4.1 Flexibility Users may desire to incorporate sustainable aspects within the scalable framework throughout any or all phases of the cleanup, or any size of site.

4.2 Considerations The information provided in this guide provides a framework to evaluate sustainable aspects in the context of site cleanup. The guide helps users identify factors and activities they may want to consider in cleanup projects, while protecting human health and the environment.

4.3 Sustainable Performance Criterion Based on the sustainable objectives identified for the site, users should implement one or more best management practices that substantially benefit each of the sustainable aspects (environmental, social and economic), see Section 6 for details. The user should demonstrate these benefits through publicly available documentation. Substantial benefits must be over and above those achieved by existing regulatory requirements, unless a regulatory agency adopts this guide for cleanup sites. In that case the regulatory agency will determine what constitutes substantial benefits under its own regulations.

4.4 Transparency Goal The user should document the activities and evaluations performed while using this guide. The documentation is needed to demonstrate the sustainable benefits through public disclosure and transparency. See Section 8 for more information.

4.5 Stakeholder Involvement The user should engage stakeholders as early as possible in the cleanup process. The planning and scoping phase of the project should identify the perspectives and values of the stakeholders and use that information to inform decision-making (see Guide E2348 ). Users should consider the input of different stakeholders, including the community, and implement BMPs favored by community members wherever possible. Consideration may include review of and integration into the communitys approved Master Plan.

4.6 Elimination of Uncertainty Professional judgment, interpretation, and some uncertainty are inherent in the process, even when exercised in accordance with objective scientific principles. In addition, new concepts and methods for integrating sustainable objectives into cleanup results will develop in the future.

4.7 Not every property will warrant the same level of evaluation of alternatives or approaches for integrating sustainable objectives in cleanup. The appropriate level of assessment and evaluation should be guided by the complexity of the cleanup project, the extent of impacts, the relative costs and benefits of various cleanup options and sustainable improvements, the potential limitation of resources for the cleanup, the future use of the site, other considerations associated with the site and affected community, and the regulatory requirements.

4.8 Worker health and safety issues are one of many considerations in the site cleanup decision-making process. If two approaches are equally protective of human health and the environment and fully meet regulatory requirements, then the one that is expected to provide greater worker safety should generally be preferred. Worker health and safety should not be used as a rationale for avoiding cleanup at sites.

4.9 The guide is divided into various sections for ease of use. See Fig. 1 .

4.10 The spirit and intent of the guide promotes improvements in cleanup through integration of sustainable objectives.

4.11 The user should consider the over-all affect of site cleanup in a holistic manner, including the adverse impacts of the cleanup and the consequences for the community. In order to accomplish this, during cleanup planning, the user should consider the sustainable core elements to provide direction and help define actions.

4.12 Cost Considerations As with all projects, costs are an important factor. It is the prerogative of the user to determine how to evaluate and accommodate the financial implications of using the guide (see Guide E2137 ). The economic well-being of persons neighboring a cleanup and others within the community should be considered in the evaluation. The user should document the cost considerations. See Section 8 for information about documentation.

4.13 Regulatory Context Regulatory contexts where this guide is applicable include voluntary cleanups, brownfields cleanups performed in compliance with state voluntary cleanup programs, or brownfield initiatives, state-led enforcement cleanups, for example, most underground storage tank corrective actions by states paid through the American Recovery and Reinvestment Act of 2009, CERCLA removal and remedial actions, and other corrective actions required under RCRA. Users should, however, determine the regulatory context for each site and comply with all applicable laws, regulations and guidance (for example, environmental laws under CERCLA, RCRA, TSCA), including health and safety requirements under the OSHA and parallel state statutes and regulations.

4.14 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This guide presents a framework that allows and encourages the user to address sustainable aspects (environmental, economic and social) within cleanup projects. The user may implement this guide to integrate sustainable objectives into cleanup while working within applicable regulatory criteria.

1.2 The guide provides an overarching, consistent, transparent and scalable framework that helps the user identify and incorporate sustainable best management practices (BMPs) into site cleanup (which includes assessment and remediation), and enables the user to perform measurement of BMPs during the cleanup process. See Appendix X1 for example BMPs.

1.3 The guide is intended to encourage incremental steps to incorporate sustainable elements into cleanup projects. The user chooses whether to pursue BMP implementation alone (Section 6 ) or to also measure the benefits of the implemented BMPs (Sections 6 and 7 ). The user also chooses the phases of the cleanup to which they apply the guide.

1.4 The guide should be implemented within the existing site assessment and remediation process. The approach described in this guide should be used with other existing technical tools and policy to encourage the consideration of a more holistic approach with a broader range of cleanup options and activities than traditionally employed (NICOLE 2012 ( 1 ) ) ² .

1.5 BMPs implemented under this guide should address all three aspects of sustainability: environmental, economic and social, while assuring that human health and safety as well as ecological risks are addressed. The goal of implementing BMPs is to take actions to address the sustainable objectives identified for the site.

1.6 3.1.17 defines sustainable objectives; 3.1.15.1 defines sustainable aspects; 5.3 provides detail about core elements; and Section 6 describes a process to identify, evaluate, select, and implement BMPs.

1.7 While the guide specifically applies to the cleanup phases of a project (which includes assessment and remediation phases), decisions made in the cleanup may influence reuse activities. The anticipated reuse of the site may influence cleanup activities.

1.8 This guide may not be used as a justification for elimination or reduction of cleanup actions that are required to protect human health and the environment.

1.9 The guide is composed of the following sections: Section 2 Referenced Documents, Section 3 Terminology, Section 4 Significance and Use, Section 5 Planning and Scoping; Section 6 Selection and Implementation of best management practices (BMPs); Section 7 Quantifying Site-Specific results from BMPs; and Section 8 Documentation. Fig. 1 Using the guide is provided to assist the user in navigating the guide.

1.10 The guide is intended to provide an overarching framework for integrating sustainable objectives in cleanup projects. The user may choose to consider the ASTM Work Item WK 35161 for greener cleanups along with this guide to more fully address the environmental elements of a project.

1.11 When implementing this guide, the user must comply with all applicable federal, state, and local statutes and regulations requiring or relating to protection of human health and the environment. This includes, but is not limited to, laws and regulations relating to health and safety, of the surrounding community, or on-site workers. No action taken in connection with implementing this guide should generate unacceptable human health or ecological risks.
