Subject:
Dear Mr. Nelson:
Imposition of Sewer Line Moratorium
Demonstration of Future Wastewater Treatment
Capacities
NPDES Permit NC0020389
Town of Benson — Benson WWTP
Johnston County
15A NCAC 02T .0118, "Demonstration of Future Wastewater Treatment Capacities," was adopted by the
Environmental Management Commission to ensure that wastewater treatment systems owned or operated by
municipalities, counties, sanitary districts or public utilities do not exceed their hydraulic treatment capacities.
This Rule specifies that no permits for sewer line extensions will be issued by the Division of Water Resources to
facilities exceeding 80% of their hydraulic treatment capacity unless specific evaluations of future wastewater
treatment needs have been completed.
A review of your self -monitoring reports has indicated flow at the subject facility exceeded the 80% threshold for
calendar year 2020. The average flow calculated for this period was 1.5646 MGD, and represented 82.3% of the
current treatment capacity. Therefore, we will be unable to approve any further sewer line extensions for this
facility until such time as you have complied with the requirements contained in the Rule.
In order to attain compliance with the Rule, you must submit an approvable engineering evaluation of future
wastewater treatment needs. This evaluation must outline specific plans for system expansion and include the
sources of funding for the expansion. If future expansion is not proposed, a detailed justification must be made
based on past growth records and future growth projections and, as appropriate, shall include conservation plans
or other specific measures to achieve waste flow reductions.

Provision For Sewer Line Approvals While On Moratorium
Per the terms of NCAC 02T .0118 (3), the Director may, on a case -by -case basis, allow permits to be issued to
facilities exceeding the 80 percent loading rate if: 1) the additional flow will not cause the facility to exceed its
permitted hydraulic capacity, 2) the facility is in compliance with all other permit limitations and requirements
and 3) it is demonstrated that adequate progress is being made in developing the required engineering evaluations
or plans and specifications. Delegation for approval and denial of such requests has been given to the Water
Quality Regional Operations Supervisor for the Raleigh Region. If you wish to ask for a waiver of the
moratorium per this provision of the rule, please send all required information in support of your request to the
Raleigh Regional Office.
Any plans and specifications for expansion should be submitted to the Division of Water Infrastructure.
We look forward to working with you on development of plans to meet your future wastewater treatment needs.
If you have any questions regarding this matter, please contact the Water Quality Regional Operations staff of our
Raleigh Regional Office at 919-791-4200. You can also contact Sydney Carpenter of the Compliance &
Expedited Permitting Unit at 919-707-3712 or by e-mail at sydney.carpenter@ncdenr.gov.

15A NCAC 02T .0118 DEMONSTRATION OF FUTURE WASTEWATER TREATMENT CAPACITIES
No permits for sewer line extensions shall be issued to wastewater treatment systems owned or operated by
municipalities, counties, sanitary districts, or public utilities unless they meet the following requirements:
(1) Prior to exceeding 80 percent of the system's permitted hydraulic capacity (based on the average
flow during the last calendar year), the permittee shall submit an engineering evaluation of their
future wastewater treatment, utilization, and disposal needs. This evaluation shall outline plans for
meeting future wastewater treatment, utilization, or disposal needs by either expansion of the
existing system, elimination or reduction of extraneous flows, or water conservation and shall
include the source of funding for the improvements. If expansion is not proposed or is proposed
for a later date, a justification shall be made that wastewater treatment needs will be met based on
past growth records and future growth projections and, as appropriate, shall include conservation
plans or other measures to achieve waste flow reductions.
(2) Prior to exceeding 90 percent of the system's permitted hydraulic capacity (based on the average
flow during the last calendar year), the permittee shall obtain all permits needed for the expansion
of the wastewater treatment, utilization, or disposal system and, if construction is needed, submit
final plans and specifications for expansion, including a construction schedule. If expansion is not
proposed or is proposed for a later date, a justification shall be made that wastewater treatment
needs will be met based on past growth records and future growth projections and, as appropriate,
shall include conservation plans or other specific measures to achieve waste flow reductions.
(3) The Director shall allow permits to be issued to facilities that are exceeding the 80 percent or 90
percent disposal capacity if the additional flow is not projected to result in the facility exceeding
its permitted hydraulic capacity, the facility is in compliance with all other permit limitations and
requirements, and adequate progress is being made in developing the required engineering
evaluations or plans and specifications. In determining the adequacy of the progress, the Director
shall consider the projected flows, the complexity and scope of the work to be completed, and any
projected environmental impacts.
