A bill to amend the Internal Revenue Code of 1986 to provide that, in order to assist barge and other riverboat operators who are adversely affected by the drought, the Inland Waterways Trust Fund fuel tax shall not apply during certain periods.

Suspends imposition of the Inland Waterways Trust Fund financing rate (a tax of ten cents per gallon of fuel used in inland waterway transportation) between July 1, 1988, and December 31, 1988. Requires continued suspension, through June 30, 1989, if the Secretary of the Treasury determines that continuing adverse effects of the 1988 drought warrant it.
