Rehabilitation of Floodwater Retarding Structure No. 10 of the 
Mountain Creek Watershed, Ellis County, TX

AGENCY: Natural Resources Conservation Service.

ACTION: Notice of a Finding of No Significant Impact.

-----------------------------------------------------------------------

SUMMARY: Pursuant to Section 102(2)(c) of the National Environmental 
Policy Act of 1969; the Council on Environmental Quality Regulations 
(40 CFR part 1500); and the Natural Resources Conservation Service 
Regulations (7 CFR part 650); the Natural Resources Conservation 
Service, U.S. Department of Agriculture, gives notice that an 
environmental impact statement is not being prepared for the 
rehabilitation of Floodwater Retarding Structure No. 10 of the Mountain 
Creek Watershed, Ellis County, Texas.

FOR FURTHER INFORMATION CONTACT: Donald W. Gohmert, State 
Conservationist, Natural Resources Conservation Service, 101 South 
Main, Temple, Texas 76501-7682, Telephone (254) 742-9800.

SUPPLEMENTARY INFORMATION: 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, Donald W. Gohmert, 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. 10 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 net elevation of the top 
of dam elevation 3.1 feet to 602.4 feet, install a new two-stage 
principal spillway (standard drop inlet type) with a port at elevation 
575.14 feet and crest at elevation 576.8 feet, install a new 42 inch 
pipe, and install an impact basin to replace the existing plunge pool. 
The new principal spillway crest elevation will be raised by 1.5 feet. 
Flatten the back slope to a 3\1/2\:1 slope, lime treat the embankment 
slopes, and install a new toe drain system along back toe of dam. Lower 
the crest of the auxiliary spillway 1.4 feet to elevation 592.6 feet 
and reshape the outlet section of the auxiliary spillway. All disturbed 
areas will be planted to adapted native and/or introduced plant 
species. The proposed work will not have a significant effect 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 $2,805,600, of which 
$1,981,100 will be paid from the Small Watershed Rehabilitation funds 
and $824,500 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 
Donald W. Gohmert, 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.

    Dated: June 28, 2010.
Donald W. Gohmert,
State Conservationist.
