The Environmental Protection Commission (EPC) wants you to know there are steps you can take to maintaining your car, achieving better gas mileage and minimizing air pollution!  Ground level ozone is a pollutant that can irritate lungs and make our breathing more difficult. Our personal vehicles contribute to almost 1/3 of our ozone problems.  If every driver in Hillsborough County will employ a few simple steps, we can minimize our ozone levels and save money on fuel at the same time!
