Cape Fear Manufacturing Facility
Surface Disposal of Class B Residuals (Dedicated)
Brunswick County
Dear Division of Water Resources:
The following information is being submitted electronically:
1. Compliance and Monitoring Form (GW-59) for the 6 wells associated with the Sludge
Disposal Unit.
2. Laboratory analysis for these same wells.
3. Compliance Report Form GW-59A
4. Summary of the Groundwater Monitoring Results
As shown in the summary, some of the results in the monitoring wells are above the permit
limits. However, these results remain consistent with previous results and most results show
decreases in concentration. The regional office has received this data.
No additional actions are planned at this time.
If additional information is needed, please feel free to contact either myself on 910-371-5232 or
Larry Young on 910-264-2564.
Sincerely yours,
