Where relevant and material matter offered in evidence is embraced
in a document containing other matter not material or relevant and not
intended to be put in evidence, the participant offering the same shall
plainly designate the matter so offered, segregating and excluding
insofar as practicable the immaterial or irrelevant parts. If other
matter in such document is in such bulk or extent as would necessarily
encumber the record, such document will not be received in evidence, but
may be marked for identification, and if properly authenticated, the
relevant and material parts thereof may be read into the record, or if
the administrative law judge so directs, a true copy of such matter in
proper form shall be received in evidence as an exhibit, and copies
shall be delivered by the participant offering the same to the other
parties or their attorneys appearing at the hearing, who shall be
afforded an opportunity to examine the entire document and to offer in
evidence in like manner other material and relevant portions thereof.
