A bill to authorize the International Boundary and Water Commission to accept funds for activities relating to wastewater treatment and flood control works, and for other purposes.

This bill authorizes the International Boundary and Water Commission (IBWC) to accept funds from Federal or non-Federal entities for studying, designing, constructing, operating, or maintaining wastewater treatment, water conservation, and flood control works. These accepted funds will be deposited into a dedicated Treasury account and remain available until expended for the specified activities. The legislation includes important limitations, such as a $5,000,000 annual cap on reimbursement or credit towards non-Federal shares. It also strictly prohibits the Commission from accepting funds from non-Federal entities domiciled in, headquartered in, or having agreements with a "foreign country of concern." To ensure transparency, the IBWC is required to submit an annual report to Congress detailing the activities and costs associated with these funds.
