Exhibit 4-10, cont.
Example Observations and Lessons Learned (Section 9)
♦
The relatively mild year-round temperatures at the site provided a beneficial growing environment for the
inoculum of PAH-degrading microorganisms. Consequently, relatively high numbers of microorganisms
remained in the soil, thus reducing the need for repeated soil inoculations.
♦
Soils at the site were difficult to till after heavy rains. Natural drying of the soil took an average of two weeks
before tractors could be operated on the land treatment area.
♦
Nuisance odors were reported on days when soils were tilled. Therefore, measures were taken to till on days
when the wind direction was away from neighboring properties.
