PHASE I E S A Aamco Transmissions 9330 S. Halsted Street Chicago, IL 60620

Findings & Recommendations As a result of our Phase I of the subject property, AES has identified the following sources of potential environmental concern (i.e. recognized environmental conditions) that warrant further discussion: UST Systems There is an out-of-service used-oil UST system located off the south side of the garage building and an abandoned gasoline UST system possibly located off the southeast corner of the building that have potential to have leaked and caused subsurface contamination. Regardless, both UST systems are currently viewed as non-regulated UST systems by CDOE and their removal and/or proper abandonment is not required under current regulations unless either is found to be posing an imminent threat to human health or the environment. Hydraulic Car Lifts There are five hydraulic car lifts possibly abandoned beneath the shop area of the garage building that have potential to have leaked and caused subsurface contamination. Regardless, the lifts are non-regulated and the removal and/or proper abandonment of said is not required under current regulations. Subsurface Contamination There is indeed potential for subsurface contamination to exist at the subject property caused by UST systems, hydraulic car lifts, and the longtime usage of hazardous materials and petroleum products at the site. Regardless, risk-based factors suggest that any contamination would be highly unlikely to be posing any imminent threat to human health or the environment and that further investigation and/or remediation of said would not be required as long as the site is not redeveloped or modified through excavation. Furthermore, any future attempt by other consultants in recommending that a No Further Remediation (NFR) Letter be obtained through the Site Remediation Program (SRP) or that further investigation be conducted to examine potential impacts from the surrounding dry cleaners should only be viewed as an attempt at obtaining needless additional work.
