Sec.  51.15  May I clarify, amend or supplement my proposal after it 
is submitted?

    (a) The Director may request from any offeror who has submitted a 
timely proposal a written clarification of its proposal. Clarification 
refers to making clear any ambiguities that may have been contained in a 
proposal but does not include amendment or supplementation of a 
proposal. An offeror may not amend or supplement a proposal after the 
submission date unless

requested by the Director to do so and the Director provides all 
offerors that submitted proposals a similar opportunity to amend or 
supplement their proposals. Permitted amendments must be limited to 
modifying particular aspects of proposals resulting from a general 
failure of offerors to understand particular requirements of a 
prospectus or a general failure of offerors to submit particular 
information required by a prospectus.
    (b) A proposal may suggest changes to the terms and conditions of a 
proposed concession contract and still be considered as responsive so 
long as the suggested changes are not conditions to acceptance of the 
terms and conditions of the proposed concession contract. The fact that 
a proposal may suggest changes to the proposed concession contract does 
not mean that the Director may accept those changes without a 
resolicitation of the concession opportunity.
