II. Introduction

A. What Action is the Agency Taking?

     The Agency is initiating the EDSP Tier 1 screening for the first 
group of 67 chemicals by issuing test orders from October 29, 2009, 
through February 26, 2010. Details on the status of the orders will be 
provided on EPA's website at http://www.epa.gov/endo with information, 
including the order issuance date, the recipient(s) of the order, each 
order recipient's response and the order due date. EPA intends to 
update the list with subsequent publications and postings as 
appropriate. This public listing is provided to invite the public to 
identify additional entities who should receive the FFDCA section 
408(p) test order. The commenters could either identify themselves or 
another person as additional candidates (with proper substantiation) 
for receipt of a FFDCA section 408(p) test order by contacting the 
person listed under FOR FURTHER INFORMATION CONTACT.

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

    FFDCA section 408(p)(1) 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

[[Page 54424]]

similar to an effect produced by a naturally occurring estrogen, or 
such other effects as [EPA] may designate.'' (21 U.S.C. 346a(p)). 
Section 408(p)(3) specifically requires that the Administrator ``shall 
provide for the testing of all pesticide chemicals.'' (21 U.S.C. 
346a(p)(3)).
    Section 201 of FFDCA defines ``pesticide chemical'' as ``any 
substance that is a pesticide within the meaning of [FIFRA], including 
all active and inert ingredients of such pesticide.'' (21 U.S.C. 
231(q)(1)).
    Section 408(p)(5) of FFDCA provides that the Administrator shall 
issue an order to a registrant of a substance for which testing is 
required under this subsection, or to a person who manufactures or 
imports a substance for which testing is required under this 
subsection. The order shall require the recipient to conduct testing in 
accordance with the screening program, and to submit information 
obtained from the testing to the Administrator, within a reasonable 
time period that the Administrator determines is sufficient for the 
generation of the information.
    Section 3(c)(2)(B) of FIFRA provides that registrants must submit 
additional data, upon notification that the Administrator has 
determined that additional data are required to maintain an existing 
pesticide registration. (7 U.S.C. 136a(c)(2)(B)). In light of the 
directive in section 408(p)(3) of FFDCA that EPA is to provide for the 
endocrine screening of all pesticide chemicals, EPA considers that such 
data have been statutorily determined to be necessary to maintain an 
existing pesticide registration.

III. Background

    EPA developed the 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 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 initiated 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, 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. Based on these 
recommendations, EPA developed a two-tiered assessment approach for 
these chemicals, 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 implemented its EDSP in three major parts.
    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 EPA 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 EDSP Tier 1 screening assays were 
peer reviewed by independent experts and by the FIFRA Scientific 
Advisory Panel (SAP) during a public meeting on March 25-27, 2008. 
Details on the validation and peer review process for the assays as 
well as the peer review reports can be found on EPA's website at http:/
/www.epa.gov/scipoly/oscpendo/pubs/assayvalidation/index.htm. The FIFRA 
SAP report is available at http://www.epa.gov/scipoly/sap/meetings/
2008/march/minutes2008-03-25.pdf. Elsewhere in this issue of the 
Federal Register, EPA is issuing the final Tier 1 battery composed of 
the validated assays. The Tier 1 battery protocols can be found in the 
corresponding docket EPA-HQ-OPPT-2009-0634 or the website at http://
www.epa.gov/oppts (select ``Test Methods & Guidelines''). 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 under the EDSP 
in the Federal Register of September 27, 2005 (70 FR 56449) (FRL-7716-
9), 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 public comments and Agency responses can be 
found in the associated docket EPA-HQ-OPPT-2004-0109. In April 2009, 
EPA published in the Federal Register its final list of the first group 
of chemicals to be screened under EDSP. The first group of 67 chemicals 
identified for screening 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. More information on 
EPA's priority setting approach for selection of the first group of 
chemicals for the EDSP is available at http://www.epa.gov/scipoly/
oscpendo/prioritysetting.
    The first group of chemicals to be screened consists of chemicals 
that section 408(p) of FFDCA requires be screened, i.e., pesticide 
active ingredients and chemicals used as pesticide inert ingredients 
(also known as other ingredients). 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

[[Page 54425]]

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.
    3. Procedures. EPA published a document in the Federal Register of 
December 13, 2007 (72 FR 70842) (FRL-8340-3), that describes the 
proposed procedures that EPA would use to issue orders, the proposed 
procedures that order recipients would use to respond to the order, how 
data protection and compensation would be addressed in the test orders, 
and other related proposed 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). On April 15, 2009, the Agency published 
the final policies and procedures and related documents in the Federal 
Register ((74 FR 17560) (FRL-8399-9), (74 FR 17579) (FRL-8399-7), and 
(74 FR 17477) (FRL-8412-2)). EPA generally intends to adopt these 
procedures for initial screening of chemicals under the EDSP, including 
the statutory requirements associated with and format of the test 
orders, as well as EPA's procedures for fair and equitable sharing of 
test costs and handling of confidential data (docket number EPA-HQ-
OPPT-2007-1080).

    Details on the status of the orders will be provided on EPA's 
website at http://www.epa.gov/endo with information, including the 
order issuance date, the recipient(s) of the order, the order 
recipient's response to the order, and the order due date.

V. Submission of Other Scientifically Relevant Information by 
Interested Parties

    The Agency published the final policies and procedures and related 
documents in the Federal Register of April 15, 2009 ((74 FR 17560), (74 
FR 17579), and (74 FR 17477)); as part of those documents, EPA 
discussed its policies relating to the submission of other 
scientifically relevant information in satisfaction of a test order. As 
explained at greater length in those documents, if recipients of the 
FFDCA section 408(p) test orders choose to cite or submit existing 
data, (i.e., other scientifically relevant information (OSRI)), along 
with a rationale that explains how the cited or submitted study 
satisfies the Tier 1 test order in lieu of developing new data, EPA 
will determine whether the information can be used to satisfy part or 
all of the Tier 1 order and/or otherwise inform the Tier 1 
determination. Existing data may include data that has already been 
generated using the assay(s) specified in the order, or other 
scientifically relevant information. Other scientifically relevant 
information is information that informs 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 (e.g., information that identifies substances 
as having the potential to interact with the estrogen, androgen, and/or 
thyroid system(s); information demonstrating whether substances have an 
effect on the functioning of the endocrine system). Other 
scientifically relevant information may either be functionally 
equivalent to information obtained from the Tier 1 assays--that is, 
data from assays that perform the same function as EDSP Tier 1 assays--
or may include data that provide information on a potential consequence 
or effect that could be due to effects on the estrogen, androgen or 
thyroid systems. Some other scientifically relevant information may be 
sufficient to satisfy part or all of the Tier 1 order and/or otherwise 
inform the Tier 1 determination.
    The Agency has written a paper entitled ``EPA's Approach for 
Considering Other Scientifically Relevant Information (OSRI) under the 
EDSP'' (see www.regulations.gov and search for docket number EPA-HQ-
OPPT-2007-1080-0032). This paper was developed to provide guidance to 
EPA staff and managers who will review the responses to Tier 1 test 
orders issued under the EDSP, and may also be of interest to parties 
considering whether to submit OSRI to EPA. This paper is intended only 
to provide general guidance and is not binding on either EPA or any 
outside parties. Anyone, including members of the general public, may 
provide OSRI, and the Agency will assess the information for 
appropriateness on a case-by-case basis to determine whether the 
information can be used to satisfy part or all of the Tier 1 order and/
or otherwise inform the Tier 1 determination.
    Persons other than those receiving testing orders who would like to 
submit OSRI on chemicals subject to test orders should include the 
following information:
     The submitter's contact information.
     The name of the program (i.e., Endocrine Disruptor 
Screening Program (EDSP).
     The name of the chemical to which the information applies.
     The citation of the study and/or a copy of the study, if 
possible.
     The order number(s) to which the information applies.
     A rationale that explains how the cited or submitted 
study(ies) satisfies all or some portion of the Tier 1 order.
In order for this information to be given timely consideration, the 
information should be submitted on the same time frame as the response 
to orders, i.e. this information should be submitted as a comment to 
the docket for this action (EPA-HQ-OPP-2009-0634) within 90 days of the 
issuance date of the orders for a given chemical. The details about the 
dates of issuance of the orders can be found at www.epa.gov/endo.

VI. Pesticide Inert Ingredients Data Submitters and Suppliers List

    Currently, EPA maintains a list of all data on pesticide active 
ingredients that supports registration of products containing the 
active ingredient, along with contact information for the submitters 
(i.e., owners) of the data, known as the ``Data Submitters List.'' The 
Agency published the final policies and procedures and related 
documents in the Federal Register on April 15, 2009 ((74 FR 17560), (74 
FR 17579), and (74 FR 17477)) describing EPA's intention to establish a 
Pesticide Inert Ingredients Data Submitters & Suppliers List (PIIDSSL) 
which is similar to the ``Data Submitters List.'' The purpose of the 
PIIDSSL is to identify any entity who has submitted compensable data on 
a pesticide inert ingredient in response to a test order issued under 
section 408(p) of FFDCA. Pursuant to FIFRA section 3(c)(1)(F), when a 
applicant's product contains a pesticide inert ingredient on the 
PIIDSSL, EPA intends to require the applicant to identify the source of 
the pesticide inert ingredient. If the applicant's source does not 
appear on the PIIDSSL, EPA intends to require the applicant either to 
switch to a source on the PIIDSSL; offer to pay compensation to the 
original data submitter(s) on the PIIDSSL; or generate

[[Page 54428]]

their own data to support their application.
     The PIIDSSL can be found on EPA's website at www.EPA.gov/
DataSubmittersList or a link to it can be found at www.epa.gov/endo.
