(b) Subject to subdivision (a), the review period provided for in section 41(3) shall be 42 days instead of 63 days.

(c) When a planning commission sends notice to an entity under section 39(2) that it intends to prepare a subplan, the notice may indicate that the local unit of government intends not to provide that entity with further notices of or copies of proposed or final subplans otherwise required to be submitted to that entity under section 39, 41, or 43. Unless the entity responds that it chooses to receive notice of subplans, the local unit of government is not required to provide further notice of subplans to that entity.
