Amends the Emergency Petroleum Allocation Act of 1973 to direct the President to prohibit suppliers of refined petroleum products from curtailing operations within any State by more than ten percent of total output without 180 days' prior written notice to the Governor of the affected State. Stipulates that such curtailments shall not exceed, within any six-month period, 25 percent of the total output of such supplier in that particular State.

Limits the applicability of such requirements to marketers and distributors whose operations comprise at least two percent of the total market in such State.
