IT IS ORDERED that:

1. Southwest Gas Corporation (Southwest) shall file, within 10 days of the effective date of this decision, revised tariff schedules for gas rates as set forth in Appendices D and E of this order. The revised tariff schedules shall reflect a four-year phase-in of the additional revenue requirement adopted in this order for Northern California. The phase-in of the additional revenue requirement shall be according to the following schedule: 80% in 2003; 10% in 2004; 5% in 2005, and 5% in 2006. In addition, Southwest is authorized to amortize the current balance in the Revenue Recovery Shortfall Memorandum Account (RRSMA) in rates for 2003 and 2004.

2. Southwest's revised tariff schedules shall become effective thirty days after the effective date of this decision, and shall comply with General Order 96-A.

3. Southwest shall close the RRSMA effective with the date of this order.

4. Southwest is authorized to establish a revenue balancing account to track the differences between actual sales and sales adopted in this order. The revenue balancing account shall become effective no earlier than 30 days after the effective date of this order.

5. Southwest may continue to include pipeline demand charges, fixed storage charges and core margin revenue in the Core Fixed Cost Adjustment Mechanism.

6. Southwest is directed to develop discrete rate components for its interstate pipeline demand charges in its next General Rate Case (GRC).

7. Southwest is authorized to implement the public purpose program surcharge adjustments contemplated in D.03-03-007, shown on Appendix C.

8. In its next GRC, Southwest shall provide the Commission with an independent audit administered under the trustees of the Post Retirement Benefits Other than Pensions (PBOPs) trust account that clearly explains, when and how Southwest will use its PBOPs trust account to fund retiree's PBOPs expenses.

9. In its next GRC, Southwest must justify the reasonableness of the $30 million in software projects currently included in Construction Work in Progress balances before any of these amounts may be included in plant-in-service for rate recovery.

10. Southwest shall file with the Commission (the Director of Energy Division) annual reports addressing Southwest's pipeline replacement program beginning November 1, 2004, with subsequent reports on November 1, 2005, and November 1, 2006. The reports shall be in the same form as those filed by Pacific Gas and Electric Company, and included as Exhibit 103 in this proceeding.

11. Southwest is authorized to file advice letters and supporting workpapers requesting attrition year adjustments to rates for 2004, 2005, and 2006. The attrition year adjustments shall be calculated consistent with the Office of Ratepayer Advocates modified attrition year proposal, and may include an index adjustment based on a seven-year constant dollar historical average of non-pipeline replacement-related capital expenditures. Southwest is authorized to include revenue requirements for attrition in addition to revenue requirements that are phased-in during the four-year phase-in period.

12. Southwest is authorized to include the revenue requirements for its Truckee Operational Center in its Northern California attrition request beginning 2004. The revenue requirement for the Truckee Operations Center shall include supporting workpapers.

13. Application 02-02-012 is closed.

This order is effective today.

Dated March 16, 2004, at San Francisco, California.
