I ccamenced my employment with the predecessor to ARCO Pipe Line in 1946, at which time I was involved with operational activities at a pumping station and terminal facility. In 1947, I worked as a pipe line dispatcher. In 1950, I worked in Product Quality Control as a Delivery Supervisor. From 1960 through 1970, I worked in the Land and Right-of-Way office, which is responsible for acquiring land for pipelines, protecting easements from encroachment and development, working with developers and acting as a liaison with property owners. In 1970, I became District Department Supervisor of this office. In July 1982, I became Acting District Manager, and in April 1983 I became the District . Manager. Q4. Are you familiar with an ARCO pipe line that traverses Chester and Montgomery Counties, Pennsylvania? A4. Yes. This is known as the 8" Northeast Boot to Fullerton Pipe line. It runs approximately 49 miles from the Boot Pumping Station to the Fullerton Terminal. Q5. Are you aware of its physical relationship to the Limerick Generating Station and, if so, on what basis? AS. Yes. Numerous on-site inspections have been conducted by ARCO Pipe Line on this site since 1970. At that time, ARCO identified and staked out the pipe line route as it passes Limerick. In conjunction with my respon- sibilities as Department Supervisor for Land and Right-of-Way activities, I personally inspected this site ._ _-__ . _ _ _ _ _ - - - _ - - _ _ _ . .. - . & ' -3- , , and consulted ARCO maps and photos demarcating the pipe line route. - Q6. How is the pipe line right-of-way at road cross- ings identified? A6. Signs which meet industry and U.S. Department of Transportion standards are mounted on metal posts identify- ing the center line of the pipe line. Q7. Describe the design and configuration of this pipe line. A7. The 8" diameter Northeast Boot to Fullerton line is 48.87 miles long, and utilizes X 42 grade steel'of .250 thickness. The pipe is, as noted, eight inches in diameter and coated with a coal tar enamel. The pipe line has a capacity of 31,700 barrels per day and operates at a maximum pumping pressure of 1,100 psig. ' Normal operating pressures for gasoline are 850 to 875 psig and for diesel and furnace oil, 950 to 1,000 psig. The pipe line was buried at least three feet below grade at the time it was constructed in 1955. Q8. Describe the protection of this pipe line against corrosion. A8. The pipe line is coated with coal tar to protect against corrosion. Additional protection against corrosion is afforded by the impressed current cathodic protection system. ; 09. Identify the products carried by the pipe line. - - . _ . .- _ . - . _ . , . _ . - _ _ , . , _ _ . , . , _ . _ . _ _ , . _ . _ _ . _ . _ _ _ . _ _ _ . , _ . _ _ - , . _ , - _ _ _ __ __ * -4- . A9. The pipe line carries automobile gasoline, kerosene, diesel oil, and home heating oil. ARCO Pipe Line has stipulated in an amendment to its right-of-way agreement with Philadelphia Electric Company that it will not carry propane through the line. The pipe line has never carried butane or liquified natural gas a,nd could not carry either product without major physical modification of the pipe line. Although the pipe line could carry aviation fuel, which is simply a higher octane gasoline than used for automobiles, to my knowledge, the line has never been used for this purpose. The present tariffs on file with the Pennsylvania Public Utilities Commission cover transportation of the following: gasoline, kerosene, jet engine fuel, tractor fuel, diesel fuel, and light and medium fuel oil. 010, Describe the nearest pumping station above and below the point at which the pipe line passes closest to e Limerick. A10. There is no pumping station above Limerick since the pipe line terminates at Fullerton. The Boot Pumping Station, located in the vicinity of West Chester, Pennsylvania, is approximately 1535 miles from the point at which the pipe line passes closest to Limerick. Oll. Is the Boot Pumping Station manned or remotely controlled? All. A'ctivities at the Boot Pumping Station ae remotely controlled from ARCO Pipe Line's Point Breeze - _ _ _ _ - _ _ _ - _ _ _ _ _ | -5- . Pumping Station, located in Philadelphia as well as from the Pipe Line Control Center in Independence, Kansas. Each of these facilities provides continuous monitoring and are equipped to regulate pumpages, open and close the pipe line, and shut down the pumps. Q12. Describe periodic inspection and maintenance of the pipe line that passes near the Limerick Generating Station which would provide additional information regarding leaks. A12. ARCO Pipe Line conducts weekly aerial inspections of the pipe line. Dead vegetation along the pipe line route would indicate possible leakage of products. Where the pipe line passes near a stream or. body of water, a rainbow on the water could also indicate the possibility of a leak. Finally, leakage could be detected during right-of-way maintenance activities, such as brush clearing. Q13. Describe the devices and procedures utilized for detecting leaks in the pipe line. A13. As noted, pipe line flow is electronically moni- tored by remote control facilities at the Point Breeze Pumping Station in Philadelphia and the pipe line control center in Independence, Kansas. Specifically, pipe line flows are electronically monitored at terminals located at Sassamansville (Swann Oil) , 23.36 miles downstrear. of the Boot Pumping Station, at Macungie (Buckeye Pipeline Compa- ny), 36.59 miles from the Boot Pumping Station, and at .Fullerton Distribution Terminals, 48.87 miles from the Boot , ' ' -. _ _ _ _ _ _ . _ _ _ _ _ _ _ _ _ . _ _ . _ _ _ _ _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ __ ___ _______ - -6- , Pumping Station. Both Point Breeze and Independence have independent capability to detect from this continuous feedback of information in 1 psig difference in pressure levels. Q14. Upon detection of a leak by remote monitoring, what systems and procedures are available to stop pumpages? A14. An instantaneous, complete rupturing of the pipe line would result in immediate reduction in line pressure. For tt$e products carried in the 8" Northeast Boot to Fullerpon linE., ARCO has set the low outlet pressure control at Boot at 365 psig. Thus, a loss of pressure at the Boot Pumping Station below this level, at any time, would be detected by a sensor there, which would result in an immedi- ate, automatic shutdown of pumpages. Assuming a rupture severe r ..ough to result in a loss of pressure below the low outlet pressure control level, the sensor would be activated within a matter of a few minutes. Additionally, the same flow information would be monitored by the Point Breeze Pumping Station and the Pipe line Control Center at Indepen- dence, and either facility could provide independent backup shutdown capability. In addition to these automatic shutdown features, the pipeline's monitoring system permits prompt detection and isolation of any leakages which are less substantial. It must be understcod that slight differences in pressure may be caused by ordinary operational functions of the pipe line, such as ambient temperature changes and pressure I .. _ _ _ _ _ _ - _____ _ __ _ _ _ _ _ _ _ _ _ - _ _ _ _ _ _ _ _ _ _ _ -7- , differences for the products pumped. Any sudden indication of a radical pressure change, e.g., 100 psig, however, would cause monitoring personnel to take a closer look at the flow informaticn to determine whether the Boot Pumping Station should be shut down. Also, there is a continuous monitoring of product delivery information as flows are taken off line at downstream stations. Thus, if information as to line pressure and product inventory at the - various terminals indicates a posrible leak, the pipe line would be shut down from either of the remote facilities. In the meantime, the Pipe Line Control Center at Independence would contact the ARCO Montello District Office with information as to the general location of the pipe line section where the leak is suspected. While further analysis is underway, a fully equipped " spill truck" is crew-readied and upon confirmation of the leak's location would be dispatched from the District office.
