<div>3. BURNING INSTRUCTIONS FOR ZONES 624 AND 625 INCLUDING THE WALKER</div>
<div> RANGE PORTION OF ZONE 624</div>
<div style="padding-left: 36pt; ">This instruction is valid for burning conducted on Wednesday, December 16, 2009.</div>
<div style="padding-left: 36pt; ">==================================================================</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Unfavorable burning situation due to very poor smoke dispersion. Delay ignitions until 11:00am. Avoid ignitions within 20 miles to the SW through WSW of SSRAs. For units that will smolder significantly through the night
avoid burning within at least 35 miles to the SSW through WSW in or near drainages leading to SSRAs. Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. Recommend against burning units that will smolder significantly
overnight. Complete ignitions by 3:00pm. </div>
