                       I.  INTRODUCTION

              The Registration Standards Program

     EPA has established the Registration Standards program
in order to provide an orderly mechanism by which pesticide
products containing the same active ingredient can be reviewed
and standards set for compliance with PIPRA.  The standards
are applicable to reregistration and future applications for
registration of products containing the same active Ingredient.
Each registrant of a product containing an active ingredient
subject to this Standard who wishes to continue to sell or
distribute that product must bring his product and labeling
into compliance with FIFRA, as instructed by this Standard.
Pesticides have been grouped into use clusters and will be
reviewed on the basis of a ranking scheme giving higher
priority to (1) pesticides in clusters used on food and feed
crops; and (2) pesticides produced in large volumes.

     The Registration Standards program involves a thorough
review of the scientific data base underlying a pesticide's
registration.  The purpose of the Agency's review is to
reassess the potential hazards arising from the currently
registered uses of the pesticide; to determine the need for
additional data on health and environmental effects; and to
de'termine whether the pesticide meets the "no unreasonable
adverse effects" criteria of PIPRA.  In its review EPA identifies

     1.  Studies that are acceptable to support the data
requirements for the currently registered uses of the
pesticide.

     2.  Additional studies necessary to support continued
registration.  The additional studies may not have been
required when the product was initially registered or may be
needed to replace studies that are now considered Inadequate.

     3.  Labeling revisions needed to ensure that the product
is not misbranded and that the labeling is adequate to protect
man and the environment.

     The detailed scientific review, which is not contained
in this document, but is available upon request, focuses on
the pesticide active ingredient.  The scientific review
primarily discusses the Agency's evaluation of and conclusions
from available data in its files pertaining to the pesticide

-------
active ingredient.  However, during the review of these data
the Agency is also looking for potential hazards that may be
associated with the end use products that contain the active
ingredient.  The Agency will apply the provisions of this
Registration Standard to end use products if necessary to
protect man and the environment.

     EPA's reassessment results in the development of a
regulatory position, contained in this Registration Standard,
on the pesticide and each of its registered uses.  See
Section IV - Regulatory Position and Rationale.  Based on its
regulatory position, the Agency may prescribe a variety of
steps to be taken by registrants to maintain their registrations
in compliance with PIFRA.  These steps may include:

     1.  Submission of data in support of product registration;

     2.  Modification of product labels;

     3.  Modifications to the manufacturing process of the
pesticide to reduce the levels of impurities or contaminants;

     4.  Restriction of the use of the pesticide to certified
applicators or other specially trained individuals;

•  -,.   5. "'Modification of uses or formulation types; or

     6.  Specification of packaging limitations.

     Failure to comply with these requirements may result in
the issuance of a Notice of Intent to Cancel or a Notice of
Intent to Suspend (in the case of failure to submit data).

     In addition, in cases in which hazards to man or the
environment are identified, the Agency may initiate a special
review of the pesticide in accordance with *JO CFR Part 151*
to examine in depth the risks and benefits of use of the
pesticide.  If the Agency determines that the risks of the
pesticide's use outweigh the benefits of use, the Agency
may propose additional regulatory actions, such as cancellation
of uses of the pesticide which have been determined to cause
unreasonable adverse effects on the environment.

-------
     EPA has authority under the Data Call-in (DCI) provisions
of PIFRA sec. 3(c)(2)(B) to require that registrants submit
data to answer our questions regarding the chemical, toxicological,
and environmental characteristics and fate of a pesticide.
This Registration Standard lists the data EPA believes are
necessary to resolve our concerns about this pesticide.
These data are listed in the Tables A and B in Appendix I.
Failure to comply with the DCI requirements enumerated in
this Registration Standard may result in issuance by EPA of a
Notice of Intent to Suspend the affected product registrations.

     Registrants are reminded that FIFRA sec. 6(a)(2) requires
them to submit factual information concerning possible unreason-
able adverse effects of a pesticide at any time that they
become aware of such information.  You should notify the
Agency of any information, including interim or preliminary
results of studies, if those results suggest possible adverse
effects on man or the environment.  This requirement continues
as long as your products are registered by the Agency.

            N- (2-methoxy-l-methylethyl) ace t amide
          Chemical Family:  Chloroacetanllide
          CAS Number:  51218-U5-2
          OPP (Shaughnessy) Number:  108801
          Empirical Formula:  CicjHjpClNC^
          Trade Names:  Dual, CGA-24705; Ontrack, Pennant
          Physical characteristics:  White to tan; Liquid; M.W. :
            238.8; Boiling Point:  100 °C at 0.001 mmHg;
            Odorless; Solubility:  530 ppm in water at 20 °C;
            Miscible with xylene, toluene, dimethyl formamide,
            methyl cellosolve, butyl cellosolve, ethylene
            dichlorlde, and cyclohexanone; insoluble in ethylene
            glycol and propylene glycol;  Vapor Pressure:
            about 10~5 mmHg at 20 °C.

      B.  .Use Profile

          Metolachlor is a selective herbicide registered
for the control of annual grasses and broadleaf weeds in
terrestrial crop areas including corn (field, sweet, and pop),
sorghum, cotton, potatoes, peanuts, soybeans, green beans,
kidney and other beans, blackeye and other peas, stone fruits,
and tree nuts; and terrestrial noncrop areas including ornamental
nursery plants and along railroads and highways.  Metolachlor
may be applied by conventional ground sprayer equipment and
incorporated before planting, or as a preemergence herbicide
applied during or after planting but before weeds or crops emerge.
Applications can also be made through center pivot irrigation
systems or by aircraft.  Metolachlor is in a class of herbicides
which are general growth inhibitors, especially of root elongation
It may also disrupt the integrity of plant cell membranes,
and inhibit lipid synthesis.

          Estimated total current amount of metolachlor applied
in the United States is 50,000,000 pounds of active ingredient
(ai) per year.  Agriculture accounts for 99 percent of the
usage.  The major use sites and percent of crop treated are
field corn (19%), soybeans (1155), sorghum (13%), and peanuts
          Metolachlor was first registered for use in 1976 and
is produced solely by Ciba-Geigy Corporation, Agricultural

-------
Division, Greensboro, North Carolina from active ingredient
manufactured outside the United States.  Metolachlor  is  available
as a Technical Grade Manufacturing-Use Product; an  86.^%  (ai)
Emulsifiable Concentrate; 5, 15, and 25% Granulars; 27.5?,
31.855, and 36.155 Plowable Concentrates with atrazine, a  36.3/6
Plowable Concentrate with propazine, and a 73.655 Emulsifiable
Concentrate with metribuzin.

                 III.  AGENCY ASSESSMENT

A.  Summary

          The Agency issued the orginal registration standard
for metolachlor in 1980. The data required by that standard
have been submitted and evaluated.  Because of changes in
the data requirements since 1980 and the finding of metolachlor
in surface and ground water, new data gaps have been identified.
Based on available data the Agency has reached the following
conclusions.  A detailed discussion of the points summarized
below appears in Section B.

          1.  Metolachlor chronic toxicity data indicate
weak evidence of oncogenicity, and is tenatively classified
as showing limited evidence of carcinogenicity in animals.

          2.  Metolachlor has been found in several surface
water surveys, some tap water samples, and in ground water in
two States.  Monitoring studies are required to determine the
extent of contamination on a national scale.

          As a result of this review, the Agency has identified
additional data necessary to evaluate the environmental and
humane-risks associated with the use of metolachlor.  These data
must be 'developed in order to maintain registration of products
or to register new products containing metolachlor.  A summary
of these data gaps appears in Table 1.  Please note that
this is only a summary and complete details can be obtained
by referring to the tables in Appendix I.

          The Agency has also determined that certain label
restrictions or revisions are necesary.  These include:

          Ground Water and Surface Water Advisory Statements
          Crop Rotation Restriction
          Endangered Species Precautionary Statements

          The Regulatory Position and Rationale Section
discusses the Agency's position on these restrictions and the
Required Labeling section contains the specific wording
required for each of the labeling revisions.

B.   Preliminary Risk Assessment

          Certain data gaps exist for raetolachlor  and  definitive
conclusions  cannot be made until the required  data are received.
The  following assessment Is based on the  data  available  and
is,  therefore, subject to change.

          1.  Chronic Peeding/Oncogenicity Data.   Metolachlor
is considered adequately tested for chronic  feeding and
oncogenic effects in laboratory animals.  It is considered an
oncogen  In rats but not in mice, as described  below.

              A 2-year chronic feeding/oncogenlcity study
with Sprague-Dawley rats was performed  at Industrial Biotest
Laboratories  (I3T).  Although validated,  the study is
supplementary because of several deficiencies  in protocol,
including dose levels which could not be  verified.   Conducted
at dietary doses of 0, 30, 300, and 3000  ppm,  the  study
had  a statistically significant increase  In  primary liver
neoplasms in  females of the high-dose group.

              A repeat chronic feeding/oncogenicity study In
Sprague-Dawley rats conducted at the same dietary  doses  as  •
the  original  study with 60 animals of each sex at  each dose
level had a  systemic NOEL of 30 ppm (1.5  mg/kg), a systemic
"LEL  o'f-:300 ppra {testicular atrophy), and  a statistically
significant  Increased Incidence of neoplastic  liver nodules
and  proliferative hepatic lesions in females of the high-do^se
group (3000  ppm).

              A valid IBT oncogenicity  study conducted with
Charles  River CD-I mice had no observed oncogenic  potential
at 30, 1000,  and 3000 (429 mg/kg).  A repeat oncogenicity
study with Charles River CD-I albino mice with 52  animals of
each sex and  at each dose level had no  observed oncogenic potential
at the same  dose level as the original  study.  A decrease in
body weight  gain at the highest dose tested  In males and
females  indicated that 3000 ppm was a Maximally Tolerated Dose.

          2.  Mutagenicity Data.  Available  mutagenicity
information  is negative.

              A bacterial (Salmonella)  system  (Ames Assay)
was  tested for base substitutions and point  mutations  at 10,
100, 1000 and 10,000 ug/plate and no increase  over background
mutation rates was observed.

              In a mouse dominant lethal  test  no effects were
noted on fertility rates, or on zygote  or embryo survivals,
after single  oral doses of 100 and 300  mg/kg.  No  malformations
of resulting  embryos were reported.  However,  additional
testing  is required because of the relative  Insensitivity of
the  test.
                                     8

-------
              Additional testing is required for in vitro
gene mutation in a mammalian cell system, chromosomal aberration,
and direct DNA damage.

          3.  Metabolism Data.  Animal metabolism testing  is
needed to satisfy current requirements.

          4.  Subchronic Feeding Data.  A 6-month subchronic
study was conducted with beagle dogs  in which equal numbers of
males and females were dosed with metolachlor at 0 (8/8),
100 (6/6), 300 (6/6), and 1000 (8/8) ppm in the diet.  Possible
compound-related effects consisted of a decreased gain in
body weight  in males and fema-les and a failure of the serum
alkaline phosphatase to decrease with increasing age in both
sexes.  The NOEL in the study was 100 ppm.  A reevaluation
of this study indicated statistically significant decreases
in activated partial thromboplastin time (APTT) in males and
females at 300 and 1000 ppm.  Rather than the reported error
in methodology, this may be a compound-related effect.
Therefore, a special study on effects of metolachlor on the
blood clotting system in the dog is required.  The requirement
for this additional study does not impact on the NOEL of 100
ppm which has been established from the subchronic study.

          5.  Reproduction and Teratology Data.  Metolachlor
i's considered to be adequately tested for teratogenic and
reproductive effects.  It is not considered to be either
teratogenic in rats or rabbits or to cause adverse reproductive
effects in rats,  as discussed below.

              A teratology study conducted with Sprague-Dawley
rats given oral doses of 0, 60, 180, or 360 mg/kg/day of
metolachlor did not affect the offspring.  The only possible
effect on the rats was a decrease in food consumption at the
highest dose during the first one-third of the experiment which
may indicate that this was the beginning of toxic maternal
doses.

              In a teratology study conducted with New Zealand
White rabbits given oral doses of 0, 36, 120, and 360 mg/kg/day
of metolachlor,  no evidence of compound-induced fetoxocity or
teratogenicity was observed.  Maternal toxicity was observed
at the high dose.

              In a two-generation reproduction study conducted
with Charles River rats given oral doses of 0, 30,  300, or
1000 ppm of metolachlor, no direct effects on reproduction
were shown including the highest dose.  The NOEL for reproductive
effects is 300 ppm based on reduced pup weights and reduced
parental food consumption at 1000 ppm.  Other effects that
may be related to treatment were increased liver to body

-------
weight and thyroid to body weight ratios in the 1000 pptn Fj
parents. The effects on pup weights at 1000 ppm can be considered
secondary to the reduced food consumption of the dams.

          6.  Oncogenic Risks:  The Agency has concluded that
the data available constitutes limited evidence of oncogenicity
under the EPA Proposed Guidelines for Carcinogen Risk Assessment
(November 23, 1984, 49 FR 46294). Therefore, metolachlor is
tentatively classified as a Category C carcinogen (limited evidence
of carcinogenicity in animals) for the reasons given below:

              a.  The oncogenic resonses observed with
                  metolachlor were confined solely to the
                  high dose females at one site (liver)
                  in Sprague-Dawley rats.

              b.  The proliferative liver lesions were primarily
                  benign (neoplastic nodules - 6 in 60 animals)
                  rather than hepatocellular carcinomas (1 in 60
                  animals).  There was no apparent difference
                  in the time-to-occurrence of the lesions
                  (almost all liver tumors were observed -at
                  terminal sacrifice).

              c.  Metolachlor is not oncogenic in Charles River
                  CD-I mice.

              d.  Metolachlor is not mutagenic in available
                  assays (an Ames test and a mouse dominant
                  lethal test).

              The Agency previously made a tentative risk
assessment based on the IBT rat oncogenicity study.  Assuming
a Q* = 2.1 x 10~3 (rag/kg/day)-I and using a Theoretical
Maximum Residue Contribution (TMRC) of 0.0755 mg/kg (1.5 kg diet),
the "worst case" dietary risk was calculated to be 3 incidences
in a million (3 x 10~°).  Using the TMRC provides a conservative
estimate since it does not consider the effect of processing
on residue levels in the raw agricultural commodity, that actual
residue levels may be lower than the established tolerance, and
that less than 100 percent of the crop is treated.

              Based on preliminary exposure estimates for use
of metolachlor on corn, and the Q* from the IBT rat study,
the following ranges in risk numbers were calculated:

              mixer/loader (farmer):  (10~7 - 10~8)
              mixer/loader (custom applicator):  (10~° - 10~7)
              applicator (farmer):  (10~5 - 10-°)
              custom applicator:  (10"1* - 10~5)
                                     10

-------
           7.   Ground  Water  and  Surface  Water  Contamination.
 Metolachlor  has  been  found  in several surface water  surveys.
 Transient  peaks  of  1.2  to 4.4 ppb  are reported in  river
 water  possibly as a result  of runoff during spring and summer.
 Detectable levels of  metolachlor were found in some  tap  water
 samples.   Metolachlor has the potential to leach and has
 been found in  ground  water  in two  States.  Since the extent
 of  contamination is unknown on  a national scale, monitoring
 studies  are  required.   A ground water advisory statement
 will be  required on the label.

 C.  Other  Science Findings

           Environmental Pate.   Available environmental fate
 studies  provide  only  limited information.  Although  the
 Metolachlor  Registration Standard  issued in September 1980
 discusses  certain studies,  the  previously submitted  data
 are not  adequate by current standards and procedures.

           Ecological  Effects.   Data  indicate  that  metolachlor
 is  practically nontoxic to  birds.  It is slightly  toxic  to
 aquatic  invertebrates,  and  moderately toxic to fish.

-D.  Tolerance  Reassessment

           Tolerances  have been  established for residues  of
 metolachlor  and  its metabolites in raw  agricultural  commodities,
 milk,  eggs,  meat, fat,  and  meat byproducts (mbyp)  [40 CFR
 §l80.368(a)] as  follows:

          Canadian tolerances of 0.1 ppm have been established
for residues of raetolachlor in or on beans, corn, peas,
potatoes and soybeans.  No Mexican tolerances or Codex
Alimentarius Commission Maximum Residue Limits have been
established for residues of metolachlor.
                                  13

-------
           EPA has evaluated the residue and toxicology  data
 supporting these tolerances and reviewed all uses  of  metolachlonJ
 Based on available data,  the following  conclusions have been
 made regarding residues of  metolachlor:

           o  The metabolism of  metolachlor  in root crops  is
              not adequately understood.   A  potato  metabolism
              study is required.

           o  Storage  stability  data are  required.

           o  Processing studies ar° required for potatoes,
              soybeans, field  corn, cottonseed, and peanuts.

           o  Residue  data are required  for  succulent  and  dried
              beans treated  with  the 25%  granular formulation
              of metolachlor.

           o  The present  seed and pod vegetables commodity
              expression which includes  okra  is now obsolete.
              40 CFR SlB0.368(a)  will  be  editorially corrected to
              read beans (succulent and dry)  and peas  (succulent
              and dry).

           o  All other tolerances are supported with  adequate
              residue  data.

           Pending receipt of  the additional studies,  the
 Agency  will evaluate  new  uses and new tolerances on a case-by-
 case basis.  If the incremental  risks are not significant the
 Agency  will continue  to establish new tolerances.   However,
 the  Agency does not intend  to establish  food additive tolerances
 under Section 409 of  the  Federal Food, Drug  and Cosmetic Act due
 to the  Delaney Clause  which bars establishment of  food additive
 regulations  for  substances which induce cancer in man or test
 animals.   Comments  will be solicited on this  issue regarding
 metolachlor  and other pesticides which have  produced a positive
 oncogenic  response  in animal studies.

           The acceptable  daily intake  (ADI)  for metolachlor
 is based on  the  rat chronic feeding study with a NOEL of 30 ppm
 and a systemic LEL of  300  ppm (testicular atrophy).  Using
 the NOEL of  30 ppm  (1.5 mg/kg/day)  and a safety factor of 100,
 the ADI is  0.015 mg/kg/day,  and  the  maximum  permissible  intake
 (MPI) is 0.9 mg/day for a  60 kg  person.   The established
 tolerances result in a total theoretical maximum residue concen-
 tration (TMRC) of 0.0755 mg/day  (1.5 kg  diet) which corresponds
to 8.38 percent of the MPI for a 60  kg person.

         IV.   REGULATORY POSITION AND RATIONALE

A.  Regulatory Positions and Rationales

          Based on review and evaluation of all data available
on metol.achlor, the Agency has made the determinations below.
Refer to Section IV. D. for specific language for label
revisions.

          1.  None of the risk criteria listed in 40 CPR 154.7
for initiating a Special Review have been met.  Therefore,
metolachlor is not being placed in Special Review at this
t ime.

              Rationale;  After considering available toxicology
data, the Agency has determined that no reason exists for
placement of metolachlor in Special Review at this time.
Metolachlor has tentatively been classified as a Group C
carcinogen (limited evidence of carcinogenicity in animals) and
appears to pose minimal risk of causing cancer in humans.

          2.  The Agency does not intend to establish new
food additive regulations pursuant to Section 409 of the
Federal Pood, Drug, and Cosmetic Act (PFDCA)

 ''..."-:-;-       Rationale;  The Delaney Clause in Section 409
of the FPDCA bars the establishment of food additive regulations
for substances which induce cancer in man or test animals,
with exceptions that do not apply here.  Metolachlor has been
found to produce an oncogenic response in test animals.  The
Agency will be soliciting comments on Delaney Clause issues
regarding metolachlor and other pesticides or metabolites
which have produced positive oncogenic responses in chronic
animal studies.

          3.  The Agency will continue to approve new uses
for Section 3 or 24(c) registrations for metolachlor on a case-
by-case basis.

              Rationale;  While data gaps exist in the areas
of environmental fate, residue chemistry and toxicological
effects, these gaps do not preclude the Agency from determining
that a new use will not result in unreasonable adverse effects
to humans and the environment.  The Agency will review and where
appropriate may approve such applications for new uses of
metolachlor.
                                         \5

-------
           4.  The Agency is requiring monitoring studies for
ground water and surface water contamination.

               Rationale;  Metolachlor has been found in
several surface water surveys and in ground water in two
States.  Monitoring studies are required to assess on a
national scale the extent of contamination.

           5.  The Agency is requiring a ground water and a
surface water advisory statement to appear on all end-use
products with metolachlor.

               Rationale;  Metolachlor has been found in
surface and ground water apparently as a result of its
agricultural use.  The label advisory statements will
emphasize to users the need to exercise care when mixing and
applying metolachlor in order to limit the possibility of
leaching to ground water, and runoff to surface water.

           6.  The Agency will not require a restricted use
classification for metolachlor end use products.

               Rationale;  Metolachlor is not acutely toxic
(toxicity category III) when tested via dermal, inhalation,
•oral and occular routes in rats and rabbits.  Some liquid
•formulations containing metolachlor have been assigned
toxicity II on the -basis of more acutely toxic inert
ingredients.  Metolachlor therefore does not met the aoute
toxicity criteria (40 CPR 162.11) for a restricted use
classification.

           7.  The Agency is not requiring a reentry interval
for currently registered uses of metolachlor.

               Rationale;  Exposure of metolachlor to field
workers is not expected to be significant since metolachlor
is incorporated prior to planting or applied after planting
to bare ground well before growth of the crop would require
entry into the treated field.  Therefore, no reentry interval
is required.
                                         16

-------
            8.   The Agency is imposing labeling restrictions
 on rotational  crops.   The extent of the restrictions will be
 reconsidered when additional data are submitted and reviewed.

                Rationale;  The Agency lacks sufficient data at
 the present time to determine whether planting a crop without
 existing tolerances in metolachlor-treated soil would result
 in illegal residues.   Existing data indicates possible uptake
 into rotated crops.  A 12 month planting restriction will serve
 to protect the public from impermissible residues in food and
 feed during the time  necessary to generate and assess the data.

            9.   The Agency is requiring a full range of
 environmental  fate studies (see data tables in Appendix I).

                Rationale;  Available data are insufficient to
 fully assess the environmental fate and transport of metolachlor.
 Therefore, additional data are required.

           10.   The Agency is requiring the following studies
 to support existing tolerances in agricultural commodities:
 potato metabolism study;  storage stability data; processing
 studies for potatoes, soybeans, field corn, cottonseed and
 peanuts; residue data on  succulent and dried beans treated
-with the 25% granular metolachlor formulation.

                Rationale;  Metabolism in potatoes has not
 been adequately defined.   Storage stability has not been
 completely characterized.  Adequate data are not available to
 describe residues in  processed products.  Residue data are
 required with  the 25% granular product to assure that applica-
 tion will not  exceed  established tolerances in beans (dry and
 succulent) and peas (dry  and succulent).

           11.   The Agency is requiring label statements
 regarding endangered  species for all metolachlor products
 registered for crop uses.

                Rationale;  Since metolachlor is a herbicide
 and has crop use patterns that overlap Federally designated
 endangered plant habitats, label restrictions are needed to
 to afford protection  to these endangered species.
                                    17

-------
          12.  While data gaps are being filled, currently
registered manufacturing-use and end-use products containing
metolachlor as the sole active ingredient may be sold,
distributed, formulated, and used in the United States.
Registrants must provide or agree to develop additional data,
as specified in Tables A and B of the Data Appendix.  The
Agency will issue registrations for substantially similar
products and will consider new uses on a case-by-case basis.

               Rationale:  Under the Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA), the Agency may determine
not to cancel or withhold registration if data are missing or
are inadequate [see FIFRA sections 3(c)(2)(B) and 3(c)(7)].

               Issuance of this Standard provides a mechanism
for identifying data needs.  These data will be reviewed and
evaluated and the Agency will determine if the data will
affect the registration of metolachlor.
                                18

-------
 B.   Criteria for Registration

           To be  registered  or reregistered  under  this  Standard,
 products  must contain raetolachlor as  the  sole  active  ingredient,
 bear required labeling,  and conform to  the  product  composition,
 acute toxicity limits,  and  use pattern  requirements listed  in
 this section.

 C.   Acceptable Ranges and Limits

           1.  Product Composition Standard

               To be  registered or reregistered under  this
 Standard,  manufacturing-use products  (MP) must contain
 metolachlor as the sole  active ingredient.   Each  MP formulation
 proposed  for registration must be fully described with an
 appropriate certification of limits,  stating maximum  and
 minimum amounts  of the  active ingredient  and inert  ingredients
 which are present in products, as well  as impurities  found  at
 greater than 0.1 percent.

           2.  Acute  Toxicity Limits

               The Agency will consider  registration of
'technical  grade  and  manufacturing-use products containing
'metolachlor provided that the product labeling bears  appropriate
 precautionary statements for the  acute  toxicity category in
 which each product is placed.

           3.  Use Patterns

               To be  registered under  this Standard,
 manufacturing-use products  may be labeled for  formulation
 into end-use herbicide  products only  for  the commodities listed
 below. The Use Index lists  all registered uses, as  well as
 approved  maximum application rates and  frequencies.

               -  Terrestrial, nondomestic, food uses on:
                 beans (succulent  and  dry),  fresh  corn, grain
                 corn, cotton,  peanuts,  peas (succulent and
                 dry), chili peppers,  potatoes, safflower,
                 sorghum, soybeans, stone  fruits,  and  tree
                 nuts.

               -  Terrestrial, nondomestic, nonfood uses on:
                 ornamental  plants, highway  and railroad rights-
                 of-way.
                                  19

-------
D.  Required Labeling

          All manufacturing-use products (and end-use products,
if covered by Standard) must bear appropriate labeling as
specified in 40 CFR 162.10.  Appendix II contains information
on label requirements.

          No pesticide product containing metolachlor may be
released for shipment by the registrant after 12 months after
receipt of the Standard unless the product bears an amended
label which complies with the requirements of this Standard

          No pesticide product containing metolachlor may be
distributed, sold, offered for sale, held for sale, shipped,
delivered for shipment, or received and (having so received)
delivered or offered to be delivered by any person after
24 months after receipt of the Standard unless the product
bears an amended label which complies with the requirements
of this Standard

          In addition to the above, the following information
must appear on the labeling:

          •1.  Ingredients Statement

              The ingredient statement for each MP must list the
active ingredient as:

                   Metolachlor

          2.  Use Pattern Statements

              All manufacturing-use products must state that
they are intended for formulation into end-use herbicide products
for acceptable use patterns.  Labeling must specify sites, which
are listed in Use Patterns, Section IV.C.3.  However, no use
may be included on the label where the registrant fails to agree
to comply with the data requirements in Table A for that use
pattern.

          3.  Precautionary Statements

              Manufacturing-Use Products

                   Environmental Hazards

                  contaminate water by cleaning of equipment
                  or disposal of wastes.

              c.  Ground Water and Surface Water^Advisory

                  Metolachlor has been identified in limited
                  sampling of ground water and there is the
                  possibility that it may leach through the
                  soil to ground water, especially where
                  soils are coarse and ground water is near
                  the surface.  "Following application and
                  during rainfall events that cause runoff,
                  metolachlor may reach surface water bodies
                  including streams, rivers and reservoirs.

                  Care must be taken when using this product
                  to prevent back siphoning into wells, spills
                  or improper disposal of excess pesticide,
                  spray mixtures or rinsates.

                  Check valves or antisiphoning devices 'nu.st
                  be used on all mixing and/or irrigation

                      22

-------
            V.  PRODUCTS SUBJECT TO THIS STANDARD

     All products containing the pesticide identified in
Section II.A. are subject to certain requirements for data
submission or changes in composition, labeling or packaging
of the product.  The applicable requirements depend on whether
the product is a manufacturing or end use product and whether
the pesticide is the sole active ingredient or one of multiple
active ingredients.

    Products are subject to this Registration Standard as
follows:

A.  Manufacturing use products containing this pesticide as
the sole active ingredient are subject to: 1) The restrictions
upon use, composition, or packaging listed in Section IV;
2) The data requirements listed in Tables A and B; 3) The
labeling requirements specified for manufacturing-use products
in Section IV; 4) Administrative requirements (application
forme, Confidential Statement of Formula, data compensation
provisions) associated with reregistration.!

B.  End-use products containing this pesticide are subject to:
1) The labeling requirements specified for end-use products
in. Section IV; 2) If not eligible for the formulator's exemption,
the data requirements listed in Table A.2
1 Data requirements are listed in the Tables in Appendix I
of this Registration Standard.  The Guide to Tables in that
Appendix explains how to read the Tables.  Table A lists
generic data requirements applicable to all products containing
the pesticide subject to this Registration Standard.  Table
B lists product-specific data applicable to manufacturing-use
products.  The data in Tables A and B need not be submitted
by a producer who is eligible for the formulator's exemption.

2 If you purchase from another producer and use as the
source of your active ingredient only EPA-registered products,
you are eligible for the formulator's exemption for generic
data concerning that active ingredient (Table A) and product-
specific data for the registered manufacturing use product
you purchase (Table B).  Two circumstances nullify this
exemption:  1)  If you change sources of active ingredient to
an unregistered product, formulate your own active ingredient,
or acquire your active ingredient from a firm with ownership
in common with yours, you individually lose the exemption
and become subject to the data requirements in Table A.
2)  If no producer subject to the generic data requirements
in Table A agrees to submit the required data, all end use
producers lose the exemption, and become subject to those
data requirements.

                                      23

-------
       VI.  REQUIREMENT FOR SUBMISSION OF GENERIC DATA

     This portion of the Registration Standard is a notice
issued under the authority of FIFRA sec. 3(c)(2)(B).  It
refers to the data listed in Table A, which are required to
be submitted by registrants to maintain in effect the regis-
tration of products containing this active ingredient.3

A.  What are generic data?

     Generic data pertain to the properties or effects of a
particular active ingredient.  Such data are relevant to an
evaluation of all products containing that active ingredient
regardless of whether the product contains other ingredients.
(unless the product bears labeling that would make the data
requirement inapplicable).

     Generic data may also be data on a "typical formulation"
of a product.  "Typical formulation" testing is often required
for ecological effects studies and applies to all products
having that formulation type.  These are classed as generic
data, and are contained in Table A.

B.  Who must submit generic data?

     All current registrants are responsible for submitting
generic data in response to a data request under PIFRA sec.
3(c)(2)(B) (DCI Notice).  EPA has decided, however, not to
require a registrant who qualifies for the formulator's
exemption (PIFRA sec. 3(c)(2)(D) and § 152.85) to submit
generic data in response to a DCI notice if the registrant
who supplies the active ingredient in his product is complying
with the data request.

     If you are not now eligible for a forraulator's exemption,
you may qualify for one if you change your source of supply
to a registered source that does not share ownership in
common with your firm.  If you choose to change sources of
supply, the Confidential Statement of Formula must Identify
the new source(s) and you must submit a Pormulator's Exemption
Statement form.

     If you apply for a new registration for products containing
this active ingredient after the issuance of this Registration
Standard, you will be required to submit or cite generic
data relevant to the uses of your product if, at the time
3 Registrations granted after issuance of this Standard
will be conditioned upon submission or citation of the data
listed in this Registration Standard.

                                     24

-------
the application is submitted, the data have been submitted
to the Agency by current registrants.  If the required data
have not yet been submitted, any new registration will be
conditioned upon the new registrant's submission or citation
of the required data not later than the date upon which
current registrants of similar products are required to provide
such data.  See PIPRA sec. 3(c)(7)(A).  If you thereafter fail
to comply with the condition of that registration to provide
data, the registration may be cancelled (PIPRA sec. 6(e)).

C.  What generic data must be submitted?

     You may determine which generic data you must submit by
consulting Table A.  That table lists the generic data needed
to evaluate current uses of all products containing this
active Ingredient, the uses for which such data are required,
and the dates by which the data must be submitted to the
Agency.

D.  How to comply with PCI requirements.

     Within 90 days of your receipt of this Registration
Standard, you must submit to EPA a completed copy of the form
entitled "PIPRA Section 3(c)(2)(B) Summary Sheet" (EPA Form
8580-1,.. enclosed) for each of your products.  On that form
you must state which of the following six methods you will
use to comply with the DCI requirements:

     1.  You will submit the data, and either —

         (a) Submit the existing data that you believe will
         satisfy the data requirements, or

         (b) State that you will secure the data or have
         made a contract to have any necessary studies completed
         within the applicable time period.

     2.  You have entered into an agreement with one or more
registrants to Jointly develop (or share In the cost of
developing) the data, but will not be submitting the data
yourself.  If you use this method, you must state who will
submit the data on which you will rely.  You must also provide
EPA with documentary evidence that an agreement has been
formed which allows you to rely upon the data to be submitted.
Such evidence may be:  (1) your letter offering to Join in
an agreement and the other registrant's acceptance of your
offer, (2) a written statement by the parties that an agreement
exists, or (3) a written statement by the person who will be
submitting the data that you may rely upon its submission.
The Agency will also require adequate assurance that the
person whom you state will provide the data is taking appropriate
steps to secure it.  The agreement to produce the data need
not specify all of the terras of the final arrangement between
the parties or a mechanism to resolve the terms.

-------
     3.  You have attempted to enter into an agreement to
Jointly develop data, but no other registrant has accepted
your offer.  You request that EPA not suspend your registration
for non-compliance with the PCI.  EPA has determined that,
as a general policy, it will not suspend the registration of
a product when the registrant has in good faith sought and
continues to seek to enter into a data development/cost
sharing program, but the other registrants developing the
data have refused to accept its offer.  [If your offer is
accepted, you may qualify for Option 2 above by entering
into an agreement to supply the data.]

     In order to qualify for this method, you must:

     1.  File with EPA a completed "Certification of Attempt
to Enter into an Agreement with other Registrants for Develop-
ment of Data" (EPA Form 8580-6, enclosed).

     2.  Provide us with a copy of your offer to the other
registrant and proof of the other registrant's receipt of your
offer (such as a certified mail receipt).  Your offer must,
at a minimum, conta'ln the following language or its equivalent:

     [Your company name] offers to share in the burden of
 •- •  producing the data required pursuant to FIFRA sec.
     3(c)(2)(3) in the [name of active ingredient] Registration
     Standard upon terms to be agreed or failing agreement
     to be bound by binding arbitration as provided by FIFRA
     section 3(c)(2)(B)(iii).

The remainder of.your offer may not in any way attempt to
limit this commitment.  If the other registrant to whom your
offer is made does not accept your offer, and if the other
registrant informs us on a DCI Summary Sheet that he will
develop and submit the data required under the DCI, then you
may qualify for this option.  In order for you to avoid
suspension under this method, you may not later withdraw or
limit your offer to share in the burden of developing the
data.  In addition, the other registrant must fulfill its
commitment to develop and submit the data.

     H.  You request a waiver of the data requirement.  If
you believe that a data requirement does not (or should not)
apply to your product or its uses, you must provide EPA with
a statement of the reasons why you believe this is so.  Your
statement must address the specific composition or use factors
that lead you to believe that a requirement does not apply.
Since the Agency has carefully considered the composition and
uses of pesticide products In determining that a data require-
ment applies, EPA does not anticipate that many waivers will
be granted.  A request for waiver does not extend the time-
frames for developing required data, and if your waiver
request is denied, your registration may be suspended If you
fail to submit the data.


                                        26

-------
     5.  You request that EPA amend your registration by deleting
the uses for which the data are needed.  You are not required
to submit data for uses which are no longer on your label.

     6.  You request voluntary cancellation of the registration
of your product(s) for which the data are needed.


E.  Procedures for requesting a change in testing protocol.

     If you will generate the required data and plan to use
test procedures which deviate from (or are not specified in)
either EPA's Pesticide Assessment Guidelines or the Reports
of Expert Groups to the Chemicals Group, Organization for
Economic Cooperation and Development (OECD) Chemicals Testing
Programme, you must submit for EPA approval the protocols
you propose to use.

     You should submit your protocols before beginning testing
and await EPA approval, because the Agency will not ordinarily
accept as sufficient studies using unapproved protocols.
A request for protocol approval will not extend the timeframe
for submission of the data, nor will extensions generally be
given to conduct studies due to subraittal of inappropriate
protocols.
F.  Procedures for requesting extensions of time.

     If you think that you will need more time to generate
the data than is allowed by EPA's schedule, you may submit a
request for an extension of time.  Any request for a time
extension which is made as an initial response to a section
3(c)(2)(B) request notice must be submitted in writing to
the Product Manager listed at the end of this section and
must be made before the deadline for response.  Once dates
have been committed to and EPA has accepted these commitments,
any subsequent requests for a time extension must be submitted
in writing to the Office of Compliance Monitoring.

     EPA will view failure to request an extension before
the response deadline as a waiver of any future claim that
there was insufficient time to submit the data.  While EPA
considers your request, you must strive to meet the deadline
for submitting the data.

     The extension request should state the reasons why you
believe that an extension is necessary and the steps you
have taken to meet the testing deadline.  Time extensions
normally will not be granted due to problems with laboratory
capacity or adequacy of funding, since the Agency believes
that with proper planning these can be overcome.  Time extensions
may be considered when Joint data development is planned,
                                            27

-------
or when the Agency must approve a new or modified protocol
before the study can be begun.

     A request for an extension does not automatically extend
the timefrarne for submission of the data.  If EPA denies
your request for a time extension and you do not submit the
data as requested, EPA may begin proceedings to suspend the
registrations of your products.
G.  Existing stocks provision upon suspension or cancellation.

     The Agency has determined that if a registration is
suspended for failure to respond to a DCI request under
PIFRA sec. 3(c)(2)(B), an existing stocks provision is not
consistent with the Act.  Accordingly, the Agency does not
anticipate granting permission to sell or distribute existing
stocks of suspended product except in rare circumstances.
If you believe that your product will be suspended or cancelled
and that an existing stocks provision should be granted, you
have the burden of clearly demonstrating to EPA that granting
such permission would be consistent- with the Act.  The following
information must be included in any request for an existing
stocks provision:

.  ....   .l.vExplanation of why an existing stocks provision Is
     necessary, including a statement of the quantity of
     existing stocks and your estimate of the time required
     for their sale or distribution; and

     2.  Demonstration that such a provision would be consis-
     tent with the provisions of PIPRA.
                                       28

-------
   VII. REQUIREMENT FOR SUBMISSION OF PRODUCT-SPECIFIC DATA

     Under Its DCI authority, EPA has determined that certain
product-specific data are required to maintain your registrations
in effect.  Product-specific data are derived from testing
using a specific formulated product, and, unlike generic
data, generally support only the registration of that product.
All such data must be submitted by the dates specified in
this Registration Standard.

     If you have a manufacturing-use product, these data are
listed In Table B.  As noted earlier, the Agency has decided
that it will not routinely require product-specific data for
end use products at this time.

     In order to comply with the product specific data require-
ments, you must follow the same procedures as for generic data.
See Section VI.D, E, F, and G.  You should note, however, that
product chemistry data are required for every product, and the
only acceptable responses are options VI.D.I. (submit data)
or VI.D.6.(cancellation of registration).

     Failure to comply with the product-specific data require-
ments for your products will result In suspension of the
product's registration.
                                           29

-------
    VIII.  REQUIREMENT FOR SUBMISSION OF REVISED LABELING

     PIPRA requires each product to be labeled with accurate,
complete and sufficient instructions and precautions, reflecting
the Agency's assessment of the data supporting the product
and Its uses.  General labeling requirements are set out In
40 CVR 162.10 (see Appendix II - LABELING and SUMMARY).  In
addition, labeling requirements specific to products containing
this pesticide are specified In Section IV.D of this Registra-
tion Standard.  Applications submitted In response to this
notice must include draft labeling for Agency review.

     If you fail to submit revised labeling as required,
which complies with 40 CPR 162.10 and the specific instructions
in Section IV.D., EPA may seek to cancel or suspend the
registration of your product under PIFRA sec. 6(b)(l).
                                           30

DATA APPENDICES
               34

-------
                           TGUIDE-1

                       GUIDE TO TABLES

     Tables A, B, and C contain listings of data requirements
for the pesticides covered by this Registration Standard.

     Table A contains generic data requirements that apply to
     the pesticide in all products, including data requirements
     for which a "typical formulation" is the test substance.

     Table B contains product-specific data requirements that
     apply only to a manufacturing use product.

     Table C contains product-specific data requirements that
     apply only to an end use product.

     The data tables are generally organized according to the
following format:

1.  Data Requirement (Column 1).  The data requirements are
listed in the order in which they appear in 40 CFR Part 158.
The reference numbers accompanying each test refer to the
test protocols set out in the Pesticide Assessment Guidelines,
which are available from the National Technical Information
Service, 5285 Port Royal Road, Springfield, VA  22161.

2. . Test Substance (Column 2).  This column lists the composition
of the test substance required to be used for the test, as
follows:

     TGAI = Technical grade of the active ingredient
     PAI =  Pure active ingredient
     PAIRA = Pure active ingredient, radio labeled
     TEP =  Typical end use formulation
     MP =   Manufacturing use product
     EP =   End use product

Any other test substances, such as metabolites, will be
specifically named in Column 2 or in footnotes to the table.

3.  Use pattern (Column 3).  This column indicates the use
patterns to which the data requirement applies.  Use patterns
are the same as those given in 40 CFR Part 158.  The following
letter designations are used for the given use patterns:
     A = Terrestrial, food
     B = Terrestrial, non-food
     C = Aquatic, food
     D = Aquatic, non-food
     E = Greenhouse, food
     F = Greenhouse, non-food
     G = Forestry
     H = Domestic outdoor
     I = Indoor
Any other designations will be defined in a footnote to the table.
                                     35

-------
                           TGUIDfi-2

 4.   Does  EPA  have data?  (Column  4).  This column  indicates one
 of  three  answers:

      YES  -  EPA has data  in its files that completely satisfy
      this data requirement.  These data may be cited by
      other  registrants in accordance with data compensation
      requirements of Part 152, Subpart E.

      PARTIALLY - EPA has some data in its files,  but such data
      do not fully satisfy the data requirement.   In some cases,
      the  Agency may possess data on one of two required species,
      or may possess data on one.  test substance but not all.
      The  term may also indicate:  that the data available to
      EPA  are  incomplete.  In this case, when the  data are
      clarified, or additional details of the testing submitted
      by the original data submitter, the data may be determined
      to be  acceptable.   If this  is the case, a footnote to
      the  table will usually say  so.

      NO - EPA either possesses no data which are  sufficient
      to fulfill the data requirement, or the data which EPA
      does possess ara flawed scientifically in a  manner that
      cannot be remedied  by clarification or additional infor-
      mation.

-5.   Bibliographic citation (Column 5).  If the Agency has
 acceptable data in its files, this column lists the identifying
 number of each study.  This normally is the Master Record
 Identification (MRID) number, but may be a GS number if no
 MRID number has been assigned.   Refer to the Bibliography
 Appendices for a complete citation of the study.

 6.   Must  additional data be submitted? (Column 6).  This
 column indicates whether the data must be submitted to the
 Agency.   If column 3 indicates that the Agency already has
 data, this column will usually indicate NO.  If column 3
 indicates that the Agency has only partial data or no data,
 this  column will usually indicate YES.  In some cases, even
 though the Agency does not have  the data, EPA will not require
 its  submission because of the unique characteristics of the
 chemical; because data on another chemical can be used to
 fulfill the data requirement; or because the data requirement
 has  been waived or reserved.  Any such unusual situations
 will  be explained in a footnote  to the table.

 7.   Timeframe for submission (Column 7).  If column 5 requires
 that  data be  submitted,  this column indicates when the data
 are  to be submitted, based on the issuance date of the Regis-
 tration Standard.  The timeframes are those established either
 as a  result of a previous Data Call-in letter, or standardized
 timeframes established by PR Notice 85-5 (August  22, 1985).

 3.   Footnotes (at the end of each table).  Self-explanatory.

 NOTE:   All residue data  requested  in  this Standard must he accompanied by information on the duration and
        conditions of sample storage prior to residue analysis, and by data depicting the stability of
        metolachlor residues under  the conditions and for the time intervals specified, with the exception
        of  corn stored at 15 °C for up to 13 months.  Exaggerated application rates may he required to obtain
        detectable measurable weathered residues in or on raw agricultural commodities used for the processing
        studies.

     residues.  Residue identities nust be confirmed by a  method such as GT, HPLC and/or mass spectrometry.   Data
     must  also be presented that reflect the extraction efficiency of the solvent(s)  used to remove residues
     following application of metolachlor to living plants.
 3/   Data must be submitted depicting decline over time (longer than 13 months)  of levels of residues during
     storage of treated commodities,  under conditions (other  than frozen  storage at - 15 °C)  used  in  residue tests

     stability of metolachlor in animal products (tissues,  milk, and  eggs).   5^>iked samples  should be stored at
     subfreezing temperatures for intervals approximating the storage intervals associated with treated samples
     used  to determine the magnitude  of the residue.
 4/   If  food uses are sought on other members of this crop group, residue data will be required for carrot,  radish,
~    and sugar beets.
 5/   Data must be submitted depicting residues of  concern in granules, chips, and dried  potatoes processed from
~~    potato tubers bearing measurable weathered residues.

     Item  8A.   HAZARD TO  HUMANS AND DOMESTIC  ANIMALS - Where a
 hazard  exists  to  humans  or domestic  animals,  precautionary
 statements are required  indicating the  particular hazard, the
 route(s)  of exposure and the  precautions  to  be  taken to avoid
 accident,  injury  or damage.   [40  CFR 162 ,10(h)(2)(i)]

     Item  8B.   ENVIRONMENTAL HAZARD - Where a  hazard exists to
 non-target organisms excluding humans and domestic animals,
 precautionary  statements are  required stating  the nature of
 the  hazard and the appropriate precautions to  avoid potential
 accident,  injury, or damage.   [40 CFR 162.10(h)(2)(ii)]

     Item  8C.   PHYSICAL OR CHEMICAL HAZARD -  FLAMMABILITY
 Precautionary  statements relating to flammability of a product
 are  required to appear on the label  if  it meets  the criteria
 in the  PHYS/CHEM  Labeling Appendix.  The requirement is
 based on  the results of  the flashpoint  determinations and
 flame extension tests required to be submitted  for all products.
 These statements  are to  be  located in the side/back panel
 precautionary  statements section, preceded by  the heading
 "Physical/Chemical Hazards."  Note that no signal word is
 used in conjunction with the  flammability statements.

     Item  9A.   RESTRICTED USE  CLASSIFICATION  -  FIFRA sec. 3(d)
•requir.e.s  that  all pesticide formulations/uses  be classified
 for'  either 'general or restricted use.   Products  classified
 for  restricted use may be limited to use by>  certified applicators
 or persons under  their direct supervision (or may be subject
 to other  restrictions that may be imposed by  regulation).

     In  the Registration  Standard, the Agency has (1) indicated
 certain formulations/uses are to be  restricted  (Section III
 indicates why  the product  has been classified for restricted
 use); or  (2) reserved any classification decision until
 appropriate data  are submitted.

    The Regulatory Position and Rationale states whether
 products containing this  active ingredient are classified
 for  restricted use.  If  they  are restricted  the  draft label(s)
 submitted to the Agency  as part of your application must
 reflect this determination  (see below).

     If you do not believe that your product should be classified
 for restricted use, you  must  submit  any information and
 rationale with your application for  reregistration.  During
 the Agency's review of your application, your proposed classi-
 fication determination will be evaluated in accordance with
 the provisions of 40 CFR 162.11(c).  You will be notified of
 the Agency's classification decision.

                           SUMMARY-4

      Classification  Labeling  Requirements

      If  your product has  been classified  for  restricted use,
 the  following label  requirements  apply:

      1.   All uses  restricted.

          a.   The statement "Restricted Use Pesticide" must
      appear  at  the top  of  the  front panel of  the label.  The
      statement  must  be  set in  type of the same minimum size
      as  required for human hazard signal word  (see table in 40
      CFR 162.10(h)(1)(iv)

          b.   Directly below this  statement on  the front panel,
      a summary  statement  of the terms of restriction must
      appear  (including  the reasons for restriction if specified
      in  Section I).   If use is restricted to  certified applicators,
      the following statement  is required:  "For retail sale
      to  and  use only by Certified Applicators  or persons
      under their direct supervision and only  for those uses
      covered by the  Certified  Applicator's Certification."

      2.   Some but  not all  uses restricted.  If the Regulatory
 position and Rationale  states  that some uses  are classified
 for  restricted  use,  and some  are  unclassified, several courses
•of action are available:

          a.  You may label the product for Restricted use.
      If  you  do  so, you  may include on the label uses that
      are unrestricted,  but you may not distinguish them
      on  the  label as being unrestricted.

          b.  You may delete  all  restricted uses from your
      label and  submit draft labeling bearing only unrestricted
      uses.

          c.  You may "split" your registration, i.e., register
      two separate products with identical formulations, one
      bearing only unrestricted uses, and the other bearing
      restricted uses.   To  do  so,  submit two applications for
      reregistration, each  containing all forms and necessary
      labels.  Both applications should be submitted simul-
      taneously.  Note that the products will be assigned
      separate registration numbers.

     Item 9B   [There  is  no  Item 9B].

     Item 9C.  MISUSE STATEMENT - All products must bear the
misuse statement, "It is  a violation of Federal law to use
this  product  in a manner  inconsistent with its labeling."
This  statement  appears  at  the beginning of the directions
for  use, directly beneath  the heading of that section.
                                       71

-------
                          SUMMARY-5

    Item 10A.  REENTRY STATEMENT - If a reentry interval
has been established by the Agency, it must be included on
the label.  Additional worker protection statements may be
required in accordance with PR Notice 83-2, March 29, 1983.

    Item 10B   [There is no Item 10B].

    Item IOC.  STORAGE AND DISPOSAL BLOCK -  All labels are
required to bear storage and disposal statements.  These
statements are developed for specific containers, sizes, and
chemical content.  These instructions must be grouped and
appear under the heading "Storage and Disposal" in the directions
for use.  This heading must be set in the same type sizes as
required for the child hazard warning.  Refer to Appendix II,
STOR, PEST/DIS, and CONT/DIS to determine the storage and
disposal instructions appropriate for your products.

    Item 10D.  DIRECTIONS FOR USE - Directions for use must
be stated in terms which can be easily read and understood by
the average person likely to use or to supervise the use of
the pesticide.  When followed, directions must be adequate to
protect the public from fraud and from personal injury and to
prevent unreasonable adverse effects on the environment.
[40 CFR 162.10]
                     COLLATERAL LABELING

    Bulletins, leaflets, circulars, brochures, data sheets,
flyers, or other written or graphic printed matter which is
referred to on the label or which is to accompany the product
are termed collateral labeling.  Such labeling may not bear
claims or representations that differ in substance from those
accepted in connection with registration of the product.  It
should be made part of the response.to this notice and submitted
for review.
                                      72

             STORAGE INSTRUCTIONS FOR PESTICIDES

Heading;

All products are required to bear specific label instructions
about storage and disposal.  Storage and disposal instructions
must be grouped together in the directions for use portion of
the label under the heading STORAGE AND DISPOSAL.  Products
intended solely for domestic use need not include the heading
"STORAGE AND DISPOSAL."

Storage Instructions;

All product labels are required to have appropriate storage
instructions.  Specific storage instructions are not prescribed.
Each registrant must develop his own storage instructions,
considering, when applicable, the following factors;

1.  Conditions of storage that might alter the composition or
    usefulness of the pesticide.  Examples could be temperature
    extremes, excessive moisture or humidity, heat, sunlight,
    friction, or contaminating substances .or media.

2.  Physical requirements of storage which might adversely
    affect the container of the product and its ability to
    continue to function properly.  Requirements might include
    positioning of the container in storage, storage or damage
    due to stacking, penetration of moisture, and ability to
    withstand shock or friction.

3.  Specifications for handling the pesticide container,
    including movement of container within the storage area,
    proper opening and closing procedures (particularly for
    opened containers), and measures to minimize exposure
    while opening or closing container.

4.  Instructions on what to do if the container is damaged in
    any way, or if the pesticide is leaking or has been
    spilled, and precautions to minimize exposure if damage occurs

5.  General precautions concerning locked storage, storage in
    original container only, and separation of pesticides
    during storage to prevent cross-contamination of other
    pesticides, fertilizer, food, and feed.

6.  General storage instructions for household products should
    emphasize storage in original container and placement in
    locked storage areas.

  ed by the phrase "EPA EsL". of the
  final establishment at which the prod-
  uct was produced may appear in any
  suitable location on the label or imme-
  diate container. It must appear on the
  wrapper or outside container of  the
  package if the EPA establishment reg-
  istration  number on the  immediate
  container  cannot  be  clearly read
  through such wrapper or container.
   (g)  Ingredient statement— <1) Gener-
  al The label of each pesticide product
  must bear a statement which contains
  the name  and percentage by weight of
 each  active  ingredient, the total per-
 centage by weight of all inert ingredi-
 ents;  and  if the pesticide contains ar-
 senic in any form, a statement of the
 percentages of total and water-soluble
 arsenic  calculated as  elemental  ar-
 senic. The active ingredients must be
 designated by the term "active ingredi-
 ents" and  the inert ingredients by the
 term ."inert ingredients," or the singu-
 lar forms of these terms when appro-
 priate. Both terms  shall be in the
 same type size, be aligned to the same
 margin and be equally prominent. The
 statement  "Inert Ingredients, none" is
 not required for pesticides which con-
 tain  100 percent active  ingredients.
 Unless the ingredient statement is a
 complete analysis of the pesticide, the
 term  "analysis" shall not be used as a
 heading for the ingredient statement.
  (2) Position of ingredient statement.
 (i)  The  Ingredient statement is nor-
 mally required on the front panel of
 the label.  If there Is an outside con-
 tainer or wrapper through which the
 ingredient statement cannot be clearly
      the frigrEKltent statement must
also appear on such outside container
or wrapper. If the size or form of the
package  makes it impracticable  to
place the ingredient statement on the
front panel of the label, permission
may  be  granted for the  ingredient
statement to appear elsewhere.
  (ii) The text of the Ingredient state-
ment must run parallel with other
text on the panel on which it appears,
and must  be clearly
 from and must  not be placed  in the
 body of other text.
   (3) Names to be used in ingredient
 statement. The name used for each in-
 gredient   shall   be  the  accepted
 common  name,  if  there  is one. fol-
 lowed  by the chemical  name. The
 common name may be used alone only
 if it is well known. If no common name
 has  been established,  the chemical
 name alone shall be used. In no case
 will the use of a trademark or proprie-
 tary name  be permitted unless such
 name has been accepted as a common
 name by  the Administrator under the
 authority of Section 2S(cX6).
  (4) Statements of percentages. The
 percentages  of ingredients shall  be
 stated  in terms  of  weight-to-weight. •
 The sum of percentages of the  active
 and the inert ingredients shall be 100.
 Percentages shall not be expressed by
 a range of values such as "22-25%." If
 the uses of the pesticide product are
 expressed as weight of active ingredi-
 ent per unit area, a statement of the
 weight of active ingredient per unit
 volume of the pesticide formulation
 shall also appear  in the  ingredient
 statement.
  (5) Accuracy of stated percentages.
 The percentages given shall be as pre-
 cise as  possible reflecting good manu-
 facturing  practice. If there may be un-
 avoidable variation between manufac-
 turing  batches, the  value stated for
 each active ingredient shall be the
 lowest  percentage  which  may be
 present.
  (6)  Dstcricrzticx.  Pesticides which
 change in chemical  composition sig-
 nificantly must meet the following la-
 beling requirements:
  (i) In cases where It-is determined
 that a  pesticide formulation changes
 chemical  composition   significantly.
 the product must bear the following
statement in a prominent position on
the label: "Not for sale or use after
 Cdatel."
  (ii) The  product must meet all label
rfflimg up to the expiration time indi-
cated on the labeL
  (7) Inert ingredient*.  The Adminis-
trator may require the name of any
Inert  Ingredlentfe) to be listed In the
Ingredient statement If he determines
that such ingredlentts) may pose a
hazard to man or the environment.

     (h)   Warnings  and  precautionary
   statements.  Required  warnings  and
   precautionary statements  concerning
   the  general  areas  of toxicological
   hazard including  hazard to children,
   environmental hazard, and  physical or
   chemical hazard fall into two groups;
   those required on the front panel of
   the labeling  and those which may
   appear  elsewhere.  Specific  require-
   ments concerning  content,  placement.
  type  size, and prominence  are given
  below.
   (1)  Required front panel statements.
  With  the  exception  of  the  child
  hazard warning statement, the text re-,
  quired on the front panel of the label
  is determined by the Toxicity  CategOr
  ry of  the pesticide. The category is as-
  signed on  the basis  of the  highest
  hazard shown by any of the indicators
  in the table below:

            GENERAL WARMINGS AND LIMITATIONS;  A selective herbicide recommended as a
            preplant surface-applied,  preplant incorporated, or preemergence treatment
            for controlling annual grasses and certain broadleaf weeds.  Dry weather
            following preemergence applications may reduce effectiveness.  Where a
            dosage range is given, use lower rate on coarse-textured soils or those
            low in organic matter; use higher rate on fine-textured soils or those
            high in organic matter.  Apply alone or in tank mixtures by ground equip-
            ment in a minimum of.10 gallons of spray mixture per acre unless otherwise
            specified.  Apply in water alone or in tank mixtures with listed herbi-
            cides in a minimum total volume of 2 gallons per acre by aircraft.

            PHYTOTOXICITY TO CROPS;  Injury may occur following use of product under
            abnormally high soil moisture conditions during early development of the
            •crop.

            MODE OF ACTION:  The chloracetamide herbicides are general growth inhibi-
            tors, especially of root elongation.  Metolachlor may disrupt the integri-
            ty of plant cell membranes, and inhibit lipid synthesis.

layby application.  Do not exceed 5.5 pounds ac-
tive ingredient per acre per season.
General Information;  Do not use on muck or peat
soils.  If cool, wet soil conditions occur after
application, maturity may be delayed and/or yield
reduced with Superior and other early maturing
varieties.  Do not apply both preemergence and
preplant or postplant incorporated treatments.
Do not use in Kern County, CA.

Preplaut or postplant incorporated.  Apply and in-
corporate into the top 3 inches of soil preplant,
or top 2 inches of soil postplant up to dragoff.
Do not damage potato seed pieces or sprouts with
incorporation equipment.  May be followed by a
preemergent application of metribuzin; or a layby
application of metolachlor (see use, below).

Preemergence.  The highest dosage is only used
when metolachlor is applied alone where soil or-
ganic matter is between 6 to 20 percent.

Preemergence.
Tank mix with metribuzin; or dinoseb; or with
linuron (east of the Rocky Mountains).

Postemergency.  Directed spray.  Apply up until
after the last hilling.
Tank mix with metribuzin.

Layby application.  Apply after hilling, at layby.
This may follow an earlier incorporated or pre-
emergence application of metolachlor, as long as
a total of 5.5 pounds active ingredient per acre
is not exceeded in a single crop season.

General Information;  If sorghum seed has not been
properly treated witn a safener such as N-(l,3-
dioxolan-2-yl-methoxy)-iminobenzene acetonitrile,
severe crop injury will result.  Under high soil
moisture conditions prior to sorghum emergence,
injury may occur following use of metolachlor.
The crop will normally outgrow this effect.  Do
not use on sorghum grown under dry mulch tillage
or crop injury may occur.  Under dry conditions,
irrigate after application.

Use limited to CO, IL, IA, KS, MO, NE, and SD.
Preplant.  Broadcast to soil surface in minimum-
tillage or no-tillage systems only.  May be ap-
plied up to 45 days before planting.  Use only
split applications for treatments made 30 to 45
days prior to planting with two-thirds of the rate
applied initially and the remaining one-third at
planting.  Treatments less than 30 days prior to
planting may be made either as a split or single
application.  Apply the lowest rate (for coarse
soils) not more than 2 weeks prior to planting.
May be formulated with atrazine, or tank mixed
with atrarihe,for use on medium and fine soils in
all of the above areas except CO.
May be tank mixed with propazine in eastern CO,
and central and western KS.
If weeds are present at the time of treatment,
metolachlor alone, formulated with or tank mixed
with atrazine may be tank mixed with glyphosate;
or paraquat.

                          Auxiliary Documentation

#100-645 (Bicep 6L) has a 2.64-3.55 Ib a.i.'/A dosage range for sorghum
(from table 5), which is much higher than the "normal" rate of 1.5-2 Ib
a.i./A.  I did not extend the entry's dosages to reflect this rate.

#100-597 (dual 8E) in the paragraph dealing with soybean tank mix/sequen-
tial application with metribuzin, they refer to a table 5 for dosages.  1
assumed table 7 to be the correct one and used it for the dosage calcula-
tion.

#100-638 (dual 25G) in the soybean, reduced-till, preplant surface appli-
cation, does not give a dosage rate.  The later mention of "2 Ib a.i./A"
on coarse soils not more than 2 weeks prior to planting" coincides with
the dual 8E label; it's the medium and fine texture soil dosages that were
lacking.  I assumed 2-3 Ib a.i./A to be the complete coarse to fine dosage
range as was on the dual 8E label.  Table 3 is not likely to be intended
for this use because the coarse soil rate of 2 Ib a.i./A is higher than
the lowest rate in table 3; this coincides with other no-till vs. conven-
tional till rates elsewhere in the labeling.

#100-597 (dual 8E) in final soybean use for no-till with metribuzin or
linuron and paraquat O£ glyphosate, does not specify application timing.
I assumed both preplant and preemergence.

                         APPENDIX IV

              GUIDE TO USE OP THIS BIBLIOGRAPHY
1.  CONTENT OP BIBLIOGRAPHY.  This bibliography contains
    citations of all studies considered relevant by EPA in
    arriving at the positions and conclusions stated elsewhere
    in the Standard.  Primary sources for studies in this
    bibliography have been the body of data submitted to EPA
    and its predecessor agencies in support of past regulatory
    decisions.  Selections from other sources including the
    published literature, in those instances where they have
    been considered, will be included.

2.  UNITS OP ENTRY.  The unit of entry in this bibliography
    is called a "study."  In the case of published materials,
    this corresponds closely to an article.  In the case of
    unpublished materials submitted to the Agency, the Agency
    has sought to Identify documents at a level parallel to
    the published article from within the typically larger
    volumes In which they were submitted.  The resulting
    "studies" generally have a distinct title (or at least a
   .single subject), can stand alone for purposes of review,
    and c:an be described with a conventional bibliographic
    citation.  The Agency has attempted also.to unite basic
    documents and commentaries upon them, treating them as a
    single study.

3.  IDENTIFICATION OP ENTRIES.  The entries in this bibliography
    are sorted numerically by "Master Record Identifier," or
    MRID, number.  This number is unique to the citation, and
    should be used at any time specific reference is required.
    It is not related to the six-digit "Accession Number"
    which has been used to identify volumes of submitted
    studies; see paragraph 4(d)(4) below.for a further explana-
    tion.  In a few cases, entries added to the bibliography
    late in the review may be preceded by a nine-character
    temporary identifier.  These entries are listed after
    all MRID entries.  This temporary identifier number Is
    also to be used whenever specific reference is needed.

H.  FORM OP ENTRY.  In addition to the Master Record Identifier
    (MRID), each entry consists of a citation containing
    standard elements followed, in the case of material
    submitted to EPA, by a description of the earliest known
    submission.  Bibliographic conventions used reflect the
    standards of the American National Standards Institute
    (ANSI), expanded to provide for certain special needs.
                                 119

-------
a.  Author.  Whenever the Agency could confidently identify
    one, the Agency has chosen to show a personal author.
    When no individual was Identified, the Agency has
    shown an Identifiable laboratory or testing facility
    as author.  As a last resort, the Agency has shown
    the first submitter as author.

b.  Document Date.  When the date appears as four digits
    with no question marks, the Agency took it directly
    from the document.  When a four-digit date is followed
    by a question mark, the bibliographer deduced the
    date from evidence in the document.  When the date
    appears as (19??), the Agency was unable to determine
    or estimate the date of the document.

c.  Title.   In some cases, it has been necessary for
    Agency  bibliographers to create or enhance a document
    title.   Any such editorial insertions are contained
    between square brackets.

d.  Trailing Parentheses.  For studies submitted to the
    Agency  in the past, the trailing parentheses include
    (in addition to any self-explanatory text) the fol-
    lowing  elements describing the earliest known submission:

    (1)  Submission Date.  The date of the earliest known
         submission appears immediately following the word
         "received."

    (2)  Administrative Number.  The next element,
         immediately following the word "under," is the
         registration number, experimental use permit
         number, petition number, or other administrative
         number associated with the earliest known submission.

    (3)  Submitter.  The third element is the submitter,
         following the phrase "submitted by."  When
         authorship is defaulted to the submitter, this
         element is omitted.

    (4)  Volume Identification (Accession Numbers).  The
         final element in the trailing parentheses
         identifies the EPA accession number of the volume
         in which the original submission of the study
         appears.  The six-digit accession number follows
         the symbol "CDL," standing for "Company Data
         Library."  This accession number is in turn
         followed by an alphabetic suffix which shows the
         relative position of the study within the volume.
         For example, within accession number 123456, the
         first study would be 123456-A; the second, 123456-
         B; the 26th, 123456-Z; and the 27th, 123456-AA.
