The
Santa Cruz Harbor, operated by the Santa Cruz Port District, is located within
the Monterey Bay National Marine Sanctuary. Sediment has been dredged from
the harbor since 1964 in order to maintain its safety and navigability. RRM
was contracted to provide the Santa Cruz Port District with technical expertise
in the areas of sampling, evaluation, and characterization of sediments that
are dredged from the harbor and discharged into sanctuary waters.
RRM has designed and implemented sediment sampling protocols in the Santa
Cruz Harbor on an annual basis since 1998. A complex regime of physical and
chemical analyses and biological testing are required in order to obtain
final regulatory approval for theoffshore discharge of these sediments. Regulatory
guidelines for the sampling and analysis of dredge sediments have been developed
by
the
Dredge Material Management Office (DMMO), which consists of input from many
regulatory agencies including the United States Environmental Protection
Agency, the United States Army Corps of Engineers, and the Regional Water
Quality Control Board. Additional stakeholders that provide review and approval
of the Sampling and Analysis Plans and the Sediment Physical, Chemical and
Biological Evaluations for the dredging operations include the Department
of Fish and Game, the National Marine Fisheries Service, the California Coastal
Commission, and the Monterey Bay National Marine Sanctuary.
RRM works closely with Santa Cruz Port District personnel to plan and implement annual dredging operations. These dredge planning activities include:
