Wasteload Allocation Summary:
The facility is requesting a renewal of its existing permit. Limits on conventional
parameters will not be changed with the exception of the ammonia tox limit, which was recently
dropped from the permit. The facility will face new limits when it expands due to its location
upstream from ORW. The plant failed 3 tox tests in a row in 93-94, apparently because of a
problem with leachate it accepts from the county landfill.

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 1 / % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
guarterjy monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed cater thirty days from the effective date of this permit during the months of
fe tA4v A v3r Nov . Effluent sampling for this testing shall be performed at the NPDES
permitted filial effltnt discharge below all treatment processes.
g
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.

MEMO
To: WLA File
From: Jim Blose
Subject: Summary of issues for Jefferson WWTP renewal
Date: July 11,1995
Jefferson is currently applying for a renewal at .300 MGD. In 1993 the plant applied for
an expansion to .375 MGD but withdrew its request once it realized what the new limits would be.
Throughout this process the listed design capacity was .385 MGD. The reason for this is obscure.
Jefferson has an ATC for only .300. When the facility does expand it will have to meet the limits
specified in the 0200 regs for the South Fork New River ORW Area (BOD=5, NH3=2, TSS=20).
The draft of the New River basin plan notes that Naked Creek is rated as partially supporting
below the plant. 1993 biomonitoring rating was fair (the rating was poor in 1986).
The plant consistently violates ammonia tox limits in the summer. There is some
discussion regarding this limit in our files --in particular whether the facility should have been given
an ammonia tox limit in the first place. While the permit files give no indication that the limit has
been removed, the WSRO has provided a copy of a permit modification issued in April to remove
the NH3 limit. Cl and CN limits have each been violated once in the past year. The Cl limit was
put in the permit in 1992 when the plant switched from UV to a contact chlorine chamber. The
plant has passed its only WET test this year, but failed 3 times in a row in 93-94.
Current limits were set in a 1992 WLA, using a 7Q10=2.8. The WLA for the withdrawn
1993 expansion request used a new USGS 7Q10 estimate of 2.2 cfs. A new Level B model was
developed at this time. A 7Q10 of 2.8 was used for the toxics analysis conducted for the present
WLA since no expansion is involved (toxics data: used: May 94 to April 95). Based on a review
of the most recent data, a mercury limit has been recommended.
Analysis of LTBOD data indicates a CBOD/BODS ratio of 6.68, probably due to
refractory carbon.
Pretreatment report (from Bo McMinn, 7-5-95):
The town is currently monitoring effluent quarterly but qualifies for the modified program and
could thus cut back. Major dischargers are a rubber company and a hospital. Hospital has had
past problems with Ag and Hg, but should have improved Hg recently (note: there have been 2 Hg
detects this year). There may not be much the town can do about Hg now that the hospital is in
compliance. Main source of metals is leachate from the County landfill. The WWTP has a
running feud with the county about this. Pretreatment has no concerns about dropping the
monitoring requirements for several metals, as recommended in the WLA.
From the region (George Smith, WSRO, 7-11-95):
The ammonia tox limit has been removed. The plant is maintained fairly well, although it is a
difficult facility to operate. Jefferson is aware of the ORW issue and is looking into nondischarge
alternatives. The County opened a new landfill in 92 and the plant had tox problems as soon as it
began accepting leachate. This is the reason for the WET test failures several years ago. The
leachate is extremely high in Zn, NH3 and BOD (See note above on LTBOD).

The following definlbns shag apply throughout this Subchapter.
(1) Activated Carbon Beds. A physkatrchemlcat method for reducing sotubis organic material from wastewater effluent; The column -type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be shher upflow or downfbw carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(2) Aerated Lagoons. A basin In which all solids are maintained in suspension and by which blobgicaf oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intimate contact between air or high purtty oxygen in a liquid by spraying. aghatbn or dtffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agriculturally managed site. Any she on which a crop Is produced. managed. and harvested (Crop includes grasses. grains. trees, etc.);
(5) Air Stripping. A process by which the ammonium ion is first converted to dtssotved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remave petroleum products such as benzene. toluene. and xylem;
(8) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely Ngh temperatures which votstgtzs and oxidize the
absorbed impurities;
(7) Carbonaceous Stage. A singe of wastewater treatment designed to'acNeve 'secondary' effluent limits;
(8) Centrifuge. A mechanical device in which centrifugal force is used to separate solids from liquids or to separate liquids of different denials;
(9) Chemical Addition Systems- The addition of chemical(s) to wastewater at an application point for purposes of improving solids removal. pH adjustment.
alkalinity control. etc.; the capability to experiment with different chemicals and different application points to acNeve a specific result wgl be considered one
system; the capability to add chemical(s) to dual unlit will be rated as one system; capability to add a chemical at a different application points for different
purposes will resuh In the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as lime. tonic ddodde. or a polymer to wet sludge to coalesce the mass prior b
Ns application to a dewatertng device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing inorganic. nontoxic materials from sand. gravel.
crushed stone or other similar operations. Such systems shalt carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous SOD and Nitrogenous Removal by Nttriticatbn- A single stage system required to achieve permit effluent limits on SOD
and ammonia nbrogen within the same bioiogtcal reactor;
(13) DecNortnatlon. The partial or complete reduction of msidual cNottne in a liquid by any chemical or physical process;
014) Denitr9icatbn Process. The csnvorsbn of ntlrate-nitrogen to nitrogen gas;
