Upon the request of an indigent incarcerated individual, staff shall provide an incarcerated individual with pen, paper, envelopes, and first-class postage for seven letters per week. If an incarcerated individual requires additional materials or postage for legal correspondence, an incarcerated individual may request these through the mailroom supervisor or designee. The mailroom supervisor shall grant the request for additional materials or postage for legal correspondence, unless it is determined that the postage provision is being abused, in which case the mailroom supervisor shall refer the request and findings to the managing official, or designee, for disposition. The mailroom supervisor shall encourage the indigent incarcerated individual to set mail priorities within the seven-letter allowance.
