If Yes , SOC No.
a. Classification: WS-V NSW
b. River Basin and Subbasin No. : 03 03 02
C . Describe receiving stream features and pertinent
downstream uses :
-Please note that the Spring Hope WWTP ' s receiving
stream is the Tar River. ( see map for discharge vs .
WWTP locations).
-This discharge is located upstream from Tar River
Reservoir, a drink water supply for Rocky Mount.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS

b. What is the current permitted capacity of the Waste
Water Treatment facility? 0 .4 MGD
C. Actual treatment capacity of the current facility
(current design capacity) ? 0 . 4MGD
d. Date(s) and construction activities allowed by previous
Authorization to Construct issued in the previous two years :.
N\A
e. Please provide a description of existing or
substantially constructed wastewater treatment facilities :
Bar screen, parshall flume, flow meter, influent pumps , primary
clarifiers , high rate trickling filters , secondary clarifiers,
chlorination, chlorine contact
sludge: Aerobic digester, sludge drying beds
f . Please provide a description of -proposed wastewater
treatment facilities :
NA
g. Possible toxic impacts to surface waters : A m m o nia ,
chlorine, and metals( for both effluent and sludge) are
the likely toxicity concerns for this facility.
h. Pretreatment Program (POTWs only) :
in development approved

C. Landfill : Prior the April 15, 1994 inspection of the
subject WWTP, the sludge from Spring Hope was takensto
the county landfill_ . Due to the RRO' s facility WWTP
inspection, it was determined that Spring Hope no
longer has the Coun_ty' s permission to dispose of
residuals in the landfill . Currently, Spring Hope has
contacted AMSCO (a contractor) about land applying
their sludge.
d. Other disposal/utilization scheme (Specify) :

4 . Alternative Analysis Evaluation: Has the facility evaluated
all of the non-discharge options available . Please provide
regional perspective for each option evaluated.
Spray Irrigation: possible, but unclear if sufficient land
is available
Connection to Regional Sewer System: likely not applicable
(Possibly could connect to Rocky Mount)

5 . - Other Special Items :
PART IV - EVALUATION AND RECOMMENDATIONS
This facility currently does not have a satisfactory sludge
disposal plan. Spring Hope, as per their inspection response
letter, is currently pursuing a residuals contractor.
Therefore, prior permit renewal , Permits and Engineering
should require the town of Spring Hope to submit an acceptable
sludge management plan. Pending approval of the sludge
management plan, the Raleigh Regional Office recommends renewal
of NPDES Permit No. NC 0020061 .
If you have any questionZp11e ' e contact Danny Smith at the RRO.
