A A ::earch was conducted to determine what actions were taken as a result of the' amendment to Appendix H pub!!shed in the Federal Register (48 FR 24008 effective
- ~
The changes to Appendix H make its requirements more flex)ible by July 26,1983.
expanding the acceptable editions of ASTM E-185 to include the 1982 version, deleting duplication of specific pmvisions in ASTM E 185, deleting provisions which wore duplicated in Appendix G, and expanding criteria for an acceptable integrated surveillance program. Proposed reporting requirements also were relaxed in the final rule. These circumstances are consistent with our determination that objective.
evidence of a review in 1983 was not found. However, we can conclude from reviews conducted for Generic Letter 92-01 that compliance with Appendix H was maintained.
