(h) Modification or discontinuation of any mutual aid, letter of intent or contract or letter of agreement.

(3) Notification by facsimile or email will be considered written notice.

(4) Failure to report significant changes in the plan could result in the loss of plan approval.

(5) If the proposed change to the plan is to be made permanent, the rail plan holder then shall have thirty calendar days from notification to ecology to distribute the amended page(s) of the contingency plan to ecology for review and approval.

(6) If ecology finds that, as a result of a change, the plan no longer meets approval criteria; ecology may place the plan into conditional approval or disapprove the plan.
