Nation President Kelsey A. Begaye has signed measures to lower the DUI level and strengthen enforcement of trash disposal laws. The council recently approved a resolution dropping the blood-alcohol level for presumption of intoxication to 0.08 percent from 0.10, the current statewide level for Arizona though there is a move to change it to avoid loss of millions of dollars in federal highway funds. Begaye also signed a resolution reallocating funds to ensure use of three Navajo Environmental Protection Agency officers to enforce reservation trash disposal laws. There is no door-to-door trash collection on the 4.8 million-acre reservation. Open dumping is a tradition the nation is trying to change. The tribal environmental agency identified 465 makeshift, illegal dumps on the reservation in 1999 when a crackdown began.
