PART TWO: What the State Dept. Keystone EIS says about Kinder Morgan and Vancouver harbour

The US State Department report on the controversial Keystone XL pipeline project also looks at the Kinder Morgan Transmountain pipeline (both the existing line and the proposed second line) and, in at least one part of the report, seems to speculate that, once expansion of the Panama Canal is completed in 2014, there could be larger tankers in Vancouver harbour, something that up until now, both Kinder Morgan and Port Metro Vancouver have denied. However, the State Department report does not say how the port of Vancouver could handle larger tankers.

The State Department EIS says if larger tankers were loaded at Vancouver, it could be economic for crude from the Kinder Morgan Transmountain pipeline to be moved to the US Gulf Coast.

Using heavy crude as a basis, a present day movement via Trans Mountain to Vancouver and thence on a Panamax tanker via the Panama Canal to Houston would have a total freight cost (pipeline tariff plus tanker freight and Panama toll) of around $8.50-9.50/barrel (bbl).

Recognizing that Kinder Morgan plans to enable future shipment in larger Suezmax tankers, and that the Panama Canal Authority is expanding the Canal to take tankers of that size, the rate using a Suezmax would be approximately $1/bbl lower. These rates compare to approximately $8/bbl to move heavy crude via pipeline from Hardisty to Houston. Thus, while in normal markets, a tanker movement from Western Canada would be somewhat more costly than via pipeline, in a scenario where ability to move WCSB crudes by pipeline to the U.S. Gulf Coast were constrained, refiners in the U.S. Gulf Coast could opt for tanker transport.

(The Panama Canal expansion program began in 2006 and is scheduled for completion in 2014)

Latest progress report (pdf)

According to the progress report the current Panama Canal has the capacity for ships that are 32.3 metres wide by 304.6 metres long, This will increase to 49 metres wide by 366 metres long.

Later in the report the State Department goes on to say that bitumen and crude could, as an alternative to Keystone, go to Vancouver:

Under this option, WCSB [Western Canada Sedminetary Basin] would be shipped by existing railways or new pipelines from the Hardisty region to Vancouver or Kitimat, British Columbia for shipment by marine transport through the expanded Panama Canal and delivery to Gulf Coast area refiners. This option considers moving up to 730,000 bpd of heavy crude to the Port of Vancouver and then to the marine docks at the Westridge marine terminal in Vancouver or the port in Kitimat. Under this option, crude oil could move either via rail or by a new pipeline from the Hardisty region.

Currently, Kinder Morgan is planning an expansion of the existing Trans Mountain pipeline originating at Edmonton, increasing its capacity from 300,000 bpd (current) to up to 890,000 bpd(planned for operations in 2017).

The Trans Mountain pipeline runs into Vancouver via the existing Burnaby terminal over to the Westridge dock for loading heavy crude onto vessels. The pipeline has sufficient commitment from shippers to proceed with engineering and permitting processes. Kinder Morgan indicates that the project would significantly increase tanker traffic from about 5 to 34 cargoes per month, or up to about 400 cargoes per year . The increased marine traffic is due to increased volume to be shipped, and lack of sufficient channel draft to load larger vessels.

Kinder Morgan on its website says

The proposed expansion at Westridge Terminal is based on the loading of Aframax tankers, the same tankers currently being loaded at Westridge. Larger tankers are not permitted in the Vancouver harbour, and are not under consideration for the expansion. Proposed changes at the dock include new loading facilities, fire protection, vapour recovery, secondary containment, and emergency response equipment.

To connect the Burnaby Terminal with the Westridge Terminal, the proposed expansion includes two new, four-kilometre pipelines each with a diameter of 762 millimeters (30 inches). These two new delivery lines would provide product deliveries to tankers at two new dock berths, and provide the scheduling flexibility required for a marine operation.

Port Metro Vancouver also says on its website:

The role of Port Metro Vancouver is to conduct a rigorous project review to ensure the safe movement of goods through the Port. Kinder Morgan has yet to submit a formal project proposal to Canada’s National Energy Board. If they do, and should approval be granted, the project would then undergo several other permitting processes, one of which is a Port Metro Vancouver Project Permit Review. Vancouver is a very low volume tanker port. Currently, there are about 100 crude oil and chemical tankers calling the port each year. If the Kinder Morgan project receives approval, that number could increase to approximately 400 tankers a year. Other well-run ports such as the Port of Rotterdam handles 8,206 tankers a year, while Singapore handle 22,280 tankers a year.

Will larger tankers be calling at Port Metro Vancouver as a result of the Kinder Morgan Proposal?

There are no plans to exceed the current maximum size of tankers calling at Port Metro Vancouver. Due to depth restrictions in the Burrard Inlet, the largest dimension of tanker that can be handled is the Aframax, a medium-sized tanker with a maximum capacity of 120,000 tonnes. Even then, these vessels can load to only around 80% of capacity due to draft restrictions.

 

The State Department EIS was cautious about the Kinder Morgan project and did not do the same deailed analysis as it did for Prince Rupert.

The substantial increase in tanker traffic from the proposed Kinder Morgan expansion has raised safety and environmental concerns. Moving additional volumes of crude oil from the proposed Project into the Vancouver market by either a new pipeline or rail would result in 400 or more additional vessels loading at Vancouver each year and would require considerably more storage to be built than the current Kinder Morgan operations. The expansion of storage capacity, potential rail off-loading facilities and logistics, and increased marine traffic may make this option logistically challenging in a relatively compressed and populated geographical area.

Moreover, even if a separate pipeline from Hardisty could be planned, mapped, engineered, designed, and permitted starting today, it would likely not be available as an option until well after the proposed [Keytsone] Project’s planned start date. As a result of the logistical challenges in increasing the amounts of heavy Canadian grades of crude oil coming into the Vancouver/Burnaby region over and above the volumes from the Kinder Morgan expansion, this option was deemed to be less viable than movements from Kitimat and Prince Rupert and was eliminated from detailed analysis.

It’s not clear from the Keystone EIS, if the State Department was simply speculating on larger tankers in Vancouver harbour or if it was made of aware of possible hopes for a deep water tanker port elsewhere in the Vancouver harbour area.

The State Department EIS goes on to note:

While no new additional pipeline capacity has been added from Canada into the United States or to the Canadian West Coast since the Final EIS in 2011, a number of projects are proposed, including this proposed Project. The 300,000 bpd Kinder Morgan Trans Mountain pipeline that runs from Edmonton to the British Columbia coast at Vancouver, with a spur to Washington State refineries, has been over-subscribed for some time. A successful open season led the Kinder Morgan to announce and file for expansion to 750,000 bpd by potentially 2017. After a
second open season, Kinder Morgan has increased the expansion to 890,000 bpd. The bulk of the incremental crude moved on the line would potentially be destined for Asia. The review process for this project is continuing, but there is significant opposition based on concerns over environmental impacts associated with the oil sands and with additional tanker movements in the Port Vancouver harbor.

As noted above, both of these proposed pipeline projects to Canada’s West Coast face significant resistance and uncertainty, but there are strong cost advantages when compared with moving WCSB crude to the Gulf Coast even if rail were used to access the Canadian West Coast... In fact, using rail and tanker to ship crude oil from the WCSB via the West Coast to China is comparable to the pipeline rate to reach the U.S. Gulf Coast. An increase in the transport costs to the Gulf Coast (utilizing alternative transport options such as rail) would have a tendency to increase the economic incentive to utilize any West Coast export options, if they are available.

PART THREE: Keystone EIS looks in-depth at the railway to Prince Rupert option for bitumen and crude

There have always been commentators who believe that if the Northern Gateway Pipeline is rejected by the Joint Review Panel or stopped by other means, that the bitumen from Alberta should be carried by rail to Prince Rupert.

A pipeline to Prince Rupert has already been rejected by Enbridge as impractical given the mountainous terrain and the narrow footprint along the Skeena River from Terrace to Prince Rupert.

That means taking bitumen by rail to Prince Rupert has not been seriously studied—until now.

The State Department Environmental Impact Study (EIS) on the controversial Keystone XL pipeline from Alberta to the US Gulf, does give serious consideration to the rail to Rupert option.

That’s because under its mandate the State Department had to consider alternatives to Keystone. The detailed look at carrying crude to the west coast is contained in the “No Action Alternatives” section of the Keystone report (that is telling President Barack Obama what might happen if he takes no action on Keystone)

The EIS took a brief look at the possibilities of rail to Kitmat, but concentrates mostly on Prince Rupert.

As for sending bitumen to the Gulf,via rail and tanker, the Keystone report concludes, as have most analysts that even if bitumen was shipped by rail to Prince Rupert, it would be cheaper to send it to markets in Asia than through the Panama Canal to the US Gulf Coast.

If pipelines to the Canadian West coast are not expanded or approved, even incurring the additional cost of rail transport to the West Coast ports (Vancouver, Kitimat, or Prince Rupert), estimated at $6 per barrel, results in a total transport cost to Asia that is still 40 percent cheaper than going via the Gulf Coast.

Absent a complete block on crude oil exports from the Canadian West Coast, there would belittle economic incentive to use the proposed project as a pass through. The high costs of onward transport to other potential destinations tend to mitigate against WCSB [Western Canada Sedimentary Basin] heavy/oil sands crudes being exported in volume from the Gulf Coast.

As an alternative to Keystone, the State Department examined a scenario where bitumen and possibly Bakken shale crude oil would be:

• Loaded onto rail in Lloydminster and transported to Prince Rupert, British Columbia;

• Transferred to a new/expanded marine terminal at Prince Rupert; and

• Shipped via Suezmax vessels to the Gulf Coast area (Houston/Port Arthur) through the Panama Canal.

If the tanker cars are hauling bitumen, they would be actually loading “railbit” which the report says is “similar to dilbit but with less diluent added” (Dilbit is the standard diluted bitumen in pipelines) There is also, according to the EIS, a possibility that the tank cars would carry raw bitumen without dilutent (although this requires insulated rail cars with steam coils)

New facilities in Prince Rupert would consist of a large rail terminal complex, most likely on themainland, where off-loaded crude oil would be stored until it could be loaded onto tankers, and an expanded port. The entire facility would cover 4,700 acres (1,900 hectares), including 3,500 acres (1,400 hectares) for storage and off-loading/on-loading facilities at the rail terminal and approximately 1,200 acres (487 hectares) of land at the expanded port.

The new tank terminal construction would consist of the following:

• Fourteen petroleum storage tanks (11 oil and three condensate);

• A security fence to encompass the tank terminal;

• A 180-foot-wide (55 metre) firebreak area around the outside perimeter of the terminal;

• Electrical supply and distribution (this terminal would be serviced by the Texada Island

Reactor substation); and

• Buildings (control center and civil infrastructure including roads).

Related Link Prince Rupert Port Authority Performance Report

 

The scenario calls for adding approximately 13 trains with 100 tanker cars per day on the 1,100 miles (1,770 kilometres) of CN and Canadian Pacific rail lines between Lloydminster and Prince Rupert.

(On the other hand, media mogul David Black who has proposed a refinery at Onion Flats half way between Kitimat and Terrace is considering a rail link to Kitimat if the Northern Gateway pipeline is stopped. Black estimates there would be six trains per day, 120 cars in each direction. While there is usually only one train a day to Kitimat or less, that idea would increase traffic along the Skeena and in his news release Black says 

If BC remains set against a pipeline the oil will come to the refinery by rail. CN and the oil companies are keen on this. A great deal of crude in North America is being moved by rail now. The costs are not that different in this case and no permits are required. Rail tankering is, however, not as safe and it is more disruptive. Small towns along the route with level crossings would rue having 12 more trains running through every day.

The State Department scenario says that if the Prince Rupert option actually happened there would be “one to two additional Suezmax tanker vessels per day (430 tankers per year) would travel between Prince Rupert and the Gulf Coast area refinery ports via the Panama Canal.”

The concept of the Suezmax tankers is critical to the west coast, even if none of the scenarios eventually happen, because the State Department report notes that the Panama Canal is now being expanded, so that larger ships, including tankers, can go through the canal after 2014.

The current size is Panamax (maximum size for the current Panama Canal) to Suezmax (the maximum size for the Suez Canal), and, according to the State Department that means even if the even bigger Very Large Crude Carriers are not calling at west coast ports, the newer, larger Suezmax tankers may  be.

It should be noted, however, that if WCSB crude oil reaches a Pacific port, regardless of whether by rail or by pipeline, the economics for movement via tanker would favor shipping the oil to Asia rather than the Gulf Coast area. The cost of transporting crude oil via tanker from Prince Rupert to Houston and Port Arthur is estimated to be approximately $4.70/bbl, whereas the transport cost via tanker from Prince Rupert to refinery ports in Asia (e.g., Ulsan, South Korea and Dalian, China), is estimated to be only approximately $1.70 and $2.00/bbl, respectively. The lower transport cost to Asia versus the Gulf Coast area is attributable to shorter trip duration (30 to 37 days to Asia versus about 45 days to the Gulf Coast area), avoiding the Panama Canal toll(about $0.70/bbl), and being able to use a larger tanker because it would not be constrained by the Panama Canal (a VLCC tanker to China would have a capacity of almost 2 million bbl versus a Suezmax tanker to the Gulf Coast area with a capacity of about 884,000 bbl).

So what would happen if there was a scheme to truck bitumen and crude to Prince Rupert and ship via the Panama Canal to the Gulf?

The State Department EIS says:

 the transport of the crude oil via tankers from Prince Rupert to the Gulf Coast area refineries would not have any effects on geology, soils, groundwater, wetlands, vegetation, land use, socioeconomics, noise, or cultural resources, other than in the event of a spill.

It goes on to note:

The Gulf Coast area refineries already receive crude oil shipments via tankers from Mexico, Venezuela, and other locations; the Rail/Tanker Scenario is expected to simply displace these sources of crude oil with WCSB crude oil. Therefore, no new construction or new operational impacts are expected to occur as a result of this scenario at the Gulf Coast area refineries or surrounding habitats or communities.

In its study of a possible expanded Prince Rupert terminal that would welcome tankers, the State Department says:

The proposed Northern Gateway terminal at Kitimat, British Columbia was used as a surrogateto estimate the marine facilities needed at Prince Rupert. The Northern Gateway facility isdesigned to handle about 525,000 bpd of crude delivered by pipeline for loading on vessels to theWest Coast and Asia. In addition, it is designed to receive about 193,000 bpd of diluent (a verylight oil obtained from natural gas production) from cargoes arriving by water and discharging into storage at the terminal and moving back to Alberta via a parallel pipeline. The total volumeof about 718,000 bpd approximates the volume of WCSB heavy crude oil that would be loaded at Prince Rupert.

PART FOUR: State Department assessment of the railway to Rupert route for bitumen

Here are edited portions of the EIS assessment for a major oil terminal at Prince Rupert

Environmental Setting

The EIS says “the local surface geology at the Prince Rupert site consists of bedrock (granitic rocks) overlain by glacial outwash and a thin soil cover.” and goes on to note that “Prince Rupert is located along the coastal region of Canada, which is seismically active.”

Potential Impacts

At Prince Rupert, depth to bedrock is expected to be relatively shallow, so rock ripping and some blasting could be necessary. The impacts of rock ripping and blasting are limited to the immediate area and would not result in any significant impacts to the underlying or nearby geology. Excavation activities, erosion of fossil beds exposed due to grading, and unauthorized collection can damage or destroy paleontological resources during construction.

(The report notes that The potential for finding paleontological resources in the areas that would be disturbed is unknown. But the area of the coast has been heavily metamorphisized and most fossils, so far, have been found further inland, largely along the Copper River near Terrace)

In terms of geologic hazards, the Prince Rupert terminals would be located along the coastal region of Canada, which is seismically active. In addition, the presence of steep slopes increases the risk of landslides and the port’s coastal location increases the risk of flooding…. The Prince Rupert rail terminals and port facilities would be designed to withstand potential seismic hazards and flooding…

Construction of the proposed terminals and port expansion in Prince Rupert would result in the disturbance of approximately 3,500 acres (1,400 hectares) of land for the construction of the rail terminal complex and approximately 1,200 acres (487 hectares) for the expansion of the port. Potential impacts to the soils resources of the area could result from vegetation clearance, landscape grading, and recontouring to ensure proper drainage, the installation of storm water drainage systems, construction of the required infrastructure, and other construction activities.
One of the primary concerns during construction activities is soil erosion and sedimentation.
Potential impacts to soils from erosion are expected to occur in areas where the slopes are greater than 20 per cent and where the erosion potential due to their nature is high. Based on available landscape and soils information, the soils found in the area are not highly erodible and the required infrastructure would be located in areas that are relatively flat. Therefore, the impact of the proposed terminal complex and port construction activities on soil erosion would be minor.

 

Groundwater
Environmental Setting

The Prince Rupert Terminals and port expansion would occur in British Columbia on Kaien Island, which receives about 102 inches of rainfall per year. The terminals would be located on an inlet that is part of the eastern Pacific Ocean on the Venn Passage near the much larger Inland Passage, which extends from Washington State to Alaska along the islands and mainland of British Columbia, Canada. Venn and Inland Passages are marine (salt water) waterbodies. The islands consist of bedrock (granitic rocks) overlain by glacial outwash and a thin soil cover.
Groundwater is shallow, poor quality, and unused. Drinking water is derived from lakes on the mainland. Water quality in the terminal complex area is seawater and inland brackish.

Potential Impacts

During construction of the facilities at Prince Rupert, the primary potential impacts to groundwater would be spills or leaks from construction equipment. Mitigation for these impacts includes having in place appropriate plans in place and appropriate cleanup materials available.
During operations of the facilities at Prince Rupert, the primary potential impacts to groundwater would again most likely be spills or leaks from operation equipment or associated with crude oil unloading of railcars. Although the initial impacts of potential releases or spills may be contained or limited to soil, potential impacts to groundwater may occur depending on the depth to groundwater, soil characteristics (e.g., porosity, permeability), spill volume and extent, and whether the spill reaches surface water bodies, some of which are interconnected to groundwater.

Surface Water
Environmental Setting

The upland character surrounding the potential Prince Rupert terminal area is dominated by bog forest uplands and the flowing surface water bodies are predominantly precipitation- and shallow groundwater-fed intermittent streams. Some open waterbodies are present in the southeast portion of Kaien Island. Tidal shore zones are of a rugged and rocky nature and receive wave energy generated by naturally occurring fetch and large wakes from marine traffic. Winter winds are strong and from the southeast to southwest, with surface currents predominantly northward from the Hecate Strait. Lighter summer winds have less influence on currents and allow freshwater runoff from land and deep water tidal effects to exert more control and provide variation in summer current patterns. Significant wind and tidal mixing tend to occur where waters are shallow and around islands and rocky points of land. The coastal landscape is predominantly fjords carved into the granitic Coast Mountains, created by the last of several glacial periods approximately 12,000 years ago. Shores tend to be rocky and steep with beaches restricted to sheltered areas adjacent to estuaries and the navigable straits and channels provide a wide variety of exposures and habitats.

Potential Impacts

Construction of the facilities at Prince Rupert would disturb approximately 4,700 acres. The primary potential impacts to surface waters include erosion and sedimentation and spills/leaks of hazardous materials. Mitigation for these impacts includes having in place appropriate SPCC plans in place and appropriate cleanup materials available.
During operations, the primary potential impacts to surface waters include storm water runoff, spills, or leaks from operation equipment or associated with crude oil unloading of railcars.
Provision of storm water management measures would mitigate the impacts of stormwater runoff.

Terrestrial Vegetation
Environmental Setting

The Prince Rupert terminals and port facilities would be located in the Coastal Gap Level III Ecoregion. The vegetation immediately adjacent to the Pacific Ocean includes stunted, opengrowing western red cedar, yellow cedar, and western hemlock with some stunted shore pine and Sitka spruce . There are also open areas present within the affected areas. It is unclear if biologically unique landscapes or vegetation communities of concern exist within the proposed Prince Rupert terminal complex boundary.

Potential Impacts

The proposed rail terminal complex and port facilities at Prince Rupert would require the clearing of up to 4,700 acres of natural vegetation, most of which is forested based on aerial photo interpretation. There does not appear to be any biologically unique landscapes or communities of conservation concern within the terminal complex boundary. Nearly all of these impacts would be permanent as natural habitats are converted for use as rail terminals and port facilities.

Wildlife
Environmental Setting

Many wildlife species use this coastal area for hunting, foraging, roosting, breeding, and nesting (Tourism Prince Rupert 2012). Wildlife characteristic of this ecoregion include grizzly bear (Ursus arctos horribilis), black bear (Ursus americanus), mountain goat (Oreamnos americanus), black-tailed deer (Odocoileus hemionus
columbianus), wolf (Canis lupus), moose (Alces alces), mink (Mustela sp.), bald eagle
(Haliaeetus leucocephalus), seabirds, shorebirds, waterfowl, and grouse (Tetraoninae)
The Prince Rupert terminal complex would be located in the Northern Pacific Rainforest(Region 5) bird conservation region, which is an ecologically distinct region in North America…

The coast of the Northern Pacific Rainforest is characterized by river deltas
and pockets of estuarine and freshwater wetlands set within steep, rocky shorelines. These wetlands provide critical nesting, wintering, and migration habitat for internationally significant populations of waterfowl and other wetland-dependent species. The area includes major stopover sites for migrating shorebirds, especially western sandpipers (Calidris mauri) and dunlins (Calidris alpina). Black oystercatchers (Haematopus bachmani), rock sandpipers (Calidris
ptilocnemis), black turnstones (Arenaria melanocephala), and surfbirds (Aphriza virgata) are common wintering species. Nearshore marine areas support many nesting and wintering sea ducks. Many seabirds breed on offshore islands, including important populations of ancient murrelet (Synthliboramphus antiquus), rhinoceros auklet (Cerorhinca monocerata), tufted puffin (Fratercula cirrhata), common murre (Uria aalge), western gull (Larus occidentalis), glaucouswinged gull (Larus glaucescens), and Leach’s storm-petrel (Oceanodroma leucorhoa). Pelagic
waters provide habitat for large numbers of shearwaters (Calonectris spp. and Puffinus spp.), storm-petrels (Hydrobatidae), and black-footed albatross (Phoebastria nigripes)

Potential Impacts

Direct impacts could occur due to vegetation removal or conversion, obstructions to movement patterns, or the removal of native habitats that may be used for foraging, nesting, roosting, or other wildlife uses (Barber et al. 2010). Indirect impacts to wildlife are difficult to quantify and are dependent on the sensitivity of the species, individual, type and timing of activity, physical parameters (e.g., cover, climate, and topography), and seasonal use patterns of the species (Berger 2004). Most of these impacts would be essentially permanent.

Fisheries
Environmental Setting

Prince Rupert is an important deepwater port and transportation hub of the northern coast of British Columbia. It is located on the northwest shore of Kaien Island, which is connected to the mainland by a short bridge. The town of Prince Rupert is just north of the mouth of the Skeena River, a major salmon-producing river. Key commercial fisheries include Pacific salmon, halibut, herring, and groundfish, which are processed from Prince Rupert.

Prince Rupert area supports a high density of streams and rivers that host an array of valuable recreational fisheries for salmon, steelhead (anadromous rainbow trout), rainbow trout, lake trout, cutthroat trout, char, Arctic grayling, and northern pike .

Potential Impacts

New impacts to commercial and recreational fisheries’ habitats from the construction and operation of the facilities in Prince Rupert could include marine intertidal zones as well as fish spawning zones (e.g., herring), if present. There would likely be short-term impacts to the benthic (bottom dwelling) community during construction of the berths and mooring facilities. Bottom-dwelling
fish (i.e., halibut, flounder, and rockfish) and marine invertebrates (i.e., clams, mussels, crabs, and other bivalves and crustaceans) could potentially be impacted during construction as well, but these affects are expected to be minor and temporary or short-term in duration.

Additional shipping traffic would increase underwater sound because large vessels, including tankers, put out relatively high noise levels. Fish and other aquatic organisms (including invertebrates and marine mammals) use sound as a means of communication and detection within the marine acoustic environment. Increased shipping traffic could mask natural sounds by increasing the ambient noise environment from Prince Rupert Harbor and along the marine route to the Gulf Coast area. Long-lasting sounds, such as those caused by continuous ship operation, can cause a general increase in background noise and there is a risk that such sounds, while not causing immediate injury, could mask biologically important sounds, cause hearing loss in affected organisms, and/or have an impact on stress levels and on the immune systems of aquatic species.

Exotic and invasive species are sometimes transferred in the ballast water of tanker ships.
Monitoring and controls would need to be implemented to treat ballast water discharged into Prince Rupert Harbor such that invasive or exotic species would not be released into the marine environment.

Threatened and Endangered Species

This section focuses on animal and plant species present in the Prince Rupert area that are Canada SARA protected. As a coastal area along the Pacific Migratory Bird Route, and an area that receives a lot of precipitation and is heavily forested, many wildlife species inhabit the area, as discussed in Section 5.1.3.6, Wildlife. According to the British Columbia (B.C.) Conservation Data Centre (2012), only one SARA threatened/endangered species is known to occur in Prince Rupert—the green sturgeon (Acipenser medirostris), a Pacific Ocean inhabitant. In addition, several SARA special concern species occur in Prince Rupert, including western toad (Anaxyrus boreas), coastal tailed frog (Ascaphus truei), North American racer (Coluber constrictor), grey whale (Eschrichtius robustus), and Stellar sea lion (Eumetopias jubatus)

Potential Impacts

The green sturgeon is typically found along nearshore marine waters, but is also commonly observed in bays and estuaries. The expansion of the proposed port facility could have minor adverse effects on the green sturgeon, but the sturgeon could readily avoid the port area.
Increased shipping traffic at Prince Rupert and as the vessels transit to the Gulf Coast area refineries may affect the feeding success of marine mammals (including threatened and endangered species) through disturbance, because the noise generated by tankers could reduce the effectiveness of echolocation used by marine mammals to forage for food. Whales use underwater vocalizations to communicate between individuals while hunting and while engaged in other behaviors. Increased underwater noise from additional shipping traffic could disrupt these vocalizations and alter the behavior of pods of whales. Moreover, additional boat and
tanker traffic could also increase the potential for collisions between marine mammals and shipping vessels. These effects would be additive in nature and could potentially add to existing disturbance effects and collision risks caused by the current level of shipping traffic, commercial and recreational fishing, and cruise ship passage.

Land Use, Recreation, and Visual Resources
Environmental Setting

Land use, recreation, and visual resources for the Prince Rupert area where the new terminals and expanded port facilities would be built differ sharply from the other terminal sites. Prince Rupert is located on an inlet of the Pacific Ocean in a heavily forested area of British Columbia.
Urban land use is generally limited to the communities in and around the city of Prince Rupert, with some small outlying communities and villages in the area. Given Prince Rupert’s role as a terminus of the Alaska Ferry System, many people see the port and surrounding areas in a recreational context. The area is largely undeveloped and would be sensitive to changes in the visual landscape.

Potential Impacts

If constructed on previously undeveloped land, the new facilities would primarily impact mixed forest… The construction and operational impacts on land use, recreation, and visual resources at the Lloydminster, Epping, and Stroud terminal complex sites and along the Cushing pipeline route would be the same as for the Rail/Pipeline Scenario.

Socioeconomics
Environmental Setting

Population/Housing

Construction and operations activities are not expected to have a significant effect on population and housing for this scenario. Because construction and operations job estimates have not yet been determined for this scenario, worker requirements for Prince Rupert, Lloydminster, and Epping are assumed to be minor..additional temporary housing could be needed in Prince Rupert… Prince Rupert only has about 740 hotel/motel rooms

Local Economic Activity

Tanker infrastructure and operations would be affected as ships transport crude oil from Prince Rupert through the Panama Canal to Texas ports near Houston.

Direct construction expenditures for facilities at Prince Rupert would be approximately $700 million, with approximately 1,400 annual construction jobs, based on the cost estimates of the proposed Enbridge Northern Gateway marine terminal in Kitimat

Despite the large population of First Nations people in the Prince Rupert area, Canada does not have a similar definition to minorities as the Keystone report applied under US law and so it notes “Impacts to minority and low-income populations during construction and would be similar to those described for the proposed [Keystone] Project and could possibly result in increased competition for medical or health services in underserved populations. Canada does not define HPSA and MUA/P, so it is unknown whether or not the minority populations in Prince Rupert or Lloydminster exist in a medically underserved area.

Tax Revenues and Property Values

It says construction of a new terminal Prince Rupert would generate provincial sales taxes, goods and services taxes, and hotel taxes. Construction of the tank and marine terminals at Prince Rupert…would involve large numbers of road trips by heavy trucks to transport construction materials and equipment to and from the sites. Construction in Prince Rupert could also potentially involve vessel deliveries of material. This traffic could cause congestion on major roadways, and would likely require temporary traffic management solutions such as police escorts for oversize vehicles.

Cultural Resources

Despite the rich heritage of First Nations in the Prince Rupert area, the Keystone alternative study reported;

No cultural resources studies have been conducted for the Prince Rupert area. Review of aerial photographs shows that a small portion of the area that could potentially be developed has already been disturbed by development, including port facilities, structures, and roads. This preliminary review shows that most of the area appears undeveloped and would have the potential for intact buried cultural resources.

The report notes that “Any ground disturbance, especially of previously undisturbed ground, could potentially directly impact cultural resources.”

It goes on to note that the potential to

include intact buried cultural resources would require evaluation through research and cultural resources surveys. If cultural resources were identified, follow-up studies could be required. In general terms, the archaeological potential of heavily disturbed areas, such as might be found in active rail yards or within developed transportation corridors, is normally lower than in undisturbed areas.

Archaeological potential is also contingent upon factors such as access to water, soil type, and topography, and would have to be evaluated for each area to be disturbed. Aboveground facilities have the potential to indirectly impact cultural resources from which they may be visible or audible. The potential for increased rail traffic to contribute to indirect impacts would require consideration.

Air and Noise

The report also summarizes the possible green house gas emissions for the rail and tanker project as whole from Prince Rupert to the Gulf Coast refineres and notes that overall

On an aggregate basis, criteria pollutant emissions, direct and indirect GHG emissions, and noise levels during the operation phase for this scenario would be significantly higher than that of the proposed [Keystone XL] Project mainly due to the increased regular operation of railcars, tankers, and new rail and marine terminals.

Air Quality

The rail cars and tankers transporting the crudes would consume large amounts of diesel fuel and fuel oil each day….The criteria pollutant emissions would
vary by transportation segment, particularly during marine-based transit. Oil tankers traveling from the Prince Rupert marine terminal through the Panama Canal to Houston/Port Arthur pass through several different operational zones, including reduced speed zones leading into and out of the ports, North American Emission Control Areas where the use of low-sulfur marine fuel is mandated, and offshore areas where the tankers travel at cruise speeds.

During the return trip, tankers are filled with seawater (ballast) to achieve buoyancy necessary for proper operation, which affects the transit speeds of the vessel. Furthermore, the tankers spend several days loading or unloading cargo at each marine terminal with auxiliary engines running (an activity called hoteling). The tanker emissions accounted for return trips (i.e., both loaded cargo going south and unloaded cargo going north).

In aggregate, the total operational emissions (tons) estimated over the life of the project (50 years) are several times greater than those associated with the combined construction and operation of the proposed Keyston XL Project

Greenhouse Gases

Direct emissions of GHGs would occur during the construction and operation of the Rail/Tanker Scenario. GHGs would be emitted during the construction phase from several sources or activities, such as clearing and open burning of vegetation during site preparation, operation of on-road vehicles transporting construction materials, and operation of construction equipment for the new pipeline, rail segments, multiple rail and marine terminals, and fuel storage tanks.

Due to limited activity data, GHG emissions from construction of the Rail/Tanker Scenario were not quantified; however, these emissions would occur over a short-term and temporary period, so construction GHG impacts are expected to be comparable to the proposed [Keystone XL] Project.
During operation of the railcars and tankers that comprise this scenario, GHGs would be emitted directly from the combustion of diesel fuel in railcars traveling over 4,800 miles (7,725 km) and fuel oil in marine tankers traveling over 13,600 miles (21,887 km) round-trip.

The Rail/Tanker Scenario would also result in indirect emissions of GHGs due to the operation of 16 new rail terminals, an expanded port, and potential pumping stations. The new rail terminal in Prince Rupert would be projected to require 5 MW of electric power to operate, possibly bring indirect GHG emissions

Noise

Noise would be generated during the construction and operation of the Rail/Tanker Scenario. Noise would be generated during the construction phase from the use of heavy construction equipment and vehicles for the new pipeline, rail segments, and multiple rail and marine terminals, and fuel storage tanks. Due to limited activity/design data, noise levels from the construction of this scenario were not quantified; however, this noise would occur over a short term and temporary period, so construction noise impacts are expected to be comparable to those
of the proposed Project. During operation of the railcars and tanker ships that comprise this scenario, noise would be generated from the locomotives, movement of freight cars and wheels making contact with the rails as the train passes, train horns, warning bells (crossing signals) at street crossings, and tanker engines during hoteling and maneuverings at the new rail and marine terminals in Prince Rupert.

(Noise from ocean going vessels which is a concern for coastal First Nations and environmental groups is covered later on impact on wildlife)

 

Climate Change Effects on the Scenario
Environmental Setting

The Keystone study looks at the affects of climate change, but concentrates largely on the Gulf Coast beause the most of the Rail/Tanker Scenario was outside of the boundaries of the study, but it does note that the sea levels are projected to rise due to glacial melting and thermal expansion of the water. The rate, total increase, and likelihood of the rise is in part dependent on how rapid the ice sheets warm and is a source of ongoing scientific uncertainty.

The United States Global Change Research Program (USGCRP) estimates that sea level rise could be between 3 to 4 feet by the end of the century.

Increasing sea level projected due to climate changes as described above shifts the impact of mean high tide, storm surge, and saltwater intrusion to occur further inland and this would negatively affect reliable operation of the port infrastrucure for tanker traffic. Mitigation of these climate effects could be addressed by making engineering and operational changes at the port.

Potential Risk and Safety
Environmental Setting

The Rail/Tanker Option would combine the risk inherent in both pipeline and oil tanker
transport. However, the risks and consequences for using oil tankers to transport the hazardous materials are potentially greater than the proposed Project. Overall, crude oil transportation via oil tankers has historically had a higher safety incident rate than pipelines for fire/explosion, injuries, and deaths.

Spills have been reported while the vessel is loading, unloading, bunkering, or engaged in other operations

The main causes of oil tanker spills are the following:
• Collisions: impact of the vessel with objects at sea, including other vessels (allision);
• Equipment failure: vessel system component fault or malfunction that originated the release of crude oil;
• Fires and explosions: combustion of the flammable cargo transported onboard;
• Groundings: running ashore of the vessel; and
• Hull failures: loss of mechanical integrity of the external shell of the vessel.

From 1970 to 2011, historical data shows that collisions and groundings were the maincauses of oil tanker spills worldwide.

Potential Impacts

Loading and unloading of the railcars at tank farms near seaports could allow spills to migrate and impact seawaters and shorelines.

However, the loading and unloading are generally carried out under supervision and would be addressed promptly by the operators, limiting the potential migration and impacts of the spill to the immediate area.

Once the tanker is loaded and at sea, the propagation and impacts of a spill could become significant. Oil tankers may carry up to 2,000,000 bbl of oil

A release of oil at sea would be influenced by wind, waves, and current. Depending on the volume of the release, the spreading of oil on the surface could impact many square miles of ocean and oil birds, fish, whales, and other mammals and could eventually impact shorelines. Oil would also mix with particulates in sea water and degrade. As this occurs some oil will begin to sink and either be retained in the water column (pelagic) or settle to the ocean floor (sessile).

Pelagic oil could be consumed by fish or oil fauna passing though the submerged oil. Sessile oil could mix with bottom sediment and potentially consumed by bottom feeding fauna. Spills in ports-of-call could affect receptors similar to an open ocean release but also could temporarily affect vessel traffic and close ports for cleanup activities.

The identification of key receptors along the rail route alternative was not available for this evaluation. Therefore a comparison to the proposed project was not completed.

Surface Water

The Lloydminster to Prince Rupert portion of this route would begin in the western plains at the Saskatchewan/British Columbia border and travel west through an area of high-relief mountains with large valleys, referred to as the Cordillera region. From a water resource perspective, the plains region of Canada is characterized by relatively large rivers with low gradients. The plains rivers drain the Rocky Mountains to the Arctic Ocean. The Cordillera region is largely composed of northwest-southwest trending mountain ranges that intercept large volumes of Pacific
moisture traveling from the west towards the east. River systems in this region are supplied by a combination of seasonal rainfall, permanent snowfields, and glaciers.

The following are larger rivers crossed by the existing rail lines between Lloydminster and Prince Rupert:

• North Saskatchewan River, Alberta
• Pembina River, Alberta
• McLeod River, Alberta
• Fraser River, British Columbia
• Nechako River, British Columbia
• Skeena River, British Columbia

Wetlands

Spills within wetlands would most likely be localized, unless they were to occur in open, flowing water conditions such as a river or in the ocean. A crude oil spill in a wetland could affect vegetation, soils, and hydrology. The magnitude of impact would depend on numerous factors including but not limited to the volume of spill, location of spill, wetland type (i.e., tidal versus wet meadow wetland), time of year, and spill response effectiveness. The construction of additional passing lanes to accommodate increased train traffic resulting from this scenario could
result in permanent impacts to wetlands if passing lanes were constructed where wetlands occur.
However, as there is some leeway regarding the exact location of the passing lanes, it is expected that wetlands would be avoided by design.

Fisheries

The Rail/Tanker Scenario railroad route would cross numerous major streams and rivers in Canada, many of which support anadromous fish species such as salmon.

Anadromous species are those that spawn and rear in freshwater but migrate to the ocean at a certain size and age. Pacific salmon are large anadromous fish that support valuable commercial and recreational fisheries. Commercial fisheries for salmon occur in marine water and most recreational fishing for salmon occurs in freshwater. Salmon eggs are vulnerable to the effects of fine sediment deposition because female salmon deposit their eggs in stream bed gravels.

Despite this vulnerability, the overland railway route is not expected to present any new impacts to salmon unless there is a spill into its habitat, although the risk of spills does increase under this scenario due to the increase in the number of trains that would use the route.

Potential new impacts under the Rail/Tanker Scenario on commercially or recreationally significant fisheries along the route would be minor because the railroads that would be used are already built and in operation. However, the risk of an oil spill or release of oil or other materials still exists. The tanker portion of this route scenario is also subject to oil spill risk.

Threatened and Endangered Species

The rail route would cross over the Rocky Mountain region of western Alberta, which is inhabited by species such as the woodland caribou (Rangifer tarandus) (a SARA threatened species) and grizzly bear (a SARA special concern species). This region of British Columbia is home to a number of SARA threatened/endangered species, including the peregrine falcon (Falco peregrinus anatum) (SARA threatened), salish sucker (Catostomus sp.) (SARA endangered), white sturgeon (Acipenser transmontanus) (SARA endangered), caribou (southern mountain population) (SARA threatened), northern goshawk (Accipiter gentilis laingi) (SARA threatened), and Haller’s apple moss (Bartramia halleriana) (SARA threatened).

A number of additional SARA special concern species inhabit the regions of Canada that would be traversed by the Rail/Tanker Scenario, including but not limited to those special concern species expected to occur in the Prince Rupert region, and discussed above (B.C. Conservation Centre 2012).

Two days left for public input on BC “heavy oil” spill response plans

oilspillresonsepaperResidents of British Columbia have just two days to file information and opinions on the province’s  plans for “options for strengthening BC’s spill preparedness and response policies and capacity.”

A page on the BC Ministry of the Environment’s web site  wants public input as part of “BC’s five conditions necessary for support of heavy oil projects.”

Premier Christy Clark announced her controversial five conditions for pipeline development in BC in July 2012. Clark’s announcement was aimed both at the Northern Gateway Pipeline which would have its terminal in Kitimat, and the proposed Kinder Morgan pipeline expansion which has its terminal in Vancouver.

It is not clear how long the web page has been up,  but the call for input from the public has received little, if any, publicity. The deadline for public submissions is February 15, 2013.

(Northwest Coast Energy News was alerted to the story by a Kitimat-based hiking club)

A separate call for academic papers had a deadline of January 25. The province plans a conference on oil spill response  in Vancouver from March 25 to March 27. The website says”

As part of British Columbia’s commitment to a world leading preparedness and response regime for land based spills, it is hosting a symposium March 25-27, 2013 in Vancouver, BC. Due to the anticipated high interest in the symposium, attendance is by invitation only.

One question would be if invitation only is designed to exclude activist groups who may wish to participate or demonstrate. The Northern Gateway Joint Review panel banned public input at hearings in Vancouver and Victoria earlier this year to try, not always successfully, to head off demonstrations. The webpage says:

In keeping with the established polluter-pay principle, and recognizing the increase in development activities across the province, the Ministry of Environment (the ministry) is reviewing industry funded options for strengthening BC’s spill preparedness and response policies and capacity. Land based spill refers to any spill impacting the terrestrial environment, including coastal shorelines, regardless of the source.

This review addresses three aspects of land based spill preparedness and response: World leading regime for land based spill preparedness and response

Effective and efficient rules for restoration of the environment following a spill

Effective government oversight and coordination of industry spill response The ministry has developed a policy intentions paper for consultation (intentions paper) on the three aspects of the province’s land based spill preparedness and response regime under consideration.

The purpose of this intentions paper is to describe the ministry’s proposed policy direction and seek input on enhancing spill preparedness and response in BC. The intentions paper is a discussion document and your feedback will influence the policy approach.

Although the call for input is on the ministry website, the contact is a management consulting firm C. Rankin & Associates.

Expansion of proposed Kitimat bitumen terminal urgent to get offshore markets, Enbridge tells JRP

Enbridge Northern Gateway has told the Joint Review Panel that expansion of the proposed bitumen and condensate terminal in Kitimat is urgent so the company can access offshore markets for Alberta bitumen sands crude.

Northern Gateway filed an update on its plans for the Kitimat in response to a ruling from the JRP, after Smithers-based activist Josette Weir questioned how Enbridge filed a route update with the panel which included the plans to expand the terminal.

The JRP ruled against two of Weir’s motions but upheld, in part, her objection that the terminal plans were not part of a route revision.

In the Motion, Ms. Wier argues that there are a number of completely unrelated documents embedded within the route revision changes including, for example, a “noticeable increase in the number of oil tanks at the Kitimat terminal” with “significant size increases included.” There is no discussion in the update documents on how these changes are related to the proposed routing change. Ms. Wier further notes that this evidence was submitted after the completion of questioning on engineering (including regarding the Kitimat tank farm) in Prince George last
November.

The Panel notes that it may be of use to parties for Northern Gateway to identify which of the exhibits submitted on 28 December, 2012, were: (i) directly related to Route Revision V; (ii)corollary to Route Revision V; or (iii) unrelated to Route Revision V. Accordingly, the Panelorders Northern Gateway to submit, on or before 1 February 2013, a chart setting out this information for each of the exhibits submitted in the 28 December 2012 update. Further, where the documents are listed as “unrelated to Route Revision V”, Northern Gateway is to provide a
brief description as to why this evidence is being filed at this time.

 

In response, Northern Gateway filed a spreadsheet with the JRP to clarify the reasons for including the expansion of the tank farm. As the JRP requested, the explanation is brief, but significant.

Northern Gateway stated that “the size and spacing of tanks will be optimized during detailed design.”

In recognition of the urgency of accessing offshore markets, Northern Gateway and its Funding Participants have recently agreed to proceed with engineering and design activities.

Brief description as to why this evidence is being filed at this time required:

…for preparation of a Class III Cost Estimate, at an expected cost of over $150 million. Discussions with the Funding Participants in late 2012 resulted in a more detailed analysis of the tankage required by shippers, with particular emphasis on ensuring an adequate degree of commodity segregation within the tank farm. That analysis, which concluded in December 2012, revealed that additional tankage would be required to satisfy commodity segregation requirements.

Northern Gateway included this information along with its Route V filing as a matter of convenience to all involved.

In respone to Weir’s objection that the Enbridge Northern Gateway filed a major change to the project and noted that most intervenors are limited to the deadlines set by the JRP, and that the engineering hearings in Prince George had already concluded.

In response, the panel ruled that Enbridge could present the evidence at the marine hearings in Prince Rupert that resumed today.

In its letter enclosing the 28 December 2012 update on Route Revision V, Northern Gateway noted that, “to the extent that there are questions regarding this filing that have not been previously addressed, members of the Northern Gateway Kitimat River Valley engineering design and emergency preparedness witness panel will be available to answer same when they appear in Prince Rupert.”

The Panel is of the view that any substantive questions on the updated evidence could best be
addressed through questioning in Prince Rupert, as suggested.

At the opening of the hearings in Prince Rupert, Coastal First Nations withdrew from the process, citing the cost and complexity of the hearings. Both events once again call into question the fairness of the Joint Review Process and whether or not there is a double standard, with one set of standards for Enbridge Northern Gateway and another for intervenors.

Intervenor files challenge after Enbridge tells JRP it wants major expansion of Kitimat Gateway terminal

Revised Enbridge map of Kitimat harbour.
Enbridge filed a revised map of Kitimat harbour with the revised route for the Northern Gateway Pipeline and terminal in December 2012.

Enbridge Northern Gateway wants a much larger tank farm at its proposed Kitimat terminal, the company says in documents filed with the Joint Review Panel on December 28, 2012.

On that date, Enbridge filed its fifth revision of the Northern Gateway pipeline route and plans with the JRP. While for Enbridge engineers the filing may be a routine update, as surveys and planning continue, Smithers based enviromentalist Josette Weir has filed an objection with the JRP challenging the revised plans because, she says, the JRP has closed off any opportunity for intenvenors to make their own updates, calling into question once again the fairness of the JRP process.

From the documents filed with the JRP, it appears that Enbridge wants not only to expand the tank farm and adjacent areas but also to have a potentially much larger area on the shores of Douglas Channel for even more expansion in the future.

At the Kitimat terminal, Enbridge says there will now be 16 oil tanks, up from the original 11. The company also says: “The terminal site will also have some limited additional civil site development to allow for potential future site utilization.” While Enbridge proposes to keep the number of condensate tanks at three, their capacity would be increased.

In addition, Enbridge wants an enlarged “remote impoundment reservoir” to comply with the BC Fire Code, so that it would be:

• 100% of the volume of the largest tank in the tank farm, plus
• 10% of the aggregate volume of the 18 remaining tanks, plus
• an allowance for potential future tanks, plus
• 100% of the runoff from the catchment area for a 1 in 100 year, 24 hour storm event, plus
• the amount of fire water generated from potential firefighting activities at the tank farm.

Enbridge goes on to note:

An update to 16 oil tanks at the Kitimat Terminal is not expected to alter overall visibility of the marine terminal and therefore impact visual or aesthetic resources.

In her news release, Josette Wier, who describes herself as “an independent not funded intervenor in the hearing process,” says she filed a notice of motion on January 17, 2013, noting “there are numerous embedded proposed changes which have nothing to do with the route revision,” including the fact that “the tank farm in Kitimat is considerably increased from 11 to 16 tanks for the oil tanks with an almost doubled working capacity, while the condensate tanks capacity is increased by 29 per cent.”

“What does this have to do with a route revision?” she asks in the news release.

In the news release, Wier says: “that this is an abuse of process when engineering and design question period ended in Prince George last November.  Not withstanding the underhanded way of presenting new evidence, re-questioning on those issues doubles the amount of work and expenses for intervenors.

“Abuse of process”

She asked the Joint Review Panel to order Northern Gateway to re-submit their proposed changes indicating clearly the ones unrelated to the route changes and describing them along with their rationale.

Wier goes on to say: “It is everyone’s guess why there is a doubling of the tank farm capacity, but certainly points out to the larger pipeline shipping volumes the company had indicated would be a possible Phase II of the project.” She says: “It looks like Northern Gateway is quietly moving into the 850,000 barrels a day proposal, twice the volume the application has been cross-examined about.  It is clearly an abuse of process.”

In her actual notice of motion, Wier goes further by taking aim at the JRP itself by saying that “the Applicant [Enbridge] can make changes to the Application whenever they want. We have already seen in their July submissions inclusion of new evidence which conveniently escaped information requests. The added work and cost imposed on intervenors and the Panel seem irrelevant to the Applicant.” She complains that her requests for more information in an earlier notice of motion “was dismissed by the Panel on the grounds that my request ‘would require an unreasonable amount of effort (both by Northern Gateway and other parties reviewing the material’ …. If this argument applied to my Notice of Motion, I suggest it should apply to embedded changes buried in the Applicant’s filings of December 28, 2012.”

Rerouting at Burns Lake

A number of the other changes appear to show continued strained relations between Enbridge and First Nations, for example it says:

There is a possibility of relocating the pipeline route… further north of the Burns
Lake area to avoid proposed Indian Reserve lands that would overlap the pipeline route,.. This revision will be evaluated when further information on the proposed Indian Reserve lands is available and when further consultation with the relevant Aboriginal groups has taken place.

On the other hand the revisions also show that the pipeline will be now routed through an existing right of way through the Alexander First Nation, near Morinville, Alberta, as part of an agreement with the Alexander First Nation.

Another route change is near the Morice River, where Enbridge says

The Morice River Area alternate will generally have less effect on wildlife riparian habitat since it is located away from the Morice River and floodplain. This revision is also farther from the proposed Wildlife Habitat Area for the Telkwa caribou herd and no longer intersects any primary and secondary goat ungulate winter range polygons. However, this revision no longer parallels the Morice West Forestry Service Road (FSR) and Crystal Creek FSR and offers fewer opportunities to use existing rights-of-way. This may increase linkages between cutblock road networks and increase human access locally but does not preclude Northen Gateway from applying other methods to minimize linear feature density in this region.

Wier also complains that the Enbridge did not properly file its latest documents, asking the panel to rule that it order Northern Gateway to re-submit their last revisions submitted in December
using proper JRP evidence numbering system and “Adobe pages numbers.” The huge number of documents in the JRP system is confusing and improper filing makes it harder for intervenors and others to sort their way through new information.

Northern Gateway NEB Application Update Dec. 2012

New Joint Review Panel possible for Coastal GasLink pipeline project to Kitimat

The federal Environment Assessment Agency is asking northwestern British Columbia to comment on whether or not a federal assessment is needed for the TransCanada Coastal GasLink pipeline project that would feed natural gas to the proposed Shell facility in Kitimat.

In a news release from Ottawa, the CEAA said:

As part of the strengthened and modernized Canadian Environmental Assessment Act, 2012 (CEAA 2012) put in place to support the government’s responsible resource development initiative, the Canadian Environmental Assessment Agency must determine whether a federal environmental assessment is required pursuant to the CEAA 2012 for the proposed Coastal GasLink Pipeline Project in British Columbia (B.C.). To assist it in making its decision, the Agency is seeking comments from the public on the project and its potential effects on the environment.

Coastal GasLink Pipeline Ltd. is proposing the construction and operation of an approximately 650-km pipeline to deliver natural gas from the area near the community of Groundbirch, B.C. (40 km west of Dawson Creek) to a proposed liquefied natural gas facility near Kitimat, B.C. The project will initially have the capacity to flow approximately 1.7 billion cubic feet of natural gas per day and could deliver up to approximately 5.0 billion cubic feet per day of natural gas after further expansion.

Written comments must be submitted by December 3, 2012.

Like the current Enbridge Northern Gateway project Joint Review Panel and the National Energy Board hearings in June 2011 on the Kitimat LNG project all comments received will be considered public.

The CEAA says after it has received the comments whether or not there should be an assessmet, it will post a decision on its website stating whether a federal environmental assessment is required.

The CEAA goes on to say:

If it is determined that a federal environmental assessment is required, the public will have three more opportunities to comment on this project, consistent with the transparency and public engagement elements of CEAA 2012.

Projects subject to CEAA 2012 are assessed using a science-based approach. If the project is permitted to proceed to the next phase, it will continue to be subject to Canada’s strong environmental laws, rigorous enforcement and follow-up, and increased fines.

If there is a federal assessment, the most likely course would be to create a new Joint Review Panel. However, this will not be a JRP with the National Energy Board, because the Coastal GasLink project does not cross a provincial boundary, thus it would not make it subject to scrutiny by the NEB.

Instead, if current practice is followed (and that is uncertain given the evolving role of the Harper government in environmental decisions) the new JRP would be in partnership with the British Columbia Oil and Gas Commission, which has jurisdiction over energy projects that are entirely within the province of BC.

However. Shell will have to apply to the NEB for an export licence for the natural gas as both the KM LNG and BC LNG projects did last year. That could result in parallel hearings, one for the export licence, and a second on the environmental issues, which, of course, is the direct opposite of what the Harper government intended when it said it would speed up the reviews with its “one project, one review” policy.

 

Confusion at Alberta Jackpine JRP

At present, there is a  CAEE-Alberta Energy Resources Conservation Board Joint Review Process underway in northern Alberta for the controversial Shell Canada Jackpine project.  Shell has proposed expanding the Jackpine Mine about 70 kilometres north of Fort McMurray on the east side of the Athabasca River. The expansion project would increase bitumen production by 100,000 barrels per day, bringing production at the mine to 300,000 barrels per day.

The Jackpine Joint Review Panel is the first to held under the new rules from Bill C-38 that limit environmental assessment.

The lead up to the Alberta Jackpine Joint Review Panel hearings was mired in confusion, partly because of the restrictions imposed by the Harper government in Bill C-38 which limited the scope of environmental assessments.

The local Athabasca Chipewyan First Nation is opposed to the project and, in October, argued that it should be allowed to issue a legal challenge against Shell’s proposed expansion of the Jackpine project.

According to initial media reports in The Financial Post, the Joint Review Panel excluded First Nations further downstream from the Jackpine project ruling and individual members of the Athabasca Chipewyan First Nation that they were not “interested parties.” The Post cited rules on who can participate were tightened up when the Harper government changed the criterion for environmental assessment under Bill C-38. The Financial Post reported a French-owned oil company was permitted to participate.

On October 26, the Jackpine JRP ruled that it did not have the jurisdiction to consider questions of constitutional law, but told the Athabasca Chipewyan First Nation and the Alberta Metis that it would “consider the evidence and argument relating to the potential effects of the project brought forward by Aboriginal groups and individuals during the course of the hearing.”

A few days after the Financial Post report, Gary Perkins, counsel for the Jackpine Joint Review Panel released a letter to participants including Bill Erasmus, Dene National chief and Assembly of First Nations regional chief, who said he was denied standing. There appears to have been confusion over how people could register as intervenors for the Jackpine hearings, since according to the Perkins letter they apparently did so on a company website that no relation to the Jackpine JRP. Perkins also attempted to clarify its constitutional role with First Nations, saying it did not have jurisdiction to decide whether or not the Crown was consulting properly. (PDF copy below)

The Perkins letter also said that the Fort McKay First Nation, Fort McMurray First Nation #468, the Athabasca Cree First Nation, Fort McKay Metis Community Association and the Metis Association of Alberta Region 1 plus some individual members of First Nations are allowed to participate in the hearings.

Controversy continued as the hearings opened, as reported in Fort McMurray Today, that there was poor consultation between Shell and the local First Nations and Metis communities.

On November 8, ACFN spokesperson Eriel Deranger and Athabasca Chipewyan Chief Allan Adam said the project was a threat to the traditional life of Alberta First Nations: “Our land … have shrunk and continue to shrink because of the development,” Adam told the newspaper.

Hot potato for the District of Kitimat

The arcane rules of the Northern Gateway Joint Review Panel has caused months of confusion and frustration for many of those who participated, whether they from the BC provincial Department of Justice or other government participants, intervenors or those making ten minute comments.

Although most people in northwestern British Columbia support the liquified natural gas projects, the prospect of a new Joint Review Panel could likely quickly become controversial in this region. A Coastal GasLink JRP will be the first real test of the restrictions on environmental review imposed on Canada by the Harper government. Environmental groups, especially the few groups that oppose any pipeline projects, will be wary of precedents and likely to test the limits from Bill C-38. Both environmental groups and First Nations will be on alert for any limitations on who can participate in a review. First Nations, even if they support the LNG projects, as most do, will be wary of any attempt by the federal government to limit consultation, rights and title.

A Coastal Gaslink JRP will be a big hot potato for District of Kitimat Council, which has taken a controversial strictly neutral position on the Enbridge Northern Gateway pipeline project until after that Joint Review Panel reports sometime in 2014. Can the District Council now take a positive position on a natural gas pipeline, which from all appearances council supports, long before a Coastal GasLink JRP report (if there is a panel) without facing charges of hypocrisy?

The northwest is in for interesting times.

TransCanada plans rugged over-mountain route for gas pipeline to Kitimat

 

Coastal GasLink map

TransCanada plans a rugged over-mountain route for its proposed Coastal Gaslink pipeline to the Shell Canada liquified natural gas project in Kitimat, BC, company officials said Monday, Oct. 15, 2012, in two presentations, one to District of Kitimat Council and a second at a community town hall briefing.

The pipeline would initially carry 1.7 billion cubic feet of natural gas per day from the Montney Formation region of northeastern British Columbia along a 48 inch (1.2 metre) diameter pipe over 700 kilometres from Groundbirch, near Dawson Creek, to Kitimat, site of the proposed Shell Canada LNG Canada project.

Rick Gateman, President of Coastal GasLink Project, a wholly owned TransCanada subsidiary told council that the project is now at a “conceptual route” stage because TransCanada can’t proceed to actual planning until it has done more detailed survey work and community consultations.

At the same council meeting, documents from Shell Canada notified the District that it has formally applied to the National Energy Board for an export licence for the natural gas.

Rick Gateman

Gateman told council that since the pipeline itself will be completely within the province of British Columbia, it comes under the jurisdiction of the British Columbia Environmental Assessment process and the BC Oil and Gas Commission and that the NEB will not be involved in approving the pipeline itself.

At first, the Coastal Gas Link pipeline would be connected to the existing Nova Gas Transmission system now used (and being expanded) in northeastern British Columbia.

From Vanderhoof, BC to west of Burns Lake, the Coastal GasLink pipeline would be somewhat adjacent to existing pipelines and the route of the proposed Enbridge Northern Gateway bitumen pipeline and the proposed Pacific Trails natural gas pipeline.

Somewhat south of Houston, however, the pipeline takes a different route from the either the Northern Gateway or Pacific Trails Pipeline, going southwest, avoiding the controversial Mount Nimbus route.

Howard Backus, an engineering manager with TransCanada told council that the route changes so that Coastal GasLink can avoid “congestion” in the rugged mountain region.

Backus said that the Pacific Trails Pipeline for Apache and its partners in the Kitimat LNG project “is skirting” Nimbus while Enbridge plans to tunnel through the mountain. That tunnel is one of the most controversial aspects to the Northern Gateway project. The local environmental group Douglas Channel Watch has repeatedly warned of the dangers of avalanche and geological instability in the area where the Northern Gateway pipeline emerges from the tunnel. Enbridge has challenged Douglas Channel Watch’s conclusions in papers filed with the Northern Gateway Joint Review panel.

Under TransCanada’s conceptual route, the pipeline heads southwest and then climbs into the mountains, crossing what Backus calls “a saddle” (not a pass) near the headwaters of the Kitimat River. The pipeline then comes down paralleling Hircsh Creek, emerging close to town, crossing the Kitimat River and terminating at the old Methanex plant where Shell plans its liquified natural gas plant. (That means that if the conceptual plans go ahead, the TransCanada pipeline would climb into the mountains, while Pacific Trails finds a way around and Enbridge tunnels).

Backus told council that going north “created more issues,” but did not elaborate.

Backus assured people at the town hall that energy companies have a lot of experience in building pipelines in mountainous areas, including the Andes in South America.

Asked by a local businessman at the town hall if it was possible to build a road along the route of the pipeline, Backus said the mountain areas would be too steep.  Any pipeline maintenance would have to be done by tracked vehicle, he said.

Gateman told council that the pipeline would be buried along its entire route. If Shell increases the capacity of its LNG facility in Kitimat, the Coastal Gaslink pipeline could increase to 3.4 billion cubic feet a day or perhaps even more. For the initial capacity, the company will have one compressor station at the eastern end of the line. If capacity increases or if the route requires it, there could be as many as five additional compressor stations. (TransCanada’s long term planning is based on the idea that Shell will soon be adding natural gas from the rich Horn River Formation also in northeastern BC to the Kitimat export terminal.)

TransCanada will begin its field work, including route and environmental planning and “community engagement” in 2013 and file for regulatory approval in 2014. Once the project is approved, construction would begin in 2015.

Gateman said that TransCanada is consulting landowners along the proposed right of way and “on a wide area on either side.” The company also is consulting 30 First Nations along the proposed route. Gateman told council, “We probably have the most experience of any number of companies in working directly with and engaging directly with First Nations because of our pipelines across Canada.”

(Despite Gateman’s statement, the TransCanada maps showed that the Coastal Gaslink Pipeline would cross Wet’suwet’en traditional territory and officials seemed to be unaware of the ongoing problems between Apache and the Pacific Trails Pipeline and some Wet’suwet’en Houses who oppose that pipeline).

Gateman told council that the pipeline would be designed to last at least 60 years. He said that in the final test stages, the pipeline would be pressured “beyond capacity” using water rather than natural gas to try and find if any leaks developed during construction.

He said that the company would restore land disrupted by the construction of the pipeline, but noted that it would only restore “low-level vegetation.” Trees are not permitted too close to the pipeline for safety reasons.

TransCanada made the usual promises the region has heard from other companies of jobs, opportunities for local business and wide consultations. (TransCanada may have learned lessons from the botched public relations by the Enbridge Northern Gateway. A number of Kitimat residents have told Northwest Coast Energy News that TransCanada was polling in the region in mid-summer, with callers asking many specific questions about environment and the spinoffs for communities).

Councillor Phil Germuth questioned Gateman about the differences between a natural gas pipeline and a petroleum pipeline. Gateman replied that the pipelines are pretty much the same with the exception that a natural gas pipeline uses compressor stations while a petroleum pipeline uses pumping stations. Gateman did note that the original part of the controversial Keystone XL pipeline that would carry bitumen through Alberta and US mountain states to Texas was a natural gas pipeline converted to carry the heavier hydrocarbons.

Although the natural gas projects have, so far, enjoyed wide support in northwestern British Columbia, environmental groups and First Nations have raised fears that sometime in the future, especially if there is overcapacity in natural gas lines, that some may converted to bitumen, whether or not Northern Gateway is approved and actually goes ahead.

Shell application to NEB

In a fax to District of Kitimat council, Shell Canada Senior Regulatory Specialist Scot MacKillop said that the Shell had applied to the National Energy Board on September 25, 2012 for a licence to export LNG via Kitimat for the next 25 years.

The Shell proposal, like the previous Kitimat LNG and BC LNG proposals, are export applications, unlike the Enbridge Northern Gateway which is a “facility application.”
In its letter to Shell’s lawyers, the NEB took pains to head off any objections to the project on environmental or other grounds by saying:

the Board will assess whether the LNG proposed to exported does not exceed the surplus reaming after due allowance has been made for the reasonably foreseeable requirements for use in Canada. The Board cannot consider comments that are unrelated…such as those relating to potential environmental effects of the proposed exportation and any social effects that would be directly related to those environmental effects.

New US pipeline safety report finds more problems with Enbridge, problems also found in other big pipeline companies

Leak detection report coverA new draft report for the U.S. Congress from the United States Pipeline and Hazardous Materials Safety Administration takes new aim at Enbridge for failures in its pipeline leak detection and response system.

Not that the PHMSA is singling out Enbridge, the report is highly critical of leak detection systems on all petroleum and natural gas pipeline companies, saying as far as the United States is concerned, the current pipeline standards are inadequate.

The release of the “Leak Detection Report” written by Kiefner & Associates, Inc (KAI) a consulting firm based in Worthington, Ohio, comes at a critical time, just as Enbridge was defending how it detects pipeline leaks before the Joint Review Panel questioning hearings in Prince George, where today Enbridge executives were under cross-examination by lawyers for the province of British Columbia on how the leak detection system works.

In testimony on Wednesday, October 12, Enbridge engineers told the Joint Review Panel that the company’s pipelines are world-class and have a many prevention and detection systems.

Northern Gateway president John Carruthers testifed there is no way to eliminate all the risks but the company was looking for the best way of balancing benefits against the risk.

However, the KAI report points out that so far, all pipeline company cost-benefit analysis is limited by a short term, one to five year point of view, rather than looking at the entire lifecycle of a pipeline.

Two Enbridge spills, one the well-known case in Marshall Michigan which saw bitumen go into the Kalamazoo River and a second in North Dakota, both in 2010, are at the top of the list in the study for PHMSA by the consulting firm.

On the Marshall, Michigan spill the KAI report goes over and adds to many of the criticisms of Enbridge in the National Transportation Safety Report in July which termed the company’s response like the “Keystone Kops.”

The second spill, in Neche, North Dakota, which, unlike the Marshall spill, has had little attention from the media, is perhaps equally damning, because while Enbridge’s detection systems worked in that case–the KAI report calls it a “text book shutdown”– there was still a spill of 158,928 gallons (601,607 litres) of crude oil, the sixth largest hazardous liquid release reported in the United States [between 2010 and 2012] because Enbridge “did not plan adequately for containment.”

(The KAI report also examines problems with natural gas pipelines, including one by TransCanada Northern Border line at Campbell, Wyoming in February 2011. Northwest Coast Energy News will report on the natural gas aspects of the report in a future posting.)

The highly technical, 270-page draft report was released on September 28, as Enbridge was still under heavy criticism from the US National Transportation Safety Board report on the Marshall, Michigan spill and was facing penalties from the PHMSA for both the Marshall spill and a second in Ohio.

Looking at overall pipeline problem detection, KAI says the two standard industry pipeline Leak Detection Systems or LDS didn’t work very well. Between 2010 and 2012, the report found that Computational Pipeline Monitoring or CPMs caught just 20 per cent of leaks. Another system, Supervisory Control and Data Acquisition or SCADAs caught 28 per cent.
Even within those acronym systems, the KAI report says major problem is a lack of industry standards. Different companies use different detector and computer systems, control room procedures and pipeline management.

The report also concludes that the pipeline industry as a whole depends far too much on internal detectors, both for economic reasons and because that’s what the industry has always done. External detectors, the report says, have a better track record in alerting companies to spills.

A significant number of spills are also first reported by the public or first responders, rather than through the pipeline company system and as KAI says of Enbridge, “Operators should not rely on the public to tell them a pipeline has ruptured.”

The consultants also say there are far too many false alarms in spill detection systems.

Although the KAI report concentrates on the United States, its report on Enbridge does raise serious questions about how the company could detect a pipeline breach or spill in the rugged northern British Columbia wilderness where the Northern Gateway Pipeline would be built, if approved by the federal government.

The report comes after the United States Congress passed The Pipeline Safety, Regulatory Certainty, and Job Creation Act, which was signed into law by President Barack Obama on January 3, 2012. The law called on a new leak detection study to be submitted to Congress that examines the technical limitations of current leak detection systems, including the ability of the systems to detect ruptures and small leaks that are ongoing or intermittent. The act also calls on the US Department of Transportation to find out what can be done to foster development of better technologies and economically feasible ways of detecting pipeline leaks. The final report must be submitted to Congress by January 3, 2013.

(The draft report does note in some ways, Canadian standards for detecting pipeline leaks are better than those in the United States. For example, Canada requires some pipeline testing every year, the United States every five years. It also finds European pipeline monitoring regulations also surpass those in the United States).

The spills studied in the report all found weaknesses in one or more of those three areas: people, company procedures and the technology. It appears that the industry agrees, at least in principle, with executives telling the consultants:

The main identified technology gaps – including those identified by operators – include: reduction or management of false alarms; applicable technical standards and certifications; and value / performance indicators that can be applied across technologies and pipelines.

The report echoes many of the findings of the US National Transportation Safety Board in its examination of the Enbridge Marshall, Michigan spill but it applies to all pipeline companies, noting:

Integration using procedures is optimal when it is recognized that alarms from the technology are rarely black-and-white or on/off situations. Rather, at a minimum, there is a sequence: leak occurrence; followed by first detection; followed by validation or confirmation of a leak; followed by the initiation of a shutdown sequence. The length of time that this sequence should take depends on the reliability of the first detection and the severity of the consequences of the release. Procedures are critical to define this sequence carefully – with regard to the technology used, the personnel involved and the consequences – and carefully trained Personnel are needed who understand the overall system, including technologies and procedures.

We note that there is perhaps an over-emphasis of technology in LDS. A recurring theme is that of false alarms. The implication is that an LDS is expected to perform as an elementary industrial automation alarm, with an on/off state and six-sigma reliability. Any alarm that does not correspond to an actual leak is, with this thinking, an indicator of a failure of the LDS system.

Instead, multiple technical studies confirm that far more thought is required in dealing with leak alarms. Most technologies infer the potential presence of a leak via a secondary physical effect, for example an abnormal pressure or a material imbalance. These can often be due to multiple other causes apart from a leak.

The report takes a critical look at the culture of all pipeline companies which divides problems into leaks, ruptures and small seeps. Under both pipeline practice and the the way problems are reported to the PHMSA in the US a “rupture is a situation where the pipeline becomes inoperable.” While a rupture means that a greater volume of petroleum liquid or natural gas is released, and is a higher priority than a leak or seep, the use of language may mean that there is a lower priority given to those leaks and seeps than the crisis created by a rupture.

(Environmental groups in British Columbia have voiced concerns about the cumulative affect of small seeps from the Enbridge Northern Gateway that would be undetectable under heavy snow pack either by an internal system or by external observation)

Overall, the report finds serious flaws to the way pipeline companies are conducting leak detection systems at the moment, including:

  • Precisely the same technology, applied to two different pipelines, can have very different results.
  • Leak Detection Systems do not have performance measures that can be used universally across all pipelines. Compounding the problem are different computer systems where software, program configuration and parameter selection all contribute, in unpredictable ways, to overall performance.
  • Many performance measures present conflicting objectives. For example, leak detection systems that are highly sensitive to small amounts of lost hydrocarbons are also prone to generating more false alarms.
  • The performance of a leak detection system depends critically on the quality of the engineering design, care with installation, continuing maintenance and periodic testing.
  • Even though an internal technology may rely upon simple, basic principles, it is in fact, complex system that requires robust metering, robust SCADA and telecommunications, and a robust computer to perform the calculations. Each of these subsystems is individually complex.
  • Near the inlet and the outlet of the pipeline a leak leads to little or no change in pressure. Flow rates and pressures near any form of pumping or compression will generally be insensitive to a downstream leak
  • Differences in any one of these factors can have a dramatic impact on the ultimate value of a leak detection system.

The report goes on to  say:

There is no technical reason why several different leak detection methods can not be implemented at the same time. In fact, a basic engineering robustness principle calls for at least two methods that rely on entirely separate physical principles.

The report strongly recommends that pipeline companies take a closer look at external leak detection systems. Even though the US Environmental Protection Agency began recommending the use of external detection as far back as 1988, the companies have resisted due to the cost of retrofitting the legacy pipeline network. (Of course if the pipeline companies had started retrofitting with external detectors in 1988 they would be now 24 years into the process).

KAI says:

  • External leak detection is both very simple – relying upon routinely installed external sensors that rely upon at most seven physical principles – and also confusing, since there is a wide range of packaging, installation options, and operational choices to be considered.
  • External leak detection sensors depend critically on the engineering design of their deployment and their installation.
  • External sensors have the potential to deliver sensitivity and time to detection far ahead of any internal system.
  • Most technologies can be retrofitted to existing pipelines. In general, the resistance to adopting external technologies is, nevertheless, that fieldwork on a legacy pipeline is relatively expensive.
  • The report goes on to identify major bureaucratic roadblocks within pipeline companies. Like many other big corporations, walls exist that prevent the system from working well
  • A particular organizational difficulty with leak detection is identifying who “owns” the leak detection system on a pipeline. A technical manager or engineer in charge is typically appointed, but is rarely empowered with global budgetary, manpower or strategic responsibilities. Actual ownership of this business area falls variously to metering, instrumentation and control, or IT.

The report calls for better internal standards at pipeline companies since with leak detection “one size does not necessarily fit all”.

It also notes that “flow metering is usually a central part of most internal leak detection systems,” but adds “flow meter calibration is by far the most laborious part of an internal system’s maintenance.

Also, the central computer and software technology usually has maintenance requirements far greater than most industrial automation and need special attention.”

While a company may do a cost benefit analysis of its leak detection system and risk reduction system it will generally emphasize the costs of the performance and engineering design of the leak detection system, the companies usually place less emphasis on the benefits of a robust system, especially the long term benefits.

At present the pipeline companies look at the benefit of leak detection as a reduction in risk exposure, or asset liability, “a hard, economic definition… understood by investors.” But the report adds that leak detection systems have a very long lifetime and over that life cycle, the cost-benefit approaches the reduction in asset liability caused by the system, when divided by annual operational costs. However, since pipeline companies budget on a one to five year system the long term benefit of robust, and possibly expensive spill detection is not immediately apparent.

Enbridge

The consultants studied 11 US oil spills, the top two with the greatest volume were from Enbridge pipelines. The others were from TE Products Pipeline, Dixie Pipeline, Sunoco, ExxonMobil, Shell, Amoco, Enterprise Products, Chevron and Magellan Pipeline. Not all US spills were used in the KAI report, the 11 were chosen for availability of data and documentation.

The largest spill in the KAI study was the pipeline rupture in Michigan at 843,444 gallon (3,158,714 litres) which has been the subject of continuing media, investigative and regulatory scrutiny. The second spill in North Dakota, has up to now received very little attention from the media. That will likely change once the US Congress gets the final report. Even though the Neche, North Dakota spill, has been described as “text book case” of a pipeline shutdown, there was still a large volume of oil released.

Marshall, Michigan spill

On the Marshall, Michigan spill that sent bitumen into the Kalamazoo River the report first goes over the facts of the 843,444 gallon spill and the subsequent release of a highly critical report from the US National Transportation Safety Board. It then looks at the failures of Enbridge’s detection system from the point of view mandated for the report to Congress:

The pipeline was shutting down when the ruptured occurred. Documentation indicates that a SCADA alarm did sound coincident with the most likely time of the rupture. It was dismissed. The line was shut down for around 10 hrs and crude oil would have drained from the line during this time.

On pipeline start up, alarms in the control room for the ruptured pipeline sounded. They were dismissed. This was repeated two more times. The pipeline was shut down when the control room was notified of the discharge of the crude oil by a member of the public. The time to shut down the pipeline is not relevant here because of the 17 hours that elapsed after the rupture occurred.

The review identified issues at Enbridge relevant to this Leak Detection Study:

1. Instrumentation on a pipeline that informs a controller what is happening to the pipeline must be definitive in all situations.
2. However, the instrumentation did provide warnings which went unheeded by controllers.
3. Instrumentation could be used to prevent a pump start up.
4. Operators should not rely on the public to tell them when a pipeline has ruptured.
5. Pipeline controllers need to be fully conversant with instrumentation response to different operations performed on the pipeline.
6. If alarms can be cancelled there is something wrong with the instrumentation feedback loop to the controller. This is akin to the low fuel warning on a car being turned off and ignored. The pipeline controller is part of an LDS and failure by a controller means the LDS has failed even if the instrumentation is providing correct alarms.
7. If the first SCADA alarm had been investigated, up to 10 hours of pipeline drainage to the environment might have been avoided. If the second alarm had been investigated, up to 7 hours of pumping oil at almost full capacity into the environment might have been avoided.
8. CPM systems are often either ignored or run at much higher tolerances during pipeline start ups and shutdowns, so it is probable that the CPM was inoperative or unreliable. SCADA alarms, on the other hand, should apply under most operating conditions.

Neche, North Dakota spill

At approximately 11:37 pm. local time, on January 8, 2010, a rupture occurred on Enbridge’s Line 2, resulting in the release of approximately 3000 barrels or 158,928 gallons of crude oil approximately 1.5 miles northeast of the town of Neche, North Dakota, creating the sixth largest spill in the US during the study period.

As the report notes, in this case, Enbridge’s detection system worked:

At 11:38 pm., a low-suction alarm initiated an emergency station cascade shutdown. At 11:40 pm., the Gretna station valve began closing. At 11:44 pm., the Gretna station was isolated. At 11:49 pm., Line 2 was fully isolated from the Gretna to Donaldson pump stations.

Documentation indicates a rapid shut down on a low suction alarm by the pipeline controller. From rupture to shut down is recorded as taking 4 minutes. The length of pipeline isolated by upstream and downstream remotely controlled valves was 220,862 feet. The inventory for this length of line of 26-inch diameter is 799,497 gallons. The release amount was around 20 per cent of the isolated inventory when the pipeline was shut down.

The orientation of the 50-inch long rupture in the pipe seam is not known. The terrain and elevation of the pipeline is not known. The operator took around 2 hours and 40 minutes to arrive on site. It is surmised that the rupture orientation and local terrain along with the very quick reactions by the pipeline controller may have contributed to the loss of around 20 per cent of the isolated inventory.

The controller was alerted by the SCADA. Although a CPM system was functional the time of the incident it did not play a part in detecting the release event. It did provide confirmation.

But the KAI review identified a number of issues, including the fact in item (7) Enbridge did not plan for for containment and that containment systems were “under-designed.”

1. This release is documented as a text book shut down of a pipeline based on a SCADA alarm.
2. The LDS did not play a part in alerting the pipeline controller according to
documentation. However, leak detection using Flow/Pressure Monitoring via SCADA
worked well.
3. Although a textbook shut down in 4 minutes is recorded, a large release volume still occurred.
4. The release volume of 158,928 gallons of crude oil is the sixth largest hazardous liquid release reported between January 1, 2010 and July 7, 2012.
5. The length of pipeline between upstream and downstream isolation valves is long at 41.8 miles.
6. If not already performed, the operator should review potential release volumes based on ruptures taking place at different locations on the isolated section.
7. The success of a leak detection system includes planning for the entire process: detection through shutdown through containment. In this case, the operator did not plan adequately for containment so that although the SCADA leak detection technology, the controller and the procedures worked well, the containment systems (isolation valves) were under-designed and placed to allow a very large spill.”
