Please remember to plan your burns this year during the spring and fall burn windows

Every year there are two open burning windows for residents to burn yard debris ie: leaves, branches weeds and such, this does not include garbage, tires, construction materials, cardboard and other trash.

There are several factors that regulate open burning in our County some apply only to residential burning and some apply to both agricultural and residential burning, they are listed below.

1. During the year the State Forester puts a ban on any open burning for those areas East of Highway 89 and Highway 38 on the entire Wasatch Front, this ban goes from June 1 to October 31

2. Clearing Index:

The Clearing Index is an Air Quality/Smoke Dispersal Index used to regulate open burning and as input for other air quality decisions throughout Utah. The Clearing Index is defined as the Mixing Depth (depth of the mixed layer in 100s of feet above ground level) multiplied by the Transport Wind (average wind in the mixed layer in knots). Clearing Index values below 500 are considered poor ventilation and open burning is restricted under these conditions. Any Clearing Index values above 1000 are considered excellent ventilation and are referred to as 1000+. Data for the Clearing Index on these web pages are derived from the Eta and AVN operational atmospheric computer models. The data will be reviewed and may be edited by NWS meteorologists before dissemination.

An example calculation of the Clearing Index for Salt Lake City:

Mixed Layer Depth = 10000 feet

Transport Wind = 8 knots

Clearing index = (10000/100 feet) X 8 knots = 800

Note: Clearing Index is 1000+ if measurable precipitation or cold front passage occurs.

3. Open burn periods set by the state for residential  March 30th to May 30th and September 15 through October 30th. Please Remember Sundays
