Staff initially <br /> conducted an on-site inspection of the burning tine pit and visited individual <br /> residences closest to the fire. CD staff also surveyed an adjacent asphaltlaggregate <br /> plant,and nearby neighborhoods for smoke and odors. During these surveys,CD <br /> staff had the opportunity to speak with some of the residents and workers in this area. <br /> The majority of those contacted were disappointed that the fire has continued to burn <br /> into a third week- However, most said that the smoke plume had not cause any <br /> extraordinary problem for them This is mostly due to very favorable weather <br /> conditions (wind direction and smoke plume rise) which is carrying the smoke up and <br /> in a south/southeast <br /> direction away from the <br /> individual nearby <br /> residences and other <br /> more populated Tracy <br /> neighborhoods. <br /> At approximately a: <br /> 4. <br /> 3:50 a.m.on August 25, <br /> staff resumed surveying <br /> the areas around the <br /> Tracy tire fire.

Dorm tie <br /> early morning hours (4-6 a.m.), staff observed the smoke plume going in a <br /> west/northwest direction. Although five smoke plume was no longer rising as much or <br /> as fast as during the day,it was not touching the ground. 'There are approximately six <br /> or seven medium size industrial facilities scattered throughout this area northwest of <br /> the fire. However,it does not appear that they are being significantly impacted. <br /> Tracy neighborhoods in the southwest part of the city are also not being affected,as <br /> they are located further north of smoke plume's path_ At 6 a.m.the plume was <br /> observed to rise more rapidly and change to a westerly direction. CD staff had noted <br /> these same general changes in plume direction three weeks ago during the initial <br /> emergency response to this incident. It appears that during a typical 24-hour day, the <br />
