Dear Mr. Gibson:
This letter is to inform you that the Division has finalized its review and the comment period is
now closed for NPDES permit NC0028975. A final copy of the permit is attached to this letter for your
records. `This permit is issued pursuant to the requirements of the North Carolina General Statute 143-
215.1 and the Memorandum of Agreement between North Carolina and the US Environmental
Protection Agency dated December 6, 1983.
The following list-has been included to outline the changes that were addressed in the draft
permit. These,changes remain unchanged in the final permit:
➢ A summer and winter limit for ammonia has been included in the permit renewal. These
limits will become effective exactly one year from the effective date of the final permit. For
the first year, the facility is only required to monitor for ammonia. In addition, the
monitoring frequency has changed from 2/m6nth to weekly. This change is consistent with
the requirements as specified in the North Carolina Administrative Code Section 15A NCAC
2B.0500 for class II facilities.
➢ The permit expiration date has been changed. The permit renewal will expire on July 31,
2003. The expiration dates have been revised so that an equal number of permit renewals
will come in at any one time. This change will allow the Division to issue permits more
efficiently.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of

Re; City of Saluda Permit renewal.
NC0.02.8975 Polk County
Per our discussion today, the .A.RO is recommending that the
City of Saluda' s permit be, renewed, based on the following
information.
1 . A chrQnic ' (full range) toxicity test performed by the State
on the WWTV, s effluent in October revealed toxicity due to
chlorine disinfection.
2. Based can discussions with the operator and City mayor, the
City has elected to have ammonia limits 'in lieu of toxicity
limits.
2 . Based. on past DM'R data, it !a evident that the WWTP would
not be able to most the proposed ammonia limits There-
fore, it is recommended that the.. permit be issued with two
mor�itnrircr_.Aimits nacres'.
a. The f ixs�t nacre would require` "monitoring only"
for effluent ammonia' (no ammonia limits) . This
option, offers a schedule of. compliance that would allow
,the City on.e year to furth6r monitor and mare
operational changes as needed to meet the proposed
ammonia limits.
b. The second e; would contain the proposed monitoring
requirements and limits for summer and winter.
r
4. Please proceed to public notice with the proposed draft
permit which reflects -the above recommended changes.
If we Can be of assistance,, please contact us. Thank you
for your attention to this matter.

Re : City of Saluda
NCO028975
Permit Renewal
Last week I called Jeff Myhra and left a message requesting that
Saluda' s draft permit be held from the scheduled Public Notice—.,
date of October 7, 1998 .
The draft permit includes limits for ammonia (2 .4 summer and 5 . 4
winter) . The current permit does not have any limits for
ammonia. A review of the previous 12 months of DMR data
indicates that the facility will NOT be able to consistently meet
the draft limits .
Because of past fecal coliform violations and short detention
time in the chlorine contact chamber, the wastewater is currently
being chlorinated at a higher than normal rate. This raises the
question as to whether chronic toxicity tests could be passed by
the facility. It is extremely doubtful .
As you know, the City of Saluda in currently under a DOJ Consent
Order because of an American Canoe Association third-party
lawsuit . The City has been in compliance for the past 10 months
and has 8 more months of continuous compliance to achieve to get
out from under this decree and fines .
The City has made tremendous strides toward achieving and
maintaining compliance . To impose limits for parameters that we
already know that the facility will be unable to meet under
present conditions would not be prudent .
We are in the process of discussing the ammonia vs . toxicity
issue and necessary improvements to the treatment process with
the mayor, engineer and ORC.
We have scheduled a full range (IWC 36%) chronic toxicity test
for week the week of October 26-30th. Please let us know if
delaying this permit renewal will be a problem.
