Individual/Subsurface Sewage Disposal: Docket No. 58-0103-1901

Rulemaking initiated in response to challenges made in enforcing and updating portions of the Technical Guidance Manual for Individual Subsurface Sewage Disposal Systems (TGM).

Status of Rulemaking

Pending rule revisions included in Omnibus Docket No. 58-0000-2100.


This rulemaking was initiated in response to challenges made in enforcing and updating portions of the Technical Guidance Manual for Individual Subsurface Sewage Disposal Systems (TGM). The rules currently only specify the requirements for standard individual/subsurface sewage disposal systems to be installed in Idaho, while leaving the majority of the requirements for alternative/proprietary systems in the TGM.  Currently, if a standard system cannot be installed on a parcel, an alternative system may be permitted if it is approved by the Director and in accordance with the recommendations of the Technical Guidance Committee as documented in the TGM.

This proposed rule revises the Individual/Subsurface Sewage Disposal System Rules and Rules for Cleaning of Septic Tanks, IDAPA 58.01.03, by adding into the rules requirements applicable to facilitate the permitting, design, and construction activities for alternative and/or proprietary systems currently in the TGM. The proposed rule also clarifies the operation and maintenance requirements currently required for all systems as well as service provider responsibilities and provides the basis under which approved systems may be revoked or amended.
