Dear Mr. Hudson:
Michael F. Easley

William G. Ross, Jr., Secretary
North Carolina Department of Environment and Natural Resources
Kerr T. Stevens, Director
Division of Water Quality
January 29, 2001
Subject: Issuance of NPDES Permit NC0031836
Fourth Creek WWTP
Iredell County
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended).
2000:
The following changes were made to the final permit in response to your comment letter of December 19,
> The limit for Nickel has been deleted (both 4.0 and 6.0 MGD) in the permit renewal. Reasonable Potential
Analysis indicated that the maximum predicted level of Nickel was less than the allowable concentration.
> Mercury monitoring has been deleted (both 4.0 and 6.0 MGD). One year of discharge monitoring data
indicated levels below the detection limit.
➢ Fecal Coliform and Conductivity instream monitoring requirements have been deleted.
> The weekly average limit for Cadmium (4.0 MGD flow) was revised from 5.5 to 4.4 µg/L. The reasonable
potential analysis indicated that a more restrictive limit is necessary. In addition, the daily maximum limit
was revised from 13.9 to 15 µg/L as per current Division policy.
> The weekly average limit for Lead (4.0 MGD flow) was revised from 69 to 55.2 µg/L. The reasonable
potential analysis indicated that a more restrictive limit is necessary. In addition, the daily max limit was
revised from 94 to 33.8 µg/L as per current Division policy.
> A limit for Chromium was added to the permit renewal for both flows (4.0 and 6.0 MGD). The reasonable
potential analysis indicates that the maximum predicted level for this parameter is greater than the allowable
concentration. Therefore, a limit was included in the final permit. The Division suggests that the facility use
a consistent quantitation level for this parameter. The past monitoring data was highly variable due to the
fact that two quantitation levels were reported. The facility may request that this limit be dropped after one
year of monitoring data is collected that shows levels below the detection limit.
> A limit for total residual chlorine (TRC) was added for the 6.0 MGD flow. Division policy requires a limit
for TRC for all new flow.
> A cyanide limit was inadvertently placed in the draft permit. We apologize for this mistake and have
removed the limit from this final permit.
➢ Monitoring for Total Nitrogen and Total Phosphorus has been changed to weekly. The results of this
additional monitoring will be used in the development of a nutrient management strategy for the Yadkin
River Basin.
➢ The limits for ammonia nitrogen were inadvertently changed in the draft permit. We apologize for this
mistake and have reinstated your previous limits.

This letter is to inform you that the Division has finalized its review and the comment period is
now losed for NPDES permit NC0031836. A final copy of the permit is attached to this letter. This
pe it is issued pursuant to the requirements of the North Carolina General Statute 143-215.1 and the
emorandum of Agreement between North Carolina and the US Environmental Protection Agency
ated December 6, 1983.
The following list has been included to outline the changes that were made to the final permit in
onse to your comment letter dated December 19, 2000:
The limit for Nickel has been deleted (both 4.0 and 6.0 MGD) in the permit renewal. The
Reasonable Potential Analysis indicated that the max predicted level for this parameter is less than
the allowable concentration. Therefore, a limit for this parameter is no longer necessary.
> The monitoring requirement for Mercury has been deleted (both 4.0 and 6.0 MGD). One year of
discharge monitoring data indicates levels are below detection.
> Fecal Coliform and Conductivity instream monitoring requirements have been deleted. Division
policy does not require monitoring for these parameters.
> The weekly average limit for Cadmium (4.0 MGD flow) was revised from 5.5 to 4.4 ug/l. The
reasonable potential analysis indicates that a more restrictive limit is necessary. In addition the daily
max limit was revised from 13.9 to 15 ug/1 as per current Division policy.
> The weekly average limit for Lead (4.0 MGD flow) was revised from 69 to 55.2 ug/l. The
reasonable potential analysis indicates that a more restrictive limit is necessary. In addition the daily
max limit was revised from 94 to 33.8 ug/1 as per current Division policy.
> A limit for Chromium was added to the permit renewal for both flows (4.0 and 6.0 MGD). The

Dear Mr. Weaver:
JAN 7 2 2Oui
DENR - WATER
Q
POINT SOURCE BR/UCH
Per our conversation yesterday I am submitting to you our concerns with the referenced
permits. These comments are a result of my conversation with you as well as a
conversation Ms. Carol Rogers, Pretreatment Coordinator, had with Mr. Joe Corporone.
Fourth Creek WWTP
Permit No. NC0031836
1. Ammonia. We have a concern with the proposed ammonia limits. This is a
drastic reduction. No reason for this reduction was given. Mr. Corporone
advised Ms. Rogers that these limits appeared to be in error and that the old
limits would be reinstated. We would request the old limits be reinstated.
2. Cadmium. We believe the weekly limit proposed for Cadmium under the
6-MGD permit to be too low to achieve compliance. We request a higher
limit.
3. Cyanide. The limit for Cyanide is too low. Mr. Corporone recalculated
this and told Ms. Rogers an error had been made. After Mr. Corporone
had a discussion with Mr. Dave Goodrich, Mr. Corporone informed Ms.
Rogers that the Cyanide limits would be dropped from the new permit.
We request this to be reflected in the new permit.
4. Chromium. Chromium has been added to the new permit. We question
this as our data shows we are consistently below detectable limits. We

Page 2
NCDENR/Raleigh
Re: Draft Permits
December 19, 2000
request that no Chromium limit be placed in the new permits, both 4 MGD and 6 MGD.
Third Creek WWTP
Permit No. NC0020591
1. Ammonia. We received the same information as that above regarding the
ammonia for Fourth Creek WWTP. We request the old limits be reinstated.
We appreciate your consideration in this matter and look forward to discussing this with
you at your convenience.
Sincerely,
L. F. "Joe" Hudson, Jr., Director

Summary
The facility has requested a permit renewal with no modifications.
The following notes were taken during the review of the application package:
> Review of Basin Plan:
Fecal coliform levels in Third and Fourth Creeks are high upstream of
Statesville's dischargers, indicating that non -point source runoff
contamination is the probable source although several small facilities in the
subbasin show occasional violations.
The two largest of these major facilities are Statesville's third and Fourth
Creek WWTPs. No instream DO violations were reported by Statesville's
Fourth Creek WWTP in its self monitoring reports during 1992-1996. There
is, however, a measurable decrease in DO concentrations below the
discharge.
DWQ intends to develop NPS management strategies for this waterbody for
the second Yadkin -Pee Dee River Basin Plan. In addition, local efforts are
needed to develop a plan to reduce non -point source pollution.
> 303(d) List Review
Reported problem parameters include sediment, Fecal Coliform and
turbidity.
> Reasonable Potential Analysis:
A reasonable potential analysis was performed using the most recent DMR data.
The results of the analysis are attached to this document. In summary,
- Cadmium The maximum predicted concentration was determined to
be greater than the allowable concentration. Therefore, a limit of 4.4
µg/1 was be included in the renewal
Cyanide The maximum predicted concentration was determined to
be greater than the allowable concentration. Therefore, a limit of 0.1
µg/1 was be included in the renewal.

DENR/DWQ
FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NC0031836
(Continued)
- Lead The maximum predicted concentration was determined to be
greater than the allowable concentration. Therefore, a limit of
55.2141 was be included in the renewal
Nickel The maximum predicted concentration was determined to be
less than the allowable concentration. Therefore, no limit will be
included in the renewal.
Chromium The maximum predicted concentration was determined
to be greater than the allowable concentration. Therefore, a limit of
110.4 µg/1 was be included in the renewal.
- Copper Monitoring only for copper will be included in the permit.
This parameter has an action level of 7 µg/1.
- Silver Monitoring only for silver will be included in the permit. This
parameter has an action level of 0.06 mil.
Mercury One year of mercury monitoring data was submitted in a
letter dated September 19, 2000. This letter indicated that mercury
levels were all below a detection level of 0.2 µg/1. Therefore, no
mercury monitoring requirements were included in the permit
renewal.
Zinc Monitoring only for zinc will be included in the permit. This
parameter has an action level of 50 µg/1.
The facility joined the Yadkin Pee -Dee River Basin Association as of June 1,
1998. Therefore, the established instream monitoring requirements will be
waived until the facility chooses to end its membership with the association.
• WLA Review:
The most recent WLA was prepared in July of 1994. Limits were determined
to be water quality limited and instream monitoring was
recommended for DO, Fecal Coliform, Temperature, and Conductivity. In
addition, the following metals monitoring requirements were recommended:
Cadmium daily max limit of 5.5 µg/1, Cyanide daily max limit of 14 µg/1;
Nickel daily max limit of 244 µg/1, lead daily max limit of 69 µg/1. Mercury
monitoring and Chromium monitoring.
Note: New USGS flow guidelines caused the 7Q10 estimate to drop from 1 lcfs
to 7.5 cfs. Limits for 6.0 MGD flow were based on the new 7Q10 estimate.
Limits for 4.0 MGD were based on old estimate.

> Staff Report Review
Most recent staff report was prepared in February of 1999. The WWPT
appears to be adequate to meet all existing effluent limits and is well
maintained and operated. The subject WWTP is a member of the Yadkin -
Pee Dee River Basin Association. As a member, all instream monitoring is
conducted by the association. However, influent and effluent sampling
remains under the control of the WWTP facility.
Region recommends that the permit be renewed as requested.

G. 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 36% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perf rm quarterly monitoring using this procedure to establish compliance
with the permit condition. he first test will be performed after thirty days from the effective date
of this permit during the months of January, April, July, 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.

Dear Mr. Goodrich:

A permit modification for reduction in effluent mercury monitoring was requested in October
1998. In response, your Division requested that we monitor mercury with the method
detection limit of 0.2 ug/1 rather than 1.0 ug/1 for at least one year. Please find enclosed the
mercury monitoring conducted from September 1999 through August 2000. We are
resubmitting our request that the effluent mercury monitoring for Fourth Creek be reduced
based on the consistent `below detection level' readings.
If further information is required, please contact Carol Rogers at [phone]. Thank you
for your prompt attention in this matter.
Sincerely,
L. F. "Joe" Hudson, Jr., Director

Re: NPDES Permit Renewal Applications
Third Creek WWTP Permit #NC0020591
Fourth Creek WWTP Permit #NC0031836
Dear Mr. Goodrich:
On January 15, 1999, the City of Statesville submitted a renewal application for the
NPDES permits for our Third and Fourth Creek Plants. Please accept this letter as an
addendum to that application. We would like to present some additional information
which we feel is relevant, but was not included in our original application. This letter is
submitted at the urging of DENR representatives.
We are aware of the monitoring data review conducted by your unit during the
"Reasonable Potential Analysis_" However, we would like to draw your attention to the
following results (Table 1). We would appreciate your consideration on reducing the
monitoring frequency or eliminating these parameters from the new permit.

3rd & 4th Permit Renewals
February 4, 1999
We expect to see continued reductions in these and other metals discharges due to our
participation in EPA's Common Sense Initiative (CSI). The City of Statesville signed
onto this voluntary initiative as a participating municipality in March 1998. In this role,
our pretreatment industries have worked with DENR representatives (from the Divisions
of Water Quality, Waste Management, and Pollution Prevention) and the local metal
finishing community. Under the CSI, we grant regulatory flexibility in our local
pretreatment regulations in exchange for reductions in discharges from the local metal
finishers. To date we have four of eleven metal finishers signed on to this program and
hope to increase this number in the near future.
Should you have additional questions about specific monitoring data, please call me at
[phone]. If you have questions about our involvement in the Common Sense
Initiative please call Greg Newman or Terry Albrecht at the Division of Pollution
Prevention at [phone].
Thank you for your consideration.

Dear Mr. Hudson:

NORTH CAROLINA DEPARTMENT OF

Subject: NPDES Permit Modification
Permit No. NC0031836
Fourth Creek WWTP
Iredell County
A permit modification request and check for $100.00 (#054216) was received by the NPDES Unit on October 15,
1998. This request concerned a reduction in mercury monitoring at the above facility and was based on the
"consistent `below detection level' (<1.0 µg/1) results from October, 1994 through September, 1998."
Unfortunately, the Division cannot consider a reduction in monitoring based on the data submitted. The water
quality standard established in North Carolina for mercury is 0.012 µg/1 (per T15A: NCAC 2B .0200s).
Therefore, at permitted flows of 4.0 and 6.0 MGD, Fourth Creek WWTP's allowable concentrations of mercury
are 0.026 µg/1 and 0.022 µg/l—values that reflect respective instream waste concentrations. The approved EPA
method for mercury`testing, referenced in 40 CFR § 136 (245.1 and 245.2), specifies a quantitation level of 0.2
µg/l.
Data from 1994-95 also indicated that several values were above 0.2 µg/1 but below 1.0 µg/l. Therefore, the
Division cannot justify a reduction in monitoring at this time. The City of Statesville may request another review
of this monitoring requirement after at least twelve (12) months of data are collected with the more appropriate
method, and the results indicate mercury levels are consistently below a quantitation level of 0.2 µg/1.
If you have any questions regarding this modification request, please contact Bethany Bolt at [phone],
extension 551.

NOTES FOR FOURTH CREEK (CITY OF STATESVILLE) WWTP
MODIFICATION REQUEST
Summary:
Modification request to reduce monitoring frequency for mercury. Data submitted was
from 10/94-9/98.
Data since 1996 indicated a method with a detection level (DL) of only 1.0 µg/1 was
used. Most measurements were "<1.0 µg/ 1," which the facility claimed should warrant a
reduction in monitoring to at least quarterly, rather than 2/month now in the permit.
This data was confusing because currently the EPA method referenced in 40 CFR § 136
(245.1 / 245.2) specifies a DL of 0.2 4/1. ?A As r114 D 3 2 7-3 - 9
I contacted Carol Rogers with the City, which had worked with Chet Whiting (?) at MRO
on this, and they decided on a 1.0 µg/ 1 DL, since instruments to measure lower than
that were much more expensive. Rogers said they are still using a state -approved
method and decided this DL is sufficient since there is no limit in the permit.
Otherwise, the facility would have to send the samples out for analysis. I let her know
I'd have to calculate allowable concentrations, but we would most likely be requiring
more data from a test with the lower DL, especially since the water quality standard is
so low.
WLA background notes in '94 documented that updated USGS flow calculation
methods produced a 7Q10 flow estimate of 7.5 cfs, as opposed to the original 11.0 cfs
estimate. Although that resulted in lower allowable effluent toxicant concentrations,
differences did not warrant more stringent limits at permit renewal. Apparently, a
mercury limit had also been proposed back in '92, but it was dropped for monitoring
instead at the request of the facility. (See WLA files for more extensive history; well
organized chronologically from 1982.)
The facility discharges to Fourth Creek, which is classified as C. Based on the more
accurate 7Q10 est. of 7.5 cfs, IWC at 4.0 MGD is 45.3% and at 6.0 MGD, 55.4 %. Since
we assume a background level in the stream of 0 mil of mercury, allowable
concentrations for this facility are:
• 1/0.453 x 0.012 µg/1 = 0.026 4/1 (at 4.0 MGD, 45% IWC)
• 1/0.554 x 0.012 µg/1 = 0.022 µg/1 (at 6.0 MGD, 55% IWC)
These levels are well below 1.0 µg/ 1—and they are below 0.2 µg/ 1. It is even more
puzzling that from 1994-95, levels between 0.2 µg/ 1 and 1.0 µg/ 1 were recorded (what
method was used —it appears to have a DL of 0.10 µg/1...?). So, with allowable
concentrations well under 0.2 µg/1, as well as data indicating it is quite possible that
levels could be above that DL, a reduction in monitoring is not recommended at this
time. The facility should be required to submit at least 12 months of data using the
EPA method with the lower DL before we review this request again.
(At renewal, a DL of 0.2 µg/1 should probably be specified in the permit, as we continue
to be more consistent with other permits that have mercury monitoring.)

Dear Mr. Goodrich:
Plov, /W9g DS�Zi�

j)O�t
The City of Statesville requests a permit modification for reduction in effluent mercury
monitoring. This request is based on the consistent `below detection level' (<1.0 µg/1) resul-is
from October 1994 through September 1998. In an October 20, 1994 permit transmittal let',
the Division stated that the City could request a review of the mercury monitoring requirenlellt as
soon as one year after the effective permit date. The City now requests that the Division conduct
this review and reduce the frequency of effluent mercury monitoring to no more than once per
quarter.
Please find enclosed a summary of the effluent mercury monitoring data and the $100 permit-
modification fee. If further information is required, please contact Renee Parkman at (704) 878-
3438. Thank you for your attention in this matter.

FOURTH CREEK WASTEWATER TREATMENT PLANT
CITY OF SJATESVILLZ
IN_ 111_ II II II III Mt 111 III II

Biosolids Management Plan
The City of Statesville owns and operates two wastewater treatment plants and a water treatment
plant which generate residuals. To manage these residuals, the biosolids management policy is
to process two-thirds of all residuals produced through the NViro process per Distribution Permit
number WQ0006245 and land apply the remaining one-third through a contract operation. The
contract for land application was signed on August 19, 1998 and the contractor is in the process
of obtaining the land application permits. The City also holds Land Application permit number
WQ0014543 which will only be used as a back-up method of residuals disposal. At this time, no
residuals have been land applied. All residuals are being processed through NViro.
The Fourth Creek WWTP processes an average wastewater flow of 2.3 million gallons per day.
After conventional processing through an activated sludge operation, sludge is aerobically
digested and then dewatered using a plate and frame filter press. The press cake is blended with
biosolids from Third Creek and dewatered alum sludge from the water plant. The blended
material is stabilized using the NViro process per Distribution Permit number WQ0006245.
After the contractor has obtained the land application permits, we will begin land applying one-
third of all residuals produced.
