# SUPPLEMENTARY INFORMATION:

                    On June 4, 2009, the USIBWC issued a Record of Decision (ROD) on the long-term management of the RGCP in southern New Mexico and western Texas. The ROD committed the USIBWC to the restoration of aquatic and riparian habitat at up to 30 sites over 10 years (through 2019). In May 2019, the USIBWC prepared a Draft EA to analyze the potential impact of seven action alternatives and a No Action Alternative to implement aquatic habitat within the RGCP, and the USIBWC extended the comment period (                    **Federal Register**                     July 22, 2019). After public input and subsequent development of preliminary designs, USIBWC re-evaluated alternative sites for aquatic habitat and assessed the feasibility of three additional sites, two of which were added to the EA. The USIBWC has prepared an Amended Draft EA, which evaluates potential impacts of ten alternatives, including the No Action Alternative and the following sites: Yeso Arroyo, Angostura Arroyo, Broad Canyon Arroyo, Selden Point Bar, Las Cruces Effluent, Mesilla Valley Bosque State Park, Downstream of Courchesne Bridge, Trujillo Restoration Site, and Montoya Intercepting Drain.                

                    Restoration actions could include invasive vegetation removal, native vegetation planting, overbank lowering, bank cuts, natural levee breaches, secondary channels, bank                           ( print page 10335)                        destabilization, channel widening, arroyo mouth management, construction of inset floodplains, construction of wetland depressions, and use of supplemental water for on-site irrigation.                

Based on a review of the facts and analyses contained in the Amended Draft EA, the USIBWC has selected five projects as the Preferred Alternatives: Alternative D—Broad Canyon Arroyo, Alternative F—Las Cruces Effluent, Alternative G—Mesilla Valley Bosque State Park (MVBSP), Alternative H—Downstream of Courchesne Bridge, and Alternative J—Trujillo Arroyo. Alternatives Las Cruces Effluent and Downstream of Courchesne Bridge would require engineering designs prior to construction, while Alternatives Broad Canyon Arroyo and Trujillo Restoration Site, which are smaller and less complicated projects, could be constructed from conceptual designs. Downstream of Courchesne Bridge would be implemented as part of compensatory mitigation for future levee improvement projects. All alternatives would require appropriate permits from the United States 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 in the Draft EA. The USIBWC has prepared a FONSI for the Preferred Alternatives, based on a review of the facts and analyses contained in the amended Draft EA.

*Availability:*                     The electronic version of the amended Draft EA is available at the USIBWC web page:                     *https://www.ibwc.gov/​EMD/​EIS_​EA_​Public_​Comment.html.*
