Request For Time Extension
Total Residual Chlorine Limit
Jordan Lake Water Treatment Plant
NPDES Permit No. NC0084093
Chatham County, North Carolina
Chatham County is hereby requesting a minor modification to the Town's existing
NPDES Permit No. NC0084093 regarding the effective date for the total residual chlorine (TRC)
effluent limit at the above referenced facility. This permit includes a TRC effluent limit of 17
µg/1 that is scheduled to take effect on November 1, 2007.
The County is currently in the design phase of a project that will expand the capacity of
the plant from 3.0 to 6.0 million gallons per day (MGD). As a result, we have been considering
the possibility of including the construction of the new dechlorination facility as part of the plant
expansion project. Due to recent delays in the schedule for completing construction of the
expansion, the County has elected to proceed with the installation of the new dechlorination
facilities prior to constructing the plant expansion.
Plans have been completed for the new dechlorination system and a Fast Track
Application has been submitted to NCDWQ for review and approval. Once the Division issues
an Authorization To Construct, the County is planning to proceed with construction of the new
facilities. In order to provide adequate time to construct, test, and operate the new facilities, the
County hereby respectfully requests that the effective date for the TRC effluent limit be extended
by four (4) months to March 1, 2008.

We appreciate your consideration of this important matter. If you have any questions or
would like to discuss this request in greater detail, please do not hesitate to contact Mike Apke,
P.E. at McGill Associates at 910-295-3159, or contact me at 919-545-8530.

Michele, I am working on the modification request for Jordan Lake WTP, and I have
gone in & corrected the information in BIMS. The facility discharges into/ New Hope
River Arm of B. Everett Jordan Lake/. I have also updated the facility address info
to reflect /Apex/ as the City (fyi - the wrong zip code caused the incorrect city to
be reflected in BIMS). All should be correct now.

Hey Danny. We are ready to issue the ATC there are just a couple of problems we
need help with. Please see the email below, to Gil from Anita. Do you know the
answers to her questions?
Gil:
I have an ATC dechlorination fast track application for Jordan Lake WTP with the
above NPDES permit. According to BIMS the plant is at 290 Beaver Creek Road in
Pleasant Garden. The utility director indicated the address is actually in Apex.
Would you please let me know which is correct? Also, the name of the receiving
stream in BIMS is Camp New Hope Lake. Since the plant is on Jordan Lake wouldn't
the receiving stream be Jordan Lake? I appreciate your help in resolving this
matter.
Thanks,
Anita Reed

Danny,
I do not see a reason not to give them the extension especially since they are
only requesting a few additional months. I did an inspection in April and they
were compliant. I also looked at what they have been reporting for TRC and
they have reduced the amount in the past few months without de-chlor, therefore
they are aware of the situation.
Hope this helps,
