§ 151. Work Release Program. The department shall establish work\nrelease programs for prisoners sentenced to New York City correctional\ninstitutions. The commissioner may extend the limits of the place of\nconfinement of a prisoner as to whom there is reasonable cause to\nbelieve he will honor his trust by authorizing him to participate in a\nwork release program in the community on a voluntary basis while\ncontinuing as a prisoner of the institution or facility in which he is\nconfined. An extension of limits shall be under such prescribed\nconditions and for such reasonable hours or reasonable periods of time\nas the commissioner deems necessary. Such extension of limits may be\nwithdrawn at any time.\n
