1. The chlorine residual monitoring frequency has been changed from daily to 2/week. The 02B .0500
regulations only require that Class I and II facilities monitor for total residual chlorine 2/week
(although many facilities report daily or 5/week). Thus, the monitoring frequency has been changed to
correctly reflect the 02B .0500 regulation.
2. Special Condition G should have been met with the expansion to 0.50 MGD.
3. The treatment system originally consisted of influent pumps, screening, and two facultative lagoons
followed by chlorination. The treatment system has been modified to a wetland treatment system and
began operating on May 21, 1996. The treatment system modification has changed the treatment class
from I to II. For detail on modified treatment system, please refer to permit summary.
4. Compliance data was evaluated for the period July 1994 - August 1996. Since May 21, 1996, the
facility has even been complying with pre-SOC effluent limits. On site visit conducted September 17,
1996, Denise Shelton (ORC) stated that BOD values average 5-6 mg/1 and TSS average 3-4 mg/1. The
SOC requires final limits to be met by September 15,1996 and expires December 15,1996. li (( �'�rvi

NC0025526 Summary
September 20, 1996
Town of Walnut Cove has applied to renew their permit to discharge 0.50 MGD treated
wastewater.
The treatment system originally consisted of influent pumps, screening, and two facultative
lagoons followed by chlorination. The treatment system has been modified to a wetland
treatment system and began operating on May 21, 1996. The treatment modification has
changed the treatment class from I to II. It consists of a baffled lagoon (immediately
following the two facultative lagoons) with two types of duckweed and two lined vegetated
wetland basins.
The wastewater flows from the two facultative lagoons to the baffled duckweed lagoon
where baffles prevent the duckweed from collecting in one area of the lagoon. One section
of the duckweed pond supports water hyacinths which aids the treatment process. After
duckweed treatment, the flow is divided and proceeds to one of two lined wetland basins
vegetated primarily with cattails, although duckweed, Scirpus sp., and Polygonum sp. are
also growing in the vegetated lagoons. Finally, wastewater receives chlorination,
dechlorination, and flow measurement after leaving the vegetated areas, but before
discharge to the stream.
The treatment system discharges to Town Fork Creek (WS-IV) which flows into the Dan
River in the Roanoke River Basin.
Compliance Summary
Compliance data was evaluated for the period July 1994 - August 1996 and the violations
are compiled on the following table. Since May 21, 1996, the facility has even been
complying with pre-SOC effluent limits. On site visit conducted September 17,1996,
Denise Shelton (ORC) stated that BOD values average 5-6 mg/land TSS average 3-4 mg/1.
The SOC requires final limits to be met by September 15, 1996 and expires December 15,
1996.

Instream Monitoring
The permit requires instream monitoring for Fecal Coliform, Temperature, Conductivity,
and Dissolved Oxygen. However, there is no record of any instream monitoring in the
DMR files.
WLA Summary
The majority of the parameters monitored in this permit are effluent limited and will remain
unchanged in the forthcoming permit period.
The ammonia toxicity mass balance calculation using S7Q10 and permitted flows indicated
that the ammonia limits will also remain unchanged from the previous permit period: 10.0
mg/1(sumrrier) and no limit in the winter.
The chlorine toxicity mass balance calculation using S7Q10 and permitted flows indicated a
very high chlorine limit and thus the cap of 28.0 ug/1 will remain unchanged in the permit.
Total nitrogen and total phosphorus effluent concentrations were high, but treatment
system does not discharge into a nutrient limited stream. Monitoring for total nitrogen and
total phosphorus will continue especially because of the recent treatment system
modifications.

Note for Paul Clark
From: Farrell Keough
Date: Thu, Oct 3, 1996 5:25 PM
Subject: RE: Instream monitoring questions
To: Paul Clark
the modeling for both of these facilities indicated a sag at these distances from the effluent pipe(s).
if it would be easier for the facilites, they could monitor at these downstream locations:
CR Industries SR 1108
(should remain where I recommended in permit as this is first and closest downstream bridge
crossing)
Walnut Cove 300' downstream
(the model sag is still above 6.0 mg/1 and the small amount of discharge from this facility shouldn't
have more than a localized effect)

CR Industries - why is downstream monitoring station 2.5 miles downstream??
Town of Walnut Cove - similarly, why is downstream monitoring station 2 miles downstream (at
confluence of Lick Creek and Town Fork Creek)??
I let Dave know that you are working on developing a coordinated instream monitoring effort that
will probably include Town of Madison.
