The special\npermit segment does not apply to any aboveground piping or facilities or to any pipe made of\nmaterials other than Fiberspar LinePipe® fiberglass reinforced polyethylene plastic pipe or of\ndimensions not described herein.\nOn February 25, 2005, PHMSA granted the special permit based on the analysis set forth in the\n\"Special Permit Analysis and Findings\" document, which can be read in its entirety in Docket\nNo. PHMSA-RSPA-2004-18757, in the Federal Docket Management System (FDMS) located on\nthe Internet at www.regulations.gov. The special permit renewal is based on a review of\ndocuments provided by CGT in a renewal application letter dated November 10, 2016, tests and\ndocumentation required by the conditions within the original special permit, and PHMSA\ninspections conducted during the period in which the original special permit was in effect.\nConditions:\nThe renewal of this special permit is subject to CGT continuing to implement the following\nconditions on the special permit segment.\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal\nPage 3 of 14\n\n<<<PAGE 5>>>\n\n1) Maximum Allowable Operating Pressure: CGT must maintain a maximum allowable\noperating pressure (MAOP) of 825 pounds per square inch gauge (psig) for the special\npermit segment.\n2) Design Limitations: CGT must operate the 4-inch Fiberspar LinePipe® within the\nspecial permit segment and the special permit segment must not include Class 2, 3, and 4\nLocations (as defined in 49 CFR 192.5) or high consequence areas (as defined in 49 CFR\n192.903).\n3) Notifications to PHMSA and New York State, Department of Public Service: For\nany condition in this special permit renewal requiring CT to notify or send materials to\nPHMSA, CGT must additionally send notifications or copies to both the PHMSA\nDirector of State Programs and to the Supervisor of the New York State, Department of\nPublic Service, Office of Electricity, Gas & Water - Safety Section, which is the state\nauthority for the CGT pipeline through an interstate agent agreement with PHMSA.\n4) Procedures for Inspections, Remediation, and Tests: CT must continue to develop,\nimplement, and document procedures for the special permit segment as follows:\na.\nDevelop qualification procedures on joining methods through Fiberspar\ninstallation training courses and field training;\nb.\nInstallation qualification procedures and Fiberspar joining methods must be\navailable upon request to the Director, PHMSA Eastern Region;\nShould Fiberspar pipe remediation, replacement, repair, or new installations be\nrequired, CGT must have qualified Fiberspar personnel present and overseeing\nthe installation. Notice must be given to the Director, PHMSA Eastern Region, of\nthe date, time, and location of the remediation, replacement, repair, or new\ninstallation, and provide the Director an opportunity to witness the installation;\nSchedule five (5) inspections for 1, 2.5, 5, 7.5, and 10 years after installation;\nremove a minimum ten-foot pipe segment for inspection and perform both non-\ndestructive and destructive testing on the pipe material. Non-destructive testing\nshall focus on the composition and degradation of the fiberglass reinforced\npolyethylene plastic pipe material, and the destructive testing shall be a hydrotest\nto burst pressure. Upon request, the results of the inspections and tests must be\navailable to the Director, PHMSA Eastern Region;\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal\nPage 4 of 14\n\n<<<PAGE 6>>>\n\ne.\nSubmit Fiberspar fiberglass reinforced polyethylene plastic pipe to ASTM for\ntesting. If CT fails to submit this pipe material to ASTM for testing and have\nthis material listed as an acceptable material meeting ASTM requirement for new\nmaterials, and have a listing with the Plastics Pipe Institute (PPI) within five (5)\nyears of the pipe's original installation, CGT must discontinue use of this pipe\nmaterial at the end of the 5th year following initial installation, and comply with\nthe regulatory requirements of 49 CFR 192.53(c), 192.121, 192.123, and\n192.619(a). If it is determined that the commodity transported in this pipeline is\nnot compatible with, and proves detrimental to this pipe material, or if CGT does\nnot comply with any of these requirements, or the operational circumstances\nindicate that the special permit renewal compromises the safety of the pipeline,\npeople or property, PHMSA reserves the right to terminate this special permit\nrenewal.\n5) Inspections and Tests to Confirm MAOP for Future Operations:\na) CGT must schedule and perform inspections during which non-destructive and\ndestructive testing must be performed on the pipe material after installation.\nNondestructive testing shall focus on the composition and degradation of the pipe\nmaterial and destructive testing must include a hydrotest to burst pressure test.\nb) As required by the conditions in the original special permit, CGT has performed\ninspections and tests at approximately 1, 2.5, 5, 7.5, 10, and 12.5 years after\nconstruction.\nUnder renewal of the special permit, Condition 5 sets additional\nrequirements for inspections, testing, and related analyses. Condition 5 sets a\nnew schedule for inspections and tests going forward.\nc) Remove a minimum ten (10) foot pipe segment for inspection during each\ninspection.\nIn accordance with the requirements of this special permit renewal, CGT must\nperform removal, replacement, installation of pipe and fittings, and other actions\nrelated to the removal of test segments.\nAll inspections, testing, and related analyses required under Condition 5 after the\nspecial permit renewal must be performed every 24 months, not to exceed 30\nmonths, with the next to be performed prior to December 31, 2019.\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal\nPage 5 of 14\n\n<<<PAGE 7>>>\n\nf)\nPerform additional inspections, testing, and related analyses as follows:\n1. Short Term Hydrostatic Burst Pressure (STHB):\nCGT must modify the current STHB testing protocol to include a strain gage\nset up for the future test cycles. Bidirectional STHB pressure must be\ndetermined in duplicates with strain gages attached to the Fiberspar pipe in\naccordance with ASTM D1599-18, Standard Test Method for Resistance to\nShort-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings. In\naddition to the burst pressure, the focus of this test is on axial strain response\nunder bidirectional loading as a pressure vessel. Early deviation from linear\naxial strain response could indicate a poor (or deteriorated) fiber-to-resin\nbonding while increased axial strain responses at the same hoop stress level\ncould indicate a deteriorated resin matrix.\n2. Interlaminar Shear Strength (ILSS):\nCGT must determine ILSS in accordance with ASTM D2344 / D2344M-13,\n\"Standard Test Method for Short-Beam Strength of Polymer Matrix\nComposite Materials and Their Laminates\". The appropriate specimen\ngeometry must be used so the interlaminar shear will be the failure mode.\nLoss of ILSS could indicate a degraded fiber/resin bond and/or resin matrix.\n3. Dynamic Mechanic Analysis (DMA):\nOther than glass transition temperature determined in accordance with\nASTM D7028-07(2015), \"Standard Test Method for Glass Transition\nTemperature (DMA Tg) of Polymer Matrix Composites by Dynamic\nMechanical Analysis (DMA)\", storage modulus, loss modulus, and tan delta\nmust be calculated. Based on the information collected, CGT must evaluate\nthe resin and fiber/resin bond degradation of the Fiberspar pipe.\n4. Modulated Differential Scanning Calorimetry (DSC):\n• CGT must conduct Fiberspar pipe tests to determine the specific heat\ncapacity of the epoxy in the structural wall and High-Density Polyethylene\n(HDPE) liner in accordance with ASTM E2716-09(2014), \"Standard Test\nMethod for Determining Specific Heat Capacity by Sinusoidal Modulated\nTemperature Differential Scanning Calorimetry\". DSC is the standard test\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal Page 6 of 14\n\n<<<PAGE 8>>>\n\nmethod for determining specific heat capacity by Sinusoidal Modulated\nTemperature Differential Scanning Calorimetry. The primary goal of\nmodulated DSC is to determine the specific heat capacity of the resin\nmatrix. A higher specific heat capacity is typically associated with degraded\nresin matrix, although no obvious change in glass transition temperature is\nnoticeable.\n5. Monitoring and Reporting of Fiberspar Life Expectancy:\na. CGT must plot Fiberspar pipe burst pressures (current data and\nupdated with future test results when available) versus time in service.\nb. CGT must update and re-evaluate this Fiberspar pipe burst pressure\ngraph (see Figures 1 and 2 and Table 2 below, which were originally\nsubmitted by CGT) within 30 days of receipt of test results/report from\nthe laboratory for each required sample test and must utilize the\nadjusted graphs after each burst test to reevaluate the projected life\nexpectancy of the Fiberspar pipe.\nc. If the failure pressure ratio (FPR) (pipe burst pressure divided by\nMAOP) should meet or fall below 2.0, CGT must increase the\nCondition 5(e) test frequency to once per calendar year, but not to\nexceed 16 months, from the previous sample test date. As described in\nthe \"Proposed Sample Locations\", the order in which the pipe samples\nare harvested must not change.\nd. If the FPR should fall below 1.67, CGT must notify the Director,\nPHMSA Eastern Region as soon as practicable, but not to exceed 30\ndays, and the test plan and MAOP must be modified to ensure\noperational safety. The Director, PHMSA Eastern Region may\nconsider requiring changes to the special permit conditions, which may\ninclude, but are not limited to, sampling plan/timing, burst pressure\nlimits, adjustments to testing requirements, etc. CGT must calculate\nand report the estimated service life based on this data and the MAOP.\n6. The additional testing required by this Condition 5 must be conducted in\nconjunction with the continuation of CT's previous testing regimen (which\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal\nPage 7 of 14\n\n<<<PAGE 9>>>\n\nincluded Burst Pressure, Ultimate Axial Compression, Laminate Glass\nTransition Temperature, PE Linear Melting Point), per the original special\npermit and test samples extracted must be of adequate size to accommodate\nthis additional testing.\n7. All tests must be witnessed, analyzed, and test reports furnished by an\nindependent third-party expert. CGT must provide all test reports to the\nDirector, PHMSA Eastern Region, New York State Department of Public\nService, and Fiberspar. Note: Both Jana Laboratories Inc. (JANA), of\nAurora, Ontario, Canada and Woods Scientific have provided the third-party\nexpert inspection and inspection reports for the original special permit.\ng) CGT must monitor and report any other significant decreases or downward trends\nof other properties, including axial compression. CGT must notify the Director,\nPHMSA Eastern Region, as soon as practicable, but not to exceed 30 days, of any\npotential concerns with a decrease or downward trend and the test plan must be\nmodified to ensure operational safety. The Director, PHMSA Eastern Region\nmay consider requiring changes to the special permit conditions, which may\ninclude, but are not limited to, sampling plan/timing, burst pressure limits,\nadjustments to testing requirements, etc.\nh) CGT must report the results of the inspections and tests to the Director, PHMSA\nEastern Region within 60 days of completion of any testing required by the\nspecial permit renewal.\n6) Additional Conditions for the Special Permit Renewal:\na.\nCGT must monitor class locations and the development of any high consequence\narea in the special permit segment, and report any changes to PHMSA, within 30\ndays of any documented changes.\nb. CGT must conduct leakage detection surveys of the entire special permit segment\ntwo (2) times per calendar year at a minimum, not to exceed 7 ½ months between\nsurveys, utilizing industry standard leak detection equipment capable of parts per\nmillion detections of gas in air (flame ionization or similar). CGT must repair all\nleaks as they are found, and notify the Director, PHMSA Eastern Region of any\nleaks found as soon as it is safe to do so. Leak testing procedures, equipment, and\nPHMSA-RSPA-2004-18757: TransCanada, CGT - Special Permit Renewal\nPage 8 of 14\n\n<<<PAGE 10>>>\n\nscheduling must be documented within the CGT O&M Procedures. The first\nsurvey must be performed within 30 days of grant of this special permit renewal,\nor not more than 7 ½ months from the last leakage survey documented by CGT\nthat would have met the requirements of this Condition 6(b).\nc. If at any time, CGT becomes aware of a threat to the integrity of the special\npermit segment that poses a risk to the public or a failure risk, CGT shall notify\nthe Director, PHMSA Eastern Region immediately. Concurrent with such\nnotification, CGT must outline the potential mitigative and integrity measures that\nwill be used to address the threat or risk, including replacement with steel line\npipe per 49 CFR Part 192.\nd. CGT must notify the Director, PHMSA Eastern Region as soon as practicable, but\nnot to exceed 30 days, if:\n1. Repairs or modifications are required or made to the special permit segment\nFiberspar pipe, including fittings;\n2. The special permit segment is at any time damaged or hit; or\n3.
