How regulations work: If there is a national regulation, law, or standard ( I'm going to abbreviate RLS) it serves as the bare minimum requirement for the entire country. State and local RLS can be adopted if they meet or exceed the federal standards. States cannot and should not be allowed to opt out of any national standards, laws, or regulations. If they want to add to them then so be it. This system has been in place for decades and works very well to provide a uniform protections and standards for the American people. To break up enforcement of our national / federal laws, regulations, and or standards is to break up the United States of America. Republicans are trying to further divide up our country. Do not let them do it.
