I would like to say yes, but if there are more pressing reviews that were submitted earlier, they will take priority over
this one.

Good morning. The revisions were uploaded to the portal on Friday, and hard copies will go out today. Just confirming
again that we will be able to receive a permit without a second 90 day review period.

Thanks.

Justin,
I was looking over the additional information you provided on October 16, 2023. Everything looks good except for a
few small issues:
Please correct the following:
 Per the Supplement-EZ Form, the invert of the bypass orifice is shown at elevation 634.5 ft. However, the plans
do not appear to show a bypass orifice at this elevation (per the outlet structure detail on sheet C901, the
lowest bypass device appears to be the rim of the outlet structure at elevation 635.0 ft). Please either
including the bypass orifice with invert elevation of 634.5 ft or by revising the design calculations to show the
temporary pool surface elevation at elevation 635.0 ft. Please revise as needed.
The supplement form is correct. Our design is based on the bypass orifice at elevation 634.5. We just overlooked it in
our detail. We will revise.


 Please break the provided stage-storage table down to show the storage volume provided in the sediment
chamber and provided in the sand chamber so the storage volumes provided in the each chamber may be
verified and compliance with Sand Filter MDC 2 may be verified.

We break the provided storage volume down for each chamber in Table 12 of our report. We intentionally place our
stone weir dividing the chambers such that the volumes in each chamber match. Are you looking for something other
than this?


 While not required, it is recommended to leave the surface of the sand layer bare or cover it in gravel. Per the
plans, the surface of the sand layer is shown to be covered with Bermuda sod. Sediment trapped by the sand
filter accumulates on the surface of the sand layer and it is easier to remove this accumulated sediment if
there is no grass on the surface of the sand layer (removal of excess sediment is a required maintenance
activity as specified in the O&M Agreement Form).
We will modify to remove the bermuda sod cover and leave the sand surface exposed.



 While not required, it is recommended to reduce the amount of pervious area draining to the sand filter.
Pervious areas generate fine particles that can cause the sand filter to become clogged quicker, necessitating
more frequent maintenance, which increases the cost of ownership of the sand filter.

I would like to reduce the amount of impervious draining to the sand filter, but unfortunately, there are no practical
alternatives given the site constraints.

The only revisions I see that need to be made are to the plan sheets. We should be able to make those changes, upload
the digitals, and get the hard copies out no later than Monday. If those revisions are satisfactory, do you think we will
be able to get a permit within the next two weeks? We have all our other approvals, but the city will not allow
construction to start without this permit.

Thanks.



Please provide the following:
 1x hard copy & 1x electronic copy of the revised page of the Supplement-EZ Form.
 1x hard copy & 1x electronic copy of the revised page(s) of the calculations.
 1x hard copy (2x hard copies for plan sheets) & 1x electronic copy of any other items needed to address these
comments.
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.
3

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. The quickness of the next review for this project is dependent on
reviewer availability.
Let me know if you have any questions.

Good Morning,

We received your post-construction stormwater permit application for the subject project on 10/13/23. Reviews
under the Standard permitting process can take up to 90 calendar days to complete. You can see where this project
stands in the review queue by emailing [e-mail] (We have an autoreply set up that has the
review queue on it). 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. YOU MUST CLICK ON THE “ADD ANOTHER POST-
CONSTRUCTION FILE UPLOAD” TO ADD ADDITIONAL FILE TYPES TO THE SUBMISSION. Merely changing the file type
dropdown as you upload the various files (without adding additional file uploads) will upload all of the files as the last
file type selected, the submission will get flagged during review, and you will need to resubmit the files. 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. NOTE: We do not require and we discourage the upload/submission of extraneous plan
sheets (such as lighting plans, utility plans, striping plans, sight distance plans, etc…) as these files are not needed for
review.

Please type in permit #: SW5231002

This project will be reviewed by Jim Farkas, if you have any questions, please contact them at
[e-mail] or at 919-707-3646.

Thank you,

Hi Justin,

On your application, the total impervious surface area is listed as 23,502 sf (approx.. 0.54 ac). Please see the attached

Can you please clarify how our %impervious is calculated incorrectly? The 1.65 acre site contains 0.63 acres of
impervious = 38%.

Thanks.
