The December 2023 RBCA guidance document will be allowed for use at Petroleum Release Sites once the RBCA reference is updated in rule.  The “Incorporation by Reference Rulemaking”, MAR – 17-438, that proposes to update the RBCA guidance to the December 2023 version is currently in progress and expected to be final in May 2024.
