NOTICE OF APPLICABILITY - 2 - 30 July 1999 U.S. ARMY COE AND PORT OF STOCKTON SAN JOAQUIN, SACRAMENTO, AND CONTRA COSTA COUNTIES these submittals, it appears that the proposed channel maintenance dredging activities should meet the applicability requirements of General Order No. 96-220. However, because the actual site specific Plans were not included with the NOI as is required in Attachment B and Provision F.3 of the General Order, we can only issue this conditional NOA. Additionally, the Monitoring and Reporting Program No. 96-220 prescribes the minimum monitoring requirements that must be performed during the dredging and dredged material disposal site activities to demonstrate compliance with the General Order. PROJECT LOCATION The deep water ship channel maintenance dredging activities will be performed within the channel reaches at river miles 5.45 to 6.17; 10.91 to 11.29; 15.42 to 16.17; 35.04 to 38.03; and 38.56 to 39.17 in the San Joaquin River, as shown in Attachment 1, which is attached and part of this Notice by reference. PROJECT DESCRIPTION The Sacramento District of COE will perform maintenance dredging along the Stockton Deep Water Ship Channel for the Port of Stockton. The maintenance dredging project will remove up to 634,699 cubic yards of sediment that has settled into parts of the shipping channel along the San Joaquin River. To demonstrate that the anticipated dredged material is `Inert Waste', as defined in Title 27, Chapter 3, Section 20230 of the California Code of Regulations (CCR), the COE sampled and analyzed sediments at various locations along the channel reaches where the shoal dredging will occur. The predredged sediment samples met the applicability limits listed in A.3 of Order No. 96-220. The dredger is expected to operate 24 hours a day, 7 days a week. Based upon an average daily rate of 6,500 cubic yards, the dredging can be completed in 98 days with the anticipated completion date of on or near 31 December 1999. Dredging activity will likely restart in early March 2000 if the 31 December 1999 deadline is not achieved. The Stockton Deep Water Channel bottom width ranges between 200 to 400 feet. The thickness of the proposed dredging at the bottom of the channel is between 2 to 4.5 feet. Roberts Island I and H, S-4, and Bradford Island DMD sites are owned and maintained by the Port of Stockton. The McCormick Pit, Scour Pond, and Augusto Pit located on Sherman Island are owned and maintained by the California Department of Water Resources. Because the proposed dredged sediments have been demonstrated to meet the `Inert Waste' classification as defined in Title 27, Chapter 3, Section 20230 of the CCR, no significant threat to ground or surface water exists by placing the sediment at sites identified above. If the dredged sediment decanting procedures are followed as outlined in the Operational Plan identified in the NOI, then no impact should occur to surface water from the dredged sediment return water. The dredged sediments will likely be used for levee maintenance and construction projects.
