NOTICE OF APPLICABh-i FY -2- 12 September 1995 U.S. ARMY CORPS OF ENGINEERS PORT OF STOCKTON Regulations (CCR), the COE sampled and analyzed sediments at various locations along the channel reaches where the shoal dredging will occur. The anticipated average daily dredging rate will be 7200 cubic yards and the project will take approximately 21 days to complete. The two DMD sites on Sherman Island are owned by the State of California and operated by the Department of Water Resources for stockpiling levee maintenance materials. The Bradford Island DMD site is privately owned and is also used for stockpiling levee maintenance materials. Because the proposed dredged sediments have been demonstrated to meet the 'Inert Waste' classification as defined in Title 23, Chapter 15, Section 2524 of the CCR, no significant threat to ground or surface water exists by placing the sediments at any of the three sites identified above. If the dredge sediment decanting procedures are followed as outlined in the Operations Plan identified in the ROWD,then no impact should occur to surface waters from the decanted dredged sediment return water. OPERATIONS PLAN The Operations Plan included with the ROWD states that the dredged sediments and water will be pumped or transported from the dredger to the dredged material disposal sites. Dredge materials will be allowed to settle for a minimum settling/detention time in order to ensure the decant waters do not exceed a maximum total suspended solids concentration. The minimum detention time and maximum total suspended solid concentrations identified in the DMD Operations Plan for each site that must be adhered to before the dredge decant waters are allowed to return to the San Joaquin River are as follows: DMD Site Location Minimum Detention Time Maximum TSS Sherman Island - McCormick Pit 21 hours 290 mg/1 Sherman Island - Pond Site 21 hours 290 mg/1 Bradford Island Site 36 hours 200 mg/1 Monitoring of the dredging operations and at the dredge disposal site will be performed by the COE's contractor, according to the General Order and the approved Operations Plan. GENERAL INFORMATION 1. The project shall be constructed and operated in accordance with the requirements contained in the General Order and in accordance with the information submitted in the report of waste discharge. 2. Regional Board staff shall be notified at least 24 hours prior to the start of project construction activities. 3. An annual fee may be assessed against this project until a Notice of Termination has been received that this project is complete. 4. Discharge of material other than `inert waste' dredged sediment from the Stockton Deep Water Ship Channel Maintenance Project to the dredge material disposal sites shown on Attachment 1 is prohibited. 5. Failure to abide by the conditions of the General Order and the approved Operations Plan could result in an enforcement action as authorized by provisions of the California Water Code.
