This is the proposed decision of Administrative Law Judge (ALJ) Gottstein. It will be on the Commission's agenda at the next regular meeting 30 days after the above date. The Commission may act then, or it may postpone action until later.
When the Commission acts on the proposed decision, it may adopt all or part of it as written, amend or modify it, or set it aside and prepare its own decision. Only when the Commission acts does the decision become binding on the parties.
Parties to the proceeding may file comments on the proposed decision as provided in Article 19 of the Commission's "Rules of Practice and Procedure." These rules are accessible on the Commission's website at http://www.cpuc.ca.gov. Comments should be served by both electronic and U.S. mail on all appearances and the state service list in this proceeding. Pursuant to Rule 77.3 opening comments shall not exceed 15 pages. Finally, comments must be served separately on the ALJ and the assigned Commissioner, and for that purpose I suggest hand delivery, overnight mail, or other expeditious method of service.
