The 2000 RCRA National Conference was conducted August 15‐17, 2000, in Washington, D.C., to allow state and federal authorities to review regulatory issues associated with the Resource Conservation and Recovery Act (RCRA) program. One of the RCRA reform issues discussed at the conference included the Government Performance and Results Act (GPRA) Environmental Indicators (EI). EIs have been designed to provide clarity in cleanup objectives and spur progress towards meeting the U.S. Environmental Protection Agency's (USEPA's) national RCRA cleanup goals. This article focuses on the human exposure indicator and, more specifically, on indoor air exposures and how to assess whether such exposure is actually occurring. While indoor air exposure can be a critical component of the human exposure scenarios, realistic predictions of the exposures are difficult to produce. This article provides an overview of the regulatory issues related to the indoor air exposure pathway. It also discusses the use of modeling in criteria development and risk evaluation and presents a case study of how the USEPA wants the modeling to occur, and an opinion of where this RCRA reform issue is heading and how to evaluate indoor air exposures.
