fractions that apply to your industry and for ALL toxic metals,cyanides,and total phenols. If you are not required to mark column 2-a(secondary industries,nonprocess wastewater outfalls, and nonrequired GC/MS
fractions),mark"X"in column 2-b for each pollutant you know or have reason to believe is present.Mark"X"in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant,you must
provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater.If you mark column 2b for acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part;please review each carefully. Complete one table(all 7 pages)for each outfall. See instructions for

N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc.by a factor of 4 or more or%RPD not applicable.
A The Relative Percent Difference(RPD)obtained from the sample duplicate (DUP)is evaluated against the acceptance criteria when the sample is greater than
five times(5X)the contract required detection limit(RL).In cases where either the sample or duplicate value is less than 5X the RL,a control limit of+/_the
RL is used to evaluate the DUP result.

For PS,PSD,and SDILT results,the values listed are the measured amounts,not final concentrations.
Where the analytical method has been performed under NELAP certification,the analysis has met all of the

Sludge Management Plan
Wastewater Treatment System Improvements
Huffman Finishing Company
Granite Falls, North Carolina
NPDES Permit No. NC0025135
The Huffman Finishing Company operates the 0.25 mgd extended aeration (Oxidation
Ditch) type activated sludge plant which discharges its effluent into Catawba River(Lake
Hickory) in accordance with the requirements set forth in the NPDES Permit
NC0025135. The plant includes screening, flow equalization, extended aeration type
activated sludge system, chlorine disinfection, pre and post dechlorination, post aeration,
influent and effluent flow metering and sampling facilities, aerobic sludge
stabilization/storage facilities, and disposal of stabilized sludge by land application in
accordance with the requirements set forth in the land application of residuals (Non-503)
Permit No. WQ002431. The settled sludge from the clarifier is periodically wasted to two
(2) aerobic stabilization/storage basins for stabilization, settling and supernatant
withdrawal operations. The supernatant withdrawn is recycled back at the headwork for
reprocessing. The process of sludge wasting, stabilization, settling, and supernatant
withdrawal is repeated and the stabilized sludge is disposed of once a year by land
application at agronomic rates.
The estimated waste activated sludge quantity of 325 lbs/day (4,775 gallons/day at
specific gravity of 1.02 and 0.8 percent solids), at design conditions, will be aerobically
stabilized to comply with the Class B pathogen reduction requirement, included in item
no I.7 of the land application of residual solids Permit No. WQ002431. The Permit does
not require Vector Attraction Reduction requirements. However, the existing aerobic
sludge stabilization/storage facilities are adequately designed to comply with the Vector
Attraction Reduction requirements. The 227 lbs/day (890 gallons/day at specific gravity
of 1.02 and 3.0 percent solids) aerobically stabilized sludge will be disposed of by land
application at agronomic rates on the permitted sites, using a private contractor engaged
in sludge or residual disposal service. For disposal of the stabilized sludge by land
application, the Huffman Finishing Company will comply with the pathogen reduction
requirement and vector attraction reduction requirement as follows:
Class B Pathogen Reduction: Compliance with the Class B pathogen reduction will be
• achieved by using one of the following alternatives:
Alternative 1: Monitoring of Fecal Coliform(EPA 503.32 (b) (2)).
Alternative 2: Use of PSRP Aerobic Digestion and Lime Stabilization (EPA
503.32 (b) (3))
Vector Attraction Reduction: Compliance with the vector attraction reduction will be
achieved by using one of the following options:
Option 1: Reduction of volatile solids content(EPA 503.33 (b) (1))

Option 4: Specific Oxygen Uptake Rate for aerobically digested sludge (EPA
503.33 (b) (4))
Option 6: Addition of alkali (EPA 503.33 (b) (6))
Option 9: Injection below ground (EPA 503.33 (b) (9))
Option 10: Incorporation of sludge into the soil (EPA 503.33 (b) (10))
