Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process

Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process

SIGNIFICANCE AND USE
4.1 Uses—This practice is intended for use on a voluntary basis by parties who wish to assess the environmental condition of commercial real estate taking into account commonly known and reasonably ascertainable information. While use of this practice is intended to constitute all appropriate inquiries for purposes of the LLPs, it is not intended that its use be limited to that purpose. This practice is intended primarily as an approach to conducting an inquiry designed to identify recognized environmental conditions in connection with a subject property. No implication is intended that a person shall use this practice in order to be deemed to have conducted inquiry in a commercially prudent or reasonable manner in any particular transaction. Nevertheless, this practice is intended to reflect good commercial and customary practice (see 1.6).  
4.2 Clarifications on Use:  
4.2.1 Use Not Limited to CERCLA—This practice is designed to assist the user in developing information about the environmental condition of a subject property  and as such has utility for a wide range of persons, including those who may have no actual or potential CERCLA liability and/or may not be seeking the LLPs.  
4.2.2 Residential Tenants/Purchasers and Others—No implication is intended that it is currently customary practice for residential tenants of multifamily residential buildings, tenants of single-family homes or other residential real estate, or purchasers of dwellings for one’s own residential use, to conduct an environmental site assessment in connection with these transactions. Thus, these transactions are not included in the term commercial real estate transactions, and it is not intended to imply that such persons are obligated to conduct an environmental site assessment in connection with these transactions for purposes of all appropriate inquiries or for any other purpose. In addition, no implication is intended that it is currently customary practice for environmental site ...
SCOPE
1.1 Purpose—The purpose of this practice is to define good commercial and customary practice in the United States of America for conducting an environmental site assessment2 of a parcel of commercial real estate with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) (42 U.S.C. § 9601) and petroleum products. As such, this practice is intended to permit a user to satisfy one of the requirements to qualify for the innocent landowner,  contiguous property owner, or bona fide prospective purchaser limitations on CERCLA liability (hereinafter, the “landowner liability protections,” or “LLPs”): that is, the practice that constitutes all appropriate inquiries into the previous ownership and uses of the property consistent with good commercial and customary standards and practices as defined at 42 U.S.C. § 9601(35)(B). (See Appendix X1 for an outline of CERCLA’s liability and defense provisions.) Controlled substances are not included within the scope of this practice. Persons conducting an environmental site assessment as part of an EPA Brownfields Assessment and Characterization Grant awarded under CERCLA 42 U.S.C. § 9604(k)(2)(B) must include controlled substances as defined in the Controlled Substances Act (21 U.S.C. § 802) within the scope of the assessment investigations to the extent directed in the terms and conditions of the specific grant or cooperative agreement. Additionally, an evaluation of business environmental risk  (BER) associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this practice (see 1.4 and Section 13).  
1.1.1 Recognized Environmental Conditions—The goal of the processes established by this practice is to identify recognized environmental conditions. The term recognized environmental condition means (1) the presence of hazardous substances or petroleum produc...

Standard Guide for Developing Representative Background Concentrations at Sediment Sites — Framework Overview, Including Conceptual Site Model Considerations

SIGNIFICANCE AND USE
4.1 Intended Use:  
4.1.1 This guide may be used by various parties involved in sediment corrective action programs, including regulatory agencies, project sponsors, environmental consultants, toxicologists, risk assessors, site remediation professionals, environmental contractors, and other stakeholders.  
4.2 Updates to CSM:  
4.2.1 The CSM should be updated as needed and refined to describe the physical properties, chemical composition and occurrence, biological features, and environmental conditions of the sediment corrective action project (Guide E1689).  
4.3 Reference Material:  
4.3.1 This guide should be used in conjunction with other ASTM guides listed in 2.1 (especially Guides E3163, E3164, E3240, E3242, and E3344), as well as the material in the References section (including (1)).  
4.4 Flexible Site-Specific Implementation:  
4.4.1 This guide provides a systematic but flexible framework to accommodate variations in approaches by regulatory agencies and by the user based on project objectives, site complexity, unique site features, regulatory requirements, newly developed guidance, newly published scientific research, changes in regulatory criteria, advances in scientific knowledge and technical capability, and unforeseen circumstances.  
4.5 Regulatory Frameworks:  
4.5.1 This guide is intended to be applicable to a broad range of local, state, tribal, federal, or international jurisdictions, each with its own unique regulatory framework. As such, this guide does not provide a detailed discussion of the requirements or guidance associated with any of these regulatory frameworks, nor is it intended to supplant applicable regulations and guidance. The user of this guide will need to be aware of the regulatory requirements and guidance in the jurisdiction where the work is being performed.  
4.6 Systematic Project Planning and Scoping Process:  
4.6.1 When applying this guide, the user should undertake a systematic project planning and sco...
SCOPE
1.1 This guide provides an overarching framework for the development of representative sediment background concentrations at contaminated sediment sites. It is intended to inform, complement, and support but not supersede the guidelines established by local, state, tribal, federal, or international agencies.  
1.2 Technically defensible representative sediment background concentrations are critical for several purposes (Guide E3242) (1)2. These include sediment site delineation, establishing remedial goals, remedy selection, assessment of risks posed by representative background concentrations, and establishing appropriate post-remedial monitoring plans.  
1.3 As part of the overall framework presented in this guide, Guide E3240 provides a general discussion of how Conceptual Site Model (CSM) development fits into the risk-based corrective action framework for contaminated sediment sites. However, not all elements of a sediment CSM need to be considered when developing representative sediment background concentrations; those that do are discussed in detail in Section 7 of this guide.  
1.3.1 As additional data are collected and analyzed, the CSM should be updated as needed.  
1.3.2 This guide is related to several other guides. Guide E3344 describes how to select an appropriate background reference area(s). Guide E3164 covers the sampling methodologies used in the field to obtain sediment samples (whether from the sediment site or background reference area[s]), and Guide E3163 discusses appropriate laboratory methodologies to use for the chemical analysis of potential contaminants of concern (PCOCs) in sediment samples. Guide E3242 describes how to evaluate candidate background data to obtain representative background data sets (including statistical, geochemical, and forensic considerations) and then how to use them to calculate representative sediment background concentrations.

Standard Practice for Limited Environmental Due Diligence: Transaction Screen Process

SIGNIFICANCE AND USE
4.1 Uses—This practice sets forth a procedure for conducting limited environmental due diligence. This practice is intended for use on a voluntary basis by parties who wish to assess the environmental condition of a subject property where a Phase I Environmental Site Assessment is, initially, deemed to be unnecessary by the user and the parties do not seek CERCLA LLPs. This practice is intended primarily as a commercially prudent or reasonable approach to conducting an inquiry designed to identify potential environmental concerns in connection with a subject property.  
4.2 Clarifications on Use:  
4.2.1 Use Not Intended for CERCLA Liability Protection—This document is not intended to permit a user to satisfy CERCLA LLPs, that is, the practices that constitute all appropriate inquiries into the previous ownership and uses of the subject property consistent with “generally accepted good commercial and customary standards and practices” as defined in 42 U.S.C. §9601(35)(B).  
4.2.2 Transaction Screen Does Not Identify Recognized Environmental Conditions—This practice does not define a scope of assessment sufficient to identify recognized environmental conditions as defined in Practice E1527 and Practice E2247.  
4.2.3 Residential Tenants/Purchasers and Others—Although this practice is not intended for residential purposes, it may be used at the user’s discretion for residential tenants of multifamily residential buildings, tenants of single-family homes or other residential real estate, or purchasers of dwellings for residential use to conduct a transaction screen in connection with these transactions.  
4.2.4 Site-Specific—This practice is site-specific in that it relates to assessment of environmental conditions at a subject property. Consequently, this practice does not address many additional issues raised in transactions such as purchases of business entities, or interests therein, or of their assets, that may well involve environmental liabilities pertaini...
SCOPE
1.1 Purpose—The purpose of this practice is to define a good practice in the United States of America for conducting a transaction screen2 for a subject property where the user wishes to conduct limited environmental due diligence (that is, less than a  Phase I Environmental Site Assessment). If the driving force behind the environmental due diligence is a desire to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs), this practice should not be applied. Instead, the ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property may be used.  
1.1.1 This practice will not satisfy the requirement to conduct all appropriate inquiries into the previous ownership and uses of the subject property consistent with “generally accepted good commercial and customary standards and practices” as defined in 42 U.S.C. §9601(35)(B) to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs). Users who desire to conduct environmental due diligence to qualify for one of the CERCLA  LLPs should conduct assessment activities in conformity with “Standards and Practices for All Appropriate Inquiries,” 40 C.F.R. Part 312; ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property.  
1.2 An evaluation of business environmental risk associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this practice. See Sections 1.4 and 9.

Standard Guide for Conducting Daphnia magna Life-Cycle Toxicity Tests

SIGNIFICANCE AND USE
5.1 Protection of an aquatic species requires prevention of unacceptable effects on populations in natural habitats. Toxicity tests are conducted to provide data that may be used to predict what changes in numbers and weights of individuals might result from similar exposure to the test material in the natural aquatic environment. Information might also be obtained on the effects of the material on the health of the species.  
5.2 Results of life-cycle tests with D. magna are used to predict chronic effects likely to occur on daphnids in field situations as a result of exposure under comparable conditions.  
5.2.1 Life-cycle tests with D. magna are used to compare the chronic sensitivities of different species, the chronic toxicities of different materials, and study the effects of various environmental factors on the results of such tests.  
5.2.2 Life-cycle tests with D. magna are used to assess the risk of materials to aquatic organisms (see Guide E1023) or derive water quality criteria for aquatic organisms (1).3  
5.2.3 Life-cycle tests with D. magna are used to extrapolate the results of chronic toxicity tests on the same test material with the same species in another water or with another species in the same or a different water. Most such predictions take into account the results of acute toxicity tests, and so the usefulness of the results of a life-cycle test with D. magna may be increased by reporting the results of an acute toxicity test (see Guide E729) conducted under the same conditions. In addition to conducting an acute toxicity test with unfed D. magna, it may be relevant to conduct an acute test in which the daphnids are fed the same as in the life-cycle test to see if the presence of that concentration of that food affects the results of the acute test and the acute-chronic ratio (ACR) (see 10.3.1).  
5.2.4 Life-cycle tests are used to evaluate the biological availability of, and structure-activity relationships between, test materials and t...
SCOPE
1.1 This guide covers procedures for obtaining laboratory data concerning the adverse effects of a test material (added to dilution water, but not to food) on Daphnia magna Straus, 1820, during continuous exposure throughout a life-cycle using the renewal or flow-through techniques. These procedures also should be useful for conducting life-cycle toxicity tests with other invertebrate species and cladocerans from the same genus (for example, Daphnia pulex), although modifications might be necessary.  
1.2 These procedures are applicable to most chemicals, either individually or in formulations, commercial products, or known mixtures. With appropriate modifications, these procedures can be used to conduct tests on temperature, dissolved oxygen, pH, and on such materials as aqueous effluents (also see Guide E1192), leachates, oils, particulate matter, sediments, and surface waters. The technique, (renewal or flow-through), will be selected based on the chemical characteristics of the test material such as high oxygen demand, volatility, susceptibility to transformation (biologically or chemically), or sorption to glass.  
1.3 Modification of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of standard test procedures. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information on new concepts and procedures for conducting life-cycle toxicity tests with D. magna. Appendix X3 provides modifications for conducting the chronic toxicity test method with D. pulex Leydig, 1860.

Standard Guide for Remedy Selection Integrating Risk-Based Corrective Action and Non-Risk Considerations

SIGNIFICANCE AND USE
4.1 This guide is intended for use within a RBCA process or other risk-based framework for protection of human health and the environment that is based on an evaluation of sources, exposure pathways, and receptors.  
4.2 This guide is intended to identify the factors that should be considered in the selection and implementation of an appropriate remedial action to address COCs present in environmental media at the site at concentrations above the remedial action levels. The specific process used to select the remedial action will vary widely from site to site. However, in all cases, the selected remedial action should be both a protective remedial action (that is, achieves the risk-based remedial action objectives) and an acceptable remedial action (that is, satisfies the non-risk remedial action objectives).
SCOPE
1.1 This guide covers the selection of appropriate remedial actions at sites where a release of chemicals (for example, vapor-phase, dissolved-phase, or non-aqueous phase liquids (NAPL)) into the environment has occurred. This overall remedy selection process is illustrated in Fig. 1. The guide is intended to be applied within a risk-based corrective action (RBCA) framework.
FIG. 1 Remedy Selection Process  
1.2 The purpose of this guide is to facilitate the selection of acceptable remedial actions and to minimize bad decisions leading to the selection of remedial actions that do not satisfy both the risk-based remedial action objectives and the non-risk remedial action objectives.  
1.3 This guide is intended to be applied at sites that require a remedial action to address unacceptable human heath or ecological risks, other regulatory requirements, and/or other unacceptable site conditions. Prior to use of this guide, a site assessment should be completed resulting in: (1) the establishment of remedial action objectives, (2) a determination that a remedial action is required to achieve the remedial action objectives, (3) an identification of site areas requiring a remedial action, and (4) a conceptual site model that reflects the results of the site assessment. The risk-based remedial action objectives are assumed to have been established using RBCA or another risk-based assessment method that results in the identification of appropriate remedial action objectives based on an evaluation of sources, exposure pathways, and potential receptors. Remedial action objectives may be established using Guide E1739, Guide E2081, and/or Guide E2205. In addition, applicable federal, state, and local regulations, statutes, and policies should be followed and should form the basis for determining risk-based and non-risk remedial action objectives. The remedial action objectives may include resource protection standards and the prevention of aesthetic or nuisance impacts in addition to protection of human health and the environment.  
1.4 Each risk-based remedial action objective for an exposure pathway will typically include numeric remedial action levels for each chemical of concern (COC). Remedial action levels may also be developed for non-risk remedial action objectives such as resource protection standards. The non-risk remedial action levels may include thickness or mobility criteria for NAPL. The selected remedy must be effective and timely for each remedial action objective based on the consideration of the associated exposure pathway or resource protection standard.  
1.5 To facilitate the selection of acceptable remedial actions, this guide establishes a process for remedy selection (Fig. 2) that involves:

Standard Guide for Ecological Considerations for the Use of Chemical Dispersants in Oil Spill Response: Tropical Environments

SIGNIFICANCE AND USE
3.1 This guide is meant to aid local and regional spill response teams who may apply it during response planning and spill events.  
3.2 This guide presents data on the effects of surface oil, dissolved oil and dispersed oil on components of tropical environments. These data can aid in decision-making related to the use of dispersants to minimize environmental damage from oil spills.
SCOPE
1.1 This guide covers recommendations for use of chemical dispersants to assist in the control of oil spills and is written with the goal of minimizing the environmental impacts of oil spills. Aesthetic and socioeconomic factors are not considered; although, these and other factors are often important in spill response.  
1.2 Each on-scene commander has available several means of control or cleanup of spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This guide presents general guidelines only. The dispersibility of the oil with the chosen dispersant should be evaluated in compliance with relevant government regulations. Oil, as used in this guide, includes crude oils and fuel oils. Differences between individual dispersants and to a certain degree, differences between different oils are not considered.  
1.4 This guide is one of several related to dispersant considerations in different environments. The other standards are listed in Section 2.  
1.5 This guide applies to marine and estuarine environments but not to freshwater environments.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 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.  
1.8 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 Limited Environmental Due Diligence: Transaction Screen Process

SIGNIFICANCE AND USE
4.1 Uses—This practice sets forth a procedure for conducting limited environmental due diligence. This practice is intended for use on a voluntary basis by parties who wish to assess the environmental condition of a subject property where a Phase I Environmental Site Assessment is, initially, deemed to be unnecessary by the user and the parties do not seek CERCLA LLPs. This practice is intended primarily as a commercially prudent or reasonable approach to conducting an inquiry designed to identify potential environmental concerns in connection with a subject property.  
4.2 Clarifications on Use:  
4.2.1 Use Not Intended for CERCLA Liability Protection—This document is not intended to permit a user to satisfy CERCLA LLPs, that is, the practices that constitute all appropriate inquiries into the previous ownership and uses of the subject property consistent with “generally accepted good commercial and customary standards and practices” as defined in 42 U.S.C. §9601(35)(B).  
4.2.2 Transaction Screen Does Not Identify Recognized Environmental Conditions—This practice does not define a scope of assessment sufficient to identify recognized environmental conditions as defined in Practice E1527 and Practice E2247.  
4.2.3 Residential Tenants/Purchasers and Others—Although this practice is not intended for residential purposes, it may be used at the user’s discretion for residential tenants of multifamily residential buildings, tenants of single-family homes or other residential real estate, or purchasers of dwellings for residential use to conduct a transaction screen in connection with these transactions.  
4.2.4 Site-Specific—This practice is site-specific in that it relates to assessment of environmental conditions at a subject property. Consequently, this practice does not address many additional issues raised in transactions such as purchases of business entities, or interests therein, or of their assets, that may well involve environmental liabilities pertaini...
SCOPE
1.1 Purpose—The purpose of this practice is to define a good practice in the United States of America for conducting a transaction screen2 for a subject property where the user wishes to conduct limited environmental due diligence (that is, less than a  Phase I Environmental Site Assessment). If the driving force behind the environmental due diligence is a desire to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs), this practice should not be applied. Instead, the ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property may be used.  
1.1.1 This practice will not satisfy the requirement to conduct all appropriate inquiries into the previous ownership and uses of the subject property consistent with “generally accepted good commercial and customary standards and practices” as defined in 42 U.S.C. §9601(35)(B) to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs). Users who desire to conduct environmental due diligence to qualify for one of the CERCLA  LLPs should conduct assessment activities in conformity with “Standards and Practices for All Appropriate Inquiries,” 40 C.F.R. Part 312; ASTM E1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process or ASTM E2247: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process for Forestland or Rural Property.  
1.2 An evaluation of business environmental risk associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this practice. See Sections 1.4 and 9.

Standard Guide for Conducting Daphnia magna Life-Cycle Toxicity Tests

SIGNIFICANCE AND USE
5.1 Protection of an aquatic species requires prevention of unacceptable effects on populations in natural habitats. Toxicity tests are conducted to provide data that may be used to predict what changes in numbers and weights of individuals might result from similar exposure to the test material in the natural aquatic environment. Information might also be obtained on the effects of the material on the health of the species.  
5.2 Results of life-cycle tests with D. magna are used to predict chronic effects likely to occur on daphnids in field situations as a result of exposure under comparable conditions.  
5.2.1 Life-cycle tests with D. magna are used to compare the chronic sensitivities of different species, the chronic toxicities of different materials, and study the effects of various environmental factors on the results of such tests.  
5.2.2 Life-cycle tests with D. magna are used to assess the risk of materials to aquatic organisms (see Guide E1023) or derive water quality criteria for aquatic organisms (1).3  
5.2.3 Life-cycle tests with D. magna are used to extrapolate the results of chronic toxicity tests on the same test material with the same species in another water or with another species in the same or a different water. Most such predictions take into account the results of acute toxicity tests, and so the usefulness of the results of a life-cycle test with D. magna may be increased by reporting the results of an acute toxicity test (see Guide E729) conducted under the same conditions. In addition to conducting an acute toxicity test with unfed D. magna, it may be relevant to conduct an acute test in which the daphnids are fed the same as in the life-cycle test to see if the presence of that concentration of that food affects the results of the acute test and the acute-chronic ratio (ACR) (see 10.3.1).  
5.2.4 Life-cycle tests are used to evaluate the biological availability of, and structure-activity relationships between, test materials and t...
SCOPE
1.1 This guide covers procedures for obtaining laboratory data concerning the adverse effects of a test material (added to dilution water, but not to food) on Daphnia magna Straus, 1820, during continuous exposure throughout a life-cycle using the renewal or flow-through techniques. These procedures also should be useful for conducting life-cycle toxicity tests with other invertebrate species and cladocerans from the same genus (for example, Daphnia pulex), although modifications might be necessary.  
1.2 These procedures are applicable to most chemicals, either individually or in formulations, commercial products, or known mixtures. With appropriate modifications, these procedures can be used to conduct tests on temperature, dissolved oxygen, pH, and on such materials as aqueous effluents (also see Guide E1192), leachates, oils, particulate matter, sediments, and surface waters. The technique, (renewal or flow-through), will be selected based on the chemical characteristics of the test material such as high oxygen demand, volatility, susceptibility to transformation (biologically or chemically), or sorption to glass.  
1.3 Modification of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of standard test procedures. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information on new concepts and procedures for conducting life-cycle toxicity tests with D. magna. Appendix X3 provides modifications for conducting the chronic toxicity test method with D. pulex Leydig, 1860.

Standard Guide for Remedy Selection Integrating Risk-Based Corrective Action and Non-Risk Considerations

SIGNIFICANCE AND USE
4.1 This guide is intended for use within a RBCA process or other risk-based framework for protection of human health and the environment that is based on an evaluation of sources, exposure pathways, and receptors.  
4.2 This guide is intended to identify the factors that should be considered in the selection and implementation of an appropriate remedial action to address COCs present in environmental media at the site at concentrations above the remedial action levels. The specific process used to select the remedial action will vary widely from site to site. However, in all cases, the selected remedial action should be both a protective remedial action (that is, achieves the risk-based remedial action objectives) and an acceptable remedial action (that is, satisfies the non-risk remedial action objectives).
SCOPE
1.1 This guide covers the selection of appropriate remedial actions at sites where a release of chemicals (for example, vapor-phase, dissolved-phase, or non-aqueous phase liquids (NAPL)) into the environment has occurred. This overall remedy selection process is illustrated in Fig. 1. The guide is intended to be applied within a risk-based corrective action (RBCA) framework.
FIG. 1 Remedy Selection Process  
1.2 The purpose of this guide is to facilitate the selection of acceptable remedial actions and to minimize bad decisions leading to the selection of remedial actions that do not satisfy both the risk-based remedial action objectives and the non-risk remedial action objectives.  
1.3 This guide is intended to be applied at sites that require a remedial action to address unacceptable human heath or ecological risks, other regulatory requirements, and/or other unacceptable site conditions. Prior to use of this guide, a site assessment should be completed resulting in: (1) the establishment of remedial action objectives, (2) a determination that a remedial action is required to achieve the remedial action objectives, (3) an identification of site areas requiring a remedial action, and (4) a conceptual site model that reflects the results of the site assessment. The risk-based remedial action objectives are assumed to have been established using RBCA or another risk-based assessment method that results in the identification of appropriate remedial action objectives based on an evaluation of sources, exposure pathways, and potential receptors. Remedial action objectives may be established using Guide E1739, Guide E2081, and/or Guide E2205. In addition, applicable federal, state, and local regulations, statutes, and policies should be followed and should form the basis for determining risk-based and non-risk remedial action objectives. The remedial action objectives may include resource protection standards and the prevention of aesthetic or nuisance impacts in addition to protection of human health and the environment.  
1.4 Each risk-based remedial action objective for an exposure pathway will typically include numeric remedial action levels for each chemical of concern (COC). Remedial action levels may also be developed for non-risk remedial action objectives such as resource protection standards. The non-risk remedial action levels may include thickness or mobility criteria for NAPL. The selected remedy must be effective and timely for each remedial action objective based on the consideration of the associated exposure pathway or resource protection standard.  
1.5 To facilitate the selection of acceptable remedial actions, this guide establishes a process for remedy selection (Fig. 2) that involves:

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. In those cases in which the testing requirements for certain products are unique or at variance with these general procedures, the product specification testing requirements shall control.
