Title

Program Environmental Impact Report for Humboldt Bay Sediment Management

Description

This Draft PEIR assesses the potential environmental effects of implementing the Humboldt Bay Sediment Management Program. This PEIR explores four alternatives and provides an environmental analysis of dredging methods, sediment processing, and sediment placement at beneficial use sites that will guide implementation of the Coastal Regional Sediment Management Plan for the Eureka Littoral Cell and steer sediment management for Locally Maintained Sites (LMS). The Project is located in Humboldt Bay and consists of 25 sites where dredging may occur, three sites where sediment may be dewatered and temporarily stockpiled and 76 sites where sediment may be beneficially used. Under Alternative 1 the method of sediment removal at LMSs would be suction dredging only and Alternative 2 considers only using clamshell bucket dredging for sediment removal. Under Alternative 3 the method of dredging may be either via suction or clamshell bucket dredging. In this scenario, dewatering and stockpiling of sediments at upland locations for future transport to a beneficial use site would not be conducted. Sediment would be piped directly to beneficial use sites, under this Alternative. The No-Project Alternative assumes that LMSs would continue to be dredged by their respective responsible entities, but there would be no comprehensive plan for dredging LMSs in Humboldt Bay. Dredged sediments would likely continue to be disposed of at the HOODS rather than used for beneficial projects around the bay.
