Washington, D.C. ­– U.S. Senators John McCain (R-AZ) and Jeff Flake (R-AZ) this week introduced in the Senate the Nogales Wastewater Fairness Act, legislation that would transfer the unfair financial burden of maintenance and capital upgrades of the International Outfall Interceptor (IOI) sewage pipeline located underneath the Nogales Wash along the Arizona-Mexico border from the city of Nogales, Arizona, to the International Boundary and Water Commission (IBWC). Representative Martha McSally also introduced companion legislation in the House of Representatives.

Under an existing agreement between the IBWC and Nogales, the city is currently responsible for a disproportionate percentage of the operating costs of the IOI. The Nogales Wastewater Fairness Act would transfer future capital costs to the IBWC while holding the city of Nogales responsible only for its equitable proportion of operation and maintenance costs that would be fairly split based on the city’s average sewage flow.

“At its core, the 1953 financial arrangement between Nogales and IBWC is outdated and unfair,” said Senator McCain. “Nogales residents should not have to pay for runoff and sewage not under their control. Our bill finally brings fairness to the people of Nogales who are dealing with out-of-touch bureaucrats mismanaging this crumbling infrastructure.” 

“The burden of wastewater infrastructure operated pursuant to a U.S.-Mexico treaty should not fall disproportionately on the City of Nogales,” said Senator Flake. “This bill resets the cost-share to reflect the proper obligations of the IBWC.”

“Nogales has shouldered an unfair burden in paying for the operation and maintenance of this pipeline for too long,” said Rep. McSally. “I am happy to join Senator McCain today in introducing the Nogales Wastewater Fairness Act. This legislation will help address a longstanding problem and I look forward to working alongside him to get this passed through Congress and onto the President’s desk.”

“We are grateful for the tremendous support from Senators McCain and Flake and Congresswoman McSally on this effort,” said Guillermo Valencia, Chairman of the Greater Nogales Santa Cruz County Port Authority. “The Greater Nogales Santa Cruz County Port Authority has for many years advocated for the urgent need to address the issue of the IOI and after trips to Washington, D.C., arranging numerous site visits and meetings with many stakeholders, we are extremely glad to see the Senator take the lead to provide a solution. This is an issue that impacts the quality of life of the residents of Nogales, Arizona. But it also has a direct impact on the lives of the residents of Nogales, Mexico, and the entire Nogales-Tucson corridor. The significance of this legislation cannot be overstated.”
