Subject: Issuance of NPDES Permit NC0040266
Knightdale Estates MHP WWTP
Wake County
Dear Mr. Murphrey:
In accordance with your application for permit renewal and after considering public comments on
the draft permit, the Division is forwarding herewith the subject NPDES permit for the Knightdale
Estates Mobile Home Park WWTP. 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, as revised. The permit becomes
effective on August 1, 2004, and expires on February 28, 2008.
The Knightdale Estates permit was one of ten that were the subjects of a public hearing held in
Raleigh on May 29, 2003. The Division heard comments on the permits during the hearing and also
received written comments on some of those permits. We have considered all relevant comments
and are now issuing the final permit, including the following changes since the April 2003 draft:
• Monitoring Requirements. The treatment plant has had a poor compliance record in recent
years, resulting in 16 enforcement actions from 2000 through 2002. In order to encourage more
attention to plant operations, the final permit requires more frequent monitoring than in the
past. The Division cart consider reducing these requirements again when the plant meet its
permit limits for at least one year.
• Wastewater Management Plan. In addition to its poor compliance record, Knightdale Estates
has also experienced a problem common to similar properties, that is, accumulation of
household grease in the collection and treatment systems.
The final permit requires you to (1) evaluate the feasibility of other wastewater disposal
alternatives; and (2) prepare and implement a strategy for informing its tenants of proper use of
its wastewater systems.
• Outfall Signage. The Knightdale Estates treatment plant discharges to a small stream adjacent to
the community. There is some concern that the stream is attractive to nearby residents and their
children as a play area and that there is no indication of the treated wastewater discharge. The
permit requires you to post and maintain a sign identifying your wastewater discharge as such.
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 a demand is made, this permit shall be final and binding.

BACKGROUND
Teresa Rodriguez previously sent out this permit to public notice on December 12, 2002.
Around this time, it became apparent that the Neuse River Foundation was interested in
including this facility as one in a large public hearing planned for the Neuse River. Knightdale
MHP has experienced considerable non-compliance with its NPDES permit over the last three
years — there are records of at least fifteen assessments of civil penalties in the NPDES
correspondence files. Of particular problem seem to be flow, fecal coliform and dissolved
oxygen. In October 2002, Knightdale MHP received an ATC for the construction of an
equalization basin, construction of which should alleviate some of these compliance problems.
As of this drafting, Knightdale MHP still has civil penalties which it is either contesting or has
simply has not paid.
The existing treatment system consists of a manual bar screen, aeration basin, primary and
secondary clarifiers, aerobic digester, chlorinator, chlorine contact chamber and flow meter.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review
This facility discharges to an unnamed tributary to the Neuse River (classified C-NSW). While
not technically listed as impaired, this facility must be compliant with any strategies associated
with the TMDL for the Neuse River Estuary.
The facility monitors for instream temperature, dissolved oxygen and fecal coliform. These data
were reviewed from January 2001-February 2003. Downstream temperatures were slightly
elevated from the upstream levels. Dissolved oxygen downstream of the discharge was
somewhat lower than the upstream values. Instream dissolved oxygen (both upstream and
downstream) was lower than 5.0 mg/L throughout much of the summer of 2002. Levels did not
return consistently above that level until October 2002. Downstream fecal coliform levels were
generally about the same or slightly lower than the upstream values. Plots of all the instream
data analyzed are attached to this document.
Fact Sheet
NPDES NC0040266 Renewal
Page 1

Effluent data was reviewed for the period of September 2000-September 2002. The average flow
was 0.0193 MGD — seven violations of the monthly average flow limit were recorded during this
time period. Average BOD was 6.6 mg/L, average TSS was 8.59 mg/L and average ammonia
was 3.09 mg/L. There were four violations of the ammonia limit during the period of record.
The total nitrogen load reported in 2001 was 985.12 lb./yr.
Correspondence
This facility has consistently had difficulty meeting its limits. In 2001 alone, there were 10
notices of violation issued (with accompanying civil penalties). The majority of these were for
violations of flow, fecal coliform (both monthly average and daily max), and dissolved oxygen.
Failures to monitor and violations of the ammonia and BOD limits have also been recorded. The
facility has contested each of the fourteen civil penalties issued since June 2000 (as per the
correspondence records in Central Files). Thus far, through the appeals process, Knightdale has
gained a reduction in the amount of the civil penalties ten times. They are in the process of
paying off the fines for these ten cases (since December 2002, they have made nine of twelve
scheduled payments); they began paying the fines on these in April 2002 (nearly two years after
the first of the ten civil penalties was issued). There is no record of payment for the remaining
four, all of which are from 2002.
The facility received an Authorization to Construct an equalization tank in October 2002. It is
the Division's hope that this will be constructed in the near future and that this will help the
facility to better comply with the NPDES permit.
PERMITTING STRATEGY
In the previous draft, the following changes were made:
• Daily maximum limits for ammonia were added to the permit as per ammonia policy
implemented in October 2002.
• A daily maximum limit for total residual chlorine (TRC) was added to the permit. A water
quality standard for TRC was adopted by the Environmental Management Commission on
October 2002. All facilities using chlorine for disinfection are subject to a daily maximum
limit. The permit includes a schedule of compliance of 18 months.
The Permittee has expressed an interest in installing UV disinfection, so a footnote will be added
to the TRC limit that states that this limit will only be effective if chlorine is used in disinfection.
Influent monitoring of BOD and TSS was accidentally put in the previous draft and will be
removed.
In addition, language pertaining to Total Nitrogen requirements for all Neuse facilities has been
updated.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies and the permitting strategies in place for the Neuse River
Basin, the following will be incorporated into the permit:
• Daily max ammonia limits
• Daily max TRC limit with footnote
• Updated Neuse language (for Total Nitrogen monitoring)
• Removal of influent BOD and TSS monitoring from previous draft

Dear Sir:
Re: Comments and requested changes to NPDES Draft Permit, Permit No. NC0040266
for the Knightdale Estates Mobile Home Park LP, Wake County, NC.
Y
We are in receipt of the NPDES Draft Permit for the Knightdale Estates Mobile Home Park
WWTP dated December 11, 2002. The Knightdale Estates Mobile Home Park WWTP is aprivately
owned wastewater treatment facility and should not be subject to influent monitoring. These
observations have been communicated with Teresa Rodriguez, who has concurred with this finding.
Also, we are questioning if the daily maximums for ammonia are applicable to this facility, along
with monthly composite sampling for total phosphorous at the plant's effluent.
It is our intention to incorporate ultraviolet disinfection of the plants effluent stream which
to our understanding will void our requirement for bi-weekly monitoring for total residual chlorine.
Respectfully,
Guido J. Carrara, P.E.

Neuse River Basin Public Hearings
Recommendations May 29, 2003
Knightdale Estates MHP
Knightdale Estates WWTP
NC0040266
Facility Description
The Knightdale MHP Limited Partnership owns and operates a 0.025 MGD wastewater treatment
plant in Wake County. The treatment facility consists of a manual bar screen, aeration basin,
primary and secondary clarifiers, aerobic digester, chlorine contact chamber and effluent flow meter.
The plant discharges to an unnamed tributary to the Neuse River, a Class C-NSW water with a
summer 7Q10 flow of 0.19 cfs.
In October 2002, the facility received an ATC for construction of a new equalization basin.
Permit Summary
The facility's permit contains seasonal discharge limits for BOD (27 mg/L summer & 30 mg/L
winter) and NH3-N (4.8 mg/L summer & 21.7 mg/L winter). The draft permit also includes new
daily maximum limits for NH3-N (24 mg/L summer & 35 mg/L winter) and Total Residual Chlorine
(28 ug/L), consistent with recent changes in NPDES permitting policy.
Public Comments
Joe Seigler, Neuse River Foundation:
• Facility has poor compliance record, over $36,000 assessed since 1985. Discharge has
negative impact on low flow receiving stream, and owner does not accept responsibility.
• Recommend:
— educating the permit holder - he must accept responsibility for his actions; must notify
DWQ of ownership and ORC changes
- phase out package plants in low flow streams per Table 4.2 of the 1998 Neuse River
Basinwide Plan; require an EAA with public review
- require facility assessment by 3rd party, with public review
- require more instream monitoring, including nutrients and benthic
- DWQ should scrutinize flows reported in DMRs
— reduce the NH3-N and Total Residual Chlorine limits to protect the stream
DWQ Response and Discussion
Compliance record has been poor in recent years: 16 enforcement actions from 2000-2002 for a total
of $23,550 in penalties. The facility has contested each penalty, and most have been reduced. $1,310
in penalties is still outstanding, and owner is on a payment plan.
Most limits violations have been for flow, fecal coliform, dissolved oxygen, and ammonia, and most
occurred after owner switched ORCs circa 2000. Compliance has been restored for the most part
since the original ORC returned in early 2003.
Construction of the new equalization basin should alleviate some of these compliance problems.

Summary and Recommendations
Knightdale Estates WWTP, NC0040266
We surmised from our site visit that the receiving stream might be a play area for area children. In
2000, we required two permittees to install signage under similar circumstances, and it seems to be
warranted in this case as well.
Increased monitoring frequencies at the facility would help staff evaluate permit compliance and
protection of the receiving stream.
The owner needs to take whatever steps are necessary to ensure continued compliance with permit
requirements. Specific needs could be identified in the permit, which would require submittal of a
Wastewater Management Plan. At a minimum, the Plan should require the permittee to re-evaluate
discharge alternatives, educate tenants about controlling grease, and place a sign at the discharge
point.
Recommended Action(s)
The NPDES Unit should:
1. Include increased monitoring requirements in the final permit until the new owner
demonstrates consistent compliance with the permit limits.
2. Add the following language to the permit to implement the above recommendations:
A. (,) WASTEWATER MANAGEMENT PLAN
1. No later than 180 days after the effective date of this permit, the Permittee shall submit to the
Division a wastewater management plan. The plan shall include, at a minimum, the following
elements:
• Alternatives analysis. Conduct a technical and economic evaluation of wastewater
disposal alternatives, specifically including at least the following alternatives:
— connection to another wastewater collection system, public or private
- conversion to a spray irrigation system
- implementation of a reuse program
- any combination of the above option
The analysis and report shall be consistent with guidance provided by the Division.
• Communications plan. Describe a strategy for informing utility customers of their
potential impacts on treatment system performance and appropriate practices for
minimizing those impacts, including a schedule for implementation of the strategy.
At a minimum, include the following elements:
- oil and grease contributions to the collection and treatment system,
introductory material for new tenants, describing acceptable waste disposal practices,
common problem practices, notification procedures in case of emergency
2. Upon approval by the Division, the plan shall become an enforceable part of this permit.
A. (_.) OUTFALL SIGNAGE
Not later than 120 days after the effective date of this permit, the Permittee shall install and
thereafter maintain permanent signage identifying Outfall 001 as a wastewater discharge point.
Unless otherwise approved in writing by the Director, the signage shall conform to the following
specifications:
1. It shall be located in reasonable proximity to the outfall.
2

Summary and Recommendations
Knightdale Estates WWTP, NC0040266
2. It shall be clearly visible to persons on the adjoining property and in or near the surrounding
waters and, toward that end, shall:
• be two-sided
• be located at least 3 feet above ground level
• at least two feet by two feet (2ft x 2ft) in size
• consist of black letters on a white field; the word "notice" to be at least 3 inches tall and the
remaining words to be at least 21/ inches tall
3. The signage shall contain, at a minimum, the following information:
