Subject: Chlorine Toxicity
NPDES Permit No. NC0067288
Henderson County
Dear Mr. Barr:
Director
Chlorine, a widely used wastewater disinfectant for the treatment of coliform
organisms, often remains instream in residual amounts that may prove to be toxic under
critical low stream flow conditions. In the last decade, EPA assessed the potential adverse
effects of chlorine to the aquatic environment and has taken steps to reduce the impacts
through the development of federal criteria. In 1986, EPA recommended that all states
have a chlorine standard by their next triennial review of water quality standards.
In revising its water quality standards in 1989, North Carolina developed an action
level for chlorine of 17 ug/I (freshwater classes only). In addition, the fecal coliform limit
was reduced from 1000 colonies/100 nil to 200 colonies/ 100 ml. Under a new DEM
procedure, dechlorination and chlorine limits are now recommended for all new or
expanding dischargers proposing the use of chlorine for effluent disinfection. The
Division is reviewing chlorine levels from all existing dischargers as part of their NPDES
permit renewal process.
Our records indicate that chlorine from your facility's effluent discharge is
considered toxic to the receiving stream under low flow conditions, i.e., the amount of
chlorine discharged causes a violation of the instream action level for chlorine (17 ug/1 for
chronic effects and 28 ug/1 for acute effects) under 7Q10 conditions. An acceptable level
of chlorine in your effluent is 28 ug/1 or 0.028 mg/l. Action should be taken to reduce the
effluent concentration of chlorine to an acceptable level. If this level is not feasible, you
should consider dechlorination or alternate methods of disinfection for your facility to
ensure that both chlorine and bacterial limits are met. In addition, if your facility plans to
undertake any phase of construction, dechlorination or alternate disinfection should be
included. However, please note that an authorization to construct must be obtained from
this Division prior to any alteration to your treatment plant.

The Division is currently reviewing its water quality regulations pertaining to
chlorine. In the future, effluent limits and/or dechlorination may be required of existing
facility's with chlorine problems. If the chlorine levels in your facility's effluent remain
unchanged, a chlorine limit or a whole effluent toxicity testing requirement may be added
to your permit limitations.
Please feel free to call Forrest Westall of the Division's Regional Office at (704)
251-6208 if you have any questions or comments regarding this issue.
Sincerely,

PART IV - EVALUATION AND RECOMMENI)AT I ONS
HydroLogic, Inc. has requested renewal of NPDES Permit No.
NC0067288 for the continued operation of wastewater treatment
facility serving the Hunters Glenn Subdivision. The existing
facility is a 0.035 MGD system. The NPDES Permit was issued for
a 0.070 MGD system. Construction was done in phases with the
first phase at 0.035 MGD. The permit should have two effluent
pages for both the 0.035 MGD system and the future expansion to
0.070 MGD.
HydroLogic obtained this sewer utility franchise as result
of a bankruptcy filled by the original utility developer. The
sewer system in this development is a pressure sewer system with
individual home pump tanks. These pump tank systems have proven
to be very maintenance intensive and there have been numerous
outages. HydroLogic does feel that they are responsible for the
maintenance of the sewer system. A public hearing was held by the
State Utilities Commission in efforts to resolve this issue among
others. It is our opinion that when HydroLogic assume this
franchise they also became responsible for the entire system
including the sewer system. The renewed permit should require
HydroLogic to file(within 180 days following issuance of the
permit) an executed agreement with the Hunters Glenn Subdivision
on how maintenance is to be provided for the sewer system
including individual home pump tanks.
It is recommended that the above condition be including
standard condition on abandonment of the system upon available
public sewer.
