The new conference report makes the following changes to the 4th edition. 

Amends GS 143-350 to add the termpretreatment mixing basin, meaning a basin created from lands that do not include waters of the state and in which raw water is mixed with reclaimed water before it is treated to the standards to make it suitable for potable water supply.

Amends GS 143-355.5 to amend the conditions that must be met in order for a local water supply system to combine reclaimed water with other raw water sources before treatment to replace the term "impoundment" with "pretreatment mixing basin." Adds to those conditions that any discharge into the waters of the state must be pursuant to a permit issued under GS 143-215.1. Amends (b) to provide that the standards adopted concerning standards for reclaimed water systems that are adequate to prevent direct distribution of reclaimed water as potable water must not prohibit the combining of reclaimed water with other raw water sources before treatment.

Deletes the provision requiring the Department of Environment and Natural Resources, in consultation with the Environmental Management Commission, to study the effects of chemicals of emerging concerns in wastewater effluent from municipal and privately operated wastewater treatment plants and in source water supplies.
