Subject: Issuance of NPDES Permit NC0020559
City of Henderson WRF
Vance County
Dear Mayor Young:
Division staffi have reviewed and approved your renewal application for an NPDES discharge permit.
Accordingly, the Division is forwarding the subject NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently
amended).
In response to the City of Henderson's letter dated September 17, 2002 we offer the following comments:
• Treatment units - The description of the treatment system was modified to add the units that were not
listed.
• Dissolved Oxygen - The dissolved oxygen limit footnote was modified to read "daily average dissolved
oxygen effluent concentration".
• Metals monitoring — Monitoring for chromium and lead were eliminated from the permit as you
requested. These parameters still must be monitored quarterly for the Long Term Monitoring Plan. The
results foiT lead have been below detection levels for more than twelve months of sampling. The results
for chromium were generally non -detect or less than half the allowable concentration.
• Chronic Toxicity — The information in Section A. (4) of the permit represents the current method for
chronic toxicity tests. In answer to your question regarding monthly tests results of 80% the first month,
80% the second month and 100% the third month, the first two months will be considered non-
compliant and the third month would be considered compliant. If you have any questions concerning
compliance with Whole Effluent Toxicity requirements please call Mr. Matt Matthews of the Aquatic
Toxicity Unit at [phone].
• Effluent Pollutant Scan — The requirement to perform the pollutant scan can't be removed from the
permit. This requirement is part of the federal regulations for POTW and is being implemented in all
major permits. To meet the seasonal variation requirement samples should be collected in a different
calendar quarters each year. A copy of the form (DMR-PPA-1) to report the results from the effluent
pollutant scan is included. Two copies of the form should be submitted to Central Files attached to the
monthly DMR.
• Mercury Compliance with metal limits, including mercury, will continue to be evaluated as it has been
in the past. The Division's policy is to impose a fine of $250.00 when the limit is exceeded by 20% or
more. If ,you have any questions concerning compliance and enforcement please contact Mr. Shannon
Langley„Supervisor of the Point Source Compliance and Enforcement Unit at [phone], extension
516.

This final permit includes weekly average limits for ammonia. The U.S. EPA required the Division to
develop a policy by October 2002 to implement weekly average ammonia limits for municipal facilities. The
weekly average limit is established based on a ratio of 3:1 (weekly average : monthly average). The
corresponding weekly average limits in your permit are 9.0 mg/L for the summer and 18.0 mg/L for the
winter for the flow of 4.14 MGD and 6.0 mg/L for the summer and 12.0 mg/L for the winter for the flow of
6.0 MGD.
If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable to
you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following
receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of
the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service
Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and
binding.
This permit is not transferable except after notice to the Division. The Division may require modification or
revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality, the Division of Land Resources, the Coastal
Area Management Act, or any other federal or local governmental permit.
If you have any questions concerning this permit, please contact Teresa Rodriguez at telephone number (919)

3. Composites shall be collected as spatial composites throughout the photic zone (i.e. two times the
secchi depth.)
As per 15A NCAC 2B.0505 (c) (4), stream sampling may be discontinued at such time as flow
conditions in the receiving waters or extreme weather conditions will result in a substantial risk of
injury or death to persons collecting samples. In such cases, on each day that sampling is
discontinued, written justification for the discontinuance shall be specified in the monitoring report for
the month in which the event occurred. This provision shall be strictly construed and may not be
utilized to avoid the requirements of 15A NCAC 2B.0500 when performance of these requirements is
attainable. When there is a discontinuance pursuant to this provision, stream sampling shall be
resumed at the first opportunity after the risk period have ceased.
A (4) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, Quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.

Permit NC0020559
,
The chronic value I for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for tle pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3
(original) is to be sent to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. 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 the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
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.

Matt,
Henderson submitted written comments regarding their draft permit, two
of them are on the toxicity limit. Could you evaluate their comments and
let me know how to respond to them, I will respond to all their comments
in the issuance letter.
Their comment! are:
A. The chromic toxicity limit (Section A(3)) states that "The chronic
value for multiple concentration tests will be determined using the
geometric mean of the highest concentration having no detectable
impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival." Is this
the approved method presently being used? Our contract lab does the
calculations for our multiple range chronic tests.
B. Our chronic toxicity limit is 90 %. How will compliance be
determined if we have the following results:?
The first month of the quarter we have a 80 % chronic value. The result
for month two is 80 % and month three is 100 %.
Thanks,
Teresa
Teresa,
The answer to question A is yes.
The answer to qu tion B is that the test results from each of the first two months would be considered
noncompliant and the test result from the third month would be considered compliant.
Please call if you have questions,

Marshall:
I did the reasonable potential for both flows but only attached the one for
4.14 MGD to the fact sheet. The spreadsheet for the RPA for both flows•is
attached.
They didn't provide analysis for the parameters they reported as present.
I'm waiting for the results of the priority pollutant analysis that should
include those. I found some data for nickel from pre-treatment that I
added to the rpa and it shows reasonable potential but based on only five
data points. I asked them if they have any more data for nickel and they
are looking into it. If I get more information from them I will reevaluate
the RPA, otherwise I'll add the limit.
I will follow up with the information regarding nickel and the results of
the PPA as soon as I get it.
Thanks,
Teresa

RE: Review and Comments
NPDES Draft Permit
Permit # NC0020559
City of Henderson Water Reclamation Facility
Vance Co.
Dear Ms. Rodriguez,
After review of the new draft NPDES Permit for the City of Henderson Water
Reclamation Facility, I have the following comments:
NUTBUSH CREEK WASTEWATER
TREATMENT PLANT
1. The description of the plant components on the supplemental cover sheet left off two
units (anaerobic digesters and standard aerobic digester).
2. The dissolved oxygen limit in the draft permit states (Item #7 of notes) "the daily
effluent dissolved oxygen concentration should not be less than 6.0 mg/1. The
present permit limit has daily average and I request to change the draft permit limit to
a daily average for both the 4.14 MGD and 6.0 MGD flows.
3. I request that effluent monitoring be dropped for the following metals:
A. Lead:
A review of our DMR monitoring data indicated one result of 21.0 ug/1 in
January, 2001 with all other results being below our detection level of 10 ug/1
since September, 2000 (past 2 years). We had 95 out of 96 samples below
detection level.

B. Chromium
The results ranged from below detection (used to be 1 ug/1 and now 2 ug/1) to a
maximum of 13.8 ug/1 in September, 2001. The highest result is only 27.6 % of
the 50 ug/1 stream standard.
4. A. The chronic toxicity limit (section A (3) states that "the chronic value for multiple
concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction and survival and
the lowest concentration that does have a detectable impairment of
reproduction or survival ". Is this the approved method presently being used? Our
contract lab does the calculations for our multiple range chronic tests.
B. Our chronic toxicity limit is 90%. How will compliance be determined if we have
the following results?:
The first month of the quarter we have a 80% chronic value. The results for
month two is 80% and month three is 100%.
C. In 'a letter from you dated July 18, 2002 you said in item #4 "a second species's
chronic toxicity test" is required to complete our permit renewal process. Is this
still required? There was no mention of a second species toxicity test in our draft
permit. I certainly don't request a parameter not required by the state DWQ but I
also don't want it added in as a surprise amendment either. What is the state
DWQ's position on this requirement?
5. A. I request that section A (4) effluent pollutant scan be deleted from our permit. I
realize (from previous discussions that) the state doesn't want to add this
monitoring and sees no environmental benefit from it. The only reason it is being
added is because EPA is requiring that it be done. We have a strong pretreatment
program that tracks and controls pollutants of concern. This extra testing is an
unfunded mandate at a time when the state has withheld funds from local
governments creating severe budget problems state wide. What environmental
benefit does the state DWQ anticipate from adding the effluent pollutant scan to
the City of Henderson's NPDES permit?
B. If the effluent pollutant scan remains in our NPDES permit then I request a
schedule be added when these tests should be performed. The present schedule
states "the total set of samples analyzed during the current term of the permit must
be representative of seasonal variations". This is too vague. At present, the
NPDES monitoring is set up as winter and summer limits. If this what you mean
by seasonal or do you mean spring, summer, fall and winter? The schedule should
be established in the permit so there is no question when the state wants these tests
performed.

C. Please furnish a copy of DWQ Form DMR-PPA1 to the City of Henderson or
provide the web site where it can be obtained.
D. Normally it is required that two copies of the DMR be submitted to Central Files.
The instructions for DMR-PPA1 require one copy be submitted to the NPDES
Unit and one to the Compliance and Enforcement unit. Are these the only two
copies required and can they be mailed in one envelope since the address for both
units is the same?
6. The proposed permit requires that the new EPA method 1631 be used to analyze
mercury beginning September 1st, 2003. This will in effect lower the permit limit
from the previous detection level of 0.2 ug/1 to 0.012 ug/1 or 16.7 times lower. The
clean sampling techniques and test requirements to meet this level will be very
expensive. Someone who has amalgam fillings in his/her teeth can not even breath
in the direction of the sample or it will be contaminated. How will the state DWQ
handle enforcement and fines for mercury under this new testing requirement? The
previous fine was an automatic $250.00 for every violation but the sample was a 24
hour composite and not a one shot grab.
Thank you for your consideration of these requests. I know you and the permitting staff
have worked hard to draft an environmentally sound permit for the City of Henderson's
Water Reclamation Facility.
Sincerely,
lam

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.
Both changes arel 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, $fudge holding tank and sludge drying bed.
Basin Plan Thepl 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
(LIMP) or 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.

The permit also includes monitoring for temperature, total nitrogen, conductivity, chromium, silver,
zinc and copper.
Whole Effluent Toxicity (WET) - The permit requires a ceriodaphnia chronic toxicity pass/fail 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:

Instream Data Review — Henderson monitors the receiving stream at one location upstream and at
two locations downstream. Data was reviewed for the period of January 2000 to December 2001.
The upstream station shows frequent fecal coliform levels above the standard, the two downstream
stations show only occasional coliform levels above 200 #/100 ml. Chlorophyll -a was below the
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 monthly.
• 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.

This letter is to notify you that the Environmental Protection Agency (EPA) Region 4,
will need additional time to complete our review of the draft National Pollutant Discharge
Elimination System (NPDES) permit dated August 7, 2002, for the City of Henderson Water
Reclamation Facility, NC0020559, which was received by EPA Region 4 on August 14, 2002.
In accordance with the North Carolina/EPA Memorandum of Agreement (MOA) and federal
regulations, EPA Region 4 may use up to the full 90-day review period from the date the draft
was received, provided by 40 CFR § 123.44(a), to review this draft NPDES permit. EPA, Region
4, will make every effort to provide any comments or objections well before November 12, 2002,
when the 90-day review period ends.
This extension is needed to give the EPA enforcement staff time to review and comment
on the Special Order by Consent, EMC SOC WQ 96-005, for the City of Henderson, North
Carolina which directly affects the City of Henderson Water Reclamation Facility. This has been
discussed with your staff permit writer. If you have any further questions, please have your staff
contact Marshall Hyatt of my staff at 404/562-9204.

PART IV - EVALUATION AND RECOMMENDATIONS
THIS FACILITY IS A BIOLOGICAL AND CHEMICAL TREATMENT PLANT FOR
THE CITY OF HENDERSON'S WASTEWATER. THE DISCHARGE IS TO NUTBUSH
CREEK WHICH FLOWS INTO KERR LAKE. IT WAS NOTED THAT THE TOTAL
PHOSPHORUS LIMIT CHANGES FROM 1.0 MG/L TO 1.5 MG/L IN THE WINTER
MONTHS. I DO NOT UNDERSTAND THE REASON FOR THE TWO LIMITS SINCE,
ACCORDING TO THE PERMIT RENEWAL, PHOSPHORUS REMOVAL IS
ACCOMPLISHED BY CHEMICAL ADDITION OF ALUM IN FINAL
CLARIFICATION AND DOES NOT RELY ON BIOLOGICAL REMOVAL. IT IS
ALSO NOTED THAT AT EXPANSION ABOVE 4.14 MGD THE PHOSPHORUS
LIMIT WILL BE 0.5 MG/L YEAR ROUND. AT THIS PERMIT RENEWAL, THE RRO
Discharge Staff Report
Page 4

RECOMMENDS THAT THE MOST RECENT DIVISION TOXICITY PERMIT
BE INCORPORATED. THE RRO ALSO RECOMMENDS THAT THE
PERMIT .TO DISCHARGE BE RENEWED IN ACCORDANCE WITH ALL DIVISION
POLICIES AND REGULATIONS AND CURRENT BASIN PLANS.

Comments: All LTMP data is reported on the DMR, except for nickel. Henderson stopped testing for Ni when
it was dropped from their NPDES permit. It is still required in their LTMP and would not be
approved to drop Ni from the list of POCs. I am going to require that they do weekly influent and
effluent Ni sampling for 4 weeks, to be completed no later than 4/12/02 and submit the results no
later than 5/3/02. I will forward those to results to you as soon as I receive them.

Comments: All LTMP data is reported on the DMR, except for nickel. Henderson stopped testing for Ni when
it was dropped from their NPDES permit. It is still required in their LTMP and would not be
approved to drop Ni from the list of POCs. I am going to require that they do weekly influent and
effluent Ni sampling for 4 weeks, to be completed no later than 4/12/02 and submit the results no
later than 5/3/02. I will forward those to results to you as soon as I receive them.

Dave,
I have one more item I'd like to address in our NPDES Permit renewal. I
would like to change the name of the facility on the permit to "City of
Henderson Water Reclamation Facility". There seems to be a trend by many
cities to rename the wastewater treatment plants because so many people
consider a facility is a polluter when they see or hear the name wastewater.
Please let me know if this can be done during the permit renewal and if I
need to notify other sections such as the State Lab or will this be handled
internally by the State to keep the data base in tack?
Thanks Much Tom Spain

Tom,
Things are going relatively well for me. I hope you all are doing fine in
Henderson. I've forwarded your request on to Teresa Rodriguez who is
handling
your permit renewal. I understand your desire to coordinate your sampling
requirements and we'll address your request in the draft permit stage.
Thanks,
Dave

It's been a while since I've talked to you. I hope you are doing well. I
submitted a NPDES Permit (NC0020559) renewal application for the City of
Henderson's Nutbush Creek WWTP in October of 2001. The present permit
expires in April, 2002.
I have one requested change to the chronic toxicity monitoring schedule
which I hope is simple enough to have approved.
The present permit requires quarterly monitoring in March, June, September
and December. I would like to change the months for the quarterly
monitoring

RE: City of Henderson

Dear Mr. Goodrich,
NUTBUSH CREEK WASTEWATER
TREATMENT PLANT
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.

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.
w
(d) If Phase II is required, the City will secure financing 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.
(e) Since this Special Order is by Consent, neither party will file a petition for a
contested case or for judicial review concerning its terms.

3. The City agrees that unless excused under paragraph 4, the City will pay the Director of
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 $10,280 (single penalty).
effluent limits by September 30, 1999.
$5,140 (single penalty).
Failure to eliminate overflows from the
Redbud pump station by March 1.2002
Failure to monitor effluent toxicity $2000 per violation.
Failure to install replacement pump(s) as $1000 per violation. Does not apply if no
specified in 2 (j) overflow occurs.
Failure to submit progress reports $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;;
4

.4
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
permittee;
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.
5

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
autotherma
is heated in these digesters to a range of 110 degrees F to 130 degrees F by an
1 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 tar& 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.
