ENVIRONMENTAL PROTECTION AGENCY
[OPP-34238; FRL-6775-8]
Organophosphate Pesticides; Availability of Risk Management
Decision Documents
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.

-----------------------------------------------------------------------
ethyl parathion (Parathion), phorate (Thimet), phosalone (Zolone), and
temephos (Abate)/Insecticdes

SUMMARY: This notice announces the availability of the risk management
decision documents for four organophosphate pesticides, ethyl
parathion, phorate, phosalone, and temephos . These decision documents
have been developed as part of the public participation process that
EPA and U.S. Department of Agriculture (USDA) are now using for
involving the public in the reassessment of pesticide tolerances under
the Food Quality Protection Act (FQPA), and the reregistration of
individual organophosphate pesticides under the Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA).

What Action is the Agency Taking?

EPA has assessed the risks of Ethyl Parathion, Phorate, Phosalone,
and Temephos and reached a Reregistration Eligibility Decision (RED),
an Interim Reregistration Eligibility Decision (IRED), or a Report on
FQPA Tolerance Reassessment Progress and Interim Risk Management
Decision (TRED) for each of these organophosphate pesticides.
1. Ethyl Parathion RED. All remaining uses of Ethyl Parathion are
being voluntarily canceled and phased out during the next few years.
Because no uses will remain, Ethyl Parathion will not be included in
the cumulative assessment of the organophosphate pesticides.
2. Phorate IRED. With the adoption of additional risk mitigation
measures, Phorate fits into its own risk cup; its individual, aggregate
risks are within acceptable levels.
3. Phosalone TRED. With no U.S. registrations and import tolerances
only, Phosalone fits into its own risk cup without additional risk
mitigation.
4. Temephos RED. With risk mitigation measures adopted, Temephos is
eligible for reregistration. Because it has no food uses or other uses
that result in exposure to children, Temephos will not be included in
the cumulative assessment of the organophosphate pesticides.
The risk management decision documents for ethyl parathion,
phorate, phosalone, and temephos were made through the organophosphate
pesticide pilot public participation process, which increases
transparency and maximizes stakeholder involvement in EPA's development
of risk assessments and risk management decisions. The pilot public
participation process was developed as part of the EPA-USDA Tolerance
Reassessment Advisory
Committee (TRAC), which was established in April 1998, as a
subcommittee under the auspices of EPA's National Advisory Council for
Environmental Policy and Technology. A goal of the pilot public
participation process is to find a more effective way for the public to
participate at critical junctures in the Agency's development of
organophosphate pesticide risk assessments and risk management
decisions. EPA and USDA began implementing this pilot process in August
1998, to increase transparency and opportunities for stakeholder
consultation.
EPA worked extensively with affected parties to reach the decisions
presented in the risk management decision documents, which conclude the
pilot public participation process for ethyl parathion, phorate,
phosalone, and temephos . As part of the pilot public participation
process, numerous opportunities for public comment were offered as
these risk management decision documents were being developed. The
ethyl parathion, phorate, phosalone, and temephos risk management
decision documents therefore are issued in final, without a formal
public comment period. The docket remains open, however, and any
comments submitted in the future will be placed in the public docket.
The risk assessments for ethyl parathion, phorate, phosalone, and
temephos were released to the public through the following notices
published in the Federal Register:
1. Notices for ethyl parathion were published on January 15, 1999
(64 FR 2644) (FRL-6056-9) and March 1, 2000 (65 FR 11050) (FRL-6494-8).
2. Notices for phorate were published on August 12, 1998 (63 FR
43175) (FRL-6024-3) and September 1, 1999 (64 FR 47784) (FRL-6099-9).
3. Notices for phosalone were published on January 12, 2000 (65 FR
1867) (FRL-6486-9) and July 26, 2000 (65 FR 45982) (FRL-6737-3).
4. Notices for temephos were published on September 9, 1998 (63 FR
48213) (FRL-6030-2), December 18, 1998 (63 FR 70126) (FRL-6052-6), and
October 6, 1999 (64 FR 54298) (FRL-6387-6).
EPA's next step under FQPA is to complete a cumulative risk
assessment and risk management decision for the organophosphate
pesticides, which share a common mechanism of toxicity. The interim
risk management decision documents on phorate and phosalone cannot be
considered final until this cumulative assessment is complete. The
ethyl parathion and temephos REDs represent the Agency's final
decisions for these pesticides under the organophosphate pesticide
review process.
When the cumulative risk assessment for the organophosphate
pesticides has been completed, EPA will issue its final tolerance
reassessment decision for phorate and phosalone, and further risk
mitigation measures may be needed.
