Incorrect. You assume because the phrase "modification of this permit" is used that it means an "application" is required and that the submission will appear on the website like permit modifcation applications seem to do. You may be right and you may be wrong.
As I noted in my edit, I see no language indicating a "modification application" is needed.
And worth noting is that JBI used the language "apply" and "application" when discussing the 2 to 4000 pound change. When referenceing the changing of the SW permit, JBI uses the word "amend". I find that interesting:-)
