SUBJECT:
City of Gastonia, Long Creek
NC0020184, Draft Permit Comments
Gaston County
The following three requests and the general request apply to each permit condition (Al
through C2):
1) Request oil and grease be monitored weekly rather than daily.
Technical Support has no specific comment or concerns.
2) Request downstream sampling at 35 18' 28", 81 05' 57" rather than current locations.
DISAGREE
The downstream sampling site(s) should meet the following conditions:
If the discharge is to Long Creek, the downstream sampling site should be
on Long Creek near the South Fork Catawba. Long Creek at SR 2003 seems an
ideal site for this, but others may be considered.
If the discharge is to the South Fork Catawba, downstream sites should be
established in the Spencer Mountain Dam pool, in the bypass reach, and below the
tailrace. The site below the tailrace should be far enough downstream so that the
water from the tailrace and bypass have mixed. Ideal downstream sampling
locations are the Spencer Mountain Dam pool at the dam, the South Fork Bypass
at SR 2003, and the South Fork 1.5 miles below tailrace at powerlines. The far
dormstream site may be difficult to: reach. If this is the case, a site closer to the
tailrace may be substituted.
3) Reque 4 t samples be collected two times per week rather than current schedule. AGREE
Beause of the multiple downstream discharge points, twice weekly monitoring
should be effective.

General Request. Once discharge is moved to South Fork, effluent monitoring, except
DO and Chlorine, be done at end of WWTP rather than at discharge point. AGREE.
DO monitoring should be done at discharge point.
A.1 (4), A.2 (4). Request chronic toxicity is to be done at 50 rather than 80%. DISAGREE.
Te IWC at the discharge point is 50%. In order to protect water quality, the
chronic toxicity permit condition should remain at 50%.
A.1 (5), A.3 (5). Request that protocol be established for measuring floating solids/foam.
Technical Support has no specific comment or concerns.
A.2 (6). Request TN be changed to 8.0 mg/1 rather than 4 mg/1. AGREE
Winter TN limits should be 8.0 mg/1 for all flow and discharge conditions.
B.4 (4). Request NH3-N be 7 mg/1 rather than 4 mg/1. DISAGREE
The South Fork Catawba River above the Spencer Mountain Dam is a marginally
acceptable site for the discharge of treated wastewater from the Gastonia Long Creek
WWTP. This subject was discussed with Gastonia representatives at several meetings.
The critical impact on water quality is likely to occur after the discharged is moved to the
South Folk but before the facility is upgraded to an advanced tertiary plant. This period is
represented by permit condition B. Modeling of the system predicted that limits of 10
mg/l BOD5 and 4 mg/I NH3-N would protect the DO standard below the discharge. Self
monitoring data collected over the past three years indicate that the facility could meet the
summer NH3-N limit but would might have difficulty meeting a BOD5 limit of 10 mg/1.
Therefore, the existing BOD5 limit was used with a NH3-N limit of 4 mg/1.
BOD5 and NH3-N impacts on DO are proportional, i.e. the NH3-N limit could be
raised if the BOD5 limit was lowered. DEM could meet with Gastonia representatives to
discuss this option.
The remaining requests all deal with issues related to the IWC and 7Q10 values, and are
discussed below.
Flow available for dilution at the South Fork discharge point was calculated as follows:
Flow = 7Q10 flow - upstream Gastonia water supply intake
Fl w = 109 cfs - maximum capacity of withdrawal (42.6 mgd).
Flow = 109 cfs - (1.55 cfs/mgd * 42.6 cfs) = 43 cfs.
G Estonia suggested that the withdrawal should not be considered since the USGS
based its estimates from data downstream of the withdrawal. Technical Support disagrees
�'
with this for two reasons: 1) the USGS estimates 7Q10 statistics using data from the past
2

30 to 50 years. During this period, Gastonia's water withdrawals were well below current
levels. 2) Some of the water withdrawn from the South Fork returns via wastewatei'
discharged to Long Creek, and so is measured at the downstream USGS gage.
The estimate of 43 cfs available for dilution at the South Fork discharge point is a
minimum estimate and may be overly conservative. It is unlikely that the withdrawal with
continue at its maximum for a prolonged period. Also, it is anticipated that the
withdrawal will be replaced with a withdrawal from the Catawba River. Considering these
factors, Technical Support would agree to substitute maximum capacity in the above
equations with some better estimate of current summer demand. Technical Support is
available to meet with Gastonia to discuss an appropriate estimate of summer withdrawal
from the South Fork Catawba river.

Globe Manufacturing
Globe Manufacturing is operating under two Consent Orders.
The City and Globe entered into a Consent Order on August
24, 1993 for Toluene. The facility was in reportable
ortable
noncompliance for two consecutive six months.The
compliance schedule requires full compliance with the permit
limit by September 15, 1994. Incremental developments are
required on December 1, 1993; January 1, 1994; March 1,
1994; and June 1, 1994 with reports due within 30 days of
each deadline. Presently, Globe is punctual with these
requirements.
The Order for BOD and Toxicity was amended on July 14, 1993
due to delays acquiring Authorization to Construct from the
N.C. Division of Environmental Management. Globe has been
punctual with all requirements. The deadline for
implementing the process alternative and beginning
construction was August 15, 1993. A report confirming this
action is due September 14, 1993. Full operational status
is requi ed by September 15, 1994.
The toxicity results supplied in August 1993 for the sample
collected in July 1993 is invalid due to lab error. The
City will require Globe to resample in September. Globe is
also obligated to perform a toxicity test in January 1994.

ATTACHMENT "D"
In the draft permit, the effluent concentration at which there may be
no obser')able inhibition of reproduction or significant mortality has been
established at 22% and 36%.
Based on the City of Gastonia's understanding and calculations, the
concentrations should be at 11% and 23%. These concentrations are based on:
1.
2.
4.
The 7Q10 at the Lowell Station is 119 CFS.
The estimated 7Q10 at the proposed discharge point, Long Creek and
South Fork River, is 109 CFS.
The proposed permitted discharges are 12.48 CFS (8 MGD) and 24.96
CFS (16 MGD) respectively.
Since the official gauging station is measuring the actual flow in
the river below the City's raw water intake and Long Creek
Wastewater Treatment Plant's discharge point, the raw water
withdrawn from the river and the wastewater discharged into the
river should not affect the 7Q10 flows measured at the gauging
station; therefore, the City requests the effluent concentrations
be as follows:
a. Effluent Concentration with Wastewater Discharge at 12.48 CFS
(8 MGD) = 12.48 CFS x 100% = 11%
109 CFS
b. Effluent Concentration with Wastewater Discharge at 24.96 CFS

This is to provide you with the Lake Wylie Marine Comi.i'.ssion's
comments on the City of Gastonia's perm # NC0020184. The Marine
Commission is interested in this permi because it_�-scharges into
the South Fork River. Approximately #-the waters in Lake
Wylie are derived from the South Fork River. As you may know, the .
South Fork River is rated as only partially supporting.
The Lake Wylie Marine Commission is requesting that the permit
expansion not be allowed until the following areas are addressed.-'
The areas are: correction of violations; projection for expansion-7
needs.
Plant Violations
Over the past twelve months, this plant has experienced four
violations. The Commission is concerned about the number of
violations in such a short period of time. We can find no record
that either DEM or the City of Gastonia has developed a plan of
action for assuring that violations will not continue.
Should the expansion be allowed and the violations continue, we
will experience even larger problems in the South Fork River.
We therefore are request that the City of Gastonia and DEM develop
a plan of action for assuring that the violations do not continue.
In addition, we requesting that the plant be required to operate
for twelve months without a significant violation before any
expansion is authorized.

Dear Mr. Howard:
SEP
I am asking for a public hearing on the proposed NPDES
permit no. NC0020184 to be issued September 30, 1993,
concerning the City of Gastonia's permitted increase to 16
million gallons of sewage discharge per day from 8 million
gallons of treated domestic and industrial wastewater into
Long Creek there to flow into the South Fork of the Catawba
River rhich then goes into interstate commerce.
I am on the governing body of the City of Lowell which
purchases its water for domestic and business consumption
from the City of Gastonia. Lowell operates a s,ewer
treatment plant the single chief beneficiary of which is
Pharr Yarns, Inc., with Lowell's sewer plant being operated
adjacent to Pharr Yarns, Inc.'s, main plants adjacent to the
corporate limits of McAdenville and completely disconnected..
physically from Lowell.
Lowell has an engineering firm's recommendation to
repair and maintain its sewer system which it cannot finance
becauseI one favored sewer introducer into Lowell's treatment
plant is not paving its fair share nor anything near what
taxpaying citizens and residents of Lowell pay.
Even so, it would be appropriate that the Division of
Environmental Management conduct a public hearing and
receive comments concerning the City of Gastonia proposal.
One of the difficulties concerning knowledge of the
condition of water in the South Fork of the Catawba River is

Projection Of Expansion Needs
The City of Gastonia is currently requesting an expansion to its
plant. The Commission is concerned about how the expansion needs
were identified. In addition, what step(s) if any are being taken
to have any private discharge plants are taken off line and tied in
with Ga9tonia's system? We are requesting that a study be
undertaken to assure that the City of Gastonia is not requesting
too much capacity and reducing other dischargers' capacities
downstrem. In addition, we are requesting that the City of
Gastonia be required to implement a water efficiency program in
conjunction with any permit expansion.
Thank you for the opportunity to comment. Should you have
questions or need additional information please contact me.
Sincerely,
F. Michael McLaurin
Executive Director

that there is an insufficient number of sampling stations.
If I understand it c-Arrectly, there's a sampling station at
the donfluence of the South Fork of the Catawba River with
the main channel of the Catawba River at the South Carolina
line
there
Carol
in Gaston County. I have recently been informed that
is a sampling point in or near McAdenville, North
ina, which is downstream from Lowell's sewer effluent
discharge point. Upstream from Lowell there is a water
.intake point on the South Fork River for the City of
Gastonia, and numerous effluent discharge points,
specifically including Long Creek into which Gastonia
dischrges sewer plant effluent.
It is my observation that the South Fork of the Catawba
River is presently overloaded and is unfit for any use of
its waters in their present condition.
It would be appropriate that the Division of
Environmental Management work with the City of Lowell that
it might regain control of its sewer system as well as
cooperate with you and your department in returning the
South Fork River to a condition that would approximate those
days when it "ran as clear as a creek".
I would appreciate your .putting me on your mailing list
that I might comment on and participate in the reclaiming of
the South Fork of the Catawba River.
Sincerely,
Wade W. Mitchem

Other Environmental and Public Health Issues
While we are glad that Gastonia is, moving it's discharge from Long Creek where it has
caused severe water quality problems, we are very concerned about discharging not only
the currnt volume but especially the expanded volume above an impoundment. We
recommend that an Environmental Assessment be done that includes discussion of such issues
as the environmental fate of pollutants in light of the special hydrological conditions behind the
Spencer Mtn. Dam and the ects that might ff g be expected on existing water intakes a short
distance above Spencer Mtn. Dam.
Economic Issues
We are also concerned that the request for a doubling of the waste discharge will have a
profound effect not only on the water quality of the river but on the economic future of
downstream dischargers who may find most o the available waste loading tied up in
Gastonia's expanded discharge. We note thatpolicydecisions
tical
decisions are only now being formulated in relation to NC's basinwide
thesenam nt efforts.
management efforts.
We are concerned therefore that downstream dischargers be made aware of Gastonia's
proposal and be given an opportunity to comment on it. We request that notice be sent to
each of the downstream dischargers in the South Fork Basin.
We recognize that Gastonia is growing and producing more waste. But growth does not
have to pioduce as much waste as it has in the past. New methods and technologies can
significantly reduce waste production and be cost effective. Therefore, we believe that
Gastonia should be required to implement a water efficiency program in conjunction with any
proposed increase in waste water discharge. Such a program will help to extend the life of
existing and future treatment facilities as well as better protect our water resources.
Public Participation
Gastonia's1 request for permit modification is a significant change in the existing permit that
raises many complex issues of water quality as well as public health and economic growth
in the region.
There has not been a public discussion of these issues and therefore we request that a public
meeting be fteld and that the comment period be extended for an additional 30 days after the
public meeting g to allow
o for comments to be submitted after consideration of issues presented at
the public meeting. This extension of the comment period will also allow a more thorough
examination of the waste load allocation and other documents in the case.
Thank you 'for consideration of our views.
Sincerely,
Ginny Lindsey

MEMORANDUM

THRU: Ruth Swanek zo
Carla Sanderson
. Nowell �,I.�cquelyn M. Nowell /91\
SUI3JEC I : City of Gastonia 201 Facilities Plan for the Long Creek (NC0020184),
Catawba Creek (NC0020192),and Crowders Creek (NC0074268) WWTPs
Gaston County
The Technical Support Branch has reviewed the subject document and has the
following comments. The report addressed Gastonia's plan for expansion and upgrading
of the City's three wastewater treatment plants to accommodate future growth. The
alternative chosen by the City includes: 1) the expansion of the Long Creek facility from 8
to 24 MGD over a 20 year period, 2) upgrading the Catawba Creek facility with
phosphorus removal, but no increase in design capacity, and 3) the expansion of the
Crowders Creek facility from 6 to 9 MGD.
The report did not provide any information as to whether the receiving streams for
the Long Creek and Crowders Creek facilities would be able to accept the additional
wasteflows recommended in Phase II of the selected alternative, without any detrimental
impacts. The Division has recently completed a wasteload allocation for relocation and
expansion of the Long Creek WWTP from 8 to 16 MGD. However, Division staff have
not evaluated the expansion of that facility from 16 to 24 MGD or the Crowders Creek
plant expansion from 6 to 9 MGD. In the case of the Crowders Creek facility, it may be
beneficial to receive some input from environmental personnel from South Carolina since
Crowders Creek flows through their State. It is our recommendation that the potential
effluent limitations for these long term expansions be evaluated.
If there are any questions, please contact me.

Comments: Due to the presence of the ..pencer Mountain Dam pool downstream of the proposed discharge
pointthe facility should be required to install an effluent diffuser with multiple ports distributed across the
width of the river and a minimum of 10:1 initial dilution. The plume should avoid boundary interaction. i.e
bottom attachment, bank interaction. The oermittee should note that toxicity testing requirements and anv
existing or future chemical specific limits may be based on the dilution provided by the diffuser,

Wasteload Allocation Summary
The proposed discharge point is immediately upstream of a pool resulting from Duke
Power's operation of a modified peaking hydroelectric project at the Spencer Mountain dam. The
operation of this project limits the available assimilative capacity at the proposed discharge point.
Therefore, it is recommended that the facility receive advanced tertiary treatment limits. In
meetings with the State, Gastonia has been informed of this possibility and had previously agreed
to build an advanced tertiary treatment facility.
Due to the presence of the Spencer Mountain Dam pool, the facility should be required to
install an effluent diffuser with multiple ports distributed across the width of the river and a
minimum of 10:1 initial dilution. The plume should avoid boundary interaction, i.e., bottom
attachment, bank interaction. The permittee should note that toxicity testing requirements and any
existing or future chemical specific limits may be based on the dilution provided by the diffuser.

6/30/93
City of Gastonia, Long Creek
N00020184
- The City of Gastonia has applied for an expansion of the Long Creek WWTP from 8 to
16 MGD. In addition, they propose moving the discharge from Long Creek to the South
Fork Catawba River. A WLA will be done for three discharge conditions: 8 mgd
discharge to Long Creek, 8 mgd to the South Fork, and 16 mgd to the South Fork.
- Over the past three years the facility has been in compliance except for one recent
BODS violation during the transition from winter to summer limits. However, the facility
has had difficulty meeting the Toxicity Limit at 80%.
- The proposed discharge location, South Fork Catawba River at the mouth of Long
Creek, is 0.2 of a mile above a the Spencer Mountain hydro dam operated by Duke
Power. At that point, ;the South Fork is classified as WS-V.
- The 7Q10 on the South Fork above Long Creek is estimated by the USGS as 109 cfs,
(#0214390895, 12/07/88, DA: 558, QA 653, 30Q2: 272, w7Q10: 200). The dilution
available above Long Creek should reflect Gastonia's upstream water supply intake which
has a maximum capacity of42.6 mgd (1989 average 20.9 MGD). This means that as
little as 43 cfs could run at the discharge point during 7Q10 conditions, (206 cfs 30Q2).
For toxicant limits an IWC of 36% is appropriate for the 16.mgd discharge.
- The Spencer Mottnain Dam produces a pool on the South Fork almost immediately
downstream of the p posed discharge. A level-b analysis demonstrated that the
proposed discharge int, although not ideal, may be an acceptable location for the
discharge of 16 MGD of treated wastewater. Many assumptions about velocity and time
of travel were involve in this analysis. A 2/14/92 letter sent to Gastonia summarizes the
results of the level-b analysis and suggests limits of 10 and 4 for a 8 mgd facility
discharging to the Spencer Mountain Dam pool and 5&2 for 16 mgd.
Alternative discharge points discussed with Gastonia include remaining in Long Creek
and moving to the South Fork below the Spencer Mountain Dam tailrace. Long Creek is
already heavily used fix the assimilation of wastewater. If the proposed discharge was
released to Long Cree the IWC would be 89%. All facilities on Long Creek would be
required to meet tight rmit limits to protect water quality. Also, it is likely that
Gastonia would con ' ue to have difficulty meeting its toxicity requirements. If the
Gastonia Long Creek 'scharge was removed, the total IWC in Long Creek would drop to
46%.
Due to topography and the 1.5 mile Duke Power hydro project, considerable effort
would be required to pipe the effluent below the Spencer Mountain Dam tailrace. It is
felt that effort might be better spend in advanced treatment.

Based on the level-b model, existing limits, and meetings with Gastonia, the following
sets of summer limits are recommended:
8 mgd to Long Creek 8 mgd to South Fork 16 mgd to South Fork
BODS (mg/1): 11 (existing) 11* 5
NH3-N (mg/1): 17 (existing) 4 2
DO (mg/1): 5 (existing) 6 6
* This limit was not changed to 10 as suggested by the February 14, 1992 letter because
the facility may have trouble meeting this limit and effects on water quality are unlikely
to be significant since the facility will be upgraded for the 16 mgd discharge.
- To protect water quality in the South Fork Catawba River, it is important that the
effluent be well mixed with the receiving water before reaching the Spencer Mountain
Dam. It is recommended that a diffuser be designed and used to ensure rapid mixing and
dispersion of the effluent across the entire river. Multiple ports distributed across the
river and the EPA minimum recommended initial dilution of 10:1 should be required.

PART IV — EVALUATION AND RECOMMENDATIONS
The permittee, City of Gastonia, has applied for permit
modification for the Long Creek WWTP. The facility is currently an
8 MGD WWTP and will be expanded to 16 MGD. As part of the
expansion process, the facility will be upgraded to include
biological removal of phosphorus and effluentfilters.
The proposed expansion will utilize the same process that is
currently in place at the City of Gastoni.a's Crowders Creek WWTP.
That WWTP is currently having difficulties meeting the phosphorus
limit without chemical addition.
The facility is also proposing to relocate the outfall to the
South Fork Catawba River as part of the expansion process. There
are several small dams located along the river which affects the
currentl
It is recommended that the permit be modified upon concurrence
from the Technical Support Branch that the expansion will not
contribute to water quality standard violations.

performed by the Intensive Survey Group to address nutrient related
issues associated with the Gastonia Catawba Cr WWTP discharge.
Study was performed during the summer of 1988.
Mr. John Shuler, Assistant Director of Utilities with City of Gastonia, was
sent a letter from Water Quality Section Chief relaying results of the 1988
Intensive Survey and indicating violations of the State's chlorophyll -a
standard and that hypereutrophic conditions were due to excessive
nutrient loading.
North Carolina DEM and South Carolina DHEC jointly undertook a
comprehensive water quality data collection and analysis initiative aimed
at further investigating water quality problems in Lake Wylie and its major
tributaries.
DEM Director imposed a moratorium on new discharges as well as
expansions from US HWY 29/74 downstream to the state line including
all tributary backwater areas.
Mecklenburg County Department of Environmental Protection hostf,
"Lake Wylie Futures Forum Meeting" where water quality issues witiara
reviewed with representatives of North and South Carolina including
results of the initial year of sampling by NCDEM & SCDHEC. Much of
the focus centered around nutrient loading and subsequent
eutrophication concerns. Gaston County was represented at the
meeting.
DEM sent a response to Dr. Goldstein (w/ copy to Sam Wilkens, Gastonia
Public Works Director), Gastonia's environmental consultant, to provide
speculative limits for an expansion of the Gastonia Long Creek from 8
MGD to 16 MGD that could be used as a basis for an environmental

assessment (EA). The letter mentioned DEM's concerns regarding Lake
Wylie including the discharge moratorium. While final limits would
require additional assessment, the City was advised to plan for total
phosphorus (TP) limits as low as 0.5 mg/I , and total nitrogen (TN) limits
as low as 4.0 mg/I.
DEM staff met with City of Gastonia representatives and their engineering
consultant, J.N. Pease, at City's request to discuss future initiatives by the
City including expansion of the Gastonia wastewater treatment systems
at Long Creek and Crowders Creek. DEM again discussed the ongoing
nutrient issues and the discharge moratorium, and stated that the City
should plan on significant upgrade of WWTPs to meet state-of-the-art
pollutant removal levels given WQ problems in Lake Wylie and
tributaries, in order for staff to support a "Finding of No Significant Impact
(FONSI)" in the EA regarding their expansion plans. The engineers
representing the City confirmed that they intended to design the plant to
state-of-the-art levels.
Numerous meetings and correspondance took place between early 1991
and early 1992 regarding potential relocation of the Long Creek WWTP
outfall to the South Fork Catawba River mainstem. Most of the attention
was placed on location of the outfall (Le., upstream or downstream of
Spencer Mountain dam) and whether a set of interim limits could be
provided while the new facility was being built. On numerous
occassions, the plant's design engineers indicated their plans to include
biological nutrient removal and the expectation of meeting the proposed
TP & TN limits. The facility's Environmental Assessment indicated this
design and DEM issued a FONSI in November of 1991 partially as a
result of this and other mitigation measures committed to in the
assessment.
DEM completed its comprehensive modeling analysis of Lake Wylie and
several of its tributaries including the South Fork Catawba River and
Catawba Creek. Whereas the actual monitoring data collected during
1989 and 1990 documented the severity of existing problems, the
modeling analyses allowed staff to evaluate alternative control
mechanisms for point and nonpoint sources of nutrient loading. The
analyses demonstrated the need for both TP and TN removal at point
sources in both tributary arms into which the Gastonia facilities in
question discharge.
NCDEM & SCDHEC officially approved of a report documenting water
quality assessment, modeling analyses, and which outlines
recommendations for nutrient loading management in the lake mainstem
and tributaries. Draft NPDES permits for the Gastonia Long Creek and
Catawba Creek facilities were publicly noticed shortly thereafter with
limits consistent with the water quality based management
recommendations outlined in the report. As recommended in the report,
each facility was given 5 years to achieve compliance with the new
requirements.
