EPA's Brownfields Program is designed to empower 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. A brownfield is a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. EPA's Brownfields Program provides financial and technical assistance for brownfields revitalization, including grants for environmental assessment, cleanup, and job training. As requested by the FACA Negotiated Rulemaking Committee for All Appropriate Inquiry, the following analysis was done comparing the Brownfield Laws ten all appropriate inquiry criteria to alternative environmental assessment approaches, including commercial (ASTM), Federal (Brownfields Assessment Guidelines), and states. In addition, other provisions of these approaches that do not apply to any of the laws criterion but may be of interest are included. State laws and guidance documents for the following states were used to conduct this research and, where necessary, state officials were contacted to verify or gather information: 1. Florida; 2. Illinois; 3. Massachusetts; 4. Michigan; 5. New ersey; and 6. Pennsylvania.
