Subject: Request for Additional Information
Stormwater Permit No. SW6191004
Multipurpose Training Facility, SOTF
Cumberland County
Dear Mr. Saltsman:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on October 29, 2019. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
1. The drainage area table on Page 3 of the SWU-101 application incorrectly lists the
drainage area to SWM#2 as 42,209 ft2, whereas the calculations show it as 2.215 acres.
Please revise the application form to correct this discrepancy.
2. Please make the following revisions to the Supplement EZ form:
a. Complete the information for the seasonal high water table (Fields 22 & 23).
b. Revise the bottom elevation to reflect the elevation of the subsoil at the bottom of
the stone layer (Field 29).
c. Complete the information for the infiltration trenches (Fields 34-43).
3. The boring location map shows no borings in the areas of the infiltration systems to
determine the seasonal high water table. Please explain how the elevation of the seasonal
high water table was determined in these areas.
4. The infiltration tests should be completed at the final elevation of the subsoil. The
Supplement EZ form indicates that the infiltration tests were completed at the existing
grade of the site, which does not accurately reflect the infiltration rates of the soil at the
excavated elevations.
