Dear Mr. Baker:
In accordance with your application for discharge permit received on June 25, 1992, we
are forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to
the requirements of 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 responses are offered to your letter dated February 15, 1993 and
modifications to the permit have been made as discussed in the meeting held to resolve the
issues:
1. The location of the plant has been corrected on the cover sheet to the permit.
2. Residual Chlorine: Total residual chlorine is limited as a daily maximum because the
difference between the chronic effect level and the acute effect level is small, making
differentiations between weekly and daily averages statistically insignificant. The
previous permit was issued in error with a monthly limit. Additionally, it is improbable
that the 19µg/1 daily limit will result in added expenditure, since the standard error of
measurement for total residual chlorine is well in excess of the 9.5µg/1 differential.
3. Total phosphorous has been modified to reflect that compliance is based on a quarterly
average of weekly samples.
4. The instream sample locations have been corrected as requested.
5. The metals , as with other toxicants, are normally limited as daily maximums. However,
as discussed in the meeting and concurred to by. Burlington, the permit has been modified
to limit the metals on a weekly basis and a daily maximum. Under this option,
Burlington may collect multiple samples for the week and if the analysis of the first
sample is compliant with the weekly average, the remaining samples need not be
analyzed. If the sample is in excess of the weekly average, but compliant with the daily
maximum limitation, additional analyses should be run and averaged over the week to
determine compliance with the weekly average.
6. The limits for all parameters are based on protection of the water quality of the receiving
stream for the existing uses. The water quality standard for mercury and cyanide requires
that the effluent be limited at very low levels. When those limits are less than the current
detection levels, the permittee is considered to be in compliance if the measurement of

: r
r the parameter is below the detection level. A footnote has been added to the effluent
limitations that states that the quantity for purposes of compliance evaluation is
ti considered to be equivalent to zero if the parameter is detected below current detection
limits.
7. Monitoring and limits for toluene, tetrachloroethlyene and long-term BOD has been
removed from the permit.
8. Mass limits are not given for municipal discharges which have been given limits to
protect water quality standards, as opposed to technology -based limits. Mass limits are
also not given in situations were effluents dominate the flow in the receiving water under
low flow conditions as is the case for the Burlington discharge.
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 Administrative Hearings, Post Office Drawer 27447, Raleigh, North
Carolina 27611 -7447. Unless such demand is made, this decision shall be final and -binding.
Please take notice this permit is not transferable. PartII, EA. addresses the requirements
to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Environmental Management or permits required by the Division of
Land Resources, Coastal Area Management Act or any other Federal or Local governmental
permit that may be required.

' Part III Permit No. NCO023876
F. CHRONIC TOXICITY PAS S/FAII. PERMIT I = (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity 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 86% (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 the effective date
of this permit during the months of January, April, July and October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent 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
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and 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 alternate monitoring requirements or limits.
NOTE: Failure to 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.
G. Nutrient Condition for Permits with Phosphorus Limits
This permit may be modified, or revoked and reissued to change the effluent limitation on nutrients
for this discharge depending upon the following:
1. The findings of a study by the Division of Environmental Management determine nutrient
control is necessary.
2. Local actions do -not successfully reduce the nutrient loading on the receiving waters.

A I. The onset of problem conditions in the receiving waters.
H. Pollutant Analysis Condition
The permittee shall conduct a test for pollutants annually at the effluent from the treatment plant.
The discharge shall be evaluated as follows:,1) A pollutant analysis of the effluent must be
completed annually using EPA approved methods for the following analytic fractions: (a)
purgeables (i.e., volatile organic compounds); (b) acid extractables; (c) base/neutral extractables;
(d) organochlorine pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The
Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and accompanying
memo, to be provided to all discharges affected by this monitoring requirement, describes the
sampling and analysis requirements and lists chemicals to be included in the pollutant analysis.
This monitoring requirement is to be referred to as the "Annual Pollutant Analysis Monitoring
Requirement" (APAM).
(2) Other significant levels of organic. chemicals must be identified and approximately quantified.
For the purpose of implementing this requirement, the largest 10 GUMS peaks in the purgeable
base/neutral extractable, and acid extractable fractions (or fewer than 10, if less than 10
unidentified peaks occur) for chemicals other than those specified on the APA Requirement
Reporting Form A should be identified and approximately quantified as stated in the APAM
Reporting Form A instructions. This part (item 2) of the APAM requirement is to be referred to as
the "10 significant peaks rule").

referenced draft NPDES discharge permits as attachments A and B to this
letter. Please incorporate these comments into the official records of these
permits. We hope that you will give favorable consideration to our concerns
and objections.

Comments on Draft NPDES Permit No. NCO023876
South Burlington WWTP, Alamance-County
1. The Notification of Intent to Issue a State NPDES Permit, the draft
permit cover sheet, and the Supplement to Permit cover sheet all refer to
the South Burlington WWTP on Boy Wood Road as being in Burlington. In
(y' fact, this treatment facility is located in Alamance County outside'the
limits of incorporation of .surrounding cities or towns.
2. The proposed effluent limit for residual chlorine in summer and winter is
a daily maximum of 19 pg/l. Our previous permit included a monthly
average limit of 19 pg/1 residual chlorine and a weekly average limit of
28.5 pg/l./- We feel that the daily maximum limit of 19 pg/l is too
strict. Given the variable characteristics of the wastewater, the
\ reliance on multiple feedback signals to control chlorine and sulfur
dioxide dosages, and the instantaneous flow variability due to filter
backwashes it is conceivable that daily results could exceed 19 .Pg/l. To
overcome the lag in feed equipment response time and the percent error,
inherent in the equipment, a daily maximum limit would require a gross
overfeeding of sulfur dioxide. This will increase operation costs
because sulfur dioxide is expensive, and may adversely affect the
effluent toxicity. We request revision back -to the conditions of the
previous permit.
3. The -proposed effluent limit for total phosphorus in summer is a monthly
average of 2.0 mg/l. Our previous agreement with the permitting
authority, as reflected in our previous discharge permit was a quarterly
�average limit /1 with weekly sampling. Both the City o rham
an range Water and Sewer Authority have had permits issued within the
�QQP D last 12 months that contain a quarterly total phosphorus limit. In the
interest of consistency with past permit conditions and the constraints
�5� S placed on neighboring municipalities, we request that the phosphorus
limit be maintained at 2.0 mg/l as a quarterly average with weekly
(� sampling.
4. Sample location "Upstream Site 2" should be eliminated. It is a'few
hundred yards downstream of the East Burlington WWTP downstream sampling
site on the bridge at SR 2158. Both plants collect instream samples on
the same day, therefore "Upstream Site 2" is redundant. Also, there is
o access point at "Upstream Site 2" to collect a representative sample.
It was dropped from the previous permit based on an August 8, 1990 letter
from Steve Tedder.
5. The "Downstream Site 1" location should remain at the SR 2116 bridge on
Alamance Creek. The proposed Haw River location does not allow access
for a representative sample. It was dropped from the previous permit.
6. "Downstream Site 211 requires the use of a boat to gain access to a
representative sampling point. The permit should include a clause
exerapting sampling if the river flow is too high (dangerous) as was
agreed upon in the above referenced letter of August 8, 1990. The letter

L
ATTACHMENT'A (Continued)
Comments on Draft NPDES Permit No. NCO023876
South Burlington WWTP, Alamance County
states that flow at USGS gauge 02096500 at Haw River must be less than or
equal to 350 cfs. This was not an issue under the previous,permit, but
should be included for personal safety.
7. All summer and winter effluent metals limits are proposed as daily
maximum limits. This is inconsistent with the monthly average limits in
the previous permit. Given the potential for sample contamination,
analytical errors and interferences, and the percent errors inherent in
the analyses as you approach the method detection limits, several of
these limits appear too strict, and to make these a daily maximum limit
is potentially more damaging. Based on 1992 data, the following
parameters would have been violated:
a. Lead, one value exceeded 29 )Dg/l._
b. Mercury, our detection limit is- 0.2 pg/l. We reported several 0.2
pg/l values, possibly as a result of proximity to the detection
limit of the method.
c. Cyanide, more than 7 samples exceeded 5.0 Ng/l. The source of the
cyanide has not been determined, and may be the result of breakdown
of organic matrix interferences present in the influent.
d. Cadmium, 2.0 Ng/l was not exceeded in 1992, but several 2.0 pg/1
values were reported.
The City requests that the effluent limits for lead, chromium, cadmium,
nickel, mercury, fluoride, and cyanide be changed to monthly average
limits. We also request that limits for mercury and cyanide be revised
to a higher limit to reflect the actual plant treatment and lab analysis
capabilities.
8. The proposed effluent limit for toluene as a daily maximum with weekly
sampling does not seem reasonable. Toluene was not detected in the 1990
or 1991 annual pollutant analysis, and in 1992 only 2 µg/i was detected.
The analysis, according to',Burlington Research costs $70.00 per sample..
Weekly sampling would costi$3640.00 per year, a financial burden. The
City requests that toluene be dropped from the list of parameters on the
NPDES permit, and remain as part of the annual pollutant analysis.
9. Monitoring for tetrachloroethylene will cost $110.00 per sample according
to Burlington Research. It was not detectedin the 1990 or 1991 annual
pollutant analysis. In 1992,'12jug/1 was detected. The City does not
agree that tetrachloroethylene should be monitored as frequently as
monthly. The City requests that the frequency be revised to remain as
part of the annual analysis.
10. The long-term BOD requirement found in Part III.of this draft permit
should be removed. There is no approved method at this time and the
value -of data generated from such a test has not been demonstrated. The
City requests that this requirement be removed, recognizing that a clause

e
ATTACHMENT A (Continued)
Comments on Draft NPDES Permit.No. NC0023876

in the permit allows it to be reopened at a later time to insert
additional requirements.
11. Once again the City requests consideration for applying mass/day limits
rather than concentration limits. The South Burlington WWTP receives a
large industrial contribution and current discharge flows are well below
the permitted 12 MGD. Mass/day limits would be appropriate in this
IVV situation.

ATTACHMENT B
Comments on Draft NPDES Permit No. NC0023868
East Burlington WWTP, Alamance County
1. The Notification of Intent to Issue a State NPDES Permit, the draft
/ permit cover Sheet, and the Supplement to Permit Cover Sheet all refer to
l/ the East Burlington WWTP on Quarry Road as being in Graham. In fact,
this treatment facility is located in Alamance County outside the limits
of incorporation of surrounding cities or towns.
/ 2. The description of facilities on the Supplement to Cover Sheet omits the
flow equalization basin following the grit chamber and ahead of the
primary clarifiers. The flow equalization basin needs to be inserted.
3. The proposed summer and' winter effluent limit for total phosphorus is a
monthly average of 2.0 mg/1. Our previous agreement with the permitting
authority, as reflected in our previous discharge permit was a quarterly
L average limit of 2.0 mg/1 with weekly sampling. Both the City of Durham
and Orange Water and Sewer Authority have had permits issued within the
last 12 months that contain a quarterly total phosphorus limit.
Greensboro's phosphorus limit is also based on a quarterly average. In
the interest of consistency with past permit conditions and the
constraints placed on neighboring municipalities, we request that the
phosphorus limit be maintained at 2.0 mg/l as a quarterly average with
weekly sampling.
4. The description of the upstream sampling point states "50 feet from
discharge." There is -no sampling access available to guarantee a
representative sample. We have been sampling off of'the Hopedale Road
(SR 1712) bridge. Please review this sample location.
5. All summer and winter effluent metals limits are proposed as daily
maximum limits. This is inconsistent with the monthly;average limits in
the previous permit. Given the potential for sample contamination,
analytical errors and interferences, and the percent errors inherent in
the analyses as you approach the method detection limits, the proposed
limit for mercury is too low for our analytical method. We routinely
report <0.2jug/l, however because we are at the method detection limit we
have also reported several 0.2,ug/l values in 1992. Changing several of
the metals from monthly to weekly sampling frequency represents a steep
increase in our analytical workload.
The City requests that the effluent limits for lead, chromium, cadmium,
nickel, mercury, and fluoride be changed to monthly average limits. The
City further requests that the limit for mercury be revised to a higher
limit to reflect the actual plant treatment and lab analyses
capabilities.
6. Bis (2-ethylhexyl) phthalate was reported in ,the 1990 and 1991 annual
pollutant analyses at concentrations of 27.8 pg/1 and 99Pg/l. It was
not detected in the 1992 APA. Burlington Research has given us a price
of $150.00 to report all peaks that come out of the chromatograph during

the expected detention time window of bis (2-ethylhexyl) phthalate. This
would be an unconfirmed valve. To get a confirmation with standards and
a library match will cost $300.00. This translates to $15,600.00 per
year for weekly sampling. This is a compound found in plastics and
polymers and is frequently found as a sample contaminent from tubing and
containers. Because it has not been detected in concentrations
approaching the proposed limit, the City feels that a daily maximum limit
with weekly sampling is unreasonable. We request that this compound be
dropped from the NPDES-permit, and remain as part of the annual pollutant
analysis.
7. The City requests that summer and winter monitoring for copper be revised
to a monthly sampling frequency as it was in the previous permit.
8. Once again the City requests consideration for applying mass/day limits
rather than concentration limits. The East Burlington WWTP receives a.
large industrial contribution and current discharge flows are well below
the permitted 12 MGD. Mass/day limits would be appropriate in this
situation.

Subject: Instream Monitoring Requirements forlthe Burlington Southside WWTP
(NPDES No. NC0023876, Alamance Creek)
Dear Mr. Shoaf-
The Division of Environmental Management (DEW has reviewed your comments regarding the instream
monitoring requirements contained in the subject permit. DEM staff also traveled to the Haw River on July, 31, 1990,
to investigate the proposed monitoring sites, and concur with the difficulties you mentioned in your July 23 letter..
Based on the available information, the NPDES permit will be amended to include the following instream monitoring
requirements:
1. Alamance Creek, upstream of the discharge, at the NC Highway 87 bridge.
2. Alamance Creek near it's mouth at the SR 2116 bridge.
These sites should be sampled. all year for temperature, DO, fecal coliform, conductivity, and color, and should
include TP and PO4 in July through September. Frequency of instream monitoring will be three times per week
during June, July, August, and September, and once per week during the remaining months of the year. In addition,
weekly monitoring will be required at the following sites during the months of July, August, and September:
1. Three locations in Saxapahaw Lake (upper, middle, and lower, see attached map), depth
integrated at one meter intervals. Parameters include temperature, DO, conductivity,. pH,
TP, and PO4. Chlorophyll a should be measured once a month at these sites.
2. Downstream of Saxapahaw Dam at the SR 2171 bridge. Sampling should be done in
both the east and west channels of the river as long as there is flow in both channels.
Parameters include temperature, DO, conductivity, and pH.
3. At the SR 1005 bridge. Parameters include temperature, DO, conductivity; and pH.
These summer monitoring requirements will not be effective until.July 1, 1991, to give the City ample time
to make the necessary arrangements. The sites on Alamance Creek, however, -are effective immediately upon receipt of
this letter. As you have noticed, the upstream site on the Haw River near Swepsonville and the site downstream of the
confluence -of Alamance Creek and the Haw River have both been dropped due to the lack of adequate sampling
accessibility. The frequency of monitoring at the lower three sites has been changed.

The monitoring sites in and below Saxapahaw Lake are required only in the summer months when flows are
low and water quality problems would be most expected. The data generated will serve two purposes. First, it will
provide an indication of the water quality of the lake, the effect of the dam on water quality, and the magnitude of tha
subsequent DO sag below Saxapahaw. Although Dixie Yarns do-,s discharge below die dam, it is a very small volume
of domestic wastewater which will have very little to no effect on instream kinetics when compared to the large
discharges upstream, such as the two Burlington WWTPs.
The data gathered during the summers at the lower three sites will also serve to determine the impact, if any,
of the proposed Southside WWTP expansion on the downstream water quality. Gathered over time, these will reflect
any changes caused by an increase of wasteflow. Since no data in this area currently exist, and since the expansion has
already been approved by the Director, these requirements are justified to provide a retrospective evaluation of water
quality in the area.
Monitoring in the lake will require the use of a boat; the City will have to work with the Boy Scout Camp to
gain regular access to an acceptable boat ramp. Because the data are most useful at low flows, and because boating
may not be possible at high flows, monitoring at the lake sites will only be required when the streamflow at the
USGS gage 02096500 at Haw River, North Carolina, is less than or equal to 350 cfs. This gage is a telemetric
station, so the City can easily follow the daily flows by telephoning the gage itself. If you need assistance in
establishing a flow tracking system, you should contact either DEM or USGS. It is expected that flow in the Haw
River will usually meet the criteria, except after heavy rain events.
In closing, I would also like to remind you that long-term BOD will be required at some or all of the instream
monitoring sites when a standard procedure for it's measurement is formally adopted. If you have any questions or
comments regarding the permit modifications, please contact Trevor Clements or Mike Scoville of my staff at (919)
733-5083.

INSTRUCTIONS
The purpose of this document and the NC DEHNR memo of October 30, 1990 (Tedder)/mailing of December 1990 is to standard-
ize the sampling, analysis and reporting procedures to be used for the Annual Pollutant Analysis Monitoring (APAM) Require-
ment as described in the permit.
SammmpI i ng
1 - Take a 24-hour composite sample from the final effluent during mid -week (Wednesday through Friday). Collect a grab
sample for the volatile organic fraction when collection of the 24-hour composite sample is completed. Follow any other
sampling instructions provided by the laboratory performing the analysis.
2 - Indicate in the space provided on Page 1 of 13 this page whether a corresponding sample for toxicity testing was taken.
3 - Make note of any unusual wastewater treatment operating conditions -occurring on the day of sampling in the space pro-
vided on Page 1 of 13.
Analysis
4 - Analyze the effluent for pollutants listed on the APAM form, including those to be identified and approximately quan-
tified under the 10 significant peaks rule, using appropriate EPA -approved methods for each of the analytic fractions.
Other analytical methods can be substituted only with prior, written approval of the Director of the Division of Environmen-
tal Management (DEM(. Read and distribute to the laboratory performing the analysis the accompanying memo (Tedder, October
1990) clarifying analytical requirements.
5 - Identify chemicals to be analyzed for according to the 10 significant peaks rule (as described in item 2 of the Annual
Pollutant Analysis Monitoring Requirement in the permit) using a GC/MS library search. Tentative identification is all that
is required; confirmation by standard injection is not necessary. Estimate the concentration of each based on an internal
standard having the closest retention time.
Reporting
6 - Guantitation Limit Targets that should be met are listed on this Revised APAM Reporting Form A. Report the use of any
higher quantition limit and an explanation as to why the listed quantitation limit target could not be met. Examples of
acceptable reasons for not meeting a quantitation limit target could be high background concentrations in a sample, or the
necessity for sample fraction dilution to bring a chemical to within a quantifiable concentration. List any quantitation
Limit different (whether higher or lower) from the target in the column provided for the purpose.
7 - If a chemical is found to be below the quantitation limit, report the concentration detected as less than (or '<') the
quantitation limit in the appropriate space. Provide a concentration estimate for chemicals detected in concentrations
greater than the detection limit and less than the quantitation limit. Enter the detection limit in parentheses beside the
estimate. Chemicals detected in concentrations above the quantitation limits must be quantified. quantitation limit and
detection limit are defined in the NC DEHNR memo (Tedder, October 1990). Enter the total number of peaks detected in
each analytic fraction in the appropriate space on this Revised APAM Form A. Report all concentrations in units of micro-
grams per liter (ug/L) and metals as total recoverable metal. If no,peaks to be identified under the 10 significant peaks
rule are observed, enter "none" in the space provided for 'other" compounds in each appropriate analytic fraction section.
Provide the concentration estimate and retention time for "unknowns" as well as for "significant peaks" for which a struc-
tural assignment can be made.
8 - If "significant peaks" are found, provide probable molecular weight, library match probability, retention time, ident-
ification basis, and MS scan number each. In addition, list internal standards and their retention times.
9 - In the section labeled "Organic Analytical Information", (Page 11 of 13) include for each organic fraction the method,
extraction technique, GC operating conditions, and surrogate recovery. Report the size of the GC/MS library being utilized
in the appropriate space.
10 - Use copies of this Annual Pollutant Analysis Monitoring Revised Form A to report the.results of the analysis. Both
the analytical laboratory representative and the facility operator in responsible charge should sign completed forms.
(last page).
11 - Mail two completed copies of the form (and the laboratory report, if submitted to the facility on a different form)
to: ATTN: Central Files, Division of Environmental Management, NC DEHNR, P.O. Box 27687, Raleigh, NC 27611. Mail the APAM
form separately from Discharge Monitoring Reports.

Based on updated pretreatment data, silver should be monitored and lead should be limited.
Based on PPA, chloride and tetrachloroethylene should be monitored and fluoride and toluene
should be limited. Since these decisions are only based on one sampling event, the Winston-Salem
Regional Office staff should comment on the appropriateness of allowing the facility to monitor
only for fluoride and toluene during the first 12 months of the permit. This would provide a better
base of information to make a decision on limiting these toxicants.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity 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 fluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
qua_rjcjry monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed qfter thirty days from the effective date of this permit during the months of
J 0 .fir eICf . Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent 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
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and 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 alternate monitoring requirements or limits.
NOTE: Failure to 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.
