(b) If the Service needs to amend your temporary access permit or operations permit, you will receive a written notice that:
(1) Describes the modification required and justification;
(2) Specifies the time within which you must notify the Service that you either accept the modifications to your permit or explain any concerns you may have; and
(3) Absent any concerns, specifies the time within which you must incorporate the modification into your operations.
