extension of the 30

- day comment period may be granted if the request for an extension adequately explains why more time is required to prepare comments. All comments received prior to the end of the public comment period and all comments made during a public hearing will be considered in arriving at a final decision on the permit. The final permit is a public

record that can be obtained upon request. A statement of reasons for changes made to the draft permit and responses to comments received will be sent to all persons who commented on the draft permit.

If you believe any condition of the draft permit is inappropriate or that our initial decision to deny an application, terminate a permit, or prepare a draft permit is inappropriate, you must raise all reasonably ascertainable issues and submit all reasonably ascertainable arguments supporting your posi tion by the end of the comment period.
