REQUEST FOR MORE INFORMATION
Dear Mr. Wren:
On November 16, 2010,the Express Review Program of the Division of Water Quality(DWQ)received
your application dated November 15,2010 to fill or otherwise impact 0.40 acres of wetland for the
purpose of constructing the proposed Mountaire facility expansion and rail realignment project. On
November 22, 2010 we received partial information from our original request for information;however,
none of the requested stormwater management plan information was received. The DWQ has determined
that your application will require additional information. Please provide the following information so
that we may continue to review your project and prevent denial of your application as required by 15A
NCAC 2H .0506:
Additional Information Requested
1. Stormwater Management Plan:
a. From the soil report dated October 14, 2010,the seasonal high water table(SHWT)elevation
is within 24 inches from the existing grade at the two boring locations. Our discussion with a
professional from ECS Carolinas,LLP who conducted the subsurface investigation indicates
that at the time of the test,the existing ground surface had not been disturbed, cut or
excavated. Unless you have sufficient evidence to support the elevation of SHWT as
reported in your submittal,the infiltration basin will not be an appropriate stormwater BMP
for this location.You may consider a closed-bottom sand filter,a constructed wetland or
another device if the elevation of the SHWT remains an issue.
b. If the SHWT elevation is determined such that the infiltration basin can be appropriately
used:
i. Please add a note in the construction/installation notes to ensure that the basin will be
installed only when all upstream areas draining to the BMP have been stabilized.
Grass must be established in areas specified as grass.

ii. Please revise the cover letter to indicate that the basin has been sized for the 2-inch
storm and not the 1-inch storm.
iii. Revise the design calculations and the hydrograph report to ensure that the entire
runoff from the 2-inch storm is diverted to the infiltration basin.
iv. There is a standard manhole detail on plan sheet SP-5,but it would be helpful to
provide details for MH2O and MH24.
Please respond within five(5)days of the date of this letter by sending two(2)copies of the above
information in writing. The Express Review Program is a process that requires all parties to participate in
a timely manner.
