NAVSUPINST 4570.23. Participation in the PMRP by
all Navy imaging facilities is mandatory.
The Defense Reutilization and Marketing Service,
Battle Creek, Michigan, is responsible for programs
associated with the collection, recovery, and processing
of precious metals. Navy imaging facilities turn in all
silver or silver-bearing materials to their local Defense
Reutilization and Marketing Office (DRMO). This
may include scrap film and paper, used fixer, exhausted
silver recovery cartridges, silver sludge, and silver
flakes from electrolytic recovery units.
Requests for PMRP supplies, such as silver test
paper, plastic collection containers, silver recovery
cartridges, fittings, control valves, and replacement
parts peculiar to silver recovery equipment, should be
coordinated with your local DRMO. Personnel in
DRMO will assist you in obtaining recovery equipment
to start up silver recovery operations or to enhance the
effectiveness of your current silver recovery operation.
Arrangements can then be made for a facility survey to
determine the specific requirements for on-site recovery
The manner in which a Navy imaging facility
handles silver-bearing solutions, exhausted recovery
cartridges, and silver sludge or flake is subject to
security requirements outlined by local authority. As a
minimum, however, the following security measures
are suggested:
Silver that has a high degree of purity should be
stored in a safe or locked cabinet within a locked room.
Bulky silver-bearing material, such as fixer and scrap
film and paper, should be stored in a locked room.
The weighing and measuring of silver-bearing
materials should be accomplished by a designated
weigher in the presence of a disinterested person and
the initials of both persons should appear on the weight
or inventory documentation.
NOTE: The same disinterested individual should
not be permitted to sign for more than two consecutive
Entry to an area where silver with a high degree
of purity is stored temporarily should be restricted to a
select group of personnel. Their names should be
posted on an access list that is kept current, limited to
people with a "need to know," and posted inside the
entrance. Visitors with a "need to know" who are
granted access be accompanied by an individual on the
access list and be required to sign a register. Personnel
on the access list do not require a security clearance.
Persons entering areas where silver or
silver-bearing material is stored should be made aware
of "condition of entry" by signs located inside the
entrance to the storage area.
