    Background: The USIBWC is considering constructing sediment control 
projects at Thurman I and II, two ephemeral tributaries of the Rio 
Grande, located within a portion of the Rio Grande Canalization Project 
protective levee system in Hatch, Do[ntilde]a Ana County, New Mexico. 
The USIBWC has the statutory authority to maintain the Rio Grande (Act 
of June 4, 1936, 49 Stat. 1463, Pub. L. 648 and 22 United States Code 
277). USIBWC commissioned a study in 2015 that recommended sediment 
control structures be built on Thurman I and II arroyos, among others, 
to trap sediment and assist in the maintenance of the Rio Grande.
    The purpose is to construct sediment control structures on Thurman 
I and II arroyos with the following objectives:
    (1) Control the inflow of sediment into the Rio Grande mainstem,
    (2) Conduct a pilot study for channel maintenance alternatives, and
    (3) Be accessible for maintenance and minimize operational costs.
    This EA evaluates potential environmental impacts of the No Action 
Alternative and two alternatives. The Alternative A: No Action--Routine 
Sediment Excavation does not call for any construction but would 
require continued routine sediment excavation at the confluence of the 
arroyos and the Rio Grande. Alternative B: Mesh-Based Sediment Traps 
proposes to construct mesh and rebar sediment traps where each mesh 
would trap progressively smaller sediment particles. Alternative C: 
Sediment Basins is the Preferred Alternative, and calls for the 
construction of a sediment basin at each arroyo with a concrete end 
wall. Permits would be required from the U.S. Army Corps of Engineers 
for dredge and fill of Waters of the United States, per the Clean Water 
Act Sections 404 and 401.
    Potential impacts on natural, cultural, and other resources were 
evaluated. Mitigation has been proposed for permits for construction. A 
Finding of No Significant Impact has been prepared for the Preferred 
Alternative based on a review of the facts and analyses contained in 
the EA.
