During remodeling activities, resurface or seal the ' <br /> asphalt area to eliminate possible routes or� f / <br /> | <br /> contaminant migration into the soil . <br /> &- <br /> -- <br />' 2. Excavate, remove ind dispose of the waste oil tank <br /> � in accordance with existing regulations. <br /> -- <br /> ` | <br /> � <br /> � 3. Closure of the site investigation. <br /> �~ <br /> �It is evident from the extensive site investigation � <br /> K^ conducted by ETS that the limited contamination encountered <br /> _- � . <br /> poses no serious threat to human health or the environment. <br />� As far is the underground fuel tanks, product pipelines, and <br /> | pumping%stems are concerned, it is the opinion of ETS that | <br /> ' <br /> no further investigation is warranted. <br /> ' - � <br /> In7situ remediation of the soil beneath the waste oil i <br /> tank would not be cost effective. The location of the waste | <br /> oil tank, next to the building foundation� and under a natural | <br /> gas line, will make excavation difficult. It is recommended ' <br /> that prior to the removal of the tank, that it be exposed by ! <br /> - excavation. if removal of the tank is not possible, then in--- <br /> situ <br /> n-situ r0oediation will be further evaluated. <br /> � <br /> 1 <br /> - ' <br />
