(b) The Labor Commissioner shall provide that an interpreter be present at all hearings and interviews where appropriate.

(c) The Labor Commissioner shall prepare and distribute to the public, through its local offices, materials explaining services available in non-English languages, as well as in English. In addition, the commissioner shall prepare and use written materials in non-English languages as well as in English for use by local offices if the local office serves a substantial number of non-English-speaking people, as defined in Section 7296.2 of the Government Code.
