PUBLIC NOTICE OF APPLICATION FOR COASTAL WETLANDS PERMIT AND WATER QUALITY CERTIFICATION

PUBLIC NOTICE OF APPLICATION
FOR COASTAL WETLANDS PERMIT
AND WATER QUALITY CERTIFICATION

The Mississippi Department of Marine Resources (MDMR) has filed an application requesting permission to conduct regulated activities under the provision of the Coastal Wetlands Protection Law Act, Title 49, Chapter 27, Mississippi Code of 1972.

The applicant is proposing to construct the Deer Island Habitat Restoration (DIHR) Beneficial Use (BU) site, for the disposal of suitable dredged material.  The approximate 70-acre site will be located on the north-central side of the island west of the entrance to Grand Bayou.  Containment of material at the site will be composed of earthen berms constructed from on-site material, placed mechanically, and sand sourced from the Black Warrior-Tombigbee River system, placed hydraulically.  The outer containment berm will be approximately 4,520 feet in length and will be placed at approximately the -4’ below MLLW contour.  Maximum height of the outer berm will be approximately 6 feet above MLLW.  The inner containment berm will be placed along the mean high tide line of the Deer Island shoreline and extend for approximately 1,975 feet at an elevation of 4 feet above MLLW.   For the interior disposal area, the dredged material will be pumped to a height of 3 feet to 5 feet above mean lower low water (MLLW), with final grade after dewatering and consolidation, ranging from -0.5’ to 1.5’ MLLW.   The eastern end of the containment structure will remain open to allow for tidal flushing as well as continuation of the marsh adjacent to Grand Bayou.  Two access channels each measuring 1,000 feet in length and 60 feet in width may be dredged to -10 feet below MLLW on the east and west side of the site to allow barge access for mechanical offloading of material.  The material from these access channels would be placed in the littoral zone to the west of the channel to re-nourish the island.  The anticipated capacity of this site will be between 470,000 and 575,000 cubic yards and both access channels would need to be maintained for the 10-year life of the permit, or until capacity is reached.   Once construction and dewatering are complete, the outside containment berm and the entire 70-acre site will be planted with appropriate marsh and dune species to supplement the natural recruitment of vegetation at the site. The area will also become the latest addition to the Deer Island Coastal Preserve which is managed by MDMR. MDMR is requesting a variance from Chapter 8, Section 2, Part III.O.1 of the Mississippi Coastal Program (MCP) which states: “Permanent filling of coastal wetlands because of potential adverse and cumulative environmental impacts is discouraged.” This public notice and project diagrams may be accessed on MDMR’s website at :  http://www.dmr.ms.gov/index.php/coastal-resources-management/wetland-permitting.

In compliance with Section 401 of the Federal Water Pollution Control Act (33 U.S.C. 1251, 1341), as amended by PL 95-217, the applicant will request certification from the Office of Pollution Control that the above mentioned activity will be in compliance with applicable provisions of Section 301 (33 U.S.C. 1311), Section 302 (33 U.S.C. 1312), Section 303 (U.S.C. 1313), Section 306 (U.S.C. 1316), and Section 307 (U.S.C. 1317) of the Act and appropriate requirements of the State Law.

Any person wishing to make comments or objections to the proposed regulated activity must submit those comments in writing to the Department of Marine Resources at 1141 Bayview Avenue, Biloxi, Mississippi 39530 before 1:00 p.m. on the day July 16, 2018.
