Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
This facility discharges into a swamp. Both upstream and downstream dissolved oxygen values
often reach 1.0 and 2.0 mg/1 dissolved oxygen. Dismantling of beaver dams in the area should
help with flushing and increase dissolved oxygen levels. Continued instream monitoring should
verify this; request Region input as to locations and frequency's of instream monitoring
recommendations.
Also, request Region input as to toxics requirements with regards to facilities proposed to tie into
this plant. Should any of the parameters not recommended in this Fact Sheet receive either limits
or monitoring due to possible additional constituents from these connections? wc.,5t- ((o/ID),

Stream samples shall be collected three times per week during June, July, August, and September and once
per week during the remaining months of the year.
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?
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:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
(If yes, then attach updated evaluation of facility, including toxics spreadsheet, modeling
analysisif modeled at renewal, and description of how it fits into basinwide plan)
Additional Information attached? (Y or N) If yes, explain with attachments.

Facility Name Whiteville - White Marsh WWTP Permit # NC0021920 Pipe # 001
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
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
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant
mortality is 45 % (defined as treatment two in the North Carolina procedure document). The permit
holder shall perform quartery monitoring using this procedure to establish compliance with the permit
condition. The first test will be performed after thirty days from the effective date of this permit during the
months of Jan., Apr., Jul., and Oct. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part 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 supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of
the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should any single quarterly monitoring indicate a failure to meet specified 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 the 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.

Subject: Speculative Limits
Town of Whiteville Waste Water Treatment Plant
NPDES Permit #: NC0021920
Columbus County
Thank you for the opportunity to provide comments on the upgrade and possible expansion of your
Town's Waste Water Treatment Plant. As you are probably aware, the Division of Environmental
Management is currently implementing the Lumber River Basin Management Plan; therefore, review of
your permit and this request for expansion will incorporate any applicable stratagies outlined in this
management plan.
The stream segment where your discharge is located is classified C - Swamp waters. Self -monitoring
data required by the current permit show many instances of substandard dissolved oxygen levels above
and below the discharge location. This situation is exacerbated under critical low flow conditions, (Le.
summer 7010; minimum average flow for a period of seven consecutive days that has an average
recurrence of once in ten years) since the discharge from the Whiteville wastewater treatment plant
constitutes approximately fifty percent of the stream flow to White Marsh. The Division of Environmental
Management's Wilmington Regional Office has indicated that beaver dams exist on White Marsh and may
be the cause of the low dissolved oxygen levels in White Marsh. Future efforts will be put forth between
the Federal Dept. of Agriculture and Columbus County to remedy this situation.
It is not clear at this time what effects the discharge from the Whiteville wastewater treatment plant is
having on White Marsh. The Town of Whiteville, along with other facilities in this subbasin have been
given limits less stringent than 15 mg/I BON and 4 mg/l NH3-N based on previous analyses and recorded
instream substandard dissolved oxygen values. New discharges in this subbasin will receive limits of 5
mg/I BOD5 and 2 mg/I NH3N. Since the Town of Whiteville is already permitted at these levels, the
expanded discharge will be required to continue to meet advanced tertiary treatment limits. The following
table outlines the proposed speculative limits for the Whiteville expansion; specific limits for various toxics
and metals will be determined upon completion of the wasteload allocation and information on toxics of
concern.

Under current DEM procedure, dechlorination as well as chlorine limits are now required for all new or
expanding dischargers proposing the use of chlorine for disinfection. The level of residual chlorine in
your effluent, necessary to ensure against acute toxicity in White Marsh would be 28.0 µg/I (daily maximum
limit). The process of chlorination / dechlorination or an alternative form of disinfection, such as ultraviolet
radiation, should allow the facility to comply with the total residual chlorine limit.
We would also like to take this opportunity to note that Inflow and Infiltration (I/1) has been an ongoing
situation for this facility. As stated in the Environmental Assessment, flows "are over three times higher in
wet weather than in dry weather." Our Wilmington Regional Office estimates that I/1 can contribute as
much as 2 to 3 million gallons per day during large storm events. The Town should address I/1 before it
expands.
We would request that you re-evaluate your options of upgrade. If problems of Inflow and Infiltration
are substantially remedied, no expansion request may be necessary. If you find that an expansion
request is still the most viable option for your Town's future growth plans, an Environmental Assessment
of your proposed expansion would be required due to the stream dominating nature of your discharge,
per North Carolina's Environmental Policy Act T15A: 01 C .0504 (3) (a).
Finally, the above advanced tertiary limits are speculative and are for use in an engineering review of
your discharge alternatives. Final limits will be provided upon issuance of the Town of Whiteville's
modified NPDES Permit If you have any questions concerning the above issues, please call Farrell
Keough at [phone].

Re: Request for Increase in Flow Capacity
City of Whiteville, NPDES Permit #: NC0021920
Dear Mr. Safrit:
In reference to your letter dated August 22, 1994 concerning
the City of Whiteville's request for increasing its wastewater
treatment plant's permitted flow from 2.5 mgd to 3.0 mgd, please
consider the following:
1. The City of Whiteville is not proposing a project to
upgrade or expand the treatment facility. Our request is
for an increase in permitted flow capacity based on the
capacity of the existing facility to treat higher flows.
We acknowledge that some modifications such as
dechlorination may be necessary as a part of the
requested increase.
2. The increased wastewater flows expected during the next
five years would be strictly domestic in nature from the
Town of Brunswick and Georgia-Pacific Corporation. The
characteristics of flows from the proposed landfill and
industrial park are not known at present but all flows
accepted by the City would be in compliance with the
pretreatment program and the sewer use ordinance.
3. As indicated in our report, peak flows during wet weather
have been recorded as high as three times the normal
expected dry weather flow. These high flows, however,
have not affected the capability of the treatment system
in meeting effluent limits. Please note also that
inflow/infiltration (I/I) in the system is not considered
excessive when evaluated by the criteria established by
DEM for preliminary I/I analyses (evaluation attached).

Mr. Donald Safrit, P.E.
September 21, 1994
Page Two
The City plans, however, to continue ongoing efforts to
reduce I/I and to seek State Revolving Loan funding
through DEM to assist in completion of these efforts.
The City is currently in the process of completing an
evaluation of the entire collection system, and
developing a plan for addressing and correcting problem
areas on a scheduled basis.
Please note that a major portion of the WWTP
modifications completed in 1991 was conversion of one of
the two existing aeration basins to function as a flow
equalization basin. This modification has reduced peak
flows during wet weather and helped to stabilize the
treatment process during these high flow periods. Since
this conversion, no monthly effluent violations have
occurred other than monthly average flows that exceeded
2.5 mgd in January and April, 1993.
4. The treatment system analysis performed by Black & Veatch
indicates that the effluent limits would continue to be It
� 1 wad
met at 3.0 mgd under peak daily organic loading wy
conditions. Obviously, the organic loading at the WWTI,'6hek
would be significantly less during peak I/I conditions 1*e
and leaves no doubt regarding our ability to continue to p.:,
meet advanced limits at 3.0 mgd. azas 0.41-
-Namr.egr
5. We understand DEM's comments concerning the capability of
White Marsh Swamp to assimilate additional treated
wastewater even at advanced limits. As indicated,
however, by our sampling data, the stream conditions have
not changed and stream dissolved oxygen levels are not
being depressed by Whiteville's WWTP effluent.
If the conditions in White Marsh Swamp are considered to
reflect water quality problems (other than normal swamp
water conditions), it does not appear that such problems
are resulting from Whiteville's WWTP effluent.
We ask for your consideration of the above matters in the
continued consideration of our request. Please contact City
Manager Jeff Emory, or City Engineer Kip McClary, [phone],
if you have any questions or additional information is needed.

INFILTRATION/INFLOW ANALYSIS
Criteria used by NC-DEM for preliminary evaluations:
Infiltration: Excessive if average flow for a 3-5 inch
rainfall storm period minus expected flow divided by the

mile
From WWTP flow data: Avg. of three separate storm flows

Inflow: Excessive if non -industrial peak flow from a 1-inch 6:7

Peak April 17 flow = 1.9 mgd w/rainfall of 1.7 inches
Population served = 6312
Industrial flow = approx. 100,000 gpd
Inflow = (1.9-.1) x 106/6312 = 285
This exceeds 275, but is probably not excessive since the
rainfall was 1.7 inches.
