Regulations & Permits

We oversee many state and federal laws designed to protect Washington's land, air, and water. Rules and regulations that direct state agencies, local governments, businesses, and others on how to comply with relevant laws are compiled in the Washington Administrative Code. See our laws, rules, & rulemaking page for more information about our current rules and rulemaking.
