PERMIT FOR THE DISTRIBUTION OF RESIDUALS OF EXCEPTIONAL QUALITY
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended, and
other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO THE
County of Harnett
Harnett County
FOR THE
operation of a facility for the distribution and marketing of residuals which meet exceptional quality standards
throughout the State of North Carolina, consisting of the distribution of 917 dry tons per year of residuals from the
sources listed in Condition 112, with no discharge of wastes to the surface waters, pursuant to the application
received on January 16, 1998, and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural Resources and considered a part of
this permit.
This permit shall be effective from the date of issuance until March 31, 2003, and shall be subject to the
following specified conditions and limitations:
I. PERFORMANCE STANDARDS
The distribution residuals program shall be effectively maintained and operated as a non -discharge
system to prevent the discharge of any wastes resulting from the operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to adequately protect
the assigned water quality standards of the surface waters and groundwaters.
The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or groundwaters resulting from the operation of this program.
4. In the event that the residuals program is not operated satisfactorily, including the creation of nuisance
conditions, the Permittee shall take any immediate corrective actions as may be required by the
Division of Water Quality (Division).
S. Diversion or bypassing of the untreated residuals or leachate from the residual treatment facilities is
prohibited.
6. All dewatering supernate from the subject water treatment plant shall be properly. treated and disposed
in accordance with the permit issued to the Town of Lillington. The County of Harnett should ensure
that the collection system can handle the additional wastewater volume. The Fayetteville Regional
Office has indicated that several sewer overflows were a result of the dewatering process. The County
of Harnett should ensure that no additional overflows occur due to their operations.

7. If the water treatment residuals are to be sold or provide a guaranteed nutrient analysis then the North
Carolina Department of Agriculture, Fertilizer Section, telephone number [phone], should be

may be placed on a concrete pad, placed under shelter or covered until such time as it is distributed to
the buyer. If an alternate storage site is to be used, approval must be obtained from the Division.
4. No other residuals other than those specified under Condition II 2 above may be distributed. The

PART III --OTHER PERTINENT INFORMATION (continued)
Description of proposed Systern: '
The Harnett County Water Treatment Plant produces drinking water for the surrounding
area residents. The Water Treatment plant is currently expanding to produce speak flow
Of 12 MGD. The : facility utilizes upflow • solids contact technology using alum for
coagulation. It is estimated that the new treatment will generate 917 dry tons of (alum)
residuals per year. Design plans call for two (2) existing settling basins to be converted
to liquid residuals holding tanks. These tanks have a total combined, useable volume of
575,000. gallons (287,500 gallons each). The residuals produced by the upflow solids
contact process will have a concentration of 0.1 to 0.5 percent solids. ,he holding tanks
referenced above, will be designed to concentrate the dilute iresiduals,Tto 2 to 3 .percent
solids. Two horizonial'mixers-have been installed in each tank to {assure thorough mixing;
when the residuals are spiked' with a 30% o Nitrogen Solution enhancing the nutrient value.
It should be understood that design and construction of these basins was permitted
through the State's Dept. Of Environmental Health - Public JWater Supply Branch.. It is
estimated at full capacity the`new plant will produce betweeri 7 ,and 11 M' G per year of 2
to 3 percent solids.
.AMSCO Incorporated has developed the concept . of making the ' alum residuals a
desirable product/program to be permitted for -Distribution and Marketing. The proposed -
program will have four distinct benefits to program participants: Those benefits are: 1)
nutrient value, 2) organics added to soil to enhance soil quality, 3) pH adjustment, and
4) irrigation water.
The proposed program design is as follows:
It is proposed that AMSCO will blend commercially available 30% Nitrogen. Solution
with Alum Residuals (2 -to 3 % solids) ' in the holding tank(287,500 gallons). The
blending ratio is based on an application rate of 19,500 gallons'iper acre for a maximum
equivalency of 113.29 lbs,' of (Total -PAN) Plant Available Nitrogen Per Acre' The
blended -residuals will be thoroughly mixed with the two honzonal mixers in,the holding
tanks. The homogenous blend willthen be pumped to transportation tankers via the truck
loading station for distribution/land application on agricultural crops (hay; pasture,row
crops).. In additiori to the nutrient value, the crop will realize an irrigation benefit with the
appliance of 19,500 gal/ac(water). AMSCO has included in the program a soil pH
adjustment bonus, which will provide for (up to) one ton periacre of dolomitic limestone.
Soil=pH adjustment will be calculated upon soil test results for all receiver sites and crop
type.

PART III OTHER PERTINENT INFORMATION (continued) ;
Special Conditions to be addressed: 4;
1) 'The Harnett County Water treatment Plant .currently under construction was
approved by the Water . Supply Branch. This office has concerns with the
dewatering process. Concerned citizens' complaints have revealed . sewer
overflows as the result of sup emate dewatering. Is the supernate dewatering part
of this alum proposal? Supemate dewatering could have a detrimental effect on
the City of Lillington's Collection System. We need a.condition addressing, the
City of Lillington's sanitary sewer system's ability to handle the supernate
wastewater, without causing wastewater plant upset or! spill.
,,
2) We have: discussed this proposal to blend the alum sludge with commercial liquid
Nitrogen (30% solution) with many different .individuals. Even though the final
permit will be a Distribution and Marketing permit, it is strongly encouraged by
all parties contacted . that the permit for distribution of alum sludge with the
inclusion of commercial fertilizer be . approved by the NC Department of
Agriculture. Ms. Susan Baker, Fertilizer Administration; Plant Industry Division,
216 W. Jones Street, P.O. Box 27647, Raleigh, N.C. Zip,' 27611, concurs with this
recommendation.- The FRO feels that if this alum sludge proposal is approved by
the N.C. Department of Agriculture as a fertilizer, then !DWQ would.not receive
all the blame if an incident on a private farm causes a crop failure. Thus, we
recommend that a . condition be included to ' require NCDA approval prior to
applying of this product.
• it
PART IV - EVALUATION AND RECOMMENDATIONS
PI �
it is the recommendation of this office that the subject application address the Special
Conditions in Part III of this staff report and after a favorable review by the non -
discharge staff, along with receiving approval from the North Carolina Department of
Agriculture, the appropriate. Distribution and Marketing Permit be issued .to Harnett
County. If additional information is needed, please advise. i;'
