Demonstrations of Method Applicability under a Triad Approach for

Protection Agency's (EPA) Brownfields Initiative and other revitalization efforts have grown into major national programs that have changed the way contaminated property is perceived, addressed, and managed in the United States. In addition, there has been a shift within EPA and other environmental organizations in the way hazardous waste sites are cleaned up. Increasingly, project managers, regulators, technology providers, and other stakeholders are recognizing the value of implementing a more dynamic and flexible approach to site cleanup that focuses on real-time decision-making in the field to reduce costs, improve decision certainty, and expedite site closeout. The approach, known as Triad, uses (1) systematic project planning, (2) dynamic work strategies, and (3) real-time measurement technologies designed to increase confidence in the project (Figure 1). Figure 1. The Triad Approach Triad's best management and technical practices have been successfully implemented in a variety of regulatory frameworks, including Brownfields, Superfund, the Resource Conservation and Recovery Act (RCRA), management of underground storage tanks (UST), and voluntary cleanup programs. As a result, the EPA Brownfields and Land Revitalization Technology Support Center (BTSC) is preparing a series of technical bulletins to provide additional information on implementing specific aspects of the Triad approach. These bulletins are intended for technical project managers and team members. Non-technical managers or stakeholders may also present these bulletins to consultants and service providers to ensure Triad best management and technical practices are implemented appropriately at their sites. These bulletins provide sufficient information for less technical project managers and team members to request that critical Triad project elements be included in scope of work and planning documents. Demonstrations of Method Applicability (DMA) are a key component of using real-time measurement technologies and are presented in this bulletin through: 1. Answers to frequently asked questions on key aspects of DMAs 2. Examples of DMAs performed at hazardous waste sites: 3. Sources of additional information for communities and project teams that desire to implement DMAs and the Triad approach. EPA established the BTSC (see www.brownfieldstsc.org) to ensure that brownfields and other land revitalization decision-makers are aware of the full range of technologies and technical support services available for site assessments and cleanups and to help them make informed decisions about their sites. The center can help federal, state, local, and tribal officials evaluate strategies to streamline the site assessment and cleanup process at specific sites; identify, review, and communicate information about complex technology options; evaluate …
