Dear Mr. McMillan:
On April 14,2021, the Division of Water Resources(Division)received a request for an adjusted
daily sewage flow rate(flow reduction)that would apply to all permitted but not yet tributary
residential connections and all future residential connections within the Stateside WWTF service
area. Additional information was requested by the Division and was received on April 4, 2022
and June 1,2022.
In accordance with 15A NCAC 02T .0114(0(2),the Division has evaluated the request, and
based on the data submitted, the Division hereby approves for use by the Old North State Water
Co.,LLC an adjusted daily sewage design flow rate with the following conditions:
• The flow reduction is applicable to residential single-family dwellings only.
• The minimum flow for 1- and 2-bedroom dwellings shall be 130 gallons per day.
• Each additional bedroom above two bedrooms shall increase the volume by 65 gallons
per day per bedroom.
• This flow reduction shall not apply to sewer extension applications and/or permits for any
other public or private organizations whose wastewater flows are or might become
tributary to the Stateside WWTF(WQ0035809).
Future sewer extension applications should be made using the flow reduction amount stated
above. All other aspects of the permitting process remain unchanged, and all applications must
be in compliance with the statutes,rules, regulations and minimum design criteria as certified by
the owner and engineer.
Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater
flows exceed the effluent limits defined in the permit for the treatment facility or exceed the
capacity of the sewers downstream of any new sewer extension or service connection(s).

data,the Division shall either reapprove,modify or not grant reapproval for the previously
approved flow reduction value.
The granting of this flow reduction does not prohibit the Division from reopening,revoking,
reissuing and/or modifying the flow reduction as allowed by the laws,rules,and regulations
contained in 15A NCAC 02T,NCGS 143-215.1,or as needed to address changes in State and/or
