  • Description:
    "The NOAA RC proposes to construct a partially submerged tidal barrier (sill) at the mouth ofthe Parsons Slough Channel. The purpose of the project is to reduce tidal scour in Parsons Slough and improve essential fish habitat for Coastal Pelagic and Pacific Coast Groundfish species. Construction of the sill requires vibratory and impact pile driving to install sheet pile and end-bearing piles into the seafloor. No impacts to ESA-listed marine mammals under NMFS' jurisdiction are expected to occur. However, non-ESA listed harbor seals may ... experience Level B harassment due to noise from pile driving activities. Impacts are expected to be short term and include avoidance, masking, and interruption of behavioral activities (e.g., resting) at time of exposure. The National Marine Fisheries Services (NMFS) proposes to issue an Incidental Harassment Authorization (IHA) to permit incidental take of small numbers of marine mammals pursuant to Section 101(a)(5)(D) ofthe Marine Mammal Protection Act (MMPA)"--Cover letter; Portfolio comprised of three related PDF documents digitized and organized by: NOAA Office of Program Planning and Integration (PPI) National Environmental Policy Act (NEPA) staff.
