Please submit comments by replying to this blog post or by email to Gerard.Martin@state.ma.us.
[MassDEP will accept comments throughout the summer, but comments submittede earlier in the summer will be more readily considered in the next draft that is currently being developed by MassDEP staff.  Be reassured, however, that ALL comments received will be considered for either the next or subsequent drafts… we won’t discard them.]
