Environmental Defense Fund (EDF) today released a report titled “Review of Texas’ Clean School Bus Programs: How Far Have We Come and What Is Still Left to Do?” This report evaluates each of the clean school bus programs in Texas, reviews accomplishments, and offers suggestions for improvement.
Diesel engines power most of the estimated 480,000 school buses in the United States, and the World Health Organization recently classified diesel exhaust as a known carcinogen, specifically noting a causal link between exposure to diesel exhaust and lung cancer. One of the most dangerous components of diesel exhaust is particulate matter (PM). The Environmental Protection Agency (EPA) is particularly concerned with these smallest-sized particles, because they are known to aggravate asthma, cause lung inflammation, lead to heart problems, and increase the risk of cancer and premature death.
Texas children riding to school in buses built before 2007 may be breathing air inside the cabin of the bus that contains 5-10 times higher the amount of diesel pollution than found outside the bus. These older bus engines spew nearly 40 toxic substances and smog-forming emissions. Children, who breathe in more air per pound of body weight than adults, are therefore exposed to even higher health risks because their lungs are still developing.
As of the 2010-2011 school year, the Texas Education Agency reported that nearly two-thirds of current school buses were over six years old, emitting at least 10 times as much PM as newer buses, and much more in many cases because a large proportion of the fleet is even older. More than 700,000 children are impacted, meaning that nearly half of the students relying on school buses for transportation in Texas still ride dirty buses.
Texas has made a great deal of progress with clean bus programs. Through the end of the 2011 calendar year, 7,068 buses were retrofitted, 700 buses were replaced, and several other projects related to clean fuels and idle reduction were successfully implemented in Texas. Over $38 million has been spent on these projects, with funding received from the federal and state government, as well as from local donors.
“I’m thrilled to see the progress we’ve made with the Texas clean school bus programs,” said Elena Craft, Health Scientist at EDF. “But our work is not finished. I hope that school districts will take advantage of available programs and remaining funds to clean up the older, more polluting school buses.”
There are two current programs available to help retrofit or replace the remaining 17,000 dirty schools buses in Texas. Under the Texas Clean School Bus Program, The Texas Commission on Environmental Quality (TCEQ) is accepting applications for grants through November 30. This is a comprehensive program designed to reduce diesel exhaust emissions through school bus retrofits. All public school districts and charter schools in Texas are eligible to apply for this grant. Private schools are not eligible for funding. Public school districts that lease buses are also eligible.
EPA also launched a new rebate funding opportunity for school bus replacements under the Diesel Emissions Reduction Act. Applications will be accepted from Nov. 13 to Dec. 14. The first round of rebates will be offered as part of a pilot program and will focus on the replacement of older school buses in both public and private fleets. If the pilot proves successful, EPA will look at rebates for other fleet types and technologies.
