Getting the Feet Wet in EIGrant work plan in 2001

Started on EI in Spring 2002

Gathering data, exploring categories

Windshield surveys

Internet searches (EPA, State sites)

Did a GIS map for a visual aid

Realized it was a HUGE task and one that needed more time and staff

The Help of TEISSIntroduced to TEISS in Fall 2002

Training in Spring 2004 at FDL Rez

Great Tool !!!Simplifies EIHelps investigate emission sources and

data needed for EI (calculators)Create maps, graphs, tables, reports

First Round DONE!!!

Submitted 2002 EI to ITEP for QA/QC

Make changes if needed

Will have ITEP submit Leech Lake’s EI to the NEI

~~~~~~~~~~IT’S NOT DONE~~~~~~~~~

Keep eyes open

Prepare for EI update

The EndIt is a complex project

Allow enough TIME

You set the scale/area for the EI

Grab data as it is presented to you, you will never know when it may prove to be useful

TEISS makes it a more attainable task

Tribes can accomplish their own EI

Encourage all to do an EI for your Rez
