Subject: Waiver of Monthly Reporting Requirement
NPDES Permit NCO023230
Richland WWTP
Onslow County
The Division has reviewed your request to suspend submission of monthly Discharge Monitoring Reports
(DMRs).
After considering the recommendations of the staff in the Wilmington Regional Office, we have agreed to waive
the requirement to submit monthly DMRs for the subject facility, .effective July 1, 2015. The DMRs up through
(and including) June 2015 should be submitted as usual.
Be advised that if and when any wastewater discharge occurs, the discharge must be monitored as per the terms
of the NPDES permit and other applicable rules or statutes. Please keep the Division apprised of any pertinent
developments that arise regarding this facility, especially if the discharge is re -activated.
While requirements for operator visitation, monitoring and reporting are being waived, you are still required to
pay the Annual Administering and Compliance Monitoring Fee that is associated with this and all NPDES
permits.
If you have any questions, or if you wish to request rescission of either permit, contact Sonia Gregory at

Subject: Re: Richlands decommission process

For a reporting/monitoring suspension we just need a letter in writing from the permittee.
Doesn't look they are requesting rescission, if that were the case, normal procedure is regional staff
does a closure inspection to confirm the plant is decommissioned and then the permittee requests
rescission in writing to the division and Charles handles closing the permit file/records.

A.Procedure to Determine if Annual Average Limit Required:
Step 1- WQBEL Evaluation
• Evaluate need for Water Quality Based Effluent Limit (WQBEL)
• Calculate Allowable mercury concentration using dilution (12 ng/1 x 7Q10 dilution factor)
• Compare Annual effluent concentrations to Allowable Conc. for each of last 5 years
• If any Annual Avg > Allowable Conc., then add Annual Avg WQBEL.
Step 2- TBEL Evaluation
• Evaluate need for Technology Based Effluent Limit (TBEL)
• Compare all individual values to TBEL of 47 ng/l
• If any single value > 47 ng/l, then add Annual Avg TBEL of 47 ng/l.
Step 3- Compare WQBEL to TBEL
• If data triggers need for WQBEL and TBEL, select most stringent of the two limits.
• The Annual Avg limit will be capped at 47 ng/1 based on TBEL.
Step 4- If NEW limit, delay effective date
• Addition of new limit will become effective in 5�h year of permit, with mercury minimization plan
development/implementation required for first 4 years (see MMP below).
B. Mercury Minimization Plan (MMP). If an MMP is required, add the following Special Condition to
the permit:
A(x). Mercury Minimization Plan (MMP). The permittee will develop and implement a mercury
minimization plan during this permit term. Guidelines for MMP development will be placed on the
Division website following a stakeholder review process. The MMP should place emphasis on
identification of mercury contributors and goals for reduction. Results shall be summarized and
submitted with the next permit renewal. The MMP must be available for inspection on -site.
C. New/Expandine Dischareers- will be allowed as long as the overall aggregate point source load
allocation is not exceeded.
D. Special Situations- Additional site -specific information, such as fish tissue and water column data
when available, will be considered in assigning limits and MMP requirements. Also, limits > TBEL may
be considered on case -by -case basis due to extenuating circumstances.

BACKGROUND
The Onslow County Water and Sewer Authority (ONWASA) own and operate a 0.25 MGD
wastewater treatment facility that serves the majority of the Richlands community, population
3,098. The Richlands facility discharges treated 100% domestic wastewater to Squires Run, a
class C-NSW water in the White Oak River Basin.
To minimize operation and retain its Class II designation, the Permittee requested and received
conditional approval in 2007 not to be required to use the Total Phosphorus (TP) chemical
treatment system until such time compliance required TP removal. Staring with this permit cycle
in 2008, the facility has successfully met its TP compliance with no chemical treatment. The
long range plan is to divert this flow to a new non -discharge regional facility and rescind this
permit.
A sewer extension moratorium was issued in 2004. A request to remove the moratorium was
denied in 2008. Several improvements to the collection and metering system to reduce influent
flow, and investments in engineering evaluation and property for an upgraded treatment facility
were made during the permit cycle. Three approvals to allow acceptance of additional influent
sources were made, two were addressed in SOCs. ONWASA is finalizing plans for new regional
non -discharge facilities that will at some point accept Richlands influent and thus allow this
permit to be rescinded. In May 2012 the Permittee petitioned the Division to rescind the 2004
moratorium which was granted.
Fact Sheet
NPDES NC0023230
Page 1 of 3

HISTORY
2007 — Permit renewed, added seasonal weekly NH3-N limits, quarterly TP limit, and stipulation
that as long as no chemical TP treatment used the facility treatment class would remain
Class II. Additional directions were given if chemical TP treatment was anticipated by
Permittee.
2008 — Approved sewer extension to accept wastewater from new elementary school.
2009 — Issued two SOCs for sewer extensions.
2011 — Mechanical failure of surface rotor resulting in several non-compliance events.
2012 — Sewer extension moratorium was rescinded. Requested and received additional
information on treatment components.
PROCESS
Untreated domestic wastewater enters the facility headworks where it is screened, flows through
a grit removal system, and is collected in the influent pump basin. An influent composite sampler
collects samples. There is an influent flow meter. The influent pumps flow is distributed to the
dual oxidation ditches which use surface rotors. There are two chemical additions system
available that can inject chemicals into the influent flow to adjust pH and to enhance total
phosphorus (TP) removal. By agreement the TP addition system is not used.
The combined flow from the ditches enters a distribution box which is used to control the flow to
the dual clarifiers. From the clarifiers the combined flow enters the dual traveling bridge tertiary
filters via a distribution box, recombines and continues to the contact basin where chlorination
followed by dechlorinaton treatment is conducted, and then enters the post aeration basin with
dual aqua jet agitators. The continuous backwash water from the filters is recycled back to the
influent pump basin. As the treated wastewater a is a aeration basin it flows through the
effluent flow meter channel and continues to the tfall. An effluent composite sampler collects
samples. Gx� #�
As needed wasted sludge is collected and stored in the aerobic digester. The digester can be
decanted and the wastewater recycled or pumped directly to a truck for disposal off site.
Since 2008 there were 22 recognized limit violations; 12 for BOD, 5 for Flow, and 5 for NH3-N.
There were several unreported data events. The mechanical failure of the surface rotor and
subsequent plant upset in March 2011 was responsible for 6 of the limit violations. ONWASA
was assessed and paid $2,936 in penalties for violations during this permit cycle.
DATA REVIEW

Instream data was compared to its matching effluent parameter, some correlations were
observed.
PERMITTING STRATEGY
There are no changes recommended for the effluent limits. As a minor discharger, this facility
was previous approval to be limited toxicity -wise for NH3-N and TRC, and is not subject to
additional toxicity testing unless it expands or additional toxicants are identified. The NH3-N
limits defined for summer/winter are based on BAT criteria and the original 0.25 MGD model
recommendation.
The current stipulation for the use of chemical treatment for TP removal will be stated in a new
reopener special condition that will be added to this permit.
The Mercury TMDL Reopener special condition will be added to comply with US EPA
recommended strategy.
Instream Data Impact
The current requirements were established in 1987. Temperature, Dissolved Oxygen, Total
Nitrogen, TP are measured routinely at one designated point upstream and two points
downstream from the discharge into Squires Run. The May 2010 through June 2012 data was
reviewed to determine the impact of the effluent to Squires Run. As anticipated with the high
IWC % this discharge does impact the monitored parameters. The planning section was
contacted and no changes to the current instream monitoring scheme were recommended. Will
continue instream monitoring program.
SUMMARY OF PROPOSED CHANGES
In keeping with Division strategies the following will be incorporated into the permit:
• A Special Condition to define Permittee responsibilities and to define permit
modification when chemical treatment for TP removal is anticipated will be added.
• A Special Condition for a Mercury TMDL Reopener will be added.
• The Supplement to Cover Sheet component narrative will be updated.

8.5.2 Nutrient Sensitive Waters Discharge Strategies
Waters classified as Nutrient Sensitive Waters (NSW) are subject to wastewater discharge
limitations (refer to 15A NCAC 213 .0223 for specifics on NSW rules). The New River was
classified as NSW in 1991. Previous White Oak Basin plans (1997 & 2001) recommended the
following as part of the New River NSW strategy to reduce point source contributions of
nutrients to the upper New River estuary:
■ Existing facilities with permitted capacity, of 0.05 MGD or greater should continue to
receive total phosphorus (TP) limits of 2.0 mg/l.
■ New and expanding facilities should continue to receive TP limits of 0.5 mg/l.
■ New and expanding facilities greater than 1 MGD should receive total nitrogen limits
(TN) similar to Camp Lejeune of 5.0 mg/1(summer) and 10.0 mg/1(winter).
■ All facilities without limits will be required to monitor TN and TP.
It is also recommended that no new discharges be permitted and expansions of existing facilities
only be allowed if there is no increase in permitted loading of oxygen -consuming waste.
Refer to Chapter 2 for discussion on the success of this NSW strategy for the New River.
8.5.3 Permitted Non -Discharge Waste Management Strategies
New development activities in coastal areas frequently rely on non -discharge systems for
wastewater treatment and disposal. These treatment systems are designed to satisfy at least the
minimum permitting requirements for protection of the surface and ground waters that they
could potentially impact. Permitted non -discharge facilities can be a good alternative to

The Richlands W WTP was designed for an effluent flow for an effluent flow of 0.250 MGD. All of the influent flow enters
the plant first thru a Lakeside 12MS Microstrainer and then a Pista Grit Chamber. The flow gravity feeds to the influent
pump station, 2 Gorman Rupp T4 centrifugal pumps. The influent pumps send the flow to the extended aeration oxidation
ditch. The influent flow is mixed with the Return Activated Sludge (RAS) in the oxidation ditch which then gravity feeds
thru the Mixed Liquor distribution box to two identical Envirex Tow-Bro clarifiers. The clarified effluent flows thru the
effluent distribution box to two identical Aqua -Aerobics sand filters. The filtered effluent flows to the chlorination chamber
where it is chlorinated by gas chlorine and then to the de -chlorination chamber where the chlorine is neutralized by gaseous
sulfur dioxide. The effluent is aerated by two identical aqua jet aerators before it gravity feeds to Mill Swamp. The RAS
flows to an individual vault for each clarifier then to a collection vault where the Gorman Rupp T4 pump send it
either to the oxidation ditch for re -use or to the digester for disposal.

SUBJECT: RICHLANDS WWTP SEWER MORATORIUM
Permit No. NCO023230
Wastewater Collection System Extension
Onslow County
Dear Mr. Walker:
William G. Ross, Jr., Secretary
Coleen H. Sullins, Director
In response to the request dated November 7, 2007 to the Division for lifting of the current moratorium
on the subject facility and sewer collection system imposed in July 2004, we offer the following
comments.
In 2004, the Wilmington Regional Office recommended that a moratorium be imposed at the 90% level,
pursuant to 15A NCAC 2T .0118 (previously 2H .0227) . even though reported flows for 2003 were well in
excess of 100% of the facility's design capacity. This option allowed the Permittee at the time, the Town
of Richland, to pursue permitting and construction approvals to lift the moratorium while construction
was initiated to meet their future needs. However, when flows are reported above 100% the Division
may impose a statutory moratorium pursuant to NCGS 143-215.67 that requires a new or expanded
facility to be constructed and placed into operation prior to lifting of the moratorium. In some cases,
the statutory moratorium can be further increased to prevent new connections for service from new
construction by preventing issuance of building permits.
Your request provided documentation about multiple changes made to flow measurement equipment
beginning in April 2006 and ending in August 2007 with these changes determined to lower the reported
flow rates by approximately 30% from previous levels, The analysis to determine the impact on flow
readings from measurement adjustments should have also included a correlation between billable
water and plant flow before and after changes using months with comparable rainfall events. In
addition, it was indicated that the facility began using treated effluent for plant woshdown and
dechlorination beginning in late September 2007 eliminating an estimated 33,000 gallons per day at
flow contributed by potable water use at the facility.

RICHLANDS WWTP SEWER MORATORIUM
January 28. 20D8
Page 2
ONWASA submitted corrected monthly monitoring reports (DMRS) for December 2006 through April 2007
using the 30% reduction. While accepting those new values to be accurate, and further considering
the DMRs for May through November 2007, the average flow for the facility remains at 80% of its design
capacity for the post 12 months during a period of excessive drought. It the some reduction is applied
to the previous 6-month period of June -November 2006, which was also abnormally dry but had a few
rainfall events, then the facility would have exceeded 80% & 90% during two months and would have
exceeded its design capacity during two other months with the worst being 124%.
It was indicated in the response that some repairs of the sewer system have been completed to address
inflow & infiltration (W), but no data was collected before and after such repairs for quantification. It is
our understanding that more extensive repairs are slated for the upcoming year or so, based on a
comprehensive study recently completed by Rivers & Associates. An analysis of flow data for June
through December of 2006, which was a period of more normal rainfall and water table level, indicates
that I& continues to be a major source of flow at the facility. More recently, daily flow was doubled by
a 1-inch rainfall event in late October 2007. This appears to be attributable to inflow and indicates that
repairs to the collection system are still needed. It also indicates that higher influent flow rates could be
expected during periods of more normal rainfall and water table level.
Based on these considerations, it is determined that it is not appropriate to lift the moratorium at this
time. Based on the criteria for lifting a moratorium imposed when actual flow rates exceed 801/o of
design flow limits, the moratorium could be lifted with the approval of an engineering proposal that
presents a clear path for expanding the treatment and disposal system to support continued growth. If
more normal weather patterns occur and flows increase beyond 90%, which is anticipated, then the
moratorium would be back in place until permits have been issued for expansion. Another mechanism
would be entering into a Special Order by Consent (SOC) that can cover a period of up to 5 years, The
SOC would provide ONWASA the limited ability to increase its customer base tributary to the Richlands
facility while moving toward actions to meet the area's future needs. ONWASA would need to outline
what specific actions need to be accomplished to further reduce I&I, and pursue applicable approvals
for construction of a new treatment facility & collection system infrastructure to transport wastewater to
the new facility. In addition, it would include timetables for initiation, submittals, completion, etc. A key
feature of the SOC is that limited flow allocation can be provided during the life of the SOC based on
completing specific action items.

Dear Mr. Powell:
The Division of Water Quality (the Division) hereby issues the attached NPDES permit for the subject
facility. We issue this permit pursuant to the requirements of North Carolina General Statute 143-
215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated May 9, 1994, or as subsequently amended.
Phosphorus Removal - WWTP Grade II vs. Grade III. As stated in our letter of September 26, 2007,
the Division must deny your request for "optional use" of the existing phosphorus treatment chemical feed
system. Your need to remove phosphorus would mandate an automatic treatment -plant upgrade from
Grade II to Grade III and would require stricter compliance conditions and an increase in monitoring
frequencies, in accordance with statewide policy for receiving streams classified as Nutrient Sensitive
Waters (NSW).
Understanding that you have never used your existing phosphorus treatment system, the Division has
renewed this permit as a Grade II facility, but only with the stipulation that ONWASA continues to
refrain from using chemical treatment to remove phosphorus. Please note that use of this chemical -feed
system is a violation of this permit. In the future, if Richlands WWTP needs to remove phosphorus to
remain in compliance, ONWASA must apply to modify this permit and must receive authorization in
advance from the Division.
If any parts, monitoring frequencies, or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing, upon written request, within thirty (30) days
following receipt of this letter. You must submit this request in the form of a written petition, conforming
to Chapter 150B of the North Carolina General Statutes, and file it with the office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is
made, this permit shall be final and binding.

FOR NPDES PERMIT DEVELOPMENT — COMPLEX EXPIDITED
NPDES Permit NCO023230
INTRODUCTION
Onslow Water and Sewer Authority (herein referred to as ONWASA or the Permittee) requires a
National Pollutant Discharge Elimination System (NPDES) permit for its Richlands Wastewater
Treatment Plant (WWTP). The Permittee's 5-year NPDES permit to discharge treated wastewater to the
surface waters of the state has expired, and they have requested renewal from the Division of Water
Quality (the Division). This Fact Sheet summarizes background information and rationale used by the
Division's NPDES Program to determine permit limits and conditions.

FACILITY RECORDS REVIEW
Facility Description. Richlands WWTP (Table 1) is a 0.250 MGD Publicly Owned Treatment Works
(POTW) utilizing the following treatment system components:
o mechanical screen
o manual bar screen with grit collection and composite sampler
o variable -speed influent pumps
o dual -train oxidation ditch with dual disk -rotor aerators
o chemical feed system to remove phosphorus (not in use — requires permit modification)
o dual final clarifiers with attached scum pit
o sludge return pump station
o aerobic sludge digester/sludge holding facility
o dual tertiary package filters
o chlorine disinfection and dechlorination
o post aeration
o standby power generator
CORRESPONDENCE
Permit History. Division records for Richlands WWTP date from 1992 (Town of Richlands) with the
most recent permit becoming effective August 1, 2002 and expiring July 31, 2007. Upon request, the
Division transferred ownership to ONWASA on July 26, 2005.
Prior to applying for renewal, ONWASA submitted a letter requesting the Division, "to allow for optional
use" of the phosphorus removal system rather than "continuous use." The Permittee contends that they
have never needed or used this phosphorus removal system since its construction in 1993.
The Wilmington Regional Offic (W;aR supeecct that phosphorus treatment has not been needed
because the Permittee's influent hasen regularly diluted with stormwater due to si ificant sewer -
collection system inflow and infiltration (FI), and under drought conditions, may°neekpD Osp� imo %`
treatment to stay in compliance. ONWASA has assured the Division that it shall diligently continue to,
identify and correct inflow and infiltration.
PERMITTING APPROACH -- RENEWAL SUMMARY
WWTP Classification — Grade H verses Grade 11- Permitted flow (0.250 MGD) and a Total
Phosphorus (TP) limit (2.0 mg/L) togethe sugges that the Division should upgrade the current WWTP
classification from Grade H to Grade III, accor mg to current Nutrient Sensitive Waters (NSW) policy.
Moreover, the Division must deny the Permittee's request for "optional use" of its phosphorus treatment
system because, with the need to remove phosphorus, comes an automatic treatment -system upgrade from
Grade II to Grade III. However, the Division will renew this permit as a Grade II, but only with the
stipulation that the Permittee refrain from using the chemical feed system, and apply to modify this permit
in advance of implementing chemical feed phosphorus treatment. —L,1,� �Q
Fact Sheet
Renewal -- NPDES NCO023230 �

Permit modification will mandate treatment -plant Grade III permit limits, monitoring conditions, and
appropriate operator certifications. As stated above, the Division will renew this permit with a Grade II
classification provided that the Permittee remains in compliance with the existing TP limit. Given the data
supplied by the Permittee suggesting relatively low TP effluent averages during 2006 (1.63 mg/L) and
2007 (0.94 mg/L to date), compliance is likely.
Treatment of TP requires Grade III limits and conditions including 3/Week monitoring and a potential
certification upgrade for the Operator in Responsible Charge (ORC). This will be summarized in the
permit cover letter.
Effluent Monitoring This facility to remain Grade II with the understanding that
the existing TP treatment system has never been used. If TP
treatment is needed in the future, the Permittee shall apply to
the Division (in advance) to modify this permit and expect to
comply with Grade III limits, monitoring, and appropriate
operator certification.

COMPLIANCE REVIEW
The Division has added Weekly Average Ammonia (NH3 as
N) limits (6.0 mg/L summer; and 12.0 mg/L winter) to this
permit, in accord with statewide guidance.
The Permittee monitors one location upstream and two
locations downstream of the outfall. Parameters of concern
include Total Nitrogen, Total Phosphorus, Temperature and
Dissolved Oxygen. No changes recommended for renewal.
None. This facility discharges <1.0 MGD and processes
100 % domestic waste. No changes recommended.
Verifying Existing Stream Conditions. This facility discharges to Squires Run [stream designated
19-31, a C-NSW classified waterbody tributary to the New River within the White Oak River Basin.
While this receiving stream is not listed as an "impaired" [not 303(d) listed], it is tributary to the New
River classified Nutrient Sensitive Waters (NSW).
Compliance, Pretreatment, and Toxicity Testing. Per Division guidance, this facility does not
conduct Whole Effluent Toxicity (WET) testing because its influent is 100 % domestic and its
permitted flow (0.250 MGD) is less than 1.0 MGD. It has no pretreatment program. According to the
Basin -wide Information Management System (BIMS), this Permittee received no violations from
January 2004 through August 2007.
Effluent Data Review. The Division reviewed 43 months (January 2004 through July 2007) of effluent
monitoring reported in monthly Discharge Monitoring Reports (DMRs). DMRs appeared regular,
thorough, and complete. Total flow for this time period averaged about 0.244 MGD or about 98 % of
permitted capacity. The Division suspects that UI problems in the sewer collection system may have
caused a significant portion of this total

Dear Ms. Crawford,
Our National Pollutant Discharge Elimination System (NPDES) permit currently lists the
chemical feed system for phosphorous removal as part of the treatment process. During a
recent NC DENR annual compliance and permit renewal inspection it was noted that this
facility does not use the chemical feed system for phosphorous removal. The system has never
been used since it's installation in 1993.
This facility has no problem meeting the quarterly phosphorous limits during weekly
sampling. Our average 2006 effluent phosphorous concentration was 1.63 mg/l. The average
thus far for 2007 is 0.94 mg/l.
We request a minor modification to the National Pollutant Elimination System (NPDES)
permit to allow for optional use of the phosphorous removal system rather than continuous
use.
We appreciate the time and effort of the NPDES Unit to consider this permit modification
request. We thank you for your consideration and we look forward to your response. Please
contact me if any additional changes need to be made. I may be reached at 1-910-340-9207.
Thank you for all the information you provided.
Respectfully,

Significant inflow and infiltration is evident based on a study of daily flow data documented on the
daily monitoring reports submitted by the Town of Richlands. In April 2006 the flow meter was
upgraded from a bubbler type to an ultrasonic. The flow meter was checked three times for accuracy.
Monthly average flows increased approximately 82% on average between June 2006 and March
2007, compared to that same time period one year earlier (June 2005 through March 2006). Daily
flows are far in excess of what had ever been measured before by the bubbler system indicating the
bubbler system had severe limitations with accuracy during high flow scenarios. The inaccuracy of
the bubbler method resulted in an overall lower monthly average reported on DMRs prior to April
2006. From March 2005 to February 2006, the average annual flow was 0.205 MGD, whereas the
period from March 2006 to February 2007, the average annual flow was 0.31 MGD or 105,000
gallons higher. Daily maximum flows as high as 0.948 MGD has been recorded.
The permit renewal application identified 75,000 gpd as the averge number of gallons per day of
inflow and infiltration (I and 1) that flow into the treatment works. This value needs to be verified by
the Division's method for calculating I and I. The Town should submit water billing records in order
for infiltration to be determined. DMR flow data following a one inch rain event should be
compared with 275 gpd per capita served in order to determine whether inflow is excessive. The
population served by the Town of Richlands WWTP is 1071(based on permit renewal application).
Based on the data provided, the flow per capita would be 0.295 MGD. The average flow over the
past 6 months is 0.374 MGD. That is an excess of 79,000 gpd. This year has been a relatively dry
year, therefore the average daily excess is more likely due to infiltration rather than inflow. During
rain events, the flow through the facility is usually greater than 0.50 MGD. Inflow is extremely
excessive compared to infiltration. It appears the Town has accounted for the flow contribution from
infiltration, but has not identified the contribution from inflow.
The wastewater treatment plant is located in a low area near Squires Run. Often during heavy rain
events, the creek rises requiring access by boat. One manhole at the WWTP typically overflows
during heavy rain events. The Town is currently smoke testing the collection system in an attempt to
identify the source for infiltration.
Low concentrations of pollutants may be attributable to dilution rather than adequate treatment
considering the flow was much higher than what the Town thought due to the inaccuracy of the flow
measuring device utilized prior to April 2006. The limited capacity of the plant and the tremendous
hydraulic loading occurring during rain events would likely result in partially treated wastewater
being discharged to the receiving stream, thereby increasing the overall loading of pollutants to the
White Oak River Basin.
The Wilmington Regional Office recommends reissuance of the permit in accordance with the White
Oak River Basin Plan permitting strategy provided no significant adverse public comment is
received. The Wilmington Regional Office also requests that the recommendations provided herein
are considered in the reissuance of Permit No. NC0023230.

The Richlands WWTP receives flow from the town of Richlands thru a 12" force main. The flow proceeds thru the headworks which includes a mechanical bar screen
and a grit remover. The influent pumps are rated for 175 gpm (slow speed) and pump the influent flow to the 2 channel oxidation ditch. The oxidation ditch, which is
rated for 0.55 MGD, mixes the incoming flow with the returning RAS to provide the necessary F/M ratio. The mixed liquor leaves the oxidation ditch, is split evenly
by the mixed liquor distribution box to the 2 identical 0.625 MGD clarifiers. The effluent flow leaves the clarifiers and flows thru the tertiary sand filters to the chlorine
contact chamber. The effluent is chlorinated then dechlorinated and finally aerated before being discharge via the outfall to Squires Run. The RAS flow is pumped
either to the oxidation ditch or wasted to the digester. Water is removed from the settled sludge and returned to the headworks for reprocessing.

Attn. Maureen Crawford (NPDES)
1617 Mail Service Center
Raleigh, NC 27699-1617
RE: Richlands Wastewater Treatment Plant
NPDES Permit No. NCO023230
Dear Ms. Crawford:
Office of the
Director for Operations
Francis A. Sanders, Jr., P.E.
We are writing to request that the Division of Water Quality (DWQ) lift the
moratorium that was placed on this facility and the Town of Richlands by the Department's
"Demonstration of Future Wastewater Treatment Capacity" letter to the Town of Richlands
dated July 22, 2004. The letter stated that the Richlands wastewater treatment plant (WWTP)
had exceeded the 90% threshold for the 2003 calendar year. Based upon that finding, the
letter stated that DWQ would be unable to approve any further sewer line extensions for the
WWTP until such time as the facility would be in compliance with the Rule.
Changes to the Wastewater Treatment Plant
Since this letter was received and ONWASA assumed the responsibility for operation
of this facility, we have accomplished the following changes to the wastewater treatment plant
operation:
April 13, 2006 Due to concerns with operation of the bubbler flow measuring system,
ONWASA replaced the bubbler air tubing.
May 17, 2006 Due to continuing concerns that the bubbler system was no longer
working correctly, ONWASA replaced the bubbler flow measuring system with an
ultrasonic flow measuring system. It was then noticed that the flow readings appeared
to be higher than normal even considering the amount of rain.
November 2, 2006 The flow meter was relocated to the far end of the chlorine contact
chamber due to concern about the sulfur dioxide system flow causing turbulence and
errors in the flow readings.
June 4, 2007 After discussing the situation with Tom Moore, DWQ, Leo Green,
Green Engineering, and ONWASA staff, it was determined that the 24-inch
rectangular weir plate was too large for the most accurate flow measuring given the
228 Georgetown Road. • P.O. Box 1415 • Jacksonville, NC 28540 • Tel [phone] • Fax [phone]

plant's flow range. It was decided to replace the 24-inch rectangular weir plate with a
12-inch rectangular weir plate.
June 5, 2007 A 12-inch rectangular weir was installed and the flow measuring system
was recalibrated. At that time, flow readings began to read closer to what was
expected for the time of year and amount of rainfall.
June 14, 2007 Due to concerns about water usage, the potable water meter to the
plant was replaced with a new meter. Water usage began to be tracked on a daily
basis. It was found that potable water usage inside the plant was approximately 37,000
to 38,000 gpd. This usage was divided between grit chamber wash down,
chlorination/dechlorination process water, and miscellaneous water usage throughout
the plant.
July 18, 2007 ONWASA submitted a letter requesting remission of the Notices of
Violation and Assessment of Civil Penalties for Violation to DWQ for the months of
December 2006 through April 2007. Subsequently, DWQ agreed with the requested.
August 17, 2007 After further discussions and analysis, it was decided that a V-notch
weir would provide an additional increase in flow measurement accuracy. The 12-
inch rectangular weir was replaced with a 90 degree V-Notch weir. The flow meter
was relocated to the center section of the effluent channel for better readings and then
recalibrated.
September 20, 2007 As a result of determining the high usage of potable water in the
treatment process (see June 14, 2007, shown above), the chlorination and
dechlorination (sulfur dioxide) feed systems were changed to submerged jet pump
ejectors to allow for the recirculating use of treated effluent. This resulted in the
reduction of approximately 33,000 gallons of potable water usage and effluent
discharge from the plant.
Quantification of Flow Reductions
A review of the flow data during the period outlined above indicates that by relocating
the flow meter, changing from a 24-inch rectangular weir to a more accurate V-notch weir,
and the elimination of the potable process water, used for chlorination/dechlorination, it has
resulted in a reduction of effluent plant flow of at least 67,000 gpd. The breakdown of the
reductions is as follows:
Moved flow meter (11 /2/07)
Changed to V-notch weir (8/17/07)
10,000 — 100,000 gpd*
24,000 gpd (Exhibit No. 1)* *
Eliminated chlori/dechlorination water (9/20/07) 33,000 gpd (Exhibit No. 2A & 2B)**
*Varies with flow through the plant, increasing with higher flows (see previously approved remission request)
"These flow reductions were not included in previously approved remission request.
228 Georgetown Road. • P.O. Box 1415 • Jacksonville, NC 28540 • Tel [phone] • Fax [phone]

Onaoina Infiltration/Inflow Work
During the period of the improvements listed above, ONWASA was also identifying
(through smoke testing) and removing both public and private sources of inflow. Because this
work was done over a fairly long period of time, we are unable to estimate the actual flow
reduction that resulted.
In order to make further improvements on the treatment process, we currently have
our consultant, Rivers & Associates, Inc., working on the design of a sewer rehabilitation
project. We have applied for and received approval of the Preliminary Engineering Report
and application for a loan of $2.8 Million from CG&L, pending completion of the final design
of the project.
Onslow County Schools
Onslow County Schools, to meet the unprecedented growth in the County and in light
of the most recent announcements by the Department of Defense that 8,000 to 10,000
additional troops are coming to the Marine Bases in our area, plans to build several schools.
One of those schools currently under design is to be located near the Town of Richlands
(Gum Branch Road Area Elementary School). Onslow County Schools currently has an
agreement with the City of Jacksonville for the reservation of 9,600 gpd wastewater capacity
in the system. However, the cost of the facilities needed to convey the wastewater to the
City's system will cost an estimated $1.38 Million. This cost exceeds the County School's
budget for such facilities. Therefore, Onslow County Schools has been looking at other two
other alternatives. One alternative is to construct its own on -site land treatment facility. This
alternative may be the least expensive but has the disadvantage of requiring the consumption
of approximately 21 acres of land more suitable for a higher use, the need for an equalization
basin using land that is needed by the school, and resulting in yet another package plant in a
County that is already over -burdened with package plants. ONWASA has already been asked
by the State and is in the pursuing the transfer of the Centerline, Inc. Springdale Acres
package plant to ONWASA's ownership and operation. The second alternative is to construct
facilities that will convey the school's wastewater to the Richlands wastewater treatment
plant. The advantage of this alternative is that eliminates the need for a package plant, avoids
the consumption of land for the equalization basin and on -site land treatment system, and
costs less than the Jacksonville alternative due to the proximity of the school to the Richlands
plant. The agreement with Jacksonville expires on December 31, 2007 and Onslow County
Schools must soon make a decision on how they are going to treat their estimated wastewater
of 9,600 gpd from the school.
Summary
Based upon the work that ONWASA has completed to -date by: 1) improving the
accuracy of the flow metering at the plant, 2) by removing the potable water from the
treatment process, and 3) by conducting the in-house inflow identification and removal
project, we have reduced the effluent flow from at the plant by over 67,000 gpd. As shown
on Exhibit No. 3, we have made a comparison of before and after these flow reductions were
228 Georgetown Road. - P.O. Box 1415 - Jacksonville, NC 28540 - Tel [phone] - Fax [phone]

made. It shows that we have significantly lower plant effluent flows. Based on anticipated
flows for the remainder of the year, we have estimated the final monthly average for 2007 to
be approximately 182,000. This flow is well within the 90 percent flow (225,000 gpd) of the
permitted flow of 250,000 gpd. As shown in Exhibit No. 3, we believe that had these changes
and modifications been made prior to 2007, we may well have seen an average flow for 2007
of approximately 148,000 gpd.
We have made significant strides in reducing the Richlands wastewater treatment plant
flows. We will continue to make strides with the ultimate goal of building a new treatment
facility and the elimination of this discharge to the New River. Onslow County Schools is
coming to a financial crossroad to choose one alternative or another in order to keep
progressing with their much needed Gum Branch Road Area Elementary School. We do not
want another package plant in the County that ONWASA will ultimately have to take over.
We are trying to regionalize wastewater services and lifting the moratorium will go a long
way in accomplishing that goal. It is for these reasons that we ask that you lift the
moratorium on the Richlands wastewater treatment facility and the Town of Richlands. We
ask that you lift the moratorium upon completion of your review of this data and not delay the
determination into 2008.
Thank you for your consideration of this request. Should you have any questions or
need additional information, please do not hesitate to contact us. If you would like to meet
with us to discuss this further, we will be happy to do so.

Dear Mayor Trott:

William G. Ross.lr., Secretary
North Carolina Department of Environment and Natural Resources
Alan W. Klimek. P.E. Director
Division of Water Quality
The application for a Special Order by Consent requesting an additional 75,000 gallons per day of additional flow
from the Richlands WWTP (NC0023230) has been reviewed along with some engineering calculations that have
been provided by your engineer (Mary Sadler). A review of the daily monitoring reports between September 2004
and June 2005 show fluctuations in flow from 0.127 to 0.550 MGD on a daily basis, which indicates inflow and
infiltration continues to be a problem for the Town of Richlands. The average flow between this same time period
ranged between 0.271 (September 2004) to 0.169 MGD (October 2004). The Town has been actively pursuing
repairs and must continue to reduce the flow to the plant from 1/1 to make available flow that could be allocated to
new developments. In September 2004 the Town received an NOV for exceeding their flow limit. Since then
there has been only one other flow violation, which occurred in January 2006 (enforcement pending).
The Town's request for a re -rate to 0.325 MGD (once the final engineering calculations are officially submitted)
appears likely. An upgrade at the headworks (grit removal) of the facility will be required, as the facility has
bypassed the headworks directly to the oxidation ditch during high flow events. If the re -rate is granted, the
additional effluent discharge from a re -rate of the facility capacity must be disposed of by some other means than
surface water discharge (surface irrigation or reuse). The Town should consider implementing flow equalization
to help normalize the flow. If the site has room for potential upgrades, it should have room to provide flow EQ.
The Wilmington Regional Office is not in support of granting the requested increase of the effluent discharge by
75,000 gallons to 0.325 MGD to the surface waters of the state. Should you have any questions or concerns
regarding this correspondence, please call me at 910-796- 7399.

Greetings!
Yesterday Ed Beck, Dean Hunkele and myself met with officials from ONWASA regarding
an SOC request and some discussions pertaining to the moratorium they were placed
under back in 2003. They are a 0.25 MGD facility that discharges to C-NSW waters
(Squires Run) stream index 19-3 which discharges to the New River. They are in the
White Oak River Basin. They have been under maratorium due to flow violations (8
out of 12 months in 2003 and 3 out of 12 months in 2004). 2003 was a very wet year
for the eastern coast , while 2004 was much much drier. The Town has done some work
on their collection system to reduce I/I, however they are not confident that their
efforts have adequately addressed I/I and know more efforts are needed. They want
the moratorium lifted based on better results in 2004 and 2005. Our comments in the
meeting were to the effect that we would like to see that their efforts have resulted
in I/I reduction.
They also would like to enter into an SOC to allow them to have their permit limit
for flow "temporarily" increased by 75,000 gallons (from .25 mgd to .325 mgd) to
accomodate some promises they made to some local developers. The promises made are
intended to help fund efforts to continue to address I/I and to help fund a WWTP
expansion. They intend to discharge the 75,000 for as long as the SOC is good and
when the SOc expires, will have implemented reuse capabilities for that additional
flow. In other words, they are not looking for an expansion in flow for the NPDES
permit, just temporary increase to get the revenue to fund the WWTP expansion whose
additional flow will not go to surface waters, but non discharge.
So, all that being said. . . shall I forward a copy of their application to you
today?? And is there language somewhere that allows a permittee to gain flow when
they have corrected I/I say 4 to 1 or 3 to 1, in other words, for every 4 or 3
gallons of I/I eliminated, we give them 1 gallon of flow???
I told them they would need to provide an EAA. I talked to Tom Belnick about this
yesterday morning and he recommended the EAA be done and sent in, does that need to
come in with the SOC? This one is a little strange compared to other SOCs. I don't
believe additional flow is allowed in the White Oak River basin which is where this
facility would discharge to due to the tough condition of this basin.
Thanks for taking the time to read this lengthy message.

The Town of Richlands has mailed two letters to the Division of Water Quality (DWQ) in
regards to issues at the Town's Wastewater Treatment Plant (WWTP). Both letters requested
an action from the Division. The first letter, dated March 24, 2005, concerned a request for a
waiver of the moratorium at the WWTP. The second letter, dated April 14, 2005, concerned a
request for a NPDES permit modification to remove the tertiary filters from continuous
service to optional service. The Town wishes to remove the barriers to positive and forward
growth in the community, and both letters address issues that are important to this effort.
Since the Town of Richlands has made several and interrelated requests to the Division over
the last few months, we thought it might be simpler to arrange a meeting with Division staff
to discuss the avenues that the Town could pursue to resolve these issues. Please let us know
the date and time convenient to DWQ to have this meeting.
We appreciate the time and effort of DWQ to help us with our concerns and requests. Please
do not hesitate to call myself (910-455-0722 ext. 239) or Mary Sadler with ARCADIS (770-

RE: Request for Permit Modification
Town of Richlands Wastewater Treatment Plant
NPDES Permit No. NCO023230
Dear Mr. McIntire:
Our National Pollutant Discharge Elimination System (NPDES) permit currently lists the
tertiary sand filters as a part of the treatment train, operating continuously with the rest of the
process. The total suspended solids (TSS) load from the secondary clarifiers to the filters is
minimal. Our secondary clarifiers were conservatively designed such that they are under -
loaded hydraulically, and hence they perform extremely well (per a Capacity Analysis and
Expansion Alternatives Investigation, ARCADIS).
We cannot operate our filters with regular backwash frequency because of the low influent
TSS. When backwashes do occur, the result is an increased hydraulic load to the headworks
with minimal solids being returned to the system. Furthermore, our staff must bypass the
filters during heavy rain events to prevent overflows, and the additional hydraulic load from
the filter backwash exacerbates the problem. Our facility meets the TSS permit limits
without the operation of the filters. Our average 2004 effluent suspended solids
concentration was 3.2 mg/l.
The use of the filters on a continuous basis, as currently permitted, imposes unnecessary
operating costs with minimal benefit to the facility. Therefore, the Town of Richlands
respectfully requests a minor permit modification to change the operation of our tertiary
filters to optional rather than continuous. The Wilmington Regional Office is willing to
support our request for this change, per a Compliance Inspection Report dated March 4,
2005. We recognize that this request may result in increased monitoring frequency for TSS
in the revised permit.
1 /2

We very much appreciate the time and effort of the NPDES Unit to consider this permit
modification request. We thank you for your consideration and we look forward to your
response. We will be happy to provide additional information. Please do not hesitate to call
myself or Mary Sadler with ARCADIS (770-431-8666) if you have any questions.

Town of Richlands Wastewater Treatment Plant
NPDES Permit No. NC0023230, White Oak River Basin
Dear Mr. McIntire,
Per a letter from the Division of Water Quality (DWQ) dated July 22, 2004, the Town of Richlands
Wastewater Treatment Plant (WWTP) was placed on a sewer line extension moratorium due to the
facility exceeding the 90 percent flow threshold for the 2003 calendar year. In 2003, the average yearly
flow was calculated to be 109.8 percent of the plant's capacity of 0.25 million gallon per day (mgd). The
letter also stated that DWQ would not approve any future sewer line extensions until compliance with
the 80/90 Rule was achieved. In order for the Town to attain compliance under the 80/90 Rule, plans for
a plant expansion must be in place or a detailed justification must be made to DWQ based on past
growth and future growth projections and/or a conservation plan or specific measures to achieve flow
reduction.
The Town of Richlands respectfully requests that DWQ waiver the moratorium at the Richlands WWTP.
First, the Town has implemented an aggressive Infiltration and Inflow (I/I) program that has successfully
reduced the 2004 yearly average flow to 83 percent of plant capacity. Second, the Town of Richlands, in
conjunction with the planning efforts of the Onslow Water and Sewer Authority (ONWASA), is in the
process of preparing a capacity alternatives analysis study for our WWTP. We consider these two
actions to be in compliance with the requirements of the 80/90 Rule.
First, we have implemented an aggressive 1/I program over the last several years aimed at reducing flow
to the plant. We have historically directed our resources to correcting the I/I problem rather than pursue
plans for a plant expansion. We have completed several successful I/I projects in our jurisdiction that
have reduced our I/I to the plant. In March 2002, the North Carolina Rural Economic Development
Center (NCREDC) awarded us a Supplemental Grant for a manhole and sanitary sewer rehabilitation
project in an existing development between Church and Wilmington Streets. This project was finished
and closed out in August 2002. In February of 2004, the NCREDC awarded us a $40,000 Capacity
Grant to assist the Town in more planning efforts in support of water and wastewater projects. This
planning study started in July of 2004. A crucial part of the Capacity Grant study was the
commissioning of Rivers and Associates in late fall of 2004 to perform rigorous 1/I field testing to further
identify key areas for rehabilitation. This work is in progress, with anticipated completion in the Spring
1/2

of 2005. In addition, our staff has been actively working to identify inflows to the plant and several of
these problems were corrected in November 2004, particularly after a flow violation due to 1/I in
September 2004. In summary, we have 1/I rehabilitation efforts that are in progress, but our past work
has successfully reduced our 2004 flows to 83 percent of our WWTP capacity.
Second, ONWASA has commissioned ARCADIS to complete a Capacity Analysis and Expansion
Alternatives Investigation for our plant. This study is an extension of the planning efforts by ONWASA
for Onslow County per the County's Resources Management Plan (ARCADIS 2003). Growth
projections show that the County is growing at a modest rate of 2 to 3 percent per year. In support of this
study, we requested speculative limits for a plant expansion in November 2004 to Squires Run Creek.
Although we have not received a formal response from DWQ, we were verbally told that additional
NPDES discharges or expansions were not allowed in the White Oak River Basin due to the Nutrient
Sensitive Waters (NSW) status of Squires Run Creek. Hence, we are pursuing re -use and land
application opportunities in our service area to accommodate a plant expansion for growth until 2015.
This Capacity Analysis and Expansion Study should satisfy the requirements of the 80/90 Rule. We
expect this study to be completed in April 2005.
Our facility has historically been in compliance with our NPDES limits with exception of flow in wet
weather events. However, our 1/1 efforts to date have been successful in reducing flow to the plant.
Additionally, we are pursuing a plant expansion to accommodate our expected growth to 2015. We will
be submitting the Capacity Analysis and Expansion Alternatives Investigation to DWQ for review and
approval. We feel that we are in compliance with the 80/90 Rule and we are taking positive steps to
improve the hydraulic situation at the WWTP. A waiver of the moratorium will enable us remove the
barriers to positive and forward growth in our community while we plan for the next 10 years.
We very much appreciate the time and effort of DWQ to consider this moratorium waiver. We thank
you for your consideration of this request and we look forward to your response. We would be happy to
provide additional information or to meet with you to clarify any issues. Please do not hesitate to call
myself (910-324-3301) or Ross Stroud with ARCADIS (919-854-1282) if you have any questions.

Gregg Whitehead

The Onslow Water and Sewer Authority (ONWASA) has retained ARCADIS to
complete a wastewater treatment plant capacity analysis and expansion alternatives
investigation for the Town of Richlands Wastewater Treatment Plant (WWTP). The
current NPDES permit allows a discharge of 0.25 mgd into Squires Run, a class
C-NSW water in the Cape Fear River Basin. The Town of Richlands WWTP
exceeded the 90 percent flow threshold in 2003 (15A NCAC 02H .0223).
In July 2004, the Town received an official request from the Division of Water
Quality (DWQ) to begin evaluating alternatives for a plant expansion. In conjunction
with this ARCADIS study, another consultant is working with the Town of
Richlands to help identify sources of infiltration and inflow (I/I) in the collection
system. The final report for the WWTP capacity analysis and expansion alternatives
investigation will include the results from the I/I study as well as the feasibility of
equalization.
The Town of Richlands is a member of ONWASA, a joint utility consisting of
Onslow County, the Marine Corps Base Camp Lejeune (MCBCL), and the towns of
Richlands, Swansboro, Holly Ridge, and North Topsail Beach. The goal of
ONWASA is to implement a plan to provide water and wastewater services to meet
countywide needs through year 2030 and beyond. ARCADIS assisted ONWASA in
the development of a Resources Management Plan (January 2003) that identified
areas of growth and infrastructure needs in Onslow County. The County is growing
at a modest rate of 2 to 3 percent per year. Wastewater flow projections for the Town
of Richlands and nearby service areas are detailed on the following table.

Dear Mr. Withehead:
The Division evaluated your request for a permit modification and is hereby providing a
modified supplement to permit cover sheet. Please replace the supplement to permit cover
sheet in your existing permit with the enclosed page. The wastewater treatment facility
description was modified to list the tertiary filters as an optional treatment component. As
explained by the town, the continuous operation of the filters is not necessary to meet the
effluent limitations and it causes operational difficulties to continue to operate in a constant
mode.
If you have any questions concerning the permit or the other requirements for your
facility, please call Teresa Rodriguez at [phone], extension 553.

Dear Mr. Powell:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended).
Note that this permit's limits and monitoring frequencies take effect on August 1, 2002. The limits and
monitoring frequencies in your existing permit will remain in effect until that date. This final permit includes one
major change from the draft permit sent to you on April 17, 2002:
➢ Monitoring frequencies for most parameters have changed due to the re -rating of your facility from
Class III to Class Il. This change was based upon the new rating issued by the NC DENR Wilmington
Regional Office.
➢ Limits for BOD and Fecal Coliform have been changed from Daily Maximum values to Weekly
Average values. This change was based upon Federal permitting requirements for publicly -owned
treatment works.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to
you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of
this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North
Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain
other permits which may be required by the Division of Water Quality or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Charles Weaver at telephone number (919)

Permits & Engineering Comments:
This is a permit renewal for a municipal wastewater treatment system with dechlorination and
phosphorus removal. Recent upgrades to the facility not only increased the plant's capacity but also
allowed for advanted treatment to meet permitted limits. The facility has only one industrial user, a
groundwater remediation system discharging "clean" water to the plant. This has been permitted by
DWQ, and no LTMP is necessary. P&E recommends renewal with existing limits and changes noted
above.

2. Date of Investigation: January 29, 1992
3. Report Prepared by: Edward Beck
4. Persons Contacted and Telephone Number:
Jimmy Powell, ORC
[phone]
5. Directions to Site: In Richlands, travel north on NCSR 1003
approximately 0.5 mile to a dirt road to the right. The
treatment facility is located at the end of the dirt road.
6. Discharge Point: Latitude: 340 54' 12"
Longitude: 770 32' 15"
USGS Quad Sheet: Richlands
7. Size: The site is approximately 10 acres although much of
it is wetland and has been used as a landfill.
8. Topography: The site is flat at elevation approximately 26
feet msl.
9. Location of nearest dwelling: no dwellings within 1000
feet.

PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. Description of existing treatment facility: The existing
0.21 MGD facility consists of an influent pump station,
continuous recording flow meter, a contact stabilization
treatment plant, effluent chlorination.
2. Description of proposed treatment facility: The proposed
facility is to consist of a headworks facility with
mechanical screens and a grit chamber with grit removal
pumps, an influent pump station, an oxidation ditch with
disk aerators and magnesium hydroxide feed, dual secondary
clarifiers with ferric chloride feed, an aerobic sludge
digester, an aerated sludge holding basin, dual traveling
bridge tertiary filters, a chlorine contact basin using gas
chlorine, a post aeration basin with floating aerators and
SO2 feed for dechlorination...
3. Sludge handling and disposal scheme: Dewatered sludge is
currently being taken to the Onslow County Landfill. The
Town will probably employ a contractor to land apply sludge
in the future. Prior to land application, the federal
guidelines for Processes to Significantly Reduce Pathogens
must be met. These guidelines require that sludge be
aerobically digested at residence times ranging from 60 days
at 15 C to 40 days at 20 C, with a volatile solids reduction
of at least 38%. If the proposed sludge digestion and
holding facilities are not capable of meeting these
criteria, then additional treatment such as lime
stabilization may be required.
4. Treatment plant classification: Class III
5. SIC Code: 4952
Wastewater Code: 01
Main Treatment Unit Code: 106 1
PART III - EVALUATION AND RECOMMENDATIONS
The basic design of the proposed facility should serve the
small town well and should be capable of meeting the effluent
limits contained in the permit. The chlorine contact chamber has
less than 30 minutes of contact time. This may be acceptable
since the high degree of treatment should produce an effluent
with very low suspended solids.
It is recommended that standby power be required for the
treatment facility and the influent pump station. This will
prevent overflows and allow wastewater to flow through the plant
and receive treatment prior to discharge to nutrient sensitive
receiving waters during power outages.

It is recommended that Authorization to Construct be issued
for the project.

Subject: AT Justification/Checklist for Richlands 201 Facilities Plan
Projects No. C370578-01
Permit No. NPDES NC0023230
Onslow County
The permit limits given to the Richlands WWTP were not the result of a modeling
analysis. Therefore, an AT checklist is not included in this response. In
place of a checklist, the following summary is given to justify the limits for
the Town of Richlands expansion from 0.21 MGD to 0.25 MGD.
Introduction
The Town of Richlands WWTP discharges to Squires Run which is a tributary to the
New River in the White Oak River Basin. The outfall is located approximately
2.4 miles above the mouth of Squires Run. The New River and its tributaries are
classified nutrient sensitive waters (NSW). The River has been studied
intensely for several years and cases of excessive growth of aquatic
macrophytes, fish kills, algal blooms, oxygen depletion, and chlorophyll -a
violations have been documented on a consistent basis since 1985. Since the
late 1980's new discharges and expansions of existing facilities beyond what has
been authorized have been denied.
Summary of Wasteload Analysis
The wasteload allocation (WLA) for permit renewal and modification for the Town
of Richlands was completed by the Instream Assessment Unit in March, 1992. The
evaluation included a modeling analysis which showed violations of the dissolved
oxygen DO standard (below 5 mg/1) at advanced tertiary limits (5 mg/l BODS and 1
mg/l NH3N). The model results did not reflect the instream self -monitoring data
collected from the facility which showed the DO standard of 5 mg/l protected.
As part of the review for permit renewal/expansion, a staff report was sent to
Technical Support from the Wilmington Regional Office with information
concerning the facility's inability to comply with both their flow limit (i.e.
they have been experiencing inflow/infiltration problems) and a new total
phosphorus limit (required for all facilities greater than 0.05 mgd to meet by
January 1992)

Information provided on the staff report stated that the facility would not be
able to comply with the new phosphorus limit or get the inflow/infiltration
problems taken care of unless they were allowed to accept the new flow and
receive the money to build a new wastewater treatment facility and perform some
renovations of the existing sewer collection system. Therefore, the decision to
issue limits of BOD5=5 mg/l and NH3N=2 mg/1 was based on best professional
judgement considering the impacts already incurred in the basin and the
necessity to improve treatment at the plant.

SUBJECT: Town of Richlands WW'IP
201 Facilities Plan
NC0023230
Technical Support has received the Town of Richlands 201 Facilities Plan for its expansion
of the wastewater treatment plant from 0.21 MGD to 0.25 MGD. The Town of Richlands
discharge is located in the New River Basin. Due to poor water quality conditions, new
discharges and expansions of existing facilities have been restricted in this basin. The
portion of the basin below Richland's discharge has a severe aquatic macrophyte problem.
All alternatives to discharge should be carefully evaluated, especially land application.
Other facilities in the basin have been denied expansion or targeted for removal.
If no other alternative to discharge can be found, the limitations presented on page 3 of the
Facilities Plan are appropriate for the Richlands WWTP. As specified in the Plan, a total
phosphorus limit and a total residual chlorine limit would have to be met upon expansion to
0.25 MGD. Extensive instream monitoring is also required for this discharge. Should any
classified industrial waste be added, a pretreatment evaluation may be necessary, and
metals limits may be implemented based on the outcome of the evaluation. The Town of
Richlands has not submitted any information to indicate that an industry may be added.

AMENDMENT TO
TOWN OF RICHLANDS
201 FACILITIES PLAN
MAY 25, 1992
I. OVERVIEW
F. T. Green & Associates, P. A. has been retained by the Town
of Richlands for the purpose of re-evaluating alternative
wastewater disposal methods for the town. The report is
intended to provide a comprehensive, cost effective, socially
acceptable and environmentally sound examination of future
wastewater treatment needs for the town.
A. Summary
Over the past few years the town's previous consulting
engineer has evaluated and recommended land application
as the method of ultimate wastewater treatment and
disposal. However, these studies were based on some
rather significant flow inaccuracies and further
evaluation of alternative disposal methods has been
required.
Further evaluation of the land disposal alternative has
been addressed incorporating the revised flow
projections. As well as a plan to upgrade the existing
secondary treatment facility.
A brief description of the two (2) alternatives is:
Land Application. Construct extensions to the town's
interceptor sewer system which include both gravity and
pumping components designed to deliver the projected
flows to the treatment site located approximately one-
half mile northeast of the town.
The land application disposal system would consist of a
single treatment and storage lagoon, post chlorination
facilities, pumping facilities, manual solid set spray
irrigation system (5 zones), site access and fencing and
104 acres of land - 81 acres wet, 13 acres buffer and 10
acres for lagoon and other miscellaneous requirements.

��:+ Upgrade Existing Facility. Construct a tertiary
' wastewater treatment facility at the location of the
present secondary plant. This should be accomplished by
Y 2� 19g2 utilizing as much as practical any existing structure and
treatment component that can be cost effectively upgraded
2051g1-,wasto handle the projected increased flows.
�na�ctl4o Gr�n1s

The proposed system will consist of influent flow
screening and grit removal; influent pump modifications;
dual concentric oxidation ditch, extended aeration
treatment system; dual secondary clarifiers; dual
tertiary filters; chlorination/de-chlorination units; and
post aeration. All necessary flow directing and sludge
recirculation system will be incorporated into the
design.
The existing masonry contact stabilization treatment
facility will be converted to an aerobic digester and
aerated sludge holding units.
The existing discharge into Squires Run will not be
altered and only land currently owned by the town and
currently in use at the existing facility will be
affected by this project.
B. Recommendations
Based on the conclusion developed from the evaluations of
the two (2) alternatives described above it is
recommended that the Town of Richlands construct the
necessary modifications to the existing secondary
treatment plant that will enable the proposed facility to
treat 250,000 gallons per day and meet the more stringent
limits assigned to the plant and to continue a discharge
into Squires Run at its present location. Total cost of
this project including all system rehabilitation,
collection and interceptor sewers, and treatment works is
estimated to be $2,333,975.
Based on total project cost, land availability, resulting
environmental impacts and public acceptance, this plan
appears to be the best choice for ultimate wastewater
disposal for the Town of Richlands. It is certain to
enable them to meet their need for the future as well as
improve the revised water quality standards of the
receiving stream, Squires Run.
II. BACKGROUND
A. Water Quality Objectives
The discharge from the proposed Richlands wastewater
treatment facility is into receiving waters designated as
Mills Swamp (Squires Run) in the White Oak River Basin.
Mills Swamp is classified as Class "C" waters.
2

10
The town presently has an NPDES Permit (No. NC0023230)
for the discharge of 210,000 gallons per day. Summer
monthly limits are 10 mg/l - BOD51 30 mg/l -SS, and 2 j
mg/1 - NH3 (N) .
Winter limits are 15 mg/1 - BOD5, 30 mg/1 - SS and 5 mg/l
- NH3 (N) .
There is a quarterly average limit on phosphorus of 2'
mg/1 - summer and winter and the fecal coliform limit is
1000/100 ml year round.,
An application for the 250,000 gpd facility has been
submitted and projected wasteload allocations are
forthcoming. It is anticipated that the new effluent
limits will be the following:
BODS
TSS
NH3-N
D.O.
Fecal Coliform
Phosphorus
Residual Chlorine
5.0 mg/1
30 mg/l
2.0 mg/1
6.0 mg/l
200/100 ml
2.0 mg/l
20.0 µg/l
Should this facility be constructed an immediate
improvement of the local surface waters will be realized
in terms of aesthetics and fish and wildlife growth.
Description of Existing Facilities
The Town of Richlands currently operates a wastewater
collection interceptor and treatment facilities that
provides service to approximately 490 users on the
system. The collection and interceptor system consists
of approximately 36,500 feet of 6-inch through 12-inch
diameter sewers and four (4) pump stations.
The treatment facility consists of an influent lift
station, aeration basin, re -aeration basin, one
clarifier, a chlorine contact chamber, aerobic sludge
digester and sludge drying beds.

There are currently 521 total sewer connections into the
Richlands system of which 491 are in town customers and
30 are out of town customers. Based on the 1992
population of Richlands being 1100 the number of persons
per connection is 2.25 (1100/491=2.24). Therefore the
average per capita daily flow can be computed as follows:
158,000 gal/day = 135 gal/per/day
521 users x 2.25 persons/user

IV. SERVICE AREA DESCRIPTION
The Town of Richlands is located twelve (12) miles northwest
of Jacksonville in Onslow County. Current population is
approximately 1150 persons.
The town presently operates a wastewater collecting and
treatment system which serves the vast majority of all town
residents and there are currently plans for sewer extensions
into the unsewered, incorporated areas as well as to some
densely populated locations adjacent to the town.
V. ALTERNATIVES FOR TREATMENT
A small community such as Richlands which is remote to larger
municipalities that possess mammoth wastewater treatment
complexes with surplus capacities has very few options for
wastewater disposal. The following are the most viable of the
alternatives available to the town:
• Construct a 0.25 MGD land application - no discharge -
system on a site having suitable hydrogeologic
characteristics that will sufficiently treat and absorb
a continuous application of wastewater design flows
throughout a 20-year planning period.
• Construct a 0.25 MGD tertiary treatment facility at or
adjacent to the existing contact stabilization treatment
plant and maintain a discharge into the present receiving
stream.
• No Action

PROPOSED 0.25 MGD
TERTIARY TREATMENT FACILITY
RICHLANDS, N.C.
94k

VI. DESIGN CRITERIA
Design criteria, schematic of proposed treatment facilities,
and calculations for the selected alternative have been
prepared and are included.
VII. SELECTED TREATMENT ALTERNATIVE
Based on a comparison of environmental, social, and economical
impacts of the various alternatives presented the 0.25 MGD
tertiary treatment and disposal facility appears to be the
most cost effective plan for the Town of Richlands to pursue.
This alternative will allow the Town to meet expected growth
in the area and improve the waters of the receiving stream.
Development cost for the treatment facilities will be
$1,921,975.
VIII.ENVIRONMENTAL ASSESSMENT (Selected Plant)
A. Area Impact
All portions of this project will be constructed in areas
currently owned by the Town of Richlands or in existing
easements and rights of way. The wastewater treatment
facility expansion will be constructed on the existing
4.25 acre site and will not require the acquisition of
additional property. Adjacent land uses include
agricultural and fields and wetlands.
The effect of the project on commercial and residential
areas will be positive as additional capacity will be
provided in the Town sewer system for expansion.
The project should have no effect on agricultural
resources since all work will be done in existing rights
of way.
The effect on transportation will be some minor
inconveniences to the traveling public during
construction along the rights of way of the various
streets. However, any disruption would be temporary and
should not effect the transportation facilities
significantly.
The effect on the school will be beneficial by allowing
for expansion.
11

The effect on adjacent wetlands and the floodplain will
be minimized during construction by obtaining all
appropriate permits from the applicable regulatory
agencies and making compliance with all requirements and
regulations a condition of the construction contracts.
B. Air Quality
1. The project will not result in any significant air
quality emissions and should have a positive effect
on the existing ambient air quality of the area.
2. Some minor odors may occur in the sludge handling
process at the wastewater treatment facility.
However, these odors should be an improvement of
the current situation since the existing sludge
drying beds will be taken out of service.
3. There are no known topographical or meteorological
conditions that may hinder the dispersal of air
emissions in the area.
4. All applicable Federal and State air quality
regulations will be complied with during
construction and after completion of the project.
C. Water Quality
1. The discharge from the existing wastewater
treatment plant flows into Mills Swamp a Class C
stream in the White Oak River Basin. The treatment
plant is struggling to maintain compliance with
permit limits. The proposed improvements to the
facility will provide improved treatment and added
capacity. The project will cause a major
improvement in the water quality of the area.
2. Potable water will be supplied for the project by
the Town of Richlands. The project will use only a
small amount of water for rest room and laboratory
facilities.
3. The influent flow to the treatment facility is
domestic strength wastewater and possesses
generally the following characteristics:
BOD5
190 mg/l
TSS
199 mg/l
NH3-N
0.25 mg/1
P
4 mg/1
12

`J
FAR
E.
Prior to discharge into the environment the
effluent will be treated to meet the following
limits:
BOD5
TSS
NH3-N
D.O.
Fecal Coliform
Phosphorus
Residual Chlorine
5.0 mg/1
30 mg/1
2.0 mg/l
6.0 mg/1
200/100 ml
2.0 mg/l
20.0 µg/l
4. The treatment system will be a conventional
activated sludge type system with a capacity of
250,000 gallons per day. The system will also
include tertiary filters and will be more than
adequate to provide the level of treatment that
will be necessary to meet the above effluent
limits. The receiving waters are not used for
recreational purposes.
5. The treatment system will be more that adequate and
will not be overloaded.
6. Surface runoff will be handled by a storm drainage
system with controlled outlets.
Solid Waste Management
1. No significant solid waste production will occur as
a result of the project.
2. Any small amount of solid waste will be taken to
the landfill with other garbage by the Town of
Richlands.
3. Recycling or resource recovery programs will not be
used.
Transportation
1. The project area is served by the system of paved
streets in the Town of Richlands.
2. No new transportation patterns will result from
this project.
3. Not applicable to this project.
4. Not applicable to this project.

J.
Noise
1. The only major source of noise at the project site
will be the existing blowers for the diffused
aeration system. However, a muffler/silencer
system will be provided to keep all noises to a
minimum.
2. The only adjacent land use that may be slightly
affected is currently an agricultural area.
Historic/Archeological Properties
1. No historic or archeological resources will be
affected by this project since all construction
will occur in previously disturbed areas.
2. No historical/archeological survey has been
conducted for the project area.
Wildlife and Endangered Species
1. There are no known wildlife resources located in
the project area or immediate vicinity.
2. No known endangered or threatened species or
critical habitat have been identified in the
project area or immediate vicinity, to the best of
our knowledge.
Energy
1. The project facilities and primary beneficiaries
have electrical service from Carolina Power & Light
Company.
2. The energy requirements will increase for the new
facility but it will not add significantly to the
load placed on the power company.
Construction
Mitigative measures to reduce noise levels might include
requiring muffler systems on heavy machinery and
scheduling work accordingly where noise could affect
Populated areas. Soil erosion and siltation could be
14

L.
M.
controlled by implementing sedimentation and erosion
control measures approved by local and state agencies,
i.e, silt fence, check dams, and seeding and mulching.
Toxic Substances
1. No toxic substances will be utilized by project
facilities or beneficiaries.
2. Not applicable to this project.
Public Reaction
1. There has been no public objection to the project.
2. A public hearing has not been held for the project.
3. Public notice through the newspaper will be
required during the permitting process for the
project.
Mitigation Measures
In order to reduce the adverse environmental impacts
associated with the project, the following mitigative
measures will be incorporated into the scope of the work:
(a) limit land disturbing activities before restoration
and landscaping to 1 mile or 30 days, whichever is less;
(b) install bored pipe encasements wherever practical to
reduce accumulation of mud and/or dust along roadways and
adjoining properties; (c) specify construction schedules
to conform with normal activities of the area affected;
(d) protect all disturbed areas from erosion by
installing appropriate erosion and sedimentation control
devices as approved by local and state agencies; (e)
monitor noise levels resulting from the construction
equipment to insure that a nuisance is not created as a
result of the contractor's operations; (f) provide
adequate and orderly traffic control throughout the
entire project under a plan approved by DOT; (g) remove
all construction debris and residue immediately upon
completion of the work.
15

N. Permits
1. The following are the permits required prior to any
construction commencing on this project:
NPDES Permit - N. C. Department of
Environment, Health and Natural Resources -
Water Quality
Soil and Erosion Control Plan - N. C.
Department of Environment, Health and Natural
Resources - Land Quality
Encroachment Agreement - N. C. Department of
Transportation
CAMA Permit - N. C. Division of Coastal
Management
2. The respective permits will be requested during the
design of the proposed project.
IX. OTHER SYSTEM IMPROVEMENTS
A. Sewer System Rehabilitation
Due to the age and materials of construction of the
majority of the town's ± 7 miles of sanitary sewers a
substantial quantity of infiltration and inflow enters
the sewer system during prolonged wet periods and during
excessive rainfalls. Of particular concern is the
interceptor sewer adjacent to the creek leading to the
treatment plant and the old collection sewers within
central business district of town. Extensive smoke
testing and random flow monitoring have identified
numerous point sources of extraneous flow within these
areas.
One other area of major concern is a newly developed area
west of highways 24 and 258.
The shaded areas delineated on the following map of the
town's sewer system identify the location of the proposed
internal television inspection.

Upon completion of this rehabilitation work it is
estimated that approximately 30% of the
infiltration can be eliminated and 80% - 90% of the
inflow will be removed from the system.
(2) Present Worth of Rehabilitation
Should the sewer system rehabilitation work not be
performed, a wastewater treatment facility with
approximately 325,000 GPD capacity must be
constructed.
