Dear Sir:
As per a letter received December 7, 2001 from Ken Schuster in the Raleigh Regional
Office regardins a notice of Violation and Assessment of a Civil Penalty. I am providing
this response.
A check in the amount of $45.27 is enclosed to cover the enforcement costs of the Civil
Penalty. The Durham County Attorney’s Office advised my office to submit the
remainder of the Civil Penalty to Durham County, to be forwarded to the local school
system, as per a recent court decision. We have submitted the application for this check
to be written.
The Durham County Industrial Pretreatment Program (IPP) has had some success in
determining the source(s) of Mercury discharges into our collection system. We are
evaluating this information to determine if additional IPP efforts may be necessary to
further reduce the discharges of Mercury and other regulated substances.
If you have any questions or need further information, please call me at 560-7992.
Sincerely,
Chuck Hill P.E

The Division of Water Quality assessed civil penalties in the amount of $2,045.27 and $2,295.27 against
Triangle WWTP in violations of G.S. 143-215.1(a)(6) and the subject permit, by discharging waste into
the waters of the State in violation of permit conditions. The assessments were sent via certified mail to
Triangle WWTP and were accompanied by a list of available options that included: payment of the
penalty, request for remission of the penalty, or request for an administrative hearing. If thirty (30) days
pass after the receipt of a civil penalty assessment and there has been no action to exercise one of the three
options cited above, then North Carolina General Statute 143-215.6A(g) allows the Secretary of the
Department of Environment and Natural Resources to request the Attorney General to institute a civil
action in Superior Court to recover the amount of the assessment. Records from our Division reveal that
the assessment documents were delivered on December 7, 2001 and January 18,2002 respectively. To
date, no response on behalf of the subject facility for the above enforcement cases have been received.
This letter serves final notice that the Division will proceed to refer your cases to the North Carolina
Attorney General’s Office for collection through the courts unless payment in the amounts of $2,045.27
and $2,295.27 is received by August 23, 2002.
Should you have any questions, please contact Vanessa Manuel at 919/733-5083, extension 532.

Other Special Items:
Our staff has reviewed our files of the above referenced site, as well as the plans and
specifications submitted, in order to make the following comments and recommendations for the
request.
The construction of the new phase I headworks and UV disinfection has started as allowed
by ATC no. 026051 ACT dated 3/23/01. The treatment train top of wall elevations are shown above
the 100 year elevation of 251.7 (251.75 was shown on one detail), as well as the chemical
containment walls. I did not see elevations for the electrical equipment panels, etc. These need to
be well above the 100 year flood elevation also.
With three BNR treatment trains, 4 clarifiers, and 5 tertiary sand filter cells reliability as per
2H.0124 is met. There are 3 each RAS/WAS pumps. The chemical feed systems have multiple
pumps for the various trains and meet reliability requirements. Three emergency generators for 100%
are included. A 500KW generator for headworks, administration building, and analytical laboratory.
A 1400KW generator for BNR process, clarifiers, and the RAS/WAS pumping system. A 500KW
The Raleigh Regional Office has reviewed the current submittal package requesting
Authorization to Construct (ATC) for the Phase II expansion. This expansion will include:
1. Five stage biological treatment Kruger A2O process utilizing an anaerobic “selector”,
primary anoxic tank, aerobic reactor (oxidation ditch), secondary anoxic reactor, and re­
aeration tank to remove organics and nutrients.
2. Alum (or sodium aluminate) is added to the mixed liquor prior to distribution chamber to
four 110' dia. x 16' SWD center-feed clarifiers. These clarifiers will maintain a minimum 15"
blanket at all times to create anoxic conditions and improved colloidal solids capture, prior
to recycling sludge back to the first BNR tank.
3. Replace the existing tertiary filtration with new five-celled traveling bridge type tertiary
sand filtration. A traveling backwash hood will be used for cleaning. The hood is indexed
to stop on each cell, lowered for a seal, and a backwash pump draws filter effluent from the
underlying effluent plenum. Backwash cycles will be able to be initiated either manually,
by timer , or via liquid level sensors.

generator for tertiary filtration, UV disinfection, post aeration, maintenance building, and chemical
feed systems.
The DWQ issued speculative limits on July 7, 2000 and they are shown on Table VI-2 in the
calculation manual. The entry in the table for the design year TN show “8371 Ibs/d”. The related
footnote does show it correctly: At 12 MGD 8,371 lb TN/month corresponds to an average
concentration of 2.75 mg/1.
The plant chemical feed capabilities will be; methanol introduced to the 2nd and 4th BNR
stages, potassium hydroxide feed in the oxidation ditches to maintain alkalinity, sodium aluminate
for phosphorous removal with capability to feed to the clarifier distribution box or the filters,
polymer for settling added to the clarifiers, and sodium hypochlorite to control biological growth in
the filters.
The SCADA is defined in volume 2 of the technical specifications.
An inspection of the present treatment plant was made on April 1, 2002 by Kirk Stafford of
this office. During the inspection it was noted that no staff gauge was present in either of the sludge
lagoons. Mr Cozart, the ORC stated that the staff gages were knocked down during sludge removal
in 2000 by the contractor and that the contractor was supposed to reinstall the gages. The West
lagoon had approximately 12 inches of freeboard and the East lagoon had approximately 18 inches
of freeboard. The RRO would like to ensure that those gages are replaced as soon as possible.
The RRO is concerned that phase II will not include residuals handling and that the phase
III residuals management construction is not planned to start until March of 2005. The ORC has
stated that during Phase I of the plant upgrade, the West lagoon sludge is scheduled to be land
applied. It is not clear what will be done with the sludge in the East Lagoon.
The regions previous comments from the EAA review include:
The RRO is concerned that the solids handling process is not adequately addressed in the EAA.
Although there is some mention to digesters and thickeners, there do not appear to be any shown
on the map of the final recommended alternative. The final recommended alternative shows one
sludge lagoon is to remain operational at least until start-up of new facility, however, there do not
appear to be any other sludge storage facilities identified. The RRO recommends that both sludge
storage lagoons be taken out of service once the new facility is on-line, and that appropriate new
storage tanks, digesters, and any other necessary solids handling equipment he included with Phase
II of construction. (This may already be the case, but it did not appear clear in the EAA.)
The City should address whether the lagoons are storage lagoons or treatment lagoons and
how they are complying with the 503 requirements
Based on the above, the RRO recommends that the subject project be awarded an ATC as
requested, pending P&E satisfaction of all requirements. The RRO would also appreciate
correspondence back pertaining to any request for additional information.

A detailed Engineering Alternative Analysis and Basis for Final Design Report was completed
for the Durham County Triangle Wastewater Treatment Facility in July 2000. Based on
recommendations from that Study and the subsequent Environmental Assessment, Durham
County has elected to upgrade the Triangle Wastewater Treatment Facility Upgrade to a
state-of-the-art, 12.0 MGD, five stage biological nutrient removal system (BNR) with chemical
phosphorus precipitation, tertiary sand filtration and UV disinfection. The proposed
improvements will allow Durham County to reduce total nitrogen mass discharges to
Northeast Creek by 69% from currently permitted levels and to reduce phosphorus mass
discharges by 50% from currently permitted levels.
In order to insure that the Triangle WWTF continues to produce an effluent in full compliance with
existing and future NPDES permit limits, construction of the proposed improvements must be
completed in Phases. This will allow existing treatment processes to remain in full operation until
completion of the five-stage BNR process. The proposed improvements will be constructed in
three phases via three separate construction contracts. Key treatment process
components included in each phase are as follows:

The Phase III improvements (Biosolids Management Processes) cannot be initiated until after
the new five-stage BNR process is completed. This is because the new biosolids
improvements will be constructed in the footprint of the existing aeration basins and,
therefore, cannot be taken off-line until after BNR startup. As such, this Interim Biosolids
Management Plan has been developed to insure the Triangle WWTF will continue to
adequately store, treat and dispose of all residuals produced while the facility is under the
various phases of construction.
The Triangle Wastewater Treatment Facility (WWTF) is located at the intersection of NC 55
and Alexander Drive in the southeast corner of Durham County, North Carolina. The
municipal wastewater treatment facility is owned by Durham County and is currently
operated under contract with Woodard & Curran Inc.

In 1993 the County completed a biosolids treatment and disposal plan and received State
Certification for periodic Class B land application onto 452 acres of agricultural lands in
Granville County. The County entered into two, 1-year contracts with EWR, Inc. and
BioGrow, Inc. for biosolids removal and disposal in 1993 and 1994. In 1995, AMSCO, Inc.,
now known as Synagro Southeast, Inc., was retained by the County under a 3-year contract
to remove and land-apply accumulated biosolids.
Upgrade to construct a new activated sludge secondary treatment
system with design capacity of 3 MGD.
Upgrade to expand existing activated sludge process to 6 MGD and
to construct two new tertiary sand filters to enhance BOD and TSS
removals.
In March 1998, Woodard and Curran, Inc. (W&C) was retained as the Contract Operator for
the Triangle WWTF and has been responsible for biosolids handling and disposal since that
time. W&C’s current contract with the County expires in 2003.
The Wastewater Treatment Facility (WWTF) was originally constructed in the earlyl960’s to
abate surface water pollution. The original facility consisted of a two-celled facultative
lagoon designed to reduce organic and suspended solids loading to Northeast Creek.
Since that time, three significant Wastewater Treatment Facility upgrades have been
completed including:
the National Pollution Discharge Elimination System (NPDES) subject to effluent conditions
described in Permit # NC0026051 which became effective on April 1, 1996.
The County converted the original, facultative lagoons into facultative sludge
stabilization/storage basins as part of the 1973 and 1990 upgrades. The use of these 8 MG
(16 MG total capacity) facultative, sludge storage lagoons has continued since that time.

^MCKEWCREED
Under W&C's management, biosolids are typically removed from the lagoons and land­
spread only once per year during a 30 - 60 day period coinciding with the farmer's hay
cropping schedule. In the past, W&C has retained the services of specialty firms to vacuum
dredge the lagoons and either land apply liquid biosolids or dewater the biosolids on-site
and dispose of dewatered cake on certified land-application sites located in Granville
County. Liquid biosolids removed from the lagoons typically have an average solids
content of 6 to 8 percent solids and have been as high as 14 percent solids.
In June 1999, the County retained McKim & Creed to assist them in completing the required
Engineering Alternative Analysis and Basis of Design Report prior to proceeding with
During the three year period from 1999-2001, Woodard & Curran has documented biosolids
production to be 2,587 dry tons. During this same period, they have either physically
removed, or documented volatile solids reduction in the lagoons amounting to a total of
4,649 dry tons.
A Facility Evaluation and Preliminary Engineering Study completed in 1997 identified a
number of recommended improvements and the need to expand the hydraulic and
organic capacity of the Triangle WWTF. The Evaluation also identified the need to replace
the existing biosolids facultative lagoons with more modern biosolids handling facilities to
insure the County can consistently satisfy biosolids disposal regulatory requirements.
According to Annual Operating Reports submitted to the County by W&C, the 1999 average
daily flow to the Triangle WWTF was 4.141 MGD. Waste activated sludge (WAS) production
during this same period was 1,112 dry tons. Then in 2000, biosolids production dropped to
753 dry tons and futher dropped to 722 DT in 2001. W&C attributes the significant
difference in WAS production in the second and third year to supplemental residuals
management by the biotechnology firm Ennix Bio-Service. According to W&C, the cultured
biomass additive has been successful in reducing soluble BODs concentrations in the lagoon
supernatant, which is regularly returned to the treatment process. This reduction in BODs
loading to the main treatment process has significantly decreased biosolids production and,
as a result, reduced the volume of biosolids wasted to the lagoons.
BIOSOLIDS PRODUCTION ESTIMATES

^MCKIM<9CREED
mandatory facility improvements and expanding the hydraulic and organic capacity of the
Triangle WWTF to accommodate projected sewage flows through the year 2023.
Estimates of biosolids production have been made on an annual basis for the period
between May 2002 and December 2006. This period fully includes all phases of
construction. Biosolids production estimates were developed using current Average
Daily Flow and actual biosolids production information provided by the Contract
Operator Woodard and Curran. Future year wastewater flows were previously
projected as reported in the Engineering Alternative Analysis and Basis for Design Report
dated July 2000, last updated October 2000. Assuming organic and suspended solids
concentrations remain consistent, biosolids production will be proportional to influent
flow to the plant. As such, residuals production on a dry weight basis are expected to
increase as summarized in Table 1.
This Interim Biosolids Management Plan is intended to provide overall guidance for
managing residuals produced during the four-year phased construction period prior to the
start-up of the new Biosolids Management Improvements.
Based on the final recommendations from the Engineering Alternative Analysis and Basis of
Design Report, the County has proceeded with permitting and design of a new, state-of-the-
art, 5-stage biological nutrient removal process at the existing Triangle WWTF site. In order to
expedite the environmental review and permitting process, the Engineering Alternative
Analysis concentrated on the main process train and did not evaluate biosolids
management alternatives in connection with the new facility.
Amendment #1 to the original Engineering Alternative Analysis has been completed in draft
form and specifically addresses permanent Biosolids Management at the upgraded Triangle
WWTF. It also provides recommendations and a basis for final design for the proposed new
biosolids storage, thickening, dewatering and stabilization processes.

As indicated in Table 2, biosolids production is projected to increase, yet biosolids
storage capacity will be temporarily reduced by 50% of current capacity during
construction. Construction of the new five-stage Biological Nutrient Removal process will
necessarily require permanent conversion of existing facultative lagoon cell #1 (western
lagoon). Thus, the County will be forced to operate with only one of the two 8 MG
facultative sludge storage/stabilization lagoons during the interim four-year construction
period.
The interim period during construction of the proposed wastewater system improvements
will be one of near continuous change. As such, the facilities available for biosolids
storage and stabilization are summarized in Table 2 by Phase and year.

Durham County currently has a total of 452.8 acres of permitted agricultural land
available for disposal of biosolids. Therefore, the County does not anticipate the need to
locate supplemental disposal sites. However, the County is prepared to use
supplemental disposal sites as necessary.
Per the latest NCDENR Non-Discharge Permit (#WQ 0007989), the 5-year adjusted land
application rate for Durham residuals (on agricultural land via surface application) is 7.66 Dry
Tons/acre. Durham will therefore need 280 acres of land for disposal of the entire 2,145 Dry
Tons as calculated below:
Years 2003 - 2004
Biosolids produced in years 2003 - 2004 in the existing extended aeration process and in
years 2005-2006 in the new five-stage BNR process will be discharged to Lagoon Cell #2
INTERIM BIOSOLIDS MANAGEMENT PLAN
Year 2002
In 2002, Durham County is arranging to retain a contract-dewatering firm to completely
remove, dewater and dispose of all existing biosolids in both facultative sludge storage
lagoons. The County has programmed sufficient funds to allow them to dispose of up to
3,500 dry tons of Class B residuals from the two lagoons in 2002.
The stored biosolids have already been tested to confirm that the material meets Class B
requirements for pathogen reduction (i.e. fecal coliform concentration <2,000,000 MPN per
one gram sample) and vector attraction (i.e. volatile solids reduction of >38%). It is
estimated that there are a total of 1872 dry tons of sludge in inventory (390 dry tons in
Lagoon Cell # 1 and an additional 1482 dry tons in Lagoon Cell #2). Between now and the
date that contract dewatering is scheduled for completion, an additional 270 dry tons of
waste biosolids will be generated and discharged to Lagoon Cell #2. Current estimates
indicate that there will be an estimated total of 2,145 dry tons to be removed in 2002. This is
well within the County's established budget.
YEAR
9
^MCKIM&CREED
In 2006, the County will have the option of either contract dewatering Lagoon Cell #2, as
planned for prioryears, or pumping the residuals into the new Class A biosolids
stabilization process. In either case, the County will have adequate resources to
accommodate storage and disposal of residuals for the entire interim period.
Per Table 2, Durham County will maintain biosolids stabilization/storage capacity for up
to 2,046 DT of biosolids at an average solids concentration of 7%. This is equivalent to 2.5
years storage capacity (based on 2002 production volumes) or 1.7 years storage
capacity (at anticipated 2006 biosolids production volumes). Therefore, even though
the County plans to remove biosolids annually at the same rate of production, they have
the ability to store biosolids on-site for up to 20- 24 months if necessary.
The projected biosolids production and the associated annual removal requirements
during these years are summarized in Table 3.

the proposed new 5-stage BNR process at the Triangle Wastewater Treatment Facility.
We trust that this document adequately addresses provisions for interim biosolids
management at the facility and will allow you to issue the Authorization to Construct for
the Phase II improvements.
On behalf of Durham County, we appreciate your assistance in expediting the ATC
review so that construction can proceed in accordance with the Construction
Schedule approved in the NPDES permit.

As we have discussed previously, Durham County will need to take one of the two
existing 8 MG facultative sludge storage lagoons off-line in early 2003 to accommodate
construction of the new facilities. Since the permanent, new biosolids management
processes will not be completed until 2006, we have prepared this interim plan to
provide detailed guidance as to how the Triangle WWTF will manage biosolids residuals
produced during the phased construction period.

The Division of Water Quality assessed civil penalties in the amount of $2,045.27 and $2,295.27 against
Triangle WWTP in violations of G.S. 143-215.1(a)(6) and the subject permit, by discharging waste into
the waters of the State in violation of permit conditions. The assessments were sent via certified mail to
Triangle WWTP and were accompanied by a list of available options that included: payment of the
penalty, request for remission of the penalty, or request for an administrative hearing. If thirty (30) days
pass after the receipt of a civil penalty assessment and there has been no action to exercise one of the three
options cited above, then North Carolina General Statute 143-215.6A(g) allows the Secretary of the
Department of Environment and Natural Resources to request the Attorney General to institute a civil
action in Superior Court to recover the amount of the assessment. Records from our Division reveal that
the assessment documents were delivered on December 7, 2001 and January 18, 2002 respectively. To
date, no response on behalf of the subject facility for the above enforcement cases have been received.

Dear Ms. Garrett:
This letter is to notify your office that the # 1 Automatic Barscreen in the south channel at the
Influent Pump Station for Durham County’s Triangle WWTP Permit # NC0026051has been
removed from service. The motor has failed and the gearbox is worn out. The # 2 barscreen in
the north channel is operable and currently in service.
This pump station is scheduled to be removed from service within nine months upon completion
of the new influent station currently under construction. We are planning to install a manually
cleaned barscreen to allow the temporary use of the south channel in the event the # 2 barscreen
in the north channel experiences operational problems. There is also a by-pass channel that
allows sewage into the pump well in the event the barscreens are plugged. This high level
bypass prevents overflows.
Please note this matter in your files. We will inform you when the manual barscreen is installed.
If you have any questions, contact me at [phone].

enforcement costs of each of these cases, and we sent a follow up letter regarding LV 01-
473 dated January 11, 2002. The Durham County Attorney’s Office also discussed these
cases with the Attorney General’s Office. A copy of a letter from our Assistant County

As you no doubt recall, in those matters Durham County had remitted to DENR the
administrative portion of the penalty assessed and then paid the rest directly to the school board.
Durham County believed, and still believes that this was correct in accordance with the provisions
of our State’s Constitution, Article IX, Section 7, and the decision of the Court in North Carolina
School Boards Association, et al. v. Richard H. Moore, et. al., 98 CVS 14158. Durham County
informed DENR of that action by correspondence hand delivered to DENR on January 7, 2002,
and February 18, 2002, (copies enclosed) which both included checks for the remitted
administrative costs and showed the budget action paying the balance to the school board.
Subsequently you contacted our office on behalf of DENR, conveying their disagreement
with the County’s legal position. After reviewing the matter, including the cun-ent posture of the
NC School Boards case, a case in which our school board is a plaintiff, I, on behalf of Durham
County, agreed to your proposal that, pending the issuance of a final appellate decision, Durham
County would pay any ftiture assessed penalties which it did not contest to DENR, not the school
board. It was also my understanding that part of your proposal was that no action would be
initiated by the State to collect that portion of the penalties already been paid to the school board.

Based upon the above facts, I conclude as a matter of law that Durham Triangle WWTP
violated the terms, conditions or requirements of NPDES Permit NC0026051 and N.C.G.S. 143-
215.1(a)(6) in the manner and extent shown in Attachment A. A civil penalty may be assessed in
accordance with the maximums established by N.C.G.S. 143-215.6A(a)(2).
The cover letter attached to the January 2002 DMR states that Cyanide violations are due
to Nitrite/Nitrate interference. Mr. Link Thrower, Lab Supervisor for Chemical & Environmental
Technology, Durham’s contract laboratory which conducted the Cyanide tests stated that his
company did not send a statement attributing Nitrite/Nitrate interference as the cause of the
violations. Mr. Thrower further stated that as a Standard Operating Procedure, the lab utilizes
Sulfamic Acid to eliminate the interference as per Standard Methods 18th Edition.

Dear Mr. Schuster:
5.
This letter is to propose a procedure for closing the west sludge lagoon at the Durham
County - Triangle Wastewater Treatment Facility. We are unaware of any regulatory
requirements for non-hazardous sludge lagoon closures and are providing this proposal
per your request to Durham County. This lagoon is scheduled for closure by the end of
2002 to allow construction of Phase 2 for the new treatment system in the current
location of the west sludge lagoon. Removal of 3500 dry tons of sludge from the facility
began in September. This portion of the project is scheduled for completion within
ninety days of the start date of sludge removal. The dried sludge removed will be
disposed at landfills in Rougemont, NC and Lawrenceville, VA. The final closure of this
lagoon must be completed as soon as possible to allow construction of the Phase 2
treatment modifications to begin by January 2003.
Woodard & Curran Inc. as facility operations contractor will assist Durham County
Utilities in oversight of the sludge removal and closure. No hazardous wastes have been
disposed into this sludge lagoon. It only received sludge from the wastewater treatment
facility. The contents have been analyzed for TCLP and no contamination of concern
was detected. The previous groundwater monitoring wells analyses collected during the
1990’s have also been reviewed and no contamination was detected. The groundwater
monitoring was discontinued in 2000 because no contamination from the lagoon had been
indicated.

The proposed closure plan includes:
Remove all sludge from the west lagoon.
Pump remaining water into the east lagoon or to the plant head waters as
allowable by influent parameters.
Apply limestone to the surface.
Sample the surface at six inch depth for TCLP and total nitrogen parameters. The
sample to be analyzed shall be a composite of samples collected in a grid pattern
of eight distinct locations across the surface of the lagoon bottom.
After the analyses confirm that there is no threat of environmental contamination
from the west lagoon, the closure will be complete.

Please contact me if you have any further questions or additional suggestions regarding

County Utilities Department will prepare the information you need to finalize approval of
this plan.
Your timely review of this proposed closure plan is appreciated. I look forward to
discussing this closure with you and your staff. Durham County is interested in
completing this closure as rapidly as possible to insure a timely initiation of construction
of their Phase 2 construction.

Attachment
Attached is a letter from Jerry Rimmer regarding a lagoon closure request at the Durham
County Triangle WWTF. Please recall that the draft Groundwater policy includes
guidance on the sampling that should be performed and the limitations that must be met.
If Groundwater finds that it is ok to leave any sludge in place, Water Quality will agree if
the lagoon is going to be back filled and graded to shed water. If the lagoon is to remain
open. Water Quality requires that the sludge be removed regardless of the analytical
results. Kirk, please coordinate the appropriate response(s) and pass back through me.

Dear Mr. Allison:
On October 25, 2002, Mr. Kirk Stafford of the Raleigh Regional Office of the Division of
Water Quality (DWQ) conducted a Compliance Evaluation Inspection (CEI) of the Bible Baptist
Church WWTP accompanied by Mr. Gary MacConnell of MacConnell & Associates who was
contracted by the church for design of the subject facility. Mr. MacConnell’s assistance and
cooperation was helpful and appreciated. As a result of the inspection, the following items were
noted.

2) The facility was last issued NPDES Permit NC0058785 effective September 1, 1994. Due to
the nature of the facility’s wastewater discharge, there was a permit change to General Permit
NCG551111 which became effective June 15, 2001. This permit was reissued and became
effective August 1, 2002 and will expire July 31, 2007. Please read and make yourself aware of
all the permit conditions including annual effluent monitoring requirement and retain those
records for five years and have those records readily available for inspection.
3) Bible Baptist Church applied for coverage under SOC 99-007 on February 15, 1999 due to
permit violations dating from May 1998. The church decided to construct a wastewater
forcemain to the City of Durham’s collection system but was rejected for road easement access

1) The subject facility was constructed under an Authorization to Construct (ATC) issued by the
Division on June 15, 2001. The wastewater treatment plant (WWTP) consists of a 2,000 gallon
septic tank, a 3,000 gallon dosing/flow equalization tank (recirculation pump tank), above
ground 14 feet X 16 feet recirculating sandfilter with eight lateral dosing lines, tablet chlorinator,
chlorine contact tank, and cascade aeration with discharge to an unnamed tributary to Ellerbe
Creek.

7) Proper maintenance of the subject wastewater treatment plant is crucial to the operation and
longevity of the components of the system. Please note the items on the effluent limitations and
monitoring requirements page referring to maintenance and the documentation requirements.
5) The system was not discharging at the time of inspection but clear effluent was noted in the
chlorine contact chamber.

by the North Carolina Dept. Of Transportation (DOT). The church then requested that Durham
County obtain right-of-way easement from the DOT which would then make Durham County
responsible for the sewer line should the church not act responsibly. Durham County refused to
take responsibility for the sewer line as per a letter from the church dated March 8, 2000. At this
point the Director of DWQ contacted the DOT and was not successful obtaining the easement for
the church. In May 2001 the church decided to construct a new recirculating sandfilter system
with disinfection. It is noted that permit violations ceased after issuance of Permit NCG551111
on June 15, 2001 and therefore no SOC could be entered into. The sandfilter systenTs Final
Engineer’s Certification of Completion was stamped August 23, 2002. Please send a written
response to this office within 10 working days of receipt of this correspondence stating
specifically why the sandfilter system took over one year to install after the ATC was issued on
June 15,2001.
6) Chlorine tablets were present in the chlorinator. Please ensure that sufficient chlorine is
maintained in the chlorinator at all times to prevent violation of the fecal Coliform Monthly
Average and Daily Maximum limits specified in the subject permit.
4) Bible Baptist Church was assessed eleven times for NPDES Permit NC0058785 violations
from Augustus, 1998 through November 22, 2000 totaling $12,689.55 which included dines and
costs. These assessments were to be addressed in the SOC through an up-front penalty and the
church was made aware of this. Since an SOC could not be entered into, these assessments were
outstanding but closed by the Division’s Point Source Compliance/Enforcement Unit on
December 10, 2001.

The Division received the correspondence dated October 7, 2002 from Jerry Rimmer of
Woodard & Curran detailing closure procedures of the subject lagoon. The following is the
cunent draft policy detailing the required Groundwater Section (Section) procedures for lagoon
closure:
2) The following analytical procedures should be run on the sludge samples:
a) Toxicity Characteristic Leaching Procedure (TCLP) SW-846
EPA Method 1211 for volitiles, semi-volitiles, and metals.
3) If the lagoon does not have a liner, then the underlying material should be sampled in three
locations also and analyzed for the TCLP procedures in (2)(a). If the lagoon has a natural

As you have noted, the Groundwater Section requires an initial in-place sampling of the
sludge at three locations within the lagoon. The Rimmer letter implies that the sludge has already
been analyzed by TCLP methods, with “no contamination of concern” detected. The section
requires a written, sealed (by P.E. or P.G.) sampling report presenting and summarizing this data,
with an appropriately sealed map showing the locations and pertinent lagoon and facility
features. Please submit the report before transportation of the sludge to a landfill so that the
Section may evaluate the suggested non-hazardous waste characterization.
The proposed substrate sampling plan differs from the Section requirements in both the
number and sampling locations, three and eight respectively, and the practice of compositing the
sample. The Section views compositing as not effective in locating specific contaminant
7) The final approval of the above procedure and analysis is granted by the Raleigh Regional
Office groundwater Supervisor Mr. Jay Zimmerman.
4) If the sludge/clay/soil liner underlying soil material has TCLP concentrations that are above
the TCLP regulatory limits, then the material is considered hazardous, and the Division of Waste
Management/Hazardous Waste Section should be contacted, and the material does need to be
excavated.

b) Perform predictive calculations that demonstrate that the verticle leaching of the
contaminant in question in the material will not cause an accedence of Groundwater 2L
Standards in the underlying surficial groundwater saturation zone. This calculation would
probably require the need of site characterization of the subsurface hydrogeologic
parameters of concern. The predictive calculation would need to consider vertical
leaching and subsequent mixing of the groundwater saturation zone.
6) If the sludge/clay/soil liner underlying soil material has TCLP concentrations that are below
the TCLP regulatory limits AND above Groundwater 2L Standards, then there are two options:
a) Excavate the material that is above Groundwater 2L Standards, then proceed with
lagoon closure.
5) If the sludge/clay/soil liner underlying soil material has TCLP concentrations that are below
the TCLP regulatory limits AND below Groundwater 2L Standards, then the sludge may be left
in place and the lagoon closed without excavating the sludge.
compacted clay liner, then the clay liner should be sampled in three locations and analyzed for
TCLP procedures in (2)(a). If the lagoon has a synthetic liner, then the soil material should be
sampled in three locations and analyzed for TCLP procedures in (2)(a). From a field sampling
point of view, the sludge and underlying clay or underlying soil material can be collected using a
core barrel sampler for shallow soils, where the core barrel is driven into the sludge/clay/soil
matrix and later extracted.

policy without convincing scientific arguments that characterization and remediation would be
aided. Please adhere to Section policy unless otherwise noted.

West Lagoon Closure @ Triangle Wastewater Treatment Plant
NPDES Permit No. NC 0026051-Durham County
This letter is to acknowledge receipt of approval for the closure of the West Lagoon at the T"angle
Wastewater Treatment Facility in your letter to Chuck Hill dated November 12, 2002. Thank y
for your response to the County’s request on this issue.
I would like to make one clarification I have talked to Jay Zimmerman about the actual sludge
testing and the submittal of these tests to him. Mr. Zimmerman confirmed that since the sludge will
be removed prior to the lagoon closure, the testing related to the sludge itself is not required for the
lagoon closure.
Therefore, please note that we will close the lagoon per the procedure outlined in your responsei to
Chuck Hill dated November 12, 2002, except for the testing of the sludge, which will already be
removed. The certified test results for the clay liner will be transmitted to Mr. Zimmerman for fina
approval of the closure.
Please contact me at 919-544-8280 if you have any further questions or comments.

This is to notify NCDENR that the effluent pump and disinfection portion of Phase 1
Modification Project is complete for Durham County - Triangle Wastewater Treatment
Facility. Woodard & Curran as operator of the facility will utilize the effluent pumping
station, UV Disinfection and Post Aeration Systems beginning immediately. Contractors
continue to troubleshoot and make necessary adjustments to the systems to insure proper
operation of all systems to insure continued compliance with permit parameters. We are
using UV disinfection at this time and not utilizing chlorine.

The discharge will be over a weir installed above the 100 year flood level to eliminate
contamination from creek water flooding into the system as before. The sampling
location will be at the discharge weir after treatment, clarification, filtration, disinfection
and post aeration. The fecal coliform and other grab samples location is planned for the
same location as the effluent is discharged from the final treatment portion of the facility.
