This bill directs the Department of Environmental Quality to amend existing regulations (DEQ4) to permit the use of drain systems in areas that have undergone cutting or filling for new subsurface wastewater treatment systems. The amendment aims to facilitate the installation of these systems in modified landscapes, potentially improving wastewater management in such areas.

Additionally, the bill includes an immediate effective date, ensuring that the changes to the regulations can be implemented without delay. This prompt action is intended to address current needs in wastewater treatment and enhance environmental quality in regions where land alterations have occurred.
