3. STANDARD GUIDANCE MATRIX:

 

* Greater than 5000 ft mixing height: Limit to 150 tons per mile

from downwind SSRAs. Example: 75 tons allowed if burned a half

mile from a downwind SSRA.

 

* 3000 - 5000 ft mixing height: Limit to 50 tons per mile if burning

within 5 miles of downwind SSRAs. Limit to 100 tons per mile if

burning 5 miles or beyond downwind SSRAs.

Example #1: 200 tons allowed if burned 4 miles from a downwind SSRA.

Example #2: 500 tons allowed if burned 5 miles from a downwind SSRA.

 

* Less than 3000 ft mixing height: No burning within 5 miles of

downwind SSRAs. Limit to 60 tons per mile from downwind SSRAs.

Example: 300 tons allowed if burned 5 miles from a downwind SSRA.

 

* Ensure adequate spacing between units when burning near downwind

SSRAs.

 

* Use of polyethylene (PE) sheeting on greater than 75 percent of

piles in a unit with 60 percent coverage per pile will allow a

50 percent increase in tonnage over the existing instruction tonnage

for that zone.

 

* All exceptions must be coordinated with the duty forecaster

prior to ignition.

 

 

4. BURN MONITORING:

 

Burns over 2000 tons must be monitored (OAR 629-048-0230(3) -

7/1/14). Monitoring of all burns is highly recommended for both

smoke management purposes and wildfire potential.
