Finding of No Significant Impact

Tennessee State Route 33 (US 411) Improvements

McMinn and Monroe Counties, Tennessee

The Tennessee Department of Transportation (TDOT) proposes to construct a portion of Sections VI and VII of the proposed State Route (SR) 33 improvement project. In this permit application, TVA has been asked to review this 5.593-mile section, the northernmost phase, of the 14.1-mile project for required approvals under Section 26a of the TVA Act.

In 1992 the Federal Highway Administration (FHWA) and TDOT completed an environmental assessment (EA) for the improvements and widening of SR 33 from 0.2 mile north of SR 30 in Etowah to the existing four-lane section south of Madisonville in McMinn and Monroe counties, Tennessee. The entire 14.1-mile project is described in the referenced EA. This EA also covers the improvements along the northernmost portion of SR 33, currently under review by TVA. No TVA land or land rights are involved.

This northernmost project phase includes proposed improvements and widening (to the northwest side) of SR 33 from just south of the McMinn County line north to the Madisonville Bypass along its existing alignment. Construction along this portion of the roadway would consist of four 12-foot-wide lanes, a 50-foot median, a 10-foot-wide paved shoulder, culvert extension, and various typical drainage and ditch works. These improvements would affect Cave Springs and Carson Branches and other unnamed tributaries confluent to Chestuee Creek, as well as a spring, pond, and five small wetland areas.

This northernmost portion of the project would also involve replacement or extension of five box or concrete pipe culverts affecting Cave Springs Branch and other unnamed tributaries. A total of 0.74-acre of wetlands at four locations in the vicinity and just north of Cave Springs Branch, as well as another wetland location along SR 33 just south of Madisonville, would be permanently affected. About 350 total feet of riprap would be needed in the floodplain at seven locations (less than 50 feet at each location) to minimize streambed and bank erosion at culvert inlets and outlets. Affected utility lines, including those conveying electric power, water, sewer, and gas, would be modified as needed to continue or improve service.

The portion of the project covered in the 1992 FHWA/TDOT EA between Etowah to just south of the McMinn County line, including that portion of SR 33 through Englewood, has been completed. Work on improvements to SR 33 south of Etowah and SR 30 is in progress.

TVA proposes to approve construction of SR 33 improvements for this northernmost 5.593-mile section, from just south of the McMinn County line north to the Madisonville Bypass. The Section 26a request for approvals for this portion of the project involves mitigation of site-specific stream and wetland impacts that were identified in the TDOT project description and application.

This TVA FONSI independently evaluates effects on environmental resources for this portion of the project impact area (also see Impacts Assessment Section in the attached FONSI). TVA staff inspected the entire 14.1-mile project, including this 5.593-mile portion of SR 33, on June 8, 2005. Mitigation for impacts to wetlands and streams are discussed in the attached FONSI and details are provided in the referenced EA.

TVA issued its permit on September 30, 2005.
