                          EXECUTIVE SUMMARY

Environmental  regulations affect U.S.  farms  in many ways.
Traditionally/ the most  important of these regulations have been
those that restrict, and in  some cases prohibit/ the use of certain
pesticides.  Pesticides  will continue  to be  the subject of the most
important environmental  regulations for agriculture/ not only of the
traditional  registration and use regulations/ but also of new
regulations  requiring health and safety precautions for farmworkers
using pesticides/ controls on the use  of pesticides in areas with
vulnerable groundwater or near targeted estuaries/ and restrictions
on the use of  pesticides that threaten endangered species.  In
addition/, other proposed and forthcoming environmental programs
affect agriculture.  These include the banning of lead in the
gasoline used  in farm vehicles/ the control  of stormwater and other
runoff from  agricultural lands/ restrictions on agricultural
burning/ standards for the operation and repair of underground
storage tanks  containing petroleum and chemicals/ and the reporting
of toxic chemical use.

This study examined the  cumulative impact of recent and proposed
future environmental regulations on the financial condition of farms
in the United  States.  The regulations included in the analysis are
those that have been undertaken since  1982 or are anticipated to
occur by 1992/ and have  a direct impact on agriculture.  The primary
goal of the  study is not to  determine the aggregate total cost of
EPA actions  on agriculture,  but to examine the impact of these
actions on .the profitability of U.S. farms and their ability to
survive.  Because of the complexity of the agricultural sector and
'the many uncertainties that  still accompany  the new environmental
programs/ this study has had to limit its focus to a few
"representative" farm types  and has had to make many assumptions
about future environmental requirements.  Accordingly/ the study
cannot be considered to  cover all potential  agricultural impacts or
to present the final word on future environmental programs.  It
does/ however/ describe  the  kinds of impacts that may occur and
estimates the  range of potential impacts upon a group of farms that
are likely to  experience relatively large environmental costs.

For livestock.and major  field crops/ three specific farm types were
examined: (1)  an Illinois corn soybean farm/ (2) a Mississippi
cotton soybean farm/ and (3) a Kansas cattle wheat farm.  For
specialty crops/ six crops were selected; apples/ tomatoes/
potatoes/ peas/ caneberries  (e.g./ raspberries/ blackberries/ etc.)/
and peanuts.   There proved to be insufficient information to
complete the analysis for caneberries and peanuts, however, so that
results are  available only for apples/ tomatoes/ peas/ and potatoes.
The difficulty in obtaining  information about producers of specialty
crops was itself a significant finding of the study.

Three regulatory scenarios of future EPA actions were considered in
the agriculture sector study/ ranging from a conservative (low cost)
scenario to  an expansive (high cost) scenario.  In addition/ two
                                  iv

-------
 alternative levels of effects were considered for each of the farms
 that were examined.  In an average impact case it was assumed that
 the farm would incur the average environmental costs of all farms of
 that type and in a.maximum impact case it was assumed that the farm
 would incur all of the environmental costs that a farm of that type
 might face.  The maximum impact cases represent very unlikely worst
 cages,  but provide an upper bound on the potential losses under each
 regulatory scenario.

 For the three types of major field crops and livestock farms
 examined in this study/ the effects of EPA actions on farms in
 different financial conditions were considered.  The loss in income
 incurred by farms in average financial condition under the average
 impact  case (average environmental costs) was 3 percent or less
 under each of the regulatory scenarios considered.  Losses of this
 magnitude resulted in only very small changes in these farms' debt
 to asset ratios (less than 1 percent).  Under the unlikely maximum
 impact  cases/  farms in average financial condition experienced
 substantial losses in income/ but were not forced out of business as
 a result of EPA actions.

 The major field crop and livestock farms in vulnerable condition
 were more sensitive to increased environmental costs than their
 counterparts in avefage financial condition.  Although the absolute
 reduction in income was similar for farms in vulnerable and average
 financial condition under each scenario/ these losses resulted in
 much larger changes in the vulnerable farms' debt to asset ratios.
 Even though the vulnerable farms'! financial conditions were found to
 deteriorate more than the farms,in average financial condition/ only
 one of  the vulnerable farms was predicted to go out of business
 during  the forecast period (1987-1996).   The Kansas wheat cattle
 farm in vulnerable financial condition was predicted to go out of
 business even without any environmental costs and was predicted to
 go out  of business one year earlier than it otherwise would have
 under one of the regulatory scenarios considered.

 Because of limited data availability/ the study did not forecast
 losses  in income or changes in debt to asset ratios for specialty
 crop farms.  Instead/  it examined changes in net returns per acre
 (which  reflect returns to land and farmer provided labor).   Under
 the least costly regulatory scenario/ the changes were generally
 less than 1 percent for farms experiencing average environmental
 costs and less than 8 percent for even the maximally affected farm.
 Under the most costly regulatory scenario/  however/  losses of the
 average impacted producers increased substantially/  particularly for
 apple producers in New York and Michigan, where predicted losses
 were 60 percent and 84 percent respectively.  These dramatic
 decreases in net returns may bring about substantial structural
 changes in the production and market for the crops affected.  Large
 differences in the impact of EPA regulations on crops grown in
 different regions occurred because some of the proposed restrictions
.involve pesticides that are used in some regions and not in others.
 Even though the results of this study must be considered

-------
preliminary, these figures show that EPA actions could create
economic problems for .some specialty crop farms and suggest that the
Agency exercise caution in this area.

The agriculture sector study illustrates the advantages of examining
the impacts of environmental regulations at the farm level as well
as at the aggregate national level.  While national analyses provide
useful information concerning the total losses incurred by different
aggregate types of farmers (e.g., corn farmers as a whole), the
impact of environmental regulations on farms' financial conditions
depends on the distribution of those losses among farmers and on the
initial financial conditions of the affected farms.  In order to
determine the effect of EPA regulations on the ability of farms to
survive, both aggregate and farm level analyses are necessary.

This study highlights the data and analytical requirements necessary
to determine the impacts of EPA actions on agriculture.  Such
requirements include accurate pesticide usage and efficacy data/
improved national commodity price-quantity models/ and better
information on the financial and production conditions of. farmers.
Limitations in data modeling capability are currently much more
severe for specialty crops than for livestock and major field crops
and EPA is seeking improvements in this area.  The importance of
improving data and modeling capabilities is likely to increase in
the future as EPA tries to cost-effectively reduce environmental
risks associated with agriculture..

                      AGRICULTURAL SECTOR STUDY

Environmental regulations affect farms in the United States in many
ways.  Traditionally, the most important of these regulations have
been those that restrict, and in some cases prohibit/ the use of
certain pesticides.  Pesticides will continue to be the subject of
the most important environmental regulations for agriculture/ not
only of the traditional registration and use regulations, but also
of new regulations requiring health and safety precautions for farm
workers using pesticides/ controls on the use of pesticides in areas
with vulnerable groundwater or near targeted estuaries/ and
restrictions on the use of pesticides that threaten endangered
species.  In addition/ other proposed and forthcoming environmental
programs affect agriculture.  These include the banning of lead in
the gasoline used in farm vehicles/ the control of storm water and
other runoff from agricultural lands/ restrictions on agricultural
burning/ standards for the operation and repair of underground
storage tanks containing petroleum and chemicals/ and the reporting
of toxic chemical use.

This study examined the cumulative impact of recent and proposed
future environmental regulations on the financial condition of farms
in the United States.  The regulations included in the analysis are
those that have been undertaken since 1982 or are anticipated to
occur by 1992, and have a direct impact on agriculture.  The primary
goal of the study is not to determine the aggregate total cost of
U.S. Environmental Protection Agency's (EPA) actions on agriculture/
but to examine the impact of these actions on the profitability of
U.S. farms and their ability to survive. ' Because of the complexity
of the agricultural sector and the many uncertainties that still
accompany the new environmental programs/ this study has had to
limit its focus to a few "representative" farm types and has had to
make many assumptions about future environmental requirements and
other factors that may affect the financial conditions of farms/
such as farm support programs under the Food Security Act.
Accordingly/ the study cannot be considered to cover all potential
agricultural impacts or to present the final word on future
environmental programs.  It does/ however/ describe the kinds of
impacts that may occur and estimates the range of potential effects
upon a group of farms that are likely to experience relatively large
environmental costs.

AGRICULTURE AMD ENVIRONMENTAL REGULATIONS

There are a number of environmental and health hazards that may be
associated with agricultural production.   These include:

1.   Surface Water Pollution
     Water running off farm lands may carry soil particles/
     pesticides/ and animal wastes into the surface waters.

-------
 2.    Groundwater Pollution
      Pesticides and sewage sludge applied to fields  and crops/
      as well as petroleum and chemicals  from leaking
      underground storage tanks/  may seep into the groundwater.

 3.    Air Pollution
      Air pollution problems may  result from agricultural burning
      practices  and from the use  of leaded gasoline powered trucks/
      tractors and combines.

 4.    Worker Exposure
      Farm workers who handle pesticides  may be exposed to the
      harmful effects of these chemicals.

 5.    Endangered Species
      Endangered species may be exposed to the harmful  effects
      of pesticides applied to fields and crops in their
      habitat.   Another threat is a reduction in their  habitat
      caused by  agricultural expansion.

 6.    Dietary Risk
      Pesticide  residues may remain on agricultural products
      that reach the consumer.

Pesticides play  a  role  in most of these hazard pathways  and are a
critical  focus of  the environmental  regulations that affect
agriculture.  Every pesticide must be registered with EPA's Office
of Pesticide Programs  (OPP).  OPP reviews the. health/ safety/ and
environmental effects of these pesticides and/ from time to time/
issues  regulations that restrict or prohibit the use of  certain
pesticides that  are  judged  to present an unreasonable adverse
affect.   EPA also  issues regulations controlling the operation and
repair  of underground storage tanks/ and many  other agricultural
activities that may present environmental hazards.

These regulations  affect both large and small  farms in the U.S.
Restrictions on the use of  certain pesticides may  require the
substitution of more expensive pesticides and/or may reduce crop
yields.   Other environmental regulations may impose extra'operating
costs or  may require additional investments in land preparation or
farm equipment.

The ability of farms to comply with these environmental regulations
will depend not only on the costs of each regulation and the effects
of the  required activities  on agricultural yields/ but also on the
financial condition of each farm/ the market conditions at the time
the regulations become effective/ and the number of farms that are
covered.  While some environmental regulations apply to all farms/
most apply to only a portion of all farms/ such as those that use a
certain pesticide or have underground storage tanks.
Although the average net farm income in 1984 was identical to that
in 1971 — $12/000 in constant 1986 dollars — the financial
condition of U.S. farms has fluctuated dramatically over the past

-------
 two decades.   Higher prices/  expanding exports,  and low real
 interest  rates combined in the early 1970s  to produce  not  only
 record farm incomes  ($25/300  average in 1973)/ but  also a  rapid
 expansion in agricultural  production.   Unfortunately/  these trends
 all reversed in the  early  1980s.   Prices declined/  exports
 decreased/  and interest rates rose at  an unprecedented rate.
 Average net farm income fell  to a  low  of $10/200 in 1981 and did not
 surpass the $12/000  level  until 1985.   Declining incomes led to
 declining farmland values  and increasing debt-asset ratios.
 Recently/  this trend has begun to  change.   Decreased production
 expenses/  increased  government payments/  and lower  interest rates
 have allowed net incomes to rise to an average of $14/000  and have
 slowed the decline in farmland values.   The average debt-asset level
 in  1987 is expected  to show a decline  from  1986.

 Trends.for the average farm may belie  significant differences within
 farm size categories and types.  During the 1982-1985  period/  farms
 specializing in vegetables/ melons/  and other specialty crops
 enjoyed average incomes of $60/000 per year.   These farms/  however/
 account for only a small portiqn of all farms.   Farms  producing cash
 grain/  tobacco/  cattle-sheep-and-hogs/  general livestock,  and animal
 specialties all had  average incomes of less than $10/000 per year.
 These farms account  for 70% of all farms and nearly 50% of farm
 marketings.

 The financial condition of a  farm/  and hence its ability to comply
 with environmental regulations/  may vary dramatically  even within
 size categories and  types  of  farms.  For example/ a study  of the
 financial characteristics  of  U.S.  farms in  1985-1986 showed 55% of
 all commercial farms were  in  a favorable financial  situation,  while
 39% were  in a marginal situation/  and  3% were financially
 vulnerable.

 STUDY METHOD AMD LIMITATIONS

 This study consists  of an  in-depth examination of the  cumulative
 impact of environmental regulations on selected  livestock,  major
•field crop,  and specialty  crop producers.   The approach of examining
 only a limited set of producers  was chosen  because  the primary goal
 of  determining the cumulative impact of EPA actions on the financial
 condition of  producers requires  an extensive  amount of data
 collection and analysis.   The approach followed  in  this study is
 summarized as follows:

      1.   Define alternative  scenarios of EPA policies.
      2.   Select a subset  of  livestock, major field crop,  and
           specialty crop producers for analysis.
      3.   Obtain cost and  yield change information  from EPA Program
           Offices.
      4.   Estimate price changes resulting from EPA actions (under
           each scenario) for  each of the selected crops and
           livestock.
      5.   Define "impacts" for selected producers.

-------
      6.    Examine the change in the financial condition of selected
           producers under each scenario.

Definition of Policy Scenarios

Because it is difficult to predict  future EPA decisions  for many
regulations, the  study examined three alternative scenarios
corresponding to  a  range of potential policies.  The scenarios can
be summarized as  follows:

      SCENARIO  1:     Past and current EPA actions plus a conserva-
                     tive  (low cost) set of assumptions  about future
                     actions.

      SCENARIO  2:     Past and current EPA actions plus an  inter-
                     mediate  (mid cost) set of assumptions about
                     future actions.

      SCENARIO  3:     Past and current EPA actions plus an  expansive
                      (high cost) set of assumptions about  future
                     actions.

Past and current  EPA actions that were included in each  scenario
are:

      EDB - cancellation,
      Toxaphene  -  cancellation,
      Dinoseb -  cancellation/
      SARA Title III,
      Leaking Underground Storage Tanks,
      Farm Worker  Protection  Standards,
      Chlorodimeform - cancellation  of yield enhancement,
      Alachlor  - restricted use.

The scenarios also  include alternative assumptions (high, mid, and
low cost)  about EPA actions in the  following areas:

      Fungicides
      Corn Rootworm  Insecticides
      Broad Spectrum Organophosphates
      Grain Fumigants
      Pesticides in  Groundwater Strategy
      Lead in Gasoline Phaseout

Detailed information concerning the assumptions about future
policies made under each scenario are provided in Appendix A.  The
scenarios in this study include only direct impacts of federal EPA
actions.  Indirect  impacts, such as effluent regulations on
pesticide manufacturers, may result in increased costs to farmers,
however, it was beyond the scope of this study to determine the
extent to which higher production costs incurred by agricultural
input industries would be passed on to farmers in the form of higher
input costs.   Environmental protection actions which may be taken at

-------
the state level are also not: considered in this study.  Finally,
this study does not account for voluntary actions taken by farmers
(e.g., voluntarily ceasing to use a pesticide prior to
cancellation).

Crop and Livestock Selection

A crucial step in this study was determining which producers to
focus on.  An effort was made to include those producers who were
likely to experience relatively large impacts under the alternative
policy scenarios considered.  The cases that are examined,
therefore, provide a variety of impact levels, but include worst
case examples.  The selection of livestock and major field crop
producers was enhanced by the availability of an econometric
simulation model, AGSIM, that indicated which crops and livestock
were likely to be most affected.  For livestock and major field
crops, three specific producer categories were examined.  Since the
ability of any given type of producer to survive cost and yield
affects associated with EPA actions is a'function of his initial
financial condition, two alternative financial conditions were
examined for each of the livestock and major field crop producers
considered:

     *     the average  financial condition  of all producers  of the
           commodity and region  considered,  e.g.,  the average of all
           Illinois  corn soybean farmers, and

     *     the average  financial condition  of all producers  of the
           commodity and region  considered  that  are  in a "vul-
           nerable"  financial  position.  Vulnerable  producers are
           defined as those  that have  debt  to asset  ratios greater
           than 0.4  and have a negative  net cash income.

This resulted in the examination of six different representative
livestock and major field crop farms:

     * Illinois Corn Soybean Farm
           -  in average.financial condition
           -  in vulnerable financial condition

     * Mississippi Cotton Soybean Farm
           -  in average financial condition
           -  in vulnerable financial condition

     * Kansas Cattle Wheat Farm
           -  in average financial condition
           -  in vulnerable financial condition
The selection of specialty crops was more difficult than the
selection of livestock and major field crop producers since
specialty crop production is more diverse and information on
pesticide usage is much more limited than for major field crops. In
addition, no information was available on the initial financial

-------
condition of specialty crop producers.  Through discussions with
staff at EPA'3 Office of Pesticide Programs, the following set of
specialty crops was selected:

      *  apples,
      *  tomatoes  (fresh and processing treated  separately),
      *  peas/
      *  potatoes,
      *  peanuts/  and
      *  caneberries.

Analyses were not completed on peanuts and caneberries due to data
acquisition problems.

Obtaining Crop and Yield Effects

The EPA Program Offices provided information on the cost and yield
effects  (by crop and by region) that were expected to result from
each individual action considered.  In addition/ they estimated the
percent of farms of a particular type and region that were expected
to incur each of the effects.

Estimation of Price Changes

EPA actions may increase fixed and variable costs/ decrease yields/
and affect production decisions.  These impacts may in turn be
translated into commodity price changes.   Failure to account for
these price changes would result in overestimation of the impact of
EPA actions on farmers who bear the initial cost of EPA policies and
would overlook the potential gain to producers who are not directly
affected by EPA actions.

In order to estimate the price changes that might occur due to the
impact of EPA actions on livestock and major field crop producers/ a
regional econometric-simulation model/ AGSIM, was utilized.  AGSIM
includes eight major field crops and five types of livestock.  The
effects of EPA policies are entered into AGSIM as per-acre cost and
yield changes for each crop in each of ten United States Department
of Agriculture (USDA) production regions.  A more detailed
description of AGSIM is provided in Appendix B of this report.

A national price-quantity model developed by Erik Lichtenberg/
Douglas Parker and David Zilberman was utilized to estimate price
changes due to the impact of EPA actions on specialty crop
producers.  This model is much more limited than AGSIM.  It does not
account for variation in impacts among different regions (only one
national production cost change is used/  which represents a weighted
average of individual regional impacts).   It also does not account
for impacts on substitute crops that are not affected directly
(e.g./ a regulation that increases the price of broccoli may in turn
increase the demand for,  and price of/ cauliflower).   A more
detailed description of the national price-quantity model used for
specialty crops is provided in Appendix C.

-------
Defining "Impacts" for Selected Producers

Since we are simultaneously examining the effect of several EPA
policies, a fundamental issue to be determined, was:  how is an
"impacted" farmer defined?  For example, an Illinois corn soybean
farmer may be affected by the cancellation of several different
pesticides, may incur insurance costs if he has an underground
storage tank that meets certain criteria, and may incur an expense
to rebuild his leaded gasoline tractor engine if all lead is banned
from gasoline.  How many of these potential costs do we assume the
"impacted" farmer incurs?  For each producer, two alternative sets
of financial impacts were examined:

       *   Maximum Impact  Case;   This  case  assumes  that  the producer
           is  impacted by  every  regulation  that  may possibly  affect
           a producer  of that  type.

       *   Average Impact  Case;   This  case  assumes  that  the producer
           experiences the average  impact of  producers of  that
           type  -  e.g., if 10  percent  of all  producers of  a given
           type  (such  as Illinois corn producers) experienced a  cost
           of  $1000, we would  utilize  a  $100  cost  ($1000 x 0.1)  for
           the average impact  case.

Estimation of Financial Effects on Selected Producers

In order to examine.the effect of EPA policies on the selected
producers of major field crops and livestock, a whole farm recursive
programming simulation model of representative producers,  REPFARM,
was used (see Appendix D for a description of REPFARM).   A REPFARM
model for each of the selected producers was developed by USDA.   The
REPFARM models were simulated over the 1987-1996 period, using the
average and maximum cost and yield impacts for each policy scenario
and the scenario specific prices derived from A6SIM.  The effect of
EPA policies on each of the representative farms'  financial
condition was determined by examining:

     * the change in net cash farm income I/, and
     * the change in debt to asset ratio.

This examination provides  information on the effect of EPA actions
on the producers'  income and ability to survive.  It is  assumed that
a farm goes out of business when its debt to asset  ratio reaches one
— i^e.,  its level of debt is equal to its  assets.
I/   Net cash farm income is defined as cash farm income minus farm
     expenses.  It includes both property tax payments and income
     from government programs.  It does not include depreciation of
     machinery and buildings or off-farm income.

-------
 There  is only  limited  information on the baseline  financial
 conditions of  specialty crop producers.  Therefore, our ability to
 determine the  impact of EPA actions on their  financial condition  is
 more limited than  for  livestock and major field crop producers.   The
 impact of EPA  actions  on  specialty crop producers  was estimated by
 examining the  change in net returns per acre  for producers in
 different production regions.  Net returns/ for the purposes of this
 report/ consist of all farm income minus all  farm  expenses/ with  the
 exception of non-hired labor and land/ on a per acre basis.  Net
 returns per acre/  therefore/ reflect the return to land and farmer
 provided labor.

 Budget information was collected for each of  the selected specialty
 crop producers in  several different production regions to establish
 a baseline level of net returns.  The specialty crop budgets for
 each region were then  projected over the 1987-1996 period using the
 average and maximum impacts for each region under  each policy
 scenario along with the scenario specific prices (determined by the
 national price-quantity model).  This projection provides
 information on the change in net returns per  acre  for producers in
 different regions  under each policy scenario  (see  Appendix E).

 Study Limitations

 The complexity of  the  agricultural sector/ the uncertainty
 associated with many environmental regulations/ and data and
 modeling limitations necessitated the use of  many  simplifying
 assumptions.  Each of  the study's major limitations is discussed  in
 more detail below.

 Examination of a Limited Number of Commodities

 As discussed above/ data and analytical requirements associated with
 the objectives of  this study necessitated choosing a limited set  of
 commodities to examine.  Producers of crops not considered in this
 report will experience different levels of impacts; however/  an
 effort was made to include producers that are expected to experience
 relatively large impacts.

 Limited Information About Producer Baseline Conditions

 In addition to EPA actions that will affect different crops to
 varying degrees/  producers of the same crop will also be affected to
 varying degrees depending on their:   (I)  geographic location (e.g./
 different regions use different pesticides)  and (2) baseline
 production and financial characteristics.   Marginal producers may be
 forced out of production/ while producers in more  favorable
 financial condition will be able to withstand greater impacts.
 Information on the initial financial condition of the representative
 livestock and major field crop producers was  available.   However/
 numerous assumptions about future prices/  government policies/
 interest rates/ and cost and yield trends affect the baseline
projections (predicted under the assumption of no EPA policy

-------
 impacts)  of net cash farm income and debt  to asset  ratios obtained
 from the  REPFARM models.   If these assumptions result  in an
 overestimate of the financial strength of  the representative farms
 in the baseline/  then we'will overestimate the ability of producers
 to survive in the face of EPA actions.  Likewise,  if these
 assumptions result in an  underestimate of  the financial strength of
 the farms, then we will underestimate the  ability  of producers to
 bear the  costs of EPA actions.   More information about the specific
 assumptions used in the REPFARM model is supplied  in Appendix D.

 Sensitivity analysis reveals that assumptions about crop yields and
 future crop prices have a large effect on  the REPFARM  model results.
 For example/  upper and lower sensitivity runs were  made assuming
 that prices were 15% higher and lower respectively  in  the years
 1991-1996.  The resultant estimates of net cash farm income in the
 upper sensitivity runs were double those in the lower  sensitivity
 runs.   This analysis illustrates the sensitivity of the results of
 this study to critical assumptions/  and helps to place the magnitude
 of the predicted effects  in perspective relative to the other
 factors that influence farms'  financial health.

 Only limited information  was available on  the baseline financial
 conditions of specialty crop producers. Crop enterprise budgets for
 the selected specialty crops were collected from the Agricultural
 Extension Service in major producing states/ which  provided
 information necessary to  calculate the net returns  per acre for each
 crop/region examined.   However/  information on the  debt to asset
'ratios of specialty crop  farmers,  or their total net farm income was
 unavailable.   The limited information;on baseline  financial
 'conditions makes it difficult to determine whether  the EPA actions
 assumed in alternative scenarios would actually cause  the specialty
 crop producers examined in this study to go out of  business.

 Uncertainty about Future  EPA/  and other Government  Agency Actions

 In order  to complete this study/  it was necessary to make
 assumptions about what actions EPA might take in the next five
 years. There is obviously a tremendous amount of uncertainty about
 which actions will be undertaken in the future.' This  study does not
 presume to accurately predict future actions of the Agency.  Rather,
 it attempts to define a range of impacts that correspond to a
 plausible range of future policy scenarios.

 In addition/  this study does not account for possible  indirect
 impacts on agricultural producers (through regulation  of
 agricultural input industries)  and does not account for actions
 taken at  the state level.   To the extent that state actions further
 increase  production costs or decrease yields/  failure  to account for
 these actions results in  an underestimate  of the direct effects on
 farms due to environmental and health concerns. State actions may
 be especially significant for the livestock industry,  which is a
 major source of nonpoint  source (NFS)  pollution.  Under legislation
 passed in February,  1987,  states were given grants  to  assess the

-------
magnitude of the NFS problem and to develop management plans/ which
are due at EPA by August 1988.  State actions in the NFS area/
however/ are not accounted for in this analysis.  This omission may
be particularly significant, for the.KS wheat cattle farm.

Another potential bias created by not modeling state level actions
occurs in.the Pesticide in Groundwater Strategy.  In this analysis/
federal Pesticide in Groundwater Strategy actions were assumed.  In
reality, states may take action on their own, circumventing federal
level action.  If state actions are less severe than the federal
level actions assumed in this analysis, then these results may tend
to overestimate the magnitude of the Pesticides in Ground-water
Strategy.

Finally, this study does not account for possible changes in USDA
policies in response to income losses generated by EPA actions.
Agricultural programs may tend to cushion the effects of EPA
regulations.  For example, crop insurance would protect farmers from
the losses caused by removal of important pesticides during periods
of infestation.

Uncertainty About the Incidence and Magnitude of EPA Impacts

Once a policy scenario is defined/ predicting which producers will
be impacted requires an extensive amount of information.  For
example, if a particular pesticide is to be canceled, detailed usage
data is required to predict which producers Will be affected.
Pesticide usage data for major field crops are available at state
and multi-state production region levels (based on statistically
valid samples collected by USDA and other sources).  However/ these
data are not reliable at a county level.  This created problems in
predicting the impacts of the Pesticides in Groundwater Strategy/
since this program was assumed to result in county specific
pesticide cancellations.  Data provided by a contractor were used to
determine the incidence of Pesticides in Groundwater actions.
However/ this data base is composed of information drawn from
available reports and expert opinions of local Cooperative Extension
Service personnel and is not based, on a statistically valid sample.

Predicting the incidence of EPA actions on specialty crops is
especially difficult because there is less information about
pesticide usage on these crops than on major field crops.  Much of
the specialty crop pesticide usage data utilized in this analysis
were derived from private data collection agencies (e.g., Doanes)
that do not provide information on the sampling techniques utilized
in collection.  The lack of reliable pesticide usage information for
specialty crops severely limits the reliability of conclusions drawn
in this study.  A more detailed discussion of the data and
assumptions used in this analysis is provided in Appendix F.

In addition to knowing what types of producers are likely to be
affected by each EPA action/  it is important to determine the extent
of the impact.  For a pesticide cancellation/ this requires knowing


                                 10

-------
what  alternative will be used  in place of the cancelled pesticide
and what cost  and/or yield variations the user will experience with
this  alternative.   These efficacy data are not always readily
available/  and are  based primarily on expert judgement rather than
on  models of farmers' responses to regulations and the resulting
crop  and yield effects.  The lack of reliable efficacy data
increases the  uncertainty associated with predicting impacts of EPA
actions.  Furthermore/ there was not sufficient information to fully
account for changes in quality (e.g./ size/ shape) brought about by
restrictions of pesticides.

Finally/ effects of pesticide  cancellations were projected to
dissipate evenly over a seven  year period as users adjust their
practices and  new pest control products become available.  The use
of  an arbitrary assumption of  this type was necessitated by the lack
of  a  reliable  method to predict the development of substitute pest
control products and the adjustment in agricultural practices over
time.  Clearly this assumption may overestimate the adjustment
process for some cancellations and underestimate it for others.
Some  commodities/ such as apples and oranges/ are less able to
adjust to pesticide cancellations through the use of more pest
resistant species due to the long term structure adjustment problem
associated  with tree removal and replacement.

Model Assumptions

In  addition to assumptions about the incidence and magnitude of
'impacts/ the models themselves utilize assumptions that affect the
results.  For  example/ the assumptions about elasticities of supply
and demand  that are used in the national price-quantity models are
crucial in  determining the extent to which EPA impacts are passed on
to  consumers in the form of higher prices.  Elasticities are often
listed as a range of numbers and are for a wide category of crops
rather for  a specific crop.


RESULTS OF  LIVESTOCK AMD MAJOR FIELD CROP IMPACT ANALYSES

As  previously  discussed/ the change in the financial condition of
selected livestock  and major field crop producers was examined using
USDA's REPFARM model.  Changes in financial condition are measured
by  changes  in  net cash farm income and changes in debt to asset
ratios that are caused by EPA  actions under each of the three
scenarios.  Assumptions about  initial characteristics of the
representative  producers along with the cost and yield effects
assumed for each EPA action are presented in Appendix D.

All of the  different farm types and level of impacts that were
considered  in  our analysis resulted in 36 sets of output;
therefore/  all  the  results are not presented in this report.  Only
the results of  Scenarios 1 and 3 for the farms in average financial
condition are presented here.  These results provide a range a
impacts that are predicted for the case study farms in average

-------
financial condition.  A brief discussion  is provided  as to  how  the
results for the farms in vulnerable  financial condition differ  from
those in average financial condition.   In viewing these results it
should be recognized that many  factors  influence the  financial
condition of a farm.  Accordingly/ the  actual impact  that the EPA
policies considered in this study would have on any particular  farm
may differ from the results presented here.

Illinois Corn Soybean Farm

There are 30/837 farms in Illinois that are classified as cash  grain
farms that produce corn and soybeans.   Survey observations  of these
farms were used to develop the  baseline characteristics of  the
Illinois corn soybean REPFARM in average  financial condition  (See
Appendix D for a description of baseline  characteristics of each
REPFARM model).  There are 112/489 farms  in the five  state  Cornbelt
region (Iowa/ Illinois/ Indiana, Missouri/ Ohio) that fit the corn
soybean farm definition.

Illinois Corn Soybean Farm in Average Financial Condition

SCENARIO 1

Figures 1-a and 1-b indicate the net cash farm income and debt  to
asset ratios/ respectively/ of  the representative Illinois  corn
soybean farmer (average financial condition) under Scenario 1.  The
maximum impact case (which.assumes the  producer incurs, all  possible
cost and yield impacts) results in a mean annual decrease in net
cash farm income of $2/900.  This represents an eight percent
average annual decrease from the baseline.  The mean decrease under
the average impact case (which  assumes  the producer experiences the
average costs and yield impacts of all  similar producers)/  however/
is significantly less at $270,  or less  than one percent of  the
baseline net cash farm income.  The substantial gap between the
average and maximum impact cases is due primarily to the underground
storage tank regulation.  The costs associated with this regulation
are substantial/  yet only a small percentage of farmers are
affected. 2/

A reduction in net cash farm income due to EPA policies may result
in increases in farmers' debt to asset  ratios in two ways:  (1) it
decreases the return to land and/ therefore, the value of land
(which is the primary component of farm assets)  and (2) it  may cause
farmers to borrow funds if they are put into a position of  negative
21   Farmers having a petroleum underground storage tank  (>1100
     gallons) were assumed to incur  $2500/yr.  insurance cost  (1988-
     1996) and a $500 charge in 1991 and  1994  for  a tank  tightness
     test.  No costs were included for remedial action and  it was
     not assumed that any farmers would remove their USTs.

 cash  flow.  The debt to  asset  ratio  in  each REPFARM model may be
 viewed as an  indicator of the  producer's ability to survive.
 Producers are assumed to go out of business when their debt to  asset
 ratio equals  one.  As seen in  Figure 1-b, the maximum impact case
 results  in a  very slight increase in debt to asset ratios under
 Scenario 1  (one percent) while no significant change in the debt to
 asset ratios  occurred for the  average impact case.

 SCENARIO 3

 Under the expansive set  of EPA actions  (Scenario 3) the maximum
 impact case results in an average annual decrease in net cash farm
 income of $9,200  (Figure 2-a)  and an average annual increase in
 debts to assets of two percent (Figure  2-b).  These substantial
 impacts  are due primarily to assumptions about restrictions on  the
 use of alachlor, triazines and corn  rootworm insecticides.  The
 average  impact case, however,  results in an increase in average
 annual net cash farm income.   This occurs because the larger cost
 and yield changes incurred by  affected  corn and soybean farmers
 under Scenario 3 reduced production  levels and raised corn and
 soybean  prices.  These higher  prices more than offset the cost  and
 yield impacts assumed in the average impact case.  The average
 annual increase in net cash farm income for the average impact  case
 is $4,800 <14 percent increase from  the baseline).  This results in
 a slight improvement in  the debt to  asset ratio.

 The large difference between the results in the average and maximum
 impact"cases highlights  the' importance of understanding the
distributional implications of EPA policies.  Because initial price
 and yield impacts are not distributed evenly among farms, producers
will experience different financial  impacts.  In cases where EPA
actions  result in commodity price increases, farmers who experience
relatively small crop and yield effects may actually benefit from
the policies.  In order  to provide more insight into the
distribution of cost and yield impacts expected under alternative
scenarios,  a cumulative  probability  cost curve was generated for
each of  the representative producer  in average financial condition
under each scenario.  These curves indicate the probability that
each representative farm will  incur  a cost less than or equal to a
given level.  (See Appendix G  for a  complete description of these
curves).   The discounted present value of the cost and yield impacts
 (1987-1996)  incurred under the maximum impact case in Scenario  3 is
over $60,000.  However,  Figure 3-b indicates that under Scenario 3
the representative Illinois corn soybean farm in average financial
position has a .7 probability  of incurring discounted present cost
and yield impacts (1987-1996)   that are less than $23,000; and a .5
probability of incurring impacts of  less than $5,000.   The
cumulative probability cost curves illustrate that the maximum
impact cases described here represent a set of very unlikely worst
cases.   The average impact cases presented in this section provide
insights  into the financial effects that each of the representative
farms examined would have a significant chance of incurring.   As
indicated in Figure 3-b,  under Scenario 3 the representative

 Illinois Corn Soybean Farm in Vulnerable Financial Condition

 Results for the Illinois corn soybean farm in vulnerable  financial
 condition are presented in Appendix D and are only summarized
 briefly here.   Of the 30,837 Illinois corn soybean farms,
 approximately ten percent were determined to be in vulnerable
 financial condition.   Survey observations on this  group of farms
 were used to  develop the characteristics of the Illinois  corn soy-
 bean farm in  vulnerable financial condition.

 The absolute  decrease in net cash farm income for  the vulnerable
 farm under each scenario is approximately the same as the decrease
 experienced by the farm in average financial.condition, however,  the
 percentage reduction is greater because the base income level of the
 vulnerable farm is much less than that of the average farm (an
 annual average of $550 as opposed to $35,000).   Likewise,  the change
 in  net cash farm income experienced by the vulnerable farm has a
 greater impact on its debt to asset ratio (e.g., the  changes in debt
 to  asset ratios for the maximum impact case under  Scenario 3 are two
 percent and 22 percent for the Illinois farms in average  and
 vulnerable financial condition,  respectively).   This  result occurs
 because the lower base income of the vulnerable farm  makes it more
^sensitive to  changes in cash flow than its counterpart in average
 financial condition.

 The difference in results observed for the vulnerable and average
 farm highlights the importance of understanding the baseline
 financial condition of farms when predicting how EPA  actions will
 affect their  ability to survive.   Although EPA actions result in
 much greater  changes in debt to asset ratios  for the  vulnerable farm
 than for the  farm in average financial condition,  the vulnerable
 farm is not predicted to go out  of business,  even  under the most
 expansive sets of EPA actions.

 Mississippi Cotton Soybean Farm Results

 There are 1,798 farms in Mississippi that are classified  as field
 crop farms  producing cotton and soybeans.   Survey  observations on
 these farms were used to develop the Mississippi cotton soybean
 REPFARM in  average financial condition.   There  are 3,576  farms in
 the three state Delta region (Mississippi,  Arkansas,  Louisiana)' that
 fit the cotton soybean farm definition.
                                  17

Mississippi Cotton  Soybean Farm  in Average Financial  Condition

SCENARIO  1

The maximum impact  case  for the  Mississippi  cotton  soybean  farm in
average financial condition results  in  a mean  annual  decrease  in net
cash farm income of $10,700 under Scenario 1 (Figure  4-a).   The mean
decrease  in net cash farm income under  Scenario  1 for the average
impact case/ however,  is significantly  less  at $1,700.   The gap
between the average and  maximum  impact  cases occurs because
underground storage tank regulations, and dinoseb and toxaphene
cancellations cause significant  costs to impacted producers, but
only affect a small fraction of  producers. 3/  For example,  only 1.2
percent of the soybean acres in  Mississippi  are  thought  to  be
affected  by the cancellation of  toxaphene and  less than  two percent
of the farms are expected to have underground  storage tanks.

Both the  maximum and average impacted producers  experience  increases
in their  debt to asset ratios under  Scenario 1 (six percent and .6
percent increases/  respectively), yet neither  producer is forced out
of business (Figure 4-b).

The discounted present value of  the  cost and yield impacts  (1987-
1996) incurred under the maximum impact case in  Scenario 1  is  over
$80,000.  However,  the cumulative probability  cost curve for the
Mississippi cotton  soybean farm  in average financial  condition
(Figure 5-a) indicates that it has a 70 percent  chance of incurring
discounted present  cost and yield impacts (1987-1996) that  are less
than $10,000.  The  maximum impact cases described here,  therefore,
should be viewed as  a set of very unlikely worst cases.  The average
impact case for Scenario 1 corresponds to a  level of  discounted
present costs and yield effects  that the representative  Mississippi
cotton soybean farm has a 25 percent chance  of exceeding, and  a 75
percent chance of having lesser  impacts.

SCENARIO  3

Under Scenario 3, the maximum impact case results in  an  average
annual decrease in  net cash farm income of $14,200  (Figure  6-a)  and
an average annual increase in debts  to assets  of six  percent (Figure
6-b).  The loss in  income is greater than that experienced  under  the
maximum impact case  for Scenario 1.  The loss  in income  for the
average impact case,  however,  is less under  Scenario  3 than under
Scenario  1 ($400 less, on average).  This result occurs  because the
larger cost and yield changes incurred by cotton and  soybean farmers
as a whole under Scenario 3 reduce production  and cause  higher
cotton and soybean prices.   These higher prices cause the income  of
3/   See Appendix D, Table D-6 for the cost and yield  impacts  and
     percent of acres treated assumed for the cancellation  of
     dinoseb and toxaphene.  Information about UST assumptions may
     be found in both Appendix D and Footnote 1.

those farmers who incur only the mean cost and yield impacts to
actually increase above the baseline in the. years 1994-1996.  As
indicated in Figure 5-b, the average impact case corresponds to a
level of cost and yield effects, that the representative .farmer has
approximately a 40 percent chance of exceeding and a 60 percent
chance of having lesser impacts.

Mississippi Cotton Soybean Farm in Vulnerable Financial Condition

The results of the Mississippi cotton soybean farm in vulnerable
financial condition are presented in Appendix D and are summarized
only briefly here.  Of the 1,798 MS cotton soybean farms
approximately 14 percent were determined to be in vulnerable
financial condition and survey observations .relating to this group
of farms were used to develop the characteristics of the Mississippi
cotton soybean farm in vulnerable financial position.
The reduction in net cash farm income experienced by the vulnerable
Mississippi cotton soybean farm in each scenario is slightly greater
than that experienced by the Mississippi cotton soybean farm in
average financial condition — e.g., for the average impact case
under Scenario 1, the vulnerable farm has an average annual loss of
income of $2,500, as opposed to the $1,700, loss experienced by the
farm in average financial condition..  This result occurs because the
vulnerable farm has more cotton and soybean acres than the farm in
average financial condition and,  therefore, experiences greater
total cost and yield effects.  The larger cost and yield effects and
a lower base income level for the vulnerable farm combine to result
in larger changes in its financial condition than those experienced
by the farm in average financial condition under each scenario.  For
example, under the average impact case for Scenario 3, the debt to
asset ratio increases by over three percent for the.vulnerable farm
and by 0.5 percent for the farm in average financial condition.

Kansas Wheat Cattle Farm Results

There are 19,966 farms in Kansas that produce wheat and cattle.
Survey observations of these farms were used to develop the Kansas
wheat cattle REPFARM in average financial condition.    There are
50,143 farms in the four state Northern Plains region (Kansas,
Nebraska, North Dakota, South Dakota)  that fit the wheat cattle farm
definition.

Kansas Wheat Cattle Farm in Average Financial Condition

SCENARIO 1

The maximum impact case results in a mean annual decrease in net
cash farm income of $2,800 under Scenario 1 (Figure 7-a).  The mean
decrease in net cash farm income for the average impact case,
however, is only $380.  The substantial difference between the
average and maximum impact cases is due primarily to the underground
storage tank regulations which are expected to impact only two

percent of producers in the Northern Plains region. 4/ The
representative Kansas wheat cattle farmer has a  .65 probability of
incurring cost and yield impacts that are less than those assumed in
the average impact case  (Figure 8-a).  These cost and yield impacts
are less than one-eighth of those assumed in the maximum impact
case.

Under the average impact case, the producer experiences a slight
(less than one percent) increase in his debt to asset ratio.  The
mean annual increase of debts to assets under the maximum impact
case is three percent  (Figure 7-b).

SCENARIO 3

Under Scenario 3, the maximum impact case results in an average
annual decrease in net cash farm income of $9,700 (Figure 9-a) and
an average annual increase in debts to assets of 22 percent  (Figure
9-b).  The reduction in income and increase in debt to assets under
the maximum impact case for Scenario 3 is large enough to cause the
Kansas wheat cattle farm to enter into the vulnerable farm
definition by the end of the forecast period.  This is the only case
in which this result occurs.

The: average impact case, however, results in an average annual
increase in net cash farm income of '$310.  As with the Illinois corn
soybean farm, this result occurs because the commodities produced
(the representative Kansas wheat cattle farmer produces corn,
soybeans, and sorghum as well as wheat and cattle) incur larger cost
and yield changes under Scenario 3.  These higher costs are passed
on to consumers in the form of higher prices, causing the net cash
farm income of those farmers who incur only the mean cost and yield
impacts to actually increase above the baseline.

As illustrated in Figure 8-b,'the representative Kansas wheat cattle
producer has a .60 probability of incurring cost and yield impacts
that are less than those corresponding to the average;impact case
for Scenario 3.  It should be noted, however, that the discounted
present costs presented in Figure 8 do not include the additional
expense that the wheat cattle farmer would incur if EPA actions;
result in higher feed costs.  These higher costs have been accounted
for, however, in the REPFARM model.

.seven percent • were^ determined to be  in  vulnerable  financial
condition;   Survey observations relating to  this group pf farms were
used to develop the characteristics  of  the Kansas  wheat cattle farm
in vulnerable financial  condition.

In the baseline .(no EPA  actions) the vulnerable Kansas wheat cattle
farm goes out of business  in  1993.   The decline in net cash farm,
income experienced by the  vulnerable farm under the maximum impact
case for-'""Scenario  1 causes it to go  out of business one year earlier
than in the  baseline.  The farm does not go  out of business earlier
than 1993 under any of the other scenarios.

RESULTS OF SPECIALTY CROPS IMPACT ANALYSES

The impact of .EPA  actions  on  specialty  crop  producers  was estimated
in a two-step process/ similar to that  used  -for livestock and major
field'crops.. First, commodity price changes resulting from, EPA
actions were predicted.  Next, the new  set of commodity prices,
along with the initial cost and yield impacts were used to determine
the impacts  of EPA actions on the net returns per  acre (returns to
land and farmer; provided labor) of, selected  producers  via income
budgeting analyses.

Results of average and maximum impact cases  for four of the
specialty crops under consideration  for Scenarios  1 and 3•are
presented^ below along with? a  :brief introduction of 'this .crop;.,
Results of the inc.ome ^budgeting analyses for all scenarips are
contaihe'd in Appendix E-  along; with: the  initial .cost and yield impact,
estimates.

As this study developed, data deficiencies forced  the  exclusion of
caneberries  and peanuts  from  the analysis.   Data which were
available are presented  in Appendix  E along  with those of other
specialty crops.


Applas

Apple production in the  UvSl  has approximately dbubled;since the
19,4'Osv-• The  trend  in cuJLtivars has b£en toward /higher  -quality;
dessert apples.  Current cultivars of major  importance, are Red .
Delicious (39 percent),  Golden -Delicious- (17 percent), Mclritosh (7
percent), Rome (6  percent), Granny Smith (6  percent),  Jonathan (A
percent) and York  (4 percent).

Apples are grown widely  throughput'the  U.S.,  with  commercial
production in about 35 states.  However,  the-principal states (and
their approximate  share  of total U.S. production)  are  Washington (36
percent), New York (12 percent) and  Michigan (10 percent).
Harvested acreage  in these states is ^approximately 161,000,  62,000
and 68,000 acres respectively.  According to ,1982  estimates,
Washington, has the largest number of farms with approximately 5,400,
followed by  Michigan with  2/800 and  New York with  2,000.  .
                                  27

-------
 In recent years  apple production  has  been  most  profitable in the
 Washington growing  areas.where  slightly higher  yields and higher
 valued production more  than  offset  higher  per. acre production costs.
 Returns have been more  modest in  New  York  and Michigan growing
 areas.

 SCENARIO 1

 Apple producers  in  all  three study  regions (Washington,  New York,
 Michigan) experience similar decreases  in  net returns per acre under
 Scenario 1 -- from  $2..30 to  $6.60 per acre — but these decreases
 are higher on a  percentage basis'  .in. Michigan, .because, of the state's
 lower2average returns-per-acre  (Figure  10).   Decreases;in: net
 returns under Scenario  1 .are caused by  farm worker safety
 restrictions arid restrictions on  the  use of prganbphosphates.,

 SCENARIO 3

 Changes in net returns  per acre for the average impact. ;case under
 Scenario 3.differ substantially among production regions (Figure
 il).  Net returns increased  18  percent  in  Washington in 1990 while
 during the same  year net returns  in New York and Michigan decreased
 134 i percent and  214 :perceht  respectively,.   Such dramatic decreases
 in net returns, may  bring about- substantial structural changes, the
 discussion of: which is  beyond the sccipe of this study. ' The .large
 differeritiai in  net returns  among different regions is due to
"proposed restrictions on the.use  of fungicides  in 1990.   These
 restrictions would- substantially  affect New York and Michigan apple
 production  (e.g., 17 and 12  percent • yield  reductions)  but have no
 production effect in Washington.  5/ ; The rise in Washington
 producers', net .returns  is.due to  the. i. 8 .percent increase in price
 above the base year.caused by the national decline in apple supply.


 Potatoes

 Potatoes are groWn;  commercially in  nearly  every state.  Total U.S.
 production ranges :ftorn .16 to 20 million; tons, • depending on the year.
 Of this production:, approximately one-third is  used for. table stock
 and one-half for processing. The remainder is  used for seed,
 livestock feed,  and export.

 While potatoes :are  grown throughout the U.S., production is .
 concentrated in  several areas.  The most important area is Southern
 Idahp, which typically  accounts for'about  25 percent ..of total
 production-.  Southr-central Washington is the second largest
5/    The fungicide restrictions considered :under Scenario 3 are the

production area, followed by the Red River Valley of North Dakota
and Minnesota, and northern Maine.  Together these regions account
for up to 60 percent of total U.S. production, with Washington-Idaho
harvesting approximately 437,000 acres, North Dakota-Minnesota
194,000 acres, and Maine 98,000 acres.  According to 1982 estimates
of potato farm numbers, Washington-Idaho has approximately 2,400,
followed by North Dakota-Minnesota with 1,400 and Maine with 1,100.

Cultural practices vary among the major production regions.  In
Idaho and Washington most of the potato acreage is irrigated and
crop yields are among the highest in the country.  Acreage in the
Red River Valley and Northern Maine is primarily dryland with
appreciably lower yields and more modest contributions to farm
income from an acre of production.

SCENARIO 1

Net returns per acre in 1987 for the average impact case are
slightly lower than the baseline in all regions due to effects of
the 1984 cancellation of EDB and the 1987 suspension of dinoseb
(Figure 12).  In 1990 net returns for Washington-Idaho producers
increase above the baseline by .2 percent (average impact case)
while net returns for the other regions also increase, but still
remain below the baseline.  This is explained by the simultaneous
increase in the national price (.26 percent above the baseline) and
proposed 1990 groundwater regulations which do not affect the
Washington-Idaho producers.

In all three production regions the decrease in net returns is
substantially larger in the maximum impact case than in the average
impact case.  Average annual net returns (1987-1996) decreased by .7
percent in Washington-Idaho, four percent in Minnesota-North Dakota,
and 8 percent in Maine under the maximum impact case.  Maximum
impact estimates are considerably larger than the average for such
regulations as the dinoseb cancellation in 1987 and the groundwater
regulations in 1990 'because only a small percentage of producers are
affected.

SCENARIO 3

Results of regulatory impacts on potato producers' net returns per
acre are dominated in this scenario by the 1990 proposed restric-
tions on organophosphate use (Figure 13).   Average impact estimates
in 1990 include 6.4 and 7.0 percent yield declines in  Minnesota-
North Dakota and Maine respectively, while the yield decline in
Washington-Idaho was estimated at .96 percent (less organophosphates
are used in this area).  Such a large decline in production results
in price increases of 1.8 percent above the base year of 1987 to its
highest level during the study period.  In Washington-Idaho this
increase in price was able to offset the relatively small decline in
yield and net returns actually increased above the baseline for the
                                 31

average impact case.   In the other regions/ the commodity price
increase was modest in relation to the crop yield decreases/ and net
returns decreased sharply.

Maximum impact results are substantial in all production regions.  A
yield reduction of eight percent was applied equally in all regions
as the result of the proposed 1990 organophosphate restrictions.
This reduction in yield when combined with other regulatory actions
resulted in an average annual decrease in net returns of nine
percent in Washington-Idaho, 11 percent in Minnesota-North Dakota,
and 21 percent in Maine during the 1987-1996 period.

Ton&tioos

Tomatoes rank second to potatoes in dollar value among all
vegetables produced in the U.S.  Nearly 85 percent of total
production is used for processing/ with the remainder utilized
fresh.

California is the major tomato growing area, typically accounting
for about 75 percent of the total U.S. crop.  Ninety to 95 percent
of the California crop is used for processing.  Florida is the
second largest state in terms of production/ accounting for six to
eight percent of total U.S. production.  Unlike California/ nearly
all Florida production is for the fresh market.  California harvests
approximately 225,000  acres yearly while Florida harvests 45/000
acres.  There are approximately 1600 tomato farms in California and
400 in Florida.

The value of tomatoes  is much higher for the fresh market/ compared
to the processing market.  Fresh market tomatoes are typically worth
approximately $500 per ton at the farm gate/ with some variance
depending on season/ location/ and quality.  Tomatoes used for
processing are typically sold by producers for $70 to $80 per ton.

Yields per acre are also quite different for processed and fresh
tomatoes.   Tomatoes used for processing are generally direct-seeded
(without transplanting) and have relatively higher plant populations
per acre.   Tomatoes for the fresh market/  at least in Florida/  are
generally transplanted/ and the plants are staked; per acre plant
populations are much lower.

Net returns per acre of production are considerably higher for fresh
tomatoes grown in Florida than for California processing tomatoes.
While tomatoes grown in Florida for the fresh market have lower
yields and higher growing and harvesting costs, the higher price
they command more than offsets these factors.  Net returns to
management and land are estimated at $1500 per acre compared to $700
per acre for California processing tomatoes.

SCENARIO 1

The impact on net returns per acre  from regulatory actions  in the
tomato producing regions of California and Florida are very similar
 (Figure 14).  The 1988  farm worker  safety regulations produce a
minimal  (less than  .3 percent) decline in net returns as measured by
average impacts.  A more noticeable feature of impacts on tomato
producers' net returns  is the difference between average and maximum
impacts.  This difference is explained by the fact that some
regulatory actions  (e.g., the EDB cancellation which occurred in
1984) have a significant effect on  a small number of producers.
Under the maximum impact case/ the  most severe declines in  net
revenue occur in 1987,  with reductions of 1.9 and  .8 percent in
California and Florida, respectively.  Even under the maximum impact
cases the decreases in  average annual net.returns per acre  are less
than one percent in both Florida and California.

Maximum impacts on  yields associated with the proposed 1990
restrictions on fungicides were estimated at 20 percent for both
California and Florida. (>/  Such substantial reductions of.  yield
decrease net returns in California  by 49 percent and in Florida by
39 percent (Figure  14).  Average impacts in California affect net
returns less due to a more modest estimate for yield decline of
approximately 5 percent.

The impact estimates for tomatoes under Scenario 3 must be  viewed
with some caution.  Yield declines  and cost increases were  based on
information provided by pesticide registrants that has not  been
thoroughly reviewed by  EPA.

Green Peas

Green peas are a relatively minor specialty crop, with production
concentrated in the Washington-Oregon and Wisconsin-Minnesota areas.
Wisconsin leads all other states in terms of production:
Approximately 86,000 acres are harvested yearly in Wisconsin
compared to 64,000 acres in Washington.  There are approximately
1,700 farms in Wisconsin and 500 in Washington/  Yields in
Washington average the  highest in the nation due to more capital
intensive farming practices such as pivot irrigation.  This  also
accounts for the high cost of production per acre in comparison to
other states.

     impacts associated with the  fungicide restrictions as well  as
     other actions affecting tomato production.

                                                Scenarios  1  and  3 regulatory  impacts on tomato  production

-------
SCENARIO  1

Average impacts on pea producers' net returns per acre in 1987
result in an  initial  increase of over one percent in Wisconsin
producers' net returns and a corresponding decrease of over seven
percent in Washington's net returns  (Figure 15).  This dichotomy
results from  the  1987 cancellation of dinoseb which affects only
Washington producers.  Their response is to decrease production,
which results in  a commodity price increase of  .53 percent over the
price in  1986.  Wisconsin producers' increase in net returns
reflects  this price increase.  However, the price increase is not
enough to offset  the  costs to Washington producers from the
cancellation  of dinoseb and their net returns subsequently decline.
Additional regulatory impacts (e.g., farm worker safety regulations
in 1988 and organophosphate restrictions in 1992) combine with a
declining price to decrease net returns in Wisconsin up until 1994.


SCENARIO  3

Regulatory impacts in this scenario are similar to those in Scenario
1 up until 1992 (Figure 15).  A noticeable difference occurs in this
year when impact  estimates of proposed organophosphate restrictions
increase  sharply  over those in Scenario 1.  Nevertheless, impacts
are still relatively modest even under the maximum impact case when
net returns decline 2.0 and 7.8 percent in Wisconsin and Washington,
respectively, in  1992t the most severe impact year.

Canebarries
Major caneberry crops include red raspberries, black raspberries,
loganberries, boysenberries, and blackberries.  Commercial cane-
berry crops are grown in the Pacific Northwest, almost exclusively
west of the Cascade mountains in the mild marine climates of Oregon,
Washington and to a lesser extent in California.  Caneberry
production has been declining in recent years, due in part to urban
expansion in the principal berry regions of Oregon and Washington.

A major problem with the estimation of impacts on caneberries is the
lack of information concerning crop production.  Very little
information is available regarding pesticide use and the efficacy of
pesticide alternatives.  The cancellation of pesticide registrations
can have severe impacts on the industry because of the lack of
efficacious alternatives.  In general, only a limited number of
pesticides are registered for use on caneberries.   This is largely
because it is such a minor crop and the cost of registering a
pesticide for use outweighs the profits from modest pesticide sales.

Because of the lack of reliable data on caneberry production as well
as the caneberry market, impact estimates associated with regulatory
scenarios could not be completed.

Peanuts

The peanut  ia  not  actually  a  nut  but  rather a legume,  more closely
related to  the pea and bean.   The major  peanut growing areas/  are
North Carolina-Virginia,  accounting for  approximately  15 to 20
percent of  total U.S.  production,  Georgia-Alabama (60  to 65 percent).
and Texas-Oklahoma (10 to 15  percent).

Overall profitability  of  peanut production  depends  heavily on  the
U.S. farm program  for  peanuts.  According to the  farm  program,
peanuts are classified as either  'quota' or 'additional',  each
having a separate  pricing system.   The price support for quota
peanuts is  based on the national  average cost of  production from the
previous year,, adjusted to  reflect any increase in  the average cost
of production, though  restricting annual price increases to 6
percent.  Quotas were  assigned to farmers on the  basis of historical
allotments, determined primarily  on acreage allotments in place in
1981.-  (Quotas in  1980 were based on  an  acreage allotment.   Since
that time they have been  defined  based on production,  with no  regard
to acreage.)   The  quota support price has been $550 per ton since
1983.  For  purposes of this analysis, quota production was assumed
to equal 0.4 million tons at  a price  of  $558 per  ton.

Additional  or nonquota peanuts may be grown by anyone.   They are
used for oil and export  (with some buy-back provision  if quota
production  is not  adequate  to meet domestic edible  demand in a given
year).  The price  support for additional peanuts  is set to avoid any
net cost to the Government, in effect, making the production of
additional  peanuts  responsive to  free-market condition.

Because of  unreliable  cost  and yield  estimates associated with
various environmental  regulations  and the lack of critical crop
production  parameters  (e.g.,  supply elasticities),  impact  estimates
for the regulatory  scenarios  could not be completed.   However,
several of  the regulatory actions  are expected to have significant
impacts (over 10 percent  decline  in yields)  on peanut  producers
including the suspension  of toxaphene, the  cancellation of certain
fungicides  and use  restrictions stemming from pesticides in
grpundwater regulations.


SUMMARY AND RECOMMENDATIONS

Summary results for the representative livestock  and major field
crop farms  in average  financial condition are  presented in Tables 1
and 2.  Table 1 indicates the average base  net cash farm income for
each producer forecasted  over the  1987-1996  period  and shows the
average annual change  in  income predicted for  the same  period  under
Scenarios 1 and 3.  Table 2 shows  the average  base  debt  to asset
ratio and predicted changes for the forecast period.   As revealed in
these summary results  and the preceding  report, on  average,  major
field crop  and livestock producers  are not  expected to  experience

 large  financial  impacts due  to  EPA actions.  For the  average  impact
 case/  average  annual  decreases  in  farm  income are three percent  or
 less and the resulting changes  in  debt  to  asset ratios are  less  than
 one percent.   Although the average impact  cases indicate  that, on
 average/ the losses, under these scenarios  are minor,  the  impact  on
 any given producer  is a function of both initial' financial  and
 production conditions and the extent  of the  initial cost  and  yield
 impacts that are incurred.   Large  variations in losses incurred  by
 different farmers under any  given  set of EPA actions  are  possible.

 Maximum impact cases  were designed to set  an upper bound  on the
 losses that each of the representative  farms might incur  under each
 scenario.  These cases indicate the income losses that would  be
 incurred if the  representative  farms  were.assumed to  be impacted by
 all the EPA actions that could  possibly affect them,  and  represent
 unlikely worst case scenarios.   Even  under the extreme maximum
 impact cases/  however, none  of  the producers in average financial
 condition go out of business as a  result of  EPA actions.

 Since the ability of  farms to withstand losses is a function  of
 their initial  financial condition/  each scenario of EPA actions  was
 simulated for  representative farms in vulnerable financial
 condition.  Although  the reductions in  net cash farm  income were
 similar for vulnerable farms and farms  in  average financial
 condition/ these income reductions resulted  in larger changes in the
 debt to asset  ratios  for vulnerable farms.  .Only one  of the
 vulnerable farms went out of business any  earlier than it otherwise
 would have due to EPA actions.   Under the  maximum impact  case for
 Scenario 1, the  vulnerable Kansas  wheat cattle farm went  out  of
 business in 1992, as  opposed to in 1993 in the baseline.

 Because of limited  data availability/ the  study did not forecast
 changes in the financial condition of the  specialty crop  farms.
 Instead/ it examined  changes in net returns  per acre  (which reflect
 returns to land  and farmer provided labor).  Summary  results  for the
 specialty crops  are provided in Table 3.   The base net returns per
 acre are indicated  for each  of  the crop and  regions considered/
 along with the absolute and  percentage  changes.

 As indicated in  Table 3, effects on specialty crop producers  are
 fairly small under  Scenario  1.  Net returns  are reduced by  four
 percent or less  under the average  impact case/ and by eight percent
 or less under  the maximum impact case.

 Both average and maximum impact  cases result in significant losses
 for specialty  crop  producers under Scenario  3.  The largest absolute
 reductions in  net returns per acre are  incurred by tomato growers in
 Florida and apple growers in New York and  Michigan, with  decreases
 in net returns of $210/ $132/ and  $67,  respectively,  under  the
 average impact case.  These  dramatic  decreases in net returns may
bring about substantial structural changes in the production  and
markets for the  crops affected.  Large  differences in the impact of
EPA regulations  on  crops grown  in  different  regions occurred  because

some of the proposed restrictions involve pesticides that are used
in some regions and not in others.  Even though the results of this
study must be considered preliminary/ these figures show that EPA
actions could create economic problems for some specialty crop farms
and suggest that the. Agency exercise considerable caution in this
area.

Impacts on potato producers under Scenario 3 are significant,
although the absolute decreases are relatively small  (approximately
$26 in each region) these decreases result in an 11 percent and a 21
percent reduction in net returns per acre in Minnesota/North Dakota
and Maine, respectively.

Impacts on pea producers are relatively modest.  Even under the
maximum impact cases for the most expansive EPA scenario/ net
returns per acre are decreased by less than $5.00 in both of the
regions that were examined.

This study illustrates the advantages,, of examining the impacts of
environmental regulations at the farm'level as well as at the
aggregate national level.  While national analyses provide useful
information concerning the total losses incurred by different
aggregate types of farmers (e.g./ corn farmers as a whole)/ the
impact of environmental regulations on farms' financial conditions
depends on the distribution of those losses among farmers and on the
initial financial conditions of the affected farms.  In order to
determine the effect of EPA regulations on the ability of farms to
survive/ both aggregate and farm level analyses are necessary.

This study highlights the data and analytical requirements necessary
to determine the impacts of EPA actions on agriculture.  Such
requirements include:

     1.   Accurate pesticide  usage  data/

     2.   Accurate pesticide  efficacy data/

     3.   Improved information  on how initial pesticide
          cancellation  effects  change, over time/

     4.   Accurate incidence  data for non-pesticide  related impacts
           (e.g./ underground  storage  tanks)/

     5.   Improved national price-quantity models  to
          predict commodity price changes due to EPA
          actions/ and

     6.   Better information  on the initial  financial  and
          production conditions of  agricultural producers
          and farm level models for estimating changes in
          these over time.

The need for better data and modeling capability is greatest for
specialty crops,  where reliable pesticide usage and efficacy data/
often do not exist/  limited information is available on producers'
initial financial condition,  and few models are available.  EPA is

                                  43

-------
currently compiling a directory of all specialty crop models.
Improvements in pesticide usage data might be obtained by increased
cooperation and cost sharing with USDA and states to fund additional
pesticide usage surveys or to add pesticide usage questions to
surveys designed for. other purposes.  In addition, registrants of
pesticides might be required to provide usage information.  Appendix
H provides a discussion of additional options that might be
considered for improving the data available to complete studies of
this type.  Reliable pesticide usage data, efficacy data, national
price-quantity models, and farm level models are likely to become
increasingly important in the future, as EPA tries to reduce
environmental risks associated with agricultural production in a
cost-effective manner.

               EPA Actions  Considered in  this  Study

As part of this study, each of the program offices at EPA submitted
a description of the regulations that were passed during the past
five years and those that were being considered for the next five
years.  These regulations were reviewed to determine which ones
were likely to have a direct economic impact on the agricultural
sector; regulations having an indirect economic impact were not
included in this analysis because of the difficulty in determining
what portion of their cost would be passed on to agricultural
producers.  The set of potential direct impacts included:

Air       Lead Phasedown:  If lead is banned from gasoline/ farmers
          that use gasoline powered tractors,  combines and trucks
          would have to use a fuel additive or rebuild their
          valves.  These costs were incorporated into Scenario 3.

Air       Agricultural Burning Restrictions:  Agricultural open
          burning of crop residues may be restricted.  Possible
          control techniques include proper fire and fuel manage-
          ment, appropriate burning operations under optimum
          meteorological conditions, and alternative residue
          disposal procedures.  The impact of this regulation was
          not quantified in -this study because of insufficient
          information on its cost and incidence.

OPTS      SARA Title III (jointly with OSWER):  Title III of SARA
          requires farmers to provide information on the chemicals
          that they use and store.  The cost of Sections 302-303
          are estimated to be approximately $50 per farm, and
          apply to 33% of all farms.  Farms are.exempt from 311-
          312 requirements provided that they dp not.employ more
          than 10 full-time employees.  This means that virtually
          all farms are exempt from Section 311-312 requirements.
          SARA Title III costs were incorporated into Scenarios
          1-3.

OSWER     Financial Responsibility Requirements for Petroleum
          Underground Storage Tanks (USTs):  Would require farms
          with petroleum USTs of greater than a 1,100 gallon
          capacity to carry insurance.  This would cost farms
          $2,500 per year.   Information is available on the
          number of covered USTs in each USDA production region;
          however, no information is available concerning the
          types of farms most likely to have them. Insurance
          costs were incorporated into Scenarios 1-3.

OSWER     Technical Standards for Design and Operation of USTs
          Containing Petroleum or Hazardous Substances:  By 1991,
          farms having USTs will have to begin monitoring.  This

                               A-l

-------
          is estimated to cost $500 and will have to be repeated
          at least every 3 years.  If a leak is found, they will
          have to be repaired and upgraded.  No information is
          available on the likelihood of finding leaks in farm
          USTs or the cost of repairing or replacing the tanks.
          By year 10, all USTs will have to be brought up to
          standards, again.  Monitoring costs were incorporated
          into Scenarios 1-3.  Although there is no information
          specific to farm USTs, national data estimate that 15
          percent of all USTs may be leaking.  The estimated cost
          of replacing a 4,000 gallon coated and cathodically
          protected tank system is $21,000 and the cost of upgrading
          an existing tank is $3,050.

OSWER     Waste Oil Management:  There is insufficient information
          to determine whether this is relevant.

Water     Nonpoint Source Guidance and Management Plans:  Under
          legislation passed in February 1987, states were given
          grants to assess the magnitude of NFS problem and to
          develop management plans.  These plans will have to be
          submitted by August 1988. , EPA has until February 1988
          to approve the plans.  Information from Office, of Water
          indicates that this should not be considered a direct
          affect on agriculture because EPA cannot force states
          to implement their management plans, and because actions
          on the part of farmers will be voluntary.

Water     Wellhead Protection Program:  Section ,1428 of SDWA as
          amended in June 1986 mandated states to submit wellhead
          protection programs to EPA.  Although states are required
          to submit plans, there are no federal sanctions for not
          submitting except for the withholding of grant funds.
          Twenty states have begun development of plans.  The
          cost question is difficult to address because there |are
          no minimum federal standards or management strategies
          which states must .include,as part of. an approvable WHP;
          therefore, impacts are likely to vary considerably from
          state to state.  These costs were not quantified in
          this study.

Water     National Estuary Program:  There are no national program
          guidances and/or regulations yet associated with the
          NEP.  The first is expected in 1989.  For agriculture,
          use of pesticides in certain watersheds may be eliminated
          or restricted.  Target reductions of nutrient loadings
          may be established and BMPs may be put into place by
          SCS and state cost sharing programs.  No information is
          currently available to determine the impact of this
          program on agriculture.
                               A-2

-------
Water     Sewage Sludge Regulations:  A proposed rule is planned
          for October 1988.  This rule may limit the amount of
          municipal sludge farmers are allowed to use on their
          fields.  No information currently exists on the limits
          that would be imposed or the costs that farmers would
          bear as a result of this rule.

OPTS      FIFRA/OPP Part 170 (Farm workers):  The proposed rule
          establishes requirements to improve the occupational
          health and safety of workers performing hand labor in
          the fields.  Specific estimates on per acre production
          cost increases for various crops were utilized in this
          analysis and were incorporated into Scenarios 1-3.

OPTS      Pesticides in Groundwater Strategy:   Groundwater
          protection may result in prohibitions of certain water
          soluble pesticides in areas with vulnerable groundwater.
          Three alternative sets of impacts associated with the
          Pesticide in Groundwater Strategy were developed by
          OPTS and used in Scenarios 1-3.

OPTS      Endangered Species Act:  Actions that bring EPA into
          compliance with the Endangered Species Act will impose
          some direct costs on agriculture.  No information
          currently exits to determine the extent of costs imposed
          by the ESA; therefore, these costs were not included in
          this analysis.

OPTS      FIFRA/OPP Individual Actions:  The following individual
          actions were included in this study:  cancellation of
          EDB, toxaphene, dinoseb; restricted use of alachlor;
          cancellation of yield enhancement of cholordimeform;
          and an expansive, intermediate, and conservative scenario
          for actions on the following groups of pesticides:
          fungicides, corn rootworm insecticides, broad .spectrum
          organophosphates, and grain fumigants.


Direct Impacts Included in the Empirical Analysis;

The objective of this study is to examine the cumulative impact
that EPA policies promulgated over the period 1983-1992 have on
the agricultural sector.  It is obviously difficult to predict
what .future EPA policies might look like; therefore, we have
defined three alternative scenarios corresponding to a range of
future EPA policies.  The scenarios can best be summarized as
follows:

     SCENARIO 1:    Past and current EPA actions plus a conservative
                    (low cost) set of assumptions about future
                    actions.


                               A-3

-------
     SCENARIO 2:    Past and current EPA actions plus an inter-
                    mediate (mid cost) set of assumptions about
                    future actions.


     SCENARIO 3:    Past and current EPA actions plus an expansive
                    (high cost) set of assumptions about future
                    actions.
Past and Near Term Actions Included in Scenarios 1-3;

Actions that the Agency has undertaken in the past five years or
plans to undertake .in the very near future were included in all
three scenarios.  These actions are:

EDB - cancellation
Toxaphene - cancellation
Dinoseb - cancellation
SARA Title III
Leaking Underground Storage Tanks
Farm Worker Protection Standards
Chlorodimeform - cancellation of yield enhancement
Alachlor - restricted use.

For actions that there is a great deal of uncertainty over, three
alternative plans were considered, with the most conservative
plan being incorporated into Scenario 1, the intermediate plan
into Scenario 2, and the most expansive plan into Scenario 3.
These actions and the alternative plans are listed below:

Fungicides

     Scenario 3:    EPA would cancel the use of all EBDCs and
                    chlorothalonil.  Captan would not be
                    cancelled.

     Scenario 2:    EPA would cancel.the use of all EBDCs.
                    Chlorothalonil and captan would not be
                    cancelled.

     Scenario 1:    EPA would put additional restrictions on the
                    use of all EBDCs, chlorothalonil and captan
                    (e.g., restricted use, pre-harvest
                    restrictions, limited number of
                    applications).

Corn Rootworm Insecticides

     Scenario 3:    EPA would cancel all of the corn rootworm
                    insecticides.
                               A-4

-------
     Scenario 2:    EPA would cancel all of the corn rootworm
                    insecticides with the exception of one of the
                    organophosphates and one of the carbamates.

     Scenario 1:    EPA would cancel soil use/ but not foliar
                    use, of all of the corn rootworm
                    insecticides.

Broad Spectrum Organophosphates

     Scenario 3:    EPA would cancel three-quarters of all of the
                    broad spectrum OPs.  The most toxic ones
                    would be cancelled.

     Scenario 2:    EPA would cancel one-half of all of the broad
                    spectrum OPs.  The most toxic ones would be
                    cancelled.

     Scenario 1:    EPA would place restrictions on the use of
                    OPs (e.g./ closed cabs).

Grain .Fumigants

     Scenario 3:    EPA would cancel methyl bromide.  Aluminum
                    phosphine and magnesium phosphine would hot
                    be cancelled.

     Scenario 2:.    EPA would put additional restrictions on the
                    use of methyl bromide, aluminum phosphine,
                    and magnesium phosphine..

     Scenario 1:    No action.

Pesticides in Groundwater Strategy

     Scenario 3:    EPA would cancel the use of aldicarb, alachlor,
                    and three triazines over the next five years
                    In^'all counties haying high drastic scores
                    and 20% of the counties having medium drastic.
                    scores.

     Scenario 2:    EPA would cancel the use of aldicarb, alachlor,
                    and three triazines over the next five years
                    in 25% of the counties having high drastic
                    scores.

     Scenario 1:    EPA would cancel the use of aldicarb in 25%
                    of the counties having high drastic scores.
                    Restricted use would be instituted for alachlor
                    and the triazines.  Monitoring would be required
                    for the triazines that have not yet had
                    monitoring required.

                               A-5

Lead Phaseout

     Scenario 1,2:  A total ban of lead in gasoline (for agricul-
                    tural use) was not assumed in these two
                    scenarios.

     Scenario 3:    EPA would eliminate lead in gasoline for
                    agricultural use.

Risk Reductions Corresponding to the Actions Considered;

The objective of the preceding report is to estimate cumulative
costs associated with EPA actions.  To provide some background as
to why EPA has undertaken, or might consider, the actions listed
above, the following section describes the health .and environmental
risks and exposure pathways associated with the substances those
actions are meant to control.

EDB:

Health effects were the primary concern that motivated the cancel-
lation of EDB.  EDB is classified as a likely human carcinogen
and may cause adverse reproductive effects to exposed workers.
The exposure routes were:  food consumption, drinking water, and
worker exposure.  Cancer risk estimates due to occupational
inhalation of EDB range from 1 x 10~  to 3.6 x 10~ .  Millworkers
and farmers had the largest populations of workers at risk, with
16,000 millworkers and 14,000 farmers estimated as being exposed
to EDB through inhalation.  Dietary risks occurred through the
consumption of wheat products, citrus, and tropical fruits.
Cancer risks from EDB to the average U.S. consumer were estimated
to be 3.55 x 10~_-due to wheat product consumption and from 2.8 x
10~  to 1.7 x 10~  due to citrus fruit consumption, depending on
state requirements about fumigation.

Toxaphene:

Ecological qamages were the primary concern motivating the cancel-
lation of toxaphene.  Toxaphene was found to cause adverse reproduc-
tive effects in fish populations at very low concentrations.  It
may be carried for long distance in the upper atmosphere and find
its way into water bodies far from the locations where it was
used.  In addition to the concern about fish populations, laboratory
experiments indicated that toxaphene has both acute and chronic
effects on several bird species.  Finally, human exposure may
occur both through worker exposure (inhalation and dermal) and
dietary exposure.  Estimates of lifetime probability of cancer to
toxaphene applicators (toxaphene was applied to several crops)
ranged from 2 x 10~  to 3 x 1C~ .  Dietary risk was estimated to
be the greatest for local populations of fish consumers in areas
where significant fish contamination had been demonstrated.

                               A-6

-------
Dinoseb:

Exposure to dinoseb may cause a variety of hazards such as develop-
mental toxicity, reproductive toxicity, acute toxicity, induction
of cataracts, and immunotoxicity.  An oncogenicity hazard (resulting
in benign tumors) may also exist.  A particular concern that.led
to the emergency suspension of dinoseb was its potential to cause
birth defects.  Exposure to dinoseb occurred through direct contact
by farm workers.  Approximately 45,000 workers/ including up to
2,200 females, were involved in the application of dinoseb.  A
large number of farm workers and bystanders had the potential to
be exposed to dinoseb during or shortly after application, and
other people had a chance of being exposed by a secondary route
(e.g., laundering of contaminated clothing).  In addition, dinoseb
has been found in groundwater in several states, indicating that
exposure through drinking water is also possible.

Chlorodimeform:

The registrants of Chlorodimeform have voluntarily cancelled it
since the beginning of this project.  Chlorodimeform was used
only on cotton.  The health risk of concern was the possibility
of cancer in exposed workers.

Alachlor:

Risk of cancer is the primary concern associated with alachlpr.
There are multiple routes of exposure:  worker exposure, consumption
of ground water and surface water, and residue on food products.

Farm Worker Safety:

The objective of farm worker safety requirements are to minimize
the acute and .chronic health effects for,pesticide handlers and
field workers.  There are approximately 500,000 handlers and 1.8
million field workers.  The regulations are directed .primarily
towards minimizing the risk of acute poisoning.  There are 20,000
to 300,000 acute poisoning incidences estimated to occur annually
due to farm worker exposure.

Underground Storage Tank Regulations:

The proposed underground storage tank regulations would set
insurance and monitoring requirements for underground petroleum
tanks (with greater than 1,100 gallon capacity) on farms.  The
primary health risks associated with leakage from these tanks are
cancer (caused by benzene, a component of petroleum) and fire and
explosion.  Ecological damages may occur if leakages found their
way into streams.  Risks are greatest in small streams where the
opportunity for dilution is less than in larger streams.


                               A-7

-------
SARA Title III:

Benefits associated with Title III take the form of "negative
reductions in damages".  .Title III is expected to contribute to
human health and welfare in at least two ways:  by helping to
prevent potentially harmful releases of hazardous substances, and
by making it possible to reduce the harm from those releases that
still occur.

Fungicides:

The fungicides OPP may consider for cancellation are classified
as probable human carcinogens.  Exposure routes for fungicides
are:  worker exposure, dietary, and groundwater.  Worker exposure
is the primary concern associated with chlorothalonil at this
point, with dietary exposure the primary concern for both 'captan
and EBDCs; however, evidence of thyroid and teratogenic effects
(birth defects) have been found for EBDCs.   Chlorothalonil and
EBDCs (or their breakdown products) have been found in groundwater.

Broad Spectrum Organophosphates:

There are both human health and ecological  concerns associated
with broad spectrum organophosphates (OPs).  The OPs are acutely
toxic.  They depress an enzyme that causes  an interference with
nerve transmission, and may result in nausea, diarrhea, dizziness,
or death.  In addition, some OPs may result in adverse eye effects
(myopia) and neurological disorders.  Worker exposure, dietary
exposure, and groundwater contamination are all of concern.  '
Ecological impacts are also a concern, since broad spectrum OPs
are acutely toxic to birds and fish, as well as humans.

Corn Rootworm Insecticides:

The health and ecological concerns associated with corn rootworm
insecticides are similar to those for broad spectrum organophos-
phates. However, worker exposure is not thought to be a problem
with corn rootworm insecticides because they are applied in granular.
form, as opposed to a spray.  Hazard to bird populations is a major
concern with corn rootworm insecticides.

Grain Fumigants:

Worker exposure is the primary concern with, grain fumigants.
Methyl bromide may result in acute toxicity (possibly causing
nausea, diarrhea, dizziness, or death) while aluminum phosphine
and magnesium phosphine are neurotoxins.

Pesticides in Groundwater:

Alachlor effects and exposure routes are discussed above.


                               A-8

-------
Aldicarb is an acutely toxic substance that may result in nausea,
diarrhea, dizziness, or death.  The exposure paths of concern for
aldicarb are residues on food (mainly potatoes and citrus crops)
and groundwater contamination.

Triazine herbicide (cyanazine, atrazine, and simazine) exposure
may occur through groundwater and surface water.  Health effects
are the primary concern for these substances.  All of the triazines
are considered possible human carcinogens, and there is some
concern that the triazines can react with nitrites (also found in
groundwater) to form nitrosamines, which are potent animal carcin-
ogens. In addition, exposure to cynanzine may cause birth defects.

Lead in Gasoline:

Lead in gasoline has been shown to increase blood lead levels,
which in turn have been linked to a variety of serious health
effects, particularly in small children.  Recent studies linking
lead to high blood pressure in adult males also are a source of
concern.  People are exposed to lead from gasoline through a
variety of routes, including direct inhalation of lead particles
when they are emitted from vehicles, inhalation of lead contaminated
dust, and ingestion of lead contaminated food.

                     AGSIM Model and Results


                        1.0  Introduction

In examining the impact of EPA actions on the financial condition
of agricultural producers, it is crucial to account for the crop
and livestock price increases that result from these actions.
Failure to account for these price changes would result in an
overestimation of the impact of EPA actions on farmers.  The crop
and livestock price changes resulting from EPA policies were
predicted using AGSIM, a regional econometric-simulation model of
U.S. crop and livestock markets (Bales, Frank, Taylor 1987a,
1987b, 1987c).  The new crop and livestock prices obtained from
AGSIM under each scenario, were then used as inputs to represen-
tative farm models (along wich additional information on production
costs and yield impacts) to determine the change in financial
condition caused by EPA actions.  The set of crop and livestock
prices in the base run of AGSIM (no EPA actions) is presented in
Table B-2 (tables appear at the end of this appendix).  The
change in these prices under Scenarios 1, 2, and 3, are presented
in Tables B-6, B-ll, and B-16, respectively.

In addition to providing information on price changes, AGSIM is
useful in predicting the impact of EPA actions on:  crop acreage,
livestock production, and changes in aggregate producer and
consumer welfare.  All of these impacts are examined in this
appendix; however, only the price changes are essential to the
preceding report.  While the examination of these additional
impacts does not shed any further light on how representative
producers are impacted by EPA actions, it provides a more complete
picture of the cost these actions are likely to have on society
as a whole.
                    2.0  Description of AGSIM

AGSIM simulates regional production of major field crops and
livestock as well as the demand for those commodities.  Together
the demand and supply systems provide estimates of commodity
production, distribution, prices, and the economic welfare of
producers and consumers.  Initial impacts of EPA actions under
each scenario are expressed as inputs to AGSIM in the form of
increased costs of crop production and reduced crop yields.

The crop supply component of AGSIM is comprised of a set of
supply equations for each of 11 regions.  Results from only 10
regions are presented here to correspond to the principal produc-
tion regions.  Crops included in the model are corn, grain sorghum,
barley, oats, wheat, soybeans, cotton, and hay.  Cultivated

                               B-l

-------
summer fallow is treated as another land use in semi-arid regions.
Region definitions are presented below.

     Corn Belt:          Iowa, Illinois, Indiana, Missouri, Ohio
     Lake.States:        Michigan, Minnesota, Wisconsin
     Northern Plains:    Kansas, Nebraska, North Dakota, South
                         Dakota
     Southern Plains:    Oklahoma, Texas
     Mountain States:    Arizona/ Colorado, Idaho, Montana,
                         Nevada, New Mexico, Utah, Wyoming
     Pacific States:     California, Oregon, Washington
     Delta States:       Arkansas, Louisiana, Mississippi
     Southeast:          Alabama, Florida, Georgia, South Carolina
     Appalachia:         Kentucky, North Carolina, Tennessee,
                         Virginia, West Virginia
     Northeast:          Mid-Atlantic States and New England

For each region, the model first determines total acreage planted
or placed in summer fallow and total acreage diverted or set-aside
under farm programs.  Then, a set of equations determine the
proportion of acreage planted to each crop.  Acreage is modeled
as a function of expected returns, which account for target
prices.  Yield per acre, modeled as a time trend.for each crop in
each region is held constant after.1987 (except as altered by EPA
actions).  Yield per acre is multiplied by acreage to calculate
production.  Summing crop production across regions and adding
inventories determines.crop supply.

Crop demands are estimated for cotton lint, hay, grain exports,
grain stocks, food, soybeans, feed, and cottonseed.  The soybean
demand component consists of a crushing, export, and stock demand
function as well as demands for the derivative meal and oil
products.  These functions are primarily determined by relative
prices.

Equating crop supply and demand functions and solving the system
of price-dependent equilibrium excess supply equations provides
annual equilibrium prices;  Prices from one simulated year are
used to calculate net returns for that year.  The system is
recursive.  A price from one year may affect acreage response
the following year.  Expected net returns drive the acreage
response functions.  The maximum of price from the previous
simulated year and the effective support price is used to calculate
expected net returns.  That is, price from the previous year
serves as a price expectation for the following year.

The livestock sector of AGSIM is linked to the crop sector through
feed and hay prices which determine the supply and inventory of
livestock products:  beef, veal, pork, chicken, and milk..  Also,
quantities of feed demanded are influenced by livestock prices.
                               B-2

-------
The model runs twice to simulate a technological change.  The
initial, or base run simulates commodity market conditions without
any technological change.  A second run simulates market condi-
tions under the new,technology, showing differences attributable
to the technology.  The three scenarios were simulated by changing
the yields, and both fixed and variable production costs of
selected crops in particular regions.

The principal limitation on the interpretation of AGSIM results
is that the model is not specific and detailed enough to recognize
any particular technological change.  That is, any two changes
having identical impacts on net returns would be treated identi-
cally by AGSIM and, thus, calculated economic impacts would be
identical.  The factors that might limit use of any particular
technology may not be incorporated in AGSIM.  Overestimating
impacts is a real possibility.

Income impacts may be overestimated because AGSIM does not account
for the effects of price changes on commodity program payments.
Commodity programs may stabilize farm income.  When prices rise,
revenues derived from commodity sales rise, but deficiency payments
fall, thereby partially offsetting the revenue increase.  AGSIM
calculates farm income based on a market price ignoring deficiency
payments and hence the reduction in payments likely to accompany
an increase in market price.

AGSIM simulates production and the operation of commodity markets
over a ten year .horizon.  The year-by-year changes cannot be
considered market forecasts.  .Instead, the multi-year infor-
mation is designed to provide a longrun description of the policy
impacts.  AGSIM is designed to equilibrate supply and demand
forces in each simulated year.  Actual commodity markets may
operate, at times, with much greater or lesser speed than AGSIM
suggests.  For example, price expectations modeled in AGSIM do
not rapidly adjust to changed conditions.  That expectations
mechanism is empirically adequate for historical data.  Whether
that expectation formation mechanism will hold in the future is a
matter of .speculation.  The particular type of equilibrium assumed
for commodity markets in AGSIM leads to stocks being rapidly
depleted.  In recent years, stocks have demonstrated much more
inertia, suggesting that prices may not increase as rapidly as
the AGSIM simulations suggest.  Again, these examples indicate
that the presented time paths variables follow are primarily
descriptive, rather than exact.

Information from the AGSIM base run and the three alternative
policy runs is presented in this appendix.  Information from a
base run, which is common to all three policy scenarios, is
presented in Tables B-l through B-4.  This information includes
crop acreage by commodity, commodity prices (farm level prices
for crops and retail prices for dairy and livestock commodities),
crop and livestock income, and livestock production.  Crop income

                               B-3

-------
is calculated by subtracting most fixed and variable production
costs from gross revenue.  Land costs and commodity program
payments are not considered in that calculation.  Changes in
acreage,, prices, and income are presented for each policy scenario.
Also, several variables measuring income changes throughout the
agricultural sector and impacts on consumers are shown.

Gains and losses resulting from regulations affecting crop
productivity may go far beyond the farms for which yields and
costs of production are immediately affected.  The crop sector
supplies the dairy and livestock sectors.  Increased crop produc-
tion costs and reduced production may lead to higher feed costs
and hence, higher meat and dairy products.  Other industries
depend on the success of crop enterprises.  Industries that
process and market field crops as well as dairy and livestock
products depend on the price and volume of those products.  AGSIM
provides, some estimates of the aggregate gains and losses to
industries up and'down the food and fiber marketing chain.

The heading, "Crop Consumer Effect" in the boxheads of Tables B-9,
B-14, and B-19 refers to the sum of gains or losses to consumers
(that is, the effects .of higher prices for all food and fiber
products) and to all industries beyond the farm gate that depend
on crop production.  These industries include, but are not limited
to, processors, packers, retail grocers, and transportation
firms.  One should expect that as crop production is carried out
less efficiently, farm prices will rise and output will fall.
The intermediate industries will have reduced business and the
price increase, representing higher input prices to processors,
will imply reduced profits for the various processing industries.
With higher input and output prices throughout the marketing
chain, consumers should face higher retail prices.

Similarly, the heading "Livestock Consumer Effect" refers to the
sum of gains and losses beginning with livestock purchasers and
ending with consumers of meat and dairy products.  These gains
and losses are a subset, of those included in the "Crop Consumer
Effect".  The "Livestock Consumer Effect" is smaller, in absolute
value, than the "Crop Consumer Effect" because the latter effect
includes crop uses that do not support livestock production.
Only a small portion of wheat supply, for example, is used for
livestock feed.  Cotton is not used for livestock feed, although
cottonseed meal is used for feed.

Just and Hueth showed that in vertically related industries where
the output of each industry is an input for the industry one
step up the marketing chain, the welfare effects of an imposed
price distortion in an initial or intermediate market on all
forward industries can be captured by measuring the change in
consumers' surplus (the difference between what consumers are
willing to pay and what they are required to pay to acquire goods
and services).  That is, if a calculation to compute changes in

                               B-4

-------
consumers' surplus were carried out on an initial or intermediate-
level general equilibrium demand function, the change should be
interpreted as the change in final consumers'  surplus plus the
changes in all forward industry rents.  Chavas and Collins
generalized this analysis to include technological change or
distortion.  These ideas are incorporated in the AGSIM calcula-
tions presented here.


                           3.0   Results

As discussed above, the impact of EPA actions on crop producers1
are entered into AGSIM in the form of yield decreases and/or,
production cost increases.  These impacts result in a decline in
crop production and an increase in crop prices - a cost for crop
purchasers.  Yield and cost changes in Scenario 1 are the least
of the three scenarios.  The changes induce losses for both crop
consumers and producers.  As a result of higher costs of, feeding
livestock, livestock income decreases, but livestock purchasers.
are affected less since livestock prices change less then crop
prices.

Scenarios 2 and 3 generate greater effects than Scenario 1,
primarily because of larger corn yield declines beginning in
1992.  Prior to 1992, these two scenarios have somewhat greater
cost changes than Scenario 1, while Scenario 3 has greater changes
'than Scenario 2.  Thus, Scenarios 2 and 3 cause somewhat larger
price changes than Scenario 1, during that time period.  As a
result, crop consumers, livestock producers, and livestock
consumers generally lose more and crop producers lose less than
in Scenario 1.  Beginning in 1992, prices, in Scenarios 2 and 3
increase so much that crop income increases.  In effect, the
relatively large yield and cost changes of Scenarios 2 and 3
cause an income transfer from crop consumers to crop producers.;
Crop consumers, livestock producers, and livestock consumers, lose
more while producers gain more for Scenario 3 than Scenario 2,
during 1992-96.

While crop producers gain in aggregate under Scenarios 2 and 3
during 1992-96, income does not increase for all crops and all
regions.  The cost and yield changes cause a complex change of
acreages and prices for different crops.  Income decreases for
some crops because price increases do not outweigh cost increases
and/or yield declines.  Crop income declines in some regions.
For example, the Northeast and Appalachian States lose in Scenario
3 because they have the highest corn yield losses, despite higher
corn prices.

Scenario 1

Scenario 1 assumes the smallest initial direct changes in yields
and costs among the three scenarios.  Only cotton, soybeans, and

                               B-5

-------
wheat yields decrease, all by less than 0.5 percent.   Fixed
costs generally increase by less than $1 per acre, but never by
more than $1.50 per acre.  Similarly, variable production costs
generally increase by less than $1 per acre.  Thus, changes in
acreage, output, and prices are smaller than changes  estimated
for Scenarios 2 and 3.

Acreage and Prices.  Total crop acreage steadily decreases, but
never by more than 200,000 acres which is less than 0.1 percent
of baseline total crop acreage (Table B-5).  The acreage of all
crops decreases in most years.  Price changes for field crops
never exceed $0.022 per bushel and are generally less.than $0.01
per bushel (Table B-6).  Retail prices for livestock  products
either fail to change or change by less than $0.01 per pound.
Price decreases occur for soybean meal in 1991-93 because soybean
production increases.  AGSIM predicts that higher hay prices
encourage the slaughter of cattle and calves.  The result is that
beef and veal prices fall by less than $0.01 after 1991.

Income.  Since the cost increases outweigh the price  increases,
total crop income (net of fixed and variable costs) decreases in
all years (Table B-7).  The greatest income loss, $339 million,
which is about 4 percent of baseline total crop.income, occurs' in
1988. The losses become smaller in succeeding years as cost and
yield changes decline.  On average, the crop income losses are
less than $1 per baseline crop acre.  However, income (net of
variable costs) increases for barley in 1992-93 and for hay from
1991-96.  In 1987, there are crop income gains (net of fixed and
variable costs) in some regions.  These gains are exceeded by
losses in the Delta States and Southeast (Table B-8).  These two
regions have relatively high soybean and cotton yield losses from
1987-89.  From 1988 on, income declines in all regions.

Consumer Effects.   Crop consumers lose from higher.prices and
lower production (Table B-9).  The losses become steadily larger,
varying from $23 million in 1987 and to $95 million in 1996.
Livestock producers generally suffer income losses due to higher
feed and hay costs and unchanged or lower livestock prices
beginning in 1988.  The greatest loss, $42 million (less than 0.1
percent of baseline income for the 5 livestock products), occurs
in 1993.  Additionally, livestock consumers would gain in some
years and lose in others.

Scenario 2

Scenario 2 has greater cost and yield changes than Scenario 1.
The largest differences from Scenario 1 are the corn yield declines
beginning in 1992 due to restrictions on soil insecticides.  Corn
yield losses exceed 8 percent in the Corn Belt and Northern
Plains and vary from 2 to 6 percent in the remaining regions.
The yield losses moderate in later years.  Some variable costs
increase noticeably in 1992.  Cotton costs increase by $5.40 in

                               B-6

-------
the Delta  States.  However, corn costs decrease by less than $2
per acre in  the Corn Belt, Northern Plains, Southern Plains, and
Pacific States.

Acreage and  Prices.  Prior to 1992, price and acreage changes are
greater than Scenario  1.  As a result, total crop acreage declines
range  from 19,000  in 1987 to 108,000 in 1991 (Table B-10).  From
1988 to 1991,  total crop acreage declines less for Scenario 2
than for Scenario  1.   Higher crop prices in Scenario 2 seem to
explain this result.   Soybean price increases by $0.18 per bushel
in 1988 and  by lesser  amounts in 1987 and 1989 (Table B-ll).
During these three years, the Appalachian, Delta, and Southeastern
States suffer  greater  soybean yield losses than in Scenario 1.
These  initial  soybean  yield losses reduce soybean and increase
corn and cotton acreage, primarily due to similar changes in the
Southeast.   The prices of meal and oil products of cotton and
soybeans increase  during 1987-89 as a result of lower soybean
production and higher  prices.

The larger corn yield  losses (as compared to Scenario 1) beginning
in 1992 cause  a noticeable change in results from Scenario 1.
Total  crop acreage decreases by 300,000 in 1992, but increases by
46,000 in  1993 to  226,000 in 1996 (Table B-10).  Corn price
increases  by $0.51 per bushel in 1992 (Table B-ll).  AGSIM predicts
an interesting pattern for corn and soybeans.  Soybean acreage
increases  and  price decreases in 1992, because corn cost and
-yield  changes  reducfe expected corn returns and, hence, planted
acreage.   The  higher corn price in 1992 encourages farmers to
shift  acreage  from soybeans and other crops to corn.  Corn price
rises  less in  following years, and the prices of barley, oats,
wheat, soybeans, and cotton also increase as the acreage and
production of  those crops decrease.  As a result, prices of meal
and oil products of cotton and soybeans also rise.  Since sorghum
is a good  feed substitute for corn, sorghum demand rises causing
its price  and  acreage  to rise.  Hay acreage increases in 1988 and
later  years  causing price decreases in most years.  In 1992,
lower  feed and hay prices reduce retail livestock prices.  After
tha.t,  higher feed  costs increase all livestock prices in some
years. However, all price changes are less than $0.10 per pound.
Beef and veal  prices increase in some years and decrease in others:

Income.  Crop  income (net of fixed and variable costs) rises $159
million in 1987, but falls $111 million in 1988 and $315 million
in 1991 after  fixed costs increase in 1988 (by the same amount as
in Scenario  1) and groundwater regulations begin in 1990 (Table
B-12). All  of those income changes are less than 2 percent of
baseline total crop income.  Income (net of variable costs only)
decreases  for  all  crops except soybeans, barley, oats, and hay in
1987 and soybeans  in 1988, because cost increases outweigh price
increases.   Beginning  in 1992, crop income increases because .
price  increases, particularly for corn and soybeans, outweigh
cost increases.  Crop  income increases the most in 1992, $1.9

                               B-7

-------
billion (12 percent of baseline crop income) or an average of
about $5 per crop acre, but the increases become smaller as cost
and yield changes decline over time.  After 1992, income rises
for corn (the crop suffering the greatest regulation induced per-
acre production loss), and soybeans, but decreases for barley,
oats, wheat, and hay in some years.

Prior to 1992, crop income (net of fixed and variable costs)
falls in most regions (Table B-13).  In 1987, before fixed costs
increase, income increases in the Corn Belt, Lake States, North-
east, and Appalachian States.  From 1988 to 1991, crop income
decreases in all regions but the Corn Belt in 1988-89.  In 1992
and later years, income increases in all regions except the
Delta States in 1992 because soybean prices fall and in the
Mountain and Northeastern States in 1996 because higher crop
prices no longer rise enough to outweigh cost increases and yield
losses.

Consumer Effects.  Consumers lose much more in Scenario 2 than in
Scenario 1 (Table B-14}.  Prior to 1992, crop consumer loss peaks
at $272 million and declines to $45 million in 1991.  Because of
the large price.increases after 1992, the consumer loss peaks at
$2.8 billion in 1992 but falls to $1.5 billion in 1996.  Due to
higher feed costs and modest livestock price increases, livestock
income declines after 1987.  Before the corn yield losses have
their full effect on feed prices in 1993, livestock producer
losses do not exceed $100 million (less than 0.1 percent of
baseline income .for the 5 livestock products).  In 1993 and some
later years, their losses exceed $1 billion (2 percent of livestock
income).  Before the corn yield losses have their full effect,
livestock .consumers have losses of less than $100 million while
gaining in 1991-92 when beef prices fall.  In 1993-94, livestock
consumers lose more than $2 billion.  However, lower beef and
veal prices cause consumer gains in 1996.

Scenario 3

Scenario 3 has greater fixed cost changes throughout the simulation
than Scenario 2.  Yield losses and variable cost changes are
greater during 1990-96.  In particular, greater corn yield losses
occur after 1991, than in Scenario 2.  Corn yield losses are
approximately 23 percent for the Northeast, 13 percent for the
Appalachian States, and 10 percent for the Corn Belt and Northern
Plains in 1992.  Production costs are also greater than for
Scenario 2; cost increases approach $12 per acre in the Northeast
and Southeast and $14 per acre in Appalachian States in 1992.
The yield losses and cost changes moderate in later years.
Fixed costs also increase more than Scenario 2 but never by more
than $2.25 per acre.  The result is greater price changes, income
changes, and consumer losses than for Scenario 2.  The two
scenarios produce identical results for 1987.


                               B-8

-------
Acreage and Prices.  Prior to 1992, total crop acreage in Scenario
3 decreases, ranging from 57,000 in 1988 to 141,000 in 1991.
These changes are greater than those in Scenario 2 for 1988-91,
but less than those in Scenario 1 for 1987-89 (Table B-15).  The
pattern of individual crop acreage and price changes is very
similar to Scenario. 2 for 1988-91.  However, acreage changes
tend to be greater for Scenario 3 than Scenario 2.  Also, soybean
acreage increases in 1991 rather than decreases.  Price changes
for Scenario 3 are also greater than Scenario 2, but soybean,
soybean meal, and cottonseed meal prices increase in 1990-91
rather than decrease (Table B-16).  Some livestock prices do not
change during 1988-91, but increases of $0.003 per pound or less
occur for beef and pork.

For 1992 and later years when the larger corn yield losses occur,
total crop acreage is less for Scenario 3 than Scenario 2.
Total crop area decreases by 505,000 acres in 1992, decreases by
lesser amounts in 1993-94, and increases by less than 200,000
acres in 1995-96 (Table B-15).  Scenario 3 shows the same pattern
of corn and soybean acreage changes as Scenario 2, but has greater
price changes.  Corn price increases by $0.78 per bushel and
soybean price decreases by $0.26 per bushel in 1992, reflecting
greater corn acreage decreases and soybean increases for Scenario
3 (Table B-16).  The higher corn prices encourage farmers to shift
acreage from other crops to corn causing the prices of the crops
to increase.  As a result, the price of soybeans increases in
1993-96, with its greatest increase, $0.43, in 1994. : Barley
acreage increases from 1994-96, but did not in Scenario 2;
However, hay acreage does not begin to increase' until 1995, while
in Scenario 2 it began to increase in 1993.  Higher feed prices
cause higher pork and chicken prices.  Most livestock prices do
not change by more than $0.10 per pound, but pork price increases
by $0.13 per pound in 1994.  Beef prices decrease $0.016 per
pound or less in 1992 and .1996.  Veal prices decrease $0.067 per
pound or less through the entire time period.

Income.  Total crop income (net of fixed, and variable, costs)
declines during 1988-1991, ranging from'$200 million in 1988 to
$303 million in 1991, approximately 2 percent of baseline crop
income (Table B-17).  Income declines more than for Scenario 2 in
1988-90.  In 1991, income decreases less for Scenario 3 than
Scenario 2 because of higher soybean prices in Scenario 3.
Income (net of variable costs only) decreases for all crops
except corn and sorghum in 1990-91 and barley and hay in 1991.
Beginning in 1992, crop income (net of fixed and variable costs)
increases because of price increases that outweigh yield and cost
changes.  Crop income increases by $2.6 billion in 1992 (16
percent of baseline income), approaching an average of $7 per
crop acre, but increases are smaller in later years as cost and
yield changes decrease.  These crop income increases are greater
than those in Scenario 2.  After 1992, income (net of variable
costs only) increases for all crops in most years.

                               B-9

-------
From 1988-91, regional crop income (net of fixed and variable
costs) decreases for all regions except the Corn Belt in 1988-8-9,
when it benefits from higher soybean prices (Table B-18).  From
1992-96, most regions gain, but some lose.  The Delta States
lose in 1992 due to lower soybean prices.  The Northeast and
Appalachian States lose in all those years, because they incur
relatively high corn yield losses.  In most regions, corn replaces
soybeans as corn price rises.  However, corn acreage in the
Northeast and Appalachian States is replaced by soybeans, resulting
in income declines.  In Scenario 2, these two regions generally
did not lose although the Northeast lost in 1996.

Consumer Effects.;  Consumers lose in all years due to higher
prices and lower production.  Prior to 1992, the greatest consumer
loss is §280 million in. 1988.  Consumer loss falls to $170 million
in 1989 but then rises to $206 million in 1991.  After the
comparatively large price increases beginning in 1992/ consumer
loss peaks at $4.4 billion in 1992 declining to $2.2 billion in
1996.  These consumer losses are larger than those in Scenario 2.
Livestock effects are identical for Scenarios 2 and 3 in 1988.
Livestock income falls more under Scenario 3 than Scenario 2 from
1989-96 due to. higher feed costs which outweigh livestock price
increases.  Livestock income declines range from $3.5 million in
1989 to $122 million in 1992 (less than 0.2 percent of baseline
income for the 5 livestock products).  After the corn yield
losses have their full effect on feed prices, 'livestock income
decreases by $2.5 billion in 1993 (about 3 percent of baseline
livestock income), ranging from about $1 billion to $2 billion in
later years.  From 1989 to 1993, livestock consumers incur losses
of less than $86 million while gaining in 1992 when beef prices
fall slightly.  After 1992, livestock consumers suffer greater
losses than under. Scenario 2, exceeding $3 billion in 1993-94.

            National Price-Quantity Model and Results

                      1.0  Model  Description

The model used to estimate national commodity price-quantity
impacts closely follows  the model developed by Lichtenberg et
al., I/ with some modifications required to overcome data defic-
iencies.  With estimates of national  impacts on production for
each commodity—through  both increased costs and decreased yields-
-changes in marginal costs were estimated.  The resulting changes
in commodity production  and price at  the national level were then
assessed with consideration of supply and demand elasticities.
Specific algebraic equations used to  define the model are as
follows:

     (1)     PQ = MCQ

                   P (dY/Y.J  + (dC/Y,J
     (2)     dMC = -=-
                       1 - (dY/YQ)

     (3)     dP/PQ = [es/(egeD)](dMC/MC)

     (4)     dQ/Q = [eDes/(es - eD)](dMC/MC)

     where:
          P  = commodity baseline price, farm level

          MC  = baseline commodity marginal cost of production

          dY = change in yield per acre of crop production from
               the regulatory scenario

          dC = change in variable cost per acre from the regula-
               tory scenario
          ec = elasticity of supply
           3

          e_ = elasticity of demand

          Q  = total baseline quantity of commodity production

Changes in producer and consumer surplus were then approximated.
To estimate changes in producer surplus, it was assumed that all
planned reductions in output would be achieved by shifts in
marginal production inputs (where zero economic profits were

being earned in the baseline) to an alternative equally profitable
crop.  Economic profits on this marginal production would be the
same before and after the regulatory scenarios.  The change from
the baseline in total revenue earned by producers would be:

     (5)     dR = P1Ql - PQQo

and since price equals marginal cost, the cost savings would be:

     (6)     CTS = PQ(Q0 - C^).

The change in costs for the acreage remaining in production is

     (7)     dTC = AidC.

Accordingly, the change in producer surplus from the baseline is
defined as

     (8)     dPS = dR + CTS - dTC.

The change in consumer surplus from the baseline was approximated
using the following relationship:

     (9)     dCS = -(P. - P0)(Qi * Q0)/2

     where:

          dR  = change in total revenue

          CTS = cost savings
           Q. = production in year i

          dTC = change in total production cost

           A. = commodity acreage in year i

          dC  = change in cost per acre from the regulatory
                scenario
          dPS = change in producer surplus

          dCS = change in consumer surplus.

This model presumes that all other variables not considered will
remain constant and thus have no affect on the model results.
                         2.0   Data  Inputs

National information was compiled on baseline price, harvested
acreage, production, farm size, and yield for each of the six
specialty crops.  The baseline commodity prices, harvested acre-
ages, and production quantities used in this study are an average
from 1981-1985 as obtained from various issues of Agricultural
Statistics (Table C-l).  Commodity prices were adjusted by the
GNP Implicit Price Deflator to reflect constant 1986 dollars.

In order to assess -the impacts of regulatory costs on per acre
net returns, a definition of a typical commercial farm, in terms
of acreage, was necessary.  Such estimates were obtained from a
poll of extension crop production specialists (a DELPHI approach)
and from estimates obtained in crop enterprise production budgets.
Because farm size is highly variable within each region, the
estimates presented in Table C-l and used in the impact analysis
must be interpreted with caution.

Estimates of supply and demand elasticities were obtained from
several sources, both published and unpublished.  Elasticity
estimates are presented in Table C-2.

National estimates of variable cost and yield changes associated
with environmental regulations for each specialty crop under
three scenarios were provided by EPA.  The yearly estimates are
provided as the change from a base year prior to the initiation
of regulatory impacts (Table C-3).


                       3.0  Model Results

Results of the National Price-Quantity Model are presented in
Tables C-4 through C-18 as the percent change in production,
price, consumer surplus and producer surplus from a base year of
no regulatory impacts.  Effects of each policy scenario are
examined under each of the four specialty crops.  Data limitations
prevented analyses of peanuts and caneberries.

                    REPFARM Model and Results


                1.0  Description of REPFARM Model

REPFARM is a whole-farm, recursive programming-simulation model
which is capable of using a wide variety of farm policy, produc-
tion, and market environments in order to provide financial
impact information for a variety of representative farms across
the United States.  REPFARM essentially links a set of accounting
decision subroutines with a set of optimizing subroutines.  The
optimizing subroutines annually adjust the mix of crop enterprises
produced on the farm based upon estimated returns for each
enterprise.  The accounting subroutines calculate farm income and
expenses, value of assets and liabilities, as well as other
financial information associated with the production decisions
made each year.

REPFARM is capable of simulating the annual production and
financial operations of a representative farm for a period of
1-10 years.  The model utilizes user-specified data sets which
contain information relative to the partiqular representative
farm being simulated.  Information about a particular farm
contained in a data set includes farm size, acres owned and
leased, initial values of farm assets and liabilities, off-farm
income, family living expenses, itemized expenses for the farm
such as taxes and insurance, as well as acreages, yields, produc-
tion costs, and labor requirements of each crop enterprise produced
on the farm and herd size, input costs, and labor requirements of
each livestock enterprise produced on the farm.  Additional
information which must also be supplied by the user on an annual
basis includes itemized inflation indexes for various production
expense items, interest rates for short-term, intermediate-term,
and long-term loans, machinery depreciation rates, income tax
rates, market prices for all crop and livestock enterprises
included on the farm as well as farm policy -data such as loan
rates, target prices, crop set-asides,  diversion payment rates,
and payment limitations.

REPFARM can simulate a representative farm in a deterministic or
stochastic mode.  In the deterministic mode,  the farm is simulated
with specified crop and livestock market prices and crop yields
for each year of simulation.  Model output consists of annual
financial statements for the farm.  These financial statements
include itemized income statements, cashflow statements, and
balance sheets.  Additional production information is also provided
relating to the acreage and production of each crop enterprise.
In the stochastic mode, several iterations are performed for each
year of simulation using variable crop yields and crop and
livestock market prices.  Model output in this mode consists

                               D-l

-------
primarily of annual mean and variance estimates of selected
financial measures and production items.  REPFARM was simulated
in the deterministic mode in this study.

Three key assumptions that were made in the baseline projections
of each of the REPFARM models are:

     1)   production costs were assumed to increase at two percent
          per year,

     2)   crop yield.was assumed to increase at two percent per
          year, and

     3)   the current farm bill was assumed to be in effect
          through 1990 and policy variables were held constant at
          the 1990 level for the remaining forecast period.

If these assumptions overestimate the financial well-being of the
representative producers in the baseline,  then the ability of the
producers to bear the costs of environmental regulations will be
overestimated.  Likewise, if these assumptions result in an
underestimation of producers well-being, then the ability of
producers to bear the costs of environmental regulations will be
underestimated.
             2.0   Description  of  Representative  Farms

Representative farms evaluated in this study were developed from
data obtained from the USDA's 1986 Farm Costs and Returns Survey.
Three general types of farms considered included a Mississippi
cotton soybean farm, and Illinois corn soybean farm, and a Kansas
wheat cattle farm.  For each one of these general farm types, two
representative farm data sets were constructed:   one representing
a farm in an average financial position and another representing
a farm in a vulnerable financial position.  Representative farm
data sets for farms in an average financial position were developed
from data on all farms meeting the specified state/enterprise
definition.  Representative farm data sets for farms in a vul-
nerable financial position were developed from data on all farms
meeting the state/enterprise definition plus the additional
requirements of a negative net cash income and a debt to asset
ratio greater than 0.40.


2.1  Illinois Corn Soybean Farms

The two representative Illinois corn soybean farms were developed
from survey information on farms in Illinois which were classified
as cash grain farms (cash grain sales represented the largest
portion of gross income for the farm) and produced corn and
soybeans.  Survey observations fitting this description represent

                               D-2

-------
an expanded number of 30,837 farms in Illinois (Table D-l) and
were used to estimate the characteristics of the corn soybean
farm in an average financial position (Table D-2).  Of these
30,837 farms, approximately 9.9% were determined to be in a
vulnerable position (as defined above) and survey observations
relating to this group of farms were used to develop the charac-
teristics of the corn soybean farm in a vulnerable financial
position (Table 0-2).

2.2  Mississippi Cotton Soybean Farms

The two representative Mississippi cotton soybean farms were
developed from survey information on farms in Mississippi which
were classified as field crop farms (field crop sales represented
the largest portion of gross income for the farm) and produced
cotton and soybeans.  Survey observations fitting this description
represent an expanded number of 1,798 farms in Mississippi (Table
0-1) and were to estimate the characteristics of the cotton
soybean farm in an average financial position (Table 0-3).  Of
these 1,798 farms, approximately 14.2% were determined to be in a
vulnerable financial position (as defined above) and survey
observations relating to this group of farms were used to develop
the characteristics of the cotton soybean farm in a vulnerable
financial position (Table 0-3).

2.3  Kansas Wheat Cattle Farms

The two representative Kansas wheat cattle farms were developed
from survey information on farms in Kansas which produced wheat
and had sales of cattle.  Survey observations fitting this
description represent an expanded number of 19,966 farms in
Kansas (Table D-l) and were used to estimate the characteristics
of the wheat cattle farms in an average financial position (Table
D-4).  Of these 19,966 farms, approximately 7.1% were determined
to be in a vulnerable financial position (as defined above) and
survey observations relating to this group of farms were used to
develop the characteristics of the wheat cattle farm in a vulner-
able position (Table 0-4).


                 3.0 EPA Supplied REPFARM Inputs

EPA actions are entered into the REPFARM model as:

     *    changes in variable production costs,
     *    changes in fixed production costs,
     *    changes in crop yields, and
     *    changes in crop and livestock prices.

The changes in crop and livestock prices were obtained from AGSIM
and are described in Appendix B.  The first year cost and yield
impacts assumed for each of the REPFARM models are described in

                               0-3

by EPA Program Offices.  Impacts of pesticide cancellations were
assumed to dissipate evenly over a seven year period.


                        4.0  REPFARM Output

The impact of EPA actions on the financial condition of each of
the representative farms was determined by examining:

     *  the change in net cash farm income due to EPA actions, and
     *  the change in debt asset ratios due to EPA actions.

Three major field crop and livestock farms in two financial
conditions were created, resulting in a total of six different
representative farms:

     * an Illinois Corn Soybean Farm
       - in average financial condition
       - in vulnerable financial condition

     * a Mississippi Cotton Soybean Farm
       - in average financial condition
       - in vulnerable financial condition

     * a Kansas Wheat Cattle Farm
       - in average financial condition
       - in vulnerable financial condition

For each REPFARM in each scenario, two alternative sets of impacts
were considered:

     * A Maximum Impact Case;  In this case it is assumed that
       the producer is impacted by every regulation that may
       possibly affect a producer of that type.

     * An Average Impact Case;   In this case it  is assumed that
       the producer experiences the average impact of producers
       of that type - e.g., if 50% of all producer of a given
       type experience a $2.00/acre cost, we would assume a
       $1.00/acre cost for the average impacted producer.

The net cash farm income and debt to asset ratios of each of these
farms is examined for each of the three alternative EPA scenarios
defined in this study.  This output is presented in Figures Dl -
018.

                Income Budget  Analysis  and  Results


                      1.0  Budgeting Analysis

To more clearly assess regulatory impacts on an individual unit
of production for a given commodity and region, a budgeting analysis
was used.  Baseline conditions were defined as net returns to
management and land for one acre of production prior to any
regulatory action.  These conditions were calculated from regional
production cost and yield estimates and national price estimates.
Total production cost estimates were obtained from crop enterprise
budgets compiled by the USDA Cooperative Extension Service in
each appropriate state.  Crop enterprise budgets typically catego-
rize total costs as variable and fixed.  Variable costs are those
which vary according  to the level of production.  Fixed costs are
those which (in the short run) are unrelated to production levels.

Enterprise budgets vary in their treatment of expensing the cost
of owner provided inputs.  For this study, the cost of owner
provided land and management were excluded.  Any net returns
would then be attributable to these factors of production.  To
the extent possible,  all budgets were adjusted to be comparable.
In instances where a  production region consisted of two or more
states (e.g., Idaho and Washington potatoes) a production weighted
total cost of production was calculated.  All costs were adjusted
by the Index of Prices Paid by Farmers to reflect 1986 dollars.

The baseline-conditions were then adjusted by the cost and yield
impact estimates and  the national price change estimates (developed
from the national price-quantity model and adjusted for regional
differences) to estimate the post-impact net returns per acre
for each regulatory scenario by region and crop.  It is expected
net returns per acre  will typically decrease from the influence
of regulatory impacts because of:

     1.   increased variable costs per acre of production, and
     2.   decreases in yield which lowers production and thus lowers
          revenue per acre.

Ameliorating these negative effects on net revenue would be an
increase in price caused by a national decline in supply due to
decreased production  nationwide.

Algebraically, the farm income budgeting model can be expressed as:

     NR.  = NR  + dTR  - dC.
       1     O
                               E-l

-------
     Since TR is dependent on price and production,
          dTR = P.Q. - PoQQ.
     Thus,
NR.  = NRQ
                      P.Q. - PQQo - dC.
     Where:
          NR. =  Net returns per acre of commodity production
                 after the regulatory scenario,
          NR
       Net returns per acre or commodity production
                 before the regulatory scenario,

          dTR =  change in total revenue,

           dC =  change in total costs;

           P. =  commodity price after the regulatory scenario,

           P  =  commodity baseline price

           Q. =  commodity, production per acre after the regulatory
                 scenario, and

           Q  =  commodity production per acre under baseline
                 conditions.


                         2.0   Data  Inputs

Production cost estimates and baseline net returns for each
specialty crop production region (Table E-l) along with an estimate
of an average price and production (Appendix C, Table C-l) were
required to complete this analysis.  Regional estimates of average
and maximum variable cost and yield changes associated with
environmental regulations for each specialty crop under each
scenario were provided by EPA.  First year production cost and
yield changes are presented in Tables E-2 through E-5.


                        3.0   Model  Results

Regulatory impacts on net returns which consider effects on product
price, quantity of production and production costs are presented
graphically in Figures E-l through E-9.  Average and maximum
impacts are measured from a baseline net return (no regulatory
impact) for each of the specialty crops under the three policy
scenarios.

Cost = $50/covered farm.
Assumed 1/3 of all farms
covered.

Cost = $2,500.  Assumed
1/3 of all cabs must be
enclosed.

Some farms may incur costs
due to Underground Storage
Tank regulations/ however,
due to the significant
amount of uncertainty as to
whether specialty crop farms
would have covered UST's.
These costs were not included.

           Lead Phasedown
Under a total ban of lead
in gasoline for agricultural
use, farmers having gasoline
powered tractors, combines,
and trucks may incur a cost
to rebuild the valves.
This cost would be approxi-
mately $1,000 for a combine
and a truck, and $750 for a
tractor. These costs were
not included in the budget
analyses for tomato producers.

                  Data Problems and Assumptions


The agricultural sector study relied on a wide range of information
sources of varying quality.  This section summarizes the data
sources and briefly discusses the limitations of the data.


              1.0   Basic  Crop Production  Information

Basic crop production data was obtained from annual publications
of the USDA National Agricultural Statistics Service (NASS) where
data were available.  For apples and caneberries there was not a
consistent data source.  Production and price information for
apples was obtained from USDA, while information on acres harvested
was obtained from the Bureau of Census.  Different estimation
techniques were used in these two sources and they were collected
in different time periods.  However,  apples are a relatively slow
growing perennial crop, so differences in time frames of a few
years are probably not particularly important.  There were limited
caneberry data available in statistical publications from some
important states.  The production data sources used in this study
are listed below.

     A.   Crop Production, Annual Summary for relevant years,
          National Agricultural Statistics Board, USDA.

     B.   Vegetables, Annual Summary for relevant years, National
          Agricultural Statistics Board, USDA.

     C.   1982 Census of Agriculture, Bureau of Census, USDC.

     D.   Non Citrus Fruits and Nuts, Annual Summary for relevant
          years, National Agricultural Statistics Board, USDA.

     E.   Various state annual reports of agricultural statistics
          for relevant years.


                   2.0  Time Frames for Actions

We attempted to project the year in which actions might take
place and, for past actions, relied on historical information as
to when actions actually occurred.  Projections for future actions
were based on an examination of likely dates for actions to take
place.

For all pesticide specific actions we projected that impacts
would dissipate evenly over a seven year period as users adjusted
their practices and new pest control products became available.

                               F-l

-------
There is some question regarding the accuracy of this assumption.
Clearly, if new technologies exist to ameliorate the impacts of a
regulatory action, they would tend to be registered (if necessary
and they meet the criteria) and adopted within a seven year
period.  In addition, the cancellation of a pesticide would
create some incentive to replace it.  However, there is no
certainty that such new technologies exist or if they do not
currently exist, would be developed, registered, marketed, and
adopted within a seven year time frame.  The incentive to develop
and market new technologies would tend to be greater for the
major field crops, where large potential markets exist.  There
are also some data which suggest that new pesticides would be
more expensive than older ones which have been cancelled.


                    3.0  Pesticide Usage Data

Quality of pesticide usage data vary widely.  There are adequate
regional (multi state) level usage data for most major field
crops (corn, cotton, sorghum, wheat, and soybeans).  Pesticide
usage data for barley, oats, and hay are sporadic,  with the most
recent data being from the 1970's.  Therefore, usage estimates
developed by the registrants were used for these crops.  In
general, the usage data bases for major field crops are designed
to be statistically reliable at the 10 percent level for the
sample region.  USDA has on occasion, collected statistically
reliable state level data for selected major field crops in
selected states.

Specialty crop pesticide usage data are highly erratic.  USDA
last collected pesticide usage data for tomatoes, green peas,
apples, and potatoes in the 1970's.  Latest USDA peanut pesticide
usage data are for 1982 and there are no data for caneberries.
State collected pesticide usage data were utilized when available.
However, there are no regular periodic state usage surveys.
California collects and reports all pesticide usage for restricted
use materials and commercial applicators.  This results in usage
data which should be very reliable for restricted use materials;
but are of questionable usefulness for unrestricted use materials.

The Pesticide Program has access to some proprietary pesticide
usage estimates for major field crops and selected specialty
crops.  However, the reliability of these estimates is largely
unknown.  For major pesticides on major crops, these estimates
agree with available data collected in statistically designed
surveys.  However, for minor pesticides and specialty crops, usage
estimates obtained from proprietary sources are often inconsistent
with available statistically designed surveys.

Analysis of the proposed pesticides in groundwater actions required
projections of pesticide use at the county level.  However, there
are no public data collected to be statistically reliable at the

                               F-2

-------
county level.  Data provided by a contractor was used to predict
pesticide usage at the county level.  However, this data base is
composed of information drawn from available reports and expert
opinion or local Cooperative Extension Service personnel and 'is not
based on a statistically valid sample.  The Federal government
does not have data to check the reliability of any of these
estimates.
   4.0  Comparative Efficacy and Costs of Alternative Controls

Inputs developed and cleared by the program offices were used
for past and near actions.  The rigor of these analyses varied
considerably.  In some instances, potential yield impacts were
not investigated and a zero yield loss was assumed.  In other
situations, rigorous analyses of the magnitude of possible yield
losses were available.

In general, available pesticide crop trials are not designed to
generate statistically reliable estimates of the differences in
yields among substitute chemicals.  The objective of the crop
trials is to demonstrate that the pesticide provides some control
of the pest and not to reveal how pesticides compare with each
other.

For actions expected to take place further in the future (generally
beyond about one year), various sources of information were
employed.  The following reports generated by, or for, and cleared
by the program offices were used:

     Preliminary Benefit Analysis of Toxaphene

4.1  Corn and Soybeans

Publications from the USDA Commodity Assessment of Pesticide Use
on Corn and Soybeans and Potential Bans of Corn and Soybean
Pesticides, by Craig Osteen and Fred Kuchler USDA, ERS, Agricul-
tural Economic Report Number 546 as well as some unpublished
supporting commodity assessment data information (made available
by the USDA) provided comparative efficacy for corn and soybeans.
This provided a consistent data base which appears reasonable for
the actions proposed for the future.  The commodity assessment data
base was constructed by obtaining expert opinion of estimates of
product cost and yield effects due to losses of pesticides.  The
USDA has not updated this report and the estimates are somewhat
dated.  In some cases, the cost of alternatives provided in the
Commodity Assessment was not appropriate for this analysis.  In
these cases the Commodity Assessment was supplemented with
information from the Economic Analysis Branch (EAB) price files.
Efficacy data for corn and soybeans is probably the most reliable
of all crops considered in this analysis.

Concerns about groundwater contamination were assumed to result
in the cancellation of both alachlor and the triazines in selected
areas.  In reality alachlor and the triazines are partial sub-
stitutes; however, the Commodity Assessment never considered the
question of the loss of both alachlor and the triazines.  In the
absence of any information on how production costs and yields would
change under the cancellation of both alachlor and the triazines,
we used the commodity assessment data, which indicate the efficacy
information associated with the cancellation of each one, assuming
the other remains on the market.  Logic indicates that the simple
addition of impacts probably underestimated the impact of cancel-
ling both, but the degree of underestimation is unknown.
                               F-4

-------
4.2  Remaining Major Field Crops (Wheat/ Cotton, Sorghum, Barley,
     Oats, Hay)

4.2.1  Wheat, Barley, Oats

There was only one significant future action that affected wheat.
Yield change estimates developed for EPA by the registrants were
used.  There was no significant Agency review of these estimates
(Benefits Estimates for Maneb, Pennwalt Corporation, December
1987 & Response of the Rohm and Haas Company to the Special
Review for EBDC Fungicides, Rohm and Haas Company, October 1987).

4.2.2  Cotton

EPA policy actions assumed in this analysis have potentially
significant affects on cotton production.  Estimates of impacts
were developed rather rapidly using judgments of EAB staff members
Possible actions are in areas where a number of alternative
controls exist.  Therefore, it is likely that the estimates
developed are reasonable.

4.2.3  Sorghum

No efficacy data were available for sorghum.  For herbicides it
was assumed that the cost and percent yield changes would be the
same as those for corn since the crops, pesticides, and pest
spectra are similar.  This could be a significant limitation
since sorghum tends to be grown in drier and warmer areas than
corn.  The actual performance of the herbicides could be different
under these conditions.  The impacts of other actions were
developed internally based on judgement.  Other pesticides are
of limited importance in the production of sorghum, therefore,
our estimates are probably within reason even though not well
documented.

4.2.4  Hay

Possible actions were very limited.  Only a small portion of the
acres planted are impacted (less than one percent).

4.3  Specialty Crops

4.3.1  Peanuts

Most information for impact estimates for alachlor and aldicarb
(groundwater) were available from reports previously cleared by
the program office (see above).  We estimated portions of acres
that would be affected based on knowledge of the soils where the
crop is grown. Industry estimates of fungicide cost and yield
impacts were used, although they had not been subject to internal
review. Insecticide cost and yield effects were developed intern-
ally based on information on alternatives and possible target

                               F-5

-------
pests.  Although we feel reasonably comfortable with estimates
for the individual actions/ we feel very uncomfortable with the
simple addition as a means of aggregating yield impacts across
chemicals.  This problem, in addition to lack of information on
supply elasticities for peanuts, prevented us from providing a
complete analysis of the impact of EPA actions on peanut growers.

4.3.2  Apples

Cost and yield impact information provided by industry was utilized
for fungicides.  Cost information for other pesticides used on
apples was estimated internally based on knowledge of registered
materials and labeled target pests.  Yield impacts were estimated
internally based on limited information on yield impacts from
selected pesticides.

4.3.3  Potatoes

Aldicarb (pesticide- in groundwater) information was available
from an existing Agency study.  Fungicide information was available
from an industry report submitted to the Agency.  Remaining impacts
were estimated internally as they were for apples.

4.3.4 'Green Peas and Tomatoes

Pesticide industry estimates were available for fungicides.
Only limited information (primarily materials registered and
target pests) was available to estimate cost and yield impacts
associated with other future actions.  We had some limited
estimates from a contract publication (with no knowledge of how
these estimates were obtained) on most common target pests and
usage of various materials.  Yield and cost impacts were estimated
internally with little or no foundation, other than past experience
on larger crops.

4.3.5  Caneberries

Virtually no information was available except for pesticide
registrations and target pests on labels.  This was the situation
for most past actions as well as possible future actions.  The
following informational reports were used:

     Abbreviated Benefit Analysis of Dinoseb (Since the dinoseb
     action was still in litigation at the time inputs were
     developed for the study, estimates of impacts as developed
     for the regulatory action were used for this analysis).

                        5.0  Elasticities

Price elasticities used for the major field crops were those
contained within the simulation model (AGSIM).  While the estimated
elasticities may be subject to criticism, they were generated in
a consistent manner within the same model.  Price elasticities
for the specialty crops were short-run farm level elasticities
and were obtained from whatever reasonable sources were available.
These estimates of supply and demand elasticities may have been
estimated from different data bases using different techniques.

5.1  Apples

Obtained elasticities of supply from a USDA/ERS report "An
Econometric Model of the U.S. Apple Market," June 1985.  Elasticity
of demand estimates from K. Huang, USDA/ERS, 1985.

5.2  Caneberries

Estimates of elasticities were not found.

5.3  Peanuts

Discussions with economists familiar with peanut production
(both with USDA and in major peanut production areas) indicated
that there are no reasonably reliable peanut elasticity of supply
estimates available.  Elasticities of demand are from K. Huang,
USDA/ERS.  However, these are questionable due to the nature of
perceived demand for domestic peanuts produced under quota and
additional peanuts (peanuts for export and oil).

5.4  Peas, Potatoes and Tomatoes

Elasticities of demand were obtained from K. Huang, USDA/ERS,
1985. Elasticities of supply for peas were obtained from Ascari and
Gummings, International Economic Review, 1977.  Elasticity of
supply for potatoes was obtained from unpublished work by G.
Zepp, USDA/ERS, 1987.  Elasticity of supply for tomatoes was
obtained from Churn and Just, Giannini Monograph, 1978.

             Cumulative  Probability Cost Distribution

Since we are simultaneously examining the impact of several EPA
policies, a fundamental issue that had to be determined was:
how do we define an "impacted" farmer?  For example, Illinois
corn soybean farmers may be affected by the cancellation of several
different pesticides, may incur insurance costs if they have an
underground storage tank that meets certain criteria,  and may
incur an expense to rebuild their tractor engine if all lead is
banned from gasoline and they have a leaded gasoline tractor.
How many of these potential costs do we assume that the "impacted"
farmer incurs?  For each producer we examine two alternative sets
of impacts:

     *    A Maximum Impact Case;  In this case it is assumed that
          the producer is affected by every regulation that may
          possibly affect a producer of that type.

     *    An Average Impact Case;  In this case it is  assumed
          that the producer experiences the average impact of
          producers of that type - e.g.,  if 10% of all producers
          of a given type experienced a cost of $1,000, we would
          use a cost of $100 ($1,000 x 0.10) for the average
          impact case.

Examining these two cases, however, only provides two  snapshots
of possible impacts without providing the full picture of how
cost and yield impacts are likely to be distributed across
producers.  To provide more insight into the likely distribution
of these initial cost and yield impacts,  we constructed a cumula-
tive probability cost curve for each representative farm in
average financial position.  The following example demonstrates
what these cumulative probability cost curves reveal.

Suppose a given farmer may be affected by three possible regula-
tions, each having the following associated cost and probability
of affecting a given producer:

                              Probability    Probability
     Regulation     Cost      of Impact      of No Impact
          A         $100           .30            .70
          B         $200           .20            .80
          C         $300           .10            .90

Provided the probabilities of incurring the costs of the three
regulations are independent, the possible set of outcomes and
associated costs and probabilities may be defined as:
                               G-l

I/   Note  the  probability of being impacted by Regulation A  =
     P(A)  x P(NB)  x  P(NC),  where P(A) = the probability of being
     affected  by  regulation A,  and P(NB), P(NC) = the probability
     of not being  affected by B and C, respectively.

By ranking these  possible outcomes in order of cost, and adding
up the associated  probabilities, we can arrive at the following
cumulative probabilities:
     Regulations
     Affected  by;
        NONE
          A

Then, plotting  the  cost  on the x-axis and the cumulative probabil-
ity on the y-axis,  we can use this information to generate  the

than or equal to a given level.  For example, it indicates that
any given farmer has a probability of .846 of incurring a cost
that is less than or equal to $200.

To shed insight into the probability that the farms examined in
this report would actually incur any given level of cost, we
generated a cumulative probability cost curve for each of the
representative farms in average financial position.  In the above
example, all of the costs were assumed to be independent.  In
reality, however, this may not be the case.  For example, farmers
who use a certain type of pesticide on their corn may very likely
be using the same pesticide on their soybeans, if the pesticide
is used on a certain pest that is found on both corn and soybeans.
In generating the cumulative probability cost curve for each
representative farm, we tried to account for the correlation
among different costs.  The assumptions we used for each represen-
tative farm are outlined below:

Illinois corn soybean farm assumptions:

     1.   If a farmer is using any chemical, then he incurs Farm
          Worker Safety Costs.
     2.   If a farmer is using alachlor on his soybeans, then he
          is using alachlor on his corn.
     3.   If a farmer is using a corn rootworm insecticide on his
          corn, then he is using a triazine on his corn.
     4.   If a farmer is using alachlor on his corn, then he is
          using a triazine on his corn.

Mississippi cotton soybean farm assumptions:

     1.   If a farmer is using any chemical, then he incurs Farm
          Worker Safety Costs.
     2.   If a farmer is using dinoseb on his soybeans, then he
          is using dinoseb on his corn.

Kansas wheat cattle farm assumptions:

     1.   If a farmer is using any chemical, then he incurs Farm
          Worker Safety Costs.
     2.   If a farmer is using alachlor on his soybeans, then he
          is using alachlor on his corn.
     3.   If a farmer is using a triazine on his corn, then he is
          using a triazine on his sorghum.
     4.   If a farmer is using alachlor on his corn, then he is
          using a triazine on his corn.

Incorporating these assumptions into the method described in the
above example, we generated a cumulative probability cost curve
for each representative farm in each scenario (Figures G-l through
G-5).  Any given point on the curve may be interpreted as the

probability that the representative farm will incur a cost equal
to or less than a given level.  For example, the curve in Figure
G-la indicates that the representative Illinois corn soybean farm
in Scenario 1 has a .50 probability of incurring a discounted
present value of cost and yield impacts (1987-1996) of less than
or equal to $2", 000.  The discounted present value of cost and
yield impacts corresponding to the average and maximum impact
cases are indicated on each curve.

If all Illinois corn soybean farms had the same number of acres
of each crop as the representative farm, Figure G-la could be
interpreted as the percent of farms likely to incur cost and
yield impacts less than or equal to a given level.  Since farms
will vary in the number of crop acres that they plant, their
present discounted value of impacts under any particular combina-
tion of regulations will vary from the representative farm.
(Recall that the representative farm does not truly represent all
farms but is only a composite of farms of a given type.)  These
curves, therefore, are only meant to provide some insight into
the distribution of cost and yield impacts for farms of a given
type, but do not represent accurate cost and yield impacts for
any particular farm (other than the average farm), or the true
distribution of impacts across farms.

    Recommendations for Acquiring Better Pesticide Usage Data

In this agricultural sector study, the lack of current and reliable
pesticide usage data has limited the ability to accurately assess
the economic impact of EPA actions, particularly on the specialty
crops.  The quality of the usage data used in the report is
described in Appendix F.  To summarize, data for the major crops
were usually adequate only at the regional level.  For small-area
crops, the data were old and/or of unknown statistical validity.
For no crop was information available nationwide at the county
level which is the minimum level of disaggregation needed for
measuring the impact of ground water regulatory actions.  The
gaps identified in Appendix F could affect the study results
because the measurement of economic impacts of EPA actions depends
on the cost and yield effects of pesticide cancellation which in
turn depend on usage data.

The agricultural sector study is only one example of the many EPA
analyses that depend on basic pesticide data for accurate estima-
tion of economic and other effects of pesticide regulation.
Because this study is an excellent illustration of the difficulty
the data limitations present, it is an opportunity to discuss
those limitations, their consequences for economic and risk
analyses of pesticide use, and what can be done to improve the
situation.

As seen in the agricultural sector study, two types of basic
pesticide data are fundamental to assessing a pesticide's economic
importance: performance and usage.  A current project in the
Office of Pesticide Programs directly addresses the incompleteness
of the performance data by strengthening data requirements placed
on pesticide manufacturers.  For that reason, the discussion here
is limited to usage data, defined roughly as the amount a par-
ticular pesticide and its alternatives are used on a crop, how
many acres are treated with each pesticide, in which locations, at
what rate, and by what methods. For the sake of brevity, the
focus is on agricultural pesticide use, although data problems
exist with nonagricultural use as well.


           1.0  Why Pesticide Usage Data are Important

The agricultural sector study is just one of several recent
special analyses relying on pesticide usage data.  Some of the
special studies could be of far-reaching importance for future
pesticide use, for example, preparation for the Agency's En-
dangered Species Program and targeting of water wells for the
national groundwater monitoring program.  For risk/benefit analyses
on individual pesticides and for other regular pesticide assess-
ments (e.g., exemptions for local use), usage data and performance
data form the foundation upon which scientists and economists
build their quantitative estimates of a pesticide's importance.

Without complete information, often the case with small area
crops, analysts must rely on educated guesses, adding uncertainty
to their final conclusions.  In the recent case of the herbicide
dinoseb, usage information on alternatives was not readily
available and analysts had inadequate time to gather it.  This
lack of data contributed to a successful legal challenge by
growers of some small crops, causing EPA to exempt those crops
from the suspension decision already made.  Furthermore, usage
data are an integral part of exposure assessments, which in turn
play a key role in deciding whether a pesticide is placed in
Special Review.


                 2.0  Current  State of  Usage  Data

The agricultural pesticide usage data currently available are
very uneven in quality and coverage.  For the major crops such as
corn, soybeans, cotton, and wheat, current survey data are
available from USDA and private sources and are likely to be
collected periodically in the foreseeable future.  Information on
major crops falls short of OPP's needs because it often excludes
minor producing areas and are often not disaggregated to a small
enough geographic level.  Considerably greater problems occur
with small-area crops,  for example, there has been .no publicly-
available survey of pesticide use on citrus since 1977.  For the
specialty crops studied in this report as well as the whole
spectrum of fruits, vegetables, and other crops, usage data are
rarely what they need to be: current, reliable, disaggregated at
least to the state level, and publicly available.


          3.0   Recommendations  for  Acquiring  Better  Data

The Benefits and Use Division (BUD) of the Office of Pesticide
Programs has made a concerted effort to upgrade its usage data,
but is often met with budgetary constraints.   BUD recently
estimated that it would cost $3 million to acquire adequate
survey usage data on crops and nonagricultural sites of importance
to OPP. That expenditure would be needed every three or five years.

However, the Office of Pesticide Programs is not the only organi-
zation needing pesticide usage data, and the list is growing
because of heightened concern about pesticide health and environ-
mental effects, for example groundwater contamination.  Other
organizations which recently used pesticide usage data are:

            Department of Agriculture,
            EPA Office of Drinking Water, Non-Point Source Branch,
            EPA Office of Ground Water Protection,
            individual registrants,
            Food and Drug Administration,
            National Agricultural Chemicals Association,

          * state environmental, water quality, and public health
            programs, and
          * U.S. Geological Service, Water Resources Division.

For some of the options that follow, a cost-sharing arrangement
between EPA an~d~other interested organizations could make the
data acquisition far more affordable.

Below are possible options for generating better pesticide usage
data. Each has different costs and benefits.

     1.   Conduct a set of jointly-funded periodic surveys of
          pesticide users

          Each set would cover certain sites, such as major
          crops, small area crops, crops in certain regions,
          pesticide-intensive crops in areas of groundwater
          vulnerability, or nonagricultural sites. A different
          group of sponsoring organizations would fund each set.
          Fees would be charged to non-sponsoring users.

     2.   Set up cost-sharing between EPA and states to conduct
          surveys

          This is a more limited version of option #1. In order
          to receive EPA funds, states would have to design the
          surveys to meet certain specifications so the data.
          would fit EPA's needs.  This might be the most efficient
          approach for small crops.

     3.   "Socialize" private data collection services
          These services currently poll farmers nationwide on
          pesticide usage.  EPA and other interested parties
          could contract to completely fund the data collection,
          in order to be able to control the survey methods and
          site coverage, and to ensure the data is public.

     4.   Attach questions to existing USDA surveys currently
          used for other purposes

          This is already being done to a limited extent; the
          new questions would be much more detailed.

     5.   Attach questions to the U.S. Census of Agriculture

          The Census currently asks farmers questions on all
          crops as well as usage of pesticide in broad categories.
          To be useful for most EPA analyses, additional questions
          would be added that are detailed at the active ingredient
          level.

     6.   Require data from registrants

          Registrants are required to generate pesticide toxicity
          and performance data to support pesticide registrations.
          If usage data were also required, the cost to the
          government would be lower than with other options,
          though there could be problems with confidentiality.

     7.   A combination of the above

          Existing USDA surveys cover only a subset of the crops
          relevant to EPA. Pesticide usage questions could be
          attached to those surveys while data on remaining
          crops could be collected jointly by a consortium as in
          #1 and #3.

An interagency committee composed of EPA, USDA, FDA, and DOI,
meets on occasion to share pesticide usage data.  To date, there
has been no joint funding of data.  Working through the committee,
the OPP Benefits and Use Division and the OPPE Office of Policy
Analysis have begun an initiative to acquire better data.


                           4.0   Summary

There is a clear need for more detailed, precise estimates of
pesticide usage, both agricultural and non-agricultural.  Recent
renewed interest in pesticide-related environmental and health
problems has increased the number of organizations needing such
information.  Because there are many hundreds of different
pesticidal active ingredients and hundreds of different crops and
nonagricultural sites across the country, acquiring high quality
information on a regular basis is expensive.  Yet without it, the
accuracy of economic valuation of pesticides is uncertain.  If
such accuracy is deemed important enough, some increased effort
will be needed to acquire the necessary data.

There are several ways to generate better usage data. Detailed
questions could be attached to existing surveys designed for other
purposes, EPA could require the data from registrants, or a consor-
tium of interested private, federal, and state organizations
could be formed to share the costs of new surveys.  Since there
is a wide variety of use sites, a different arrangement might be
made for different types of sites.

Each approach would differ from a cost-benefit standpoint.  To
the extent EPA can pool resources with other users of pesticide
data, costs can be lowered.  The benefit of better data will be
greater efficiency in the assessments of pesticide use, a higher
quality of analysis, and subsequently, more informed decisions on
pesticide regulation.
