Vulcan Little Wolf Creek Culvert Extension
Vulcan Construction Materials, LP (Vulcan) proposes to place 200 feet of 96-inch I.D. corrugated metal pipe (culvert) into Little Wolf Creek in order to facilitate the ongoing operations of its Benton County Rock Quarry. The new pipe would connect to an existing 96-inch culvert and nearly extend to the confluence of Wolf Creek. Installation of an additional culvert into this section of the creek would allow Vulcan to expand and maximize use of its existing work area, providing more flexibility to move equipment and vehicles as well as more room to stockpile quarried rock. Including past authorizations, this would increase the total length of Little Wolf Creek encapsulation on the Vulcan processing yard to 600 feet.
To mitigate impacts of the loss of an additional 200 feet of Little Wolf Creek, Vulcan will rehabilitate internal quarry drainage features, remove accumulated sediment from existing culverts and place this material where it can be vegetated or in an overburden storage area depending on the constituents of the material. Vulcan will also enhance and restore four sites within a 1,000 feet reach of Wolf Creek downstream from the proposed culvert location and its confluence with Little Wolf Creek. Upon cessation of mining operations, Tennessee Department of Environment and Conservation will also require Vulcan to remove existing culverts (575 feet) from the processing plant yard and restore Little Wolf Creek. This will ensure that there are no long-term cumulative effects from this mine operation on the Wolf Creek watershed. A section of culvert will remain at one 25-foot wide road crossing to provide landowner access (click on Finding of No Significant Impact (FONSI) below or, upon request, see a copy of the U.S. Army Corps of Engineers (USACE) final environmental assessment (EA) and FONSI for more project details).
Construction of an obstruction in Little Wolf Creek requires approval under Section 26a of the TVA Act. Little Wolf Creek is confluent to Wolf Creek, which drains into Birdsong Creek and then the Tennessee River (Kentucky Reservoir) at Mile 103.5. TVA issued its permit on July 15, 2005.
