Final List of Initial Pesticide Active Ingredients and Pesticide 
Inert Ingredients to be Screened Under the Federal Food, Drug, and 
Cosmetic Act

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: Section 408(p) of the Federal Food, Drug, and Cosmetic Act 
(FFDCA) directs EPA to develop a chemical screening program using 
appropriate validated test systems and other scientifically relevant 
information to determine whether certain substances may have hormonal 
effects. In September 2005, EPA published its approach for selecting 
the initial list of chemicals for which testing will be required under 
the Endocrine Disruptor Screening Program (EDSP) and in June 2007, EPA 
published the draft list of the first group of chemicals proposed for 
screening in the Agency's EDSP. This document presents the final list 
of the first group of chemicals that will be screened in the Agency's 
EDSP. The list was produced using the approach described in the 
September 2005 notice and considers comments received in response to 
the June 2007 draft list. The list includes chemicals that the Agency, 
in its discretion, has decided should be tested first, based upon 
exposure potential. The Agency deleted 6 chemicals from the original 
list of 73 based upon recent information showing that the chemicals are 
no longer expected to be found in 3 exposure pathways. The first group 
of 67 chemicals identified for testing includes pesticide active 
ingredients and High Production Volume (HPV) chemicals used as 
pesticide inert ingredients (also known as other ingredients). This 
list should not be construed as a list of known or likely endocrine 
disruptors. Nothing in the approach for generating the initial list 
provides a basis to infer that by simply being on this list these 
chemicals are suspected to interfere with the endocrine systems of 
humans or other species, and it would be inappropriate to do so. This 
document does not describe other aspects of the EDSP such as the 
administrative procedures EPA will use to require testing, which is 
addressed in a separate notice published in today's Federal Register.

II. Introduction

A. What Action is the Agency Taking?

    EPA is announcing the final list of the first group of chemicals 
that will be screened in the Agency's Endocrine Disruptor Screening 
Program (EDSP) based on the approach described in the Federal Register 
notice of September 27, 2005 (70 FR 56449) (FRL-7716-9), and 
consideration of comments received on the draft list of chemicals 
published in the Federal Register notice of June 18, 2007 (72 FR 33486) 
(FRL-8129-3). The approach focused on human exposure-related factors 
rather than a combination of exposure- and effects-related factors. The 
approach did not include a literature search for or consideration of 
any data on potential endocrine effects. Because EPA developed this 
list of chemicals based upon exposure potential, it should not be 
construed as a list of known or likely endocrine disruptors, and it 
would be inappropriate to do so. Nothing in the approach for generating 
the initial list provides a basis to infer that by simply being on this 
list these chemicals are suspected to interfere with the endocrine 
systems of humans or other species.
    The first group of chemicals to be tested consists of chemicals 
that section 408(p) of the Federal Food, Drug, and Cosmetic Act (FFDCA) 
requires be screened, i.e., pesticide active ingredients and chemicals 
used as pesticide inert ingredients (also known as other ingredients) 
that are also HPV chemicals. EPA anticipates that it may, in the 
future, modify its approach to selecting chemicals for screening. 
Information and factors that EPA may consider in selecting chemicals 
could include: Public input; the results of testing chemicals on the 
initial list; management considerations to increase the integration of 
screening with other regulatory activities within the Agency; 
implementation considerations flowing from a decision to extend 
screening to additional categories of chemicals (e.g., non-pesticide 
chemical substances); and the availability of new priority setting 
tools (e.g., High Throughput Pre-screening or Quantitative Structure 
Activity Relationships models). More information on EPA's priority 
setting approach is available at http://www.epa.gov/scipoly/oscpendo/pubs/prioritysetting.
    EPA's general focus in the approach for the initial list was on 
pesticide active ingredients and inert ingredients with relatively 
greater potential for human exposure. The emphasis on human exposure 
does not necessarily mean that the list will not contain substances 
that may not also have potentially high levels of environmental 
exposure to ecological receptors. This Federal Register document 
identifies the chemicals that were removed from the draft list and 
presents the final list of the first group of chemicals that will be 
screened in the Agency's EDSP in alphabetical order. This document does 
not describe other aspects of the EDSP such as the administrative 
procedures EPA will use to require testing, the validated tests and 
battery that will be included in the EDSP, or the timeframe for 
requiring the testing or receiving the data. These topics will be 
addressed in separate notices published in the Federal Register, with 
the administrative procedures described in a separate notice published 
in today's Federal Register.

B. What is the Agency's Authority for Taking this Action?

    Section 408(p) of FFDCA requires EPA to ``develop a screening 
program, using appropriate validated test systems and other 
scientifically relevant information, to determine whether certain 
substances may have an effect in humans that is similar to an effect 
produced by a naturally occurring estrogen, or such other endocrine 
effect as [EPA] may designate.'' (21 U.S.C. 346a(p)). The statute 
generally requires EPA to ``provide for the testing of all pesticide 
chemicals.'' (21 U.S.C. 346a(p)(3)). However, EPA is authorized to 
exempt a chemical, by order upon a determination that ``the substance 
is anticipated not to produce any effect in humans similar to an effect 
produced by a naturally occurring estrogen.'' (21 U.S.C. 346a(p)(4)). 
``Pesticide chemical'' is defined as ``any substance that is a 
pesticide within the meaning of the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA), including all active and inert ingredients of 
such pesticide.'' (21 U.S.C. 321(q)(1)).

III. Background

    EPA developed its EDSP in response to the Congressional mandate in 
section 408(p) of FFDCA to ``develop a screening program. . .to 
determine whether certain substances may have an effect in humans that 
is similar to an effect produced by a naturally occurring estrogen, or 
such other endocrine effects as [EPA] may designate'' (21 U.S.C. 
346a(p)). When carrying out the program, the statute requires EPA to 
``provide for the testing of all pesticide chemicals.'' The statute 
also provides EPA with discretionary authority to ``provide for the 
testing of any other substance that may have an effect that is 
cumulative to an effect of a pesticide chemical if the Administrator 
determines that a substantial population may be exposed to such a 
substance.'' In addition, section 1457 of the Safe Drinking Water Act 
(SDWA) provides EPA with discretionary authority to provide for 
testing, under the FFDCA section 408(p) screening program, ``of any 
other substances that may be found in sources of drinking water if the 
Administrator determines that a substantial population may be exposed 
to such substance.''
    EPA initially set forth the EDSP in the August 11, 1998 Federal 
Register notice (63 FR 42852) (FRL-6021-3), and solicited public 
comment on the program in the December 28, 1998 Federal Register notice 
(63 FR 71542) (FRL-6052-9). The program set forth in these notices was 
based on the recommendations of the Endocrine Disruptor Screening and 
Testing Advisory Committee (EDSTAC), which was chartered under the 
Federal Advisory Committee Act (FACA), 5 U.S.C. App.2, section 9(c). 
The EDSTAC was comprised of members representing the commercial 
chemical and pesticides industries, Federal and State agencies,

[[Page 17581]]

worker protection and labor organizations, environmental and public 
health groups, and research scientists.
    EDSTAC recommended that EPA's program address both potential human 
and ecological effects; examine effects on estrogen, androgen, and 
thyroid hormone-related processes; and include non-pesticide chemicals, 
contaminants, and mixtures in addition to pesticides (Ref. 1). Based on 
these recommendations, EPA developed a two-tiered approach, referred to 
as the EDSP. The purpose of Tier 1 screening (referred to as 
``screening'') is to identify substances that have the potential to 
interact with the estrogen, androgen, or thyroid hormone systems using 
a battery of assays. The purpose of Tier 2 testing (referred to as 
``testing'') is to identify and establish a dose-response relationship 
for any adverse effects that might result from the interactions 
identified through the Tier 1 assays. EDSTAC also recommended that EPA 
establish a priority-setting approach for choosing chemicals to undergo 
Tier 1 screening. EPA described this approach in the Federal Register 
of September 2005. More information on EPA's priority setting approach 
for the EDSP is available at http://www.epa.gov/scipoly/oscpendo/prioritysetting.
    EPA currently is implementing its EDSP in three major parts that 
are being developed in parallel.
    1. Assay validation. Under FFDCA section 408(p), EPA is required to 
use ``appropriate validated test systems and other scientifically 
relevant information'' to determine whether substances may have 
estrogenic effects in humans or other endocrine effects as the 
Administrator may designate. Validation is defined as the process by 
which the reliability and relevance of test methods are evaluated for 
the purpose of supporting a specific use. The proposed EDSP Tier 1 
screening battery of assays was presented to the FIFRA Scientific 
Advisory Panel (SAP) during a public meeting on March 25-27, 2008. The 
FIFRA SAP report covering the meeting is available at http://www.epa.gov/scipoly/sap/meetings/2008/march/minutes2008-03-25.pdf. The 
final Tier 1 battery will be announced in a separate Federal Register 
document that the Agency anticipates issuing in spring 2009. EPA is 
also in the process of developing and validating Tier 2 tests. The 
status of each assay can be viewed on the EDSP website in the Assay 
Status table: http://www.epa.gov/scipoly/oscpendo/pubs/assayvalidation/status.htm.
    2. Priority setting. EPA described its priority setting approach 
for the first group of pesticide chemicals to be tested in the Federal 
Register of September 2005, and proposed the draft list of initial 
chemicals for review and public comment in the Federal Register notice 
of June 18, 2007 (72 FR 33486) (FRL-8129-3). The Agency is responding 
to the public comments in a separate document (Ref. 2) posted in the 
docket that was established for this action (EPA-HQ-OPPT-2004-0109). 
This document today announces the final list of initial chemicals to 
undergo Tier 1 screening. More information on EPA's priority setting 
approach for the EDSP is available at http://www.epa.gov/scipoly/oscpendo/prioritysetting.
    3. Procedures. EPA intends to commence Tier 1 screening of the 
first group of pesticide chemicals by issuing test orders under FFDCA 
section 408(p) to chemical companies identified as the manufacturer or 
processor of the identified chemicals and/or the pesticide registrants. 
EPA published draft policies and procedures in the Federal Register 
notice of December 13, 2007 (72 FR 70842) (FRL-8340-3), that describes 
the procedures that EPA will use to issue orders, the procedures that 
Order recipients would use to respond to the order, how data protection 
and compensation will be addressed in the test orders, and other 
related procedures or policies. In addition, EPA developed a draft 
template for the test order and a draft information collection request 
(ICR) to obtain the necessary clearances under the Paperwork Reduction 
Act (PRA). Elsewhere is this issue of the Federal Register, the Agency 
is publishing the final policies and procedures, and the announcement 
of the ICR's submission to OMB.
    Based on the current timing for each of the three major parts of 
the EDSP, the Agency intends to initiate the EDSP Tier 1 screening for 
the first group of pesticide chemicals by issuing test orders in 2009. 
This document deals only with the final list of chemicals initially 
selected to go through screening in the Tier 1 assays.

IV. Development of the Initial List of Chemicals

    The development of the initial list of chemicals is described in 
detail in the September 2005 and the June 2007 Federal Register 
notices.
Comments on the Final List
    EPA received comments on the proposed initial list including 
suggestions for additional chemicals, questions regarding the need for 
Tier 1 screening data, the future chemical selection approach, and 
claims for removal of chemicals from the list. One of the main concerns 
was whether and how EPA would consider existing data in determining 
what screening assays were necessary. Although EPA does not currently 
intend to tailor test orders based on existing information, as 
articulated in the Reponse to Comments on the Draft List of Initial 
Pesticide Active Ingredients and Pesticide Inert Ingredients to be 
Screened under the Federal Food, Drug, and Cosmetic Act (Ref. 2), EPA 
will provide a mechanism whereby test order recipients and the public 
can provide information on specific chemicals for which test orders are 
issued. A test order recipient can elect to cite or submit existing 
data the recipient believes can be used to satisfy part or all of the 
Tier 1 Order and/or otherwise inform the determination as to whether 
the substance may have an effect that is similar to an effect produced 
by a substance that interacts with the estrogen, androgen and/or 
thyroid hormonal systems. In order for EPA to review the submission in 
a timely manner, in submitting or citing existing data, the order 
recipient should consider providing an explanation of the relevance of 
the data to the order, including, where appropriate, a cogent and 
complete rationale for why it believes the information is sufficient to 
satisfy part or all of the Tier 1 Order. The recipient's response to 
test orders for Tier 1 assays will be evaluated by EPA to determine 
whether the cited data can be used to satisfy the order and/or 
otherwise inform the Tier 1 determination. This will require a case-by-
case determination of whether the information submitted is of high 
quality and achieves the objective of Tier 1. This approach is 
consistent with ensuring effective and efficient use of societal and 
government resources in generating and reviewing data, as well as 
minimizing the use of animals in regulatory testing, to achieve the 
information base needed to support a specified objective.
    These comments have been addressed in a document, entitled Reponse 
to Comments on the Draft List of Initial Pesticide Active Ingredients 
and Pesticide Inert Ingredients to be Screened under the Federal Food, 
Drug, and Cosmetic Act (Ref. 2), available in the docket for this 
action under docket ID number EPA-HQ-OPPT-2004-0109. In addition, the 
Agency has written a paper entitled EPA's Approach for Considering 
Other Scientifically Relevant Information (OSRI) under the Endocrine 
Disruptor Screening Program. This paper was developed by EPA to provide 
guidance to EPA staff and managers who will be reviewing the responses 
to Tier 1 Orders issued under the EDSP, and may also be of interest to

[[Page 17582]]

parties considering whether to submit other scientically relevant 
information to EPA. This paper provides general guidance and is not 
binding on either EPA or any outside parties. Anyone may provide other 
scientifically relevant information, and the Agency will assess the 
information for appropriateness on a case-by-case basis, responding to 
the submitter in writing, and making EPA's determination publicly 
available. A copy of this paper has been placed in the Docket for the 
Policies and Procedures for the Initial EDSP Screening (Docket ID 
number EPA-HQ-OPPT-2007-1080).

V. The Final List of Initial Pesticide Active Ingredients and Pesticide 
Inert Ingredients (also known as other ingredients) to be Considered 
for Screening under the FFDCA

A. Chemicals Removed from the Draft List of Proposed Chemicals for 
Initial Screening

    No HPV pesticide inert ingredients were removed. Six pesticide 
active chemicals were removed from the draft list of proposed chemicals 
for initial screening that resulted in this final list. Two of the 
chemicals, azinphos-methyl and fenvalerate, were removed from the list 
because all uses of these pesticides have ended or will end before Tier 
2 data could be generated in 2012. The remaining four chemicals were 
removed based on a reassessment of their uses that confirmed that they 
would only be expected to be present in two, instead of three, exposure 
pathways (i.e., the criterion for selecting chemicals for the initial 
list was the presence of the chemical in at least three of the four 
exposure pathways where the food and occupational exposure pathways 
were represented). Specifically, aldicarb, allethrin, dichlorvos, and 
methiocarb, were removed from the initial list because changes in their 
use and application methods has eliminated the potential for exposure 
in one or more pathways. As described in the September 2005 and June 
2007 Federal Register notices, higher occupational exposure was based 
on the potential for agricultural workers to come into contact with a 
pesticide residue after its application (e.g., a worker pruning fruit 
trees or harvesting a crop). For occupational exposure, EPA relied on 
databases that assessed the exposure potential for workers who might 
enter a field or orchard after treatment with pesticides. In two cases 
(aldicarb and methiocarb), EPA regulation has either eliminated 
specific uses or changed the method of application which has eliminated 
or reduced the potential for post-application exposure below the 
threshold described in the previous Federal Register notices (September 
2005 and June 2007) where EPA identified 14 work activities/crop 
categories (e.g., tree fruit crops) having the highest transfer 
coefficients. In the case of aldicarb, the pesticide can only be 
applied by soil incorporation while in the case of methiocarb, the 
remaining agricultural uses are granular applications in nurseries and 
greenhouses. There are currently no registered uses of dichlorvos that 
will result in occupational exposure pathways associated with the 
selected 14 work activities/crop categories having the highest transfer 
coefficients. Finally, current registrations for allethrin and 
methiocarb no longer include uses on food crops. Since these four 
chemicals no longer meet the listing criteria, they are being deleted 
from the initial list of chemicals to be screened. However, it should 
be noted that all pesticidal chemicals will eventually be screened for 
their potential to interact with the endocrine system as required by 
the statute. (21 U.S.C. 346a(p)(3)).
    Table 1 presents an alphabetized list of the six pesticide active 
ingredients that were removed from the original list of 73 chemicals 
recommended for Tier 1 screening in the EDSP and provides the rationale 
for their removal from the list.
