Dear Mr. Savage:

This responds to your letter regarding the transport of low specific activity (LSA) liquid in a specification DOT 412 cargo tank with a sump which has been securely closed by a threaded cap or bolted flange. Specifically, you asked if this type of arrangement is allowed when transporting LSA materials.

The answer is yes, provided the sump is not the cargo tank outlet used for normal loading or unloading of the tank.  See §§ 178.345-1 and 178.345-11.

I hope this information satisfies your inquiry.
