MAINTENANCE DREDGING IN ST. MARY PARISH
NAME OF APPLICANT: Morgan City Harbor and Terminal District, c/o: GIS Engineering, LLC, Attn: Brenton Jenkins, 450 Laurel Street, Suite 1500, Baton Rouge, Louisiana 70801
LOCATION OF WORK: Located in Atchafalaya River Lower Channel, stations 700+00 to 1355+00, in St. Mary Parish (29.323742, -91.426389), as shown within the attached drawings. (HUC: 08080101, Atchafalaya Watershed).
CHARACTER OF WORK: Maintenance dredging (by barge-mounted suction dredge, with side-cast of material overboard for dispersal into deeper, turbid waters) of the Atchafalaya Bar Channel from stations 700+00 to 1355+00 to maintain a 20-foot deep (plus 2 feet of advanced maintenance and 2 feet of allowable over-depth) by 400-wide navigational channel, all to improve navigation safety. Approximately 17,000,000 cubic yards would be dredged and subsequently dispersed encompassing an area of approximately 890 acres of open water. Permit implementation would impact no wetlands; therefore, compensatory mitigation was not proposed by the applicant.

MAINTENANCE DREDGING IN ST. MARY PARISH
NAME OF APPLICANT: Morgan City Harbor and Terminal District, c/o: GIS Engineering, LLC,
Attn: Brenton Jenkins, 450 Laurel Street, Suite 1500, Baton Rouge, Louisiana 70801
LOCATION OF WORK: Located in Atchafalaya River Lower Channel, stations 700+00 to
1355+00, in St. Mary Parish (29.323742, -91.426389), as shown within the attached drawings.
(HUC: 08080101, Atchafalaya Watershed).
CHARACTER OF WORK: Maintenance dredging (by barge-mounted suction dredge, with sidecast of material overboard for dispersal into deeper, turbid waters) of the Atchafalaya Bar Channel
from stations 700+00 to 1355+00 to maintain a 20-foot deep (plus 2 feet of advanced maintenance
and 2 feet of allowable over-depth) by 400-wide navigational channel, all to improve navigation
safety. Approximately 17,000,000 cubic yards would be dredged and subsequently dispersed
encompassing an area of approximately 890 acres of open water. Permit implementation would
impact no wetlands; therefore, compensatory mitigation was not proposed by the applicant.
The comment period for the Department of the Army Permit and the Louisiana
Department of Environmental Quality WQC will close 20 days from the date of this joint public
notice. Written comments, including suggestions for modifications or objections to the
proposed work, stating reasons thereof, are being solicited from anyone having interest in this
permit and/or this WQC request and must be submitted so as to be received before or by the
last day of the comment period. Letters concerning the Corps of Engineers permit application
must reference the applicant's name and the Permit Application Number, and be forwarded to
the Corps of Engineers at the address above, ATTENTION: REGULATORY BRANCH.
Individuals or parties may request an extension of time in which to comment on the proposed
work by writing, faxing, or e-mailing the Corps of Engineers Project Manager listed above. Any
request must be specific and substantively supportive of the requested extension, and received
by this office prior to the end of the initial comment period. The Section Chief will review the
request and the requestor will be promptly notified of the decision to grant or deny the request.
If granted, the time extension will be continuous to the initial comment period and, inclusive of
the initial comment period, will not exceed a total of 30 calendar days. Letters concerning the
Water Quality Certification must reference the applicant's name and the WQC Application
number and be mailed to the Louisiana Department of Environmental Quality at the address
above.
The application for this proposed project is on file with the Louisiana Department of
Environmental Quality and may be examined during weekdays between 8:00 a.m. and 4:30
p.m. Copies may be obtained upon payment of costs of reproduction.
Corps of Engineers Permit Criteria
The decision whether to issue a permit will be based on an evaluation of the probable
impacts, including cumulative impacts of the proposed activity on the public interest. That
decision will reflect the national concern for both protection and utilization of important
resources. The benefit which reasonably may be expected to accrue from the proposal must be
balanced against its reasonably foreseeable detriments. All factors which may be relevant to
the proposal will be considered including the cumulative effects thereof; among those are
conservation, economics, aesthetics, general environmental concerns, wetlands, historic
properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation,
shoreline erosion and accretion, recreation, water supply and conservation, water quality,
energy needs, safety, food and fiber production, mineral needs, considerations of property
ownership and, in general, the needs and welfare of the people.
The U.S. Army Corps of Engineers is soliciting comments from the public, federal, state,
and local agencies and officials, Indian Tribes, and other interested parties in order to consider
and evaluate the impacts of this proposed activity. Any comments received will be considered
by the U.S. Army Corps of Engineers to determine whether to make, modify, condition, or deny
a permit for this proposal. To make this decision, comments are used to assess impacts on
endangered species, historic properties, water quality, general environmental effects, and other
public interest factors listed above. Comments are used in the preparation of an Environmental
Assessment and/or an Environmental Impact Statement pursuant to the National Environmental
Policy Act. Comments are also used to determine the need for a public hearing and to
determine the overall public interest of the proposed activity.
The New Orleans District is unaware of properties listed on the National Register of
Historic Places near the proposed work. The possibility exists that the proposed work may
damage or destroy presently unknown archeological, scientific, prehistorical, historical sites, or
data. Copies of this public notice are being sent to the State Archeologist and State Historic
Preservation Officer regarding potential impacts to cultural resources.
Our initial finding is that the proposed work would neither affect any species listed as
endangered by the U.S. Departments of Interior or Commerce, nor affect any habitat designated as
critical to the survival and recovery of any endangered species. Based on the South Louisiana
Standard Local Operating Procedure for Endangered Species (SLOPES), as signed on October 22,
2014, between the U.S. Army Corps of Engineers, New Orleans and the U.S. Fish and Wildlife
Service, it has been determined that the project is located in waters known to be utilized by the
West Indian Manatee and determined that the activity is not likely to adversely affect this species.
This notice initiates the Essential Fish Habitat (EFH) consultation requirements of the
Magnuson-Stevens Fishery Conservation and Management Act. The applicant's proposal may
result in the destruction or alteration of 890 acres of EFH utilized by various life stages of red
drum and penaeid shrimp. Our initial determination is that the proposed action would not have
a substantial adverse impact on EFH or federally managed fisheries in the Gulf of Mexico. Our
final determination relative to project impacts and the need for mitigation measures is subject to
review by and coordination with the National Marine Fisheries Service.
If the proposed work involves deposits of dredged or fill material into navigable waters,
the evaluation of the probable impacts will include the application of guidelines established by
the Administrator of the Environmental Protection Agency. Also, a certification that the
proposed activity will not violate applicable water quality standards will be required from the
Department of Environmental Quality, before a Department of the Army permit is issued.
Any person may request, in writing, within the comment period specified in this notice,
that a public hearing be held to consider this application. Requests for public hearings shall
state, with particularity, the reasons for holding a public hearing.
The applicant has certified that the proposed activity described in the application
complies with and will be conducted in a manner that is consistent with the Louisiana Coastal
Resources Program. The Department of the Army permit will not be issued unless the applicant
received approval or a waiver of the Coastal Use Permit by the Department of Natural
Resources.
You are invited to communicate the information contained in this notice to any other
parties whom you deem likely to have interest in the matter.
