The EPA Region 6 Compliance Assurance and Enforcement Division requested Science Advisory Board (SAB) review of the Region’s Geographic Information System Screening Tool (GISST) (DRAFT)

**** This is from the DRAFT. The final can be found here: sab-06-011 ********************


The whole report is about 40 pages. This is from the introductory letter.

• The current version of the GISST provides only a single vulnerability or impact score that can mask important differences in individual data layers used for an assessment. Such differences must be considered when evaluating the potential environmental impacts of project alternatives as part of an overall strategy to achieve assessment objectives.
• The current version of the GISST does not adequately utilize modern statistical science in its development of numerical scoring. These issues must be considered when combining and evaluating data layers in the GISST.
