SUBJECT: Advance Notice of Renewal Application Requirements
Permit NC0024201
Roanoke Rapids WWTP
Conduct four toxicity tests for an organism other than Ceriodaphnia and submit results with
your renewal application. The tests should be conducted quarterly, with samples collected on the
same day as your current toxicity test. Call the Aquatic Toxicology Unit at [phone] for
guidance in conducting the additional tests.
NCDENR
North Carolina Department of Environment and Natural Resources
Division of Water Quality
You are receiving this advance notice because your facility has a permitted flow at or above 1
MGD, or the subject facility receives industrial [pretreatment] waste water. If either of these
criteria no longer applies, contact the NPDES Unit before submitting a renewal application.
NorthCarolinaNaturally
The U.S. EPA revised and expanded the application requirements for municipal permits, effective August 1,
2001. EPA form 2A is attached to this Notice, and must be used for your permit renewal application. The
new application requirements mandate additional effluent testing:
1. Conduct three Priority Pollutant Analyses (PPAs) and submit results with your renewal
application. Collect samples for the PPAs in conjunction with sampling for your current
quarterly toxicity test. The new PPA requirements differ from previous versions. Each PPA
must include:
Analyses for all total recoverable metals listed in Part D of form 2A. This includes metals
that are not normally monitored through your NPDES permit.
Analyses for total phenolic compounds and hardness.
Analyses for all of the volatile organic compounds listed in Part D.
Analyses for all of the acid-extractable compounds listed in Part D.
Analyses for all base-neutral compounds listed in Part D.
Analyses for Total Mercury must be performed using EPA Method 1631.

If any wastewater discharge will occur after the current permit expires, this NPDES permit must be
renewed. Discharge of waste water without a valid permit would violate Federal and North Carolina law.
Unpermitted discharges of wastewater could result in assessment of civil penalties of up to $25,000 per day.
The pollutant and toxicity scans described above must accompany your permit renewal application,
or any major permit modification request. The Division cannot draft your permit without the additional
data. Any data submitted cannot be over 4 Yz years old, and must account for seasonal variation
(samples cannot be collected during the same season each year if collected over multiple years). If your
permit already contains a requirement for an annual effluent pollutant scan, additional scans are not
required [provided you have conducted at least 3 scans prior to submitting your application].
The following items are REQUIRED for all renewal packages:
A cover letter requesting renewal of the permit and documenting any changes at the facility since
issuance of the last permit. Submit one signed original and two copies.
The completed EPA Form 2A application (copy attached), signed by the permittee or an Authorized
Representative. Submit one signed original and two copies.
If an Authorized Representative (such as a consulting engineer or environmental consultant) prepares
the renewal package, written documentation must be provided showing the authority delegated to the
Authorized Representative (see Part II.B.ll.b of the existing NPDES permit).
A narrative description of the sludge management plan for the facility. Describe how sludge (or other
sohds) generated during wastewater treatment are handled and disposed. If your facility has no such
plan (or the permitted facility does not generate any sohds), explain this in writing. Submit one signed
original and two copies. This information can be included in the cover letter.

The Division of Water Quality has received your permit modification request dated May 24, 2006, for the
Roanoke Rapids Wastewater Treatment Plant. Permit modifications requesting the removal of an effluent
parameter from an NPDES permit is considered a major modification to the permit. Such a change, if
implemented, would subject the permit to the same public notice procedures as issuing a new or renewed
permit. In addition, because your facility is classified as a major municipal, any major modifications to
your permit would have to receive concurrent approval from the U.S. Environmental Protection Agency
(EPA). Given the above, and since your permit expires on March 31, 2007, and since the renewal process
is scheduled to begin within the next few months, this office will evaluate your request to remove the
mercury effluent limit during your NPDES permit renewal process. We can, however, at this time reduce
the measurement frequency requirement for the effluent and upstream mercury from weekly to monthly.
Accordingly, we are forwarding herewith the attached modified NPDES permit. Please insert the
attached permit pages into your permit and discard the old ones.
This permit modification 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. EPA dated May 9, 1994
(or as subsequently amended).
As a reminder, your permit renewal application is due to the Division postmarked no later than October 2,
2006, in order to satisfy the conditions of your NPDES permit.
If you have questions regarding any of the above, please feel free to contact Vanessa Manuel at 919/733-

This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
A. COMMENT: The laboratory has each analyst perform a verification of the DR 4000 manufacturers’
pre- programmed calibration.
REQUIREMENT: NCLC policy requires that the concentration of the blank must not exceed 50% of the
LOQ/MQL/PQL. The lab must obtain a signal in which the constituent concentration in reagent water is
2(1.645)s above the mean of blank analyses (Lower Limit of Detection). The constituent concentration
that produces a signal sufficiently greater than the blank, that it can be detected within specified limits,
by good laboratories, during routine operating conditions, is the Limit of Quantitation. Typically it is the
concentration that produces a signal 10s above the reagent water blank signal. In most cases, this

Weldon, NC 27890-
addition to
15A NCAC
REQUIREMENT: Each analyst must have there own daily or annual curve unless a pre-programmed
calibration is used. Pre-programmed calibrations must be verified annually with 5 non-zero standards
and a blank. A new calibration verification will need to be performed for each new lot of digestion
solution and each new lot of stock standard a new. Each analysis day, thereafter, include at least one
reagent blank and CCV (NC Policy defines as mid-range check standard same source as calibration
standards), with each digestion batch. In addition, analyze one known standard in
calibration standards each day samples are analyzed to document accuracy. Reference:
2H .0805 (a) (7) (B) and (I); SM 20th Edition 5220D.4C.
B. COMMENT: The laboratory uses a digested blank rather than an undigested blank
spectrophotometer. The laboratory must monitor the absorbance readings of the digested blank to
ensure the contribution to sample absorbance is at a minimum.
Page 2
Total Suspended Solids:
Total Residual Chlorine:
F. COMMENT: The laboratory has each analyst perform a verification of the DR 4000 manufacturers’
pre-programmed calibration.
REQUIREMENT: The analyst must analyze sufficient sample to get at least 1 mg of residue. "If weight of
captured residue is less than 1.0 mg, the sample volume must be increased to provide at least 1 mg of
residue." Ref: Methods for Chemical Analysis of Water and Wastes, Residue, Non-Filterable, Method
160.2
REQUIREMENT: Each analyst must have there own daily or annual curve unless a pre-programmed
calibration is used. Pre-programmed calibrations must be verified annually with 5 non-zero standards
and a blank. Each analysis day, thereafter, include at least one reagent blank and CCV (NC Policy
defines as mid-range check standard same source as calibration standards), with each digestion
batch. In addition, analyze one known standard in addition to calibration standards each day samples
are analyzed to document accuracy. Reference: 15A NCAC 2H .0805 (a) (7) (B) and (I);
C. COMMENT: The laboratory will need to consider increasing the ‘effluent’ sample volume filtered to
ensure an adequate amount of residue is retained on the filter. Otherwise, the reporting limit of the
procedure must be adjusted to account for the decreased filtration volumes.
E. COMMENT: The laboratory must evaluate procedures to determine why blank samples obtain an
appreciable amount of residue on filters. Analyst must ensure filters are washed thoroughly after sample
filtration to remove any dissolved material which would be mis-read as suspended. Procedures for
cooling and desiccating of samples to balance temperatures should be reviewed. When filters are not
allowed to cool sufficiently erroneous readings can be obtained due to the unstable temperatures.
D. COMMENT: Blanks periodically produce negative values which can be an indication filters are
insufficiently washed during the preparation procedure. Washing the filters removes any small fibers that
would otherwise wash from the filter when a volume of water is vacuumed through the filter, therefore
producing a negative result.
requires an absorbance value greater than 0.005 units, preferably greater than 0.010 units. Ref:
Standard Methods, 20th Edition - Method 1010 C. and 1030 C.
REQUIREMENT: Insert disk with wrinkled side up in filtration apparatus. Apply vacuum and wash disk
with three successive 20-mL portions of reagent-grade water. Continue suction to remove all traces of
water; turn vacuum off and discard washings. Reference: SM 20th Edition 2540D 3a.
REQUIREMENT: Dissolved solids are the portion of solids that passes through a filter of 2.0pM
nominal pore size under specified conditions. Suspended solids are the portion retained on the filter.
For samples high in dissolved material thoroughly wash the filter to ensure removal of dissolved
material. Each sample requires close attention to desiccation after drying. Minimize opening desiccator
because moist air enters. Reference: SM 20th Edition 2540A section 1, 2 and 2540D section 1b.
REQUIREMENT: Choose sample volume to yield between 2.5 and 200 mg dried residue. If volume
filtered fails to meet minimum yield, increase sample volume up to 1L. Reference: SM 20th Edition
2540D 3b.

ranges from 18” to 30”.
The collection system consists of approximately 130 miles of sewer lines. The sewer lines
within Roanoke Rapids, Gaston and all sub-divisions, which connect to the two main
Interceptors, range in size from 8” to 12”. There are two main Interceptors transporting
waste to the WWTP.
The Chockoyotte Creek Interceptor handles the south side of Roanoke Rapids and three sub­
divisions, Lake View Park, Greenbriar and Lincoln Heights, outside the Roanoke Rapids city
limits. The Interceptor begins east of Zoo Road. There is one primary basin pump station
along the route. Pipe size ranges from 12” to 30”.

Creek Outfall.
Preventive Maintenance of at least four hours a week cleaning sewer mains has also been
a good tool in reducing sewer backups. The use of degreasers in pump stations on a
regular schedule has proven to be very effective in preventing lift station down time.
Also all pumping stations are checked and cleaned a minimum of twice weekly.

The Fat, Oil and Grease (FOG) program initiated in 1995 has been a good tool in
preventing Sanitary Sewer Overflows (SSO’s).We also have a fulltime employee for the
FOG Program to inspect all records and grease traps. He also educates all restaurants
about grease and how it effects our sewer lines. The use of local newspaper for FOG
program educational ads and the distribution of brochures to restaurants and fast food
businesses have also been effective. Inspection of records and grease traps is an ongoing
measure to prevent SSO’s.
The wastewater treatment plant is rated at 8.34 million gallons per day (MGD). Peak flow is
rated at 12.5 MGD.
During these processes solids are removed from two locations. Primary clarification removes
settleable solids from incoming wastewater to an anaerobic digestion unit. Here the solids, in
the absence of oxygen, receive pH adjustment, mixing, and heating to produce a stabilized
material. Once the solids are stable, excess water is decanted and returned to the plant for
further treatment. The stabilized, thickened solids are treated with lime for odor control then
removed to a holding tank to await land application.
Treatment processes at the wastewater plant include grit and rag removal. This is followed by
primary clarification, trickling filter biological secondary treatment, activated solids
treatment, secondary clarification, final effluent chlorination/dechlorination processes, and
final pH adjustment.
There are two pumping stations in the wastewater plant distributing wastewater into and
through the plant. Of these two pump stations, one has the capacity to pump 20 MGD and the
other 27 MGD respectively. Also, to aid these two pump stations; a storm water pump station
has been installed. This station intercepts rainwater, an unnecessary load to the treatment
plant, and removes it before entry to the plant. It has the capacity to pump 11.5 MGD. In
conjunction to these two pump stations there is one pump station with capacity of 21 MGD to
remove treated flows from the plant in the event of high river levels preventing normal gravity
flow discharge. Various others pumps and mixers are located throughout the plant for process
control.
Secondary clarification removes solids from the activated solids process. Here, solids in the
presence of oxygen, ph control, and mixing, accumulate in excess. They are removed,
chemically stabilized, and added to a holding facility. All stabilized solids are analyzed and
land applied according to their nutrient value, ceiling and accumulative requirements.
A. Description of overall 12 month performance, noting highlights and deficiencies:
1. C.S.:
The Roanoke Rapids Sanitary District’s collection system received its inaugural permit in
2001 under the North Carolina Environmental Management Commission Department of
Environment and Natural Resources system wide wastewater collection system­
permitting program.
F. Description of WWTP:
The SC ADA system that monitors all lift station 24 hours
prevented lift station overflows.
a day, 365 days a year has
The permit also contains a daily maximum residual chlorine of 28 micrograms per liter
(ug/l), a weekly mercury maximum of 868 nanograms per liter (ng/l), and ph must be
maintained between 6 and 9.
The increase may be due to significant rainfall amounts the latter half of 2006, resulting
in higher flows as a result ot inflow and infiltration. Also, one of the wastewater plants
non-significant industrial users added an additional shift.
Current plant capacity is 8.34 million gallons per day (MOD) with a peak flow of 12.5
MOD. For 2006 the yearly average low flow was 3.7 MOD with minimum of 2.1 MGD.
The yearly average high flow was 6.0 MGD with a maximum of 9.1 MGD. The yearly
average total flow was 4.5 MGD or 54% of the plant capacity. This is a 8.9% increase
over the previous year.
Under the current permit, the District has a weekly effluent total suspended solids (TSS)
limit of 45 mg/1 and a monthly limit of 30 mg/1. Also a weekly carbonaceous
biochemical oxygen demand (CBOD) limit of 37.5 mg/1 and a monthly limit of 25 mg/1.
The yearly average for TSS was 17.6 mg/1 and CBOD was 4.9 mg/1. Using yearly
average influent values for the same parameters this calculates to a 90.3% and 96.1%
removal rate respectively. The permit requirement is 85%.
In 2006, the District continued to be very active in maintenance issues and concerns. The
WWTP spent in excess of $745,000 on maintenance and repairs to equipment, supplies
and materials necessary to operate equipment and capitalized monies to replace and
upgrade equipment.
Some of the repairs and upgrades in 2006 include the following.
Grit Removal. The back -up grit removal process underwent major repairs. It is critical
for the protection of downstream equipment. On line since the early 1960’s, some of the
original equipment was still in use. The concrete collection area was showing severe
"scabbing” or wear. It was coated with an epoxy system to buildup and protect the
remaining concrete. The sweeper collection mechanism, it’s support structure and work
deck, all made of carbon steel, was rebuilt. Ail parts were replaced with stainless steel.
The deflector plates used to slow the flow of water down to allow grit to settle out, were
also made of carbon steel and had severely deteriorated. They were replaced with
stainless steel. The screw removal system on-line since the early 1980’s was made of
carbon steel and had severely deteriorated as well. A new system, completely fabricated
of stainless steel, was installed. As well, the suction and discharge piping of the screw
removal system was a combination of carbon steel and PVC. The piping was replaced
with stainless steel. The motor which operates the sweeper collection mechanism had
-3 -
In response the District has increased staff, critical parts inventory, equipment inventory,
made plans to better address extreme conditions, upgraded critical equipment, planned
back up or alternative operations, and requested better responsiveness from sub­
contractors. Responses are continuous and increasing.
The District is keenly aware of and has been very responsive to increasing environmental
awareness. House Bill 1160, Clean Water Act of 1999, ratified by the North Carolina
General Assembly on July 20th and signed into law July 21st by the governor, has
heightened this awareness. This bill codified as Chapter 329 session laws became
effective October 1999.
2. WWTP:
Overall performance for 2006 was good. There were no NPDES permit limits violations.
(See below) There were no monitoring or reporting violations.
Rotary Distributor Number Two. Installed several years before number one, number two
rotary distributor has a defective bearing that had to be replaced. A crane had to be
rented and the unit completely disassembled. The new bearing was installed, which took
several laborers a couple of days.
Effluent Polymer Project. There has been a polymer feed system located near the
effluent end of the treatment process for several years. It is used for solids washout under
varying conditions. The original system was set up hurriedly in response to tliis
condition and without much thought and preparation. Because this process is of
intermittent use and used only in specific situations, this system had a lot of down time.
-4 -
Rotary Distributor Number One. The existing unit was approximately 25 years old. It
was constructed of carbon and galvanized metal. The environment had deteriorated it
severely. The replacement unit is made entirely of stainless steel and should hold up to
the elements better. Hydraulics through the unit are used to propel it. This is an
electrical cost saving. There are pumps associated with the distributor for use during low
flows or when other operational parameters call for the need. The replacement unit was
designed to operate at lower flows to negate the need for pump assistance under these
circumstances. Increased preventative maintenance scheduling, more frequent arm
flushing and orifice cleaning should maximize the money spent on the distributor in
return of longevity.
Influent Pump Station Pump Controller. This system operates pump sequence and speed
between four pumps. The pumps are 25, 40, and two 60 horsepower. The sequence and
speed depends on the amount of flow coming into the plant. The controller installed in
2006 has a software program which makes the system more reliable and easier to adjust.
Also, the system was designed with a minimum amount of fail points and a maximum
amount of dependability. It has a primary water level sensing device with two
independent back-ups. The system is has battery back-up. In the event of power loss, it
will keep running. If the controller system senses any kind of problem, it will switch to a
back-up controller automatically and provide notification of the change. The entire
system is SCADA compatible. Operational information and alarms are monitored via
computer located in the operations building control room.
been subjected to water submersion and burned up over the years during periods of high
flows. To remedy this situation, the drive mechanism was retrofitted with an extended
sprocket system and chain. This allowed the motor to be relocated above the flood area.
Secondary System. The secondary biological treatment system consists of three 500,000
gallons tanks and two one million gallons tanks. It is the second biological process in the
treatment system. These tanks are routinely drained one at a time and inspected for
repairs. In 2006, these tanks were randomly drained and inspected. One of the 500,000
gallon tanks, aeration basin number two, had some deteriorated flanges. The flanges are
located on pipe work that supports management of the system. A failure during operation
could have been detrimental to overall treatment process. Flanges were ordered and
replaced. The system is back fully operational.
Trickling Filter Isolation Valves. These valves isolate the trickling filters allowing
preventative maintenance or maintenance to be done to the rotary distributors. Before the
valves were replaced, the filters had to be bypassed, pumped around for work to be
performed. Setting the pump up and connecting pipe was very labor intensive and took a
good while to accomplish. Pump rental was expensive, also. When bypass pumping
around a filter for isolation, extreme care had too be taken to avoid a spill. Not only
during the pump time but also in the dismantling of the bypass pump pipe. The
installation of these valves turned a very labor intensive job into a relatively simple one.
It also eliminated the pump rental cost and the chance of spillage. The valves were
stainless steel. They should be more durable and stand up to the environmental
conditions better. To help keep these valves in good operable shape, they are exercised
on a regular basis.
-5 -
12” pump installation. The 12inch pump installed at the head-works of the plant in 2000
remains a valuable tool in preventing spills. In the event of high flows or maintenance
repairs, water can be removed to two abandoned secondary clarifiers. These clarifiers
were taken off-line in the early eighties after plant upgrades. They were originally used
for stabilized biosolids storage. The capacity was increased by extending a wall up from
where the weir overflows were when used as secondary clarifiers. This increased the
storage capacity of the two tanks to 750,000 gallons. After a dedicated biosolids tank
SC A DA (Supervisor Control and Data Acquisition) system work. SC AD A is a
computer-based program. It brings site information into the central operations center.
SCADA is a useful tool by providing monitoring information to be used for more
efficient plant operation. It also brings remote site alarms into the operations center,
which provides better control over plant problems.
Million Gallon Tank (MGT). The million gallon tank (MGT) is used in the biosolids
stabilization process. It stores all stabilized solids until moved out for the land
application process. The tank is constructed of bolted in place, seamed glass lined
panels. It also has a cathode rod floor system to help attract chemistry that would attack
the panels. The manufacturer suggests preventative maintenance inspection on 10 year
intervals. The tank was recently 20 years old and an inspection was scheduled. The
inspection revealed the need for some repairs. All the horizontal and vertical seams
needed to be stripped of old coating, treated with a rust inhibitor, and recoated. Also, the
protective cathode system needed too be replaced. On-site staff was to prepare the tank
by emptying the contents of the tank and doing a general cleaning. Plant staff was also
responsible for renting a crane for placing equipment in and back out of the tank. Staff
also rented a scissor lift to reach all the seams to be repaired. (The tank is nearly 20 feet
tall.) This was followed up with power washing the seams. The manufacturer’s
contractor was hired to complete the seam work and cathodic system installation. Also
repaired was a small leak that had developed along one of the seams. In addition, some
minor dings along the lower outside panels were patched. In all the repair process lasted
approximately three weeks at a cost of about $21,000. This price does not include staff
labor.
When needed, extensive clean up and/or parts replacement was required each time of
need. This was an awkward situation because when running was necessary, it was
needed immediately. To remedy this situation, the entire process was reworked to
provide better, more efficient and more reliable service. The pump and gearbox were
mounted on a horizontal stand. Then a bulk storage tank was added for more chemical
capacity. This setup provided for flooded suction to the pump making it easier to feed to
the pump for dispensing polymer. The bulk tank also had a mixer installed to keep the
polymer from separating and being less effective. Added to the bulk tank as well were
high and low level cutoffs with a level indicator. The high cutoff was to prevent
overfilling and spills. The low level cutoff was to prevent the dispensing pump from
running dry and burning up. A second pump was installed to the process. It is used
strictly for the transfer of the polymer from delivery barrel to the bulk storage tank. The
gearbox on the dispensing pump was reduced to make the pump more efficient. The
dispensing pump was also installed with a coupling system. This along with a back-up
pump minimizes downtime in the event the on-line pump goes down. Finally the
building that houses the system was fitted with a heater for winter time use and a
ventilation system for summer. This setup provided a more environmentally friendly set
up for polymer.
SCADA work continued in 2006. The area of emphasis was the emergency generator
transfer switch and main motor control center. After the installation of a piece of
analyzer equipment in this area, it enabled much information to be monitored via
computer. Work also included improving the monitoring computer located in a control
room. Many graphs and trend charts were added to further help with monitoring the
status of plant site information. The monitoring computer was also reconfigured to make
it more user friendly.
The biosolids land application program ran smoothly in 2006. In the required annual
report to North Carolina division of Water Quality (NCDWQ) and the Environmental
Protection Agency (EPA), there were no deficiencies, spills, or violations. This included
-6-
This flood pump station has a back-up pump valving and pipe work installed independent
of this station. In the event of catastrophic flood pump or flood pump control panel
failure; treated water will continue to be removed from the plant. The pump is capable of
treating 8.5 million gallons per day or about 4 million gallons more than the average daily
flow in 2006. Plant maximum rated capacity is 8.3 million gallons per day. In 2006 the
pump was covered to help keep it protected and in better working condition. Lighting
was provided for nighttime operation. Also, a battery charger was installed to keep the
pump ready for use. The pump is exercised regularly to ensure performance.
Another means of spill control is with a back-up generator. The wastewater plant must
continue to run in the event of power interruptions from the power-supply company.
Power interruption can occur from equipment failure, road accidents, and weather events,
such as ice storms, electrical storms, tornadoes, and hurricanes. AlOOOkilo-watt
generator is on site for events and can supply enough generated power to run the entire
plant. In 2006 power supply was interrupted on 1 occasion for a total of 20 minutes.
With the use of the back-up generator power, 36,110 gallons of wastewater was
prevented from spilling. This along with the wastewater stored in equalization totals
31,546,236 gallons. Again at the average 2006 daily of 4.5 MGD, this would be 7.0 days
of flow.
was constructed, the two abandoned tanks were dedicated to spill containment. Once
stored, wastewater can be returned to the plant with an existing pump station. Some pipe
work has been added to this station and depending on conditions, water could be returned
as the tanks are filled. This further increases holding capacity or downtime, during
maintenance and repairs. In 2006, 5,139,911 gallons of wastewater were stored. Since
setup in 2000, 31,510,120 gallons of wastewater have been prevented from spilling. At
the average flow of 4.5 MGD in 2006, this would be 7.0 days of flow.
The wastewater plant is also equipped with emergency flood pumps. These pumps are
used in the event of high river levels, which prevent normal gravity flow out of the plant.
Without them, treated wastewater would have no way of exiting the plant and
consequently would flood the plant, causing extensive damage and long recovery. These
pumps are maintained and exercised on a regular basis to ensure proper operation for
times of urgency. This station is also equipped with local and remote SCADA high level
alarms. These alarms provide notification in the event of station failure. Enough
notification time is allowed to take remedial action before plant damage occurs. The
alarms are checked on a regular basis as well.
The emergency generator is also used to curtail. The District is under contract with
Dominion Power. From May 16th through September 30th (summer curtailment) and
from December 1 through March 3 lst (winter curtailment), Dominion can request the
wastewater plant to supply its own power for parts of the day during peak demand.
These requests usually come on the hottest days of summer and the coldest days of
winter. Dominion can then send power that the District would normally use to other
places of need. Winter requests are usually from 6am to Ham (5 hours) and summer
from 2pm to 9pm (7 hours). The contract is limited. In the winter requests to curtail are
limited to 13 or 65 hours and summer 19 or 133 hours. In 2006 the wastewater plant was
called to run all 19 times during the summer curtailment. There were no winter calls.
The District does incur the cost of diesel fuel. However, the rate structure the wastewater
plant has because of the contract off sets this cost and provides electrical energy savings.
An added benefit of this program is that it provides a means to exercise the generator.
This keeps the generator in better running condition and exposes any potential problem.
It would be better to find out a problem during a curtailment than an actual power outage.
By having the generator under a contracted quarterly preventive maintenance program
hopefully problems will be minimized or eliminated.

In 2006, industrial users were required to apply for permit renewal by December 2. Two
significant industrial users and 4 non-significant users applied for renewal. One
significant user did not apply due to a plant closing.
234 stabilization events at 12,750 gallons per event. This is 64% of the days in a year.
The wastewater plant has entered into agreement with area farmers for the use of their
land for biosolids application. The farmers in turn receive the nutrient value, moisture
content, soil remediation, and lime, which is a by-product of ph control in the treatment
process of the biosolids. If necessary, additional lime can be applied. There are 3100
acres, consisting of 128 fields, available in Halifax, Northampton, and Warren Counties.
All acreage was inspected, approved, and permitted by the State of North Carolina.
Using EP A approved treatment processes, 3,412,500 gallons of stabilized biosolids were
safely applied to area lands, consisting of 6 fields and 243 acres, for beneficial reuse.
Cost of this application process was approximately $73,000. Cost of treatment to
stabilize solids is separate. Land that grew fescue, rye, and wheat were applied to. The
amount applied in 2006 is up nearly 17% from the previous year. Charges for application
are based on gallons. In an attempt to save application costs, biosolids are thickened as
much as can possibly be handled. The removed water is returned to the treatment plant.
Also, once biosolids are placed in storage for land application, water is further separated.
This water along with environmental water (rain, snow, etc) is decanted and returned to
the treatment plant. In 2006, 532,548 gallons was decanted, at savings of $15,656.91.
Although 3100 acres of land is permitted and storage of 1,000,000 gallons is available, at
times application is difficult due to weather conditions, crop status, and crop rotation.
Owning land would provide an outlet for these times. In 2004, the District purchased a
suitable land application site. It is located in Northampton County where the District
already has farmer owned land permitted. In 2006, the contract for the biosolids land
application program with the current contract applier was to expire. In an attempt to
obtain the best price for the application process, bid specifications were drawn up. The
bid process attracted four contractors, who submitted bid packages. After analysis, an
award was offered to Synagro, the current contract applier.
Since purchasing the land investment improvements in 2006 occurred to ready the area
for application of biosolids. Some of these improvements are additional fence and
gating, additional rock for access road, weed removal from fence, tree removal from pond
dam, fertilizing, disking, Bermuda sprigging and removal of an abandoned house.
Improvements were in excess of $26,000. Also, the current land application permit was
modified to include this land for biosolids application. As a result of this, a
neighborhood meeting was held in October to introduce and explain the process of
biosolids application.
In 2006 the industrial pretreatment program had oversight of three significant industrial
users. One user has a categorical discharge pipe. Four non-significant industrial users
are permitted to send flow to the wastewater plant. Significant and non-significant status
is determined in part by the volume of flow discharged and the pollutants in the
discharge. The pollutants, carried by certain industrial wastes, determine the categorical
status of an industry. In 2006 there were no significant industrial users in significant
non-compliance; a status based on the number and types of violations of a permit. There
were three violations of permits. There was one pH, and one Oil and Grease violation.
One significant industry was purchased by another company and one significant industry
was closed, ceasing discharge. One non-significant industrial user added another shift to
their work week.
On March 16, 2006, a luncheon workshop was held in order to provide industries with
information regarding the permit renewal applications and permit conditions. The two
significant industrial users and one non-significant user had representatives present. Two
staff members with the Division of Water Quality were also present.
Another testing requirement of the NPDES permit is the annual priority pollutant analysis
(APPA). As indicated, it is an annual test that checks the effluent for conventional and
non-conventional compounds, total recoverable metals, volatile organic compounds,
acid-extractable compounds, and base-neutral compounds. These substances, if found in
sufficient quantity, could be harmful to the wastewater plant, receiving stream, and the
public. To date, no substances have been found in significant quantity to cause harm.
The test is done seasonally over the term of a five year NPDES permit.
The pretreatment annual report (PAR) was submitted to the state pretreatment unit on
February 7, 2006 and was accepted as having met ail criteria required by pretreatment
regulations. A letter of April 3, 2006 was received stating review of the PAR indicates
the report in good order and satisfied the requirements of the North Carolina Pretreatment
Program.
In 2006, money was budgeted to create a new position. Under the pretreatment program,
a pretreatment technician was established to manage the FOG ordinance. In July, the
position was filled. Since then several steps of the ordinance have been put into place.
Site visits of local restaurants began with introduction of the coordinator. The purpose of
the coordinator was explained. Inspections were begun to see if grease interceptors were
in place, installed properly and if regular cleaning with record retention was taking place.
Site drawings of the restaurants were also made. And, a database was started for tracking
all of the visitations and recording all findings. In addition, a public education program
was introduced. Advertisements in the local newspaper and on television were started.
The wastewater plant now has a general storm water permit. It was received through an
application process as required by the North Carolina Division of Water Quality. A

A requirement of the wastewater plant through its NPDES permit is quarterly chronic
toxicity testing. The test involves using a predetermined amount of effluent along with a
macroscopic organism. Ceriodaphnia are placed in the effluent and must survive and
reproduce for a specific length of time. Results of the test are either pass or fail. A pass
indicates the absence of substances in the effluent which may be harmful or threaten
aquatic life. The wastewater plant has been required to test for chronic toxicity since
April of 1993. To date only one test has received a fail result. This occurred in July
2001. In addition, as a part of permit renewal in 2006, an additional species must be
tested. The waste water plant used fathead minnow. The test was performed seasonally
and the results, all favorable, were submitted with the permit renewal information.
The North Carolina Division of Water Quality Laboratory Section inspected the
laboratory on June 6, 2006. The laboratory is now implementing all recommendations
and comments outlined in the inspection report. A letter dated July 20, 2006, from the
laboratory section, stated all requirements had been met.
In 2006, the wastewater NPDES permit came up for renewal. North Carolina Division of
Water Quality requires specific information and data for analysis in structuring a new
permit. The submittal package is due 180 days before permit expiration. All required
information was submitted in October 2006.
Last year the Sanitary District adopted a Fat, Oil, and Grease (FOG) ordinance. Its
adoption was a direct result of the NPDES permit process which required the
implementation of measures to address sanitary sewer overflows (spills). Fats, oils, and
grease (FOG), if placed in the sanitary collection system can over a period of time build
up and clog pipes causing spills.
The North Carolina Division of Water Quality performed its annual inspection of the
pretreatment program April 27, 2006. A letter of May 2, 2005 was received
complementing the program on the organization, documentation, and time management
instituted within the program.
Permit limit violation

In part, due to the awareness and training from the safety program, there were no loss
work days in 2006. There were also no reportable incidents or accidents.
requirement of this permit is a written storm water management plan. The plan is used to
evaluate potential pollution sources and to select and implement appropriate methods to
prevent or control the discharge of pollutants to stormwater runoff. As a part of the plan,
semiannual preventative maintenance evaluations and semiannual inspections of site
runoff areas are required.
The District has an emergency response team. The formation of the team arose from
chemicals, chlorine, and sulfur dioxide stored on site. Another factor for its formation
was the lack of any other agency in the immediate area to deal with these chemicals. The
team meets and has drill practices regularly. The team is fully equipped and trained to
handle emergencies which may arise from the use of chlorine and sulfur dioxide.
The Division of Water Quality conducted their annual review of the wastewater plant on
November 14, 2006. A comprehensive site inspection was conducted. The site
inspection went well. The evaluation report received on November 17, 2006 stated the
plant was in compliance. There were no recommendations or corrections. The report
also noted that the wastewater treatment plant had established a sound storm-water
program and was implementing it.
After years of preparation, the District called OSHA and requested consultative
inspections to help maintain a safe work place for its employees. After a series of
inspections from OSHA safety and health officers, the District met all requirements of
compliance by correcting all hazards identified during consultative visits and by
developing an occupational safety and health management system. Once met, the
District was eligible for the SHARP (Safety and Health Achievement Recognition
Program) Award. Again in 2006, the wastewater plant requested an OSHA consultative
inspection. Deficiencies were exposed and corrected. As a result, this year marked the
fifth straight year the waste water plant was in the SHARP Program. With this
achievement, NCDOL (North Carolina Department of Labor) grants exemption from
programmed OSHA compliance inspections for a specified period of time. It is a
compliment to the dedication and continued hard work of the administration and staff It
serves also as a testament to the commitment of the company for the protection of the
employees and surrounding community.
The safety program within the District is very active and assertive in its approach to the
protection of the employees and surrounding citizens. The program consists of a safety
officer, safety committee, incident/accident committee and appeals committee. The
safety officer sets up the monthly safety meetings, coordinates the activities of the safety
committee, keeps up with safety regulations, and many other various safety activities.
The safety committee prepares safety policy programs and updates current ones. They
also do site inspections and produce potential hazard punch lists. The safety committee
and safety officer also keeps up with and prepares for updating regulations and
integrating new regulations of OSHA. The incident/accident committee reviews all
potential accidents and accidents. The appeal committee follows up the safety committee
recommendation at the request of an employee. The attempt is to minimize the
seriousness of an accident and ultimately prevent accidents.

A valve exercise program is now employed. It keeps valves in good working order. In
the event of routine maintenance, equipment problems, or emergencies, valves used to
address these issues are in a state of readiness.
Isolation valves were installed in 2006 on both trickling filters. Now removing these
units for maintenance and repairs will negate the need for bypass pumps and piping. This
will eliminate the chance for spills while pumping and dismantling after use.
The Stormwater Pollution Prevention Plan (SPPP), implemented in 2006, will be a
valuable tool in identifying deficiencies. It incorporates awareness and training not only
to all plant personnel, but also vendors and contractors. The plan allows for scheduled
identification of deficiencies before they become problems.
There are various alarms throughout the plant site. However, if they malfunction they are
of no value. In an attempt to keep functioning alarms, they are tested on a regular basis.
The rag auger installed a few years ago has a bottom bearing which leaks. The leak is on
top of the concrete pad where it is mounted. The leak could not be stopped. So there was
a deflector shield made and installed to divert the leakage back into the sewer system.
A polymer feed pump station remains on line to help with solids washout at times of high
flows. In 2006, this pump station was rebuilt and completely re-modified. Now this
station is much more user friendly, has more chemical capacity, and is much more
efficient. In addition, operational strategies have been put in place to minimize solids
wash out at times of high flow. And as described in performance section “II”, a 12”
pump is in place to retain flows that might otherwise reach surface water. This setup
continues to be a valuable tool each year in preventing spills. And in retaining high flows
in equalization tanks this helps with solids wash out also.
The Fat, Oil, and Grease (FOG) program, which began as a committee, advanced to an
ordinance, and now has a full-time employee to administer the program. The goal is to
prevent FOG from entering the collection system causing blockage problems resulting in
spills. The wastewater plant will benefit by having less FOG to handle and chemically
treat.
Identifying and eliminating inflow and infiltration (I&I) is an on-going and difficult task.
It is important to stop or minimize to take unnecessary flows off of the treatment plant.
However, it is also important to address because excess I&I can “dilute” incoming waste.
Diluted wastewater makes it more difficult to meet percent removal requirements (85%)
of the plants permit. In 2006, more areas were identified and addressed to help resolve
this problem.
