• EPA, Michigan, and other Region 5 States working together
• Stakeholder Involvement – Four meetings– Sub workgroups
• General Permits– Federal vs. State
• Notice of Intent• Certificate of Coverage

Annual Treatment Area Thresholds
Pesticide Use Annual Threshold
Mosquitoes and other flying insect pest control 640 acres of treatment
Aquatic Nuisance Plant and algae control
In Water 20 acres of treatment
At Water’s Edge 20 linear Miles of treatment
Aquatic Nuisance Animal Control
In Water 20 acres of treatment
At Water’s Edge 20 linear Miles of treatment
Forest Canopy Pest Control 640 acres of canopy
Treatment Area CalculationsArea of applications made to: 1) water’s of the state of Michigan, and 2) conveyances with a hydrologic connection to surface waters of the state during the time of pesticide application.
For calculating annual treatment area totals,– Count each pesticide application as a separate activity.
Also, multiple treatments to the same area are considered as distinct pesticide application events.
• For example:– a 5-acre treatment area that is treated 4 times in one year
equals 20 acres of treatment area, and
– treating both sides of a ten mile ditch is equal to twenty miles of treatment area.
Permittee
• Decision-maker and/or person financially responsible, or person applying pesticides– Michigan approach – One permittee
– Clear division of responsibility• Written agreement between parties
• Applications Under threshold– Automatic coverage– No application required
Michigan’s Permitting Approach• Separate General Permit for each category
– Mosquito and flying insect pest control– Aquatic nuisance weed and algae– Aquatic nuisance animal– Forestry canopy pest control
• Acknowledge existing programs– FIFRA– Rule 97 certifications– Aquatic Nuisance Control – Part 33– Agriculture – Part 83– Reporting– Procedures
General Permit Requirements
• Components that make up General Permit– Discharge Limitations
– Integrated Pest Management Practices
– Pesticide Discharge Management Plan
– Record Keeping/Annual Report
• Adverse Incident Reporting
• No numeric limits
www.scerp.net
Discharge Limitations
• Minimize pesticide use
• Equipment maintenance/calibration
• Spill prevention
• Registered products
• Specific restrictions
• Listed pesticides
www.thefullwiki.org/Pesticide
Integrated Pest Management Practices
• Only required if exceed annual threshold• Identify species and contributing factors• Pest action threshold• Pre- and post-application surveillance• Select/implement effective pest
management• Compliance
– Pre-existing plans– Document implementation
www.dbw.ca.gov/Environmental/Aquatic.aspx
Pesticide Discharge Management Plan
• Only required if exceed annual threshold– Deadlines for development
• Documentation of limit implementation– Evaluation/selection of control measures– Does not contain limitations
• Division of duties – written agreement• Record retention• Modification
– Corrective action– updates
Record Keeping
• Required for all permittees– Minimal requirements if below threshold– Exceed threshold – more comprehensive
• Acknowledge other program requirements– Eliminate duplication
• Record retention– 3 years– Availablity
Annual Report• Required only if exceed annual threshold• Summary of pesticide application activities
– Treatment area Specific
• Submittal requirements– Can rely upon other documents to fulfill conditions of
reporting requirement
www.lakelandrs.com/Technical_Services.aspx plants.ifas.ufl.edu/node/191
Requirement for Individual Permit
• Pesticide not listed
• Significant contributor to pollution• Outstanding state resource waters
• Impaired waters
• Permittee request
www.aaroncjors.com
Permit Application and Forms• Proposed Format
• Application Training Workshop• Tentative: February 10, 2011
Compliance• Paramount Issue
– Staffing and cost– Number of permits to process– Unsure of approach
• Rely on Existing Program Requirements• Adverse Incident Report• Corrective Action• EPA Guidance
– Expectations?
Current Status and Next Steps• Draft General Permits Completed• Public Notice
– 30 day comment period• Newspaper• DNRE website
– Concurrent Hearing Announcement• Continue Public Outreach• General Permit Issuance in December• Document Development
– Annual Report– Permit Application
• Issue Certificates of Coverage• Compliance
