California Code, Penal Code - PEN § 3415

(a) The probation department shall, no later than the day that any woman is sentenced to the state prison, notify such woman of the provisions of this chapter, if the term of the state imprisonment does not exceed six years on the basis of either the probable release or parole date computed as if the maximum amount of good time credit would be granted. The probation department shall determine such term of state imprisonment at such time for the purposes of this section.

(b) The woman may, upon the receipt of such notice and upon sentencing to a term in state prison, give notice of her desire to be admitted to a program under this chapter. The probation department or the defendant shall transmit such notice to the Department of Corrections, and to the appropriate local social services agency that conducts investigations for child neglect and dependency hearings.
