ClarificationThe U.S. International Boundary <strong>and</strong> <strong>Water</strong> Commission (IBWC) coordinates with itssister agency in Mexico (CILA) on water quality challenges in binational watersheds.Requirements to maintain water quality for the protection of binational investmentsin infrastructure are formalized in a binational treaty between IBWC <strong>and</strong> CILA(Minute 276) with title “Conveyance, Treatment <strong>and</strong> Disposal of Sewage fromNogales, <strong>Arizona</strong> <strong>and</strong> Nogales, Sonora Exceeding the Capacities Allotted to theUnited States <strong>and</strong> Mexico Under Minute Number 227.”In matters dealing with binational wastewater qualityIBWC/CILA have precedence.For additional details, please see page 2, last paragraph <strong>and</strong> page 4, point #6 of the minute available here:http://www.ibwc.gov/Files/Minutes/Min276.pdf .
