1、Designation: E1903 11Standard Practice forEnvironmental Site Assessments: Phase II EnvironmentalSite Assessment Process1This standard is issued under the fixed designation E1903; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

2、year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice2covers a process for conducting a Phase IIenvironmental site assessment (ESA) of a parcel of pro

3、pertywith respect to the presence or the likely presence of sub-stances including but not limited to those within the scope ofthe Comprehensive Environmental Response, Compensationand Liability Act (CERCLA) (e.g., hazardous substances),pollutants, contaminants, petroleum and petroleum products,and c

4、ontrolled substances and constituents thereof. It specifiesprocedures based on the scientific method to characterizeproperty conditions in an objective, representative, reproduc-ible, and defensible manner. To promote clarity in definingPhase II ESA objectives and transparency in communicatingand in

5、terpreting Phase II ESA results, this practice specifiesadherence to requirements for documenting the scope ofassessment and constraints on the conduct of the assessmentprocess.1.1.1 A users interest in the presence or likely presence ofsubstances in environmental media at a property may arise ina w

6、ide variety of legal, regulatory, and commercial contexts,and may involve diverse objectives including those listed in1.2. This practice contemplates that the user and the Phase IIAssessor will consult to define the scope and objectives ofinvestigation in light of relevant factors, including without

7、limitation the substances released or possibly released at theproperty, the nature of the concerns presented by their presenceor likely presence, the portion of the property to be investi-gated, the information already available, the degree of confi-dence needed or desired in the results, the degree

8、 of investi-gatory sampling and chemical testing needed to achieve suchconfidence, and any applicable time and resource constraints.This practice requires that Phase II activities be conducted sothat the resulting scope of work is performed, and the statedobjectives are achieved, in a scientifically

9、 sound manner.1.1.2 A Phase II ESA in accordance with this practice mayfollow site assessment activities in accordance with PracticeE1527 for Phase I Environmental Site Assessments: Phase IEnvironmental Site Assessment Process, Practice E2247 forEnvironmental Site Assessments: Phase I Environmental

10、SiteAssessment for Forestland or Rural Property, EPAs AllAppropriate Inquiries (AAI) Rule, 40 C.F.R. Part 312, orPractice E1528 for Limited Environmental Due Diligence:Transaction Screen Process. Users of this practice should haveknowledge and understanding of Practice E1527 and the AAIRule because

11、a Phase II ESA may address a likely presence ofhazardous substances or petroleum products identified inprevious assessment reports as a recognized environmentalcondition (REC). In defining the scope and purposes of a PhaseII ESA, however, previous decisions to classify propertyconditions or areas as

12、 RECs, or to refrain from doing so, are notdeterminative as to whether investigation of the same condi-tions or areas is appropriate to meet the objectives of the PhaseII ESA.1.2 ObjectivesThis practice is intended for use in anysituation in which a user desires to obtain sound, scientificallyvalid

13、data concerning actual property conditions, whether ornot such data relate to property conditions previously identifiedas RECs or data gaps in Phase I ESAs. Without attempting todefine all such situations, this practice contemplates that usersmay seek such data to inform their evaluations, conclusio

14、ns,and choices of action in connection with objectives that mayinclude, without limitation, one or more of the following:1.2.1 Objective 1Assess whether there has been a releaseof hazardous substances within the meaning of CERCLA, forpurposes including landowner liability protections (i.e., inno-cen

15、t landowner, bona fide prospective purchaser, and contigu-ous property owner).1.2.2 Objective 2Provide information relevant to identi-fying, defining and implementing landowner “continuing ob-ligations,” or the criteria established under CERCLA (e.g.,1This practice is under the jurisdiction of ASTM

A “practice” is adefinitive set of instruction

A “guide,” in contrast, is a compendium of information ora series of options that does not recommend a specific course of action. A guideincreases the awareness of information and approaches in a given subject area.

21、.2.4 Objective 4Provide information relevant to identi-fying, defining and evaluating property conditions associatedwith target analytes that may pose risk to human health or theenvironment, or risk of bodily injury to persons on the propertyand thereby give rise to potential liability in tort.1.2.5

22、 Objective 5Provide information relevant to evaluat-ing and allocating business environmental risk in transactionaland contractual contexts, including transferring, financing andinsuring properties, and due diligence relating thereto.1.2.6 Objective 6Provide information to support disclo-sure of lia

23、bilities and contingent liabilities in financial state-ments and securities reporting.1.2.7 Additional information concerning these six objec-tives may be found in the Legal Appendix, Appendix X1.1.3 Scope of Assessment in Relation to ObjectivesThescope of a Phase II ESA is related to the objectives

24、 of theinvestigation. Both scope and objectives may require ongoingevaluation and refinement as the assessment progresses.1.3.1 In developing the scope of work and in evaluating dataand information concerning the property, the Phase II Assessormust determine whether the available information is suff

25、icientto meet the objectives of the investigation. Even after conduct-ing Phase II activities to generate additional data, the Phase IIAssessor must independently evaluate the sufficiency of thedata in relation to the objectives. As the investigation pro-gresses, the objectives may be refined or red

26、efined in consul-tation between the user and the Phase II Assessor.1.3.2 A single round of sampling and chemical testing maynot always provide data sufficient to meet the chosen objec-tives. If not, this practice contemplates additional sampling inan iterative sequence that concludes when the availa

27、ble dataare sufficient. This practice also acknowledges, however, thatthe user may instead elect either to redefine the objectives sothat they can be met with the data available, or to terminate theinvestigative process without meeting the stated objectives.The Phase II Assessment report must disclo

28、se any respect inwhich available data are insufficient to meet objectives.1.3.3 This practice does not require full site characteriza-tion in every instance, but may be used to carry out aninvestigation sufficient for that purpose if desired to meet theusers objectives.1.4 Needs of the UserThe user

29、and Phase II Assessormust have a mutual understanding of the context in which thePhase II ESA is to be performed and the objectives to be metby the investigation, i.e. the specific questions to be answeredor problems to be resolved by the Phase II ESA. The scope ofPhase II activities must be defined

30、 in relation to those objec-tives.1.4.1 The degree of confidence desired by the user influ-ences the scope of the investigation and the evaluation of data.More extensive testing and more iterations of sampling andanalysis may be needed if the objectives require detailedconclusions with high confiden

31、ce. Less testing and feweriterations of sampling and analysis may be needed if theobjectives of the assessment include only general conclusions.1.5 LimitationsThis practice is not intended to supersedeapplicable requirements imposed by regulatory authorities.This practice does not attempt to define

32、a legal standard of careeither for the performance of professional services with respectto matters within its scope, or for the performance of anyindividual Phase II Environmental Site Assessment.1.6 Organization of This PracticeThis practice has ninesections and four appendices.
