ENVIRONMENTAL PROTECTION AGENCY
PESTICIDE CHEMICAL ACTIVE INGREDIENTS
REGISTRATION STANDARDS RANKING SCHEME RESULTS
AGENCY: Environmental Protection Agency (ETA).
ACTION: Notice.
SUMMARY: Under the Federal Insecticide, Fungicide and Rodenticide
Act (FIPRA), EPA is required to review the approximately 40,000
pesticide products currently registered in order to' determine
whether they pose unreasonable effects on man or the environment.
EPA issued an Advanced Notice of Proposed Rulemaking (ANPR)
published in the FEDERAL REGISTER of December 26, 1979 (44 PR
7 6311) entitled "Registration Standards for the Registration of
Pesticides" and indicated that it would review these products
based on their active ingredients. This informational notice is
intended to' provide' "Thfcerested parties with the order in which EPA
has prioritized the various pesticide active ingredients to be
reviewed undet the'Registration Standard Program.

SUPPLEMENTARY INFORMATION: This document describes the results of
EPA's proposed registration standard ranking scheme to order the
registration standard reviews of pesticide active ingredients
based on their production and exposure.
The more than 600 active ingredients have been grouped into
"clusters" according to the sites on which they are applied, e.g.,
herbicides used on cotton and soybeans. Once the chemicals were
assigned to clusters, a ranking equation, based on chemical
production and exposure, was used to assign point values to
clusters. Clusters with high point values, i.e., high exposure
and production, were ranked high priority and will be reviewed
ahead of lower ranked clusters. EPA has reserved the right to
bypass the ranking order for single chemicals or entire clusters
when such action is warranted based on new data, public concern,
or other circumstances. Although the ranking listed here is the
review order foreseen at this time, minor revisions to the
ordering may be made in the future for workload balancing, data
availability, or other reasons.

-------
A detailed discussion of the ranking scheme was published in the
FEDERAL REGISTER OP November 14, 1980 (45 FR 75488).
EPA plans to implement the cluster approach to review
registration standard chemicals in FY *82. The last nine
chemicals identified for initial registration standard review in
the FEDERAL REGISTER of April 18, 1980 (45 FR 26370) will not be
reviewed at this time, except for tebuthiuron. Instead, they
will be reviewed as part of the cluster in which they appear.
Comments received in response to the proposed registration
standard ranking scheme prompted a re-review of the ranking scheme
and master chemical list by EPA. The following addresses the
major comments and reflects changes that EPA has made as a result
of these comments.
Some commenters indicated that the cluster concept is
contrary to the mandate of FIFRA section 3(g) which states "to the
extent appropriate, any pesticide that results in a postharvest
residue in or on food or feed crops, shall be given priority in
the reregistration process." The equation used to estimate
exposure weighs food uses more heavily than non—food uses. For
example, up to 4 points are assigned to each chemical with
tolerances, and all chemicals with agricultural uses automatically
get an additional 2 points. The resulting ranking contained in
this notice demonstrates the effect of this scheme since, of the
first ten clusters, 6 are for food uses. However, it is
inappropriate to review all food uses ahead of all non-food uses
because some non-food uses have high exposure levels, e.g.,
termiticides^

Concern was raised that SPA intends to use these clusters in
the Rebuttable Presumption Against Registration (RPAR) process.
The cluster system was developed to prioritize chemicals for
registration standard review. However, review of chemicals in
clusters will help expedite an RPAR review on a chemical growing
out of the registration standard review since risk data on many
alternative chemicals will have already been assembled and
analyzed.
Some commenters felt that the cluster approach is not equit-
able to registrants unless each chemical has only one use. This
is true of any reasonable approach to prioritize the review of
chemicals based on use. Recognizing this problem, EPA attempted
to alleviate some of the inequity by using the chemical's major
use to determine its cluster assignment. However, it is most
efficient for EPA to review all uses of a chemical simultaneously.
EPA recognizes the limitations of this approach but feels that the
advantages of this approach outweigh this disadvantage.
Questions were raised regarding the equation used to assign
point values to chemicals. EPA recognizes the limitations of the
equation that has been selected and that some factors could be
considerably more broad or specific. EPA's objective in estab-
lishing the equation was to differentiate between high and low
production/exposure chemicals without expending considerable
EPA resources in the prioritization effort. An equation that is
far more broad would not have yielded adequate information to make
a determination as to priority. An equation that is far more

-------

specific would require research not dissimilar from that done for
a full risk/benefit review, thereby expending more resources to
establish the ranking than is warranted.
In addition to these major concerns, commenters raised
questions as to inclusion, omission, and cluster assignments of
a number of chemicals. EPA's re-review of the master chemical list
resulted in the deletion of a number of inert ingredients that had
inadvertently been included as active ingredients. These are:
alkyl monoethanol amide, aluminum chloride, aluminum hydroxy
benzene sulfonate, aluminum powder, amyl acetate (banana oil),
castor oil, chlorothene (1,1,1-trichloroethane), dimethyl
phthalate, EDTA, ethylenediamine, eucalyptus, fumaric acid,
glycolic acid (sodium glycolate), isooctyl phenoxy polythoxy
ethanol, lemongrass oil, menthol, methyl salicylate (wintergreen),
morpholine, potassium bisulfate, soap, sodium acetate, sodium
chloride, sodium diacetate, sodium lauryl sulfate, sodium
N-raethyl-N-oleoyltaurate, sodium phosphates, sodium sulfate,
sodium thiosulfate, triethanolamine salt of lauryl sulfate,
trisodium nitrilotriacetate, and trisodium phosphate.
Another group of chemicals was deleted from the master list
due to information that the chemicals have no registrations.
These chemicals are: calcium cyanamide, chlorobromuron,
profenofos (curacron®) , and tridemorph (calixin®^.

-------
-6-
Several chemicals were added to the master list that had, in
the draft, been overlooked. These are: amdro (1-8) , BKLFI2 (R-4),
(fO
bolex** (1-1), beta-bromo-beta-nitrostyrane (R-3), cycocel (R-10),
1,3-dichloropropene (1-9), didecyl dimethyl ammonium chloride
(R-8), 3,5-dimethyl tetrahydro-2H-l,3,5-thiadiazine-2-thione
(terramycin) (R-l), dioctyl dimethyl ammonium chloride (R-8),
fluoridamid (R-10), hydrogen peroxide (R-8), mefluidide (R-10),
octyl decyl dimethyl ammonium chloride (R-8), ridomil® (F-10),
sodium dimethyldithiocarbamate (R-2), 3,3,4,4-tetrachlorotetrahydro
thiophene 1,1-dioxide (R-2), tri(n-butyl) tin oxide (R-2), and
uniquat CB 50 (R-8).
In addition, a few chemicals have been reassigned to clusters
that more accurately reflect the chemical's major use sites.
These are: chloroxuron (H-7 to H-9), diamidaphos (1-13 to 1-9),
dipropetryn (H-4 to H-3), norflurazon (H-4 to H-3), prometon
(praxnitol) (H-10 to H-7), prometryn (H-10 to H-9), arid trans-1,2 bis
(propylsulfonyl) ethylene (F-5 to R-l).
