(a) BLM will give you written notice of any defaults, breach, or cause of forfeiture, either in person or by certified mail. You have 30 days after receiving the notice:

(1) To correct all defaults;

(2) To request an extension of time in which to correct the defaults; or

(3) To submit evidence showing to BLM's satisfaction why we should not cancel your contract or free use permit.

(b) If you fail to respond to the notice under paragraph (a) of this section, or if delivery of the notice is refused, or not completed as described in §1810.2 of this chapter, BLM may cancel the contract or permit.
