3 SECTION 35 20 23, DREDGING 3.2.6.1

Overflow, Spillage and Leakage, state the following:

Scow overflow is allowed only during dredging operations while scow is being filled to its allowable capacity. Spillage and leakage of any and all dredge material or water is prohibited outside of areas specifically authorized for dredging in accordance with the project plans, specifications and permits. Any material that is spilled, escapes, leaks, sloughs, or is lost or misplaced outside of Dredged Material Management site(s) at any time during operations, to include but not limited to dredging, loading or transporting, shall be retrieved and deposited in accordance with the project plans, specifications and permits.

Based on the permits provided, it appears that decanting is only allowed if there is an approved monitoring plan that has been approved by the RWQCB. It is our understanding that a decanting monitoring plan may have prepared by the USACE and submitted to the RWQCB for review. It is requested that the monitoring plan be provided to the Contractor to be sure that all costs associated with the monitoring can be estimated prior to bid time, unless the USACE is providing all services associated with monitoring.

See Amendment coming soon.
