Dear Mr. Smith:
On November 6, 2022,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 Chatham Park
Associated Areas(Oldham Tract, Mellott Tract, Grantham Tract, Womble Tract, CPI Parcel 1,
CPI Parcel 2, Clark Tract, CPI Parcel 3, CPI Parcel 4, Townsend Tract) service area.
In accordance with 15A NCAC 02T .0114(f)(2),the Division has evaluated the request, and
based on the data submitted,the Division hereby approves for use by Chatham Park Investors,
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 City of Sanford collection system (WQCS00047).
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).
In accordance with 15A NCAC 02T .0114(f),the Division periodically requires reassessment of
wastewater flow data associated with the collection system or the receiving wastewater treatment
plant as applicable to confirm the suitability of the approved flow reduction value. Chatham Park
Investors,LLC shall submit documented,representative data in accordance with 15A NCAC 02T
.0114(f)(1)(A-H)prior to November 30. 2032. Failure to submit the required data by this date
will result in this flow reduction approval letter becoming null and void. Upon review of the
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
Federal regulations with respect to wastewater collection systems,protection of surface waters,
and/or wastewater treatment.
If you have any questions,please contact Charlie Miller, P.E. at(919) 707-3627 or by email at
