This is a silly comment as your state-equivalent EPA standards do change with every state. The federal EPA’s standards are a minimum. Many states go above that minimum to varying degrees. California is notorious here: they’re called CalEPA. Same with workplace safety where CalOSHA is significantly more stringent than OSHA. Not only that, but many laws change from state to state. Can you imagine trying to run a business when employment laws vary state to state? Can you imagine trying to run a business when statutes of limitation vary from state to state? Can you imagine trying to run a business where manufacturer or products liability changes from state to state? No need to imagine: it’s happening every day!
