2023 Regulation Updates

Introduction

The amended 18 AAC 72 Wastewater Treatment and Disposal Regulations effective October 1, 2023 were significantly reorganized, including a major expansion in permit-by-rule or authorization-by-rule processes which allows more wastewater systems to be installed without prior approval from the department as compared to the prior version amendments through November 7, 2017. This page includes resources and outreach activities in regards to the overall changes, and detailed descriptions of new or revised regulations, as well as providing references in current regulations for comparison. If you have additional questions please contact the Engineering Support and Plan Review Section Manager or local area office staff.
