Item 1. The CSA was specifically designed to assess the coal ash management
areas of the facility. Sufficient information is available to prepare the
groundwater corrective action plan for the ash management area of the
facility. Data limitations are discussed in Section 14 of the CSA report.
Continued groundwater monitoring at the site will refine the understanding of
potential impacts to groundwater and soil.

Item 2. No imminent hazards to human health and the environment requiring
immediate action were identified by the CSA.

Item 5. The groundwater assessment plan for the CSA as approved by NCDENR
was specifically developed to assess the coal ash management areas of the
facility for the purposes of developing a corrective action plan for
groundwater. Other areas of possible contamination on the property were not
evaluated.
