1.1 This guide provides a site risk management screening framework for the human use of: (1)inactive solid waste disposal sites, unregulated solid waste disposal sites, and sites impacted by chemical releases that are not currently within an environmental regulatory agency cleanup program; (2) sites with anthropogenic background concentrations of chemicals of concern; and (3) sites that have chemical contaminants. These sites may be underutilized or routinely used, for example, pedestrian, recreational, repetitive entertainment, or single event sites.

1.2 This guide provides instruction on evaluating and judging the acceptability of beneficial uses (active and passive recreation) for an inactive or unregulated solid waste disposal site or chemically impacted site.

1.3 This guide may be implemented in conjunction with ASTM's Standard Guide for Stakeholder Engagement on Environmental Risk Management and Climate (E3356) with respect to community engagement activities; see Section 6 of Guide E3356 for more information.

1.4 This guide should not be used as a justification to avoid, minimize, or delay implementation of specific cleanup activities as required by law or regulation.

1.5 This guide may not be used to characterize (that is, environmentally assess) a site for the purpose of ownership transfer.

1.6 Users of this guide make professional judgments that only apply to a particular site, at a particular date and time, and do not warrant safe conditions otherwise. It is possible that a significant environmental exposure condition exists at a site but was missed by the user of this guide or the Environmental Professional who led the risk screening evaluation, or that the condition was introduced subsequent to the evaluation. The risk screening evaluation of a site by an Environmental Professional is not intended to be exhaustive; there may be significant unknown conditions that may not be apparent through reasonable site characterization efforts. Those who use the final reports generated through the use of this guide are cautioned to understand the limits described in the Project Technical Summary and Risk Assessment Screening form in Appendix X1.

1.7 Users of this guide should comply with all applicable federal, Tribal, state, and local statutes and regulations requiring and/or relating to protection of human health. This includes, and is not limited to, laws and regulations relating to health and safety of the people using an inactive or unregulated solid waste disposal site or a chemically impacted site, the surrounding community, and/or public sector and private sector personnel who are involved in the management or oversight of inactive or unregulated solid waste disposal site or chemically impacted sites.

1.8 This guide is composed of the following sections: Referenced Documents; Terminology; Significance and Use; Planning and Scoping; Background Research and Interviews; Site Visit; Records Analysis; Conceptual Site Model; Risk Assessment Screening; and Appendix X1, Example Project Technical Summary and Risk Assessment Screening Form.

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.

1.10 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.
