In response to a request from EPA Region 4, NOAA Fisheries has prepared a biological opinion on EPA’s proposal to approve diazinon, nonylphenol, and selenium water quality criteria for the state of Georgia.
These guidelines are intended to help solve problems with longitudinal connectivity for effective fish passage at road-stream crossings and other infrastructure that cross streams.
This opinion considers the effects of removing the existing bridge and abutments, land-based blasting, in-water pile driving of steel piles, excavation and placement of fill and armor rock, construction vessel traffic, and support operations.
