    Pima County Department of Environmental Quality (PDEQ), formed in 1989, serves Pima County by protecting public health and the environment.  PDEQ operates programs to monitor air and water quality, hazardous waste, solid waste, and assist in waste minimization and pollution prevention.  PDEQ also provides public outreach, education, and citizens' assistance; processes environmental permits; and responds to public complaints and inquiries with investigations and enforcement.

    Our Mission

    Pump Up Your MPGPDEQ launched a special "Pump Up Your MPG" contest and educational program this year to encourage proper tire inflation to save fuel and reduce vehicle-related emissions. Monthly tire pressure checks can save you up to $400 a year in fuel and extend the life of your tires. The contest is over now and the prize winners were chosen through a random drawing.
