(b)
A permit may be revoked upon request of the permittee or under either of the following procedures:

If, after an investigation other than a hearing on a petition for extension of time, it appears that cause exists to revoke a permit, the board shall give notice of proposed revocation in writing, mailed in a sealed, prepaid postage and certified letter to the permittee at his or her last known address. If the permittee fails to request a hearing with the time provided under Section 1410.1, the board shall revoke the permit and declare the water subject to appropriation.
