In addition, the claimant may be required to submit to a physical or mental examination by a physician employed or designated by EPA. A copy of the report of the examining physician shall be made available to the claimant upon the claimant's written request provided that the claimant has, upon request, furnished the report referred to in the first sentence of this subparagraph and has made or agrees in writing to make available to EPA any other physician's reports previously or thereafter made of the physical or mental condition which is the subject matter of his claim.

The claim may be thereupon disallowed.
