Subject: Request for Additional Information for Hampstead POD - Pender County - DWR #20230465
Ms. Hong,
Thank you for your response to the Division's previous Request for Additional Information received June 22, 2023. We
have reviewed the response and require additional information in order to complete our review of the application for
the above noted project. Please provide a response to these items by August 11, 2023. The Division will consider the
application on hold until a complete receipt is received.
1. Notes on the plan sheets for the culvert installation under the access road states "add culvert inlet and outlet
protection". The Division does not recommend inlet and outlet protection for wetland connectivity culverts as
they will increase the wetland impact, however if these protections are necessary for other regulatory programs,
please ensure that they are shown on the impact maps and impacts are accurately calculated to account for
these permanent impacts.
2. One culvert proposed along the access road (circled in red below) does not appear to be installed to provide
wetland connectivity. Please provide a culvert within the wetland for connectivity.
3. The Division recommends that another wetland connectivity culvert be considered at the location circled in
purple on the image below.
4. The Division is concerned with the proposed installation of a concrete washout pit within a wetland. NPDES
regulations recommend that these be located away from surface waters, and Sheet CG501 specifically states: "
Washout Pit may be located no closer than 50' to drains, inlets or surface waters". Wetlands are defined by
DWR regulations as surface waters. Please relocate the washout pit in accordance with these requirements.
5. It appears that the trapezoidal channel shown below in Blue has not been calculated as permanent wetland
impact.
6. The impact summary table you have provided does not match the impact sheets included with the plan set.
a. Impact areal, Wetland WA, is listed as permanent impact on the impact plan sheet but no acreage
amount is included in the impact table.
b. Impact area 3, Wetland WB, is listed as 0.426 acres on the summary table and 0.429 acres on the impact
sheet
c. Impact area 5, Wetland WB, is listed as 0.253 acres on the summary table and 0.254 acres on the impact
sheet
d. Impact area 6, Wetland WB, is listed as dewatering on the impact plan sheet, and land clearing on the
impact summary table. The cover letter indicates this area is to be mechanically cleared. Please clarify
exactly what activities will be occurring within these areas. It is unclear that regular equipment access
to the stockpile area, the sediment basin, and equipment movement throughout the site during
construction would be able to avoid these areas. Areas that will be accessed by construction equipment
are likely to be compacted and permanently impacted. If you propose these areas will not be
permanently impacted please provide clear details that show how the site will be constructed without
allowing equipment to access these areas.
e. Impact area 7, Wetland WC, is listed as 0.016 acres on the summary table and 0.027 acres on the impact
sheet
f. Impact area 8, Wetland WC, is listed as 0.027 acres on the summary table and 0.064 acres on the impact
sheet
g. Impact area 9, Wetland WD, is listed as 0.001 acres on the summary table and 0.013 acres on the impact
sheet
h. Impact area 10, Wetland WD, is listed as 0.013 acres on the summary table and 0.044 acres on the
impact sheet
i. The impact summary table indicates areas 11, 12 and 13 but these are not shown on the impact sheet
7. Once these individual impact discrepancies are resolved, please ensure total impact amounts are updated and
that the mitigation amount is satisfactory and/or submit a new mitigation statement of availability if necessary.
