1. Screening Potential Sites: Electronic Decision Tree tool 1 Purpose: To screen sites for suitability for a solar PV or wind energy project.

2. Key Stakeholders State & Local Governments and Non-Profit Organizations To screen and prioritize existing sites in communities for their suitability for a renewable energy installation Renewable Energy Developers To introduce considerations unique to redevelopment of potentially contaminated sites and provide a common framework for interactions with state and local governments during project development phase Clean-up Project Managers To aid clean-up PMs to screen potentially contaminated sites for RE development potential Stakeholders & Targeted Sites Brownfields, Superfund sites, mines, or sites permitted to manage hazardous waste Landfills Targeted Sites: Potentially Contaminated or Underutilized Sites Underutilized rooftops and parking lotsAbandoned parcels

3. Decision Tree Summary -Explores solar (ground mount and/or rooftop) or wind (ground mount) -Can be used for small to large sites to assess potential for distributed, large-scale or utility-scale systems -Walks users through a series of Yes / No / Skip Questions -Supplements questions with additional information, tips and links to relevant resources -Generates reports of the screening results and user comments that can be printed or imported into other documents -Summary Site Screening Report -Data Entry Report -Site Comparison Report
