Subject: Request for Additional Information
Stormwater Permit No. SW1190301

Dear Mr. Buie:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on March 14, 2019. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
l . The applicant signed the Property Owner Authorization section of the application form,
not the Applicant's Certification. The Property Owner Authorization is only for
applications where the applicant does not own the property. The Applicant's Certification
is required for all applications. Please resubmit an application with this section signed
and notarized.
2. Is there any intention to reuse a portion of the water in the large cisterns below the
parking lot? Detaining and discharging runoff directly to a vegetated setback does not
meet the intent of rainwater harvesting.
3. Please submit a USGS map identifying the project location.
4. Please submit a signed and sealed copy of Page 1 of the Supplement EZ form.
5. The bioretention cells must be planted with trees, herbaceous plants, or sod. Mulch alone
is not sufficient to meet this requirement.
6. The calculations for Bioretention Cell #6 only count the new impervious area in the
runoff calculations. Runoff from existing BUA can be bypassed; however, if existing

BUA is flowing through an SCM the SCM must be designed to treat the entire
contributing area.
7. The geotechnical report shows that the seasonal high water table is either above the
bottom of the bioretention cells or very close. The presence of wetlands in close
proximity to the bioretention cells also indicates that the seasonal high water table is
likely very high. According to Bioretention MDC 1, the seasonal high water table must
be at least two feet below the bottom of the bioretention media.
8. Sheet C-301 indicates an area as "Proposed Fuel." Please explain what this area will be
used for.
9. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other
documents. Pdfs must be uploaded using the form at:
hqps:Hedocs.deg.nc.gov/Forins/SW ProjectSubmittal
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to June 13, 2019, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal
of all required items, including the application fee. Please reference the State assigned project
number SW1190301 on all correspondence.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
If you have any questions concerning this matter please feel free to contact me at
