeline would operate at a higher operating pressure under the special permit. In most cases a pressure reduction would be approximately 20 percent of current operating pressures. This reduction would be the difference in a Class 1 versus Class 2 location design safety factor (0.72 versus 0.60). A pressure reduction would reduce gas flow volumes to customers. The safety risk with respect to this request for a special permit focuses on maintaining the integrity of the pipeline and on the risk it poses to the increased population to mitigate a failure of this pipeline. Granting this special permit does not increase the potential impact radius (PIR (the radius of a circle within which the potential failure of a pipeline could have significant impact on people or property)) of the pipeline. However, the risk from the increased human population around the pipeline would be mitigated through IM procedures. PIR is the radius of a circle within which the potential failure of a pipeline could have significant impact on people or property. The current PIR's for these pipeline segments are calculated using Section 3 of ASME PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONS1 Page 10 of 31 <<>> B31.8S-2004, "Managing System Integrity of Gas Pipelines, incorporated by reference by 49 CFR §192.903. The formula and resulting calculation are as follows: (see Attachment D for a more in depth discussion of PIR). r = radius of the circular area in feet surrounding the point of failure, otherwise known as the PIR d nominal diameter of the pipeline in inches; p = pipeline segment's maximum allowable operating pressure (MAOP), psig Note: the coefficient for natural gas is 0.69. This number will vary for other gases depending on their heat of combustion. r = 0.69 * d * TGP proposes to increase integrity management inspections for pipeline segments adjacent to the Special Permit Segments, which would lower the risk in areas beyond the special permit. TGP proposes to conduct IM type procedures (proposed Conditions in the Special Permit) on the Special Permit Inspection Areas (433.71 miles) as defined in the Special Permit. TGP would implement the proposed condition in Type B Special Permit Inspection Areas for the duration of the special permit, and in Type A Special Permit Inspection Areas until the Special Permit Segment has been replaced with new pipe. Special permit conditions would include the enhanced IM protections in Section III — Alternative , Items 1 through 12, which would require conducting periodic: close interval surveys, cathodic protection reliability improvements, stress corrosion cracking direct assessment, running inline inspection (ILI) assessments (smart pigs), interference current control surveys, remediating ILI findings through anomaly evaluation and repairs, pipe seam evaluations, pipe properties records review and documentation, and maintaining line-of-sight markers to identify, assess, and mitigate threats to the integrity of the pipeline both for Special Permit Segments and the larger Special Permit Inspection Area. The special permit conditions will require TGP to conduct hydrostatic pressure tests on any Type B special permit segments that have not been pressure tested to 1.25 times MAOP or greater to be pressure tested. None of the special permit segments have MAOPs established using 192.619(c) Grandfather Clause, which operate above 72 percent pipe design factor or without a prior pressure test for a Class 1 location. Requiring most of the special permit conditions to be applicable to the Special Permit Inspection Areas, which extends a mile out from either side of the special permit segments, larger areas of the pipeline will be assessed and remediated for threats to the integrity of the pipeline than a PIR that is PIIMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 11 of 31 <<>> used to establish a high consequence area (HCA). Attachment A gives the integrity management PIR for each TGP pipeline segment, which in all eases is less 760 feet or less and is much less than the l-mile length used to establish the Special Permit Inspection Area. Performance of the Conditions in the special permit provides an equivalent or greater level of safety for the public and environment; and imposes no additional safety risks as a result of the waived regulation. As already noted, all of the pipeline segments included under the special perrnit would be treated as HCAs with the additional risk analysis and remedial activities associated with this designation. The special permit also includes a number of conditions that address potential safety risks. Among these are incorporation of these segments into the Kinder Morgan Integrity Management Program, additional close interval corrosion surveys, implementation of a cathodic protection reliability improvernent plan, a more comprehensive stress corrosion cracking direct assessment program, an in-line inspection (ILI) program with intervals not to exceed seven years, anomaly evaluation and repair meeting more stringent criteria, additional testing and remediation of interference currents caused by induced alternating current sources, pipe seam evaluations, criteria for the identification of pipe properties, installation of line-of-sight markers and the integration of all inspection and remediation data. This comprehensive list of additional risk related Conditions incorporated in the special permit is intended to provide for a significant added level of safety for the existing pipeline segments. • Would operation under a special permit change the risk of rupture or failure? Operation under the special permit would not be expected to have an impact on the risk of failure or rupture as the operating conditions of the pipeline segments have not changed. Segments in the special permit would have inspections at intervals similar to IM program intervals, which would maintain the integrity of the pipe segments over the life of the special permit. • If a failure occurred, would consequences and spill or release volumes be different if PHMSA granted the permit? Increase risk, decrease risk no change? The consequences of any spill or release would not be impacted as a result of the special permit and the potential for such an event is expected to be less likely with the added safety programs noted above. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 12 of 31 <<>> a Would the Potential Impact Radius (PIR) of a rupture change under the special permit? Would more people be affected by a failure ifwe granted the permit? The PIR as calculated in accordance with 49 CFR § 192.903 would not change under the special permit since maximum operating pressure and pipe diameter will not change, thus there would be no additional impact on the public. • Would operation under the special permit have an effect on pipeline longevity or reliability? Would there be any life cycle or maintenance issues? Operation under the Special Permit Conditions that provide an additional level of safety is expected to have a positive impact on pipeline longevity and reliability. TGP does not anticipate any deleterious life cycle or maintenance issues related to operation of the pipeline with the special permit and conditions based upon IM type procedures. Implementation of the proposed conditions in the special permit provides an equivalent level of safety for the public and environment; and imposes no additional safety risks as a result of the waived regulation. As already noted, all of the pipeline segments included under the special permit would be replaced with new pipe (Type A) or treated as HCAs with the additional risk analysis and remedial activities associated with this designation (Type B). The special permit also includes a number of proposed Special Permit Conditions that would address potential safety risks. Among these are incorporation of these segments into the Kinder Morgan Integrity Management Program, additional close interval corrosion surveys, implementation of a cathodic protection reliability improvement plan, a more comprehensive stress corrosion cracking direct assessment program, an in-line inspection (ILI) program with intervals not to exceed seven years, anomaly evaluation and repair meeting more stringent criteria, additional testing and remediation of interference currents caused by induced alternating current sources, pipe seam evaluations, criteria for the identification of pipe properties, installation of line-of-sight markers and the integration of all inspection and remediation data. This comprehensive list of additional risk related conditions incorporated in the special permit is intended to provide for a significant added level of safety for the existing pipeline segments. • Environmental Impacts: Explain how operation under the special permit would impact the environment as compared to the status quo in the absence of a special permit. either positively, negatively, or not at all. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 13 of 31 <<>> Approval of the special permit would have a positive impact for those units that do not require pressure testing or replacement, since TGP's activities would have negligible, if any, environmental impact. TGP would avoid disturbing the right of way of property owners except for the additional inspections that may be required to satisfy the conditions of the special permit such those related to the Integrity Management Program for HCAs, additional SCCDA verification digs, and potential anomaly evaluations/repairs. While the special permit would avoid the full replacement of affected pipe, the proposed special permit conditions require monitoring and maintenance that could lead to excavations and repair or replacement of some pipe. TGF will evaluate the potential environmental consequences and affected resources of land disturbances and water body crossings caused by construction activities (including adding, modifying, replacing or removing any facility) for the related environmental permits associated with any TGP activity. This evaluation is outlined in Kinder Morgan's Operating and Maintenance Procedure (O&M) 1205: Land Disturbance, Construction, and Environmental Permits, and referenced forms and procedures, which requires obtaining the required permits prior to conducting any construction activity. These procedures ensure that all activities resulting in land disturbances or construction of new or modified facilities comply with the requirement to obtain all applicable environmental permits and other applicable environmental authorizations. These procedures contain information required to identify activities subject to Federal, State, and Local environmental authorizations related to the work and to obtain those authorizations. The procedures require a review by TGP Environmental Services staff prior to the start of work, incorporation of environmental requirements into the project implementation, and ensuring outstanding (environmental) requirements are incorporated into facility operation. If the activities do not qualify under the requirements of the Federal Energy Regulatory Commission (FERC) "General Rules and Regulations" Section 2.55(a) or 2.55(b) facilities or the blanket certificate, TGP will pursue authorization in accordance with Section 7 of the Natural Gas Act. • Explain whether and how operation under the special permit would impact each of the environmental resources set out in the Site Description portion of this document: land use planning, surface waters (including wetlands), drinking water, soils and vegetation, wildlife habitats (including fisheries), cultural resources, socioeconomics, Native Americans, etc. ? Focus on environmental aspects that are impacted Are there any geologic hazards? Would any of these impacts be significant? PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 14 of 31 <<>> As already noted, this special permit involves pipeline facilities at various locations. Each of the environmental resources potentially impacted that are listed would be addressed in accordance with the applicable Kinder Morgan procedures and FERC requirements. Although the environmental impacts are not expected to be significant it must be kept in mind that for those units requiring pressure testing or pipe replacements (Type A) there will be excavation related activities, along with water sourcing and water disposal issues at a minimum. These impacts will occur whether or not the Special Permit is granted. For the Type B segments, approval of the special permit request would avoid disturbance to the environment, public roadways, businesses and homes since pipe replacement would not be required at this time. PHMSA may require pipe replacement at a later date if integrity issues are found with the pipe or if the segment grows to over 10 dwellings for human occupancy in the sliding mile length that is outside the upgraded Cluster area. • Discuss direct, indirect and cumulative impacts. The majority of the pipeline segments addressed by this special permit have been buried and undisturbed for many years. The current pipeline cover has therefore returned to its original state in most cases. Any activity related to pressure testing or pipe replacement will be temporary in nature and the pipeline right of way would be restored in accordance with required environmental regulations. Direct, indirect, or cumulative impacts associated with activities related to the special permit would not be significant. • Briefly summarize environmental aspects that will not be impacted. Explain why these resources won't be impacted. As already noted, those pipeline segments that do not require pressure testing or pipe replacements will be operated in nearly the same manner as they are currently. The special permit would allow approximately 37.78 miles of Type B7 Special Permit Segments to remain in their current state and not require excavation or disruption of landowner activities. Unless localized excavations are needed, right of way activities (such as additional pipeline markers) may increase in frequency due to the special permit conditions, but it is anticipated that there would be a very minimal added environmental impact related to those activities. 7 Type B special permit segments total 37,78 miles of pipe of which 3.84 miles will require pressure testing. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 15 of 31 <<>> All ILI Tool inspections to determine any pipeline integrity issues due to corrosion or third party damage would be propelled down the pipeline by gas flow volumes pushing ILI tools through the pipeline segment. Other IM inspections would be performed along the pipeline segment right of way. a Special Permit Conditions: [Describe the additional safety measures you propose to implement in lieu of compliance with the regulations. You may reference information already provided in your special permit request, as relevant.] The Conditions related to this special permit are described in detail in the special permit. • [Explain whether and how each of these safely measures addresses the safety risks and environmental impacts, i f any, of granting the permit.] Each of the special permit conditions have been included and designed to address the anticipated safety risks and environmental impacts of the TGP pipeline segments covered by the proposed special permit. • [Explain whether, even with the safety measures you propose, there would be any safety risks or environmental impacts beyond those that would exist in the absence of a special permit.] There are currently no known safety risks or environmental impacts that are not addressed by the special permit conditions. The pipeline segments included in the proposed special permit are currently operating safely and are expected to continue to perform in that same manner. • [Would implementation of the safe0) measures themselves have any environmental impacts? If so, would they be significant? Discuss direct, indirect and cumulative impacts.] The additional safety measures provided by the proposed special permit conditions are not expected to have any significant environmental impacts other than the potential issues already noted that are related to the required pressure tests and/or pipe replacements. Please see Section III, Site Description, which outlines the environmental review process followed by TGP prior to any excavation being implemented. TGP follows a rigorous procedural process as dictated by federal, state and local entities to PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 16 of 31 <<>> assure compliance with all environmental regulations and requirements as outlined in this prior section. PHMSA has reviewed the Part 192 requirements for replacing the pipeline and the conditions of the special permit including integrity management practices and considers both to have similar environmental and right-of-way impacts. These impacts will be mitigated by following the FERC procedures outlined in Section V. • Alternative 2: Denying the Special Permit Request and Requiring Full Compliance with 49 CFR Part 192. • Describe Alternative: Applicant would be required to comply with 49 CFR §§ 192.5, 192.611(a) and (d), and 192.619(a). TGP would be required to replace existing pipe with heavier walled pipe. Denial of the permit and full adherence to the Code would afford the protections described above that are associated with either: a lower MAOP, new pressure test, or heavier walled or higher grade pipe. Denial of the special permit would mean for most of these pipeline segments that the enhanced integrity management portions of a special permit conditions would probably not be implemented. Denial of the special permit would require excavation to remove existing pipe, acquiring environmental permits where necessary, and pressure testing of the replacement pipeline segments. This action would create an impact to vegetation, soils and possibly waterways due to the excavation, use of public roadways, and the impacted right of way during construction. TGP will evaluate the potential environmental consequences and affected resources of land disturbances and water body crossings caused by construction activities (including adding, modifying, replacing or removing any facility) for the related environmental permits associated with any TGP activity. This evaluation is outlined in Kinder Morgan's Operating and Maintenance Procedure (O&M) 1205: Land Disturbance, Construction, and Environmental Permits, and referenced forms and procedures, which requires obtaining the required permits prior to conducting any construction activity. These procedures ensure that all activities resulting in land disturbances or construction of new or modified facilities comply with the requirement to obtain all applicable environmental permits and other applicable environmental authorizations. These procedures contain information required to identify activities subject to Federal, State, and Local environmental authorizations related to the work and to obtain those authorizations. The procedures require a PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 17 of 31 <<>> review by TGP Environmental Services staff prior to the start of work, incorporation of environmental requirements into the project implementation, and ensuring outstanding (environmental) requirements are incorporated into facility operation. If the activities do not qualify under the requirements of 2.55(a) or 2.55(b) facilities or the blanket certificate, TGP will pursue authorization in accordance with Section 7 of the Natural Gas Act. VI. Public Comments In this section, PHMSA is summarizing public comments received for this proposed special permit. • PHMSA received one public comment letter in response to the draft EA and draft special permit from "Pipeline Safety Trusr dated March 24, 2016, concerning this proposed special permit. Questions asked by Pipeline Safety Trust are answered throughout this document and the letter can be reviewed on the docket (PHMSA-2016-0004) at www.regulations.gov. A summary of the questions asked by Pipeline Safety Trust are below: • Only PHMSA announcement of the perrnit noted the fact that the operators previous class locations had been in error. (FONSI Review: Section II) ▪ The 5-year waiver to accomplish this seems unreasonably long. (FONSI Review: Section II, Footnote 2) • The Pipeline Safety Trust had several concerns with the information presented in the application and the environmental assessment. • Claimed environmental and safety benefit of the permit would occur from the elimination of the methane emissions from pipeline blowdowns; (FONSI Review: Section VIII) • Application fails in a couple of cases to provide a complete comparison of the effects of granting or denying the permit including the impact on adjacent right-of-way owners by allowing the existing pipe to remain in-service; (FONSI Review: Section V) • In the section of Safety Risks the operator indicates that the consequence of a failure would be no different if the permit is granted or is denied, without an indication of whether denying the permit would result in a reduction of pressure or pipe replacement; ( FONSI Review: Section V) • There appears to be many segments included in the application which have never been tested in that their MAOP was determined by the Grandfather Clause (§ 192.619(c)). (FONSI Review: The special permit conditions would require as a minimum pressure tests for any segments that had not been pressure tested. Four segments have never been pressure tested and are listed on Attachment A as KM segments 103, 181, 310, and 311. These segments will be either pressure tested or replaced.) PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 18 of 31 <<>> • The application fails to give a complete useful response to § 190.341(c)(4). (FONSI Review: Section II) • Rather than use the special permit process in a situation like this, PHMSA should consider entering a consent agreement with the operator with both acknowledging the operator is out of compliance. PHMSA risks regulating many individual operators by special permit, without any justification for why the regulations should not be met, in effect negating the safety factors in place under § 192.611 or other regulations. (FONSI Review: Section II - The special permit requires replacement or pressure testing of segments with over 10 dwelling. The special permit has conditions and integrity management procedures for the special permit inspection area, 433.71 miles of pipeline.) VII. Reporting In this section, you must describe the different reporting activities to other agencies and reporting basis (such as quarterly or annually) of right-of-way activities that require permits for this proposed special permit. • TGP will submit an annual report to the FERC pursuant to Section 2.55(b) concerning replacement activities performed in the prior calendar year that were exempt from the advance notification requirements as specified in Section 2.55(b)(2). The following items are provided to FERC: • (i) A brief description of the pipeline facilities to be replaced (including pipeline size and length, compression horsepower, design capacity, and cost of construction); • (ii) Current U.S. Geological Survey 7.5-minute series topographic maps showing the location of the facilities to be replaced; and • (iii) A description of the procedures to be used for erosion control, revegetation and maintenance, and stream and wetland crossings. • TGP will submit an annual report of Blanket Certificate Activities performed pursuant to Sections 157.208, and 385.2011 of the FERC regulations. The following information will be provided pursuant to the applicable blanket certificate regulation: • Section 157.208 (Construction, acquisition, operation, replacement, and miscellaneous rearrangement of facilities): • (1) A description of the facilities installed pursuant to this section, including a description of the length and size of pipelines, compressor horsepower, metering facilities, taps, valves, and any other facilities constructed; • (2) The specific purpose, location, and beginning and completion date of construction of the facilities installed, the date service commenced, and, if applicable, a statement indicating the extent to which the facilities were jointly constructed; PHMSA-2016-000-I Tennessee Gas Pipeline, L.L.C. FONSI Page 19 of 31 <<>> • (3) The actual installed cost of each facility item listed pursuant to paragraph (e)(1), separately stating the cost of materials and labor as well as other costs allocable to the facilities; • (4)(i) A description of the contacts made, reports produced, and results of consultations which took place to ensure compliance with the Endangered Species Act, the National Historic Preservation Act and the Coastal Zone Management Act; • (ii) Documentation, including images, that restoration of work areas is progressing appropriately; • (iii) A discussion of problems or unusual construction issues, including those identified by affected landowners, and corrective actions taken or planned; and • (5) For acquisitions of facilities: • (i) A statement referencing the date of issuance, docket number and title of the proceeding for any certificate issued by the Commission authorizing the facilities acquired; and • (ii) The amounts recorded in the accounts of the vendor (seller or lessor) that apply to the facilities acquired and the accumulated provisions for depreciation, depletion, and amortization. VIII. Finding of No Significant Impact (FONSI) PHMSA has carefully analyzed the safety and environmental risks associated with the above alternatives. PHMSA believes there are minimal differences in environmental benefits from Alternative 1 (Granting the Special Permit Request With Conditions) or Alternative 2 (Denial) in eliminating methane emissions. Some methane emissions will occur from blowdowns in anticipation of hydrotesting or pipe replacement for either alternative. TGP must use operating practices to minimize gas volumes in the pipe prior to segment blowdown for either Alternative 1 or 2. PHMSA will require Type A special permit segments8 to be replaced with new upgraded pipe in accordance with 49 CFR §§ 192.611(a) and 192.619(a) requirements for a Class 3 location or pressure tested so that the MAOP is commensurate with the present class location. Type B special permit segments9 will be required to implement IM procedures and the conditions in the special permit. g Type A special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § 192.5(c), of more than 10 buiklings intended for human occupancy in a "class location unit" and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.61(a). 9 Type B special permit segments include those special permit segments where there is a cluster, as described in 49 CFR § 192.5(c), of 10 or fewer buildings intended for human occupancy in a "class location unit" and for which the MAOP has not been confirmed in accordance with 49 CFR § 192.611. PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. FONSI Page 20 of 31 <<>> PHMSA will grant TGP a special permit with conditions as outlined in Alternative 1 and Reporting sections above. TGP will implement additional special permit conditions to maintain safety and will follow the FERC and any other applicable Federal, state, and local regulations for evaluating and mitigating the potential environmental consequences and affected resources of land disturbances and water body crossings caused by construction activities (including adding, modifying, replacing or removing any facility) for the related environmental permits associated with any TGP activity. PHMSA has imposed conditions on this special permit designed to protect the public, property, and the environment from the risk of a pipeline leak or failure. These conditions are designed to ensure that the likelihood of a leak or failure is not greater than it would be in the absence of the special permit. Therefore, we believe there are no significant environrnental impacts associated with the issuance of a special permit to TGP. The TGP special permit conditions will maintain safety and the environment for the 49.00 miles of pipe in the special permit segments until replaced with upgraded pipe or pressure tested and will require integrity management concepts to be implemented for 433.71 miles of special permit inspection areas.

In the first annual report, TGP must describe the estimated economic benefits of the special permit including both the capital and operational costs avoided from not replacing the pipe and the estimated incremental operational costs of any inspection program requirements of the special permit for the 5-year grant period that are not already being conducted by TGP through their operational procedures. In the first annual report, TGP must describe whether the public benefits from enemy availability. This should address the benefits of any avoided disruptions as a consequence of pipe replacement and the benefits of maintaining system capacity. 12) Interference Currents Control: TGP must address induced alternating current (AC) from parallel electric transmission lines and other interference issues such as direct current (DC) in the special permit inspection areas that may affect the pipeline. An induced AC or DC program and remediation plan to protect the pipeline from corrosion caused by stray currents must be in place within one (1) year of the date of this special permit. a) At least once every seven (7) years not exceeding 90 months, TGP must perform an engineering analysis on the effectiveness of the AC and DC mitigation measures and must evaluate any AC interference between 20 and 50 Amps per meter squared. In evaluating such interference, TGP must integrate AC interference data with the most recent ILI results to determine remediation measures. Any AC interference between 20 and 50 Amps per meter squared must be remediated within six (6) months of the finding. If TGP does not remediate AC interference between 20 and 50 Amps per PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C. Special Permit Page 11 of 33 <<>> b) c) d) meter squared, TGP must provide an engineering justification for not remediating such interference to the appropriate PHMSA OPS Region Director, who may accept or reject the justification and require remediation. In special permit inspection areas with co-located high voltage alternating current (HVAC) power lines, TGP must take interference readings (continuous 24-hour recordings) during the calendar quarter of the known or anticipated highest voltage reading. If there are any significant increases to the amount of electricity/current flowing in any co-located high voltage altemating current (HVAC) power lines, such as from additional generation, a voltage up-rating, additional lines, or new or enlarged substations, TGP must perform an AC mitigation survey along the entire co-located pipeline special permit inspection area right of way within six (6) months of any such change. Within six (6) months of the engineering analysis, TGP must remediate any AC interference greater than 50 Amps per meter squared. Remediation means the implementation of performance measures including, but not limited to, additional grounding along the pipeline to reduce interference currents. Any DC interference that results in CP levels that do not meet the requirements of 49 CFR Part 192, Subpart I, must be remediated within six (6) months of this evaluation. If environmental permitting or right-of-way factors beyond TGP control prevent the completion of rernediation within six (6) months of the interference evaluation, remediation must be completed as soon as practicable and a letter justifying the delay and providing the anticipated date of completion must be submitted to the appropriate PHMSA OPS Region Director no later than one (1) month prior to the end of the six (6) months completion date. Any extended evaluation and remediation schedules submitted to PIIMSA from TGP must receive a "no objection" from the appropriate PHMSA OPS Region Director. 13) Anomaly Evaluation and Repair: a) General: TGP must account for ILI tool tolerance and corrosion growth rates in scheduled response times and repairs and document and justify the values used. TGP must demonstrate ILI Tool tolerance accuracy for each ILI Tool run by usage of PHMSA-2016-0004 Tennessee Gas Pipeline, L.L.C.

Special Permit Page 13 of 33 <<>> Definitions 1. Plain Dent — Dent without metal loss, crack or stress riser. 2. Immediate Response — Reduce pressure to 80% of recent maximum pressure. hmnediate dents require an immediate pressure reduction and / or restriction and examination and remediation as required in conformance with TGP requirements within five (5) calendar days from the date of discovery. If the remediation cannot be met according to the response schedule, a technical justification must be prepared that explains the reasons why the remediation cannot be met according to the schedule and indicate how the changed schedule will not jeopardize public safety. Any extended response schedules must be submitted to PHMSA from TGP within 14 days of pressure reduction after discovery and must receive a "no objection" from the appropriate PHMSA OPS Region Director. 3. Scheduled Response — Schedule excavation within an appropriate time frame based on the opinion of the TGP SME (not to exceed 365 days for special permit segments and 730 days for special permit inspection areas). 4. 5. 6.

TGP requests that PHMSA waive compliance from 49 Code of Federal Regulations (CFR) 192.611(a) and (d), 192.619(a), and 192.5 for 162 segments and 36.901 miles of natural gas transmission pipeline segments. Pipeline System Affected: This special permit renewal request applies to 162 special permit segments and 36.901 miles of natural gas transmission pipeline operated by TGP and located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas, and West Virginia where a change has occurred from an original Class 1 location to a Class 3 location. 1 Tennessee Gas Pipeline Company LLC is owned by Kinder Morgan, Inc. PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 1 of 20 <<>> This special permit allows TGP to continue to operate the 162 special permit segments at their current maximum allowable operating pressure (MAOP). Special Permit Request: TGP submitted an application to PHMSA on March 4, 2021, for a special permit renewal seeking relief from the Federal pipeline safety regulations in 192.611(a) and (d), 192.619(a), and 192.5 for 162 special permit segments and 36.901 miles of natural gas transmission pipeline. The special permit segments are located in the states of Kentucky, Louisiana, Mississippi, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and West Virginia. Special permit segments are divided into two (2) categories: Type A special permit segments and Type B special permit segments. • Type A special permit segments include those special permit segments as described in Attachment A - Type A Special Permit Segments and Inspection Areas, where there is a cluster, as described in 49 CFR 192.5(c), of more than 10 buildings intended for human occupancy in a “class location unit” and for which the MAOP has not been confirmed in accordance with 49 CFR 192.611(a) or where the pipe installed has been identified to have a seam type or manufacturer type that is problematic for maintaining pipeline integrity. Type A special permit segments total approximately 10.192 miles (53,813.09 feet) of pipe in this proposed special permit renewal. Type A special permit segments must meet Condition 1(d) and Conditions 8(b)(i) and (c) of the Special Permit Conditions. • Type B special permit segments include those special permit segments where there is a cluster, as described in 49 CFR 192.5(c), of 10 or fewer buildings intended for human occupancy in a “class location unit” and for which the MAOP has not been confirmed in accordance with 49 CFR 192.611. Type B special permit segments total approximately 26.348 miles (139,115.00 feet) of pipe as described in Attachment A – Type B Special Permit Segments and Inspection Areas. • Special permit inspection areas are defined as a one (1) mile continuous segment on both sides of the special permit segment (Type A and Type B) plus the footage in the special permit segment. Attachment A lists the boundaries for the special permit inspection area associated with each special permit segment. PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 2 of 20 <<>> Subsequent to the issuance of this special permit, those special permit segments that have been pressure tested or replaced such that the MAOP has been made commensurate with the present class location as defined in 49 CFR 192.611 would no longer be included in this special permit. This special permit allows TGP to continue to operate the pipeline segments at their current maximum allowable operating pressure (MAOP) until either replaced, hydrostatically tested, or operated in accordance with the special permit conditions. The Federal pipeline safety regulations in 49 CFR 192.611(a) require natural gas pipeline operators to confirm or revise the MAOP of a pipeline segment after a change in class location. A special permit would allow TGP to continue to operate each of the 162 special permit segments at their existing MAOP’s despite a change in class location for the special permit specified time interval. Public Notice: On May 27, 2022, PHMSA posted a notice of this special permit request in the Federal Register (87 FR 32227) with a closing date of June 27, 2022. PHMSA has reviewed all public comments received for Docket Number PHMSA-2016-0004. PHMSA received public comments concerning this special permit request that have been addressed in the Final Environmental Assessment and Finding of No Significant Impact (FEA and FONSI). The TGP special permit application letter, Federal Register notice, Final Environmental Assessment, Finding of No Significant Impact, and all other pertinent documents are available for review in Docket No. PHMSA-2016-0004 in the Federal Docket Management System (FDMS) located at www.Regulations.gov. Analysis: Background: On June 29, 2004, PHMSA published in the Federal Register (69 FR 38948) the criteria it uses for the consideration of class location change waivers, now being granted through special permits. First, certain threshold requirements must be met for a pipeline section to be further evaluated for a class location change special permit. Second, the age and manufacturing process of the pipe; system design and construction; environmental, operating and maintenance histories; and integrity management program elements are evaluated as significant criteria. These significant criteria are presented in matrix form and can be reviewed in the FDMS, Docket PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 3 of 20 <<>> Number PHMSA–RSPA-2004-17401. Third, such special permits will only then be granted when pipe conditions and the operator’s integrity management program provides a level of safety equal to a pipe replacement or pressure reduction. Threshold Requirements: Each of the threshold requirements published by PHMSA in the June 29, 2004, Federal Register notice is discussed below in regards to the TGP special permit petition. 1) No pipeline segments in a class location changing to Class 4 location will be considered. This special permit request is for 162 special permit segments on the TGP pipeline system where a class location change has occurred from Class 1 to Class 3 locations as defined in49 CFR 192.5(c) for cluster locations and segments outside the cluster (and inside the sliding mile for the class location) where an additional dwelling(s) have been identified. TGP has met this requirement. 2) No bare pipe will be considered. These TGP special permit segments are coated with an external protective coating. TGP has met this requirement. 3) No pipe containing wrinkle bends will be considered. There are no wrinkle bends in the special permit segments. TGP has met this requirement. 4) No pipe segments operating above 72% of the specified minimum yield strength (SMYS) will be considered for a Class 3 special permit. The special permit segments operate at or below 72% SMYS. TGP has met this requirement. 5) Records must be produced that show a hydrostatic test to at least 1.25 x maximum allowable operating pressure (MAOP). TGP will pressure test any segments that do not meet this requirement through the special permit conditions. 6) In-line inspection (ILI) must have been performed with no significant anomalies identified that indicate systemic problems. TGP will meet this requirement through the special permit conditions. 7) Criteria for consideration of class location change waiver, now being granted through special permits, published by PHMSA in the Federal Register (69 FR 38948), define a waiver inspection area (special permit inspection area) as up to 25 miles of pipe either side of the waiver segment (special permit segment). The special permit inspection area must be inspected according to TGP’s integrity management program and periodically inspected with PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 4 of 20 <<>> an in-line inspection technique. The special permit inspection area extends one-mile out from either side of the special permit segments long. This additional length was used since the Type B areas that are not being replaced are locations with 10 or fewer buildings intended for human occupancy in a “class location unit” and are outside the original “cluster area”. This special permit is contingent upon TGP’s incorporation of each of the special permit segments in its written integrity management program as a “covered segment” in a “high consequence area” (HCA) per 49 CFR 192.903. Criteria Matrix: The original and supplemental data submitted by TGP for the special permit segments have been compared to the class location change special permit criteria matrix. The special permit segments fall in the probable acceptance column of the criteria matrix for all criteria except for: • Possible acceptance – pipe manufacture and pipe material • Requires substantial justification – pipe coating, Stress Corrosion Cracking Direct Assessment (SCCDA), and several leaks within 20-miles of the special permit segment. The data findings below fall within the “probable acceptance” or the “requires substantial justification” columns of the criteria matrix: 1) Pipe design and construction, including pipe manufacture, material and design stress: • TGP pipeline special permit segments have: o Pipe manufactured with the following pipe seams: low-frequency electric resistance welded, flash welded, double submerged arc welded, seamless, and electric welded pipe seams. o Pipe coatings included: coal tar enamel, hot applied wax, fusion bonded epoxy, and tape. o Pipe design stress was 72% specified minimum yield strength or lower. 2) Pipe coating, SCCDA, and several leaks: TGP will be required to conduct a stress corrosion cracking assessment (SCCDA) of the special permit segments to evaluate where the risk of stress corrosion cracking (SCC) is present. TGP will be required to implement a plan to improve cathodic protection reliability and perform inspections for SCC during excavations. PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 5 of 20 <<>> • To further address pipe manufacturing, material, construction, pipe coating, SCCDA, and possible pipe leak issues, this special permit will include conditions requiring TGP to treat all special permit segments as “covered segments” in an HCA per 49 CFR 192.903. • TGP will also be required to perform ILI assessments, anomaly repairs, close interval surveys, identify any pipeline segment that may be susceptible to pipe seam issues because of the vintage of the pipe, the manufacturing process of the pipe, or other issues and stress corrosion cracking direct assessment (SCCDA) along the entire length of the special permit inspection areas and special permit segments according to the requirements of 49 CFR 192.929 after the grant of this special permit. • This special permit will include a condition that TGP must continue to operate each special permit segment at or below its existing MAOP. PHMSA has determined that imposing the special permit conditions will address these concerns and provide equivalent safety for these areas. Operational Integrity Compliance: To inform PHMSA’s decision about whether a special permit could provide a level of safety greater than or equal to a pipe replacement or pressure reduction and is consistent with pipeline safety, PHMSA reviewed this special permit request to understand the known type of integrity threats that are in the special permit segments and special permit inspection areas. This integrity information was used to consider special permit conditions to provide a systematic program to review and remediate the pipeline for safety concerns. Additional operational integrity review and remediation requirements are required by this special permit to ensure that the operator has an ongoing program to locate and remediate safety threats. These threats to integrity and safety include any issues with the pipe coating quality, cathodic protection effectiveness, operations damage prevention program, pipe depth of soil cover, weld seam and girth weld integrity, anomalies in the pipe steel and welds, and material and structures either along or near the pipeline that could cause the cathodic protection system to be ineffective. PHMSA has carefully designed a comprehensive set of conditions that TGP must implement to comply with this special permit.

PHMSA has designed the special permit conditions to effectively assess and remediate threats to the special permit segments and special permit inspection areas, including pressure testing, obtaining pipe material records, and conducting assessments to evaluate pipe girth welds that have not been non-destructively tested, any pipe with missing material records, and SCC. To ensure TGP properly implements the special permit conditions, TGP will be required to give PHMSA an annual review of their compliance with the special permit. PHMSA finds the issuance and full implementation of this special permit that waives the requirements of 49 CFR 192.611(a) and (d) and 192.619(a) for a class location change to a Class 3 location is not inconsistent with pipeline safety. This special permit requires TGP to implement the special permit conditions that include safety requirements on the operations, maintenance, and integrity management of the special permit segments and the special permit inspection areas. TGP will be required to implement the special permit conditions along the PHMSA-2016-0004 – Tennessee Pipeline Gas Company, LLC Special Permit Analysis and Findings Page 11 of 20 <<>> special permit segments and special permit inspection areas in pipeline segments that are not high consequence areas and would not normally be required by 49 CFR Part 192 to be assessed on a periodic interval for threats.
