Subject: Proposed Authorization to Construct
Town of Rutherfordton Wastewater Treatment Plant

MAY 2 9199i
The Groundwater Section has become aware of the subject proposal to upgrade the existing
wastewater treatment plant from 1 MGD to 3 MGD in order to accommodate additional flow
from a new industry. The proposal includes plans to :abandon an existing basin and to utilize an
existing unlined lagoon as an aeration basin.. The existing NPDES permit will expire on
November 30, 1998. When the application for renewal of the NPDES permit is received, the
Groundwater Section wishes to take that opportunity to comment on the renewal, so that
groundwater monitoring may be incorporated into the NPDES permit. In order to assess the
need for monitoring under an NPDES permit at this facility, the Groundwater Section would like
to require groundwater monitoring as part of the Authorization to Construct so that monitoring
data can be collected between now and November of 1998,
o
In 1985 the Groundwater Section constructed seven (7) monitor wells at the facility as part
of the pollution monitor network. The monitoring data collected from 1985 through 1991 shows
no exceedances of groundwater standards during that time, ,with the exception of periodic
increases in total coliform, iron, and manganese (naturally occurring).
The Groundwater Section wishes to recommend that groundwater monitoring be
stipulated in the Authorization to Construct in the following language:
The three existing monitor wells (upgradient monitor well P79w4 and downgradient monitor
wells P79w2 and P79w5) shall be sampled initially at the start-up or the expanded system and
thereafter every April, August, and December for the following parameters:
TDS
NO3
1
L._lep

Chlorides Ammonia Nitrogen
pH Total Coliforms
Water Level Fecal Coliforms
*VOCs (December only) by Method 6230D
*For VOCs:
Method 6230D (Capillary - Column), "Standard Methods For The Examination of Water and
Wastewater", 17th ed. , 1989
The measurement of water levels must be made prior to sampling for the remaining parameters.
The depth to water in each well shall be measured from the surveyed point on the top of the
casing.
If any volatile organic compounds are detected by Method 6230D, then the Asheville Regional
Office groundwater supervisor (telephone number: [phone]) must be contacted immediately
for further instructions regarding any additional follow-up analyses required. The results of all
initial and follow-up analyses must be submitted simultaneously.
The results of the sampling and analysis must be received on Form GW 59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and
Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on or before the last working
day of the month following the sampling month.
If there are any questions please let me know.

SUBJECT: Groundwater Monitoring Comments
Town of Rutherfordton WWTP
NPDES Permit Number NCO025909
Rutherford County
As part of the Authorization to Construct for the subject
facility, groundwater monitoring is required at the start-up of
the expanded system. I have requested the ORC, Paul Rhodes, to
sample 3 of the monitor wells as soon as possible (prior to
start-up), so that the groundwater monitoring data can be
reviewed prior to coordinating our comments for renewal of the
NPDES permit.
Paul Rhodes indicated that the monitor wells will be sampled in
early December. That data will be reviewed and comments sent to
you as soon as possible.
Please call me at [phone] if you have any comments or
questions.

• It is the Divisions understanding that the proposed interlocking sheet piles between the
equalization basin and aeration basin number 2 and between aeration basin number 1
and aeration basin number 2 will no longer be installed due to budget constraints. The
Division has approved the plans and specifications with the understanding that floating
curtains will be installed in place of the interlocking sheet piles. This authorization to
construct is being issued with the understanding that as -built plans, for the installation
of floating curtains, will be submitted for Division review upon completion.
• The subject facility must perform groundwater monitoring in reference to the
requirements stated below.
The three existing monitoring wells (upgradient monitoring well P79w4 and
downgradient monitoring wells P79w2 and P79w5) shall be sampled initially at the
start-up of the expanded system and thereafter every April, August, and December for
the following parameters:
- Chlorides
- pH
Water Level
- VOCs (December only) by method 6230D
Method 6230D (Capillary Column), "Standard Methods for the Examination
of Water and Wastewater," 17th edition, 1989
- Ammonia Nitrogen
- Total Coliforms
- Fecal Coliforms
The measurement of water levels. must be made prior to sampling for the remaining
parameters. The depth to water in each well shall be measured from the surveyed point
on the top of the casing.
If any volatile organic compounds are detected by Method 6230D, then the Asheville
Regional Office groundwater supervisor (telephone number 704-251-6208) must be
contacted immediately for further instructions 'regarding any additional follow-up
analyses required. The results of all initial and follow-up analyses must be submitted
simultaneously.

sampling month.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO025909 issued March 31, 1997, and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No.

MEMORANDUM
TO. Bob Cheek
THROUGH: Don Link.
FROM Kay Dechantu�
SUBJECT: Groundwater Monitoring Comments'
Proposed Authorization to Construct
Rutherfordton Wastewater Treatment Plant
NPDES Permit NCO025909
Rutherford County
The Town of Rutherfordton has proposed to upgrade their existing
wastewater treatment plant from 1 MGD to 3 MGD. The expansion is
to accommodate additional flow from a new industry. The proposal
includes plans to abandon an existing basin and one existing
unlined lagoon is proposed to be utilized as an aeration basin.
I have been requested to expedite review of this project so that
the authorization to construct may be issued as timely as
possible. The review engineer in the Permits and Engineering
Unit is Jeff Myhra at [phone] ext. 597. Please forward
comments to him as quickly as possible.
The NPDES permit will expire on November 30, 1998. It is
requested that the Groundwater Section have opportunity to review
and comment on the NPDES renewal, so that groundwater monitoring
may be incorporated in the NPDES permit.
In 1985, the Groundwater Section constructed 7 monitor wells as a
part of the pollution monitor network at this facility.
Monitoring data collected by our office from 1985 through 1991
shows no exceedances of groundwater standards with the exception
of periodic increases in total coliform, and iron and manganese
(naturally occuring)
The Asheville Regional Office recommends that groundwater
monitoring be stipulated in the Authorization to Construct. Our
comments are as follows:

Bob Cheek memo
Page 2
May 1, 1997
The existing upgradient monitor well (P79w4) and two
downgradient monitor wells (P79w2 and P79w5) shall be sampled
every April, August, and December for the following parameters:
TDS NO3
Chlorides Ammonia Nitrogen
pfi Total Coliforms
Water Level Fecal Coliforms
VOCs (November only) Method 6230D
If you have any comments or questions, please contact me at (704)
