Update 5:30 p.m.
The NRDC responded to the ECRB statement saying they "stand by the information provided in the report - which is well documented and reviewed." From the NRDC statement:
The lack of transparency from the oil industry is part of the issue here. A clear accounting of the public health and safety issues associated with these products and the infrastructure associated with them is simply not available. The example of Enbridge’s CEO denying tar sands were involved with the Kalamazoo River disaster until pushed by reporters with undeniable evidence is one example of this lack of transparency.
Update 2:55 p.m.
The Energy Resources Conservation Board of Alberta, Canada, "an agency that regulates the province's energy resources," has issued a response to the report.
They write that the report "contains misleading statements on pipeline safety in Alberta and on the characteristics of diluted bitumen." From ERCB statement:
The report also states that “there are many indications that DilBit is significantly more corrosive to pipeline systems than conventional crude.” Analysis of pipeline failure statistics in Alberta has not identified any significant differences in failure frequency between pipelines handling conventional crude versus pipelines carrying crude bitumen, crude oil or synthetic crude oil.
This past summer, an oil pipeline in Michigan spilled more than 843,000 gallons of crude oil into Talmadge Creek and the Kalamazoo River.
The spill is still being cleaned up by Enbridge Energy Partners, the company responsible for the spill.
Now, a new report says the type of oil running through the pipeline could lead to more spills.
