## Introduction  Preliminary ef

fects determination by taxa table.  Screening assessment identifies May Af fect (next slide) ...  One approach to refining number of chemical/species interactions might be through biological exclusions.  GIS analysis intensive  Greatly reduces (eliminates?) species of concern  Alternatively;  Filtering – we think this will eliminate many May Af fect situations.  A step after filtering might be a simple proximity approach.

## GIS/EO Exclusions  Biological exclusions by species in theory eliminate chemical/species interactions by identifying species where there is no overlap with chemical use. **Associated challenges:**   obtain resolution that would be commercially acceptable  determining mutually acceptable proximity datasets  There may be alternative approaches to achieve the same intent

## Proximity**T**

**ool**  Development of a proximity tool based on FESTF MJD NatureServe location data, Google Maps and an ARCGIS method.  The tool requires a 2 bits of information from the label: 1) An EP

A problem formulation that defines taxa of concern (e.g. monocots)=>> Leading to taxa **labeling** (e.g. dicots) 2) An EP

A derived spray buf

fer distance for protection of those species (e.g. ‘200 to obtain an NOEC/EC 25 

### ) =>> Risk based spray buf

fers.

## How the proximity**t ool would/might**  **work**  An applicator (user) would log onto the website prior to making an application.  Next the user would select the taxa of concern and enter the required buf fer distance (from the label).  Next the user find the field they want to apply to, drag the field with one of the two selection tools (Google map ARC - GIS.)  Once the field is selected the buf fer is drawn, and a notice pops up if there are any proximity concerns. Additionally the field is symbolized red in the direction of the proximity concern (if one exists). If the field is totally red this means the field is located within an EO.

Displa ying the location of E O’ s has been a concern with tool discussions. The tool could allow displa ying E O’ s only when a passwor d has been ent er ed to pr ot ect these locations.16 No zzle, Re lease Height, Buffer Distance and What buffer ed to

## Refinement **?** 

# Step 1 • Risk Based Buf fers to: Non - Ta rget areas “Grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, and shrub lands.” **To o**  **broad ! !**  

# Step 2 • EP

A’ s new D RT Process to reduce base case buf fers in step 1 and filtering !!! 

# Step 3 • Proximity Analysis to eliminate buf fer concern but this is too much information for county bulletins – this would require an ArcMap server like EP A’ s surf your wa tershed for local – field level specificity.
