Shaw Environmental, Inc. 1 of 39<br />
The screening results and <strong>the</strong><br />
establishment of a correlation with<br />
confirmatory samples should be<br />
provided in an Appendix.<br />
Response<br />
Shaw will revise <strong>the</strong> first sentence in<br />
Section 3.5.4 to state <strong>the</strong> following:<br />
“On-site field screening was<br />

Shaw will revise Section 3.5.4 to<br />
include fur<strong>the</strong>r discussion of <strong>the</strong><br />
correlation between field screen and<br />
laboratory results <strong>for</strong> PCBs,<br />
explosives and metals. Since metals<br />
represented <strong>the</strong> majority of <strong>the</strong><br />
COCs at LLs 1-4, a table showing<br />
<strong>the</strong> XRF correlation results <strong>for</strong> <strong>the</strong><br />
pre-construction samples will be<br />
added to this section. Shaw will<br />
provide <strong>the</strong> text <strong>for</strong> review prior to<br />
issue of <strong>the</strong> Draft report.<br />
Include in section. Section 2.1.1 will be inserted into<br />
Section 2.0 and will state <strong>the</strong><br />
following: “Clean-up goals are <strong>the</strong><br />
maximum allowable concentrations<br />
which are protective of human<br />
health and <strong>the</strong> environment. Cleanup<br />
goals <strong>for</strong> surface and subsurface<br />
