We and our facilities and operations are subject to various federal, state and local environmental, health and safety laws, and regulations. These laws and regulations continue to evolve and are expected to increase in both number and complexity over time and govern not only the manner in which we conduct our operations, but also the products we sell. For example, international agreements and national, regional, and state legislation and regulatory measures that aim to limit or reduce greenhouse gas emissions or otherwise address climate change are currently in various stages of implementation. Additionally, in March 2022, the SEC proposed new climate-related disclosure rules, which if adopted as proposed, would require significant new climate-related disclosure in SEC filings, including certain climate-related metrics and greenhouse gas emissions data, and third-party attestation requirements. At this time, we cannot predict the costs of compliance with or any potential adverse impacts resulting from, these new rules if adopted as proposed, but compliance with such rules, when they are finalized, could require significant effort and divert management's attention and resources, which could adversely affect our operating results. There are inherent risks that increasingly restrictive environmental and other regulation could materially impact our results of operations or financial condition. Most of the costs of complying with existing laws and regulations pertaining to our operations and products are embedded in the normal costs of doing business. However, it is not possible to predict with certainty the amount of additional investments in new or existing technology or facilities, or the amounts of increased operating costs to be incurred in the future, to prevent, control, reduce or eliminate releases of hazardous materials or other pollutants into the environment; remediate and restore areas damaged by prior releases of hazardous materials; or comply with new or changed environmental laws or regulations. Although these costs may be significant to the results of operations, we do not presently expect them to have a material adverse effect on our liquidity or financial position. Accidental leaks and spills requiring cleanup may occur in the ordinary course of business. We may incur expenses for corrective actions or environmental investigations at various owned and previously owned facilities, leased or previously leased facilities, at third-party sites we manage, and at third-party-owned waste disposal sites used by us. An obligation may arise when operations are closed or sold or at non-company sites where company products have been handled or disposed of. Expenditures to fulfill these obligations may relate to facilities and sites where past operations followed practices and procedures that were considered acceptable at the time but may require investigative or remedial work or both to meet current or future standards.
Most of our fuel is transported by third-party carriers to our retail, dealer and fleet fueling sites. A portion of fuel is transported in our own trucks, instead of by third-party carriers, therefore, our operations are also subject to hazards and risks inherent in transporting motor fuel. These hazards and risks include, but are not limited to, fires, explosions, traffic accidents, spills, discharges and other releases, and cross-drops, any of which could result in distribution difficulties and disruptions, environmental pollution, governmentally-imposed fines or clean-up obligations, personal injury or wrongful death claims and other damage to our properties and the properties of others.
The transportation of motor fuels, as well as the associated storage of such fuels at locations including convenience stores, are subject to various federal, state and local environmental laws and regulations, including those relating to ownership and operation of storage tanks, the release or discharge of regulated materials into the air, water and soil, the generation, storage, handling, use, transportation and disposal of hazardous materials, the exposure of persons to regulated materials, and the health and safety of employees dedicated to such transportation and storage activities. These laws and regulations may impose numerous obligations and restrictions that are applicable to motor fuels transportation and storage and other related activities, including acquisition of, or applications for, permits, licenses, or other approvals before conducting regulated activities; restrictions on the quality and labeling of the motor fuels that may be sold; restrictions on the types, quantities and concentration of materials that may be released into the environment; required capital expenditures to comply with pollution control requirements; and imposition of substantial liabilities for pollution or non-compliance resulting from these activities. Numerous governmental authorities, such as the DOT and EPA, and analogous state agencies, have the power to monitor and enforce compliance with these laws and regulations and the permits, licenses and approvals issued under them, including fines, which can result in increased pollution control equipment costs or other actions. Failure to comply with these existing laws and regulations, or any newly adopted laws or regulations, may trigger administrative, civil or criminal enforcement measures, including the assessment of monetary penalties or other sanctions, the imposition of investigative, remedial or corrective action obligations, the imposition of additional compliance requirements on certain operations or the issuance of orders enjoining certain operations. Moreover, the trend in environmental regulation is for more restrictions and limitations on activities that may adversely affect the environment, which aligns with a growing trend in investor sentiment, and such regulation may result in increased costs of compliance.
Where releases of motor fuels or other substances or wastes have occurred, federal and state laws and regulations, and our lease agreements, require that contamination caused by such releases be assessed and remediated to meet applicable clean-up standards. Certain environmental laws impose strict, joint and several liability for costs required to clean-up and restore sites where motor fuels or other waste products have been disposed of or otherwise released. The costs associated with the investigation and remediation of contamination, as well as any associated third-party claims for damages or to impose corrective action obligations, could be substantial and could have a material adverse effect on us or our customers who transport motor fuels or own or operate convenience stores or other facilities where motor fuels are stored.
