Dear Mr. Thomas:
On behalf of the NC Division of Water Quality, we respectfully request that you consider the
following comments within your review of the 404 Individual Permit request for the above referenced
property:
1. The Division requires full plan sheets at a scale of no smaller than 1"=50' with topographic
contours shown and all jurisdictional features overlaid in order for our office to adequately
comment on the proposed avoidance and minimization for the project.
2. Although the Division cannot fully review the avoidance and minimization for this project as
noted above, we request that the applicant consider alternatives that completely avoid or reduce
impacts to Stream SC5 only.
3. The Division requests that the applicant provide detailed engineering drawings that include all fill
slopes, energy dissipaters, bank stabilization, etc. at all impact areas. The plans should include
cross section details for all impact areas, temporary impacts for construction/dewatering,
restoration of all temporary impacts, and a hydrological analysis indicating that streams below the
proposed impacts will continue to function/flow.
4. The Division requests that the applicant provide documentation of contingency plans in the event
of landfill liner failure and groundwater exposure.
