The environmental assessment of this federally assisted action indicates that the project will not cause significant local, regional, or national impacts on the environment. As a result of these findings, Larry D. Butler, PhD, State Conservationist, has determined that the preparation and review of an environmental impact statement is not needed for this project.

The project will rehabilitate Floodwater Retarding Structure No. 6A to maintain the present level of flood control benefits and comply with the current performance and safety standards.

Rehabilitation of the site will require the dam to be modified to meet current performance and safety standards for a high hazard dam. The modification will consist of raising the top of dam 3.1 feet, installation of an additional principal spillway (36″ hooded inlet type with an impact basin), and widening both auxiliary spillways 50′ to accommodate the construction of splitter dikes. All disturbed areas will be planted to adapted native and/or introduced species. The proposed work will not have a significant affect on any prime farmland, endangered or threatened species, wetlands, or cultural resources.

Federal assistance will be provided under authority of the Small Watershed Rehabilitation Amendments of 2000 (Section 313, Pub. L. 106-472). Total project cost is estimated to be $1,627,100, of which $1,151,500 will be paid from the Small Watershed Rehabilitation funds and $475,600 from local funds.

The notice of a Finding of No Significant Impact (FONSI) has been forwarded to the Environmental Protection Agency and to various Federal, State, and local agencies and interested parties. A limited number of copies of the FONSI are available to fill single copy requests at the above address. Basic data developed during the environmental assessment are on file and may be reviewed by contacting Larry D. Butler, PhD, State Conservationist.

No administrative action on implementation of the proposal will be taken until 30 days after the date of this publication in the Federal Register.
