DEQ seeks comment on proposed revisions to subsurface sewage disposal systems guidance manual

Wednesday, January 09, 2019

BOISE — The Idaho Department of Environmental Quality (DEQ) is seeking public comment on proposed revisions to its guidance on how to design, construct, and operate subsurface sewage disposal systems.

The proposed revisions to the Technical Guidance Manual for Individual and Subsurface Sewage Disposal Systems (TGM) address property owner operation, maintenance, or monitoring requirements; pressurization units; sand mound absorption bed cell design; and approved nondischarging products.

The TGM is a web-based reference document used by builders and on-site wastewater system installers to select, design, and install subsurface sewage disposal systems to meet state requirements and by DEQ and public health districts to evaluate the site, proposed design, and construction of subsurface sewage disposal systems.

The changes are designed to ensure the TGM reflects current public health standards.

The proposed revisions, indicated in red and blue ink, are available for review on DEQ's website (download at right).

Submit written comments on the proposed revisions by February 8, 2019, at 5 p.m MST below or by mail or email to:
