North Carolina Greywater Code
The session law provides interim standards for use of gray water for hand-watering inedible plants that will sunset when rules adopted by the Commission for Health Services go into effect .
This is quite a strange law. As part of an emergency bill, untreated graywater reuse is allowed but only using buckets / watering cans or other handheld containers.
It would appear the State only wants to conserve water when the state has already achieved a drought crisis.

In developing the rules, the Commission shall review the provisions set out in subsection (c) of this section.
