If the claimant submits factual evidence, medical evidence, or both,
but OWCP determines that this evidence is not sufficient to meet the
burden of proof, OWCP will inform the claimant of the additional
evidence needed. The claimant will be allowed at least 30 days to submit
the evidence required. OWCP is not required to notify the claimant a
second time if the evidence submitted in response to its first request
is not sufficient to meet the burden of proof.
