Now that the Obama Administration has okayed the Mexican trucking industries to do business in America, pesky environmentalists want those trucks to operate within U.S. standards. Lucky for the Mexican truckers, the U.S. taxpayer will pick up the tab to upgrade foreign-owned trucks ensuring their emissions meet environmental standards.
According to air-quality regulators, state or federal agencies cannot force trucks purchased and manufactured in Mexico to operate within the much-higher air-quality standards inside the U.S.
So clearly another problem with the North American Free Trade Agreement (NAFTA) presented itself. However, the folks at the Arizona Department of Environmental Quality (ADEQ) decided to implement a new program.
