Standard Guide for Estimating Monetary Costs and Liabilities for Environmental Matters

SIGNIFICANCE AND USE
4.1 Use—The 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 in the Purpose. Application of this standard for one use does not compel application of the standard for all or any other use.  
4.2 Principles—The following principles are an integral part of this standard and should be used to resolve ambiguity or dispute regarding the interpretation of estimated costs and liabilities for environmental matters.  
4.2.1 Framing the Estimate—It is important to understand and document/disclose the framework in which the estimate is being made, including identification of the requestor, estimator and relevant qualifications, purpose of the estimate, audience/user of the estimate, limitations, assumptions, and a description of what constitutes a reliable estimate.  
4.2.2 Caution When Repurposing Estimates—The estimator should exercise care when repurposing an estimate generated for one objective and audience. For example, an estimator may use the expected value approach on a given cost and liability, and find that the “financial assurance estimate” uses unique financial assumptions (inflation, discount rate, time horizon) specified by a state regulator, while a “project controls” or “reserve” forecast – for the very same cost and liability -- will use differing financial factors.  
4.2.3 Uncertainty Not Eliminated—Even though an estimate of costs and liabilities for environmental matters is prepared in accordance 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 liabilities. However, inherent uncertainty in estimates should not prevent an estimate from being made.  
4.2.4 Periodic Review of Assumptions and Estimates—Assumptions underlying estimates should be reviewed, documented and p...
SCOPE
1.1 Purpose—The purpose of this document is to provide a standard guide for good commercial and customary practice in estimating costs and liabilities for environmental matters.2 Many possible uses for estimates of costs and liabilities for environmental matters exist, including but not limited to business decision making and portfolio optimization, due diligence and communications involving acquisitions and divestitures, regulatory requirements, third-party lawsuits, insurance premium calculation and claim settlement, change of property use, revitalization, compliance planning, construction and project control, analysis of remedial alternatives, budgeting, strategic planning, audit defense, financing, and investment analysis by shareholders. The use of estimated costs and liabilities developed in accordance with this standard may be subject to other standards applicable to the matter involved. For example, it is not intended to supersede accounting and actuarial standards. This standard does not address the establishment of reserves or disclosure requirements.  
1.2 Objectives—The objective of this standard is to provide guidance on approaches for estimating costs and liabilities for environmental matters.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Detecting Hot Spots Using Point-Net (Grid) Search Patterns

SIGNIFICANCE AND USE
4.1 Search sampling strategies have found wide utility in geologic exploration where drilling is required to detect subsurface mineral deposits, such as when drilling for oil and gas. Using such strategies to search for buried wastes and subsurface contaminants, including volatile organic compounds, is a logical extension of these strategies.  
4.2 Systematic sampling strategies are often the most cost-effective method for searching for hot spots.  
4.3 This practice may be used to determine the risk of missing a hot spot of specified size and shape given a specified sampling pattern and sampling density.  
4.4 This practice may be used to determine the smallest hot spot that can be detected with a specified probability and given sampling density.  
4.5 This practice may be used to select the optimum grid sampling strategy (that is, sampling pattern and density) for a specified risk of not detecting a hot spot.  
4.6 By using the algorithms given in this practice, one can balance the cost of sampling versus the risk of missing a hot spot.  
4.7 Search sampling patterns may also be used to optimize the locations of additional groundwater monitoring wells or vadose zone monitoring devices.
SCOPE
1.1 This practice provides equations and nomographs, and a reference to a computer program, for calculating probabilities of detecting hot spots (that is, localized areas of soil or groundwater contamination) using point-net (that is, grid) search patterns. Hot spots, more generally referred to as targets, are presumed to be invisible on the ground surface. Hot spots may include former surface impoundments and waste disposal pits, as well as contaminant plumes in groundwater or the vadose zone.  
1.2 For purposes of calculating detection probabilities, hot spots or buried contaminants are presumed to be elliptically shaped when projected vertically to the ground surface, and search patterns are square, rectangular, or rhombic. Assumptions about the size and shape of suspected hot spots are the primary limitations of this practice, and must be judged by historical information. A further limitation is that hot spot boundaries are usually not clear and distinct.  
1.3 In general, this practice should not be used in lieu of surface geophysical methods for detecting buried objects, including underground utilities, where such buried objects can be detected by these methods (see Guide D6429).  
1.4 Search sampling would normally be conducted during preliminary investigations of hazardous waste sites or hazardous waste management facilities (see Guide D5730). Sampling may be conducted by drilling or by direct-push methods. In contrast, guidance on sampling for the purpose of making statistical inferences about population characteristics (for example, contaminant concentrations) can be found in Guide D6311.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Remedial Action Resiliency to Climate Impacts

SIGNIFICANCE AND USE
4.1 This guide outlines various techniques for evaluating and mitigating the impacts of climate change and weather extremes on remediation systems, activity and use limitations, stewardship and remediation activities.  
4.2 Users include: local, state, federal, tribal, and international agencies; the military; environmental consultants; developers; financial institutions; non-governmental organizations; environmental advocacy groups; commercial businesses, industries, and the interested public.  
4.3 A 2018 ITRC survey of 45 state environmental agencies found key Best Management Practices (BMPs) and adaptation strategies for resilient cleanup. These include remedy infrastructure and disaster planning for chemical releases as an important part of the state’s clean-up program. In some cases, such considerations are now required by state regulations and included in policy and guidance (ITRC, 2018 (3)).  
4.4 Adaptation is important because it is about considering and addressing the changing frequency and intensity of extreme events. Adaptation differs from resiliency by anticipating, planning and preparing for impacts under both current and future climate conditions.  
4.5 There are many models and different strategies on adapting to climate and weather extremes, including those in the European Union (European Union, 2013 (4), IPPC, 2001 (5)).  
4.6 The USGAO has reported benefits from evaluating climate risks for large projects. (USGAO, 2019 (6)) GAO found most Superfund sites have not factored the increasing frequency and severity of extreme weather events and climate impacts into the design of remedies. This has resulted in unplanned releases of chemicals into the environment at some sites.  
4.7 Companies and organizations operating in accordance with ISO 14001-2015 may find this guide useful for meeting the long-term compliance obligation requirements of Clause 5.2 (ISO 14001-2015)  
4.8 This guide should be integrated into the fundamentals of an organizati...
SCOPE
1.1 The potential for increasing climate and extreme weather impacts requires more attention be given to their effect on sites where chemicals have been released. All stages of remediation planning and implementation should consider and address potential climate and extreme weather impacts, such as flooding and wildfires, that may affect remedy sustainability, continued protection of human and ecological receptors, the surrounding community, and the environment. Both resiliency to current extreme weather impacts as well as adaptation to longer-term impacts due to the changing climate should be considered. Consideration of climate and extreme weather impacts during stabilization, remedial investigation, feasibility studies, remedial design, remedial action implementation, long-term operations and management, and site stewardship may lead to the use of innovative technologies and more robust remediation strategies.  
1.2 The conceptual site model is designed to inform all aspects of site decision making, inclusive of the investigation, feasibility study, design and implementation. It may be the most important mechanism to integrate consideration of climate impacts. The conceptual site model should be continuously developed and refined, while considering new knowledge about climate factors and potential impacts to the site.  
1.3 This ASTM resiliency guide identifies the best management practices for incorporating resiliency and vulnerability assessment into all stages of the site cleanup process. Historically, resiliency was primarily considered or contemplated in the final stages of the cleanup process, such as in the operation and maintenance stage, after a remedy was completely in place at a site. Gradually, resiliency has extended to earlier stages of the cleanup process. This may include initial vulnerability assessment for site stabilization and extending into the remedial investigation and feasibility stage. This ...

Standard Guide for Monitoring Sediment in Watersheds

SIGNIFICANCE AND USE
4.1 This guide is intended to be used in the planning stage or phase of developing a sediment monitoring program. This guide is an assembly of the components common to all aspects of watershed sediment monitoring and fulfills a need in the development of a common framework for a better coordinated and a more unified approach to sediment monitoring in watersheds.  
4.2 The user of this guide is not assumed to be a trained technical practitioner in the water quality, sedimentation, or hydrology fields. The intended users are managers and planners who need information to develop a water quality monitoring program or project with an emphasis in sediment and hydrology. Sediment specialists will also find information on procedures, equipment, methodology, and operations to conduct a monitoring program.  
4.3 This guide is used during the planning process of developing, designing, and re-evaluating a sediment monitoring program.
SCOPE
1.1 Purpose—This guide is intended to provide general guidance on a watershed monitoring program directed toward sediment. The guide offers a series of general steps without setting forth a specific course of action. It gives advice for establishing a monitoring program, not an implementation program.  
1.2 Sedimentation as referred to in this guide is the detachment, entrainment, transportation, and deposition of eroded soil and rock particles. Specific types or parameters of sediment may include: suspended sediment, bedload, bed material, turbidity, wash load, sediment concentration, total load, sediment deposits, particle size distribution, sediment volumes and particle chemistry. Monitoring may include not only sediments suspended in water but sediments deposited in fields, floodplains, and channel bottoms.  
1.3 This guide applies to surface waters as found in streams and rivers; lakes, ponds, reservoirs, estuaries, and wetlands.  
1.4 Limitations—This guide does not establish a standard procedure to follow in all situations and it does not cover the detail necessary to define all of the needs of a particular monitoring objective or project. Other standards and guides included in the reference and standard sections describe in detail the procedures, equipment, operations, and site selection for collecting, measuring, analyzing, and monitoring sediment and related constituants.  
1.5 Additional ASTM and U.S. Geological Survey standards applicable to sediment monitoring are listed in Appendix X1 and Appendix X2. Due to the large number of optional standards and procedures involved in sediment monitoring, most individual standards are not referenced in this document. Standards and procedures have been grouped in the appendices according to the type of analyses or sampling that would be required for a specific type of measurement or monitoring.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Ecological Considerations for the Use of Oil Spill Dispersants in Freshwater and Other Inland Environments, Lakes and Large Water Bodies

SIGNIFICANCE AND USE
3.1 This guide is meant to aid response teams who may use it during spill response planning and spill events.  
3.2 This guide should be adapted to site specific circumstance.
SCOPE
1.1 This guide covers the use of oil spill dispersants to assist in the control of oil spills. The guide is written with the goal of minimizing the environmental impacts of oil spills; this goal is the basis on which the recommendations are made. Aesthetic and socioeconomic factors are not considered, although these and other factors are often important in spill response.  
1.2 Spill responders have available several means to control or clean up spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This is a general guide only. Oil, as used in this guide, includes crude oils and refined petroleum products. Differences between individual dispersants or between different oil products are not considered. The dispersibility of the oil with the chosen dispersant should be evaluated.  
1.4 The guide is organized by habitat type, for example, small ponds and lakes, rivers and streams, and land. It considers the use of dispersants primarily to protect habitats from impact (or to minimize impacts).  
1.5 This guide applies only to freshwater and other inland environments. It does not consider the direct application of dispersants to subsurface waters.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 This guide does not address getting regulatory approval.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Drying Shrinkage of Mortar Containing Hydraulic Cement

SIGNIFICANCE AND USE
4.1 This test method establishes a selected set of conditions of temperature, relative humidity and rate of evaporation of the environment to which a mortar specimen of stated composition shall be subjected for a specified period of time during which its change in length is determined and designated “drying shrinkage.”  
4.2 The drying shrinkage of mortar as determined by this test method has a linear relation to the drying shrinkage of concrete made with the same cement and exposed to the same drying conditions.4 Hence this test method may be used when it is desired to develop data on the effect of a hydraulic cement on the drying shrinkage of concrete made with that cement.
SCOPE
1.1 This test method determines the change in length on drying of mortar bars containing hydraulic cement and graded standard sand.  
1.2 The values stated in SI units are to be regarded as standard. When combined standards are referenced, the selection of measurement system is at the user’s discretion subject to the requirements of the referenced standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure).2
