Subject: NPDES Final Permit
Wilson - Hominy Creek WWMF
Permit No. NC0023906
Wilson County
Dear Mr. Brice:
In accordance with the application for discharge permit, the Division is forwarding
herewith the subject NPDES permit for the City of Wilson, Hominy Creek Wastewater Management
Facility (WWMF), NPDES No. NC0023906. 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.
The Division of Water Quality (the Division) received your comments, dated August 27,
2003, on the draft permit. Based on these comments, the following changes have been made from
the draft permit:
• The typographical errors have been corrected (Items 1., 2., and 4. of your letter).
• The Division recently changed some items in the boiler plate (standard) language of individual
NPDES permits. This included the postmark date of the DMRs (modified from the 30th day
following the reporting period to the 28th day of the reporting period). This was modified
because February, excluding leap years, only has 28 days.
• Some minor changes have been made to the permit based on EPA Region IV comments
(specifying "total" metals and "total suspended solids") .
• As explained in Item 3 of your comment letter, the Division is aware of some of the delays with
final approval of the BNR addition. Based on your comments, the Division has agreed to allow
the City of Wilson until November 1, 2004 to meet the more stringent ammonia requirements.
The Division is limited in how much time may be offered to comply with this requirement,
since a schedule of compliance was placed in the previous permit.
Other than those changes listed above, no major changes have been made to this final permit
from the draft permit dated July 30, 2003.
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, Mail Service Center 6714, Raleigh, North Carolina
27699-6714. Unless such a demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division of
Water Quality. The Division of Water Quality may require modification or revocation and
reissuance of the permit.

A.(2.) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (lb/mo) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/L) of the
composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the
December report for that year.
A.(3.) ANNUAL LIMITS FOR TOTAL NITROGEN
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River
basin are annual limits and are applied for .the calendar year.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load
limit in. this Permit if:
i. the Permittee's annual TN Load is less than or equal to said limit, or
ii. the Permittee is a Co-Permittee Member of a compliance association.
c. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes
in the Permittee's TN allocation.
i. Allowable changes . include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by the
Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application, the
Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
iv. Application shall be sent to:

d. If the Permittee is a member and co-permittee of an approved compliance association, its TN
discharge during that year is governed by that association's group NPDES permit and the TN
limits therein.
i. The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
ii. Association roster(s) and members' TN allocations will be updated annually and in
accordance with state and federal program requirements.
iii. If the Permittee intends to join or leave a compliance association, the Division must be
notified of the proposed action in accordance with the procedures defined in the
association's NPDES permit.
(1) Upon receipt of timely and proper notification, the Division will modify the permit
as appropriate and in accordance with state and federal program requirements.
(2) Membership changes in a compliance association become effective on January 1
of the year following modification of the association's permit.
e. The TN monitoring and reporting requirements in this Permit remain in effect until
expiration of this Permit and are not affected by the Permittee's membership in a compliance
association.
A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
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, puarterly 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 February, May, August, and November. 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.
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. 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 the pass/fail results and THP3B for the Chronic Value. Additionally,
DWQ Form AT-3 (original) is to be sent to the following address:

A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) (cont'd.)
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.
A. (5.) Effective Date for More Stringent NH3-N Limits
The limits of 2 mg/1 (April 1- October 31) and 4 mg/1 (November 1 through March 31) shall be in
effect until November 1, 2004, at which time new limits of 1 mg/1 and 2 mg/1 shall become
effective.
A. (6.) Fecal Coliform Compliance Condition
Should the City of Wilson be deemed by the Division of Water Quality to be chronically
noncompliant with the weekly average and/or monthly average fecal coliform limit after
completion of the expansion to 14 MGD, the City shall submit plans and specifications within 90
days after notification by the Division. The plans and specifications shall provide for an
adequately designed chlorine disinfection facility. If another method of disinfection is proposed, it
should conform to conventional design parameters, as well as any minimum requirements
specified by the Division. Bidding and subsequent construction of the project shall commence
immediately after the issuance of the Authorization to Construct permit.

beginning of the more stringent NH3-N limit (July 1, 2004) that the City agreed to.
There have been delays in getting the plans and specifications approved for the solids
handling facilities project, which includes the addition of a BNR tank for NH3-N removal
efficiency. These delays are beyond the City's control. The Hominy Creek WWMF 201
Amendment was submitted in September 2002. The Amendment was submitted
demonstrating the need for a future flow expansion within the 20 year planning period.
This decision by the City and Hazen and Sawyer to include future flow expansion was
based on advice from DWQ staff. We received technical comments on the 201
Amendment on February 26, 2003. Environmental comments were received on April 11, )
2003. The majority of the environmental comments were based on DWQ's desire not to
approve a document discussing future flow expansion. We agreed to modify the

The FONSI was issued August 13, 2003. The design plans were ready for regulatory
review in December 2002, but we were told not to submit the plans until the FONSI had
been completed. Due to the significant delay in the process, we requested a parallel plan
review with completion of DWQ's review of the 201 Amendment and submitted the
plans on April 11, 2003. Review comments from Construction Grants and Loan have not
been received. Based on these significant delays, the City of Wilson request an extension
of six (6) months to the effective date of the more stringent NH3-N limit. The effective
date would become January 1, 2005. This request is based on being able to advertise the
project by the end of this year.
4. The fifth page, A. (1.) 8. indicates two outfalls 001 and 002. The City has only 1

Susan,
I don't really have a concern with this. However, if you extend the
compliance schedule, will the extension be outlined in the permit, or
will you have a reopener to address this? If it is not addressed in the
"redrafted" permit, a major modification will be required to change the
compliance date once the permit is issued.
I had issued a no comment letter on this draft permit dated September
16, 2003. If there are significant changes, other than this (which you
stated in your e-mail that there was only this issue and typos), please
send me a proposed final permit. Or, if this is the only change, could
you forward me an electronic copy of the changes that you make and I
will review quickly and send you an e-mail stating that I had reviewed
and aril : okay with changes.
Thanks and call me if you. have any. questions [phone].

Madolyn,
We gave the City of Wilson until July 1, 2004 to comply with NH3 limits
of 1 & 2 mg/1. They have had to go through our State Loan program and
there have been some delays with getting their funding for
improvements. With their comments on their draft permit - they
requested that they have until January 1, 2005 to meet the NH3 limits.
We plan to give them some time - but only until November 1, 2004 (this
will mean they will have had a schedule of 3 years to comply with the
NH3 limit - the previous permit was effective Nov. 1, 2001) . This will
be the only significant change from their draft permit (other than
several typographical errors). Let me know if you have comments.

Susan,
The following are my comments on the City of Wilson draft permit. Most
are considered "minor" comments, but please respond to me by September
9th so we can resolve any issues prior to the 30-day review deadline of
September 12, 2003.
Thanks,
Madolyn Dominy
1) The term "total suspended residue" should be changed to total
suspended solids in effluent limitations pages and footnotes.
O (c_
2) All metals, such as copper and zinc, should be expressed as "total" Q(L
or "total recoverable" on effluent limitations pages.
3) Detection limits for various organic pollutants in the expanded
effluent data section of the permit application are too high and not
sensitive enough. Methods 624/625 are expected to achieve much lower
detection limits. I have expressed this same comment to Mark McIntire
and Dave Goodrich as a significant concern of EPA Region 4.

I have reviewed the subject draft permit with the following comment. The changes to the
current draft permit are detailed in the cover letter. The RRO supports the changes. It is
noted that the Residual Chlorine limit is specified as 18 ug/l. It is my understanding that
Residual Chlorine limits in NPDES permits would either be 17 ug/1 or 28 ug/l. The RRO
does not have a concern if this is the actual limit. No errors or omissions were noticed
during the review.

SUMMARY
Wilson operates a 14 MGD wastewater treatment facility that discharges into Contentnea Creek
which is a tributary to the Neuse River. The City has modified the plant to achieve biological
nutrient removal (esp. for total nitrogen) which brought the ultimate plant capacity to 14 MGD.
The City is also in the process of completing a 201 plan for plant improvements to meet the
more stringent NH3-N limits which will be implemented July 2004.
Contentnea Creek is now listed as supporting near this area of the discharge. However,
instream data indicate depressed D.O.'s below the discharge (and this section is not considered
impaired, but is listed on 303(d) due to low D.O.$).
Contentnea Creek is a tributary to the Neuse River. According to the Basinwide Water Quality
Management Plan for the Neuse, the primary water quality considerations for point sources in
the basin are discharges of (1) oxygen -demanding substances and (2) nutrients.
As stated in the previous fact sheet (dated May 4, 2000), due to the swamp -like nature of
Contentnea Creek, a steady state one dimensional model could not be used. The BODS limits
for 14 MGD are based on BPJ (tertiary treatment.levels). The Wilson - Hominy Creek plant is
designed for tertiary treatment and biological nutrient removal.
Point source rules regarding control of TN and TP have been passed by the EMC. To address
the nutrient reduction issue, the City is a participant in the Neuse River Compliance
Association (this will allow the facility to comply with the nitrogen limit through the
Association).
Wilson/ Hominy Crcek WWMF
NPDES Renewal
Page 1

The Wilson - Hominy Creek WWMF has a full pretreatment program through the Division of
Water Quality's Pretreatment Unit. This program will continue to be implemented in
accordance with the permit.
The City also is reusing a portion of its wastewater (as per WQ0020915).
TOXICITY TESTING:
Current Requirement: Chronic P/F @ 90% (also recommended with renewal)
Wilson has had "passes" in 2002 and 2003. (The facility had a failure November and December
2001, but passes since that time. Wilson attributed this to a type of polymer they were trying
at the time.) Due to the consecutive passes for the past year, they are not subject to the Action
Level policy.
COMPLIANCE SUMMARY: BASED ON THE PREVIOUS 2 YEARS
The City adjudicated the previous permit over the more stringent NH3-N limit (1 mg/1 (sum)).
The adjudicatory settlement allowed Wilson a compliance schedule for the more stringent NH3-
N limit. The City has until July 2004 to comply with the limit.
The City has had some flow violations during the first quarter of this year (NC has had high
rainfall events all winter) - not high enough to trigger a civil penalty. Average flow for 2002 =
9.73 MGD (drought year); January 2003 - May 2003 = 13.52 MGD (high rainfall).
Per computer print-out, the facility appears to be in compliance with other limits.
Compliance Evaluation Inspection and staff report indicate that the facility is well maintained
and operated.
INSTREAM MONITORING:
Wilson is part of the Lower Neuse Basin Association (LNBA) and is not required to perform the
instream monitoring listed in this permit.
The LNBA monitors upstream and downstream sites on Contentnea Creek [J6764000,
upstream at Hwy. 301; J6890000, downstream at NCSR 1622; J7210000, downstream at Hwy.
58). Depressed DOs have occurred at the downstream sites, with a trend indicating a definite
impact from the upstream to the downstream sites. This creek is likely affected due to both
point and nonpoint source impacts; additionally, this is classified as "swamp", in which DOs
may be naturally depressed on occasion. A new federal program, the Unified Watershed
Assessment, will provide funds to study Contentnea Creek and possibly determine causative
factors.
TOXICANT PARAMETERS
A reasonable potential analysis (RPA) was conducted for all toxicants currently monitored [Ag,
Cd, Cu, Zn, Cr, Hg - through the permit; Ni, As, Se, Mo, Chlorides, Al, CN, Pb - through the
LTMP). The data evaluated was reported between from June 2001 - May 2003.
Where data were available, both the chronic and acute (1/2 FAV) were evaluated for reasonable
potential.

Copper and Zinc showed RP to exceed the action level standard. Monitoring will be continued
t a frequency of monthly.
Other parameters did not show RP (and Cr, Pb, Hg, Al, Ag, As, Se, Mo all had values below
detection for the 2 year period) .
PROPOSED CHANGES:
Nutrients
Wilson is a member of the Neuse nutrient compliance group. As a member of the compliance
association, the annual load limit for total nitrogen will not have to be met. The individual TN
load for Wilson - Hominy Creek is 157,684 lbs/year. The total phosphorus limit of 2 mg/1 was
instituted in the previous permit (and since Wilson is a member of the Compliance Association,
the 2 mg/1 TP limit is applied again in this permit).
Metals:
Copper and Zinc did demonstrate a reasonable potential to exceed the acute criteria. However,
these are both Action Level parameters and should be reviewed in conjunction with toxicity
testing. Monthly monitoring of these parameters will continue. [See above for more detailed
explanation - as well as RP analysis].
Other metals demonstrated no RP.
Data resulting from the LTMP showed values less than detect for most parameters except
molybdenum and chlorides. Chlorides are a concern in water supply - and this is not a water
supply classified water body (molybdenum is monitored through the LTMP - there is no WQ
standard for it). No changes are proposed in the permit based on LTMP data.
Other Parameters
Other than conventional parameters, the parameters sampled in the application had above
detection levels for copper, zinc, chloromethane. No changes are proposed based on
information in the permit application (the volatile compound was in amounts below WQ
standards).
Based on the NH3-N policy adopted October 15, 2003, weekly average NH3-N limits have been
inserted for the existing flow.
An annual priority pollutant scan has also been inserted in the permit to ensure that the
permittee complies with the requirement in the municipal permit applications.
The fecal coliform special condition is being continued with this renewal (based on
the modifications for the 14 MGD, the chlorine contact basin is not going to be
enlarged, so the NPDES Unit has the same concerns regarding the contact time).
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: July 30, 2003 (est.)
Permit Scheduled to Issue: September 16, 2003 (est.)

PART IV - EVALUATION AND RECOMMENDATIONS
The permit application has been reviewed and a site visit and CEI performed by RRO staff.
The application notes that in addition to standard domestic strength waste discharged to the
facility, parameters including metals, laundry waste, pharmaceuticals, commercial lab waste,
and hospital waste are discharged to the facility. The parameters and limits in the current
permit appear to be satisfactory for this facility.
The facility is well operated and maintained, and compliant with permit limits.
On another note, Wilson has talked with the Towns of Elm City and Bailey regarding possible
connection. Both of these towns have chronic compliance problems at their spray irrigation
plants.
The RRO recommends that the permit be reissued in accordance with the basinwide permitting
strategy.

That segment is currently Supporting based on benthic samples. The
downstream samples have improved from Fair to Good Fair between 1995 and
2000. The site immediately downstream of the discharge was Fair in 2000 but
was good -fair in a 2001 resample. There are still problems and the slight
increases are likely due to a lack of runoff because of the drought. The
low DO site was just below buckhorn dam and nobody seemed have any ideas on
that one. The LNBA sites in the watershed did not register DOs that were too
low. There are no stoneflies in Contentnea--indicating problems. Bottom
line is -- it is barely supporting.

Thats right. Apparently their draft limits and actual limits varied a
little. By the way, can you send me a write off on the chlorine thing?
They know the permit condition will remain in so that is fine in your
concurrence. RB

Susan,
We do not recommend adding limits for copper and zinc at this time. This facility had no further WET
violations after being kicked into the process. Indications are that a polymer was the source of their
toxicity, but they did not definitively rule out copper and zinc. Therefore, we don't recommend adding
limits for Cu and Zn, but the facility is still subject to the process if they have WET failures in the future
and still have RP to exceed the action level standards instream.
Call me if you have questions.
Matt

Subject: City of Wilson - 201 Facilities Plan (September, 2002)
NPDES No. NC0023906
Wilson County
I have briefly reviewed the 201 Plan submitted by Hazen & Sawyer on behalf of the City
of Wilson [September 2002, Revised May 20031.
It appears that the facility will not be expanding beyond 14 MGD (20 year projected
flow) and this document reflects only conditions for 14 MGD. The City is currently
permitted for 14 MGD, so the NPDES Unit has no further comments on this portion of
the 201.
The NPDES Unit still raises the concern regarding hydraulic retention time for chlorine
contact. Although the contact time is estimated as 45 minutes - it appears that the
"contact tanks" are used for chlorination, dechlorination, and post aeration. Once
again, we encourage the City to implement additional true chlorine contact time.
Likely, if this is not done, the language in Condition A. (6.) of the NPDES permit will be
continued with the next permit renewal (and future permit cycles).

NPDES Unit
Subject: City of Wilson - 201 Facilities Plan (September, 2002)
NPDES No. NC0023906
Wilson County
I have reviewed the 201 Plan submitted by Hazen & Sawyer on behalf of the City of
Wilson.
As stated in the document, the City of Wilson is required to meet more stringent
ammonia limits by July 1, 2004,.as agreed through the adjudicatory settlement and
subsequent permit issuance dated September 28, 2001.
The document primarily addresses how the City of Wilson will comply with the more
stringent ammonia limits at the current flow of 14 MGD. The NPDES Unit ,agrees that
upgrades to theplant are necessary to comply with the more stringent limits. In review
of the improvements for 14 MGD, the NPDES Unit also recommends that the chlorine
contact time be evaluated again to determine if adequate time is provided to
consistently meet the fecal coliform limit. This was a concern during the previous
review of the expansion; to.14:MGD and is the reason Condition A:(6.) was implemente6.
in the permit.
The NPDES Unit has not received a request from the City of Wilson for. speculative
limits for a flow of 18 MGD: An increase of permitted flow.from 14 MGD to 18 MGD
could have a major impacton the dissolved oxygen of Contentnea Creek. Due to the
swamp -like nature of Contentnea Creek, providing speculative limits will be difficult
and could be time -consumptive. Review of dissolved oxygen data during the last permit
renewal indicated that downstream dissolved oxygen levels were depressed, which may
also have an effect on the speculative limits. Additionally, Contentnea Creek, below the
Wilson water supply intake, is listed as biologically impaired (with impairment
historically listed as attributable to sediment).
Alternative analyses will have to be thoroughly documented prior to or upon any NPDES
application for expansion above 14 MGD. The NPDES Unit recommends that Wilson
thoroughly evaluate alternatives and re -use options prior to expansion of the treatment
plant. The NPDES Unit's Engineering Alternatives Analysis Guidance document is
available on the Division's website: [http://h2o.enr.state.nc.us/NPDES/
documents.html).
As stated in the 201 document, the City plans to implement the improvements to the
existing 14 MGD plant during Phase I of the project and then the ultimate 20 year
design flow expansion during Phase II of the project. As stated previously, the NPDES
Unit has no objections to the proposed modification and improvements for the 14 MGD
design flow. However, prior to expanding to 18 MGD or funding of Phase II (18 MGD),
the document should be revised to reflect speculative limits for 18 MGD, thoroughly
document alternatives and thoroughly justify the 20 year flow projcction.

Subject: Evaluation of Copper and Zinc per DWQ's Copper and Zinc Action Level Policy
December 10, 2002 Report
NPDES No. NC0023906
Wilson County
Dear Mr. Pittman:
r(bc
This office has completed a review of the subject document prepared by the City dated
December 10, 2002. DWQ's Copper and Zinc Action Level Policy was triggered by the
November and December 2001 toxicity test failures. An evaluation of reasonable potential to
violate instream action levelsTotal for these parameters was conducted by the NPDES Unit and
NOVs dated October 22, 2001, January 24, 2002 and March 11, 2002 were sent to the facility.
The City submitted correspondence dated April 2, 2002 to our Unit and chose Option 3
(Toxicity Identification Evaluation) to definitively rule out copper and/or zinc as causes of
effluent toxicity.
The City's December 10 report cites no additional effluent toxicity permit limit violations
since December 2001 after eliminating a WWTP polymer that was suspected of causing the
chronic toxicity effluent permit limit violations. The City declined to perform metal "spiking" of
non -toxic samples during the nine month period.
The City requests that the December 10 report be considered as the final report "for the
evaluation of the causes for the toxicity failures experienced during August, November and
December 2001." While our office considers that City's actions to address these WET limit
failures to be proactive and appreciated, we cannot accept the December 10 report as conclusive
evidence to rule out copper and zinc as causative effluent toxicants. It appears that the City's
investigative work regarding polymer usage had a positive effect in reducing effluent toxicity to
acceptable levels; however, evidence of instream concentrations for these parameters below the
action level standard does not "definitively" rule out these two metals.

RESIDUALS MANAGEMENT PLAN
HOMINY CREEK WASTEWATER MANAGEMENT FACILITY
Biosolids generated at the Hominy Creek facility are lime stab ilized prior to disposal by
land application. Two open digester tanks are used to stabilize biosolids that are applied
as a liquid. A process called Biofix is used to stabilize dewatered biosolids.
For the liquid process, lime is brought in by tanker and injected into the stabilization tank
while the tank is mixed. Once the biosolids are stabilized. 'he contents of the
stabilization tank are transferred to the other tank prior to disposal. Either tank can be
used for stabilization and/or storage. The Class B residual: arc: land applied in liquid
form to permitted sites.
A filter press is also used to dewater biosolids that are stabilized by lime during the
Biofix process. The cake, Class A or Class B can be produced, is applied on permitted
land or taken to an approved landfill if permitted land is not available.
Synagro Southeast, Inc operates the City of Wilson land application program. The
program requires full time operation, normally 5 to 6 days per week and 8 to 12 hours per
day.

HOMINY CREEK WATER RECLAMATION FACILITY
INTRODUCTION AND OVERVIEW
A. GENERAL
The Hominy Creek Water Reclamation Facility (WRF) provides tertiary treatment, including
nitrogen and phosphorus removal, for a design capacity of 14 mgd. Raw wastewater from
the off -site and on -site pump stations receives preliminary treatment by screening and grit
removal before being conveyed to preaeration tanks. From the preaeration tanks, flow is
distributed to primary clarifiers and then to a biological nutrient removal (BNR) activated
sludge stage. Major process units of the BNR activated sludge stage consist of a biological
phosphorus removal (BPR) tank, aeration tanks, secondary clarifiers and return activated
sludge (RAS) pumping stations. Secondary clarifier effluent receives tertiary treatment in
effluent filters and is then aerated and disinfected in post aeration/chlorine contact tanks to
meet DO and fecal coliform effluent limits. The effluent is then dechlorinated at the end of
the post aeration/chlorine contact tanks to meet a total residual chlorine effluent limit, and
is discharged to Contentnea Creek through a 48-inch effluent outfall.
The solids handling facilities for the primary solids and waste activated sludge consist of a
gravity belt thickener for waste activated sludge thickening and anaerobic digesters/solids
storage tanks for solids stabilization and storage, followed by liquid biosolids land
application on privately -owned farm land. One of the anaerobic digesters/solids storage
tanks can also be used for liquid lime stabilization prior to land application. Sand drying
beds are available for standby dewatering or for use when draining a digester for cleaning.
