Mass. Gen. Laws ch. 127, § 83E

The commissioner is hereby authorized to establish, on land under the control of the department of environmental management and upon sites approved by the commissioner of environmental management, or wherever authorized by the governor and council, camps to which male prisoners may be transferred prior to their release upon parole. The commissioner may transfer to any camp so established any prisoner whose parole has been approved by the parole board unless otherwise recommended by the parole board. Such camp shall provide such training and preparation for release as will best enable the prisoners to attain successful readjustment within the community.
