Subject: Issuance of NPDES Permit NCO062219
Kings Grant WWTP
Wake County
Dear Mr. Daniel:
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).
This facility discharges in the Neuse River Basin (NRB). All streams in the NRB have
been designated as nutrient sensitive waters (NSW) as a'result of algal bloom problems in
the estuary. The North Carolina Environmental Management Commission recently adopted
rules establishing the Neuse River Basin Nutrient Sensitive Waters Management Strategy for
the reduction of phosphorus and nitrogen inputs. The point source rule (15A NCAC
2B.0234) is intended to reduce total nitrogen (TN) discharges by 30% by 2003. It specifies
that individually permitted wastewater discharges to the NRB with permitted flows less than
0.5 MGD in 1995 shall be allocated a collective annual mass TN load of 155,400
pounds/year. This is equivalent to an allocation in the range of 5 - 10 mg/L TN for each
small discharger. Although -no total nitrogen limits appear in this permit, your facility
may be subject to nitrogen limits in the next permitting cycle. All facilities with
permitted flow greater than or equal to 0.5 MGD are receiving a TN limit in this permit cycle.
The Division recommender that you evaluate the cost of installation for nutrient
removal facilities in the event that a nutrient limit is imposed on your plant. It is also
recommended that alternative discharge options be evaluated such as such as spray
irrigation, subsurface systems, wastewater reuse, or connection to a larger regional system.
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.

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.

A. (3.) TOTAL NITROGEN MONITORING
The Permittee shall calculate the annual mass loading of total nitrogen as the sum of monthly loadings, according to
the following equations:
(1) Monthly Mass Loading (lb/month) = TN x Q x 8.34
where:
TN = the average total nitrogen concentration (mg/L) of the composite samples collected
during the month
Q = the total wastewater flow discharged during the month (MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
(2) Annual Mass Loading (lb/year) = E (Monthly Mass Loadings) for the calendar year
The Permittee shall report the total nitrogen concentration for each sample and the monthly mass loading in the
appropriate monthly self -monitoring report. The annual mass loading of total nitrogen shall be reported in the
December self -monitoring report.
A. (4.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortalit}, to
Ceiiodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Wlnole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of March, June, September & December. Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
If the test procedure performed as the first test of any single quarter results'in a failure or ChV below the permit limit,
then multiple -concentration testing shall be performed at a minimum, in each of the two following months as
described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the
pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621

Permit NCO062219
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days
after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity- monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (A-f) test form indicating the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should dle permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

Dear Ms. Cabe:
In response to your letter of September 9, 1998 regarding the referenced
NPDES permit, we have evaluated the possibilities of connecting the existing
subdivision to public sewer systems.
I spoke with Mr. Ira Fuller, the town manager of Wendell, about connection
into the Town's force main that discharges into the City of Raleigh's
sewerage system. The Town of Wendell owns and maintains this force main,
and they have a standing policy of denying all requests to tap into the
force main.
I also spoke with Mr. Dale Crisp, P.E., of the City of Raleigh's Public
Utilities Department, about the possibility of pumping to the City's Neuse
River WWTP. He indicated that the City's policies would not allow them to
provide service to Kings' Grant because it is outside of the City's ETJ and
perimunicipal planning areas, and this is not an area that could be annexed
by Raleigh in the foreseeable future,
Based on these conversations, we do not believe there is a viable public
sewer alternative for King's Grant, at this time. Therefore, Carolina water
Service proposes to install a U.V. disinfection system on the plant to help
alleviate the toxicity problem. Plans for this system are being forwarded
under separate cover for DWQ's review. Please call if you have any
questions.
Yours very truly,
Diehl & Phillips, P.A.

Current Permit Renewal-?
Carolina Water Service- Kings Grant Subdivision
NPDES Permit No. NC0062219
Wake County
The subject facility is the treatment unit for a residential subdivision with only domestic flow
with a permitted daily flow limit of 0.070 MGD. The facility showed a "FAIL" for chronic
toxicity in June and July 1998. A site visit conducted by Mr. Stafford on September 15, 1998 to
investigate the fails and to pull a chronic bioassay revealed that the de -chlorinator had only one
tablet in it. The residual chlorine in the effluent was 1.5 mg/l and dropped to 0.23 mg/1 when the
operator added additional de -chlorination tablets to the unit. The bioassay result was "PASS" for
that test.
A review of the DMR's for the period September 1997 through August 1998 showed high levels
of residual chlorine in the effluent (See attached DMR's). The RRO requested a biological
assessment of the receiving stream above and below the subject facility. The assessment showed
that King's Grant Subdivision WWTP had a severe affect on the aquatic fauna of the receiving
stream. Comparison of sites above and below the outfall showed a sharp decline in EPT taxa and
a shift to highly tolerant species. (See attached report).
In light of this information, the RRO believes that residual chlorine from the subject facility is
having a negative affect on the receiving stream and that the facility is not diligent in providing
adequate de -chlorination of the effluent. Therefor, the RRO requests that the permit have a
residual chlorine limit placed into the permit during the present permit renewal cycle and that
appropriate daily monitoring be incorporated also.

Biological Monitoring, UT Poplar Creek, above and below the Kings Grant
WWTP, November 1998, Wake County, NPDES NC 0062219
The King's Grant Subdivision discharges domestic waste to an unnamed tributary (UT) of
Poplar Creek. This facility has been failing self -monitoring toxicity tests and inspection by the
Raleigh Regional Office suggested that high chlorine levels may be the cause of toxicity problems.
Inspection by field office personnel (Kirk Stafford) indicated that improper maintenance of
dechlorination equipment may be the cause of high chlorine levels in UT Poplar Creek. Kirk
observed fish above the outfall, but no fish in UT Poplar Creek below the outfall. In order to more
accurately document any impact of the King's Grant WWTP on the stream community, the field
office requested a survey by the Biological Assessment Unit.
METHODS
Benthic macroinvertebrates were collected at all stations using an abbreviated version of the
Division of Water Quality's standard qualitative sampling procedure (Qual 4). This method
includes 4 composite samples: one kick -net samples, one bank sweep, one leafpack sample, and
visual collections from large rocks and logs. The purpose of these collections is to inventory the
aquatic fauna and produce an indication of relative abundance for each taxon. Organisms wercP
classified as Rare (1-2 specimens), Common (3-9 specimens), or Abundant (>10 specimens). c
Several data -analysis summaries (metrics) can be produced from qualitative samples to detect
water quality problems. These metrics are based on the idea that unstressed streams and rivers':'
have many invertebrate taxa and are dominated by intolerant species. Conversely, polluted stre�ns
have fewer numbers of invertebrate taxa and are dominated by tolerant species. The diversity 4?
the invertebrate fauna is evaluated using taxa richness counts; the tolerance of xhe stream c•:
community is evaluated using a biotic index.
EPT taxa richness (EPT S) is one metric used to compare water quality between sites . "EPT"
is an abbreviation for Ephemeroptera + Plecoptera + Trichoptera, insect groups that are generally
intolerant of many kinds of pollution. Higher EPT taxa richness values usually indicate better
water quality. Water quality evaluations also are based on the relative tolerance of the
macroinvertebrate community as summarized by the North Carolina Biotic Index (NCBI). Both
tolerance values for individual species and the final biotic index values have a range of 0-10, with
higher numbers indicating more tolerant species or more polluted conditions. EPT abundance (EPT
N) and total taxa richness also are used to help examine between -site differences in water quality.

SAMPLING SITES (Table 1)
Site #1. UT Poplar Creek above the Kings Grant WWTP. UT Poplar Creek drains the Kings
Grant Subdivision, and most of the catchment is residential land use. This stream is too small
(1 meter wide) to assign a bioclassification. UT Poplar Creek has poor habitat, with rocky
riffles or snags largely absent. Although the stream has not been straightened or channelized,
it has a very uniform sandy substrate. Most of the intolerant species recorded at this site were
found in leaf packs.
Site #2. UT Poplar Creek below the Kings Grant WWTP. This site is at the intersection with
SR 2509. The stream is largely identical to the upstream site, although there is a rocky riffle
just below the discharge resulting from construction rip -rap.

RESULTS AND DISCUSSION
Total taxa richness was low at both sites on UT Poplar Creek (17-24) due to the small size of
this stream and unproductive sand substrate. Five EPT taxa were found at the upstream site, with
three of these being abundant: Allocapnia, Cheumatopsyche, and Diplectrona modesta. Only a
single EPT specimen was recorded at the downstream site, clearly showing a between -site decline
in water quality. The biotic index increased from 5.7 upstream to 7.8 downstream, reflecting a
change from intolerant and facultative species upstream to highly tolerant species downstream.
Tolerant species that were found downstream were organic indicators, especially two chironomids
frequently associated with sewage effluents: Chironomus and Goeldichironomus. An analysis of
21 Chironomus larvae did not show toxicity problems severe enough to cause deformities.

CONCLUSIONS
The King's Grant WWTP was shown to have a severe afect on the aquatic fauna of UT Poplar
Creek. Comparison of sites above and below the outfall showed a sharp decline in EPT taxa and a
shift to highly tolerant species.

sound alternative of the reasonably cost effective alternatives. If the facility is in substantial non-
compliance with the terms and conditions of the NPDES permit or governing rules, regulations or laws,
the permittee shall submit a report in such form and detail as required by the Division evaluating these
alternatives and a plan of action within sixty (60) days of notification by the Division."
The facility has failed the last two chronic toxicity tests, June and July 1998. This may be due
to high levels of chlorine in the effluent. A letter was sent to you July 5, 1990 from Steve Tedder,
Water Quality Section Chief, informing you that an acceptable level of chlorine in your effluent is 17
µg/l. Your average residual chlorine has been 2500 µg/1 over the last year, with a maximum of 4000
µg/l. Kirk Stafford from the Raleigh Regional Office will be performing a site visit on September 16th
to collect a sample for toxicity testing, make a visual inspection of the receiving stream and to help
determine the cause of toxicity and what the facility can do to alleviate the problem.
The files indicate that soils are not suitable for a spray irrigation or subsurface system, but due
to increased availability of public sewer to the area, this option needs to be investigated. An alternatives
analysis must be submitted to and approved by the Division prior to receiving an authorization to
construct to increase discharge flow. Please refer to Section II.A. of the enclosed guidance document.
If you have any questions concerning this information request, please contact me at telephone number
[phone], extension 518.
Sincerely,
Cabe

KINGS GRANT S/D WWTP Permit No. NC0062219
The effluent sample type in the previous permit should have been composite instead of grab for BOD, NH3
TSR, TN and TP. c(l��dc� Laos wt `�. , s �o no �✓w 1
Dechlorination should be required in SUPPLEMENT TO PERMIT COVER as Item #2. �,/,l� �c v� n} )�<<
Historically facility has performed very well in ammonia reduction (due to flows well under design
capacity). However, facility does not have a TRC limit on this 7Q10 = 0 stream. Chlorine and
chloramines are very toxic to aquatic life in these conditions. This facility should get 17 ug/1 for TRC.
Retrofitting dechlor equipment would not a big expense to the utility. Wake Co. position is that all
facilities discharging to intermittent streams should be required to meet
5110, 2/4, with TRC 17 ug/1 limits.

Part III Permit No. NC0062219
E. This permit may be modified, or revoked and reissued to include an effluent limitation on
nutrients for this discharge depending upon the following:
1. The findings of a study by the Division of Environmental Management determine nutrient
control is necessary.
2. Local actions do not successfully reduce the nutrient loading on the receiving waters.
3. The onset of problem conditions in the receiving waters.
F. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure.- Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 90% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit during the months of March, June, September and December. Effluent sampling for
this testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

G. The permittee shall properly connect to an operational publicly owned wastewater collection
system within 180 days of.its availability to the site, if the facility is in noncompliance with its
permit effluent limitations for three consecutive months.

MEMORANDUM
TO: Dave Goodrich srko sly
THROUGH: Matt Matthews r rf\ u l 0 )
FROM: Kristie Robeson V9-1
SUBJECT: Permit Modification
CWS-King's Grant Subdivision
NPDES Permit No. NCO062219
Wake County
By cover letter dated July 30, 1993, the facility was issued NPDES Permit No.
NC0062219 with an effective date of September 1, 1993 and expiration date of May 31,
1998. Upon review of the toxicity language contained in the permit, it was noted that the
permit does not reflect proper sampling requirements for effluent samples contained in the
Division's NCAC 0500 regulations. NCAC Rule .0505 (c)(3)(B) states that "samples of
the influent and effluent of the water pollution control facility or other point sou[ ,�e shall be
composite samples, except as provided in rule .0505 (c)(3)(C)." The M3 page of this
permit which lists parameters to be tested before plant expansion indicates that the permitted
sample type for toxicity will be a grab sample. However, toxicity is not a parameter listed
under Rule .0505 (c)(3)(C). After talking with Steve Bevington in Technical Services, he
felt that toxicity should have been a composite sample and that Permits and Engineering
might want to review some of the other parameters' sample types as well to verify that they
were correct. Based on the facts stated above, this office recommends modification of the
M3 page of the permit before expansion to change the toxicity sampling type from grab to
composite.
I appreciate your assistance to review the recommended changes and undertake any
necessary steps to modify the existing permit. Should you have any questions, please feel
free to contact me at 2136.
