Permit NC002140r
A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 24%.
The permit holder shall perform at a minimum, auarterlq monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed 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.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed. If reporting pass/fail results using the
parameter code TGP3B, DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic Value
results using the parameter code THP3B, DWQ Form AT-3 (original) is to be sent to the following address:

Dear Ms. Fields:
FEB 2 1 ?,fin;
This letter is in response to the draft permit for the Town of Highlands WWTP permit
#NC0021407. In the draft permit, it presumed that we kept the capability to chlorinate.
We have removed the chlorine and dechlorination capabilities. Also, on the authorization
to use the following components list, we need to need to eliminate the Chlorine injection
tank, the Dechlorination tank, and the Dual 15,700-gallon chlorine contact basins. It
looks like the list used the components before the upgrade on the plant. The components
now being used are: - Influent screen
- Dual 0.75 MGD sequencing batch reactor tanks, each with 25 HP
floating mixers, gravity decanters, and 3 HP sludge wasting pumps
- 100 HP blowers with fine bubble diffusers and motorized inlet
valves
-Sludge digesting system
-331876 gallon post -equalization basin
-UV Disinfection
- Tertiary filtration
-Ultrasonic flow meter
- 355 GPM dual -pump lift station
If you have any questions or comments, please contact me at [phone].

Proposed Changes Incorporated into Permit Renewal
• Facility has expanded to 1.5 MGD. Description has changed to include tertiary filtration and
UV disinfection.
• Facility is now a "major". Draft permit will need to be sent to EPA for review.
• Add TRC footnote that limit and monitoring only apply if chlorine is used for disinfection.
• Remove silver monitoring based on zero detections during the review period.
• Reduce copper monitoring to twice per month to be consistent with requirements for other
major facilities.
• Remove toluene limit and reduce monitoring to twice monthly.
II. Summary
The Highlands WWTP was expanded to serve as a regional treatment facility. The facility treats
100% domestic wastewater and does not have a pretreatment program:
The draft 2008 303(d) list does note that the Cullasaja River is impaired (due to dams), but the
impairment is in two segments upstream of the discharger. This segment of the Cullasaja is not
impaired.
III. Compliance Summary
DMR Data Review
DMRs were reviewed for September 2005-September 2007. A summary of this data is provided
below in Table 1. Since the expansion, the facility has ceased chlorinating its effluent and begun
to use UV disinfection. The facility has not had any violations of its permit limits for
conventional parameters.

RPA Analysis
RPAs were performed for toluene, copper, and silver. The facility has had weekly monitoring
requirements for all three parameters. Out of 108 samples reported, there were no detections for
silver, therefore the monitoring requirements will be removed. Copper showed reasonable
potential to cause an exceedance of water quality standards, however this is an action level
parameter so a limit will not be added. Copper monitoring will be reduced from weekly to
2/month to be consistent with requirements for other major facilities.
There were no detections of toluene during a review of 24 months of data. The limit for this
parameter will be removed and monitoring will be reduced to twice monthly.
WET Test Results
The Highlands WWTP has only been required to perform WET monitoring since its expansion.
The facility currently has chronic limit at 24% effluent concentration. They have passed 7/7 tests
administered since June 2006.
Correspondence File Review/Compliance History
The facility experienced two weekly average violations of its toluene limit in January and
February 2005. These violations were just outside the two-year review period used for RPA
calculations.

this letter their request for renewal.
It should be noted that since the Town last renewed their NPDES permit, they modified it during an
expansion from 0.5 to 1.5 MGD. The expansion also included tertiary filtration and UV
disinfection.
Please note that the Town's application is incomplete however the Town is diligently working to
complete their application. WKD is working to complete the application on behalf of the Town
and currently is awaiting the following information from the Town:
1. One (1) expanded effluent testing data set (we currently have 2 sets of data — one from
11/11/05 and one from 10/25/06).
2. Four (4) sets of a minimum of quarterly toxicity testing data
3. three (3) sets of a minimum of monthly sludge sampling data
Please don't hesitate to contact me if you have any questions or concerns at [phone].

The purpose of this Residuals Management Plan is to provide general and technical
information in the Town of Highlands' effort to adequately address the residuals
generated by the Cullasaja River Wastewater Treatment Plant.
2. EXISTING & PROPOSED FACILITY & CURRENT CONDITIONS
Periodically, a portion of the sludge blanket at the Town of Highlands Cullasaja River
Wastewater Treatment Plant is wasted to reduce the volume of sludge in the SBR's and to
control the F/M ratio. This sludge requires conditioning in preparation for dewatering and
disposal. The first phase of conditioning is to create a low F/M ratio environment so that
the sludge is more completely degraded. This is accomplished by transferring the sludge
from the SBR to an aerobic digester. The aerobic digesters in the case of the proposed
expansion are the existing SBR's, with process modifications to function as digesters. New
SBR's are to be constructed as part of the proposed expansion from 0.5 MGD to 1.5 MGD.
In the proposed digesters, the microorganisms are not receiving a fresh supply of organic
waste, so they must more thoroughly consume the waste and other organisms present.
Mixing is provided to prevent the wastes from settling and to ensure that the
microorganisms stay in close contact with the wastes and the oxygen supplied by a diffused
air system.
Sludge is removed from the proposed aerobic digesters during a settling phase and pumped
to the sludge holding basin (Existing Aerobic Digester). Supernatant shall be decanted to
the existing on -site pump station and then pumped to the headworks for further treatment

due to the high organic concentration of the supernatant. The existing aerobic digester will
be used primarily as a sludge holding tank, prior to dewatering. The existing aerator will
be relocated to the proposed Post EQ Basin. An air system will be installed to allow the
waste degradation process to continue and to keep the sludge fresh.
Sludge will then be pumped to the existing belt press for dewatering in preparation for
landfill disposal. The dewatered sludge is stored on the existing sludge vacuum bed until it
is transferred to the landfill. Before dewatering, the sludge is conditioned with polymer to
aid the dewatering process. Water from the dewatering process is cycled to the on -site
pump station and sent back through the plant headworks. Summarized below are the key
features of the aerobic digesters and the sludge handling process.

Processes to Significantly Reduce Pathogens (PSRP) — Sewage sludge is agitated with air to
maintain aerobic conditions in the aerobic digesters for a minimum mean cell residence
time of 40 days at 20 °C (see the attached calculations).
Residuals are disposed of at the Macon County Landfill (Permit No. 5703-P01).

4. CONCLUSIONS
The purpose of this Residuals Management Plan is to provide general and technical
information in the Town of Highlands' effort to adequately address the residuals generated
by the Cullasaja River Wastewater Treatment Plant. The Town of Highland's existing
residuals management system is more than capable of handling the Town's residuals at 0.5
MG D and 1.5 MG D.

Bob,
Thanks for looking into this for us some more and calling me back today.
As for your questions, below is what I have been able to ascertain:
1. Toxicity Testing was previously conducted on 3/7/02, 4/4/02, & 4/4/02 as part of their revised permit
(when they expanded to 1.5 MGD) with ceriodaphnia.
2. Their new NPDES permit (good through October 31, 2007) requires them to annually do a PPA test
and test quarterly for chronic toxicity using ceriodaphnia dubia.
The NPDES renewal application requires Highlands to:
A. Conduct three PPA's in conjunction with the Town's currently quarterly toxicity testing
B. Conduct four toxicity tests for an organism other than Ceriodaphnia to be done quarterly in
conjunction with the Town's current toxicity test (which is done in March, June, September, &
December)
C. Send all info to the Department no later than May 4, 2007.
D. Data can't be over 4.5 years old
Tests conducted to date are as follows:
1. Two PPA's — one in 10/06 and one in 10/05
2. Quarterly testing with ceriodaphnia
3. 1 set of altemate species toxicity tests which we believe was done on or around 8/27/02
At this point, it would appear that they need to do the following:
i. Conduct one more PPA and do it in conjunction with alternate species toxicity testing in March of this
year
ii. Submit the results of all three PPA's and the one altemate species testing in March by May 4, 2007
Conduct the three remain alternate species tests in June, September & December of this year and
submit when complete (i.e. I am assuming the 1 set of alternate species toxicity won't qualify due to
the time when conducted — the Town and WKD are looking at their records for additional tests)
Please let me know if you concur. Thanks.
