FROM: Jacquelyn M. Nowe11j
SUBJECT: Modification of Monitoring Frequency for Cyanide
City of Newton
NPDES Permit No. NC0036196
Catawba County
In reference to the August 20th letter from Mr. Dwight Wilson
concerning the subject facility, the Technical Support Branch
recommends that the effluent limit for cyanide remain a condition
of the NPDES permit. This limit cannot be removed, unless, the
City reduces its permitted industrial loading to significant indus-
trial users (SIUs) to a level where a NPDES permit limit is not
required. However, upon review of the effluent data submitted by
the City, we will recommend that the monitoring frequency be revised
from weekly to monthly sampling.

In reference to the letter of August 13,1990 from Mr . George
Everett. I am sending the most current data for cynaide
monitoring. I hope this data will demonstrate to the DEM staff
that the City of Newton's industries do not discharge cynaide and
a limit is not necessary. The city has monthly monitoring on the
effluent discharge for cynaide in place . If any more information
is needed please contact either myself or Danny Sigmon.

FROM: Jacquelyn M. Nowell0
SUBJECT: Meeting with the City of Newton
NPDES Permit No. NC0036196
Catawba County
The Technical Support Branch has the following additional
recommendations for the subject facility's NPDES permit based
on the discussions at the August 7th meeting.
1. The inclusion of an effluent limitation of 19 ug/1 of
toluene with a weekly sampling frequency.
2. Monthly effluent monitoring requirements for mercury and
_'uo_ide. Mercury was previously i iized, however upon
further review, monitoring only will be sufficient.
Fluoride has been added based on updated pretreatment data
submitted by the City.
3. The reevaluation of the weekly monitoring frequency for
cyanide. According to the City, all data indicates the
absence of cyanide in their effluent and in that of the
industrial users. In order for the monitoring frequency
to be changed to monthly sampling, Newton must submit
data supporting this revision. This should include
representative influent and effluent data, the cyanide
removal efficiency of the plant, and information showing
the laboratory's analytical detection level used in their
analyses. The information has been requested by August 22,
1990. If not received, the permit should go forward as
currently drafted.
4. The final recommendation for the chronic toxicity require-
ment should be made by the Environmental Sciences Branch.
A copy of the draft permit is requested prior to renoticing.
Please contact me if there are any questions concerning this
matter.

Dear Mr. French:
I would like to thank you for scheduling the time to come to
Raleigh and discuss the issues concerning the City of Newton. It
is my understanding that there was a thorough discussion of your
main concerns and the meeting was beneficial to everyone. Please
feel free to contact any DEM staff member if further clarification
of these issues is needed.
The following details the actions taken by the Division in
reopening Newton's NPDES permit, including additional information
finalized in the August 7th meeting.
The NPDES permit for Newton was reopened per Section 307 of the
Clean Water Act and Sections 2B .0208 and .0211 of the North Caro-
lina Administrative Code to include effluent limitations for
cadmium, chromium, nickel, lead, cyanide, toluene, and a chronic
toxicity testing requirement based on information regarding the
presence of these substances that was not available at your last
permit renewal. Review of facility self -monitoring data indicate
exceedances of levels necessary to maintain State water quality
criteria. In addition, the City has issued pretreatment permits to
significant industrial users (SIUs) for allocations of all the con-
stituents listed above. In light of these facts, the Division has
determined that effluent limitations for these substances must be
established to ensure protection of the water quality and designated
use of the receiving waters downstream of Newton.
Particular concern was expressed regarding the effluent limit
for cyanide since your data shows no presence of cyanide in your
effluent or in that of your industrial users. However, Newton's
pretreatment headworks data indicated a permitted loading of 0.74
lbs/day with a predicted effluent concentration of 9.9 ug/1. In
order to protect the North Carolina water quality standard of 5
ug/1, it is necessary to assign a limit for this parameter. As dis-
cussed in the meeting, we will reevaluate the weekly monitoring

frequency for cyanide. In order for the monitoring frequency to be
changed to monthly sar.pling, Newton must submit data supporting this
revision. This should include representative influent and effluent
data, the cyanide removal efficiency of your plant, and information
showing the laboratory's analytical detection level used -in the
studies. The information should be submitted along with that
required below by August 22, 1990.
In addition, an effluent limitation of 19 ug/ of toluene and
monthly effluent monitoring for mercury and fluoride will now be
included in your NPDES permit. Mercury was previously limited, how-
ever, after further evaluation only effluent monitoring will be
required. Permit requirements for toluene and fluoride were based
on updated pretreatment data submitted by the City.
Your facility is also required to conduct monthly effluent moni-
toring for zinc, silver, and copper. The State has established
action levels for these pollutants, which are toxic substances which
are not generally bioaccumulative and have variable toxicity to
aquatic life. North Carolina regulation 15A NCAC 2B.0211(b) (4)
states that "if substances ... are determined by the wasteload allo-
cation to be exceeded in receiving water by a discharger under the
specified low flow criterion for toxic substances, the discharger
will be required to monitor the chemical and/or biological effects
of the discharge...".
Finally, the requirement for chronic toxicity testing as a
condition of permit compliance is deemed inappropriate by your City.
Your request to have a modification of the toxicity requirement by
inclusion of a special condition, as presented by Mr. Robert Epting
during the meeting, must be sent in written form to this Division by
August 22, 1990. If this information is not received by this date,
or if upon review the Division determines that the City of Newton is
not eligible for this condition, the permit will be issued with the
toxicity requirements as denoted in the original draft permit.
I hope that all of your questions or concerns have been
addressed. Please feel to contact Mr. Don Safrit or Trevor Clements
at [phone] if any additional infor.-. ion is needed.

MASON FARM WASTEWATER TREATMENT PLANT
J.(1) On a quarterly basis commencing January 1, 1989, and for a
period of one year thereafter, permittee shall conduct chronic
toxicity testing using the procedures outlined in the current or
subsequent versions of the North Carolina Ceriodaphnia chronic
effluent bioassay procedure -- (North Carolina Chronic Bioassay
Procedure, Revised, February, 1987), at an effluent concen-
tration of 93% (defined as treatment two in the North Carolina
Procedure document). Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below
all treatment processes.
All toxicity testing results obtained as a result of this
permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which the test was
performed, using the appropriate.pararneter code. Additionally,
DEM Form AT-1 (original) will be sent to the following address:
Technical Services Branch
North Carolina Division of Environmental Management
P.O. box 27687

Test data shall be complete and accurate and shall include all
supporting chemical/physical measurements performed in associ-
ation with the toxicity tests, as well as all dose/response data.
Total residual chlorine must be measured and reported if employed
for disinfection of waste stream.
Failure to achieve the test conditions as specified in the
cited document, such as minimum control organism survival or
inappropriate environmental controls, shall invalidate the
testing and require retesting. Failure to submit suitable test
results in compliance with the requirements of this Permit shall
constitute a failure of permit conditions, and shall require
retesting.
Should any test data from this monitoring requirement, or
from testing performed by the North Carolina Division of
Environmental Management, indicate chronic toxicity or other
consistent adverse impacts, caused to the receiving stream by the
presence of toxic substances in permitee's effluent, or should
new sources of industrial process wastewater be discharged to the

pefmittee's system, this permit may be reopened and modified to
include alternate monitoring requirements or limitations.
(2) From and after January 1, 1990, permittee shall
continue to comply with the monitoring and testing requirements
prescribed in subpart (1), above, and as the same may be modified
from time to time to meet the requirements set out hereinafter in
this subpart (2) .
Beginning January 1, 1990, the permittee's effluent
discharge shallnot exhibit chronic toxicity, indicated by at
least two consecutive test procedures performed as required
hereunder, and caused by the presence in its effluent of any
"toxic substance" (as defined in Title 15, Subchapter 2B of the
North Carolina Administrative Code). Potential effluent toxicity
shall be determined using the test procedures outlined in the
current or subsequent versions of the North Carolina Ceriodaphnia
chronic effluent bioassay procedure -- (North Carolina Chronic
Bioassay Procedure, Revised, February, 1987), at an effluent
concentration of 93% (defined as treatment two in the North
Carolina Procedure document).
Failure to achieve the test conditions as specified in the
cited document, such as minimum control organism survival or
inappropriate environmental controls, shall invalidate the
testing and require retesting. Failure to submit suitable test
results in compliance with the requirements of this Permit shall
constitute a failure of permit conditions, and shall require
retesting.
Should the test results from any quarterly procedure
required under this monitoring requirement indicate a failure,
permittee shall immediately commence and continue monthly
monitoring and testing until such time that a single test is
passed. Upon passing a subsequent monthly test, the monthly
monitoring requirement hereunder shall revert to the quarterly
requirement.
Should the results of any monitoring and two consecutive
tests required under subpart (2) of this Paragraph J, or from
testing performed by the North Carolina Division of Environmental
Management, indicate the potential for chronic toxicity or other
consistent adver e impacts, caused to the receiving stream by the
presence of any<Rirohibite>toxic substance in permittee's
effluent, or should new sources of industrial process wastewater
be discharged to the permittee's system, this permit may be
reopened and modified to include alternate monitoring
requirements or limitations; or, permittee shall be required to
comply with the provisions of any special order by consent the
North Carolina Division of Environmental Management and permittee
shall execute respecting further testing requirements and/or
whole effluent toxicity limitations. During the period of the
special order by consent and provided the permittee is in
compliance with the terms of the special order by consent,
permittee shall not be deemed to have violated the terms and
conditions of Paragraph J of this permit.

Subject: Chlorine Toxicity
NPDES Permit No. NC0036196
Catawba County
Dear Mr. French:
Chlorine, a widely used wastewater disinfectant for the
treatment of coliform organisms, often remains instream in residual
amounts that may prove to be toxic under critical low stream flow
conditions: In the last decade, EPA assessed the potential adverse
effects of chlorine to the aquatic environment and has taken steps to
reduce the impacts through the development of federal criteria. In
1986, EPA recommended that all states have a chlorine standard by
their next triennial review of water quality standards.
In revising its water quality standards in 1989, North Carolina
developed an action level for chlorine of 17 ug/1 (freshwater classes
only). In addition, the fecal coliform limit was reduced from 1000
colonies/100 ml to 200 colonies/ 100 mi. Under a new DEM procedure,
dechlorination and chlorine limits are now recommended for all new or
expanding dischargers proposing the use of chlorine for effluent
disinfection. The Division is reviewing chlorine levels from all
existing dischargers as part of their !PDES permit renewal process.
Our records indicate that chlorine from your facility's effluent
discharge is considered toxic to the receiving stream under low flow
conditions, i.e., the amount of chlorine discharged causes'a viola-
tion of the instream action level for chlorine (17 ug/1) under 7Q10
conditions (the lowest average daily flow for seven (7) consecutive
days during a ten (10) year period). Action should be taken to
reduce the effluent concentration of chlorine to an acceptable level.
Based on your facility's instream waste concentration of 56%, an
acceptable level of chlorine in your effluent is 30 ug/1. If this
level is not feasible, you should consider dechlorination or alter-
nate methods of disinfection for your facility to ensure that both
chlorine and bacterial limits are met. In addition, if your facility
plans to undertake any phase of construction, dechlorination or
alternate disinfection should be included. However, please note that
an authorization to construct must be obtained from this Division
prior to any alteration to your treatment plant.

The Division is currently reviewing its water quality
regulations pertaining to chlorine. In the future, effluent limits
and/or dechlorination may be required of existing facility's with
chlorine problems. If the chlorine levels in your facility's
effluent remain unchanged, a chlorine limit or a whole effluent
toxicity testing requirement may be added to your permit limitations.
Please feel free to call Mr. Rex Gleason of the Division's
Regional Office at [phone], if you have any questions or com-
ments regarding this issue.

Re: Draft NPDES Permit, City of Newton, N.C.
Dear Mr. Overcash:
I appreciate the opportunity to have talked to you today
about my representation of the City of Newton regarding concerns
they wish to review with the Division arising out of the draft
NPDES permit which would have been issued effective June 15,
1990.
I write to acknowledge our understanding and agreement that
prior to further action by the Division with respect to the
permit, you and other appropriate Division employees will meet
with the engineers and other representatives of the City to
discuss the concerns raised in the engineer's previous
correspondance with you. I have advised the City attorney Mr.
Larry Pitts of our understanding, and I will be in touch with
you when I return to my office during the week of June 18 to
calendar such a meeting at a time convenient for those who need
to get together for this purpose.
I appreciate very much your assistance in this matter.
With kind regards, I remain
Very trulyy

Subject: NPDES Permit No. NC0036196 Proposed Revisions
Dear Dr. Everett:
OFFICE OF THE CITY MANAGER

*ATERvUA1.5'
ACT''�1
Reference is made to subject permit for which public notice was issued on April 19,
1989. In accordance with said notice, the City of Newton hereby expresses opposition
and objection to the issuance of the revised permit and petitions your office to leave in
place those permit provisions which now exist.
Our opposition to revisions reflect the following factors:
1. There has never been any reported evidence to the City as to the basis for or
necessity of the revisions.
2. The use of Chronic Toxicity to judge permit compliance is not appropriate. The test
reportedly does not give consistent results nor do different certified laboratories agree
on "pass/fail" from the same samples.
3. Cyanide and Mercury have been proposed as discharge limits in -spite of the fact that
they have not been found in previous sampling of our effluent.
4. Zinc, Silver, and Copper have been added to our monitoring requirements although
they have not been included in the parameters for which "Discharge limitations" are
proposed.

We request that, if re -issue of subject permit is still deemed necessary by your office,
the matter should receive full hearing in which we are able to present the basis of our
concerns, and that your staff be required to fully substantiate the evidence supporting the
proposed new permit conditions.
