Revise contaminated property cleanup laws for dangerous drugs

This bill updates Montana's laws governing cleanup of properties contaminated with methamphetamine or other dangerous drugs by requiring contractors to be certified before they can represent themselves as qualified to perform remediation work. It establishes specific decontamination standards, setting a limit of 1.5 micrograms of methamphetamine per 100 square centimeters of surface material, and mandates that the state department verify when volunteer properties meet cleanup requirements while prohibiting a public list of such properties. The legislation also defines key terms like inhabitable property and volunteer property, outlines sampling requirements for testing, and authorizes the department to set training and certification standards for contractors and their employees, including provisions for fees to cover program costs.
