Review Notes :
Document is the AECOM addendum dated December 2020 (cover page). A VDEQ letter of acknowledgment dated 2022-03-31 is included in the PDF but the addendum itself is dated 2020-12. I selected category 'South River Remediation Documents' and type 'Work Plan' because this is a technical execution plan/addendum describing remedial excavation; 'Work Plan' best reflects the implementation focus.
