A-66 Table B-4 Why are <strong>the</strong>re so many “NA”s on <strong>the</strong><br />
tables? Please clarify.<br />
A-67 Appendices (General) Change <strong>the</strong> cover pages, title and spine to<br />
match <strong>the</strong> title of <strong>the</strong> main text of <strong>the</strong><br />
report.<br />
A-68 Please send a copy of <strong>the</strong> bills of lading<br />
and manifests to my office so I can have a<br />
quick look at <strong>the</strong>m. If I cannot review <strong>the</strong>m<br />
by <strong>the</strong> 30JUN08 deadline; this will not<br />
have any impact on project approval.<br />
A-69 Verification needed. 100% of <strong>the</strong> data was<br />
verified. Was a minimum of 10% of <strong>the</strong><br />
data validated by an independent third<br />
party? Please clarify.<br />
A-70 Thanks <strong>for</strong> sending along <strong>the</strong> field logs. I<br />
will look at <strong>the</strong>m as soon as possible.<br />
A-71 Please make sure waybills are included in<br />
<strong>the</strong> official project file to complete <strong>the</strong><br />
chain of custody.<br />
A-72 Clarify <strong>the</strong> lack of MS/MSD samples <strong>for</strong> a<br />
number of sample groups.<br />

Response<br />
<strong>for</strong> VOCs.<br />
The NAs <strong>for</strong> certain chemicals<br />
indicates <strong>the</strong> sample was not<br />
analyzed <strong>for</strong> that particular chemical<br />
in that sample. There are a large<br />
number of NAs on <strong>the</strong> table because<br />
an expanded analyte list was used<br />
<strong>for</strong> <strong>the</strong> same method (8260B and<br />
8270C) on <strong>the</strong> second set of<br />
samples as compared to <strong>the</strong> first.<br />
The extended lists were not<br />
requested by Shaw and were run by<br />
<strong>the</strong> laboratory by mistake.<br />
Regardless of <strong>the</strong> list, no VOC and<br />
SVOC impact above allowable<br />
backfill thresholds were detected.<br />
The title will be changed to match<br />
<strong>the</strong> Cover and Title page. See<br />
Comment A-2.<br />
Copies of <strong>the</strong> BOLs and Manifests<br />
will be <strong>for</strong>warded during week of 22<br />
June 2008.<br />
Shaw validated 100% of <strong>the</strong><br />
received data <strong>for</strong> samples collected<br />
during <strong>the</strong> work prior to inclusion <strong>for</strong><br />
accuracy. Shaw did not have data<br />
validated by an independent third<br />
party.<br />
Your welcome and thanks <strong>for</strong> your<br />
prompt attention.<br />
Comment noted – we will retain<br />
waybills and include in files on future<br />
work.<br />
Shaw collected MS/MSD samples at<br />
a minimum frequency of 5% (1 per<br />
20 samples) <strong>for</strong> all sample groups as<br />
