Subject: NPDES Permit Issuance
Permit No. NCO026441
Siler City WWTP
Chatham County
Dear Mr. Green
In accordance with the application for a discharge permit received on October 19, 1995, -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.
In response to your March 29,1996 letter concerning the NPDES draft permit no. NCO026411 for the Town
of Siler City, the Division has addressed your specific concerns as follows:
1. The testing frequency and limits for mercury were both incorrect in the draft permit. Mercury should have a "
daily limit of 0.012 µg/1(as in the previous permit). The testing frequency should be weekly, not monthly. The
frequency change is due to a change in Division policy since the last permit was issued.
2. The draft permit indicates an incorrect MBAS daily maximum limit of 0.5µg/1. The MBAS daily maximum
limit should be 0.5 mg/1(as in the previous permit).
3. Enclosed you will find instream monitoring data sheets. These may be used as a guide when developing the
facility's annual stream monitoring report. As previously discussed, submitting the monitoring data on a 3.5"
computer disk would save the Division time used for data entry.
4. Chronic Toxicity should be monitored during the months of March, June, September and December (as in the
previous permit). The draft permit you received contained an incorrect monitoring schedule.
5. Daily monitoring for the parameters in this permit means monitoring Monday through Friday, excluding
holidays.
6. Although not mentioned in your March 29, 1996 letter, further review of the draft permit yielded other
incorrect monitoring frequencies. The incorrect and correct monitoring frequencies are listed below:

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

binding.
Please take note that this permit is not transferable. Part II, EA. 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 Environmental Management or permits required by the Division of Land Resources or any other
Federal or Local governmental permit that may be required.

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 Ceriod 13hnia 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 pormh Wild► :Hl! n,-rfr,-m
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 lnumha uj iMarch, Juuu,
September, and December. Effluent sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally,
DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests Performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this pornm nia) tic rL•-uln•ncd J110
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.

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment facilities?
Yes " No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No v
If yes, please provide a schedule (and basis for that schedule) with the regional office
recommendations:
If no, why not?
Wasteload sent to EPA? (Major) _ (Y or N)
(If yes, then attach updated evaluation of facility, including toxics spreadsheet, modeling analysisif modeled at
renewal, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.

Facility Name Siler City - Larkins Water Pollution Control Facility Permit # NCO026441
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chrome 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 %v (defined as treatment two in the North Carolina procedure document). The permit
holder shall perform r r monitoring using this procedure to establish compliance with the permit
condition. The first test will be performed after thirty days from the effective date of this permit during
the months of March, June, September, and December. Effluent sampling for this testing shall
be performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Fluent
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 environmentalcontrols, 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.

1981: modeled with limits of 17 mgA BODS, 6 mg/l NH3-N, 30 mgA TSS,1,000 / 100 mL fecal coliform, 6 - 9 SU pH, and 5 mg/l
dissolved oxygen for a 1.8 mgd discharge. 97010 estimated at 0.03 de. 1976 notes used for model
1985: SOC for flow, BODS, pH, and additional domestic flow allowed.
1986: remodeled with updated flows, (0010 estimated to be 0.2 ds 02.1017.6150'86). Limits of 15 mg/l BODS, 10 mg/l NH3-N,
30 mg/l TSS, 1,060 / 100 mL fecal coliform, 6 - 9 SU pH, and 5 mg/l dissolved oxygen for a 1.8 mgd discharge were
determined. An error in the BOD„ was made, and the limits were changed to 16 mg/I BODS and 5 mg/l NH3-N, or any other
equivalent.
1987: Speculative for increase to 3.0 mgd and possible relocation to from Loves Creek to Rocky River. Limits were more stringent
for GODS than Advanced Secondary, (refer letter dated 10 February,1987).
1988: JOC for additional winter flow due to I & I.
1989: re -modeled with updated flows, (0010 estimated to be 0.25 ds 02.1017.5150 '89) for an expansion to 4.0 mgd. Limits of
12 (24) mgA BOD5, 2 (4) mgA NH3-N, 30 mg/1 TSS,1,000 / 100 mL fecal coliform, 6 - 9 SU pH, and 6 mg/l dissolved oxygen
were determined. Also, nickel, cyanide, and chromium were limited and a Toxicity Test was added. Monitoring for other
metals and nutrient series was recommended. Instream monitoring locations, frequencies, and parameters were changed
and/or added to... A memo form David Vogt acknowledging possible future nutrient limits is included in this package.
Paul Wilms wrote a letter to the facility, (after the Permit review process) acknowledging the need for an EIS for this proposed
expansion due to "new rules" and public concern.
1990: An Environmental Group, (Friends of Rocky River) sent a review letter on the APAM for Slier City. Of the four parameters
which had'hits', (copper, zinc, beryllium, and lead) only lead had a standard - beryllium was said to not be bio-accumulative. A
lead limit was Included in the permit per Administrative letter. Letter form Town, (dated 19 March,1990) indicated change in
instream monitoring inaccurate and/or not possible. Memorandum from Trevor Clements, (dated 1 June,1990) covered a
meeting on a proposed SOC for flow exceedences and additional flow requested by various SIU's. These issues cannot be
resolved until EIS is completed.
1991: The 1988 permit was never issued due to public opposition and EIS/201 Facilities Plan requirements. A Level-C modeling
analysis was perfermed on this proposed expansion and Advanced Tertiary limits were recommended, as well as metals limits,
(and monitoring requirements), a Toxicity Test, and a summer Total Phosphorus limit Of 0.5 mg/l, (winter had a monitoring
requirement). Extensive notes on the modeling analysis were included with the Fact Sheet. A modeling report, (dated May,
1991) is also In the file. Also Included In this WLA file are back -and -fourth letters between EPA and George Everett, Director
about this permit. A note from Mike Scoville indicated a meeting was being set up to deal with this.
1993: A report from Water Planning, (dated 2 August 1993) now referred to as Water Resources covered a requested increase of
ten feet to the Rocky River reservoir. The report covers extensive monitoring and modeling of both flows and various fish and
benthos. The bottom line from a modeling perspective was the requirement of an interim minimum flow of 2.4 ds.
1994: The final minimum flow, (based on s7010) was 0.3 cfe, and the Town of Slier City was required to Install a flow meter.
1995: Letter, (dated 8 March, 1995) to facility indicated that 1.0 mgA NH3-N limit was based on modeling analysis and would remain
in permit.
DMR's
facility is discharging above 1.8 mgd and is therefore limited by the 4.0 mgd permit
NH3-N violation of the 1.0 !mgA limit in June, 1995
Chlorine is being measured to amazing levels I This facility has a device which continuously measures the milli -volts of the effluent and
through some type of conservative function, (which must subtract out the influence of conductivity, etc) it doses with the appropriate
level of chlorine. This is why this facility does not have a de -chlorination device. It is somewhat suspect as to whether these levels of
measurement are accurate, and it may also set this facility up for permit violations which may not be accurate. For example, on May
30, 1995, the reported level of residual chlorine was 17.0 µgA and it would be difficult to substantiate that this was an accurate measure
of a violation, (especially when most facilities are reporting < 100 µg/l and titration techniques can only get down to approximately 50
µ9n)•

Instream Data
Percent saturation data does not indicate any instream problems or general differences between up and downstream
Both total phosphorus and orthophosphate have higher than expected upstream levels, although the instream data near the discharge
point and below Indicate that the Input from the facility is not dramatically Increasing these concentrations. It also looks evident that the
summer total phosphorus limit has brought this waterbody into a phosphorus limited system, (this does mean that upstream levels of
total phosphorus can become more important
Nitrate / nitrite levels are very high both 200' below the discharge and at SR 2170. As phosphorus is the limiting nutrient, this shouldn't
cause algal blooms, unless the upstream Inputs increase....

1975: limits of 15 mg/l GODS, 3 mg/I TKN, 30 mg/l TSS, 200 / 100 mL fecal coliform, 6 - 9 SU pH, 900 / A 50 F, and 5 mg/l dissolved
oxygen for a 1.8 mgd discharge. s7010 : 0.25 cfs
1976: modeled with limits of 18 mg/l BODS, 6 mg/I NH3-N, 30 mg/l TSS, 200 / 100 mL fecal coliform, 6 - 9 SU pH, and 5 mg/l
dissolved oxygen for a 1.8 mgd discharge. s7Q10 looked to estimated at 0.03 cfs.
1981: modeled with limits of 17 mg/l BOD5, 6 mg/l NH3-N, 30 mg/l TSS,1,000 / 100 mL fecal coliform, 6 - 9 SU pH, and 5 mg/I
dissolved oxygen for a 1.8 mgd discharge. s7010 estimated at 0.03 cis. 1976 notes used for model
1985: SOC for flow, BODS, pH, and additional domestic flow allowed.
1986: remodeled with updated flows, (s7Q10 estimated to be 0.2 cfs 02.1017.5150 ,86). Limits of 15 mg/l BODS, 10 mg/I NH3-N,
30 mg/l TSS,1,000 / 100 mL fecal coliform, 6 - 9 SU pH, and 5 mg/l dissolved oxygen for a 1.8 mgd discharge were
determined. An error in the BODE was made, and the limits were changed to 16 mg/l BOD5 and 5 mg/l NH3-N, or any other
equivalent.
1987: Speculative for increase to 3.0 mgd and possible relocation to from Loves Creek to Rocky River. Limits were more stringent
for BOD5 than Advanced Secondary, (refer letter dated 10 February, 1987).
1988: JOC for additional winter flow due to I & I.
1989: re -modeled with updated flows, (s7010 estimated to be 0.25 cfs 02.1017.5150 189) for an expansion to 4.0 mgd. Limits of
12 (24) mg/l GODS, 2 (4) mg/l NH3-N, 30 mg/l TSS, 1,000 / 100 mL fecal coliform, 6 - 9 SU pH, and 6 mg/l dissolved oxygen
were determined. Also, nickel, cyanide, and chromium were limited and a Toxicity Test was added. Monitoring for other
metals and nutrient series was recommended. Instream monitoring locations, frequencies, and parameters were changed
and/or added to... A memo form David Vogt acknowledging possible future nutrient limits is included in this package.
Paul Wilms wrote a letter to the facility, (after the Permit review process) acknowledging the need for an EIS for this proposed
expansion due to 'new rules" and public concern.
1990: An Environmental Group, (Friends of Rocky River) sent a review letter on the APAM for Slier City. Of the four parameters
which had 'hits', (copper, zinc, beryllium, and lead) only lead had a standard - beryllium was said to not be blo-aocumulative. A
lead limit was included in the permit per Administrative letter. Letter form Town, (dated 19 March, 1900) indicated change in
instream monitoring inaccurate and/or not possible. Memorandum from Trevor Clements, (dated 1 June,1990) covered a
meeting on a proposed SOC for flow exceedences and additional flow requested by various SIU's. These issues cannot be
resolved until EIS is completed.
1991: The 1988 permit was never issued due to public opposition and EIS/201 Facilities Plan requirements. A Level-C modeling
analysis was performed on this proposed expansion and Advanced Tertiary limits were recommended, as well as metals limits,
(and monitoring requirements), a Toxicity Test, and a summer Total Phosphorus limit 0f 0.5 mg/l, (winter had a monitoring
requirement). Extensive notes on the modeling analysis were included with the Fact Sheet. A modeling report, (dated May,
1991) is also in the file. Also included in this WLA file are back -and -fourth letters between EPA and George Everett, Director
about this permit. A note from Mike Scoville indicated a meeting was being set up to deal with this.
1993: A report from Water Planning, (dated 2 August, 1993) now referred to as Water Resources covered a requested increase of
ten feet to the Rocky River reservoir. The report covers extensive monitoring and modeling of both flows and various fish and
benthos. The bottom line from a modeling perspective was the requirement of an interim minimum flow of 2.4 cfs.
1994: The final minimum flow, (based on s7010) was 0.3 cfs, and the Town of Slier City was required to install a flow meter.
1995: Letter, (dated 8 March, 1995) to facility indicated that 1.0 mg/l NH3-N limit was based on modeling analysis and would remain
in permit.
DMR's
facility is discharging above 1.8 mgd and is therefore limited by the 4.0 mgd permit
NH3-N violation of the 1.0 mg/I limit in June, 1995
Chlorine is being measured to amazing levels I This facility has a device which continuously measures the milli -volts of the effluent and
through some type of conservative function, (which must subtract out the influence of conductivity, etc) it doses with the appropriate
level of chlorine. This is why this facility does not have a de -chlorination device. It is somewhat suspect as to whether these levels of
measurement are accurate, and it may also set this facility up for permit violations which may not be accurate. For example, on May
30, 1995, the reported level of residual chlorine was 17.0 µg/l and it would be difficult to substantiate that this was an accurate measure
of a violation, (especially when most facilities are reporting < 100 µg/l and titration techniques can only get down to approximately 50
µg/1).

Instream Data
Percent saturation data does not indicate any Instream problems or general differences between up and downstream
Both total phosphorus and orthophosphate have higher than expected upstream levels, although the instream data near the discharge
point and below indicate that the input from the facility is not dramatically increasing these concentrations. It also looks evident that the
summer total phosphorus limit has brought this waterbody into a phosphorus limited system, (this does mean that upstream levels of
total phosphorus can become more important)
Nitrate / nitrite levels are very high both 200' below the discharge and at SR 2170. As phosphorus is the limiting nutrient, this shouldn't
cause algal blooms, unless the upstream inputs increase....
