Specifically, you asked if this type of arrangement is allowed when transporting LSA\nmaterials.\nThe answer is yes, provided the sump is not the cargo tank outlet used for normal loading or\nunloading of the tank. See §§ 178.345-1 and 178.345-11.\nI hope this information satisfies your inquiry.\nSincerely,\nThomas G.

Reference\n178.345-1, under the definition of \"outlet,\" states that the following are not outlets: \"A threaded\nopening securely closed during transportation with a threaded plug or a threaded cap, a flanged\nopening securely closed during transportation with a bolted or welded blank flange....\nDynCorp's interpretation of the regulations allows a securely closed, bolted blank flange on the\nbottom of the DOT 412 cargo tank when transporting LSA liquids, does DOT concur?\nWe are requesting a written interpretation for the U.S. Department of Energy, Richland\nOperations Office.\nVery truly yours,\nThomas (-Savage\nI.
