The applicant proposes
to dredge Barge No. 5 berth, slip #2, and the inside basin southwest
of slip #1, at St. George Ferry Terminal. The St. George Ferry Terminal is located in
Richmond County, NY at the northern tip of Staten Island, and is a major intermodal
transportation center occupying approximately seven acres bordering New York Harbor.
New York City Department of Transportation operates the Staten Island Ferry, connecting
Staten Island and Manhattan, from this facility. The ferry terminal is currently undergoing
substantial rehabilitation with an anticipated completion by August 2003. The facility will be
fully active during the rehabilitation.
Based on a February
2001 bathymetric survey 10,495 cubic yards of material is expected to
be removed over an area of about 34,780 square feet.
- Barge #5 Berth: Approximately 8,125 cubic yards of material is to be dredged
from an area 100' by 230' to a depth of 17 ' below mean low water (MLW).
- Slip #2: Approximately 2165 cys of material would be dredged from an area 100'
by 230' to a depth of 9' below MLW, except for the entrance to the slip which
will be dredged to 15' below MLW to accommodate tug boats.
- Inside Basin: The basin will be cleared of debris after which approximately 205
cys of material will be dredged from a 5,000 square foot area to a depth of 4'
below MLW.
Test data reveal that
the dredging of Barge No. 5 Berth and Slip 2 would expose
contaminated sediments, therefore clean sand will be placed atop the dredged areas as
capping material. Sand capping of these areas is consistent with the recommendations
published in the US EPA 1994 ARCS Remediation Guidance Document. The source of the
contamination has yet to be determined. The Applicant is working closely with the NYS
Department of Environmental Conservation to identify the source.
Special conditions
will be placed on the dredging operation, including but not necessarily
limited to:
- the use of an environmental bucket,
- the deployment of a hard boom around the perimeter of the dredge site,
- the hard boom is to be lined with a soft boom,
- a silt curtain is to be placed inside of the booms,
- absorbent rolls and sweeps will be on hand for clean-up of any slicks or sheens.
