Welcome to the BTSC

A brownfields site is defined as "real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant."

Decision-makers involved with preparing brownfields sites for productive reuse often require technical and legal assistance to fully understand the complexities of investigating and cleaning up contaminated sites.

The Brownfields and Land Revitalization Technology Support Center (BTSC, formerly the Brownfields Technology Support Center) is a cooperative effort to provide technical support to federal, state, local, and tribal officials for questions related to the use of innovative technologies and strategies for site assessment and cleanup.

EPA created the BTSC in 1998 to help decision-makers:

  • Evaluate strategies to streamline the site investigation and cleanup process
  • Identify and review information about complex technology options
  • Evaluate contractor capabilities and recommendations
  • Explain complex technologies to communities


EPA Office of Land and Emergency Management
The Office of Land and Emergency Management (OLEM) provides policy, guidance and direction for the Agency's emergency response and waste programs. At OLEM, we:

  1. Develop guidelines for the land disposal of hazardous waste and underground storage tanks;
  2. Provide technical assistance to all levels of government to establish safe waste management practices;
  3. Support state and local governments in redeveloping and reusing potentially contaminated sites through the Brownfields program;
  4. Respond to abandoned and active hazardous waste sites, as well as accidental chemical releases through the Superfund program; and
  5. Encourage innovative technologies to address contaminated soil and groundwater.

EPA Office of Brownfields and Land Revitalization (OBLR)
EPA's Office of Brownfields and Land Revitalization (OBLR) empowers states, communities, and other stakeholders in economic redevelopment to work together in a timely manner to prevent, assess, safely clean up, and sustainably reuse brownfields. EPA is funding assessment demonstration pilot programs to assess brownfields sites and to test cleanup and redevelopment models; job training pilot programs to provide training for residents of communities affected by brownfields to facilitate cleanup of brownfields sites and prepare trainees for future employment in the environmental field; and cleanup revolving loan fund programs to capitalize loan funds for the environmental cleanup of brownfields. These pilot programs are intended to provide EPA, states, tribes, municipalities, and communities with useful information and strategies as they continue to seek new methods to promote a unified approach to site assessment, environmental cleanup, and redevelopment.

While the BTSC focuses on providing technical assistance to do site assessment and remediation at the project level, OBLR focuses on other aspects. Brownfields Stakeholders involved in the selection and use of technologies for environmental cleanup can visit OBLR's website to learn more about the brownfields grant programs that are available. Through collaboration with OBLR, BTSC provides support to the Brownfields program. The BTSC works closely with OBLR and can provide direct technical assistance to communities that participate in OBLR's initiatives and grant programs.

EPA Office of Research and Development
EPA’s Office of Research and Development (ORD) is the principal scientific research arm of EPA. ORD is organized into three national laboratories and two national centers, and conducts research and fosters the use of science and technology in fulfilling EPA's mission. Technology Support Center services include site-specific assistance in the areas of Superfund, RCRA, and Brownfields; technology transfer activities; technical assistance; development and testing of management techniques; and the development of training courses.
