The four boxes in this series were a later accession to the already existing materials arranged in Series 1. These materials came out of two banker's boxes and pertain to the cleanup and remediation of the pesticide waste pits in the early 2000s. The contents of boxes 13 through 15 had sticky notes with identifying numbers that were preserved on the titles of the folders. The material was arranged in numberical order based on the attached notes; not every number was present.
