USDA-EPA TOLERANCE REASSESSMENT
ADVISORY COMMITTEE
Meeting Summary
Arlington Hilton & Towers, Arlington, VA
October 20 - 21, 1999
WEDNESDAY, October 20, 1999
Welcome and Introductions
John Ehrmann, Meridian Institute, welcomed participants to the seventh
meeting of the U.S. Department of Agriculture (USDA) - U.S. Environmental
Protection Agency (EPA) Tolerance Reassessment Advisory Committee (TRAC)
which is constituted as a subcommittee to the National Advisory Council on
Environmental Policy and Technology (NACEPT) of EPA. He then initiated a
round of introductions for the benefit of the public. A list of the TRAC
members and materials for the meeting are presented in Docket # OPP00537.
Following the introductions, Dr. Ehrmann turned to Co-Chairs of the
TRAC, Richard Rominger, Deputy Secretary, USDA, and Gary Guzy, General
Counsel, EPA, for opening remarks. Mr. Rominger welcomed everyone to the
last TRAC meeting. He observed that a lot had been accomplished since the
start of the TRAC in implementing the Food Quality Protection Act (FQPA).
Mr. Rominger reviewed some of the milestones of the process including
developing difficult science policies in an open process, applying the
risk assessment and management processes to ensure stakeholder involvement
in shaping regulatory decisions, and learning more about different
perspectives on pesticide regulation in general and the FQPA in
particular. He stated that EPA and USDA learned from the input of the TRAC
and he thanked members for their participation because it is contributing
to successful FQPA implementation. Mr. Rominger observed that, while EPA
met the first deadline for tolerance reviews, there are additional
agricultural concerns and the potential for FQPA to have major impacts on
farmers and others and there is a lot of work still to be done. He
recognized that the framework and processes developed in the TRAC have
worked, and he hoped that EPA and USDA could establish a process for the
future to address the remaining issues such as cumulative risk, with a
similar momentum and spirit as established in the TRAC. Mr. Rominger
stated that he looked forward to input from the TRAC on a future process
that would capitalize on stakeholder expertise. Finally, Mr. Rominger
recognized that there were different interpretations of what transition
means ranging from a plan of action to alter current pest management
practices toward a biologically based system to a shorter term plan to
address chemical-specific issues. At the conclusion of his remarks, Mr.
Rominger turned to Mr. Guzy for opening comments.
Mr. Guzy also welcomed TRAC members to the final TRAC meeting and
thanked them for their commitment to the process. He stated that the
Agency and the Department had benefited from the advice of the TRAC. Mr.
Guzy stressed that, while there had been a number of changes in EPA senior
leadership over the course of the TRAC, EPA remained strongly committed to
TRAC, the processes it has developed, and to continuing a working
relationship with all stakeholders who are concerned with FQPA
implementation. On behalf of Administrator Browner, Mr. Guzy stated that
EPA will continue to devote a significant amount of senior leadership
attention to FQPA issues and they will continue to respond to the concerns
raised by the TRAC and others during the FQPA implementation process. Mr.
Guzy also took the opportunity to reflect on some of the benefits of the
TRAC which included: an increase in the degree of transparency on
tolerance reassessment and risk assessments; a timely process to assess
the tolerances for OPs; and an improved public comment process on nine key
science policies that are important in the tolerance reassessment process.
In addition, Mr. Guzy acknowledged as a direct result of the TRAC process,
the unprecedented cooperation between EPA and the USDA and the enhanced
ability to work cooperatively with all stakeholders to make regulatory
decisions.
Mr. Guzy reviewed the progress on the five objectives summarized in the
memo from Secretary Glickman and Administrator Browner to the Vice
President at the start of the TRAC process. He stated that, while adhering
to the principles of sound science, transparency, stakeholder involvement
and a reasonable transition for agriculture, EPA and USDA first sought
advice from stakeholders in an open and transparent process for tolerance
reassessment. The result was a pilot process for the review of
Organophosphates (OPs) and risk assessments, review and comment on risk
assessments, technical briefings, and opportunities for stakeholder
involvement in risk reduction. Mr. Guzy stated that the second objective
was a policy framework for deciding if there was adequate scientific
information on which to base tolerance reassessment decisions. He
commented that, through the TRAC process, nine science policy areas were
identified and a public process was established to refine the science
principles. The third objective noted by Mr. Guzy was to speed the pace of
decision making to make newer and safer pesticides and new uses of
existing pesticides that meet FQPA requirements available to growers. To
address this need, he noted that EPA put in place a process where
alternatives to older chemicals can be given higher priority for review,
and in collaboration with USDA, information about alternatives can be
disseminated to growers. Mr. Guzy stated that the fourth objective was to
identify common sense strategies for risk reduction while retaining
pesticides of high public value and implementing reasonable phase out
schedules for those pesticides requiring action. In response to this need,
USDA and EPA are working in partnership to determine reasonable time
frames to implement changes in pesticide use that reduce risk. The fifth
objective was to prioritize the OPs that present the greatest risk to
children. He explained that in response, EPA adopted a rigorous schedule
to complete tolerance reassessment and to review individual OPs. Mr. Guzy
summarized by stating that, through the previous TRAC meetings and the
work group meetings, EPA and USDA laid a solid foundation to move forward
on completing the assessment of tolerances required by the FQPA.
Mr. Guzy stated that one of the primary goals of the final meeting of
the TRAC was to hear input on options for the structure of future
stakeholder activities to address pesticide issues. Regardless of the
structure, he noted that EPA would remain committed to following the
principles of sound science, transparency, public involvement, and
reasonable transition for agriculture while progressing to ensure a safe
environment for our children and us. Mr. Guzy then took the opportunity to
describe some of the progress since the last TRAC meeting. He noted that
EPA published six science policy papers in the Federal Register for public
comment; held eight technical briefings on OP's; and shared 14 risk
management options. In addition, Mr. Guzy referenced EPA's actions on
Azinphos Methyl (AZM) and Methyl Parathion (MP) that were consistent with
the principles outlined by the TRAC. He summarized by stating that, for
EPA, the TRAC process has been critical, educational, and has enabled them
to move forward responsively and responsibly to address concerns raised by
stakeholders. In addition, he felt the TRAC helped the members to
understand how EPA regulates and provided EPA with a better perspective on
the needs and concerns of the stakeholders. Once again, Mr. Guzy thanked
TRAC members for their commitment to the process.
Agenda Review and Comments
After the introductory remarks, Dr. Ehrmann reviewed the agenda for the
day as follows:
Review of Recent Activities and Agenda;
EPA Updates on TRAC Issues, including cumulative risk, human studies,
tolerance reassessment progress, and worker risk assessments;
Status Report on OPs;
Transition Issues;
Tolerance Revocations/Channels of Trade; and
Public comment.
He explained that the agenda for the second day of the meeting would
include:
Public Participation Process: Next Steps including options for the
final process, experiences from the pilot process, FY 99 reregistration
eligibility decision documents (REDs), non-OP REDs and the development
process;
Post-TRAC Activities; and
Public comments.
Following the agenda review, Dr. Ehrmann introduced William Jordan,
Office of Pesticide Programs, EPA and Margaret Stasikowski, Director,
Health Effects Division (HED), Office of Pesticides Program (OPP)/EPA for
the presentation on cumulative risk and other science policies.
EPA Updates on TRAC Issues
Cumulative Risk and Other Science Policies
Mr. Jordan began with a presentation on a number of science policies to
assist in setting the context for the discussion on the culmination of the
risk assessment process when looking at a group of chemicals with a common
mechanism: the cumulative risk assessment. He referenced Staff Paper # 41,
TRAC Science Policy, for his presentation and indicated that he
would also include information about some recent activities not contained
in the paper. Details on his presentation and all of the Staff Papers are
presented in Docket # OPP00537. A summary of the highlights from his
presentation is presented below.
Mr. Jordan commented that the science policies are comprehensive and
cover issues from the start of the risk assessment process to the risk
management phase. He noted that EPA was able to make a lot of progress on
the policies thanks to input from the TRAC on identifying key issues of
concern to various stakeholders and the hard work of individuals in the
science divisions, HED, and the Environmental Fate Effects Division (EFED),
as well as other parts of OPP. Mr. Jordan described the paper and stated
that it provides schedules on the release of the various science policy
papers. Among the papers released, Mr. Jordan referenced the most recent
paper on threshold regulation as an example of a document that had been
reviewed by the public and reissued as a revised policy document. He noted
that the document had not yet been announced in the Federal Register. Mr.
Jordan also explained that the drinking water exposure assessment paper,
also reviewed and revised based on public comment, was complete and would
be announced in the Federal Register soon. Other papers in various stages
of review included the guidance on aggregate exposure, cholinesterase
inhibition, the 99.9 percentile policy, and the policy on cumulative risk
assessment. He stated that, when the policy papers on drinking water and
aggregate risk are released, 18 out of the total of 19 policy papers would
have been addressed. He added that, when the papers on drinking water and
threshold regulation are finalized, five out of the 19 papers would have
been finalized. Mr. Jordan thanked TRAC members for their thorough and
thoughtful comments on the papers. Following his presentation, Mr. Jordan
invited TRAC members to comment on his presentation.
Several members were concerned about EPA continuing to make decisions
on pesticides before the science policies are finalized. One member
commented on the amount of progress made by EPA, but she cautioned that
there were still some outstanding science policies that could have some
substantial ramifications on the decision making process. As an example,
she referenced the recent deliberations of the World Health Organization
(WHO) on chlorpyrifos in which they applied a different science policy to
determine risk using the same information that EPA has. This approach
yielded substantially different results in their calculations for chronic
and acute risk. Another individual observed that, while the 19 science
policy papers might be finalized by the middle of 2000, there is not
another statutory deadline until 2002. He questioned the need to rush to
judgment on additional products when some of the science policies could
change between now and when they are finalized. He advised EPA to suspend
decisions such as AZM and MP until the science policies are finalized.
Mr. Guzy responded that EPA was aware they are working on refining
science policies while at the same time making decisions on individual
chemicals. He commented that their interpretation of the congressional
intent when FQPA was enacted was for EPA to manage their schedule in a
reasonable and rational way and not wait until the established deadlines
to complete the reassessments required. He stated that, as part of
responsible management, EPA was also responsible for addressing the most
risky pesticides first. In this regard, he felt that EPA could not stop
the process, but would proceed using the existing science policies and
adapt when and if the policies change. Using the example of the recent
decisions on AZM and MP, the participant did not agree with the EPA
approach because the determination of the safety of chemicals at this time
could change when the policies are finalized, thus causing confusion in
the marketplace. He stated that, in a channel of trade situation, the
registrant will not go back and reproduce the product nor will the farmer
use a product that has been determined to be unsafe. He asked EPA not to
rush to judgement on additional products and take the chance of scaring
the public unnecessarily. Jim Aidala, Associate Assistant Administrator,
OPPTS/EPA commented that no one wants to see EPA stop its work on
pesticides. He observed that if they had, they would not have approved 100
new active ingredients since FQPA. Mr. Aidala reiterated that as EPA
approaches each decision, they evaluate which science policy applies and
how a potential change in the policy might impact the decision so they can
plan appropriately. As an example, he explained that, for MP and AZM they
considered whether a change from 99.9 to a lower percentile could
substantively alter the decision. For MP they determined there would be no
measurable impact, whereas for AZM the impact could be significant, so
they looked at different mitigation measures as a result of that analysis.
A third individual commented that, while he did not feel comfortable
with EPA continuing to make decisions in the absence of final science
policies, he understood that they had to move forward. He expressed
concern about the way the August decisions on AZM and MP were made, and
commented that he and others lost confidence in the progress made over the
past year. He viewed the fact that decisions continue to be made without
finalized science policies as the most compelling argument for continuing
organized stakeholder involvement in the process.
Other TRAC members commented on the drinking water policies. One
individual felt there was a need for more transparency regarding the
drinking water policy papers. She commented that review by the Scientific
Advisory Panel (SAP) was not a substitute for public comment. The
individual was particularly concerned about the fact that risk from
drinking water was recognized as a concern in each of the technical
briefings based on EPA modeling which in turn is based on science policies
that have not yet received comments from the public. Mr. Jordan explained
that when EPA issued Paper number eight, entitled Dietary Drinking
Water Exposure Estimates, they identified two improvements to the
model, index reservoirs and percent crop treated, which they felt would
make the modeling results more realistic. He stated that the comments from
the SAP and the public at that meeting supported these changes. Mr. Jordan
commented that EPA decided to implement the changes based on these
comments, and address the changes in next two papers on drinking water, at
which point the public will have the opportunity to comment. He clarified
that the papers are Paper number 25 on quantitative uses of concern for
drinking water, and Paper number 26 on the kinds of information that
reflects the impact of water treatment on pesticide residue levels
consumed by humans in drinking water. In response to another question of
clarification, Mr. Jordan explained that EPA was developing a tiered
assessment scheme for drinking water that was similar to the dietary
assessment.
The individual also felt that the approach EPA was using to assess
drinking water was "backwards" and she wanted to know why. Keith
Pitts, Special Assistant to the Deputy Secretary, USDA, responded that the
Pesticide Data Program (PDP) residue monitoring program for water would
also be used in the future. He noted that the PDP data and or industry
data might be used for additional information when a chemical is
identified through modeling as a persistent problem. He also noted that no
regulatory decision has been made on drinking water and decisions are
currently made by looking primarily at food uses. Mr. Guzy added that the
Agency recognizes the evolving nature of the work on drinking water which
is why decisions like the one made on August on AZM and MP were tailored
to look primarily at dietary risk rather than relying on the areas of less
certainty. As a final comment, the individual cautioned against EPA
singling out one active ingredient in its study and that it is important
to factor into consideration patterns of pesticide use, geography and
environmental characteristics.
One individual asked for clarification on the stakeholder process that
will be used to address future similar issues associated with new product
registration and reregistration, such as occupational health and safety
and the new cancer guidelines. As a specific example of how the FQPA model
worked, he referenced the paper on common mechanism of toxicity in which
there was a description of the Agency's thinking on the comments received
and how the policies were changed as a result. The individual wanted to
know if EPA was considering a similar approach to address future issues.
Mr. Jordan responded affirmatively.
Another member raised the concern that EPA had not yet addressed the
cancer policy through a transparent process. He felt the issue was not
only what the general policy was, but also how to decide whether a product
should be regulated with a threshold or non-threshold mechanism. He noted
that the potential impact on the risk cup would not be linear when
considering the regulating mechanism. The member felt that the same
standard of transparency applied to other science policy issues should
also be applied to the cancer and other policies, before making too many
additional decisions on products. Mr. Aidala responded that tomorrow's
discussion on post-TRAC activities would begin to address the concern
about how stakeholders would be involved in decisions on future policies.
In response to the question on threshold and non-threshold cancer
assessment, Mr. Aidala explained that the Science Advisory Board (SAB)
which is also a public forum is currently considering this issue. As to
how the process on the cancer policy applies to pesticide decisions, Mr.
Aidala recognized that would be a follow-up issue to TRAC. In addition, he
acknowledged that the application of the different regulatory mechanisms
of threshold and non-threshold can make a substantial difference in the
risk assessment and that is one of the reasons EPA is also anxious to hear
the results of the SAB evaluation of the cancer policy. The member
elaborated on what he saw as a potential connection with FQPA. In FQPA,
when addressing cumulative risk when there is a common mechanism, it is
necessary to consider all of the mechanisms. He encouraged EPA to address
this connection soon. Mr. Aidala commented that EPA is well aware of the
complexity of this issue and explained that the statute was written with
the nomenclature of threshold and non-threshold with this complexity in
mind. He suggested that the discussion on cumulative risk might illuminate
this discussion. As an example of how this concern might influence the
common mechanism, another member referenced the mid-Atlantic Apple review
in which the to-do lists under the chemical scenarios is dependent on
getting chemicals through the pipeline that are either new uses of an
existing active ingredient or a new active ingredient. He commented that
judgements regarding many of those chemicals could be influenced by the
cancer policy. In response to this concern, Mr. Guzy observed the
importance of these points and agreed that it was difficult to wait for
clarification on the cancer policy. However, at the same time, he stated
that it was also important for EPA to ensure that the right scientific and
public processes are used and that process takes time.
Following these comments, Dr. Ehrmann turned to Ms. Stasikowski for her
presentation on cumulative risk. She began with an overview of EPA's
progress on developing a cumulative risk assessment methodology since the
passage of FQPA. Ms. Stasikowski explained that EPA solicited input from
stakeholders, workshops, and other agencies to complete the first phase of
work that was reviewed by the SAP. She explained that in their discussions
with the SAP, they considered the selection of chemicals for cumulative
risk assessment, selection of key toxicity points that would trigger
cumulative risk assessment, risk estimation methods, and how to apply the
uncertainty factor. After summarizing some of the key points of the
methodology in an example, Ms. Stasikowski summarized that in a cumulative
risk assessment, chemicals in a group are compared against the same
endpoint. She stated that the uncertainty factors and safety factors would
be applied to the entire group as appropriate. Ms. Stasikowski clarified
that uncertainty and safety factors from individual chemical risk
assessments will not be used in the cumulative risk assessment. She stated
that the SAP review was supportive of these approaches and EPA expects to
submit information on exposure assessment, risk characterization, and a
case study to the SAP for their review in December 1999. She stated that
the guidance would be available for public review in the spring of 2000.
After Ms. Stasikowski's presentation, Dr. Ehrmann invited members to
comment and ask questions of clarification. One individual asked for an
example of how the uncertainty and safety factors would be applied to a
group of chemicals. Ms. Stasikowski explained by comparing individual
versus a cumulative risk. She used the example of chemical A which causes
eye lesions where they have applied an uncertainty factor for
inter-species of 10 and an intra-species factor of 10, yielding a total
factor of 100. She noted that the same inter- and intra-species factors
apply for chemical B, however the red blood cell cholinesterase never
reached a No Observed Effect Level (NOEL) and an additional uncertainty
factor of three was applied. In the case of chemical B, she noted that the
total uncertainty factor was 300. For the cumulative risk assessment, Ms.
Stasikowski explained that it might not make sense to apply the additional
uncertainty factor of three because the NOEL was not reached, consequently
the uncertainty factor might be 100 with a sufficient database. The member
stated that this policy issue should be addressed in more detail and he
suggested that TRAC would not be complete until this significant science
policy is addressed.
Another individual asked for comments on the development of the
exposure side of the equation and whether there will be a different kind
of demand for exposure data, other than the chemical by chemical and
aggregate data, to complete the entire analysis. Ms. Stasikowski
acknowledged that these are complex issues and explained that EPA will be
presenting exposure assessment issues to the SAP in December and it was
premature for her to discuss them in any detail. Mr. Aidala agreed that
addressing this issue would be difficult and he reassured the member that
the process would be open to peer review. The member added that, with more
detailed residue data and exposure projections, it would be possible to
show instances where simultaneous exposures were not occurring. In
addition, he felt that the approach to collecting exposure data might have
to change in order to address other factors such as the use of different
chemicals on different coasts and the unlikely chance of commingling those
kinds of food supplies to represent a potential common mechanism of
exposure. He posed the question of whether EPA should be thinking about
how to factor these kinds of issues into the current efforts.
One member requested additional clarification on feedback from the SAP
on the common mechanism for OPs. He recalled that the International Life
Sciences Institute (ILSI) determined that there was not sufficient
evidence to say that they did not have a common mechanism, but that a
clear affirmative statement was not made by ILSI. Ms. Stasikowski
responded that the comments from the SAP were supportive of EPA's and
ILSI's conclusion that OPs should be viewed as a common mechanism group.
Mr. Guzy followed up by saying that EPA could pull the language from both
ILSI and SAP to confirm this. He commented that it was important to note
that the Agency concluded that based on the ILSI and SAP findings, the OPs
share a common mechanism.
A participant observed that the September SAP report recommended
grouping OPs together in addition to grouping the class of OPs with some
pesticides in the carbamate class. Based on this, he asked if EPA expected
that other classes of pesticides would be grouped together. Stephen
Johnson, Acting Deputy Assistant Administrator, OPPTS, EPA, responded
that, as EPA continues down the tolerance reassessment road, they
recognize that there will be groups of chemicals, like the OPs and
carbamates, for which they will be seeking public input and determining
whether there is a common mechanism and if there is any crossover. He
noted that EPA is aware of some of the related work being performed by
industry on synthetic pyrethroids that indicates that a common mechanism
is not shared among all synthetic pyrethroids. At the same time, he
cautioned that this is early information that has not been reviewed by
EPA. Another individual asked for clarification on what was meant by the
term "crossover." Mr. Johnson explained that an example of what
he meant by crossover was the similarities between the OPs and the
carbamates. He stated that, based on his limited understanding of
toxicology, he was not aware of other examples of crossover at this time.
Human Studies
Marcia Mulkey, Director, OPP/EPA, provided the group with a brief
update on human studies. She stated that EPA has never required the use of
human toxicity test subjects to evaluate the toxicity of pesticides. In
addition, she recalled that last summer it became clear that a number of
pesticide companies were conducting these kinds of studies. At that point,
she noted that EPA announced an interim approach to its consideration of
these studies to explore the way EPA would handle them while at the same
time consulting with key experts in science ethics to inform a longer-term
approach. Ms. Mulkey further clarified that the Agency announced last
summer that it would not base any final regulatory action on these studies
in the absence of a policy approach that would enable a full evaluation of
the ethical acceptability of the study. At the same time, Ms. Mulkey
indicated that the Agency convened a joint panel of the SAB and the FIFRA
SAP, including regular members and invited members who were eminent
science ethicists, for a two-day meeting in December to discuss these
issues. She explained that, in its preparation of a report on the meeting,
the group determined that they needed additional discussion to prepare a
report on these difficult issues. Ms. Mulkey stated that EPA agreed to an
additional meeting on November 30, 1999. In the meantime, Ms. Mulkey
explained that EPA is proceeding with their interim approach and they are
eagerly awaiting the final report on this issue from the SAB and SAP.
Following her presentation, a member asked Ms Mulkey to explain what
she saw as an inconsistency in timing and approach to the use of human
testing. She referenced guidelines on neurotoxicity testing that were
finalized on May 14, 1998, section 3.1.1.4, Human Laboratory Exposure
Studies, which read, "neurotoxicity assessment has an advantage
not afforded to the evaluation of other toxic endpoints, such as cancer or
reproductive toxicity, and that the effects of some chemicals are short in
duration and reversible. This makes it ethically possible to perform human
laboratory exposure studies and obtain data relevant to the risk
assessment process." Alternatively, she noted that a month later, EPA
made a statement suggesting that no human tests would be accepted because
OPs are neurotoxins. To her, this was confusing and inconsistent. Ms.
Mulkey cautioned that it was important to clarify whether the studies
referenced in the guidelines were human exposure studies, which have not
been the subject of such intense focus with regard to ethical issues. The
member responded that the referenced guidelines were for toxic endpoints.
Ms. Mulkey reiterated that there is concern that a number of these studies
are occurring and it is time to look carefully at the ethics associated
with the conduct of these studies. Mr. Aidala added that this was raised
as a TRAC issue and it remains an unfinished science issue. While it would
be preferable to have addressed the issue conclusively, EPA is now in the
process of resolving it. The member remained confused about whether the
guideline was voided or not. In response to her concern, Mr. Aidala
explained his understanding that the key concern to OPPTS was oral dosing,
however he could not represent what other programs in the Agency were
concerned about in their evaluation of the issue.
In response to Ms. Mulkey's explanation of why EPA announced an interim
approach to considering human testing, one member asked EPA to clarify the
source of its concern about human studies. She observed that human testing
performed prior to FQPA formed the basis for selecting endpoints and
provided EPA with reliable and available data about how a chemical reacts
in a human. She wanted to know if EPA now considered these tests to be
unreliable or whether they considered the tests to be unethical. Ms.
Mulkey explained that, until EPA has a policy to help it sort through
whether to rely on the studies and how for ethics purposes, EPA thinks it
is appropriate not to rely on the historic human studies for any final
regulatory action. She added that they think it is appropriate, aside from
ethics, to evaluate how valuable those studies might be to understanding
other scientific principles. She also noted that, on closer evaluation of
the studies, EPA determined that some of them are not suitable for
continued use and some do not contain conclusive information. Ms. Mulkey
closed her comments with the observation that EPA has also determined that
some of the studies, on which they have based reference doses, are out of
date and better scientific data are available. Based on Ms. Mulkey's
comments, the participant inquired whether this meant that EPA would
approach each circumstance separately. Ms. Mulkey responded that it would
depend on the content of the final policy. The member asked if this
discussion also pertained to studies for worker exposure. In response, Ms.
Mulkey explained that although there are ethical issues regarding studies
conducted to understand worker exposure, they do not present the same kind
of challenging dilemmas that the science panels are struggling with. She
stated that EPA continues to evaluate those and accept or reject them on a
case-by-case basis.
Another member reminded EPA that the decisions it makes on science
policies like 99.9 percent could put the U.S. grower at a competitive
disadvantage, particularly with foreign growers who are not held to such
strict standards. As an example, he referenced the earlier comments on the
consequence of applying the guidelines of the WHO, not the federal
government, on chlorpyrifos. The member also referenced the science policy
on the level of detection as an additional disadvantage to the domestic
grower because foreign growers are not held to the same standard. He
stated that by the time the foreign fruit reaches the U.S., the U.S. Food
and Drug Administration (FDA) is unable to detect residual pesticides and
the fruit is marketable. He urged EPA to find a way to address the ethics
problems regarding human testing in the same manner as done by the rest of
the world.
One member was concerned about the use of the phrase "final
determination" in the interim policy on human testing and asked if
that meant based on the preponderance of the data? Ms. Mulkey explained
this referred to taking a final action with a clear understanding of all
of the issues.
A participant commented on the data call-in for neurotoxicity studies.
She observed that there are some cases where OPs have been further along
in the process at which point the Registrant has received documentation
from EPA indicating that based on the preponderance of the data, there is
no need for a developmental neurotoxicity study. She asked if this was a
firm determination. Ms. Mulkey responded affirmatively.
Tolerance Reassessment Process
Jack Housenger, Associate Director, Special Review & Reregistration
Division, OPP, provided the TRAC with a summary of the tolerance
reassessment process. A summary sheet of his presentation is contained in
Docket # OPP00537. Mr. Housenger reminded TRAC members that the FQPA
establishes time frames for EPA to complete reassessing all of the
tolerances that were on the books as of August 3, 1996, one third of them
every three years until August 3, 2006. He explained that EPA grouped the
pesticides in accordance with FQPA and group one contains the largest
number of tolerances, including those pesticides that are seen to pose the
greatest risks. Mr. Housenger noted that, as of August 1999, EPA met their
goal for completing the first round of reassessments. Out of the total
number of tolerances, 9,721, EPA reassessed and released 3,290, greater
than one third of the total. Mr. Housenger observed that most of the
pesticides reassessed were from group one, and there are 3,369 pesticide
tolerances remaining in group one to be reassessed. Mr. Housenger
concluded his remarks by stating that EPA made additional progress in the
reassessments since August and as of mid-October had completed over 35
percent of the reassessments.
Following Mr. Housenger's summary, Dr. Ehrmann invited comments from
TRAC members. One individual took the opportunity to express his
disappointment regarding EPA's decisions on AZM and MP in August 1999. He
felt that, regardless of the progress made on reassessments, the decisions
represented a step backward in the process because they appeared to be
made for political reasons rather than being based on science. The member
commented that those decisions hurt EPA's credibility and encouraged them
to be more sensitive to the agricultural community by not repeating the
same mistake in the future. Dr. Ehrmann explained that there would be
additional discussion on this topic during the update on OPs.
Another member noted that FQPA's Section 408(Q), Publication of
Schedule, required an initial Federal Register Notice in not less than 12
months. However, he observed that the schedule was changed more than once
since the posting and inquired whether the schedule could be clearer in
the future. Ms. Mulkey responded that while some of the pesticides
reassessed in the first group were not on the first list, the posted list
of priorities is still valid. She also stated that EPA would check this
and make efforts not to post misleading information.
One individual asked for information on what was done with the
tolerances that were completed. Mr. Housenger responded that 1,498 were
revoked and the tolerances that have been reassessed with REDs are as
follows: 143 need to be raised, 133 need to be lowered, 584 remain the
same, 93 need to be revoked, and 46 need to be determined. The individual
also asked for clarification on the label validation process because
inappropriately labeled material creates problems in the market place. Mr.
Housenger explained that after labels are modified to the technical
registration, they ask the Registrant to communicate the change to the
customers. EPA then follows up and asks for voluntary cancellations if
appropriate. The member commented that this process needs to be clarified
because, based on his experience, the communication is not always
happening effectively. He stated that it is unclear whose responsibility
this is. In response to this concern, Mr. Johnson commented that there are
two aspects to think about: one is to make sure the Federal licensing
process is followed and makes its way through the channels of trade, and
the second is label enforcement to make sure the labels are in full
compliance with the action. As a point of clarification, one individual
commented that it falls to the responsibility of the regulating state to
make sure that the labels are changed. At the same time, he observed that
states are generally not included in the decision making process and are
left to react to the decisions. He noted that label changes take time to
implement, as evidenced by products like Paris Green remaining on the
shelves in some locations, and create a lot of work at the state level
where multi-year registrations may be in place. To address a label change
in this circumstance, the state makes the company reregister the product
and this requires time and creates paper work.
In light of the limitations of the studies on neurotoxicity and
developmental effects, one member asked how many reassessments involved
applying the 10-X children's uncertainty factor. Ms. Mulkey responded that
EPA will provide those data but she did not have the details to present at
the meeting. In addition, she noted that there was a major science paper
on how EPA applies the FQPA safety factor analysis that was released in
July 1999. Ms. Mulkey also stated that there were multiple presentations
to the SAP on this subject and a description of how EPA applied the safety
factor in the risk assessments for each of the OPs. As an addendum,
another member referenced a recent comprehensive study by organizations
representing the international community to evaluate whether the current
methods for setting maximum residue limits are adequate for the protection
of developing organisms. She stated that the conclusion of the study was
that there is currently no basis for changing the current approach to
addressing the susceptibility of developing mammals as compared to that of
adult organisms in the toxicological evaluation of pesticides.
Worker Risk Assessment
Dr. Stasikowski initiated the presentation on the expanded public
participation process in occupational risk assessment. She referenced
Staff Paper # 43, Occupational Risk Assessment, for
the presentation and explained that the purpose of this presentation was
to try and respond to a request from the TRAC at the last meeting for
additional information on occupational risk assessments and more public
participation earlier in the process. She summarized some of the related
activities that took place over the summer, including Land Grant
University (LGU) review of the risk assessments and an EPA briefing on the
methodology at the July Pesticide Program Dialogue Committee (PPDC)
meeting. Therese Murtagh, Office of Pest Management, USDA, added that, in
the course of their review of OP risk assessments and occupational risk
assessments, the LGUs concluded that they would better serve EPA as
contributors to the assessments. They also requested additional
information on the data required in a risk assessment and the Pesticide
Handlers Exposure Database (PHED) and on a process that could facilitate
their earlier involvement. To respond to these requests, Ms. Murtagh
explained that EPA initiated a series of meetings with different
representatives from the LGU system, the most recent of which took place
in Louisiana in September 1999. Through the meetings, Dr. Stasikowski
noted EPA was able to clarify the risk assessment process and answer a
number of questions posed by the LGUs. Ms. Murtagh commented that EPA was
well on their way to addressing the LGU's request for more information on
the occupational risk assessment process, but they need to set up a
working process for the involvement of the LGUs as contributors to the
process. She noted that, later in the meeting during the discussion on a
revised public participation process, USDA hoped to add an earlier
opportunity for involvement by LGUs. In addition, Ms. Murtagh stated that
there are a number of upcoming meetings in the spring during which
occupational risk assessments will be discussed, including a multi-day
workshop for LGUs coordinated by Larry Olsen, Michigan State University,
as an expansion of the Louisiana meeting. Dr. Stasikowski summarized the
presentation by emphasizing that the Louisiana meeting was open to the
public, as will be future meetings in the spring. She also stated that
USDA has joined industry and the EPA task force for further development of
the PHED.
A member asked for clarification on the regions represented by the LGUs
and whether different, less traditional agricultural practices were
represented. Ms. Murtagh responded that, at the Louisiana meeting,
representatives from all USDA regions were represented.
Another member supported EPA in its efforts to expand the worker risk
scenarios because they are complex. As an example of the potential
benefits of this effort, she referenced what she thought were telling
comments from the LGU on Bensulide and its agricultural uses. She also
requested clarification from EPA on whether it is evaluating probabilistic
risk assessments for worker exposure scenarios and whether EPA is
accepting this type of risk assessment from industry. Dr. Stasikowski
responded that, as EPA collects more information from the industry task
force they hope to move toward probabilistic risk assessments. She also
stated that EPA is accepting probabilistic risk assessments from industry
and that they hope to see more of them.
One individual clarified that worker risk protection was addressed in
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), not FQPA,
and that FIFRA also requires a risk benefit analysis. He asked EPA to
clarify how it plans to address risk benefit analysis in this context. Ms.
Mulkey responded that in the situation where there are risks posed to
workers, it is necessary to consider whether the risks are unreasonable
adverse effects when the benefits are taken into account. For example, she
noted that risk benefit was taken into account when evaluating whether to
take risk management measures. She stated that the same is true when
evaluating ecological adverse effects. Mr. Aidala also clarified that FQPA
was a set of amendments to FIFRA and the Federal Food, Drug, and Cosmetic
Act (FFDCA) and the amendments to FIFRA did not change the benefit
considerations for worker risk.
Another member asked if in the case where a product is regulated for a
non-threshold effect from the dietary standpoint, was there a bright line
for handling the safety assessment for workers on the same product? Ms.
Mulkey explained that there was not a bright line for handling the general
public safety; however, she commented that there is a point at which the
benefits analysis comes into play.
One individual took the opportunity to provide some perspective on
working conditions in the field. Based on his experience, working
conditions in pesticide production are safe and there have been no
toxicity incidents in his operations for the past three or four years. In
addition, he observed that there have been no incidents resulting from the
application of pesticides since 1984. He stated that as long as people
follow the rules of safety there is no problem. He cautioned against
developing too many regulations because of the potential unnecessary
burden on the industry and agriculture. Mr. Aidala explained the logic of
connecting worker safety and food quality. He noted that, while addressing
aspects of FQPA, the discussions would also logically incorporate the
related FIFRA concerns of reregistration requirements. Mr. Aidala added
that it was important to have a method to make the connection between what
is observed in the field and what is understood in other arenas.
Status Report on Organophosphate (OP) Pesticides
Lois Rossi, Director, Special Review & Reregistration Division,
OPP/EPA presented an overview of the Agency's review of OPs. Ms Rossi
stated that the status report reflects a great deal of work by the Agency,
the Department, and stakeholders present and those not at the meeting. She
acknowledged that there was a lot of work to be done, but she hoped TRAC
members would also reflect on the accomplishments to date. Ms. Rossi
explained that she planned to present an update on the schedule for review
of the individual OPs, technical briefings and stakeholder meetings, and
highlights of decisions regarding several Ops, including MP and AZM.
OP Schedule Update
For this part of her presentation, Ms. Rossi referenced the handout
entitled, Status of OPs in the Pilot Public Participation Process.
She noted that the Agency has released a large number of preliminary risk
assessments that are now in the Docket, including 35 OPs with four OPs to
go. She reviewed the timing of release and the number of preliminary risk
assessments released since the process started in August of 1998. Ms.
Rossi also summarized the number of OPs that are in each phase of the
review process. In addition, Ms. Rossi explained the current activities on
the OPs and how EPA is refining the risk assessments. She noted that EPA
has worked closely with USDA over the past year to ensure that appropriate
refinements were made to the risk assessments that also play a role in
risk management. First, she stated that composite PDP data are used to
estimate single servings in probabilistic risk assessments and the best
data are used in the assessments. She explained that they are determining
risk contributors or drivers and the underlying assumptions for the
drivers. Ms. Rossi commented that for occupational risks they have
received and used a lot of data from the Agricultural Reentry Call-in Task
Force and they have been working to refine the risk assessments using the
best data and assessment tools available.
Ms. Rossi briefly summarized the status of the 39 OPs, four of which
are in Phase 1, four are in Phase 2, and three are in Phase 3. She stated
that 12 chemicals are in Phase 4 and are next in line to have refined risk
assessments released for public comment. Ms. Rossi noted technical
briefings would take place over the next few months for Acephate,
Amidophos, Dimethoate, Methidathion, and Oxydemothon. She noted that there
are eight chemicals in Phase 5 and eight in Phase 6. To date, Ms. Rossi
explained that EPA has released 16 revised, refined risk assessments for
chemicals that are in Phase 5 and 6. She clarified that the same day they
release the revised risk assessments to the public Docket and the
Internet, EPA opened Phase 5 which is a 60 day public participation
period. Ms. Rossi clarified that the 60-day period is the opportunity to
submit risk management ideas and to meet with the Agency to discuss
assessment data, methodology and mitigation proposals.
Technical Briefings and Stakeholder Meetings
Ms. Rossi commented that EPA has learned a lot from the technical
briefing and the stakeholder meetings. Staff Paper # 45, Status
of OP Technical Briefings, provides additional details on the
presentation. She recalled that the pilot process was modified to include
a technical briefing to provide an additional opportunity for stakeholders
to hear a brief presentation on what went into the risk assessment and to
meet with and ask questions of the Agency. She explained that EPA
conducted the technical briefings with input from USDA and they are
scheduled at the end of Phase 4 after the revised risk assessment is
completed. Ms. Rossi stated that eight technical briefings have occurred
and those in attendance included representatives from industry, commodity
associations and growers, and other non-governmental organizations. She
commented that in preparation for each of the technical briefings the
review teams worked closely together and with management to produce a
better quality risk assessment which was presented to the public in
understandable terms. Ms. Rossi stated that the technical briefings have
been a successful internal process for OPP review teams and the management
team and have been beneficial to the public and the Agency in other ways.
She noted that the collective wisdom produced as a result of the
interactions has helped to ensure sound decisions. In addition, Ms. Rossi
indicated that the Agency is committed to the public participation process
and will continue to encourage it by providing notice of the technical
briefings and maintaining good communications with the stakeholder
community. As part of what they have learned from the process so far, Ms.
Rossi explained that EPA is planning to hold the next technical briefing
outside of Washington, D.C. in California where two of the chemicals that
will be discussed are mostly used. She reviewed the upcoming schedule for
technical briefings and explained that the Agency decided against formal
technical briefings for several chemicals because of their limited use
patterns. As an alternative for these chemicals, Ms. Rossi indicated that
EPA staff is available to meet separately to discuss questions and
concerns.
Specific OP Highlights
Ms. Rossi provided the group with some highlights on decisions on OPs
that are close to closure, Bensulide, Profenofos, and Cadusafos. She noted
that for all of these chemicals, EPA has been working closely with the
registrant and the user communities and all of these pesticides are in
reregistration so the work has involved REDs and a discussion of risk
management strategies on the non-dietary concerns. Ms. Rossi stated that
for Bensulide and Profenofos the issues have largely been non-dietary. For
Bensulide, EPA has worked with the Golf Course Superintendent Association
to address turf use issues, and for Profenofos, which is used on cotton,
they have worked closely with the cotton growers on mitigation measures.
For Bensulide and Profenofos, EPA is producing REDs that will stipulate
that the tolerances will not be reassessed until a cumulative risk
assessment is done on the OPs. She indicated that for Cadusafos the
primary concern is an import tolerance on bananas.
Ms. Rossi also referenced an additional OP used in greenhouses for
ornaments, Sulfotep, which has been undergoing reregistration for years.
She stated that the outcome of the reregistration process was to declare
it ineligible. However, she noted that because of its importance to the
industry, EPA has agreed to a five-year phase out plan. Finally, she
commented on the three OPs used for public health concerns, Fenthion,
Naled, and Temephos. She indicated that there was a successful preliminary
stakeholder meeting on these chemicals and EPA plans to discuss risk
mitigation and management plans soon.
Status of Implementation Agreements for Methyl Parathion and
Azinphos-Methyl
Following her summary of OP highlights, Ms. Rossi provided a status of
the implementation agreements for MP and AZM. As background, Ms. Rossi
stated that both of the chemicals have food uses and tolerances that are
required to be released under FQPA and they are OPs in the pilot process
and in the reregistration program. She noted that the review of AZM began
prior to the passage of FQPA and a preliminary risk assessment was
released in August 1998, as one of the first nine released for public
comment in the pilot process. AZM went through Phases 1, 2, and 3, and in
the preliminary risk assessment dietary concerns were raised. Between
October 1998 and May 1999, the Agency, in consultation with USDA, revised
the human health risk assessment and PDP data were integrated into the
process. Ms. Rossi stated that the refined human health assessment
indicated that the chemical would not meet the FQPA safety standard. She
noted that a technical briefing on AZM was held on May 19, 1999 and Phase
5 was initiated involving public participation with an additional focus on
risk management strategy. Ms. Rossi commented that Phase 5 was completed
on July 19, 1999, at which time the fate and ecological effects risk
assessment was still lagging behind. Then Phase 4 began and discussions
with USDA and stakeholders on risk mitigation commenced, drawing from
prior discussions in Phase 5. Ms. Rossi summarized that based on all that
was learned in Phases 1 - 5, it was determined that a modified use pattern
with supporting data would probably be the appropriate risk management
decision for AZM. Based on this conclusion, EPA initiated discussions with
the registrants. Through these discussions, she explained that the
registrant agreed to reduce application rates to pome fruits, cancel some
uses on cotton, sugar cane and ornamentals. Ms. Rossi stated that EPA
believes the use modifications and cancellations resulted in reduced risk
to workers as well as to the ecology, but they are also following up with
the registrants to better assess the risk. She summarized that the actions
they have taken include approving revised labels for the next growing
season, and impending announcements for the cancellations of sugar cane,
eastern cotton use, shade trees, Christmas trees and a number of
ornamentals. Ms. Rossi stated that as an important part of the agreement,
EPA continues to meet on data to confirm that the modified use patterns
will result in reduced residues.
Ms. Rossi then summarized the status of MP. She explained that MP was
not as far along in the process as AZM and that the preliminary risk
assessment was submitted to the Registrant for error correction in October
1998. Following the error correction, the preliminary risk assessment was
released in December 1998, showing levels of concern. She explained that
between February and early August of 1999, the Agency refined the risk
assessment using the benefits of what was learned in the AZM process. She
stated that the results of the refined risk assessment showed that dietary
risks were orders of magnitude above the levels of concern, no further
refinement was possible using current data, and it was unlikely that the
FQPA safety standard would be met. Ms. Rossi indicated that EPA began to
try and identify potential drivers and mitigation measures in May 1999
with the help of USDA, registrants and growers. She stated that a
technical briefing was held in August 1999 announcing the results of the
risk assessment and incorporating the mitigation measures agree to with
the registrant. She noted that the cancelled uses accounted for
approximately 90 percent of the acute dietary risk to children, roughly 10
percent of the total use of MP. Ms. Rossi commented that EPA believes that
these measures qualitatively have an impact on reducing worker and
ecological risks. She summarized that the status of the agreement on MP is
that old use patterns were cancelled on August 25, 1999 and the new
products with the revised use pattern were approved on October 8, 1999. In
addition, she stated that the agreement calls for additional data to be
submitted, particularly addressing worker risks.
Ms. Rossi summarized the next steps for AZM and MP. She stated that
there is a lot of follow-up activity for both chemicals. For AZM, the
Agency will convene a group to develop a production cap which was an
additional mitigation measure discussed along with the other suggestions
for mitigation. She noted that EPA will continue to follow-up on the
specifics of voluntary cancellations, and they will begin to construct the
REDs for AZM. Ms. Rossi indicated that for MP, EPA is still taking
comments on the refined risk assessment. Ms. Rossi closed her comments
with the statement that there has been a tremendous amount of effort by
everyone to get the 35 OPs to their current state. She noted that the
pilot process for the OPs has been used to carry out the reregistration
process for many of the chemicals, with the exception of four chemicals
that were registered after 1984. Ms. Rossi stated that many of the steps
in the process are characteristic of the standard reregistration
decisions; however, the process has been opened up for stakeholder
involvement and the transparency of decisions has been significantly
increased.
After her remarks, Ms. Rossi invited TRAC members for comments and
questions. One participant commented on the importance of the technical
briefings and asked if there had been a briefing on Terbufos, an important
pesticide for cotton. Ms. Rossi responded that they did not have a
technical briefing on that pesticide because of the limited use pattern,
but she invited the participant to request a stakeholder meeting on
Terbufos as an alternative.
Another participant applauded Lois Rossi and Margaret Rice and their
staff for their performance at the stakeholder briefing in Orlando,
Florida the previous week. He felt the only drawback was the absence of
the Department of Health and Human Services (DHHS) and their apparent lack
of focus on these issues. He inquired about the timing for the technical
briefings on the public health pesticides. Ms. Rossi explained that the
stakeholder meeting last week would substitute for the technical briefings
on those pesticides. The member commented that there was insufficient time
in advance of that meeting for comment on the risk assessment for
Fenthion. Ms. Rossi added that the risk assessment is released at the time
of the stakeholder meeting; consequently, the review occurs after the
meeting. Ms. Mulkey clarified that the stakeholder meeting used the same
process as is used at the technical briefings. Mr. Guzy added that the
Agency appreciated the constructive comments on the stakeholder meeting.
One member complimented Ms. Rossi and her staff and the registrant on
the cooperation shown during the discussions on AZM. As a result of his
experience with AZM, he proposed two improvements in the process. First,
he stated that the time frame for obtaining grower comments was too short
for meaningful comments. He suggested that EPA establish a schedule and
stick to it. Second, he felt it was necessary to clarify the way in which
growers should submit their information for consideration, particularly
for minor crops which may not be a top risk driver. As a follow-on to this
comment, Mr. Aidala took the opportunity to prepare TRAC members for some
of the next morning's discussion. He explained that they hoped during
tomorrow morning's discussion on the pilot process to hear more comments
like these on what did and did not work well in the pilot process to
assist in improving the process. Ms. Rossi added as an example, that EPA
learned the importance of early involvement through their experience with
the pilot process.
An individual suggested that it would be helpful to bring the
stakeholders, registrants and the Agency together to evaluate the AZM and
MP experience and have them reconstruct the process on the basis of the
four principles embodied in the TRAC process to highlight the lessons
learned. He also asked whether the FIFRA 6(F) Voluntary Cancellation
Provision, which requires 180 days before the cancellation takes effect,
was waived in the case of AZM and MP agreements and whether the waiver was
published in the Federal Register. Ms. Rossi explained that the agreement
included a waiver of the comment period and a waiver is not typically
published.
In response to some of these points, Mr. Guzy explained that there were
a number of factors that influenced the Agencys decisions, one of which is
their belief that there had been a lengthy public process involving
substantial public review of the risk assessments of these substances. He
stated in the case of AZM, they adhered to the time frames clearly spelled
out in the process developed by the TRAC. In the case of MP, Mr. Guzy was
certain that EPA adhered to the time frames for developing the refined
risk assessment. In addition, he felt that EPA was consistent with what
they have articulated about significant exceedances of the risk cup, where
the Agency reserves the right to move forward on risk management, when
appropriate. He stated that EPA respected the science process and the
meaningfulness of the public participation in forming the risk assessment
for these chemicals.
Regarding the concern that EPA did not meet their requirements on the
deadline of August 3, 1999 and that they did not address the key priority
chemicals specified in the notice, Mr. Guzy commented that EPA does not
agree with this position. However, he also recognized that there are some
who believe that the requirements are not being respected and that EPA is
moving too slowly. As a further clarification, Mr. Guzy stated that EPA
felt that it made sense to take early action to provide growers with
information as quickly as possible, and to avoid confusion. He asked TRAC
members to judge EPA's actions by the character of those actions. Mr. Guzy
commented that EPA, along with USDA, decided to work closely with the
registrants to achieve agreements, and with growers to understand the
critical uses and viable alternatives to achieve risk reduction. He noted
that EPA's approach was not an "across the board" kind of
approach. Mr. Guzy felt that their agreements would withstand the test of
time because they were carefully made and were based on science, and in
the same spirit and in accordance with the principles developed by the
TRAC process.
Another participant asked the USDA if, in developing the AZM and MP
agreement, they considered economic alternatives for the lost uses and
what the transition strategy is for the lost uses. Allen Jennings, Office
of Pest Management, USDA, explained that USDA suggested some modifications
to address the southern peaches and cotton needs east and west of the
Mississippi, but they generally felt there were available alternatives. He
explained that they discussed the issues with a number of rural
organizations and their state affiliates to refine their ideas about
alternatives. Mr. Jennings added that USDA did not think there would be
major transition concerns. Mr. Aidala added that these were the specific
questions EPA and USDA got as they developed the agreement and they
evaluated each question.
One member commented on Mr. Guzy's characterization of the AZM
experience. She stated that she hoped that the process used to reach an
agreement on AZM is not the intended process because the 48-hour period to
reach a settlement agreement is not reasonable and is not consistent with
the process laid out by the TRAC. Mr. Johnson responded that one of the
issues EPA faces is whether there are other examples similar to AZM where
the pesticide is well studied and has been in the queue for years. He
suggested that, while in a sense 48-hours seems a short period, when you
consider that the pesticide has been in the queue for years, 48-hours may
not seem so unreasonable. In regard to MP, Mr. Johnson commented that EPA
exercised its right to take action outside of the six phases if they felt
there was sufficient risk. In the case of MP, he stated that EPA felt it
was necessary to take action. Also, Mr. Johnson commented that EPA felt
they used a constructive and deliberative process and that addressing 90
percent of the risks with 10 percent of the uses is not invoking a food
scare. In balance, Mr. Johnson observed that most of the OPs have gone
through the pilot process and only two were identified with dietary risk,
AZM and MP. He asked the participants for some feedback on how EPA was
doing with Bensulide, as another example. The participant responded that
the dialogue on Bensulide has been very good, in particular because of
stakeholder involvement. She felt that when there is an opportunity for
stakeholder input in the decision making process, a better decision
results. Another participant echoed the concern about the short time frame
for response, however, he also recognized that there were other time
constraints and pressures contributing to the circumstance. He suggested
that it was important to acknowledge that the process was working more
smoothly now and focus on that. Ms. Mulkey commented on the concern about
the short time frame for the AZM agreement. She clarified that the
dialogue with the registrant was initiated in June 1999 and there was more
like a two-week window of active discussion before the decision was made.
Another individual requested clarification on how and whether the
grower groups were involved in the decision making process for AZM and MP.
Ms. Rossi stated that the growers were involved. For example, in the case
of AZM, the process was initiated through the first meeting with the
registrant and the major commodity group. Following that meeting, Ms.
Rossi noted that USDA took the lead in keeping in contact with the
commodity groups. She stated that EPA has also used its Minor Use Team to
talk with the smaller commodities, particularly with MP. Mr. Jennings
added that the USDA also spoke with and through a number of their LGUs to
smaller commodity groups. At the same time, he acknowledged that the
process was somewhat ad hoc, which he identified as an issue that will be
part of tomorrow's discussion on ways to improve the process.
A participant asked for clarification on when in the process the
growers come to the table and have a voice. Ms. Rossi commented that that
was a good question and one that has been discussed with a number of
commodity groups because it was not clearly mapped out as part of the TRAC
process. She explained that there was no specific place identified in the
six phases of the pilot program for this and that to date their
involvement has been ad hoc. Ms. Rossi suggested that this would be an
issue to address in tomorrow's discussion on ways to improve the process.
Mr. Jennings agreed that it is necessary to do a better job of integrating
grower input. Mr. Pitts added that another part of the process that has
not worked well is that the refined risk assessments are not clearly
linked with mitigation. Consequently, when the LGU's review the risk
assessments, they are not able to correlate them with real world action.
He stated that that is an issue that the USDA would like to raise in
tomorrow's discussion. Mr. Aidala also clarified that the word
"public" refers not only to growers but to all stakeholders, all
of whom have had access to the same material over a period of years and
who may not have provided input on some of these issues in a timely way.
As a baseline for comparison, Mr. Aidala asked Ms. Rossi to compare the
current process to the RED chapters, which EPA has been producing since
1988. He observed that few people asked for information on the risk
assessments until recently. Ms. Rossi commented that the traditional
practice was to share the chapters with the registrant and discuss the
risk management and mitigation proposals with the registrant. Following
these discussions, the RED was announced.
One member was encouraged that EPA was learning from these experiences,
but she cautioned against assuming that EPA represents the growers in the
country and stated that the growers need to be at the table if EPA wants
their buy-in. She stated that the decision making process concerns her
greatly because the consequences affect her livelihood. Another member
responded to Mr. Aidala's comments on the REDs, by stating that the stakes
were different under the RED process because FQPA covers more and the
timing is different. The participant also observed that it is too soon to
know the full impact of the AZM and MP decisions because they are late
season decisions and there were still OP alternatives available. He also
stated that it is hard to evaluate the short and longer term impacts of
these decisions because it depends on what EPA does with new registrations
and whether they fit in with existing Integrated Pest Management (IPM)
systems. Further, he stated that the transition strategy for row crops is
very different for perennials and ornamentals. In this regard, IPM
strategies are very site specific and require a lot of information. He
wanted to know where the information is coming from to help growers make a
transition with a system that is already challenged by the processes we
have put in place.
An individual observed that comments on the preliminary risk
assessments are not always placed in the Docket in a timely way. He stated
that if he knows his comments will not be used or placed on the Docket, he
will not spend the time commenting and would rather reserve his comments
for something that will be used like a refined risk assessment.
A member asked for clarification on the following: 1) Regarding the RED
process and AZM, will the label changes be based on dietary risk? 2) Has
occupational exposure been evaluated and how does that fit into the RED
process? Ms. Rossi explained that most of the label changes correspond to
the rates that were related to dietary risk and the reentry intervals will
change for worker protection. In addition, she clarified that the RED
process involves a comprehensive review of the entire chemical. Everything
is evaluated including dietary, worker, and ecological risk. In response
to a question on occupational exposure, Ms. Rossi added that because the
ecological and fate assessment lagged behind the health effects
assessment, she was uncertain whether the occupational exposure would be
revised.
One individual expressed concern that the discussions at the meeting
did not sufficiently address protection of children. He stated that
children's health should still be the guiding principle for the process.
The individual recalled the description of how children's safety factor
was addressed with regard to AZM and felt that there was not enough detail
on why the safety factor was not applied. He questioned the source of
information on risk, whether it came from the SAP or some other sources,
and how the subsequent results would impact growers, registrants, and
public health. The individual stressed the need for the process to address
the public health aspects consistently. Mr. Johnson thanked the
participant for his comments and stated that both EPA and USDA are
concerned and need to reach out to different constituents for comments and
concerns. He also commented that the principle behind FQPA is public
health and environmental protection - public health in particular, given
the FQPA's particular attention to children. Mr. Johnson stated this
principle guides the actions EPA has taken. As an example, he referenced
the AZM agreement where the risk driver was the sub-population of children
from one to six. Another participant supported the concern about children
and shared his appreciation for the diversity of perspectives remaining at
the table.
Transition Issues
Mr. Jennings provided the group with an overview of the progress on
transition issues. He referenced the USDA document entitled, The
Foundation for a Transition Strategy for Lessening Dependency on
Organophosphate Insecticides in the Mid-Atlantic/Appalachian/Southeastern
Apple Production Region, as an example of the technical basis for the
discussion. Mr. Jennings stated that transition is interpreted differently
by certain individuals to some, it means a specific response to a risk
assessment, and to others a planning document with a long range view
looking at changes in fundamental pest management practices such as moving
towards environmentally friendly, more biologically-based pest management
systems. He noted that a common thread through all of the potential
definitions of transition is the need for a firm technical basis. Mr.
Jennings commented that the information platform or technical basis for
pest management alternatives should be common for a commodity for a
specific region. In this regard, Mr. Jennings observed that pest
management issues are local, consequently the key to a good transition
strategy is knowing the commodity and the region in which it is produced.
Mr. Jennings referenced two similar studies on peaches, one in California
and the other in the southeastern region. He noted that the California
study is complete and they hope it can be expanded and applied to other
stone fruits and many common pests because of common growing conditions.
The peach study in the southeastern region should be available in a few
weeks.
Mr. Jennings also explained that USDA had been meeting with their LGU
cooperators to discuss continuing the effort to work with their state and
local organizations on high priority commodities. They envision involving
crop production experts from the LGU system, the grower community, and
from the Agricultural Research Service (ARS). He described the output from
the studies as varied, including a collection of information about pest
management alternatives and a "to do" list to ensure that
actions are taken. Mr. Jennings clarified that actions may include
inspiring the ARS to change the fundamental direction of research or
emphasize particular research. He summarized his comments with news that
USDA is likely to be funded for two new programs: Crops at Risk; and the
Risk Avoidance Mitigation Program, both of which could further transition
implementation. He then invited participants to comment on the apple study
and on the "to do" list.
Several members complimented USDA on the overview. They felt the
example was helpful as was the "to do" list, and the series of
questions that were posed in the document were instructive. One individual
commented that the questions presented in the document suggest the need
for new products and new uses. She stated that it would be helpful to know
more about the status of some of these alternatives. In addition, she felt
the information about the status of pesticide alternatives for different
pests could be used to help prioritize the next steps in the pest
management plan. For future similar studies, she suggested adding the
perspectives of growers and food processors to the work group. She
recognized the potential for transition strategies to be complex and for
this reason she felt that finding a way to prioritize the key issues in
each region would be key to the success of a transition plan. Another
participant also recognized that much of the work done in this region
could be applicable to other regions. However, she also noted that it
takes time to confirm the success of larger scale applications of
alternatives that were successfully used on test plots. In addition, she
noted that some successful alternatives are labor intensive and may not be
practical for that reason.
An individual requested clarification on what was meant by a
"systems" approach and wondered whether it was appropriate to
consider a systems review as part of a transition strategy. He also stated
that, based on a preliminary review of the alternatives presented in the
document, several of them would not be viable. He suggested that USDA
consider providing some prioritization of the available alternatives as an
additional tool for planning transition. His final question was whether
USDA referred to and utilized the Work Group II discussion on using a set
of criteria as a way to define alternatives. In response, Mr. Jennings
recognized that developing transition plans is and will involve a dynamic
process of testing and shifting pest control measures. He indicated that
the approach used in selecting alternatives would meet the definition of
alternatives considered by Work Group II. Mr. Jennings turned to Wilfred
Burr, Office of Pest Management Policy, the primary author of the paper,
to respond to the question on a systems approach. Mr. Burr explained that
it took approximately a month and a half to produce the apple strategy for
transition. On the systems approach, Mr. Burr commented that the necessary
step of applying small scale orchard research on alternatives to broad
scale application would require a systems approach that would look at the
big picture, including insecticides and herbicides. He also commented that
the work group that developed the paper screened alternatives in part
based on their economic viability. In addition, Mr. Burr noted that the
work group identified a need for education for the growers on the
alternatives and how to use them.
For an additional perspective on a systems approach, a member commented
that systems research found its origin in electrical engineering as a way
to identify the universe of control. He observed that many of the elements
in the agricultural system are dynamic and require monitoring. In the
agricultural system, the individual described starting from the current
practices, identifying the future goals for the system (e.g., reduced use
of OPs, etc.), followed by designing a system to get from the current
state to the future state. He noted that this process would take a lot of
on-site research. The individual also observed that transitioning from a
relatively simple system of spray control to more complex alternatives
will require more information to manage the system. He questioned whether
there was a source for this information and whether there was a system to
disseminate the information.
Another member stressed the need to educate the public on some of the
success stories on transition. She felt that some of this public education
could help people to understand what the farmer is dealing with in the
field. She wanted to know if there were any specific plans for advising
the public in this way.
Another individual commented on the implication in the paper that 60 to
70 percent of the apples are for processing, when in reality a higher
percentage of the apples are fresh. The individual also observed that
transition plans need to look more broadly at alternatives, not just as
potentially controversial OPs and carbamates. At the same time, he
commented that the goal of a transition plan might not be to phase out
OPs, but rather to have OPs regulated based on their risk and to have
those risks mitigated. The participant commented that for apples at this
time there are very few proven alternatives. In the regard, he cautioned
that there might be fewer applicable alternatives in the pipeline than we
think. Mr. Burr agreed that there are regional differences in the
percentage of apples processed and fresh and that regional differences
need to be taken into account in a transition plan. He also acknowledged
that OPs were not enough as a pool of alternatives and that a longer term
perspective on OPs that might be phased out would be appropriate. He
explained that this is why the study was characterized as the
"foundation" for a transition strategy designed to point out
what needs to be done if the OPs are phased out or if the uses are
modified over the next few years.
A member highlighted the fact that OPs are currently critical to the
control of pests at different times in the growth cycle of apples. For
this reason, he stressed the importance of proceeding with caution when
considering an OP phase out, particularly when there are limited or no
alternatives. He felt that this study accentuated some of the pitfalls
agriculture faces and the present and critical need for research on
alternatives.
Another individual expressed concern that organic farming was not
identified as an alternative. He provided examples of successful organic
farming and stated that it should be considered as a viable alternative.
Mr. Burr explained that the work group on the paper considered organic
farming, but felt it was not applicable to the size of orchard considered
in the study. The member noted that organic farming has been used
successfully on substantial orchards. One individual agreed that we should
not lose sight of organic farming as an alternative, and that we should
take a closer look at the circumstances under which it is a viable
alternative and consider it as an alternative in those circumstances.
One member felt that the paper pointed out that the role of USDA in
risk assessments and risk mitigation should be expanded. He felt this
expansion would increase the credibility of the process and that funding
should be made available for the expanded role.
An individual supported the inclusion of resistance management in the
study because it is a critical and real concern. He also asked for
clarification on the audience for the document. Mr. Jennings responded
that the audience for this and similar documents would be the agricultural
research community and those interested in transition. Ms. Murtagh also
stated that they were still trying to answer what resistance management
means to EPA, USDA and the LGUs. The member suggested that the commodity
groups should also be the intended audience. He proposed as a next step
that a commodity group take a study like this and based on it, develop a
business plan for the next five years. Mr. Burr was supportive of this
idea.
A member commented that he hoped that some of the additional research
on transition would also go to studying endpoints because they are a
critical part of the big picture and refining appropriate alternatives.
Mr. Burr responded that some of the items on the "to do" list
point in the direction of endpoint studies.
At the close of the discussion, Mr. Guzy reflected on the work that was
done on the study and some of the comments in this session. He recalled
the comment on the importance of including growers in risk mitigation
decisions and Mr. Johnson's comment about thinking in a rational,
comprehensive way about the future given the likely scenario on the use of
OPs. He also noted that EPA has established a time frame for action to
which they are committed. He stated that, as with AZM, EPA can make
certain assumptions in cooperation with USDA, registrants and growers
about targeted approaches and reasonable phase-outs and transitions.
However, he also saw this as an opportunity and a challenge, as indicated
in the August 2, 1999 announcement by Administrator Browner, for pesticide
manufacturers and growers to propose additional voluntary measures to
reduce risks from other OPs and to shape future actions on OPs and other
pesticides. Mr. Guzy noted that some preliminary ideas about the criteria
for voluntary programs were presented in the August 2 announcement. They
included a focus on the most significant risks associated with children's
foods, eliminating uses or achieving no detectable pesticide residues in
high consumption children's foods, moving toward safer use, use of safer
reduced risk alternative pesticides, and defining an acceptable timeframe
for achieving goals. Mr. Guzy recognized that this should not be done
alone by a voluntary group, but with the support of the government. For
this purpose, he stated that EPA and USDA have discussed an approach to
targeting resources for critical research and extension. In addition, he
commented that EPA is committed to expediting registration of reduced risk
pesticides and promising new chemicals and chemical uses. He noted that
this kind of program was somewhat overlooked in the August 2 announcement
and the Agency is open to others finding common sense transitional
mechanisms, building on the base of knowledge provided in the report that
was just presented.
Mr. Rominger appreciated the positive and helpful comments on the
report and stated that USDA will use the comments to improve future
transition strategies. He added that these comments help USDA to clarify
where they need research and where they need to place more effort. Mr.
Rominger also noted that when additional resources are secured, with the
help of industry and growers, USDA could make a difference in the process.
He thanked USDA staff for their work and commented that they developed a
model that can be built on in the future.
Tolerance Revocations/Channels of Trade
Mr. Housenger described the channel of trade issue and the provision in
FQPA that addresses it. He explained that, after a crop is treated with a
pesticide, detectable residues of the pesticide might result. Mr.
Housenger noted that following harvest, the product goes through points of
distribution, or channels of trade, on its way to sale and consumption. In
the case of fresh food the produce moves through commerce quickly, where
as in other cases, such as with processed food, commodities with
detectable residues could remain in the channels of trade for up to four
years. Mr. Housenger stated that the channels of trade might become an
issue when, through reregistration the use is cancelled, or it is
voluntarily cancelled and tolerance revocations might occur as a result of
FQPA. He noted that where tolerance reassessment results in termination of
the tolerance, a revocation is the means by which the reassessment is
completed.
As background, Mr. Housenger described the provision in FQPA that is
designed to solve the issue with channels of trade in Section 408(5),
otherwise known as the "safe harbor provision." He explained
that the law states that any food that was treated lawfully under FIFRA
prior to the revocation shall not be deemed unsafe as long as the residue
does not exceed the level of tolerance that was in place at the time of
treatment. As a caveat, Mr. Housenger noted that EPA could override this
provision should it determine that the food poses an unreasonable dietary
risk. He added that the Agency is committed to assuring the implementation
of these provisions in a way that addresses the channel of trade issues.
He commented that EPA is working with FDA and USDA on the implementation
of the safe harbor provision, determining what kinds of information the
Agency needs to provide for implementation and ascertaining what special
circumstances may need to be addressed as a result of its implementation.
He explained that EPA has already begun to provide information to FDA on
expected residue levels for commodities for MP, in addition to information
on the length of time fresh and processed commodities remain in the
channels of trade. Mr. Housenger commented that he hoped this kind of
information would assist FDA in developing its strategy for implementing
the safe harbor provision. He then turned to Robert Lake, Director of the
Office of Policy, Planning and Strategic Initiatives, Center for Food
Safety and Applied Nutrition, FDA, for an explanation of how FDA is
addressing these implementation issues.
Mr. Lake recognized this issue as important and difficult. He noted
that one of the difficulties is meeting the desire to assure that lawfully
treated food is allowed to go through the channels of trade to be sold to
consumers and consumed, while at the same time addressing a use that has
been canceled and the tolerance revoked. Mr. Lake described the channels
of trade as a pipeline that is always full, that goes from the farmer's
field to the fork of a consumer. He explained that when a decision on a
pesticide and a commodity is made, it affects some products that are in
the pipeline. Mr. Lake interpreted the congressional intent of the
provision to allow the material in the pipeline to continue to move,
unless there is a finding that was contrary to public health. He stated
that this issue is not new, as tolerances were revoked prior to FQPA, and
now as in the past, FDA recognizes the challenge of discerning between
residues remaining after a period of time in the pipeline that result from
lawful treatment from those that are not. He observed that this point of
discernment could vary depending upon the pesticide and the commodity. In
addition, Mr. Lake noted that there is a tension between wanting the
channels of trade to clear, while at the same time not allowing the
continued use of a pesticide after it is no longer allowed. An additional
tension is between allowing the channels of trade to clear while at the
same time not allowing foreign growers to unfairly take advantage of the
situation. In regard to the challenge with foreign markets, Mr. Lake
explained that while a registration can be canceled in the U.S., it may
still be allowed in other countries. However, he noted that when produce
from foreign markets enters the U.S., it is monitored by FDA and is
subject to meeting the allowable pesticide residues in the U.S. Mr. Lake
commented that this circumstance creates an additional tension between the
domestic grower who can no longer use the pesticide and the foreign
producer who continues to use the pesticide and take advantage of the U.S.
market.
To address some of these challenges, Mr. Lake summarized an approach
for FDA which is based on past practices. He stated that the desire is to
have a policy to effectuate the channels of trade while assuring that
fresh produce goes through the channels of trade before FDA acts on an
enforcement program to look at the residues. In addition, he noted that
the policy should also address the fact that there will be some processed
food that will have a longer shelf life and be in the channels of trade
longer. Mr. Lake clarified that these foods are likely to have detectable
residues below the tolerance longer than fresh foods, but at some point,
the level drops to below detection. In the case of MP, Mr. Lake indicated
that information provided by EPA suggests that the levels of MP in fresh
fruits will decrease to non-detection within a year and FDA feels it is
unlikely that they will detect MP in fresh produce by the next fiscal
year. However, some levels of MP may remain in processed foods for up to
two years. He invited suggestions on how FDA should address the longer
term residue issue for MP. One idea that they have considered is requiring
processors to track the date they process their food. In closing, Mr. Lake
stated that FDA is in the process of developing guidance on this issue and
the draft will be published in the Federal Register for public comment. He
invited TRAC members to comment on his presentation and the future draft
guidance.
Following Mr. Lake's comments, Mr. Jennings added that the Food Safety
Inspection Service (FSIS) provides the enforcement mentioned by Mr. Lake
on poultry, meat and eggs. He envisioned that FSIS would develop a
parallel system to the system ultimately developed by EPA. In addition, he
noted that there might be export issues other than enforcement that might
be key to U.S. tolerances, such as in the Taiwanese Trade Agreement.
One member asked for clarification on how much imported fresh produce
FDA is able to inspect. Mr. Lake stated that they are able to check less
than one percent of the total because the volume has grown substantially
in recent years. In a similar vein, the participant inquired about the
percent of processed imported food that is checked. Mr. Lake stated that
the amount of all imported foods, fresh and processed, might be between
one and two percent. He added that the level of FDA sampling for imported
and domestic foods is at an all time low and is half of what it was at the
beginning of the decade, following a declining trend over the past two
decades. Mr. Lake commented that there has been a long term trend towards
declining resources for monitoring and enforcing pesticide tolerances in
food.
Mr. Aidala inquired whether PDP data includes both domestic and
imported foods. Mr. Jennings responded affirmatively that it is both and
indicated that they report violations to FDA. Mr. Lake commented that this
is useful intelligence, however, by the time the information gets to FDA,
the food is long gone and their ability to track the source of the
information is limited. He noted that the PDP information informs FDA on
the commodity and provides some idea about the source of the food.
An individual found it ironic that in FQPA one of FDA's goals was to
move away from action guidelines in the Section 18 process because those
numbers were not defensible, and the current circumstance is similar
because we are moving away from actual tolerances and essentially
"looking in the other direction." Mr. Lake clarified that, in
this case, the old tolerance number applies as long as the food remains in
the channels of trade. He reiterated that the challenge is determining at
what point it is possible to say that the value seen was or was not in the
channels of trade when the action was taken. In the case of MP, Mr. Lake
explained that FDA would monitor as they always do and if they find a
residue within the old tolerance for MP within the first year, they assume
that the food is legitimately in the channels of trade and was lawfully
treated. However, if the values were above the old tolerance level, FDA
would take action. Similarly, if FDA observed a value below tolerance for
food that had been in the channels of trade for more than a year, they
would assume the value was not lawful. The member asked if states would
adopt a similar strategy. One representative from state government
indicated that their policy would probably be similar. The member also
asked if the example of MP was a worst case scenario that might apply to
the dissipation of many pesticides. Mr. Lake responded that it was not a
worst case scenario and that he understood each case would be addressed
individually. Mr. Aidala clarified that it is not only the dissipation of
the pesticide, but also the dissipation of the food form through the
channels of trade. Mr. Housenger added that residue levels calculated over
three, six, and nine months assumed that the commodity was treated at the
label rate closest to harvest, consequently PDP data indicate the levels
seen in commerce are lower than that.
An individual inquired about the practice for products that are stored
for a longer period of time, such as grains, that may also be mixed in
storage. Mr. Lake commented that this is one of the most difficult
challenges in an implementation plan and asked for suggestions on how to
address this. The individual felt that this circumstance was an example of
a fundamental problem for food processors; that they are guilty until
proven innocent. He felt their only recourse was to refuse to purchase
crops treated with MP. Mr. Lake suggested one way to address this concern
would be to say that for processed food anything that the processor buys
and processes within a certain time frame is presumed to be okay. He
stated that FDA would like input on this approach and how to deal with
foods that have been in the channels of trade for longer periods of time.
Another member felt that this discussion suggested that the policy was
shifting back to practices prior to FQPA. He understood that one of the
initial reasons for FQPA was to appease the World Trade Organization (WTO)
under the Section 18 process that we did not have a tolerance established,
in which case they could not import commodities from other countries. Now,
he observed, there is a time limited tolerance and we are in a
circumstance similar to the one that existed prior to FQPA and are placing
foreign countries at a disadvantage because we are essentially doing away
with tolerances. He commented that the WTO would not be pleased. As a
second concern, the individual questioned EPA's ability to harmonize with
neighbors like Mexico and Canada in view of the recent decisions on AZM
and MP. He felt that it was unreasonable to assume that they will alter
their use of these pesticides. In addition, from the processor's point of
view, many domestic juices are blended with fruit from other countries. He
did not see how revoking someone's tolerance in the U.S. would not have an
impact on growers in the U.S.
One participant commented that the situation is not black and white. He
noted that one pivotal point is that the application of the tolerance
revocation and what triggers the revocation. He noted that there may be
some discretion in its application and this may address some of the
concerns expressed. The participant observed that with MP, there was a
safety finding that foods that have been treated during this growing
season and into the future are safe because of the continued use of MP
after the cancellation decision. He felt this poses a different situation
than when a decision is made that those foods are not safe, there is a
residue problem, and immediate action is required. Regarding the concern
about a "level playing field," the individual noted that the
domestic industry is impacted when the domestic grower cannot sell his
crop, the processor cannot accept the crop, or the customer will not buy a
product because of pesticides. He commented that this circumstance needs
to be evaluated more carefully by a broader audience to determine if
addressing the channels of trade in this way will cause minimal disruption
while at the same time maintaining the safety standard that has been
discussed all along.
Another member commented on foreign trade and the channels of trade. He
stated that he works with two foreign trade partners for fresh and
processed materials that are dependant on U.S. tolerances, and these
partners defer to the U.S. tolerances where there is no Codex MRL or other
applicable tolerance. In this regard, the individual was concerned about
the MP decision because, if cancelled, it will jeopardize the crops that
have been treated with MP and will impact a number of growers and packers
in the U.S. A second concern to this participant was how the decision on
MP would impact those in the frozen concentrate industry. He explained
that, in some cases, the juice concentrate is frozen for a period of four
years, thus creating another channels of trade issue. Mr. Aidala clarified
that the contract for the law of trading partner can be modified to say
that it meets U.S. standards or some other benchmark as opposed to a
tolerance.
One individual provided another example of the complexity of the
channels of trade issue in the citrus market and how growers and the
people who buy the product expect to be at the point of compliance. As an
example, he described the process for fresh citrus juice production at a
plant in Florida. He noted that the packinghouse runs up to 130 truckloads
of fruit per day through the processing facility. Each load of fruit is
segregated prior to USDA certification for juice processing. The
individual noted that the juice is then commingled with the other
truckloads for the day and contained in tanks for up to two years. The
individual wanted to know how to advise people in his industry on how they
can meet the standard that will allow them to meet the safe harbor
provision within these common timeframes. Mr. Lake stated that FDA plans
to develop guidance for public comment later in the fall of 1999; so now
is the time for input on implementation.
Based on the preceding discussion, it was unclear to one participant
whether EPA was suggesting that OPs be taken off the market and he wanted
to make sure that there was discussion on the issue before any such
decision was finalized. Mr. Pitts clarified that that is not the case, and
the confusion may have been the discussion on the apple study where one
scenario which was to assume that OPs will be phased out of use. The
individual was also uncertain whether EPA was suggesting that they
discontinue the tolerance system. Mr. Aidala stated that the goal is to
meet the standard which may or may not result in the elimination of
products. Secondarily, he stated that there would still be a tolerance, or
an enforcement level at the detectable level. Mr. Pitts added that USDA is
trying to engage growers to discuss transition over the next five years
and one of the goals in the risk avoidance and mitigation program is to
solicit proposals from the commodity groups on how to achieve a no detect
or lower residues. The individual cautioned against EPA and USDA pushing
the limits of the agricultural system by eliminating OPs and requiring no
detectable levels, because the agricultural community and the American
public will suffer the consequences.
Public Comment
Adam Sharp, American Farm Bureau Federation - commented on the
importance of preserving the opportunity for public comments on the
drinking water science policy papers numbers 18 and 19. He stated the SAP
meeting does not provide sufficient opportunity for comments because there
are also elements of policy in each of those papers.
THURSDAY, October 21, 1999
Dr. Ehrmann opened the second day of the TRAC meeting with a review of
the agenda for the day. The agenda included two topics suggested on the
first day, data call-in and the PR notice on worker protection. Additional
scheduled topics included the public participation process and post-TRAC
activities, and time for public comment. Dr. Ehrmann then introduced Lois
Rossi for preliminary comments on the data call-in and the PR notice.
Data Call-in and Worker Protection
Data Call-in
Ms. Rossi commented that both the data call-in for neurotoxicity
information and the PR notice on worker protection were announced on
August 2, 1999. Regarding data call-in, Ms. Rossi stated that EPA is
requiring Registrants of pesticides thought to have neurotoxic effects to
conduct acute, sub-chronic and developmental neurotoxicity studies. She
stated that the program to call-in data will apply to approximately 140
pesticides and will be completed in phases over the next several months.
Ms. Rossi noted that on September 10, 1999 EPA issued the first phase of
the data call-in notices which are referenced in the handout entitled, New
Data Will Help Ensure Protection of Children. She stated that EPA
issued the data call-in notices to all the registrants that had
registrations for OPs, including formulators and base manufacturers, and
they are required to respond within 90 days indicating how they plan to
respond to the data requirements. After her remarks, Ms. Rossi invited
questions and comments from TRAC members.
One participant inquired how many laboratories are equipped to test the
required 140 compounds. Ms. Mulkey responded that EPA looked into the
laboratory capacity issue and that is one reason EPA is approaching this
in phases. She stated that to the extent that laboratory capacity is a
limiting factor, registrants could work it out with EPA. The individual
also asked for clarification on the issue of inter-laboratory variability
and protocols for some of the newer behavioral measurements. Ms.
Stasikowski explained that EPA has a work group that is preparing a
consultation process for registrants to come and discuss protocols and
other related issues for these measurements. The participant explained
that a particular concern of hers was the lack of historical control
experience for some of these studies, against which to compare the new
data. Ms. Stasikowski indicated that the work group would also address
issues like that.
Worker Protection
Ms. Rossi referenced the handout entitled, Fact Sheet on PR Notice
Worker Risk Mitigation for Organophosphate Pesticides, for details on
this presentation. She noted that this PR notice is also out for public
comment. Ms. Rossi explained that the notice presents an approach EPA has
been considering for years to level the playing field with across the
board measures on classes of compounds like OPs. She noted that this
approach would encourage, during the risk assessment process, closed
systems and enclosed cabs. Ms. Rossi noted that EPA would ask voluntarily
that registrants do this by the end of the year 2000 to the extent
required by the risk assessment. She stated that the fact sheet presents a
description of the approach for reviewing each OP and making decisions to
manage the worker risks.
There were no comments or questions on this presentation. Dr. Ehrmann
then asked Ms. Rossi to provide an overview of the public participation
process.
Public Participation Process: Next Steps
Ms. Rossi provided the TRAC with a presentation on the public
participation process for tolerance reassessment and the reregistration of
OPs. She noted that EPA and USDA have been using this process since it was
developed by the TRAC last summer. She explained that the results and
statistics on the process were described during the meeting yesterday and
today her presentation would focus on the process. Ms. Rossi stated that
the goal of the process was to increase transparency of EPA's regulatory
processes and to enhance consultation with stakeholders by expanding
public access to EPA's risk assessment and risk management processes.
Through their consideration of the process, Ms. Rossi hoped that the TRAC
members could help take the "pilot" out of the process. In
addition, she noted that EPA and USDA would also like input on whether the
process should be applied beyond tolerance reassessment for OPs and
applied to other pesticides subject to reregistration and tolerance
reassessment. She also stated that she would provide an update on activity
at the end of this fiscal year on pesticides other than OPs. First, Ms.
Rossi planned to share how EPA and USDA believe the process is working and
then, based on that experience, discuss modifications to enhance the
effectiveness and efficiency of the process and produce better products
and make better use of everyone's time.
Ms. Rossi summarized that there are six phases in the process, which
are presented in Staff Paper # 42, Public Participation
Process Options for the Final Process. The phases are: Phase 1,
Registrant "Error Only" Review; Phase 2, EPA Considers
Registrant's Comments; Phase 3, Public Comment on Preliminary Risk
Assessment; Phase 4, EPA Revises Risk Assessments; Phase 5, EPA Solicits
Risk Management Ideas; and Phase 6, EPA Develops Risk Management
Strategies. In her overview, she noted that Phase 4 was modified as
discussed at the April TRAC meeting to include USDA's review of the
revised risk assessment. At that time, she noted, they also added the
technical briefings to share the revised risk assessment with the public
to increase the transparency and to assure public understanding of the
risk assessment.
After describing the phases of the process, Ms. Rossi reviewed some of
their experiences with the process on what was received and what was not:
Phases 1&2 - 31 OPs completed the "Registrant Only" error
review period; most comments were not error-related and did not impact the
release of the preliminary risk assessment; 5 preliminary risk assessments
were modified; 11 OPs received mostly error corrections from registrants,
half of which identified mathematical errors and others included spelling
and grammatical corrections; 20 OPs received non-error comments including
objections to the risk assessments and commitments to submit new studies;
and some of the older preliminary risk assessment received no comments.
Phase 3 - 27 OPs have completed the public comment period on the
preliminary risk assessment; from non registrants comments generally
supporting or opposing aspects of the assessment were received for 18 OPS,
and 9 OPs received submissions of usage information, studies or other
technical information; registrants submitted mostly general comments, five
of which were new studies and studies to confirm or upgrade existing
submitted studies. Ms. Rossi commented that receiving use and usage data
and new studies resulted in rework, consequently it would be helpful to
receive this information earlier in the process.
Phase 5 - comments and ideas on risk management were usually received
by EPA via meetings and conference calls rather than written submissions.
Ms. Rossi then summarized some of the lessons learned in the process
and some of the guiding principles for modifying the process. She stated
that the first lesson was that the earlier the involvement and receipt of
information, the more useful the information was in improving the accuracy
of the risk assessment. Similarly, EPA learned that it is helpful to have
earlier involvement in developing risk management strategies. The second
lesson she noted was that many of the tools that are developed and needed
to refine the risk assessments are now developed and there appears to be
little added value to producing an unrefined risk assessment based on
assumptions of 100 percent crop treated and tolerance residue levels. Ms.
Rossi stated that EPA proposed beginning the public review process with
the refined risk assessment. She observed that there were very few
comments on the preliminary risk assessments and EPA has heard many
stakeholders agree with this revised approach. She stated the third lesson
was that there is a need to have a process that is understood so
stakeholders can plan effectively and know what information is useful to
the agency. She stated that stakeholders need some degree of
predictability in the process and the schedule of chemicals being
reviewed. Ms. Rossi noted that the fourth lesson learned was that a common
understanding of the risk assessment was needed before stakeholders were
willing to participate in risk management. In response to this need, she
explained that EPA worked hard on making the risk assessments transparent
and developed charts and summary documents with USDA. In addition, Ms.
Rossi noted that EPA and USDA have also learned that broad stakeholder
involvement has resulted in sounder risk management decisions, more
creative decisions aimed at risk reductions, and more credible and
workable decisions.
Based on the lessons learned, Ms. Rossi proposed a modified public
participation process. She explained that the modified process integrates
many of the same elements of the pilot process and enhances public
participation at important stages. Ms. Rossi noted that the revised
process is detailed in Staff Paper 42, and described the Phases as
follows:
Pre-Phase 1 - Public Engagement - Inter-agency cooperative effort that
involves the engagement of stakeholders early in the process to ensure
that the risk assessments reflect actual use and usage, available data,
current labeling, and other information on use practices that stakeholders
can provide. Ms. Rossi stated that as part of pre-phase 1, EPA plans to
work with USDA and other agencies like DHHS and FDA prior to Phase 1 to
organize SMART meetings (from the idea of "working smarter")
where the registrant meets with the Agency to explain how the chemical was
used and what data is under development for the risk assessment. She
explained that the SMART meeting is to take place four to six weeks before
the risk assessment begins. In addition, Ms. Rossi noted that EPA and USDA
learned that stakeholders need to have more current information about the
schedules for pesticides in this process. In response to this need, she
noted that EPA would announce for each pesticide the dates for submission
of data and information. Registrants and other stakeholders also need to
help EPA become aware of other ongoing studies.
Phase 1 - Risk Assessment Registrant Error-Only Review, Chemical
Profile, and Inter-Agency Engagement (30 days) - Phase 1 would be the same
as the previous Phase 1. However, Ms. Rossi noted that there would be two
additional activities with regard to the chemical profile and interagency
engagement. In addition, EPA will publish a Federal Register notice to
advise the public about the pesticide that has started the public
participation process including the release of the basic chemical
information.
Phase 2 - Agency Considers Registrant Error Comments (up to 45 days) -
This is similar to the original Phase 2 process with some additions. Ms.
Rossi stated that EPA plans to jump-start the stakeholder involvement two
weeks before the end of Phase 2 at which point EPA will have provided USDA
with a revised risk assessment overview and USDA will schedule
communication, such as a conference call, with stakeholders to review and
discuss the overview. She noted that EPA would work with USDA to address
the suggestions from the stakeholders and comments from DHHS, FDA, and
USDA before the revised assessment is released.
Phase 3 - Public Participation Period: Technical Briefing, Public
Comment on Risk Assessment, and Risk Management Options (90 days) -
Elements of Phase 3 are similar to the original Phase 3, however there are
some modifications. The changes include the release of risk management
options for the same 90-day period and holding a technical briefing for
chemicals with lots of uses, at this time. She explained for pesticides
with limited uses, EPA would offer the option of stakeholder meetings. Ms.
Rossi noted that the same FR notice used to announce the release of the
risk assessment would also be used to announce the availability of options
for risk management and the technical briefing or the stakeholders
meeting. She stated that the technical briefing or stakeholders meeting
would be held at the beginning of Phase 3 to share the revised risk
assessments and the range of possible ideas for risk management options.
As part of this discussion, she indicated that EPA would identify the risk
drivers to help identify potential risk management alternatives. At the
same time, Ms. Rossi indicated that an interagency effort would begin to
engage stakeholders in a dialogue on risk assessment and management
options through means like conference calls to solicit their ideas on
these issues.
Phase 4 - Develop Final Risk Assessments and Risk Management (30-90
days) - Phase 4 would be designed to develop a final risk assessment and
risk management decisions. In this phase, EPA would review and consider
the comments, data and risk management ideas, and proposals received
during Phase 3's public comment period, from stakeholder dialogue,
conference calls, meetings and interactions. She emphasized that the
dialogue with stakeholders would continue through this phase, as well as
being initiated in Phase 3. Ms. Rossi stated that EPA would develop the
revised risk assessment, and with input from USDA, FDA, and DHHS, develop
risk management documents. In addition, at this time, EPA will also
coordinate an interagency senior management briefing to discuss revised
risk assessments and risk management ideas. She stated that, at the close
of Phase 4, EPA would release the revised risk assessment and risk
management decisions for the pesticide in the form of a tolerance
assessment decision or an interim RED.
Ms. Rossi summarized that the modifications proposed in the pilot
process draw on the experiences that USDA and EPA had over the past year.
She stated that, as a result of these experiences they wanted to enhance
the public involvement with pre-phase 1 before the start of the process to
ensure that the risk assessments are using the best and most complete set
of information. Ms. Rossi also noted that stakeholders will also be more
informed because they will know the schedules of the chemicals and when
EPA and USDA need that information so it can be most effectively used. She
commented that Phase 2 would provide the public with advanced information
about the chemicals. Phase 3 would start off with the release of the risk
assessment and some risk management ideas for public comment and technical
briefings or stakeholder meetings to engage the public in discussion of
the risk assessment and risk management. Ms. Rossi noted that the
modifications to the process to eliminate a public comment period in a
preliminary risk assessment, because the assessments that are now under
development are more refined. She clarified that the goal of these
modifications is not to cut time, but to increase the efficiency of the
process. She then turned to Mr. Jennings for his comments on the changes.
Mr. Jennings commented that from their experience in the process, the
length of the preliminary risk assessments was daunting to the LGUs that
they asked to review them. In addition, he indicated that it was unclear
to the entomologists and plant pathologists who were asked to review the
documents, how their crop fit in and what the documents meant. For this
reason, he explained that USDA was performing the first review of these
documents and providing the LGUs with more focused questions about the
risk assessments. Mr. Jennings also observed that EPA wants to know
nationally about the active ingredients and the LGUs are typically dealing
with a registered product that may have different label rates and they
find this confusing. He noted that another problem with the current
process is that there are large chunks of down-time and they think they
should be using it more effectively. In addition, in their review of the
risk assessment, USDA is finding it frustrating to not be able to speak
with the registrant about the risk assessment because at the time of their
review it is a closed process. Mr. Jennings also stated that developing a
greater understanding about the Monte-Carlo analysis is very helpful in
understanding more about the risk drivers which in turn are valuable when
evaluating risk mitigation options. Another issue recognized by Mr.
Jennings was that the technical briefings were limited dialogues because
the stakeholders were seeing the revised risk assessment for the first
time. He noted that the new process would encourage fuller dialogues and
more discussion on the risk management alternatives at the technical
briefings. In summary, Mr. Jennings was supportive of the improvements
proposed by Ms. Rossi and commented that USDA recognized the importance of
opening up the process to all stakeholders.
Following the opening comments, Dr. Ehrmann invited members to comment
and ask questions.
Pre-Phase 1
Several participants supported the addition of pre-Phase 1 because it
promoted early stakeholder involvement. One member was supportive of the
pre-Phase 1 discussions because he saw the value of incorporating the
registrant in the stakeholder discussions for them to learn more about how
their products are used. He felt that it was never too early to involve
stakeholders outside of the registrant in the process. Another member felt
the pre-Phase 1 was a really important step and suggested that EPA could
increase stakeholder motivation to take part by establishing some key
goals that are more generic to help queue up the discussion.
An individual requested clarification on how EPA plans to ensure that
stakeholders and other government agencies are informed and involved in
the process, particularly how EPA planned to interest and involve the
grower groups. Mr. Rossi referenced the process EPA used for the non-OPs
this past year as a potential model, where EPA was ready to make some
decisions and used its Minor Use Team and USDA and a series of conference
calls to get the word out. The individual stressed the need to get
stakeholders involved as early as possible and not to wait for a crisis to
act. One member viewed opening up the risk assessment process to USDA,
DHHS and the stakeholders so they can talk to each other as a tremendous
improvement.
Another member was supportive of the SMART meetings. He commented that
to involve growers effectively in these meetings it would be necessary to
identify the affected grower groups and contact them directly. In
addition, he suggested as a means to increase grower involvement in the
process as a whole, that EPA develop a check list or chart of the process
and publish it in trade journals. The individual also felt that trade
journals could be used to advise growers of the specific chemicals that
are under consideration. One member added that it was also difficult to
find growers with the expertise to help with a risk assessment. In
addition, he regarded the lack of resources as another deterrent to grower
participation in activities like the SMART meetings. As another incentive
for growers to participate, an individual suggested that USDA make
available to growers information on transition strategies for different
crops and for OPs, including reduced risk and non-chemical alternatives.
Phase 1 & 2
A participant requested clarification regarding Phase 1 on whether it
was considered an "error correction" if the registrant disagrees
with EPA's risk assessment conclusion. Ms. Rossi responded in the
negative. The participant commented that registrant's would prefer
including their ability to comment on the accuracy of the risk assessment
as part of "error correction" and observed that that is why EPA
received more than "error corrections" in their responses. He
also felt that this was additional rationale for the registrant to get the
best information in the risk assessment early on in the process.
Many stakeholders were supportive of discontinuing the practice of
requiring a preliminary risk assessment and focusing instead on an initial
refined risk assessment. Some members from the grower community shared
their reluctance to review the preliminary risk assessments because they
felt it was inaccurate and they knew it would be refined. They chose to
reserve their time for the review of the refined risk assessment to
evaluate whether risk management was necessary. One stakeholder agreed
that it was preferable to begin with a refined risk assessment, and that
the risk assessment should be refined prior to involving stakeholders to
minimize the potential for misinformation and confusion. In addition, he
felt it was important to present the document in plain English and in some
kind of condensed format as opposed to 200 pages of material. An
individual stated that EPA did not receive many comments on the
preliminary risk assessment because it did not represent real
circumstances and the results were confusing. A member commented that it
was difficult to deal with theoretical risk and it would be helpful to
provide realistic examples, particularly for a product that has many uses.
As a specific example, another individual noted that the state of
California tried to address the exposure assessment and the environmental
fate characterization in a way that made sense to people to provide them
with an idea about where the greatest risks are.
Several individuals felt that the new process should address not only
the remaining OPs but also other pesticides. One individual suggested that
a necessary part of doing that effectively would be to take the time to
evaluate whether the process which was designed as a framework for
tolerance reassessment of OPs is wholly applicable to other pesticides or
whether it needs to be modified. He also felt that the single most
important factor of a process like this was that it creates accountability
for all of the parties involved. In addition, he observed that this
process has concentrated on dietary aspects and tolerance reassessment. He
noted that there is a universe of people and users and the non-food uses
are not as engaged as the food-use people. The individual commented that
the needs of the individual stakeholders is different and those needs may
dictate when they feel they should become involved in the risk mitigation
discussion.
Phase 3
One individual commented that, at some point in the process, perhaps in
Phase 3 before finalizing risk management options, EPA and USDA should
meet with growers and registrants to discuss how the different interests
in a pesticide come together and what the success or survivability of the
product is relative to some of the uses. As an example, he noted that for
most pesticides, if critical uses were lost, the registrant would not be
able to afford producing the chemical for the remaining uses. The
individual felt that advance warning like this would help registrants plan
better. Another member commented that, for Phase 3 to be done efficiently,
it will be necessary to separate out the discussion on risk assessment and
management and focus on refining the Agency's risk characterization. She
felt that, after this was achieved, it was then appropriate to discuss
risk management alternatives.
Most of the TRAC members felt it was important to separate the risk
assessment review from the risk management discussion. One individual
commented that it is essential to rely on the results of a refined risk
assessment before considering risk management alternatives, to help focus
the effort required in the evaluation of management alternatives,
particularly for crops with many registrations. In addition, he commented
that it is essential to put meaningful effort into finalizing the risk
assessment, including correcting information that is not understood by the
registrant or EPA about how the pesticides are used, and providing
accurate information on where the pesticides will end up as residue. Ms.
Rossi observed that several members referenced the importance of
identifying risk drivers, while at the same time some people commented on
the need to separate the risk assessment process from the risk management
discussions. She noted that risk drivers begin to shift the focus of the
evaluation process towards a consideration of risk management alternatives
and it is hard to totally separate the discussions. Ms. Rossi asked for
additional clarification on the importance of distinguishing between the
two processes.
In response, a participant commented that while it is important to
understand more about the risk through the risk drivers, some of the key
science policies are not resolved and might turn out to affect the major
risk drivers. She commented that it will be hard to have confidence in the
risk assessment process or the results of a risk assessment until all of
the science policies are resolved. For her, risk management suggested
finality and that EPA has made a risk management decision, consequently
she felt it was premature to combine the discussions of risk assessment
and management. Mr. Aidala explained that he interpreted the term
"risk management" as "risk management directions," or
direction implied by the risk driver. He commented that the intention of
the discussion would not be to lock down the management strategy, but
rather to observe, for example, that orange juice is a driver in a risk
assessment and recognize that it is an initial step towards a potential
management strategy, or not. Ms. Murtagh added that many commodity groups,
growers, and LGUs are not sophisticated enough to look at a risk
assessment and anticipate the implications to the use on their commodity.
She commented that these individuals would not engage in the process until
they see what it means to them. Her concern was, if the involvement of
these interests is reserved until the end of the process in the formal
discussion of risk mitigation, they would not have enough time to evaluate
the assumptions made in the risk assessment to arrive at the proposed
mitigation measures. Several members agreed with Ms. Murtagh's comments.
One member felt that the risk characterization should include some
indication of where the risk characterization leads and some indication of
the real world impacts. Mr. Aidala highlighted the idea of "risk
characterization" and stated that it represented a middle ground in
this discussion. He clarified that, whatever it is called, the modified
description of this phase in the process might include a risk assessment
which includes some representation of how the risk cup is impacted, uses
that are influenced, some idea about whether something can be done about
it, and what some of those alternatives might be. A participant suggested
that the risk characterization should go so far as to include an
identification of the drivers with an explanation of why they were
drivers, but it would not include the discussion on potential
alternatives. The participant suggested that discussion on alternatives
would be part of the next discussion on risk mitigation.
Dr. Ehrmann paraphrased what he heard described as the "risk
characterization." He heard that it would be helpful to know what the
Agency believes the risk drivers are, to give a sense of the assumptions
that go into those judgements and some idea of the proportionality between
those drivers. However, he stated that the discussion would stop short of
discussing ideas on how to address those issues and these comments would
be part of the discussion on risk management.
Some members felt the public health concerns were not sufficiently
represented in the process. One member requested clarification on what was
meant by "consultation with DHHS." He hoped that it was intended
to mean consultation on public health issues. In this regard, he observed
that representatives of DHHS have not attended any of the TRAC meetings.
The member was interested in whether the consultation included discussions
on mosquitoes, cockroaches, and rodents. If so, the member noted that he
was unaware of what the DHHS input was. In addition, the member stressed
the importance of including public health risk drivers because, where they
have been discussed, residential risk and worker exposure associated with
residential uses has been high. The member hoped that public health would
be highlighted in the future. He also asked EPA to be more transparent in
terms of how it addressed residential risk assessments, including whether
they assumed worst case scenarios, what the standard operating procedures
and the default assumptions were. Ms. Rossi responded that EPA was taking
guidance from the DHHS on developing a list of public health risks and
that they had addressed mosquitoes, cockroaches, and rodents. Ms. Mulkey
commented that EPA has a Public Health Leader and a Public Health Team who
have made many inroads to DHHS. She explained that the DHHS has indicated
that their capacity to take part in the TRAC has been limited by
resources. Ms. Mulkey also observed that at each technical briefing, EPA
has highlighted in their documents the interplay between the risk
assessment, including residential exposure, and science policy issues.
Another individual stressed that it was very important in the risk
assessment process to identify risk drivers in the public health area
because as end use formulators, the pest control industry is subject to
the economic realities and consequences that are being faced by the
chemical producers and manufacturers of the active ingredients. For that
reason, he stated that it is possible that the non-agricultural uses could
be forced out of the risk cup. A participant added that it was also
important to have monitoring and surveillance programs to point out some
of the successes of risk management programs.
One individual commented that his experience with the stakeholder
meeting in Florida was good. He also suggested that the Agency consider,
as an alternative to written comments, site visits to speak with the
people involved with agriculture in the field as another method of gaining
a better understanding of the potential impacts of some of the mitigation
measures.
Phase 4
A participant suggested adding an element of review to Phase 4 or some
other appropriate place in the process. He observed that, as we progress
with the process and have a series of mitigation measures in place, it
would be useful to have an evaluation loop to compare the effectiveness of
existing risk management measures. The participant expressed the concern
that, without this sort of mechanism, the agricultural community may end
up with very few materials for use at the end of a season and be left with
inadequate alternatives for pest control. Another individual commented
that there is a need to have a smaller group evaluate this suggested
process and propose some more specific recommendations to flesh out some
of the areas that would enhance the process.
General
An individual asked if USDA felt that the modifications to the process
addressed the concerns about the inefficiencies of the pilot process. Mr.
Jennings responded that the modifications would address these concerns,
particularly because they move their involvement away from a paper
exercise and the process is more open. The individual suggested that,
whatever process is agreed on, that the timing of decision making be
considered. He suggested that EPA and USDA avoid making last minute key
decisions.
A participant suggested that the new process include a place for
discussing benefits considerations and factoring in ecological, worker and
other kinds of FIFRA risk issues at the same time that REDs are submitted
to the public participation process. In addition, he observed that one of
the reasons the TRAC process was started was because of experiences with
the Freedom of Information Act (FOIA). In this regard, he wanted to know
whether EPA had observed a change in activity regarding FOIA. Mr. Aidala
responded that he was uncertain about the activity regarding FOIA. Ms.
Mulkey added that she thought stakeholders had generally accepted the
public participation process as a means by which they will obtain their
information; however, she also did not know specifically about the status
of FOIA activity. The participant felt that some idea of relative FOIA
activity should be part of evaluating the process.
Another participant stated that the timing of the AZM and PM review was
unfortunate because it was at the busiest time of the year for the LGUs
and it was difficult for them to find the time to review the material. He
acknowledged that the material in the risk assessment, particularly the
toxicology, is challenging and difficult to understand and suggested that
EPA and USDA coordinate an education program to bring stakeholders up to
speed on this information through the pest program and OPMP. He also
commented on some of the state, regional and national network challenges
that this kind of program presents in terms of out-reach to the affected
commodities. In addition, the participant noted that it is hard to
anticipate the type of bridging data that EPA needs on specific chemicals
and the process of providing it is resource intensive. He stated that with
the move towards bridging data, LGUs have experienced an increase in FOIA
requests for which they are not well prepared. In particular, he noted
that they are challenged by the necessity to protect the contributors of
the bridging data. To use bridging data effectively in the risk assessment
and risk management processes, the participant felt that EPA needs to
reach out to a broader network of resources beyond the LGUs and
commodities; to the state agencies, processors and others.
A member commented that the Federal Register notices are not the best
way to inform stakeholders about upcoming events. As an alternative, she
suggested using something like an electronic mail (e-mail) group code,
which she has found to be successful. The participant offered to share the
e-mail group that includes commodity, LGU, state agencies and other
individuals who have contacted them with EPA as a resource and an
additional means of outreach. She also stated that it would be helpful to
registrants if EPA could let them know when they receive information from
registrants for the risk assessment, whether the Agency - accepts the
information or if they need more.
One individual commented on the limited amount of focus on the
alternatives for growers who would be affected if an OP were taken off the
market. He felt the available information on alternatives was not very
sophisticated and he hoped this group would spend more time on developing
more alternatives from which to draw.
An individual stated that EPA should include more information than is
currently provided about pesticides and dried foods. Mr. Aidala stated
that EPA agreed with this suggestion. The participant felt that this might
also be a subject for a workshop.
Post-TRAC Activities
Dr. Ehrmann initiated the discussion on post-TRAC activities and
reminded participants that EPA and USDA planned to listen carefully to
their comments and suggestions on options for post-TRAC activities, but
did not plan to make any decisions regarding next steps at this meeting.
Many TRAC members felt that there should be some forum for ongoing
stakeholder activities following the TRAC. They felt the forum should
include continued transparency of Agency and Department actions and
processes. Some of the specific suggestions are presented below:
Define a role for and include DHHS in the regulation of public health
pesticides.
Continue to standardize and implement a public participation process to
address risk assessment and risk management actions.
Clarify the policy for pesticides that are potentially carcinogenic.
Identify the uncertainties associated with timing of tolerance
revocations and application of the FQPA safe harbor provisions for treated
food products in the channels of trade and recommend a policy.
Determine a forum for resolving issues associated with worker
protection from pesticides.
Determine critical needs for reliable data in risk assessments under
FQPA to avoid use of default assumptions and establish regulatory
mechanisms for obtaining data.
Establish a process to assess and review risk management actions and
their refinements after they are developed.
Finish developing the FQPA science policies.
Continue to enhance USDA's decision making process in pesticide
regulations and in handling input from growers and other pesticide users.
Evaluate the economic impact of FQPA implementation on affected
industries.
Further define acceptable transition strategies.
Compromise on the future forum for stakeholder activities and develop
something that is less resource intensive for the Agency and the
Department than the TRAC.
Have a TRAC-like group meet less frequently and utilize work groups
that would meet on a more frequent basis to address selected issues. They
would address issues like the remaining science policy issues and
transition. Additional suggestions for the work groups -- focus on risk
characterization and transparency to help people understand the framework
in which risk mitigation takes place.
Maintain the same level of senior involvement. Include DHHS at that
level also.
Assure more predictable time frames.
Call the group CART - Committee for Advising on Reregistration and
Transition.
Invite renewed participation from the environmental and public interest
communities.
Continue to deal with other unfinished business like public health
risk.
Convene a workshop for non-agricultural partners to educate them about
the process and get input from them.
Remain focused on assuring the world's safest, affordable, abundant
food supply.
Avoid shifting the playing field for agriculture to outside of the U.S.
Guarantee accountability and an effective way to exchange information.
Maintain a workable size committee with all of the interests
represented.
Include benefits in the discussion.
Get around to implementation.
One individual raised the question about whether the future should
include a formal advisory committee.
Following this discussion on post-TRAC activities, Dr. Ehrmann invited
members of the public to comment.
Public Comment
Dr. Gabriel Ludwig, Western States FQPA Coalition - described the
membership of the Western States FQPA Coalition and explained that the
membership covers approximately 50 percent of the professional fruit
production in the country. He observed that the intense participation of
EPA, USDA and members of the TRAC has increased the understanding of what
is necessary to implement the FQPA. He noted that the TRAC helped to
increase public understanding of dietary and occupational health risk
assessments and greater transparency has provided growers with the option
of participating earlier in the process. He stated that because of the
positive impact of TRAC, the Coalition encourage the continuation of some
form of TRAC to address issues including transition, risk mitigation, and
the remaining science policy issues.
Gail Ors, Toxicologist with Griffin - requested that EPA extend the
SMART meetings, which she felt were helpful and provided an opportunity
for dialogue, to begin to discuss the toxic endpoints. She noted that a
higher committee makes the decisions on endpoints, and opening the
discussions would be more transparent. In addition, she observed that the
selection of a study to match an endpoint is not always a logical
decision. Often, she stated the decisions are subjective and are made in
terms of a NOEL, and the selection of a NOEL depends on the agencies
making the selection. She felt that the decisions on endpoints should be
made in SMART meetings and open to discussion.
Vern Highle, Executive Committee of the Minor Crop Farmer Alliance and
Other Organizations - commented on behalf of his clients and the
National Watermelon Association, recognized the importance of safe food.
He felt that, if EPA is not careful, they risk the possibility of
compromising the diet of one third of the world's population. He thanked
the farmers for their participation because they are representing the
interests of other farmers whose livelihood might be compromised by the
loss of some of the chemical pesticides. He also thanked the agricultural
allied interests who spoke in support of agricultural interests and
thanked OPP staff for their work on the process. Mr. Highle was supportive
of continuing a stakeholder forum of some kind.
Wrap-up and Closing Remarks
Mr. Rominger thanked TRAC members for their commitment to the process
because he felt it had made a difference. He stated that a lot of topics
were addressed over the course of the meeting, including updates on what
had transpired since the last TRAC meeting, a status on the OPs, and
transition issues. He commented that the remarks of the Southeast Apple
Foundation for transition strategies were helpful. In addition, Mr.
Rominger characterized the discussion on channels of trade as an important
one which deserved additional discussion between the UDSA, EPA and the FDA
for resolution. He felt the input on the public participation process was
constructive and would serve to open the process up for earlier input in
addition to focusing comments on more refined risk assessments. Mr.
Rominger also recognized that, while some felt the public input process
was not as inclusive as it could be, some individuals from outside the
TRAC process were included in the workshops. He then commented on what he
saw as next steps following the TRAC meeting. He felt a number of good
points were made to support the need for some kind of process that would
allow additional stakeholder input on the tough issues and decisions that
have to be made. He commented on the ideas of using work groups and
workshops could also be beneficial and would be considered for future
activities. Mr. Rominger concluded his remarks by stating that, while
there was no decision on whether a future process would involve a FACA
committee or some other type of process, it was clear that there was a
need for a continuing dialogue and stakeholder involvement. He thanked EPA
for their efforts to make the partnership between EPA and USDA work and
committed to build on the partnership and involve more of FDA and HHS in
the process. Mr. Rominger reaffirmed his, Secretary Glickman's, and USDA's
continued commitment to the process.
Mr. Guzy commented that, before TRAC, stakeholders did not have a clear
understanding of how EPA made decisions, whether the basis for their
decisions was scientific, and whether EPA was commitment to the children's
health provision in FQPA. He observed that, through the TRAC process, the
decision making process and the basis for decisions is clearer and there
is a sense that, while EPA is serious about public health protection and
children's health, it is also committed to moving forward in a responsible
and reasonable way. He stated that, because of the TRAC and its
partnership with USDA, EPA is making and will make better decisions. Mr.
Guzy also commented that he heard many valuable comments on the need for
an ongoing process and that EPA was committed to working with the Meridian
Institute and other stakeholders not at the table for their input on this
need. He stated that both EPA and USDA continue to believe that, through a
workable process, whether it is a FACA process or not, constructive,
meaningful, sustained communications with stakeholders on these issues is
vital. In addition, Mr. Guzy felt that a strong partnership between EPA
and USDA was essential to EPA's ability to implement FQPA effectively. He
observed that, while the initial focus of the TRAC was on OPs, there was
still a significant amount of work to be done to address other substances
covered by the FQPA and a need to expand the pilot process for this
purpose.
Mr. Guzy also commented that transition was a key topic and that EPA
will continue to support USDA's efforts to develop reasonable transition
strategies. He stated that, as announced by Administrator Browner on
August 2, 1999, EPA will meet the challenge of risk reduction, and is
committed to approving newer and safer products in a timely way. In this
regard, Mr. Guzy felt there were many opportunities for stakeholders to
develop voluntary transition plans that are responsive to all concerns. He
stated that, regardless of the structure chosen for future stakeholder
activities, EPA is committed to following the TRAC design process of
notice and comment to bring to closure the nine science policies and
future science policies. Mr. Guzy noted that, based on the discussion at
the meeting, EPA plans to propose enhancements to the public comment
process within the next 30 to 60 days. He observed that public confidence
in the review process was essential, and it is critical for EPA to strike
the right balance between error correction, adequate documentation and
transparency in the process. On behalf of Administrator Browner, EPA
senior leadership and staff, Mr. Guzy commended members for their
commitment to the challenging process. He noted that the future process
would also require a similar commitment and continued constructive, good
faith engagement.
Mr. Guzy stated that EPA knows that they need to listen, communicate
and reach out more effectively and be vigilant to the four principles laid
out at the start of the TRAC: transparency, sound science, consultation
with the public, and reasonable transition strategies. Mr. Guzy also
observed that others who were not a part of the process would also need to
demonstrate a commitment to constructive input and dialogue. He asked the
TRAC to be patient with EPA and to continue to demonstrate understanding
that EPA is implementing FQPA to assure that the U.S. food supply is the
best and safest in the world. Mr. Guzy recognized that one of the most
important results of the TRAC was the partnership between EPA and USDA. He
thanked Deputy Secretary Rominger for all of his work and acknowledged
that Secretary Glickman was also supportive and committed to this effort.
Mr. Guzy also thanked EPA staff for their tremendous effort in the
process, and expressed gratitude to the Meridian Institute for their help
working through the issues, and to TRAC members for their commitment to
the process.
The meeting was adjourned.
