Spongeplant Control Program
Document Type
EIR - Draft EIR
Document Description
The objective of the SCP is to keep waterways safe and navigable by controlling the growth and spread of spongeplant (Limnobium laevigatum) (referred to as spongeplant) in the Sacramento-San Joaquin Delta (Delta), its surrounding tributaries, and Suisun Marsh. Spongeplant is not yet well established in the Delta. Thus, the goals of the SCP will be to keep the spongeplant infestation at a low level and limit the spread of spongeplant in the Delta. The SCP balances potential impacts of spongeplant management while (1) minimizing non-target species impacts and (2) preventing environmental degradation in Delta waterways and tributaries. The SCP will operate under the following three permits/guiding documents: - National Pollution Discharge Elimination System (NPDES) Statewide General Permit (CAG990005) - A United States Fish and Wildlife Service (USFWS) Biological Opinion (currently in the consultation process) - A National Oceanic and Atmospheric Administration - National Marine Fisheries Service (NMFS) Letter of Concurrence (currently in the consultation process).
