Design review stakeholders


Regulation 22 - Site Location and Design Approval Regulations for Domestic Wastewater Treatment Works was last amended by the Water Quality Control Commission (WQCC) in 2009.  On May 7, 2018, the WQCC held an informational hearing to obtain feedback regarding a proposed rulemaking scope to update the Site Location and Design Approval Regulation for Domestic Wastewater Treatment Works (Regulation 22). The WQCC agreed that the proposed rulemaking scope will benefit all parties by clarifying, improving, and modernizing the site location and design review processes. The scoping memo is available through the WQCC’s website.

Public comments received

We received 138 written comments on the proposed Regulation 22 and Regulation 61 draft proposals. We appreciate all of the written feedback, as well as the in-person feedback we received during the October 11, 2019 Main Workgroup stakeholder meeting.  We have considered and responded to each comment. 

Based on the October 11, 2019 stakeholder meeting, stakeholders and the department agreed to meet again on November 15, 2019 to further refine the draft proposal to the commission. Your participation will help build consensus on the few key remaining issues.

Proposed discussion

We would like to hold another stakeholder meeting to discuss the following:
  • Chemical approval form and framework.

  • Design capacity and pretreatment.

  • Other stakeholder specified items.
