|Significance and Use|
4.1.1 This practice is intended for use on a voluntary basis by parties who wish to evaluate known 4.1.2 This practice is intended to meet the business community's need for a written, practical reference describing a scientifically sound approach to investigating a 22.214.171.124 This practice does not address the evaluation of business environmental risks in light of data collected through the Phase II ESA process. Such evaluation is a function of site- and transaction-specific variables, and of the 126.96.36.199 Likewise, this practice does not define the threshold levels at which target analytes pose a concern of significance to the user. Users may apply this practice not only in light of applicable regulatory criteria and relevant liability principles, but also to meet self-defined objectives.
188.8.131.52 If a Phase II ESA conducted in accordance with this practice provides sufficient information from which the 4.1.3 Use Not Limited to CERCLA—This practice is designed to assist a 4.1.4 Site- and Transaction-Specific—The scope of a 4.1.5 Use by Other Parties—This practice does not define whether or to what extent any person other than the user may use or rely upon a Phase II ESA prepared for the 4.2 Principles—The following principles are an integral part of this practice and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the user or Phase II Assessor.
4.2.1 Elimination of Uncertainty—No 184.108.40.206 Failure to Detect—Even when 220.127.116.11 Limitations of Information—The effectiveness of a Phase II ESA may be compromised by limitations or defects in the information used to define the objectives and scope of the investigation, including inability to obtain information concerning historical site uses or prior site assessment activities despite the efforts of the user and Phase II Assessor to obtain such information in accordance with .
18.104.22.168 Chemical Analysis Error—4.2.2 Level of Assessment—Phase II ESAs do not generally require an exhaustive assessment of environmental conditions on a property. There is a point at which the cost of information obtained and the time required to obtain it outweigh the benefit of the information and, in the context of private transactions and contractual responsibilities, may become a material detriment to the orderly conduct of business. If the 4.2.3 Comparison With Subsequent Inquiry—The justification and adequacy of the findings of a 4.2.4 Data Usability—Investigation data generally only represent the site conditions at the time the data were generated and site conditions can be dynamic. Therefore, the usability of data collected as part of a Phase II ESA may have a finite lifetime depending on the application and use being made of the data. To the extent that investigation data would fall within the scope of data used in a 4.2.5 Phase II Assessor Does Not Provide Legal or Business Advice—The Phase II ESA is intended to develop and present sound, scientifically valid data concerning actual site conditions. It shall not be the role of the Phase II Assessor to provide legal or business advice.
1.1 This practice covers a process for conducting a Phase II environmental site assessment (1.1.1 A user's interest in the presence or likely presence of substances in environmental media at a property may arise in a wide variety of legal, regulatory, and commercial contexts, and may involve diverse objectives including those listed in . This practice contemplates that the user and the Phase II Assessor will consult to define the scope and objectives of investigation in light of relevant factors, including without limitation the substances released or possibly released at the 1.1.2 A Phase II ESA in accordance with this practice may be conducted after site assessment activities in accordance with Practice for Phase I Environmental Site Assessments: Phase I Environmental Site Assessment Process, Practice for Environmental Site Assessments: Phase I Environmental Site Assessment for Forestland or Rural Property, EPA’s All Appropriate Inquiries (AAI) Rule, 40 C.F.R. Part 312, or Practice for 1.2 Objectives—This practice is intended for use where a user desires to obtain sound, scientifically valid data concerning actual property conditions, whether or not such data relate to property conditions previously identified as 1.2.1 Objective 1—Assess whether there has been a 1.2.2 Objective 2—Provide information relevant to identifying, defining or implementing landowner “1.2.3 Objective 3—Develop threshold knowledge of the presence of substances on properties within the scope of the 1.2.4 Objective 4—Provide information relevant to identifying, defining and evaluating property conditions associated with target analytes that may pose risk to human health or the environment, or risk of bodily injury to persons on the property and thereby give rise to potential liability in tort.
1.2.5 Objective 5—Provide information relevant to evaluating and allocating business environmental risk in transactional and contractual contexts, including transferring, financing and insuring properties, and due diligence relating thereto.
1.2.6 Objective 6—Provide information to support disclosure of liabilities and contingent liabilities in financial statements and securities reporting.
1.2.7 Additional information concerning these six objectives may be found in the Legal Appendix, .
1.3 Scope of Assessment in Relation to Objectives—The scope of a 1.3.1 In developing the scope of work and in evaluating data and information concerning the property, the 1.3.2 A single round of sampling and 1.3.3 This practice does not require full 1.4 Needs of the User—The user and Phase II Assessor must have a mutual understanding of the context in which the Phase II ESA is to be performed and the objectives to be met by the investigation, i.e. the specific questions to be answered or problems to be resolved by the 1.4.1 The degree of confidence desired by the 1.5 Limitations—This practice is not intended to supersede applicable requirements imposed by regulatory authorities. This practice does not attempt to define a legal standard of care either for the performance of professional services with respect to matters within its scope, or for the performance of any individual Phase II ESA.
