First AEGL Chemical Priority List

The First AEGL Chemical Priority List appeared in the May 21, 1997 Federal Register Page 27733-27734 and listed 85 chemicals.

An additional 15 chemicals were added to this list subsequently. All 100 First AEGL Chemical Priority List chemicals were viewed as high priority for AEGL development, based on their nomination by AEGL Committee stakeholders and overlap of interest among many different organizations.
