I want to mention briefly the question about site drainage that has been asked many times about the project. We have asked Earth Tech to make a technical review of the site drainage around the facility based on the layout of our plant . And the analysis identified the current drainage flow of the site area and the predicted changes to the flow as a result of construction of the Elk Run Energy Station. And the design goal of the study was to show a net positive result to the drainage systems of the area. There is a concern that there could be additional b/c of our facility or we could backup and restrict natural drainage b/c of our facility.

The results of the study showed improvements to the drainage flows, and less potential for flooding in the area as a result of construction with certain mitigation measures, such as the 2 detention basins which are included on our site, and the 100-year peak discharge flow would be reduced by approximately 70% or more. So there’s a signficiant potential to actually improve the drainage system in the area rather than degrade it.
