We have not received a reply to our previous protest to the
draft effluent limits for our Woodlake S.T.P. We continue to
protest the stricter limits which we understand are the result
of the State classifying the receiving stream as having a 7Q10
and 30Q2 of 0.0 cfs.
We do not agree with the 0.0 cfs determination and would like
to know what actions are required by us to have this classifi-
cation reevaluated.
Sincerely,

SUBJECT: Woodlake MHP's NPDES Permit
No. NC0023299 limit changes for
their new Permit that will become
effective May 1, 1994, Guilford County
It appears that Technical Services must address the
questions about the limits spelled out in the new permit
that may provide treatment and real economic problems for
the subject Permittee. The limits may force other options
on the park owner. The WWTP serves both Woodlake MHP and a
new subdivision now under development by Oakwood Land
Development called Greybridge Subdivision. The WWTP
ownership has been retained by Oakwood Land Development and
the Woodlake MHP has been sold to another owner. Treatment
service for the MHP is provided as part of the purchase
price. It is probable that the investments in these two (2)
developments will be adversely affected by the new limits.

SUBJECT: Draft Permit Comments of Oakwood Land Development Corporation
(NPDES No. NC0023299, Guilford County)
I have reviewed the comments of the Oakwood Land Development Corporation
regarding the draft NPDES permit for Woodlake Mobile Home Park, and offer
the following response:
1. The letter mentions that beginning May 1, 1994, the permit contains
just a daily maximum limit for NH3-N and no monthly average limit. I assume
this is true because NH3-N is limited as a toxicant, and that no monthly
average limit is applicable. If the Company wants, a monthly average NH3-N
limit of 1.0 mg/1 could be added to the permit, but the daily maximum limit
would still need to be met.
2. The permittee states that since their instream monitoring data show
little or no reduction of DO as a result of the plants discharge, they are
adequately protecting the environment and do not need more restrictive
effluent limits. Due to limited access, however, their downstream monitor-
ing site is only 300 feet downstream from their discharge, and is not in the
optimal position to capture the true impact of the discharge. Also, the
facility is currently operating at approximately half of their permitted
wasteflow. While the instream data show that there is currently a minimal
impact of the discharge immediately downstream, it does not necessarily mean
that the stream is adequately protected at design conditions and7Q10 flow.
3. The zero -flow values for the 7Q10 and 30Q2 were not arbitrarily
assigned, but estimated by USGS according to procedure. Technical Support
would be glad to re -assess the wasteload allocation upon receipt of informa-
tion that suggests a positive 7Q10. We would encourage the Company to com-
plete a flow study as they have mentioned, but they should be in contact
with USGS and Technical Support to assure that the study is valid and per-
formed according to standard procedure. The letter indicated that the pond
upstream of the discharge could possibly be used for flow augmentation dur-
ing low flow periods. This may be a possible solution if the facility would
agree to a minimum release requirement. It should be noted, however, that
the pond water would probably not be of high quality during low flow periods
due to high temperatures and little inflow.
4. Current Division policy for discharges to streams with 7Q10=0 and
30Q2=0 requires 1) that an engineering report evaluating alternatives to a
surface water discharge be submitted within 12 months of permit issuance,
and 2) effluent limits reflecting tertiary treatment and protecting against
ammonia toxicity become effective three years after permit issuance. These
requirements should not be changed. If the engineering report sufficiently
shows that there are no feasible discharge alternatives, the limits should
go into effect on May 1, 1994, as currently stated in the permit.
If you have any questions or comments regarding this issue, please feel
free to contact me.

Re: NPDES No. NC0023299
Woodlake Mobile Home Park
Guilford County
Dear Mr. Overcash:
We have received the Division of Environmental Managements April 19th
"Notification of Intent" to reissue our NPDES permit for the Woodlake
Waste Water Treatment Plant. As requested, we have reviewed the draft
permit which was attached and find we have major concerns regarding the
proposed permit and the discharge limit requirements. In fact, it was
quite a shock when we examined the draft permit for its particulars. We
found that the proposed discharge limitation on NH3 as N for the period
beginning may 1, 1994 has a daily maximum but no monthly average for
either the summer or winter portions of the permit. Applying the ratio
obviously employed for the other discharge parameters, this would imply
that a monthly average of .75 mg/1 for summer and .9 mg/1 for winter would
be expected of us. We question the technical feasibility of this degree
of nitrogen removal on a consistent basis. We further question the need
for the low maximum daily limit shown.
We, as a corporation, recognize our responsibilities to protect the
environment. Your regional personnel are aware of the significant
investment that has been made at the Woodlake Waste Water Treatment Plant
over the past year to insure that we accomplish what is expected of us.
However, after reviewing the proposed limits, we feel we have no recourse
but to object to the% proposed permit for the period beginning May 1,
1994. Our primary objection is to the very stringent limitation on the
BOD5 - NH3 respectively. A review of our file data indicates that the
facility has met these limits, stringent though they are. Samples taken
from the receiving stream at the plant indicate little or no reduction in
the dissolved oxygen content of the stream due to the plant's discharge.
To us this would indicate that we are successful in our objective of
protecting the environment. Consequently, we fail to see a need for the
more restrictive limits for these two elements of the permit.
IV/AY 2 1iyJli
We believe that the basis for the proposed limits is faulty. in ,,;
technical staff has arbitrarily assigned 0 cfs flow to the jeceiving
stream, even for the 3OQ2. We do no believe that any credit whatsover was
given for the large body of water 100 feet upstream of the discharge point
which could, if required, be employed to provide flow augmentation during
dry conditions. Further, we have decided to embark on a comprehensive
area watershed survey to determine the area size and general
characteristics of the drainage basin available to the stream which serves
the plant. If our belief is correct, then the wasteload allocation
modelling does not accurately reflect the actual conditions of the stream
and discharge point relationship.
We have detected recently a general mood among some of the public and
their regulators to eliminate the small "package" wastewater treatment
plant. This may be a worthy objective, but until a feasible alternative
is available to our customers, we have to continue to strive, as we have
in the past, to provide them with a cost efficient operation while making
our best effort to protect the environment at the same time. This is not
an easy task, as you well know. Unrealistic and unnecessarily restrictive
effluent limits only complicate the situation for everyone.
Please advise us as to the required coarse of action we need to
undertake since we cannot accept the proposed permit with the limitations
as they are now proposed for the period beginning and following May 1,
1994.

COMMENTS
Per standard Division procedure for discharges to streams with 7Q10=0
and 30Q2=0, recommend removal of discharge as soon as an alternate method
of waste disposal can be found. Instream monitoring requirement may be
dropped when the facility agrees, in writing, to a schedule for removal
of discharge. The existing limits (A) should apply for the first three
years of the permit, after which limits (B) should become effective.
Permit should require the facility to submit an engineering report within
12 months of issuance with plans for compliance. Toxicity test is to
address ammonia toxicity and should be required for the first 3 years
only. Recommend instream monitoring of temperature, DO, fecal coliform,
and conductivity.

CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is ql % (defined as treatment two in the North Carolina procedure
document). -The permit holder shall perform quarterly monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed after thirty days from
issuance of this perrnit.during the months of Feb, May , kug, Nov. . Effluent
sampling for this testing shall be performed at the NPDES permittedfinaleffluent discharge below
all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall becompleteand accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 'Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit.may be re -opened and modified to include altemate monitoring requirements or limits.
NOTE: Failureto achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

SUBJECT: NPDES Permit Conditions for Woodlake Mobile Home Park
NPDES No. NC0023299, Guilford County
WLA Request No. 5593
Woodlake Mobile Home Park discharges to a unnamed tributary to Polecat
Creek at a site where the 7Q10 and 30Q2 are both zero. In accordance to
Division procedure for handling domestic discharges to zero -flow streams,
the facility's limits should change three years after permit issuance (see
WLA for specific conditions).
As part of the implementation of the basin -wide permitting schedule,
this permit will again be renewed in April 1991. It is my understanding
that if the permit were to be issued at this time, it would possibly be for
less than a twelve month period. Therefore, per discussion with Don Safrit,
there is the likelihood that the Division will hold the permit and issue it
next April.
If the permit is held, the WLA is correct as is; the permit should be
drafted in the normal manner. If a one-year permit is issued this year, the
existing limits (A) should apply and the permit should include special con-
ditions requiring an engineering report within twelve months of permit issu-
ance and indicating to the permittee that the effluent limits will be chang-
ing in the near future.
If you have any questions or comments regarding this matter, please con-
tact me.
