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

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

In its quarterly report Enbridge said

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

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

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

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

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

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

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

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

Insurance renewed

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

It adds:

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

All Enbridge figures are in US dollars

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