Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility proposing to increase flow from 0.48 MGD to 0.60 MGD and to increase
production from 600,000 #/day to 750,000 #/day. I updated flows (HA10 and MAR=1.3) due to
facility expanding flow and ran a Level B model. The guideline limits will protect D.O. instream.
The allowable NH3N = 20 mg/1 based on new flows. IWC changed to 3.9%. Faciliaty has failed
WET test 3 times at P/F 2.5% since 8/93. There are excessive levels of NH3N ( month max =
73.7 mg/1) and Chlorine (month max =1.4 mg/1) in the effluent. I recommend adding a chlorine
limit and giving facility a compliance schedule so they can install necessary facilities.

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 ;,` % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quarterly 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
3 14-02 Tut- 1 ocr . 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 ipdicate 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.

PART IV - EVALUATION AND RECOMMENDATIONS
Wayne Farms wants a 25% increase in chicken production.
Their actual treatment capacity is unknown but Cabe Associates,
Inc. has stated that their treatment system can handle the
increase from 0.48 MPD to 0.60 MGD.
This office has no objections to the production increase or
subsequent increase in wastewater discharge as long as permit
limits are met.

.0004 DEFINITIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physkaVc hemkal method for reducing soluble 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 either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin in which ail solids are maintained in suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through bask;
(3) Mratbn. A process of bringing about intimate contact between aft or Ngh purity oxygen in a liquid by spraying. agttatbn or di fusion.(3a) Extended
Aeration. An activated sludge process utilizing a mdnlmum hydraulic detention time of 10 hours.
(4) Agriculturally managed site. Any she on which a crop is produced. managed. and harvested (Crop includes grasses. grains. trees, eta);
(5) Air Stripping. A process by which the ammonium ion is first cornerted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene. toluene. and xylem,;
(t3�nReRege ratlon. The regeneration d exhausted carbon by the use of a firma to provide extremey Ngh temperatures which volatilize and oxidize the
abs(7) Carbonaceous Stage. A stage of wastewater treatment designed to'actievs affluent limits;
(a) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of different denstt1es
(a) Chemical Addition Systems- The addition of chemical(s) to wastewater at an application point for purposes d improving solids removal. pH adjustment.
alkalinity control. eta; the capability to experiment with different chemicals and different application points to achieve a spectnc result win be considered one
system; the capability to add chemical(s) to dual units win be rated as one system; capability to add a chemical at a different application points for different
purposes will result in the systems being rated as separate systems;
(10) Chemical Sludge Condtibning. The addition of a chemical compound such as lime. Ionic chbtide. or a polymer to wet sludge to coalesce the mass prior to
is application to a dewaterff g device;
(11) Closed Cyds Systems. Use of holding ponds or holding tanks for containment of wastewater contalntng Inorganic, non -toxic matertak from sand. gravel,
crushed stone or other similar operations. Such systems shag carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nttrtfkatbn. A single stage system required to achieve permit effluent limits on BOD
and ammonia narogsn within the same biological reactor.
(13) Dechbrtnatbn. The partial or complete reduction of residual ctiortne in a liquid by arty chemical or physkai process;
(14) Denitr[fkatbn Process. The conversion of nitrate -nitrogen b nitrogen gas;
