Breathing new life into a comatose certification application already through preliminary review.

Initial performance period 09/09/10 through 12/09/10.
Application submitted 04/02/12.
Preliminary review completed and reviewer's comments returned 05/03/12.
Applicant responses not yet submitted.

Application was submitted 60 days past final date of performance period and we are now more than 24 months past the initial start date of performance period. Project still has a pulse - a faint one, but still a pulse. Can we reset the performance period completely (say 01/01/13 through 03/31/13), respond to pending reviewer comments, undertake new tracking as required per credit and submit revived application?

If so, is this considered the same application or might this be considered a new application requiring new registration fees? Thanks.
