ASTM E2893-13e1

4.1.1 Minimize Total Energy Use and Maximize Use of Renewable Energy—Reducing total energy use while also identifying means to increase the use of renewable energies throughout the cleanup. Possible methods may include reducing energy use, use of energy efficient equipment, use of onsite renewable resources (for example, wind, solar), and purchase of commercial energy from renewable resources.

4.1.2 Minimize Air Pollutants and Greenhouse Gas Emissions—Reducing total air emissions, including emissions of air pollutants and greenhouse gases, throughout the cleanup. Possible methods may include minimizing the generation and transport of airborne contaminants and dust, efficient use of emitting equipment (for example, vehicles and heavy equipment), use of advanced emission controls, and use of cleaner fuels or hybrid technologies.

4.1.3 Minimize Water Use and Impacts to Water Resources—Minimizing the use of water and impacts to water resources throughout the cleanup. Possible methods may include conserving water use in cleanup processes, use of water efficient products, water capture and reclamation for reuse, water efficient revegetation, and employing traditional 4.1.4 Reduce, Reuse, and Recycle Materials and Waste—Minimizing the use of virgin materials and generation of waste throughout the cleanup as well as maximizing the use of recycled materials. Possible methods may include using recycled and locally generated materials, reusing waste materials (for example, concrete made with coal combustion products), diverting construction and demolition debris from disposal by recycling recovered resources, and using rapidly renewable materials or certified wood products.

4.1.5 Protect Land and Ecosystems—Reducing impacts to the land and ecosystem services throughout the cleanup. Possible methods may include minimizing the area requiring activity and use limitations by the removal or destruction of contaminants; identifying the presence of and limiting the disturbance of mature, non-invasive, native vegetation, surface hydrology, soils, and 4.2 Professional Experience—This guide requires the skills of a lead environmental professional and project team, as appropriate, to evaluate and apply greener cleanup practices, processes, and technologies to each cleanup phase while meeting regulatory program-specific requirements and ensuring protection of human health and the environment. This guide presumes the 4.3 Uncertainty in Greener Cleanups—Professional judgment, interpretation, and some uncertainty are inherent in the process even when decisions are based upon objective scientific principles and accepted industry practices. Although such uncertainties are inevitable, they typically will not detract from the ability of the user to achieve meaningful improvements in the site cleanup.

4.4 Regulatory Context—The 4.4.1 The user shall comply with health and safety requirements under the Occupational Safety and Health Act and parallel state statutes and regulations.

4.4.2 This guide may not be appropriate for certain cleanups, such as some emergency response actions, that do not allow sufficient time for its application.

4.4.3 Implementation of this 4.5 Process Implementation—This guide may be initiated at any time during any cleanup phase, including during: site assessment; 4.6 Process Overview—At initiation, the user should review Section 4.6.1 Section 5, Planning and Scoping, describes information the user should collect and consider to assist in making several site-specific, user-defined decisions for implementing the guide.

4.6.2 Section 6, BMP Process, describes steps for identifying, prioritizing, selecting, and implementing BMPs.

4.6.3 Section 7, Quantitative Evaluation, describes a process for implementing a 4.6.4 Section 8 describes recommended documentation and reporting on the implementation of the guide.

4.6.5 Section 9 provides keywords for indexing and searching purposes.

4.6.6 This guide includes four appendices.
