John,

I was looking over the additional information you provided on April 4, 2023. Everything looks good except for a few small
issues:

Please correct the following:
- Prior Comment 1d – There still appears to be an issue with the drawdown calculations, The starting water
elevation is shown as 193.36’ which does not correspond to the temporary pool surface elevation (193.7’) which
impacts the driving head used to determine the rate of drawdown of the design volume. Please ensure that the
starting water elevation (and by extension, driving head and drawdown rate) is based on the temporary pool
surface elevation (193.7’ per the invert of the bypass mechanism on the outlet structure). NOTE: While not
required per the MDC, it is recommended to size the drawdown orifice so that both the design volume (21,695
cf) and minimum required treatment volume (13,651 cf) drawdown within the required 2-5 day window
(reducing the size of the drawdown orifice from 2.5” to 2.0” should address this). Please revise as needed.

Please provide the following:
- 1x hard copy & 1x electronic copy of the revised calculations.
- 1x hard copy & 1x electronic copy of the revised Supplement-EZ Form Pages.
- 2x hard copies & 1x electronic copy of the revised plan sheets (if applicable).
- 1x hard copy & 1x electronic copy of any other items needed to address this issue.

Hard copies should be mailed to me at the following address:
For FedEx/UPS:
Jim Farkas
512 N. Salisbury Street, Office 640M
Raleigh, NC 27604

For USPS:
Jim Farkas
1612 Mail Service Center
Raleigh, NC 27699-1612

Hand Delivery:
Please reach out to me prior to hand delivering a submission to make sure that I (or someone else in my group)
will be able to receive the submission. Do not leave the package in the foyer with the security guard.

NOTE: Hard copies should not be sent to a Regional Office. Doing so will delay the review process and the
submission package may be lost while being sent from the Regional Office to me in the Central Office.

Electronic copies should be uploaded at the following location:
https://edocs.deq.nc.gov/Forms/SW-Supplemental-Upload

Since these are really minor things, once I get the hard copies, anything else that may have changed from addressing
these issues, and the documents are uploaded to Laserfiche (Provided everything is still in order), we can issue the
permit without doing another formal review.

Let me know if you have any questions.

Good Morning,
The Division of Energy, Mineral and Land Resources (DEMLR), received additional information for a Stormwater
th
Management Permit Application for the subject project on December 6, 2022. A review of that information has
determined that the application is not complete. Attached is a letter describing the items that need to be submitted. If
you have any questions, please feel free to contact me. My contact information is listed below.
Thank you,

Good afternoon,

We received your post-construction stormwater permit application for the above mentioned project on 12/6/2022.
Reviews under the standard permitting process generally take 75 calendar days, but can take up to 90 calendar days per
statute (our other reviewer, Corey Anen, no longer works for the State, so this review may exceed 75 days). Please
upload all documents that you mailed into our office through the link provided below. Be sure to choose the Central
Office as the Primary Contact office.

https://edocs.deq.nc.gov/Forms/SW-Supplemental-Upload

IMPORTANT NOTE: Please ensure that each file is uploaded under its appropriate file type. Additional file types can be
entered into the electronic form by clicking on the “Add Another Post-Construction File Upload” link directly below the
“State Stormwater Information Uploads” section of the form. Please do not upload entire plan sets through this form,
but rather upload the relevant individual sheets under the appropriate file type. Selecting the correct file type ensures
that the files are properly named in the electronic repository and it helps expedite the review process.

Please type in permit #: SW6221201

If you have any questions, please contact Jim Farkas [e-mail] 919-707-3646.

Thank you,
