ENVIRONMENTAL PROTECTION AGENCY

[OPP-00540; FRL-5798-2]


FIFRA Scientific Advisory Panel; Open Meeting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: There will be a two-day meeting of the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA) and Food Quality Protection Act 
(FQPA) Scientific Advisory Panel (SAP) to review a set of scientific 
issues being considered by the Agency in connection with the FQPA 10x 
Safety Factor, Linear Low Dose Extrapolation for Cancer Risk Decisions, 
Proposed Methods for Basin-Scale Estimation of Pesticide Concentrations 
in Flowing Water and Reservoirs for Tolerance Reassessment, DDVP 
(Dichlorvos)and Chlorothalonil. The Agency will present a status report 
of the FQPA 10x Safety Factor, as requested by the SAP at the March 25, 
1998, SAP meeting. For the cancer risk assessment session, the Agency 
will discuss the issue that due to uncertainties and variabilities 
surrounding input measures, estimates of carcinogenic risk using linear 
low dose extrapolation should be presented in a manner that reflects 
the precision of the estimated risk. The precision of the risk estimate 
can be no better than that for the least certain input parameter into 
the model. Representation of additional significant figures in risk 
estimates may introduce false precision into risk management decisions. 
The Agency will also present a session evaluating and developing 
improved methods to allow for basin-scale estimation of pesticide 
concentrations in surface waters used as drinking water. As an interim 
approach, the Agency is developing a reservoir scenario as a 
replacement water body for the standard small water body currently used 
in ecological exposure assessments and drinking water exposure 
assessments. The reservoir scenario is being developed to be 
representative of an actual reservoir which serves as a drinking water 
supply for a rural community. Additionally, the Agency is critically 
evaluating basin scale models and developing linkages of field scale 
models to estimate pesticide concentrations in flowing surface waters 
and reservoirs. Two sessions are scheduled for pesticide specific 
discussions. The first session will focus on two issues concerning the 
chlorothalonil human health risk assessment: (1) mechanism for the 
formation of renal and forestomach tumors and; (2) calculations for 
acceptable margins of exposure. The second pesticide for discussion is 
DDVP (dichlorvos). For this session, the Agency will present the DDVP 
risk assessment.

DATES: The meeting will be held on Wednesday and Thursday, July 29 and 
July 30, 1998, from 8:30 a.m. to 5:30 p.m.

ADDRESSES: The meeting will be held at: Embassy Suites Hotel, 1300

SUPPLEMENTARY INFORMATION: Any member of the public wishing to submit 
written comments should contact Larry C. Dorsey at the address or the 
phone number given above to confirm that the meeting is still scheduled 
and that the agenda has not been modified or changed. Interested 
persons are permitted to file written statements before the meeting. To 
the extent that time permits and upon advanced written request to the 
Designated Federal Official, interested persons may be permitted by the 
Chair of the Scientific Advisory Panel to present oral statements at 
the meeting. There is no limit on the length of written comments for 
consideration by the Panel, but oral statements before the Panel are 
limited to approximately five minutes. As oral statements only will be 
permitted as time permits, the Agency urges the public to submit
