Section 404 / 401 Permitting
PERMITTING FOR RELOCATION OF SHIPYARD
Wepfer Marine operated a full-service shipyard with drydocks and barge cleaning services at a facility on Channel Avenue for years before needing to relocate its services further west on Presidents Island. The marine services company proposed the installation of service docks on McKellar Lake at the Port of Memphis that included a series of barges, dry docks, and crane systems.
McKellar Lake is considered a navigable water of the U.S. and installation of the dock system required Section 10 and 404 permits through the U.S. Army Corps of Engineers (USACE) and Section 401 and Aquatic Resource Alteration Permits (ARAP) through the Tennessee Department of Environment and Conservation (TDEC). Tioga was tasked with determining the jurisdictional extent of the water feature, evaluating the site ecology for potential impacts to endangered species, and developing the necessary permit documentation, including schematics of impacts, calculation of fill materials, and design of mitigation measures.
Activities that required permitting included the following: installation of a floating dock system; 0.34 acres of fill for the dock access driveway construction; up to 2.40 acres of additional fill for miscellaneous bank stabilization; and clearing of vegetation along the length of the property shoreline. Based on the scope of the project, both the USACE and TDEC required the facility to obtain an individual permit, requiring additional review and public notice. Tioga was able to mediate between the agencies, the client and client’s engineer, and the Port of Memphis to obtain the necessary permitting in a timely manner.
