Criteria for evaluating proper disposal <br /> options should include amount of environmental/human impact as well as cost <br /> effectiveness. <br /> A suggested disposal option for the contaminated stockpiled soil (soil pile #3) <br /> could be grading fill for agricultural lands. The soil placed in this manner would <br /> provide low environmental impact and would be very cost effective with only <br /> transportation and grading costs involved. Any remaining hydrocarbons would <br /> be quickly biodegraded by the aerobic conditions associated with the shallow <br /> horizon of tilled agricultural soil. <br /> A second option for the soil disposal (soil pile #3) would include incorporating <br /> the soil into road base material for use as the compacted fill directly beneath the <br /> asphaltic concrete road surface. This disposal method provides a very low <br /> environmental impact with nominal costs. Any remaining hydrocarbons would <br /> be safely encapsulated beneath the asphalt covering of the roadway. <br /> If you should have any questions regarding this project, please contact the office. <br /> Respectfully Submitted, <br /> GEOLOGICAL TECENICS INC <br /> rVV�� <br /> Timoth .
