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
