instream turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause
turbidity to increase in the receiving stream. If effluent turbidity exceeds 50 NTU. weekly instream
monitoring shall be required until such time as it is shown that effluent turbidity is consistently less than
50 NTU.
All samples must be collected from a typical discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
A. (2.) Nutrient Reduction Requirement
The Tar -Pamlico Nutrient Sensitive Waters (NSW) Implementation Strategy requires a total reduction

RE: Renewal Application of NPDES Permit NCO082139
Greenville Utilities Commission

Dear Mr. Weaver:
SEP 0 1 Sccn
p '.`1T oouRCE BRANCH
By way of this submittal the Greenville Utilities Commission is requesting renewal
of the subject permit.
Enclosed please find an original and (2) two copies of the NPDES permit
application (short form A), an authorization letter and the sludge management
plan for this facility.
There have been no changes to the facility since the issuance of the last permit.
However, construction of a plant expansion and upgrade are currently in the
beginning stages. The expansion project will increase the treatment capacity
from 15.0 mgd to 22.5 mgd and will include the addition of two (2) sedimentation
basins and three (3) filters.
The upgrade will include the addition of ozone facilities, chloramination feed
equipment, Potassium Permanganate feed equipment ant the addition of sludge
removal equipment.
As a result of the increased waste water from additional filters and sludge
removal equipment the wastewater volume discharged is projected to be in the
0.5 mgd to 0.99 mgd range. The previous application specified a 0.5 mgd flow.

GREEENVILLE UTILITIES COMMISSION
WATER TREATMENT PLANT SLUDGE MANAGEMENT PLAN
Currently sludge from the water treatment process is directly discharged into an
abandoned sand mining pit located on the plant site. Once in the pittlagoon the
sludge solids settle and the excess water is discharged to the river. The lagoon
is approximately 2000 ft. x 500 ft. and has an average depth of 7 ft. The distance
between the lagoon inlet piping and the discharge is approximately 1700 ft.
Once the lagoon reaches capacity, which is expected to be within the next ten
years, the lagoon is projected to be replaced with a sludge handling facility.
The construction of this facility is currently in the fourth year of the 1999 GUC
Five Year Capital Outlay Plan.
