<br /> January 25, 2011
<br /> The soil samples were submitted for the following analyses:
<br /> • TPHg and TPHd by EPA method 8015M; and
<br /> • BTEX and MTBE by EPA method 8260B
<br /> Analytical results are summarized below and in Table 4. The laboratory analytical report is
<br /> included in Attachments A-4. j
<br /> TPHg and MTBE were not reported above laboratory reporting limits in any sidewall sample.
