MEMORANDUM
TO: Dave Goodrich
THRU: Ruth Swanek ec3
Carla Sanderson
FROM: Jacquelyn M. Nowell
SUBJECT: Response to Request from Lenoir -Gunpowder Creek WWTP for Reduction
in Instream Nutrient Monitoring
NPDES Permit No. NC0023736
Caldwell County
The Instream Assessment Unit has reviewed the May 7, 1997 letter from the subject
facility requesting a reduction in monitoring frequency for the following parameters: total
phosphorus, total nitrogen, chlorophyll a (pheophytin a corrected). The Gunpowder Creek
plant currently has a permitted frequency of weekly monitoring during the months of May
through September only and have requested a reduction to monthly monitoring. A review
of the most recent WLA completed in March, 1995 indicated that twice per month
monitoring for these parameters had been recommended by the Instream Assessment Unit.
Instream data for TP and TN sampled at all three downstream sites nearly always
exceeded state criterias of 0.1 and 1.0 mg/I, respectively. Chlorophyll a data sampled at the
third downstream station in the Old Millpond from May 1994 to September 1996 showed
monthly average values ranging from 7.0 to 38.17 mg/m3 (µg/1). However maximum
daily values during this same period ranged from 20.2 to 53.5 µg/l. During this time, three
daily values exceeded our state standard for chlorophyll a of 40 ug/l. DWQ staff reported
in 1994 that algal blooms have been known to occur in waters where chl a is 20-25 µg/l.
This data seems to indicate the potential for eutrophication problems in this millpond.
Based on this data review, IAU cannot concur with a reduction to once per month
for the nutrient parameters. A sample taken only once per month may not be truly
representative of circumstances within the millpond. Weekly sampling will give a truer
picture but may be too costly for the facility. IAU recommends that the initial
recommendation of twice per month for instream monitoring of nutrients be
reinstated. With chorophyll a values above 40 µg/1 being reported, this segment of
Gunpowder Creek should continue to be monitored closely.
If there are additional questions concerning this issue, please contact me.

Subject: Speculative Limits for Caldwell Co. Dischargers
Dear Mr. Childers:
An analysis for speculative effluent limits for the expansion of several facilities in
Caldwell County has been completed by the staff of the Instream Assessment Unit. These
limits were requested in lieu of an area -wide 201 Facilities Plan Amendment for the US 321
Condor from Lake Hickory to Lenoir. Speculative limits were prepared for wastewater
treatment plants for the Lenoir - Lower Creek and Gunpowder Creek facilities,•Granite
Falls WWII' and a proposed regional WWTP downstream of the existing Granite Falls
plant.
Please be advised that response to this request does not guarantee that the Division
willl issue NPDES permits to discharge treated wastewater into these receiving waters. It
should be noted that the preparation of an environtnental assessment (EA) by the applicant
will be required in the following cases: 1) a new facility involving an expenditure of public
funds or use of public (state) lands and having a design capacity of 0.5 MGD or greater and
2) a facility proposing an expansion of 0.5 MGD or greater, or exceeding one-third of the
7Q10 of the receiving stream.
DWQ will not accept a permit application for a project requiring an EA until the
document has been approved by the Department of Environment, Health and Natural
Resources and a Finding of No Significant Impact (FONSI) has been sent to the State
Clearinghouse for review and comment. The EA should contain a clear justification for the
proposed facility and an analysis of potential alternatives which should include a thorough
evaluation of non -discharge alternatives.
In addition, an EA should show how water reuse, conservation, and
inilow/infiltration reductions have been considered. Nundiseharl4e alternatives, such as
spray irrigation, water conservation, inflow and infiltration reduction or connection to a
regional treatment and disposal system, are considered to be environmentally preferable to a
surface >,vater discharge. In accordance with the North Carolina General Statutes, the
practicable waste treattent and disposal alternative with the least adverse impact on the
environment. is required to he implemented. It the EA demonstrates that the project may
result in a significant icant adverse al loct on the Cluality of till '.'ttvir&nrilent, an Environmental
Impact Statement (1:15) \yu.:.J be required. Michelle Suverkruhhe ut the Water Quality
Planning Branch can provi ie further information regarding the requirements of the N.C.
Environmental Policy .Act.

In order to receive final permit limits, a formal application will have to be submitted
to the Division's Permits and Engineering Unit. Per North Carolina's anti -degradation
policy (15A NCAC 2B.0201 (c)(1)), each application for an NPDES permit or NPDES
permit expansion to discharge treated waste will require documentation of an effort to
consider non -discharge alternatives pursuant to North Carolina Regulation 15A NCAC
2H.0105 (c)(2).
Based on available information, the tentative limits for conventional constituents for
the Lenoir - Lower Creel: WWTP at the. expansion flow of 6 MGD are:
Summer Winter
BOD5 (mg/1) 22 30
NH3-N (mg/1) 2 4.6
TSS (mg/1) 30 30
Dissolved Oxygen (mg/1) 5 . nr
Fecal Coliform (#/1(X)ml) 200 200
pH (SU) 6-9 6-9
Chlorine (l.t { /I) 28 28
*rir - no requirement
The instream waste concentration at 6.0 MGD is 44r/0. A chronic toxicity testing
requirement with quarterly monitoring will remain a condition of the NPDES permit. A
complete evaluation of limits and monitoring requirements for metals and other toxicants
will be addressed for all the expansion !lows at the time of formal permit application.
The tentative limits for conventional constituents for the Lenoir - Gunpowder Creek
WWTP at the expansion Clow of 3.2 MGD are:
Summer« inter
BOD5 (mg/1) 22 3()
NH3-N (mg/1) 2 4
TSS (mg/1) 30 30
Dissolved Oxygen (mg/I) 5 nr
Fecal Coliform (#/I00hn1) 200 200
pH (SU) 6-9 6-9
Chlorine (l.tg/l) 26 26
The instream waste concentration at 3.2 MGD is 63%. A chronic toxicity testing
requirement with quarterly monitoring will remain -a condition of the NPDES permit.
Instream monitoring for the parameters, temperature, dissolved oxygen, and conductivity,
wIII still be required. In addition, it is recommended that inStream nutrient monitoring. for
total nitrogen, total phosphorus, and chlorophyll a, he continued during the months of May
through September.

Letter to Mr. Childers

The tentative limits for conventional constituents at the Granite Falls WWTP at the
two proposed flows are as follows:
Summer Winter
Wasteliow (MGD) 1.9 1.9
BOD5 (mg/1) 11..8 18.8
NH3-N (mg/I) 2.9 7.4
TSS (mg/1) 30 30

Dissolved Oxygen (mg/1) 5 nr
Fecal Coliform (#/100m1) 200 200
pH H (SU) 6-9 6-9
Chlorine (pan) 28 28
The instream waste concentrations at 1.9 and 2.7 MGD are 29% and 36%,
respectively. A chronic toxicity testing requirement with quarterly monitoring will remain a
condition of the NPDES permit.
The final speculative scenario was a proposed regional facility with design Bows of
3 or 6 MGD, that would discharge near the mouth of Gunpowder Creek.iust before its
confluence with Lake Hickory. Information provided to DWQ indicated That this regional
facility would allow both the Gunpowder Creek and Granite Falls WWTPs to go off-line
and connect to this plant. Because there is very little slope and the receiving stream is a
cove like area, this discharge at the mouth of Gunpowder Creek would be considered a
direct discharge to Lake Hickory. It is recommended that this proposed facility be
designed to meet advanced secondary limits for conventional constituents. For planning
purposed, it recommended that the plant be designed to meet limits of between 15 to 20
mJl BODS and 2 to 6 mg/1 NH3-N. In addition, tentative limits for non oxygen
consumin2 wastes are:
DO (mg/I) 5
TSS (mg/l) 30
Fecal Coliform (4 I00m1) 200
pH (SU) 6-9
Chlorine (t.tgil) 28
CUiiently, the US Geological Survey, the Western Piedmont Council of
Government (WPC()G) and DWQ are conducting a water quality study to estimate the
assimilative capacity of Lake Hickory for oxygen consuming wastes. Since the study is
still ongoing, no definitive recommendations have been presented. Until that study is
completed and \vatcr quality modeling results a:rc. finalized, the technical Support Branch

Letter to Mr. Childers
- page 4-
recommends that the proposed facility be designed to meet advanced secondary limits with
sufficient flexibility so as to he able to meet BOD5 limits and NH3-N limits in the ranges
described above.
The BOD5 and NH3 limits were recommended usirlg DWQ's Best Professional
Judgment (BPJ) in an effort to help reduce the impact of point sources discharging directly
into the major lakes in the Catawba River Basin.* With existing stages of eutrophication and
documented water quality problems in Lakes Wylie, Rhodhiss, Hickory and other tributary
arms above lakes, DEM does not recommend continuing with the minimum level of
wastewater treatment for direct discharges to lakes. Therefore, BPJ limits will be applied
to all new and expanding discharges to the Catawba chain lakes.
Nutrient loading can cause water quality problems in lakes. For the expanding
WWTPs at Lenoir -Gunpowder Creek, Granite Falls and the proposed Gunpowder Creek
discharger• near the mouth, It is recommended that the treatment plants be designed so that
they can be easily upgraded for nutrient removal. This would he a proactive measure, in
the event that water quality studies show that nutrient limits, particularly for total
phosphorus, are necessary in the future.
It should be noted that the summer and winter NH3-N limits recommended for all
these plants are based on protecting the receiving streams against instream toxicity. North
Carolina is evaluating all .NPDES dischargers for ammonia toxicity following the
Environmental Protection Agency (EPA) guidance to protect the waters for an instream
criteria of 1. mo/1 in the summer and 1.8 mg/1 in the winter, under 7Q10 flow conditions.
The Division of Water Quality (DWQ) is requiring chlorine limits and
dechlorination for all new or expanding dischargers proposing the use of chlorine for
disinfection. The process of ch1olination/dechloi nation or an alternate form of
disinfection, such as ultraviolet radiatioIl, should allow the facility to comply with the total
residual chlorine limits recommended in the above scenarios.
The request did not indicate whether any of the expansion wastewater would have
any industrial constituency, therefore this aspect could not be evaluated. If there is any
industrial flow. there is the possibility that effluent limitations or monitoring for toxicants
or metals could he added to the permits upon further evaluation.
DWQ is currently on its second round of implementation of a basinwide water
quality nanagcnienl initiative for the Catawba River Basin. Our next installment of the
Catawba River Basin plan is scheduled for publication in the year 2000 . We Mil attempt
to further address all sources of point and nonpoint pollutants where deemed necessary to
protect or restore water quality standards. In addressing interaction of sources, wasteioad
allocations may he affected. Those facilities that already have committed to high levels of
treatment technology are least likely to be affected.

Letter to Mr. Childers
- page, 5-
Final NPDES effluent limitations will be determined after a formal permit
application has been submitted to the Division. If there are any additional questions
concerning this matter, please feel free to contact Ruth Swanek (ext. 503) or Jackie Nowell
(ext. 512), of my staff at (91.9) 733-5083.

Re: Speculative Discharge Permit Limits
Caldwell County
Dear Don:
We are in the process of preparing an area -wide 201 Facilities Plan
Amendment for an area of Caldwell County generally described as the US
321 Corridor from Lake Hickory to Lenoir. It includes the municipalities of
Lenoir, Cajah's Mountain, Hudson, Sawmills and Granite Falls.
We have performed a preliminary screening of alternatives, and require
speculative discharge permit limitations for the following locations and
capacities:
Lenoir Lower Creek WWTP
Lenoir Gunpowder Creek WWTP
Granite Falls WWTP
New WWTP Discharging Downstream
of Existing Granite Falls WWTP
nearer or at Lake Hickory
6.0 MGD
3.2 MGD
1.9 MGD (2.7 MGD)
3.0 MGD (6.0 MGD)
With regard to the option of siting a new discharge location, we are open to
suggestion and discussion as to the competing advantages and
disadvantages of locating the discharge nearer or at the Lake versus further
upstream on Gunpowder Creek.
Please contact me if you have questions of need additional information.
Sincerely,

Facility requesting reduction in instream monitoring for TP, TN, chorophyll a and
pheophytin a from weekly to monthly monitoring. WLA in 3/95 done by F. Keough
recommended twice per month monitoring for nutrients from May to Sept. Previous WLA
in 1992 done by S. Wilson was the first WLA where nutrient montoring was given, twice
per month frequency with same months also. Frequency given as weekly in the permit
issued to Gunpowder WWTP. Haven't been able to determine why the frequency was
changed. 15A NCAC 2B.0500 regulations do not list a specific frequency for nutrient
monitoring for a this class of facility. Three/week frequency for DO, Temp, and fecal if
sampled upstream and downstream for Class IV, domestic sewage dischargers in water
quality limited streams.
Called Gary Francis of ARO, He went for lab inspection, facility complained about
frequency, he told them they could write and request a reduction, But in his mind, he was
just talking and felt they should have talked with regional engineer, Jim Reid. Jim has no
knowledge of the situation, said he would concur with whatever recommendations we
came up with. Told him i would probably recommend original twice per month to give the
Town some relief, but could not recommend monthly monitoring.

Dear Mr. Goodrich:
Upon tallcing with Gary Francies, Asheville office laboratory inspector, it was
suggested that we request a reduction in frequency of testing for our
Gunpowder Creek WWTP facility (NPDES Permit # NC0023736), at
Gunpowder Creek Upstream, Downstream Point 1, Downstream Point 2 and
Downstream Point 3 locations.
The parameters, current frequencies and locations are listed below:

Caldwell Co. Speculative discharges
- Lenoir -Lower Creek WWTP
- Lenoir -Gunpowder Creek WWTP
- Granite Falls WWTP
- Regional Gunpowder Creek or Lake Hickory discharge
JMN
Engineering firm of McKim & Creed has requested several speculative discharge requests
for the above facilities. Expansion requests include:
1) Lenoir -Lower Creek WWTP from 4.08 MGD to 6 MGD (last spec requested in Sept.
1994 for 5 and 7 MGD)
2) Lenoir -Gunpowder Creek WWTP from 2.0 MGD to 3.2 MGD (last spec requested in
1994 for 2 MGD)
3) Granite Falls WWTP from 0.9 MGD to 1.9 or 2.7 MGD (last spec requested in
1995 for 0.9 MGD)
4) Regional Gunpowder Creek or Lake Hickory WWTP discharge of 3 or 6 MGD , located
downstream of the Granite Falls WWTP, nearer or at Lake Hickory
Lenoir -Lower Creek WWTP
Last spec in 1994, @ 5 and 7 MGD. Recommended secondary limits for summer and
winter BOD5 @ 5 MGD, Summer BOD5 limit of 17 mg/1 @ 7 MGD.
Spec BOD5 limits for 6 MGD would probably be less than 30 mg/1 but higher than 17
mg/1. NH3 toxiciity analysis indicates NH3 limits of 2 mg/1 summer and 4.6 mg/1 winter.
DO limit of 5 mg/1 also recommended.
Regional WWTP on Gunpowder Creek @ 3 and 6 MGD, located below
Granite Falls and closer to Lake Hickory or further upstream on
Gunpowder Creek
Conversation with Bevington: Asked whether the USGS report on Lakes Rhodhiss and
Hickory had been completed and whether any recommendations from that report could be
used. Called Mary Jaynes at USGS and said that neither report was out yet. Had
completed a draft of the water quality section. They are still working on the QUAL-WQ2
model for the two lakes. This model is two dimensional and laterally averaged. The Lake
Rhodhiss model is over 50% completed. A report could be out in 6 months. There has
been no progress on the Lake Hickory model. There has been some monitoring of
Gunpowder Creek - DO temp pH, no nutrients. Have been monitoring nutrients in Lower
Creek, also in the Upper Little River and Middle Little River. The model is taking more
time than anticipated. No recommendations yet for dischargers to Lake Hickory.
Bev and I discussed the proposed regional plant and decided that we should probably
consider this facility at the mouth of Gunpowder Creek as a direct discharge going into an
arm of Lake Hickory and recommend that advanced treatment limits would be
necessary. Probably could not give specific limits but give a range of BOD5 and NH3
limits that the facility will have to treat to.

Telecon w/ Sid Riddick of McKim & Creed, engineers for Caldwell Co.
project 1/28/97
Asked about the proposed facility at the mouth of Gunpowder Creek, and whether any
other dischargers would go offline with its completion. He indicated that if this alternative
was adopted, Lenoir- Gunpowder Creek and Granite Falls would go offline. Municipality
of Hudson wasteflow already goes into Gunpowder Plant. they are looking at either
upgrading the two existing plants in capacity and treatment capability or constructing a new
plant that would combine the flows of both. Indicated that the Granite Falls plant would
probably only be able to go up to 1.8 -1.9 MGD for hydraulic capacity and due to lack of
available land would not be able to go up to 2.7 MGD. This scenario could be deleted if not
already done.
Told him that the proposed regional plant at the mouth of Gunpowder would probably,
have to meet advanced treatment with NH3 limits around 2 -4 mg/1 in the summer and
winter. Anticipating some completion or recommendation from the USGS study and
model of Lake Hickory. But study has not been completed as yet.
