Environmental Remediation Obligations [Abstract] |
Environmental Obligations | NOTE 6. — ENVIRONMENTAL OBLIGATIONS We are subject to numerous federal, state and local laws and regulations, including matters relating to the protection of the environment such as the remediation of known contamination and the retirement and decommissioning or removal of long-lived assets including buildings containing hazardous materials, USTs and other equipment. Environmental costs are principally attributable to remediation costs which are incurred for, among other things, removing USTs, excavation of contaminated soil and water, installing, operating, maintaining and decommissioning remediation systems, monitoring contamination and governmental agency compliance reporting required in connection with contaminated properties. We enter into leases and various other agreements which contractually allocate responsibility between the parties for known and unknown environmental liabilities at or relating to the subject properties. We are contingently liable for these environmental obligations in the event that our tenant does not satisfy them, and we are required to accrue for environmental liabilities that we believe are allocable to others under our leases if we determine that it is probable that our tenant will not meet its environmental obligations. It is possible that our assumptions regarding the ultimate allocation method and share of responsibility that we used to allocate environmental liabilities may change, which may result in material adjustments to the amounts recorded for environmental litigation accruals and environmental remediation liabilities. We assess whether to accrue for environmental liabilities based upon relevant factors including our tenants’ histories of paying for such obligations, our assessment of their financial cap ability, and their intent to pay for such obligations. However, there can be no assurance that our assessments are correct or that our tenants who have paid their obligations in the past will continue to do so. We may ultimately be responsible to pay for environmental liabilities as the property owner if our tenant fails to pay them. The estimated future costs for known environmental remediation requirements are accrued when it is probable that a liability has been incurred and a reasonable estimate of fair value can be made. The accrued liability is the aggregate of our estimate of the fair value of cost for each component of the liability, net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. For substantially all of our triple-net leases, our tenants are contractually responsible for compliance with environmental laws and regulations, removal of USTs at the end of their lease term (the cost of which in certain cases is partially borne by us) and remediation of any environmental contamination that arises during the term of their tenancy. Under the terms of our leases covering properties previously leased to Marketing (substantially all of which commenced in 2012), we have agreed to be responsible for environmental contamination at the premises that was known at the time the lease commenced, and for environmental contamination which existed prior to commencement of the lease and is discovered (other than as a result of a voluntary site investigation) during the first 10 years of the lease term (or a shorter period for a minority of such leases). After expiration of such 10-year (or, in certain cases, shorter) period, responsibility for all newly discovered contamination, even if it relates to periods prior to commencement of the lease, is contractually allocated to our tenant. Our tenants at properties previously leased to Marketing are in all cases responsible for the cost of any remediation of contamination that results from their use and occupancy of our properties. Under substantially all of our other triple-net leases, responsibility for remediation of all environmental contamination discovered during the term of the lease (including known and unknown contamination that existed prior to commencement of the lease) is the responsibility of our tenant. We anticipate that a majority of the USTs at properties previously leased to Marketing will be replaced over the next several years because these USTs are either at or near the end of their useful lives. For long-term, triple-net leases covering sites previously leased to Marketing, our tenants are responsible for the cost of removal and replacement of USTs and for remediation of contamination found during such UST removal and replacement, unless such contamination was found during the first 10 years of the lease term and also existed prior to commencement of the lease. In those cases, we are responsible for costs associated with the remediation of such preexisting contamination. We have also agreed to be responsible for environmental contamination that existed prior to the sale of certain properties assuming the contamination is discovered (other than as a result of a voluntary site investigation) during the first five years after the sale of the properties. In the course of certain UST removals and replacements at properties previously leased to Marketing where we retained continuing responsibility for preexisting environmental obligations, previously unknown environmental contamination was and continues to be discovered. As a result, we have developed an estimate of fair value for the prospective future environmental liability resulting from preexisting unknown environmental contamination and have accrued for these estimated costs. These estimates are based primarily upon quantifiable trends which we believe allow us to make reasonable estimates of fair value for the future costs of environmental remediation resulting from the removal and replacement of USTs. Our accrual of the additional liability represents our estimate of the fair value of cost for each component of the liability, net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. In arriving at our accrual, we analyzed the ages of USTs at properties where we would be responsible for preexisting contamination found within 10 years after commencement of a lease (for properties subject to long-term triple-net leases) or five years from a sale (for divested properties), and projected a cost to closure for preexisting unknown environmental contamination. We measure our environmental remediation liabilities at fair value based on expected future net cash flows, adjusted for inflation (using a range of 2.0% to 2.75%), and then discount them to present value (using a range of 4.0% to 7.0%). We adjust our environmental remediation liabilities quarterly to reflect changes in projected expenditures, changes in present value due to the passage of time and reductions in estimated liabilities as a result of actual expenditures incurred during each quarter. As of June 30, 2021, we had accrued a total of $47,932,000 for our prospective environmental remediation obligations. This accrual consisted of (a) $11,920,000, which was our estimate of reasonably estimable environmental remediation liability, including obligations to remove USTs for which we are responsible, net of estimated recoveries and (b) $36,012,000 for future environmental liabilities related to preexisting unknown contamination. As of December 31, 2020, we had accrued a total of $48,084,000 for our prospective environmental remediation obligations. This accrual consisted of (a) $11,718,000, which was our estimate of reasonably estimable environmental remediation liability, including obligations to remove USTs for which we are responsible, net of estimated recoveries and (b) $36,366,000 for future environmental liabilities related to preexisting unknown contamination. Environmental liabilities are accreted for the change in present value due to the passage of time and, accordingly, $863,000 and $922,000 of net accretion expense was recorded for the six months ended June 30, 2021 and 2020, respectively, which is included in environmental expenses. In addition, during the six months ended June 30, 2021 and 2020, we recorded credits to environmental expenses aggregating $1,039,000 and $1,228,000, respectively, where decreases in estimated remediation costs exceeded the depreciated carrying value of previously capitalized asset retirement costs. Environmental expenses also include project management fees, legal fees and environmental litigation accruals. For the six months ended June 30, 2021 and 2020, changes in environmental estimates aggregating, $92,000 and $73,000, respectively, were related to properties that were previously disposed of by us. During the six months ended June 30, 2021 and 2020, we increased the carrying values of certain of our properties by $1,211,000 and $1,441,000, respectively, due to changes in estimated environmental remediation costs. The recognition and subsequent changes in estimates in environmental liabilities and the increase or decrease in carrying values of the properties are non-cash transactions which do not appear on our consolidated statements of cash flows. Capitalized asset retirement costs are being depreciated over the estimated remaining life of the UST, a 10-year period if the increase in carrying value is related to environmental remediation obligations or such shorter period if circumstances warrant, such as the remaining lease term for properties we lease from others. Depreciation and amortization expense related to capitalized asset retirement costs in our consolidated statements of operations for the six months ended June 30, 2021 and 2020, was $1,971,000 and $1,995,000, respectively. Capitalized asset retirement costs were $39,370,000 (consisting of $23,584,000 of known environmental liabilities and $15,786,000 of reserves for future environmental liabilities) as of June 30, 2021, and $39,610,000 (consisting of $23,573,000 of known environmental liabilities and $16,037,000 of reserves for future environmental liabilities) as of December 31, 2020. We recorded impairment charges aggregating $1,500,000 and $1,446,000 for the six months ended June 30, 2021 and 2020, respectively, for capitalized asset retirement costs. Environmental exposures are difficult to assess and estimate for numerous reasons, including the amount of data available upon initial assessment of contamination, alternative treatment methods that may be applied, location of the property which subjects it to differing local laws and regulations and their interpretations, changes in costs associated with environmental remediation services and equipment, the availability of state UST remediation funds and the possibility of existing legal claims giving rise to allocation of responsibilities to others, as well as the time it takes to remediate contamination and receive regulatory approval. In developing our liability for estimated environmental remediation obligations on a property by property basis, we consider, among other things, laws and regulations, assessments of contamination and surrounding geology, quality of information available, currently available technologies for treatment, alternative methods of remediation and prior experience. Environmental accruals are based on estimates derived upon facts known to us at this time, which are subject to significant change as circumstances change, and as environmental contingencies become more clearly defined and reasonably estimable. Any changes to our estimates or our assumptions that form the basis of our estimates may result in our providing an accrual, or adjustments to the amounts recorded, for environmental remediation liabilities. In July 2012, we purchased a 10-year pollution legal liability insurance policy covering substantially all of our properties at that time for preexisting unknown environmental liabilities and new environmental events. The policy has a $50,000,000 aggregate limit and is subject to various self-insured retentions and other conditions and limitations. Our intention in purchasing this policy was to obtain protection predominantly for significant events. In addition to the environmental insurance policy purchased by the Company, we also took assignment of certain environmental insurance policies, and rights to reimbursement for claims made thereunder, from Marketing, by order of the U.S. Bankruptcy Court during Marketing’s bankruptcy proceedings. Under these assigned polices, we have received and expect to continue to receive reimbursement of certain remediation expenses for covered claims. In light of the uncertainties associated with environmental expenditure contingencies, we are unable to estimate ranges in excess of the amount accrued with any certainty; however, we believe that it is possible that the fair value of future actual net expenditures could be substantially higher than amounts currently recorded by us. Adjustments to accrued liabilities for environmental remediation obligations will be reflected in our consolidated financial statements as they become probable and a reasonable estimate of fair value can be made.
