OVERVIEW
  The U.S. Environmental Protection
  Agency (EPA) will continue to pro-
  mote municipal sewage sludge man-
  agement practices that provide for the
  beneficial use of sewage sludge while
  maintaining or improving environ-
  mental quality and protecting human
  health.

  Thousands of municipalities are
  currently land applying or otherwise
  recycling their sewage sludge. Both
  agricultural and non-agriculturial sites
  benefit from the use of sewage sludge,
  which typically contains $50 to $60 of
  nutrient and soil conditioning value
  per ton. Sewage sludge has been
  successfully used in the production of
  many different food, feed, and horti-
  cultural crops, in sod production and
  turf maintenance, in the management
  of forest production, as well as in
  reclaiming and revegetating areas dis-
  turbed by mining,  construction, and
  waste disposal activities.

  Sludges should be adequately stabil-
  ized prior to use on land. This  can
  be accomplished by digestion,
  chemical stabilization, or other means.
  A potential benefit from anaerobic
  digestion is the recovery of methane
gas from the digestion process which
can be used as a fuel source.

EPA proposed new technical standards
to govern the use and disposal of
sewage sludge on February 6, 1989,
and is seeking public comment and
data for their improvement.  Comments
must be received by August 7, 1989.

These proposed standards may change
based upon the Agency's data gather-
ing initiatives and the comments
received. Therefore, EPA advises
permit writing authorities and others
not to rely on the proposed standards as
a basis for evaluating the safety of
proposed sludge management projects
or establishing appropriate require-
ments for sludge use and disposal. EPA
intends to carefully weigh the extent to
which the proposed standards should
be used, and appropriate advice will
be given in the revised "Guidance for
Writing Case-By-Case Permit
Requirements for Municipal Sewage
Sludge" scheduled for later this year.

The proposed technical standards can
be used to gain an understanding of
the types of practices and kinds of
pollutants that may be regulated when
the revised standards are promulgated.
                                 1

-------
Purpose

The U.S. Environmental Protection
Agency published the "Proposed
Standards for the Disposal of Sewage
Sludge" in the Federal Register (Volume
54, No. 23, pp. 5746-5902) for public
comment on February 6, 1989. This
brochure helps clarify the purpose of the
new proposed sewage sludge standards
and reaffirms the Agency's policy of
encouraging beneficial use of sewage
sludge. This publication also describes
current Federal and State requirements
that will govern sludge use and disposal
practices until the new technical sludge
regulations are promulgated in final
form.
 EPA Policy on Beneficial Use
 of Municipal Sludge

 EPA's official "Policy on Municipal
 Sludge Management" (49 FR 24358,
 June  12, 1984) states that:

 "The U.S. Environmental Protection
 Agency (EPA) will actively promote
 those municipal sludge management
 practices that provide for the beneficial
 use of sludge while maintaining or
 improving environmental quality and
 protecting public health. To implement
 this policy, EPA will continue to issue
 regulations that protect public health
 and other environmental values... Local
 communities will remain responsible for
 choosing among alternative programs;
for planning, constructing, and operat-
 ing facilities to meet their needs; and for
 ensuring the continuing availability of
 adequate and acceptable disposal or use
 capacity."

-------
 As noted in the policy statement, EPA
 prefers well-managed beneficial uses of
 sewage sludge. Such uses include land
 application practices utilizing sludge as a
 soil amendment or fertilizer supplement
 and various practices that derive energy
 from sludge or convert it to useful
 products. Such practices can help reduce
 the volume of waste to be disposed of,
 thus reducing the rate at which the
 limited remaining capacity in landfills is
used. These practices also avoid potential
pollution problems from disposal prac-
tices such as landfilling, incineration,
ocean dumping, and discharge to coastal
waters. Other benefits of sludge use
include reduced need for inorganic fer-
tilizers, improved soil fertility and tilth
for better plant growth, decreased con-
sumpion of energy, and reduced hazard-
ous air emissions.

-------
Agricultural Use of Sludge

EPA's policy of promoting the beneficial
use of municipal sewage sludge is based
upon years of study and experience.
Hundreds of studies have been con-
ducted, and several thousand POTWs
are recycling their sludge for use on
land in the United States. In Ohio and
Maryland, for example, over 55% and
85%. respectively, of all sludge produced
in each state is used on land.

Examples of communities recycling their
sludge include Hannibal. MO (population
19.000). Madison. WI (population
250.000). and Seattle. WA (population
1.1 million). Each of these municipalities
were 1988 winners in the EPA National
Awards Program for excellence in using

-------
and promoting the beneficial use of
sludge. Hannibal recovers 100% of the
costs of hauling and spreading sludge
from its sales to farmers, and Madison
receives $12 per acre from farmers for
applying the sludge. Madison currently
treats 3,000 to 4,000 acres of farmland
with sludge each year and has a waiting
list totalling 22,000 acres of farmland.
Seattle treats forest as well as agricultural
land.

Each dry ton of sludge contains  about $50
to $60 worth of valuable nitrogen,
phosphorus, trace nutrients, and organic
matter. During 1988, all sludge from met-
ropolitan Washington, D.C. (population 3
million) was used on land. Over one-third
(37,000 dry tons) was applied to 7,000
acres of agricultural land in Virginia, and
about 30,000 dry tons was applied to
Maryland soils. The sludge was spread
at no charge to the farmers by private
contractors, providing the farmers with
several million dollars of benefit from the
soil nutrients and conditioners present in
the sludge. The balance of the Washing-
ton, D.C. area sludge was composted prior
to use.
This corn crop benefited from the use of sludge as a fertilizer.

-------
Non-Agricultural
Use of Sludge

The beneficial uses of
sludge extend beyond
agriculture. Sludge is used
in silviculture to increase
forest productivity and to
revegetate and stabilize
forest lands that have been
harvested or devastated by
fires, land slides, or other
natural disasters.

The application of sewage
sludge to forest land
shortens wood production
cycles by accelerating tree
growth, especially on
marginally productive
soils. Studies at the
University of Washington
on the use of sludge as a
fertilizer in silviculture
show height  and diameter
increases from two- to ten-
fold in various tree species
compared with control
groups grown without
sludge fertilizer.

University of Washington
research has  also shown
that trees grow twice as
fast on sludge-amended
soil. This means that a tree
which would typically be
cut after 60 years could be
cut after only 30 years to
supply lumber for a variety
of purposes.

            this growth period

Sludge is also used to stabilize and re-
vegetate areas destroyed by mining,
dredging, and construction activities. Air-
dried and composted sludge is frequently
used to fertilize highway median strips
and clover leaf exchanges, and for
covering expired landfills. Historically,
land reclamation by use of sludge has
been very successful and comparable in
cost to other methods. In a strip-mined
area in Fulton County, Illinois, reclam-
ation using municipal sewage sludge cost
$3,660 an acre, as compared with a range
of $3,395 to $6,290 an acre using other
methods.

Pennsylvania has used sludge generated
by Philadelphia to reclaim over 3,000
acres of devastated lands. Sludge has
been used in combination with fly ash to
revegetate soils that had become highly
contaminated over the past 90 years from

EPA's 1988 National Beneficial Sewage
Sludge Use Awards Program.


Other Public Uses for Sludge

Sales to the public of sludge products for
many kinds of garden, nursery,
household and lawn uses continue to
increase. Milwaukee has been selling a
heat-dried product called Milorganite* to
the public throughout the United
States since the 1920s. Kellogg's Supply
Company* (a private firm in California)
has been selling sludge composted in Los
Angeles County, called Nitrohumus,* in
California and Arizona for over 60 years.
More than 15 products containing
* Vendor and trade names are included for the benefit of the reader and do not imply an endorsement by EPA.

-------
Nitrohumus are being marketed. These
composted sludge products have been
used to establish playing field grass in
stadiums used by the Dodgers and the
Angels and as well as in the Rose Bowl.

Even the White House has used
composted sludge to completely
reestablish its lawns. During the last two
years, 825 tons of composted sludge
called Compro* were used in this highly
successful project. Similarly, the lawns at
Mount Vernon, the Washington
Monument grounds, and the Governor's
Mansion in Annapolis, Maryland were
renewed last year with Compro. The first
use of composted sludge on the
Washington, D.C. Mall (nearly 6,000
tons) was in 1976 to establish the
Constitution Gardens in time for the
United States Bicentennial Birthday
celebration.

Sludge should be stabilized before use.
Anaerobic digestion is used by many
wastewater treatment works for this
purpose. Methane gas is generated during
the anaerobic digestion process and has
considerable value as a fuel source. For
example, the 60MGD Tampa, Florida
 Picture on left shows sludge being applied next to a highway near Zion,
 Illinois. Photo on right shows the same area after sludge application.

-------
treatment works recovers about $500,000
worth of heat and electrical energy each
year from the methane produced by
anaerobicly digesting part of the 100 tons
of sludge solids it produces each day. As
a result of these energy savings, their
digestion facility is expected to
completely pay for itself in  seven and a
half years. Tampa reports that all of their
digested sludge is used on agricultural
land at an overall low cost of about $19
per dry ton. In the past, part of the their
sludge was also used for revegetating
gypsum spoils from phosphate mining.
Expert Opinions Regarding
Sludge Useability

In 1981, some Northwestern food
processors announced that they would no
longer accept fruits and vegetables for
processing that had been grown on
sludge-treated soils. Officials from the
U.S. Department of Agriculture (USDA),
the Food and Drug Administration
(FDA), and the EPA met with
representatives of the National Food
Processors Association to address the
food processors' concerns.
                                                                         11

-------
After careful analysis of the available
health and safety information pertaining
to these practices, the USDA, FDA, and
EPA issued guidance and a joint policy
statement in 1981 that was signed by the
Administrators of each Agency. The
Agencies endorsed the utilization of
sludge on land for the production of
fruits and vegetables and concluded:

"that the use of high quality sludges,
coupled with proper management
procedures, should safeguard the
consumer from contaminated crops,
minimize any potential adverse effect on
the environment," and "that, with the
adherence to the guidance contained in
[the Agencies' ] document, the safety
and wholesomeness of the fruit and
vegetable crops grown on sludge-
amended soils will be assured."

In 1983, over 200 health and
environmental experts from the United
States, Canada, and Europe met in
Denver, Colorado to assess the state of
the art for sewage sludge use and
disposal (10 years after a similar meeting
in Champaign, Illinois). This group of
experts arrived at a published consensus
that the existing guidance and regulations
were adequately protective of public
health and the environment, provided
that sewage sludge was used in

accordance with those provisions. They
concluded:

• "Guidelines have been developed to
  enable the environmentally safe use of
  sewage sludge containing median
  concentrations of metals and organics
  when the sludge is applied at agronom-
  ic rates based upon nitrogen or
  phosphorus utilization by crops."

• "Concentrations of synthetic organics in
  sludges are generally low, but high
  concentration may exist in some
  sludges. Most synthetic organics are
  decomposed in soil. Current Federal
  regulation for PCBs in sludges are
  adequate to protect human health."

• "Groundwater monitoring for nitrate-
  nitrogen is not needed where sludge
  nitrogen additions do not exceed
  fertilizer nitrogen recommendations for
  the crop grown."

• "Utilization of sludge for reclamation
  of disturbed land at rates higher than
  those for agricultural land, when
  properly implemented and managed,
  improves the quality of soils,
  groundwater, or vegetation."

• "With proper management and safety
  allowances based on research data,
  land application is a safe, beneficial
  and acceptable alternative for treatment
  of municipal wastewater and sludges."

• "In terms of current detection
  capability, Federal sludge disposal
  criteria are adequate to protect human
  health from pathogenic micro-
  organisms."

• "No longer are there  serious gaps in
  knowledge of the impact on human
  health of organic and inorganic con-
  taminants in municipal wastewater and
  sludge when applied to land."

From operational experiences and the
views of many Agency as well as  other
experts, it is apparent that the best-
management-practice-based guidance
and regulations, developed by EPA, have
been successfully guiding the beneficial
use of sludge.

Proposed Part 503 Sewage
Sludge Disposal  Standards

Pursuant to the statutory directive in
Section 405 of the Clean Water Act
(CWA), EPA expanded its regulatory
activities by proposing new risk-based
technical sludge regulations.  Once issued
in final form, these regulations will
appear at 40 CFR Part 503 and will
establish minimum Federal standards for
the use and disposal of sewage sludge
when applied to land, distributed and
marketed, placed in sludge-only landfills
(monofills) or on surface disposal sites,
or incinerated.

The co-landfilling of sludge with
municipal solid waste and ocean
dumping of sludge are covered under
other provisions and rulemaking (e.g.,
the new Part 258 Municipal Solid Waste
Landfill regulations as proposed [53  FR
33314] on August 30, 1988). Future
rulemaking under the  Section 405 CWA
authority will address additional sludge
pollutants and sewage sludge use and
disposal practices.

-------
The proposed rule contains standards for
each end use and disposal method
consisting of sludge concentration or
pollutant loading limits, management
practices, and other requirements such as
monitoring, record keeping, reporting,
and management controls over users and
contractors by treatment works.

As proposed, the requirements would
apply to both publicly owned treatment
works (POTWs) and privately owned
treatment works that treat domestic
waste water as well as septage. However,
sludges produced by privately owned
industrial facilities, which treat domestic
sewage along with industrial process
waste, will not be covered in the first
round of regulation.

Limitations of Proposed
Regulations

The proposed regulations raise many
scientific, technical, and policy issues not
addressed in prior Federal regulations.
Furthermore, the scope of the proposed
Part 503 standards has been constrained
by the adequacy of the information on
sewage sludge pollutants that formed the
basis of the proposal as well as the
sludge use and disposal practices
covered.

Therefore, the proposed pollutant limits
and management practices included in
the proposed regulations, and even the
basic approach to regulating sewage
sludge taken in the proposal, may change
 significantly based upon the Agency's
 data gathering and peer review efforts,
 and the public comments and information
 received in response to the proposal.

 Hence, permit writers and others
 involved in sludge management
 decisions should not use the proposed
 pollutant limits and management
 practices as a basis for evaluating the
 requirements for sludge management
 operations or the environmental safety of
 proposed sludge management projects.
 The Agency plans to carefully weigh the
 extent to which the proposal should be
 used, and appropriate advice will be
 given in the revised "Guidance for
 Writing Case-By-Case Permit
 Requirements for Municipal Sewage
 Sludge" scheduled for later this year.  It is
 appropriate, however, to note that the
 pollutants and practices in the proposed
 regulations will likely be addressed in
 some manner when the revised
 regulations are promulgated in final
 form.

 Study and Comment to Help
 Improve the Proposed
 Regulations

 To help remedy existing information
 gaps, the Agency is conducting a
 National Sewage Sludge Survey. The
purpose of the Survey is to obtain better
 information on current sewage sludge use
and disposal practices and detailed
analyses of sewage sludge pollutant
concentrations from a representative
14
                 J—a.

group of POTW
sludges. In addition,
EPA is gathering
data on environ-
mental mobility of
certain pollutants
(e.g., dioxins and
pathogens), refining
and expanding its
modeling capability
for specific pol-
lutants and disposal
methods, developing
supplemental infor-
mation on certain
disposal methods
including some not
addressed in the
proposal (e.g., municipal solid waste
incinerators co-firing sewage sludge),
and identifying the characteristics of
industrial sludges with a domestic
sewage component.

During the 180-day comment period,
experts from both inside and outside the
EPA are thoroughly reviewing the
technical basis of the proposal. The
review will involve representatives from
the Agency's Science Advisory Board,
environmental groups, academia, and
various scientific bodies with expertise in
areas covered by the proposed rule. With
the additional input and data obtained
during the technical and public reviews
of the proposal during the comment
period, the Agency should be able to
expand and refine the proposed
standards.

                  Applicable to Sewage Sludge
                  Use & Disposal Practices

                  Until the final Part 503 Sewage Sludge
                  Disposal Standards are issued, sewage
                  sludge use and disposal practices
                  continue to be governed by EPA, State,
                  and local requirements in current final
                  regulations that affect sludge
                  management practices (see Table 1).
                  Pursuant to Section 405(d) of the 1987
                  Water Quality Act amendments, the
                  Agency has established an "interim"
                  program for permitting POTW sludge
                  management practices on a case-by-case
                  basis by including conditions in NPDES
                  permits. This interim program is de-
                  scribed in a document entitled "Strategy
                  for Interim Implementation of Sludge
                  Requirements in Permits Issued to
                  POTWs" (see Notice of Availability for
                                                                         15

The Interim Strategy is designed
primarily for the period of time before
promulgation of the technical standards.
Through permits, it focuses on identify-
ing and addressing existing or potential
problems with sludge use or disposal
practices in the absence of promulgated
technical standards. The strategy states
that in developing permit limits for
POTWs in the interim, the primary
source of information for permit writers
should be the case-by-case guidance in
the draft document entitled "Guidance
for Writing Case-by-Case Permit
Requirements for Municipal Sewage
Sludge".

The draft guidance document is based on
existing Federal and State requirements
and guidance, and is currently being
revised. This guidance document and
future updates (a revised version should
be available by September 30, 1989) will
serve as the basis for EPA regulation of
sewage sludge until the Final Part 503
requirements are issued (currently
scheduled for promulgation by October
1991). (Note: The timing of
promulgation of the technical standards
is currently in litigation in Federal
district court. EPA informed the court
that it expected final promulgation in
October 1991 based upon projections
made in 1988; this date could change due
to court order or other changed
circumstances.)
This case-by-case approach will continue
until the Part 503 standards are issued in
final form and implemented through
EPA's new Part 501 State Sludge
Management Program Regulation and
Parts 122-124 NPDES permitting
requirements which were issued in final
form on May 2, 1989 in 54 FR 18716-
18796.

Following the final promulgation of the
Part 503 technical sludge regulations,
EPA's authority to impose sludge limits
in NPDES permits developed on a case-
by-case basis and issued to POTWs will
continue with respect to pollutants and
sludge management practices not
covered by the technical standards.

EPA is sensitive to the concerns that
problems may arise if interim permit
conditions are imposed that are
significantly different from those that
will be required by the final Part 503
technical regulations. Thus, the Agency's
interim  permitting strategy has sought to
adopt approaches that are consistent with
the anticipated direction of the technical
regulations. However, a primary
emphasis of the strategy is to ensure
compliance with existing Federal
requirements (see Table 1).

In general, additional limits will be
required only for "priority" POTWs with
known or suspected problems with
sludge use or disposal practices. This
includes most pretreatment POTWs and
POTWs that incinerate their sludge. For
the most part the limits  will be based on

                                   17

-------
existing Federal and State regulations
and guidance, often consisting of best
management practices rather than
numerical limits.

If the final Part 503 technical regulations
are less stringent than requirements
imposed during the interim period with
respect to concentration and loading
limits or management practices, the
interim period permit requirements can
be modified to the less stringent condi-
tions. This is because "anti-backsliding"
provisions of Section 402(o) of the CWA
will not apply to the Part 503 sewage
sludge use and disposal activities. It  is
important to note, however, that States
could choose not to reduce the stringency
of their permit requirements because
State requirements can by law be more,
but not less, stringent than Federal
requirements.

Request for Public Comment
on Proposed  Technical
Regulations

EPA encourages concerned parties to
review the proposed Part 503 technical
regulations and submit comments and
data that could help improve the
proposal. Comments are solicited on
every  aspect of the regulations,  including
not only the specific pollutant concentra-
tions,  loading limits, and management
practices, but also such aspects  as the
