The laws in the Montana Code Annotated are passed by the Montana State Legislature, which consists of the Montana House of Representatives and the Montana Senate. DEQ is charged with protecting a clean and healthy environment as guaranteed to our citizens by our State Constitution in Titles 75, 76, and 82, Montana Code Annotated.
DEQ is responsible for administering and enforcing several chapters of rules within Title 17 of the Administrative Rules of Montana (ARM). The links below to the specific chapters on the Montana Secretary of State website are provided as a convenience for interested parties. Administrative rules are periodically reviewed and revised by DEQ and some lapse in time may occur between adoption and the electronic posting of new or revised rules. Electronic rules on the Secretary of State website are updated quarterly and may not reflect the most current version adopted. For an official version of the Administrative Rules of Montana, please contact the Secretary of State at (406) 444-2055.
