1. Worker Protection Measures Tarp Perforation and Removal and Entry Restrictions John Leahy, EPA Pesticide Re-evaluation Division

2. 2 Tarp Perforation and Removal Perforation 5 days after fumigant application is complete By mechanical means Removal 2 hours after perforation is complete Planting Less than 14 days after application: – Plant 48 hours after tarp perforation is complete 14 days or more after application: – Perforate and plant simultaneously

3. 3 Early Tarp Removal and Perforation Early removal (before 5 days) for broadcast applications is allowed – if adverse weather conditions (i.e., high wind, hail, storms) have compromised the integrity of the tarp and the tarp poses a safety hazard. Early perforation is allowed for flood prevention activities – Tarps must be retucked and packed after soil removal

4. 4 Entry Restricted Period Current labels allow reentry after 48 hours Fumigant dissipation rate highly variable (soil conditions, application method, tarp type, etc.) Reentry time lengthened Entry Restricted Period ≠ REI

5. 5 5 Entry Restricted Period: Untarped Applications Shank Untarped Drip Untarped Center Pivot 5 days after application is complete

6. 6 Entry Restricted Period: Tarped Applications If tarps are perforated and removed less than 14 days after application, entry into the treated area is prohibited until the tarps are removed.

7. 7 Entry Restricted Period: Tarped Applications, Perforation < 14 days If tarps will not be removed for at least 14 days after the application but they will be perforated before 14 days, entry into the treated areas is prohibited until 48 hours after tarps are perforated.

8. 8 Entry Restricted Period: Tarped Applications, Perforation > 14 days If tarps are perforated and/or removed at least 14 days after the application is complete, entry into the treated area is prohibited for 5 days
