JUN 1, 2016 -SOURCE: NAPA NATIONAL ASPHALT PAVEMENT ASSOCIATION Markings for tanks that contain AC binder, fuel oils, and even asphalt mixture can be confusing because requirements span a number of different federal, state, and local agencies. The labeling information provided in NAPA’s tank inspection guidance document (IS 137 Supplement) should be sufficient for compliance with federal and most state and local requirements with the inclusion of a tank numbering/identification system. More specific information is provided in this report.
Three basic sets of regulations govern requirements for marking liquid storage tanks: federal and state environmental agency rules, OSHA’s Hazard Communication standard, and local fire district requirements. State- and jurisdiction-specific markings may also be required: please check with appropriate state and local agencies.
