City of Mount Holly Residuals
Land Application Program
Land Application of Residual Solids (503)
Gaston County
Dear Mr. Price:
In accordance with a written request made by the City of Mount Holly that was received by the
Division of Water Quality (Division) on July 18, 2002, we are forwarding herewith a corrected Permit
No. WQ0001863, issued on December 28, 1999, for the subject residuals land application program.
The following corrections have been made to the permit:
1. The Permittee's request stated that the equalization basin at the wastewater treatment plant is
only cleaned once every five to seven years. It was explained that the 56-dry ton per year
residuals generation rate that was allowed by the permit is really an annualized average of
that which would be expected to be generated during the cleaning event. A normal cleaning
event would put the Permittee in violation of this generation rate/land application limit.
Therefore, the permit has been corrected to reflect the fact that the Permittee may now land
apply up to 280 dry tons of residuals from the equalization basin in a single year. Note that
language has been added to the permit to reinforce the fact that all sampling and analysis
performed on the residuals accumulated in the equalization basin should be done
representatively as well as separately from those performed on the residuals generated by the
activated sludge process.
2. The Division has taken this opportunity to reissue this permit in the format currently being
used for all residuals land application programs. This format was developed to facilitate new
application review procedures that have been put into place by the Division. Although no
substantive changes have been made to the conditions contained within this permit, the
Permittee should take the time to review this document to ensure complete familiarity and
understanding of the format and the condition language.
Please replace the entire permit with this corrected permit into Permit No. WQ0001863,
issued on December 28,1999.

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.
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.

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 II. 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 listed in Condition H. 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.
5

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 Iand 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 land
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.
No

III. 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.
2. Residuals generated by each residuals source -generating facility listed in the mast -recently -

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

After the residuals have
been monitored as specified above 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 request a reduction of this
monitoring requirement.
In no case, however, shall the frequency of monitoring be less than
once per permit cycle.

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 Iess 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 and vector attraction 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 A pathogen reduction requirements in 40
CFR Part 503.32(a) or the Class B pathogen reduction requirements and site restrictions in 40
CFR Part 503.32(b) as well as one of vector attraction reduction requirements in 40 CFR Part
503.33. In addition, the Environmental Protection Agency (EPA) certification statements
concerning compliance with pathogen reduction requirements, vector attraction reduction
requirements, and management practices shall be completed quarterly 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 I. 7. in the most recently -certified Attachment A of this permit shall
not be required to comply with this monitoring requirement.
S. Laboratory analyses as required by Condition III. 2., Condition M. 3., and Condition 111. 4.
shall be performed/gathered on the residuals as they are to be land applied. Furthermore,
analytical determinations made pursuant to the monitoring and reporting requirements of this

9. Noncompliance Notification:
The Permittee shall report by telephone to the Water Quality Section of the Division's
Mooresville 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
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 Compliance Boundary for each land application site is established at either 250 feet
from the residuals land application area or 50 feet within the property boundary,
whichever is closest to the residuals land application area. An exceedance of
Groundwater Quality Standards at or beyond the Compliance Boundary is subject to
immediate remediation action according to ISA NCAC 2L .0106 (d)(2).
b. The REVIEW BOUNDARY shall be established around each land application site
midway between the Compliance Boundary --and the perimeter -of the residuals Iand
application area. Any exceedance of Groundwater Quality Standards at the Review
Boundary shall require action in accordance with 15A NCAC 2L .0106 (d)(2).
Additional Requirements:
a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
V. INSPECTIONS
1. Prior to each residuals land application event, the Permittee or his designee shall inspect the
residuals storage, transport, and application facilities to prevent malfunctions and
deterioration, operator errors, and discharges that may cause or lead to the release of wastes
to the environment, a threat to human health, or a nuisance. The Permittee shall maintain an
inspection log or summary including at least the date and time of inspection, observations
