Our operations are affected by extensive and changing international, national, state and local laws, regulations, treaties, conventions and standards in force in international waters, the jurisdictions in which our LNG vessels operate, and the country or countries in which such vessels are registered, including those governing the management and disposal of hazardous substances and wastes, the cleanup of oil spills and other contamination, air emissions, and water discharges and ballast and bilge water management. These regulations include, but are not limited to, the U.S. Oil Pollution Act of 1990, or OPA, requirements of the U.S. Coast Guard, or the USCG, and the U.S. Environmental Protection Agency, or EPA, the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA, the U.S. Clean Water Act, the U.S. Maritime Transportation Security Act of 2002, and regulations of the International Maritime Organization, or IMO, including the International Convention for the Safety of Life at Sea of 1974, or SOLAS, the International Convention for the Prevention of Pollution from Ships of 1973, or MARPOL, including the designation thereunder of Emission Control Areas, or ECAs, the International Convention on Civil Liability for Oil Pollution Damage of 1969, or CLC, and the International Convention on Load Lines of 1966. In particular, IMO's Marine Environmental Protection Committee ("MEPC") 73, amendments to Annex VI prohibiting the carriage of bunkers above 0.5% sulfur on ships took effect March 1, 2020 and may cause us to incur substantial costs. Compliance with these regulations could have a material adverse effect our business and financial results.
In addition, vessel classification societies and the requirements set forth in the IMO's International Management Code for the Safe Operation of Ships and for Pollution Prevention, or the ISM Code, also impose significant safety and other requirements on our vessels. In complying with current and future environmental requirements, vessel owners and operators may also incur significant additional costs in meeting new maintenance and inspection requirements, in developing contingency arrangements for potential spills and in obtaining insurance coverage. Government regulation of vessels, particularly in the areas of safety and environmental requirements, can be expected to become stricter in the future and require us to incur significant capital expenditures on our vessels to keep them in compliance, or even to recycle or sell certain vessels altogether.
Many of these requirements are designed to reduce the risk of oil spills and other pollution, and our compliance with these requirements can be costly. These requirements can also affect the resale value or useful lives of our vessels, require reductions in cargo capacity, ship modifications or operational changes or restrictions, lead to decreased availability of insurance coverage for environmental matters or result in the denial of access to certain jurisdictional waters or ports, or detention in certain ports.
Under local, national and foreign laws, as well as international treaties and conventions, we could incur material liabilities, including cleanup obligations, natural resource damages and third-party claims for personal injury or property damages, in the event that there is a release of petroleum or other hazardous substances from our vessels or otherwise in connection with our current or historic operations. We could also incur substantial penalties, fines and other civil or criminal sanctions, including in certain instances seizure or detention of our vessels, as a result of violations of or liabilities under environmental laws, regulations and other requirements. Environmental laws often impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault. For example, OPA affects all vessel owners shipping oil to, from or within the United States. Under OPA, owners, operators and bareboat charterers are jointly and severally strictly liable for the discharge of oil in U.S. waters, including the 200 nautical mile exclusive economic zone around the United States. Similarly, the CLC, which has been adopted by most countries outside of the United States, imposes liability for oil pollution in international waters. OPA expressly permits individual states to impose their own liability regimes with regard to hazardous materials and oil pollution incidents occurring within their boundaries, provided they accept, at a minimum, the levels of liability established under OPA. Coastal states in the United States have enacted pollution prevention liability and response laws, many providing for unlimited liability. Furthermore, the 2010 explosion of the drilling rig Deepwater Horizon, and the subsequent release of oil into the Gulf of Mexico, or other events, has resulted in increased, and may result in further, regulation of the shipping and offshore industries and modifications to statutory liability schemes, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. An oil spill could also result in significant liability, including fines, penalties, criminal liability and remediation costs for natural resource damages under other international and U.S. federal, state and local laws, as well as third-party damages, and could harm our reputation with current or potential charterers of our vessels. We are required to satisfy insurance and financial responsibility requirements for potential oil (including marine fuel) spills and other pollution incidents. Although we have arranged insurance to cover certain environmental risks, there can be no assurance that such insurance will be sufficient to cover all such risks or that any claims will not have a material adverse effect on our business, results of operations, cash flows and financial condition and available cash.
