Good morning, Brittany,
We had discussed that one of our clients—COC: NCG030727 -added a retention pond onsite which in turn changed the
drainage areas. Initially the site had SDOs 001, 002 and 003. However, they now have SDOs 001, 002 and 004. Can you
assist with updating Kelly Pipe's SDOs in the NCDEQ system?See table below for details:

Drainage Estimated
Outfall Area SDO Coordinates
Impervious (deg, min, sec)
(Acres)
SDO 001 1.02 100% N 35' 06' 50.3";
W 80' 54' 52.6"
SDO 002 0.35 100% N 35' 06' 50.9";
W 80' 54' 52.0"
SDO 003 is obsolete due to new BMP-retention
SDO 003 basin with sand filter. SDO 003's drainage area is
now captured by the retention basin, i.e., SDO 004.
SDO 004 1.20 64% N 35' 06' 53.0";
W80' 54' 51.0"
Also, I have attached this site's COC. Can you assist with correcting the 4 typos circled in red?We are currently updating
their SWPPP to include the new BMP and will be including the COC in one of the Appendices.
If you need any additional information, please let me know.
Best,
Mandy Tzannis

Hi Brittany,
Thank you for your response. When the number of outfalls is finalized for this site, I will reach out to you go get them
updated in the state's portal.

Hi Mandy,
To answer your previous question, if you cannot submit a report for the newly created outfall then I would submit it via
the DMR Upload Form (The "Old fashioned way of submitting DMRs.)
If you provide me the COC number for the site, I can make sure the outfalls are up to date since I can add and remove
outfalls.

Hello Brittany,

I was wondering if you've had a chance to look into this matter. It might be more effective to have a discussion via a
Teams call. Could you please inform me of your availability, and I can send you an invitation? It's crucial that we address
this issue promptly to ensure our client stays in compliance with the permit.
Warm regards,
Mandy Tzannis

Good morning, Brittany,
Given the necessity to introduce an additional outfall (involving the discharge from the pond), how should the site go
about reporting data in the eDMR system for the newly created outfall 004, considering that it currently does not exist in
the NCDEQ system for this site? Furthermore, in the case of outfalls 002 and 003 (which are now considered obsolete
since the pond will be managing the runoff from their drainage areas), what steps should be taken in eDMR to ensure
that no NOVs (Notices of Violation) are generated?

Good afternoon Mandy,
From what you've described of the different outfalls, it sounds like you may only need 1 outfall to be covered. If the
pond ever discharges stormwater, then that would be considered it's own outfall.
But Bethany is correct, we would not be able to remove the extra outfalls in our system due to having monitoring data.
If the pond does not discharge stormwater, then I would keep monitoring at outfall 1 and do not report for the other
outfalls until the renewal of the General Permit.

Hi, Mandy,
I'm putting you in touch with our General Permits coordinator, Brittany Cook, for further assistance. Brittany, please see
the questions below.
If the permittee is reporting through eDMR already, the outfalls will need to stay to house the historical data reported,
but they won't need to report data for those the remainder of the term (and they can disregard any warnings the
system may give them about that).The outfalls that have become "internal" can then be removed at the next permit
cycle.

Bethany good morning,
I hope you are doing well! I have a few questions I am hoping you can assist with.
We are currently working with an industrial client located in Mecklenburg County.They have recently added a detention
pond/sand filter to their site in order to comply with local regulations.Their current Certificate of Coverage (COC)
encompasses the original three outfalls. However, this newly constructed pond now captures a portion of SDO 001 and
the entirety of SDOs 002 and 003. Our plan is to update their Stormwater Pollution Prevention Plan (SWPPP)to
incorporate this new Best Management Practice (BMP), and we will also be reevaluating the drainage areas for the
outfalls.
4

Our main questions are as follows:
1. Will this necessitate the submission of a new Notice of Intent(NOI)to update the outfalls?
2. Should we consider voiding or canceling SDOs 002 and 003, given that the new pond now manages the runoff
from their respective drainage areas?Would it be appropriate to designate the pond's outfall as "SDO 004"?
I appreciate any information you can provide on this matter.
Best,
Mandy Tzannis
