Regarding the three posted questions:

#1 - I believe that the pollution should cover leaves, brush and others as mentioned in the regulations.  It is particularly frustrating when burning keeps me from taking my kids out during the day for concern of their health.  While these may essentially be local issues, the localities do not seem to be interested in monitoring or dealing with those issues.  If the state does not provide controls and specific guidance then I do not believe that most localities will address the problems. 

#2 - I like the idea of just whether or not collection service is available.  If we are trying to protect our environment, homes, and families from what is clearly identified as bad for us then we should avoid such activities whenever possible.  For those that aren't concerned with burning, they should not be able to decide for others (by being permitted to burn).  If the guidelines are tightened to anywhere public or private collection is available then the people will have the choice of composting or disposing of their debris without being able to affect other people around them.

#3 - If it is an appropriately controlled and monitored disposal facility, that may be better than disposing of the material on-site.  I do think that the language should be careful to not allow for people to drag their waste into each others yards or just anywhere off-site - the off-site option should always be a better disposal option than on-site.
