Idaho's air quality rules get simpler, removing old federal standards

Idaho just updated its air quality regulations. The state removed outdated rules and simplified language, making them easier to understand and follow. This means the state's environmental agency can focus on current federal standards without old, confusing text.

States often adopt federal environmental standards by reference, meaning they copy the federal rules into their own laws. Over time, these state laws can become cluttered with references to federal rules that have since changed or been repealed. Cleaning up these rules makes it easier for businesses to comply and for regulators to enforce. It also reduces the chance of legal challenges based on outdated or ambiguous language.
