Dear Mr. Gore:

NORTH CAROLINA DEPARTMENT OF
ENVIRONMENT AND NATURAL RESOURCES
Subject: Final NPDES Permit
Permit No. NC0024228
High Point Westside WWTP
Davidson County
In accordance with the application for a discharge permit received on February 3, 1998, the Division is
forwarding herewith the subject NPDES 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 December 6, 1983, and as subsequently amended.
Please note the following changes from the previous permit (as indicated in the draft) have been finalized:
• Effluent Total nitrogen (TN) and total phosphorus (TP) monitoring has changed to weekly.
• A requirement to perform an Operation and Maintenance Assessment to identify methods of
optimizing phosphorus removal with existing facilities within one year of the effective date has
been added.
• Total Residual Chlorine (TRC) monitoring is not required if chlorine is not used for disinfection.
• Mercury and chromium limits have also been removed.
• The cyanide (CN) quantitation limit is 10 pg/l. A CN weekly average of 5.3 µg/1 and daily
maximum limit of 22 gg/1 have replaced the original daily maximum limit.
• Monitoring for copper, silver, and zinc has been reduced to 2/month, consistent with other Class
IV facilities.
• Chronic toxicity monitoring must occur in conjunction with metals and CN monitoring. This
coordination will ensure that future toxicity results and toxicant data can be compared.
• A footnote has been added that exempts this facility from instream monitoring, as long as the
facility is a member of the Yadkin -Pee Dee River Basin Association.
In response to your comment letter dated March 5, 1999:
Dissolved Oxygen (DO) Limit
You were correct in stating that the water quality standard for non -trout streams is 5 mg/1. The DO limit
in this permit, however, was determined by a field -calibrated model (QUAL2E) for oxygen consuming
wastes. The model predicted that even with a limit of 6 mJ1, Rich Fork is over -allocated, and instream
DO violations may still occur. For this reason, a DO limit of 6 mg/I remains in the permit.

Aluminum and Fluoride Monitoring
The renewal application indicated that phosphorus removal with alum would begin in the summer of
1998, and the Engineer's Certificate of Completion for phosphorus -removal facilities was received by the
Division on July 1, 1998. Aluminum is a pollutant of concern in the discharge because it is added during
treatment, and monitoring must therefore remain in the permit. Although there is no North Carolina
water quality standard, the U.S. EPA has established chronic and acute aquatic Iife criteria for Aluminum.
In the final permit, this facility is exempt from Aluminum monitoring, with the understanding that
the Long -Term Monitoring Plan (LTMP) will be modified as appropriate to include Aluminum (see
footnote on effluent page 2).
After a re-examination of fluoride data provided in the LTMP, fluoride monitoring was removed in the
final permit. Data indicate that fluoride loading to the plant is not significant enough to warrant effluent
monitoring in the permit.
Conventional Pollutants
The removal efficiency requirement for BOD5 and TSS of 85 percent is stipulated by the Secondary
Treatment Regulation (40 CFR §133), which is a federal requirement for all municipalities. Your letter
requested that removal efficiency be based on Chemical Oxygen Demand (COD) instead of BOD5;
however, there is no provision for replacing the percent removal requirement for BOD5 with COD in the
regulation. Since a reliable correlation between COD and BOD5 has never been demonstrated, the
Division would not have sufficient justification to require a COD removal efficiency in lieu of BOD5 in
an NPDES permit, regardless of the federal statute.
Reasonable Potential Analysis
Your letter stated that by using the Reasonable Potential to Exceed (RPE) method from Appendix E of
EPA's Technical Support Document for Water Ouality Based Toxics Control, limits for cadmium, lead,
and nickel should be removed. North Carolina does use a method approved by the EPA for performing
an RPE analysis which halves the value of the quantitation limit (QL) for the calculation, if measurements
are reported at that value. This assumption is statistically defensible and based on investigations by the
Division prior to submitting its RPE method for approval. In cases where the only reported detections are
considered outliers, no limit is imposed, even if half the QL is above the allowable concentration.
The Division feels its approach to RPE analysis is suitable and applies the method consistently to all
facilities across the State. Therefore, water quality -based limits for cadmium, lead, and nickel
remain in the final permit. We are interested in examining alternate statistical methods for assessing
reasonable potential; however, currently our staff resources are extremely limited. Should the facility still
feel that the method in Appendix E is superior to the method currently used by the Division, please send a
detailed letter and documentation explaining why North Carolina should consider using this method
instead. The Division is not averse to evaluating the differences between the two procedures and
deciding which statistical approach is preferable at some point in the future.
PIease note that the limits for cadmium, lead, and nickel have been modified in the final permit to
reflect a recently adopted policy. The daily maximum limits have been changed to weekly average
limits (appropriate for the chronic criteria on which water quality standards are based), and the new daily
maximum limits are based on a value incorporating acute criteria (half of the Final Acute Value, or
FAV). High Point may request a modification of toxicant limits after twelve (12) months of data are
collected, and the Division will again perform an RPE analysis to determine if limits are necessary.
Your letter also addressed metals requiring "monitoring only" in the NPDES permit that are also part of
the LTMP. The facility is exempted from monitoring mercury (Hg), as long as the Hg is included in
the LTMP (see footnote on effluent page 2). Monitoring for cadmium, lead, and nickel, however, is
required because limits are associated with each of these metals.

Nutrient Monitoring
In reference to your comment about the Total Phosphorus (TP) limit that will be imposed upon renewal in
2004, the limit has been clarified. The draft permit neglected to specify different limits for summer and
winter, and did not outline how any TP limit would be imposed. According the Basinwide Plan, High
Point —West Side will have seasonal total mass limits for TP. The TP limit shall be 5533 lbs. (approx.
26 lbs./day) during the summer (April -October) and 7808 lbs. (approx. 52 lbs./day) during the winter
(November -March). These loads are based on a 0.5 mg/l limit in the summer and 1 mg/I limit in the
winter, at High Point's permitted flow of 6.2 MGD.
Your letter also noted that the last sentence of the footnote regarding instream sampling was not clear for
nutrients. The table heading on effluent page 2 in the draft permit read "INSTREAM MONITORING
THAT IS REQUIRED JUNE-SEPTEMBER ONLY," and the table included the parameters Total
Phosphorus, NO2+NO3, NH3-N, and TKN. Up- and downstream monitoring for these parameters was
specified as 2/Month, rather than 2/Week. There were no changes to monitoring frequency in the final
permit, but the footnote has been modified.
Per a conversation with Mr. Bill Frazier on February 11, 1999, there were also concerns about the
notation used for Total Nitrogen (TN) on the effluent page. The table shows "Total Nitrogen (NO2 +
NO3 + TKN)." Measurements reported should be the total amount of nitrogen measured from those
constituents in the wastewater.
Quantitation Limits
Finally, the facility has expressed concern regarding the definition of the term "quantitation limit" in the
permit. Each specified quantitation limit is considered the "lower reporting level of the procedure" and is
consistent with the Test Procedures section in Part II of this permit. A statement of clarification has been
added to the effluent page.
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, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made,
this decision shall be final and binding.
Please take note that this permit is not transferable. Part II, E. 4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Land Resources or any
other Federal or Local governmental permit that may be required.

I've recently had conversations with Kathy Tyndall and Jim Blose. As
you know, Kathy works works with our monitoring coalitions while Jim has
been our point person with regards to nutrient strategies in the High
Rock Lake watershed.
Mike and Bethany - we need to put a special condition in the permits for
Thomasville and Lexington (Mike) and High Point Westside (Bethany)
requiring an optimization study for total phosphorus. I will forward
you specific permit language soon. Bethany - It looks like High Point
has already been noticed but not issued. They should be expecting such
a condition but you may want to give them a call to let them know that
you'll be including it.
Everyone - The Yadkin plan recommends that all dischargers in the High
Rock Lake watershed optimize their treatment facilities for total
phosphorus removal. This is a recommendation only. I told Jim and
Kathy that we can put this recommendation in the cover letter to the
permits. Again, I will forward specific language soon. If you have any
questions let me know.
Thanks,

Dear Mr. Goodrich:
Addendum: Comments on Draft NPDES Permit
City of High Point, Westside Wastewater Treatment Plant (WWTP)
NPDES Permit NC0024228
Davidson County
We wish to submit the following additional comments concerning issues that have arisen
since our letter of March 5, 1999 commenting on the subject draft NPDES permit.
Cyanide Limit and Monitoring
We have reviewed the draft research proposed by the University of North Carolina at
Chapel Hill concerning sensitivity and selectivity of the current approved method (EPA
SW-846/9012 or Standard Method 3400) for monitoring cyanide in wastewater. The US
Environmental Protection Agency has published the comment that the method may be
inadequate for some monitoring applications (40 CFR 136, 63 FR 36810, Guidelines
Establishing Test Procedures for the Analysis of Pollutants; Available Cyanide, July 7,
1998). Both the research and EPA comments represent a method that cannot be relied on
to accurately measure permit compliance for wastewater. We understand that other
methods have been proposed (same as above, throughout) and others that are currently
available in the research community that would overcome some of the insufficiencies of
the currently approved method. However, they are not yet are approved. We would
respectfully submit that including the method and permit limit is inappropriate until such
time as its inadequacies can be resolved.
Method Detection and Quantitation Limits
It has been brought to our attention in recent correspondence with legal council for the
American Canoe Association that the language in the permit concerning analytical limits
of detection are ambiguous. The current language can be interpreted in many different
PUBLIC SERVICES DEPARTMENT, P.O. Box 230, High Point, North Carolina 27261

non-standard ways. We would like to make sure that the permit language defines the
"lower level of detection" as the practically achievable sensitivity and selectivity in
wastewater matrix for the method using the best available technology.
We would appreciate it very much if you would include these comments in our revised
NPDES permit.

Dear Mr. Goodrich:
Subject: Comments on Draft NPDES Permit
City of High Point, Westside Wastewater Treatment Plant (WWTP)
NPDES Permit NC0024228
Davidson County
The purpose of this letter is to provide comments on the subject draft NPDES permit dated
February 10,1999. Our comments are organized according to General Comments, Toxicants
Limits/Monitoring, and Nutrient Monitoring.
General Comments
The City of High Point appreciates the changes that the Division of Water Quality (DWQ)
has made in response to our correspondence dated October 27,1998. Changes made
eliminating permit limitations, reducing monitoring requirements, and specifying a
quantitation level for cyanide are appreciated. We recognize the issues related to the
management of nutrients in the watershed to High Rock Lake are complex. We have
included some comments below to ensure that the City's rights are preserved as additional
nutrient control/monitoring requirements are imposed in the future. UV disinfection
facilities for the Westside WWTP are scheduled for completion by June 1999, so TRC
monitoring and a limitation should not be necessary.
Dissolved Oxygen
The dissolved oxygen limit in the draft permit is 6 mg/L. The water quality standard for
dissolved oxygen for non -trout streams is 5 mg/L. Rich Fork Creek is not a trout stream.
Therefore, we feel that the dissolved oxygen limit should be 5 mg/L.

,Aiuminum
Aluminum monitoring was added to the draft permit. There is no action level or water
quality standard for aluminum, therefore, we do not feel that aluminum monitoring should
be required. Aluminum can be analyzed as part of the Long Term Monitoring Plan (LTMP)
if data is considered necessary.
o \I
/F1uoride
Fluoride monitoring was added to the draft permit. The West ' • - . acility does not receive a
significant fluoride load from industrial users. The highest dusty average fluoride
concentration for 1997 was 1.151 mg/L which is lower than e water quality standard of
1.8 mg/L. Therefore, we do not feel that fluoride monitoring should be required. Fluoride
can be analyzed as part of the LTMP if data is considered necessary.
Conventional Pollutants
A removal efficiency requirement of 85 percent was added for BOD and TSS. We feel that
the BOD and TSS numerical limitations on the effluent are sufficient to protect water quality
of the receiving stream. In addition, influent BOD values may not be representative of the
actual organic loading to the plant, beca influent can be inhibitory in the BOD test.
We feel that removal efficiency based o COD emoved wo ld better reflect organic ,

' it 1 exceed (RPE) analysis performed by our consultants and by DWQ. While we agree with the

' ° �� decisions to eliminate limits for mercury and chromium, we believe elimination of limits for
n01• e`, additional parameters are warranted. Table 1 includes an analysis of data for a three-year
f period from 1996 through 1998 for cadmium, chromium, lead and nickel.

The RPE values in Table 1 were calculated for the Westside facility using the procedure
outlined in Appendix E of EPA's Technical Support Document for Water Quality Based Toxics
Control (TSD) as discussed in a letter from Tom Gore to Dave Goodrich dated October 27,
1998. The Appendix E method provides the best estimate of RPE values, particularly for
data sets with some values below the detection level. This distinction is important for
cadmium where the routine detection limit used for compliance monitoring is 5 ug/L (more

than double the permit limitation). In contrast, DWQ used the Chapter 3 method (short
version) from this same reference which is an approximation of the Appendix E method
and less accurate. The Appendix E method is accepted by EPA, and we feel that it more
accurately estimates an RPE value for a large data set with some values below the detection g-
level. Appendix E RPE values for cadmium, lead, and nickel are below the water quality 1`" -
standard and proposed permit limitation, and these metals were only detected in a fraction
of the samples analyzed. Therefore, we believe that limits for cadmium, lead, and nickel __
should also be removed from the permit.

In addition, the majority of the metals included in our permit for ' onitoring o " are also �,,,,,,

Bethany,
Attached is the spreadsheet I developed to estimate RPE values using TSD
Appendix E Table E-1. The raw data is entered into the 'data' sheet. The
'data' sheet is designed to enter data for up to 10 compounds and up to 200
data points. The calculations for Compounds 1 through 8 are for a data set
with some values below the detection level. Compounds 9 and 10 are for data
sets with all values above the detection level. There is a sheet for each
compound which calculates the RPE value ('Compound 1', etc). The
calculation sheet follows the equations in Table E-1 with one exception.
For data sets with some values below the detection level, z* must be
calculated (for data sets with all values above the detection level, z* is
2.326 for the 99th percentile, and 1.645 for the 95th percentile). z* is
based on 1/phi(greek letter). However, the TSD does not provide a method to
determine 1/phi. Therefore, equations obtained from a statistics book were
used to calculate z*. (I don't have access to this book at the moment, but
I can send you the appropriate pages if you would like). The 'summary'
sheet summarizes the calculated RPE value for each compound entered. I have
sent you the spreadsheet for the most recent RPE analysis (data from 1/96
through 12/98), but I can send you the prior spreadsheets also.
If you have any questions, please call me. Monday through Thursday of this
week I can be reached at 409-626-3110. After Thursday, I can be reached in
Charlotte at 704-329-0073 x228.
Thanks,
Kristen

statistical approach whereas the state's language in the permit is more aligned with practical application of
the analytical technique in wastewater matrix. Give us a call if you have any questions and I'll forward the
extra comments as soon as they are complete.

Dear Mr. Gore:
Thank you for your prompt responses to the questions I had concerning the Discharge •
Monitoring Reports (DMA.), and back-up data. We acknowledge the master sheets were lost in a
computer failure, and the situation has been rectified. The use of "TOX" to indicate analysis is
understood.
Following a review. of Standard Methods, Section 10.10.C-Defined Limits of Detection, we find
the definition to be different than Part II of the permit, Test. Procedures. As it is stated in the
permit; "...all test procedures must produce minimum detection and reporting levels that are
below the permit discharge requirements and all data generated must be reported down to the
minimum detection or lower reporting level of the procedure". According to Standard Methods
the definitions for lower level of detection (LLD), method detection limit (MDL), and practical
quantitation limit (PQL) are as tllows;
• LLD— the amount of constituent that produces a signal sufficiently large that 99%
of the trials with that .amount will produce a detectable signal.
• MDL— differs from the LLD in that samples. containing the.constituent of interest
are processes through the complete analytical method. The MDL is greater than
the LLD because extraction efficiency and extract concentrations factors.
• PQL= the PQL has been proposed as the lowest level achievable among
laboratories within the specified limits during routine laboratory operations. The
PQL is about five times the MDL.
By review of the laboratory sheets, it appears that you are reporting a value less than (c) the PQL
(Le., using the PQL as the minimum detection level for the procedure). The MDL should be used
as the lower level of detection rather than the PQL, as required by the permit. The laboratory
sheets should also provide the MDL.

Special Condition(s):
Compliance History
WET Testing —Chronic (Ceriodaphnia) P/F at 90%.
• In general, this facility does not have a good compliance record. Civil penalties have been assessed
at least three times in the past two years.
• During 1996, facility had sequential toxicity test failures the first four months. Record has improved
since then (see attached record); however, an NOV was issued 12/21/98 for a toxicity test failure. An
NOV was also issued 6/23/97 for a toxicity failure... not recorded in database?
• 11/7/97 Memo from Matt Matthews stated that grab samples taken in 10/97 failed toxicity tests.
• Has facility conducted a Toxicity Reduction Evaluation (TRE)?

ti
Staff Review and Evaluation
NPDES Wastewater Permit (NC0024228) Fact Sheet
• Civil penalties were assessed in 10/97 for several violations that occurred during 1996. Some
violations cited were not assessed, however, because they resulted from power outages during -
Hurricane Fran.
• 2/10/97 Compliance Inspection Report noted several violations cited in the 10/97 Assessment, in
addition to 162 instances of failure to report data on DMRs with adequate frequency.
• Civil penalties were assessed in 10/98 for a sewage overflow in 3/98, which resulted in a fish kill.
• 8/18/98 Compliance Inspection Report included an NOV for 5 BOD5 limit violations, 3 fecal limit
violations, 5 CN limit violations, and a DO limit violation, all occurring in 1998.
• Average flows dropped over 1998, beginning near 5 MGD, and tapering off to about 2.5-3 MGD.
Similar pattern in '97. Seasonal industries?
• TRC tends to run around 400-500 41. Levels should drop when facility begins using UV -
disinfection system. Fecal levels normally low (<20/100 ml), with exception of 1/98-3/98; levels
higher on average in '97.
• Effluent pHs and DO levels have been normal '97-'98; TSS normally below 10 mg/1.
• Average effluent BOD5 normally <10 mg/1 or slightly above, depending on time of year (normal
seasonal fluctuation); ammonia levels are very low —usually well <0.4 mg/1 (highest in 2/98-1.3
mg/1.)
• Effluent TN and TP levels tend to run 9-15 mg/1 and 1-3 mg/1, respectively, in '98. Similar levels in
'97, with TP around 4 mg/1 a few months. Meeting 2.0 mg/1 TP limit as of October 1, 1998. Effluent
nitrites & nitrates and effluent TKN normally variable: range from 2-15 mg/I with no trend.
• Facility has been monitoring for aluminum and iron, though it is not required in the current permit.
Fe levels are typically <500 µg/l, and Al levels are usually <500-700 µg/1(an increase in '98
presumably from alum phosphorus removal installation).
• Instream data available '97-5/98 (facility joined Yadkin -Pee Dee River Basin monitoring
association): normally slight drop in DO between upstream and both downstream locations, but
levels well above 5.0 for '98; no trend in fecal or conductivity; temperatures normal. '97 patterns the
same, with up- and downstream DOs falling closer to 5.0 during summer months. Ammonia usually
<0.01 mg/1; TKN usually 0.3-0.4 mg/1; nitrites & nitrates usually 0.3 mg/1, and TP normally 0.06-0.2
mg/l.
Additional Comments
• Ammonia toxicity calculations indicate an allowable concentration of 1.1/2.1 mg/1 (S/W), which
could normally be assigned to major facilities (Division policy is not to assign ammonia limits any
more stringent than 1/2 mg/1 (S/W) to majors); however, facility is already meeting 2/4 mg/I (S/W),
and levels are typically well below that level. Facility also monitors chronic toxicity; therefore, no
change in limits is recommended.
• Dilution calculations also indicate an allowable concentration of 18 µg/1 for TRC. Since facility will
soon utilize UV disinfection, no limit was incorporated into the permit upon renewal.
• Rich Fork is impaired (partially -supporting) and listed on the 303(d) list. Problem parameters
include fecal coliform. Again, facility's use of UV disinfection should benefit the stream.
• This discharge is located in the Abbott's Creek sub -basin, which is heavily affected by phosphorus
loading, and this facility has taken steps to reduce its contribution. A QUAL2E model developed in
1989 (incorporated into the 1993 model to account for this discharge) indicated that Rich Fork is
over -allocated, with the most pronounced DO sag occurring just above the confluence of Hamby Cr.
No new discharges of oxygen -consuming waste are recommended per the basinwide plan.
• The Basinwide plan also states that major facilities in 03-07-07 would receive mass TP limits based
on 0.5 mg/1 and 1997 permitted flow upon renewals in 2003 (though renewal schedule has shifted to
2004). Per Jim Blose of the Modeling/TMDL Unit, this requirement will replace any previous TP
requirements upon expansion and TN is not currently a major concern.

Staff Review and Evaluation
NPDES Wastewater Permit (NC0024228) Fact Sheet
• In 1996, DWQ denied a speculative limits request by High Point because of the over -allocation of
Rich Fork.
• Since NC standards are based on chronic criteria, upon request, the Division will impose a weekly
average for CN based on the allowable concentration calculated from the IWC. However, because
the stream must be protected for both chronic and acute effects, a daily maximum limit of 22'µg/1('/2
Final Acute Value, or FAV) is imposed in addition to the weekly average. In light of information
available on measurement techniques, the Division feels it is reasonable to specify a quantitation limit
for CN as 10 µg/1 and is making the change as permits are renewed or upon a request for
modification.
• Long Term Monitoring Plan (LTMP) data indicated some SIUs discharging to the City are
contributing significant amounts of fluoride to the influent. Monitoring is re ommended as part of
this renewal. A.,eim-erzi-ec(- a.vhd - .M,of ,� c �c� �?i�o , .44f..4-rye
• The facility requested cadmium, chromium, nickel, and lead limits be removed, as well as monitoring
for these parameters be discontinued. Based on the NC method for Reasonable Potential Analysis ''"••
(which varies slightly from the original EPA method but has been approved by EPA), only chromium
and mercury limits were justifiably removed. Monitoring for chromium can be removed because it is
part of the LTMP.
• It is unclear whether or not facility monitors for mercury as part of LTMP, so monitoring remains in
this draft permit. Pretreatment Unit will confirm. Copper and zinc are also part of the LTMP;
however, there is reasonable potential for these metals to exceed action levels, so monitoring remains
in the draft permit, as well. C 1 u' tt10 — A/`b C r.v
• No record of Engineering certification from facility for completion o lum faci i ' or UV
disinfection. Since renewal application only indicated that alum f,9cilities wpuld be operational,
installation of UV -system was assumed incomplete. A,t,C

. 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 January, April, July and October. 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. Future Nutrient Limits
e facility shall meet the following nutrient limi(asof October 1,1998:
-- Total Phosphorus - 2.0 mg/1 (summer/winter). Monitoring frequency will change to weekly.
The facility shall meet the following nutrient limit upon expansion:
Total Phosphorus - 0.5 mg/1 (summer/winter).

�A total nitrogen limit of 4 mg/1 (summer) and 8 mg/1 (winter) will be added during the

NOTES FOR HIGH POINT- WESTSIDE
PERMIT RENEWAL (NC0024228)
Industrial and sanitary wastewater discharge from High Point— Westside Plant (High
Point, Davidson County) to Rich Fork in the Yadkin -Pee Dee River Basin.
15A NCAC 2B .0300 Index # 12-119-7: Classified as C.
Recent ATC Information:
• ATC issued 5/19/97 for alum phosphorus removal facilities. Once operational,
aluminum monitoring should probably be added to the permit.
• ATC issued 3/27/98 for UV disinfection system.
Basinwide Plan Information:
• Facility discharges into Rich Fork in the Yadkin -Pee Dee River Basin (03-07-07).
This discharge is located in the Abbott's Creek sub -basin, where the general water
quality is only Good -Fair. Elevated fecal coliform concentrations have been
recorded in Rich Fork near Thomasville, and concentrations of copper, iron, and
nitrate/nitrite were also frequently elevated. These could be indicative of non -
point runoff.
• Mercury contamination was identified in the upper reaches of Abbotts Creek and
Leonards Creek around Lexington from fish tissue analyses, mainly the result of
Duracell USA battery plant in Lexington. Fish consumption advisory was lifted in
3/92, and mercury is continuing to decline to background levels.
• Rich Fork is rated as partially -supporting (impaired) and is listed on the 303(d)
list. Problem parameters include fecal coliform. An ambient station (#0212147355)
is located at 1800.
• In 1993, the Division completed a field -calibrated QUAL2E model of Hamby Cr
and Abbotts Cr below Thomasville, which also included the High Point discharge.
The model indicates that Hamby and Abbotts have little additional assimilative
capacity for O2-consuming wastes, a conclusion generally supported by ambient
data. Also, most of the phosphorus load to Abbotts and High Rock Lake (heavily
impacted by phosphorus) originates from High Point, Thomasville, and Lexington
discharges.
• Recommendations: no new 02 consuming wastes in this watershed and significant
phosphorus loading reductions, especially for the above major facilities. In 2003,
each of these three dischargers will receive summer and winter mass TP limits (see
1/7/99 email from Paul Clark). Within one year from 1998 renewal, each of
these permittees must conduct an operation and maintenance assessment to
identify methods of optimizing phosphorus removal with existing facilities
and must submit a report to DWQ documenting actions taken. This language
should be included in the permit.
• Although upgrades in mid-80's at High Point improved water quality, substandard
DO concentrations continue to persist during summer months. The QUAL2E
model developed in 1989 (incorporated into the 1993 model to account for H.P.'s
discharge) predicted that Rich Fork is over -allocated, with the most pronounced
DO sag occurring just above the confluence with Hamby Cr.
WLA Information:
• See attached copy of 11/22/96 letter
• Long-term BOD analysis done 5/16/96 indicated CBOD/BOD5 multiplier = 5.04.

NC0024228 BAB
• As of October 1, 1998, the facility, is meeting a 2.0 mg/1 phosphorus limit, with
weekly monitoring. Upon expansion, it is to meet a limit of 0.5 mg/l. These
limits were incorporated as a special condition in the previous permit (following
WET testing). This condition also specified that a nitrogen limit of 4/8 mg/1
S/ would be added to the permit at next renewal.

Correspondence:
• NOV issued 12/21/98 for toxicity test failure.
• Civil penalties assessed 10/9/98 for 3/15 overflow of sewage, resulting in a fish kill.
• NOV and Assessment of Civil Penalties issued 8/28/98 for BOD5 and CN limit
violations in 5/98.
• 8/18/98 Compliance Inspection Report included NOV for 3 monthly average
BOD5 violations during 3-5/98; 2 weekly average BOD5 violations during 3-4/98;
3 weekly average fecal coliform violations during 11/97-3/98; 5 CN limit violations
in '98; and a DO violation in 4/98.
• 11/7/97 Memo from Matt Matthews stated that grab samples taken in 10/97 failed
toxicity tests.
• 10/3/97 Assessment of Civil Penalties issued for attached list of violations from
Jan. `96-Nov. '96.
• 6/23/97 NOV issued for toxicity violation.
• 2/10/97 Compliance Inspection Report noted several violations cited in the 10/97
assessment, in addition to 162 instances of failure to report data on DMRs at the
correct frequency. No obvious maintenance problems were noted, and the RO
acknowledged, that the plant had been plagued by numerous mechanical failures
during the period in question (1996)... including the hurricane in September.
Data Review:
Toxicity Test Results
Period in 1996 of non-compliance; seems to have improved in past two years.
DMRs
• Effluent average flows dropped over 1998, beginning near 5 MGD, and dropping to
about 2.5-3 MGD. Flows in 1997 followed a similar pattern. Seasonal industries?
• TRC typically are 400-500 µg/1.
• pHs are normal.
• Average BOD5 normally < 10 mg/1 in the latter half of the year; closer to 10 mg/1
until March, 1998. In 1997, average < 10 mg/1.
• Average ammonia levels very low— usually well < 0.4 mg/1 (highest in Feb. 1998-
1.3 mg/1).
• TSS normally below 10 mg/1.
• Fecal levels normally low (< 20/100 ml), with exception of Jan. -Mar. 1998. Levels
were slightly higher on average in 1997.
• Effluent DOs normally 7-8 mg/1.
• Effluent TN and TP levels tend to run 9-15 mg/1 and 1-3 mg/l, respectively in
1998. Similar levels in 1997, with TP around 4 mg/1 a few months.
• Facility is also monitoring for aluminum and iron... ? Not in permit. Al levels
usually < 500-700 µ 1; Fe levels usually < 500 µg/1 (1998). Al levels increased
slightly in 1998— pro ably due to alum phosphorus removal facilities.
2

NC0024228 BAB
• Effluent nitrates & nitrites and effluent TKN normally variable; range from 2-15
mg/1 with no discernible trend.
• Instream data: available through 5/98; faciltiy joined monitoring association. See
fact sheet.
New expiration date: April 30, 2004.
Ammonia Limits
Ammonia toxicity calculations indicate that limits of 1.1/2.1 mg/1 (S/W) will protect
against toxicity. Division policy is to assign minimum ammonia limits for major
facilities no more stringent than 1/2 mg/1 (S/W). Since. current levels are well below
allowable concentrations,and the facilityalreadymonitors toxicity,the limits will
remain 2/4 for this renewal.
LTMP Data
Swaim Metals appears to be a significant contributor of nickel and chromium.
Interesting to note that facility also monitors for fluoride (the heaviest contributor of
which is Superbrand Dairy), which is not included in the NPDES permit. The
standard for fluoride is 1800 µg/l; theref re, fluoride monitoring 2/Month is
recommended for this permit cycle. 3 3 o 9 ff - ,e0 ,, 444

Facility currently monitors discharge as part of the LTMP 3 consecutive days per
quarter. o eV of i N Ftu�N'r PATH renvi) D , e-F 0i4 tJeVVR R-ce?v aD.
Facility's Request to Drop Limits:
Facility submitted data, as well as the results of RPE ("Reasonable potential to exceed")
analysis (method used was from EPA support document), to request that some limits
be removed. A reasonablepotential analysis(NC method)was performed on data
Y
submitted, since this is consistent with DWQ's approach to all NC facilities.
Reasonable Potential Analysis
• Chromium and mercury limits may be removed upon renewal.
• The facility cited the incorrect action level of silver as 60 µg/1, rather than 0.06
µg/l. Monitoring should be 2/Month.
• For nickel, whether or not the value 55.13 was considered an outlier determined if
this parameter should be limited. Because of the significant increase in number of
detects since June, 1998, this value was not considered an outlier, and a limit is
recommended.
• For some parameters (Cd, Pb, Ni), the calculated allowable concentration is
slightly off from the current limit; this is probably due to rounding , (and then
adding ".0" because of measurement capabilities), as there are no specific notes in
the WLA files that explain assimilative capacity for these contaminants is
exhausted. Because of anti -backsliding rules, the limits for Cd and Ni will remain
as they are. Lead will be modified to 26.7 µg/1.
Monitoring requirements
We can only rant a request to eliminate monitoring for the above metals without
limits if there is sufficient monitoring in the Long Term Monitoring Plan .(LTPM for
Pretreatment): There would be no way to perform reasonable potential analyses
without data in the future, unless the toxicant in question is no longer a pollutant of
concern. Monitoring can be reduced, however, to 2/Month. (Normal practice is to
3

NC0024228 BAB
assign monitoring for toxicants without limits of 2/Month for Class III and IV
facilities).
Since chromium is part of the LTMP, monitoring may be removed from the NPDES
permit. It is not clear whether or not mercury is also part of the LTMP, but if so, Hg
monitoring may also be eliminated from the permit. Zinc and copper are also in the
LTMP but show reasonable potential to exceed the action level, so monitoring in the
NPDES permit will be 2/Month.
In addition, more frequent nutrient monitoring (weekly) will be instated during this
permit renewal, per the 12/7/98 memo from Steve Pellet.
CN Limits
A CN quantitation limit of 10 µg/1 is reasonable and also consistent with other recent
permit modifications. As with the Eastside plant, we can move the daily max. to a
weekly average and set a daily max. at lh FAV (22 µg/1).

Steve, Bethany,
Please pass this info on to others. I just spoke w/ J. Blose. It was
his understanding that the statement in the Yadkin basin plan replaces
previous conditions in permits. For Highpoint Westside WWTP, the TP
mass limit (using 1997 permitted flow and 0.5 mg/1 concentration) to
become effective in 2003 (or 2004 since that is now year of next
renewal) would replace the 0.5 mg/1 limit to be implemented upon
expansion. Jim also said he believed the 4/8 total nitrogen condition
would also no longer be valid. He went on to say it would be a good
idea to confirm this w/ Dave. Thanks to both of you for your help.

Chapter 6 - Water Quality Concerns and Reconunended Management Strategies
Hamby (Not Supporting) and Abbotts Creek (Support Threatened)
In 1993 the Division completed a field -calibrated QUAL2E model of Hamby Creek and Abbotts
Creek below Thomasville. The model also included the High Point discharge by incorporating the
output from the Rich Fork QUAL2E model in the analysis. The model indicates that Hamby and
Abbotts Creeks have little additional assimilative capacity for oxygen -consuming wastes. Water
quality sampling in these streams generally supports this conclusion. Substandard DO
concentrations have been reported in Abbotts Creek above and below the Lexington discharge
(Lexington's downstream sampling point is at NC-47, on the Abbotts Creek arm of High Rock
Lake). Occasional DO violations have been reported both up and downstream of Thomasville's
discharge. Hamby Creek is also impaired due to sedimentation and elevated fecal coliform bacteria
levels.
Most of the phosphorus load to the Abbotts Creek arm of High Rock Lake originates from the
High Point, Thomasville and Lexington discharges. Because of this, substantial reductions in the
loading from these facilities is necessary to minimize the frequency, duration and extent of
nuisance conditions in this atm of the lake.
Recommendations:
DWQ recommends that no new dischargers of oxygen -consuming wastes be permitted in the
Abbotts Creek watershed, which includes Hamby Creek. Thomasville and Lexington should serve
as regional treatment facilities to handle future wastewater needs. Given the limited assimilative
capacity of Hamby and Abbotts Creeks both municipalities are encouraged to aggressively pursue
reuse options before additional loadings of oxygen -consuming wastes are permitted.
Nutrient Ioading from the major facilities in this suhbasin heavily impacts the Abbotts Creek arm of
High Rock Lake. The Lexington, Thomasville and High Point Westside WWTPs will be required
to make significant reductions in phosphorus loading. In 2()03 each of these three dischargers will
receive summer mass TP limits based upon its current (1997) permitted tlow capacity and a TP
concentration of 0.5 mg/1 [mass TP limit in kg = permitted flow in MGD x 0.5 mgll x unit
conversion factor of 3.79 x number of days in the summer period]. The total mass TP limits for
April -October (214 days) are as follows: High Point 2568 kg (an average of 12 kg/day), Lexington
2140 kg (10 kg/day), Thomasville 1712 (8 kg/day). These facilities will receive winter limits
(November -March, 151 days) based on twice the average summer daily levels as follows: High
Point 3624 kg (an average of 24 kg/day), Lexington 3020 kg (20 kg/day), Thomasville 2416 (16
kg/day). Within one year from the beginning of the 1998 permit cycle, each permittee must
conduct an operation and maintenance assessment to identify methods of optimizing phosphorus
removal with existing facilities and must submit a report to DWQ documenting actions taken. oy01:1.
Fo. cAt_cs.
As a result of this TMDL strategy, summer end of pipe TP loads to the Abbotts Creek arm will -
decline to one fifth of 1994-96 levels. Ambient phosphorus levels are predicted to decline by 30 to
40% in the upper portion of the Abbotts Creek aim and by 20 to 25%, in the middle portion of the
arm (NCDWQ, 1997a). Local governments in the Abbotts Creek watershed are strongly
encouraged to implement programs to reduce nonpoint source phosphorus Ioading and to develop
strategies for managing shoreline development.
Additional activities and resources are needed to identify impairment sources on Hamby Creek and
to develop management strategies for this waterbody. As resources allow, DWQ intends to
develop NPS management strategies for this waterbody for the second Yadkin -Pee Dee River
Basin Plan (refer to Section 6.3.3). In addition, local efforts are needed to develop a plan to
reduce nonpoint source pollution on Hamby Creek.
Brushy Fork (Partially Supporting)
Approximately ten miles of Brushy Fork is considered impaired priiriarily due to nonpoint source
pollution with sedimentation as the primary cause of impairment.

Dear Mr. Kairis:

November 22, 1996
Subject: Request for Speculative limits
High Point Westside WWTP
NPDES No. NC0024228
A request for speculative limits, submitted by Randy McNeill with Davis -Martin -
Powell & Associates, Inc., has been reviewed by the Water Quality Section. In response
to low instream dissolved oxygen (DO) concentrations which have persisted since the early
1980s, a field calibrated QUAL2E model was developed in 1989 for Rich Fork Creek.
This model framework was used to assess the potential impacts of an expanded wasteflow
from 6.2 MGD to 9.3 or 12 MGD.
The modeling analysis indicates that Rich Fork L'reek has no assimilative capacity
for additional waste flow treated to meet advanced tertiary limits (BOD5= 5 mg/L and
NH3-N= 2 mg/L) during critical summer low flow (7Q10) conditions. The 7Q10 flow is
defined as the lowest seven day average flow with a ten year recurrence interval. The
Division of Water Quality uses this statistic as the design stream flow for determining waste
load allocations throughout the state. In Rich Fork Creek the model predicts the minimum
dissolved oxygen (DO) concentration to be less than 3 mg/L for waste flows of 9.3 and 12
MGD. The US Environmental Protection Agency has indicated that 3 mg/L is the threshold
DO concentration needed for the survival of many freshwater aquatic species. The North
Carolina water quality standard for dissolved oxygen is 5 mg/L.
In order to assess the accuracy of the model predictions, US Geological Survey
stream flow data was examined to identify recent periods of low flow in the Abbotts Creek
drainage basin. After examining the past five years of records, October 1993 was
determined to be a period in which stream flows most closely approximated 7Q10
conditions. During this period the WWTP was discharging at approximately one half its
permitted wasteflow and instream DO levels as low as 3.8 mg/L were reported in the City's
discharge monitoring reports (DMRs). To test the model, effluent data taken from October
1993'DMRs was input into the model, and the predicted minimum DO concentrations were
compared to the City's instream measurements. From this analysis it was determined that
the model was yielding reasonably accurate predictions with a differential of less than 1
mg/L from the observed values. Since the model was originally developed in 1989 based
on data collected in 1975 and 1986, the Division of Water Quality recognizes that improved
predictions may result from updating the data sets used to calibrate the model.

The Division acknowledges the improvements in water quality that have resulted
from the treatment plant upgrades that were made in the mid 1980s. However, even
though the City currently is treating to meet advanced tertiary limits, violations of the state
standard for dissolved oxygen continue to occur in Rich Fork Creek each summer.
Attached is a graphical summary of recent instream DO concentrations at the current
monitoring stations specified in the City's NPDES permit.
Considering the observed water quality problems at the present waste flow, and the
predicted impacts from an expanded waste flow, the Division of Water Quality cannot
supply speculative limits for the expansion of the High Point Westside WWTP at this time.
The Division would be happy to meet with the City and its consultants to discuss the
modeling analysis and possible wastewater treatment and disposal options.
If you have any questions, please do not hesitate to contact Mr. Donald Safrit,
P.E., Assistant -Chief for the Technical Support Branch or Ms. Ruth Swanek, Supervisor
of the Instream Assessment Unit at 733-5083, extensions 519 and 503, respectively.

General notes:
1) We already do a lot of monitoring in plant, this LTMP
is to be performed.in addition to the regular monitoring.
I proposeto do the in plant LTMP monitoring starting
during the week of March 1, 1993.
2) In addition, I propose to have as much of the standard
plant monitoring performed by Graphite Furnace as pos-
sible.
The
3) design detention time ' for the primary clarifiers
is ' 2.7 -hours , .the secondary clarifiers is 5.2 hours and
the biofilter is believed to be less than that of the
primaries. All these are design detention times only. Be-
cause of the fact that the sampling will consist of 4
daily composites, the detention times are small by com-
parison* and can be ignored.
A. Sampling Points
1) Influent As discussed for flow measuring points in
item 1 above, it is impossible to collect samples before
any side streams are added. Except for the flow equaliza-
tion return flow, these sidestreams are expected to be
small in relation to the total flow. What I propose to do
is to collect time proportional composite samples from
each outfall above the sidestreams and composite those
based on estimated flow. We already collect a composite
sample at the headworks. This will be compared with the
composite sample from the outfall lines to evaluate the
effect of the sidestreams.
2) Effluent: No problem, we already collect these.
3) Primary Effluent: The effluent from the primary
clarifiers can be collected easily. The influent to the
Biofilter is going to be hard to collect, see #8 below.
4 & 5) Primary and Secondary sludge to digestor: They are
combined into one flow. I propose to sample the mix of
the two rather than trying to separate them.
6 & 7) Primary and Secondary Sludge to disposal. No
problem, we already collect these.

Westside
8 Biofilter: This. wastestream can be monitored. However,
its value is questionable because the influent to the
Biofilter, the effluent from the Biofilter, the activated
sludge return line from the secondary clarifiers and a
lime feed line all'go to a single large mixing box. See
figure 1, attached. In other words the biofilter is a
side process which has no effect on metals. However it,
does 'remove a cohsiderable amount of COD. Therefore .I
plan to sample it for BOD, COD, TSS, and Ammonia.
9 Sampling: The POCs are Ammonia, COD, the normal seven
metals and mercury. BOD, TSS and cyanide are omitted from
this list for the same reasons as for Eastside.
Upstream: The'City collects'upereek samples about 100
feet above the outfall. This is where the upstream
samples will be collected for the LTMP.
Downstream: The City has 4 downcreek sampling points:
Kany Road (sampling point 9), Evans Road (sampling point
9-b), a Railroad bridge (sampling point 9-C), and
turner's Creek (sampling point 9-D). The downstream
samples will be collected at Kany Road, (9-b).
I propose to do the minimum amount of sampling required
by the state. From July to August, and in October, I
plan to collect one sample per month at the upstream sam-
pling point and one at the downstream sampling point.
During September we will collect one sample each week
during the first and third weeks.
10 Uncontrollable: Shall be monitored as described in the
collection system of this plan.
11. Septage Haulers: There is very little septage hauled
to this plant, from September 21, 1992 to December 3,
1992, there were only 21 loads of 1,000 gallons of sep-
tage discharged at Westside. What I propose to do is,
after approval of this plan, to collect samples from the
first 5 septage haulers that come to the plant. These
samples shall be analyzed for COD, metals and cyanide.
This is to be followed by taking one sample from the
first load of..-septage that comes in each month for a
year Septage is collected at a fixed station from which
it goes to the headworks.
•l.

B. Pollutants of Concern: BOD, COD, TSS, Ammonia,
Cyanide, Cadmium, Chromium, Copper, Lead, Nickel, Silver,
Zinc, and Organic chemicals. Mercury has been detected in
Westside's effluent. Therefore, for now, mercury is con-
sidered to be a POC.
C. Detention Times: The detention times are believed to
be: for the plant as a whole 24 hours, for the digestors,
a month.
Westside:
D. Flow Monitoring Plan:
Note: All monitoring and sampling points are numbered ac-
cording th hp in the TDEM LTMP attachment B
trVl.d illy to the scheme elt\e LL11S ..1 �. .1 .. ..,
Primary/Activated Sludge/Anaerobic Digestor LT24P model.
1) Headworks: Because of the design of the POTW, it is
not possible to either sample or directly measure the
flow of the raw plant influent prior to the addition of
sidestreams. This is because one of the two main lines
that carry wastewater into the plant has several side
streams added before the two lines join. Therefore, it is
necessary to sample the outfalls separately and composite
the samples on the basis of the ratio of flows of the
outfalls. We can make allowances for the sidestreams ef-
fect on flow although some precision may be lost. The
sidestreams are: the return from the flow equalization
basin, the sanitary sewer for the POTW operations build-
ing (which includes laboratory waste and domestic type
waste), the return lines for the plant samplers, super-
natant fluid from the digestor, septage and the lime
slurry feed line. Except for the flow equalization basin
return, these are all relatively small flows and may not
change the influent volume so much as to invalidate the
measurement.
2) Discharge: This can be measured when the Dissolved Air
Flotation (DAF) of the waste activated sludge is in use.
DAF is used to thicken the waste activated sludge before
digestion. When the DAF is not in use, the wasted ac-
tivated sludge and the primary clarifier sludge are com-
bined prior to any monitoring points. The scum pit also
discharges to the primary sludge line. Due to the design
of the equipment, the DAF is only usable during warm dry
weather.
3) Primary effluent: As for sampling # 2, above.
4) Sludge to disposal: No problem. This is constantly
monitored.

5) Aerobically digested sludge: Does not exist. Sludge is
not subjected -to aerobic digestion prior to disposal.
E SIU.monitoring, SIU monitoring shall be as required•in
the permits as approved by the division.
F Septage Septage is discharged and measured at one fixed
point in the_•�,system. It is then pumped into the head-
works.

complete, three of the four downstream points have only
data for the middle six months of the year; April through
October. However, this sampling has been conducted since
1986. Therefore, I propose to do the minimum amount of
sampling required by the state. From July to August, and
in October, I plan to collect one sample per month at
upstream monitoring point and downstream point .
During September we will collect one sample each week
during the first and third weeks.

Even if 18 were also considered
an outlier, the mult. factor
would be 1.9, predicting a
maximum concentration of 27
µg/1 with 58 data points. These
results are borderline at best;
therefore a lead limit is
recommended for renewal.

Dear Mr. Goodrich:
Subject: Request for Minor Permit Modification for Cyanide and Supplemental
Information for Permit Renewal
City of High Point, Westside Wastewater Treatment Plant (WWTP)
NPDES Permit NC0024228
Davidson County
The purpose of this letter is to request an immediate minor modification to the existing
permit to include a quantitation level for cyanide. This letter also provides additional
information for the permit renewal application submitted previously.
Cyanide
The City of High Point is requesting that a quantitation level of 10 µg/L for cyanide be
included in the NPDES permit for the Westside WWTP. We understand that the Division
of Water Quality has determined that 10 ug/L is an appropriate quantitation level for
cyanide for compliance purposes unless specific studies are conducted to develop an
alternative quantitation level. It is also our understanding that all cyanide values less than

this quantitation level would be reported and averaged as zero for compliance monitoring
purposes.
Based on previous discussions with your staff, this addition of a quantitation level is
considered a minor permit modification. Therefore, we have included a check in the
amount of $100 in accordance with 15A NCAC 2H .0105 (b) (1) (D).
The City of High Point also submitted a letter on April 23,1997, requesting a minor
modification to convert the daily cyanide limit into a weekly average for both the Eastside
and Westside WWTPs. A check in the amount of $200 was submitted on May 30,1997, for
these minor modifications. The permits have not been modified. Please let us know if we
need to resubmit this request, or if the previously submitted fees could be applied to the
requested minor permit modification.
Supplemental Information for Permit Renewal
A permit renewal application was submitted for this facility on January 21,1998. After this
permit application was submitted, reasonable potential to exceed (RPE) values were
calculated for effluent metals concentrations for the period of July 1,1995, through June 30,
1998. The RPE calculation is based on EPA's Technical Support Document for Water Quality -
Based Toxics Control, Table E-1, Daily Maximum Permit Limit Calculation. One of two
calculations were used based on the dataset; either for some measurements less than the
detection level or for all measurements greater than the detection level. RPE values were
calculated for the 99th percentile and compared against daily maximum permit limits. If the
RPE value is less than the permit limit for a particular metal, then the City of High Point
feels that there is no reasonable potential to exceed the permit limit or action level and
requests that monitoring for that metal be discontinued. The results of the calculation are
summarized in Table 1. The complete data set is presented in Attachment A.
The metals with permit limits greater than the 99th percentile RPE include:
• Cadmium
• Chromium
• Nickel
• Lead
Therefore, the City of High Point requests that this analysis be considered during the permit
renewal and that permit limits and monitoring requirements for these metals be dropped
from the NPDES permit when the permit is reissued.

NORTH CAROLINA DEPARTMENT OF

July 14, 1998
Subject: "April 1998 DMR Data Qualification"
Dear Mr. Frazier
The "April 1998 DMR Data Qualification" summary submitted to -our office on June 1,
1998 contained information on research samples and other compliance samples analyzed for
your laboratory. The samples submitted to the UNC - Chapel Hill lab for analysis can not be
reported, they are analyzed by a laboratory that is not currently certified through 15A NCAC
2H .0800. The submission of this information as part of an "April 1998 DMR Qualification"
was, and is, unnecessary. The samples submitted to a "contract" lab and analyzed properly
must always be reported.
In several cases, sample data reported to the State of North Carolina on Discharge
Monitoring Report "Qualifications" is misleading. While the Laboratory Certification Section is
aware of many ongoing studies, we do not see the need for confusion if the lab is clearly
identifying the samples sent to its "contract" lab. The information supplied concerning
improperly cooled samples sent to the "contract" lab is also unnecessary. The rules of the
State of North Carolina indicate:
When a laboratory receives samples which do not meet sample collection, holding
time, or preservation requirements, the laboratory must notify the sample collector or
client and secure another sample if possible. Reference: 15A NCAC 2H .0805 (a) (7)
(N).
A copy of the April DMR indicates that a substitute sample was indeed reported on
the 24th of April. The information provided was unnecessary. Your letter of June 19, 1998
indicates that "the contractor retumed results to us in the package of data on other
compliance samples". This data should have been qualified:
When a laboratory receives samples which do not meet sample collection, holding
time, or preservation requirements, the laboratory must notify the sample collector or
client and secure another sample if possible. If another sample cannot be secured,
the original sample may be analyzed but the results reported must be qualified with
the nature of the infraction(s) and the laboratory must notify the State Laboratory
about the infraction(s). The notification must include a statement indicating corrective
actions taken to prevent the problem for future samples. Reference: 15A NCAC 2H
.0805 (a) (7) (N).

It is our recommendation that you use the "Data Qualification" format only for data provided on the
DMR's and avoid further problems by clearly identifying all samples on a record or "chain of custody" as
"research. The reports to your laboratory from your contract lab may then be traced properly. With
proper documentation, confusion can be avoided at the time of audits, and information supplied to the
State of North Carolina will not be clouded by "study" sample results.
Thank you for your cooperation. If you require additional information, please contact us at 919-

RE: Response to June 8th 1998 Problems with April 1998 Data Qualification Letter
°2X1Y11)
DWQ
LABORATORY SECTION
Dear Mrs. Brower:
The samples identified in our letter for April 13 and April 23, 1998 were collected for the purpose of an
on -going research project being conducted by the researchers at UNC-Chapel Hill through the Urban
Water Consortium of the UNC WRRI. They were never intended to be compliance samples. I believe the
DWQ Laboratory Section has also participated in portions of this project. Please contact Dr. Robert
Holman at WRRI at [phone] if you have questions regarding the research project.
One aspect of the research project being investigated is the effect of refrigeration of samples on cyanide
samples analyzed according to different methods. Split, grab samples were collected by Mr. Steve Cook
of UNC and myself. One of the split samples for the effluent was submitted to our contractor (ATEL) for
cyanide analysis without all of the necessary refrigeration requirements. These results will be compared
with those being done at UNC as part of the research. These samples were not intended to be compliance
samples; therefore the typical records for field collection of compliance samples were not maintained. The
primary reason the data was reported in the qualified format is that the contractor returned results to us in
the package of data on other compliance samples. We were concerned that this documentation might
create confusion during future audits if this data was not included on the DMRs. In addition we felt the
result should be forwarded in a qualified format because it was in our possession.
We clearly recognize the requirements of 15A NCAC 2B .0506(b)(3)(J); however, we do not think this
applies to a situation where a sample was being purposely collected and handled in conflict with 40 CFR
136 requirements for the purpose of research. We recognize that our letter of May 26, 1998 was not clear
in this regard. If you have any suggestions regarding how future samples related to method research being
done by another organization should be handled and reported, please let us know.
As part of the same research project, UNC has requested our assistance with the collection of additional
split samples for analysis by our contractor and UNC. Because this aspect of the project does not relate to
sample temperature requirements, the split samples we collect for this event and forward to our contractor
will fully comply with handling requirements in accordance with 40 CFR 136. Therefore, our half of the
split samples will be considered as compliance samples in this instance. -

Telephone [phone] FAX [phone] TDD [phone]

Hopefully, this clarifies the situation involving the April samples. We understand the requirements in
your rules and are trying to comply. However, we do not feel it is appropriate to report results from our
analyses that were specifically collected to examine methods that are not approved on the DMR. Any
guidance from DWQ regarding how to approach this issue would be greatly appreciated. Thank you.
Sincerely,
William D. Frazier

Analytical Quality Control
1. BOD Anomalies:
GGA - did not meet criteria for samples of April Pt and 30th. All other criteria were
acceptable with the exception of the 30th (see explanation below).
Palyseed - did not meet criteria for samples dated April 13'h, 14'h, 22nd and 30`h. All other criteria
were acceptable with the exception of the 30`h (see explanation below).
Dilution water blanks — did not meet criteria for samples dated April 29th and 30th. All other
criteria were acceptable with the exception of the 30th (see explanation below).
April 30th — All BOD analyses were unacceptable. Dissolved oxygen consumption was 100% in
all samples and QC. We believe that our water system has been stressed since the feed water
disinfection has been changed from free chlorine to a combination of chlorine and ammonia. This
occurrence was during the time the process was in transition. Ammonia and Nitrate -Nitrite
analyses did not reveal any striking differences in the water provided by the deionized system but
the readings were elevated above the norm.
We have contracted with a third party contractor to troubleshoot the system and have
already found that the RO membranes are experiencing premature failure due to chlorine stress.
We are going to try to place an oversized carbon unit at the end of the process but have been told
that it will have limited effectiveness against total chlorine products such as chloramines if other
system components do not operate properly.
Further, once we noted this problem, we began sending BOD samples out to Water
Technologies and Controls (WT&C) to avoid any further invalid results. May will have
approximately 10 days of data for BOD that will be averages of ours and WT&C BOD's.
( 3. Cyanide Research April 13'h Effluent for both plants — Mr. Steve Cook (Graduate Assistant — UNC
Chapel Hill) visited our plants concerning continuing research through the Water Resources Research
Institute. These samples were cooled but temperature during transport and storage was not recorded
violating 40 CFR 136 and NCDWQ Certification requirements. Both values were 10 ppb. They were
not intended for compliance purposes and subsequent samples taken on the 9`h and 17`h satisfy the
monitoring requirement. Therefore, there is no effect on monitoring or discharge compliance.
4. April 9th & 10`h —No COD analyses were not set up due to a conflict with holding times during the
Easter Holiday. This is a voluntary parameter and does not effect compliance.

RE: April 1998 DMR Data Qualification
Dear Mr. Meyer:
The following situations were encountered during the monitoring period covered by the Discharge
monitoring Report noted above:
NC0081256: Ward Filter Plant Lagoon
1. none
NC0024210: Eastside POTW
1. Apri123`d — Eastside Effluent CN sample was delivered to the Central Lab without proper
refrigeration. As part of our ongoing research, we forwarded the sample to the contract lab to
determine what effect no cooling would have. The result was 11 ppm but was not reported on the
DMR due to noncompliance with 40 CFR 136 requirements. A substitute sample was taken on the 24th
therefore; there was no violation of monitoring requirements.
NC0024228: Westside POTW
1. April 17th — The initial DO taken around 8:00 in the morning was below the permit limit of 6.0 ppb
due to a flooding event. These events cause surcharge into the effluent pipe where the measurement is
made. This does not accurately reflect effluent conditions but rather conditions of upstream water.
Operations staff performed DO measurements after the water receded that would have brought the
plant back within compliance but the measurement occurred on the following calendar day. However
it was within the 24-hour compositing period. We have consulted with the NCDENR Division of
Water Quality office in Winston-Salem requesting a ruling conceming the averaging of data for
compliance purposes. Until that ruling, we wish to exercise the ability to delay a determination of
compliance on this parameter. This will also affect the data for the 18t. Subsequent measurements
intended for the 17t were averaged with the 18`h and reported on the DMR.
2. April 29th — Influent COD exceeded the upper limit of calibration. The value read was 10'20 ppm and
the upper limit is 1000 ppm. Sample had been discarded and could not be rerun. This represents an
extreme condition for influent quality and an unexpected anomaly for analytical performance.
Samples are now being preserved and held until the next business day to avoid future occurrences.

The following situations were encountered during the monitoring period covered by the Discharge
monitoring Report noted above:
NC0081256: Ward Filter Plant Laeoon
1. none
NC0024210: Eastside POTW
1. December 1" — Influent sample received @ 0°C and contained ice. Sample bottle was placed in freezer
prior to introducing sample. Residual wash water froze. Samplers were instructed to refrain from pre -
freezing bottles. NCDWQ, Brower notified by FAX on December 3rd
NC0024228: Westside POTW
1. December 23rd — Contract lab supplied bottles either did not contain preservative or the preservative
was poured out during sampling for mercury. Sample was returned to the Central Lab within
acceptable holding times and preserved. Contract lab and POTW personnel were asked to observe
bottle conditions prior to adding sample in the future. POTW will request new bottles if the condition
is observed again.

1. BOD Anamolies:
(a) BOD Blanks >0.2 ppm DO uptake — December 11 & 22
(b) BOD Seed uptake <0.6 or >1.0 ppm uptake — December 24
(c) BOD GGA not within SM 18t ed. control - December 1, 2, 5, 29& 30
2.. December 5th — COD digester temperature, and digestion times were not documented on the
worksheet. COD is a voluntary analyte on the permit and does not affect compliance with DMR

3. December 12th — Commercial Carrier accidentally diverted The Eastside and Westside cyanide sample
sent to contract Lab on ice. They arrived at the contract lab several days later with the ice had melted
and at 12°C. Samples were analyzed and reported. We have made an agreement with our contractors to
either deliver or have them pick up samples avoiding commercial carriers altogether.
BOD QC deviancies - we discussed properties we encountered with deionized water system use
for BOD and toxicity makeup water in last month's qualification letter. Most of the problems were
solved. The intermittent problems that are occurring are due to system maintenance we cannot
perform and have not been able to solicit a response from our system contractor. They claim a
Shortages in qualified personnel but are addressing the problem.
System maintenance was performed on January 24t. We will keep you up to date with further
developments on our progress

Page 2 of this FAX contains information concerning further BOD discoveries we have made as we continue to
improve our section's technique: (A) We discovered that the habit of calculating out all BODs (including those
that did not meet criteria for one reason or another) and giving the worksheet to people that do not understand
the criteria lead to a false interpretation and lower numbers generated. This effected surcharge costs and
created a controversy that spread to the WSRO DWQ office. This is just for general interest. (B) We are seeing
the possibility of a very strange effect of sore throats progressing into strep for those working in and around
the BOD section. The only things that have absolutely changed are the location, source of seed (polysecd) and
makeup water source (RO + Mi1liQ). People that have worked in the section have contracted this and the
others in the lab seem immune. Do you have any thoughts?
In response to you questions of March 25 requesting further information for GGA out of specified limits:
(a) GGA was outside of the 198±30.5 for 2 days. The values were 238 ppm and 148 ppm BOD
respectively.
(b) Other QC:
(i) Dilution water Blanks = All <0,2 ppm DO uptake for 5 days
(11) Seed Correction Check = All 0.6 to 1.0 ppm DO uptake for 5 days
(ii i) Duplicate % difference = <10%
(e) Sccondfiry Source Standard = not performed within this group of samples.
The COD samples were held less than 2 hours and were refrigerated during the entire time. The question
was not quite clear though. On the two or three days that are in question, the calibration standards,
duplicates and spikes were out of control limits. As stated above, the were preserved according to
requirements and rerun at a later date. This question did not constitute samples that would not have meet
all of the required preservation and holding times as well as the QC for daily calibration, precision and
accuracy. A "heads up" call on the part of the analyst in training saved us by doing the right thing versus
the routine. We just though we would save time and a future letter by getting an answer now instead of
later.

OFFICE OF
WATER
Dear Dr. Frazier:
This letter responds to your letter dated November 20, 1996, concerning
determination of cyanide at the City of High Point's publicly -owned treatment works.
It is very difficult to discern the exact nature of the cyanide interference problem and
to recommend a solution from the data enclosed with your letter. The primary reason is the
nature of the quality control (QC) data,
Enclosed you will find a diskette containing documents that describe EPA's
streamlining initiative. Chapter 2 of the document titled Guide to Method Flexibility and
Approval of EPA Water Methods (the Streamlining Guide) describes standardized QC that
EPA is recommending for use with all methods. This QC includes an initial demonstration
of laboratory performance and analysis of a blank, laboratory control sample, a matrix spike
(MS), and matrix spike duplicate (MSD) with each sample batch. These QC tcsts allow an
assessment of laboratory performance and an assessment of application of the analytical
procedure to the sample matrix.
The MS and MSD are especially important in dealing with matrix problems, such as
those you may be encountering, because spike recoveries and precision are indications of
how well the method and laboratory perform in the analysis of a particular sample.
We suggest that you review the appropriate sections of the Streamlining Guide, have
the laboratory perform the standardized QC tests recommended therein, and review the data
for possible matrix interference problems. If you believe that the data from the standardized
QC tests support that matrix interferences prevent reliable determination of cyanide in the
samples tested, please submit the data from the standardized QC tests. Once submitted we
will review these data to determine if there are additional measures that should be taken to
resolve the interferences.
Regarding the control limits described in the postscript to your letter and for which
tables of data were provided, EPA believes that such control limits are a valuable tool for
determining that the analytical system remains under control. However, in those instances in

which an analytical method contains QC acceptance criteria (e.g., Method 624), the control
limits should not be allowed to exceed these criteria and results outside of the QC acceptance
criteria in approved EPA methods should be considered noncompliant.
Additionally, EPA is participating in the development of two new cyanide methods
that are less susceptible to interferences than the existing 40 CFR part 136 methods .
Method 1677 for the determination of free and weak acid dissociable cyanides in water and
wastewater by flow injection and ligand exchange will be proposed in the Federal Register
within the next couple of months, and Method 1678 for the determination of total cyanide in
water and wastewater is presently being drafted. These methods will be available shortly and
hopefully will alleviate your interference problems
If you have questions about the streamlining initiative or need assistance in accessing
the files on the enclosed disk, please contact the EPA Sample Control Center at 703/519-
1140. If you have questions regarding this letter, please write or call (202/260-7120) as
convenient.

We received a letter from the group monitoring our compliance with the American Canoe Association's consent
decree requesting that we pay additional money for August 1997 (attachment #1). Their contention is that violating
holding times due to legal holiday vacation time granted by the government employers does not constitute a valid
defense. .
You will also find an attached copy of the City's Personnel Ordinance, page 16, Article F. Holidays and Leave
(#2). It describes the 8 vacation days that we are allowed and how they are applied. The Christmas vacation period
might be extended relative to the day on which it fails; such as this year. Since Christmas falls on a Thursday, we
will be granted Wednesday the 246, Christmas Day and Friday the 26th for vacation. We will return to work on
December 29th. BOD samples will have violated their 48 hour holding times.
We will perform the analyses, report the data on the DMR and include the appropriate qualifier as we have
formerly agreed but this does not prevent the ACA from demanding reparation under the Consent Agreement.
They have indicated that they are willing to apply the State's judgements on these matters and not exceed that
authority. It.wouid be greatly appreciated if you could provide us with a clarification to submit to therm concerning
our procedures for holiday conditions.
Your speedy response to this request is appreciated as well as very important relative to further payments. •
According to the agreement, we have 10 business days to respond to their request or be subject to other financial
obligations. Thank you.

Addendum to: NCDEH R Division of Water Quality
APPLICAITON FOR WASTEWATER ANALYTICAL LABORATORY CERIIFICATION
Section V. Quality Control Program, 40 CFR 136 Sampling Requirements
STANDARD OPERATING PROCEDURES FOR SAMPLING
REVISED: December 1996
(latest revisions in bold italics)
GENERAL SAMPLING REQUIREMENTS
INTRODUCTION: All samples taken under the jurisdiction of the City of High Point Central Laboratory
Service's NCDEHNR Division of Water Quality Certificate #55 wiIl be performed according to the
appropriate regulatory requirements (40 CFR 136, 18th Edition Standard Methods, USEPA 600 series
methods (when there are no other applicable methods from 18th SM) and supplements. It is ultimately the
responsibility of the Laboratory Supervisor to apply this guidance. Any deviations from these
requirements may render the data invalid and could result in decertification and/or criminal penalties for the
lab.
A. Sampling Techniques
Sample must be taken at the designated locations. They were developed with
consideration given to relevant factors such as safety, mixing zones, occlusion of bottom
sediments, floatables, etc. All sampling equipment for collecting,composite samples
used to determine compliance and requiring refrigeration per 40 CFR 136 Table II
must be maintained at 1-4.40C measured with a calibrated thermometer in a water -
based surrogate sample. Temperatures must be checked and recorded applying the
temperature correction factor from the thermometer label at the time of the
)° C/measurement. The thermometer must have been calibrated against a MST
standard thermometer. A log must be maintained that indicates the number
assigned to the thermometer by the Central Lab at the time of calibration. The
following steps should be used as a general guideline:
1) All samples must be homogeneous. When a larger sample container is used, mix
sample by shaking, swirling, or mechanical mixing thoroughly before decanting or
splitting sample into other bottles. NOTE: mechanical mixing is the least preferred
since it is the most likely to introduce the possibility of contamination. However,
samples may be homogenized in the lab under specific conditions. It is the
responsibility of the QC Officer to make sure it is properly homogenized
2) Sample bottles that contain a preservative (acid, base, declorinating agent, etc)
will be labeled with a Central Lab HazCom label (fluorescent pink) designating
the type of preservative, hazards and any personal protective equipment
required The chain of custody will also include specific information to
designate this sample. Do not rinse the sample bottle with sample and pour out if
sample bottle contains preservative. For further detail concerning safety labeling,
please see the Central Laboratory Services Laboratory Standard HazCom document.
3) If proper cleaning is in question or bottle is not completely dry when ready to use,

1
permit, or license criteria. These violations will be noted by taking the worksheet out
of the normal train of review, explaining the reason for the violation on the
worksheet, and submitting the worksheet will be given to either the Lab Supervisor,
Analytical Chemist or senior QC Officer (Chemical Analyst III) in their absence
where it will be held until the violation is noted on the Analytical Quality Control b
Data Invalidation (AQCDI) letter (Oakley, Aug. 1996). Any sample which is
reported for compliance purposes and does not meet all of the above requirements
will be invalidated Notification will be forwarded in letter to the NCD WQ
Certification Section monthly as required and included with the DMR reports to
their respective agencies listed in #7 below.
6. Sampling points which have multiple locations (such as POTW effluent) must be
designated on the DMR as to the exact location where the sample or data is generated.
7. FORWARDING REPORTS TO SPECIFIED AGENCIES - all reports
will be forwarded to the required agency as described below on the approved form
according to the applicable regulatory requirement If certified mail is not an
option offered (such as the primary mailing address listed is a post office box), a
certified mail copy will follow the required mailing. In-house copies will be sent
through interoffice maiL
For certified mail, reports are given to Office Support, placed in a Certified Mail
Envelope, logged with the date it is processed, what report is being mailed, to whom
it is being sent and the person that is mailing the document. Upon return of the
signed receipt, it is logged the day Office Support receives the signed receipt, and
kept in the Certified Mail Envelope for future reference.
A) The primary copy of NPDES Division Monitoring Report (DMR) for Eastside,
Westside POTW, and Ward Plant Lagoon must be mailed by the last day of the
month following the period covered.

Subject: Wastewater/Groundwater Laboratory Certification
Dear Mr. Frazier:
In June 1996, the High Point Wastewater Laboratory began using an "alternate reporting
format" consisting of an attachment to the monthly DMR This attachment is a listing of
problems that occurred during sample processing and analysis that resulted in qualified
analytical results. To date, each of the monthly reports have included a long list of
problems which we believe are excessive. As stated in Mr. Oakley's letter dated
August 9, 1996, it is the responsibility of your facilities to correct these problems. The
alternate reporting format does not relieve the responsibility to correct violations of State
Rules.
We have divided the problems you reported into three categories listed below:
1. Some of the problems listed related to sample collection and wastewater
plant operations. In the Division of Water Quality, these come
administratively under the Winston Salem Regional Office.
2. Some of the problems seem to be requirements that are internal to High
Point Facilities and it is questionable to use these to qualify data. Examples
of this are departure times of samples and incomplete chain of custody
signatures. Our certification program does not require chain of custody
signatures.
3. Some of the problems listed are violations of the certification program
requirements and are a concern to us. Attached is a listing of these
violations taken from your monthly lists. The BOD/GGA violations have
been summarized as they relate to the same problem. We request that your
laboratory take corrective actions to prevent these from reoccurring. We

cannot maintain your certification if your laboratory does not meet
certification requirements in its daily operations. If these violations
continue to occur. we may recommend enforcement actions.
Many of the problems listed are correctable mistakes. High Point staff members can enter
missing times, initials, etc. if they are known. Whenever there is a problem with an
analytical parameter that has a long holding time, the problem must be resolved and the
samples reanalyzed to get an acceptable result. Examples of these parameters are metals
and C.O.D.
The lists you provide includes references to duplicate results that exceeded t 25% as
unacceptable. As we advised you earlier, the use off 25% as an acceptance criteria may
not be acceptable. The only time it is acceptable is when the 25% is equal to or less than
three standard deviations of the range based on statistical calculations from your data or
the acceptance criteria set forth in the analytical method. For some samples with
extremely low values, ± 25% may be difficult or impossible to achieve on a daily basis.
Prior to the November 1992 revisions, the certification Rules included a regulatory
acceptance limit off 25% for analytical data. The revised Rules deleted the f 25% and
adopted a 99% confidence interval or three standard deviations as acceptance criteria.
Some analytical methods include acceptance criteria that may be used.
We are aware that you subcontracted BOD analyses while correcting analytical problems.
In addition, we are pleased that the list of deviations in October had decreased from
previous months. It is our hope that future reports will show a decrease in the number of
problems.
Contact us at 919-733-3908 if you have questions.
Sincerely,
C.4-0-1-4,A,

Dear Permittee:
NC DENR
November 2, 1998
Subject: Modification of NPDES Permit NC0024228
West Side WWTP
Davidson County
The Division is beginning the second five-year cycle of river basin planning and permit renewals. An
examination of the basin planning schedule has revealed that the tuning of permit renewals does not
allow an evenly distributed workload as first envisioned. This results in problems with the efficiency
and effectiveness of the NPDES program. In an effort improve customer service, and after thorough
review of the water quality issues in your area, the Division is changing the permit renewal schedule for
all NPDES permits in your sub -basin.
This permit modification changes the expiration date of the subject permit to April 30, 1999. Please
find enclosed the revised permit cover page. Insert the new cover page into your permit and discard the
old page. All other terms and conditions contained in the original permit remain unchanged and in full
effect. This permit modification is issued pursuant to the requirements of North Carolina General
Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U. S.
Environmental Protection Agency.
If you have already submitted a permit renewal application for the subject facility, the Division will
retain the application until your permit is due for renewal. No additional forms or fees will be required.
If any parts, measurement frequencies or sampling requirements contained in this permit modification
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 a written petition conforming to
Chapter 150B of the North Carolina General Statutes, filed with the Office of Administrative Hearings,
Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this
decision shall be final and binding.
If you have questions about this modification, please contact Charles Weaver of my staff at the
telephone number or address listed below.

Subject: Status of NPDES Permit NC0024228
West Side WWTP
Davidson County
After a thorough review of the Yadkin -Pee Dee River basin management plan and water quality issues relevant to
the subject facility, the Division of Water Quality has decided to extend the duration of the subject permit. The
expiration date of your permit will be changed in order to allow the Division to review all NPDES discharge
permits in the Yadkin River Basin during calendar year 1999.
All terms and conditions in the existing permit will apply until a new expiration date is assigned by the Division.
Extension of existing Effluent Limitations and Monitoring Requirements does not exempt the subject facility from
the new Enforcement Policy recently enacted by the Division.
Attached to this letter is a copy of the Public Notice that is being published to announce the planned extension of
your permit. After Public Notice has been made by the Division, the expiration date of your permit will be changed
via a permit modification. No draft permit will be sent out with the Public Notice, as none of the conditions in the
existing permit will be modified.
If you have already submitted your renewal application package, no additional fees or documentation will be
required as a result of this change to your permit's expiration date. If the Division has not yet received a renewal
application for the subject permit, you will find the necessary application form(s) attached to this letter.
The Division appreciates your patience and understanding to date regarding the rescheduling of the subject
permit. If you have questions about this proposed modification or about the permit renewal process, contact
Charles Weaver of my staff at the telephone number or address listed below.

PURPOSE: The facilities listed above all discharge into the Yadkin River basin. Other permits in the
Yadkin River basin have expiration dates in calendar year 1999. The facilities listed above
have permit expiration dates in 1998. In order for the Division to evaluate all permit
renewal requests in the Yadkin River basin during the same calendar year, the Division
plans to extend the expiration dates of the permits for the facilities listed above. No
conditions in the existing permits will be changed or modified. This is an administrative
change to better align permitting and Basinwide Planning operations within the
Division of Water Quality. On the basis of preliminary staff review of Article 21 of
Chapter 143, General Statutes of North Carolina (and other lawful standards and
regulations), the North Carolina Environmental Management Commission proposes to
extend the duration of the NPDES permits listed above, subject to specific pollutant
limitations and special conditions.
INFORMATION: A copy of the existing NPDES permits and a sketch showing the location of each
discharge is available by writing or calling.
