; (15) during the 20-year period before the date of enactment of this Act, the United States and Mexico, through the International Boundary and Water Commission, have agreed to resolve the pollution problems in the Tijuana River; (16) the International Boundary and Water Commission has negotiated 8 minutes to resolve water quality problems in the Tijuana River, among other subjects; (17) 1 of the most recent minutes authorized the construction of the South Bay International Wastewater Treatment Plant in San Ysidro to treat, on average, 25,000,000 gallons of sewage from Tijuana per day, which has reduced the sewage coming into the United States; (18) the sewer system of Tijuana is— (A) aging and deteriorating; and (B) insufficient to meet the needs of a quickly growing population; (19) in February 2017, 1 of the main sewer collectors of Tijuana broke, sending an estimated 143,000,000 gallons of raw sewage into the United States, which was not the only time such a break occurred; (20) from February to July of 2019, an estimated 4,500,000,000 gallons of wastewater, treated water, and stormwater flowed from Mexico to the United States; (21) in June and July 2019, there were 3 sewer collector breaks, resulting in a total discharge of raw sewage of almost 2,000,000 gallons; (22) a 2019 study entitled Tijuana River Diversion Study: Flow Estimates, Infrastructure Diagnostic, and Alternatives Development estimated that from 2009 through 2016, transboundary flows occurred on average 138 days each year; (23) those transboundary flows contain treated wastewater, raw sewage, and urban runoff, with most of those flows associated with wet weather and stormwater; (24) the study described in paragraph (22)— (A) found that improving the operational reliability of the existing diversion system of the South Bay could reduce the number of days that transboundary flows occurred; but (B) estimated that there would still be on average 90 days of transboundary flows each year
