COMMITMENTS AND CONTINGENCIES

Indemnification

Under the Amended Omnibus Agreement, Tesoro indemnifies us for certain matters, including environmental, title and tax matters associated with the ownership of our assets at or before the closing of the Initial Offering and subsequent acquisitions from Tesoro, excluding the Los Angeles Terminal Assets and the Los Angeles Logistics Assets. Under the Carson Assets Indemnity Agreement, Tesoro retained responsibility for remediation of known environmental liabilities due to the use or operation of the Los Angeles Terminal Assets and the Los Angeles Logistics Assets prior to the acquisition dates, and has indemnified the Partnership for any losses incurred by the Partnership arising out of those remediation obligations. See Note J of our Annual Report on Form 10-K for the year ended December 31, 2013 for additional information regarding the terms and conditions of the Amended Omnibus Agreement and the Carson Assets Indemnity Agreement.

Environmental Liabilities

We are subject to federal, state and local laws and regulations governing environmental quality and pollution control. These laws and regulations require us to remove or remedy the effect of the disposal or release of specified substances at current and former operating sites. We have accrued liabilities for these expenses and believe these accruals are adequate based on current information and projections that can be reasonably estimated. Our environmental accruals are based on estimates including engineering assessments, and it is possible that our projections will change and that additional costs will be recorded as more information becomes available. Our accruals for these environmental expenditures totaled $23.0 million and $24.4 million at June 30, 2014 and December 31, 2013, respectively. Changes in our environmental liabilities during the period were as follows (in thousands):



	Tioga Crude Oil Pipeline Release			Chevron Corrective Action Order			Other Liabilities			Total
Balance at December 31, 2013	$	11,568		$	8,016		$	4,856		$	24,440
Additions	5,636			—			571			6,207
Expenditures	(2,122		)	(5,159		)	(325		)	(7,606		)
Balance at June 30, 2014	$	15,082		$	2,857		$	5,102		$	23,041

Tioga, North Dakota Crude Oil Pipeline Release

In September 2013, the Partnership responded to the release of approximately 20,000 barrels of crude oil in a rural field northeast of Tioga, North Dakota (the “Crude Oil Pipeline Release”). The environmental liabilities related to the Crude Oil Pipeline Release include amounts estimated for remediation activities that will be conducted during the next few years to restore the site for agricultural use. We accrued an additional $5.6 million during the six months ended June 30, 2014 to reflect improved scope definition and estimates which resulted in an increase in the total estimated cost associated with the project. Probable insurance recoveries related to the Crude Oil Pipeline Release of $17.2 million and $14.0 million were included in other receivables at June 30, 2014 and December 31, 2013, respectively, pursuant to a pollution liability insurance policy, which is subject to a $1.0 million deductible and a $25.0 million loss limit. Through June 30, 2014, we have received insurance proceeds of $2.4 million in reimbursement of costs incurred.

Costs to comply with a safety order related to the Crude Oil Pipeline Release issued by the Pipeline and Hazardous Materials Safety Administration of the U.S. Department of Transportation (“PHMSA”) are not expected to have a material adverse effect on our liquidity, financial position or results of operations.

Chevron Diesel Pipeline Release

On March 18, 2013, Chevron detected and responded to the release of diesel fuel (the “Diesel Pipeline Release”) that occurred near Willard, Utah on the Northwest Products System. As a result of this release, a Corrective Action Order (the “CAO”) was issued on March 22, 2013 by PHMSA. In addition, on April 11, 2013, the Department of Environmental Quality, Division of Water Quality, of the state of Utah issued a notice of violation and compliance order. In accordance with the sale and purchase agreements related to the Northwest Products System acquisition, as amended, Chevron retains financial and operational responsibility to remediate the site of the Diesel Pipeline Release through mid-2015, in addition to paying any monetary fines and penalties assessed by any government authority arising from this incident.

The Partnership assumed responsibility for performing additional testing and associated pipeline repairs on the pipeline pursuant to the CAO upon closing the Northwest Products System acquisition. In connection with the Northwest Products System acquisition, our condensed consolidated balance sheet included $2.9 million and $8.0 million in accrued environmental liabilities related to the CAO at June 30, 2014 and December 31, 2013, respectively, and $4.9 million and $4.7 million in accruals unrelated to the Diesel Pipeline Release included in other noncurrent liabilities at June 30, 2014 and December 31, 2013, respectively.

Contingencies

In the ordinary course of business, we may become party to lawsuits, administrative proceedings and governmental investigations, including environmental, regulatory and other matters. The outcome of these matters cannot always be predicted accurately, but TLLP will accrue liabilities for these matters if the amount is probable and can be reasonably estimated. Other than described above, we did not have any material lawsuits, administrative proceedings or governmental investigations.
