(b) The regional center or state-operated facility shall send adequate notice, as described in Section 4701, no more than five business days after it makes a decision to deny the initiation of a service or support requested for inclusion in the individual program plan unless there is mutual consent as defined in subdivision (k) of Section 4701.
