                      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!

    RANGE PORTION OF ZONE 624

    - Valid for burning done Friday, June 26, 2026.

==================================================================

 

Follow standard guidance matrix - see section 5 below - for burning units to the SW through WNW of SSRAs.  For units that will smolder significantly through the night avoid burning within at least 5 miles to the SW through NW in or near drainages leading to SSRAs.  No additional restrictions necessary. 

 

==============================================================

4.  SPECIAL NOTE:

 

    The smoke management forecaster is available at (503)

    945-7401.  The smoke management forecaster is available

    to discuss specific burns.  The duty forecaster phone

    number is (503) 945-7401. Please call this number and

    not individual's numbers to discuss daily burning. Please

    avoid calling between 1:30 to 2:45 p.m.

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.
