:... national regulation as an alternative every single time. Especially when state rules vary greatly from state to state. It is the same reason that the auto industry tries over and over to kill the California EPA regs that conflict with national EPA regs. It costs a lot to tailor your business from state to state and adds a lot of lawyers and lobbyists to your payroll to deal with many government agencies. Much preferable to deal with only 1.
So just meet the most stringent (the CA Regs in this case) and you will (should?) meet the others. Their problem is trying the cut corners by having different versions instead of just one that will meet the most stringent version. I'd guess that the cost of going this way would be LESS than the cost of all those "lawyers and lobbyists to your payroll".
