Reregistration Eligibility Decisions (REDs)

• Re‐licensing decisions for chemicals used as soil

fumigants – Methyl Bromide – Chloropicrin – Metam Sodium/Metam Potassium – Dazomet

• First comprehensive re‐evaluation since products first

registered

3

Overview ‐ Goals

• Protect workers and bystanders while

y maintaining key benefits of use

• Ensure a level playing field across all soil

Ensure a level playing field across all soil fumigants

• Make risk management decisions that are
• Make risk management decisions that are

protective and that take into account likely real‐world outcomes

development New handler protections including changes to respiratory protection, tarp cutting/removal and worker reentry restrictions

• Safe handling information

Fumigant management plans and post application summaries

• Difficult to evacuate sites
• Notice to state lead agencies
• Notice to state lead agencies

Certified applicator training, first responder, community outreach

Data on Acute Illnesses

• Data obtained from Sentinel Event Notification System for

Occupational Risks (SENSOR) ‐Pesticides Program and the CDPR (1998–2006)

• Cases

‐ 11 states 11 states ‐ 2.945 illnesses ‐ 643 “drift” events (including volatilization)

• Fumigants
• Fumigants

‐ Small percent of events (8%) ‐ Largest proportion (44%) of illness cases g p p ‐ Common factors: weather issues, improper measures to prevent fumigant from escaping, and applicator carelessness

2008 Washington Incident

• In 2008; 35 gallons/A of Metam 42% CLR product applied to 150

acres field using center pivot after harvest

g

acres field using center pivot after harvest

• Family of 17 lived 380 ft from field
• 19 reported symptoms (including sheriff deputy)
• 12 sought medical attention (including 2‐week old infant)
• WA Dept of Health ‐ contributing factors were:
• WA. Dept. of Health ‐ contributing factors were:

‐ Inversion conditions ‐ Low wind speed (< 2 mph) H d di (150 f d d l ) f fi ld ‐ Home down gradient (150 ft drop down slope) of field ‐ Inadequate field preparation (crop residues in field) ‐ Residents unaware of application pp ‐ Improper emergency response

8

2008 Washington Incident

• Home located with 380 ft would be in the buffer zone

Relevant Mitigation

Home located with 380 ft would be in the buffer zone and application scenario from incident would be prohibited unless occupants provided written agreement to voluntarily vacate home during buffer zone period voluntarily vacate home during buffer zone period

• New labels have specific requirements related to wind

speed, weather, and indentifying unfavorable weather p , , y g conditions

• Depending on size of buffer and proximity to homes,

applicator is required to either monitor the air between the buffer zone and homes or provide response information to the neighbors

9

2010 Idaho Incident

• 99% chloropicrin product applied to 2 fields (25 acres

and 75 acres) application method was shank bed and 75 acres), application method was shank bed untarped

• People at a drive‐in theater (surrounded on 3 sides by

p ( y the fumigated fields) complained of burning eyes and trouble breathing

• Once the fire department arrived, people were NOT

permitted to leave the theater d b f d f l l

• Reported contributing factor, end‐of‐row soil sealing

10

2010 Idaho Incident

Relevant Mitigation

• New labels have Good Agricultural Practices (GAPs)
• New labels have Good Agricultural Practices (GAPs)

that address soil sealing and prevention of end row spillage

• Registrants will be required to provide emergency

responders, in high fumigant use areas, information d i i i l d and training materials necessary to respond to fumigant incidents

• Emergency Response Plans must be included in the
• Emergency Response Plans must be included in the

Fumigant Management Plan (FMP) which identifies emergency procedures and responsibilities

Enforcement & Compliance Guidance

C li i t i 2011 2012

• Compliance assistance in 2011‐2012

‐ Work with users to help understand labeling and how to comply

• Compliance monitoring in 2012‐2013

‐ Ensure compliance with labeling

• Response to complaints

‐ Label violations? Egregious? J d d d ‐ Judgment needed
