The objective of this Overview and Background Section is to provide an overview of important environmental laws and regulations. It is intended to be nonauthoritative. The summary of legal matters contained in this Section represents an understanding of the legal requirements and practices at the time that these environmental laws were initially enacted. Any references to the various laws, rules, regulations established by others shall not be considered definitive interpretations of such laws, rules, and regulations for any purpose. Laws, rules and regulations may change over time and the standard Financial Accounting Standards Board (FASB) process will not update the Codification for such changes. The FASB assumes no responsibility for the accuracy of the legal guidance included here. Therefore, users must evaluate the current laws, rules, and regulations. ##### [410-30-05-3](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-3) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:7c384ba806054589636b1250546c9e7ed04d82800fa18b505f0195b81fd84ca0 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Although this Section focuses on both state and federal U. S. laws and regulations, environmental considerations are also important for foreign operations. Environmental laws and regulations in many countries are similar to U. S. laws. The legal and regulatory climates in other countries are evolving. Regardless of whether the host countries' environmental laws are as stringent as those in the United States, entities can often be held liable for environmental damages under a variety of nonenvironmental statutes and broad legal theories. ##### [410-30-05-4](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-4) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:5e9f0c49cf97894a1d859ac9ea4eacdace37a9ba57ef8ff373a937c2b2927e80 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

The first kind of environmental law, environmental remediation liability laws, includes individual statutes as well as response provisions in other statutes. The most important of these are the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and the Reauthorization Act of 1986, which together are referred to as Superfund, and the [corrective action](https://asc.understandingaccounting.org/glossary/c/#corrective-action "Related to the Resource Conservation and Recovery Act of 1976: action to remedy releases from hazardous waste management units, or any other sources of releases at or from a treatment, storage, or disposal facility.") provisions of the Resource Conservation and Recovery Act of 1976. Under Superfund's current broad liability provisions, the U.S. Environmental Protection Agency may order liable parties to remediate sites or use Superfund money to remediate them and then seek to recover its costs and additional damages. Similarly, under the corrective action provisions of the Resource Conservation and Recovery Act of 1976, the Environmental Protection Agency may order "facilities that treat, store, or dispose of hazardous waste" to clean up releases of [hazardous waste constituents](https://asc.understandingaccounting.org/glossary/h/#hazardous-waste-constituent "A constituent that caused the waste to be listed as a hazardous waste under the Resource Conservation and Recovery Act of 1976 40 CFR Part 261 Subpart D.") associated with past or ongoing practices. ##### [410-30-05-6](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-6) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:434f42370bbd3b2bb412abdadb337951b517f7b073d983c351db109d6f840b1b Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 in 1980 to facilitate the remediation of abandoned waste sites. The Comprehensive Environmental Response, Compensation, and Liability Act established a program to identify sites where hazardous substances have been or might be released into the environment; to ensure that they are remediated by responsible parties or the government; to compensate the United States, states, municipalities, and tribes for damages to [natural resources](https://asc.understandingaccounting.org/glossary/n/#natural-resources "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, natural resources are defined as land, fish, wildlife, biota, air, water, groundwater, drinking water supplies, and other such resources belonging to, managed or held in trust by, or otherwise controlled by the United States, state or local governments, foreign governments, or Indian tribes."); and to create a procedure for claims against responsible parties by parties who have cleaned up sites or spent money to restore natural resources. ##### [410-30-05-7](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-7) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:0cb3c860444aa2d0c24bc05e6b5264c5eba07a3e088773906fc3d5064296e901 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The Resource Conservation and Recovery Act provides comprehensive federal regulation of [hazardous wastes](https://asc.understandingaccounting.org/glossary/h/#hazardous-waste "Related to Resource Conservation and Recovery Act of 1976: a waste, or combination of wastes, that because of its quantity, concentration, toxicity, corrosiveness, mutagenicity or inflammability, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness or pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed. Technically, those wastes that are regulated under the Resource Conservation and Recovery Act of 1976 40 CFR Part 261 are considered to be hazardous wastes.") from point of generation to final [disposal](https://asc.understandingaccounting.org/glossary/d/#disposal "Related to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Resource Conservation and Recovery Act of 1976: under the Resource Conservation and Recovery Act of 1976, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including groundwaters. Similarly under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 with regard to hazardous substances."). All generators of hazardous waste, transporters of hazardous waste, and owners and operators of hazardous waste treatment, storage, or disposal facilities must comply with the applicable requirements of the statute. Many states have also enacted laws that are similar to the federal statutes. Furthermore, under certain federal statutes, such as the Resource Conservation and Recovery Act of 1976, states are allowed to promulgate regulations to implement federal programs as long as the state law is at least as stringent as the federal law. In most such cases, states are free to enact more stringent provisions. #### Laws Intended to Control or Prevent Pollution ##### [410-30-05-8](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-8) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:1ac574ef2d311bb05fbb01aa51c61ec7a0302b5c717bd025c7aaf1a1a545b30d Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Environmental laws of the second kind are intended to control or prevent pollution and are directed at identifying or regulating pollution sources or reducing emissions or discharges of pollutants. There are many statutes that regulate sources of pollution, including the pollution control provisions of the Resource Conservation and Recovery Act of 1976 (solid and hazardous wastes), the Clean Water Act (discharge of pollutants into the waters of the United States and to publicly owned treatment works), and the Clean Air Act (emission of pollutants into the atmosphere). Other examples are the Emergency Planning and Community Right-to-Know Act and the Pollution Prevention Act of 1990. ##### [410-30-05-9](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-9) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:11cd82c39f1a0909d6f6ff161e10bbba68d7229e9ddf227ba74f399c5e629903 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The pollution control provisions in Chapter 3 of the Resource Conservation and Recovery Act of 1976 provide for cradle-to-grave management standards for hazardous wastes. Section 7003 of the Resource Conservation and Recovery Act of 1976 also authorizes the Environmental Protection Agency to conduct [removal actions](https://asc.understandingaccounting.org/glossary/r/#removal-action "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, generally short-term actions taken to respond promptly to an urgent need. The cleanup or removal of released hazardous substances from the environment; actions in response to the threat of release; actions that may be necessary to monitor, assess, and evaluate the release or threat; disposal of removed material; or other actions needed to prevent, minimize, or mitigate damage to public health or welfare or to the environment. Removal also includes, without being limited to, security fencing or other measures to limit access; provision of alternative water supplies; temporary evacuation and housing of threatened individuals not otherwise provided for; and any emergency assistance provided under the Disaster Relief Act."), seek affirmative injunctive relief, and maintain cost-recovery actions where an imminent and substantial endangerment to the public health or welfare or to the environment is determined to exist. Much like under Superfund, one who has contributed to the disposal of waste that is causing an imminent and substantial endangerment can be required to perform or pay for associated remediation under section 7003. The Resource Conservation and Recovery Act of 1976 also requires the Environmental Protection Agency to regulate underground storage tanks. Most states have enacted their own underground storage tank regulations as well. ##### [410-30-05-10](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-10) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:bed109fd3a214d3d8a3d57e7f55abf5cb2ffbbc454a83bdd81378a980a7b6ef2 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The Clean Air Act provides comprehensive federal regulation of all sources of air pollution. Amendments to the Clean Air Act in the 1990s are designed to address issues such as acid rain, urban air pollution, toxic air pollutants, and ozone-depleting chemicals. The major provisions of the Clean Air Act amendments require emissions reduction in the electric utility industry, operating permits for existing facilities, an expansion of the air toxics program to regulate a large number of toxic air pollutants, and new source categories (including smaller sources, such as dry cleaners). ##### [410-30-05-11](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-11) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:8fa167554f4511e00dedf8f3f49e788da770a2e3dbe665e4367df1a718bcff7c Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The Clean Water Act provides comprehensive federal regulation of all sources of water pollution. The act authorizes cleanup, injunctive, and cost-recovery actions where an imminent hazard is caused by pollution. It also prohibits the discharge of oil and other hazardous substances to the navigable waters of the United States, imposes a criminal penalty for failure to notify the appropriate entity of such discharges, and provides for citizen suits. Most states have assumed enforcement of the Act within their borders through state regulations that correspond to the federal regulations related to the control or prevention of pollution of water. #### Other Federal Statutes ##### [410-30-05-12](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-12) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:fe4a6d3b50a2ffaf4a93500e53ae03ff0608b650bb550d003a46dd6425bb2aa4 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. There are a variety of other statutes that relate to environmental matters. Two of the more significant statutes are the Emergency Planning and Community Right-to-Know Act and the Toxic Substances Control Act. ##### [410-30-05-13](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-13) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:57afd5aaee9f5307e69f165aa3b06adbe28a808f04c81e2cadcac81a16aa81d0 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The Emergency Planning and Community Right-to-Know Act requires facilities that have certain quantities of extremely hazardous substances to notify their state emergency response commission that they are subject to the emergency planning requirements of the Superfund Amendments and Reauthorization Act of 1986. They must also report releases to the local emergency planning committee. In addition, facilities that store chemicals over specified threshold amounts must submit material safety data sheets, or their equivalent, to the appropriate local emergency planning committee, the state emergency response commission, and the fire department with jurisdiction over the facility. ##### [410-30-05-14](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-14) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:29ee61785e3b775839ba22b267a1be97d2a1f0742661400a4c7f19441b8f61af Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The Toxic Substances Control Act regulates the manufacture, processing, and distribution in commerce of chemical substances and mixtures capable of adversely affecting health or the environment. The Toxic Substances Control Act may require testing and may impose use restrictions, along with requirements for the reporting and retention of information on the risks of Toxic Substances Control Act- regulated substances.

Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, a hazardous substance is any element, compound, mixture, solution, or substance that, when released to the environment, may present substantial danger to the public health or welfare or to the environment. It also includes the following: Specifically designated substances Toxic pollutants under the Federal Water Pollution Control Act Hazardous wastes having the characteristics identified under or listed pursuant to the Resource Conservation and Recovery Act of 1976 (excluding any waste suspended from regulation under the Solid Waste Disposal Act by Congress) Hazardous air pollutants under the Clean Air Act Any imminently hazardous chemical substance or mixture for which the government has taken action under section 7 of the Toxic Substances Control Act.

The courts have interpreted the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 to impose [strict liability](https://asc.understandingaccounting.org/glossary/s/#strict-liability "Liability imposed without regard to the liable party's fault."). Thus, a waste generator that disposed of its waste at approved facilities, in accordance with all then-current requirements, having exercised "due care," would nevertheless be liable. Further, a waste generator that is responsible for a small percentage of the total amount of waste at a site may be held liable for the entire cost of remediating the site. ##### [410-30-05-18](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-18) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:e8346ee2dc75b8676b2e7f6168bd9161cfaf4cf65a578be5a6c9dd4ad055ae53 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Also noteworthy is that wastes need not be hazardous wastes for there to be environmental remediation liability. If the waste generator "arranged for disposal" of wastes containing hazardous substances (at any concentration level and regardless of whether the substances were defined as, or known to be, hazardous at the time of disposal), and a "release" of hazardous substances has or could occur, the waste generator could be subject to environmental remediation liability. ##### [410-30-05-19](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-19) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:f78f72d13fcf3d4dde76fcaad8014989fb0b163366edfa5a59abd6336c687660 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Hazardous substance is a much broader term than hazardous waste. It includes any substance identified by the Environmental Protection Agency by regulation, pursuant to a number of federal statutes. Covered, for example, are substances considered to be toxic pollutants under the Clean Water Act or hazardous air pollutants under the Clean Air Act. The various lists of hazardous substances identified by the Environmental Protection Agency contain more than one thousand chemicals and chemical compounds. ##### [410-30-05-20](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-20) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:abe4af67646023c009d899129275b24b4e6961899a1f2c6d03f1fedb68d008a4 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

This scheme of liability means that any responsible party can potentially be liable for the entire cost of remediating a site, notwithstanding that the party is responsible for only a small amount of the total hazardous substances or waste at the site and did nothing improper."). If a potentially responsible party can prove, however, that the harm is divisible and there is a reasonable basis for apportionment of costs, the potentially responsible party may ultimately be responsible only for its portion of the costs. ##### [410-30-05-22](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-22) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:4cb822cf94a1e3bc7a0a6b49e15877d5155afd38fd6476b89f2e589294df3fbc Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. In order to mitigate the potentially harsh effects of the strict, joint and several, and retroactive liability scheme, however, Superfund does permit responsible parties to sue other responsible parties to make them contribute to the cost of the remediation or to recover money spent on remediation. #### Costs Associated with Remediation ##### [410-30-05-23](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-23) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:b7e9ee37dbb125bd54aaafc4cf90af321accf167aafab17df2afd84399e5acff Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Also refers to corrective action under the Resource Conservation and Recovery Act of 1976.")), enforcement costs (for example, legal), government oversight costs, and natural resource damages. Though the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 does not provide for personal injury or property damage suits, suits for injury to health or property (referred to as toxic torts) may also be brought by third parties under various legal theories. There is a growing specter of liability for natural resource damages under the Superfund laws. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 authorizes the recovery of damages for injury to, destruction of, or loss of natural resources, including reasonable costs for assessing such injury resulting from a release of a hazardous substance. Natural resource damage claims include actual restoration costs and lost use values and may in the future include nonuse values, such as the intrinsic public value of protecting or restoring resources that may not be used but are valuable for their mere existence. ##### [410-30-05-24](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-24) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:8a17dd9f97cbfaf5a488931e3c8d781e122580c76d017cfe9291f04c672b6c0a Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Additional costs can include a remedial investigation and a feasibility study that together generally take a minimum of two years to complete and, depending on factors such as the types of hazardous substances, soil formations, and number of parties involved, may take more than five years. The Environmental Protection Agency oversees the progress of the remedial investigation and feasibility study, and completion is sometimes performed in stages. After Superfund site remedial action is completed, activities must be conducted at the site to ensure that the remedy is effective and operating properly. For example, after a system to pump and treat groundwater is constructed (remedial action), the system must be operated and maintained. In addition, the Environmental Protection Agency may require postremediation monitoring. These operation and maintenance activities may continue for 30 years or longer. #### Environmental Loss Contingencies ##### [410-30-05-25](https://asc.understandingaccounting.org/asc/410/30/#410-30-05-25) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:23.089Z to 2026-09-10T00:21:23.089Z Record version: sha256:4037a063de2affc640419c1397058c9eb1f2da645d46a38f783b65cdb6a290ee Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

The guidance in this Subtopic does not apply to the following transactions and activities: 1. a Environmental contamination incurred in the normal operation of a long-lived asset (see Subtopic 410-20 for guidance that will apply if the entity is legally obligated to treat the contamination). Paragraph [410-20-15-3(b)](https://asc.understandingaccounting.org/asc/410/20/#410-20-15-3) explains that the obligation to clean up the spillage resulting from the normal operation of the fuel storage facility is within the scope of Subtopic 410-20.

Paragraph [450-20-25-2](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-2) requires the accrual of a liability if both of the following conditions are met: 1. a Information available before the financial statements are issued or are available to be issued (as discussed in Section 855-10-25) indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements. 2. b The amount of the loss can be reasonably estimated. ##### [410-30-25-2](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-2) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:6faf488d076e49b0105189bd4ec8e8c53c72e0ac6df154331fb3e9a4aef2803f Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. An entity's environmental remediation obligation that results in a liability generally does not become determinable as a distinct event, nor is the amount of the liability generally fixed and determinable at a specific point in time. Rather, the existence of a liability for environmental remediation costs becomes determinable and the amount of the liability becomes estimable over a continuum of events and activities that help to frame, define, and verify the liability.

In the context of environmental remediation liabilities, the probability criterion in paragraph [450-20-25-2](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-2) consists of two elements; the criterion is met if both of the following elements are met on or before the date the financial statements are issued or are available to be issued (as discussed in Section 855-10-25): 1. a Litigation has commenced or a claim or an assessment has been asserted, or, based on available information, commencement of litigation or assertion of a claim or an assessment is probable. In other words, it has been asserted (or it is probable that it will be asserted) that the entity is responsible for participating in a remediation process because of a past event. 2. b Based on available information, it is probable that the outcome of such litigation, claim, or assessment will be unfavorable.

Given the legal framework within which most environmental remediation liabilities arise, there is a presumption that the outcome of such litigation, claim, or assessment will be unfavorable if both of the following conditions exist: 1. a Litigation has commenced or a claim or an assessment has been asserted, or commencement of litigation or assertion of a claim or assessment is probable. 2. b The reporting entity is associated with the site—that is, it in fact arranged for the [disposal](https://asc.understandingaccounting.org/glossary/d/#disposal "Related to the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Resource Conservation and Recovery Act of 1976: under the Resource Conservation and Recovery Act of 1976, the discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid waste or hazardous waste into or on any land or water so that such solid waste or hazardous waste or any constituent thereof may enter the environment or be emitted into the air or discharged into any waters, including groundwaters.

Estimating environmental remediation liabilities involves an array of issues at any point in time. In the early stages of the process, cost estimates can be difficult to derive because of uncertainties about a variety of factors. For this reason, estimates developed in the early stages of remediation can vary significantly; in many cases, early estimates later require significant revision. The following are some of the factors that are integral to developing cost estimates: 1. a The extent and types of hazardous substances at a site 2. b The range of technologies that can be used for remediation 3. c Evolving standards of what constitutes acceptable remediation 4. d The number and financial condition of other potentially responsible parties and the extent of their responsibility for the remediation (that is, the extent and types of hazardous substances they contributed to the site). ##### [410-30-25-8](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-8) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:da5d34de698e83621f9350b1491b8be328f82d12cbf1d7f50e7d307758914c88 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Section 450-20-55 concludes that the criterion for recognition of a loss contingency in paragraph [450-20-25-2(b)](https://asc.understandingaccounting.org/asc/450/20/#450-20-25-2) is met when a range of loss can be reasonably estimated. ##### [410-30-25-9](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-9) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:2a69d1b29cd72031776db1f1e446f5e313be730307431cb66c9b36ec77281d46 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. An estimate of the range of an environmental remediation liability typically is derived by combining estimates of various components of the liability (such as the costs of performing particular tasks, or amounts allocable to other potentially responsible parties but that will not be paid by those other potentially responsible parties), which are themselves likely to be ranges. For some of those component ranges, there may be amounts that appear to be better estimates than any other amount within the range; for other component ranges, there may be no such best estimates. Accordingly, the overall liability that is recorded may be based on amounts representing the lower end of a range of costs for some components of the liability and best estimates within ranges of costs of other components of the liability. ##### [410-30-25-10](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-10) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:caafe017b6bd16f24dfbbe9d85c4a0f2801a03760aab9f50ce45eed40560b2bc Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. At the early stages of the remediation process, particular components of the overall liability may not be reasonably estimable. This fact should not preclude the recognition of a liability. Rather, the components of the liability that can be reasonably estimated should be viewed as a surrogate for the minimum in the range of the overall liability. ##### [410-30-25-11](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-11) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:86e8e21f79cb60810be7c1c918c07227dec762365b9740defff27e9806f54b7f Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. For example, a sole potentially responsible party that has confirmed that it sent waste to a Superfund site and agrees to perform a remedial investigation and feasibility study may know that it will incur costs related to the [remedial investigation-feasibility study](https://asc.understandingaccounting.org/glossary/r/#remedial-investigation-feasibility-study "Extensive technical studies conducted by the government or by the potentially responsible parties to investigate the scope of site impacts and determine the remedial alternatives that, consistent with the National Contingency Plan, may be implemented at a Superfund site.

Remedial investigation-feasibility studies conducted by potentially responsible parties usually do recommend and technically support a remedial alternative.

The potentially responsible party, although aware that the total costs associated with the site will be greater than the cost of the remedial investigation-feasibility study, may be unable to reasonably estimate the overall liability because of existing uncertainties, for example, regarding the kinds and quantities of hazardous substances present at the site and the technologies available to remediate the site. This lack of ability to quantify the total costs of the remediation effort, however, shall not preclude recognition of the estimated cost of the remedial investigation-feasibility study.

Uncertainties relating to the entity's share of an environmental remediation liability shall not preclude the entity from recognizing its best estimate of its share of the liability or, if no best estimate can be made, the minimum estimate of its share of the liability, if the liability is probable and the total remediation liability associated with the site is reasonably estimable within a range (see paragraphs [410-30-30-1 through 30-7](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-1) ). ##### [410-30-25-13](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-13) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:7fb57355be1ccc789f593b962a30f48d04fbe1f94b74ec023331c83e58dbeb3d Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Uncertainties are pervasive in the measurement of environmental remediation liabilities, and reporting entities are required to recognize their best estimate at the particular point in time (or, if no best estimate can be made, the minimum estimate) of their share of the liability and to refine their estimate as events in the remediation process occur. #### Benchmarks ##### [410-30-25-14](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-14) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:fe3337e533e5cb73366de90e5ff4f2fab991b845461ab26f0a08c317e5d06f42 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

The following are recognition benchmarks for a Superfund remediation liability; analogous stages of the Resource Conservation and Recovery Act corrective-action process are also indicated. At a minimum, the estimate of a Superfund (or Resource Conservation and Recovery Act) remediation liability should be evaluated as each of these benchmarks occurs. 1. a Identification and verification of an entity as a potentially responsible party. The Resource Conservation and Recovery Act analogue is subjection to facility permit requirements. Receipt of notification or otherwise becoming aware that an entity may be a potentially responsible party compels the entity to action. The entity must examine its records to determine whether it is associated with the site. If, based on a review and evaluation of its records and all other available information, the entity determines that it is associated with the site, it is probable that a liability has been incurred. If all or a portion of the liability is reasonably estimable, the liability shall be recognized. In some cases, an entity will be able to reasonably estimate a range of its liability very early in the process because the site situation is common or similar to situations at other sites with which the entity has been associated (for example, the remediation involves only the removal of underground storage tanks in accordance with the underground storage tank program). In such cases, the criteria for recognition would be met and the liability shall be recognized. In other cases, however, the entity may have insufficient information to reasonably estimate the minimum amount in the range of its liability. In these cases, the criteria for recognition would not be met at this time. 2. b Receipt of [unilateral administrative order](https://asc.understandingaccounting.org/glossary/u/#unilateral-administrative-order "Order issued unilaterally by the Environmental Protection Agency under section 106(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 to potentially responsible parties, or to nonpotentially responsible parties such as adjacent landowners, requiring them to take a response action. Unilateral administrative orders contain findings of fact and conclusions of law, and they specify the work to be performed and the Environmental Protection Agency's right to take over the work in the event of noncompliance, inadequate performance, or an emergency. A unilateral administrative order does not allocate conduct required by the order between individual potentially responsible parties; however, the Environmental Protection Agency may issue carve-out orders requiring individual potentially responsible parties to perform specific actions. Also referred to as a section 106 order."). The Resource Conservation and Recovery Act analogue is, generally, interim corrective measures. An entity may receive a unilateral administrative order compelling it to take a response action at a site or risk penalties of up to four times the cost of the response action. Such response actions may be relatively limited actions, such as the performance of a remedial investigation and feasibility study or performance of a [removal action](https://asc.understandingaccounting.org/glossary/r/#removal-action "Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, generally short-term actions taken to respond promptly to an urgent need. The cleanup or removal of released hazardous substances from the environment; actions in response to the threat of release; actions that may be necessary to monitor, assess, and evaluate the release or threat; disposal of removed material; or other actions needed to prevent, minimize, or mitigate damage to public health or welfare or to the environment. Removal also includes, without being limited to, security fencing or other measures to limit access; provision of alternative water supplies; temporary evacuation and housing of threatened individuals not otherwise provided for; and any emergency assistance provided under the Disaster Relief Act."), or they may be broad actions such as remediating a site. Under section 106 of Superfund, the Environmental Protection Agency must find that an "imminent and substantial endangerment" exists at the site before such an order may be issued. No preenforcement review by a court is authorized under Superfund if an entity elects to challenge a unilateral administrative order. The ability to estimate costs resulting from unilateral administrative orders varies with factors such as site complexity and the nature and extent of the work to be performed. The benchmarks that follow should be considered in evaluating the ability to estimate such costs insofar as the actions required by the unilateral administrative order involve these benchmarks. The cost of performing the requisite work generally is estimable within a range, and recognition of an environmental remediation liability for costs of removal actions generally should not be delayed beyond this point. 3. c Participation, as a potentially responsible party, in the remedial investigation-feasibility study. The Resource Conservation and Recovery Act analogue is Resource Conservation and Recovery Act facility investigation. At this stage, the entity and possibly others have been identified as potentially responsible parties and have agreed to pay the costs of a study that will investigate the extent of the environmental impact of the [release](https://asc.understandingaccounting.org/glossary/r/#release "Related to Superfund: any spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment. Includes the abandonment or discarding of barrels, containers, and other closed receptacles containing any hazardous substance, pollutant, or contaminant. The law provides for several exclusions. Release also means the substantial threat of release.") or threatened release of hazardous substances and identify site-remediation alternatives. Further, the total cost of the remedial investigation-feasibility study generally is estimable within a reasonable range. In addition, the identification of other potentially responsible parties and their agreement to participate in funding the remedial investigation-feasibility study typically provides a reasonable basis for determining the entity's allocable share of the cost of the remedial investigation-feasibility study. At this stage, additional information may be available regarding the extent of environmental impact and possible remediation alternatives. This additional information, however, may or may not be sufficient to provide a basis for reasonable estimation of the total remediation liability. At a minimum, the entity should recognize its share of the estimated total cost of the remedial investigation-feasibility study. As the remedial investigation-feasibility study proceeds, the entity's estimate of its share of the total cost of the remedial investigation-feasibility study can be refined. Further, additional information may become available based on which the entity can refine its estimates of other components of the liability or begin to estimate other components. For example, an entity may be able to estimate the extent of environmental impact at a site and to identify existing alternative remediation technologies. An entity may also be able to identify better the extent of its involvement at the site relative to other potentially responsible parties; the universe of potentially responsible parties may be identified; negotiations among potentially responsible parties and with federal and state Environmental Protection Agency representatives may occur; and information may be obtained that materially affects the agreed-upon method of remediation. 4. d Completion of feasibility study. The Resource Conservation and Recovery Act analogue is corrective measures study. At substantial completion of the feasibility study, both a minimum remediation liability and the entity's allocated share generally will be reasonably estimable. The feasibility study should be considered substantially complete no later than the point at which the potentially responsible parties recommend a proposed course of action to the Environmental Protection Agency. If the entity had not previously concluded that it could reasonably estimate the remediation liability (the best estimate or, if no amount within an estimated range of loss was a better estimate than any other amount in the range, the minimum amount in the range), recognition should not be delayed beyond this point, even if uncertainties, for example, about allocations to individual potentially responsible parties and potential recoveries from third parties, remain. 5. e Issuance of record of decision. The Resource Conservation and Recovery Act analogue is approval of corrective measures study. At this point, the Environmental Protection Agency has issued its determination specifying a preferred remedy. Normally, the entity and other potentially responsible parties have begun, or perhaps completed, negotiations, litigation (see paragraphs [410-30-35-8 through 35-11](https://asc.understandingaccounting.org/asc/410/30/#410-30-35-8) ), or both for their allocated share of the remediation liability. Accordingly, the entity's estimate normally can be refined based on the specified preferred remedy and a preliminary allocation of the total remediation costs. 6. f Remedial design through operation and maintenance, including postremediation monitoring. The Resource Conservation and Recovery Act analogue is corrective measures implementation. During the design phase of the remediation, engineers develop a better sense of the work to be done and are able to provide more precise estimates of the total remediation cost. Further information likely will become available at various points until the site is delisted, subject only to postremediation monitoring. The entity should continue to refine and recognize its best estimate of its final obligation as this additional information becomes available. #### Criteria to Capitalize Environmental Treatment Costs ##### [410-30-25-16](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-16) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:8731ac1f972ba1b809d6e70d648d67a8cde59e1ce900d9dbaf556d6da705f10d Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

For purposes of this criterion, the condition of that property after the costs are incurred must be improved as compared with the condition of that property when originally constructed or acquired, if later. 2. b The costs mitigate or prevent environmental contamination that has yet to occur and that otherwise may result from future operations or activities. In addition, the costs improve the property compared with its condition when constructed or acquired, if later. 3. c The costs are incurred in preparing for sale that property currently held for sale. ##### [410-30-25-19](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-19) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:562c0203e5cc2cf3150b422389dee1bfba61f794762168be6039d6daead08222 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. This Subtopic requires that tangible assets acquired to clean a particular spill not be charged to expense immediately. Rather, to the extent that those tangible assets have future uses, they may be capitalized. Example 5 (see paragraph [410-30-55-18](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-18)) illustrates this guidance. ##### [410-30-25-20](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-20) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:33.044Z to 2026-09-10T00:21:33.044Z Record version: sha256:3e1f8aa56bd73c9a8dfb929c2c4f7989be256b8023e981c4349331b8469dc771 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

At the early stages of the remediation process, environmental remediation liabilities are not easily quantified, due in part to their uncertainties. As a practical matter, the range of an estimated remediation liability will be defined and refined as events in the remediation process occur. The environmental remediation liability recorded by an entity should be based on that entity's estimate of its allocable share of the joint and several remediation liability. The estimation of an entity's allocable share of the joint and several remediation liability (see paragraph [410-30-55-4](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-4)) for a site requires an entity to do all of the following: 1. a Identify the [potentially responsible parties](https://asc.understandingaccounting.org/glossary/p/#potentially-responsible-party "Any individual, legal entity, or government—including owners, operators, transporters, or generators—potentially responsible for, or contributing to, the environmental impacts at a Superfund site. The Environmental Protection Agency has the authority to require potentially responsible parties, through administrative and legal actions, to remediate such sites. At early stages of the remediation process, the list of potentially responsible parties may be limited to a handful of entities that either were significant contributors of waste to the site or were easy to identify, for example, because of their proximity to the site or because of labeled material found at the site. As further investigation of the site occurs and as remediation activities take place, additional potentially responsible parties may be identified. Once identified, the additional potentially responsible parties would be reclassified from this category to either the participating potentially responsible party or recalcitrant potentially responsible party category. The total number of parties in this category and their aggregate allocable share of the remediation liability varies by site and cannot be reliably determined before the specific identification of individual potentially responsible parties. For example, some ultimately may be dropped from the potentially responsible party list because no substantive evidence is found to link them to the site. For others, substantive evidence eventually may be found that points to their liability. The presentation of that evidence to the entity would result in a reclassification of the party from this category of potentially responsible parties (sometimes referred to as hiding in the weeds) to either the participating potentially responsible party or recalcitrant potentially responsible party category.") for the site 2. b Assess the likelihood that other potentially responsible parties will pay their full allocable share of the joint and several remediation liability 3. c Determine the percentage of the liability that will be allocated to the entity. ##### [410-30-30-2](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-2) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:36.393Z to 2026-09-10T00:21:36.393Z Record version: sha256:4e6ba1929d92a11a4718b5f2d289268d169507a60881b9dc6b8498e19679fe1e Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. For purposes of estimating an entity's allocable share of the joint and several remediation liability for a site, those parties that are potentially responsible for paying the remediation liability belong to one of the following five potentially responsible party categories: 1. a [Participating potentially responsible parties](https://asc.understandingaccounting.org/glossary/p/#participating-potentially-responsible-party "A party to a Superfund site that has acknowledged potential involvement with respect to the site. Active potentially responsible parties may participate in the various administrative, negotiation, monitoring, and remediation activities related to the site. Others may adopt a passive stance and simply monitor the activities and decisions of the more involved potentially responsible parties. This passive stance could result from a variety of factors such as the entity's lack of experience, limited internal resources, or relative involvement at a site. This category of potentially responsible parties (both active and passive) is also referred to as players.") 2. b [Recalcitrant potentially responsible parties](https://asc.understandingaccounting.org/glossary/r/#recalcitrant-potentially-responsible-party "A party whose liability with respect to a Superfund site is substantiated by evidence, but that refuses to acknowledge potential involvement with respect to the site. Recalcitrant potentially responsible parties adopt a recalcitrant attitude toward the entire remediation effort even though evidence exists that points to their involvement at a site. Some may adopt this attitude out of ignorance of the law; others may do so in the hope that they will be considered a nuisance and therefore ignored. Typically, parties in this category must be sued in order to collect their allocable share of the remediation liability; however, it may be that it is not economical to bring such suits because the parties' assets are limited. This category of potentially responsible parties is also referred to as nonparticipating potentially responsible parties.") 3. c [Unproven potentially responsible parties](https://asc.understandingaccounting.org/glossary/u/#unproven-potentially-responsible-party "A party that has been identified as a potentially responsible party for a Superfund site by the U.S. Environmental Protection Agency or by an analogous state agency, but that does not acknowledge potential involvement with respect to the site because no evidence has been presented linking the party to the site. Also referred to as a hiding-in-the-weeds potentially responsible party.") 4. d [Unknown potentially responsible parties](https://asc.understandingaccounting.org/glossary/u/#unknown-potentially-responsible-party "A party that has liability with respect to a Superfund site, but that has not yet been identified as a potentially responsible party by the Environmental Protection Agency or by an analogous state agency.") 5. e [Orphan share potentially responsible parties](https://asc.understandingaccounting.org/glossary/o/#orphan-share-potentially-responsible-party "An identified potentially responsible party that cannot be located or that is insolvent. Some of these parties may be identified by the Environmental Protection Agency; others may be identified as the site is investigated or as the remediation is performed.

An entity shall determine its allocable share of the joint and several remediation liability for a site based on its estimate of the allocation method and percentage that ultimately will be used for the entire remediation effort. The primary sources for this estimate shall be the allocation method and percentages that: 1. a The potentially responsible parties have agreed to (whether that agreement applies to the entire remediation effort or to the costs incurred in the current phase of the remediation process) 2. b Have been assigned by a consultant 3. c Have been determined by the Environmental Protection Agency. ##### [410-30-30-6](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-6) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:36.393Z to 2026-09-10T00:21:36.393Z Record version: sha256:f5fdfef760b3a702451fcaf36d1363eeea9125cd18aba38c3e31287d7fccd476 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. If the entity's estimate of the ultimate allocation method and percentage differs significantly from the method or percentage from these primary sources, the entity's estimate should be based on objective, verifiable information. Examples of objective, verifiable information include all of the following: 1. a Existing data about the kinds and quantities of waste at the site 2. b Experience with allocation approaches in comparable situations 3. c Reports of environmental specialists (internal or external) 4. d Internal data refuting Environmental Protection Agency allegations about the entity's contribution of waste (kind, volume, and so forth) to the site. ##### [410-30-30-7](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-7) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:36.393Z to 2026-09-10T00:21:36.393Z Record version: sha256:8ce8ba9f7aee77568233f59916738fb3c70ebe1853a5610c52c5425dad62a2c8 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. An entity should assess the likelihood that each potentially responsible party will pay its allocable share of the joint and several remediation liability. That assessment should be based primarily on the financial condition of the participating potentially responsible party. This assessment requires the entity to gain an understanding of the financial condition of the other participating potentially responsible parties and to update and monitor this information as the remediation progresses.

Although this approach is sometimes referred to as considering inflation, it does not simply rely on an inflation index (cost estimates submitted to the Environmental Protection Agency usually include a prescribed inflation factor) and should take into account factors such as productivity improvements due to learning from experience with similar sites and similar remedial action plans. In situations in which it is not practicable to estimate inflation and such other factors because of uncertainty about the timing of expenditures, a current-cost estimate would be the minimum in the range of the liability to be recorded until such time as these cost effects can be reasonably estimated. ##### [410-30-30-18](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-18) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:36.393Z to 2026-09-10T00:21:36.393Z Record version: sha256:5c51ef040eef406f098b240daeb72911ba1a9772d2c8c8adca3318704065061a Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Additional complexities arise if other potentially responsible parties are involved in an identified site. The costs associated with remediation of a site ultimately will be assigned and allocated among the various potentially responsible parties. The final allocation of costs may not be known, however, until the remediation effort is substantially complete, and it may or may not be based on an entity's relative direct responsibility at a site. An entity's final obligation depends, among other things, on the willingness of the entity and other potentially responsible parties to negotiate a cost allocation, the results of the entity's negotiation efforts, and the ability of other potentially responsible parties associated with the particular site to fund the remediation effort. ##### [410-30-35-3](https://asc.understandingaccounting.org/asc/410/30/#410-30-35-3) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:38.042Z to 2026-09-10T00:21:38.042Z Record version: sha256:2e69df5fdcedb9a3fb85e49387fc2c96846a1dc2af041740b32f215de0bef56e Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Furthermore, it is particularly difficult to substantiate the classification of environmental remediation costs as a component of nonoperating expenses. Because the events underlying the incurrence of the obligation relate to an entity's operations, remediation costs shall be charged against operations. Although charging the costs of remediating past environmental impacts against current operations may appear debatable because of the time between the contribution or transportation of waste materials containing hazardous substances to a site and the subsequent incurrence of remediation costs, environmental remediation-related expenses have become a regular cost of conducting economic activity. Accordingly, environmental remediation-related expenses shall be reported as a component of operating income in income statements that classify items as operating or nonoperating. Credits arising from recoveries of environmental losses from other parties shall be reflected in the same income statement line. Any earnings on assets that are reflected on the entity's financial statements and are earmarked for funding its environmental liabilities shall be reported as investment income. ##### [410-30-45-5](https://asc.understandingaccounting.org/asc/410/30/#410-30-45-5) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:40.209Z to 2026-09-10T00:21:40.209Z Record version: sha256:7e963ce5612a32f0144f70e1414b2ac45efb1605a9d7fb8b811947963b626d86 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Because environmental remediation costs have become increasingly significant, and because the accounting for many environmental loss contingencies often involves subjective judgments, disclosure of accrual benchmarks for remediation obligations is useful to further users' understanding of the entity's financial statements. Accordingly, entities are encouraged, but not required, to disclose the event, situation, or set of circumstances that generally triggers recognition of loss contingencies that arise out of the entity's environmental remediation-related obligations (for example, during or upon completion of the feasibility study). Also, entities are encouraged to disclose their policy concerning the timing of recognition of recoveries.

Uncertainties associated with environmental remediation loss contingencies are pervasive, and they often result in wide ranges of reasonably possible losses with respect to such contingencies. Further, resolution of the uncertainties and the cash-flow effects of the loss contingencies often occur over a span of many years. Accordingly, this Subtopic encourages, but does not require, additional specific disclosures with respect to environmental remediation loss contingencies that would be useful to further users' understanding of the entity's financial statements. ##### [410-30-50-10](https://asc.understandingaccounting.org/asc/410/30/#410-30-50-10) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:41.845Z to 2026-09-10T00:21:41.845Z Record version: sha256:562eb4086c62a6a2f4de725716b2739a57080a32a0bd1414f60848d81439fcee Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

There are numerous ways to allocate liabilities among potentially responsible parties. The four principal factors considered in a typical allocation process are the following: 1. a Elements of fair share. Examples are the amount of waste based on volume; the amount of waste based on mass, type of waste, toxicity of waste; the length of time the site was used. 2. b Classification of potentially responsible party. Examples are site owner, site operator, transporter of waste, generator of waste. 3. c Limitations on payments. This characteristic includes any statutory or regulatory limitations on contributions that may be applicable to a potentially responsible party. For example, in the reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act, it has been proposed that the statute limit the contribution of a municipality to 10 percent of the total remediation liability, irrespective of the municipality's allocable share. 4. d Degree of care. This refers to the degree of care exercised in selecting the site or in selecting a transporter. ##### [410-30-55-5](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-5) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:e0dcb60eb5679c02da3eedd23fb3f09f1e249d769f4ada68bbcb3dbd014176ab Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Potentially responsible parties may reach an agreement among themselves as to the allocation method and percentages to be used, they may hire an allocation consultant whose conclusions may or may not be binding, or they may request a nonbinding allocation of responsibility from the Environmental Protection Agency. The allocation method or percentages used may change as the remediation project moves forward. An agreement to reallocate the preliminarily allocated liability at the end of the remediation project may exist, or the allocation percentages may be adjusted during the project to reflect prior allocations that subsequently are agreed to have been inequitable. This implementation guidance illustrates paragraph [410-30-30-1](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-1). ##### [410-30-55-6](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-6) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:fa29e7177481c9dd217c82c9370a062234c300a26fc8b93905b7f66a6d50fb2a Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. This implementation guidance addresses the criterion in paragraph [410-30-30-19(b)](https://asc.understandingaccounting.org/asc/410/30/#410-30-30-19) involving the dependency of the timing of the recovery on the timing of the payment of the liability. That criterion would usually be met, for example, if an insurance entity agrees, in accordance with the terms of an insurance contract, to reimburse the reporting entity for all or a percentage of the remediation costs incurred by the reporting entity as the reporting entity expends money to satisfy its obligation. That criterion likely would not be met, for example, in a lump-sum buyout by an insurance entity of contested coverage. #### Illustrations ##### [410-30-55-7](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-7) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:67426dd7173d0c55aaca8ef7bcaff6f6ec7dac5d9f4ef38e8a896f501c97325c Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Ace Oil Company is a distributor of heating oil with four storage and distribution facilities located in Anystate. Federal, state, and local laws and regulations govern the operation of the entity's facilities. The entity has determined that, beginning in the coming year, a significant number of its storage tanks and a significant amount of its other equipment will need to be removed, replaced, or modified to satisfy regulations that go into effect in varying stages over the next seven years. In addition, the entity has a present obligation to decontaminate the soil in the near term at its largest facility. ##### [410-30-55-9](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-9) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:4f26b220b43d0f6248664839eee1c2f1355cde73f50ff70475fa25f1b3df702b Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The entity hired a consultant to evaluate the technological, regulatory, and legal factors involved. Based on the consultant's findings, the entity estimated that total environmental expenditures over the next 7 years related to the tanks and equipment will aggregate approximately $5 million. Of this amount, approximately $4.75 million represents capital expenditures, which are expected to be recoverable through operations. The existing tanks have a net book value of $500,000, and the equipment has a net book value of $475,000. The cost of soil decontamination is estimated to be at least $1 million, which is material to the entity's operations, and may be as high as $3 million. Exposure to legal liability to third parties is considered remote. ##### [410-30-55-10](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-10) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:5ace42384dbccdbd47a76a846c49d822790669b18772773e5c1107754fdc0385 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

The potentially responsible party group has preliminarily agreed to an allocation that sets Entity A's share of the cost of remediating XYZ site at 6 percent.\] Entity A has accrued its best estimate of its obligation with respect to the site at December 31, 199X, \[which is $10 million and which is included in long-term liabilities and is expected to be disbursed over the next 10 years. If certain of the potentially responsible parties are ultimately not able to fund their allocated shares or the Environmental Protection Agency insists on a more expensive remediation approach,\] Entity A could incur additional obligations of up to $7 million. It is reasonably possible that Entity A's recorded estimate of its obligation may change in the near term. - With respect to the environmental obligation discussed above, the site was acquired in 1982, and, in connection with that acquisition, the former owner partially indemnified Entity A for environmental impacts occurring before the acquisition. \[Based on existing documentation indicating the years in which the business shipped wastes to XYZ and the terms of the indemnification in the acquisition agreement,\] Entity A \[believes it is probable that it will recover from the prior owners 50 percent of its allocated remediation costs for XYZ and, accordingly,\] has recorded a receivable of $5 million at December 31, 199X. ##### [410-30-55-17](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-17) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:5858210fc8a03c6c7532e22eb14741404bd70eb1bdb23dee8d2cca461eaf0266 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

Refine soil on dump property "1. The life of a garbage dump is not extended by refining its soil. Further, the condition of the soil after refining will not be improved over its condition when the garbage dump was constructed or acquired. Removal of the toxic waste restores the soil to its original uncontaminated condition." "2. Removal of toxic waste from the soil addresses an existing environmental concern. It also prevents that waste from leaching in the future. However, removing the waste does not mitigate or prevent future operations from creating future toxic waste. The risk will continue regardless of how much of the existing soil is refined." Conclusion: Soil refinement costs should be charged to expense unless the garbage dump is currently held for sale and the costs were incurred to prepare the garbage dump for sale. B. Install liner "1. The liner does not extend the useful life or improve the efficiency or capacity of the garbage dump. However, the liner has improved the garbage dump's safety compared to when the dump was constructed or acquired." "2. The liner addresses an existing and potential future problem. In this example, the garbage dump contains toxic waste from past operations and will likely generate toxic waste during future operations. The liner partly addresses the existing environmental problem by preventing future leaching of existing toxic waste into the soil.

Also referred to as a section 106 order.") to the potentially responsible party with the deepest pockets—XYZ—to undertake the remedial investigation-feasibility study. ##### [410-30-55-33](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-33) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:b2236694759a85e5adafae224944db0bd2e226eda4d99ceab5a1cc9a483ded60 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Because triple damages are authorized under section 106 of the Comprehensive Environmental Response, Compensation, and Liability Act, XYZ agreed to conduct the remedial investigation-feasibility study specified in the order and demanded that other identified potentially responsible parties participate in the effort. XYZ initially estimated the cost that would be incurred to perform the remedial investigation-feasibility study to be between $1 million and $2 million. Based on the limited information that was available about the site, information that XYZ had about its contribution to the site, and the number and financial condition of other potentially responsible parties, XYZ initially estimated that its ultimate share of this cost would prove to be in the range of 20 percent to 50 percent. XYZ also estimated that it would incur legal costs related to the remediation effort of $200,000 to $2 million in addition to any legal costs that might be incurred by any potentially responsible party group that might be formed. No amounts within any of these ranges were considered to be better estimates than any other amounts within any of these ranges. Because of a lack of information about the type and extent of the remediation effort that could be required, no range of cost of the overall remediation effort could be developed at this time. ##### [410-30-55-34](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-34) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:1915dc2a1cad20f4fc97ce0842f96375e6c629a5edd24fface8f2c8eb9513bf2 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Under threat of a contribution lawsuit by XYZ, a potentially responsible party group was formed late in 1988. The potentially responsible party group had the following three objectives: 1. a To implement the requirements of the unilateral administrative order in the most cost-effective and scientifically valid way 2. b To raise money and allocate costs among the potentially responsible parties willing to perform the work based on the types and relative quantities of wastes shipped to the site or another agreed-upon formula 3. c To recover costs from nonparticipating potentially responsible parties, if possible. ##### [410-30-55-35](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-35) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:18d5921923b9871dd79b3cacc3935d24d98c77536db7cee2a0e19ed4c2eba6d0 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Because of the lack of a good data base of factual information upon which to make sound allocation decisions agreeable to all, outside arbitration was used in 1989 to allocate fair share costs among participating potentially responsible parties. The arbitrator preliminarily apportioned 65 percent of the costs for the site to the four participating potentially responsible parties, as follows. - ![ ](https://asc.understandingaccounting.org/asc-img/GUID-906E4D43-3AD4-4BE7-A9B8-713A224D9A14-low.gif) XYZ 20% Potentially responsible party No. 2 20 Potentially responsible party No. 3 15 Potentially responsible party No. 4 10 65% Orphan share 25 Recalcitrant share 10 100% ##### [410-30-55-36](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-36) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:64a8c2a97a9329a86f1fda0c1e3d00c76f8705555222657081240659b98811cb Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

XYZ gained some understanding of the other participating potentially responsible parties' financial condition and believed each of them was able and likely to pay its full share of the costs of the remedial investigation-feasibility study.

Based on the amount already spent on legal costs and the results of potentially responsible party organization efforts, XYZ determined that $350,000 was the best estimate of its separate legal costs.

The remedial investigation-feasibility study was substantially completed in 1991. No changes were made to the potentially responsible parties allocation percentages as a result of the remedial investigation-feasibility study completion. The potentially responsible party group's initial estimate of the cost of implementing the remedy expected to be required by the Environmental Protection Agency was $25 million to $30 million. No amount within this range was considered to be a better estimate than any other amount within the range. This estimate included estimates of the cost of all elements of the remediation effort, including common legal, engineering, construction, monitoring, operation and maintenance costs (including postremediation monitoring for a period of 30 years), and so forth. ##### [410-30-55-40](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-40) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:a0544a4b5f794a357910bc5f332ee978fc856d3997f30a4c0375235972d06014 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. XYZ believed that potentially responsible party No. 2 and potentially responsible party No. 4 could and would pay their full shares of the cost of the remediation effort. Potentially responsible party No. 3, however, indicated that, because of its deteriorating financial position, it would likely be unable to pay more than two-thirds of its 15 percent share and none of its allocated amount attributed to the orphan and recalcitrant shares, or 10 percent of those costs.

Three years after site studies began, the Environmental Protection Agency and its outside contractors evaluated the reports submitted under the terms of the unilateral administrative order. A record of decision was issued by the Environmental Protection Agency on September 30, 1992, in which remedial actions based on the remedial investigation-feasibility study were selected and cost estimates were presented. The potentially responsible parties were requested to voluntarily implement the record of decision and again sign up to the terms demanded by the government. No preenforcement federal court review is permitted, even if the remedy specified in the record of decision is scientifically flawed, unattainable by available, proven technology, non-cost-effective, or open-ended. The potentially responsible parties had the following choices: perform the remedy specified in the record of decision voluntarily, or refuse to do work, in which case the Environmental Protection Agency would either issue another unilateral administrative order or perform the work using its contractor procurement systems and sue the potentially responsible parties for cost recovery. The potentially responsible parties agreed to perform the remedy specified in the record of decision and entered into a consent judgment. ##### [410-30-55-42](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-42) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:08d845e53b904fd5a4be206ba489374c9bebe2d5254d44ab44f25f8dd01dd581 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Note that the law requires the Environmental Protection Agency to review the record of decision and remedy within five years of its implementation by the potentially responsible parties. If the objectives of the record of decision have not been attained, the Environmental Protection Agency may make additional demands on the potentially responsible parties. If one or more potentially responsible parties believe they have paid a disproportionate share of the costs, they may track down other potentially responsible parties and sue them in a contribution action. Although requests for reimbursement from Superfund can also be made for allocations attributed to unidentified or unknown parties (the orphan share) under certain conditions, this is not usually allowed by terms and conditions of consent order settlements withthe Environmental Protection Agency. ##### [410-30-55-43](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-43) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:704ae782ac2dfd896fd6b26639e40bffede0b1443907afee0ca0cc2d414591a6 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Subtopic 450-20 requires accrual of a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Receipt in 1986 of an information request did not establish that a liability was probable because, notwithstanding the Environmental Protection Agency's interest in XYZ's connection, if any, to the site, it had not been established that XYZ was in fact associated with the site. As noted in paragraph [410-30-25-4](https://asc.understandingaccounting.org/asc/410/30/#410-30-25-4), however, receipt of notification that an entity may be a potentially responsible party compels the entity to action. ##### [410-30-55-44](https://asc.understandingaccounting.org/asc/410/30/#410-30-55-44) Pending content: no Source downloaded (UTC): 2026-09-10T00:21:44.319Z to 2026-09-10T00:21:44.319Z Record version: sha256:e149fdd1f990628df2579b40a9b6c6fd2ad6e5c81872c7c867ba32b9ad38e71e Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. When XYZ determined late in 1986 that it had, in fact, contributed hazardous substances to the site, the liability became probable. The criteria for recognition had not yet been met, however, because XYZ did not have sufficient information to reasonably estimate a minimum amount in the range of its liability that would be material to its financial statements.
