Land Application of Residual Solids (Non -503)
Caldwell County
Dear Mr. Huffman:
In accordance with your application package for permit renewal and modification received on
January 24, 2004, we are forwarding herewith a modified and renewed Permit No. WQ0002431, dated
May 30, 2006, to the Huffman Finishing Company for the continued operation of the subject residuals
land application program.
This permit shall be effective from the date of issuance until April 30, 2011, shall void Permit No.
WQ0002431, issued on September 30, 1999, and shall be subject to the conditions and limitations as
specified therein. Please note that new conditions have been added which include pathogen requirements
(Condition 1.7); timely notification prior to initial residual land application on any site (Conditions 1.10 &
I.11); actions to be taken if the residuals have a high sodium concentration (Condition H.10); restrictions
on nitrogen loadings (Condition 11.11); monitoring pathogens (Condition 1I1.4); and the sampling of
residuals prior to their application (Condition III.5). Please also make note of this permit's expiration
date and the fact that a permit renewal application is due to the Division of Water Quality (Division) no
later than six months prior to that date (i.e., see Condition VI. 7.), as the Division does not send reminders
to apply for permit renewal.
This pen -nit approves the continued operation of the residuals land application program for
another five-year cycle. This permit is being issued to modify the program by decreasing the amount of
approved area on which residual application takes place. This is being performed as a result of revised
buffers on the existing sites and does not involve the addition or the removal of application sites. Please
note that this pen -nit is being issued only in a new format to facilitate new permit review procedures that
have been put into place by the Division. As always, remember to take the time to review this permit
thoroughly, as some of the conditions contained therein may have been added, changed, or deleted since
the last issuance. Pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and maintaining the required operational information will
result in future compliance problems.

on all land application sites onto which residuals are land applied to ensure optimum yield for
the crops specified in Condition U. 13. The agronomist shall provide information on the pH
best suited for the specified crop and the soil type. a
10. Should any of the residuals generated by the residuals source -generating facilities listed in the
most recently -certified Attachment A of this permit contain a high salt content (i.e., high
sodium adsorption ratio (SAR) of five or higher), the exchangeable sodium percentage (ESP)
or other method as approved by the Division, using the results from the annual soils analysis
as required by this permit, shall be monitored on all of the land application sites. The local
Cooperative Extension Office, the Department of Agriculture and Consumer Services, the
Natural Resource Conservation Service, a North Carolina -licensed Soil Scientist, or other
agronomist shall review the results and make recommendations regarding soil amendments
(e.g., gypsum, etc.) or other ameliorative mechanism for maintaining the integrity of the site in
terms of suitability for land application of residuals and maintaining conditions conducive to
crop growth. The Permittee shall implement such recommendations accordingly and shall
maintain written records of each monitoring event that includes details of the sites covered
and rate of soil amendment application.
4

11. Prior to land applying residuals to any land application site that has previously received or is
intended to receive animal waste (e.g., poultry litter, etc.) or other source of nutrients (e.g.,
fertilizer, etc.) in the future, the Permittee shall obtain information pertaining to the volume
and analysis of the applied waste/nutrients from the landowner and/or lessee/operator of the
site. The Permittee shall be responsible for verifying the volume of residuals that may be land
applied to the site such that the plant available nitrogen (PAN) loading rate for the specified
crop (i.e., see Condition 11. 13.) shall not be exceeded by all of the sources of PAN applied.
Should the maximum PAN loading rate be met or exceeded, then no additional residuals shall
be land applied to the site.
12. A suitable vegetative cover, as Iisted in Condition II. 13., shall be maintained on land
application sites onto which residuals are land applied in accordance with the crop
management plan outlined by the local Cooperative Extension Office, the Department of
Agriculture and Consumer Services, the Natural Resource Conservation Service, or other
agronomist and as approved by the Division.
13. Residuals and other sources of PAN shall be land applied to all land application sites at
agronomic rates in accordance with the crop management plan outlined by the local
Cooperative Extension Office, the North Carolina Department of Agriculture and Consumer
Services, the Natural Resource Conservation Service, or other agronomist. Under no
circumstances shall the following PAN loading rates land applied to any site exceed the
following for the specified crops:
The Permittee shall apply for and receive a modification of this permit before land applying
residuals on any land application site that is to be established in a crop other than those listed
above. A maximum PAN loading rate for the desired crop shall be approved with the permit
modification.
If the land application sites are to be overseeded (e.g., bermuda grass in the summer and rye
grass in the winter with BOTH crops to receive residuals), then the second crop shall receive
an application of PAN at a rate of no greater than 50 pounds per acre per year. This practice
shall be allowed as long as the second crop is to be harvested. If the second crop is to be
planted for erosion control only and is to be tilled into the soil, then no residuals shall be land
applied to these sites because the PAN will essentially be returned to the soil.

above. A maximum PAN loading rate for the desired crop shall be approved with the permit
modification.
If the land application sites are to be overseeded (e.g., bermuda grass in the summer and rye
grass in the winter with BOTH crops to receive residuals), then the second crop shall receive
an application of PAN at a rate of no greater than 50 pounds per acre per year. This practice
shall be allowed as long as the second crop is to be harvested. If the second crop is to be
planted for erosion control only and is to be tilled into the soil, then no residuals shall be land
applied to these sites because the PAN will essentially be returned to the soil.

Residuals shall not be land applied at rates greater than agronomic rates, unless authorized by
the Division.
14_ Animals shall not be grazed on any land application site for 30 days after any residuals land
application event. Sites that are to be used for grazing shall have fencing that will be used to
prevent access after each event.
15. Food crops, feed crops, and fiber crops that do not come in contact with the residuals shall not
be harvested for 30 days after any residuals land application event.
16. Food crops with harvested parts that touch the residual/soil mixture and are totally above the
land surface (e.g., tobacco, melons, cucumbers, squash, etc.) shall not be harvested for 14
months after any residuals land application event.
17. Food crops with harvested parts below the surface of the land (i.e., root crops such as potatoes,
carrots, radishes, etc.) shall not be harvested for 20 months after any residuals land application
event when the residuals remain on the land surface for four months or longer prior to
incorporation into the soil.
18. Food crops with harvested parts below the surface of the land shall not be harvested for 38
months after any residuals land application event when the residuals remain on the Iand
surface for less than four months prior to incorporation into the soil.
19. Turf shall not be harvested for one year after any residuals land application event.
20. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying
residuals from the land application sites onto adjacent properties or into any surface waters.
21. Adequate procedures shall be provided to prevent surface runoff from carrying any land
applied or stored residuals into any surface waters.
22. Surface -applied residuals shall be plowed or disced within 24 hours after land application on
land application sites with no cover crop established.
23. For land application sites that are prone to flooding or within the 100 -year flood elevation,
residuals shall be land applied only during periods of dry weather. The residuals shall be
incorporated into the soil within 24 hours after land application.
24. Residuals shall not be land applied during inclement weather or until 24 hours following a
rainfall event of 0.5 -inch or greater in 24 hours. Any emergency residuals land application
measures shall first be approved in writing by the Division.
25. Residuals shall not be land applied to any land application site that is flooded, frozen, or
snow-covered.
26. Appropriate measures shall be taken to control public access to the land application sites
during active site use and for the 12 month period following the last residuals land application
event. Such controls may include the posting of signs indicating the activities being
conducted at each site.

M. MONITORING AND REPORTING REQUIREMENTS
Any monitoring (i.e., including groundwater, surface water, residuals, soil, or plant tissue
analyses) deemed necessary by the Division to ensure protection of the environment shall be
established, and an acceptable sampling and reporting schedule shall be followed.
Residuals generated by each residuals source -generating facility listed in the most -recently -
certified Attachment A of this permit shall be analyzed to demonstrate that they are non-
hazardous under the Resource Conservation and Recovery Act (RCRA). A corrosivity,
ignitability, and reactivity analysis as well as a Toxicity Characteristics Leaching Procedure
(TCLP) analysis shall be conducted on residuals generated by each residuals source -
generating facility listed in the most recently -certified Attachment A of this permit. The
analyses shall be performed at the frequency specified in the most recently -certified
Attachment A of this permit, and the results shall be maintained on file by the Permittee for a
minimum of five years. If residuals generated by a particular residuals source -generating
facility are land applied at a frequency less than that which is specified in the most recently -
certified Attachment A of this permit, the analyses shall be required for each residuals land
application event. Only residuals that are generated by the residuals source -generating
facilities that are identified as being exempt from this condition in the most recently -certified
Attachment A of this permit shall not be required to comply with this monitoring requirement.

3. An analysis shall be conducted on residuals generated by each residuals source -generating
facility listed in the most recently -certified Attachment A of this permit. The analysis shall be
performed at the frequency specified in the most recently -certified Attachment A of this
permit, and the results shall be maintained on file by the Permittee for a minimum of five
years. If residuals generated by a particular residuals source -generating facility are land
applied at a frequency less than that which is specified in the most recently -certified

After the residuals generated by a particular residuals source -generating facility have been
monitored for two years at the frequency specified in the most recently -certified Attachment A
of this permit, the Permittee may submit a request to the Division for a permit modification to
reduce the frequency of this monitoring requirement. In no case, however, shall the frequency
of this monitoring be less than once per year when a residuals land application event of
residuals generated by the residuals source -generating facility occurs during that year.
4. Residuals generated by each residuals source -generating facility listed in the most recently -
certified Attachment A of this permit shall be monitored for compliance with Condition I. 7.
The monitoring shall be performed at the frequency specified in the most recently -certified
Attachment A of this permit, and data to verify pathogen reduction of the residuals shall be
maintained on file by the Permittee for a minimum of five years. The required data shall be
specific to the stabilization process utilized, but also shall be sufficient to demonstrate clear
compliance with the Class B pathogen reduction requirements and site restrictions in 40 CFR
Part 503.32(b). In addition, the Environmental Protection Agency (EPA) certification
statements concerning compliance with pathogen reduction requirements and management
practices shall be completed at the frequency specified in the most recently -certified
Attachment A of this permit by the proper authority or authorities, if more than one is
involved (i.e., either the person who prepares the residuals, the person who derives the
material, or the person who applies the residuals). Only residuals that are generated by the
residuals source -generating facilities that are identified as being exempt from Condition 1. 7.
in the most recently -certified Attachment A of this permit shall not be required to comply with
this monitoring requirement.
5. Laboratory analyses as required by Condition III. 2., Condition III. 3., and Condition III. 4.
shall be performed/gathered on the residuals as they are to be land applied. Furthennore,
analytical determinations made pursuant to the monitoring and reporting requirements of this

acre, or kilograms per hectare (if applicable);
j. Volume of soil amendments (i.e., lime, gypsum, etc.) applied in gallons per acre, dry ton
per acre, or kilograms per hectare (if applicable); and
k. Annual and cumulative totals of dry tons per acre of residuals as well as animal waste and
other sources of nutrients (i.e., if applicable), annual and cumulative pounds per acre of
each heavy metal (i.e., shall include, but shall not be limited to, arsenic, cadmium, copper,
lead, mercury, molybdenum, nickel, selenium, and zinc), annual pounds per acre of PAN,
and annual pounds per acre of phosphorus applied to each field.
A representative annual soils analysis (i.e., Standard Soil Fertility Analysis) shall be
conducted on each land application site on which a residuals land application event in the
respective calendar year has occurred or is to occur, and the results shall be maintained on file
by the Permittee for a minimum of five years. The Standard Soil Fertility Analysis shall
include, but is not necessarily limited to, the following parameters:
Acidity Exchangeable Sodium Percentage (by calculation)
Calcium Magnesium Phosphorus
Cation Exchange Capacity Manganese Potassium
Copper Percent Humic Matter Sodium

and Condition III. 7. shall be submitted annually on or before March 1st of the year following
the residuals land application event to the following address:
NCDENR DWQ
Information Processing Unit
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

Noncompliance Notification:
The Permittee shall report by telephone to the Aquifer Protection Section of the Division's
Asheville Regional Office at telephone number [phone], as soon as possible, but in no
case more than 24 hours or on the next working day following the occurrence or first
knowledge of the occurrence of any of the following:
a. Any occurrence with the residuals land application program that results in the land
application of significant amounts of residuals that are abnormal in quantity or
characteristic.
b. Any failure of the residuals land application program resulting in a release of material to
receiving waters.
c. Any time that self-monitoring information indicates that the residuals land application
program has gone out of compliance with the conditions and limitations of this permit or
the parameters on which the program system was designed.
d. Any process unit failure, due to known or unknown reasons, that render the residuals land
application program incapable of adequate residuals treatment.
e. Any spillage or discharge from a vehicle or piping system transporting residuals to the
application site.
Persons reporting such occurrences by telephone shall also file a written report in letter form
within five days following first knowledge of the occurrence. This report shall outline the
actions taken or proposed to be taken to ensure that the problem, does not recur.
IV. GROUNDWATER REQUIREMENTS
1, Land Application Site Requirements:
a. Each land application site identified with a GW -A in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
greater than three feet below the land surface. Residuals land application events may
occur on these sites throughout the year.
b. Each land application site identified with a GW -B in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
between one and three feet below the land surface. Residual land application events on
these sites shall be prohibited from December through March, inclusive. No residuals
shall be land applied to these sites when the vertical separation between the depth of
residuals land application and the water table is less than three feet. The actual water
table depth for seasonally -restricted soils shall be verified by soil borings within 24 hours
prior to any residuals land application event that occurs from April through November,
inclusive. The number of borings advanced shall be sufficient to characterize water table
conditions across the land application site adequately. Any open borings shall be properly
filled with native soil, prior to the residuals land application event, to decrease the chance
of any residuals contaminating the groundwater.
10

2. Applicable Boundary Requirements:
a. The COMPLIANCE BOUNDARY for residuals land application programs is specified by
regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The
