Dear Mr. Thompson:

S. JAY ZWWRMAN
Director
On August 1, 2017, the Division of Water Resources (Division) received an adjusted daily sewage flow
rate (flow reduction) request that would apply to all permitted but not yet tributary residential
connections and all future residential connections within The Cape WWTP service area.
In accordance with 15A NCAC 02T .0114(f)(2), the Division has evaluated the request and based on the
data submitted and the Division of Water and Infrastructure (DWI) guidance, the Division hereby approves
for use by The Cape WWTP 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 120 gallons per day.
• Each additional bedroom above two bedrooms shall increase the volume by 60 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
Cape collection system (WQCS00240).
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 statues, 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 NPDES Permit for the treatment facility or exceed the capacity of
the sewers downstream of any new sewer extension or service connection(s).

and/or modifying the flow reduction as allowed by the laws, rules, and regulations contained in 15A NCAC
