Is it necessary to retain test substance storage containers for the duration of a field study?
Yes, as provided at 40 CFR 160.105(c), storage containers for test substances shall be assigned for the duration of a study. This requirement is necessary to assure that test substances are stored in proper containers, and that the containers that are used can be accounted for during the study. At any time during the study, it must be possible to examine the containers to assure that this standard is met. Top of page 2. Will EPA accept a “generic” alternative approach to cover multiple studies and/or test substances? More than one study and/or test substance may be included in given request, as long as each study and test substance is specifically identified. EPA’s response will address only those studies covered in the request.
