Good afternoon Leigh,

Attached is the revised work plan for the Reading Truck Site with the updates that you requested. To assist you with your
review, please refer to Section 3.2 on page 6 for the excerpt we added regarding the hexavalent chromium sensitivity, and
Section 5.0 on page 8 for the reference to sampling for arsenic and addressing the background threshold value. Please let
us know if you any further questions or concerns about the work plan before providing your approval.

Thank you,

Expertise. Innovation.
Commitment. Nationwide.

Hey Steve, I see the changes. I like the hex chrome change, it looks similar to how PCBs are called out under the soil
section, and it makes sense to call out the hexchrome under the groundwater section.
The arsenic change has the levels that will be compared called out in the bullet points on page 8 above it, however we
would like MCLs to be listed in the bullet point about what we will be screening against. MCLs show up for some of
the UGWPS but not all of them. You have elsewhere in the document that you will be using RSLs and MCLs, if you can
give us this change in those bullet points so this is consistent and what you discussed with Bill about using RSLs and
MCLs then we could accept.

Please note that the other options listed, like the RSLs and VISLs are numbers we use regularly in the program, but we
also use MCLs and would like this called out.

Hi Leigh,

Thanks again for giving me a call. I have added in MCLs to the intended screening levels under section 5.0
as you requested. The updated work plan is attached. As you mentioned, with the addition of the MCLs to
the text, we will consider this work plan approved and move forward with sampling tomorrow.
