This resulted in approximately 20 bbls of high Pressure propane migrating up the brine string. The facilities are designed to prevent any serious effects from resulting in such a case. A high Pressure alarm on the brine side of cavern E3 activated the high Pressure shut down to the ESDV's. The amount of propane that accessed the brine lines prior to closure of the ESDV was minor and was flared through the flare and burn pit, as per the System design. Amoco followed their emergency response procedures which included calling fire department officials who remained on Site until the controlled burn had been completed. The incident did not result in any damage to persons, wildlife, habitat, or the environment. All damage was restricted to the string within Amoco's underground salt caverns and there was no damage to any surface facilities. After the incident, Amoco de-pressurized the cavern by transferring the remaining propane to another cavern. Amoco has since determined that the brine string was sheared off at approximately 1388' below ground level and inside cavern E3. Damage was limited to the brine string in the cavern. Amoco suspects that the string failed due to shearing caused by a shale collapse. Amoco plans to replace the damaged brine string and tentatively scheduled to replace the brine string in May.

Upon closer examination, it was determined that the NPS Va Pressure relief valve on the power gas Pressure regulator for the 2:3 downstream tieover valve gas hydraulic operator was leaking. The regulator assembly was found to be frozen. The power gas supply was immediately shut off and the tieover valve was isolated as per TransCanada's Tag and Lockout Procedure. The regulator assembly was removed for further testing. A negligible amount of gas was released to the atmosphere. There were no injuries reported. On 23 February 2000, a nitrogen test was conducted on the regulator assembly in order to determine the cause of the incident. The test revealed that the Pressure relief valve was functioning properly and that the regulator froze as a result of a leak in the low- Pressure shutoff device (air relay valve) . Consequently, the air relay valve was replaced on 23 February 2000, at which time the power gas supply to the gas hydraulic operator was restored and the tieover valve was unlocked and readied for service. TransCanada analyzed the faulty air relay valve and discovered that the o-ring that seals the shaft of the device had migrated from its groove, and that the plastic bushing above this o-ring that allowed the shaft to move freely was loose and had shifted from its original position. TransCanada inspected 27 other air relay valves in Saskatchewan in conjunction with its annual valve Maintenance program, and discovered that five of the devices showed signs of similar problems with the o-ring, although none were leaking. Further investigation revealed that two designs are used for securing the o-ring in place: one design secures the o-ring through a tight fit between the stem and the spring retainer, while the other design secures the o- ring with a plastic bushing. It was determined that the plastic bushing type design was used in the device involved in this incident as well as the 5 devices identified by the inspections. TransCanada further noted that the o-ring used in all similar valves on its System are made of specifically developed compound for use on the TransCanada System (to resist deterioration due to operating conditions specific to TransCanada) .

Using a Lamb air mover, gas was successfully evacuated from the pipe between these valves and a hole was drilled near MLV 56-2 to facilitate gas testing. Tests using calibrated gas detection equipment confirmed that there was no gas present in the pipe at the test hole near MLV 56-2 or in the air being evacuated at the mover at MLV 56-2. When the welder lit his torch 21 metres away from the air mover in preparation for the cold cut near MLV 56- 2, there was an ignition at the air mover. The Lamb air mover was being powered by natural gas fed from a tap on the upstream side of MLV 56-2. This results in a flammable gas / air mixture which necessitates precautions be taken to ensure there is no source of ignition. One of the precautions is to ensure there is no residual gas in the pipe when the pipe is cut using a torch. This would result in ignition and a flame traveling through the pipe to the air mover. If and when this occurs, there is an audible bang along with a whooshing sound which indicates that an ignition has occurred in the pipe. In this case there was no noise indicating ignition. External ignition sources to be controlled are stray sparks, static electricity and metal to metal contact causing a spark. The welder was 21 metres from the air mover when he lit his torch and had not proceeded with the cut when ignition occurred. The likelihood that a stray spark from lighting a torch traveled 21 metres to the air mover is remote. The gasket between the flange of the air mover and the blow-off adaptor was present and in good condition preventing a spark from metal vibration. Air movers are electrically grounded preventing the build up of static electricity. As a result of the investigation, TransCanada has concluded that the only possible explanation for an ignition source is a spark generated by static electricity. A grounc] clamp is used to connect the flange on the air mover with the flange from the blow-off. One possible reason for the spark may have been improper grounding as both the flange on the air mover and blow-off adapter were painted. Thus, there may not have been good electrical contact via the ground clamp with either the air move and/or the blow-off to the grounding stake. The action of gas moving through an Expeller can result in a build up of static electricity if contaminated with solid or liquid particles (NFPA 77, 2-1. 2) . Also, on the day of the incident the weather was a bit unsettled which can result in an additional build up of ambient static electricity. During the investigation, TransCanada PipeLines contacted air mover manufacturers to inquire whether similar incidents had been reported when the movers were operated with natural gas. No incidents had been reported. At the time of the incident, TransCanada was in the process of preparing new Gas Handling Procedures. These procedures limit the use of gas for powering the air mover as follows: If the work Site is within two kilo Meter s of the Expeller location, Compressed Air must be used during welding procedures. Another point included in the same section of the procedures is To prevent a possible static discharge (spark) from occurring during the operation of the Expeller, ensure that the Expeller is properly grounded. This will prevent a possible ignition of the gas. Gas can be used to power the Expeller only by permission granted by the Regional Director and only where high humidity causes freezing off. The new procedures limiting the use of gas to power the Expellers should limit instances where an explosive gas to air mixture would occur in combination with ambient sparks. Grounding remains important as compressed air containing condensed water vapor often manifests strong electrification when escaping (NFPA 77, 6-| 2) . This is they only reported case the Board has on file where gas has ignited while exiting the Lamb air mover. If procedures are followed, the likelihood of recurrence is remote.

C. . The leak originated from the jacketing of a sulphur transfer line. The line requires heated jacketing in order to keep the sulphur in a molten state. The normal heating medium used is glycol. The section of jacketing was previously switched to steam service in order to melt a particularly stubborn, frozen section of sulphur. The steam traps had been installed as appurtenances to the glycol tracing System at that time and were located on the low points on the section of jacketing to provide for condensate drainage. At 4 p. m. on 10 May this section of jacketing was put back into glycol service. The steam supply was disconnected and the glycol supply and return were opened but the steam traps installed had been forgotten about as they should have been either removed or isolated. Thus, when the glycol was reintroduced to the System it began to escape onto the ground through the steam traps. A problem was first detected on 12th May when an operator conducting his daily control board rounds noticed the glycol level dropping. At this point, personnel began to investigate the low level. At 8 a. m. on the 15th May, a low glycol surge tank level alarm was received. Upon receipt of the alarm the search for the source of the leak was continuing. It took from the 12th May to the 16th of May to locate the source of the glycol leak. With respect to environmental impact of the incident, Westcoast stated in its Detailed Incident Report that there was no negative impact anticipated to the environment or off Site habitat. The area directly below leaking traps contained no freestanding glycol; this area is directly below several runs of piping. Surface water from spring runoff had collected in an area down gradient of the sulphur storage tanks (the spill Site) , which is a bermed containment area for the sulphur storage Site. This water was checked for evidence of gylcol migration, and was found to contain no glycol. There was no opportunity to collect free liquid from the spill Site. No further clean-up activity was undertaken, but monitoring is continuing. Any free liquid (surface water) from the bermed area, noted above, was pumped over to the sulphur runoff ponds for treatment as per Westcoast's Waste Management Act Permit PE-5615. As well Wesatcoast stated that down gradient Site observations on the day of the spill indicated that no free liquid migrated beyond the immediate spill Site.

This resulted in 133 x 103 m3 of throughput natural gas being vented to atmosphere for a duration of approximately 11 minutes at a discharge Pressure of 6890 kPa. Personnel manually isolated the valves and secured the unit. Investigation and temporary repairs were conducted the following day. Personnel discovered that a bared wire had shorted to ground causing the negative supply fuse to blow on the PLC Block No. 9. if the control block fails, the control logic will signal the unit valves to close and the unit vent valves to open in order to evacuate the unit piping. However, when the unit control logic was examined after this incident, it was found that the unit isolation failure logic had not included the unit vent valves. As a result of this incident, TransCanada modified the unit isolation failure logic for the A Plant s at Station s 25 and 68 with a final completion date of 7 December 2000. In the event the unit vent valve and one of the unit valves remain open for more than two minutes, the Station PLC will isolate the Plant . TransCanada currently has only two gas powered A Plant s in operation. The remainder have been retired or are powered via electricity.

WEI operations personnel manually shut-in the section of the 762 mm pipe surrounding the break. There was no ignition of the natural gas escaping from the pipeline. The occurrence Site was located approximately 46 kilo Meter s north of Hope, B. C. , and approximately 69 kilo Meter s south of Merritt, B. C. as measured along Highway No. 5 (Coquihalla Highway) . At this Site, the Coquihalla Highway is located about 100 metres west of the pipeline. The pipeline right of way runs parallel to and east of the Coquihalla Highway. The rupture occurred near the Zopkios rest area which is located to the west of the highway at Exit 217. At the time of the rupture there were several people sleeping in their vehicles across the highway at the Zopkios rest area. Some rock and soil debris from the rupture Site landed on the highway and in the rest area. Although some of the debris damaged nearby vehicles at the rest stop, there were no injuries. The Coquihalla highway was temporarily closed for approximately three and a half hours and reopened at 8:30 hours PDT on 7 August 2001. Board staff was dispatched to the rupture Site to conduct the incident investigation for the NEB. TSB investigators were also dispatched to the rupture Site. The length of ruptured pipe was approximately 26. 1 metres (85. 7 feet) ; a total of approximately 46. 3 metres of pipe (152 feet) was replaced. The rupture passed through two girth welds. The rupture traveled 18. 9 metres (62 feet) upstream and 7. 2 metres (23. 7 feet) downstream from the suspected point of initiation. Fracture initiation occurred in the pipe body at the 4 o'clock position. The fracture arrested in the pipe body both upstream and downstream from the fracture initiation point.

The on-call person met with the Area Manager, Support Services Manager, Support Services Pipeline Team Leader, Technical Services Pipeline Integrity Specialist and Reliability Engineer. A telephone conference was held with the System Integrity Team Leader located in Vancouver. Based on information received from the personnel at the Site, a decision was made to temporarily leave the Pipeline in service while arrangements were made to effect a permanent repair. That evening the Pipeline Integrity Specialist went to the Site to further assess the anomaly. Radiographic inspection, magnetic particle inspection and ultrasonic inspection, using both straight beam and angle beam probes, were used to determine the extent of a suspected crack responsible for the leak. This inspection confirmed that the leak was associated with a circumferential crack-like indication that was 3. 2 cm long on the outside dia Meter (ODinch) of the pipe. A similar but shorter linear indication was detected 3. 75 cm upstream of the leak. The shorter crack indication was also circumferential in orientation, and was approximately 2 cm in length. All exposed pipe was inspected for stress corrosion cracking. Only the two isolated circumferential crack-like indications were detected.

S. T. the M&NP System experienced a Pressure increase on the downstream side of the Saint John 16 inch lateral Pressure Reducing Station (PRS) which is located in a semi urban setting on the outskirts of Saint John New Brunswick. The Pressure increase resulted in a Pressure relief valve (approximately 2 inches in size) lifting open at the PRS and releasing natural gas to atmosphere. Natural gas was released to atmosphere for approximately one hour and thirty three minutes before it was eventually stopped via on Site intervention by M&NP personnel. The relief valve opened due to the failure of both the PRS's main and back-up Pressure Control Valves (PCVs) to continue to function. The PCV's are used to regulate the PRS's downstream Pressure . This failure of the PCV's ability to function was due to hydrates choking or freezing off the fuel gas supply to the Pressure regulators that in turn supply fuel/power gas to both PCV's.

Because the Station was drawing fuel from the Alternate Fuel Supply, the liquid slug ahead of the pipeline pig had an open path to flow past the Station into the 16-inch Nig Creek Pipeline and also to enter through the Station 's suction piping. Since compression was not operating, the liquid slug had an open path to flow to the Station discharge piping through the 4-inch check valve. The liquid slug was sufficiently large to be carried through the Alternate Fuel Supply past the #2 Station heating boiler's combustion chamber and collect in the debris tray beneath the combustion chamber. The volume of this tray determines a hydrocarbon condensate release volume of approximately 0. 025 m3.

C. there were a total of two releases of H2S into the atmosphere (one release on each of the two days) . The 28 April release occurred when a control instrument which monitors the level of water at the steam side of the # 1 sulphur condenser (B sulphur train) failed and mistakenly detected a low water level condition. The DCS based control System is configured to automatically initiate an emergency shut down (ESD) when a low water level is detected. The ESD caused the Reaction Furnace's Combustion Air Blower to shut down, the Acid Gas ESD Valve to begin to close and the air ESD valve to begin to close. As the Combustion Air Blower speed decreased the flow rate of air decreased until the blower and flow of air completely stopped thereby allowing a back- Pressure to flow up against a check valve which malfunctioned due to scoring on the shaft and bushings. The malfunctioning check valve allowed unburnt H2S laden acid gas to pass back through it and through a Surge Flow Control Valve to atmosphere outside of the A/B Utilities Building. Under normal operating conditions the combustion furnace or reaction furnace serves to combust some of the H2S laden Acid Gas to S02. The Reaction furnace was operating normally prior to the incident. However, early in the incident the combustion flame would have been extinguished and the combustion air depleted. With the flame extinguished, the H2S laden Acid Gas that was vented to atmosphere had not been burned off to convert it to S02. Following the 28 April incident, personnel repaired the failed low level transmitter. As well, they recognized that the check valve was in need of servicing. However, parts would have to be ordered which personnel did. They decided that with the having repaired the level transmitter the likely hood of the incident repeating itself before the check valve's ordered parts arrived would be highly unlikely.

At approximately 19:30 two other Operations and Maintenance employees were dispatched to the Laprise Station to confirm the safe condition of Unit #5 before another start attempt was made. When they arrived at the Station , they found the Kiene Indicator Valve open on the #11 power cylinder. They closed the valve and the unit was restarted. With the unit running, a more thorough check of the unit was made. This check revealed a fuel gas leak from a Dressier coupling on the fuel gas manifold near #11 power cylinder. The unit was again shut down and the leak was repaired. It was also noticed that the #10 power cylinder spark plug wire was disconnected from the spark plug. This may have caused an arc from the #10 power cylinder coil tower to the coil ground. This was repaired by attaching the spark plug lead to the spark plug.

Once the leak Site was identified, producer tie-in valves were immediately closed along the pipeline to isolate the pipeline from all gas sources. After the pipeline was isolated, the pipeline was depressurized by flaring the remaining gas. Depressurizing the pipeline enabled further inspection to occur. The leak occurred on line pipe approximately 0. 5 metres upstream of the tee and producer tie-in assembly. Since the producer tie-in is no longer active, Westcoast removed the affected piping plus the producer tie-in assembly and replaced it with approximately five metres of new pretested pipe.

He went outside and the noise of escaping gas was loud enough to lead him to believe that a small line had perhaps broken off near a relief valve. As he approached the area of the Station discharge piping for Compressor Unit No. 2, which is adjacent to relief valve PSV-0402 that is installed above a block valve, the gasket located in the flange above the block valve and below the relief valve blew out.

Enbridge has undertaken numerous corrective measures that should prevent a reoccurrence of a similar failure. Companies must ensure that they perform thorough condition monitoring and inspections when developing prioritization models. Board staff, are satisfied that Enbridge has identified the issue and has a plan in place to deal with any issues identified during the investigation. PII's willingness to examine the ultrasonic wall measurement data that it has gathered for echo loss and its program to better inform companies about the echo loss issue is a positive step in ensuring that failures due to echo loss are not repeated. Board staff are satisfied with PII's response to the issue There was no evidence to indicate that the PLC communications failure at Tonawanda contributed to the failure of Line 10. The PLC communications failure, however, did make it impossible for the CCO to access information from Tonawanda to assist in assessing the reason for the Pressure drop at MP 1896. Enbridge has implemented a plan to ensure that their SCADA and alarm System are functional.

While inspecting the 'A' Plant Auxiliary Wing, they discovered evidence that a small fire had occurred in the East exterior wall of the building, where the #1 auxiliary power unit (APU) exhaust piping exits through the building wall. In removing the interior metal cladding, personnel confirmed that some of the wooden framing material was burned. There had been no release of natural gas prior to or as a result of this incident. The incident did not pose a risk to the public or to the environment. The Auxiliary Wing is located immediately beside the 'A' Plant building and it houses three APU Units, Control Panels, starting air Compressor s, SCADA Terminal , firewater foam System and glycol/water filled cooling System for the 'A' Plant , and some miscellaneous electrical panels. The APU is designed to start automatically if power is disrupted for any reason. Records indicate the APU started automatically on two occasions this year, having run at least five hours each time. It is therefore suspected the fire took place sometime in the previous six weeks, and because it was limited to the interior of the wall, it was likely deprived of oxygen and self extinguished quickly. On April 5th, 2002, personnel conducted an on- Site investigation. During discussions with Site personal, it was discovered that modifications had been made to the exterior walls of the auxiliary wing in the mid. to late 1990s. Additional wooden framing was installed to support added insulation and new interior finishing panels were installed in the North, East and West walls. It was during these modifications that the contractor had apparently installed a sheet of 3/4 plywood close to the APU exhaust header. Personnel discovered a number of gaps between the exterior wall, where the header exits the building and the exhaust header insulation. The insulation did not cover the full length of the exhaust header to the exterior of the building. The insulation ended inside the wall creating another gap, which exposed the combustible materials to the radiant heat from the header. Further, the outer covering (tin) around the header had gaps, which allowed the heat to escape into the wall cavity. TransCanada has concluded that the radiant heat from the exhaust pipe had ignited the plywood and the fire was temporarily sustained by outside fresh air provided through the gap in the exterior wall. Personnel have inspected the other two APU units at Compressor Station 25 and found evidence of combustion around the exhaust exit points. All of the combustible materials around the exhausts have now been removed.",N/A,3/26/2002,N/A,N/A,0,0,0,02002-014,Other Event,4/3/2002,Westcoast Energy Inc.

The Taylor BC fire department blocked off the south end of the Alaska Highway and the RCMP blocked off the north end. The pipeline does have linebreak automatically controlled valves installed, however the Pressure did not drop low enough to initiate an automatic shutdown. According to the report provided by Duke Energy, a Duke employee was near the location of the rupture doing valve Maintenance when the rupture occurred. The employee was not injured (but was shook up pretty good!!) so contacted Gas Control to advise them of the problem and to shut down the line, before the Pressure dropped to a point to initiate automatic shutdown by linebreak valves. The location of the rupture was reported as approximately 3 miles from the upstream valve and 6. miles from the downstream valve. The gas was reported to have blown down within 20 minutes. The highway was allowed to open at approximately 17:07 MDT. There was no ignition of the gas release and hence . . . no fire. The gas was reported to have an H2S (sour gas) content of approximately 0. 41 percent. . . low. Houses and a trailer park located within 0. 5 km of the rupture Site were evacuated (not sure by who) . (Actually, it was the occupants of the houses and the trailer park that were evacuated.) When asked of the size of the crater, Duke Energy reported that the piping impacted by the rupture was largely above-ground piping near the pig launcher. FYI: In discussions with Duke Energy, it appears that there is a 26 inch dia Meter DC Trunk pipeline that runs parallel to this line and also along the Alaska Highway. This 26 inch line however, carries sour gas. Fortunately, this line did not appear to be impacted by the rupture of the adjacent line. There was no report of this line being shut down as a preventitive measure. Due to the closeness of the rupture to Fort St John, media attention is expected.

's Buick Creek Pipeline Booster Station Pigging Yard. The leak occurred as a result of an Operator closing an incorrect valve in the yard which resulted in line Pressure increasing to a level where the flange gasket began to leak. A producer (Samson Petroleum) that injects into Westcoast's Buick Creek gathering pipelines at the Pigging Yard had called Westcoast's Gas Control requesting to have its receipt point valve shut-in to allow Maintenance work to its System . Westcoast's Gas Control then dispatched an Operator to the Pigging Yard to close the Producers receipt point valve. However, due to a mislabeling of the valve (s) at the Site the Operator closed the main bypass valve for the Buick Creek line. The closed bypass valve went undetected for about 2 hours until Westcoast placed online its downstream Compressor Station # 1 and the McMahon Gas Plant which had both been down. Once both these facilities were operating for about 2 hours, Westcoast's Gas Control observed high Pressure s in the Buick Creek Pipeline. Gas Control then dispatched an Operator to the Pigging Yard. When the Operator arrived at the Site he observed a gas leak coming from underground. He re-examined the valving set up and recognized that the incorrect valve had been closed in error due to valve mislabeling. He then opened the bypass valve to allow the line Pressure to equalize between the 2 Buick Creek lines. When the Pressure equalized the leak emanating from the buried flange stopped. The bypass valve was then closed with all online Producers on the Buick Creek line having been asked to shut-in their facilities production to allow for repair of the flange leak. The 10 inch Buick Creek line and the Producers were out of operation from 8 October to 12 October 2002 while repairs were made.

Ontario border) . Product released was a low sulfur diesel and distillate. At the time of reporting, there was no idea of the volume of product released in the spill. Spill occurred in an agricultural field, which has drain tile throughout. TNPI indicated that some product entered a drainage ditch and that TNPI was in the process of using hay bales to filter and contain the spill and vacuum trucks to re-capture the product. Some product also entered a nearby stream as noted by a sheen on the surface of the water. TNPI is working to ensure all product is contained and kept away and out of all watercourses. TNPI indicated that a Pressure drop was noted by their Line Control leak warning System , at which time the TNPI Emergency Response team was dispatched. Nearest resident 0. 5 -1. 0 mi from leak Site. No evacuation was initiated. No fire. No injuries reported By the evening of Dec 7th, TNPI confirmed that the pipeline had indeed ruptured, as indicated by a Meter long rip in the pipe. Pipe had been daylighted (soil above pipe blew away) by the effect of the release. Pipeline was operating at 1200 psi prior to the rupture. TNPI was planning to work throughout the evening and to cutout an 8 Meter section and replace this section in the morning of Dec 8th and return the pipeline to operation later that day. The TSB was on Site during the excavation and cut out of the failed section. Preliminary analysis indicates that there may have been third party damage to the pipe, which could have lead to a fatigue-type failure. The TSB is sending the pipe to its lab where a full metallurgical examination will be done. At the time of reporting, the suspected cause was unconfirmed. TransNorthern has spoken to the nearby landowners and the other residents around the spill to let them know what was going on.

Terasen conducted a detailed investigation of the roof failure including: An independent failure analysis (by a tank engineering expert) Component examination and metallurgical assessment by an independent consulting firm, and Incident investigation by a multi-disciplined Terasen investigation team Terasen determined that the oil spill was caused by the structural failure of the floating roof. Degradation (corrosion) of key structural components (primarily the pontoon outer rim) in combination with the design of the roof and possibly the development of excessive rim loads or unbalanced loads (from the roof drain assembly) appear to have led to the development of a buckle through one pontoon. The buckle resulted in successive flooding of adjacent pontoons, allowing oil onto the roof deck and subsequently into the roof drain piping. From the roof drain piping oil was able to flow into the tank bay.

The 30x 600 Scrubber outlet flange gasket failed when the Pressure reached approximately 650 psig. The failure resulted in the release of approximately 44. 21 mscf of sweet natural gas. The operator immediately shut in the purge gas supply and depressurized the scrubber and all associated piping to allow Maintenance personnel to repair or replace the failed gasket. Maintenance personnel replaced the Durabia gasket with a Flex-o-talic gasket. Once the gasket was replaced, the Station was restored to service. Duke Energy advised Board staff that both gaskets (Durabia and Flex-o-talic) were ansi 600 # rated and both were deemed to be suitable for the application in which they were used. The gasket that failed was Durabia 600 #, and was/is not considered to be an incorrect gasket for this application. Further, Duke Energy advised Board staff that all work was completed by a qualified pipe fitter and helper and proper torque procedures were followed. Duke indicated that they had provided company operations the directive to ensure that proper torque procedures are to be followed when installing gaskets. Duke indicated that when flange gaskets are removed, they are always replaced with new gaskets. In this case, the Durabia gasket was replaced with a Flex-o-talic gasket. To prevent reoccurrence, it has been recommended by Duke to only use Flex-o-talic gaskets on high Pressure gas flanges in the future. Further, Duke indicated that there is a Duke directive to ensure that proper torque procedures are to be followed when installing gaskets.

At approximately 08:30 PST on 27 June, 2003 a group of DEGT employees commenced the blow down of a 19. 5 kilometre section of the 24-inch Sahtaneh Pipeline. De-pressuring of the pipeline was required in order to perform scheduled Maintenance on the pipeline during the Fort Nelson Gas Plant outage. In the planning stage for the Maintenance work and as a precautionary measure DEGT decided that during the gas flaring a crew would be placed on Site equipped with a 2-inch water pump, fire axes, shovels and backpack fire extinguishers. A helicopter equipped with a 150 gallon water bucket was also on Site to control any unintended ground fires. Two additional helicopters equipped with water buckets were also put on standby within 10 minutes travel time of the Site. The brush line is approximately 50 to 75 Meter s from the flare point and consists primarily of black spruce, muskeg and swamp. Note that this flare Site was blackened in January 2003. At approximately 16:30 PST, a strong gust of wind blew the flame from the flare towards the bush line and ignited some brush.

The area was isolated and the piping was allowed to bleed down. The crew attempted to tighten the flanges to get the gasket to seal, however, were unsuccessful!. A Flexitallic spiral-wound gasket was installed in place of the insulated gasket as a temporary measure to stop the leak. There were no injuries. Except for the release of sweet natural gas to the atmosphere, no environmental impacts were noted. Incident was reported to the NEB on July 09th by a Mr of Devon Canada. indicated that he contacted the NEB several times since June 26th in an attempt to report this incident, however, failed to get directed to personnel within the Operations Compliance team . On July 09th, was re-directed to Leo Jansen of the Operations Compliance Team. Leo took the information and advised of the One Window Incident Reporting approach throught the TSB and provided the TSB's reporting criteria and phone number. For this incident, the NEB will contact TSB to advise of the incident details etc. Of note is that the pipeline is owned by Alta Gas, however is operated by Devon Canada. An additional note to consider is that in July of 2001, an insulating gasket failure was the cause of a fire at the South Wapiti Gas Plant near Grande Prairie. According to Devon's incident report, the only thing that prevented this incident from becoming a repeat of the Wapiti fire, was the absence of an ignition source. Devon indicated that the helicopter used by the Meter proving crew to access the Site may have ignited the escaping gas, however the crew suspected problems in the area, so approached the Site from the upwind direction.

On Thursday 31 July 2003, company personnel began a pig sending and receiving operation. The pig receiving area was at a location referred to as Helmet Central. This is where the North Helmet 16 inch pipeline originates along with the 16 inch Peche Loop and a flare stack is located. As a result of the pigging operation, a massive hydrate and liquid slug built up in front of the pig. The hydraulics of the line being pigged were such that the gas flow behind the pig could not push the pig up several hills into the receiving barrel at Helmet Central, and the pig became stuck. Subsequently, the producers pipelines Pressure increased to the point of their shut down limits. This resulted in the producers facilities to shut down. The only method to get the pig into the receiving barrel was to flare off the gases and liquids via the flare stack at Helmet Central. This was done over a 4 day period from 31 July and 1, 2, and 3 of August. Flaring resulted in excess liquids and hydrates being pushed up the flare stack and spraying from the top of it. Ignited liquids landed on the ground resulting in small fires. This happened numerous times during the 4 days. Company practice requires a standby helicopter equipped with fire fighting equipment in the event that the flaring result in a fire. When the fires occurred, personnel would extinguish many fires by shoveling dirt onto them. The helicopter bucketed large amounts of water around the area to keep it wet and thus preventing the fires from spreading. The helicopter could make return water trips to the Site within one minute. The pig was finally received at the receiving barrel at approximately 1 p. m. local time on Sunday 3rd August 2003. It was later determined that the fires did migrate outside the boundaries of the flare Site at the receiving barrel. The Westcoast flare Site is 0. 836 hectares. It has been estimated that the total burn area was approximately 1 hectare in size. Virtually all of the area burned outside of the Westcoast flare Site (approximately 0. 164 ha) was composed of muskeg and weeds.",N/A,8/3/2003,N/A,N/A,0,0,0,02003-038,Release of Product,8/31/2003,Enbridge Pipelines Inc.,EPI - Line 1,Line 1,EPI - Glenboro Pump Station,Glenboro Pump Station,Natural Gas Liquids,High Vapour Pressure Product,0,,0,,0,0,Glenboro,Manitoba,,,"An alarm was noted by the Edmonton Control Center (ECC) at 10:47 MST on 31 Aug 2003, at the Glenboro Pump Station Line 1.

The gauger drained the varsol tank and removed the petcock to insert a hose to suck out any remaining liquid. As he attempted to insert the hose, a fire / flame shot out of the drain. The flame and varsol contacted the gauger's Nomex sleeve. The varsol carried to the sleeve with the flame and continued to burn on the gauger's Nomex sleeve. The gauger exited the lab and went to the snow covered ground and stopped, dropped and rolled, to extinguish the flame on his Nomex sleeve. He re-entered the lab and extinguished the remaining fire. The direct cause of the fire is that the heating element was not de-energized and when the fluid level dropped below the element it continued to heat until enough vapors were present to ignite. Damage included a burned plastic tray, a few papers / tickets and the lab counter top has a burn through the laminate as rags that were sitting on the counter, burned and smoldered while the gauger was extinguishing the flames on his Nomex sleeve.

The pipe was daylighted and found to be resting on bedrock. The crew was in the process or air lifting the pipe to examine the defect when the leak occurred. During the lift, LEL readings of 3. 6 % were detected and the crew immediately evacuated the trench. The operating Pressure was reduced to 2510 KPa (40% of MAOP) and the pipe was gently set back down in the trench. The leak was reduced to a minor gas trickle and remained stable.

TCPL is evaluating whether to blow down the line or to use a portable gas transfer Compressor to remove the gas from the line prior to repair. As the conditions at the Site are wet, it may be difficult to move in a portable Compressor , therefore TCPL expects this will be a blow down operation.
