Commitments and Contingencies
We have long-term lease commitments for land, office facilities, retail facilities and related equipment and various equipment and facilities used in the storage and transportation of refined products. We also have long-term lease commitments for land at our Krotz Springs refinery. In most cases we expect that in the normal course of business, our leases will be renewed or replaced by other leases. We have commitments under long-term operating leases for certain buildings, land, equipment and pipelines expiring at various dates over the next nineteen years. Certain long-term operating leases relating to buildings, land and pipelines include options to renew for additional periods. At December 31, 2016, minimum lease payments on operating leases were as follows:
Total rental expense was $41,156, $40,811 and $35,699 for the years ended December 31, 2016, 2015 and 2014, respectively. Contingent rentals and subleases were not significant.
In the normal course of business, we have long-term commitments to purchase, at market prices, utilities such as natural gas, electricity and water for use by our refineries, terminals, pipelines and retail locations. We are also party to various refined product and crude oil supply and exchange agreements, which are typically short-term in nature or provide terms for cancellation.
We have a pipelines and terminals agreement with Holly Energy Partners (“HEP”) through February 2020 with three additional five-year renewal terms exercisable at our sole option. Pursuant to the pipelines and terminals agreement, we have committed to transport and store minimum volumes of refined products in these pipelines and terminals. The tariff rates applicable to the transportation of refined products on the pipelines are variable, with a base fee which is reduced for volumes exceeding defined volumetric targets. The agreement provides for the reduction of the minimum volume requirement under certain circumstances. Our minimum commitment under this agreement is $24,573 for 2017. The service fees for the storage of refined products in the terminals are set at rates competitive in the marketplace.
We have a throughput and deficiency agreement with Sunoco Pipeline, LP (“Sunoco”) that gives us the option to transport crude oil through the Amdel Pipeline either (1) westbound from the Nederland Terminal to the Big Spring refinery, or (2) eastbound from the Big Spring refinery to the Nederland Terminal for further barge transportation to the Krotz Springs refinery. Our minimum throughput commitment is 15,645 bpd which is a $14,254 commitment for 2017. The agreement is for five years from the operational date of September 2012 with an option to extend the agreement by four additional thirty-month periods.
We have an arrangement with Centurion Pipeline L.P. (“Centurion”) through June 2021. This arrangement gives us transportation pipeline capacity to ship crude oil from Midland to the Big Spring refinery using Centurion’s approximately forty-mile long pipeline system from Midland to Roberts Junction and our three-mile pipeline from Roberts Junction to the Big Spring refinery which we lease to Centurion. Our minimum throughput commitment is 25,000 bpd which is a $2,454 commitment for 2017.
We have entered into a transportation services agreement with Navigator Energy Services, LLC (“Navigator”), which provides for the construction and operation of a pipeline system to facilitate delivery of crude oil to the Big Spring refinery from a number of injection points in the area of the refinery. The term of the agreement begins upon the commencement of shipments and continues for an initial period of ten years, with two additional five-year renewal terms exercisable at our sole option. Our minimum throughput commitment is 10,000 bpd which is a $2,144 commitment for 2017.
We have offtake agreements with two investment grade oil companies that provides for the sale, at market prices, of high sulfur distillate blendstock and light cycle oil, through June and September 2017. Both agreements will automatically extend for successive one-year terms unless either we or the other party cancels the agreement by delivering written notice of termination to the other at least 180 days prior to the end of the then current term.
We are involved in various legal actions arising in the ordinary course of business. We believe the ultimate disposition of these matters will not have a material effect on our financial position, results of operations or liquidity.
One of our subsidiaries is a party to a lawsuit alleging breach of contract pertaining to an asphalt supply agreement. We believe that we have valid counterclaims as well as affirmative defenses that will preclude recovery. Attempts to reach a commercial arrangement to resolve the dispute have been unsuccessful to this point. This matter is not currently scheduled for trial. Due to the uncertainties of litigation, we cannot predict with certainty the ultimate resolution of this lawsuit.
We are subject to loss contingencies pursuant to federal, state, and local environmental laws and regulations. These laws and regulations govern the discharge of materials into the environment and may require us to incur future obligations to investigate the effects of the release or disposal of certain petroleum, chemical, and mineral substances at various sites; to remediate or restore these sites and to compensate others for damage to property and natural resources. These contingent obligations relate to sites that we own and are associated with past or present operations. We are currently participating in environmental investigations, assessments and cleanups pertaining to our refineries, service stations, pipelines and terminals. We may be involved in additional future environmental investigations, assessments and cleanups. The magnitude of future costs are unknown and will depend on factors such as the nature and contamination at many sites, the timing, extent and method of the remedial actions which may be required, and the determination of our liability in proportion to other responsible parties.
We have an environmental agreement with HEP pursuant to which we agreed to indemnify HEP against costs and liabilities incurred by HEP to the extent resulting from the existence of environmental conditions at the pipelines or terminals or from violations of environmental laws with respect to the pipelines and terminals occurring prior to February 28, 2005. Our environmental indemnification obligations under the environmental agreement expired on March 1, 2015. However, with respect to any remediation required for environmental conditions existing prior to February 28, 2005, we have the option under the environmental agreement to perform such remediation ourselves in lieu of indemnifying HEP for their costs of performing such remediation. Pursuant to this option, we are continuing to perform the ongoing remediation at the Abilene and Wichita Falls terminals. Any remediation required under the terms of the environmental agreement is limited to the standards under the applicable environmental laws as in effect at February 28, 2005.
We have an environmental agreement with Sunoco pursuant to which we agreed to indemnify Sunoco against costs and liabilities incurred by Sunoco to the extent resulting from the existence of environmental conditions at the pipelines or from violations of environmental laws with respect to the pipelines occurring prior to March 1, 2006. With respect to any remediation required for environmental conditions existing prior to March 1, 2006, we have the option to perform such remediation ourselves in lieu of indemnifying Sunoco for their costs of performing such remediation.
We have accrued environmental remediation obligations of $45,636 ($4,237 current liability and $41,399 non-current liability) at December 31, 2016, and $46,362 ($7,880 current liability and $38,482 non-current liability) at December 31, 2015. Environmental liabilities with payments that are fixed or reliably determinable have been discounted to present value at a rate of 2.62%.
The table below summarizes our environmental liability accruals:
As of December 31, 2016, the estimated future payments of environmental obligations for which discounts have been applied are as follows:
We have an indemnification agreement with a prior owner for part of the remediation expenses at certain West Coast assets. We have recorded current receivables of $644 and $623 and non-current receivables of $2,762 and $2,648 at December 31, 2016 and 2015, respectively.
