I work for a company that operates numerous bulk asphalt storage and paving grade production facilities. We've been using API RP 2023 (Guide for Safe Storage and Handling of Heated Petroleum...asphalt...) as a design guide...especially concerning pyrophoric iron sulfide deposit prevention. I've just noticed that RP 2023 appears to have been withdrawn by API. Does anyone on here that deals with storage of bitumen type products at elevated temps know what, if anything, would possibly have replaced RP 2023?

PS: It is just one of many we use, such as B31.3, API 2610, API 650, etc. It just did a good job of addressing the pyrophoric deposits.
