Resolution G-3297. Sempra Energy on behalf of San Diego Gas and Electric (SDG&E) requests approval of its Emergency Proposal to Temporarily Revise Gas Transportation Service Level for Electric Generation Customers (Gas Rule 14). Sempra's request is denied. SDG&E is ordered to curtail the Rosarito plant first. The Commission shall open an Investigation (OII) into the activities of Sempra Energy, Southern California Gas (SoCalGas) and San Diego Gas and Electric (SDG&E) with regard to the planning of the SDG&E gas transmission system and transmission service to the Rosarito plant.
By Advice Letter 1210-G Filed on August 1, 2000.

SUMMARY
With this Emergency filing, SDG&E proposes to modify, on a temporary basis, the gas transportation service level elections of those customers with an average daily gas usage of 15 million cubic feet from firm noncore service to interruptible noncore service.
SDG&E filed this emergency advice letter on August 1, 2000 and requested a shortened protest period of five days, and an effective date of August 8, 2000. SDG&E requested the tariff change be temporary, from the effective date to November 1, 2000. The request for a shortened protest period was not granted and the normal 20 -day protest period prevailed.
Seven protests were filed by: California Independent System Operator (ISO), August 7, 2000; Air Pollution Control District, County of San Diego, August 7 and 21, 2000; Electric Generator Alliance (EGA) representing Cabrillo Power and Duke Energy North America, August 7, 2000; Air Resources Board, August 8 and 21, 2000; Utility Consumers' Action Network (UCAN) and Environmental Health Coalition, Joint Protest, August 13, 2000; City of Carlsbad, August 15, 2000; and the American Lung Association, August 17, 2000.
SDG&E responded to the protests of the California Independent System Operator (ISO), Air Resources Board, Air Pollution Control District County of San Diego, and Cabrillo Power and Duke Energy North America on August 14, 2000 and to the protest of UCAN and the Environmental Health Coalition on August 23, 2000.
This Resolution denies SDG&E's request for approval of its Emergency Proposal contained in Advice Letter 1210-G filed August 1, 2000 to Temporarily Revise Gas Transportation Service Level for Electric Generation Customers (Gas Rule 14).
In the event a curtailment of gas transportation is necessary due to system capacity constraints, SDG&E shall be required to curtail the Rosarito plant first and only during each and every curtailment until adequate capacity is built to support the Rosarito load. In the event the total capacity utilized by the Rosarito plant at the time a curtailment is called is not adequate to support the required necessary reduction, the remaining amount of load to be curtailed shall be taken from all other power plants in SDG&E's territory, on a pro rate basis, simultaneously.
SDG&E shall file an advice letter making the revisions to curtailment procedures discussed herein to San Diego Gas Tariff Rule 14 within five days of approval of this Resolution.
