Jody and Bill,
The project review comments e-mail below I just sent out bounced back for both of you all, so I'm sending back to
you both with corrected e-mail addresses.
My apologies to both of you for not catching this earlier and correcting your addresses before sending out the e-
mail. Thanks, Dale.

Subject: Brunswick County - The Tides at Oceanlsle Beach LPSS extension permit application WQ0045586
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 Division to complete the review:
1. The ASEA indicates a proposed sewer flow rate on page 2 of 5, line #8 of 10,500 GPD based on 50 lots at 210
GPD per residence for 3 bedroom homes as indicated. This equates to a proposed flowrate of 70 GPD per
bedroom per home. Line #7 of the same page indicates a reduced sewer flowrate has been approved by the
Division for this permittee facility, but no copy of the approval letter from the Division appears to be included.
Please provide a copy of the approval letter, as required, or a revised application.
2. The ASEA indicates 360 gallons of emergency storage is provided on page 3 of 5, line #4 in each simplex pump
station wetwell, but no calculations are included in the supporting documents confirming this amount of
storage. Please provide.
3. The project narrative and the overall engineering site plans included in the project submittal reference a
downstream sewer pump station, but the FTSE does not include an evaluation of the pump station and if there is
sufficient capacity to serve the 50 lots served by the LPSS. Please provide a revised FTSE that includes the
evaluation of this pump station.
4. The project engineering plan and profile sheets submitted include some proposed 8-inch gravity sewer, as well
as the proposed LPSS wastewater collection system. How is the gravity sewer portion of this project being
permitted?
5. Sheets C4.27 and C4.3 of the engineering plan and profile sheet appear to indicate fire hydrant assemblies and
the pressure sewer blow -off assemblies that are located adjacent to each other in the two (2) cul-de-sacs of
Street "M". Please verify and label that a minimum horizontal separation of 10 feet will be provided between
these utilities.
6. The engineering plans on sheet C6.8 in the simplex pump station detail have a reference to anti -flotation
requirements of Brunswick County, but no specifics provisions and no calculations are provided, as required in
ASEA instructions. Please provide anti -flotation calculations for the proposed simplex pump stations.
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
