Residuals Management
and Water Pollution
Control Planning



-------
America's economic growth
is a story of wealth and
waste. Americans are the
world's most economically
productive  people—the
trillion dollar GNP  is  now a
yearly event. And we are
the world's most prolific
producers of solid waste,
more than seven billion tons
of it every year.  In the  past
we largely ignored these
by-products of  our prosper-
ity, burying  or abandoning
them as if  the  earth could
harmlessly absorb this mas-
sive load forever. Now  we
know better. Solid wastes,
also known as residuals,
pollute our  waters, squander
valuable  resources, threaten
health, and  insult our sen-
sibilities.

In  1972  Americans
entered a new period  in
protecting the  Nation's
waters with enactment of
Public Law 92-500—the Fed-
eral Water Pollution  Control
Act Amendments (FWPCAA).
A  cooperative program be-
tween Federal and State
governments, it is an am-
bitious and exacting effort
to halt the growing  de-
terioration of the country's
water quality, including pol-
lution of  water associated
with  solid wastes.

Public Law 92-500 created,
for the first time, a national
water  pollution  control pro-
gram, The law covers  all
navigable waters of the
United States and  has  two
broad  purposes:

•  By  July 1983, to achieve,
wherever possible,  water
clean  enough to permit
swimming and other recrea-
tional uses and to  protect
fish,  shellfish,  and  wildlife.

•  By  1985, to eliminate
the discharge of any pol-
lutants into the Nation's
navigable waters.

The program  contains
several major  elements. It
expands State responsibilities
for setting water quality
standards designed to
achieve the  1983
national goal  of  "fishable
and swimmable waters." The
law creates a national per-
mit program to limit pol-
lutants discharged by in-
dustry and municipalities
into navigable  waterways. It
creates  "national  perform-
ance standards," applicable
to all industrial and muni-
cipal  dischargers, which
establish  minimum effluent
treatment methods. State
and Federal governments
are required to control "non-
point" pollution— that is,
diffuse sources of water
pollution  such as storm-
water runoff, sedimentation,
and  agricultural wastes.  The
law creates a comprehen-
sive  planning  program at
four levels to assure future
control of water pollution:
municipal, areawide,  State,
and  regional. Most major
programs  have compliance
deadlines. Finally, the law
strongly  encourages the
control and reuse of solid
wastes associated with water
pollution. The effective
management of these wastes
is essential to achieving  the
broad goals of the new na-
tional program.

208 Planning
                              Nonpoint Pollution
One  of the most important
programs in Public Law 92-
500  is Areawide Waste
Treatment  Management,  de-
scribed in Section 208. This
program, unique  in Federal
pollution  legislation, is
charged with developing a
special strategy to deal with
the complex pollution prob-
lems  found both  in  urban-
industrial areas and else-
where in  a given  State. The
208  program requires State
and local governments to
work witfi EPA in planning
and carrying out  a variety of
measures to identify,  con-
trol,  and reduce  water pol-
lution sources.
From the time its pre-
liminary  arrangements are
approved by EPA, each 208
State and areawide agency
has  two  years to draw up
a water quality management
plan  for  each designated
area. This  planning  proce-
dure  is fully funded by Fed-
eral  grants. The plans must
accomplish specific goals.
These include:
A. Identifying  all  wastes
generated in the area and all
treatment works necessary
to handle municipal and in-
dustrial wastes over the
next  20  years;
B; Analyzing proposed alter-
native treatment  systems,
land  acquisition  needs,
and  the necessary collection
and  storm sewer  systems, as
well  as developing a
strategy for financing all
elements  of  the  treatment
system;
C. Developing  a  regulatory
program to control the
modification and construction
of municipal treatment
works, ensuring that any
industrial  discharges enter-
ing these  facilities meet
pretreatment standards, and
identifying the  agencies re-
sponsible for such regulation;
and
D. Creating procedures to
control nonpoint sources of
pollution,  saltwater intru-
sion,  the  disposal of all
wastes (including  solid
wastes in  landfills), and
the disposal of  sewage
sludge.
These 208 plans must be
compatible with other State
and local water resource
plans required by Public Law
92-500.
Governors must identify the
agencies responsible for
implementing the 208 plans
after  .their completion. The
agencies are responsible for
continually updating  and
modifying these plans to
achieve the objectives of
Section 208.  The test of the
program's success will be the
feasibility of  its plans. The
program aims  to translate
Federal and  State water
quality standards  into work-
able management strategies.
Public Law 92-500 requires
that all water quality man-
agement plans created under
Section 208 contain  provi-
sions for controlling nonpoint
pollution sources or  activi-
ties. State and areawide 208
agencies must  identify all
the sources of such pollution
within their jurisdiction and
set feasible procedures and
methods to control them.
The plans  must specifically
deal with:

1. Agriculture and silvicul-
ture  (forest  management);

2. Mine-related wastes;

3. Construction; and

4. All  other wastes  that
could affect water quality.

Beyond this,  in order to
protect ground and surface
water quality,  the law also
requires  that the plans
provide for regulating the
disposal  of pollutants on
land—a provision that may
include  nonpoint  pollution
sources not specifically
identified elsewhere in the
law.

The Resources Conservation
Recovery Act.

Late  in 1976, Congress
enacted  a  new solid  waste
management law which  is
likely to influence the 208
program. The legislation,
called the  Resource  Con-
servation and  Recovery Act,
requires that EPA work with

-------
                              Residuals and Water
                              Quality
State and local governments
to achieve more effective
national  waste  control.  By
June, 1978, the generation,
transportation, and disposal
of all wastes identified  by
the EPA as hazardous must
be regulated by permits
issued through the States or
the EPA.

The  law  also requires the
States to prohibit the land
disposal  of solid wastes
except in sanitary landfills
after October, 1983.  Other
provisions require States to
create plans for areawide
management of solid wastes
and  for  resource  recovery
where such  planning is
appropriate.  Federal  grants
are authorized for planning
and  implementing this
program. The goals of  this
new law are  complementary
to the approaches to waste
management under Section
208.  Elements of the new
program may become part of
the 208 planning process; in
this case, some 208  State
and areawide agencies may
assume  the  responsibility
for planning  and implement-
ing parts of this new
program.
EPA defines residuals as
"those solid, liquid, or
sludge substances  from
man's activities in the urban,
industrial,  agricultural,  and
mining environment not
discharged to  water after
collection  and necessary
treatment."  Residuals is a
particularly  apt term for
such pollutants because they
are leftovers. They may also
be  called  solid waste
although  some residuals
(sedimentation, for  instance)
do  not accumulate  in large
waste piles where they may
be  easily discovered and
examined.  One common
form of residual is  familiar
to almost  all Americans:
the materials ending up  in
the trash barrel and garbage
dump. Most, however,  are
unseen or  ignored by the
average citizen—the  sludges
resulting  from wastewater
treatment,  for example.
Residuals  directly  affect
present or future water
quality in  many of the
Nation's most populous
areas. Their control  will be
an  important—and  some-
times crucial—component
in many 208 plans.  Public
Law 92-500 requires the
regulation  of residuals in
water quality  management
plans whenever this  waste  is
likely to degrade water
quality.

The law spells out specific
requirements for  208
planning  agencies  in this
respect. For example, no
sludge from a  municipal
treatment plant that would
affect water quality may be
disposed of without an EPA
permit.  Agencies must
identify and control farm,
silviculture, mine, and
construction wastes con-
tributing to water quality
deterioration. They  must
also create processes to
control  disposal of residual
waste and pollutants on land
or in excavations to protect
water quality.

This concern  with residuals
stems from  an awareness
of their great  pollution
potential.  Sewage sludge,
for instance,  can be  a
potent water contaminant.
When untreated  sewage
sludge is deposited in land-
fills  (even in high quality
sanitary landfills), a multi-
tude of contaminants,
including nitrogen com-
pounds, coliform bacteria,
and  other organic materials,
may leach into the soil and
subsurface waters or  affect
surface  water through runoff.
Methane gas  from the
decomposition  of organics
in sludge  may  accumulate.
Various  toxics and pathogenic
agents may  breed  in a
decaying landfill  and  threaten
public health.  Sewage solids
dumped at sea may contain
pathogenic agents which
contaminate shellfish.

Waste in  landfills is more

than aesthetically  repellent;
rain, snow, and surface
waters may wash from such
debris  a multitude of  con-
taminants—including
bacteria  and  viruses, sus-
pended solids,  nutrients,
metals, pesticides, and
persistent organic toxic
compounds—all  of which
can  find their way into
rivers,  streams,  and lakes.

The  need to control mine
wastes, another major
source of water degradation,
will  become increasingly
imperative because  surface
mining for coal will vastly
expand in the next decade.
The spoil  produced from
coal surface mining contains
many pollutants: iron
pyrite ("fool's gold") that
dissolves  in surface  and
subsurface waters to pro-
duce  sulfuric  acid; heavy
sedimentation, which creates
turbidity  and increases the
danger of flooding by
lowering   the carrying
capacity of stream beds-, and
various  ferrous  compounds,
which poison  plant and
animal life.
Waste Treatment Sludges

Sludges are solids removed
from waste water in com-
munity treatment plants that
must be further treated to
remove many  harmful
organisms.

Sometimes they are  treated
anaerobically by bacteria
which  "digest" the sludge
and remove most of  the
dangerous organisms. The
harmful elements, together
with most of the water,  also
may be removed by  air
drying  or vacuum filtration
in large  drying drums.
After it has been detoxified,
the sludge either may be
removed to a sanitary
landfill, recycled in the
water  treatment system
itself,  used for land  recla-
mation, deposited in waste
disposal  ponds, dumped in
the ocean far offshore, or
incinerated.

Residential  and Commercial
Wastes

These  include glass,  plastic
and metal containers, food
remnants,  paper products,
toothpaste tubes, discarded
appliances, auto bodies,
food industry  processed
wastes, and many other
products. Most of these
solid wastes are deposited in
landfills,  incinerated, or
hauled to sea and dumped.

-------
 Industrial Sludges and
 Processed Wastes

Many industries treat their
own  waste waters and
generate sludges.  Industrial
processed wastes  also may
include  paper pulp,  cinders,
fly ash,  combustible  and
noncombustible  solids,  toxic
chemicals, metal  scraps,
lumber, used  containers,
and other materials.
Agriculture solid wastes

The  largest  volume of non-
point pollution in the
United States is  the  refuse
from  agriculture.  Feedlots,
pastures,  grazing  land, and
other areas  of animal  hus-
bandry produce enormous
amounts  of  metabolic waste.
Much of  the fertilizer used
in agriculture dissolves in
runoff waters; plant debris,
silviculture materials, herbi-
cides, and other sources
produce  significant  solid
wastes. Even though  these
activities may not occur  in
urban areas, the  materials
carried from them by
surface and underground
waters may affect urban
water quality.

Mine wastes

Mining,  particularly  surface
mining, affects water
quality adversely  through
sedimentation, the disrup-
tion of underground water
systems,  and the contamina-
tion of streams, lakes, and
rivers by acid drainage
from exposed  mining
wastes.
Sedimentation

Heavy sedimentation is
caused  by soil cultivation,
timber cutting, strip mining,
overgrazed pastures, road
building  and other con-
struction activity.  A con-
struction site, for  instance,
may contribute 2,000 times
more sediment than forested
terrain and 200 times  more
than grassland.

-------
A Growing Problem
                              Recovered  Resources
In 1972, waste treatment
facilities in the United
States  were producing
sludge at a rate of about
4,700,000 dry  tons a year;
by 1985, this figure will rise
to 6,655,000 tons. Process-
ing and disposing of these
sludges accounts for more
than half the annual
operating and maintenance
costs of most wastewater
treatment facilities. About
a  third of the capital cost
of the average waste treat-
ment facility can be  attri-
buted  to  sludge  manage-
ment equipment.  Most of
this cost is ultimately borne
by taxpayers.  Since most
communities have  given
little attention  in the past
to recycling sludges or
otherwise realizing some
income from  their reuse,
this public  investment in
sludge management  has
seldom produced  its full
potential return.  As the
number and efficiency of
community treatment
facilities increase, sludge
will constitute a  steadily
rising  cost factor in  com-
munity waste management
programs.

Residential  and  commercial
wastes also grow. The
Nation's municipalities cur-
rently spend more than $5
billion  yearly to  haul away
and process these wastes.
These  wastes,  amounting to
almost 17 times the volume
of sludges  produced  in
waste treatment facilities
have seldom been managed
imaginatively or efficiently.
Customarily, they are hauled
to landfills or buried  at
sea.  Land for waste disposal,
however, is becoming  in-
creasingly  scarce and  costly
and  sea disposal  poses
environmental problems.
Past management  of
sludges and solid wastes
has imposed a double cost.
There is the tangible  treat-
ment cost and also  a  lost
income—in money,  reusable
materials, and energy—
when these residuals are not
recycled. One attractive
alternative to ocean dumping
or landfilling  for waste
treatment sludges might  be
their reuse as fertilizer.
Sludges sometimes can be
used for agriculture pur-
poses because they contain
useful  plant nutrients such
as nitrogen, phosphorous,
and  potassium. Some types
of sludge may  not  be
suitable for  this purpose
because they  contain
contaminants.  The  cost of
preparing sludge as
fertilizer may  be prohibitive
in some instances, but the
possibilities  have seldom
been explored.

The  recovery value in
community garbage is
potentially  great. EPA
estimates that from the 134
million  tons of refuse
thrown  away by Americans
each year, the following
materials could be reclaimed:

•  11.3  million  tons of iron
and steel

•  860,000 tons of aluminum

•  430,000 tons of  other
metals  (mostly  copper)

•  13 million tons of glass

-------
                                                           Managing
                                                           Residuals:  A "Best
                                                           Management" Plan
•  burnable organic mate-
rials equal to one-half
million barrels of crude oil,
or roughly 70%  of the
annual estimated yield  of
the Alaskan  North Slope oil
reserves.

The potential energy re-
coverable in common
garbage  is particularly
notable when the Nation is
becoming concerned  about
the future availability of
fossil fuels and other
energy sources.  Not only can
energy be generated by
burning organic  materials  in
garbage, but some metals
can be obtained  from
residuals with less energy
expenditure than is required
for the initial mining and re-
fining. For example, it takes
20 times as much energy
to get a pound of aluminum
from bauxite ore as from
urban solid waste; a ton of
steel  obtained from recycled
municipal waste  requires
almost three-quarters less
electric power to produce
than the same amount  pro-
duced from iron ore.

Often, there are practical
difficulties in recycling resi-
dential and commercial
wastes. Recycling is by no
means a panacea to be
prescribed for every com-
munity seeking better ways
of waste management. How-
ever, many urban areas are
successfully recycling
refuse. The City of San
Diego recycles 200 tons of
refuse daily,- through a
combustion process called
"pyrolysis" it obtains one
barrel of fuel oil from an
average ton of refuse and,
additionally, recovers 140
pounds of ferrous metals
and  120 pounds of glass. St.
Louis, Missouri,  is convert-
ing much of its municipal
waste into electricity. Some-
times a joint effort between
government and industry
can  produce effective re-
cycyling. The  Boston North
Shore System at Saugus,
Massachusetts, burns 1,200
tons of  refuse a day to gen-
erate steam. A private
company built and operates
the  plant, which receives
refuse from 10 municipalities
 under contract to  produce
 a regular supply of com-
 bustible  solid waste. Urban
 areas, especially, often
 generate the large volume of
 solid wastes and achieve
the economies of scale nec-
 essary to make solid waste
 recycling attractive. This
 is particularly significant
 when considering recycling
 for residuals management
 in 208 planning.
Confronted with many kinds
of residual wastes and a
multitude of possible man-
agement strategies, 208
planners face an imposing
problem: What procedures
should be  chosen?  If
control strategies for specific
residuals are combined  in
different ways,  the range of
options  will seem formid-
able. However,  regulations
developed to implement
Public Law 92-500  some-
what simplify this task by
providing  some guidelines.

EPA regulations require
that EPA and the States work
together with 208 agencies
to develop  the "best man-
agement practice" (BMP)
for residuals. A BMP is de-
fined as "a practice,  or
combination of practices,
that is determined by a State
(or a State  or areawide 208
agency) after problem
assessment, examination of
alternative  practices, and
appropriate public  participa-
tion to be the most effec-
tive, practicable means of
preventing  or reducing the
amount  of  pollution gen-
erated by nonpoint sources
to a level compatible with
water quality standards."
This means that any
residuals management
strategy developed  under
208 planning must meet at
least four general tests:

-------
                                                            The  Citizen's Part
1.  It should manage  pollu-
tion generated by nonpoint
sources;

2.  It should be compatible
with water quality goals;

3.  It should effectively
prevent or reduce pollution;
and

4.  It should be practicable—
that is, it should  be designed
with careful attention to
technological, economic,  and
institutional factors.

As a practical matter,  it
should be able to meet the
following  objectives:

A. Reduction of water flows
by eliminating promiscuous,
illegal, or accidental dumping
of wastes  and preventing
surface and ground water
contamination from existing
or  planned land disposal
operations.

B. Development  of the  most
economical disposal  plan.

C. Stabilization of wastes.

D.  Reduction, recovery, and
recycling.

E.  Assure that the institu-
tions will  have  proper
authority, jurisdiction,  per-
sonnel, and financing and
that charges for residual
waste  disposal  are related
to the benefits of the
services.
Best management plans will
vary because communities
have different problems and
varying means for solving
them. One community may
reduce sewage sludge by
selling a  portion of it for
commercial  or farm use;
another may find it more
practical  to dry, detoxify,
and  haul the sludge  to  a
sanitary  landfill. Both
solutions may meet the
BMP criteria.

EPA encourages innovation,
flexibility, and imagination
in the development of BMP's
for residuals management.
Past experience should
not become the sole test
of proposed  strategies. Exist-
ing arrangements, laws, or
governmental processes may
need to be changed  to
permit improved practices.
Management  strategies also
should encourage the flow
of accurate information  to
the public and ample op-
portunity for public involve-
ment. Planners  should  have
an attitude of openness,
responsiveness,  and  concern
for creative  approaches.
There are sound reasons
why Public Law 92-500 and
EPA regulations insist that
citizens be informed and
helped  when  participating
in the 208 planning  process.
Citizens can make a valuable
contribution to residuals
management in  several
ways-.

A. They can help define the
social impact of proposed
programs.

Citizens know their com-
munity  culture,  interests,
and sentiments. This insight
can be invaluable to planners
and public officials.  Spe-
cifically, citizens can often
suggest:

• how  much a community
is willing to pay, and how,
for residuals management;

-------
                              Who Should
                              Participate?
                              Getting  Involved
•  what alternatives are
preferred; and

•  what "trade-offs" are
acceptable.

In short, citizen involvement
can keep the planning
process practical and
responsive to the  com-
munity.

B. They can become an
articulate, active constituency
for a residuals management
program.

Once citizens understand
its importance, they can
often keep public  officials
and planners alert  to good
residuals  management.
Elected officials are espe-
cially responsive to or-
ganized, vocal interests.
Without citizen activity, it is
easy for public officials and
planners to defer to other
problems.

C. They can help carry out
programs.

When citizens can  contribute
to a  residuals program,  they
are more likely to  support
it. Knowledgeable, con-
cerned citizens help assure
success.

Making such a contribution
requires more  than activity
and  interest. Citizens
need, first, to become in-
formed about the- residuals
problem in  their community
and about the work of 208
planning agencies.
In nearly  every community
there are business, profes-
sional,  minority, environ-
mental, agricultural, service,
labor, public interest groups.
Contact with these groups
can often lead to communi-
cation  with more  special-
ized interests.

In any metropolitan area,
the number of groups  af-
fected  by the 208 program
will be large; in the Wash-
ington, D.C. metropolitan
area, for instance, the
areawide 208 agency has
identified  115  existing  or-
ganizations with a potential
concern for local water
quality management. Al-
though it is unrealistic to
suppose that all organiza-
tions affected  in some man-
ner by local water quality
programs will  wish to par-
ticipate in the 208 program,
many will wish  to be in-
formed about the program
and  some, once contacted,
may develop an  interest.
Whom Do I Contact?

One route to gain informa-
tion about public invove-
ment in residuals planning
is through the designated
State or areawide 208
agency. These agencies
must provide citizens with
this information.  Citizens
will  usually find the  most
useful agency contacts to  be
the Public Participation Co-
ordinator and the Citizens
Advisory Group.

Public Participation
Coordinator

Most agencies have a staff
member responsible  for co-
ordinating public involve-
ment activity. This person
may be called the "Public
Participation   Coordinator,"
"Public  Involvement Officer,"
or something similar. This
individual can ordinarily pro-
vide considerable material
and other information.
Often he/she  can direct
the citizen to others directly
related to the citizen's
interests.

Citizen Advisory Committee

This is composed of  spokes-
persons for  local interests.
Members whose job is to
evaluate the broad purposes,
alternatives, and  procedures
for the  208 plan. This
committee commonly  as-
sumes some  responsibility
for encouraging  and assist-
ing citizen involvement.

A Final Word
Few things affect  us  more
directly than air and water
quality.  Residuals  planning,
like other elements in the
208 program, will help
to  shape our future en-
vironment. For the first
time,  this country has
embarked upon a deliberate,
ambitious effort to plan  our
environmental future in a
manner that  protects price-
less natural resources for
ourselves and coming  gen-
erations. This will be a
difficult, lengthy, often  con-
troversial,  and costly en-
deavor. It is also an essen-
tial  undertaking worthy of
our interest and par-
ticipation.

Some Significant  Terms
activated-sludge process-
use of biologically active
sewage sludge to hasten the
breakdown of organic matter in
raw sewage during secondary
treatment.

discharge of a pollutant—any
addition of any pollutant to
navigable waters from any point
source; any addition of any
pollutant to the waters of the
contiguous zone or the ocean
from any point source other than
a vessel.

effluent—a substance that
flows outlthe treated or
untreated liquid  that flows out of
a waste treatment plant, a sewer,
or an industrial ouliall.

effluent limitation—any
restriction (including schedules
oi compliance) established by a
Stale or EPA on quantities, rates.
and concentrations of chemical.
physical, biological, and other
constituents which are
discharged from point sources
into navigable waters, the waters
of the contiguous zone, or the
ocean.

eutrophication—an aging
process in lakes, during which
the water becomes overly rich in
dissolved nutrients, resulting in
excessive development of algae
and other microscopic plants
causing a decline in levels of
dissolved oxygen (DO).

ground water—water in the
porous rocks and soils of the
Earth's crust: a large proportion
of the total supply of fresh water.
industrial user—any industry
that introduces pollutants into
public sewer systems and
whose wastes are treated by a
publicly-owned treatment
facility.

land disposal method —
advanced waste treatment that
uses soil, air, plants, and
bacteria to remove pollutants
from waste water.  It includes
tour basic processes:
pretreatment to screen out large
solids: chlorination and
vegetation in the soil; spraying
over cropland where vegetation
and micro-organisms in the soil
remove additional pollutants;
and reclamation by wells or
drain tiles.

landfill—any land site to which
solid waste is hauled and
dumped. Many landfills are
neglected or poorly managed.
resulting in considerable
contamination of surface and
ground waters by runoff. Odors,
fires, vermin, and other
pathogenic agents may also
thrive in badly managed landfills.

navigable waters—the waters
of the United Slates, including •
Ihe territorial seas, and intrasiate
waters.

nonpoint source—any
unconfined area from which
pollutants are discharged into  a
body of water, i.e.. agricultural
runoff, urban runoff, and
sedimentation from construction
sites.
performance standard—a level
of control for a given pollutant
from a given source as defined
by Ihe EPA. Public Law 92-500
requires the EPA to specify what
these "performance standards"
shall be for major dischargers of
pollutants inlo Ihe Nation's
navigable waters. A
performance standard must be
set by the EPA according to the
"best available demonstrated
control technology, process,
operating methods, or other
alternatives including, where
practicable, a standard
permitting no discharge of
pollutants."

permit—a legally binding
document issued by a State or
Federal permit agency to Ihe
owner or manager of a point
source discharge. The permit
document contains a  schedule
of compliance requiring the
permit holder to achieve a
specified standard or  limitation
(by constructing treatment
facilities or modifying  plant
processes) by a specified date.
Permit documents also specify
monitoring and reporting
requirements to be conducted
by the applicant. All permits
issued are valid for a maximum
of five years.

point source—any discernible.
confined, and discrete
conveyance, including . . . any
pipe, ditch, channel, tunnel.
conduit, well, discrete
operations, or vessel, or other
floating era!!, from which
pollutants are or may  be
discharged.

-------
pollution—(he man-made or
man-induced alteration of the
chemical, physical, biological,
and radiological integrity of
water making it less desirable for
the propagation of balanced
indigenous populations of fish,
for recreation, industry, or
wildlife uses.

pollutant—waste discharged
into water including: dredged
spoil, solid waste, incinerator
residue, sewage, garbage,
sewage sludge, munitions,
chemical wastes, biological
materials, radioactive materials.
heat, wrecked or discarded
equipment, rock, sand, cellar
dirt, and industrial, municipal.
and agricultural waste; but not
including, sewage discharged
from vessels nor material
injected into wells in connection
with  the production of  oil and
gas.

pretreatment—any process
used to reduce the pollutant load
before the waste is introduced
into a sewer system or delivered
to a  treatment plant.

receiving waters—bodies of
water into which waste water
effluents are discharged.

river basin—one of 267 major
and  minor basin areas drained
by a river and its tributaries.
sanitary landfill—a site, used
for the land disposal of refuse.
managed so thai nuisances or
hazards to public health and
safety are avoided. The refuse is
confined to the smallest
practical area, is reduced to the
smallest practical volume and is
covered with a layer of earth at
the conclusion of each day's
operation, or more frequently if
necessary. Such landfill usually
reduces the contamination of
surface and ground waters
resulting from waste disposal.

sewer—any pipe or conduit
used to carry sewage or storm
water to treatment plants or
receiving waters.

sewer, combined—sewer that
carries both waste water and
storm water.

sewer, interceptor—a sewer
which collects the sewage from
the main and trunk  sewers and
carries them to points of
treatment or discharge.

sludge—the solids removed
from waste  water by
sedimentation and precipitation;
often presents a problem of
ultimate disposal
toxic pollutants—a pollutant or
combination of pollutants
including disease-causing
agents, which after discharge
and upon exposure, ingestion.
inhalation, or assimilation into
any organism either directly or
indirectly cause death, disease.
cancer, genetic mutations.
physiological malfunctions
(including malfunctions in
reproduction), and physical
deformities in such organisms
and their offspring.

turbidity—a cloudiness or
discoloration of water as a result
of suspended solids. Most
commonly, turbidity is caused by
dissolved sediment and
produces a "muddy"
appearance.

water quality standard—a plan
for water quality management
specifying: the use (recreation,
fish and wildlife propagation.
drinking water, indusirial. or
agricultural) to be made of the
water; criteria to measure and
protect these uses;
implementation and
enforcement plans; and an
antidegradation statement to
protect existing water quality.

water quality criteria—the
levels of polluiants that affect the
suitability of water for a given
use.
