We incurred no expense for environmental remediation obligations for the three months ended September 30, 2015 and 2014. For the nine months ended September 30, 2015 and 2014, we incurred expenses of $4.2 million and $0.7 million, respectively, for environmental remediation obligations. During the nine months ended September 30, 2015, we increased certain environmental cost accruals to reflect revisions to the cost estimates and the time frame for which the related environmental remediation and monitoring activities are expected to occur. The accrued environmental liability reflected in our consolidated balance sheets was $14.9 million and $12.0 million at September 30, 2015 and December 31, 2014, respectively, of which $12.0 million and $8.7 million, respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of September 30, 2015, and December 31, 2014, our accrued environmental liability included $6.4 million and $6.8 million, respectively, for HFC indemnified liabilities. In addition, as of September 30, 2015, and December 31, 2014, $6.4 million and $6.8 million, respectively, was included in other assets representing amounts due from HFC related to indemnifications for environmental remediation liabilities.
