Requires the posting of a public notice in the facility stating the nondiscriminatory policy. Permits the Secretary to revoke the acceptance of the statement of nondiscrimination.

Requires the taxpayer to report any amounts paid or incurred for food, beverages, lodging, or entertainment in any facility which is not open to the public or does not serve the public.
