MITIGATED NEGATIVE DECLARATION

PACIFIC GAS AND ELECTRIC COMPANY APPLICATION NO. 00-05-035 TO ESTABLISH MARKET VALUE FOR AND SELL ITS RICHMOND-TO-PITTSBURG FUEL OIL PIPELINE AND HERCULES PUMP STATION

SAN PABLO BAY PIPELINE COMPANY APPLICATION NO. 00-12-008 TO OWN AND OPERATE THE RICHMOND-TO-PITTSBURG FUEL OIL PIPELINE AND HERCULES PUMP STATION AS A COMMON CARRIER

PROJECT DESCRIPTION

Pacific Gas and Electric Company (PG&E) has submitted an Application (No. 00-05-035) to the California Public Utilities Commission (CPUC) seeking authority under Section 851 of the Public Utilities Code to sell its heated Richmond-to-Pittsburg Fuel Oil Pipeline to a new owner, the San Pablo Bay Pipeline Company (SPBPC), a subsidiary of Tosco Corporation. In a separate application (No. 00-12-008) to the CPUC, SPBPC is seeking authority under Sections 216 and 228 of the code to own and operate the Richmond-to-Pittsburg Fuel Oil Pipeline and Hercules Pump Station as a common carrier pipeline corporation. The proposed sale includes the pipeline from its point of origin in Castro Street (adjacent to General Chemical’s facility) in the City of Richmond, to the Pittsburg Power Plant, formerly owned by PG&E, located in the City of Pittsburg and includes the Hercules Pump Station, located in the City of Hercules. The Richmond to Pittsburg Pipeline and Hercules Pump Station would be sold in their current "as-is, where-is, with all faults" condition.

Because the CPUC must now decide whether or not to approve the PG&E and SPBPC applications, the California Environmental Quality Act (CEQA) requires the Commission to be the lead agency and consider the potential environmental impacts that may occur as the result of its decisions and require feasibility mitigation for significant impacts that are identified.

The Richmond to Pittsburg pipeline system and the Hercules Pump Station are "operational" in the regulatory sense, in that PG&E has maintained all the needed permits and approvals and conducted all the maintenance and inspections that are required for an operating system. The pipeline has been approved for the transport of "oil, petroleum, and products thereof" (CPUC Decision No. 84448). PG&E ceased using the system for moving fuel oil to its Pittsburg Power Plant in 1982, though some oil was moved through parts of the system as recently as 1991. A 4,000-foot segment of the pipeline was removed in 1998 to allow construction of a railway station in the City of Martinez. Under an agreement between PG&E and SPBPC, PG&E has secured the necessary rights of way for a 4,000-foot replacement section in Martinez. If the sale were approved, SPBPC would be responsible for obtaining the requisite permits and approvals and constructing the 4,000-foot replacement section. The construction of the 4,000-foot segment and the resumption of oil movement through the system are a reasonably foreseeable activities that would occur as a result of CPUC approval of the two applications.

The CPUC has reviewed the impacts that would result from approval of the applications, including the sale of the pipeline by PG&E, the reconstruction of the missing 4,000-foot section of the pipeline in Martinez, CA, and the future operation of the pipeline and pump station by SPBPC. The CPUC has concluded that all potential impacts can be mitigated to less than significant levels. PG&E and SPBPC have agreed to incorporate all the proposed mitigation measures into the project, and the CPUC is requiring that these mitigation measures be implemented as a condition of approval of the applications. The CPUC is issuing this document for a 30-day review and comment period to the Parties of Record in Applications Nos. 00-05-035 and 00-12-008, other potentially affected agencies, and interested members of the public.

ENVIRONMENTAL DETERMINATION

The attached Initial Study analyzes the potential impacts to the environment that would result from and proposes mitigation measures for the sale of the pipeline and pump station by PG&E, the construction of the missing 4,000-foot section of pipeline, and operation of the facilities by SPBPC.

Based on the Initial Study, the approval of the two applications would have no impact or less than significant effects in the following areas:

Agriculture
Mineral Resources
Population and Housing
Recreation
Utilities and Service Systems

The Initial Study indicates that the approval of the applications would have potentially significant impacts in the areas of:

Aesthetics
Air Quality
Biological Resources
Cultural Resources
Geology and Soils
Hazards and Hazardous Materials
Hydrology
Land Use and Planning
Noise
Public Services
Transportation and Traffic

Each of the identified impacts can be mitigated to avoid the impact or reduce it to a less than significant level. The mitigation measures, all of which PG&E and SPBPC have agreed to include in the project, are as follows:
