We Need Your Feedback!
The Smoke
Management Department is planning to “upgrade” this product so that it more
effectively meets your needs. To assist
us with this project, we are requesting feedback from you!
Below are a few
questions to help you consider what changes would be most beneficial for
you. All ideas are welcome!
Is the “Short-Term
Discussion” useful? What would enhance
it?
Is the “Long-term
Discussion” useful? What would enhance
it?
How could the
“Dispersion” forecast better meet your needs?
Is the “Outlook”
useful? What would enhance it?
Are the “Burning
Instructions” clear and concise? How
could they be improved for your use?
How do you access
the forecast product (i.e., Email; web page; telephone recording)?
We are considering
discontinuing or upgrading the phone recording of the forecast product. Is that something you currently use? Would you use it if you could get your
specific forecast from it faster?
Please Email your
feedback to: Peter.GJ.Parsons@odf.oregon.gov
Thank you!

5. 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.
* 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.
6. 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.
