Direct staff to proceed with necessary work items to initiate a franchise agreement as requested by the San Diego Pipeline Company. BACKGROUND: The. San Diego Pipeline Company (SDPC) has requested that the City and their company enter into a franchise agreement to cover the installation, operation and maintenance of two pipelines proposed to be constructed within certain public roadways within the City of Tustin. A copy of their initial letter request is attached for information. SDPC has an existing lO-inch pipeline facility currently located within an easement which was previously a part of the recently abandoned Atchison, Topeka and Santa Fe Rail road right-of-way. The section of this lO-inch pipeline through Tustin is delineated in green on Route Map R-SD6-1 attached to SPDC's letter dated 2-9-87. The proposed routing of a new lO-inch and 16-inch pipeline is shown in red on the same Route Map R-2D6-1. Recent conversations with the SDPC indicate their willingness to expand the proposed alignment as shown in red to extend the 10" pipeline replacement from Walnut Avenue and the abandoned AT & SF right-of-way easterly to future Tustin Ranch Road right-of-way and thence southerly along the future Tustin Ranch Road right-of-way to Edinger Street. SDPC has indicated in their letter that they transport approximately 30 million barrels of refined petroleum products each year through the existing pipeline facility. These products include all grades of automotive gasoline, diesel fuels, commercial aircraft turbine fuels and military jet fuels. Their letter also outlines their plan for 'leak detection and provides an outline for line shut-down procedures in the event a leak should occur. MARCH 26, 1987 PAGE TWO DISCUSSION- The purpose of the City Council's action on this matter is to determine if the City desires .to grant a franchise to SDPC as requested for the installation, operation and maintenance of two pipelines within the public street rights-of-way. In the event the Council desires not to grant a franchise, as indicated above, no further action is required; and, if they desire to grant a francise, several items will be required before finalization of said franchise. Some of these items include, but are not limited to the following: 1. Adoption of Resolution of Intention by City 'and the holding of a public hearing for same. 2. Conformance to all CEQA requirements/regulations. 3. Finalization/approval of the franchise agreement by the City Attorney's office. 4. Final determination of facility alignment/location within the Tustin City limits. Additional conditions of approval to be considered in the granting .of this franchise are; removal of the abandoned 10" pipeline where feasible, pressure grouting of any pipeline facilities remaining in place and soil investigations at specified locations to determine the indication of any past pipeline leaks. The granting of the requested franchise has certain advantages and disadvantages to the community as follows- Advantages 1. Installation of new pipelines with state of the art leak detection devices. 2. Elimination of active fuel line in close proximitY to residential units at various locations such as Packer's Square, Laurelwood, Peppertree and Tustin Meadows developments. 3. Elimination of the fuel line crossing the I-5 freeway on abandoned railroad bridge. Helpful in future freeway widening project and Tustin Ranch Road interchange project. Disadvantages 1. Disruption to traffic during the construction phase along Newport Ave., B'ryan Ave., Browning Ave., E1 Camino Real and Walnut Ave. 2. Additional exposure to third party excavations around fuel lines. MARCH 26, 1987 PAGE THREE SDPC has indicated that the yearly franchise fee based upon 1987 dollars would be approximately $1,500 for the 16-inch diameter pipeline which is the only facility to be activated initially. In the event the City Council desires to proceed with the granting of the requested franchise agreement, it is requested that they direct staff to proceed with same and initiate a Resolution of Intention to establish a time and place for a public hearing on said franchise agreement. Bob Ledendecker Director of Public Works/City Engineer BL:jm Attachments TO: FROM: SUBJECT: WILLIAM HUSTON, CITY IWlANAGER PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION SUPPLEINENTAL REPORT TO SAN DiEGo PIPELINE COMPANY'S REQUEST FOR PIPELINE FRANCHISE Under the discussion area, the San Diego Pipeline Company (S.D.P.C.) does not concur with the removal of the 10" pipeline where feasible, pressure grouting of any pipeline remaining in place and soil investigations at specified locations. As an alternate to these conditions, S.D.P.C. requests the following: The displacement of all remaining petroleum products from the abandoned sections of lO-inch pipeline with nitrogen, the abandoned sections to be pressurized with nitrogen to determine that the pipe is sound upon abandonment and, should the pressure tests fail, soils investigations would be conducted at specified locations to determine the indications of any past leaks. S.D.P.C. has also informed staff that their original estimate for the ~vearly franchise fee at $1,500.00 was low and the revised estimate is approximately $6,ooo.oo. It is my .understanding that S.D.P.C. will be available at the April 6th City Council meeting to answer any questions the Council may have. Bob Ledendecker Director of Public Works/City Engineer BL:jm Los Angeles, California 90017 213/486.-7780 J. A. Whitehw Pipeline Construction February 9, 1887 · ENG 19-0 (L.S. SD-6) ENG 13-1 (87120 - JN 0239) Mr. Bob Ledendecker Director of Public Works City Engineer CITY OF TUSTIN 300 Centennial Way Tustin, CA 92680 Dear Mr. Ledendecker: As we discussed in your office on January 28, 1987, San Diego Pipeline Company (SDPC), a public utility, common carrier, refined petroleum Products transportation company, is expanding its No .rw. alk to San Diego pipeline 'system by replacing certain sections of its originally installed 10-inch pipeline with 16-inch pipe. The 10-inch pipeline is not being abandoned, but is temporarily being removed from service and maintained for future use when the need arises. System expansion began in 1985 with the replacement of approximately 7 miles of pipe between Norwalk and Anaheim, 25 miles between south Tustin and Camp Pendleton, and 31 miles between Oceanside and Miramar Naval Air Station in San Diego. Two additional sections, 20 miles between Anaheim and south Tustin and 25 miles through Camp Pendleton, are now scheduled for replacement during 1987 and 1988. Due to recent urban buildup adjacent to our original right-of-way in certain areas of the northerly section, which includes the City of Tustin, emphasis is being placed on replacing this section first. As noted in green on the attached Route Map No. R-SD6-1, the original 10-inch line was installed in the City of Tustin between Newport Avenue and Browning Avenue in 1962 on a then existent Atchison, Topeka and Santa Fe railroad right-of-way. This right- of-way has since been abandoned and sections have been developed for commercial and residential use. Due to this development, we proposed re-routing the new 16-inch line and relocating the original 10-inch line in this vicinity as a part of our current expansion project. As shown in red on Drawing No. R-SD6-1, our new routing would extend southerly on Newport Avenue to Bryan Avenue and then follow Bryan Avenue easterly to our existing right-of-way on Browning Avenue. As also noted in red, the proposed new routing A .~qM Fe Southem Pacific Corflp~fly would extend across Interstate Highway I-5 on Browning Avenue to Walnut Avenue i-n order to eliminate the existing overhead cross- ing of I-5. Since this new routing will necessitate longitudinal en- croachments in several City of Tustin public roadways, it is proposed that SDPC enter into a franchise ~greement with the City of Tustin to cover installation, operation and maintenance of the newly constructed lines. SDPC and its sister company Southern Pacific Pipe Lines, Inc. (SPPL) has numerous similar franchises with cities and counties throughout California, including the County of Orange and City of Anaheim in your immediate vicinity. To expedite such a'franchise agreement, enclosed is a formal application for franchise addressed to the City Council of the City of Tustin and a Sample form of franchise resolution sug- gested for your use. Due to the recent accident that occurred on our originally installed 10-inch line in south Tustin, we recognize that the safety of any new pipeline installation is of paramount import- ance to the City of Tustin. Laboratory analysis of the ruptured joint of pipe and subsequent analysis of 47 sections of pipe that had previously been removed from the pipeline during relocations indicate that rupture occurred due to a manufacturing flaw in a substandard joint of pip~ that we can only assume was shipped inadvertently from the pipe mill due to human error. The pipe was manufactured in 1962 at Kaiser Steel's Fontana mill which had excellent quality control procedures. During recent years we have increased our inspection staff at pipe mills to assure us that all.phases of pipe manufacture are being covered, including the loading and shipping of fully inspected pipe. Enclosed is a recent magazine article that outlines current quality control procedures at American Steel Pipe,. the manufacturer of our 16-inch pipe installed in south Tustin in 1985. As dictated by the Federal Hazardous Liquid Pipeline Safety Act of 1979 and the California Pipeline Safety Act of 1981, State Fire Marshal's office has sole safety regulatory and enforcement authority over intrastate liquid pipelines such as SDPC's Norwalk to San Diego system. Ail such lines must be designed, constructed, operated and maintained in strict accordance with Part 195 of'Title 49 of the Code of Federal Regulations and with Sections 51010 through 51020 of the California Government Code. The 250,000 miles of interstate liquid pipelines operated since the early 1970's in accordance with Part 195 have compiled a safety record unparalleled by any other mode of transporta-tion. In this regard, SDPC currently transports approximately 30 million barrels of refined petroleum products each year through its Norwalk to San Diego system. This is equivalent to approximately 170,000 truck and trailer loads - 2 of 4 - per year which would otherwise be transported through Orange County. Products transported by SDPC include all grades of automotive gasoline, diesel fuels, commercial aircraft turbine fuels and military jet fuels. The design of a new pipeline, such as our proposed 16-inch line through Tustin, must take into account the probable cause of a pipeline accident, measures that can be taken to lessen the possibility of such accidents, and measures that can be taken to minimize the effects of accidents should they happen. In review- ing detailed statistics compiled by the Federal Department of Transportation (DOT) on the 190 accidents that were reported in 1982 on the 250,000-mile nationwide network of pipelines under its jurisdiction, we find that 66 involved third party damage, 61 were from internal or external corrosion and 63 from all other causes. The 63 accidents included 5 seam ruptures sach as occurred in Tustin in November, 1986, or 1 per 50,000 miles of pipeline. While third party damage remains our biggest concern, the adoption and use of Underground Service Alert (USA) by excavation contractors has greatly reduced accidents from this cause. In- stallations in public roadways also have the added protection of review and approval by agency staff prior to. excavation near the underground facility. The second major cause, corrosion, has been mitigated by the excellent coatings available today and cathodic protection applied to the completed pipeline. In addition, SDPC Periodi- cally, runs internal inspection tools through its lines to detect corrosion at its earliest stages, should it occur. SDPC's current leak detection system will be upgraded during 1987 with the installation of a new Supervisory Control and Data Acquisition (SCADA) system (description attached). The real-time monitoring features of this new system will immediately alert personnel involved in the direct operation of the line to an upset condition, such as changes in flow or pressure, as neces- sary to quickly shut down the pipeline and minimize spillage from a leak. The low point of the pipeline in the Tustin area is at about Milepost (M.P.) 26 shown on Drawing No. R-SD6-1. From this point the line slopes easterly for about 10 miles at + 0.75% and northwesterly for about .8 miles at + 0.59%. To minimize draindown should a leak occur in the Tustin area, a check valve will be installed adjacent to the existing block valve at M.P. 26.11 and a remotely operated gate valve will be installed at about M.P. 22.43 near the intersection of Newport Avenue and 4th Street. As I explained during our January 28 meeting, we are pro- ceeding with design and right-of-way procurement on a schedule that will allow a start of construction by about July 1 and would appreciate any help you could give in expediting our request. - 3 of 4 - Should you have any questions, please do not hesitate to contact me at 213/486-7780. sincerely, J.A.

When complete, the system will have state-of- the-art computerized control to monitor the pipeline and to assist operators in making key decisions pertaining to pipeline operations. NEW SCADA SYSTEM EQUIPMENT The new SCADA system is centered around General Electric Series 6 Programmable Controllers. These are' utilized both as remote terminal units, as well as at hub locations. Key parameters of pipeline operations are 'displayed on color cathode ray tube screens (CRTs). The operators control the pipeline through touch screen procedhre.s. SAN.DIEGO PIPELINE OPERATIONS Key operating locations on the San Diego Pipeline system are Watson (the originating pump station and tank farm), Orange (an intermediate terminal and pump station), and Mission Valley Terminal in San Diego. These locations are manned 24 hours a day, 7 days a week with operating personnel. The new SCADA system will provide information to assist the operator if a leak is occurring in 'one of several ways. First, by showing the rate of change in pipeline Pressure or rate of change of pipeline flow, which would be indicated at the operating location where the change was occurring. Secondly, a comparison of in and out volumes would be shown on the SCADA system .at Watson. Thirdly, the Los Angeles control center would receive information on volumes in and out of the pipeline system as well as pressures at alt locations. And fourthly, a central computer in Los Angeles would monitor the key parameters of the pipeline as it operates, and through a sophisticated software program determine if a likely leak or upset condition is occurring on the pipeline. TIMING OF INSTALLATION It is planned that the above described' SCADA system will be installed and operational on the San Diego Pipeline prior to the end of 1987. ~0 0 0 m · SANTA ~A (CHECK) TUSTIN /. / /
