Good question.
The limitation is that the activity would have to contribute to air pollution. To be candid, we haven't thought through exactly how we would circumscribe that, except that it would be focused on air pollution.
Also, I draw your attention to the fact that there are considerable authorities in the act that are given to the targets of information collection to either argue that the information shouldn't be collected or to argue that the information constitutes confidential business information. We're not proposing to change or weaken those provisions in any way.
