 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 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.
