Odors that were moderate to strong near the working face were reduced to mild,very faint, or non-detectable at locations surveyed on Austin Road. On the days surveyed [assumed to be typical operations] the water trucks were seen controlling onsite dust generation by periodically watering the on-site landfill roads and areas used by trucks near the working face. Track-out of dirt onto Austin Road near the entrances to the Forward Recovery Center(Location 2) and Forward Landfill (Location 3)are the source of re-entrained road dust on Austin Road observed during the surveys. Mitigation Measure D.1.would reduce the level of re-entrained dust to a less-than-significant level. Potentially significant odor impacts would be reduced to a less-than-significant level by implementation of Mitigation Measure D.3,below. r r
