            RESEARCH REPORTING SERIES
Research reports of the  Office  of  Research  and
Monitoring,  Environmental Protection Agency, have
been grouped into five series.  These  five  broad
categories  were'established to facilitate further
development  and  application   of   environmental
technology.   Elimination  of traditional grouping
was  consciously  planned  to  foster   technology
transfer   and  a  maximum  interface  in  related
fields.  The five series are:

   1.  Environmental Health Effects Research
   2.  Environmental Protection Technology
   3.  Ecological Research
   4.  Environmental Monitoring
   5.  Socioeconomic Environmental Studies

This report has been assigned to the ENVIRONMENTAL
PROTECTION   TECHNOLOGY   series.    This   series
describes   research   performed  to  develop  and
demonstrate   instrumentation,    equipment    and
methodology  to  repair  or  prevent environmental
degradation from point and  non-point  sources  of
pollution.  This work provides the new or improved
technology  required for the control and treatment
of pollution sources to meet environmental quality
standards.

                         INTRODUCTION
During the early development stages of the animal feeding industry,
there was little or no emphasis placed on pollution control. At that time,
the majority of livestock feeding units were located with disregard for
pollution potentials.  In fact, many were located to take advantage of
natural drainage ways to transport solid and runoff-carried wastes to
the nearest stream. The cost of pollution control structures now required
at these sites can exceed the cost of changing sites.  Recent awareness
of environmental degradation coupled with  ever increasing sizes of
individual feedlots and related decreases in available land area for
wastes disposal have placed emphasis on the environmental hazards
associated with livestock feeding. Wastes handling and disposal prac-
tices have, in the past, resulted in pollution of surface ( and in some
instances ground)  waters which in many cases were accompanied by
extensive environmental damage and fish kills.
Environmental pollution can be significantly reduced in the initial
planning stages by adequate facility planning,  management, and, most
importantly, by proper site selection.  Climatic, topographic, and
local weather extremes of the general area, selected with regard to
economic and market factors, should be considered when planning the
type of feeding facility. A site should then be selected which would
decrease the pollution  potentials and be readily adapted to necessary
controls.  Many of the  natural and artificial pollution controls  discussed
herein may initially appear costly; however, their long-range value
can result in considerable savings. The emphasis of this report is
placed on those basic considerations of site selection which are com-
patible with pollution control designs and which lessen the impact
of other environmental hazards.  This report should be used when
locating a new facility  or when modifying an existing feedlot.  Many
of the concepts and ideas presented herein cannot be economically
superimposed on an existing operation. A  more comprehensive treatise

-------
of animal wastes management may be obtained from the Beef Wastes
Management Manual which is in preparation and will, upon publication,
be available from the Environmental Protection Agency, National Animal
Feedlot Wastes Research Program.

-------
                    BASIC CONSIDERATIONS
Many considerations influence the selection of a feedlot site which
will be suitable for adequate pollution control and protection of the
surrounding environment.  These considerations may be grouped into
six categories:
                      Regulations
                      Spatial Requirements
                      Topographic Features
                      Microclimates
                      Soils and Geologic structures
                      Social Considerations
Although these categories are interrelated, each will be discussed
individually.
Regulations
Laws written to protect each individual in our society have been passed
at nearly all levels of government.  Regulations imposing responsibility
for the quality of the environment and the use of both renewable and
depletable resources have been imposed on all who use them.  This
involvement has placed a responsibility for pollution control and environ-
mental enhancement on each individual and corporation presently
designing, developing, or managing a livestock feeding facility.
State and local regulations should be carefully studied for they will
in most instances affect feeding facility site selection. Several states
have placed restrictions  on the minimum distance that a feedlot can
be located from surface water, residential dwellings, municipalities,
recreation areas, and arterial highways.  Other states are considering
similar courses of action.  Additional requirements now in effect
may  include storm water runoff control facilities, structures for prevention
 of ground water contamination, storage for solid and runoff-carried
wastes, and specified ultimate disposal procedures. In most cases,
these regulations are controlled by statutory permits issued through
appropriate agencies within state and/or local governments. A list

-------
 of state agencies to be contacted is included at the end of this report.
 Additional information concerning zoning and other local restrictions
 may be obtained from the county officials serving the immediate district.
 Spatial Requirements
 The spatial needs of various livestock feeding units will vary with
 the facility type and climate in which it is located. The total area
 required for an integrated system may be determined as the sum of the
 areas required for each of the following components:
     1.  The production area,
     2.  Extraneous storm water runoff diversion ditches,
     3.  Storm water runoff collection and retention structures,
     4.  Wastes storage,  treatment, and ultimate disposal sites,  and
     5.  Buffer zone around the feeding facility and/or ultimate
        disposal site.
    Estimates for the area needed by each component are:
    1.  The  production  area requirements can be based on the pen area.
Pen area designs vary from 20 to 200 square feet per animal. An addi-
tional 15 percent of the pen area is needed for alleyways, feed bunks,
and animal shipping and receiving docks.  Mills, scales, office,
housing, driveways, and parking  space require an additional tract
20 to 30 percent of the size of the pen area.
    2.  Extraneous storm water  runoff diversion ditches  are con-
structed to reduce the volume of contaminated runoff which must be
collected and disposed of or treated.  Diversion ditches should be
constructed around all areas to prevent uncontaminated storm water
runoff from contacting manure and other pollutants.  These are the
feeding, feed preparation and storage, solid manure  storage, and
runoff wastes retention areas. The amount of extraneous storm water
runoff to be diverted may be reduced by selecting a site which has
a minimum of up slope drainage area.  Nevertheless,  overdesigning
the capacity of the diversion structures (where rain storms of high
intensity occur) could be an economical safety factor.  In many  areas

-------
these structures are built around covered facilities primarily to maintain
 a dry wastehandling area near the facility.  Runoff diversion structures
generally require an area which is less than or equal to five percent
of the total pen and runoff collection area.
    3.   Storm water runoff collection and retention structures
are designed to retain and provide temporary storage for all storm
water runoff which comes in contact with manure and other pollutants.
The size of these structures is dependent on the rainfall of the region
and resulting runoff from the facility.  Smaller runoff control structures
may be used on a paved open feedlot more successfully than on an
unpaved lot having the same animal population, for increased animal
densities are possible on paved surfaces. Several states regulate
the size of sedimentation and retention ponds and the runoff retention
time in each structure.  These structures should, in the absence of
regulation, be designed to retain all runoff resulting from the rainfall
from a 10-year 24-hour design storm or its equivalent.  The area needed
for these structures will range from 2 to 15 percent of the total pen
area depending on structure depth and volume of rainfall resulting
from the design storm.
    4.  Wastes storage, treatment,  and ultimate disposal sites
are of major concern when computing the area needs for beef animal
production units.  The amount of acreage required for these uses
will depend on the volume and moisture characteristics of the wastes
generated, which in turn are dependent on the type of facility and
wastes management system design.  Both runoff and solid manure
wastes are generated from open feedlots.  On the other hand, wastes
generated from total confinement facilities are in the form of a slurry
which contains both manure and urine. The volume of these slurries
which must be treated or disposed of is controlled by the number of
animals on feed, type of feed, and in some instances by the volume
of dilution water added.  The amount of solid manure wastes produced
in open feedlots is dependent on the  number of animals, type of feed,
and pen surface moisture conditions; volume of runoff wastes originating

-------
from open feedlots is dictated by drainage area, amount and intensity
of precipitation, and pen surface conditions.
Wastes management facilities will be discussed according to moisture
characteristics as follows:
                      Runoff wastes
                      Solid manure wastes
                      Slurry wastes
Although the basic site selection concepts concerning waste management
are applicable to beef production facilities, the general precepts should
be considered for the whole of the animal production industry.
Runoff wastes control involves the integration of runoff retention and
storage structures with a treatment method and ultimately with a means
of disposal.  The land area requirements of runoff retention have been
previously discussed.
Because of the extreme pollution potential of animal wastes, conven-
tional municipal waste treatment designs are not considered to be
economically feasible for use by beef cattle feedlot operators without
significant modifications.
Spray runoff treatment, a promising treatment method recently demon-
strated, may be used to treat runoff in areas where freezing conditions
exist for less than two months during the year.  The land area needed
for this method ranges from 20 to 50 percent of the pen area plus an
additional 15 percent for a pretreatment storage structure.
Irrigation of crops, pasture, or wooded land is the most practical
means of runoff disposal in most climates. Desirable application rates
have been found to range from 4 to 8 inches per year. The land area
needed for irrigation of runoff is equal to the volume of runoff generated
from the feedlot annually divided by the appropriate application rate.
The spatial requirements of a runoff irrigation system must often include
a pre-irrigation storage pond to facilitate coordination of runoff appli-
cations with crop and soil moisture conditions  and to avoid  application

-------
of runoff to frozen or snow covered surfaces.  The acreage required
for this storage pond will range from 0.1 to 0.3 times the pen area.
Maximum runoff disposal rates may be  necessary during periods of
extreme weather conditions resulting in occasional crop damage.  The
additional cost for ownership of the necessary real estate by the feedlot
operator may be justified to avoid conflicts.
Areas in the Western United States, where the moisture deficit (evapo-
ration minus precipitation) is greater than 10 inches, have a high
potential for using evaporation  for ultimate disposal of liquid wastes.
An evaporation pond area of approximately one-third the size of the
total feedlot will be needed in a region  of a 40-inch moisture deficit.
When considering this disposal method, the potential for ground water
contamination and other problems must also be investigated.
The following equations may be used to estimate the total area needed
to utilize runoff wastes management systems incorporating  irrigation
or evaporation disposal techniques and spray runoff treatment methods.
These equations are based on the fact that: "A " equals the total
area for management of runoff wastes;  "P" equals the area  of the runoff
retention structure  which is 0.02 to 0.15 times the total pen area in
acres;  and "S," which is the additional storage area needed to manage
the disposal system, equals 0.05 to 0.15 times the pen  area. Annual
runoff from feedlots may be 2 or 3 times that of adjacent cropland.
Annual runoff values for a specific location may be obtained from  the
local office of the Soil Conservation Service or from a consulting engineer.

Example:  Assume that one wishes to build a  10,000-head capacity

including feed bunks, alleyways, etc. in a 30-inch rainfall area with
6 inches of annual runoff and a 10-inch moisture deficit (40-inches
evaporation per  year).  Considering the maximum space-consuming
conditions, the estimated land area requirement for irrigation disposal
using Equation (1) is 60 acres; for spray runoff treatment using Equation
(2) is 37 acres;  and evaporation disposal using Equation (3) is 25 acres.

Solid manure wastes generated from animal feedlots are one of the
most critical wastes disposal problems confronting the animal feeding
industry. The lack of long-term site availability  for solid manure
disposal can create an impassible obstacle to  efficient feedlot operation.
Land application of solid manure, as it is with runoff, is the most prac-
tical method of disposal known to present technology.  The selection of
a feedlot site should include extensive investigation of the land area
available for manure disposal.
Fewer problems  will be encountered by the feedlot owner who owns
sufficient land area for manure disposal. However, total ownership of
disposal areas, especially with larger lots  (5,000 to 10,000 head plus)
may not be practical, and firm advance commitments for manure disposal
                                8

-------
should be obtained before the first land purchase or construction dollar
is spent.  These commitments, for example, may be in the form of land
leases with renewal options or cooperative contracts between feedlot
owners and grain growers which would be in the best interest of all
concerned parties.  These may require grain growers to accept or
buy an allotment of manure in return for special grain prices or manure
hauling and spreading services.
The amount of land area needed for solid manure disposal is equal
to the amount of manure cleaned from the feed pens divided by the
application rate.  The amount of beef cattle manure cleaned from feed
pens ranges, on a dry weight basis, from 6.5 to 12 pounds per day
per animal, depending on animal size, amount of roughage in the feed,
and the percentage of soil removed from the pen surface with the manure.
The amount of manure to be handled and the disposal  land area may
be reduced by carefully cleaning the pens to leave from 2 to 3 inches
of manure packed on the pen surface, thus reducing the amount of
soil to be handled with the manure.
The quantity of manure cleaned from a feedlot may be estimated by
using the  following equation;  where "M" equals tons of dry manure
per year:
., _ (animal days/yr.)  (Ibs. manure produced/animal day)
              factor to convert pounds to tons
,., _ 365 days/yr. (feedlot head capacity) (6.5 to  12 Ibs. manure/animal  day)
  =                            2,0001 Ibs./ton
Example:  Assuming that each animal produces a dry  weight equivalent
of 12 Ibs.  of manure daily, the solid manure cleaned from a 10,000 head
beef feedlot in one year  according to equation (4) equals approximately
21,900 tons.
,„%  x,   365(10,000)(12)    ,, Qf.n  .   ,
(4)  M =	v 2^000 —  = 21,900  tons/yr.

The application rate of solid manure ranges from 10 to 40 tons  dry
weight per acre depending on the type of crops,  soil  types, and rain-

-------
fall amounts .  The amount of land area required to dispose of solid
manure "A  " is equal to the volume of manure to be disposed of
annually, "M" in tons per year, divided by the annual application rate
in tons per acre "R" or:
Example:  Using the 21,900 tons of manure produced on a 10,000 head
capacity feedlot, which was estimated in the preceeding example, and
a 10 ton/acre/year manure application rate (Figure 1) the estimated
acreage required for manure disposal by using equation  (5) is 2,190 acres,
 (5)  Am=        =2, 190 acres
Frequent pen cleaning and disposal by direct application to crops
can eliminate the need for solid wastes storage .  However ,  the seasonal
nutrient needs of crops and soil moisture conditions in wetter or colder
climates do not correspond to a systematic schedule of wastes disposal
by land application .  The application of solid wastes to saturated or
frozen soils will, like feedlot runoff, create a contaminated storm run-
off problem from the disposal site . Thus , solid wastes storage is a
necessity  in most climatic and agricultural regions . There is wide
variability in the factors  which influence the land area needed for  this
type of storage. In general, one should consider a storage area which
is approximately 15-20 percent of the feed pen area in size  and which
is suitable for the construction of a storage structure which will
eliminate surface and ground water pollution .
Manure slurries  are most commonly produced in total confinement
buildings  with slotted floors and in concrete open feedlots with flush
type manure removal.  Slurries  are generally scraped, flushed, or
pumped from the pen area at regular intervals ranging from daily
to monthly .  Thus , specially designed storage structures are a necessity
to maintain environmental quality between disposal periods .

Either deep lagoons or concrete tanks are used for storage.  Tanks
should be covered to reduce odors and prevent children and animals
from becoming trapped in them; for a given storage volume, tanks
which have straight sidewalls require less area than lagoons, which
generally are designed with sloping sides. Mechanically aerated
oxidation ditches are also used for slurry manure storage and have
been successfully used directly under the slotted floor in hog confine-
ment buildings where they do not require additional land area.  The
primary  advantage of using this process is one of reducing odors.
The basic equations used to estimate spatial requirements for solid
manure disposal on cropland  may be used in estimating the area needed
for slurry disposal.  Manure  slurries are  a total  composite of manure,
as excreted, without the  changes  caused by rainfall leaching.  Soil
application rates, for this reason, should be reduced from the 10-40
tons per  acre suggested for solid  manure wastes  to  10-20 tons per
acre.   Additionally, the daily amount of manure produced is approximately
 60 pounds per animal.  The end result of the decreased application
rate and  greater amount of manure to be handled is a significant in-
crease in the size of the disposal area.
The required amount of land for both solid and slurry wastes disposal
may be greatly reduced by increasing the rate and/or frequency
of application; however,  this should be done only if the feeder has
control of the crops or the land either by leasing or through ownership.
This approach in some cases is uneconomical, but firm wastes disposal
agreements should be obtained from neighboring landowners before
the final  decision is made on a site.
The distance that wastes  must be hauled for disposal should be kept
to an economically feasible minimum.  The economic break point for
hauling distance may be estimated as follows:
  .F-L-S+M-M1
U           H         	
                                12

-------
Where:  D = maximum economic hauling distance; F = value of com-
mercial fertilizer with equivalent amount of nitrogen, phosphorous, and
potassium in one ton of manure in $/ton; L = loading costs in $/ton;
S = spreading costs in $/ton; H = hauling costs in $/ton/mile; and
M = price paid farmer by feedlot owner to accept manure in $/ton;
or M1 = price paid feedlot owner by farmer for manure in $/ton.
Example:  Assume that the nutrient content of a ton of manure is
equivalent to four dollars worth of commercial fertilizer, that it costs
$0.35 per ton to load and $0.90 per ton to spread manure, that the
manure hauling can be contracted for $0.10 per ton/mile and that the
amount paid by the farmer to the feedlot owner for the manure is $1.50
per ton. Then according to equation  (6) the maximum economical hauling
distance is 12.5 miles .
^N  ™   $4.00- $0.35 - $0.90 - $1.50    $1.25    ._ c  .,

                $0.10 per mile           $0.10
A manure irrigation system for pumping a slurry or waste water for
field application costs about one-half  as much as mechanically hauling
and spreading a slurry within one-half mile of the feeding facility.
Thus, a site with an area suitable for irrigating slurries within this
distance could result in considerable  savings for manure disposal.
    5.  Buffer  zone  (green belt) around the feeding  facility.  The
basic purpose of developing a buffer  zone is to reduce or  eliminate the
probability of nuisance complaints from the general public.  Feedlot
operations, in many states,  have received nuisance  complaints  re-
sulting from odors produced on their  facilities .  Specifically, to mention
only a few, beef cattle feedlots in Arizona, Texas, and Kansas and a
hog feedlot in Missouri have received court decisions which were in
favor of the complainant;  some decisions have resulted in cease and
desist orders.
Where odors may be of concern, the buffer zone can approximate
the configuration of an egg with the facility and all odor producing pro-
cesses  centered near the small end (Figure 2).  The actual orientation

                                 13

* size dependent on facility  type,  head  capacity,  and  wastes management practice

-------
of the axis of the area is dependent upon the direction of the prevailing
wind.  The size of the buffer zone, usually from 4 to 20 miles along
its long axis, is dependent on the size of the feeding operation and
type of manure management employed.  Obviously, good drainage
and housekeeping practices  coupled with a prompt disposal schedule
may  significantly reduce the intensity of odors and thus reduce the
size  of the buffer zone.  In some locations  zoning agreements may be
entered into with local governing bodies.  Zoning may stipulate a
specific distance from the operation or a group of feeding operations
which is reserved  for agricultural uses. Such agreements would
allow protection against legal action from residential and recreational
development after a feeding operation is established.
Enough space should be allowed around the facility to act as a "green
belt."  The size of this area  need not be expansive but should be large
enough for a shelter belt or visual improvement vegetative plantings.
Some of this area will be the same as that used for waste disposal
or other feedlot operations.  The concept is especially important in
 areas where the operation may be seen  from major arterial highways.
Topographic Features
Topography (lay of the land) plays an important role in two respects
 for  selection of a feeding site.  The slope and natural drainage to
surface waters of any given  parcel of land governs its value as a
feeding site.  Land which is too flat may be poorly drained, and poor
drainage results in sloppy pen  conditions and increased probability
for ground water contamination.  On the other hand, surface runoff
is difficult to control on land with extreme gradients.
The  second role that topography plays in site selection is basically
one of economics.  Feeding facilities are readily adaptable to sites
which for topographical reasons are marginal for most intensive farming.
Because of the marginal classification these lands often are priced at
a much lower dollar value than is land used for intensive farming.  The
                                15

-------
rugged topography of these sites may create a need for a large amount
of earth moving; however, there are earth moving requirements
associated with all feeding sites regardless of topography. Additional
earth moving costs  should be balanced against the lower land costs.
Topographical quadrangle maps in the 7.5 or 15 minute series are
available for most of the United States from the United States Geological
Survey. Accurate information concerning the contour of the land and
its location with respect to water courses, access routes, residential
and recreational areas may be obtained by careful inspection of these
maps.   Preliminary planning layouts may  be made for several different
sites on topographical maps before making final  site selection decisions.
After selecting a site, a topographical survey with a contour interval
of 1 or 2 feet would expedite the detailed designing of the facility and
processes.
During the evaluation of the topographic suitability of sites, one
should eliminate all those which do not meet, or  cannot be adapted to
meet, the following constraints:
    1.  A minimum of land uphill which will contribute extraneous runoff.
    2.  A slope for the feed pens with a 2 to 6 percent gradient.  Sloppy
pen conditions may occur with less than 2 percent pen slope, and uncon-
trollable runoff may occur with greater than 6  percent pen slope.
    3.  Space with suitable slope and deep soils for construction of
runoff collection and storage facilities.
    4.  An area used for  manure storage, having soil, bedrock,  and
a deep groundwater table which is located away  from natural drainage
channels.
    5.  A dry feedlot access route which  may  be easily maintained for
manure removal during all weather conditions.  Access roads  through
low wet areas or with steep  gradients will cause manure removal problems
during wet and freezing weather.
    6.  A low gradient site for runoff disposal which is located away
from natural drainage areas.

                                 16

-------
Not all of the above constraints will apply to total confinement and
certain other facility designs, but each should always be considered
when appropriate.
A final topographical consideration for site selection is the location
of a facility with respect to surface waters.  Several states have set
control requirements based on specific distances or have developed
mathematical formulae which are to be followed when locating near
surface waters.  This distance will not remove the pollution potential
to a surface water course since travel in a drainage channel will not
significantly treat the pollutants in the feedlot runoff.  In the absence
of regulations, a realistic consideration is the selection of a site over
which enough control can be exerted to prevent accidental contact
of manure and waste water runoff with surface waters.
Microclimates
As discussed earlier, the site selection decisions associated with climate
are mainly those related to the type of facility and the wastes handling
method.  However, the microclimate (ambient climatic or environmental
conditions of a specific locale) of a prospective site may have some
bearing on its acceptability.   Three aspects of the microclimate of
a locale are worthy of consideration. These are extremes in wind
conditions, solar radiation, and precipitation.
Depending on major climatic conditions, wind affects the operation
of a feeding facility in many ways. Too much wind causes dusty pen
conditions in dry climates and drifting snow.  Inaccessibility and
adverse comfort indexes can lead to reduced feed conversion efficiencies
in cold climates. In a few instances too little wind can cause animal
discomfort in hot and humid  areas and may  contribute to sloppy pen
conditions in cooler areas because of decreased evaporation potentials.
Prevailing wind direction is an important factor to consider in any
locale when  predicting possible sources of  odor complaints. Additionally,
                                 17

-------
 in mountainous areas, updrafts and downdrafts should be considered
 in the prediction of possible odor complaints (Figure 3) .  Wind may
 be controlled to a certain degree by selecting a site with natural wind
 protection from vegetative shelter belts or natural land forms.  In
 the North artificial windbreaks have been successfully constructed
 along the windward side of feed pens in the absence of natural protection.
Solar radiation not only affects the productive efficiencies of animals
 but is an important factor in the efficiency of waste management and
 pollution control facilities.  The evaporation potential from a wet  manure
 surface is  determined by humidity, air movement, and solar radiation.
 Solar radiation may  be  controlled to a certain degree by  selecting
 a site with the desired  amount of shade or desired placement with
 respect to the sun's travel. Additional shade may be provided artifi-
 cially . Feedlots  located on northern or eastern slopes receive less
 intense sunlight, thus reaching maximum temperatures for shorter
 periods during the day than those located on southern or western
 slopes.  Thus, feedlot sites on northern and eastern slopes are more
 desirable in warmer climates but require more shelter for the animals
 in colder climates.  In warmer climates this location requires  less
 control of the animal's environment.  In colder climates the situation
 is reversed, and operations should be placed on  southern or western
 slopes to obtain maximum temperature benefits for animal comfort.
 In these locations proper placement may extend the northerly  range
 of wastes handling, treatment, and disposal processes which have
 minimum temperature (freezing) constraints.
 Precipitation is more important in selection of the general region than
 it is in selection  of a specific locality for location of a feedlot;  however,
 in some regions rainfall may vary considerably (as much as 10 to
 15 inches annually) over a very short distance.  Snowfall amounts
 may  also vary greatly in a short distance;  thus when locating in  northern
 climates, care should be exercised to determine snowfall amounts
 of local areas so that localities which are snowbond a portion of the
                                 18

-------
Figure 3. Relationship of Up-drafts and Down-drafts to Prevailing
             Winds in Mountainous or Hilly Areas
year may be avoided.  This point may be insignificant for most of
the country and yet unquestionably important for specific localities
which characteristically have large variance in annual precipitation.
The localized climate surrounding a feeding site does not affect the
performance of animals fed in total confinement facilities.  Accessibility
is an  important consideration of the effects of local climate on these
facilities.  Sites typified by drifting snow or dust and/or prolonged
periods of wet or damp soil conditions tend to limit waste removal
access; these should be avoided.
Soils  and Geologic Structures
Soil types and the underlying geologic structure of each  potential
feeding site should be examined to insure maximum protection from
                                19

-------
groundwater pollution. Highly permeable loose soils, shallow soils
over fractured bedrock, and shallow water tables should be avoided in
pen areas, runoff and solid manure storage pits, and field disposal
sites receiving high runoff and manure application rates.  Contamination
of groundwater is hazardous not only from the bacteriological standpoint
but also from the threat of nitrate poisoning or methemoglobinemia (an
oxygen-deprived condition in infants sometimes referred to as blue
babies) which is caused by excessive amounts of nitrates in drinking
water supplies. This malady afflicts livestock and humans (especially
small children and pregnant mothers) .
Present trends in some states are directed toward regulating the amount
of infiltration or percolation from pen surfaces and liquid wastes
impounding structures .  An example is the maximum of 0.1 acre foot
per acre per year which was recently proposed by one South Central
state.  Sites selected on heavy soils  (fine-particled, expanding, or
tight soils) with a low infiltration or seepage rate  are, in most cases,
ideal for construction of wastes retention and storage structures.
The seepage from a structure may be determined,  before use, by filling
it with unpolluted water, allowing several days to sufficiently saturate
or wet the underlying soils, and then measuring the amount of water
loss minus class A pan evaporation (lake evaporation on large structures)
Seepage tests may be run, for purposes of site selection, on smaller
scale by the use of small test ponds if a test pond bottom is at the same
soil depth desired for the full scale structure.
In the absence of suitable soil conditions, soil sealing or concrete
or asphalt liners can be included in the design of these  structures
for 300 dollars and up per acre. The advantage realized in careful
site selection is, for this reason,  of economic importance.
The depth of the water table is also important.  A shallow aquifer
is  more vulnerable to contamination and should be avoided. In areas
                                20

-------
with fluctuating shallow water tables, concrete manure storage pits
and confinement buildings designed with solid bottom manure pits may
shift from their original position and suffer damage ultimately resulting
in contamination of the aquifer.
Shallow water tables are also vulnerable to contamination when the
land is irrigated with large amounts of pollutant-rich runoff waters;
this damage is especially serious in areas of glacial till and within the
flood plains of rivers, where water tables may be only inches below
the surface and the soils are generally sandy or gravelly alluvium.
Social Considerations
Concern for environmental protection has resulted in state regula-
tions and court actions which frequently lead to great expense for
compliance.  These actions have forced many feedlots to change their
methods of operation, and a few have had to reestablish at a more suit-
able site or go out of business. Environmental controls have not only
been placed on surface and ground water pollution but have included
odor nuisances. Feedlots have had restraints placed on them solely
on the basis of odor complaints from  their neighbors.
Strong demands for increased meat production and improved meat
quality  from the general public do not offset the attendant problems
with any lessened demand for environmental improvement.  Animal
production units seldom yield any monetary benefits directly to the
complainants, who will not accept disagreeable odors around their
residences, places of work, or recreational areas. In many cases
odors may become such a nuisance to individuals that life patterns
and  established transporation routes  are changed  to avoid them.  This
circumstance is not unique to the animal feeding industry but is observed
in a great many industrial operations such as oil and gas production,
slaughter houses, chemical and plastics manufacturing, etc. All
of these industries are feeling the effects of public pressure to eliminate
nuisances created by odors,  sound,  and unsightliness.
                                21

-------
The successes of odor control efforts utilizing chemical deodorizers
and odor masking agents have, in most cases, been questionable.   In
many cases, where application of chemicals have masked odors, the
measures were temporary and the odors of some of the chemicals were
as disagreeable as the manure odors.  Perfumed aerosols have been
used with some success for short distances in Southwestern states;
however, the odors of manure are generally more persistent than the
aerosols tested and are easily detected long distances from the source.
The best odor controls are, at present, a policy of good housekeeping
coupled with proper pen design and the careful selection of the feeding
site.  Regular manure removal and disposal and very short runoff
retention times can  significantly reduce  the amount of odor produced.  A
minimum pen slope  of 2 percent enhances adequate drainage and reduces
sloppy pen conditions and resulting odors. Manure slurry storage in
oxidation ditches produces less odor than anaerobic storage pits.  In
the Northeast, anaerobic storage pits have been covered to reduce the
amount of odor.
Recent years have seen the successful advance of programs for "national
beautification."  In  short, these programs require the use of privacy
fences to conceal such unsightly places as junk yards,  dumps, freight
yards, and salvage yards from public view.   In the forseeable future
unsightliness and noise emitting from  livestock feeding operations
may bring about public initiated court actions. The selection  of a
site with vegetative shelter belts and/or land formations suitable for
visual concealment purposes or of one located a sufficient distance
from highways may prevent problems  which do not yet exist.
The selection of a site should include consideration of prevailing wind
direction, of distance from residential areas and public gathering
places,  and of the attitudes of immediate neighbors . Agreements for
free manure application and/or a steady market for neighbors' grain
or hay in return for freedom from nuisance complaints may have merit.
                                22

-------
Zoning may be used effectively in some areas to prevent the encroach-
ment of residential, shopping, and recreational areas.  A very expen-
sive but positive approach to zoning would be the purchase of enough
land to create a buffer zone between the animals and society.
The task of co-existing with society will be resolved by locating a
site which is remote from the greatest possible number of potential
complainants, by isolation through controlling as much surrounding
area as possible, and by public relations. Advertising the benefits
of feeding operations over personal discomforts may not make manure
smell  any better, but it may help make the odor more acceptable.   In
most cases, informing the public of the various pollution controls that
are being used on the facility to enhance environmental quality will
improve the image of feeding operations and animal production units.
                                 23

-------
                   PRACTICAL APPLICATION
Changes in the attitudes and interests of the people of this and many
nations over the world have aroused a much needed awareness of
our surroundings and the heritage that we are leaving behind for
future generations.  This awareness has created a need for changes
in the ways that industry and agriculture dispose of their wastes.
Early in the past decade, wastes disposal practices which were re-
commended as acceptable included locating feeding sites on steep slopes
and near streams or lakes for natural drainage and disposal of runoff
wastes in surface waters.  Recommended manure disposal practices
included filling ravines  and ditches,  from which the manure eroded
away and washed into the streams. Little concern existed for contami-
nation of ground water supplies except where obvious  damage would
occur to the water supply for the feeding facility.
A typical beef feedlot layout is depicted in Figure 4. The wastes
management design used here may have been  a recommended practice
as late as ten years ago.  The extent of environmental unbalance which
was  created by the various practices utilized in this operational plan
was  in reality unnecessary but economical. Relocation of the facility
on the same site and seven changes of minor economic  significance
(which included addition of a few wastes handling and management
facilities) could have eliminated most of the hazards to the environment.
The  same beef feedlot relocated on the same site is depicted in
Figure 5. This operation was planned with the use of the present
environment protecting concepts of site selection and wastes management.
The  pen area has been moved onto the more level land, which has  clay
soil  underlaid with a solid dolomite rather than the sandy soil and
cavernous limestone which is present on the hill slope.  The new site
is located away from the small creek and takes advantage of the vege-
tative shelter belt both as shield against cold  north winds and as a
visual screen from the road.  A ditch to divert extraneous drainage

 has been constructed around the pen area, and runoff collection ponds
 have been added all the way across the lower end of the pens.  The
 runoff from the collection ponds is pumped into a holding pond, from
 which it is distributed onto a pastured area with a large irrigation gun
 or metered onto a spray runoff treatment slope. The pens are cleaned
 regularly and the manure is temporarily stored or immediately hauled
 away and disposed of on agricultural land.
 The actual application of good site selection principles is a matter
 of common sense and the ability to apply existing state regulations.
 There are no standard numerical guidelines and mathematical formulae
 applicable to each site selection in every part of the country.  This
 report has been a compilation of the major site selection considerations
 which are representative of a large percentage of facility designs and
 most geographic locations.  Professional assistance from consulting
 engineers and/or the governmental agencies listed in the appendices
may be needed to solve unique site selection problems.
