and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007, or as subsequently amended.
We have made the following updates to the draft permit:
4 The instream monitoring special condition is removed from the permit.
We have made the following updates to your previous permit:
Y Included new monitoring for the upgraded 0.6 MGD wastewater treatment system in accord with the
Authorization to Construct(A to C) No. 020443A01. The engineering certification has not been
received.
• Added updates to facility map and parameter codes.
• Quarterly Mercury monitoring is included to provide a database for future mercury management.
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must submit
DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these
regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES

For Renewal —This permit reflects discharge at Oulfall 001. DWR updated the facility description and
Map; added parameter codes to Section A. (1); added Electronic Reporting- Discharge Monitoring
Reports page; added new limits and monitoring for expansion to 0.6 MGD; removed special instream
monitoring; and added Quarterly Mercury for TMDL.
Stream—Discharge from WWTP for out fall 001 is into the Scuppernong River [Stream Segment 30-14-4-
9]. The segment is not listed as impaired in the 2012 North Carolina 303(d) report and there is no usage
listing in the 2012 North Carolina Integrated report. Fecal coliform and conductivity monitoring were
removed per a April 22, 2002 memorandum since the water body is not impair for coliform and the
facility is not industrial for conductivity.
In-stream Monitoring— Special Instream monitoring was removed from the previous permit. The regional
office and Modeling and Assessment Branch concur with removing the special instream monitoring.
RPA--A Reasonable Potential Analysis(RPA) was not applicable for any parameters for this permit
renewal.
Implementation of 2012 Statewide Mercury TMDL—Columbia W WTP was not required to sample for
mercury in the previous permit. Quarterly Monitoring for Mercury is added to the permit.

Subject: FW: Final for NC0020443 Town of Columbia Removal of Condition A.(3.) Instream Monitoring Requirements
Kathy,
We have a permit that is up for renewal that has special instream monitoring in the Scuppernong River(Pasquotank
River Basin). it is for the Town of Columbia WWTP permit NC0020443. We considering the removal of the special
instream monitoring for the permit renewal. . Do you know if anyone in your unit is using this data for modeling? We
don't really have any solid reason for why this requirement was added to the permit or why it has remained in the
permit for a number of years.
The special condition is required from June 1 to September 30 each year. Sampling required for DO,Temp, Salinity,
Conductivity and pH is grab sampling at one-meter intervals. Nutrients and Chlorophyll-a are required as composite
sampling throughout the photic zone at twice the secchi depth.
I have found a few notes in the permit files from around 1995 in reference to DO and Chlorophyll being an issue in the
Scuppernong, The 1995 notes also mention comparison to a nearby ambient monitoring station. One other possibility
for the special instream monitoring would be because of the diffusers at the outfall. Also they were under an SOC in
1984 in order to add 6000 gpd to their 170,000 gpd flow at the time. It was noted in a 1984 memorandum, that DO
would not drop in the river for this additional flow. One last note, if I am not mistaken,this segment of the Scuppernong
is not currently listed as being impaired for anything.
For your reference, I have attached both versions of the draft permit (with and without the special instream monitoring
condition) and a current permit map.
. 1

We don't want to remove the special instream monitoring unless we know for sure the data is not being used for
anything. If you or your staff know anything about this or have any input please let me know.
Thanks,
Derek

Subject: Final for NCO020443 Town of Columbia Removal of Condition A.(3.) Instream Monitoring Requirements
Everyone,
A question has come up for the final of the Town of Columbia WWTP along with the ATC for the upgrades. (The WWTP
was upgraded from 0.3 to 0.6 MGD, which is now Grade Ill.) The question is why are we requiring the Town of Columbia
to do the special sampling in Condition A.(3.) (see original draft permit). The special condition is required from June 1
to September 30 each year. Sampling required for DO,Temp, Salinity, Conductivity and pH is grab sampling at one-
meter intervals. Nutrients and Chlorophyll-a are required as composite sampling throughout the photic zone at twice
the secchi depth.
Considering that they will be required with great difficulty to report this on eDMR, was there any reason that you can
recall in the past for why this special condition was included in the permit? We have instream data to give an answer,
but we have forgotten the question.
I have included attachments for two versions of the permit(with and without the special condition for instream
monitoring). The new version excludes the Instream Monitoring Condition and leaves all instream samples as grab. The
frequency will be 3 times a week for DO,Temp, Salinity, Conductivity(according to 15A NCAC 02B .0508 for a Grade III
plant). The remaining parameters pH, NH3 as N,TKN, NO3-NO2-N,TN and Chlorophyll-a will be Quarterly instead of
2/Month. I open to ideas for these frequencies if we go without the special condition.
I have found a few notes in the permit files from around 1995 in reference to DO and Chlorophyll being an issue in the
Scuppernong. Also they were under an SOC in 1984 in order to add 6000 gpd to their 170,000 gpd flow at the time. If
was noted in a 1984 memorandum,that DO would not drop in the river for this additional flow. The 1995 notes also
mentions comparison to a nearby ambient monitoring station. One other possibility for the special instream monitoring
i

would be because of the diffusers. One last note, if am not mistaken,this segment of the Scuppernong is not listed as
being impaired for anything.
Please let me know if you have any thoughts, agree or disagree with removing this condition or have an suggestions for
instream monitoring frequencies if we go without the special instream condition.
Thanks,
Derek

Regarding item 2, I'll add the diffuser sampling location. The other sampling locations (Influent, Effluent, Upstream &
Downstream) are all captured with the existing outfall 001. Before I do that, we're going to determine if the
requirement to sample instream at multiple depths can be deleted. It's been in the permit for 20 years and the file
doesn't say why. We're not using that data, so that's a cost we should lift from the permittee.
Regarding item 3, both Effluent and Instream samples are required for TKN and NO2+NO3. I've corrected BIM5.
Regarding item 4,the missing "I" location was added.

NC0023965
Charles,
asked John if I needed QA/QC the recent ATC activation for Columbia and Wilmington, he said go ahead and do it.
Here's the results for Columbia:
1) All listed activations dates,expiration dates, monitoring frequencies were correct.
2) There is an issue with the instream monitoring as there are three sample locations required. Per Bob last email (I
think what I recall) to make this work in BIMS will require setting up another outfall. FYI - A.(4) list the three
locations.
3) The quarterly effluent sampling locations for TKN and Nitrite/Nitrate Nitrogen are listed as "U,D" should be "E".
4) The sampling location for TSS at 0.3 MGD only list "E"and omits "I". This is a moot point I assume since 0.6 MGD
will be effective in 2 weeks. The TSS sample points for 0.6 MGD are correct.
Hope this is helpful.

Robbie,
Do we have an engineer's certification yet? I called the operator and spoke with him today. Sounds like his plant is too
big for a flow less than 0.3 and that may create'problems for monitoring and their budget. I will have to write the permit
renewal for the 0.6 MGD upgrade, but they will have to do a permit modification application to have any of monitoring
frequency reduced. I will send you a draft for your review before I send this one to public notice, but I will need the
engineer's certification first.
Hope you are having a good one.
