In checking Division records, it appears all of the items in the e-mails below we sent to you back on September 17, 2024
and September 10, 2024 have not been addressed.
I want to be sure you noted all of this additional information and to be sure we at the Division have not missed or
overlooked a submittal of the revised plans, specifications and supporting documents for this permit application package
addressing all of the items.
Please confirm you received the e-mails below and provide an update on the project status, since more than 30 days has
expired from the first review comment e-mail. Once this information is received, I will work to move this project

In addition to comment #2 below regarding the NCEMC / Developer Operational Agreement, I just noticed that the
original Agreement from back in 2015 references the development project name as Alligator Bay, but apparently is now
named The Preserve at Tidewater. Please clarify and provide and updated signed Operational Agreement, if Alligator Bay
Associates, LLC still plans to create a HOA to permanently operate and maintain the low-pressure sewer system pumps
and pressure laterals.
Please let me know if you have any questions. Dale

Subject: Alligator Bay Assoc -The Preserve at Tidewater LPSS WQ0029938 Modification request
A review of the application and supporting documents for the subject application has been completed in accordance
with 15A NCAC 02T .0107. Please provide the additional or revised information for the following comments, in order
for the office to complete the review:
1. The proposed project is for the addition of 18 residential simplex pump stations and associated pressure sewer
laterals to The Preserve at Tidewater LPSS. The additional sewer flowrate requested for the subject permit
application modification is zero (0), since the added flow is to be included in an associated modification request
that is pending for permit number WQ0037781, per the narrative letter included in the permit application
package. That modification proposes the addition of 5,850 GPD based on the addition of 18 residential units
(each 5 bedroom) at a reduced sewer design flowrate of 65 GPD per bedroom or 325 GPD per RDU. The design
flow reduction approval letter for use of 65 GPD per bedroom per RDU was issued to Pluris, LLC, January 11,
2023. Please confirm the subject project is located within the service area of the flow reduction letter provided
and be aware that the approval letter may need to be re -issued to ONWASA, in order to be eligible for use for
this project.
2. The permit you are requesting to modify (WQ0029938, modified previously on March 15, 2023) includes an
NCEMC / Developer Operational Agreement, which states the Alligator Bay HOA will be responsible for
operation, maintenance and repair of the simplex pump stations and pressure laterals. However, the transmittal
letter for this project permit modification application package indicates that the developer (Alligator Bay
Associates, LLC) will be responsible for the installation, ownership, operation and maintenance (O&M) of the
proposed 18 simplex pump stations and laterals. Please clarify as to who will be the responsible party for the
O&M of the proposed 18 simplex pump stations and pressure laterals once constructed and also the previously
permitted simplex pump stations and pressure laterals in this development, if that is not the Alligator Bay HOA.
3. The submitted ASEA does not include an approximate length or the size diameter of the proposed 18 pressure
lateral. It appears from the engineering modeling calculations the size is 1.5 -inch. Please provide the size
diameter and estimated length of the 18 pressure laterals proposed.
4. No anti -flotation calculations appear to be submitted for the typical detail of the simplex sewer pump stations in
the supporting information for the permit application as required. Please provide the signed and sealed
calculations.
5. No pump station emergency storage calculations appear to be submitted as required in support of the indication
on the permit application of 400 gallons of storage is available during a power outage. Please provide the signed
and sealed calculations.
6. The two (2) review comments in the e-mail sent 8/30/2024 and 9/4/2024 regarding existing tributary
connections verses the number of connections eligible for the reduced sewer flowrate of 65 GPD per bedroom
and the change of ownership requirement for permits WQ0037781 and WQ0037696 are still pending and
response is needed.
A response to the above comments is considered required in order to proceed with the review of the application and
issuance of the permit. If a complete response is not received within 30 days, the application and supporting documents
will be returned to you in accordance with 15A NCAC 02T.0107(e)(2).

Please feel free to provide digital copies of these revised documents and supporting information to me via email along
with hardcopies via mail.
Please let me know if you have any questions. Dale
