Red Lake Band of Chippewa• 837,000 acres• 2% of Diminished

Reservation lands developed

• 10,000 Band members, 6,500 live on reservation

• Historically, commercial fishing and logging two biggest industries

Air Program Development

• Received GAP funding in late 2007 to begin program, transitioned to CAA 103 funding

• Began EI in early 2008 for the calendar year 2007– First step in evaluating Red Lake’s air emissions for

future management needs and baseline information

– No local monitoring data

EI Process1) Training – Also available: ITEP’s online TEISS tutorialhttp://www4.nau.edu/itep/air/aq_wbteiss.asp

2) Obtain tools– TEISS, GIS

3) Determine objectives4) Inventory Preparation Plan (IPP)5) Identify sources6) Gather and input data into TEISS7) Peer review8) Submit to NEI & Report

Red Lake’s Objectives

1. Evaluate Red Lake’s air emissions by identifying and quantifying air emissions with the Diminished Reservation boundaries

2. Identify point source air emissions within a 50 mile radius of the Diminished Reservation

Step: Identifying Sources• Types of sources to include

– point, nonpoint/area, mobile• TEISS Calculator List

– Look list to get an idea what could be included• Phonebook

– Local phonebook in digital format or online with search function• List from Tribal Secretary’s office of businesses with operating

license to do business on Reservation• Local Reservation paper – business section• Windshield survey with cold Minnesota winter

– Easily see exhaust • Other DNR staff• Other Reservation’s EIs for ideas

Finishing Steps• Peer Review by Angelique Luedeker, ITEP– Emailed:

• Compressed TEISS file• Excel spreadsheets used for emissions not calculated in TEISS and

other estimations• Narrative explanation of data sources and calculation methods

• Submit to NEI– Obtain login to review data in database

• Presenting Results– Narrative Report– Display results via maps, charts, tables and graphs– Keep it simple and know your audience
