composites exceeded the guidance of 20 ppb. Of these nine fi sh composites, only
two, representing one species, spotted sand bass, were from a species considered to
be resident to Newport Bay. The remaining seven composites above 20 ppb were
from coastal species, i.e., those that migrate up and down the coast. Coastal species
could have received exposures from higher PCB levels outside of Newport Bay.
Even the spotted sand bass migrates off shore in the winter, creating the possibility
of exposure to PCBs outside of Newport Bay.

6.2 California Sport Fish Guidance to Protect Human Health

The SARWQCB ( 2006 ) report states that three resident species from upper Newport
Bay displayed residue levels in excess of the guidance, whereas the underlying data
cited in Appendix A-1 states that only one resident species, spotted sand bass, from
upper Newport Bay, was in excess of the guidance. Review of the cited studies
