Summary

The Administrator must study how particulate matter from motor vehicles and their engines affects health and welfare. The study must measure and describe those emissions, and look at how different fuels and fuel additives change them. It must also study particulate matter from mobile sources that are not engine exhaust, such as tire debris and asbestos from brake linings. The Administrator must send a report of the findings to Congress no later than two years after August 7, 1977. The report must also give recommendations for standards or ways to control the non-engine particulate emissions described above.
