Comment<br />
“…that it is electron capturing<br />
and…” Text here seems<br />
awkward. Consider revising.<br />
• Line 28: Change “disposal”<br />
to “disposable”.<br />
• Lines 28-31: Text states that<br />
<strong>the</strong> aliquots were placed into a<br />
clean plastic-lined bucket and<br />
combined to make a single<br />
sample. A max of 1 kg was<br />
<strong>the</strong>n removed and placed into a<br />
labeled pre-cleaned container.<br />
Is this allowed by ei<strong>the</strong>r <strong>the</strong><br />
Guidance <strong>for</strong> MI Sampling<br />
procedures, or <strong>the</strong> <strong>Final</strong><br />
RAWP? In my experience, this<br />
is not acceptable when doing<br />
MI sampling.<br />
• Line 33: States that 20<br />
aliquots were collected from<br />
smaller excavation areas. Is<br />
this allowed by <strong>the</strong> MI<br />
Sampling procedures, or<br />
Shaw’s <strong>Final</strong> RAWP? In my<br />
experience, 30 aliquots is <strong>the</strong><br />
minimum based on <strong>the</strong><br />
underlying statistical <strong>the</strong>ory.<br />
Recommend replacing “;” with<br />
“:” after <strong>the</strong> word “Shaw”.<br />

Recommendation<br />
Response<br />
This section has been revised<br />
extensively per comments received<br />
by from Kathy Krantz, in<br />
particularly comment A-1. Shaw<br />
will provide text <strong>for</strong> review prior to<br />
issuing <strong>the</strong> Draft report.<br />
• “disposal” will be changed to<br />
“disposable”.<br />
• Please see response to comment<br />
A-3 regarding sample weight<br />
submitted <strong>for</strong> MI processing. This<br />
methodology was agreed upon by<br />
USACE and OhioEPA prior to<br />
implementing field sampling<br />
activities.<br />
• This sampling methodology was<br />
requested by <strong>the</strong> Ohio EPA Facility<br />
Coordinator, Ms. Eileen Mohr in<br />
concurrence with <strong>the</strong> USACE COR,<br />
Mr. John Jent. Section 3.6.1 of <strong>the</strong><br />
RAWP specifies this sampling<br />
methodology.<br />
“;” will be replaced with “:” after <strong>the</strong><br />
word “Shaw”.<br />
Ms. Krantz’s chemistry comments<br />
have been addressed and <strong>the</strong>
