Significance and Use4.1 UseThe standard is intended for use on a voluntary basis by an estimator of costs and liabilities for environmental matters.The user may elect to apply this standard for any or all uses outlined
40、 in the Purpose. Application of this standard for one use doesnot compel application of the standard for all or any other use.4.2 PrinciplesThe following principles are an integral part of this standard and should be used to resolve ambiguity or disputeregarding the interpretation of estimated costs
41、 and liabilities for environmental matters.4.2.1 Caution When Repurposing EstimatesThe estimator should exercise care when repurposing an estimate generated forone objective and audience. For example, an estimator may use the expected value approach on a given cost and liability, and findthat the “f
42、inancial assurance estimate” uses unique financial assumptions (inflation, discount rate, time horizon) specified by a stateregulator, while a “project controls” or “reserve” forecast for the very same cost and liability - will use differing financial factors.4.2.2 Uncertainty Not EliminatedEven tho
43、ugh an estimate of costs and liabilities for environmental matters is prepared inaccordance with this standard, uncertainty remains with regard to, among other things, the resolution of contractual, technological,regulatory, legislative, and judicial issues, which could affect the costs and liabilit
44、ies. However, inherent uncertainty in estimatesshould not prevent an estimate from being made.4.2.3 Periodic Review of Assumptions and EstimatesAssumptions underlying these estimates should be reviewed periodicallyreviewed, documented and periodically analyzed for the purpose of incorporating additi
45、onal information that may becomeavailable. new information. There is a preference for current information over historical assumptions if the current information iscomprehensive and comparable. Subsequent improvements in estimates should be made as more information becomes available,or as recognition
46、 benchmarks or obligating eventsFor example, changes in occur. For example, for remediation of an individualsite, such assumptions include changes to the conceptual site model; contaminant concentration data found in soil, groundwater,air and sediments; the selection of different remedial technologi
47、es; the indication of a preferred alternative by the governingagency; the weighting of alternatives; the probability of failure of a remedial technology to achieve the desired outcome in the timeanticipated; the probability of accelerated or delayed enforcement; the probability of a compressed remed
48、ial construction timetable;the explicit or implied value of impacted drinking water, wetlands, and other natural resources; changes to the default values ofE2137 173fines and penalties and their associated tax consequences; and the ability to pay of PRPsregulatory requirements, technology, orother c
49、ounterparties. Changes in available information such as contaminant data, market prices, regulatory requirements,precedential court findings, technology, counterparty ability to pay, dutyholder ability to pay, property use, inflation, inflation anddiscount rates, or other issues may affect the basis for the estimates, therefore necessitating revisions.
