INSTREAM MONITORING REQUIREMENTS

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
For the expanded flow, more advanced treatment will be required.
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
See wasteload allocation summary.
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) _N_ (Y or N)
(If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old
assumptions that were made, and description of how it fits into basinwide plan)
Additional Information attached? _N (Y or N) If yes, explain with attachments.

The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassa Procedure - Revised *September 1989) or subsequent versions. y
The effluent concentration al which their may be no observable inhibition of reproduction or significant mortality is .�96 (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
orm
Q�=monitoring using this procedure to establish compliance with the permit condition. The first test will be
p after thirty days from the effective date of this permit during the months of
-�14 011-Zr`'" _re' ) . Effluent sampling for this testing shall be performed at the NPDES
permitted effluent discharge below all treatment processes.
All toxicity testing results required as pars of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all chemical/physical
association with the toxicity tests, as wellas all dose/%spon�ta. Total r,esidal hl�e of the a performed it
sample must be measured and reported if chlorine is employed for disinfection of the waste stream. went toxicity
Should any single quarterly monitoring indicate a failure to meet wed limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in ilhe months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits,
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

2/1/93
Carolina Water Service, Inc. - Kings Grant Subdivision
NC0062219
- Kings Grant has applied for a permit renewal for its 0.21 MGD facility. Over the past
three years, the facility has been in compliance. No DO problems have been reported at
the upstream or downstream sampling sites over the past three years.
- Kings grant began whole effluent toxicity testing in 1991. Since then they have passed 7
of 9 reported tests. Toxicity may be due to residual chlorine, which has been as high as
1.0 mg/l.
- The facility discharges to a UT of Poplar Creek, C-NSW. The UT joins Poplar Creek
0.89 miles above the Neuse River. The UT has a zero 7Q10 and a 30Q2 of 0.08 cfs.
- A Level-b model developed for Poplar Creek predicts that Kings Grant, at its present
permit limits, results in BOD and NH3 concentrations at the bottom of Poplar Creek of
8.2 mg/l BOD5 and 3.8 mg/1 NH3 (See model results). These concentrations are above
the concentrations recommended in the Neuse Basinwide Plan and the NH3 concentration
is above the instream target. To meet the instream targets Kings Grant at 0.21 MGD
would have to meet summer limits of 5.4 mg/1 BOD5 and 3.1 mg/1 NH3.
- The existing facility is at 0.07 MGD. It is recommended that the permit be renewed with
two sets of limits, at 0.07 and 0.21 MGD. Existing permit limits are recommended for he
0.07 MGD flow. These limits are predicted to result in BOD5 and NH3 concentrations at
the mouth of Poplar Creek of 5.8 and 1.8 mg/1 respectively. These predicted loadings to
the Neuse River are lower than under the existing permit limits. The 0.21 MGD flow will
be treated as new and so will receive limits consistent with the zero flow policy and the
Neuse River Basinwide Plan. The expanded facility is predicted to result in BOD5 and
NH3 concentrations at the mouth of Poplar Creek of 4.5 and 0.8 mg/l respectively. These
concentrations are consistent with the Neuse River Basinwide Plan.
