PA Pesticide Program Updates: December 11, 2001Pesticide Program Update from EPA's Office of Pesticide Programs, December 11, 2001 IN THIS UPDATE:
EPA Closes Telone Special ReviewEPA has published a notice terminating the Special Review of the pesticide Telone (1, 3-dichloropropene). Telone is a pre-plant soil fumigant used mainly to control plant-parasitic nematodes. Telone is registered for use on all vegetables, fruit and nut crops, all forage crops (grasses, legumes and other non-grass forage crops), tobacco, all fiber crops and all nursery crops (ornamental, non-bearing fruit/nut trees and forestry crops). It is classified as a non-food use pesticide because studies show that no residues are present in crops grown on treated soil (and thus there are no tolerances or exemptions from the requirement of a tolerance).This notice is based on the January 12, 2000, publication of the Telone Position Document 2 (PD 2) (Federal Register Volume 65, No. 8, Pages ). The PD2 proposed to close out the special review for Telone without any further regulatory action. Since the initiation of the special review in 1986 based on cancer concerns for workers, the Telone registrant, Dow AgroSciences, has submitted additional worker exposure and air and water monitoring studies and implemented a range of measures to mitigate risks to workers and to residents in areas where Telone is applied. Mitigation measures include: Label changes to reduce levels of Telone that volatilize into the atmosphere during fumigant transfers, application, and the post-fumigation time period; Requirements for shut-off valves to prevent Telone from spilling at row turns, closed loading, soil sealing, a 300-foot no-treatment buffer from occupied structures, improved product stewardship, a phase-out of drum delivery, and reduced application rate; Modification of the Telone registration to prohibit use in certain northern tier states based on ground water concerns, a 100-foot no-treatment buffer around drinking water wells, prohibit use in areas overlying karst geologies, and require additional monitoring to confirm that use of Telone does not pose unreasonable risks when used according to product labels. Based on EPA's review of new data and the addition of these mitigation measures, EPA has concluded that the use of Telone will not cause unreasonable risks to human health or the environment and that all labeled uses are eligible for reregistration. The Telone Reregistration Eligibility Decision (RED) document was published in December 1998. As the Agency's risk concerns have been addressed through a series of label amendments, product stewardship, and ongoing monitoring, the Agency is terminating the Telone Special Review. The Federal Register notice is available on EPA's web site and includes a response to comments received on the January 2000 notice. The RED is posted on the web site.
