Check the pesticide label for these requirements
- Mandatory spray-drift mitigations.
- Mandatory runoff mitigation measures, noting the number of points you need to comply.
- If mitigation measures are limited to specific geographic regions, the label will direct you to check the U.S. Environmental Protection Agency, Bulletins Live! Two website (https://www.epa.gov/endangered-species/bulletins-live-two-view-bulletins).
Calculate total number of points for a given field
- Use the EPA’s mitigation point calculator (https://www.epa.gov/pesticides/runofferosion-mitigation-calculator) to determine the total number of points achieved for each field where the pesticide will be applied. The Google Chrome browser is recommended for the calculator.
- PDF and Excel versions of the calculator can be found under ESA resources in the Additional Resources section.
- Determine whether you have enough points, and if not, implement additional mitigation measures to reach the target.
Check Bulletins Live! Two
- Check the U.S. Environmental Protection Agency, Bulletins Live! Two website (https://www.epa.gov/endangered-species/bulletins-live-two-view-bulletins) within six months of herbicide application.
- To view the bulletin, enter the location, date, and pesticide registration number for a given product.
- Review the bulletin to determine if any additional mitigation measures are required. The bulletin may or may not impose additional limitations.
Save results for records
- It is not required, but it is recommended that these documents be saved in a printed or electronic format. Both the EPA calculator and Bulletins Live! Two offer the option to download a PDF.
- In the event of off-target movement, documentation ensures compliance can be verified.
