Yes, most of the codes require 100-110% containment. The tank(s) should be designed double skin and have specific venting requirements for methanol or amine storage. Refer also to the local government regulations regarding the storage and handling of flammable and combustible liquids. You might need also refer to specific standards like UL-142 or similar. Conversely, you should look up the design and operating conditions for amine service. Venting and blanketing is a big issue.
Finally, your question is tricky because you cannot have a concrete bund for amine service, but you might have one for methanol service, depending on concentration, location, etc.
