Disposition Instructions:

Item a: Record copy


Quality assurance records in Office of Research and Development (ORD) labs are not covered by this schedule. ORD quality assurance records that are for specific projects or research files are to be retained according to the disposition instructions for the records they support. For example, ORD quality assurance plans for scientific research projects related to rulemaking are to be retained with the records covered by EPA 501.

Reasons for Disposition:

The disposition instructions have been rewritten as media neutral to allow for maintaining the record copy in EPA's electronic recordkeeping system. The schedule was originally approved as N1-412-86-1/15a for the National Air and Radiation Environmental Laboratory. The title and description has been revised and the applicability expanded so that it can be used by all EPA laboratories. The retention has been reduced from 20 to 10 years.
