The Office may for good cause shown suspend or revoke the
authorization of any self-insurer. Failure by a self-insurer to comply
with any provision or requirement of law or of the regulations in this
part, or with any lawful order or communication of the Office, or the
failure or insolvency of the surety on his indemnity bond, or
impairment of financial responsibility of such self-insurer, may be
deemed good cause for such suspension or revocation.
