1. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent
versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 90% (defined as treatment two in the procedure document). The pen -nit holder shall perform
quarterjy monitoring using this procedure to establish compliance with the permit condition. The tests will be
performed during the months of March, June, September, and December. Effluent sampling for this
testing shall be performed at the NPDES permitted fmal 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, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 27607
Test data shall be complete and accurate and include all supporting chenvcal/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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Branch at the address cited above.
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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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
Water Quality 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, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day
of the month following the month of the initial monitoring.

Hello Mr. Pellei!
Tom Spain, with the City of Henderson called to discuss their Draft permit. He found
several glitches he would like to discuss with the permit writer A few he mentioned were
fecal coliform, chromium (shouldn't be required), winter/summer (months noted are
incorrect), and instream monitoring. Can you give him a call this afternoon?
Thanks!

Wasteload Allocation (WLA) Summarx
The WLA for the City of Henderson`s permit renewal for it's Nutbush Creek WWTP is for it's existing
4.14 MGD WWTP (6.0 MGD after expansion). All other parameters in the permit remain as in the previous
version. A brief WLA history is as follows:
1974: first WLA in files. Limits were 30 mg/l BODp, 15 mg/l BODS, 15 mg/1 SS, 3.5 mg/l TKN, and 200 mpn/100 ml fecal coliform. A
note is on this memorandum stating that effluent limitations are in error and corrected values should be determined.
1975: this looks like the updated limits from the 1974 request. ' BODS 12 mg/l, TKN 3 mg/I, 30 mg/I TSS, 200 / 106 ml fecal cotiform,
6-8.5SUpH, and 5mg/l DO.
1976: new limits for 1.84 - 3.7 mgd were established. I assume these represented summer / winter limits; UOD 46 / 53, BOD5 18 /
17, NH; N 7 / 9, TSS 30, fecal'coliform 200 / 100 ml, pH 6 - 8.5, DO 5 / 6. A note is also in the file indicating that an intensive
survey was performed in 1975 - 1976 including dye info., depth integrated DO's, and some nutrient data.
19B3: facility was remodeled for an expansion to 4.14 mgd. Limits were summer / winter: 5 / 8 mg/l BODS, 3 / 4 NH,-N, 5 mg/l DO,
1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH. Request from facility for reallocation, new limits of: 5 / 5 mg/l BODS, 3 / 12
NH,-N, 6 mg/I DO, 1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH were recommended.
1986: renewal due to request from facility to relafc BODS and NH; N limits by increasing dissolved oxygen requirement: 5 / 10 mg/l
BOD5, 3 / 6 NH; N, 7 mg/l DO, 30 mg/l TSS, 1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH were recommended. A
memorandum from Trevor Clement on this reallocation indicates that the newly modeled BODS and NH,-N limits will not be
decreased much by the additional dissolved oxygen input; due "to the high carbonaceous deoxygenatian rated used in the
model (k, - 1.5 / day). This rate was determined back in 1976 when the model was calibrated. At that time, Henderson
possessed only a secondary treatment facility and a pickle factory was discharging upstream of them. The pickle factory no
longer discharges..." However, there may be other influences on D.O. in Nutbush Creek, particularly from algal growth and
respiration, that are not accounted for in the existing model." Due to offset of these factors, the existing model was put into
use.
1988: a new wasteload analysis was completed which included another BODS and NH,-N trade out was completed: 6 / 12 mg/l
BOD5, 3 / 6 NH,-N, 7 mg/l DO. Along with these recommended limits, requirements for Cr, Pb, Cd, and Ni were included.
Also, summer / winter limits of 0.5 / 2 mg/l were recommended for Total Phosphorus. A chronic Toxicity Test and depth
integrated downstream monitoring with a nutrient series was recommended.
1988: Intensive Survey did a study on Kerr Lake and the various pertinent arms, (i.e. Nutbush Creek, Crooked Run, etc.). The
summary page of the study, (marked in WLA file) indicated many exceedences of the chlorophyll - a standard accompanied
by periods of zero - flow from the various arms, (tributaries) to the system. Water body coloring as well as secchi depth
measurements indicated impacts from the Henderson WWTP.
1989: a memorandum addressing the two studies, (1988 and another from the 1970's) concluded that "[t]he survey indicated that the
upper reach of the Nutbush Creek arm is hypereutrophic, with a trophic gradient to mesotrophic conditions at the downstream
extent of the sampling. The impact of the WWTP is of concern because of the bioavailability of the effluent nutrients, the lack
of dilution, and long retention time." This report addresses most of the issues dealt with in the 1989 Permitting of this facility
and is therefore necessary reading for any WLA re-evaluation,
note Empirical Phosphorus and Chlorophyll a Modeling section in Appendix A].

ammonia toxicity. nmontonng for Hg, Ln,•t;u, MbAb ana UN were requirea for the 4.14 mga now, wnue aaoitionai limits for UN,
Hg, MBAS, Cl, along with Cu, Zn, Ag, and As'monitoring were required for the 6.0 mgd flow. The Staff Report indicates that at
that time the City had requested a "modification to the Consent Judgment to include the expansion and upgrade of the WWTP.
The plant has had problems with meeting the BOD and NH,-N limits in the winter when cold temperatures and high flows
reduce treatment efficiency." The toxicity limit was also changed to a monitoring requirement in the JOC.
1994: much of the notes included are no longer in the file. However, basically they stated what the Draft Basin Plan notes about
instream nutrient levels. Extensive inslream data is available. The facility is still dealing with SOC's and NOV's for both metals
violations and I & I, (its is likely that the I & I is driving the problem). Both the Region and Pretreatment are in consistent
contact with the facility, therefore these problems should be handled on schedule.
Toxicity_Test
facility has very poor record and is taking the test every month - THE and TIE's are included in the SOC's therefore attention is
being given to this ongoing problem.
Instream 5amplina
Conditions at the headwaters of the Nutbush Creek Arm have in the past been nearly hypereutrophic. During low flow
conditions, Nutbush Creek is dominated by the effluent of the Henderson WWTP. A study conducted in 1988 by DWQ
indicated that the Henderson.WWTP was a major contributor of nutrients to Nutbush Creek.
Since the mid 1980's, DWQ has been working with the City of Henderson to resolve this problem including the implementation
of a phosphorus limitation in its NPDES permit. The Henderson WWTP has undergone a number of upgrades, including
phosphorus removal capabilities. Significant water quality improvements have been realized from the City's efforts. Data
collected by DWQ in 1994 ranked the lake as being mesotrophic. The lake's new ranking may indicate improvement due to
the WWTP's upgrades. DWQ will continue to monitor the Nutbush Arm of Kerr Lake.
Proposed Effluent Limitations:
Limits will essentially remain the same as in the previous permit with a few minor changes.
Reasonable Potential Caution$:
As a result of the reasonable potential calculations, monitoring/limits for Fluoride, and Cadmium were removed from the
permit, and monitoring/limit for Chromium was inserted.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodapnnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent
versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 90 % (defined as treatment two in the procedure document). The permit holder shall perform
guarrerly monitoring using this procedure to establish compliance wiih the permit condition. The tests will be
performed during the months of Mar., Jun., Sept., and Dec,. 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, DWQ Form AT-1 (original) is to be sent to the following address:
Auention. Environmental Sciences Branch
North Carolina Division of
Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the perminee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental, Sciences
Branch at the address cited above.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begirt 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 the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent
versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 90 % (defined as treatment two in the procedure document). The permit holder shall perform
auamrly monitoring using this procedure to establish compliance with the permit condition. The tests will be
performed during the months of Mar., Jun., Sept., and Dec.. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes -
A] I 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, DWQ Form AT 1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quali ty
4401 Reedy Creek Road
Raleigh, North Carolina 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 doselresponse 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 there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Branch at the address cited above.
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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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 rest data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality 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, minimum control organism reproduction, and appropriate environme tal controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no la than the last day

2. Special monitoring or limitations (including toxicity)
requests: YES, as per JOC (#88-04-AD II) Henderson was required
to conduct industrial waste survey, require industry to perform a
priority pollutant scan, submit a toxicity reductibA plan, (In
order to pass toxicity), long-term monitoring plan for pollutants
of concern, headworks analysis
Currently Henderson is NOT passing Toxicity (Between Dec. 1995 -
Nov. 1996 they passed one Tax. Test). They have requested an SOC
for Toxicity but have not signed it.
3. Important SOC, JOC or Compliance Schedule dates: (Please
indicate) - Henderson has completed its JOC- see below dates

Currently there is No SOC or JOC and Final Limits are
applicable. However, Henderson has requested an SOC in order to
address their toxicity problem. To date Henderson has not signed
this SOC.
4. Alternative Analysis Evaluation: Has the facility evaluated
all of the non -discharge options available. Please provide
regional perspective for each option evaluated.

5. Other Special Items:
PART IV -- EVALUATION AND RECOMMENDATIONS
The weirs of all of the clarifiers were observed to have
some build-up of algae, there was some grease, floating trash, -
and copious amounts of Lemna spp. observed in the C12 contact
chamber (note the Chlorine contact chamber is not being used).
Also, the trickling filters were observed to have some plastics
mixed throughout the media. The effluent was free from solids
but it had a notable burgundy hue. Also, both the post aeration
basin and the discharge/receiving stream had significant amounts
of foam. (The RRO is sending an NOV for the discharge of greater
than trace amounts of foam - permit limitation violation).
Henderson is addressing the color, foam, and MBAS with
Americal, Inc. Also, Henderson has requested an SOC in order
address toxicity. However, to date Henderson has not signed the
SOC.
FYI: As per Tom Spain, the ORC, Henderson currently has no plans
to expand the WWTP to 5 MGD. Accordingly, I recommend the
Central Office send the town of Henderson a letter asking for
clarification. That is, if additional treatment works are not
being proposed that Henderson requested the recision of the
expanded flow components of the permit. (This could prevent
unnecessary modeling and permit review)
The Raleigh Regional Office recommends renewal of NPDES
Permit No. NC 0020559.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Conditions at the headwaters of the Nutbush Creek Arm have in the past been nearly hypereutrophic.
During low flow conditions, Nutbush Creek is dominated by the effluent of the Henderson WWTP.
A study conducted in 1988 by DWQ indicated that the Henderson WWTP was a major contributor of
nutrients to Nutbush Creek.
Since the mid 1980's, DWQ has been working with the City of Henderson to resolve this problem
including the implementation of a phosphorus limitation in its NPDES permit. The Henderson
WWTP has undergone a number of upgrades, including phosphorus removal capabilities. Significant
water quality improvements have been realized from the City's efforts.
Data collected by DWQ in 1994 ranked the lake as being mesotrophic. The lake's new ranking may
indicate improvement due to the WWTP's upgrades. DWQ will continue to monitor the Nutbush
Arm of Kerr Lake.

Facility Name
Henderson - Nutbush WWTP Permit # NCO020559 Pipe # 001
CHRONIC TOXICITY PASSIFAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
l.) 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 90 % (defined as treatment two in the North Carolina procedure document). The permit
holder shall perform guarterIX 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 Mar., ,Tun., Sept., and Dec. 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.

1974: first WLA in files. Limits were 30 mg/I BODµ, 15 mg/I SODS, 15 mg/I SS, 3.5 mg/I TKN, and 200 mpn/100 ml fecal coliform. A
note is on this memorandum stating that effluent limitations are in error and corrected values should be determined.
1975: this looks like the updated limits from the 1974 request. BODS 12 mg/l, TKN 3 mg/I, 30 mg/I TSS, 200 / 100 ml fecal coliform,
6 - 8.5 SU pH, and 5 mg1l DO.
1976: new limits for 1.84 - 3.7 mgd were established. I assume these represented summer / winter limits; UOD 46 / 53, BODS 181
17, NH,-N 7 / 9, TSS 30, fecal coliform 200 / 100 ml, pH 6 - 8.5, DO 5 / 6. A note is also in the file indicating that an intensive
survey was performed in 1975 - 1976 including dye info., depth integrated DO's, and some nutrient data.
1983: facility was remodeled for an expansion to 4.14 mgd. Limits were summer / winter: 5 / 8 mg/I BOD5, 3 / 4 NH,-N, 5 mg/I DO,
1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH. Request from facility for reallocation, new limits of: 5 / 5 mg/I BOD5, 3 112
NH,-N, 6 mg/I DO, 1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH were recommended.
1986: renewal due to request from facility to relax BOD5 and NH; N limits by increasing dissolved oxygen requirement: 5 / 10 mgll
BODS, 3 / 6 NH,-N, 7 mg/I DO, 30 mg/I TSS, 1,000 / 100 ml Fecal Coliform, and 6 - 9 SU pH were recommended. A
memorandum from Trevor Clement on this reallocation indicates that the newly modeled SODS and NH,-N limits will not be
decreased much by the additional dissolved oxygen input; due "to the high carbonaceous deoxygenation rated used in the
model (k, - 1.5 / day). This rate was determined back in 1976 when the model was calibrated. At that time, Henderson
possessed only a secondary treatment facility and a pickle factory was discharging upstream of them. The pickle factory no
longer discharges..." However, there may be other influences on D.O. in Nutbush Creek, particularly from algal growth and
respiration, that are not accounted for in the existing model." Due to offset of these factors, the existing model was put into
use.
1988, anew wasteload analysis was completed which included another BODS and NH; N trade out was completed; 6 / 12 mg/I
BODS, 3 / 6 NH,-N, 7 mg/I DO. Along with these recommended limits, requirements for Cr, Pb, Cd, and Ni were included.
Also, summer / winter limits of 0.5 / 2 mg/I were recommended for Total Phosphorus. A chronic Toxicity Test and depth
integrated downstream monitoring with a nutrient series was recommended.
1988: Intensive Survey did a study on Kerr Lake and the various pertinent arms, (i.e. Nutbush Creek, Crooked Run, etc.). The
summary page of the study, (marked in WLA file) indicated many exceedences of the chlorophyll - a standard accompanied
by periods of zero - flow from the various arms, (tributaries) to the system. Water body coloring as well as secchi depth
measurements indicated impacts from the Henderson WWTP.
1989: a memorandum addressing the two studies, (1988 and another from the 1970's) concluded that "[tlhe survey indicated that the
upper reach of the Nutbush Creek arm is hypereutrophic, with a trophic gradient to mesotrophic conditions at the downstream
extent of the sampling. The impact of the WWTP is of concern because of the bioavailability of the effluent nutrients, the lack
of dilution, and long retention time." This report addresses most of the issues dealt with in the 1989 Permitting of this facility
and is therefore necessary reading for any WLA re-evaluation,
[ note Empirical Phosphorus and Chlorophyll a Modeling section in Appendix A].
1991: WLA requested for flows of 4.14 mgd and 6.0 mgd. The 6.0 mgd discharge received ammonia limits of 1 / 1.9 based on
ammonia toxicity. Monitoring for Ag, Zn, Cu, MBAS and CN were required for the 4.14 mgd flow, while additional limits for CN,
Hg, MBAS, Cl- along with Cu, Zn, Ag, and As monitoring were required for the 6.0 mgd flow. The Staff Report indicates that at
that time the City had requested a "modification to the Consent Judgment to include the expansion and upgrade of the WWTP.
The plant has had problems with meeting the BOD and NH,-N limits in the winter when cold temperatures and high flows
reduce treatment efficiency." The toxicity limit was also changed to a monitoring requirement in the JOC.
1994: much of the notes I included are no longer in the file; I don't know where they are, but basically they stated what the Draft
Basin Plan notes about instream nutrient levels. Extensive instream data is available on this computer within the Henderson
file. The facility is still dealing with SOC's and NOV's for both metals violations and I & I, (its is likely that the I & I is driving the
problem). Both the Region and Pretreatment are in consistent contact with the facility, therefore these problems should be
handled on schedule.
Toxicity Test
facility has very poor record and is taking the test every month - THE amd TIE's are included in the SOC's therefore attention is being
given to this ongoing problem.

Instream Samgii W
Conditions at the headwaters of the Nutbush Creek Arm have in the past been nearly hypereutrophic. During low flow
conditions, Nutbush Creek is dominated by the effluent of the Henderson WWTP. A study conducted in 1988 by DWQ
indicated that the Henderson WWTP was a major contributor of nutrients to Nutbush Creek.
Since the mid 1980's, DWQ has been working with the City of Henderson to resolve this problem including the implementation
of a phosphorus limitation in its NPDES permit. The Henderson WWTP has undergone a number of upgrades, including
phosphorus removal capabilities. Significant water quality improvements have been realized from the City's efforts as
indicated in Figures 6.3 and 6.4.
Data collected by DWQ in 1994 ranked the lake as being mesotrophic. The lake's new ranking may indicate improvement due
to the WWTP's upgrades. DWO will continue to monitor the Nutbush Arm of Kerr Lake.
Draft Plan 6.4.2
Facility now keeps instream data on computer and will be sending me a disk of it. Because of this review in Basin Plan, I will
not wait to receive this disk before processing this WLA.
