Contingencies

We are not currently a party to any material legal proceedings. However, NuStar Energy is subject to certain loss contingencies, the outcome of which could have an effect on NuStar Energy’s results of operations and ability to pay distributions, which would impact our results of operations and ability to pay distributions. NuStar Energy’s material contingent liabilities resulting from various litigation, claims and commitments are discussed below.

Grace Energy Corporation Matter. In 1997, Grace Energy Corporation (Grace Energy) sued subsidiaries of Kaneb Pipeline Partners, L.P. (KPP) and Kaneb Services LLC (KSL and collectively with KPP and their respective subsidiaries, Kaneb) in Texas state court. NuStar Energy acquired Kaneb on July 1, 2005. The complaint sought recovery of the cost of remediation of fuel leaks in the 1970s from a pipeline that had once connected a former Grace Energy terminal with Otis Air Force Base in Massachusetts (Otis AFB). Grace Energy alleges the Otis AFB pipeline and related environmental liabilities had been transferred in 1978 to an entity that was part of Kaneb’s acquisition of Support Terminal Services, Inc. and its subsidiaries from Grace Energy in 1993. Kaneb contends that it did not acquire the Otis AFB pipeline and never assumed any responsibility for any associated environmental damage.

In 2000, the court entered final judgment that: (i) Grace Energy could not recover its own remediation costs of $3.5 million, (ii) Kaneb owned the Otis AFB pipeline and its related environmental liabilities and (iii) Grace Energy was awarded $1.8 million in attorney costs. Both Kaneb and Grace Energy appealed the final judgment of the trial court to the Texas Court of Appeals in Dallas. In 2001, Grace Energy filed a petition in bankruptcy, which created an automatic stay of actions against Grace Energy. In September 2008, Grace Energy filed its Joint Plan of Reorganization and Disclosure Statement.

The Otis AFB is a part of a Superfund Site pursuant to the Comprehensive Environmental Response Compensation and Liability Act (CERCLA). The site contains a number of groundwater contamination plumes, two of which are allegedly associated with the Otis AFB pipeline. Relying on the final judgment of the Texas state court assigning ownership of the Otis AFB pipeline to Kaneb, the United States Department of Justice (the DOJ) advised Kaneb in 2001 that it intends to seek reimbursement from Kaneb for the remediation costs associated with the two plumes. In November 2008, the DOJ forwarded information to NuStar Energy indicating that the past and estimated future remediation expenses associated with one plume are $71.9 million. NuStar Energy reached an agreement to settle the claims of the United States government with respect to the Otis AFB pipeline and to resolve the underlying dispute between Kaneb and Grace. The settlement was approved by the United States Bankruptcy Court for the District of Delaware and a consent decree was entered by the United States District Court for the District of Massachusetts. Pursuant to the terms of the settlement, NuStar Energy paid approximately $13.1 million to the United States government in July 2012 and received releases of claims from various private parties and a covenant not to sue from the United States government. In connection with the settlement, NuStar Energy recognized a gain of $28.7 million during the second quarter of 2012.

Other.NuStar Energy is a party to additional claims and legal proceedings arising in the ordinary course of its business. Due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on NuStar Energy’s results of operations, financial position or liquidity.
