MEMORANDUM FOR: DDP/EXO
SUBJECT: Agency Chain Envelope, Form No. 1138
5 February 1957
1. The factors motivating a proposal to standardize on the
subject envelope can be well appreciated by RI from a managerial vier
point. However, standardization to include all elements of the Agency,
and. the DDP specifically is objected to, not for purposes of administration
but for reasons of operational security. Elements of the DDP use envelope
coverings for transmission of material not only to the overt portions of
the organization, but also to other DDP units situated in various buildings
removed. from the I, J, K, L Building complex, as well as to the DDCI and,
the DCI. A fact, probably best realized. by DDP personnel is that much of
this material is of such a sensitive operational nature that restrictions
have been imposed even within the DDP area as to access to it and. indicators
such as KAPOK and.RYBAT are in use to insure its limited,d.istribution.
I
Documents within CIA) requires that chain envelopes be sealed by means of
a gummed. label. Instructions for use of the proposed envelope require
specifically that this not be done. also makes provision
for double wrapping as does the proposed. instruction.-
3. It is the opinion of RI that the requirements set forth in the
aforementioned regulation present a minumum precaution to be followed. for
the secure transmission of documents. The DDP chooses to follow a security
maximum in precautionary measures when the sensitivity of information
involved necessitates it.
11. Those best equipped. to judge the sensitivity of DDP operations
are personnel of the DDP. To require use of the proposed. envelope is to
require the abolition of reliable self imposed security requirements which
have been necessitated by the nature of the documents we handle. RI
recommends that for transmission of DDP mail, use of a pla' Lila envelope
sealed, be continued.
