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 schedule for construction is os 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.

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.
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-yeor 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.
the National Pollution Discharge Elimination System (NPDES) subject to effluent conditions
described in Permit # NC0026051 which become effective on April 1, 1996.
Upgrade to expand existing activated sludge process to 6 MGD and
to construct two new tertiary sand filters to enhance BOD and TSS
removals.
Upgrade to construct a new activated sludge secondary treatment
system with design capacity of 3 MGD.
The Wastewater Treatment Facility (WWTF) was originally constructed in the earlyl 960'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 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.

^MCKIM<&CREED
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
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.
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&CREED
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-stoge biological nutrient removal process at the existing Triangle WWTF site. In orderto
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.
mandatory facility improvements and expanding the hydraulic and organic capacity of the
Triangle WWTF to accommodate projected sewage flows through the year 2023.
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.
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.

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.

(MGD)
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.

MCKIM&CREED
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
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.
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 bean estimated total of 2,145 dry tons to be removed in 2002. This is
well within the County’s established budget.
YEAR
9
^MCfOM&CREED
In 2006, the County will hove the option of either contract dewatering Lagoon Cell #2, as
planned for prior years, 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.
(eastern lagoon). The Contract Operators will continue to gravity thicken and decant
liquid on a semi-continuous basis to thicken residuals to an average solids concentration
of 7.0%. The County is committed to continue their annual sludge removal and land
application program during this interim period to prevent accumulation of biosolids in
the lagoon.

Mortality Data: Chronic Fathead Test
Process Flow Narrative Description
The Return Activated Sludge (RAS) is directed to the first cell of the anaerobic selector
to provide the RAS with additional denitrification time in an effort to create truly
anaerobic conditions prior to the introduction of the raw influent containing readily-
degradable soluble BOD. The screened and de-gritted influent is directed to the second
cell of the anaerobic selector, where it is commingled with Return Activated Sludge
(RAS) from the Enviroquip secondary clarifiers.
The treatment scheme applied at the Triangle WWTP includes Andritz Aqua Screen
continuous belt-type fine screens discharging to the influent pump station, which is
equipped with Fairbanks Morse Pumps. The Fairbanks Morse pumps lift the screened
influent to the upper treatment level where the Jeta vortex grit removal and flow
measurement units are located. After the two physical processes of screening and grit
removal, the influent is directed to the five-stage biological treatment process.
Each Kruger (a Veolia Water Systems Company) Modified A2/O treatment train includes
a three (3) cell anaerobic selector for phosphorous removal, a two (2) cell primary anoxic
zone for nitrogen removal, an oxidation ditch for aerobic BOD removal and nitrification
of ammonia, a two (2) cell secondary anoxic zone for additional denitrification, and re­
aeration prior to the four (4) 110-ft diameter Enviroquip secondary clarifiers.
The Durham Triangle WWTP is a 12 MGD Advanced Secondary Treatment plant with
integral Biological Nutrient Removal that discharges to Northeast Creek. In order to
produce the high-quality final product, the raw influent is subjected to a sequence of
individual unit processes ranging from fine screening to disinfection. Each unit process
has its own side streams and discharge by-products that must be processed or disposed of.
The Ondeo Degremont rapid sand filters polish the fines from the treated water. The
filtered effluent is then disinfected through the Trojan Ultraviolet Disinfection unit and
directed to the post aeration basin prior to stream discharge.
The forward flow continues on through the third cell of the anaerobic selector and
proceeds to the first cell of the primary anoxic zone. Nitrified mixed liquor recycled
from the aerobic oxidation ditch is discharged to the first cell of the primary anoxic zone,
as well. The primary anoxic zone provides the anoxic ambient conditions and carbon
source required to denitrify the nitrates recycled from the oxidation ditch.
The discharge from the oxidation ditches is directed to the secondary anoxic zone for
further denitrification. Methanol can be added to this unit to provide the carbon source
required to drive the denitrification reactions if the effluent nitrogen concentration is too
high. In addition, a “RAS Bleedoff” is incorporated that enables the Mixed Liquor
Suspended Solids (MLSS) concentration in the second anoxic stage to be increased. The
denitrified wastewater is re-aerated prior to discharging to the clarifiers, where the heavy
MLSS are separated from the clarified effluent and are returned to the head of the
process, as described above. The clarified effluent that discharges over the weirs is
directed to the tertiary Filters.

appearance and cleanliness of the Administration, Operations, and Maintenance Buildings in excellent
condition at all times, and shall provide those custodial services normally associated with maintenance
of a business office. Said custodial services shall include vacuuming, emptying trash, cleaning and
waxing tile floors, cleaning light fixtures and windows, cleaning walls and ceilings, and cleaning and
maintaining restrooms and locker rooms. Contractor shall also be responsible for preparing the
Conference Room of the Administration Building for meetings.
5.04 Drainage Channels - Drainage swales and channels within the plant shall be maintained free
of excessive vegetation, so as to allow unobstructed drainage of the plant or pump station site.
5.06 Gravel Road Maintenance - On an annual basis or as needed for access, Contractor shall
scrape and gravel roads and pull ditches. Contractor shall utilize an approved herbicide to eliminate
weeds as needed. Herbicide shall also be used to prevent growth of new weeds. Annually, Contractor
shall report to the County those areas of roads which appear to require major maintenance.
5.05 Paved Road Maintenance - On an annual basis, Contractor shall utilize an approved herbicide
to eliminate weeds in asphalt pavement and concrete walkways and shall mechanically scrape or trim
roadside plants away from asphalt pavement. Herbicide shall also be used to prevent growth of new
weeds. Cracks in pavement shall be sealed on an annual basis with an approved asphalt emulsion.
Annually, Contractor shall report to the County those areas of pavement which appear to require major
maintenance.
5.08 SCADA System - The Confractor will be responsible for the routine maintenance of the
SCADA system. The County will coordinate all improvements or enhancements with the Contractor
so that plant operations are not adversely impacted.
5.02 Pump Stations and Areas with Limited Landscaping - The landscaping in some areas of
County facilities consists of trees, shrubbery and non-irri gated native ground cover. Contractor shall
maintain trees and shrubs by regular pruning and control of weeds, within and up to six (6) feet
outside fences and shall replace any plants which die. Ground areas shall be mowed, weather and
ground conditions permitting, with sufficient frequency to limit height of weeds and grasses to a
maximum of six (6) inches at pump station sites. Trees and shrubs shall be pruned on a rotating basis
so that individual plants are pruned at an interval which does not exceed three years. All poison
oak/ivy at pump stations shall be promptly sprayed with an herbicide formulated to kill poison oak/ivy,
or removed manually upon its discovery.
5.03 Collection System and Force Mains - These areas will be maintained annually to a height of
twelve (12) inches by bush hog or other means necessary to allow Contractor to access facilities. Any
fallen trees or debris will be promptly removed from easements as soon as practical upon discovery.
5.10 HVAC Systems - The Contractor shall maintain all HVAC systems for the Administration
Building, Electrical Buildings, Pump Stations and Well House.
