California Code, Public Utilities Code - PUC § 879

(a) The commission shall, at least annually, initiate a proceeding to set rates for lifeline telephone service. All telephone corporations providing lifeline telephone service shall annually file, on a date set by the commission, proposed lifeline telephone service rates and a statement of projected revenue needs to meet the funding requirements to provide lifeline telephone service to qualified subscribers, together with proposed funding methods to provide the necessary funding. These funding methods shall include identification of those services whose rates shall be adjusted to provide the necessary funding.

(b) The commission shall commence a proceeding within 30 days after the date set for the filings required in subdivision (a), giving interested parties an opportunity to comment on the proposed rates and funding requirements and the proposed funding methods. The commission may change the rates, funding requirements, and funding methods proposed by the telephone corporations in any manner necessary, including reasonably spreading the funding among the services offered by the telephone corporations, to meet the public interest. Within 60 days of the annual filing, the commission shall issue an order setting lifeline telephone service rates and funding methods for each telephone corporation making a filing as required in subdivision (a). The commission may establish a lifeline service pool composed of the rate adjustments and surcharges imposed by the commission pursuant to this section for the purpose of funding lifeline telephone service.

(c) Any order issued by the commission pursuant to this section shall require telephone corporations providing lifeline telephone service to apply the funding requirement in the form of a surcharge to service rates which may be separately identified on the bills of customers using those services. The commission shall not allow any surcharge under this section on the rates charged by those telephone corporations for lifeline telephone service.

(d) The commission shall permit telephone corporations operating between service areas to adjust the rates of any service which may be affected by any surcharge imposed by this section.
