The primary driver of the schedule change, as described in the attached memo, is a requirement for the applicant's contractor to recollect and test 3 additional sediment samples, as the original samples exceeded the holding times specified in the Corps/EPA/Approved sediment analysis plan and the Corps/EPAs 2003 Regional Implementation Agreement and cannot be considered scientifically sound. The memo also describes an additional risk to schedule associated with proposed sediment deposition sites behind Corps Levees parallel to the federal navigation channel.
