because it is thought to more accurately reflect the beneficial characteristics inherent in sewage
sludge.
Part 503 is being developed in two phases. Phase I of the risk-based regulation, which this
document addresses, does not cover all types of sludge, but rather addresses the following:
• Scum or solids removed from primary, secondary, or advanced wastewater treatment
processes
• A material derived from sewage sludge
• Domestic septage.
The following types of sludge are not subject to Part 503 but are regulated under the designated
Federal rules when land applied:
• Sludge generated during treatment of industrial process wastewater at an industrial
facility (40 CFR Part 257, if nonhazardous)
• Sewage sludge generated at an industrial facility during the treatment of industrial
wastewater combined with domestic sewage (40 CFR Part 257)
• Hazardous sludge, including hazardous sewage sludge (40 CFR Parts 261, 264, 265,
266, 267, and 268)
• Sewage sludge with polychlorinated biphenyl concentrations of 50 ppm or greater
(40 CFR Part 761)
• Drinking water treatment sludge (40 CFR Part 257)
• Grit or screenings generated during the treatment of domestic sewage (40 CFR Part
257).
Part 503 imposes requirements on four groups of persons:
• Persons who prepare sewage sludge or a material derived from sewage sludge
• Land appliers of sewage sludge

• Owners/operators of sewage sludge surface disposal sites
• Owners/operators of sewage sludge incinerators.
In an effort to explain the many different aspects of Part 503 to the regulated community, EPA
has developed a series of guidance documents. A list of these documents is provided in the
reference section at the end of this document.

Section One Introduction
1. INTRODUCTION
The U.S. Environmental Protection Agency promulgated a regulation at 40 Code of Federal
Regulations (CFR) Part 503 to ensure that sewage sludge is used or disposed of in a way that
protects human health and the environment. Part 503 imposes requirements for the land
application, surface disposal, and incineration of sewage sludge. This manual focuses on land
application, providing guidance to land appliers of sewage sludge.
The purpose of this document is to provide the land applier with sufficient guidance to comply
fully with all applicable Part 503 requirements. The Part 503 regulation is largely self
implementing, which means that anyone engaged in activities covered by the regulation must
comply with the appropriate requirements on or before the compliance deadline (see Exhibit 1).

February 19, 1994*
*If compliance requires construction of new pollution control facilities, compliance is required as expeditiously as
possible but no later than February 19,1995. A new pollution facility is any building, structure, facility, or installation
from which there is or may be a discharge of pollutants, the construction of which began after the promulgation of Part
503, and includes any building, structure, facility, or installation that replaces or substantially upgrades the process or
production equipment necessary to meet a standard under Part 503. The definition of new pollution control facility does
not include replacement of any building, structure, facility, or installation due to normal operational wear and tear, or
installation of monitoring equipment or devices, including the purchase of computer hardware or software for monitoring
purposes.
This guidance is structured to first provide a general understanding of the Rule and its
underlying principles, including definitions of sewage sludge, land application, and an
explanation of who under the Rule is considered a land applier. Section 1 discusses the general
factors that are taken into account in determining the land applier's responsibilities under the
Rule. Section 2 summarizes the seven basic types of Part 503 requirements for land application.
-------
Introduction Section One
The number and stringency of requirements for land appliers discussed in Chapter 2 depends
upon the quality of the sewage sludge and the circumstances under which it is being applied.
Section 3 simplifies the process of determining which requirements apply in different situations
by presenting nine possible land application scenarios based on quality, and provides a
comprehensive list of requirements for each. All the land applier must do to know which
requirements apply in his or her situation is to locate the scenario that most resembles his (her)
particular circumstances. Section 4 contains additional information that may be needed to enable
the land applier to fully document compliance with the requirements listed in Section 3.
1.1 Definition of Land Application
Land application is defined as the spreading, spraying, injection, or incorporation of sewage
sludge, including a material derived from sewage sludge (e.g., compost and pelletized sewage
sludge), onto or below the surface of the land to take advantage of the soil enhancing qualities
of the sewage sludge. Sewage sludge is land applied to improve the structure of the soil. It is
also applied as a fertilizer to supply nutrients to crops and other vegetation grown in the soil.
Sewage sludge is commonly applied to agricultural land (including pasture and range land),
forests, reclamation sites, public contact sites (e.g., parks, turf farms, highway median strips,
golf courses), lawns, and home gardens.
Sewage sludge is land applied in bulk form or sold or given away in a bag or similar container
for application to the land. The term "bulk" implies sewage sludge that is applied generally in
large quantities to large parcels of land. Bulk sewage sludge is typically used by commercial
and municipal appliers for agriculture, tree and turf farms, golf courses, parks, and reclamation
of construction or surface mining sites. Sewage sludge sold or given away in a bag or other
container is generally used by the smaller scale user, such as a home gardener or landscaper.
In disturbed areas such as mining sites, where there is no soil substrate from which to sustain
vegetation, large amounts of nitrogen and organic material may be required to re-establish basic
plant cover. When sewage sludge is used in these areas to supply the adequate substrate, it is
often necessary to apply quantities that exceed the agronomic rate. In such cases, sewage sludge
-------
Section One Introduction
is generally applied once, and then the site is seeded. Because of the highly soluble nature of
nitrates, which are the main nutritive component of both sewage sludge and standard fertilizer
products, sewage sludge applied in this manner has the potential for nitrate contamination of
ground water if not properly managed. Therefore, any time sewage sludge is going to be
applied at greater than agronomic rates, the land applier must first seek approval from the
permitting authority. In some instances, the permitting authority may require a specific permit
for this practice.
Domestic septage also contains beneficial characteristics as a soil enhancer and can be land
applied. Although domestic septage is considered sewage sludge, its physical characteristics are
different from those of sewage sludge generated at a wastewater treatment plant. As such, some
of the Part 503 requirements for the land application of domestic septage are different from the
land application requirements found in this manual and are therefore addressed in a separate
document. For further information on how to comply with Part 503 when applying domestic
septage to agricultural land, forests, or reclamation sites, refer to Domestic Septage Regulatory
Guidance: A Guide to the EPA 503 Rule (EPA, 1993). Contact the Office of Water Resources
Center or the National Small Flows Clearinghouse to obtain a copy.
Surface disposal is another regulated use or disposal practice for sewage sludge that is similar
to land application in that it entails the placement of sewage sludge on the land. The main
difference between the two is that in the case of surface disposal, sewage sludge is placed on the
land for the purpose of final disposal, without regard for the soil enhancing qualities of the
sewage sludge.
1.2 The Land Applier and Factors for Determining His or Her
Responsibilities Under Part 503
Land appliers are persons who apply sewage sludge to the land to condition the soil and/or to
fertilize crops or vegetation grown in the soil. The term "land applier" includes persons
applying large quantities of bulk sewage sludge to areas such as agricultural land as well as
persons applying smaller quantities of sludge, usually distributed in bags, to a lawn or home
garden. Thus, the definition of land applier is very broad and includes both those persons
-------
Introduction Section One
applying sewage sludge to the land in large quantities and home owners who apply sewage
sludge in small quantities.
Although the definition of "land applier" encompasses a wide range of persons, not all land
appliers are required to comply with the same number and variety of Part 503 land application
requirements. Which appliers will need to comply with what requirements depends upon several
important factors, the most prominent of which are sewage sludge quality, and whether the
sewage sludge is provided to the land applier in bulk form or in a bag or other container.
Sewage Sludge Quality
The Part 503 regulation focuses on the following three parameters as a basis for determining
sewage sludge quality:
• The presence of pollutants (arsenic, cadmium, chromium, copper, lead, mercury,
molybdenum, nickel, selenium, and zinc)
• The presence of pathogens (e.g., bacteria, viruses, parasites)
• The sewage sludge's attractiveness to vectors (e.g., rodents, flies, mosquitoes).
Sewage sludge quality varies from municipality to municipality with respect to these three
parameters. Determining sewage sludge quality is usually the sole responsibility of the person
who initially prepares the sludge, and not of the land applier. However, because sewage sludge
quality plays such a significant role in determining land application requirements, a portion of
this document is dedicated to the explanation of this topic.
To accommodate this variability and ensure the protection of human health and the environment,
Part 503 has established several sets of sewage sludge quality requirements for each of the three
parameters, with corresponding requirements to be implemented by the land applier. In this
way, varying qualities of sewage sludge can be land applied while still providing protection to
human health and the environment.
-------
Section One Introduction
Sewage sludge that meets the most stringent limits for all three of the above sewage sludge
quality parameters is referred to as Exceptional Quality (EQ) sewage sludge. Sewage sludge
that does not meet the most stringent limits for any or all three of the sludge quality parameters
is referred to as non-EQ sewage sludge.
EQ sludge is considered comparable to standard fertilizer products. Therefore land appliers
of EQ sewage sludge have no requirements to meet under the Rule. For non-EQ sludges,
however, Part 503 imposes a larger number and variety of requirements depending upon the
degree to which the sludge quality diverges from EQ.
Sewage sludge or material derived from sewage sludge Is classified as Exceptional
Quality (EQ) if it meets the following requirements:
Pollutants— Both Ceiling Concentrations (40 CFR 503.13(b)(l)) and Pollutant
Concentrations (40 CFR 503.13(b)(3))
Pathogens—One of the Class A Pathogen Reduction Alternatives (40 CFR 503,32(a))
Attractiveness to Vectors— One of the Vector Attraction Reduction Options that are
accomplished during sewage sludge processing/treatment (options i-8) (40 CFR
503.33(b)(l)-(8)).
Sewage sludge or material derived from sewage sludge is classified as non-EQ if it
exceeds one, two, or all three of the requirements that define EQ sewage sludge as
specified above and in the Rule,
When sewage sludge is non-EQ, Part 503 imposes requirements for both the sewage sludge and
the land application site to ensure the same level of protection for human health and the
environment as provided by EQ sewage sludge.
-------
Introduction Section One
Methods of Sewage Sludge Distribution to the Land Applier
The number and type of requirements associated with the land application of sewage sludge are
affected not only by sludge quality (pollutant levels, level of pathogen reduction, and
attractiveness to vectors), but also by the method of distribution, that is, whether the sludge is
applied in bulk form or is placed in a bag or other container for application to the land.
The method of distribution is important because it is an indication of the relative quantity of
sewage sludge being applied. Bulk sewage sludge is usually applied in large quantities, whereas
sewage sludge sold or given away in bags or other containers is usually applied in smaller
quantities. Some types of requirements can be easily implemented by large quantity land
appliers, while the same requirement can be impractical and cumbersome for the small quantity
appliers.
Most of the requirements for land appliers under Part 503 affect appliers of bulk, non-EQ
sewage sludge. Appliers of sewage sludge sold or given away in a bag or other container need
only read and adhere to instructions on the label or information sheet accompanying the sewage
sludge product; they are not subject to management practices, pollutant limits, pathogen and
vector attraction reduction requirements, or recordkeeping and reporting requirements.
Because the probability of close human contact is very high when sewage sludge is distributed
for use by the general public in bags or other containers, only material that is EQ for all three
sludge quality parameters, or that at a minimum meets EQ quality for pathogen reduction and
vector attraction reduction, can be distributed in bags or other containers.
Sewage sludge that does not attain EQ quality for at least these two parameters can only be
distributed and applied in bulk. This is because there are a number of site restrictions and other
land application requirements that are necessary for the proper application of sewage sludge of
this quality, yet would be impractical for small appliers such as homeowners to implement.
-------
Section One Introduction
Consequences of Changing the Quality of Sewage Sludge
If the applier changes the quality of the sewage sludge prior to application, the change may
influence the number of requirements with which the land applier must comply.
Generally, it is the responsibility of the person who prepares the sewage sludge to monitor and
certify sewage sludge quality. In some cases, the person who prepares the sewage sludge also
land applies it and is clearly responsible for meeting the requirements for sewage sludge
preparation in addition to those for land application. If the land applier alters the sewage sludge
quality so that the quality of the sewage sludge being applied is different from what was received
from the preparer, the land applier becomes a preparer and assumes responsibility for monitoring
and certifying its quality (e.g., certification of sludge quality relative to pollutant limits, level
of pathogen reduction, and level of vector attraction reduction).
Mixing bulk EQ sewage sludge with other EQ sewage sludges, composting it, or mixing it with
other non 503 regulated substances such as bulking agents, wood chips, or substances to enhance
the beneficial characteristics of the sludge as a fertilizer theoretically results in a mixture that
is still EQ in quality. Therefore, in these situations, the land applier would not assume
responsibility for re-evaluating its quality.
However, sludge quality is considered to have been changed when bulk non-EQ sewage sludge
is accepted from several sources and mixed prior to land application, when bulk non-EQ sewage
sludge is mixed with other additives such as wood chips\bulking agents or substances to enhance
the characteristics of sludge as a fertilizer, or when bulk EQ sewage sludge is mixed with non-
EQ sludge. In these situations, the resulting quality of the mixtures must be ascertained to know
how to correctly land apply. For further information regarding these requirements, please refer
to the document Preparing Sewage Sludge for Land Application or Surface Disposal-A Guide
for Preparers on the Monitoring, Recordkeeping, and Reporting Requirements of the Federal
Standards for the Use or Disposal of Sewage Sludge Management, 40 CFR Part 503 (EPA,
1993).

Introduction Section One
1.3 Glossary of Terms
Agricultural land- Land on which a food, feed, or fiber crop is grown. This includes range
land or land used as pasture.
Agronomic rate- The whole sludge application rate designed to (1) provide the amount of
nitrogen needed by a crop or vegetation grown on the land and (2) minimize the amount of
nitrogen in the sewage sludge that passes below the root zone of the crop or vegetation grown
on the land to the ground water.
Annual pollutant loading rate (APLR)- The maximum amount of a pollutant that can be
applied to a unit area of land during a 365-day period. This term describes pollutant limits for
sewage sludge that is given away or sold in a bag or other container for application to the land.
Annual whole sludge application rate- The maximum amount of a sewage sludge on a dry
weight basis that can be applied to a land application site during a 365-day (1-year) period.
Bulk sewage sludge- Sewage sludge that is not sold or given away in a bag or other container
for application to the land.
Bagged sewage sludge- Sewage sludge that is sold or given away in a bag or other container
(i.e., either an open or closed receptacle containing 1 metric ton or less of sewage sludge).
Class I sludge management facility- Publicly owned treatment works (POTWs), required to
have an approved pretreatment program under 40 CFR 403.8(a), including any POTW located
in a State that has elected to assume local pretreatment program responsibilities under 40 CFR
403.10(e). In addition, the Regional Administrator or, in the case of approved State programs,
the Regional Administrator in conjunction with the State Director, has the discretion to designate
any treatment works treating domestic sewage (TWTDS) as a Class I sludge management
facility.
Cumulative pollutant loading rate (CPLR)- The maximum amount of an inorganic pollutant
that can be applied to an area of land. This term applies to bulk sewage sludge that is land
applied.
Domestic septage- Either a liquid or solid material removed from a septic tank, cesspool,
portable toilet, Type III marine sanitation device, or similar treatment works that receives only
domestic sewage. This does not include septage resulting from treatment of wastewater with a
commercial or industrial component.
Exceptional Quality sewage sludge- Sewage sludge that meets the most stringent limits for the
three sludge quality parameters. In gauging sewage sludge quality, EPA determined that three
main parameters of concern should be considered: (1) pollutant levels, (2) the relative presence
or absence of pathogenic organisms, such as salmonella and E-Coli bacteria, enteric viruses, or
viable helminth ova, and (3) the degree of attractiveness of the sewage sludge to vectors, such
as flies, rats, and mosquitoes, that could potentially come in contact with pathogenic organisms
and spread disease. Given these three variables, there can be a number of possible sewage
-------
Section One Introduction
sludge qualities. The term Exceptional Quality (EQ), which does not appear in the Part 503
regulation, is used to describe sewage sludge that meets the highest quality for all three of these
Sewage sludge quality parameters (i.e., ceiling concentrations and pollutant concentrations in
503.13 for metals, one of the Class A pathogen reduction alternatives, and one of the sewage
sludge processing vector attraction reduction options 1 through 8).
Feed crop- Crops produced primarily for consumption by animals. These include, but are not
limited to, corn and grass. For a crop to be considered a feed crop, it has to be produced for
consumption by animals (e.g., grass grown to prevent erosion or to stabilize an area is not
considered a feed crop).
Fiber crop- Crops, such as flax and cotton, that were included in Part 503 because products
from these crops (e.g., cotton seed oil) may be consumed by humans.
Food crop- Crops consumed by humans. These include, but are not limited to, fruits, grains,
vegetables, and tobacco.
Forest land- Tract of land thick with trees and underbrush.
Preparer- Either the person who generates sewage sludge during the treatment of domestic
sewage in a treatment works or the person who derives a material from sewage sludge.
Land application site- An area of land on which sewage sludge is applied to condition the soil
or to fertilize crops or vegetation grown in the soil.
Pasture- Land on which animals feed directly on feed crops such as legumes, grasses, or grain
stubble.
Public contact site- Land with a high potential for contact by the public, including public parks,
ball fields, cemeteries, nurseries, turf farms, and golf courses.
Range land- Open land with indigenous vegetation.
Reclamation site- Drastically disturbed land, such as strip mines and construction sites, that is
reclaimed using sewage sludge.
Sewage sludge- The solid, semi-solid, or liquid residue generated during the treatment of
domestic sewage in a treatment works. Sewage sludge includes, but is not limited to, domestic
septage, scum, and solids removed during primary, secondary, or advanced wastewater treatment
processes. The definition of sewage sludge also includes a material derived from sewage sludge
(i.e., sewage sludge whose quality is changed either through further treatment or through mixing
with other materials).
Treatment works- Federally owned, publicly owned, or privately owned device or system used
to treat (including recycle or reclaim) either domestic sewage or a combination of domestic
sewage and industrial waste of a liquid nature.
-------
Introduction Section One
Treatment works treating domestic sewage- A POTW or other sewage sludge or wastewater
treatment system or device, regardless of ownership used in the storage, treatment, recycling,
and reclamation of municipal or domestic sewage, including land dedicated for the disposal of
sewage sludge.

Section Two Requirements for Land Application
2. SUMMARY OF PART 503 REQUIREMENTS
FOR LAND APPLICATION
This section summarizes the Part 503 requirements for the land application of sewage sludge.
Part 503 contains seven basic types of requirements for sewage sludge that is land applied:
• General requirements
• Pollutant limits
• Operational standards for pathogen and vector attraction reduction
• Management practices
• Frequency of monitoring
• Recordkeeping
• Reporting.
As has been previously mentioned, the number of requirements for the land applier is determined
by the quality of the sewage sludge being land applied, in addition to whether the sewage sludge
is land applied in bulk form or sold or given away in a bag or other container for application
to the land.
2.1 General Requirements (40 CFR 503.12)
The general requirements, listed in Exhibit 2, establish a number of general ground rules for the
land application of sewage sludge. Most requirements are for bulk non-EQ sewage sludge. The
requirements for land appliers of bulk non-EQ sewage sludge address the:
Transfer of sufficient information (referred to as Notice and Necessary Information in
Part 503.12) among the preparer, land applier, landowner, and permitting authority
Tracking of cumulative pollutant loadings from sewage sludge that is non-EQ for
pollutants
Movement of sewage sludge across State lines.
11
-------
Requirements for Land Application Section Two
Exhibit 2. General Requirements for Land Application of Sewage Sludge
(a) No person shall apply sewage sludge to the land except in accordance with the Part 503 land application requirements.
(b) No person shall apply bulk sewage sludge that is non-EQ for pollutants (i.e., subject to cumulative pollutant
loading rates in 503.13(b)(2)) to agricultural land, forest, a public contact site, or a reclamation site if any of the
cumulative pollutant loading rates in 503.13(b)(2) has been reached.
(c) No person shall apply domestic septage to agricultural land, forest, or a reclamation site during a 365-day period
if the annual application rate in 503.13(c) has been reached during that period.
(d) The person who prepares bulk sewage sludge that is applied to agricultural land, forests, areas where the potential
for contact with the public is high (i.e., public contact site) or a reclamation site shall provide the person who
applies the bulk sewage sludge written notification of the concentration of total nitrogen (as N on a dry weight
basis) in the bulk sewage sludge.
(e)(l) The person who applies sewage sludge to the land shall obtain information needed to comply with applicable Part
503 requirements.
(e)(2)(i) Before bulk sewage sludge that is subject to cumulative pollutant loading rates (CPLRs) in 503.13(b)(2) is applied
to the land, the person who proposes to apply the bulk sewage sludge shall contact the permitting authority for the
State in which the bulk sewage sludge is being applied, to determine whether, bulk sewage sludge subject to the
cumulative pollutant loading rates in 503.13(b)(2) has been applied to the site since July 20, 1993.
(ii) If bulk sewage sludge subject to CPLRs has not been applied to the site since July 20, 1993, the cumulative
amount of each pollutant listed in Table 2 of 503.13 may be applied to the site in accordance with 503.13(a)(2)(i).
(iii) If bulk sewage sludge subject to CPLRs in 503.13(b)(2) has been applied to the site since July 20, 1993, and the
cumulative amount of each pollutant applied to the site since that date is known, the cumulative amount of each
pollutant applied to the site shall be used to determine the additional amount of each pollutant that can be applied
to the site in accordance with 503.13(a)(2)(i).
(iv) If bulk sewage sludge subject to CPLRs in 503.13(b)(2) has been applied to the site since July 20, 1993, and the
cumulative amount of each pollutant applied to the site since that date is not known, sewage sludge subject to
CPLRs may no longer be applied to the site.
(f) A person who prepares bulk sewage sludge shall provide the person who applies the bulk sewage sludge notice
and necessary information to comply with applicable Part 503 requirements.
(g) When the person who prepares sewage sludge gives the material to another person who prepares sewage sludge,
the person who provides the sewage sludge shall provide to the person who receives sewage sludge notice and
necessary information to comply with the applicable Part 503 requirements.
The person who applies bulk sewage sludge to the land shall provide the owner/leaseholder of the land on which
the bulk sewage sludge is applied notice and necessary information to comply with applicable Part 503
requirements
Any person who prepares bulk sewage sludge that is applied to land in a State other than the State in which the
bulk sewage sludge is prepared, shall provide written notice, prior to the initial application of bulk sewage sludge
to the land application site by the applier, to the permitting authority for the State in which the bulk sewage
sludge is proposed to be applied. The notice must include:
(1) The location by either street address or latitude/longitude, of each land application site.
(2) The approximate time period in which the bulk sewage sludge will be applied to the site.
(3) The name, address, telephone number, and National Pollutant Discharge Elimination System permit number
(if appropriate) for the person who prepares the bulk sewage sludge.
(4) The name, address, telephone number, and National Pollutant Discharge Elimination System permit number
(if appropriate) for the person who will apply the bulk sewage sludge.
Any person who applies bulk sewage sludge subject to the cumulative pollutant loading rates in 503.13(b)(2) to
the land shall provide written notice, prior to the initial application of the bulk sewage sludge to the application
site by the applier, to the permitting authority for the State in which the bulk sewage sludge will be applied, and
the permitting authority shall retain and provide access to the notice. The notice must include:
(1) The location, by either street address or latitude/longitude, of each land application site.
(2) The name, address, and National Pollutant Discharge Elimination System permit number (if appropriate) of
the person who will apply the bulk sewage sludge.
12
-------
Section Two Requirements for Land Application
Notice and Necessary Information
If the land applier is not the same person who prepared the sewage sludge, the person preparing
the bulk non-EQ sewage sludge is responsible for giving the land applier documentation on the
quality of the sewage sludge. This information must be obtained prior to applying the sludge
to land. In this case, the preparer must provide the land applier with necessary information on
how to comply with Part 503 (see Appendix A, Notice and Necessary Information) to ensure that
the land applier is fully aware of his or her responsibilities and that the sewage sludge is
properly applied. In turn, the land applier is required to obtain this information from the
preparer prior to land application if the preparer does not readily offer it.
The land applier will need to obtain the following information, prior to land application, from
the preparer:
• Pollutant concentrations
• Nitrogen concentrations
• Class of pathogen reduction level achieved
• Vector attraction reduction option achieved, if any.
In addition, the land applier is required to provide the landowner/leaseholder with any
information necessary to comply with the land application requirements. For example, if sewage
sludge that is non-EQ due to pathogens is applied, the land applier, at a minimum, must inform
the landowner/leaseholder of the applicable site restrictions. The land applier may also want to
provide to the landowner/leaseholder the sewage sludge quality information, including nitrogen
content, with documentation that sewage sludge has been applied to the land in compliance with
all relevant Part 503 requirements. Appendix A contains a sample format for providing notice
and necessary information to the landowner/leaseholder.

Requirements for Land Application Section Two
Tracking of Cumulative Pollutant Loadings Rate
If bulk sewage sludge being land applied is non-EQ due to pollutant levels, the land applier is
required to comply with cumulative pollutant loading rates (CPLRs). Two general requirements
apply specifically to the land application of sewage sludge subject to CPLRs. (CPLRs are
described in Section 2.2.) The first general requirement facilitates tracking the amount of each
pollutant applied to land application sites where sewage sludge of this quality has been applied.
The second general requirement ensures that previous applications of sewage sludge subject to
CPLRs are considered before additional applications.
The land applier must notify the permitting authority in the State where the sludge will be
applied of his or her intent to apply sewage sludge to a particular site prior to initial land
application. This notification must include the location of each land application site and the
name, address, telephone number, and National Pollutant Discharge Elimination System
(NPDES) permit number (if appropriate) of the land applier.
In all situations where bulk sewage sludge that is non-EQ due to pollutant levels is land applied,
land appliers must consult the permitting authority, prior to initiating land application, to
determine whether or not there have been past applications of sewage sludge subject to CPLRs
since July 20, 1993. If sewage sludge of this quality was not applied to the site previously, the
land applier must begin keeping records of the cumulative loadings of each of the 10 regulated
pollutants. If multiple land appliers are applying sewage sludge of this quality to the same site,
they must make their sewage sludge application data available to the other appliers and
coordinate the tracking of cumulative loadings to ensure that the CPLRs are not exceeded. If
sewage sludge of this quality was applied to the site since July 20, 1993, the land applier must
find out the amount of each regulated pollutant that was applied and subtract those loadings from
the allowable CPLR for each pollutant to ensure that additional applications will not exceed the
CPLR for any of the pollutants regulated under Part 503. If the levels of pollutants were not
documented in the previous application and the applier is unable to take these past loadings into
account, no additional sewage sludge that is non-EQ due to pollutants can be applied to the site.
Exhibit 3 outlines the procedures for determining whether sewage sludge subject to CPLRs can
be applied to a land application site that has had previous sewage sludge applications. Land

Requirements for Land Application Section Two
appliers are encouraged to contact the U.S. Environmental Protection Agency (EPA) Regional
Water Management Division for assistance in tracking CPLR applications.
Movement of Bulk Sewage Sludge Across State Lines (see 503.12(i))
When the land applier determines that bulk non-EQ sewage sludge is to be land applied in a
State other than the State in which it was generated, he or she should notify the preparer
immediately. The preparer is responsible for notifying the permitting authority in the State
where the material is to be applied prior to the initial application to a site. Before the initial
application, the applier should contact the preparer to confirm that this notification has been
submitted.
In the case of interstate land application of sewage sludge that is non-EQ due to pollutant levels
(i.e., subject to CPLRs), the land applier, as well as the preparer, must send written notice to
the permitting authority in the State where the sewage sludge is to be applied prior to the initial
application of sewage sludge to the site.
2.2 Pollutant Limits (40 CFR 503.13)
The first parameter of the three that must be assessed to determine overall sludge quality is the
level of pollutants (metals). Some sewage sludge contains negligible levels of pollutants while
others contain higher levels. To ensure that human health and the environment are protected
equally while still allowing the land application of sewage sludges of variable quality, Part 503
provides the following four sets of pollutant limits.
Ceiling Concentrations
Ceiling concentrations apply to all land applied sewage sludge (bulk sewage sludge and sewage
sludge sold or given away in a bag or other container). Ceiling concentrations (milligrams per
kilogram, on a dry weight basis), given in Exhibit 4, establish the maximum concentration of
each pollutant that sewage sludge can contain and still be land applied. Each sample of sewage
sludge analyzed must meet the ceiling concentration limits. These limits are applied as
maximum, never to be exceeded values, not as averages. Sewage sludge that does not meet

-------
Requirements for Land Application Section Two
these specified thresholds for any or all of the 10 regulated pollutants must be used of disposed
of in some other way; it cannot be land applied. Once it is determined that sewage sludge meets
ceiling concentrations, the preparer must determine which one of the remaining three sets of
pollutant limits applies to his or her sewage sludge.
Pollutant Concentration Limits
Sewage sludge meeting pollutant concentration limits achieves one of three levels of quality
necessary for EQ status. The land applier has no land application requirements relative to
pollutants for sewage sludge meeting these limits. Pollutant concentration limits are monthly
average values in milligrams per kilogram on a dry weight basis (see Exhibit 4).
Cumulative Pollutant Loadings
CPLRs apply to bulk sludge that meets ceiling concentration limits but does not meet pollutant
concentration limits for any or all of the 10 regulated pollutants (see Exhibit 4). CPLRs
establish the maximum amount (mass) of each regulated pollutant that can be applied to a site
(kilogram per hectare) during the life of the site. (For purposes of determining compliance with
Part 503, a "site" is considered to be a parcel of land on which sewage sludge has been or will
be applied.) The greatest number of recordkeeping and reporting requirements for the land
applier pertains to sewage sludge of this quality.
When applying sewage sludge that is subject to CPLRs, the land applier is required to keep
records of the amounts of each regulated pollutant applied to the site over time to ensure that
the maximum allowable amounts are not exceeded. This is calculated by determining the amount
of each pollutant applied to the land in previous sewage sludge applications and subtracting this
amount from the CPLR for each pollutant (see Appendix B). The applier then must maintain
records of the amounts of each pollutant applied to the site in sewage sludge, including the
amounts applied in previous applications occurring after July 20, 1993. If several land appliers
are applying sewage sludge on the same site, all the land appliers are responsible for
communicating with each other to ensure that the CPLRs are not exceeded.
18
-------
Section Two Requirements for Land Application
Annual Pollutant Loading Rates
APLRs apply to sewage sludge that meets ceiling concentrations, but does not meet pollutant
concentration limits (see Exhibit 4), and is to be sold or given away in a bag or other
container for application to the land. APLRs establish the maximum amount (mass) of
pollutants in sewage sludge that can be applied to a site during a 3 65-day period. APLRs
instead of CPLRs are applied to these sludges because sewage sludge sold or given away in a
bag or other container is commonly used by homeowners and it would be impractical to expect
homeowners to track cumulative pollutant loadings. APLRs, therefore, have been designed so
that the applier of bagged sewage sludge of this quality does not have to track cumulative
pollutant loadings.
Appliers that use sewage sludge sold or given away in a bag or other container have no
requirements under the Part 503 regulation except to follow the instructions provided with the
sewage sludge. For non-EQ sewage sludge that is sold or given away in a bag or other
container, the person who prepares the sewage sludge is required to determine the appropriate
application rate based on the sludge quality and print it on a label or information sheet for the
applier.
Note that only EQ sewage sludge or sewage sludge that is non-EQ only due to pollutant levels
can be sold or given away in a bag or other container. Bagged sewage sludge must, at a
minimum, meet the highest quality requirements for pathogen reduction and one of the eight
vector attraction reduction options that involve treatment of the sewage sludge. Sewage sludge
that does not meet the highest quality for at least these two sludge quality parameters cannot be
sold or given away in a bag or other container for application to the land.
2.3 Pathogen Reduction (40 CFR 503.15 and 40 CFR 503.32)
The second parameter in determining sewage sludge quality is the presence or absence of
pathogens (i.e., disease causing organisms), such as Salmonella bacteria, enteric viruses, and
viable helminth ova. The preparer is responsible for monitoring and certifying the sewage
19
-------
Requirements for Land Application
Section Two
sludge for pathogen reduction. If the land applier chooses, however, he or she may at any time
verify this information independently (see Appendix C, Monitoring).
The Part 503 regulation contains two classes of pathogen reduction: Class A and Class B.
Class A pathogen reduction alternatives render the sewage sludge virtually pathogen free after
treatment. Class B pathogen reduction alternatives significantly reduce but do not eliminate all
pathogens. Land appliers who apply sewage sludge that is certified by the preparer as Class
A have no requirements relative to pathogens. If the sewage sludge is Class B, site restrictions
must be imposed to allow time for natural processes to further reduce pathogen levels.
Site restrictions for Class B address (1) public access to the land application site and (2) crop
harvest and grazing of animals at the site. Public access must be restricted for at least 30 days
on all land application sites that receive Class B sewage sludge.
If the site is frequently used by the public or the potential for public contact is high, public
access must be restricted for 1 year after Class B sewage sludge is applied. Exhibit 5 illustrates
the different public access waiting periods.
Exhibit 5. Public Access Restrictions for Land Application of Class B Sewage Sludge
Land has high potential for public exposure:
• Parks
• Playgrounds
• Golf courses
No
Yes
Public access must be restricted for 1 year
after sewage sludge application
Land has low potential for public exposure:
• Farmland in rural areas
• Remote lands
• Securely fenced land
Yes
Public access must be restricted for 30 days
after sewage sludge application
In addition to public access control, several other site restrictions may apply, depending on the
uses of the land application site. For example, if food crops are grown at the site, certain
20
-------
Section Two Requirements for Land Application
waiting periods must be observed prior to harvest. Similarly, waiting periods must be observed
for sites where feed and fiber crops, as well as turf, are grown and where animals are grazed.
Exhibit 6 provides a flowchart linking the land use with site restrictions. When the land
application site is not used for any of the activities shown in Exhibit 6, the only site restriction
that applies is public access control.
The site restrictions to control public access or crop harvest and grazing animals must be
implemented by either the land applier or the landowner/leaseholder. At a minimum, the land
applier must provide the landowner/leaseholder with a list of these restrictions and inform him
or her that these restrictions must be met for each site where Class B sewage sludge is applied.
If it is agreed that the land applier will implement site restrictions, the land applier must certify
that they have been met and maintain this certification in his or her records for a period of 5
years. If the land applier and the land owner agree that the land owner will implement the
appropriate restrictions, the land applier must provide the land owner with a list of the
restrictions and certify that the land owner was appropriately informed. (Refer to Appendix A,
Notice and Necessary Information, for an example notification format.)
In summary, the following site restrictions associated with the application of Class B sewage
sludge are necessary to provide the same level of protection to public health and the environment
as is provided by Class A sewage sludge:
Public access to land with a high potential for public exposure shall be restricted for
1 year after sewage sludge application.
Public access to land with a low potential for public exposure shall be restricted for 30
days after sewage sludge application.
Food crops, feed crops, or fiber crops shall not be harvested for 30 days after sewage
sludge is applied.
Food crops with harvested parts that touch the sewage sludge/soil mixture and are
totally above the land surface (e.g., melons, cucumbers, squash) shall not be harvested
for 14 months after application of sewage sludge.

Section Two Requirements for Land Application
• Food crops with harvested parts below the surface of the land (e.g., root crops, such
as potatoes, carrots, radishes) shall not be harvested for 20 months after application
when the sewage sludge is not incorporated into the soil or remains on the soil surface
for 4 or more months prior to incorporation into the soil.
• Food crops with harvested parts below the surface (e.g., root crops, such as potatoes,
carrots, radishes) shall not be harvested for 38 months if the sewage sludge is
incorporated into the soil within 4 months after sewage sludge application.
• Animals shall not be grazed on a site for 30 days after sewage sludge application.
• Turf shall not be harvested for 1 year after sewage sludge application if the turf is
placed on land with a high potential for public exposure or on a lawn, unless otherwise
specified by the permitting authority.
2.4 Vector Attraction Reduction (40 CFR 503.15 and 40 CFR 503.33)
The degree of attractiveness of sewage sludge to vectors is the third parameter of sewage sludge
quality. Vectors are animals and insects (e.g., rodents, flies, birds) that might be attracted to
sewage sludge and, therefore, could transmit pathogenic organisms (if any are present) to
humans. One of the 10 options provided in the regulation to reduce vector attractiveness must
be met if sewage sludge is to be applied to the land. The 10 vector attraction reduction options
fall into two categories-treatment options (options 1 through 8) and barrier options (options 9
and 10). Treatment options are undertaken by the sewage sludge preparer. If any one of the
treatment options is performed by the preparer, the land applier has no requirements relative to
vector attraction reduction. If one of the treatment options is not performed by the preparer,
the land applier is responsible for implementing and certifying compliance with either one of the
following barrier options (which use soil as a barrier between the sewage sludge and any vectors
that might be present):
. Vector Attraction Reduction Option 9 (40 CFR 503.33)
Sewage sludge shall be injected below the surface of the land.
- No significant amount of the sewage sludge shall be present on the land surface
within 1 hour after the sewage sludge is injected.
When sewage sludge that is injected below the surface of the land is Class A for
pathogens, the sewage sludge shall be injected below the land surface within 8
23
-------
Requirements for Land Application Section Two
hours after being discharged from the pathogen treatment process (to prevent
regrowth of Salmonella bacteria).
. Vector Attraction Reduction Option 10 (40 CFR 503.33)
Sewage sludge applied to the land shall be incorporated into the soil within 6 hours
after application to the land.
When sewage sludge that is incorporated into the soil is Class A for pathogens, the
sewage sludge shall be applied to the land within 8 hours after being discharged
from the pathogen treatment process.
2.5 Management Practices (40 CFR 503.14)
Management practices also help ensure that sewage sludge is applied in a manner that is
protective of human health and environment. Most management practices govern the way in
which bulk non-EQ sewage sludge is applied to the land and, in some cases, may prevent the
application from occurring on a specific parcel. Management practices are applicable to the land
application of bulk non-EQ sewage sludge in the following areas:
• Threatened or Endangered species
• Flooded, frozen, or snow-covered land
• Distance to waters of the United States
• Agronomic rates.
Only one management practice applies to sewage sludge sold or given away in a bag or other
container. A label or information sheet must be provided with the sludge indicating the
appropriate application rate for the quality of the sludge. The applier is required to read and
follow correctly these instructions.
Threatened or Endangered Species
Part 503 prohibits the application of bulk non-EQ sewage sludge to the land if it is likely to
adversely affect threatened or endangered species or their designated critical habitat. Any direct
or indirect action that reduces the likelihood of survival and recovery of an threatened or
endangered species is considered an "adverse effect. " Critical habitat is any place where an
24
-------
Section Two Requirements for Land Application
threatened or endangered species lives and grows during any stage in its life cycle. The U.S.
Department of Interior, Fish and Wildlife Service (FWS) publishes a list of threatened or
endangered species at 50 CFR 17.11 and 17.12.
Application of sewage sludge to land that is subjected to normal tillage, cropping, and grazing
practices, mining, forestry and other activities that, by their nature, turn the soil and impact
vegetation is not likely to cause any increase in negative impact on endangered species and in
fact may be beneficial because of the nutritive and soil building properties of sewage sludge.
However, it is the responsibility of the land applier to determine whether the application of
sludge might cause an adverse effect on threatened or endangered species or their critical
habitats. The Part 503 rule requires the land applier to certify that the applicable management
practices have been met, including the requirement concerning threatened or endangered species,
and that records be kept indicating how the applicable management practices have been met.
To comply with this management practice, the land applier should consult with FWS to
determine whether any threatened or endangered species or designated critical habitats are
present at the site. The land applier should retain all documentation to demonstrate that the site
was evaluated for potential effects on threatened or endangered species and/or their habitat and
that necessary protective measures were identified and implemented. The telephone number of
the appropriate local FWS field office can be obtained from the FWS regional offices, listed in
Appendix D.
Flooded. Frozen, or Snow-Covered Land
Part 503 does not prohibit the application of bulk non-EQ sewage sludge to flooded, frozen, or
snow-covered lands. The regulation does, however, state that bulk sewage sludge applied to
these lands may not enter wetlands or other waters of the United States, unless specifically
authorized by a permit issued under Sections 402 or 404 of the Clean Water Act. EPA Regional
Sludge Coordinators can be contacted for further information.
Prior to applying sewage sludge to flooded, frozen, or snow-covered lands, the land applier
should ensure that proper runoff control measures are in place to prevent sewage sludge from
25
-------
Requirements for Land Application Section Two
entering waters of the United States. Some common runoff controls include slope restrictions,
buffer zones/filter strips, tillage to create a roughened soil surface, crop residue or vegetation
requirements, berms, dikes, silt fences, diversions, sediment basins and terraces.
Distance to Waters of the United States
Part 503 prohibits the application of bulk non-EQ sewage sludge on agricultural land, forest, or
a reclamation site that is within 10 meters (approximately 33 feet) of any waters of the United
States (i.e., intermittent flowing streams as well as creeks, rivers, wetlands, or lakes) unless
otherwise specified by the permitting authority. This lo-meter buffer zone serves as a barrier
against sewage sludge entering water bodies. A permitting authority may give approval prior
to application of sewage sludge to land that is less than 10 meters from waters of the United
States if the application is expected to enhance the local environment. For example, the
application of bulk sewage sludge to revegetate a stream bank suffering from severe erosion may
be approved by the permitting authority if the risk from not stabilizing the bank with sewage
sludge is greater than the risk of sewage sludge reaching the stream.
Many land appliers employ additional management practices to minimize runoff and ponding of
sewage sludge. Common management practices include conservation tillage, infiltration
trenches, diversions, filter strips, terraces, grassed waterways, sediment basins, and detention
ponds.
Agronomic Rate
Part 503 requires that bulk non-EQ sewage sludge be applied to a site at a rate that is equal to
or less than the agronomic rate for the site. The agronomic rate is the whole sewage sludge
application rate (on a dry weight basis) that is designed to provide the amount of nitrogen needed
by the crop or vegetation and yet minimize the amount of nitrogen that passes below the root
zone of the crop or vegetation to the ground water. A sewage sludge application rate exceeding
the agronomic rate could result in nitrate contamination of the ground water. Sewage sludge
should be applied as close to the time of maximum nutrient uptake by crops as feasible.
26
-------
Section Two Requirements for Land Application
Although the preparer is required to supply the land applier with the nitrogen content of the
sewage sludge, the land applier will be responsible for ensuring that the sewage sludge is applied
at less than or equal to the agronomic rate for the site. Appendix E contains worksheets to help
calculate the annual whole sewage sludge application rate consistent with the agronomic rate for
the vegetation being grown. These worksheets provide only one approach for calculating the
agronomic rate; other approaches can be used. Many State sludge management programs
and/or local agricultural extension agents have developed their own methods for calculating the
agronomic rate. Assistance in calculating the agronomic rate should be available from a
knowledgeable person such as the local extension agent or soil testing department at the land
grant university in each State.
In some cases, the permitting authority may specifically authorize the application of sewage
sludge to a reclamation site at a rate that exceeds the agronomic rate. Such cases may include
but are not limited to, reclamation sites where there is no potential for nitrate to leach down to
the ground water or where the ground water is not capable of being used as a potable water
supply (assuming that the State has no antidegradation policy that would apply to these waters).
Typically, sewage sludge will be applied at a rate that exceeds the agronomic rate only once,
to improve the physical properties of the soil and supply nitrogen and other nutrients. Once a
vegetative cover has been established, future applications of sewage sludge should be limited to
the agronomic rate of the vegetation grown.
2.6 Monitoring (40 CFR 503.16)
The person who prepares sewage sludge must monitor sludge quality. As mentioned in the
section on general requirements, the land applier must obtain information from the preparer on
the pollutant concentrations in bulk non-EQ sewage sludge. The applier of bulk sewage sludge
may want to independently verify sewage sludge quality through additional testing, although this
is not required. By independently testing the sewage sludge using EPA-approved procedures,
the applier can check the reliability of the information from the preparer. Appendix C contains
guidance for monitoring the quality of sewage sludge.
27
-------
Requirements for Land Application Section Two
To meet the requirement of providing the land applier with the pollutant concentration
information, the preparer may negotiate with the land applier and designate the land applier as
the party responsible for sampling and/or testing the preparer's sewage sludge. The land applier
will need to keep records documenting results. However, the preparer is still responsible for
documenting the. sewage sludge quality.
2.7 Recordkeeping (40 CFR 503.17)
Recordkeeping requirements for the land application of sewage sludge are divided into
responsibilities for the sewage sludge preparer and those for the land applier. All preparers are
required to keep records on sludge quality regardless of whether the sewage sludge is EQ or
non-EQ. Land appliers are only required to keep records for sludge quality if they change the
original quality of the sludge and therefore meet the definition of a preparer. Otherwise, land
appliers are only required to keep records when applying bulk sewage sludge that is non-EQ for
one, two, or all three of the sludge quality parameters.
Some recordkeeping requirements for land appliers vary depending on the sewage sludge quality.
However, all appliers of bulk non-EQ sewage sludge are responsible for documenting
implementation of the applicable management practices. When bulk sewage sludge is non-EQ
for pollutants, the land applier also must keep records tracking the cumulative pollutant loadings.
The land applier must also keep records describing the procedures used and the results of the
investigations of previous applications of sewage sludge subject to CPLRs. When the site has
reached 90 percent of its CPLR, the land applier should notify the preparer annually until the
site has reached 100 percent. At that point, no additional sewage sludge that is non-EQ for
pollutants can be applied. When bulk sewage sludge is non-EQ for pathogens, the land applier
must keep records on the implementation of Class B site restrictions. When bulk sewage sludge
is non-EQ for vector attraction reduction, the land applier must keep records documenting
implementation of one of the vector attraction reduction options (i.e., option 9 or 10).
In addition, the land applier must sign a certification as to whether he or she is in compliance
with site restrictions, vector attraction reduction options, and/or management practices whenever
28
-------
Section Two Requirements for Land Application
these requirements are applicable. Most records must be kept and made readily available to
inspectors for a period of 5 years. Where sewage sludge that is non-EQ for pollutants is being
applied, the land applier must maintain records documenting the cumulative pollutant loadings
for each application site indefinitely.
2.8 Reporting (40 CFR 503.18)
The reporting requirements under Part 503 apply to major municipal NPDES permittees and
Class I Sludge Management Facilities. Major municipal NPDES permittees are publicly owned
treatment works (POTWs) with a design flow rate equal to or greater than 1 million gallons per
day and POTWs with a service population of 10,000 people or more. Class I sludge
management facilities are usually POTWs that are required to have an approved pretreatment
program under 40 CFR 403.8(a), including any POTW located in a State that has elected to
assume local pretreatment program responsibilities under 40 CFR 403.10(e). In addition, the
EPA Regional Administrator may use his or her discretion to designate other treatment works
treating domestic sewage (TWTDS) as Class I sludge management facilities. Land appliers are
not TWTDS unless designated as such by the EPA Regional Administrator. In order to have
reporting requirements under Part 503, a land applier must be designated both a TWTDS and
a Class I sludge management facility.
If the land applier is designated as a Class I sludge management facility, the permitting authority
will probably issue a permit to the land applier that describes the reporting requirements.
Persons required to report must do so by February 19 of each year. Each report should cover
the previous calendar year (i.e., January 1 through December 31). Reports should be submitted
otherwise. The address for each Branch Chief is provided on the inside of the back cover of
this document.

Requirements for Land Application Section Two
facility. Any land applier who is also a preparer should consult the manual entitled Preparing
Sewage Sludge for Land Application or Surface Disposal-A Guide for Preparers of Sewage
Sludge on the Monitoring, Recordkeeping, and Reporting Requirements of the Federal Standards
for the Use or Disposal of Sewage Sludge, 40 503 (EPA, 1993), to determine the
information to include in the preparer's portion of the report.
Additional Reporting at Times Required of Land Appliers
Although it is unlikely that the land applier will have to report compliance information to the
permitting authority, the applier will need to report compliance information to the preparer of
the sewage sludge. Section 503.7 of the regulation states that the preparer is ultimately
responsible for making sure land application requirements are complied with, whether the
preparer performs the actual land application or not. Therefore, the preparer will need to
exercise some control over the activities of the applier and will need certain information to keep
records of those activities.
The transfer of land application information from the land applier to the preparer is not required
by Part 503. Therefore, to ensure the requisite flow of information, the exchange of this
information, and any other agreements, should be accomplished through a written agreement
between the two parties.
Liability
When a violation of land application requirements has occurred, the permitting authority, at its
discretion, may take an enforcement action against either or both parties, depending on the
nature and circumstances surrounding the violation.

Section Three Scenarios and Responsibilities
3. SEWAGE SLUDGE SCENARIOS AND LAND
APPLIER RESPONSIBILITIES
Nine scenarios have been given in Section 3 to help land appliers determine their responsibilities
under 40 CFR Part 503.
Each scenario represents a different combination of sewage sludge quality and methods of
distribution. In addition, each scenario includes a comprehensive list of all appropriate
requirements. The attempt has been made to provide scenarios that match many of the actual
land application situations that normally occur and provide guidance to the land applier on his
or her responsibilities.
Each scenario is presented in a separate section, which includes a brief description followed by
a list of the Part 503 requirements for the sewage sludge preparer and a list for the land applier.
The preparer's requirements are given so that the land applier will know what information to
expect and/or request from the preparer. The scenarios are presented according to the number
of applicable requirements, from the fewest to the greatest. Specific requirements that are
subject to Part 503 recordkeeping requirements are identified with an asterisk. The section
numbers of the applicable recordkeeping requirements are also given. Exhibit 7 provides a
matrix to help the land applier identify his or her scenario. The exhibit also gives the section
and page number for the discussion of each scenario.
3.1 Scenario 1-Land Application of Exceptional Quality Sewage Sludge
(either bulk sewage sludge or sewage sludge sold or given away in a
bag or other container)
EQ sewage sludge is considered to be comparable to other common fertilizer products. EQ
sewage sludge can be distributed and applied in bulk or sold or given away in a bag or other
container for application to agricultural land, forest, public contact sites, reclamation sites,
lawns, and home gardens. EQ sewage sludge can be applied to sites where the potential for
contact with the public is high, such as on urban parkland or golf courses, without any
restrictions. It can even be applied to sites where sewage sludge that is non-EQ for pollutants

"To determine your scenario using this matrix, locate the appropriate method of distribution and the parameter(s) that make the sludge non-EQ.
For example, if you are applying bagged sewage sludge that is EQ for all parameters, the appropriate scenario is Scenario 1, which is discussed
in Section 3.1. If you are applying bulk sewage sludge that is non-EQ for both pollutant levels and vectors, the appropriate scenario is Scenario
7, which is discussed in Section 3.7.
has been applied (even if the site has reached its maximum cumulative pollutant loading rate
[CPLR]) without having to document compliance with any management practices. EQ sewage
sludge can be transported to and applied in States other than where it was prepared without any
notification requirements.
Sewage sludge that is classified as EQ meets the following sewage sludge quality criteria:
Pollutants-Bom ceiling concentration limits (Table 1 of 40 CFR 503.13) and pollutant
concentration limits (Table 3 of 40 CFR 503.13) (see Exhibit 4 of this document).
Pathogens-One of the Class A pathogen reduction alternatives, (performed by the
preparer).
Attractiveness to Vectors-One of the sewage sludge vector attraction reduction
options 1 through 8, (performed by the preparer).
32
-------
Section Two Scenarios and Responsibilities
Requirements for the Preparer Under Scenario 1
The preparer is required to document the attainment of EQ sewage sludge quality and maintain
these data in his or her records. The preparer is not required to provide the land applier with
this documentation, and the land applier is not required to request it. Even though the general
requirement for notice and necessary information does not apply to EQ sewage sludge, the
preparer should be willing to provide documentation to ensure the land applier that the sewage
sludge meets EQ criteria. Data on sewage sludge quality are not confidential.
Requirements for the Land Applier Under Scenario 1
The land applier has no requirements when applying EQ sewage sludge as long as the land
applier does not mix it with non-EQ sewage sludge before application. If the land applier
further processes EQ sewage sludge by mixing it with other sewage sludge that is non-EQ, he
or she meets the Part 503 definition of a preparer by virtue of the fact that non-EQ sludge is a
part of the mixture. The individual is then responsible for monitoring and documenting sewage
sludge quality.
3.2 Scenario 2-Land Application of Sewage Sludge That Is Non-EQ Due
to Pollutant Levels and Is Sold or Given Away in a Bag or Other
Container (i.e., subject to annual pollutant loading rates)
Scenario 2 addresses sewage sludge that is non-EQ due to pollutant levels (sewage sludge that
meets the ceiling concentration limits but not the pollutant concentration limits) and is sold or
given away in a bag or other container (i.e., 1 metric ton or less). Sewage sludge in this
scenario meets the following criteria:
Pollutants-Ceiling concentration limits (Table 1 of 40 CFR 503.13) and annual
pollutant loading rates (APLRs), (Table 4 of 40 CFR 503.13) (see Exhibit 4 of this
document).
Pathogens-One of the Class A pathogen reduction alternatives, (performed by the
preparer).
Attractiveness to Vectors-One of the vector attraction reduction options 1 through
8, (performed by the preparer).
33
-------
Scenarios and Responsibilities Section Three
Sewage sludge sold or given away in bags or other containers is frequently used by homeowners
for gardens or lawns. Because the potential for human contact with this material is high, sewage
sludge that is non-EQ for pollutants is the only type of non-EQ sewage sludge that may be sold
or given away in a bag or other container. Sewage sludge or material derived from sewage
sludge must always meet the EQ pathogen and vector attraction reduction requirements to be
sold or given away in a bag or other container. Sewage sludge that is non-EQ due to pathogens
and/or vector attraction reduction must be land applied in bulk.
Requirements for the Preparer Under Scenario 2
The preparer of sewage sludge that is non-EQ for pollutants and is sold or given away in a bag
or other container for application to the land is required to:
1. Document compliance with ceiling concentration limits
2. Document compliance with Class A pathogen reduction requirements
3. Document compliance with one of the sewage sludge vector attraction reduction
options 1 through 8.
4. Certify compliance status with pathogen and vector attraction reduction.
5. Determine the appropriate annual whole sludge application rate (using the procedure
in Appendix A of Part 503) based on the pollutant content of the sewage sludge.
6. Provide the information to the land applier (e.g., homeowner) by either affixing a
label to the bag or other container or providing an information sheet when the
material is sold or given away.
Requirements for the Land Applier Under Scenario 2
The land applier of sewage sludge that is non-EQ for pollutants and sold or given away in a bag
or other container is required to read and follow the instructions given on the label or
information sheet.

preparer).
Attractiveness to Vectors-One of the vector attraction reduction options 1 through
8, (performed by the preparer).

Record Keeping Requirements Section Four
4. RECORDKEEPING REQUIREMENTS
Section 4 provides the land applier with additional guidance on the recordkeeping requirements
in 40 Code of Federal Regulations (CFR) Part 503. In particular, this section gives suggestions
on the type of information that may assist the land applier in documenting compliance with the
following requirements:
• Cumulative pollutant loading rates (CPLRs)
• Class B site restrictions
• Vector attraction reduction option 9 or 10
• Management practices.
4.1 Records of Cumulative Pollutant Loading Rates (Scenarios 3, 6, 7,
and 9)
Any time bulk sewage sludge that is non-EQ for pollutants is land applied, the land applier must
keep records. Bulk sewage sludge that is land applied and subject to the CPLRs has extensive
recordkeeping requirements relative to pollutants. The land applier must track the cumulative
amount of pollutants in bulk sewage sludge applied to the site and must keep records that
demonstrate compliance with CPLR limits. Appendix B contains worksheets to help track
CPLRs.
The land applier must keep the following records indefinitely:
• The location of each site (exact street address or latitude and longitude for the
geographic center) on which the bulk sewage sludge is applied
• The number of hectares in each site
• The date and time that the sewage sludge is applied to each site
• The amount of sewage sludge (in dry metric tons) that is applied to each site
56
-------
Section Four Record Keeping Requirements
• The cumulative amount of each pollutant in the sewage sludge (in kilograms per
hectare) applied to each site, including any amounts of pollutants from the previous
application of sewage sludge.
• A signed certification statement (see Appendix F) that the land applier has performed
the required inquiries in 503.12 (e)(2) prior to the application of bulk sewage sludge
that is non-EQ for pollutants to determine whether any sewage sludge of this quality
has been previously applied to the site
• Notice to permitting authority providing location of land application site and name,
address, telephone number, and NPDES permit number (if appropriate) of the land
applier
• A description of how the requirements to obtain information in 503.12 (e)(2) were or
were not met, including correspondence between the permitting authority and other
land appliers regarding previous applications of sewage sludge.
These records should include correspondence between the land applier and permitting authority
identifying the land applier and location of the site and inquiring about past applications of
sewage sludge subject to CPLRs. Records should also contain correspondence between the land
applier and any other land appliers who used the site after July 20, 1993, for application of
sewage sludge subject to CPLRs. Correspondence must include documentation of the cumulative
pollutant loadings from previous applications of bulk sewage sludge that was non-EQ for
pollutants.
4.2 Records of Class B Site Restrictions (Scenarios 4, 6, 8, and 9)
Any time bulk sewage sludge that is non-EQ for pathogens is land applied, the land applier must
keep records. Because Class B sewage sludge usually has higher levels of pathogens than Class
A sewage sludge, site restrictions are used to prevent public exposure and to control crop
harvesting and grazing. To fulfill recordkeeping requirements for site restrictions, the land
applier, at a minimum, should provide the landowner/leaseholder with a notification statement
identifying all applicable site restrictions and certify that the notification was given. A
notification similar to the example in Appendix A can be used to inform the landowner of the
applicable site restrictions. If the land applier implements the site restrictions, then he or she
57
-------
Record Keeping Requirements Section Four
should keep records describing the site restrictions used. The Part 503 regulation requires these
records to be kept for 5 years.
As described in Section 2, there are two categories of Class B site restrictions: (1) public access
restriction and (2) crop harvest and animal grazing. All sites are subject to public access
restriction. If the land applier is implementing site restrictions to control public access for Class
B sewage sludge, he or she must keep the following records for 5 years:
A description of site uses (e.g., cultivation of feed crops, growing turf, grazing
animals, public park, or private forest)
A description of the particular procedure(s) used to restrict public access to the site
(e.g., fences if the potential for public contact is high, signs indicating the duration
of the site restrictions)
Certification that the land applier informed the landowner of the appropriate site
restrictions or complied with the site restrictions.
If the land applier is implementing site restrictions for crop harvesting and animal grazing for
Class B sewage sludge, he or she must keep the following records for 5 years:
• A description of activities performed at the site (e.g., cultivating feed crops, growing
turf, grazing animals)
• Dates of land application, incorporation into the soil (if appropriate), and harvesting
or grazing
• Certification that the land applier has informed the landowner of the appropriate site
restrictions or complied with the site restrictions.
4.3 Records of Vector Attraction Reduction Option 9 or 10 (Scenarios 5,
7, 8, and 9)
The land application of sewage sludge that is non-EQ for vector attraction reduction requires the
land applier to develop additional records. Whenever vector attraction reduction option 9 or 10
is used, the land applier must document the method for meeting this requirement, in addition to
completing a certification of compliance status. These records must be kept for 5 years. One
58
-------
Section Four Record Keeping Requirements
method to fulfill this responsibility is to use a bound field notebook to record visual observations
and other information to document compliance each time the sewage sludge is land applied. At
a minimum, the following information should be recorded:
• Location of the field on which bulk sewage sludge is applied (street address or latitude
and longitude of the center of the site)
• Date of application
• Pathogen reduction class
• Time elapsed between Class A pathogen reduction and sewage sludge incorporation
or injection
• Whether visible amounts of sewage sludge are present on land surface after 1 hour of
injection.
In addition, the land applier must certify whether the vector attraction reduction requirements
have been met. Appendix F provides an example certification statement.
4.4 Records of Management Practices (Scenarios 3 through 9)
The land applier of bulk sewage sludge that is non-EQ for either one, two, or all three
parameters (i.e., pollutants, pathogens, vectors) must maintain records that include a description
of how the management practices were met at the site. The land applier must develop and keep
records for each land application site for 5 years. In addition, the land applier must certify each
time bulk sewage sludge is land applied whether or not management practices have been met
(see Appendix F). The following sections briefly describe the types of documentation that
should be recorded to demonstrate compliance with the four management practices that apply
to land application of bulk sewage sludge.
59
-------
Record Keeping Requirements Section Four
Threatened or Endangered Species
The land applier must keep the following documentation to demonstrate that the site has been
evaluated for potential effects on threatened or endangered species or their designated critical
habitats and that necessary protective measures were identified and implemented, if necessary:
A list of threatened or endangered species in the area or documentation from the Fish
and Wildlife Service (FWS) that none exist.
The land applier should retain all documentation to demonstrate that the site was
evaluated for potential effects to threatened or endangered species and/or their habitat,
and that necessary protective measures were identified and implemented. The
telephone number of the appropriate local FWS field office can be obtained from the
FWS regional offices, listed in Appendix D.
Flooded. Frozen, or Snow-Covered Land
To fulfill the recordkeeping requirements applicable to management practices for flooded,
frozen, or snow-covered land, the land applier must develop and keep information to show that
(1) the sewage sludge was not applied to the land when the land was flooded, frozen, or covered
with snow, (2) the sewage sludge applied under these conditions did not enter any waters of the
United States, or (3) protection of nearby wetlands or other waters of the United States was
already appropriately covered by a permit. The types of records that could be used to document
this information include:
• Records obtained prior to use of the site that are updated periodically
- A copy of any permit issued pursuant to either Section 402 or 404 of the Clean
Water Act
- The average uninterrupted slope of the land application site and the distance of
nearby waters of the United States from the boundary of the application site
- A description of the runoff controls used at the site to prevent any sewage sludge
from entering waters of the United States
- Floodplain information for the application site (e.g., Soil Conservation Service soil
survey information, flood insurance floodplain maps, or local records on the period
or extent of flooding events) and a description of how land application of sewage
sludge is managed to avoid surface water contamination during periods of flooding.
60
-------
Section Four Record Keeping Requirements
• Field notebook entries recorded each time sewage sludge is applied to the site
- The location and size of the land application site
- The date of each application and time, if applicable
- The application method used (surface spreading, incorporation, injection)
- The amount of bulk sewage sludge applied to the site and its percent solids content
- The existing crop or crop to be grown (e.g., soy beans in June through August,
sorghum in August through October)
- A general description of the weather and soil conditions preceding and during each
application (e.g., soil is dry; rain is not forecasted in the next 5 to 7 days)
Distance to Waters of the United States
To document the existence of the lo-meter setback distance from waters of the United States to
prevent sewage sludge from entering waters of the United States, the land applier must maintain
appropriate records, including the following:
• Records obtained prior to use of the site that are updated periodically
- A site map indicating the location of waters of the United States and the buffer
zone or a field book entry for each application site describing its size, location,
slope, distance between the boundary of the land application site and nearest waters
of the United States; the approximate length of each water body frontage; the
width, length, and slope of the protective buffer zone provided for that water body;
and a description of the vegetative cover, if any, of the buffer zone
- A description of how the buffer zone is marked in the field (e.g., flags, fences,
vegetation)
- A copy of advance approval from the permitting authority allowing a buffer zone
that is less than 10 meters
- An overall management plan describing runoff controls for the land application
site, including buffer zones and tillage practices
- If an overall management plan is not available, a field book entry for each
application site describing any other runoff controls used at the site to minimize or
prevent the sewage sludge from being washed off into adjacent waters of the
United States.
• Field notebook entries recorded each time bulk sewage sludge is applied to the site
- Each time bulk sewage sludge is applied to a site with a buffer zone, a field book
entry documenting the condition of the buffer zone, including its width and any
vegetative cover. Part 503 does not require buffer strips to be vegetated; however,
this is strongly recommended.
61
-------
Record Keeping Requirements Section Four
Agronomic Rate
To demonstrate compliance with requirements for the agronomic rate, the land applier should
keep the following documentation on file:
The type of crop or vegetation to be grown on the land and the annual nitrogen
requirement for the crop or vegetation or the annual whole sewage sludge application
rate recommended by the Cooperative Extension Service
The amount of supplemental fertilizer to be applied to the land and the nitrogen
content of the fertilizer (optional)
The original calculations used to design the agronomic rate, including all assumptions
and sources of background information, and data for the variables used in the
calculation
- Amount of nitrogen required by the crop or vegetation (available from the County
Cooperative Extension Service Agent, Land Grant University and U.S. Department
of Agriculture)
- Values for the nitrogen content of the sewage sludge, usually determined from an
analysis of sewage sludge for nitrate-nitrogen, ammonium-nitrogen, and total
Kjeldahl nitrogen
- Values for nitrogen content of supplemental fertilizers, if applicable/known
(optional)
- Results of soil sampling for residual nitrogen or estimates of nitrogen available
from crop residue and previous applications of sewage sludge or manure, if
applicable. Also estimates of available nitrogen from previous applications of

GUIDANCE FOR OPTIONAL SEWAGE SLUDGE QUALITY MONITORING

Appendices
Monitoring
The preparer is required to monitor sewage sludge quality to ensure compliance with the Part
503 requirements. The land applier may want to periodically verify the sewage sludge quality
as well. This section is designed to instruct land appliers on how to verify whether the sewage
sludge they are land applying meets the requirements for Part 503. The following materials
contain detailed guidance on the collection and analysis of sewage sludge samples:
POTW Sewage Sludge Sampling and Analysis Guidance Document (EPA, 1989, and
updates).

1992)

Attraction in Sewage Sludge (EPA, 1992)
Sewage Sludge Sampling Techniques (demonstration video) (EPA, 1993).
Regulated Parameters (what to monitor)
The land applier may want to periodically monitor the parameters that Part 503 requires
preparers to monitor. Regulated parameters include inorganic pollutants (i.e., metals), pathogens
or non-pathogenic indicator organisms, and vector attraction reduction characteristics.
Specifically, all sewage sludge that is land applied must be monitored for nitrogen and the
following 10 metals: arsenic, cadmium, chromium, copper, lead, mercury, molybdenum,
nickel, selenium, and zinc. In addition to the metals, preparers are required to monitor bulk
sewage sludge for nitrogen, pathogens (or organisms that would indicate the presence of
pathogens), and vector attraction characteristics when called for by the pathogen reduction
alternative or vector attraction reduction option. The specific pathogen and vector attraction
reduction parameters vary depending on which methods of reduction for each are are used.
C-l
-------
Appendices
Indicator Organism—An indicator organism (e.g., fecal conform) is a non-pathogenic
organism whose presence implies the presence of pathogenic organisms. Indicator
organisms are selected to be conservative estimates of the potential for pathogenicity.
Vector Attraction—Characteristics (e.g., odor) that attract birds, Insects, and other
animals that are capable of transmitting infectious agents.
Laboratory results for sewage sludge are typically reported in one of two forms-wet weight
(i.e., mg/L) or dry weight (i.e., mg/kg). The concentration limits for pollutants and pathogens
in the regulation are expressed as dry weight concentrations. Therefore, if laboratory results
are reported as wet weight, the percent solids content of the sewage sludge must be determined
to verify compliance with sewage sludge requirements. The percent solids value is used to
convert analytical results expressed as a wet weight basis to a dry weight basis, as demonstrated
in Exhibit C-l.
Exhibit C-l. Expressing Wet Weight Pollutant Concentrations on Dry Weight Basis
If you assume that the specific gravity of the solids is equivalent to the specific gravity of water,
a simplified equation can be used to express the concentration of a pollutant on a dry weight basis:
Solids =
L kg
where: A is the concentration of the pollutant in the sewage sludge on a wet basis in mg/L
B is the concentration of the pollutant in the sewage sludge on a dry weight basis, in
mg/kg.
For example, if the concentration of zinc in the sewage sludge is reported as 200 mg/L and the
percent solids content of the sewage sludge is 24%, the concentration can be converted to a dry
weight basis using the equation given above:
200 + 0.24 = 833
L kg.

Appendices
Procedures for Sampling and Analysis (how to monitor)
This section describes three factors critical for the development and implementation of a sewage
sludge quality monitoring program that will produce precise and reliable analytical results and
allow the land applier to verify the accuracy with which the preparer has determined sewage
sludge quality:
• Collection of representative samples of the sewage sludge
• Use of appropriate analytical techniques
• Adherence to quality assurance/quality control (QA/QC) procedures for sampling and
analysis.
Representative Samples
To obtain a representative sample of sewage sludge, the sample must be taken from the correct
locations, represent the entire amount of sewage sludge, and be handled properly from the time
of collection through analysis. Sewage sludge sampling techniques are described in the
following references, which are available through the EPA Regional Sewage Sludge Coordinator
or the EPA Office of Water Resource Center:
POTW Sewage Sludge Sampling and Analysis Guidance Document (EPA, 1989, and
updates)
Environmental Regulations and Technology: Control of Pathogens and Vectors in
Sewage Sludge (EPA, 1992)
Sewage Sludge Sampling Techniques (demonstration video) (EPA, 1993).
Appropriate sample containers must be used. For some parameters, such as volatile organics,
glass containers are essential. Either plastic or glass containers can be used to collect samples
for analysis of metals, indicator organisms, and pathogens. The containers must be acid cleaned
and contaminant free. Sterile containers must be used for indicator organisms and pathogens.
C-3
-------
Appendices
In addition, sufficient sample volumes must be collected to perform the analyses. The sample
volumes needed for each analysis vary depending on the percent total solids of the sewage sludge
and the detection level of the analytical method used. Check with your laboratory to make sure
you collect more than enough sewage sludge for analysis. A conservative rule of thumb is to
collect 1 L or a volume containing 1 gram dry weight for metals analysis and 1 L for pathogens
and indicator organisms.
Appropriate preservation techniques ensure that samples remain representative during the holding
time prior to analysis. At a minimum, all sewage sludge samples should be preserved by
cooling to 4°C with dry ice or an ice water bath. The holding time also influences the validity
of analytical results. It is important to know and respect sample holding times for each
parameter being analyzed. With the exception of mercury, the metals do not degrade easily and
can be held up to 6 months. Mercury can be held for 13 days in a plastic container and 28 days
in a glass container. Fecal coliform and salmonella have a very short holding time; if the
samples cannot be delivered to the lab within 1 hour, they should be chilled promptly (using an
ice and water bath) to 4°C and delivered to the lab within 24 hours. Samples for viable
helminth ova can be held for up to 1 month if chilled to 4°C. Samples for viruses can be frozen
for up to 2 weeks.
Appropriate Analytical Techniques
To ensure that sewage sludge quality data are good, the land applier must use the analytical
methods specified in Part 503. Methods for analyzing inorganic pollutants are described in the
EPA document entitled, Test Methods for Evaluating Solid Waste (EPA, 1986). Exhibit C-2 lists
the methods for the analysis of metals. The following documents contain methods for pathogen
analysis; specific oxygen uptake rate; and total, fixed, and volatile solids:

Quality Assurance/Quality Control Procedures
The land applier may want to establish a QA program to ensure quality in sample collection,
laboratory analysis, and data validation. QA programs should address the following major areas:
Proper sample collection procedures, equipment, preservation methods, and chain-of-
custody procedures to ensure representative samples
Proper sample preparation procedures, instruments, equipment, and methodologies used
for the analyses of samples
Proper procedures and schedules for the calibration and maintenance of equipment and
instruments associated with the collection and analyses of samples.
QC, which is part of the QA program, relates to the routine use of established procedures and
policies during sample collection and analysis. The objective of QC procedures is to ultimately
control both the accuracy and the precision of all analytical measurements made. QC for sample
collection includes the use of duplicate and spiked samples, as well as sample blanks. QC for
sample analysis includes the use of spiked and split samples, proper calibration protocols, and
appropriate analytical methods, detection limits, and procedures. Guidance on QA/QC for
sample collection and analysis is contained in Chapter 1 of Test Methods for Analysis of Solid
Wastes (EPA, 1986). Each analytical method describes additional QC procedures.

WORKSHEET FOR CALCULATING THE AGRONOMIC RATE
-------
Appendices
AGRONOMIC RATE FOR NITROGEN
Nitrogen exists in the soils and sewage sludge in three basic forms:
Organic (C-NH2)-Carbon-based compounds such as proteins and amino acids. This
form is not available to plants and must be converted to inorganic nitrogen by soil
microorganisms. Mineralization is the conversion of organic N to inorganic N in the
form of ammonium. Mineralization rates vary for different types of sewage sludge,
but most of the organic nitrogen is mineralized to inorganic N in the first year. The
rate of mineralization is assumed to be low at the end of the third year after
application. Thus, after the third year, the amount mineralized is not considered in the
calculation of the agronomic rate. See examples on page E-8.
Inorganic (ammonium NH4+, nitrite N02, nitrate NO3")-Plants use the nitrate and
ammonium ions. The soil microbes and plants compete for this inorganic N. Rapidly
growing soil microbes can immobilize or "tie up" the ammonium and nitrate in the soil
by converting it to the organic form, and may temporarily deplete the available N in
the soil for plant uptake. The positively charged ammonium ions are adsorbed by clay
and organic matter so that little of this form is leached. Nitrification is the process
whereby soil microbes convert ammonium to nitrate. Nitrate is very mobile and
readily leached. Nitrite is usually not present in significant concentrations.
Gases (nitrogen, N2, ammonia NH3)-Nitrogen gas is present in the soil atmosphere
(air) and a source of nitrogen for legumes that can convert this to ammonium (NH4+),
which is then used by the plant. In anaerobic conditions, microorganisms can convert
nitrate to nitrogen gas and nitrous oxide (N2O); this process is called denitrification.
Under alkaline conditions, ammonium ions lose a hydrogen ion and become ammonia,
which readily volatilizes (producing ammonia gas NH3 ).
Plants can use only a portion of the total nitrogen in the sewage sludge. Some of the nitrate and
ammonium is lost to the atmosphere by denitrification and volatilization, and some of the organic
nitrogen becomes available over time as the mineralization process converts the organic forms
to ammonium and nitrate. Some of the nitrate is lost through leaching. The goal when
designing the agronomic rate for an application site is to supply the necessary amount of nitrogen
needed for the crops or vegetation to produce the desired harvest yield with no leaching of the
nitrogen below the root zone. The rates of mineralization, plant uptake, volatilization, and
denitrification are dependent on many factors and will vary from site to site and at the same site.
E-l
-------
Appendices
Factors Affecting Nitrogen Availability
Predicting how much sewage sludge is needed to provide the nitrogen sufficient to meet crop
yield goals and minimize leaching of nitrogen below the root zone requires consideration of
numerous factors. The following are some factors that influence the amount of sewage sludge
that can be applied:
Total nitrogen content in sewage sludge and the concentrations (or percentage of the
total nitrogen) of the various nitrogen forms in the sewage sludge are influenced by the
types of processing operations. Anaerobic digestion (30 days or longer) produces
sludge with high levels of ammonium but little nitrate (oxygen is required to proceed
from ammonia to nitrate) and converts most of the readily available organic nitrogen
to ammonium nitrogen. Aerobically digested sewage sludge has higher levels of nitrate
than anaerobically digested sewage sludge. Dewatering reduces the levels of both
nitrate and ammonium nitrogen.
The mineralization rate at the application site is affected by how well the sewage
sludge was stabilized in the digester. Poor stabilization results in more organic
nitrogen for mineralization. Good stabilization converts most of the organic nitrogen
into readily available inorganic N, leaving only that which is relatively inert and
resistant to further mineralization (this sewage sludge may have a low mineralization
rate).
The mineralization rate is also influenced by soil temperature. Temperature affects the
metabolic rate of microorganisms, thus mineralization rates are typically higher in the
summer months than in the winter months.
The amount of ammonium lost through volatilization to the atmosphere is affected by
pH, application method, application rate, and soil moisture.
Soil/sewage sludge pH-Alkaline sewage sludges have greater volatilization losses
than more acidic sewage sludge. The high concentration of hydrogen ions in an
acid sewage sludge increases the level of ammonium ions in the liquid phase of the
sewage sludge and consequently diminishes losses of ammonia.
Application method-The more thoroughly sewage sludge is mixed with soil after
application, the lower the volatilization loss. Increasing the interaction of the
ammonium ion with the cation exchange complex of the soil reduces the amount
subject to volatilization. Volatilization loss is minimal with subsurface injection
of sewage sludge. If sewage sludge is left on the soil surface, volatilization occurs
rapidly with the greatest loss occurring within the first week. Incorporation of
surface applied sewage sludge immediately after application can greatly reduce the
loss.
E-2
-------
Appendices
- Application rate-Greater amounts of sewage sludge applied increase the
percentage of ammonium ions lost by volatilization, possibly because of the
decrease in the number of ammonium ions in direct contact with the soil.
Soil moisture-If the soil is saturated before surface application of liquid sewage
sludge, the volatilization rate will be greater because of the decrease in the rate of
infiltration. Slowing or impeding infiltration increases the length of time the
aqueous ammonium ion solution is exposed to drying conditions on the soil
surface, thus increasing the volatilization losses from surface applied alkaline
sewage sludge.
The amount of nitrate (actual N gas) that is lost to the atmosphere by denitrification is
affected by factors that contribute to anaerobic conditions and by the metabolic rate of
the denitrifying microorganisms. The factors are the following:
Soil moisture-Saturated soils have fewer pore spaces occupied by oxygen, thus
creating anaerobic conditions that favor the growth of denitrifying microorganisms.
Soil type-The texture of soil, coarse (sandy) to fine (clay), affects porosity and
capacity to store water and oxygen, thus influencing the prevalence of anaerobic
conditions even when soil is not saturated.
Carbon source-An abundant source of readily oxidizable carbon will increase the
denitrification rate.
Nitrate levels-Denitrification will occur rapidly where nitrate levels provide a
sufficient source of nitrogen for the microorganisms.
Procedures for Designing the Agronomic Rate
The site-specific variability of the above factors means that designing the agronomic rate should
be done on a site-specific basis. Many State sewage sludge management programs have
developed procedures based on the knowledge and experience gained in regulating sewage sludge
land application. These procedures account for the local conditions that affect the agronomic
rate. If you are unfamiliar with the specific procedures to use in calculating the agronomic rate,
you should contact the State sewage sludge management authority. You can also obtain
assistance from the Cooperative Extension Service, the Soil Conservation Service, or
independent agronomists specializing in soil evaluation and nutrient management. These
agencies and individuals can provide information on crop nitrogen needs, soil nitrogen testing,
mineralization rates, and volatilization and denitrification losses.
This appendix provides a worksheet illustrating one approach for designing the agronomic rate.
This worksheet is an example and is not intended to replace the procedures currently being used
E-3
-------
Appendices
by regulatory authorities or agricultural extension services. Many of the factors included in this
example are common to most procedures for designing agronomic rate. Some of the less
common factors are noted as optional on the worksheet.
At a minimum, all of these procedures consider the nitrogen requirement of the crop, and the
nitrogen content of the sewage sludge. Most procedures address residual nitrogen either through
site-specific soil nitrogen data (from soil monitoring) or estimates of the amount of residual
nitrogen from previous sewage sludge applications. If appropriate, nitrogen losses and nitrogen
available from sources other than the sewage sludge can be factored into the procedure for
deriving the whole sludge application rate.
The nitrogen requirements for specific crops also differ by region and can be obtained from the
Cooperative Extension Service's fertilizer recommendations and guides available from the
County's Cooperative Extension Service Agent, Land Grant University, and U.S. Department
of Agriculture. Note that nitrogen fertilizer recommendations are not typically given for
legumes because they fix their own nitrogen. Example nitrogen requirements for selected crops
are provided in Exhibit E-l, but the land applier should get local information by contacting the
local extension agent. A list of the addresses and telephone numbers of local extension agents
can be obtained from a publication entitled County Agents, available from Century
Communications, Inc., 6201 Howard St., Niles, IL 60648, 708-647-1200.

WORKSHEET 2
EXAMPLE CALCULATION FOR AVAILABLE MINERALIZED ORGANIC
NITROGEN
The organic nitrogen in sewage sludge continues to decompose and release mineral nitrogen through the
mineralization process for several years following its initial application. This residual nitrogen from the previously
applied sewage sludge must be accounted for as part of the overall nutrient budget when determining the agronomic
rate for sewage sludge. Residual nitrogen can be determined through soil analysis or calculated using the following
procedure. These calculations must be done for each yearly sewage sludge application unless soil analysis is
performed prior to land application (see example calculations).
Instructions: Complete a separate table for each year sewage sludge was land applied. Note that most do not
calculate beyond the third year because the values become negligible. Sum the values of mineralized Org-N
(Column d) from each table for the particular calendar year you're trying to determine Org-N available. (See
example below .)

applied)

Rentainiag* {kg/ha}
Begin with year sewage sludge is applied, and continue for 2 more years.
2In the first year, this equals the amount of Org-N initially applied. In subsequent years, it represents the amount of
org-N remaining from the previous year (i.e., column e).
3The org-N content of the initially applied sewage sludge continues to be mineralized, at decreasing rates, for years
after initial application. See Exhibit E-3 for mineralization values.
Multiply column b and column c.
'Subtract column d from column b.
Example
Assume that anaerobically digested sewage sludge with a 3% org-N content (dry weight basis) was applied to the site
at a rate of 5 mt/ha in 1986. The following year, 1987, 3 mt/ha of sewage sludge (same org-N content as in 1986)
was applied to the same site. It is now 1988, and you want to calculate the available nitrogen from previous sewage
sludge applications.
In 1986, the org-N in the sewage sludge applied = (0.03) (5 mt/ha) (1,000 kg/mt) = 150 kg/ha.
In 1987, the org-N in the sewage sludge applied = (0.03) (3 mt/ha) (1,000 kg/mt = 90 kg/ha.
Calculate the available nitrogen from 1986 and 1987 in the following manner (assume anaerobically digested sewage
sludge).

To determine the total mineral&d organic nitrogen available in 1988 from the sewage sludge applied in 1986 and 1987,
add the mineralized Org-N value in the 1988 row of column d of the table for the 1986 sewage sludge to the mineralized
Org-N value in the 1988 row of column d of the table for the 1987 sewage sludge (i.e., 5.40 + 7.2 = 12.6 kg/ha).
Total mineralized Org-N available in 1988 from previous sewage sludge 12.6 kg/ha.
