Archived Rulemaking: Elevated Temperature Materials

RSPA is delaying the compliance dates for certain provisions of a final rule concerning elevated temperature materials and clarifying the effective date of this final rule in conjunction with the final rule published December 21, 1990, under Docket HM181. This action is in response to numerous petitions asking RSPA to delay the compliance dates contained in the rule to allow affected entities sufficient time to come into compliance with the new requirements and to provide RSPA additional time to review petitions for reconsideration received in response to the final rule. RSPA will respond to other petitions for reconsideration in a separate document.
