What is the Environmentally Responsible Redevelopment & Reuse (ER3) Initiative?

The Environmentally Responsible Redevelopment and Reuse Initiative (often referred to as "ER3") encourages the cleanup and redevelopment and reuse of idle and abandoned sites in a manner that maximizes protection of public health and the environment.

EPA’s Environmentally Responsible Redevelopment and Reuse (ER3) initiative fosters sustainability and encourages sustainable reuse by:

  • Incorporating greener practices into the cleanup process at contaminated sites
  • Providing enforcement and other Agency-wide incentives to developers of contaminated sites
  • Leading and facilitating dialogue on sustainability principles and benefits among all stakeholders in the cleanup and reuse of contaminated sites
  • Assisting parties with identifying and incorporating sustainable development concepts into their projects

Sustainable development is not a new concept; organizations both within the EPA and outside the Agency specifically dedicated to promoting environmentally sensitive development have been part of the environmental effort for several years. 

EPA’s cleanup enforcement program implements the sustainability principles of ER3 by mainstreaming them into cleanup programs and by facilitating individual agreements and projects.  By providing incentives, assistance, and education to developers and others, EPA helps ensure that redevelopment of contaminated sites does not contribute to environmental problems in the future.
