In most cases, you are permitted to correspond with the public, family members,
and others without prior approval or the maintenance of a correspondence list. Outgoing mail is placed in mailboxes
located in the housing units. All letters may be sealed with the exception of mail between confined persons. That mail may
not be sealed. Correspondence with any other confined person must first be approved by the Unit Managers and/or
Wardens of both institutions. See your counselor for further details.
You are responsible for the content of all your letters. Correspondence containing threats, extortion, etc. may result in
prosecution for violation of federal laws. You may be placed on restricted correspondence status based on misconduct or
as a matter of classification. You will be notified of this restriction.

the address. You must also place your quarters’ designation in your return address. Below is how your return address
