 STANDARD GUIDANCE MATRIX:
  • Greater than 5000 ft mixing height:   No burning within 5 miles of
    downwind SSRA. Maximum 100 tons per mile from downwind SSRA.
    Example: 500 ton maximum allowed if burned 5 miles from downwind SSRA.

  • 3000 - 5000 ft mixing height:   No burning within 10 miles of
    downwind SSRA. Maximum 75 tons per mile from downwind SSRA.
    Example: 750 ton maximum allowed if burned 10 miles from downwind SSRA.

  • Less than 3000 ft mixing height:   No burning within 15 miles of
    downwind SSRA. Maximum 50 tons per mile from downwind SSRA.
    Example: 750 ton maximum allowed if burned 15 miles from downwind SSRA.

  • All exceptions must be coordinated with the duty forecaster
    prior to ignition.
