Enbridge Kalamazoo cleanup now set at $1.157 billion and growing

The cost of Enbridge’s cleanup from the spill at Marshall, Michigan in 2010 is now $1.157 billion the company said Friday as it released its second quarter results. That is an increase of $35 million from the estimates Enbridge released at the end of 2013 and the first quarter of 2014.

As of June, 2014, Enbridge faces possibly $30 million in fines and penalties from the United States government.

In its quarterly report Enbridge said

EEP   [Embridge Energy Partners] continues to perform necessary remediation, restoration and monitoring of the areas affected by the Line 6B crude oil release. All the initiatives EEP is undertaking in the monitoring and restoration phase are intended to restore the crude oil release area to the satisfaction of the appropriate regulatory authorities.

On March 14, 2013, as previously reported, the United States Environmental Protection Agency ordered in Enbridge to undertake “additional containment and active recovery of submerged oil relating to the Line 6B crude oil release.”

new Enbridge logoEnbridge says it has “completed substantially all of the EPA order, “with the exception of required dredging in and around Morrow Lake and its delta.”

“Approximately $30 million of the increase in the total cost estimate during the three months ended June 30, 2014 is primarily related to the finalization of the MDEQ approved Schedule of Work and other costs related to the on-going river restoration activities near Ceresco,” Enbridge reported.

Enbridge also said it is working with the Michigan Department of Environmental Quality “to transition submerged oil reassessment, sheen management and sediment trap monitoring and maintenance activities from the EPA to the MDEQ, through a Kalamazoo River Residual Oil Monitoring and Maintenance Work Plan.”

Enbridge also said that costs may still go up, saying there continues to be the potential for “additional costs in connection with this crude oil release due to variations in any or all of the cost categories, including modified or revised requirements from regulatory agencies, in addition to fines and penalties and expenditures associated with litigation and settlement of claims.”

Enbridge said that “a majority of the costs incurred in connection with the crude oil release for Line 6B are covered by Enbridge’s comprehensive insurance policy…. which had an aggregate limit of  $650 million for pollution liability.” So far, Enbridge has recovered $547 million of the $650 million from its insurers. Enbridge is suing its insurers to recover the rest of the money.

That means that “Enbridge and its affiliates have exceeded the limits of their coverage under this insurance policy. Additionally, fines and penalties would not be covered under the existing insurance policy,” the company said.

Insurance renewed

Enbridge said it has “renewed its comprehensive property and liability insurance programs under which the Company is insured through April 30, 2015 with a liability aggregate limit of $700 million, including sudden and accidental pollution liability, with a deductible applicable to oil pollution events of $30 million per event, from the previous $10 million.”

It adds:

In the unlikely event multiple insurable incidents occur which exceed coverage limits within the same insurance period, the total insurance coverage will be allocated among Enbridge entities on an equitable basis based on an insurance allocation agreement among Enbridge and its subsidiaries.

All Enbridge figures are in US dollars

The Northern Gateway Joint Review Panel required Enbridge that “its Northern Gateway’s Financial Assurances Plan must provide a total coverage of $950 million for the costs of liabilities for, without limitation, cleanup, remediation, and other damages caused by the Project during the operations phase. The plan should include the following components and minimum coverage levels.” (That figure in Canadian dollars)

Enbridge’s Michigan cleanup costs now exceed JRP pipeline conditions for Gateway, SEC filing shows

The costs for Enbridge to clean up the 2010 Marshall, Michigan oil spill now far exceeds the maximum estimate that the Joint Review Panel gave for a major spill on the Northern Gateway Pipeline and also exceeds the amount of money the JRP ordered Enbridge to set aside to deal with a spill. Enbridge’s cleanup costs have also now edged past the higher liability amount requested by the Haisla Nation.

According to the US firm Enbridge Energy Partners’ filing with the United States Securities and Exchange Commission, as of September 30, 2013, the cost of cleanup was $1.035 billion US, not including possible additional fines and penalties that might be imposed by US authorities in the future.

In its decision, the Joint Review Panel estimated the cost a major oil spill from the Northern Gateway project would be about $693 million.  As part of the 209 conditions, the JRP ordered Enbridge to set aside “financial assurances” totaling $950 million.

Note all costs in this article are for a pipeline breach. The Joint Review Panel had different estimates for a tanker spill and the liability rules for marine traffic are different from pipelines.

In its filing for the third quarter of 2013, with the SEC, Enbridge Energy Partners say that the cost up until September 2013 had “exceed[ed] the limits of our insurance coverage.” The same filing says that Enbridge is in a legal dispute with one its insurers.

In its SEC filing, Enbridge says:

Lakehead Line 6B Crude Oil Release
We continue to perform necessary remediation, restoration and monitoring of the areas affected by the Line 6B crude oil release. All the initiatives we are undertaking in the monitoring and restoration phase are intended to restore the crude oil release area to the satisfaction of the appropriate regulatory authorities.
As of September 30, 2013, our total cost estimate for the Line 6B crude oil release is $1,035.0 million, which is an increase of $215.0 million as compared to December 31, 2012. This total estimate is before insurance recoveries and excluding additional fines and penalties which may be imposed by federal, state and local governmental agencies, other than the Pipeline and Hazardous Materials Safety Administration, or PHMSA, civil penalty of $3.7 million, we paid during the third quarter of 2012. On March 14, 2013, we received an order from the EPA, or the Environmental Protection Agency, which we refer to as the Order, that defined the scope which requires additional containment and active recovery of submerged oil relating to the Line 6B crude oil release. We submitted our initial proposed work plan required by the EPA on April 4, 2013, and we resubmitted the workplan on April 23, 2013. The EPA approved the Submerged Oil Recovery and Assessment workplan, or SORA, with modifications on May 8, 2013. We incorporated the modification and submitted an approved SORA on May 13, 2013. The Order states that the work must be completed by December 31, 2013.

The $175.0 million increase in the total cost estimate during the three month period ending March 31, 2013, was attributable to additional work required by the Order. The $40.0 million increase during the three month period ending June 30, 2013 was attributable to further refinement and definition of the additional dredging scope per the Order and associated environmental, permitting, waste removal and other related costs. The actual costs incurred may differ from the foregoing estimate as we complete the work plan with the EPA related to the Order and work with other regulatory agencies to assure that our work plan complies with their requirements. Any such incremental costs will not be recovered under our insurance policies as our costs for the incident at September 30, 2013 exceeded the limits of our insurance coverage.

According to the SEC filing, the breakdown of costs include $2.6 million paid to owners of homes adversely impacted by the spill.

Despite the efforts we have made to ensure the reasonableness of our estimates, changes to the recorded amounts associated with this release are possible as more reliable information becomes available. We continue to have the potential of incurring additional costs in connection with this crude oil release due to variations in any or all of the categories described above, including modified or revised requirements from regulatory agencies in addition to fines and penalties as well as expenditures associated with litigation and settlement of claims.
The material components underlying our total estimated loss for the cleanup, remediation and restoration associated with the Line 6B crude oil release include the following:
(in millions)

Response Personnel & Equipment  $454

Environmental Consultants  $193

Professional, regulatory and other $388

Total $ 1,035

For the nine month periods ended September 30, 2013 and 2012, we made payments of $62.3 million and $120.9 million, respectively, for costs associated with the Line 6B crude oil release. For the nine month period ended September 30, 2013, we recognized a $2.6 million impairment for homes purchased due to the Line 6B crude oil release which is included in the “Environmental costs, net of recoveries” on our consolidated statements of income. As of September 30, 2013 and December 31, 2012, we had a remaining estimated liability of $265.9 million and $115.8 million, respectively.

As for insurance, Enbridge Energy Partners say:

The claims for the crude oil release for Line 6B are covered by the insurance policy that expired on April 30, 2011, which had an aggregate limit of $650.0 million for pollution liability. Based on our remediation spending through September 30, 2013, we have exceeded the limits of coverage under this insurance policy. During the third quarter 2013, we received $42.0 million of insurance recoveries for a claim we filed in connection with the Line 6B crude oil release and recognized as a reduction to environmental cost in the second quarter of 2013. We recognized $170.0 million of insurance recoveries as reductions to “Environmental costs, net of recoveries” in our consolidated statements of income for the three and nine month periods ended September 30, 2012 for the Line 6B crude oil release. As of September 30, 2013, we have recorded total insurance recoveries of $547.0 million for the Line 6B crude oil release, out of the $650.0 million aggregate limit. We expect to record receivables for additional amounts we claim for recovery pursuant to our insurance policies during the period that we deem realization of the claim for recovery to be probable.

In March 2013, we and Enbridge filed a lawsuit against the insurers of our remaining $145.0 million coverage, as one particular insurer is disputing our recovery eligibility for costs related to our claim on the Line 6B crude oil release and the other remaining insurers assert that their payment is predicated on the outcome of our recovery with that insurer. We received a partial recovery payment of $42.0 million from the other remaining insurers and have since amended our lawsuit, such that it now includes only one insurer. While we believe that our claims for the remaining $103.0 million are covered under the policy, there can be no assurance that we will prevail in this lawsuit.

 

The Joint Review, Enbridge and Michigan

The Joint Review Panel based its finding on the Marshall, Michigan spill on the figure of $767 million from the summer of 2012 –again showing the limitations of the JRP’s evidentiary deadlines since the costs are now much higher.

The JRP quoted Enbridge as saying:

Northern Gateway considered the high costs of the Marshall, Michigan spill, which were at least $252,000 per cubic metre ($40,000 per barrel), to be an outlier or a rare event because the spill occurred in a densely populated area, because the pipeline’s response time was abnormally long, and because there was the prospect of potentially lengthy legal proceedings.

Enbridge assured the JRP that the corporate culture and management changes and equipment upgrades since the Marshall, Michigan spill lowered that chances of a similar event.

The company based its models for the JRP on much smaller spills, including one spill at Lake Wabamun, Alberta from a train not a pipeline (Vol. 2 p 357)

Enbridge’s risk assessment did not “generate an estimate of economic losses caused
by a spill.”

The JRP says Northern Gateway relied on its analysis of literature, and spill events experienced by Enbridge and other liquid hydrocarbon carriers in Alberta and British Columbia. After assessing all of this information, Northern Gateway regarded the high costs of a cleanup as “conservative”–meaning the company expects costs to be lower than its estimates in evidence before the JRP.

In Northern Gateway’s view the most costly pipeline spill incident would be a full-bore oil pipeline rupture, with an estimated cost of $200 million, and an extremely low probability of occurrence.

Haisla evidence

In their evidence, the Haisla (and other First Nations and intervenors) were doubtful about Northern Gateway’s assurances. The Haisla asked that Enbridge have a minimum of $1 billion in liability, an amount Enbridge has now exceeded in Michigan.

Haisla Nation estimated the cost of damage to ecosystem services because of a terrestrial oil spill from Northern Gateway’s pipeline would be in the range of $12,000 to $610 million for a 30-year period.

The Haisla’s cost estimates were based on values for environmental goods and services and probabilities of spills that were independent of Northern Gateway’s parameters for estimating oil spill costs. In contrast to Northern Gateway’s estimated spill frequency and costs, the Haisla predicted that spills would occur more often and placed a higher value on damages to environmental goods and services.

Haisla Nation argued that Northern Gateway overestimated its ability to detect and respond to a spill. In the Haisla’s view this resulted in the cost of a spill and the requisite financial assurances being understated. Haisla cited several factors, including: remote location, limited access, challenging terrain, seasonal conditions, and river flow conditions that would cause the cost of cleaning up a spill in the Kitimat River valley to be significantly greater than the costs associated with Enbridge’s Marshall, Michigan spill.

For these reasons, Haisla proposed that Northern Gateway should be required to obtain a minimum of $1 billion of liability coverage through insurance and financial assurances. Haisla said that Northern Gateway should file annually the report from an independent third party assessing the financial assurances plan. (Vol 2 p359)

In response Northern Gateway said:

Northern Gateway said that Haisla’s findings were based on a number of fundamental methodological flaws and a lack of probability analysis to support the high frequency of occurrence of oil spill events. Northern Gateway argued that Haisla’s estimates of ecosystem service values were inflated because they were based on values from unrelated studies. In Northern Gateway’s view, Haisla relied on high passive use values that were not justified.

JRP ruling

As it has in most of its decision, the JRP accepted Northern Gateway’s evidence, including its explanation of the Marshall, Michigan spill and then went on to base its spill cost estimates not on a pipeline breach but on the 2005 railway spill at Lake Wabumum, near White Sands, Alberta.

The Panel accepts that the cleanup costs for the Marshall, Michigan spill were orders of magnitude higher because of the extended response time. In this application, the Panel accepts Northern Gateway’s commitment to complete the shutdown in no more than 13 minutes after detection. For this reason the Panel did not use the Marshall spill costs in its calculations. The spill volume and the resulting costs are directly dependent on the Northern Gateway’s control room staff and the pipeline control system fully closing the adjacent block valves no longer than 13 minutes from the detection of an alarm event, as well as the amount of oil which would drain out of the pipeline after valve closure due to elevation differences.

The Panel decided on a total unit cost of $138,376 per cubic metre ($22,000 per barrel). This is midway between the unit cost of $88,058 per cubic metre ($14,000) per barrel proposed by Northern Gateway and the unit cost of $188,694 per cubic metre ($30,000 per barrel) for the Lake Wabamun spill. It is about one-half of the Marshall spill’s unit cost. Giving weight to the Lake Wabamun costs recognizes actual costs experienced in a Canadian spill and the greater costs of spills in high consequence areas. In these areas, individuals, populations, property, and the environment would have a high sensitivity to hydrocarbon spills. The deleterious effects of the spill would increase with the spill volume, the extent of the spill, and the difficulty in accessing the spill area for cleanup and remediation.

Using these spill volume and unit cost values in the calculation below, the Panel estimated the total cost of a large spill could be $700 million. Total cost of a spill = 31,500 barrels x $22,000 per barrel = $693 million, or $700 million when rounded up.

(p362)

The Panel based the financial assurances requirements for Northern Gateway on a spill with a total estimated cost of $700 million and directs Northern Gateway to develop a financial assurances plan with a total coverage of $950 million that would include the following components:
i. Ready cash of $100 million to cover the initial costs of a spill;
ii. Core coverage of $600 million that is made up of stand-alone, third party liability insurance and other appropriate financial assurance instruments, and
iii. Financial backstopping via parental, other third party guarantees, or no fault insurance of at least $250 million to cover costs that exceed the payout of components i. and ii.
The financial backstopping would be available to fill the gap if the spill volumes or unit costs were under-estimated or if the payout from the core coverage would be less than 100 per cent.

The Panel noted that:

The evidence indicates that there is some probability that a large oil spill may occur at some time over the life of the project. In these circumstances the Panel must take a careful and precautionary approach because of the high consequences of a large spill. The Panel has decided that Northern Gateway must arrange and maintain sufficient financial assurances to cover potential risks and liabilities related to large oil spills during the operating life of the project.

Northern Gateway committed to investing $500 million in additional facilities and mitigation measures such as thicker wall pipe, more block valves, more in-line inspections, and complementary leak detection systems. This initiative should enhance the safety and reliability of the system and help reduce and mitigate the effects of a spill, but it would not eliminate the risk or costs of spills. This initiative is not a direct substitute for third party liability insurance and does not eliminate the need for liability insurance or any other form of financial assurance to cover the cost of a spill. (p 361)

So the JRP decision comes down to this, if you accept Northern Gateway’s position that pipeline spills are rare and mostly small, then the company has the financial resources to cover the damage. If, however, Northern Gateway is wrong and the costs of a pipeline cleanup exceed the $950 million required by the Joint Review Panel, as has happened in Michigan, then those JRP conditions are already obsolete.

Enbridge misses deadline to clean up Michigan’s Morrow Lake; EPA cites reluctance to do winter cleanup

EPA map of Kalamazoo River
EPA map of river closures and dredging operations on the Kalamazoo River during 2013. (EPA)

Enbridge has missed the US Environmental Protection Agency’s deadline to clean up parts of the Marshall, Michigan bitumen spill by December 31, 2013.

Local television news, WOOD-TV says the EPA is now considering “enforcement options.”
The EPA had already granted Enbridge a 10 month extension that the company requested in March, 2013, setting the new December deadline.

In November, Enbridge requested a second extension. The EPA denied that request.

From the EPA letter it appears that, as in previous years, Enbridge is trying to avoid continuing clean up work into the winter. The EPA rejects that position, telling Enbridge it shouldn’t wait until the spring run off could spread the sunken bitumen.

The EPA says that beginning in March, 2013, “Enbridge has successfully removed oil and sediment from two of the three major impoundment areas identified in the order and from several smaller sediment trap locations.”

The area that Enbridge failed to clean up is known as the Morrow Lake and Morrow Lake Delta. The cleanup in that area was delayed when the Comstock Township planning commission unanimously  denied Enbridge a permit for “dredge pad” after fierce public opposition

The letter to Enbridge, from Jeffrey Kimble, Federal On-Scene Coordinator denying the extension is another scathing indictment of Enbridge’s attitude toward the public and the cleanup, citing Enbridge failing to prepare “adequate contingency plans,” by failing to recognize the “serious opposition” the dredging plans.

Although the EPA had told Enbridge to consider alternative plans—and Enbridge claimed it did that—the EPA found the Enbridge’s own logs showed the company didn’t start considering alternatives until it was obvious that Comstock Township would reject their dredging plans.

The EPA letter also reveals that once again Enbridge is reluctant to do further cleanup work during the Michigan winter. The EPA rejects that stance, saying that “Removal of oiled sediments prior to the spring thaw will lessen the potential oiled sediment transport in the spring to Morrow Lake via increased river velocities from rain and ice melt.”

Although we recognize that the work required by the Order is unlikely to be completed by December 31, 2013, U.S. EPA believes that had Enbridge taken appropriate steps earlier as requested, it would not require an extension now. In particular, U.S. EPA believes that Enbridge has continuously failed to prepare adequate contingency plans for a project of this nature. For example, U.S. EPA acknowledges that failure to obtain a site plan approval for use of the CCP property for a dredge pad was a setback in the timely completion of the work in the Delta.

However, Enbridge failed to prepare any contingency plans recognizing the possibility of such an occurrence. Enbridge has known since at least the middle of July 2013 that there was serious opposition to its proposed use of the CCP property. When it became clear in August 2013 that opposition to the site use might delay the project, U.S. EPA directed Enbridge to “conduct a more detailed review of your options in short order.”

Although your letter claims that Enbridge “has considered such alternatives,” your logs indicate that Enbridge did not hold initial discussions with the majority of these property owners until long after the final decision to abandon plans for use of the CCP property. These contact logs do not demonstrate that Enbridge fully explored and reviewed alternative options in a timely manner so as to avoid delay in completion of the work. Although Enbridge claims that use of identified alternative properties would be denied by Comstock Township, Enbridge did not present any site plans to the Township for approval (other than use of the county park for staging of frac tanks). To the extent that any of Enbridge’s contingency plans include the use of land for dredge pads, U.S. EPA believes that Enbridge should begin multiple submissions for property use until one is accepted….

Enbridge claims that it cannot install winter containment in the Delta to prevent the potential migration of sediments to the lake. To support that claim, Enbridge has attached a letter from STS directing Enbridge to remove anchors and associated soft containment during winter monthsas these structures could damage STS’s turbines. However, none of the correspondence provided by Enbridge discusses the use of more secure containment methods, such as metal sheet piling, which may not pose the same risks as soft containment structures. Enbridge should consider using sheet piling to construct cells which would both allow winter work and contain the sediment during that work. Enbridge should therefore try to obtain access from STS for this specific work, and for other appropriate work, for the winter timeframe. Use of sheet pile cells would allow continued operations during the winter, especially in the southern zone of the Delta outside of the main river channel. Removal of oiled sediments prior to the spring thaw will lessen the potential oiled sediment transport in the spring to Morrow Lake via increased river
velocities from rain and ice melt.

Finally, U.S. EPA is unwilling to allow Enbridge to wait until after the likely spring high
velocity river flush to reinstall the E-4 containment structures. U.S. EPA has reviewed Enbridge’s modeling, which Enbridge claims supports its requested timeline, and has found it incomplete. The model has not incorporated, and does not match, field observation of flow velocities and water levels and their potential to impact upstream critical structures if containment is in place. Moreover, U.S. EPA completely disagrees with Enbridge’s assertion that there is no evidence of migration of submerged oil during high flow events. The results of three years of poling and sheen tracking demonstrate that Line 6B oil is mobile during periods of
high flow. Now that Enbridge has a five year permit from MDEQ for the E-4 containment system, U.S. EPA reiterates that this containment must be in place immediately upon thawconditions in the spring….

Although Enbridge’s proposed two phase approach may have components that can be incorporated into a final plan, it should not be considered the approved way forward. U.S. EPA believes that pausing the work cycle until new poling can be done in June or July of 2014 could again result in a wasted construction season in the Delta. Enbridge should consider and utilize a combination of techniques in the plan. For example, several dredge pad sites have been identified by Enbridge. Enbridge should obtain approval for one of these sites, or a combination of smaller sites, so as to support hydraulic dredging in conjunction with the current approved
approach and any potential dry excavation techniques. Enbridge should also consider other winter work techniques, such as cell build out and dewatering in the Delta via sheet piling.

As always, U.S. EPA will continue to work with Enbridge to develop adequate plans and complete the work required by the Order. However, nothing in this letter excuses any noncompliance with the Order nor does it serve as the granting of any extension to any deadline in the Order. U.S. EPA reserves all its rights to pursue an enforcement action for any noncompliance with the Order.

The EPA letter also calls into question the ruling of the Joint Review Panel on the Enbridge Northern Gateway. The JRP accepts, without question, Enbridge’s assurances that the company has changed its attitude and policies since the long delay in 2010 in detecting the pipeline rupture in Marshall, Michigan.

The JRP, on the other hand, accepts, without question, Enbridge’s assurances that it has expertise in winter oil recovery from a pipeline spill.

Parties questioned Northern Gateway about locating and recovering oil under ice. Northern Gateway said that Enbridge conducts emergency exercises in winter and that Northern Gateway would learn from those experiences.
Northern Gateway outlined a number of oil detection techniques including visual assessment (at ice cracks and along the banks), drills, probes, aircraft, sniffer dogs, and trajectory modelling. It said that, once located, oil would be recovered by cutting slots into the ice and using booms, skimmers, and pump systems to capture oil travelling under the ice surface.

The company said that oil stranded under ice or along banks would be recovered as the ice started to melt and break up. It discussed examples of winter oil recovery operations during Enbridge’s Marshall, Michigan incident, and said that operational recovery decisions would be made by the Unified Command according to the circumstances.

Northern Gateway said that equipment caches would be pre-positioned at strategic locations, such as the west portal of the Hoult tunnel. It said that decisions regarding the location or use of pre-positioned equipment caches would be made during detailed design and planning, based on a number of considerations including, but not limited to, probability of a spill, access, site security,
environmental sensitivities, and potential for oil recovery at the response site.

(vol 2 page 153)

In its ruling, the Joint Review Panel said

The Panel finds that Northern Gateway’s extensive evidence regarding oil spill modelling, prevention, planning, and response was adequately tested during the proceeding, and was credible and sufficient for this stage in the regulatory process.
Parties such as the Province of British Columbia, Gitxaala Nation, Haisla Nation, and Coalition argued that Northern Gateway had not provided enough information to inform the Panel about proposed emergency preparedness and response planning. The Panel does not share this view.

Northern Gateway and other parties have provided sufficient information to inform the Panel’s views and requirements regarding malfunctions, accidents, and emergency preparedness and response planning at this stage of the regulatory process.

Many parties said that Northern Gateway had not demonstrated that its spill response would be “effective.” Various parties had differing views as to what an effective spill response would entail.

The Panel is of the view that an effective response would include stopping or containing the source of the spill, reducing harm to the natural and socio-economic environment to the greatest extent possible through timely response actions, and appropriate follow-up and monitoring and long-term cleanup. Based on the evidence, in the Panel’s view, adequate preparation and planning can lead to an effective response, but the ultimate success of the response would not be fully known
until the time of the spill event due to the many factors which could inhibit the effectiveness of the response. The Panel finds that Northern Gateway is being proactive in its planning and preparation for effective spill response….

The Panel is of the view that an effective response does not guarantee recovery of all spilled oil, and that that no such guarantee could be provided, particularly in the event of a large terrestrial, freshwater, or marine spill.

The oil spill preparedness and response commitments made by Northern Gateway cannot ensure recovery of the majority of oil from a large spill. Recovery of the majority of spilled oil may be possible under some conditions, but experience indicates that oil recovery may be very low due to factors such as weather conditions, difficult access, and sub-optimal response time, particularly for large marine spills. …

To verify compliance with Northern Gateway’s commitments regarding emergency preparedness and response, and to demonstrate that Northern Gateway has developed appropriate site-specific emergency preparedness and response measures, the Panel requires Northern Gateway to demonstrate
that it is able to appropriately respond to an emergency for each 10-kilometre-long segment of the pipeline.

The Panel notes the concerns of intervenors regarding Northern Gateway’s ability to respond efficiently and effectively to incidents in remote areas, and its plan to consider this during detailed design and planning. The Panel finds that Northern Gateway’s commitment to respond immediately to all spills and to incorporate response time targets within its spill response planning is sufficient to
address these concerns. Northern Gateway said that its emergency response plans would incorporate a target of 6 to 12 hours for internal resources to arrive at the site of a spill. It also said that it would target a response time of 2 to 4 hours at certain river control points.

The Panel agrees with Northern Gateway and several intervenors that access to remote areas for emergency response and severe environmental conditions pose substantial challenges. The Panel notes that the company has committed to develop detailed access management plans and to evaluate contingencies where timely ground or air access is not available due to weather, snow, or other logistic
or safety issues.

Despite the EPA letter (which admittedly was released long after the JRP evidentiary deadline) that shows that Enbridge did not consult the people of Comstock Township, Michigan, the JRP says

The Panel accepts Northern Gateway’s commitment to consult with communities, Aboriginal groups, and regulatory authorities. The objective of this consultation is to refine its emergency preparedness and response procedures by gaining local knowledge of the challenges that would be present in different locations at different times of the year

EPA Orders Enbridge to Perform Additional Dredging to Remove Oil from Kalamazoo River

The United States Environmental Protection Agency has ordered Enbridge to dredge the Kalamazoo River to remove addition bitumen.

The EPA issued this news release

CHICAGO (March 14, 2013) – The U.S. Environmental Protection Agency today issued an administrative order that requires Enbridge to do additional dredging in Michigan’s Kalamazoo River to clean up oil from the company’s July 2010 pipeline spill. EPA’s order requires dredging in sections of the river above Ceresco Dam, upstream of Battle Creek, and in the Morrow Lake Delta.

EPA has repeatedly documented the presence of recoverable submerged oil in the sections of the river identified in the order and has determined that submerged oil in these areas can be recovered by dredging. The dredging activity required by EPA’s order will prevent submerged oil from migrating to downstream areas where it will be more difficult or impossible to recover.

Enbridge has five days to respond to the order and 15 days to provide EPA with a work plan. Dredging is anticipated to begin this spring and is not expected to result in closures of the river. EPA’s order also requires Enbridge to maintain sediment traps throughout the river to capture oil outside the dredge areas.

On July 26, 2010, Enbridge reported that a 30-inch oil pipeline ruptured near Marshall, Michigan. Heavy rains caused the spilled oil to travel 35 miles downstream before it was contained.

 

Enbridge faces $68,000 fine for not inspecting pipeline branch in Ohio

Enbridge is facing a new penalty from the US Pipeline and Hazardous Materials Administration for not inspecting a pipeline branch in Ohio and Michigan. The decision by the PHMSA comes just after a couple of days after the agency acknowledged that Enbridge had paid the civil penalty for the Marshall, Michigan oil spill with a wire transfer to the US Treasury of $3,699,200 on August 12. It was the Marshall pipeline breach and spill that led to bitumen entering the Kalamazoo River.

The new proposed penalty is much lower, just $68,000. It relates to the PHMSA inspection of Enbridge’s Toledo pipeline between July 12 and July 15, 2010.

The PHMSA says it found three alleged violations of federal pipeline safety regulations.

As well as the proposed civil penalty of $68,000, Enbridge Toledo is required to submit past records for inspections of subsequent overpressure safety devices and out-of-service tanks
The agency lists the violations as:

1. Failure to adequately inspect the right-of-way at a mainline valve location in Toledo as required by 49 CFR §195.412.
No proposed penalty — Warning Item.
1. Exceeding the maximum interval for inspection of 12 overpressure safety devices as required by 49 CFR §195.428.
Proposed penalty is $39,000 + PCO.
1. Exceeding the maximum interval for API 653 internal inspections of two breakout tanks located at Stockbridge, MI as required by 49 CFR §195.432.
Proposed penalty is $29,600 + PCO.

Enbridge can, if it wishes, challenge the NOPV (Notice of Possible Violation) in court.  In the case of the original Marshall, Michigan, spill NOPV, Enbridge did not challenge the findings of the PHMSA and paid the penalty.

The new document sent to Enbridge by David Barrett, PHMSA Director, Central Region says that the company failed to perform internal inspections or establish a corrosion rate for the bottom plates of its tanks within the 10 year period as required by US regulations. It also says Enbridge failed to demonstrate that they had established a basis for the corrosion rate for the tank bottoms and exceeded the 10 year maximum internal inspection interval for unknown corrosion rates.

Additionally, Enbridge did not have similar service experience, or procedures to apply similar service experience available to make this inspection interval determination.

The PHMSA also says that Enbridge Enbridge failed to inspect its overpressure safety devices at intervals not exceeding 15 months, but at least once each calendar year. The inspection intervals exceeded the maximum 15 month interval by 14-24 days for the overpressure safety devices listed int the order.

The compliance order calls for Enbridge to submit documentation of all inspections performed on
each of the tanks and overpressure devices listed in the PHMSA order from 2010 to present. Enbridge has to internally inspect each of the tanks and to submit to the PHMSA documentation on the “safety improvement costs” needed to comply with the order.

As for the Marshall, Michigan spill, while Enbridge promptly paid the civil penalty, the PHMSA order notes

This Order does not resolve any existing or potential civil or criminal liability that Enbridge may have for any other violations of the federal Pipeline Safety Laws, or any regulations or orders issued thereunder, not specifically enumerated herein. Further, this Order does not resolve any existing or potential civil or criminal liability that Enbridge may have for violations ofany other federal laws arising from or otherwise related to the events or conduct giving rise to this Order or
to the consequences or damages resulting from the Failure.

NEB conducting safety audit of Enbridge

The National Energy Board is following up a highly critical report by the US National Transportation Safety Board on the Marshall, Michigan spill by conducting an overall safety audit of Enbridge pipeline management and practices.  The NEB says the review began even before the NTSB report was released:

even prior to the release of the final report, we have been reviewing Enbridge’s management practices. In the next weeks and months, we will be conducting safety audits to review and confirm that improvements, particularly to their control room practices in Edmonton, are satisfactory.

In a letter to the public from NEB chair, Gaétan Caron, posted on the NEB website, the agency says: “Pipeline safety is and always has been of paramount concern to the National Energy Board and we recognize it is of growing concern to Canadians.”

The letter goes on to say:

Given recent events, it is important that Canadians understand how we hold companies accountable for public safety and protection of the environment and take swift and appropriate action when they do not.

The Board takes a proactive approach to preventing spills and releases, with the ultimate goal of seeing none at all. We require pipeline companies to anticipate, prevent, manage and mitigate potentially dangerous conditions associated with their pipelines.

To do this, we conduct compliance verification activities which include things such as inspections, compliance meetings, emergency exercises, audits and investigations on a regular basis with all companies we regulate. In the specific case of Enbridge, in recent years the NEB has conducted approximately 25 compliance verification activities per year, focusing on every aspect of their management system. In addition, the NEB imposed two precautionary pressure restrictions on Enbridge pipelines, one in 2010 and another in 2011, which remain in effect.

When the NEB identifies deficiencies in a company’s systems, projects or programs, we require the company to immediately implement changes to correct those deficiencies or to develop a corrective action plan for NEB approval. It is important to note that we aim to prevent incidents from occurring in the first place and we will take all available actions at our disposal to protect the environment and the public. The NEB may revoke authorizations, impose safety orders that restrict operations, issue stop-work orders and monetary penalties as well as pursue criminal prosecution.

The NEB has also reviewed the synopsis of the National Transportation Safety Board’s report on Enbridge’s Line 6B rupture in Michigan in 2010 to see what we can learn in the interests of public safety and environmental protection. A thorough review of the final report will be conducted in order to identify all lessons that may be applied to pipelines and companies under the Board’s jurisdiction, however even prior to the release of the final report, we have been reviewing Enbridge’s management practices. In the next weeks and months, we will be conducting safety audits to review and confirm that improvements, particularly to their control room practices in Edmonton, are satisfactory.

The NEB goes on to stay that Jobs, Growth and Long-term Prosperity Act (formerly Bill C-38) is giving the agency more bight:

 the Government of Canada will be adding another tool to our compliance and enforcement toolkit: administrative monetary penalties (AMPs). The new AMP sections in the NEB Act set out the maximum daily penalties for both individuals and companies. For individuals the maximum daily penalty is $25,000 for each violation and for companies the maximum daily penalty is $100,000 per violation.

The Act stipulates that each day a violation continues is considered to be a separate violation. This means that separate penalties could be issued per infraction, per day with no maximum total financial penalty.

Some of the details of the AMPs design are described in the government amendments to the NEB Act, but other details, such as what activities will be considered violations, will be written in a new regulation. We have committed to have these new regulations ready to use by July 6, 2013.

The NEB says it will continue to make public any enforcement measures it takes.

As a part of our Action Plan on Safety and Environmental Protection, we began posting all documents related to Board-initiated safety and environmental compliance actions to our website in fall of 2011.

The Board is committed to continually improving the way we do business and we welcome any opportunity that allows us to do so in the interests of pipeline safety and environmental protection.

Enbridge has not yet responded to the NEB release.

Haisla ask Gateway JRP to force Enbridge to release more Kalamazoo spill information

The Haisla Nation have asked the Northern Gateway Joint Review panel to force Enbridge to reveal more information about the pipeline rupture and oil spill near Kalamazoo, Michigan, in July 2010. The Haisla are also asking for more and better information about the $500 million project upgrades that Enbridge announced last month.

In a notice of motion filed July 30, with the JRP, lawyers representing the Haisla Nation note that they had previously asked Enbridge “a number of questions relating to Enbridge’s spill of 3,785,000 litres of diluted bitumen into the Kalamazoo River at Marshall, Michigan (the ‘Kalamazoo Spill’).”

The notice then notes that “Northern Gateway refused to reply as the matter was under investigation by the United States National Transportation Safety Board… The NTSB’s Accident Report was adopted on July 10, 2012 and has now been released to the public. The basis for Northern Gateway’s refusal to answer the Haisla Nation’s information requests is, therefore, no longer present.”

The Haisla are asking the JRP

that Northern Gateway is required to file evidence relating to the Kalamazoo Spill
which identifies the cause of the pipeline rupture and the extent to which
Enbridge’s pipeline maintenance, monitoring and response approach caused and
contributed to the volume of the spill by a date to be fixed by the Panel;

As for the upgrades, the Haisla notice of motion notes

Northern Gateway has identified additional design features, which it states will “enhance the safety and reliability of the pipelines over and above standard industry practice”. The design features identified in the Reply Evidence include increased wall thickness of the pipeline, additional increases in pipe thickness for crossings at major tributaries to the Fraser, Skeena and Kitimat River, the placement of remotely operated isolation valves on each side of major tributaries of the Fraser,Skeena and Kitimat Rivers, and dual remote monitoring systems ….
Northern Gateway has not provided any details relating to these proposed design
features. Their relevance and suitability to enhancing safety and reliability of the
pipelines cannot, therefore, be assessed.

The motion asks

that Northern Gateway is required to provide details of its proposed additional
design features for thicker pipes for the pipeline generally and at identified
watercourse crossings, for additional valve placements, and for additional remote
monitoring, as well as all studies and reports that support how these additional
design features enhance pipeline safety, by a date to be fixed by the Panel.

The Haisla motion also asks for more details on various environmental and other questions.

The Joint Review Panel has not yet ruled on the Haisla motion.

Enbridge responds to NTSB criticism in e-mail to northwest BC “community leaders”

Enbridge Northern Gateway has issued a detailed reply to the criticism of its operations contained in a preliminary report from the US National Transportation Safety Board to the 2010 oil spill at Marshall, Michigan, which called the company’s response like the silent movie era “Keystone cops.”

The note from Michele Parrett,  Senior Manager, Community and Municipal Relations for Northern Gateway was sent to members of the District of Kitimat Council and presumably other politicians and community leaders along the proposed pipeline route.

The document was among those routinely released to the public at the regular council meeting on Monday, July 16, 2012 and is a much more detailed defence of Enbridge’s position than the news release issued after the NTSB report.

In the e-mail, Enbridge says it has updated its safety and response procedures and its corporate culture since the Michigan incident.

Despite widespread criticism of Enbridge from all sides of the political spectrum, that NTSB report does not seem to have had any impact on federal Environment Minister Peter Kent, who told The Canadian Press had had not yet read the NTSB report. Kent also said that unread report will not change the Conservative government’s mind about the Northern Gateway pipeline project, adding “Pipelines are still, by far, the safest way to transport petrochemicals in any form.”

 


 Overview of NTSB Report  into Line 6B  incident at Marshall, Michigan

July 12, 2012

Dear Community Leader,

I’m writing you today to provide information regarding the United States’ National Transportation Safety Board’s (NTSB) release of its conclusions and recommendations yesterday, with regard to the Enbridge pipeline leak in Marshall, Michigan in July 2010.

Enbridge has not been waiting for the NTSB’s report before furthering to improve our safety standards. Since the incident we have undertaken our own internal investigation and incorporated the findings of that investigation into new practices and processes to improve our safety and reliability.

Enbridge and Enbridge Energy Partners has been working with the NTSB and other regulators throughout the course of the investigation so that we can take the necessary steps to prevent such an accident from occurring again. We are now reviewing the NTSB reports in detail to determine whether any further changes are required.

Enbridge has already implemented, in 2010 and 2011, appropriate operational and procedural changes based on its own detailed internal investigation. Enbridge’s overarching objective and business priority is to ensure the safety and reliability of our delivery systems for the people who live and work near our pipeline systems across North America, our employees and our customers.

In direct response to the Marshall accident, or as part of our ongoing improvement initiatives and activities, Enbridge has taken the following steps:

Pipeline and Facility Integrity

· Further heightened the importance of our pipeline and facility integrity program.

· Re-organized the functional areas that are responsible for pipeline and facility integrity.

· Substantially increased capital and operating budgets associated with maintenance and integrity programs.

· Undertook hundreds of internal inspections and thousands of investigative digs.

· Placed a renewed emphasis on the safety of our overall system.

Leak Detection

· Established the Pipeline Control Systems and Leak Detection department, doubling the number of employees and contractors dedicated to leak detection and pipeline control.

· Enhanced procedures for leak detection analysis.

· Updated control room management procedures.

· Implemented a Leak Detection Instrumentation Improvement Program to add and upgrade instrumentation across our system.

Pipeline Control and Control Centre Operations (CCO)

· Developed a Control Room Management (CRM) plan based on the U.S. Code of Federal Regulations and implemented a number of the sections, October 1, 2011, remaining sections implemented by August 1, 2012.

· Revised and enhanced all procedures pertaining to decision making, handling pipeline start-ups and shutdowns, leak detection system alarms, communication protocols, and suspected column separations.

· Changed organizational structures to better align, focus and manage employees’ span of control and workloads.

· Augmented CCO (Control Centre Operations) staff, adding training, engineering and operator positions.

· We also completed the design and construction of a new, world-class CCO in Edmonton, Alberta which was underway at the time of the accident.

Public Awareness

· Reviewed and strengthened Public Awareness Programs in the U.S. and Canada.

· Developing an industry-leading online and in-person training tool to provide Enbridge-specific information to emergency responders.

· In the U.S, we:

o Formalized the U.S. Public Awareness Committee.

o Improved the Program Effectiveness Evaluation process.

o Provided annual employee training for field employees across the company’s U.S. operations.

o Created a Public Awareness Hotline.

· In Canada, we:

o Formalized the Canadian Public Awareness Committee.

o Are creating a Canadian Public Awareness Database.

o Improved the landowner/tenant database.

o Developed a landowner newsletter.

o Established Community Relations positions in each region.

Emergency Response

· $50 million spent between 2012 and 2013 (projected) to improve our equipment, training and capabilities.

· Develop better tools for waterborne spills.

· In 2011, a cross-business unit response team was created for large-scale events requiring more resources that a single region could provide.

· In 2011, created a dedicated Emergency Response group in Operation Services for increased regional support.

· Conducting an Emergency Response preparedness assessment to enhance abilities to more rapidly respond and contain a significant release.

Safety Culture

· Reinforced a high level of safety and operational integrity across Enbridge in integrity management, third-party damage avoidance and detection, leak detection, incident response capacity, worker and contractor occupational safety, public safety and environmental protection.

· Implemented “Lifesaving Rules” and training for all Enbridge employees and contractors. The Lifesaving Rules are applicable to all employees and contractors, and are communicated, clarified and reinforced across all business units at Enbridge.

· Introduced new Safety Culture training sessions for all employees.

Over the past two years we have made significant improvements in the above areas. The NTSB’s findings will provide us with regulatory guidance and important information to help improve our performance and achieve our goal of zero spills.

We remain committed to a respectful, open and transparent review and discussion of the Northern Gateway Project. Should you have any questions, please do not hesitate to contact me or a member of the Northern Gateway team at the information provided below.

Sincerely,

Michele Perret

Senior Manager, Community and Municipal Relations

US National Transportation Safety Board summary report on Marshall, MI, Enbridge oil spill incident blames deficient management and training

The United States National Transportation Safety Board has issued a summary report on the rupture of the the Enbridge pipeline and subsequent oil spill at Marshall, Michigan, in 2010.

The report says that the probable cause of the oil spill  included deficient integrity management at Enbridge, which allowed previously known crack defects in corroded areas to spread until the pipeline failed; inadequate training of control center personnel by Enbridge, which allowed the rupture to remain undetected for 17 hours and insufficient public awareness and education, which allowed the release to continue for nearly 14 hours after the first notification of an odor to local emergency response agencies.

The full NTSB report will be issued in the coming weeks.

Enbridge responded in a news release that quoted outgoing Enbridge CEO Pat Daniel, who was in Washington for the release of the report:

“We very much appreciate the patience of residents in the communities who were affected by the Line 6B release,” said Patrick D. Daniel, Chief Executive Officer, Enbridge Inc. “Under the direction of the U.S. Environmental Protection Agency and local health authorities, the Kalamazoo River was re-opened last month for recreational use. We are also pleased to note that wildlife has returned to the area.”

“We believe that the experienced personnel involved in the decisions made at the time of the release were trying to do the right thing. As with most such incidents, a series of unfortunate events and circumstances resulted in an outcome no one wanted,” said Mr. Daniel.

Skeena Bulkley Valley Member of Parliament and NDP House Leader, Nathan Cullen, issued his own news release, saying, “Today’s report by the US National Transportation Safety Board (NTSB) into the deadly July 2010 Enbridge spill in Michigan identifies ‘a complete breakdown of safety at Enbridge’ and notes the company knowingly ‘failed to accurately assess the structural integrity of the pipeline.'”

“The findings are actually worse than we feared,” Cullen said. “They are a body blow of breathtaking proportions to Enbridge and yet another wake-up call to the Northwest of the dangers of allowing big oil to run a pipeline through our Northwest watersheds.”

Cullen commended NTSB chair Deborah Hersman for her frankness in terming Enbridge’s Michigan spill “”an accident that is a wake-up call to the industry, the regulator, and the public.”

Here is the complete summary as posted on the NTSB website

Enbridge, Inc. Hazardous Liquid Pipeline Rupture

July 25, 2010
Marshall, MI

NATIONAL TRANSPORTATION SAFETY BOARD
Public Meeting of July 10, 2012
(Information subject to editing)
NTSB/PAR-12/01

This is a synopsis from the National Transportation Safety Board’s report and does not include the NTSB’s rationale for the conclusions, probable cause, and safety recommendations. Safety Board staff is currently making final revisions to the report from which the attached conclusions and safety recommendations have been extracted. The final report and pertinent safety recommendation letters will be distributed to recommendation recipients as soon as possible. The attached information is subject to further review and editing.

Executive Summary

On Sunday, July 25, 2010, at 5:58 p.m., eastern daylight time, a segment of a 30-inch-diameter pipeline (Line 6B), owned and operated by Enbridge Incorporated (Enbridge) ruptured in a wetland in Marshall, Michigan. The rupture occurred during the last stages of a planned shutdown and was not discovered or addressed for over 17 hours. During the time lapse, Enbridge twice pumped additional oil (81 percent of the total release) into Line 6B during two startups; the total release was estimated to be 843,444 gallons of crude oil. The oil saturated the surrounding wetlands and flowed into the Talmadge Creek and the Kalamazoo River. Local residents self-evacuated from their houses, and the environment was negatively affected. Cleanup efforts continue as of the adoption date of this report, with continuing costs exceeding $767 million. About 320 people reported symptoms consistent with crude oil exposure. No fatalities were reported.

Conclusions

1. The following were not factors in this accident: cathodic protection, microbial corrosion, internal corrosion, transportation-induced metal fatigue, third-party damage, and pipe manufacturing defects.

2. Insufficient information was available from the postaccident alcohol testing; however, the postaccident drug testing showed that use of illegal drugs was not a factor in the accident.

3. Had the firefighters discovered the ruptured segment of Line 6B and called Enbridge, the two startups of the pipeline might not have occurred and the additional volume might not have been pumped.

4. The Line 6B segment ruptured under normal operating pressure due to corrosion fatigue cracks that grew and coalesced from multiple stress corrosion cracks, which had initiated in areas of external of corrosion beneath the disbonded polyethylene tape coating.

5. Title 49 Code of Federal Regulations 195.452(h) does not provide clear requirements regarding when to repair and when to remediate pipeline defects and inadequately defines the requirements for assessing the effect on pipeline integrity when either crack defects or cracks and corrosion are simultaneously present in the pipeline.

6. The Pipeline and Hazardous Materials Safety Administration (PHMSA) failed to pursue findings from previous inspections and did not require Enbridge Incorporated (Enbridge) to excavate pipe segments with injurious crack defects.

7. Enbridge’s delayed reporting of the “discovery of condition” by more than 460 days indicates that Enbridge’s interpretation of the current regulation delayed the repair of the pipeline.

8. Enbridge’s integrity management program was inadequate because it did not consider the following: a sufficient margin of safety, appropriate wall thickness, tool tolerances, use of a continuous reassessment approach to incorporate lessons learned, the effects of corrosion on crack depth sizing, and accelerated crack growth rates due to corrosion fatigue on corroded pipe with a failed coating.

9. To improve pipeline safety, a uniform and systematic approach in evaluating data for various types of in-line inspection tools is necessary to determine the effect of the interaction of various threats to a pipeline.

10. Pipeline operators should not wait until PHMSA promulgates revisions to 49 Code of Federal Regulations 195.452 before taking action to improve pipeline safety.

11. PII Pipeline Solutions’ analysis of the 2005 in-line inspection data for the Line 6B segment that ruptured mischaracterized crack defects, which resulted in Enbridge not evaluating them as crack-field defects.

12. The ineffective performance of control center staff led them to misinterpret the rupture as a column separation, which led them to attempt two subsequent startups of the line.

13. Enbridge failed to train control center staff in team performance, thereby inadequately preparing the control center staff to perform effectively as a team when effective team performance was most needed.

14. Enbridge failed to ensure that all control center staff had adequate knowledge, skills, and abilities to recognize and address pipeline leaks, and their limited exposure to meaningful leak recognition training diminished their ability to correctly identify the cause of the Material Balance System (MBS) alarms.

15. The Enbridge control center and MBS procedures for leak detection alarms and identification did not fully address the potential for leaks during shutdown and startup, and Enbridge management did not prohibit control center staff from using unapproved procedures.

16. Enbridge’s control center staff placed a greater emphasis on the MBS analyst’s flawed interpretation of the leak detection system’s alarms than it did on reliable indications of a leak, such as zero pressure, despite known limitations of the leak detection system.

17. Enbridge control center staff misinterpreted the absence of external notifications as evidence that Line 6B had not ruptured.

18. Although Enbridge had procedures that required a pipeline shutdown after 10 minutes of uncertain operational status, Enbridge control center staff had developed a culture that accepted not adhering to the procedures.

19. Enbridge’s review of its public awareness program was ineffective in identifying and correcting deficiencies.

20. Had Enbridge operated an effective public awareness program, local emergency response agencies would have been better prepared to respond to early indications of the rupture and may have been able to locate the crude oil and notify Enbridge before control center staff tried to start the line.

21. Although Enbridge quickly isolated the ruptured segment of Line 6B after receiving a telephone call about the release, Enbridge’s emergency response actions during the initial hours following the release were not sufficiently focused on source control and demonstrated a lack of awareness and training in the use of effective containment methods.

22. Had Enbridge implemented effective oil containment measures for fast-flowing waters, the amount of oil that reached Talmadge Creek and the Kalamazoo River could have been reduced.

23. PHMSA’s regulatory requirements for response capability planning do not ensure a high level of preparedness equivalent to the more stringent requirements of the U.S. Coast Guard and the U.S. Environmental Protection Agency.

24. Without specific Federal spill response preparedness standards, pipeline operators do not have response planning guidance for a worst-case discharge.

25. The Enbridge facility response plan did not identify and ensure sufficient resources were available for the response to the pipeline release in this accident.

26. If PHMSA had dedicated the resources necessary and conducted a thorough review of the Enbridge facility response plan, it would have disapproved the plan because it did not adequately provide for response to a worst-case discharge.

27. Enbridge’s failure to exercise effective oversight of pipeline integrity and control center operations, implement an effective public awareness program, and implement an adequate postaccident response were organizational failures that resulted in the accident and increased its severity.

28. Pipeline safety would be enhanced if pipeline companies implemented safety management systems.

Probable Cause

The National Transportation Safety Board (NTSB) determines that the probable cause of the pipeline rupture was corrosion fatigue cracks that grew and coalesced from crack and corrosion defects under disbonded polyethylene tape coating, producing a substantial crude oil release that went undetected by the control center for over 17 hours. The rupture and prolonged release were made possible by pervasive organizational failures at Enbridge Incorporated (Enbridge) that included the following:

  • Deficient integrity management procedures, which allowed well-documented crack defects in corroded areas to propagate until the pipeline failed.
  • Inadequate training of control center personnel, which allowed the rupture to remain undetected for 17 hours and through two startups of the pipeline.
  • Insufficient public awareness and education, which allowed the release to continue for nearly 14 hours after the first notification of an odor to local emergency response agencies.

 

Contributing to the accident was the Pipeline and Hazardous Materials Safety Administration’s (PHMSA) weak regulation for assessing and repairing crack indications, as well as PHMSA’s ineffective oversight of pipeline integrity management programs, control center procedures, and public awareness.

Contributing to the severity of the environmental consequences were (1) Enbridge’s failure to identify and ensure the availability of well-trained emergency responders with sufficient response resources, (2) PHMSA’s lack of regulatory guidance for pipeline facility response planning, and (3) PHMSA’s limited oversight of pipeline emergency preparedness that led to the approval of a deficient facility response plan.

Recommendations

To the U.S. Secretary of Transportation:

1. Audit the Pipeline and Hazardous Materials Safety Administration’s onshore pipeline facility response plan program’s business practices, including reviews of response plans and drill programs, and take appropriate action to correct deficiencies.

2. Allocate sufficient resources as necessary to ensure that the Pipeline and Hazardous Materials Safety Administration’s onshore pipeline facility response plan program meets all of the requirements of the Oil Pollution Act of 1990.

To the Pipeline and Hazardous Materials Safety Administration:

3. Revise Title 49 Code of Federal Regulations 195.452 to clearly state (1) when an engineering assessment of crack defects, including environmentally assisted cracks, must be performed; (2) the acceptable methods for performing these engineering assessments, including the assessment of cracks coinciding with corrosion with a safety factor that considers the uncertainties associated with sizing of crack defects; (3) criteria for determining when a probable crack defect in a pipeline segment must be excavated and time limits for completing those excavations; (4) pressure restriction limits for crack defects that are not excavated by the required date; and (5) acceptable methods for determining crack growth for any cracks allowed to remain in the pipe, including growth caused by fatigue, corrosion fatigue, or stress corrosion cracking as applicable.

4. Revise Title 49 Code of Federal Regulations 195.452(h)(2), the “discovery of condition,” to require, in cases where a determination about pipeline threats has not been obtained within 180 days following the date of inspection, that pipeline operators notify the Pipeline and Hazardous Materials Safety Administration and provide an expected date when adequate information will become available.

5. Conduct a comprehensive inspection of Enbridge Incorporated’s integrity management program after it is revised in accordance with Safety Recommendation (11).

6. Issue an advisory to all hazardous liquid and natural gas pipeline operators describing the circumstances of the accident in Marshall, Michigan—including the deficiencies observed in Enbridge Incorporated’s integrity management program—and ask them to take appropriate action to eliminate similar deficiencies.

7. Develop requirements for team training of control center staff involved in pipeline operations similar to those used in other transportation modes.

8. Extend operator qualification requirements in Title 49 Code of Federal Regulations 195 Subpart G to all hazardous liquid and gas transmission control center staff involved in pipeline operational decisions.

9. Amend Title 49 Code of Federal Regulations Part 194 to harmonize onshore oil pipeline response planning requirements with those of the U.S. Coast Guard and the U.S. Environmental Protection Agency for facilities that handle and transport oil and petroleum products to ensure that pipeline operators have adequate resources available to respond to worst-case discharges.

10. Issue an advisory bulletin to notify pipeline operators (1) of the circumstances of the Marshall, Michigan, pipeline accident, and (2) of the need to identify deficiencies in facility response plans and to update these plans as necessary to conform with the nonmandatory guidance for determining and evaluating required response resources as provided in Appendix A of Title 49 Code of Federal Regulations 194, “Guidelines for the Preparation of Response Plans.”

To Enbridge Incorporated:

11. Revise your integrity management program to ensure the integrity of your hazardous liquid pipelines as follows: (1) implement, as part of the excavation selection process, a safety margin that conservatively takes into account the uncertainties associated with the sizing of crack defects from in-line inspections; (2) implement procedures that apply a continuous reassessment approach to immediately incorporate any new relevant information as it becomes available and reevaluate the integrity of all pipelines within the program; (3) develop and implement a methodology that includes local corrosion wall loss in addition to the crack depth when performing engineering assessments of crack defects coincident with areas of corrosion; and (4) develop and implement a corrosion fatigue model for pipelines under cyclic loading that estimates growth rates for cracks that coincide with areas of corrosion when determining reinspection intervals.

12. Establish a program to train control center staff as teams, semiannually, in the recognition of and response to emergency and unexpected conditions that includes supervisory control and data acquisition system indications and Material Balance System software.

13. Incorporate changes to your leak detection processes to ensure that accurate leak detection coverage is maintained during transient operations, including pipeline shutdown, pipeline startup, and column separation.

14. Provide additional training to first responders to ensure that they (1) are aware of the best response practices and the potential consequences of oil releases and (2) receive practical training in the use of appropriate oil-containment and -recovery methods for all potential environmental conditions in the response zones.

15. Review and update your oil pipeline emergency response procedures and equipment resources to ensure that appropriate containment equipment and methods are available to respond to all environments and at all locations along the pipeline to minimize the spread of oil from a pipeline rupture.

16. Update your facility response plan to identify adequate resources to respond to and mitigate a worst-case discharge for all weather conditions and for all your pipeline locations before the required resubmittal in 2015.

To the American Petroleum Institute:

17. Facilitate the development of a safety management system standard specific to the pipeline industry that is similar in scope to your Recommended Practice 750, Management of Process Hazards. The development should follow established American National Standards Institute requirements for standard development.

To the Pipeline Research Council International, Inc.:

18. Conduct a review of various in-line inspection tools and technologies—including, but not limited to: tool tolerance, the probability of detection, and the probability of identification—and provide a model with detailed step-by-step procedures to pipeline operators for evaluating the effect of interacting corrosion and crack threats on the integrity of pipelines.

To the International Association of Fire Chiefs and the National Emergency Number Association:

19. Inform your members about the circumstances of the Marshall, Michigan, pipeline accident and urge your members to aggressively and diligently gather from pipeline operators system-specific information about the pipeline systems in their communities and jurisdictions.

Previous Recommendation Reiterated in this Report

To the Pipeline and Hazardous Materials Safety Administration:

Require operators of natural gas transmission and distribution pipelines and hazardous liquid pipelines to provide system-specific information about their pipeline systems to the emergency response agencies of the communities and jurisdictions in which those pipelines are located. This information should include pipe diameter, operating pressure, product transported, and potential impact radius. (P-11-8)

A live and archived webcast of the proceedings will be available at http://www.capitolconnection.net/capcon/ntsb/ntsb.htm. To report any difficulties viewing the webcast, please call 703-993-3100 and ask for webcast technical support.

The complete report will appear on ntsb.gov in several weeks.

In its response, Enbridge went on to say:

“Safety has always been core to our operations. Our intent from the beginning of this incident has been to learn from it so we can prevent it from happening again, and to also share what we have learned with other pipeline operators,” said Stephen J. Wuori, President, Liquids Pipelines, Enbridge Inc. “Enbridge and EEP conducted a detailed internal investigation of this incident in the months following the release and have made numerous enhancements to their processes, procedures and training as a result of the findings of the investigation, including in the control center. Incident prevention, detection and response have also been enhanced. We will carefully examine the findings in the NTSB report to determine whether any further adjustments are appropriate.”

Enbridge  says it has e worked closely and cooperatively with the NTSB throughout its investigation.  The company isnow reviewing the summary report and  will not comment specifically on the contents of the Final Report until it is released by the NTSB Board and analysis of the report has been completed.

US Pipeline and Hazardous Material Safety Admin cites Enbridge for violations in Kalamazoo spill, wants $3.7 million fine

Updated with Enbridge statement

The United States Pipeline and Hazardous Materials Safety Administration today cited Enbridge for a series of violations in connection with the pipeline rupture and bitumen spill at Mashall, Michigan,  in 2010 and is proposing the company be fined a record $3.7 million.

A letter issued today, July 2, 2012, from the PMHSA  to Richard Adams, Vice President, U.S. Operations, Enbridge Energy Limited Partnership, lists a series of alleged failures by Enbridge.

The letter says the investigation began on July 26, 2010, the day after the Enbridge Energy Limited Partnership’s 30-inch diameter Line 6B pipeline ruptured near Marshall, Michigan on July 25, spilling 20,000 barrels of crude and contaminating 38 miles of the Kalamazoo River.

That investigation, the letter says, turned up numerous violations of US regulations including, safety rules, faulty risk analysis, failure to follow proper operation and management procedures and problems with reporting and operator qualification requirements.

The PHMSA alleges that Enbridge violated 24 regulations for pipeline safety and procedures, with civil penalties ranging from $41,200 to $1,000,000 for a total of $3.7 million.

None of the allegations have been proven and Enbridge is free to contest the filings and allegations and ask for a hearing.

In a news release, Enbridge responded:

Enbridge appreciates the hard work and due diligence that PHMSA has put into this investigation,” said Stephen J. Wuori, President, Liquids Pipelines, Enbridge Inc. “Safety has always been core to our operations. Enbridge completed a detailed internal investigation of this incident in the fall of 2010 and has made numerous enhancements to the processes and procedures in our control center since the Line 6B accident, including the training provided to pipeline operators, and has made significant changes in this critical component of our operations. Incident prevention, detection and response have also been enhanced. We will carefully examine the NOPV to determine whether any further adjustments are appropriate.

The letter says the investigation began on July 26, 2010, the day after the Enbridge Enbridge Energy Limited Partnership’s 30-inch diameter Line 6B pipeline ruptured near Marshall, Michigan on July 25, spilling 20,000 barrels of crude and contaminating 38 miles of the Kalamazoo River.

That investigation, the letter says, turned up numerous violations of US regulations including, safety rules, faulty risk analysis, failure to follow proper operation and management procedures and problems with reporting and operator qualification requirements.

The letter also outlines what happened during the spill, as seen through the eyes of PHMSA investigators.

According to the letter, the Enbridge pipeline failed despite a series of In-Line Inspections that the company had performed on the pipeline. Those inspections, the PHMSA investigators say found “multiple corrosion and crack-like anomalies on the pipe joint that failed on July
25, 2010.” It is alleged that Enbridge did not conduct any field examination of the reported anomalies before the accident.

According to the PHMSA, there was actually a crack detection being performed on Line 6B on the day of the failure and the testing equipment was left in the pipeline until the after the line was restarted on September 27, 2010.

The reports says the Michigan pipeline ruptured at 17:58 EDT on July 25, 2010, approximately 0.6 miles downstream of the company’s Marshall pumping station. At the time, Enbridge’s Edmonton Control Center  (CCO) was in the process of starting a scheduled 10-hour shutdown of the pipeline.

The PHMSA report says:

as soon as the failure occurred, the CCO received multiple alarms and indications of abnormal operations on Line 6B, but the company did not execute its suspected-leak or emergency procedures. Instead, Enbridge allowed the pipeline to remain idle as part of the Scheduled Shutdown for approximately 10 hours, during which time a new shift came on duty at the CCO, which brought in a new set of controllers, supervisors, and support personnel.

At approximately 04:00, on July 26, 2010, Enbridge initiated the scheduled start-up of Line 6B … Within minutes, the CCO received multiple alarms and indications of abnormal operating conditions, which indicated that the pressure at the Marshall pumping station had not increased as expected and the imbalance between the volume of product injected into the pipeline and the volume of product being delivered from the pipeline exceeded established thresholds. Again, Enbridge did not execute its suspected leak or emergency procedures. Instead, Enbridge continued to pump crude oil into the line while the controller, supervisors, and support personnel evaluated the situation.

After an hour, the Edmonton control centre abandoned the attempted restart and shut down the pipeline. During the time Enbridge was trying to restart the pipeline, an additional 10,460 barrels of crude oil was injected into the pipeline.

The PHMSA report says that the Enbridge control room was monitoring the “lack of typical pressure and flow conditions for this pipeline configuration and alarms.” Control room supervisors contacted managers and the decision was made to restart the pipeline a second time, which began at 0720 on July 26.

Again the Enbridge control “received multiple alarms and indications of abnormal
operating conditions.”

Enbridge continued to pump oil for another 31 minutes sending 5,831 barrels of oil into the pipeline.

By this time supervisors and managers were discussing the possibility of a suspected leak but no one activated Enbridge’s spill procedures. The second restart was halted at 0751 at which time a new shift took over the control room.

Enbridge managers “discussed the two restart attempts, resulting in the Line 6B controller
conducting further investigation into the historical operating information on the line but
taking no action to deal with a spill.”

It was three hours and fifteen minutes after the shift change, at 11:18 on July 26, roughly 17 hours after the failure occurred, that the Enbridge control room received an emergency call from an employee of a local gas company, Consumers Energy, reporting oil in a creek near Marshall, Michigan.

It was at that point that Enbridge closed remotely operated valves on each side of the reported leak, isolating three miles of pipeline on either side of the rupture. It was then that Enbridge activated its emergency procedure and field personnel were sent to the scene. The field personnel confirmed the spill to the Edmonton control room at 11:43.

On July 28, the Pipeline and Hazardous Materials Safety Administration issued “a Corrective Action Order” to Enbridge requiring the company to take action to protect the public, property, and the environment. “Amongst other things, the Corrective Action Order required a pressure reduction, verification of pipeline integrity, integration of information, and provisions for ensuring ongoing safe operation considering all risk factors.”

The letter then cites Enbridge for the following alleged violations:

Pipeline integrity management in high consequence areas

The letter says that after an integrity assessment of Line 6B, Enbridge failed to obtain, within 180 days, sufficient information about anomalous conditions presenting a potential threat to the integrity of Line 6B. Enbridge conducted a high-resolution integrity assessment of Line 6B on October 13, 2007 and received the “vendor report” on June 4, 2008. The citation says “The 180 day deadline was April 10, 2008. Enbridge did not demonstrate that the 180 day period was impracticable.”

The report says Enbridge implemented pressure restrictions on the pipeline on July 17, 2009, approximately 462 days after the deadline to have sufficient information to identify anomalous conditions. A year later, according to the PHMSA, Enbridge submitted a “Long Term Pressure Reduction Notification” to PHMSA on July 15, 2010. The date of discovery was reported by Enbridge as July 17, 2009 not June 2008.

US regulations require pipeline companies to fix “corrosion anomalies” in pipelines with 180 days. The citation says that starting back as far as 2004, Enbridge “did not schedule remediation of
corrosion anomalies involving the longitudinal weld seam of pipe joint #217720, that is the joint that eventually ruptured causing the spill. The report says Enbridge also did not remediate crack-like anomalies on the same pipe joint… that could impair the integrity of the pipeline” and “Enbridge could not demonstrate that the company attempted or scheduled any remediation of the corrosion or crack anomalies that were identified by the assessments” nor did Enbridge schedule that joint for excavation prior to the rupture.

Risk analysis

The PHMSA alleges that Enbridge failed to consider all relevant risk factors associated with the determination of the amount of product that could be released from a rupture on the pipeline. Enbridge’s risk analysis process also assumed a pipeline rupture of this magnitude would be identified by its leak detection instrumentation within five minutes, and that it would take an additional three minutes to close remotely operated valves on either side of the rupture.

Before the spill, Enbridge had estimated the worst case scenario at the that location would be a release 1,670 barrels initially with another 1938 barrels released during “drain down” for a total of3,608 barrels

The actual failure scenario demonstrates the rupture was not recognized by Enbridge, and the isolation valves were not closed, until approximately 17 hours after it occurred. An additional 16,431 barrels of product was injected into the ruptured pipeline, causing the total spill volume to greatly exceed Enbridge’s worst case discharge scenario for this location.

Evaluation

The PHMSA letter alleges that “Enbridge did not properly consider the results of corrosion and cracking assessments nor did Enbridge integrate the information from these assessments to
properly assure overall pipeline integrity.”

While the investigation revealed that while “Enbridge has a long history of performing
integrity assessments” those assessment results “were evaluated independently and not integrated in a fashion that assures pipeline integrity.”

General Requirements

The PHMSA says US regulations require that whenever an operator discovers any condition that could adversely affect the safe operation of its pipeline system, “it shall correct it within a
reasonable time,” adding that “if the condition is of such a nature that it presents
an immediate hazard to persons or property, the operator may not operate the affected part of the system until it has corrected the unsafe condition.”

The letter says” “Enbridge failed to correct a condition that could affect the safe operation of a
pipeline within a reasonable time following discovery. Enbridge discovered the
condition as a result of …. instrumentation alarms and events that alerted
within seconds and minutes of the rupture…”

Since the alarms would have indicated conditions that could adversely affect the safe operation of the pipeline,” the PHMSA says: “The expected initial corrective action is to notify appropriate company and emergency response personnel to investigate and mitigate the effects of any unsafe conditions. This was not done until approximately 17 hours after discovery of the conditions.”

The letter says Enbridge did not follow established written procedures for responding to,
investigating, and correcting the cause of pressure outside of normal operating
limits during the shutdown and Enbridge did not notify responsible personnel in accordance with
the procedure. It says that Enbridge has not developed a specific written procedure for responding to an Invalid Pressure Alarm, but has instead developed a written procedure for required actions based on alarm severity.

For an S6-Severe Alarm, the procedures require the controller to: (1) Notify the Shift Lead; (2) Advise on site/on-call personnel; (3) Create a F ACMAN (Enbridge term for Facility Management record-keeping system used to documents abnormal operating conditions).

The PHMSA says “Enbridge failed to take any of these required actions.”

It goes on to allege that Enbridge did not follow established written procedures for responding to,
investigating, and correcting the cause of pressure in the pipeline that were outside of normal operating limits and goes on to say that Enbridge has not developed a specific written procedure for responding to a Low Suction Pressure Alarm.

As in the previous case, Enbridge’s procedures were based on “alarm severity.”

For an S4-Warning Alarm, the procedures require (1) Discretionary controller response to alarm dependent on operating conditions, (2) Notify the Shift Lead if unsure of response, (3) If multiple S4 alarms are active for a related issue, the response and severity may be raised, ( 4) FACMAN creation may be required, (5) Advise on-site/on-call personnel if required.

Again the PHMSA alleges: “ Enbridge did not take any of the above actions, or any
other actions, in response to this alarm. The fact the Marshall suction pressure
abruptly dropped to 0 psig, which was unexpected and abnormal, dictates followup
investigative actions in accordance with the procedure, in order to determine
the reason/source of the alarm.”

The report says that Enbridge did not follow established written procedures for responding to, investigating, and correcting the cause of an unintended shutdown at the Marshall Unit and Enbridge also did not notify responsible personnel in accordance with the procedure.

Emergencies

The PHMSA says Enbridge did not take necessary action to minimize the volume of hazardous
liquid released in the event of a failure or notify police during an emergency, even though that was required by Enbridge’s own emergency notification procedures, saying that the shift lead in the Edmonton control room should have initiated the procedures at 18:03, on July 25, when an alarm went off.

Enbridge policy on leak “triggers” that is “unexplained abnormal operating conditions or events that indicate a leak” requires that a number of procedure be started once a leak trigger is detected. The PHMA says neither the suspected leak or confirmed leaks procedures were executed by the Edmonton control room nor were managers, field personnel and local police notified.

Public Awareness

The PHMSA letter says that Enbridge did not evaluate the effectiveness of its public awareness program in accordance with the written procedures. The company’s plan calls on the public awareness manager to “informally assess the effectiveness of public awareness efforts” each year, but the PHMSA says “Enbridge could not demonstrate this was being performed.”

The investigation identified a number of instances where actions taken by members of the PAP target audience were not in accordance with the program message (e.g. not associating the odour with that of a possible crude oil release, not contacting Enbridge’s Emergency Number in response to the odour complaints, and entry into the spill area by untrained individuals).

The release resulted in a number of local residents being displaced, contamination of approximately 38 miles of the Kalamazoo River, and contamination of affected fish and wildlife.

Accident reporting

The PHMSA also alleges that Enbridge failed to properly report the incident to the proper authorities, in this case the US Department of Transportation. It says Enbridge failed to accurately report the time of failure and other significant facts relevant to the extent of damages associated with a pipeline rupture which occurred at 17:58, on July 25, 2010. According to the PHMSA, Enbridge incorrectly reported the time the accident was discovered as 09:45 July 26 and also reported the material had not reached the Kalamazoo River yet, and that the release was secured.

According to the letter, investigative interviews show that the Edmonton control room personnel were aware that there were abnormal conditions on the pipeline, that “the rupture had likely occurred when the pipeline was shutdown, the night before” that “the release was not secured, as oil was moving down the Kalamazoo River. The impacts to people, property, and the environment were immediately obvious when emergency response actions were initiated.” The letter says that Enbridge did not file follow up reports to augment the initial report to Department of Transportation nor did it “currently available accident information” to the DOT within 30 days.

A report filed by Enbridge on August 25, 2010, again misreported the time of the spill, now calling it “11:41 on July 26, 2010, when it had been clear within hours of discovery that the failure date and time was approximately 17:58 on July 25, 2010.” It goes on to say that Enbridge report “also did not indicate the number of general public evacuated, even though daily EPA Pollution Reports indicated the number of residences that were evacuated, and Enbridge paid for alternative lodging for these evacuees as necessary.” It also alleges that some of the technical details in that August report on pipeline pressure were inaccurate and goes on to say that some subsequent reports filed by Enbridge were inaccurate although “the correct information has been known by the operator for some time.”

One example was that a witness told investigators on December 5, 2011 indicated that Enbridge determined the total costs of damages associated with the Line 6B rupture were currently $720
million but the value reported in a report filed on February 22, 2011 report was $550 million. The PHMSA says: “It is unknown at what point the $720 million value was determined by Enbridge, but the reported value was not updated until March 6, 2012, approximately 3 months after the interview.”

Employee qualifications

The PHMSA report alleges that Enbridge allowed an “unqualified individual to perform covered tasks (operating a pipeline) without direct observation by a qualified individual.” It says a previously qualified controller, who had been off duty for an extended period of time, was operating the pipeline console, and a qualified controller was assigned to oversee the operations.

According to the investigation “the qualified pipeline controller, even though seated adjacent to the un-qualified pipeline controller, was performing other tasks, and not directing and observing line operations, as required by the written procedures.” The report says that after multiple alarms went off “the unqualified pipeline controller did not respond to the alarms in full accordance with the operator’s written procedures, and the qualified pipeline controller’s oversight of the operations was insufficient to ensure that the required actions were taken.

In its news release, Enbridge added:

Enbridge has worked closely and cooperatively with all federal and state agencies, including PHMSA and the National Transportation Safety Board (NTSB) throughout the investigation of the Line 6B accident, and is now reviewing the NOPV in detail. Enbridge will not comment specifically on the contents of the NOPV until it completes that analysis.

On June 18, 2012, Lorraine Little, Enbridge senior manager of US public affairs, liquids operations and projects,  appeared before District of Kitimat Council. At that time, Little outlined how the company was working on clean up operations. She also said Enbridge had improved its operations and emergency response since the Michigan incident but would not go into detail, due to ongoing investigations and litigation in the United States.
