Subject: Speculative Limits Request
Town of Cherryville WWTP
NPDES Permit No. NC0044440
Gaston County
Dear Ms. Hovis:
The Division of Water Quality has completed its evaluation of your request
for speculative limits for Town of Cherryville's wastewater treatment facility
discharging to the Indian Creek. You specifically requested speculative limits for
a wasteflow of 4.0 MGD.
Based on available information, the tentative effluent limitations are as
follows for a 4.0 MGD discharge at this location:
Summer Winter
GODS (mg/L) 30 30
NH3-N (mg/L) 1.8 5.9
DO (mg/L) 5 5
TSS (mg/L) 30 30
Fecal Coliform (#/100 mi) 200 200
pH (SU) 6-9 6-9
Chlorine (µg/L) (daily max) 28 28
Copper (µg/L) (daily max) Quarterly Monitoring
Zinc (µg/L) (daily max) Quarterly Monitoring
Cadmium (µg/L) (daily max) Quarterly Monitoring
Nickel (µg/L) (daily max) Quarterly Monitoring
Lead (µg/L) (daily max) Quarterly Monitoring
Cyanide (µg/L) (daily max) Quarterly Monitoring
Chromium (µg/L) (daily max) Quarterly Monitoring
The specified ammonia limits are necessary to protect the Indian Creek
from toxic effects. Following current EPA guidance, DWQ is using instream
ammonia criteria of 1 mg/L during the summer and 1.8 mg/L during the winter,
under 7Q10 flow conditions. The 7Q10 estimate used by the DWQ for this
location on the Indian Creek is 6.1 cfs.
This speculative analysis includes monitoring requirements for metals or
other toxicant parameters included in the current permit. If an NDPES permit is
requested, a new evaluation of the constituents present in the discharge would be

necessary. The instream waste concentration (IWC) at which limits for toxic
substances will be calculated is 50% for a 4.0 MGD discharge. The facility will
be required to meet a whole effluent toxicity test limit. A chronic (Ceriodaphnia)
test must be performed quarterly with a pass/fail limit at a test concentration of
50%.
Under current DWQ procedure, dechlorination and chlorine limits are
recommended for all new or expanding dischargers proposing the use of chlorine
for disinfection. An acceptable level of residual chlorine in the effluent of this
plant in order to protect against acute toxicity is 28 µg/L. If the facility utilizes
UV disinfection with a backup chlorine system, the chlorine limit will apply only
when the backup chlorine disinfection system is in operation.
Any future permits will include monitoring requirements for the limited
parameters. The permit will also require monitoring for parameters without
specified effluent limitations, and monitoring of both the effluent and the
receiving stream, as does the current permit. Instream monitoring requirements
will be modified to reflect applicable monitoring agreements with the Division.
Additional Considerations
The speculative limits presented here are based on our understanding of
the proposal and of present environmental conditions. Over time these conditions
may change or additional information may become available. Please be aware
that response to this request for speculative limits does not guarantee that the
Division of Water Quality will issue an NPDES permit for an expansion to a 4.0
MGD discharge to the location. Nor can we guarantee that the effluent
limitations and other requirements included in any permit will be exactly as
presented here. Final decisions on these matters will be made only after the
Division receives and evaluates a formal permit application for the proposed
discharge.
Environmental Assessments of New Proiects and Expansions
The environmental impacts of the proposed discharge must be evaluated
prior to the filing of a permit application. Anyone proposing to construct new or
expanded waste treatment facilities using public funds or public (state) lands
must first prepare an environmental assessment (EA) when wastewater flows (1)
equal or exceed 0.5 MGD or (2) exceed one-third of the 7Q10 flow of the
receiving stream. The Division will not accept a permit application for a project
requiring an environmental assessment until the Division has approved the EA
and sent a Finding of No Significant Impact (FONSI) to the state Clearinghouse
for review and comment.
The Environmental Assessment should contain a clear justification for
the flow. It should provide a comprehensive analysis of potential alternatives to
relocation, including a thorough evaluation of non -discharge alternatives.
Nondischarge alternatives to relocation --such as spray irrigation, water
conservation, and inflow and infiltration reduction --are considered to be
environmentally preferable to a surface water discharge.
2

In accordance with the North Carolina General Statutes, the preferred
alternative must be the practicable waste treatment and disposal alternative with
the least adverse impact on the environment is required to be implemented. If the
EA demonstrates that the project may result in a significant adverse effect on the
quality of the environment, you must then prepare an Environmental Impact
Statement. Gloria Putnam of the Water Quality Planning Branch can provide
additional information regarding the requirements of the N.C. Environmental
Policy Act. You can contact Ms. Putnam directly at [phone], ext. 567.
The above limits are to assist you in your planning and engineering
analyses and are speculative. Please note that prior to any DWQ approval of the
expansion, you will need to demonstrate compliance with the speculative limits.
Final NDPES effluent limitations will be determined after a formal permit
application has been submitted to the Division. If there are any additional
questions concerning this matter, please feel free to contact either Adugna
Kebede (ext. 515) or me (ext. 517) at [phone].
