Rule Development - Biosolids Management Chapter 173-308, WAC

Adopted: May 24, 2007
Effective: June 24, 2007


In April 2006 the Department of Ecology (Ecology) began the process to amend the existing rule, Chapter 173-308 WAC, Biosolids Management. This rule established requirements for handling biosolids in the state. Chapter 173-308 WAC was adopted on February 18, 1998 in accordance with Chapter 70.95J RCW.

This rule making proposed amendments to:
  • Streamline the permitting process requirements
  • Better address septage management requirements
  • Develop a more thorough and equitable fee structure
  • Address “general housekeeping” issues such as providing clarifications, making formatting changes, and ensuring that the rule is consistent with the new Biosolids general permit and previous interpretations and policy decisions.
The revisions will impact all facilities subject to the biosolids rule, including wastewater treatment plants (WWTPs) and Septage Management Facilities (SMFs).
