Brad,

I was looking over the additional information you provided on 11/30/2021. Everything looks good except for a few small
issues:

Please correct the following:
- Original Comment 4 (Prior Comment 1) – The project percent impervious area appears to be calculated
incorrectly in Section IV, 8 of the Application. The total impervious area value used in the calculation should be
the total impervious area located within the project area (1,282,035 sf or 29.43 ac) not the total amount of
impervious area located within the drainage area to the wet pond (1,296,852 sf or 29.77 ac). This value should
match Line 18 of the Entire Site Column on the Drainage Areas Page of the Supplement-EZ Form.
- Original Comment 20 (Prior Comment 3) – Please provide an original signed copy of the O&M Agreement. You
will also need to revise the design summary page of this form to match the information in the latest submission.
- Prior Comment 7 – There is still a discrepancy between the drainage area information shown in the calculations
and the value shown in the Application/Supplement-EZ Form. For example, the water quality calculations page
shows the drainage area to the SCM as 39.20 ac (39.22 ac in the Application/Supplement-EZ Form), the
impervious are within the drainage area as 29.56 ac (29.77 ac in the Application/Supplement-EZ Form), and the
design volume as 130,687 cf (104,471 cf in the Application/Supplement-EZ Form). Please revise as needed.
- Please correct the following issues with the Wet Pond Page of the Supplement-EZ Form:
o Line 34 – The cleanout depth of the forebay is the distance from the permanent pool elevation (764.0)
to the top of the sediment storage zone (759.0) expressed in inches (764.0 – 759.0 = 5’ = 60”).
o Line 43 – The depth of the forebay at the entrance is the distance from the permanent pool elevation
(764.0) to the excavated bottom of the forebay near the entrance (758.0) expressed in inches (764.0 –
758.0 = 6’ = 72”).
o Line 44 – The depth of the forebay at the exit is the distance from the permanent pool elevation (764.0)
to the excavated bottom of the forebay near the exit (758.5) expressed in inches (764.0 – 758.5 = 5.5’ =
66”).
o Line 8* – Pond parts 2-4 appear to have emergency spillways which would qualify as a type of
overflow/bypass.
o Line 54* – The pond detail sheets include a planting plan for the wet pond

*I missed these items on the prior review.

Please provide the following:
- 1x hard copy and 1x electronic copy of the revised page of the Application.
- 1x original, signed, hard copy of the O&M Agreement Form and updated design summary page.
- 1x hard copy and 1x electronic copy of the revised calculations.
- 1x hard copy and 1x electronic copy of the revised Supplement-EZ Form page.
- 1x hard copy (2x hard copies for plan sheets) and 1x electronic copy of anything else needed to address the
comments.

Hard copies should be mailed to me at the following address:

For USPS:

Raleigh, NC 27699-1612

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 30-45 day review.

Let me know if you have any questions.
