<div>3. BURNING INSTRUCTIONS FOR NORTHEAST OREGON ZONES 630-638</div>
<div> The following considerations should be adhered to in addition to</div>
<div> the requirements of the Oregon Smoke Management Plan. These</div>
<div> Instructions are valid for burning conducted on Saturday, April 25, 2009.</div>
<div> ==================================================================</div>
<div> </div>
<div style="padding-left: 36pt; ">Avoid ignitions within 10 miles to the W through NNW of SSRAs. Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. No additional restrictions necessary. </div>
