H 593 Idaho House · 68th Legislature, 2nd Regular Session (2026)

DEPARTMENT OF ENVIRONMENTAL QUALITY – Amends and repeals existing law to remove reference to outdated or unnecessary provisions.

H 593 amends and repeals outdated provisions in Idaho Code related to the Department of Environmental Quality. It removes an obsolete definition in Section 39-5803, deletes outdated references in Section 39-5804, and repeals several sections - including those governing the State Hazardous Waste Management Planning Committee and the State Hazardous Waste Management Plan - as well as a chapter on Big Payette Lake water quality. The bill streamlines Idaho’s environmental laws by eliminating unnecessary language, without changing current environmental protections or requirements. This cleanup effort aims to make the legal framework more current and efficient for public and governmental use. The bill passed unanimously in the Idaho House of Representatives.
