                       I.   INTRODUCTION

     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 FIFRA.  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.

     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
determine whether the pesticide meets the "no unreasonable
adverse effects" criteria of FIFRA.  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,1 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.
      The scientific reviews and Compendium of Acceptable „
Tses may be obtained from the OPP Public Docket.   Write to

-------
     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 FIFRA.  These steps may include:

     1.  Submittal 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 40 CFR Part 154 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 FIFRA 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, B, and C 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.  Registrants must notify

-------
the Agency of any information, including interim or preliminary
results of studies, if that information suggests possible
adverse effects on man or the environment.  This requirement is
independent of the specific time requirements imposed by EPA for
submittal of completed studies called in by the Agency and
continues as long as the products are registered under FIFRA.

     In 1987, the Agency issued a Data Call-In for manufacturing
process information to determine if MCPP pesticides become
contaminated with chlorinated dibenzo-p-dioxins or dibenzofurans
during manufacture.  The Agency is concerned that chemicals which
contain a halogenated cyclic moiety, such as MCPP, have the
potentiat-of becoming contaminated with chlorinated dibenzo-p-
dioxins or dibenzofurans under certain conditions of manufacture.
Submissions responding to this data call-in were received in
early 1988, too  late for inclusion in this standard.

-------
                          C.  Use Profile

     MCPP products are selective, systemic, post-emergent,
broadleaf herbicides that are used primarily on lawns and turf
found on golf courses, parks, around homes and institutions, and
along roads and fences.  They are also used on commercial sod.
The approximate percentages of MCPP pesticides used on an annual
basis by major use sites are 40 to 64% on golf courses, 32 to 53%
on home lawns, 4% on commercial sod, and 1 to 4% for other
outdoor applications.  Between 1 to 6 million pounds of active
ingredients are used annually.  Abut 10% of commercial sod is
treated with one or more of the MCPP pesticide products; and,
this treatment is usually in combination with other herbicides
and fertilizers.  MCPP is most often combined with the herbicides
2,4-D, dicamba, MSMA, MCPA, and/or DCPA in premixes or tank mixed
form.  Other MCPP use information is summarized below.

                     III.  AGENCY ASSESSMENT

     The Agency has reviewed all data in Agency files as of
November 21, 1987, supporting the registration of MCPP
pesticides.  The Agency's scientific findings and conclusions
are discussed in this section.

                        A.  Health  Effects

     Toxicity studies have been submitted on MCPP acid but not
on the salts or the isooctyl ester.  The studies on MCPP acid are
discussed below.  The toxicity data set for MCPP acid is complete
except for a dermal sensitization study, a 21-day dermal
toxicity study and a Chinese Hamster bone marrow cytogenetics
study, which are required.  Chronic toxicity, oncogenicity,
reproduction and general metabolism studies are not required
because MCPP and its salts and ester do not have food uses.

     The potassium salt is regarded as equivalent to MCPP acid,
so a separate toxicity data set is not required.  The
diethanolamine salt, dimethylamine salt and the isooctyl ester
are more complex moieties and may display different toxicological
properties.  Therefore a full set of acute studies, including
inhalation, subchronic  (21-day) dermal toxicity, teratogenicity
and mutagenicity studies are required for each of these
materials.
     1. Acute Toxicity

     Technical MCPP acid can be lethal following acute oral
exposure, but the toxicity is low.  Acute oral exposure of rats
to 500 mg/kg or greater caused labored breathing, prostration,
and death (1*050 - 558 mg/kg of technical MCPP—Toxicity Category
III).

     The dermal toxicity is low.  Application of 2 g/kg to skin
of rabbits caused no deaths, placing MCPP acid in Toxicity
Category IV via this route.

     Available data are inadequate to characterize the acute
inhalation toxicity of MCPP.

     2. Primary Eye Irritation

     Sufficient data are available to indicate that technical
MCPP acid produces persistent corneal opacities, iritis, and
conjunctival irritation in both washed and unwashed eyes.
MCPP acid causes significant and persistent eye irritation,
which places it in Toxicity Category I.

-------
     3.  Primary Dermal Irritation

     Sufficient data are available to indicate that technical
MCPP acid causes no dermal irritation in rabbits exposed for 24
hours to O.Sg on both abraded and unabraded skin.

     4.  Acute Delayed Neurotoxieitv

     No data are available on the acute delayed neurotoxicity of
MCPP. Since this test is only required for organophosphate
inhibitors of cholinesterase or analogs or metabolites of such
inhibitors, and MCPP does not fall in one of these categories, a
study is not required.

     5.  $uj?ch.ronic Oral

     An acceptable study in rats is available on the subchronic
oral toxicity of technical MCPP acid.  Oral exposure of 15
rats/sex to technical MCPP for 90 days at doses of 3, 9, and 27
mg/kg caused increased creatinine levels in females and decreased
glucose levels in males at 27 mg/kg; increased kidney weights in
both sexes at 27 mg/kg and males at 9mg/kg; and increased
relative kidney weights in both sexes at 9 and 27 mg/kg. The NOEL
was 3 .mg/kg.

     6.  S\lb.ch.ronic Dermal

     Data are not available on the subchronic dermal toxicity of
MCPP.

     7. Teratoaenieity

     A teratogenicity study in rats with MCPP acid showed no
maternal effects, but, at 125 mg/kg, increased intra-uterine
deaths, decreased crown/rump lengths, and an increased incidence
of delayed or absent ossification of the sternebrae were
reported.  Twenty eight female rats/dose were given doses of 20,
50, or 125 mg/kg of MCPP on days 6-15 of gestation.  There were
38 control females.  The "No Observable Effect Level" (NOEL) was
50 mg/kg.

     A teratogenicity study in rabbits showed no fetotoxic or
teratogenic effects, and only slight body weight gain
differences in the mothers exposed to 75 mg/kg.  Fifteen
rabbits/dose were given 12, 30, or 75 mg/kg/day of MCPP acid on
days 6-18 of gestation. There were 30 control rabbits.  There
were no effects of exposure on fetotoxicity or teratogenicity
measures.  The maternal NOEL was 30 mg/kg.  The developmental
NOEL was greater than 75 mg/kg.

     8.  Mutaoenicitv.

        a.  Gene Mutations.  Sufficient data are available to
demonstrate the potential of MCPP acid to cause gene mutations.
In an acceptable study, no increases were seen in either: (1)
Reverse mutation in four Salmonella strains exposed to paper
discs impregnated with 2000 ug MCPP (spot test), in both the
presence and absence of liver microsomes from rats treated with
phenobarbital; or (2) Forward mutation to streptomycin resistance
in S. coelicolor A3(2) exposed to increasing concentrations of
MCPP up to 1000 ug, in both spot and standard plate incorporation
tests, also with and without metabolic activation of rat liver
microsomes with phenobarbitol.

        b. Chromosomal flbeiT?tJ91?-  Available data are inadequate
to characterize the effects of MCPP on chromosomal aberrations.
A Chinese Hamster bone marrow cytogenetics study is required.

        c. Other Tests.  Sufficient data are available to
characterize the effects of MCPP acid on sister chromatid
exchange (SCE).  MCPP caused an increase in SCE after single oral
doses of 470 and 3800 mg/kg in Chinese Hamsters.  MCPP was
positive for increasing SCEs in a dose-dependent fashion above
the control value of 3.06 SCEs/cell, at single oral doses of 470
mg/kg  (3.77 SCEs/cell, p < 0.05) and 3800'mg/kg (5.21 SCEs/cell,
p < 0.01), both doses also causing clinical toxicity.

     10.   Special Studies

     As discussed below in Section II. B. 2, Applicator
Exposure f additional data are needed to assess the risk posed by
the teratogenic potential of MCPP.  A dermal absorption study is
needed to refine exposure assessments.  If the dermal absortion
study shows there is significant absorption of MCPP, a dermal
teratogenicity study will be required.
                                11

                       B.  Human Exposure

     1 .  Poisoning Incidents

     There are no reports of poisoning incidents for MCPP.

     2.  Applicator Exposure

         a.  Preliminary Risk Assessment

     One biological monitoring study reported on results of
urinary MCPP excretion in commercial lawn applicators.  The
study measured exposure to applicators applying a mixture of
MCPP, 2,4-D, and Dicamba to lawns with hand-held large droplet
nozzle sprayers.  The concentration of MCPP used in that study
was 330 mg/1.  There was no MCPP detected in applicators' urine
samples greater than 0.01 ppm, the lowest level detectable with
the analytical method used.

     The Agency used surrogate data to evaluate expected exposure
associated with the handling of MCPP.  Exposure and risk
estimates were made based on the three typical uses of MCPP for
mixers, loaders, and applicators using open pour and closed
loading for 1) commercial lawn, 2)  commercial sod use with
compressed air and hose end sprayers, and for 3) home-owner use.
The results are discussed below and summarized in the table which
follows.
     Exposure ^o ?n individual mixing . loading and applying
     MCPF on a commercial sod farm was estimated to be 1.0
     mg/kg/day.  This estimation assumed that the
     mixer/loader wore gloves and a long sleeved shirt and
     long pants during the open pour loading, and then
     applied the MCPP using ground boom equipment (without
     wearing gloves).  Based on the NOEL of 50 mg/kg/day for
     developmental effects, and a dermal absorption of 100%,
     the calculated MOS for the commercial sod farmer is
     estimated to be 50.

     The exposure for the commercial home lawn mixer /loaders
     uffifltg an open pour system is estimated to be about 0.43
     mg/kg/day, assuming gloves, a long sleeved shirt, and
     long pants are worn.  This is equivalent to a MOS about
     120 for the mixing and loading operation, based on a
     NOEL of 50 mg/kg/day, a dermal absorption of 100%, and
     surrogate data from the 1987 Dinoseb testimony of Curt
     Lunchick.  The applicator was assumed to be a different
     individual than the mixer/loader.

     The MOS for the homeowner was calculated assuming short
     sleeved shirts, long pants and shoes were worn during
     all handling operations, including application using

                                12

-------
     compressed air sprayers or hose end sprayers.  The
     typical application was assumed to involve the use of
     0.36 Ib active equivalent HCPP/acre for 3.7 hours a
     day.  Surrogate data published by J.E. Davis, et al.
     were used to roughly estimate the exposure to
     homeowners.

     Based on the 50 mg/kg/day NOEL and a dermal absorption
     of 100%, the exposure to homeowners would be about
     0.024 mg/kg/day (MOS«2100) if compressed air sprayers
     were used, and be about 0.082 mg/kg/day (MOS-610) if
     hose end sprayers were used.  (Exposure estimates may
     be underestimated because homeowners typically wear
     only minimal clothing during pesticide treatment.)
     The Davis study was considered too limited for a final
     exposure assessment for the reregistration of HCPP.

     The Agency believes these estimates overstate the actual
risk.  Most liquid formulations have dermal absorption of 50% or
less (usually 5-25%) and not 100%.  The Agency finds that the MOS
for commercial sod farmers and workers exposed through other uses
would probably be over 100 when corrected for the actual extent
of dermal absorption.

     b.  Exposure DataRequirements

     Applicator Exposure Data

     Because of the inadequacy of the available exposure data,
the Agency is requiring exposure studies for the following uses:
commercial hone lawns (hose end sprayer, power sprayer, back
pack)y commercial turf (ground boom); and homeowner use (hose end
sprayer and compressed air sprayer).   Exposure studies for any
other uses of MCPP should also be included.  Protocols for these
studies should be submitted for Agency approval prior to
initiation of the studies.

     Reentry Data

     MCPP meets both the toxicity and exposure criteria for
requiring reentry data.  MCPP has been determined to be a
developmental toxicant and workers may receive post-application
exposure to MCPP through its commercial use on turf.  Thus ,the
Agency is requiring foliar dissipation, soil dissipation, and
dermal exposure studies.  These data are needed to assess
exposure to MCPP residues resulting from reentry into treated
areas on commercial turf farms to harvest or handle treated
turf.  Respiratory exposure data requirements are reserved,
pending submission and Agency evaluation of the complete
toxicology data base for MCPP, including dermal and inhalation
toxicity.                                   '

     These data will also be used to assess the risks to persons
exposed to residues on lawns, golf courses and other areas where
MCPP is applied.

                  C.   Environmental Fate Profile

     Environmental fate studies partially satisfy the data
requirements for the MCPP acid and its inorganic potassium salt.
Studies were presented on the MCPP acid only.  There are no
acceptable studies for the organic salt and ester forms of MCPP.
The available data are insufficient to fully assess the
environmental fate of these MCPP pesticides.  Data for
terrestrial nonfood and aquatic nonfood uses must be submitted
for all each MCPP pesticide  (see table A).

     1.  Hydrolysis

     Supplemental hydrolysis data  indicate that MCPP acid was
stable to hydrolysis: Ring-labeled [14C]MCPP (96.9% pure) at
51-52 ppm did not hydrolyze during 740-751 hours of incubation in
sterile buffered aqueous solutions (pH 5, 7, and 9) at 25 C.
                                14

-------
     2.  Photodegrration in Water

     There was slow photodegradation in water for the sane ring
labeled [14C]MCPP formulation, with a half-life of 739 hours at
the same pHs under continuous irradiation with artificial light.
Two major and several minor degradates were isolated.  There was
no degradation of the MCPP acid formulation in the dark control
solutions during 739-748 hours of incubation.

     3.  Leaching and Adsorption/Desorption of Aged MCPP
          Residues

     Based on batch equilibrium experiments, ring-labeled
[14C]MCPP acid  (>96% purity) at 0.606-12.0 ug/mL, was very
mobile in sand, sandy loam, silt loam, and silty clay loam soils;
Freundlich Kads values ranged from 0.199 to 0.687.  The
equilibrations were conducted in 3 g/10 mL soil:solution
for 1 hour.  Adsorption was strongly correlated with the organic
matter content of the soils (correlation coefficients ranged
from 0.950-0.999).  In general, 25-51% of MCPP was desorbed from
the soils after 1 hour of shaking with MCPP-free solutions.

     Based on soil TLC experiments, ring-labeled [14C]MCPP acid
(>96.3% purity) was very mobile in sand, sandy loam, and silt
loam soils (Rf 0.93-1.0), and was mobile in silty clay loam soil
(Rf 0.74).

     Based on soil TLC experiments, unaged ring-labeled[14C]MCPP
acid (>96.3% purity) was mobile (Rf 0.86) in sandy loam soil.
However, supplemental information indicated that uncharacterized
aged (30 days) [14C]MCPP residues were immobile in sandy loam
soil (Rf 0.08).

     4.  Ground Water Assessment

     Available data indicate that MCPP acid is mobile in many
mineral soils, and if not first degraded, may potentially leach
to groundwater.  However, it is unclear whether it is possible
for there to be sufficient persistence in the root zone to allow
measurable leaching to ground water.  No ground water monitoring
studies are required at this time, but if the requested
environmental fate studies indicate that MCPP or its degradates
remain in water and may leach significantly, a monitoring study
may be required.
                                15

-------
     5*  Pesticide ACTmnM^ation in Fist}

     There is low level bioaccumulation of MCPP acid in fish.
[14C] NCPP residues accumulated in bluegill sunfish with
bioconcentration factors of 1.2, 5.5, and 3.OX in edible tissues,
nonedible tissues, (head, gills, viscera, and fins), and whole
fish, respectively, during 28 days of exposure at 1 ppo in a
flow-through system.  Maximum levels of [14C] residues were 1.35
ppm in edible tissues, 5.62 ppm in non-edible tissues, and 3.09
ppm in whole fish.  In the edible tissues, MCPP residues were
found to be 0.23-0.24 ppm at 21 and 28 days post treatment.  The
major degradate in the edible tissues was "mecoprop methyl",
which was isolated at 0.34 ppm and 0.47 ppm at 21 and 28 days,
respectively.  At 21 and 28 days posttreatment, two unidentified
degradates were 0.05-0.19 ppm; uncharacterized residues in the
water soluble phase of the extracts were 0.09-15.4 ppm; and
unextractables were 0.24-0.26 ppm.  Residues accumulated at 28
days were depurated quickly; at day 14 of depuration, [14C]
residues were 0.03 ppm in edible tissues, 0.64 ppm in nonedible
tissues, and 0.29 ppm in whole fish.  The Agency finds that the
observed levels of bioaccumullation are of virtually no
significance.

                      D.   Ecological Effects

     1.  End Use Products

     The only studies received which tested MCPP end use
products were those in which the test substance a mixture of one
or more forms of MCPP and other active ingredients.  Because data
on mixtures are not acceptable, these studies were not reviewed.
End use product testing  is incomplete as discussed below and data
are required.

     2.  Technical Products

     a.  Avian Studies

     Avian toxicity data are complete for MCPP acid, partially
complete for MCPP dimethylamine salt, and nonexistent for all
other MCPP pesticides.   However, the Agency will accept data on
MCPP acid to support uses of the potassium salt of MCPP.   (See
data requirements  in the Data Table A in Appendix I.)

     1) Avian sincrle-doae oral  studies on MCPP acid  indicate
     an acute oral LD50  value of 700 mg/kg  for the bobwhite
     quail.  MCPP  acid may therefore be considered slightly
     toxic to avian species on  an acute basis.  Based on
     available toxicity  information, no .precautionary
     labeling for  MCPP acid nor MCPP potassium salt  is
     indicated.  No acute oral  studies were submitted for

                                16

-------
the salts or ester MCPP products; therefore, no acute
toxicity determinations can be made at this time for
the diethanolamine salt, dimethyl salt, and the
isooctyl ester forms of MCPP.
2) Avian dietary studies on MCPP acid indicate
values of >5620 ppm for the mallard and 5000 ppm for
the bobwhite.  MCPP acid may therefore be considered
practically non-toxic to avian species on a subacute
basis.  Dietary studies for MCPP dimethylamine salt
indicate LCsg values greater than 12000 ppm for the
mallard and 14000 ppm for the Japanese quail.
However, the Japanese quail is not considered
representative of an upland game bird in the United
States.  The bobwhite quail is the preferred species.
Thus, the Japanese quail study does not fulfill EPA
requirements .

Additional avian dietary data are required on the MCPP
dimethylamine salt; and, all data are required for the
diethanolamine salt and the isooctyl ester.  Although
Guidelines requirements are only partially fulfilled,
the above data indicate that MCPP dimethylamine salt
has very low toxicity to avian species on a subacute
dietary basis.  No determination of dietary toxicity to
avian species can be made for the diethanolamine salt
or the isooctyl ester because of a lack of acceptable
studies.                             .

3) Avian Reproduction Testing.  No avian reproduction
studies were submitted.  There is insufficient toxicity
and environmental fate data available at this time to
determine if this test is required for any of the forms
of MCPP.

b.  Aquatic Studies

1) Acute Freshwater Fish Toxicity Testing.

Available freshwater fish toxicity studies indicate
that MCPP acid (technical formulation) has very low
acute toxicity to freshwater fish (rainbow trout LC50 -
124 ppm) .  The submission of rainbow trout (a coldwater
species) studies only partially satisfied the
freshwater fish data requirements for the MCPP acid and
MCPP potassium salt.  The data requirement for testing
a warmwater species has not been fulfilled.

A determination of acute toxicity for technical or end-
use products to freshwater fish cannot be made for the
dimethylamine salt, the diethanolamine salt, or the
isooctyl ester because of a lack of toxicity data.

                           17

-------
     2) Acute Freshwater Aquatic Invertebrate Testing.
     There were no acceptable acute freshwater aquatic
     invertebrate data received.  Therefore, the requirement
     for acute toxicity testing for technical and end use
     products containing MCPP on freshwater aquatic
     invertebrates has not been fulfilled.

     3) Effects on Eatuarine and Marine Organisms.  Given
     that MCPP formulations are used in drainage ditch-banks
     and that MCPP is a major herbicide used on turf (with
     golf courses in the mid-Atlantic region accounting for
     most of this use), significant runoff to estuarine/
     marine environments may be expected.  There were no
     studies on estuarine and marine organisms submitted for
     review.  Therefore, the requirement for acute toxicity
     testing for the acid and all salt and ester forms of
     MCPP on estuarine and marine organisms has not been
     fulfilled.  Testing is required for some formulations
     and reserved for others, pending the results of acute
     aquatic freshwater fish and acute aquatic freshwater
     invertebrate studies and environmental fate data.

     4)  Fish Early Life-Stage and Aquatic Invertebrate
     Life-Cvcle Testing.  There were no fish early life-
     stage nor aquatic invertebrate life-cycle test results
     submitted using either technical or typical end use
     MCPP products.  There is insufficient acute toxicity
     data and environmental fate data available at this time
     to determine if these tests are required.  Thus,
     requirements for testing technical and end use acid,
     salt, and ester formulations of MCPP are reserved for
     fish early life-stage and aquatic invertebrate
     organisms.

     c.  Nontarqret Plants

     There are no acceptable data for toxicity of any MCPP
formulation to nontarget plants.  Therefore, no assessment of
toxicity can be made at this time.

     Air- MCPP formulations are labeled to control a variety of
broadleaf weeds.  Therefore, Tier I testing will not be required
because, by definition, herbicides are hazardous to plants.  In
order to assess the potential hazard to nontarget plants, the
Tier II nontarget plant studies as specified in the data table
in Appendix I  are required for all forms of MCPP.  Further, for
those MCPP formulations for which drainage ditchbank application
is identified (dimethylamine salt, potassium salt, isooctyl
ester), Tier II aquatic plant testing must utilize all of the
following species: 1) duck-weed fLemna gibbal, 2) marine diatoms
fSkeletonema costaturn). 3) blue-green alga  (Anabaena flos-aquael.

                                18

-------
4) freshwater green alga (Selenastrum capricornutum), and 5) a
freshwater diatom. For those MCPP formulations not identified as
having drainage ditchbank application (MCPP acid and
diethanolamine salt), testing may be completed using Selenastrum
capricornutum.

     d. Endana e r ed Spec i e s

     There are no data to indicate whether MCPP acid or any MCPP
salt or ester formulation may affect endangered plant or animal
species.  Therefore, the Agency cannot assess the potential of
MCPP or its salts or ester to adversely affect endangered
species.

     e. Nontarget Insects

     There are no data to indicate whether products containing
MCPP acid or its salts and ester affect honeybees and nontarget
insects.  No determination can be made that MCPP acid or any salt
or ester form of MCPP will adversely affect nontarget insects.
No data are required at this time.

                    E.  Other  Science  Findings

     MCPP acid and its salts and ester contain a chlorinated
phenoxy group within their structure.   The Agency has found that
chemicals having such components in their structure may have been
produced under conditions which can lead to-the formation of
chlorinated dibenzo-p-dioxins or dibenzofurans as manufacturing
impurities.  Accordingly, the Agency has required the submission
of manufacturing process information to address this possibility.
The Agency will evaluate these data to assess the likelihood of
dioxin/furan formation during manufacture.  If the manufacturing
process data show that chlorinated dibenzo-p-dioxins or
dibenzofurans are likely to occur, the Agency may require
analytical data to characterize or quantify these contaminants.
The Agency's concern about chlorinated dibenzo-p-dioxins and
dibenzofurans is based on the extreme toxicity of 2,3,7,8-
tetrachloro-dibenzo-p-dioxin, which causes lethal effects in
aquatic species, birds and some mammals.  These impurities are
also known to be carcinogenic, teratogenic, fetotoxic, and
acnegenic.

     The Agency is also concerned that the amine salts of MCPP
may become contaminated by nitrosamines under certain conditions
of manufacture and storage.  Information on the manufacture and
storage of products containing MCPP amine salts is required to
assess possible contamination.  The Agency's concern is based on
the well-established carcinogenicity of nitrosamines.
                                19

-------
             IV.  REGULATORY POSITION AND

             A.  REGULATORY POSITIONS AND
     The Agency has made the following determinations based on
review and evaluation of all available acceptable data on MCPP
pesticides .

1.  Special Review

     The Agency is deferring a decision on initiating a Special
Review of MCPP pesticides until data needed to refine worker
exposure estimates have been submitted and evaluated.

Rationale;  A teratogenicty study in rats showed a NOEL of 50
mg/kg for developmental effects of MCPP acid.  The Agency
estimated exposures to workers and users of MCPP pesticide
products and found that margins of safety were below 100 for
mixer/ loaders and applicators handling MCPP in commercial sod
farms.  These estimates are based upon the assumption that the
rate of dermal absorption is 100 percent.  The Agency is
requiring dermal absorption and applicator exposure data so that
these risk estimates can be refined.  When these data are
available, the Agency will evaluate them to determine whether
further regulatory action is warranted.

     Based on dermal absorption data' obtained on other
pesticides, the Agency believes that the rate of dermal
absorption is likely to be below 50 percent.  Therefore, the
Agency believes that risks to workers are likely to be acceptable
for dermal absorption.  Accordingly, other than requiring the use
of protective clothing (which would be required in any case) , the
Agency is not imposing any interim risk reduction measures.


2.  Restricted Use

     The Agency will not restrict the use of MCPP products at
this time.

Rationale;  The Agency does not have sufficient information to
determine that classification of MCPP pesticides as restricted
use pesticides is warranted.  The Agency is requiring data needed
to refine worker exposure estimates.  When these data become
available, the Agency will assess the risks posed by use of MCPP
pesticides and will reexamine its position on classification.
                                20

-------
3.  Exposure Data Requirements

     The Agency is requiring a dermal penetration study and
exposure estimates for applicators involved in commercial lawn
uses.  A dermal teratology study may also be required if the
dermal absorption of MCPP is significant.  These data are needed
to assess the teratogenic risk posed by MCPP pesticides to
persons handling MCPP pesticides for lawns, turf, and sod
applications.

Rationale;  A preliminary risk assessment of the developmental
effects of MCPP, based upon limited exposure data and the
assumption of 100% dermal absorption, showed inadequate margins
of safety for some categories of workers.  The required studies
will provide data needed to refine the exposure estimates for
these workers and more accurately assess the margins of safety.

4.  Basic Data Requirements

     The Agency will require data specific to the amines and the
ester formulations as well as the acid, as reflected in the data
tables.

Rationale:  When MCPP is formulated as an ester or amine, the
physical characteristics, biological activity and fate in the
environment may be affected.  The Agency has little or no data to
evaluate the effects of the ester or amine derivatives of. MCPP.
Data on each amine and ester derivative are needed.to evaluate
the hazards associated with each registered form of MCPP.

5.  Ground Water Concerns

     The Agency will evaluate the potential of MCPP pesticides to
contaminate ground water after receiving and evaluating
additional required environmental fate studies.  Until these
studies are submitted and evaluated, the statement given in
section IV. D is required.

Rationale;  MCPP pesticides have been identified as chemicals
with the potential to contaminate ground water because they are
mobile in mineral soils.  It is unknown whether MCPP will
persist^sufficiently in the soil surface to prevent measurable
leaching into ground water.

6.  Reentry Data Requirement

     The Agency will require reentry data for MCPP pesticides.
Workers are not to reenter treated areas until the spray has
dried or the dust has settled. (See label statements given in
Section IV. D.)
                                21

-------
            Reentry data requirements are triggered by the
finding that MCPP is teratogenic in the rat and that its uses,
such as the commercial sod farm use, require workers to reenter
MCPP-treated areas.  It is therefore necessary to obtain data
needed to estimate the extent of worker exposure to MCPP
residues. In order to minimize exposure to MCPP residues , workers
should not reenter treated areas unitl the spray has dried or the
dust has settled.

7.  Protective Clothing Requirement

     The Agency is requiring that protective clothing be used.
Mixer/loaders and applicators must wear long pants, long sleeved
shirts, and gloves.  Persons applying liquid MCPP products such
as sprays, are required to use goggles to cover their eyes.   (See
label statements given in Section IV. D.)


Rationale;  These measures are needed to reduce dermal and ocular
exposure to MCPP.  Eye exposure should be reduced because MCPP is
extremely irritating to the eye (it has been placed in toxicity
category I for primary eye irritation) .  Exposure via the dermal
route, which is the major route of exposure, should be reduced
because of the teratogenic potential of MCPP.

8.  Endangered Species

     Until all required toxicity .studies are received and
evaluated, there can be no determination that MCPP acid or any
MCPP pesticide' would affect endangered animal or plant species.
Therefore, no endangered species labeling statement is required
at this time.

Rationale;  The Agency lacks data to show whether the use of  MCPP
pesticides affect any endangered plant or animal species.
Phytotoxicity data on nontarget plants are required.  If data
indicate that endangered species may be adversely affected by
registered uses of MCPP, the Agency will initiate consultation to
determine what measures are necessary to preclude jeopardy to
those species.

9.  Dio^ins /Dibenzofurans

     The Agency  is requiring the submission of manufacturing  and
product chemistry data to address the potential contamination of
MCPP and  its salts, amines and esters with chlorinated dibenzo-p-
dioxins and dibenzofurans.

Rationale;  Chemicals with chlorinated cyclic components may
become contaminated with chlorinated dibenzo-p-dioxins and
dibenzofurans  under certain conditions of manufacture.
Information on the manufacture of MCPP acid  and  its salts  and

                                22

-------
esters is required to assess whether contamination with such
impurities is likely to occur.  The Agency's concern  is based
upon the toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin and the
potential toxicity of related compounds.

10.  Nitrosamines

     The Agency is requiring the submission of analytical and
product chemistry data to address the possible contamination of
MCPP amines with nitrosamines.

Rationale!  Nitrosamines might be produced in MCPP amine salts
under certain conditions of manufacture and storage.  Information
on the manufacture and storage of MCPP amine salts is required to
assess possible contamination.  The Agency's concern is based on
the well-established carcinogenicity of nitrosamines.

11.  Data for Immediate Agency Review

     The Agency has identified certain data that will receive
immediate review when submitted.

Rationale:  Certain of the data being required are essential to
resolve risk concerns, or may trigger the need for further
studies which should be initiated as soon as possible.  The
following studies have been identified to receive priority
review as soon as they are received by the Agency:  product
chemistry, environmental fate, dermal absorption, applicator
exposure'and reentry data, toxicity data on MCPP salts and ester,
and Tier II phytotoxicity data.

12.  Cqntinuation of Registration.

     While data gaps are being filled, currently registered
manufacturing use products (MPs) and end use products (EPs)
containing MCPP may be sold, distributed, formulated and used,
subject to the terms and conditions specified in this Standard.
Registrants must provide or agree to develop additional data,
as specified in the Data Appendices, in order to maintain
existing registrations.

Rationale-:  Under FIFRA, the Agency does not normally cancel or
withhold registration simply because data are missing or are
inadequate (see FIFRA section 3(c)(2)(B) and 3(c)(7)).
Issuance of this Standard provides a mechanism for identifying
data needs and labeling changes arising from available data.
Required data will be reviewed and evaluated, after which the
Agency will determine if additional regulatory actions are
necessary.

                  B.  CRITERIA FOR REGISTRATION

     To be registered or reregistered under this standard,
products must contain one or more of the forms of MCPP
(Mecoprop) , bear required labeling, and conform to the product
composition, acute toxicity limits, and use pattern requirements
listed in this document.
                 C.  ACCEPTABLE FAFGES AND  LIMITS

1.  Product Composition Standard

     To be registered or reregistered under this Standard,
manufacturing-use products (MPs)  must contain one or more of the
following MCPP products: MCPP acid; MCPP potassium salt; MCPP
diethanolamine salt; MCPP dimethylamine salt; MCPP isooctyl
ester.  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%.

2.  Acute Toxicity Limits

     The Agency will consider registration of technical grade
and manufacturing-use products containing any of the above forms
of MCPP pesticides 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 products
bearing Federally registered uses.  The EPA Compendium of
Acceptable Uses lists all registered uses, as well as approved
maximum application rates and frequencies  (for availability, see
page 1) .

     The use patterns currently registered are nonfood
terrestrial, aquatic, forestry, and domestic.

                           0.   LABELING

     All products must bear appropriate labeling as specified in
40 CFR 156.10, PR Notices 83-2, 83-3 and this Standard, or must
be revised to conform to those specifications.  Appendix II
contains information on label requirements.

     Time Frames for Compliance.   Pesticide products containing
one or more of the forms of MCPP may not be released for shipment
by the registrant after December 1989, unless the products bear

                                24

-------
amended labels which comply with the requirements of this
Standard.

     Likewise, pesticide products containing one or more of these
forms of HCPP may not be distributed or sold after December 1990,
unless the products bear amended labels which comply with the
requirements of this Standard.

     The following specific information must appear on the
labeling of all manufacturing and end use MCPP products:

     1.  Ingredients Statement

     The ingredient statement for products must list the
     active ingredient as:

     ACTIVE INGREDIENT
     2-(2-methyl-4-chlorophenoxy) propionic acid  	%
                               OR

     (Applicable salt or ester)  ................. _ %
     2-(2-methyl-4-chlorophenoxy)  propionic acid
     equivalent : ................................ _ %

     INERT INGREDIENT (S)
     2.  Use Pattern Statements

     Manufacturing-Use Products
     All manufacturing-use products must state that they are
     intended for formulation into end-use products for
     acceptable use patterns.

     End— Use Products
     Labeling must specify sites which are listed in the EPA
     Compendium of Acceptable Uses.  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
     pat Cum.

     3 .  Precautionary Statements

     Statements for Manufacturing-Use Products

     "Do not discharge effluent containing this product into
     lakes streams, ponds,  estuaries,  oceans,  or public
     waters, unless this product is specifically identified
     and addressed in an NPDES permit.   Do not discharge
     effluent containing this product to sewer systems
     without previously notifying the sewage treatment

plant authority.  For guidance, contact your State
Water Board or Regional Office of the EPA.
Statements for End-Use Products

Ground Water
"Although highly mobile, in general phenoxy herbicides
such as MCPP are not sufficiently persistent to reach
groundwater from use as specified on product labels.
Most cases of ground water contamination involving
phenoxy herbicides have been associated with
mixing/ loading and disposal sites.  Caution should be
exercised when handling MCPP pesticides at such sites
to prevent contamination of water supplies."

Protective Clothing;
"Mixers/ loaders and applicators must wear long pants,
long sleeved shirts and gloves. Persons applying
liquid MCPP products such as sprays are required to use
goggles to cover their eyes."  Mixers/ loaders may use
face shield or goggles during mixing/loading
operations, in addition to the protective clothing.

Worker Reentry;
"Do not reenter or permit workers to reenter treated
areas until sprays have dried or dusts have settled."

Nontaroet Plant Species;
Aquatic Uses
"Drift or run-off may adversely affect nontarget
plants.  Do not apply directly except as specified on
this label.  Do not contaminate water when disposing of
equipment washwaters."

Non-aquatic Uses;
"Drift or run-off may adversely affect nontarget
plants.  Do not apply directly to water or wetlands
(swamps, bog, marshes, and potholes).  Do not
contaminate washwaters . "
                           26

              V.  PRODUCTS SUBJECT TO THIS STANDARD

     All products containing one or more of the pesticides
identified in Section II.A. are subject to certain requirements
for data submittal 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
follow:

A.  Manufacturing use products containing this pesticide as the
sole active ingredient are subject to:

1.  The restrictions (if any) upon use, composition, or packaging
listed in Section IV, if they pertain to the manufacturing use
product.

2.  The data requirements listed in Tables A and B2

3.  The labeling requirements specified for manufacturing use
products in Section IV.

     4.  Administrative requirements  (application forms,
Confidential statement-of Formula, data compensation provisions)
associated with reregistration.

B.  Manufacturing use products containing this pesticide
as one of multiple active ingredients are subject to:

1.  The data requirements listed in Table A.

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 an end use producer who is eligible for the
generic data exemption for that active ingredient.

Table C lists product-specific data applicable to end use
products.  The Agency has decided that, in most cases, it will
not require the submittal of product-specific data for end use
products at this time.  Therefore most Registration Standards do
not contain a Table C.
2 Data requirements are listed in the three Tables in
Appendix I of this Registration Standard.  The Guide to
Tables in that Appendix explains how to read the Tables.

                                27

-------
     2.  The labeling requirements specified for manufacturing
use products in Section IV.

C.  End use products containing this pesticide as the
sole active ingredient are subject to:

1.  The restrictions (if any) upon use, composition, or packaging
listed in Section IV if they pertain to the end use product.

2.  If eligible for the generic data exemptions, the data
requirements listed in Table C.

3.  If not eligible for the generic data exemption, the data
requirements listed in Table A and the data requirements listed
in Table C.

4.  The labeling requirements specified for end use products in
Section IV.

D.  End use products containing this pesticide as one of multiple
active ingredients are subject to:

1.  If not eligible for the generic data exemption, the data
requirements listed in Tables A and C.

2.  If eligible for the generic data exemption, the data
requirements listed in Table C.

3.  The labeling requirements specified for end use products in
Section IV.

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 the data
requirements in Table A.
3 If you purchase from another producer and use as the
source of your active ingredient only EPA-registered products,
you are eligible for the generic data exemption for generic data
concerning that active ingredient (Table A) and product-
specific data for the registered manufacturing use product you
purchase (Table B).

                                28

-------
       vi.  ^FQUTREMENT 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 registration
of products containing this active ingredient.4

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 resppnse to a data request under FIFRA sec.
3(c)(2)(B) (DCI Notice).  EPA has decided, however, not to-
require a registrant who qualifies for the f emulator' s
exemption (FIFRA 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 granted a generic data exemption, you rely on
the efforts of other persons to provide the Agency with the
required data.  If the registrants who have committed to
generate and submit the required data fail to take appropriate
steps to meet the requirements or are no longer in compliance
with this data requirements notice, the Agency will consider
that both they and you are not in compliance and will normally
initiate-proceedings to suspend the registrations of both
your product(s) and their product(s) unless you commit to submit
and submit the required data in the specified timeframe.  In
such cases, the Agency generally will not grant a time extension
for submitting the data.
4 Registrations granted after issuance of this Standard will be
conditioned upon submittal or citation of the data listed in
this Registration Standard.
                                29

-------
     If you are not now eligible for a generic data 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 Generic Data Exemption
Statement.

     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 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 submittal 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 FIFRA 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 (FIFRA sec. 6(e)).

C.  What generic data must be s^bj^i^^ed.?

     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.

0.  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 "FIFRA 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.  XQU will fl^frffit the data yourself.

     2 .J--.Y.OU have entered into an agreement with one or more
registrants to lointlv develop  for 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


                                30

-------
exists, or (3) a written statement by the person who will be
submitting the data that you may rely upon its submittal.
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 terms of the final arrangement
between the parties or a mechanism to resolve the terms.

     If you and other registrants together are generating or
submitting requested data as a task force or consortium, a
representative of the group should request a Joint Data
Submitter Number, as part of your 90-day response.  The
request must include the following information:

     a.  A list of the members of the consortium;
     b.  The name and address of the designated representative
               of the consortium, with whom EPA will correspond
         concerning the data;
     c.  Identity of the Registration Standard containing
         the data requirement;
     d.  A list of the products affected (from all members
          of the consortium); and
     e.  Identification of the specific data that the consortium
will be generating or submitting.

     The Agency will assign a number to the consortium, which
should be used on all data submittals by the consortium.  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 Development
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, contain the following language or its equivalent:
                                31

-------
     [Your company name] offers to share in the burden of
     producing the data required pursuant to FIFRA sec.
     3(c)(2)(B)  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 as required by this
Notice in a timely manner.  If the other registrant fails to
develop the data or for some other reason would be subject to
suspension, your registration as well as that of the other
registrant will normally be subject to initiation of suspension
proceedings, unless you commit to submit and submit the required
data in the specified timeframe.  In such cases, the Agency
generally will not grant a time extension for submitting the
data.

     4.  You request_fr 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.  The Agency will respond in writing to your request
for a waiver.

     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 vour oroductfs)  for which the data are needed.
                                32

-------
E.  Registrant Requests Regarding Data Requirements and Agency
     Responses

     All requests for modification of data requirements'
(inapplicability, waiver), approval of protocols or protocol
changes, or time extensions must be submitted in writing.
The original requirement remains in effect unless the Agency has
notified you in writing that it has agreed to a change in the
requirement.  While being considered by the Agency, such
requests for changes in the requirements do not alter the
original requirements or extend the time allowed for meeting the
requirement.

F.  Test Protocols and Standards

    All studies required under this Notice must be conducted in
accordance with test standards outlined in the Pesticide
Assessment Guidelines, unless other protocol or standards are
approved for use by the Agency in writing.  All testing must be
conducted in accordance with applicable Good Laboratory
Practices regulations in 40 CFR Part 160.

    The Pesticide Assessment Guidelines, which are referenced in
the Data Tables, are available from the National Technical
Information Service (NTIS), Attn: Order Desk, 5285 Port Royal
Road, Springfield, VA  22161 (tel: 703-487-4650).

    Protocols approved by the Organization for Economic .
Cooperation and Development (OECD) are also acceptable if
the OECD-recommended test standards conform to those specified
in the Pesticide Data Requirements regulation (Part 158.70).
Please note, however, that certain OECD standards (such as test
duration, selection of test species, and degradate
identification which are environmental fate requirements) are
less restrictive than those in the EPA Assessment Guidelines
listed above.  When using the OECD protocols, they should be
modified as appropriate so that the data generated by the study
will satisfy the requirements of Part 158.  Normally, the Agency
will not extend deadlines for complying with data requirements
when the studies were not conducted in accord with acceptable
standards.  The OECD protocols are available from OECD, 1750
Pennsylvania Avenue, N.W., Washington, D.C. 20006.

G.  Procedures for requesting a change in test protocol•

     If you will generate the required data and plan to use test
procedures which deviate from 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.
                                33

-------
     You should submit your protocols before beginning testing,
because the Agency will not ordinarily accept as sufficient
studies using unapproved protocols.  A request for protocol
approval will not extend the timeframe for submittal of the
data, nor will extensions generally be given to conduct
studies due to submittal of inappropriate protocols.  The
Agency will respond in writing to your request for protocol
approval or change.

H.  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.

     EPA will view failure to request an extension before
the data submittal 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.  The Agency will  .
respond in writing to any requests for extension of time.
                                                               «
I.  Data Format anfl Reporting Requirements

    All data submitted in response to this Notice must comply
with EPA requirements regarding the reporting of data,
including the manner of reporting, the completeness of results,
and the adequacy of any required supporting (or raw) data,
including, but not limited to, requirements referenced or
included in this Notice or contained in PR Notice 86-5 (issued
July 29, 1986).  All studies must be submitted in the form of a
final report; a preliminary report will not be considered to
fulfill the submittal requirement.


J.  Existing stocks prqvision upon suspension or cancellation.

     The Agency has determined that if a registration is
suspended for failure to respond to a OCX request under
FIFRA sec. 3(c)(2)(B), an existing stocks provision for the
registrant 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


                                34

-------
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:

     1.  Explanation 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 FIFRA.
                               35

-------
     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.  If you have an end use product, the data are
listed in Table C.  As noted earlier, the Agency has decided
that it will not routinely require product-specific data for end
use products at this time.  Therefore, Table C may not be
contained in this Registration Standard; if there is no Table C,
you are not required to submit the data 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.0 through J.  You should note, however, that
product chemistry data are required for every product, and the
only acceptable responses are options VI.0.1. (submit data) or
VI.0.6.(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.                  .
                                36

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

     FIFRA 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 CFR
156.10 (see Appendix II - LABELING and SUMMARY).  In addition,
labeling language specific to products containing this pesticide
is specified in Section IV.D of this Registration Standard.
Responses to this Registration Standard must include draft
labeling for Agency review.

     Labeling must be either typewritten text on 8-1/2 x 11 inch
paper or a mockup of the labeling suitable for storage in 8-1/2
x 11 files.  Draft labeling must indicate the intended colors of
the final label, clear indication of the front panel of the
label, and the intended type sizes of the text.

     If you fail to submit revised labeling as required,
which complies with 40 CFR 156.10 and the specific instructions
in Section IV.D., EPA may seek to cancel the registration of
your product under FIFRA sec. 6.
                                37

-------
               IX.  INSTRUCTIONS FOR SUBMTTTAL

     All submittals in response to this Registration standard
must be sent to the following address:

     Office of Pesticide Programs
     OPP Mailroom (TS-767C)
     Environmental Protection Agency
     401 M St., SW
     Washington, D.C.  20460

     Attn:  MCPP Registration Standard

     All submittals in response to this Registration standard
are non-fee items, including 90-day responses, protocols and
waiver requests, data, and revised labeling.  Submittals must be
clearly identified as being in response to the Registration
Standard.  Under no circumstances may Registration Standard
responses be combined with other types of filings for which fees

I.  DATA APPENDICES
        41

-------
                           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 formulation11
     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 era 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 Prot 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
                               42

-------
                          TGUIDE-2
     F - Greenhouse, non-food
     G » Forestry
     H = Domestic outdoor
     I » Indoor

Any other designations will be defined in a footnote to the
table.

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.

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

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.
                             43

-------
                           TGUIDE-3
6.   Must additional data b«* ^iifomitted? (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 e
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 f«">r fflTbffllffSJQn (Column 7).  If column t
requires that data be submitted, this column indicates when
the data are to be submitted, based on the issuance date of
the Registration 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).

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

      or degrades from the salt or ester  form to the MCPP acid.  Additionally, data on the organic salts or ester part
      of the formulation will be necessary to support  registration.  The rate and completeness of the dissociation or
      degradation reaction are essential  to  the development of the environmental fate profile of each registered MCPP
      chemical form.  The process or processes and the rate at which this reaction occurs as well as any substantial
      side reactions are the target of the environmental fate data requirements.
    2/The hydrolysis data requirement is  only partially satisfied for the acid and potassium salt formulations; the
      requirement is not satisfied for the organic salt/ester forms of MCPP.

       study is not required for the current use patterns.
4/Ihe studies reviewed partially satisfy the adsorption/desorption data requirement for the unaged residues of
  MCPP only (acid and potassium salt formulations) .  Adsorption/desorption data are required for both the unaged
  and aged organic salVester forms of MCPP pesticides.
5/Ihere are no current registered combination or tank mixes for MCPP pesticides.
£/lhe requirement for this study is reserved pending the results of the field dissipation study.

    Note:  Registrants who conduct chronic feeding and/or ohoogenicity studies should inform the Agency in writing of the
           dosage levels planned and their reasons for believing that the highest dose approaches or equals the Maximum
           Tolerated Dose observed in subchronic or range-finding studies, and must also consult with the Agency to
           determine that the appropriate dosage levels are being used in the chronic feeding and/or onoogenicity studies.
           If EPA subsequently determines that the study was conducted using a dosage rate that was too low to assess
           long-term effects, the  study may be deemed not to satisfy the data requirement.
   J/MCPP, by virtue of  its structure or known toxicity, does not require delayed neurotoxicity studies.
   2/This study is not required  for  the registered use patterns.
   3/A Chinese  hamster bone marrow cytogenetics study is required on MCPP acid or MCPP potassium salt.
   4/A dermal teratogenicity  study in the rat may be needed if the results of the dermal absorption study indicate
     significant dermal  absorption.

^/Reentry data are required for commercial turf use.  Data must reflect exposure resulting from harvesting
  and handling treated turf.
•^/Reserved pending registrant submission and Agency evaluation of complete toxicology data base including dermal
  and inhalation toxicity.
4/Sites include commercial home lawns (hose end sprayer, power sprayer, back pack); and commercial turf (ground boom).
  Protocols are to be submitted in 6 months.
5/Spray drift data are not required under this Standard at this time because MCPP does not meet the human or
  phytotoxicity requirement under §158.142.

   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 9AV~ RESTRICTED USE CLASSIFICATION - FIFRA sec. 3(d)
requires 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 IV
indicates why the product has been classified for restricted
use); or (2) reserved any classification decision until
appropriate data are submitted.
                                  75

-------
                           SUMMARY- 4

   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
classification 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.

      .fication Label i:

   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 156. 10 (h) (1)
            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.
                                   74

-------
                           SUMMARY-5

        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 simultaneously.
        Note that the products will be assigned separate
        registration numbers.


   Item 9B.  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.

   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.

-------
                           SUMMARY-6

   Item 10B.  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 IOC.  DIRECTIONS FOR USE - Directions for use must be
stated in terms which can be easily read and understood by the
average person likely to sue 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 156.10]

                      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.
                                    76

                              STOR-1

               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.

                            PEST/DIS-1

                 PESTICIDE DISPOSAL INSTRUCTIONS

The  label of all products, except those intended solely for
domestic use, must bear explicit instructions about pesticide
disposal.  The statements listed below contain the exact wording
that must appear on the label of these products:

1.   The labels of all products, except domestic use, must

III.   BIBLIOGRAPHY APPENDICES
          84

-------
                Guide to Use of This Bibliography

1.   CONTENT  OF  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 OF  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 can be described viith 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 OF  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  explanation.    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.

4.   FORM OF 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.

          a.    Author.    Wheneve.r  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.
                                  85

-------
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  following  elements  describing   the earliest
     known submission:
                       'i
     (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.
