ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 228
[FRL-7077-1]
Ocean Dumping; Proposed Site Modification
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA today proposes to modify the designation of an Ocean
Dredged Material Disposal Site (ODMDS) in the Atlantic Ocean offshore
Charleston, South Carolina. The proposed modification is to modify the
restriction on use and shorten the site's name. This proposed action is
necessary to allow for disposal activities to continue as previously
planned by the site's Task Force for management and monitoring.
DATES: Comments must be received on or before November 26, 2001.
ADDRESSES: Send comments to: Wesley B. Crum, Chief, Coastal Section,
Water Management Division, U.S. Environmental Protection Agency, Region
4, 61 Forsyth Street, Atlanta, Georgia 30303.
FOR FURTHER INFORMATION CONTACT: Gary W. Collins, 404/562-9395.
SUPPLEMENTARY INFORMATION:
A. Background
Section 102(c) of the Marine Protection, Research, and Sanctuaries
Act (MPRSA) of 1972, as amended, 33 U.S.C. 1401 et seq., gives the
Administrator of EPA the authority to designate sites where ocean
disposal may be permitted. On December 23, 1986, the Administrator
delegated the authority to the Regional Administrator of the Region in
which sites are located. The EPA Ocean Dumping Regulations promulgated
under MPRSA (40 CFR chapter I, subchapter H, Sec. 228.11) state that
use of disposal sites may be modified.
Two ODMDS's were ultimately designated for Charleston in 1987. One
was a 12-square mile site for deepening material. The second site was
3-square miles and was placed within the 12-square mile site. During
the 1980's, additional benthic and sedimentological studies were
conducted by South Carolina Department of Natural Resources (SCDNR). In
1987, live bottoms were identified in the western portion of the 12-
square mile site. Concerns regarding impacts to the living resources at
the ODMDS encouraged EPA to place a restriction on the use of the 12-
square mile site. The Final Rule regarding this restriction was
published in the Federal Register March 5, 1991 stating, ``Disposal
shall be limited to dredged material from the Charleston Harbor area.
All dredged material, except entrance channel material, shall be
limited to that part of the site east of the line between coordinates
32 deg.39'04" N, 79 deg.44'25" W and 32 deg.37'24" N, 79 deg.45'30" W
unless the materials can be shown by sufficient testing to contain 10%
or less of fine material (grain size of less than 0.074mm) by weight
and shown to be suitable for ocean disposal.'' This bisecting line was
an immediate effort by EPA to protect live bottom resources initially
reported by fishermen. The line was set with limited knowledge of the
exact location and extent of those resources, and was set in a location
that was believed to be as protective as possible at that time.
During this same time frame, an interagency group (EPA, DNR, COE
and State Ports Authority) began working together to develop a
monitoring and management plan (MMP) for the ODMDS. As part of this MMP
process, construction of an L-shaped berm was developed approximately
midway within the ODMDS. The COE began construction of the L-shaped
berm using consolidated material from the last (42-foot) deepening
project. The berm was evident on 1993 bathymetry. Also, as part of the
MMP, the interagency group began looking for an area within the ODMDS
for disposal of dredged material which would have the least impacts on
the live bottom resources located in the western region of the site. A
4-square mile area (disposal box) was identified within the eastern
half of the 12-square mile designated ODMDS and placed in position with
the L-shaped berm as part of the western boundary. This location was
approved by all the agencies involved, and placed where it would impact
minimal reef habitat. At that time, the bisecting line should have been
moved, but due to an oversight, it was not.
In 1995, EPA de-designated the smaller 3-square mile site and
modified the larger site to allow for continued disposal of all
material, not just deepening material. However, the COE agreed not to
place any material outside of the 4-square mile disposal box. During
the 1999-2000 (deepening project) dredging, a number of unauthorized
dumps occurred to the west of the 4-square mile site. To date, studies
indicate that some fine-grained material is present to the west of the
4-square mile site. It is unknown at this time whether the disposal
material is moving from the ODMDS over the berms, from the berms, is
part of the unauthorized dumps that occurred in 1999 and 2000, whether
it is from the dispersion of the material during disposal activities at
the site, or whether it is some combination of these four
possibilities. Subsequent investigation and studies conducted by SCDNR
to date have not identified adverse impacts at index reef sites being
monitored. Other samples of the sand bottom benthic communities in
areas that now have muddy sediments are still being processed.

B. EIS Determination
EPA has voluntarily committed to prepare Environmental Impact
Statements (EIS) in connection with the designation of ocean disposal
sites (39 FR 16186 (May 7, 1974)). The need for an EIS in the case of
modifications is addressed in 39 FR 37420 (October 21, 1974), section
1(a)(4). If the change is judged sufficiently substantial by the
responsible official, an EIS is needed.
The continued use of the Charleston ODMDS is vital to the
management goals of the Plan. EPA believes these changes do not warrant
the preparation of an Environmental Impact Statement (EIS).
EPA's primary concern is to provide an environmentally acceptable
ocean disposal site for Charleston Harbor area dredging projects on a
continued basis.
C. Proposed Site Modification
The proposed site modification for the Charleston Harbor Deepening
Project ODMDS is the removal of the line that restricts disposal of
fine-grained material and the addition of four corner coordinates (4
square-mile disposal box) that will define where all dredged material
must be placed within the ODMDS. In addition, the site's official name
is being shortened to the Charleston ODMDS.
D. Regulatory Assessments
Under the Regulatory Flexibility Act, EPA is required to perform a
Regulatory Flexibility Analysis for all rules that may have a
significant impact on a substantial number of small entities. EPA has
determined that this proposed action will not have a significant impact
on small entities since the modification will only have the effect of
providing an environmentally acceptable disposal option for dredged
material on a continued basis. Consequently, this Rule does not
necessitate preparation of a Regulatory Flexibility Analysis.
Under Executive Order 12291, EPA must judge whether a regulation is
``major'' and therefore subject to the requirement of a Regulatory
Impact Analysis. This proposed action will not result in an annual
effect on the economy of $100 million or more or cause any of the other
effects which would result in its being classified by the Executive
Order as a ``major'' rule. Consequently, this Rule does not necessitate
preparation of a Regulatory Impact Analysis.
This Proposed Rule does not contain any information collection
requirements subject to Office of Management and Budget review under
the Paperwork Reduction Act of 1980, 44 U.S.C. 3501 et seq.
