Subject: NPDES Draft Permit
Permit no. NC0020559
City of Henderson Water Reclamation Facility
Vance County
Dear Mr. Spain:
Please find enclosed the DRAFT permit for the subject wastewater treatment plant for your
review and comment. The draft permit includes the following items:
• The name of the facility was changed to City of Henderson Water Reclamation Facility as
requested.
• The monitoring schedule for whole effluent toxicity testing was changed to January, April,
July and October as requested.
• Limits for Lead and MBAS were eliminated and monitoring was modified to twice per
month. A reasonable potential analysis shows no reasonable potential to exceed water
quality standards for these parameters.
• A special condition was added to the permit specifying annual pollutant scan monitoring of
the effluent. The Division is implementing the annual monitoring requirement for all POTW
with effluent flows greater than 1.0 MGD or with a pre-treatment program. The total set of
samples collected during the permit cycle shall represent seasonal variations. The
requirement to monitor for these pollutants is part of the information required by the
federal regulations for municipal dischargers.
Mercury continues to be a water quality concern throughout North Carolina. Holders of
NPDES permits have worked with the state to reduce potential risks from this pollutant,
including tasks associated with collecting and reporting more accurate data. The most
commonly used laboratory analysis (EPA Method 245.1) has a detection limit of 0.2 ug/L while
the current water quality standard is an order of magnitude lower at 0.012 ug/L. A more
recently approved analytical test (EPA Method 1631) should produce a detection limit below the
level of the standard. This will allow the Division to assess potential water quality impacts
from discharges more accurately. Therefore, beginning on or before September 1, 2003, you
will be required to begin using EPA Method 1631 when analyzing for mercury.
The Division may re -open this permit to require weekly average limits for ammonia. After
calculating allowable concentrations, the Division will perform an analysis of past ammonia
data to determine if there is a reasonable potential for this discharge to exceed these potential
limits. If there is, this permit will be re -opened. If there is not, the permit will not be re-
opened, but will contain weekly average limits for ammonia upon renewal.
Please provide any comments you have regarding the draft permit to this office by
September 17, 2002. At this time, the Division is also publishing a notice in the newspapers
of general circulation in Vance County, inviting public comment on the draft permit. Following

Summary
The City of Henderson requested the renewal of the NPDES permit. The application was submitted
to the Division on October 30, 2001. The application received is an older form of the application. The
Division accepted this application because the City requested, both verbally and written, an
application form around August 2001 and was given this form to complete. The Division has accepted
this application but required additional information to fulfill the requirements of 40CFR122. Two
changes were requested at the time of permit renewal; to change the name of the facility to City of
Henderson Water Reclamation Facility and to change the months in which the toxicity test is done to
coincide with the pretreatment sampling. Both changes are included in the draft permit.
Facility Description The facility consists of a bar screen and grit chamber, parshall flume, influent
flow meter, primary clarifiers, trickling filters, secondary clarifiers, pure oxygen activated sludge
nitrification basin, final clarifiers, tertiary filters, post aeration, UV disinfection and sodium hypochlorite
backup, dissolved air flotation sludge thickening, pure oxygen
aerobic digester, sludge holding tank and sludge drying bed.
Basin Plan The 2001 Roanoke Basin Plan lists Nutbush Creek as impaired due to biological
degradation. Nutbush Creek received a fair bioclassiffication in 1999. Continued monitor of the
stream and the discharge from Henderson was recommended. Stormwater runoff, sedimentation
and collection system problems were also identified as contributing to the degradation of the stream.
Pre-treatment This NPDES permit requires Henderson to maintain a Long Term Monitoring Plan
(LTMP) and Pretreatment Program under federal regulations 40CFR 403 and NC State regulations
15A NCAC 2H.0900. The City has an approved pre-treatment program with 7 significant industrial
users.

Whole Effluent Toxicity (WET) - The permit requires a ceriodaphnia chronic pass/fail toxicity test at
90% effluent. During 1998 and 1999 the facility failed 13 out of 21 tests. During 2000 and 2001 they
failed 4 out of 18 tests. The last failure was in September 2001.
The City of Henderson performed a Toxicity Reduction Evaluation. The toxicity failures were related to
industrial activities. The City has been working with the industrial dischargers over the past few years to
identify and address the sources of toxicity. Improvements have been made and several industries have
changed their processes or raw materials to reduce toxic substances in their effluent. Some industries
are still showing sporadic toxicity in their effluents and studies are under way to address them. As a
result of the toxicity evaluation they implemented a physical change to the treatment system which
consisted of the installation of a granulated activated carbon effluent filter. The measures implemented
by the city have shown positive results.
DMR Effluent Data Review - DMR data was reviewed from January 1999 to December 2001. No
violations of permit limits were reported except as noted above for whole effluent toxicity.
Reasonable Potential Analysis — A reasonable potential analysis was performed for chromium,
copper, lead, silver, zinc, MBAS and mercury. The results are summarized in the following table:

standard for all samples. DO levels were above 5 mg/I on all sampling locations.
Waste Load Allocation (WLA)
The last waste load allocation was done in 1996.
SUMMARY OF PROPOSED CHANGES
• The limits for lead and MBAS were eliminated based on the results of the reasonable potential
analysis. Monitoring was reduced to 2/month.
■ The name of the facility was changed to City of Henderson Water Reclamation Facility.
• The schedule for toxicity monitoring was changed to January, April, July and October.

RETURN RECEIPT REQUESTED
Mr. Tom Spain
City of Henderson
PO Box 1434
Henderson, North Carolina 27536
SUBJECT: NOTICE OF VIOLATION
Whole Effluent Toxicity (WET) Testing
Copperand Zinc Action Level Policy
NPDES Permit No. NC0020559
City of Henderson WWTP
Vance County
Dear Mr. Spain:
This is to inform you that a review of your toxicity self -monitoring report form for the month of
September 2002 indicates a violation of the toxicity limitation specified in your NPDES Permit. You
should undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In 2ddition. this ccrrespondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by two or more toxicity limit violations that occur during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and is exceeding the action level for
these parameters. The policy states that whenever a facility experiences two or more toxicity limit
violations during a toxicity testing calendar quarter, the NPDES Permit will be modified to include
numeric limits for copper and/or zinc UNLESS the permittee provides one or more of the following:
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard .. _ .
2. - A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. '. 'ToxkiiyIdentification Evaluation (TIE) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

The Division has evalua your copper and/or zinc monitoring dat'�he Division has also 2
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure. Based on this data your prospective
copper permit limit is 16 µg/1, and prospective zinc permit limit is 129 µg/L.
The permittee, upon experiencing two or more toxicity limit violations during a toxicity
testing calendar quarter must either provide DWQ with:
a) Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation.
W
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Please note that if you choose item b) above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s). Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to'include copper and/or zinc numeric limitations, as appropriate.
Please note that your.actions to notifyDWQ of prospective limit acceptance or to notify DWQ
of plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.

0 0
If the effluent is toxic, then we expect work to commence immediately with toxic effluent
samples. Failure to initiate work with toxic effluent samples during the study period is unacceptable and
will be considered a failure to make acceptable demonstration as cited above. We recommend a
minimum of three separate sampling events during the nine month period to definitively rule out copper
and/or zinc as causative effluent toxicants.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
Additional information regarding the Division's copper and/or zinc action level policy can be
found at the following web site - http://www.esb.enr.state.nc.us. Click on the "Aquatic
Toxicology" Unit and go to the prompt "DOWNLOADS" located at the bottom of the page. This web
site also contains EPA's "Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment
Plants." Section 4 of this document contains pertinent information on Toxicity Identification
Evaluations.

• NORTH CAANA ACTION LEVEL WAT%QUALITY
STANDARDS BRIEF
In 1984, North Carolina adopted Action
Level water quality standards for copper,
zinc, iron, and silver. These standards were
developed to prevent the State from having
to adopt the EPA criteria for metals, which
at the time were overly restrictive.
Action Level water quality standards are
a special category of surface water quality
standards, which are flexible, instream
criteria established for certain substances
that meet the following conditions:
• The chemical must be non-
bioaccumulative (BCF<100);
• The chemical must have variable
toxicity due to its chemical form,
solubility, affinity for other ligands,
or other characteristics; and
• The aquatic species used for whole
effluent toxicity (WET) testing must
be among the most sensitive biota to
that particular chemical, based on
available toxicity data.
In the early 1980's EPA was_ just
discovering the mechanisms that made these
metals toxic. One of the things that was
clear was that, in most waters, only a portion
of the total metal concentration is
bioavailable. At the time, the best method
for determining the bioavailable portion of
the metal was WET testing. Thus the
standard was written to allow a facility to
calculate a morg site -specific metals limit
using a measure of bioavailability and was
implemented using WET testing.
Under the Clean Water Act, EPA must
approve all .. state standards _..- and
reclassifications. In 1985, 1986 and 1990
when EPA reviewed the action level water
quality standards they only conditionally
approved them. They had concerns related
to the fate and transport of the metals in
natural systems. In order to get the
conditional approval, which prevented EPA
from promulgating standards .for -North
Carolina, the Division committed. to
conducting fate and :transport studies on
selected metals,�including copper and zinc,
contingent on adequate funding. Several
study plans were developed and presented to
EPA for funding. No funding was made
available.
When these standards were adopted,
EPA requested information on how the
Action Level standards would be
implemented. The implementation
procedure presented to EPA involved
establishing WET testing limits and
monitoring for discharges with copper or
zinc in their effluent. No permit limits for
the metals were to be given if the facility
continued to pass their WET limits or if
upon failure of the WET testing an action
level parameter was not found to be a
causative factor.
EPA was uncomfortable with this
process and, when other states began asking
about using a similar approach, they became
even more uncomfortable.
While North Carolina was using its
action level standards. EPA was grappling
with metals criteria. The original national
criteria were so low that some pristine
streams had higher background
concentrations of copper and/or zinc and
would have been considered impaired. In
recent years, EPA has developed equations
and procedures for determining site -specific
metals criteria and for measuring more
precisely the bioavailable metals.
During the last Triennial Review, North
Carolina agreed to modify the action level
language to reference EPA's guidance on
developing site -specific metals criteria and
to provide a detailed Implementation
Procedure for action level standards. Had
North Carolina not taken these actions, EPA
was ready to promulgate straight standards
for metals for North Carolina based on
perceived successes in other states. This
action would have resulted in permit limits
for copper and zinc in most NPDES permits.
The Implementation Procedure that the
Division is beginning to implement was
reviewed. by EPA and reworked by the
Division several times during 1999 and 2000
before EPA finally approved it in October
2000.

PRESS RELEASE
e City of Henderson experienced numerous bypasses of untreated wastewater from its
Ilection System and Wastewater Pumping Stations between 5:00 AM and 1:36 PM on
mday, August 26, 2002. The bypasses were caused by the inflow and infiltration from
heavy rainfall into the stations.
Sandy Creek, Redud Creek and Nutbush Creek have elevated bacterial contamination as
a result of the bypass and the public should avoid contact with the waters until the
bacterial level returns to normal.
Those bypasses in the Tar Pamlico River Basin were:
Location Amount Bypassed
Booth Street/Winder Street 7,500 gallons
Pinkston Street (Green Acres Apt) 7,500 gallons
Shank Street/Lenoir Avenue 3,000 gallons

NMUSH CREEK WASTEWATER
TREATMM PLAN
I am requesting renewal of the City of Henderson's Nutbush Creek Wastewater
Treatment Plant Permit which is due to expire April 30, 2002.
A completed permit renewal application is enclosed.
I have attached a copy of our existing permit at 4.14 MGD and 6.0 MGD to begin upon
expansion. I definitely want to renew both the 4.14 MGD and 6.0 MGD permits.
I completed the permit renewal on the form specified by the State Permits and
Engineering Unit when I called them two months ago.
I had a conversation with Natalie Sierra of your office today and she said EPA had
developed a new form for permit renewals, but I could submit the old form and a
determination would be made on whether I had to use the new form.
I certainly hope this will be acceptable since I made both a written and verbal request to
the State for a permit renewal application and was referred to the State Web Site to
download it.

Please contact me at 252-431-6081 if you need additional information.
Thank you for your assistance in processing this permit renewal for the City of
Henderson.

The City of Henderson is mandated by the State in a Special Order of Consent (SOC) to
stop the bypasses of the Redbud Pump Station and provide adequate gravity sewer
conveyance to the Nutbush Creek Wastewater Treatment Plant.
The proposed project includes upgrade of the Redbud Pump Station capacity and
installing a larger gravity interceptor to the Wastewater Treatment Plant.
Plans and specification are complete, bids have been taken for the project and finding is
available.
The City has been delayed for six months by the State's review and approval of an
Environmental Assessment.
I am attaching a project schedule and a copy of the SOC but the City will be requesting
an extension of the dates in the SOC to allow time to complete construction.

(a) That the City holds North Carolina NPDES Permit No. NC0020559 for
operation of an existing wastewater treatment works and for making an outlet
therefrom for treated wastewater to Nutbush Creek, Class C waters of this State in
the Roanoke River Basin, but is unable to consistently comply with the final
effluent limitations for Chronic Toxicity set forth in the Permit. Compliance will
require the continued implementation of the Toxicity Reduction Evaluation. This
plan should consider but is not limited to items contained in 2(c)(1). In addition,
the City has reported overflows from the sewer collection system, especially
Redbud pump station, and elevated flows in the WWTP due to excessive inflow
and infiltration. As outlined 2 (c) (8-12) compliance will require further evaluation
of the redbud pumpstation improvements and potential construction activities based
upon that evaluation.
(b) That noncompliance with final effluent limitations and unauthorized discharges
of untreated sewage constitutes causing and contributing to pollution of the waters
of this State named above, and the City is within the jurisdiction of the Commission
as set forth in G.S. Chapter 143, Article 21.
(c) That the City desires to cause or allow the discharge of 400,000 gpd of
additional wastewater (system wide) to the treatment works, and that the discharge
of such additional wastewater will not result in any significant degradation of the
quality of any waters. See item 5.
(d) If Phase H is required, the City will secure fiIiiancing for planning and possible
construction /upgrade of a pump station which, if constructed and operated, will be
sufficient to adequately handle wastewater flows, and eliminate overflows from the
pump station.

DWQ, by check payable to the North Carolina Department of Environment and Natural
Resources, stipulated penalties according to the following schedule for unjustified failure to
meet the deadlines set out in paragraphs 2(c) and 2(e), or unjustified failure to attain
compliance with the effluent limitations/monitoring requirements contained in Attachment
A.
Failure to meet a schedule date listed in $100/day for the first 7 days; $500/day
either 2(c)(8), 2(c)(9), 2(c)(10), 2(c)(11), or thereafter.
2(c)(12).
Failure to achieve compliance with final
effluent limits by September 30, 1999.
Failure to eliminate overflows from the
Redbud pump station by March 1, 2002
Failure to monitor effluent toxicity
Failure to install replacement pump(s) as
specified in 2 0)
Failure to submit progress reports
$10,280 (single penalty).
$5,140 (single penalty).
$2000 per violation.
$1000 per violation. Does not apply if no
overflow occurs.
$50/day for the first 7 days; $250/day
thereafter.
4. The City and the Commission agree that the stipulated penalties are not due if the City
satisfies the DWQ that noncompliance was caused solely by:
a. An act of God;
b. An act of war•,

c. An intentional act or omission of a third party but this defense shall not be
available if the act or omission is that of an employee or agent of the defendant or if
the act or omission occurs in connection with a contractual relationship with the
pemiittee;
d. An extraordinary event beyond the permittee's control. Contractor delays or
failure to obtain funding will not be considered as events beyond the permittee's
control; or
e. Any combination of the above causes.
Failure within thirty (30) days of receipt of written demand to pay the penalties, or
challenge them by a contested case petition pursuant to G.S. 150B-23, will be grounds for
a collection action, which the Attorney General is hereby authorized to initiate. The only
issue in such an action will be whether the thirty (30) days has elapsed.
5. In accordance with the provisions of G.S. 143-215.67(b) the Commission allows the
City to accept the additional waste specified below to its waste disposal system. If the wet
weather I &I evaluation of Redbud collection system and pump station upgrades indicate a
continuing problem with overflows then the allocation of additional unpermitted flows
tributary to the Redbud pump station will be allowed upon acceptable demonstration to the
Director of the removal of an amount of inflow and infltration which is twice the amount of
new flow to be connected. The approval of additional flow will be in the form of a letter
from the Director to the City.
Total Domestic and Non -Domestic Flow 400,000 gpd
Total Flow allocated = 400,000 gpd, the nature of the additional flows is such that the
waste characteristics do not exceed those generally associated with domestic waste or are
pretreated to domestic strengths. Waste of greater than normal domestic strength may be
accepted if the parameter(s) that exceed normal domestic strength wastewater are not those
for which interim limitations have been developed and it can be demonstrated to the
satisfaction of the Director the additional waste will not adversely affect the treatment
efficiency of the treatment system for any modified parameter or result in the violation of
any other permit limitation. All new and proposed industrial waste tributary to the system
must be controlled using all needed mechanisms including but not limited to adoption and
implementation of industrial waste control and pretreatment ordinances. No wastewater
can be accepted which will add toxic pollutants in quantities not generally associated with
domestic wastewater characteristics, unless the acceptance of the additional wastewater can
be supported through appropriate analyses acceptable to the Director.
6. This Special Order by Consent and any terms, conditions and interim effluent
limitations contained herein, hereby supersede any and all previous Special Orders and
Enforcement Compliance Schedule Letters, terms, conditions, and limitations contained
therein issued in connection with NPDES Permit No. NC0020559.

7. Any violation of terms of this Special Order by Consent, including paragraphs 2(c) and
2(e) above and Attachment A shall terminate paragraph 5 of this Order and any authorized
additional waste not previously connected to the system shall not thereafter be connected
until the necessary sewerage system improvements have been completed and placed in
operation.
8. Noncompliance with the terms of this Special Order by Consent is subject to
enforcement action in addition to the above stipulated penalties, including injunctive relief
pursuant to G.S. 143-215.6.C.
9. The permittee, upon signature of the Special Order by Consent, will be expected to
comply with all schedule dates, terms, and conditions of this document.
10. This Special Order by Consent shall expire June 1, 2002.

Nutbush Creek Wastewater Treatment Plant
Sludge Management Program
The primary, trickling filter secondary and aeration tank activated sludges are processed
through a dissolved air floatation unit and thickened to a range of 4% to 6% total solids.
Approximately 13,260 gallons of sludge at 4% to 6% solids are produced daily.
The sludge is pumped to two pure oxygen aerobic digesters with an average detention
time of 2.3 days.
The sludge is heated in these digesters to a range of 110 degrees F to 130 degrees F by an
autothermal biological reaction.
The sludge then enters a primary anaerobic digester with recirculation and gas perth
mixing.
The sludge is digested at 95 degrees F to 99 degrees F for an average of 16.6 days in this
digester.
The sludge then enters a secondary anaerobic digester where supernatant is removed
when possible.
The sludge is further digested in this tank at 60 degrees to 80 degrees F for an average of
13.1 days.
The sludge is then pumped to a 1,000,000 gallon sludge holding tank with an average
detention time of 60 to 75 days.
The stabilized sludge is land applied at agronomic rates to permitted farm land by a
private contractor, Granville Farms, Inc.
The sludge is analyzed periodically for total solids, total volatile solids and pH.
In addition, all of the required sludge permit analysis are performed quarterly and TCLP
annually.
Alum sludge from phosphorus removal may be generated in the final clarifiers but at
present Ferrous Sulfide added to the collection system is removing phosphorus.
If alum is used, this sludge will be digested in a new 1,000,000 gallon aerobic digester for
approximately 60 to 80 days and then it will be pumped to the 1,000,000 gallon sludge
holding tank and blended with the other sludges for land application.
The plant still has 31 sand drying beds that can be used
to store sludge if needed.

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 permit holder shall perform
quarterly 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 final effluent discharge below all treatment processes.

SUBJECT: NOTICE OF VIOLATION
Whole Effluent Toxicity (WET) Testing
Copper and Zinc Action Level Policy
NPDES Permit No. NCO020559
City of Henderson WWTP
Vance County
Dear Mr. Spain:
This is to inform you that a review of your toxicity self -monitoring report form for the month of
September 2001 indicates a violation of the toxicity limitation specified in your NPDES Permit. You
should undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by two or more toxicity limit violations that occur during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and is exceeding the action level for
these parameters. The policy states that whenever a facility experiences two or more toxicity limit
violations during a toxicity testing calendar quarter, the NPDES Permit will be modified to include
numeric limits for copper and/or zinc UNLESS the permittee provides one or more of the following:
I. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation (TIE) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

Also note that IPT limit will remain in your NPDES pal gardless of whether metals 3
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
Additional information regarding the Division's copper and/or zinc action level policy can be
found at the following web site - http://www.esb.enr.state.nc.us. Click on the "Aquatic
Toxicology" Unit and go to the prompt "DOWNLOADS" located at the bottom of the page. This web
site also contains EPA's "Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment
Plants." Section 4 of this document contains pertinent information on Toxicity Identification
Evaluations.
If you have any questions concerning this correspondence, please contact me at [phone]
or Mr. Matt Matthews, Supervisor of the Aquatic Toxicology Unit at [phone].

11UNI" t—ARUMINA ALIMIr LEVEL WAFER QUALITY
0 STANDARDS BRIF49
In 1984, North Carolina adopted Action
Level water quality standards for copper,
zinc, iron, and silver. These standards were
developed to prevent the State from having
to adopt the EPA criteria for metals, which
at the time were overly restrictive.
Action Level water quality standards are
a special category of surface water quality
standards, which are flexible, instream
criteria established for certain substances
that meet the following conditions:
• The chemical must be non-
bioaccumulative (BCF<100);
• The chemical must have variable
toxicity due to its chemical form,
solubility, affinity for other ligands,
or other characteristics; and
• The aquatic species used for whole
effluent toxicity (WET) testing must
be among the most sensitive biota to
that particular chemical, based on
available toxicity data.
In the early 1980's EPA was just
discovering the mechanisms that made these
metals toxic. One of the things that was
clear was that, in most waters, only a portion
of the total metal concentration is
bioavailable. At the time, the best method
for determining the bioavailable portion of
the metal was WET testing. Thus the
standard was written to allow a facility to
calculate a more site -specific metals limit
using a measure of bioavailability and was
implemented using WET testing.
Under the Clean Water Act, EPA must
approve all state standards and
reclassifications. In 1985, 1986 and 1990
when EPA reviewed the action level water
quality standards they only conditionally
approved them. They had concerns related
to the fate and transport of the metals in
natural systems. In order to get the
conditional approval, which prevented EPA
from promulgating standards for North
Carolina, the Division committed to
conducting fate and transport studies on
selected metals, including copper and zinc,
contingent on adequate funding. Several
study plans were developed and presented to
EPA for funding. No funding was made
available.
When these standards were adopted,
EPA requested information on how the
Action Level standards would be
implemented. The implementation
procedure presented to EPA involved
establishing WET testing limits and
monitoring for discharges with copper or
zinc in their effluent. No permit limits for
the metals were to be given if the facility
continued to pass their WET limits or if
upon failure of the WET testing an action
level parameter was not found to be a
causative factor.
EPA was uncomfortable with this
process and, when other states began asking
about using a similar approach, they became
even more uncomfortable.
While North Carolina was using its
action level standards, EPA was grappling
with metals criteria. The original national
criteria were so low that some pristine
streams had higher background
concentrations of copper and/or zinc and
would have been considered impaired. In
recent years, EPA has developed equations
and procedures for determining site -specific
metals criteria and for measuring more
precisely the bioavailable metals.
During the last Triennial Review, North
Carolina agreed to modify the action level
language to reference EPA's guidance on
developing site -specific metals criteria and
to provide a detailed Implementation
Procedure for action level standards. Had
North Carolina not taken these actions, EPA
was ready to promulgate straight standards
for metals for North Carolina based on
perceived successes in other states. This
action would have resulted in permit limits
for copper and zinc in most NPDES permits.
The Implementation Procedure that the
Division is beginning to implement was
reviewed by EPA and reworked by the
Division several times during 1999 and 2000
before EPA finally approved it in October

Ammended DMR Reports
Dear Mr. Schuster,
NUTBUSH CREEK WASTEWATER
TREATMENT PLANT
The City of Henderson conducted an internal audit of the past 12 months of daily
monitoring reports (DMRs) and all laboratory bench note records to check for any
transcription or math errors.
We have had two new lab supervisors and two new lab technicians during this time
period and felt it was prudent to conduct this internal audit.
I am submitting revised DMRs for January through July of 2001 and have included
summaries of the changes as well as the complete amended DMRs.
None of the errors corrected on the DMRs had any impact on compliance, but we
have made the following procedure changes to ensure that we keep our lab bench
sheets and DMRs error free:
1. We reviewed all of the lab bench sheets and modified most of them to simplify the
data entry.
2. The Lab Supervisor reviewed and conducted training on the proper methods for
calculation of all the parameters with the lab staff.
The Lab Supervisor will be responsible for checking all lab bench notes for math or
transcription errors prior to completing a DMR and submitting it to the Plant Chief
Operator for review. The Chief Operator will check for errors and then forward the
DMR to the Plant Director for a final review and signature. The Plant Director will
forward the DMR to the Assistant City Manager for the permittee signature.

Dear Mr. Spain:
As part of the requirements of the Pretreatment Compliance Inspection conducted on June 12,
2001, the City of Henderson was required to submit SIU data summaries along with copies of all
Notices of Violations (NOVs) or Notice of Noncompliances (NNCs) issued. The information
was received by the Division on July 24, 2001.
After reviewing the data it appears that the City of Henderson is still not documenting violations
properly. Attached is a list of violations highlighted in the data summaries for which there seems
to have been no NOV or NNC issued.
Normally, this correspondence would be issued as a NOV, but there are mitigating
circumstances; specifically the abrupt departure of the City's Pretreatment Coordinator. The
efforts made by Ms. Leyen and yourself to maintain the program, while managing your already
demanding work loads, is another factor. The City has made commendable progress within the
Pretreatment Program, but enforcement action must be taken in a more timely manner. Provide
the following information by November 30, 2001.
1. Data summaries for all SIUs for the year 2001.
2. Copies of NOVs or NNCs issued for violations occurring to date. You do not have to
include copies of those NOVs already sent to the Division in the July 24 submission.
3. Any specific comments you have regarding any of the violations, in particular those listed
on the attachment.

Reviewing this data now and "catching up" on enforcement action will put the City in a good
position for the Pretreatment Annual Report (PAR). Future instances of failure to properly

Dear Mr. Schuster,
I was surprised by Ms. Brower's call to the Raleigh Regional Office.
Uj W `r-p
NLMSH CREEK WASTEWATER
TREATMENT PLANT
I asked my new lab supervisor, Qing Zhou, to contact Connie Brower to be sure we were
correctly reporting an effluent phosphorus test that we had run on a sample three times.
We have been reporting averages of all valid data in the past, but I wanted to be sure we
would report these three duplicates as an average of all the results or should we report
them as three separate results.
We have reported all data on our DMR's with the exception of nine influent metals (3
copper) (3 zinc) and ( 3 lead) for the month of June, 2001.
We have been running some of our metals in-house and some at Tritest because of
equipment problems.
My lab supervisor had left prior to June's DMR and during this transition these results
were inadvertenly left off the report.
We will promptly file an amended report for June with these parameters.
Since we found these metals left off the DMR for June, I had my lab supervisor and
chemist pull all the lab bench sheets for 12 months to recalculate all the data to be sure it
was correct.

0 r
They found some minor math and transcription errors that were not related to failing to
average or report valid data and do not impact compliance of our effluent limits.
We will promptly file amended reports correcting these errors.
To prevent the likely hood of a math or transcription error occurring in the future, I have
required the lab supervisor to check all bench notes for math and transcription errors prior
to submitting the DMRs for my review.
My lab supervisor, Qing Zhou or I will be glad to contact Ms. Brower to discuss the
instances when it is approporiate to invalidate data, but I hope in doing so that it doesn't
lead to this type of confusion again because we were and are reporting averages of
replicates and do not invalidate data unless it meets the criteria to be invalid.
We have always cooperated with the State to correct any laboratory problems noted and
will continue to do so.
Please contact me at 252-431-6081 if you have any questions.

Subject: Response to your letters
City of Henderson Sandy Creek Overflows
Vance County
Dear Ms. Veeder:
Your letters dated August 16, 2001 and September 1, 2001 to Coleen Sullins and Bill
Ross have been referred to this office for investigation and response. You letters indicate that
you are concerned about repeated overflows from the Sandy Creek Pump Station and the effect
on Sandy Creek. The Division shares your concern and is currently issuing Collection System
Permits to address maintenance and operation of collection systems.
Division of Water Quality Staff have reviewed the history of overflows from the Sandy
Creek Pump Station. In 2001, the City has reported 3 overflows totaling 34,250 gallons. All
three of these overflows were caused by heavy rain events resulting in more flow coming to the
pump station than it can pump. This pump station has the capacity to pump 3.8 million gallons
per day. When these overflows occurred, most of the sewage was being pumped to the
Wastewater Treatment Plant. The City of Henderson will need to investigate the cause of the
high flows in the sewer lines and establish a schedule for repairing/replacing the problem lines.
The Division is currently processing the collection system permit application and we plan
to include an enforceable compliance schedule for repair of the Sandy Creek Outfall line in the
permit.
In addition, the Redbud Outfall line had more severe sewer overflow problems. The City
is currently under a Special Order by Consent for repair of the lines and upgrade of the pump
station on this line. In February 2000, the City installed a large temporary pump to aid in the
transmission of sewage to the Wastewater Treatment Plant. No overflows from this pump station
have occurred since the installation of this pump. The Division of Water Quality is currently
reviewing Phase H of the schedule for this line. Construction for this Phase will include,
paralleling of the Redbud Outfall and permanently increasing the pumping capacity of the Red
Bud Pump Station.

Dear Mr. Williams:
It was brought to the attention of the Raleigh Regional Office (RRO), by Ms. Connie
Brower of the Division's Laboratory Certification Group, that reporting of replicate readings of
analytical results generated at the subject facility may not be consistently reported on the
Discharge Monthly Report (DMR). Ms. Brower indicated that repeated replicate testing was
being conducted on the same wastewater sample and that, in some instances, the analytical
results are not being averaged and reported on the DMR.
This is a violation of 15A NCAC 2B .0506 (J). Part (J) states "The results of all tests on
the characteristics of the effluent, including but not limited to NPDES Permit Monitoring
Requirements, shall be reported on monthly report forms. When replicate/duplicate readings are
performed, an arithmetic mean must be reported. Please ensure that all analytical data are
reported on the DMRs unless the data can be invalidated for legitimate reasons. Please contact
Ms. Connie Brower at 919-733-3908 and discuss the instances when it is appropriate to
invalidate data.

Subject: Compliance Evaluation Inspection
Nutbush Creek WWTP (Class IV Facility)
NPDES Permit NCO020559
Vance County
Dear Mr. Spain:
On March 30, 2001, Jenne Sowell and Joe Albiston of the Raleigh Regional Office
conducted a Compliance Evaluation Inspection of the City of Henderson's Nutbush Creek
WWTP (Class IV facility), assisted by Ms. Linda Leyen, Chief (Back-up) Operator in
Responsible Charge (ORC) and grade IV certified. Assistance during the laboratory inspection
was provided by Ms. Jennifer Anderson, Laboratory Supervisor & Pretreatment Coordinator.
Their assistance and cooperation were very helpful and appreciated. As a result of the
inspection, the following comments and/or recommendations were developed:
The current NPDES permit became effective October 1, 1997 and the authorization to
discharge expires April 30, 2002. You are reminded that a renewal application must be
submitted to the Division at least 180 days prior to the permit expiration. The facility has
a permitted flow of 4.14 MGD.
2. The wastewater treatment process consists of a bar screen, comminutor, mechanical grit
removal, parshall flume and influent flow meter, primary clarifiers, trickling filters,
secondary clarifiers, A/O process aerated nitrification basins, gaseous oxygen production
and liquid oxygen storage facilities, lime tower and feed, final clarifiers, tertiary filters,
activated carbon filters, dissolved air flotation sludge thickening, polymer feed station,
alum feed station, caustic feed station, pure oxygen aerobic digesters, anaerobic digesters,
standard aerobic digester, mechanically mixed sludge holding tank, UV disinfection and
sodium hypochlorite back-up, effluent flow meter, post aeration and discharge to Nutbush
Creek.

3. Mr. Thomas Spain (grade W) is the Operator in Responsible Charge (ORC) and Ms.
Linda Leyen (grade IV) is Chief Back-up ORC. James T. Alston and Sandy L. Clark are
also listed as Back-up ORC with the Division's Technical Assistance & Certification
Unit.
4. Granville Farms disposes of sludge generated from the facility. Please submit a record of
when sludge was hauled from the facility in 2000, and how compliance with the 503 regs
is accomplished.
5. The facility has a back-up generator that was operating at the time of inspection. The
generator is put under load weekly.
6. A review of laboratory and self -monitoring data (December 1999- December 2000)
submitted since the last inspection indicated the following:
(A) No omissions of monitoring requirements were noted.
(B) No violations of permit monthly limits or daily maximum limits were noted
(except toxicity, see # 8).
(C) A review of contract laboratory data sheets (from Tritest), chain of custody and
in-house laboratory bench sheets against the DMR for June 2000 revealed no
discrepancies. Meticuluous and accurate laboratory records are kept.
A cursory inspection of the ORC's records/reports indicated the following:
a) The ORC's daily logs are being maintained as required and were available for
inspection.
b) The facility's self -monitoring record, including analytical documentation, are
maintained and were readily available for inspection.
c) Calibration logs are well maintained and were readily available for inspection.
8. The failure of Quarterly toxicity monitoring during 1999 indicated possible problems
with the Town's SIU's/Pretreatment program. In response to these failures, RTA's have
recently been completed on two industries. During June 2000, the toxicity test failed
once again. Activated (virgin) carbon filters have been installed at the treatment plant
and the investigation into potential sources of toxicity continues. Calgon installs and
disposes of the activated carbon. The used carbon is stored on site in the drying beds.
Please provide an update regarding the status of toxicity testing at the plant.
9. The effluent flow meter was last calibrated on February 1, 2001 by in-house staff. It is
calibrated twice per year and Ms. Leyen stated that she performs weekly checks against
the staff gauge. Please be sure that each flow meter calibration is documented. Annual
calibration is required.
10. During the inspection, sludge depth in the clarifier was measured at 2' on the inside and
1' on the outside.

11. The temperature in the influent sampler was 8 degrees celcius and in the effluent sampler,
-1 degrees celcius (thermometer was submerged in glycerin which was not frozen).
Samplers should be kept at 0-4 degrees C without freezing. Please perform the necessary
repairs and/or adjustments to have all samples stored at the appropriate temperatures.
12. The effluent was clear with no noticeable odor, foam or solids in the receiving stream.
13. The effluent composite sampler is set up for flow proportional sampling, as required.
Please submit the rate of sample collection (ie: 150 ml per ??? gallons) The temperature
in the sampler was approximately -1.0 degrees celcius. Please correct the temperature
setting in the sampler so that samples will be stored at 0-4 degrees celcius (without
freezing).
14. Ms. Leyen stated that the plant has it's own maintenance department that is
responsible for repair and preventative maintenance to the wwtp (all units and
machinery). A routine preventative maintenance schedule is followed which includes
weekly cleaning of the clarifier weirs. Some spare parts are stored on site.
15. The on -site chemistry laboratory is certified, as required, by DWQ. (Certification # 242)
Two lab technicians collect samples and an on -site Chemist performs in-house analyses.
The laboratory appeared well maintained and organized. Containers were properly
labeled with receipt and open dates. Expired pH buffers were discarded and current
solutions were available.
16. At the time of inspection, influent flow meter read approximately 8.0 MGD (facility's
permitted capacity = 4.14. MGD). Ms. Leyen called DWQ on the evening of March 29
to report a bypass before the UV light unit. Overflow occurred due to heavy rains and
Inflow& Infiltration. Please submit a summary of activity performed in 2000 to
eliminate/reduce inflow and infiltration in the collection system, and what is planned for
2001.
17. The Redbud Pump Station is currently scheduled for repair. This pump station has a
history of frequent overflows. Please provide a summary of the status of this project and
any other relevant information regarding repairs to the collection system.
The plant appears to be well maintained and operating satisfactorily. Please respond to

Description of Collection System or Treatment Process: r-)T —aG
The treatment plant is designed for a flow of 4.14 million gallons per day of wastewaA R ro
and receives an average of 2.81 million gallons per day. The plant treated 1,022,0001000 (a 16l �o
d 'c�
billion twenty two million gallons from July 1, 1999 to June 30, 2000. m
The treatment process consists of rag and grit removal, primary clarification, two stage y
trickling filters, intermediate clarification, pure oxygen activated sludge, final clarification
filtration, post aeration and ultraviolet disinfection.
The treatment plant biosolids are applied at agronomic rates to farmland by a private
contractor, Granville Farms, Inc.
The collection system consists of approximately one hundred forty (140) miles of gravity
sewer and force main lines and thirteen (13)-pumping stations that convey the wastewater to the
treatment plant.
IL Performance Summary
The Nutbush Creek Wastewater Treatment Plant was in compliance with all permit
limits during this performance period except chronic toxicity for the months of October,
November, and December of 1999 and January and June of 2000 and received notices of
violation for these months. The City has made extensive efforts and taken immediate steps to
remedy the matter. Activated carbon was installed at the plant in July 2000 and is
successfully removing the toxicity.

There was no known environmental damage from the toxicity violations. The failed
samples were close to passing and our limit is based on a May low flow in 10 years. The
flow in Nutbush Creek during this reporting period was considerable above this flow.
The Nutbush Creek Wastewater Treatment Plant biosotids were applied to farmland at
agronomic rates and met all permit conditions.
The Nutbush Creek Wastewater Treatment Plant Laboratory received twenty-three (23)
violations during an inspection by the State Division of Water Quality in September 1999. Seven
(7) of the violations were documentation errors only. The City takes any violation seriously
and all of these violations were corrected immediately and a report was provided to the
State documenting the corrections within 6 weeks of the inspection.
The City believes that we are turning out quality data in our laboratory. We performed
all of the last EPA and State Ouality Control Samples in acceptable ranee. These are
samples sent to laboratories to perform with only the EPA and State knowing the values.
The Nutbush Creek Wastewater Treatment Plant was issued a Notice of Violation of the
Pretreatment Program by the State Division of Water Quality in April 2000 for failure to perform
chronic toxicity tests for the fourth (e) quarter of 1999 at several industries and failure to collect
a representative sample at one industry in December 1999.
These violations were issued in error by the State as indicated by the explanations
below and by a June 23 , 2000 State Pretreatment Compliance Inspection Report that stated "All
SIUs were sampled according to the POTW's sampling schedule during the last calendar
year (1999)."
The City informed the State that the December 1999 testing was invalid due to a private
contract laboratory error and the test had been made up in February 2000.
The representative sample at one industry was used to condition a reactor and did not
have to meet State protocol. The monitoring sample collected the following day did meet
protocol.
The Nutbush Creek Wastewater Treatment Plant bypassed the ultraviolet disinfection unit
three (3) times in September 1999 and two (2) times in March 2000. A total of 996,500 gallons
received all treatment except disinfection before discharge into Nutbush Creek. The bypasses
were a result of one equipment failure and flows that exceeded the plant capacity during heavy
rainfall. The City is in the design stage of upgrading the plant's capacity to prevent
bypasses during heavy rainfall.
The Nutbush Creek Wastewater Treatment Plant Collection System (pump station and
gravity and/or force main lines) bypassed a total of 4,482,410 (four million four hundred eighty
two thousand four hundred ten) gallons of untreated sewage between July 1, 1999 and June 30,
2000. The total gallons bypassed was only 0.4% of the total 1,022,000,000 (one billion
twenty two million gallons) treated during this annual report period.

Sixty-six (66) percent of the bypasses occurred during September as a result of the
hurricane and associated rainfall and twelve (12) percent occurred during the two weeks
following the 20-inch snowfall the last week of February 2000.
In all 78% of the bypasses were a direct result of extreme and unusual weather
conditions.
There were twenty (20) bypasses of the pump stations and nineteen (19) bypasses of the gravity
lines. Most of the bypasses were the result of heavy inflow and infiltration from rainfall
exceeding the system capacity or blockage of the lines with grease and rags.
The City has already installed a portable pump at Red Bud Pump Station and
stopped all bypasses at this station since 2-8-00 and has a construction project planned to
upgrade the Red Bud Pump Station. The design of the Sandy Creek Pump Station upgrade
should be completed by the end of 2001.
The City also plans to implement a grease trap permitting and maintenance program for
all restaurants and cafeterias discharging to the collection system.
There was no known environmental damage from the bypasses. No death of fish or other
aquatic fife was observed.

Response: Lab staff has been instructed to analyze a midpoint check standard for each
metal after the last sample.
(23) Violation: Lab is not meeting required frequency for duplicate samples for this analysis.
Response: The frequency for duplicate samples was not being met due to the fact
when less than 10 samples were being run in one batch analyst did not think he
needed to duplicate. Duplicates were only performed when there were more than 10
samples in a run. Lab staff has been instructed to run duplicates in every batch run.
(24) Violation: The copper furnace data was reported at the incorrect reporting limit.
Response: Lab staff instructed to verify all calibration curves and to highlight the
lower reporting standard on each run.

Land Application of Wastewater Residuals Permit Held by
Private Contractor (Granville Farms, Inc.) WO 0000838
Description of Collection System or Treatment Process:
The treatment plant is designed for a flow of 4.14 million gallons per day of wastewater
and receives an average of 2.81 million gallons per day. The plant treated 1,022,000,000 (one
billion twenty two million gallons from July 1, 1999 to June 30, 2000.
The treatment process consists of rag and grit removal, primary clarification, two stage
trickling filters, intermediate clarification, pure oxygen activated sludge, final clarification,
filtration, post aeration and ultraviolet disinfection.
The treatment plant biosolids are applied at agronomic rates to farmland by a private
contractor, Granville Farms, Inc.
The collection system consists of approximately one hundred forty (140) miles of gravity
sewer and force main lines and thirteen (13)-pumping stations that convey the wastewater to the
treatment plant.
H Performance Summary
The Nutbush Creek Wastewater Treatment Plant was in compliance with all permit
limits during this performance period except chronic toxicity for the months of October,
November, and December of 1999 and January and June of 2000 and received notices of
violation for these months. The City has made extensive efforts and taken immediate steps to
remedy the matter Activated carbon was installed at the plant in July 2000 and is
successfully removing the toxicity.

There was no known environmental damage from the toxicity violations. The failed
samples were close to passing and our limit is based on a 7day low flow in 10 years. The
flow in Nutbush Creek during this reporting period was considerable above this flow.
The Nutbush Creek Wastewater Treatment Plant biosolids were applied to farmland at
agronomic rates and met all permit conditions.
The Nutbush Creek Wastewater Treatment Plant Laboratory received twenty-three (23)
violations during an inspection by the State Division of Water Quality in September 1999. Seven
(7) of the violations were documentation errors only. The City takes any violation seriously
and all of these violations were corrected immediately and a report was provided to the
State documenting the corrections within 6 weeks of the inspection.
The City believes that we are turning out quality data in our laboratory. We performed
all of the last EPA and State Ouality Control Samples in acceptable ran¢e. These are
samples sent to laboratories to perform with only the EPA and State knowing the values.
The Nutbush Creek Wastewater Treatment Plant was issued a Notice of Violation of the
Pretreatment Program by the State Division of Water Quality in April 2000 for failure to perform
chronic toxicity tests for the fourth (4's) quarter of 1999 at several industries and failure to collect
a representative sample at one industry in December 1999.
These violations were issued in error by the State as indicated by the explanations
below and by a June 23` , 2000 State Pretreatment Compliance Inspection Report that stated "All
SIUs were sampled according to the POTW's sampling schedule during the last calendar
year (1999)."
The City informed the State that the December 1999 testing was invalid due to a private
contract laboratory error and the test had been made up in February 2000.
The representative sample at one industry was used to condition a reactor and did not
have to meet State protocol. The monitoring sample collected the following day did meet
protocol.
The Nutbush Creek Wastewater Treatment Plant bypassed the ultraviolet disinfection unit
three (3) times in September 1999 and two (2) times in March 2000. A total of 996,500 gallons
received all treatment except disinfection before discharge into Nutbush Creek. The bypasses
were a result of one equipment failure and flows that exceeded the plant capacity during heavy
rainfall. The City is in the design stage of upgrading the plant's capacity to prevent
bypasses during heavy rainfall.
The Nutbush Creek Wastewater Treatment Plant Collection System (pump station and
gravity and/or force main lines) bypassed a total of 4,482,410 (four million four hundred eighty
two thousand four hundred ten) gallons of untreated sewage between July 1, 1999 and June 30,
2000. The total gallons bypassed was only 0.4% of the total 1,022,000,000 (one billion
twenty two million gallons) treated during this annual report period.

Sixty-six (66) percent of the bypasses occurred during September as a result of the
hurricane and associated rainfall and twelve (12) percent occurred during the two weeks
following the 20-inch snowfall the last week of February 2000.
In all 78% of the bypasses were a direct result of extreme and unusual weather
conditions.
There were twenty (20) bypasses of the pump stations and nineteen (19) bypasses of the gravity
lines. Most of the bypasses were the result of heavy inflow and infiltration from rainfall
exceeding the system capacity or blockage of the lines with grease and rags.
The City has already installed a portable pump at Red Bud Pump Station and
stopped all bypasses at this station since 2-8-00 and has a construction project planned to
upgrade the Red Bud Pump Station. The design of the Sandy Creek Pump Station upgrade
should be completed by the end of 2001.
The City also plans to implement a grease trap permitting and maintenance program for
all restaurants and cafeterias discharging to the collection system.
There was no known environmental damage from the bypasses. No death of fish or other
aquatic life was observed.

(14) Violation: The second page of the worksheets was not signed by the analyst.
Response: Date, Time, & Analyst initials have been added to second page of COD
worksheet. Lab staff has been instructed to document both sheets properly.
Fecal Coliform - MF
(15) Violation: Errors are marked incorrectly on the Fecal Coliform data of 7/27/99.
Response: Lab staff has been instructed when an error is made, cross out the mistake
with one ink line, place the correction next to the error along with the date and analyst's
initials.
Chloride
(16) Violation: No daily check standard was analyzed and documented on the worksheets.
Response: Lab staff has been instructed to run a check standard every analysis. "Run a
Known Standard every analysis" has been added to the chloride bench sheet as a
reminder for analysts.
Specific Conductivity
(17) Violation: A series of standards were not analyzed to bracket the range of samples on
each analysis day.
Response: The lab will bracket the range of all samples for analysis. New conductivity
standards of 100, 200, 500, 1000, 2000, & 5000 have been purchased from Reagents, Inc
in order for the lab to establish the proper range for analysis. A copy of the requisition is
enclosed.

Oil & Grease
(18) Violation: No vacuum or air stream was applied to the flask for at least 60 seconds.
Response: An air stream will be applied to the flask for at least 60 seconds after every oil
& grease analysis.
Total Residue
(19) Violation: The total residue drying study was not available for review during inspection.
Response: The total residue drying study was performed 10/27/99. A copy of the study
is enclosed.
(20) Violation: Insufficient effluent sample was analyzed to have at least 10 mg of residue in
the dish.
Response: Effluent sample used for total solids have been doubled (25 ml to 50 MI) to
yield at least 10 mg of residue in the dish. As a reminder for analyst the phrase "analyze
sufficient sample to yield at least 10 mg (0.01 g) of dry residue" has been added to the
total solids bench sheet.
Metals
(21) Violation: The expiration date of the older stock standards had passed.
Response: These stock standards have been labeled with "Expire. Do not used." These
standards have been boxed up until they can be properly disposed of.

sample.
Response: Lab staff has been instructed to analyze a midpoint check standard for each
metal after the last sample.
(23) Violation: Lab is not meeting required frequency for duplicate samples for this analysis.
Response: The frequency for duplicate samples was not being met due to the fact
when less than 10 samples were being run in one batch analyst did not think he
needed to duplicate. Duplicates were only performed when there were more than 10
samples in a run. Lab staff has been instructed to run duplicates in every batch run.
(24) Violation: The copper furnace data was reported at the incorrect reporting limit.
Response: Lab staff instructed to verify all calibration curves and to highlight the
lower reporting standard on each run.

I am writing in response to the Notice of Violation for effluent toxicity limitation for the City of
Henderson's Nutbush Creek WWTP that was issued for the month of June, 2000 by Mr. Kenneth
Schuster, PE, Raleigh Regional Water Quality Supervisor.
The City of Henderson furnished a quarterly toxicity reduction evaluation report to the State
DWQ on August 15, 2000.
Activated carbon was installed on the tertiary filters the third week of July and the July toxicity test
was > 100%.
The August toxicity test was invalid for the week of August 14, 2000 because of control problems
and has been rescheduled for the week of August 28, 2000.
The City is continuing to search for what appears to be a new source of toxicity in a commercial
line from the north side of town. Extensive toxicity testing of the line is scheduled for the week of
August 28, 2000.

April 2000 showed no limit and/or monitoring violations except toxicity.
3. The current permit expires April 30, 2002. You are reminded to submit an
application to renew the permit prior to 180 days of the expiration date.
4. Sludge from the facility is handled by Granville Farms through permit number
WQ0000838.
5. Mr. Spain stated that the Town has 12 pump stations. The Town has generators at
5 of these stations and a telemetry system for each station to prevent overflows and
possible environmental damage that the Town would be liable for that result from
such overflows.
6. Effluent composite samplers must be programmed to collect samples flow
proportionally as specified in Part H 8a. of the NPDES permit immediately. Please
submit documentation that this has been completed. Failure to properly collect
samples is a violation of the NPDES permit, as is subject to enforcement action by ......

NUfBUSH CREEK WASTEWATER
TREATMENT PLANT
March 24`h, 2000 Notice of Violation
In response to Mr. Schuster's March 24, 2000 Notice of Violation of effluent toxicity,
offer the following response:
1. Even though the chronic toxicity results of Henderson's WWTP were 77.9% for
October, November, December and January, several of these tests were very close to
passing.
2. The chronic toxicity results were >90% for both February and March and we should
have the results for April by April 14, 2000.
3. The City thinks the chemical optimization and chemical substitution at Americal and
the sealing of equipment wash pits at Harriet and Henderson Yarns South Henderson
Cotton Mill have reduced toxicity entering the WWTP.
4. The City is aggressively requiring additional chemical testing at Americal and
issuing a NOV, permitting and requiring RTA work at the South Henderson Cotton
Mill..
The City is conducting granular activated carbon testing of the W WTP effluent for
toxicity removal with the assistance of McKim and Creed and Aquatic Sciences
Consulting.
6. In addition, Americal and the South Henderson Cotton Mill are being tested twice per
week for toxicity with our Microtox unit.

The results for the past 60 days indicates little or no toxicity being discharged from these
facilities.
If you need further information, please contact me at 252-431-6081.

➢ Toxicity test results shall be filed with the Environmental Sciences Branch no later than 30 days after the end
of the reporting period (eg, January test result is due by the end of February).
➢ Toxicity test condition language contained in your NPDES permit may require use of multiple concentration
toxicity testing upon failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic
value is lower than the permit limit, then at least two multiple concentration toxicity tests (one per month) will
be conducted over the following two months. As many analyses as can be completed will be accepted. If your
NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single
quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration
toxicity testing per the Divisions WET enforcement initiatives effective July 1, 1999. Follow-up multiple
concentration toxicity testing will influence the Division's enforcement response.
➢ Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic
toxicity monitoring requirements (eg, if the testing months specified in your NPDES permit are March, June,
September, and December, then toxicity testing must be conducted during these months).

I am responding to a notice of violation of effluent toxicity limits for the City of
Henderson's WWI? for the month of December, 1999 that was received from Mr. Ken
Schuster, Raleigh Regional Water Quality Supervisor.
The City is aware of toxicity violations at our WWI? and have attempted to obtain an
extension of our SOC from the DWQ but have not received a response to our request yet.
We have continued to conduct a THE (toxicity reduction program) and submitted our last
quarterly report to the DWQ on February 15`s, 2000 that gave a detailed account of the
actions we are taking to solve the toxicity problem.
We are requiring Harriet and Henderson Yams Inc. to conduct a THE and RTA
(refractory toxicity assessment) of their discharge, which was detected to be toxic.
Americal Inc. checked nontoxic during recent RTA tests after making chemical and
process changes in their operation, but the City plans additional follow-up tests to verify
their toxicity problem is solved.

0 a
We are working with Aquatic Sciences Consulting and Mckim & Creed to conduct pilot
bench scale tests to evaluate activated carbon's ability to remove toxicity and the best
way to install this treatment at the W WTP.
In addition, we are continuing to use our Microtox unit to monitor the toxicity of the
discharges of key industries on a weekly basis with the intent of discovering the source(s)
and/or identifying the toxicant(s) and eliminating them.
The City would welcome any input from the DWQ on how to find and resolve our
toxicity problem. We have expended a tremendous amount of resources both financially
and in man hours trying to solve the toxicity problem, but it has been the most difficult
problem to identify and solve that the City has ever encountered with its wastewater
treatment system.
We have a solid record of solving compliance problems that we can identify. Past
noncompliance problems with BOD, NH3-N, Cadmium, Mercury, MBAS, Chromium,
Phosphorus, Lead, etc. have all been resolved and we would have already resolved the
toxicity problem(s) if we had been able to identify and/or locate all them.
The City again requests that the DWQ notify us of the status of our request for an SOC
extension for toxicity.
I am forwarding revisions of ages #4 and # 5 for our February 15a' quarterly toxicity
report for your review.
Some of the IC 25 values needed to be corrected.
If you need further information, you can contact me at 252-431-6081.

> Toxicity test results shall be filed with the Environmental Sciences Branch no later than 30 days after the end
of the reporting period (eg, January test result is due by the end of February).
➢ Toxicity test condition language contained in your NPDES permit may require use of multiple concentration
toxicity testing upon failure of any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic
value is lower than the permit limit, then at least two multiple concentration toxicity tests (one per month) will
be conducted over the following two months. As many analyses as can be completed will be accepted. If your
NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single
quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration
toxicity testing per the Division's WET enforcement initiatives effective July 1, 1999. Follow-up multiple
concentration toxicity testing will influence the Division's enforcement response.
➢ Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic
toxicity monitoring requirements (eg, if the testing months specified in your NPDES permit are March, June,
September, and December, then toxicity testing must be conducted during these months).
➢ If your NPDES Permdt specifies episodic monitoring and your facility does not have a discharge from January 1-
June 30, then you must provide written notification to the Environmental Sciences Branch by June 30 that a
discharge did not occur during the first six months of the calendar year.
D If you receive notification from your contract laboratory that a test was invalidated, you should immediately
notify the Environmental Sciences Branch at [phone] and provide written documentation indicating why
the test was invalidated and the date when follow-up testing will occur.
➢ If your facility is required to conduct toxicity testing during a month in which no discharge occurs, you should
complete the information block located at the top of the AT form indicating the facility name, permit number,
pipe number, county and the month/year of the subject report. You should also write "No Flow" on the AT
form, sign the form and submit following normal procedures.
➢ The Aquatic Toxicity Test forms shall be signed by the facility's Operator in Responsible Charge (ORC) except
for facilities which have not received a facility classification. In these cases, a duly authorized facility
representative must sign the AT form. The AT form must also be signed by the performing lab supervisor.
➢ To determine if your AT test forms were received on time by the Division of Water Quality, you may consider
submitting your toxicitytest results certified mail, return receipt requested to the Environmental Sciences
Branch.

In December, tests were performed to evaluate the contribution of toxicity in the Sandy Creek
sewershed and the Redbud main line. The toxicity tracking was performed to evaluate the
primary sources of toxicity in the Sandy Creek sewershed (i.e., Americal and the Harriet &
Henderson cotton mills). Americal's RTA test was performed by Americal as required under
their industrial user permit.
RTA results are stunmarized in Table 2 and Figure 1 (full report is included in Appendix B).
Once again, the Sandy Creek pump station was found to be discharging refractory toxicity. As
shown by the inhibition concentration (IC25) results, the Sandy Creek pump station flow was
more toxic than the control effluent (i.e., 37.6 vs. 50.0%). The 95% confidence intervals for the
IC25 values do not overlap; therefore, the pump station sample contained significant refractory
toxicity. Significant refractory toxicity has been repeatedly observed at the Sandy Creek pump
station (most recently in July).
Of the three discharges evaluated in the Sandy Creek sewershed, the Harriet & Henderson south
cotton mill appeared to be contributing to the observed toxicity at the Sandy Creek pump station.
The effluent of the south mill reactor was more toxic than the control (IC25s of 33.1 vs. 50.0%,
respectively). The toxicity is significant given that the confidence intervals for the IC25 values
do not overlap. These results confirm the results of RTA tests performed in September, which
indicated the south cotton mill to be a source of refractory toxicity. Harriet & Henderson's north
cotton mill was not found to be a source of toxicity.

Figure 1. Comparison of Chronic Toxic Unit (TUc) Values for December RTA Tests
Americal's discharge did not appear to contain refractory toxicity when tested at both 6.4% and
8.0% in the RTA. The addition of Americal's discharge samples to the mock W WTP influent
actually decreased toxicity relative to the mock influent alone (i.e., 75.1 and 69.1% vs. 50.0%,
respectively). These results show that Americal was not contributing refractory toxicity on
December 6 h - 8`�.
The RTA control test, which is designed to simulate the city's W WTP, continues to treat toxicity
less effectively than the W WTP. A relatively high level of refractory toxicity was observed in
the control test (IC25 = 50.0) as compared to the WWTP effluent (IC25 >90%). It is unclear
why this difference was observed, particularly after the steps taken to minimize toxicity
interferences in the RTA. In the December RTA, a "nontoxic" activated sludge was developed to
use in lieu of the W WTP activated sludge, which has been shown to harbor toxicity. Possible
reasons for poor toxicity treatment are that (1) the bioreactor used to develop the nontoxic
biomass was not operated long enough to purge toxicity and (2) the "domestic" influent (North
Nutbush line) sample used in the RTA was toxic. The city is in the process of evaluating another
nontoxic domestic wastewater for use in developing nontoxic biomass and for use in the RTA as
the domestic influent.

sewage bypass
Redbud Station
fiet weather creates
inwanted discharge
Df excess sewage
ByBARBARA ARNTSEN
DAILY DISPATCH WRITER
Wet weather brought another
discharge of excess sewage flow•
[ng around the Redbud pumping
Station last week.
Heavy rains Monday, January
10, forced approximately
165,000 gallons of untreated
wastewater from the station
into the nearby Redbud Creek.
The creek flows into the Tar -
Pamlico River Basin.
The troubled station, located
at the intersection of 158
Business and Vance Academy
Road, is operating under a
Special Order of Consent from
the state until the year 2002.
According to Wastewater
Treatment Plant Director Tom
Spain, the station has to bypass
every time the area experiences
a major downpour. The bypass is
caused by inflow and infiltration
from heavy rainfall that exceeds
the station's pumping capacity.
The latest discharge began
around 11 a.m. Jan. 10 and con-
tinued until 11:30 p.m. Saturday.
Spain said that none of the
sewage had spilled into anyone's
yard.
"If there was a leakage or spill
in someone's yard from this we
would put lime on it to disinfect,
but that is not happening with
this. There is no spill in anyone's
yard. Any entrance point would
be on city property and it goes
straight to the creek."
The station also experienced a
bypass in mid -December. Area
